    System and method for screw-on tamper-resistant closures
    Claiming priority
    This filing claims the precedence of the provisional U.S. Patent Application Serial No. 62 / 332,979, filed May 6, 2016, disclosure of which is incorporated by reference in this document.
    Technical area
    This disclosure generally relates to container closures and, in particular, but not limited to, a pre-tapped closure with a tamper-resistant tape screwed onto a threaded bottle.
    Background
    It is known to use threaded closures to close and seal beverage bottles. The closures have multiple functions. The closure provides the seal to hold the beverage in the container. In addition, the closure serves to keep the beverage fresh, to keep oxygen from the beverage, and to keep carbon dioxide, in the form of carbonation, in the beverage. Once the closure is removed by the
    BE2017 / 5315 consumer, if it is a threaded closure, it can be replaced. It is important that this type of closure has features that demonstrate that the closure has been removed. U.S. Patent No. 2,367,317 to John
    W. Thomas, filed July 4, 1942, entitled "Closure", which is incorporated herein by reference, discloses an aluminum threaded closure with a crimped tamper-resistant tape. The closure can be closed again with the screw thread. When the closure is twisted off the screw thread of the bottle, the twist action breaks pre-formed bridges in the closure and separates a cap portion of the closure from the tamper-resistant strap, which may also be referred to as a pilfer-proof strap. The closure is unscrewed and removed from the holder, but the pilferproof / tamper-resistant strap remains crimped or otherwise attached to the holder.
    Thus, