TECHNICAL FIELD
[0001] This invention relates to an anti-tamper combination (for example, assembly) to initially prevent, but subsequently allow, communication between the outside and the inside of a system. BACKGROUND OF THE INVENTION AND TECHNICAL PROBLEMS PRESENTED BY THE PREVIOUS TECHNIQUE
[0002] Closures are employed to selectively prevent or allow communication between the outside and inside of a system (eg, machine, equipment, containment system (including bottles and bags), etc.) through an opening in the system. A typical closure includes (1) a receiving structure (for example, a body, base, accessory, etc.) in an opening into the system and (2) a closing element (for example, a cover, cover, overcap, etc.).
[0003] The reception structure can typically be either (1) a separate structure that (a) can be attached to such a system opening and (b) defines at least one access passage through the reception structure to communicate via such a system opening with the interior of such a system and (2) an integral structure that is a unitary portion of such a system and that defines at least one access passage through the integral structure so that the access passage functions as the opening, for you, for the system.
[0004] The locking element typically accommodates movement relative to the access passage of the receiving structure between (1) a completely closed position that obstructs the access passage and (2) an open position that at least partially exposes the access passage .
[0005] The inventor of the present invention has determined that it would be desirable to provide an improved assembly of a locking element and a receiving structure that would promptly provide the user with an indication or evidence of a previous attempt to open or tamper with the assembly.
[0006] Additionally, it would be beneficial if such an improved assembly could be relatively easy to operate, without requiring unusual complex manipulation or series of manipulations.
[0007] It would also be beneficial if the components of such an improved assembly could be relatively easy to manufacture and assemble.
[0008] Furthermore, it would be desirable if such an improved assembly could be opened without generating smaller separate waste parts. SUMMARY OF THE INVENTION
[0009] The present invention provides a combination of a locking element and a receiving structure which, together, in an initially assembled orientation, avoid, but can be subsequently operated to allow communication through the receiving structure.
[0010] The receiving structure includes (A) at least one laterally projecting shear member and (B) a nozzle that defines an access passage (that is, at least one access passage).
[0011] The closing element has an open end in which the nozzle with receiving structure extends to accommodate the relative rotation between the closing element and the receiving structure.
[0012] The locking element also includes a hole for initially receiving the shear member when the locking element and the receiving structure are in the initially assembled orientation.
[0013] The locking element also includes at least one breakable bridge that extends through a portion of the hole to be sectioned by the shear member during the relative rotation between the locking element and the receiving structure.
[0014] In a preferred mode, the nozzle also defines one of a cam and a cam follower. In this preferred embodiment, the closing element also includes a skirt that defines (1) the open end of the closing element, (2) the other between the cam and the cam follower to engage the one between the cam and the cam follower to the nozzle with receiving structure to effect the relative axial movement between the receiving structure and the closing element and (3) the hole between the open end of the closing element and the other between the cam and the cam follower.
[0015] The invention, and particularly the preferred embodiment of the invention, provides several operational advantages. The operational advantages are especially effective and desirable in the assembly components when they are molded from polyethylene and / or polypropylene.
[0016] It should be verified that the invention may include all or none of the features described above or include only one or more of the features described above or include any combination of the features described above. In addition, other advantages and features of the present invention will become readily apparent from the detailed description of the invention below, from the claims and from the accompanying drawings.

[0038] Although this invention is susceptible to modalities in different ways, this specification and the accompanying drawings reveal only a few specific modalities as examples of the invention. The invention is not intended to be limited to the modalities described in this way and the scope of the invention will be indicated in the appended claims.
[0039] To facilitate the description, many figures illustrating the invention show a currently preferred modality of a closure in the typical orientation that the closure would have when installed in the opening of a system, such as a machine, equipment or a vertical containment system ( which can be, for example, a flexible bag, bottle or other container) and terms such as top, bottom, horizontal, etc., are used with reference to that orientation. It will be understood, however, that the closure can be manufactured, stored, transported, used and sold in a different orientation than the described orientation.
[0040] The closure is suitable for use with a variety of conventional or special systems, the details of which, although not illustrated or fully described, would be evident to those who have skill in the technique and an understanding of such systems. The particular systems, per se, which are described in this document do not form part of and, therefore, are not intended to limit the broad aspects of the present invention.
[0041] The illustrated method of closure will typically be used in a system in the form of a containment system that contains a material or substance (for example, a product such as a lotion, fluent food or drinking substance) that can be dispensed or, otherwise, removed from the system through the open closure. The product can be, for example, a flowing material such as a liquid, cream, powder, slurry or paste. If the system is a container and the container and closure are large enough, then the product could also be discrete non-fluent pieces of material (for example, food products such as nuts, candies, crackers and sweets, etc.). , or non-food products including various items, particles, granules, etc.) that can be removed by opening the container by hand from a container, or pouring from a container, or pouring from a container or spilling from a container. Such materials can be, for example, a food product, a personal care product, an industrial product, a household maintenance product or other types of products. Such substances can be for internal or external use by humans or animals, or for other uses (for example, activities involving medicine, manufacturing, commercial or domestic maintenance, construction, agriculture, etc.).
[0042] One embodiment of a closure incorporating the present invention is illustrated in Figures 1 to 11B in which the closure is generally designated by reference number 20. In the illustrated embodiment, closure 20 is provided in the form of a separate closure that it is especially suitable to be attached to a system (not shown) in the form of a containment system that would typically contain contents such as a product or products consisting of articles or flowing material. Such a containment system could be a flexible folding bag or it could be a generally rigid container (which may have, in some way, flexible resilient walls), such as a bottle or tank.
[0043] The system may be some other system that may include, or be part of, for example, a medical device, processing machine, dispenser, reservoir in a machine, etc., in which the system has an opening for the system interior. The system, per se, such as a bottle, bag or other containment system, or another type of system per se, does not form a part of the broader aspects of the present invention, per se. The system can have any configuration suitable for its intended use.
[0044] If the system is a containment system such as a container, then the containment system, or a portion thereof, can be produced from a material suitable for the intended application (for example, a thin material, flexible for a bag where such material could be a polyethylene terephthalate (PET) film or a polyethylene film or a thicker, less flexible material for a bottle where such less flexible material could be an injection-molded polyethylene or polypropylene ).
[0045] In applications where the closure 20 is mounted in a container such as a bottle or pouch (not shown), it is contemplated that, typically, after the closure manufacturer makes the closure (for example, molding the components of the closure 20 from a thermoplastic polymer and assembling them together in an initially assembled orientation that defines a completely closed condition), the closure manufacturer will then send the closed closure 20 to a containment filler installation in another place where the container is manufactured or otherwise supplied and where the container is filled with a product. However, for some applications, the components of the closure 20 could be shipped by the manufacturer in an unmounted condition for the filler installation.
[0046] If the container is a foldable bag (not shown), then closure 20 may include a conventional or special accessory portion (not shown in the Figures) that can be attached to the bag as the bag is being produced and filled, or as the pouch is being produced, but before the pouch is subsequently filled through an unmounted closure base or through open regions of the pouch walls which are subsequently closed with a seal.
[0047] In the illustrated embodiment, the closure 20 is preferably provided as an assembly of a closure element 28 and receiving structure 24 that together define an article (i.e., closure 20) to be fixed to a system. The preferred embodiment illustrated by closure 20 is especially suitable as it is fixed in a non-removable manner (for example, assembled or installed) in a system that is a containment system in the form of a bag or bottle. However, it will be noted that, in some applications (not shown), it may be desirable for lock 20 to be attached to a system in a way that would allow a user to remove lock 20 from the system. In addition, it may be desirable for the closure (or at least the receiving structure of the closure) to be formed as an integral, unitary part or extension of the system (for example, a bag or bottle) in which such unitary part or extension also ( that is, simultaneously) defines an end structure (or other portion) of the system, per se.
[0048] The illustrated modality of closure 20, if initially manufactured and supplied separately from the containment system, is adapted to be subsequently attached to a containment system in an opening in the system that provides access from the external environment to the interior of the system and the contents (for example, a product contained therein) after a portion of the closure (for example, the closure element 28) is opened as described hereinafter.
[0049] When the system is a bottle (not shown), the bottle typically includes an upper end portion or other suitable structure in some part of the bottle that defines the mouth portion of the bottle (i.e., a portion that defines an opening into the bottle) and such a mouth portion of a bottle typically has a cross-sectional configuration to which the closure 20 is designed to engage. The main body portion of the bottle may have a cross-sectional configuration that differs from the cross-sectional configuration of the mouth portion of the bottle. On the other hand, the bottle may instead have a substantially uniform shape over its entire length or height without any small portion or different cross-section. The bottle can have a wall, or walls, usually rigid or flexible that can be held by the user.
[0050] The particular embodiment of closure 20 illustrated in Figures 1 to 11B is especially suitable for use with a container (not shown) that is one of a foldable, flexible bag (not shown) or a bottle (not shown) that has a wall, or walls, substantially flexible which can be compressed or deflected laterally inward by the user to increase the internal pressure inside the bottle in order to force the product out of the bottle and through the open closure. In a bottle with a flexible wall, or walls, such a flexible wall, or walls, typically have sufficient inherent resilience so that when the compressive forces are removed, the walls of the bottle return to the normal, unstressed shape.
[0051] In other applications, it may be desirable to employ a generally rigid container and pressurize the interior of the container at selected times with a piston or other pressurization system to force the product out through the open closure or to reduce the external ambient pressure of so as to suck the product out through the open closure.
[0052] On the other hand, if the lock 20 has a suitably large access passage that can be opened to communicate with the interior of the containment system through a large opening in the containment system, then such a lock can be used in a rigid or flexible containment system from which the contents (for example, the product) can be accessed through the open closure and removed by pouring out the contents, or pouring out the contents, or withdrawing the contents by hand or with an instrument, etc.
[0053] In other applications, the contents can be added to the containment system through a base or receiving structure 24 of the closure 20 before a closing element 28 is installed on the receiving structure.
[0054] In still other applications for use with a system that can be a product containment system or another type of system, the closure 20 can work to allow or prevent the egress or ingress of the ambient atmosphere or other substances in relation to the system in which lock 20 is installed.
[0055] In the illustrated embodiment, the closure 20 includes a specially configured closing body or receiving structure 24 and a closing element 28 that is adapted to be installed in and removed from the receiving structure 24. As explained hereinafter, the initial or partial opening of the closure 20 by the user will permanently change the physical condition of the closing element of the closure 28 in order to create or provide an "anti-tamper" indication for users subsequent to the initial opening or partial opening.
[0056] The closing body or receiving structure 24 and the closing element 28 are each preferably molded from a suitable thermoplastic material such as polyethylene, polypropylene or the like. In a currently preferred form of closure 20, the receiving structure 24 and the closing element 28 are each preferably separately shaped as a unitary structure from high density polyethylene (HDPE). Other materials can be used in place.
[0057] The receiving structure of the lock 24 and the locking element 28 would typically be molded separately by the manufacturer and assembled together to form the lock 20 for shipping to another location for installation in a system (for example, a containment system) such as a flexible bag (not shown) or a rigid or flexible bottle (not shown)). Figure 3 illustrates the locking element 28 prior to mounting on the receiving structure 24 shown in Figure 4.
[0058] Figure 1 illustrates the complete closure 20 with the closing element 28 installed in a condition initially closed in the receiving structure 24. Figure 1 can be distinguished by also illustrating the closing element 28 and the receiving structure 24 in an initially mounted orientation that avoids, but can subsequently be operated to allow, communication between them. Typically, in order to allow communication through closure 20, the closure element 28 is finally removed by the user from the receiving structure 28. In the preferred embodiment illustrated, the closing element 28 is unscrewed from the receiving structure 24 and raised away in order to allow sufficient access to the receiving structure 24 (the receiving structure 24 is shown in Figure 2 without the locking element 28).
[0059] Referring to Figure 2, the receiving structure 24 includes a nozzle 30 that defines an internal access passage 32 through the receiving structure 24 and that has an open distal end from which a product can be unloaded or at which a substance can be introduced. The term “nozzle” is used in this document in the sense of a high or low protuberance, which extends upwards (that is, axially outwards) or another structure that defines the access passage 32.
[0060] In the illustrated embodiment, the nozzle 30 also includes a cam 34 or cam follower 34, such as the helical thread 34 shown. The thread of the receiving structure 34 could be considered as a cam by itself or a cam follower by itself to engage a thread 70 in the locking element 28 (Figure 6) as described hereinafter. That is, if the thread of the receiving structure 34 is considered to be a cam, then the thread of the closing element 70 can be considered as a cam follower. On the other hand, if the thread of the receiving structure 34 is considered as the cam follower, then the thread of the closing element 70 can be considered as the cam. In both cases, it should be noted that the relative rotational movement between the locking element 28 and the receiving structure 24 could result from the rotation of the locking element 28 in relation to the receiving structure 24 which is kept stationary, or could result from the pivoting of the receiving structure 24 (together with the fixed system) in relation to the closing element 28 which is kept stationary or could result from the turning of both the closing element 28 and the receiving structure 24 simultaneously in opposite directions. In the preferred embodiment illustrated, thread 34 and thread 70 are each a double helical guide thread having an identical predetermined slope.
[0061] The receiving structure 24 also finally includes a laterally projecting shear member 40. In the preferred embodiment illustrated in Figure 2, there are two such laterally projecting shear members 40 located below the thread 34. The shear members 40 they can be located in or as part of the nozzle 30 or they can be located below the nozzle 30. In alternative forms (not shown), each shear member (40) could be joined to the nozzle (30) with one or more legs vertically and horizontal in order to locate the shear member (40) at a particular elevation together with the nozzle (30) above, below or adjacent to the nozzle thread (34).
[0062] Opposite the distal open end of the receiving structure access passage 32, the receiving structure 24 may include a structure suitable to be mounted in a system, such as a containment system that can be a foldable, flexible bag ( (not shown) or a bottle (not shown) or other containment system or other structure of a system to which the closure 20 is intended to be attached. For use with a foldable, flexible pouch, the bottom portion of the closure receiving frame 24 may include a suitable conventional or special accessory (for example, a “boat-shaped”, heat-sealable accessory (not shown), such as as disclosed in Patent Document No. US RE 39,520, the details of which do not form part of the broad aspects of the present invention).
[0063] If the containment system is a bag, then it is currently contemplated that most bag manufacturers will prefer to have lock 20 provided for them with a suitable accessory at the bottom end and then install lock 20 in the bag with hot sealing techniques.
[0064] If the containment system is a bottle, then it is currently contemplated that most bottlers will prefer to have closure 20 provided to them with the receiving structure of closure 24 not only including thread 34 (ie, cam 34 or cam follower 34), but also with the bottom of the lock receiving structure 24 properly configured with a quick-fit fastening feature or threaded fastening feature (the details of which do not form part of the present invention) for installation of the closure 20 on the bottle that would fit with the setting on the bottom of the receiving structure of the closure 24.
[0065] The closed closure 20 would typically be sent to a pouch or bottler manufacturer who would supply a containment system (for example, a pouch or bottle, not shown) and the pouch or bottler manufacturer would install the closure 20 in the pouch or bottle. The particular containment system (for example, bag or bottle) may have already been filled with product. Alternatively, the closure 20 can be installed in an empty containment system which is subsequently filled with product through an open bottom end of the containment system which is then sealed by sealing.
[0066] The bottom of the receiving structure of the closure 24 can readily be supplied with various fastening configuration features (not shown) suitable for a particular application - especially for a bag or bottle that has semi-rigid, resilient walls or that have walls rigid. For example, the receiving structure of the closure 24 may be provided with suitable quick-connect coupling balls (not shown) to engage complementary or bottle-fitting features (not shown) or other system. Such an engagement would resist the removal of the closure 20 by a user of the package. In an alternative arrangement (not shown), the receiving structure of closure 24 could have a lower end, rounded with a thread to thread a bottle fitting thread (not shown) or other system.
[0067] In addition, other means of providing a generally non-removable or removable fastening of the closure 20 to the container (not shown) or other system are contemplated. These other means could include the use of a suitable mechanical lock, friction welding of the lock to the system, mechanical assembly, adhesive, etc.
[0068] The access passage 32 in the nozzle 30 of the receiving structure 24 can be seen in Figure 6. The access passage 32 extends from the outer distal end of the nozzle 30 and through the rest of the receiving structure 24. The passage of access 32 communicates with an opening of the bag or bottle (not shown) or another system and the passage 32 allows material (gases, fluids, solids, etc.) to pass between the outside and the inside of the system.
[0069] It should be understood that the access passage 32 does not need to be circular as shown. The access passage 32 can be elliptical, polygonal or some other regular or irregular shape.
[0070] As can be seen in Figures 2 and 7, each shear member 40 has a leading edge 42 and a trailing edge 44. Each shear member 40 can alternatively be described as a shear fin. Preferably, each shear fin or shear member 40 is relatively smooth to accommodate intentional or accidental contact of the shear member 40 by a user's finger and / or lip.
[0071] The locking element 28 is adapted to be installed on the receiving structure 24 in an initially assembled orientation that defines an initially completely closed condition. In this condition, a combination of the locking element 28 and the receiving structure 24 together defines an initially assembled orientation that avoids, but can subsequently be operated to allow, communication through the receiving structure. The operation to allow communication through the receiving structure 24 is to unscrew the closing element 28 from the receiving structure 24, as described hereinafter.
[0072] In the preferred embodiment illustrated, the closing element 28 has a skirt 50 to engage at least a portion of the nozzle with receiving structure 30, as can be seen in Figure 6. In addition, as can be seen in Figure 6, the upper end of the closure member 50 skirt is closed by an end portion 56. As can be seen in Figure 6, the skirt 50 is defined by a generally cylindrical sleeve having a lower end portion of larger diameter.
[0073] In an alternative (but not illustrated) form of skirt 50, skirt 50 could include two generally cylindrical concentric sleeves joined at their upper ends, for example, at or near the top end portion of the closure element 56.
[0074] As can be seen in Figure 6, pending downwards from the inside of the top end portion of the closing element 56 is a seal with an internal bushing 58 which is generally cylindrical (in the preferred embodiment illustrated), but which is preferably slightly tapered (at least on the outside) in order to sealingly engage an inner end portion of the nozzle with receiving structure 30 within the open distal end of the nozzle 30.
[0075] Preferably, as can be seen in Figure 1, the locking element 28 also preferably includes tabs 62 on the outside of the locking element 28 and the tabs 62 are adapted to be engaged by a user's fingers or thumb to assist in the rotation of the locking element 28 in relation to the receiving structure 24. In the preferred embodiment illustrated, each flap 62 defines a hole 64 that minimizes the amount of material required to form each flap 62 and which can provide an additional grip feature to allow that the user's fingers and / or thumb better engage one or more of the tabs 62.
[0076] With reference to Figures 3 and 6, the bottom of the closing element 28 defines an open end (not numbered) in which the nozzle with receiving structure 30 extends to accommodate relative rotation between the closing element 28 and the structure reception number 24.
[0077] A portion of the inside of the closing element skirt 50 defines the cam 70 or a cam follower 70 which, in the preferred embodiment illustrated, is the helical thread 70 previously identified to engage the helical thread 34 to the nozzle with receiving structure 30. Thread 70 could be considered as a cam by itself or a cam follower by itself to engage the thread of the receiving frame 34. That is, if the thread of the locking element 70 is considered to be the cam, then the thread of the receiving structure 34 would be considered as the cam follower. On the other hand, if the thread of the closing element 70 is considered to be the cam follower, then the thread of the receiving structure 34 would be considered as the cam. In both cases, it should be noted that the relative rotational movement between the locking element 28 and the receiving structure 24 could result from the rotation of the locking element 28 in relation to the receiving structure 24 which is kept stationary, or could result from the rotation of the receiving structure 24 (and fixed system (for example, a bottle)) in relation to the closure element 28 which is kept stationary, or it could result from the rotation of both the closing element 28 and the receiving structure 24 (and system fixed) simultaneously in opposite directions.
[0078] In the preferred embodiment illustrated, each thread 34 and 70 is a double helical guide thread that has a predetermined inclination. The inclination is selected to provide an initial gap G1 (Figure 6A) between threads 34 and 70 when the locking element 28 and the receiving structure 24 are in the initially assembled orientation (Figures 6 and 6A).
[0079] In the preferred embodiment illustrated, the thread of the closing element 70 is defined in a portion of the upper skirt 50. Between the thread 70 and the open bottom end of the skirt 50, a lower portion of larger diameter of the skirt 50 defines two holes 74 (Figure 3) in which each extends in an arc around the skirt part 50, and the two holes 74 are each divided into smaller holes or openings by one or more breakable bridges 78.
[0080] In the preferred embodiment illustrated in Figure 3, a plurality of breakable bridges 78 extends through each hole 74 to divide each hole 74 into a plurality of smaller holes or openings that are each separated from an adjacent smaller hole or opening by one of the seven breakable bridges 74. Referring to Figure 3, there are seven of the smaller openings that are smaller circular holes, but each hole 74 also has another portion which is designated 74A in Figure 3, which is larger than each of the seven circular holes and which is generally elongated or oval in shape.
[0081] In the preferred embodiment illustrated, the lower portion of the skirt of the closing element 28 defines two elongated holes 74A located 180 ° apart. Each of the elongated orifices 74A is associated with seven smaller circular holes that, together with the elongated orifice 74A, comprise a large orifice 74 divided by seven breakable bridges 78.
[0082] Each bridge 78 that is defined between two of the smaller adjacent holes has concave sides that define a bridge structure with a narrow middle portion between the larger top and bottom end portions. This shape minimizes the effect of restricting the flow path during molding and accommodates a better filling pattern of the flow of molten plastic resin during molding in order to better fill by mold with a reduced likelihood of creating voids or cavities. This provides a wider processing window compared to the injection molding machine.
[0083] The shape of the breakable bridge 78 is easier to shape and provides greater strength even though the bridge is relatively thin at the narrowest point. This allows the designer to maximize the vertical height of the bridge. Therefore, the tapered shape leading to the narrow part of the bridge accommodates a thicker and more resistant shear member 40 in an adjacent portion of the orifice 75 when the locking element 28 is rotated in relation to the receiving structure 24, as described in detail hereinafter.
[0084] There may be less than seven circular holes that define part of hole 74 or there may be more than seven of such circular holes. That is, the number of breakable bridges 78 that extend through hole 74 to define the smallest holes may be less than seven or may be greater than seven. As seen in Figure 1, most breakable bridges 78 have opposite sides, each having a concave configuration that defines the tapered shape described above that provides the advantages described above. The shapes of the smaller holes, the oval portion 74A and the bridges 78 may differ from those illustrated and may vary.
[0085] As can be seen in Figures 3, 5 and 6, the upper skirt portion of closure element 50 that defines the helical thread cam or follower 70 is joined by at least one non-breakable connection net 94, but deformable, to the lower skirt portion 50 that defines the two holes 74. As can be seen in Figures 3 and 5, the connection network 94 defines an internal recess 96. In the preferred embodiment, there are two connection networks 94 (each with a recess 96) located about 180 ° apart. Each recess 96 is radially opened inwardly and each recess 96 extends axially so that it is axially opened at the bottom open end of skirt 50.
[0086] In the preferred embodiment illustrated, the lock receiving structure 24 has two shear members 40 spaced 180 ° away from each other and the locking element skirt 50 has two sets of multiple bridge holes 74 divided by breakable bridges 78 in smaller openings, and each of the two sets of holes 74 and breakable bridges 78 is designed to interact with an associated member between the two shear members 40, as explained hereinafter.
[0087] As can be seen in Figures 5 and 8, the lower edge of the skirt 50 has a generally circular flange 100 that has two opposite facing flat surfaces 102 that are 180 ° apart. These can be used as keys or guides to establish a desired orientation during transport and assembly of the locking element 28 with the receiving structure 24.
[0088] Initially, the receiving structure of the closure 24 and the closing element of the closure 28 are preferably molded separately or otherwise supplied as separate components. Subsequently, in a preferred process, the manufacturer assembles the two components together by making the relative axial movement between the two components so as to force the nozzle 30 of the receiving structure 24 into the skirt 50 of the closing element 28. At least a portion of at least one of the components (typically, the skirt 50 of the closure element 28) is sufficiently flexible and resilient to accommodate the insertion of the nozzle with receiving structure 30 into the open end of the closure element skirt 50 in orientation initially assembled (Figures 1, 6 and 7). In the initially assembled orientation, each shear member 40 is located so that it is received in the elongated opening portion 74A of one of the holes 74. The assembly process is carried out preferably without the relative rotation between the closing element 28 and the receiving structure 24. However, in an alternative assembly process, the two components could be threaded together and screwed in the initially assembled orientation.
[0089] After the assembly of the receiving structure 24 and the closing element 28 in the initially assembled orientation (which is the initial completely closed condition), the threaded nozzle of the receiving structure 34 does not engage with the skirt thread of the receiving element closure 70 in a manner that would effect axial movement of the closure element 28 during an initial amount of relative rotation between the receiving structure 24 and the closing element 28. Instead, the thread of the receiving structure 34 and the thread of the closure element 70 has a predetermined, identical slope and is initially separated by a predetermined gap G1 (Figure 6A) so that the initial rotation of the closure element 28 in the opening direction (indicated by arrow 108 in Figure 6A) with respect to receiving structure 24 will not initially cause an axial upward movement of the locking element 28 due to the gap G1. The way in which the parts interact during the initial turn can be explained more specifically with reference to Figures 6A, 8A, 9A and 11A, in which the lower thread portion of the closing element 70 is shown in cross section on the right side in each Figure e is designated 70A and the lower portion of the thread of the receiving element 34 is shown in cross section on the right side of each Figure and is designated 34A. With particular reference to Figure 6A, the thread portion 70 designated as 70A in Figure 6 will be rotated behind the plane of the view in Figure 6A and will not engage the cam surface facing upwards of the thread portion of the receiving structure 34A until the locking element 28 has been rotated about 100 ° from the position shown in Figure 6A. Therefore, the first approximately 100 ° of rotation of the closing element 28 with respect to the receiving structure 24 does not immediately engage the thread of the closing element 70 with the thread of the receiving structure 34 in a way that would cause axial translation (i.e. i.e., axial movement) of the closing element 28.
[0090] The continued rotation of the closing element 28 in the opposite direction to the initially mounted orientation shown in Figures 1 and 6A will cause the gap between the thread of the closing element 34 / 34A and the thread of the receiving structure 70 / 70A for a smaller span G2, as can be seen in Figure 8A for the cross-sectional portion of the threads designated as 34A and 70A in Figure 8A. The additional rotation of the closing element 28 reduces the gap additionally, as can be seen in Figure 9A where the reduced gap is indicated by G3. After about 100 ° of rotation of the closing element 28 in relation to the receiving structure 24, as shown in Figure 10A, it can be seen that the cross-sectional portion of the thread of the closing element 70A came into contact with the section in section transverse thread of the receiving structure 34A and the span went to zero, as indicated in G4. The arrangement of threads 34 and 70 with an initial gap G1 between the threads can be designed in a conventional manner by a person of ordinary skill in the art.
[0091] In view of the initial threaded span arrangement, if a user tries to open the locking element 28 by turning the locking element 28 in a counterclockwise direction, as indicated by arrows 108 in Figure 7, then the locking element closure 28 will initially rotate about the vertical geometric axis, but will not initially axially move outward, upward and along the nozzle with receiving frame 30. The thread of the receiving frame 34 and the thread of the closing element 70 are configured with the initial span G1 so that they do not affect the relative axial movement between the receiving structure 24 and the locking element 28 until the relative rotation has occurred by a predetermined rotation angle (for example, about 100 °). Only after a sufficient amount of initial relative rotation, do the threads 34 and 70 cooperate to cause the locking element 28 to move axially upwards (outwards) along the nozzle of the closing receiving structure 30.
[0092] The amount of rotation required before the locking element 28 is axially moved in relation to the receiving structure 24 can be greater or less than 100 °, depending on the particular designs of the skirt holes 74 and various other closing features 20.
[0093] In the orientation initially assembled and illustrated in Figures 1, 6 and 7, each shear member 40 projects outwards and inwards, and preferably partially through one of the associated closing element skirt holes 74 and , in particular, partially through the elongated portion 74A of the orifice 74 which is initially divided by the plurality of breakable bridges 78. As the relative rotation is carried out between the locking element 28 and the receiving structure 24, typically by a user who holds and rotates the locking element 28 in the counterclockwise direction indicated by arrows 108 (Figures 7 and 8), breakable bridges 78 move sequentially against the leading edge 42 of the associated shear member 40 and are sectioned by the shear member 40. Figure 8 illustrates the relative positions of the receiving structure 24 and locking element 28 after some amount of initial relative rotation between the two components and in Figure 8 can be seen the shear members 40 have sectioned a number of breakable bridges (whose sectioned ends are designated 78A in Figure 8).
[0094] As the user continues to rotate the locking element 28 in a counterclockwise direction as indicated by the arrows 108 in Figure 8, the locking element thread 70 and the receiving frame thread 34 are not yet effective in causing the axial movement of the locking element 28 until a predetermined amount of rotation has occurred (for example, about 100 °) as previously explained, therefore, the locking element 28 only rotates initially, but does not initially move axially upwards in relation to the receiving structure 24. The user continues to rotate the locking element 28 so that the projecting shear members 40 each sequentially section the associated breakable bridges 78. After the last breakable bridge 78 has been sectioned, as shown in Figures 9, 9A and 9B, the front end 42 of each laterally projecting shear member 40 begins to engage the part of the connection network 94 between the last shear breakable bridge 78 / 78A and the beginning of the elongated opening portion 74A of the other orifice 74. This engagement of the skirt 94 connection nets with the shear members 40 can cause the lower skirt portion 50 to deform radially outward (at least temporarily) in opposite directions as indicated by arrows 120 in Figures 9A and 9B. This causes a radial distortion (which may be temporary or permanent) in the lower portion of the closing element of the skirt 50 (especially in connection nets 94) and this radial distortion is readily apparent to the user as the user continues to rotate the closing 28 in the opening direction (indicated by the rotating arrows 108 in Figures 9, 9A and 9B).
[0095] In some applications, it may be desired that the radial distortion and deformation of the lower skirt portion 50 are only elastic and temporary. In other applications, it may be desired to provide a design in which at least some amount of the radial distortion and deformation of the locking element 28 is a permanent, inelastic deformation. Although permanent radial deformation and distortion of the bottom of skirt 50 of closure element 28 may be desirable in some embodiments of the invention and although such permanent distortion may provide evidence of the opening of, or, ultimately, an attempt to open, the closing 20, it is not a necessary requirement or essential resource of the broad aspects of the present invention that the radial deformation is permanent (or that it is temporary).
[0096] During the opening process, as the closing element 28 is rotated (in the direction of opening indicated by the arrows 108) and as the breakable bridges 78 are sectioned by the shear members 40, the sectioning of each breakable bridge 78 generates preferentially an audible click. As breakable bridges 78 are sequentially sectioned, audible clicks may sound, in some way, like the noise created when a conventional zipper is opened or closed. The user can confirm by the sound that breakable bridges 78 are being sectioned. Of course, the user can also visually observe the sectioning of breakable bridges 78. Depending on the material from which the locking element 28 is molded and depending on the particular thickness and / or shape of each breakable bridge 78, the sound generated by the sectioning of bridges each breakable bridge 78 can be more or less audible to the user. According to the broad aspects of the present invention, although it is preferable to generate a sound that is particularly audible to the user, this is not a necessary requirement or essential feature of the broad aspects of the invention.
[0097] As breakable bridges 78 are sectioned, whether a sound is heard by the user or not, sectioning each breakable bridge 78 can also provide a discrete tactile response so that a relatively rapid rotation of the closing element 28 through a first rotation angle (for example, 100 °) may result in a generally continuous vibration sensation or response that is felt by the user opening the lock. According to the broad aspects of the invention, such a discernible tactile response, while preferred, is not a required or essential feature of the broad aspects of the invention.
[0098] As each shear member 40 begins to engage and deform outwardly the lower skirt portion 50 of the closure element 28, the thread of the receiving structure 34 and the thread of the closure element 70 begin to come into contact in one cam coupling that exerts an axial force on the locking element 28 which tends to urge the locking element 28 axially upwards with respect to the receiving structure 24 towards the position shown in Figures 10, 10A and 10B. However, the locking element 28 is not initially free to move upwards relative to the receiving structure 24, as can be seen in Figures 9, 9A and 9B, due to the fact that a portion of each shear member 40 is still stays within the associated orifice 74 - thereby avoiding the upward movement of the skirt portion 50 below the orifices 74. Therefore, the closing element skirt 50 becomes subject to axial tension and begins to stretch very discreetly - preferably within the elastic band of the material.
[0099] The continued rotation of the locking element 28 from the position shown in Figures 9, 9A and 9B tends to propel the locking element 28 axially towards the position shown in Figures 10, 10A and 10B while causing the recesses of the closing element 96 (Figures 9B and 10B) move adjacent to the shear members 40 and each recess 96 in the deformed connection network 94 accommodates the larger radial dimension of each shear member 40. As can be seen in Figures 9B and 10B , each shear member 40 is tapered laterally so that it narrows towards its rear end 44. The decreasing radial extent of each shear member 40 towards its rear end 44 is such that, after sufficient rotation of the shear member closure 28 in the opening direction, each shear member 40 no longer protrudes into the closure element orifice skirt 74 and is no longer effective in positively resisting upward force if not exerted by the lower skirt portion 50. When the shear members 40 no longer protrude into the skirt holes 74, the skirt of the locking element 50 which has been elastically tensioned in the axial direction, is now available to overcome any frictional engagement existing with the shear members 40 and can bounce up slightly (in the direction of the arrows 130 in Figures 10A and 11A) and this causes the lower edges of the skirt holes 74 to move beyond each shear member 40, as can be seen in Figures 10A and 11A.
[00100] In the preferred embodiment illustrated in Figures 1 to 11B, the action of a lower skirt portion 50 jumping upwards in relation to each shear member 40 is preferably accompanied by a physical sensation that is felt by the user when the user rotates the locking element 28 for the open condition. The user may feel that the closing element 28 is "jumping up" or "popping" or "popping" in relation to the receiving structure 24. This sudden movement of the closing element 28 in the upward direction is preferred, in order to provide the user with an additional indication of the combination of the opening process, but such a feature is not a required or essential feature of the broad aspects of the invention.
[00101] Referring to Figures 10 and 10A, 11 and 11A, as the user continues to rotate the locking element 28, each connection network 94 that defines the recess 96 preferably remains outwardly distorted in the directions of the arrows 120, but not is torn or sectioned. Therefore, the lower skirt portion 50 below the openings 74 remains connected (secured) to the skirt portion 50 above the holes 74 even though all breakable bridges 78 have been sectioned. Therefore, as can be seen in Figure 11A, the portion of the skirt 50 that was radially deformed in the direction of the arrows 120 can now be pulled upwards along with the rest of the closing element 28 by the action of the thread of the closing element 70 in engagement. cam with the thread 34 of the receiving structure 24. And, by the additional rotation of the closing element 28, the closing element 28 is moved axially (ie, translated) additionally upwards and along the nozzle 30. Eventually, the threads 34 and 70 become disengaged and the entire locking element 28 can be lifted upwards out of the receiving structure 24 to open the lock 20.
[00102] It will be seen that the rear edge 44 of each shear member 40 is adapted to guide the closure member 50 skirt as it rises and surrounds the shear members 40 during the axially relative upward movement of the closure member 28 as the locking element 28 is being rotated by the user.
[00103] In addition, the rear edge 44 of each shear member 40 can function to help guide the locking element 28 through the shearing members 40 when the manufacturer initially installs the locking element 28 on the receiving structure 24.
[00104] The process of assembling the locking element 28 and the receiving structure 24 by the manufacturer could include the manufacturer merely pushing the locking element 28 downwards into the receiving structure 24 while both components are in rotating alignment suitable for the initially assembled (closed) orientation (Figures 1 to 7) and the flexibility of the components, especially the flexibility of the locking element 28 would accommodate such an installation.
[00105] In another possible method of assembling the lock 20, the locking element 28 could also be rotated as it is being pushed down on the receiving structure 24 in order to engage the thread of the receiving structure 34 with the thread of the closing element 70 with the rotation being terminated at the point where the azimuthal (i.e., rotating) alignment between the two components corresponds to the completely closed orientation assembled initially (Figures 1 to 7).
[00106] It will be appreciated that the combination of the locking element 28 and the receiving structure 24 of the present invention can be designed to provide one or more different types of indications that the locking element 28 has been previously opened or at least one An attempt was made to open the locking element 28.
[00107] It will also be noted that when the preferred mode of the locking element 28 is initially removed by the user from the receiving structure 24, the breakable bridges of the locking element 78 are sectioned and the lower end of the locking element can remain (and remains preferably) radially distorted, but the closure element 28 also remains a unitary structure without any separate detachable parts or strips being generated by the opening process. As a result, there are no small pieces separated from the closure element 28 that could present a risk of suffocation for children or that would have to be recovered separately and retained for disposal. However, the structural and operational features of the preferred mode of closure 20 that prevent the formation of smaller, separate, discrete disposal parts are not an essential requirement of the broad aspects of the invention.
[00108] In some applications, it may be desirable to design the locking element 28 so that after the locking element 28 has been opened and removed from the receiving structure 24, some small amount of distortion or radial deformation outwards remains over. from the lower edge of the skirt 50 which defines a somewhat elongated or oval shape (as seen in plan from above or below). In other applications, it may be desired to have a permanent deformation and it may be desired, instead, to design the closure member skirt 50 so that it generally remains in an original attractive shape, not deformed.
[00109] It will be noted that the number of breakable bridges 78 and the openings defined between breakable bridges 78 may vary. In the preferred embodiment illustrated in Figures 1 to 11B, breakable bridges 78 are provided in two sets or groups, with each group being adapted to be sectioned by one of the two shear members 40. However, breakable bridges 78 could be arranged in just one group or could be arranged in more than two groups. The number of breakable bridges 78 could vary from one to two or more. In addition, although all breakable bridges 78 have the same shape in the preferred embodiment, each breakable bridge 78 could have a shape that differs from the shapes of other breakable bridges.
[00110] In an alternative form of skirt 50 (not shown), skirt 50 could include two generally cylindrical concentric sleeves joined at the upper ends, for example, at or near the top end portion of the closure element 56.
[00111] Furthermore, in such an alternative embodiment, the holes 74 could be located further up in the outer concentric sleeve of the skirt 50, for example, close to the top end portion 56 of the closure element 28 above or adjacent to the threads 70 In such an alternative arrangement, each shear member 40 could be joined to the receiving structure 24 below the inner concentric sleeve of the skirt with an L-shaped support member that has a vertical leg extending upward between the inner and outer mandrels. to locate the shear member in the elevated orifice 78.
[00112] Referring to Figure 6, the preferred embodiment of the closure element 28 is illustrated as having an end portion 56 which, in combination with the other elements of the closure 20, prevents communication between the exterior environment and the interior of the closure 20 when lock 20 is closed. However, the present invention indicates that the closure member 28 could be modified to, among other things, include a dispensing hole (not shown) in the end portion 56 and to include annular sealing features (not shown) in both the closure element 28 and the receiving structure 24 so that when the closing element 28 is moved axially upwards relative to the receiving structure 24, then such sealing features would work to prevent fluid leakage and accommodate the dispensing of a flowable material from the inside of such a modified closure through such a dispensing orifice at the top of the closure element 28 and towards the outside environment. Such closing element dispensing orifice and such annular sealing features in the closing element and the receiving structure are well known and are disclosed, for example, in U.S. Patent Documents No. 3,887,116; 5,680,969; 6,095,382; 6,290,108; 6,446,844; 6,513,681 and 6,739,781.
[00113] In yet another embodiment (not shown), the thread of the receiving structure 34 and the thread of the locking element 70 could all be eliminated. In such an embodiment, the user would rotate the locking element 28 to section the breakable bridges 78 and to position each recess of the locking element 96 and connecting network 94 adjacent and laterally deformed by a shear member 40. Then, the user would have to pull the locking element 28 to lift it out of the receiving structure 24.
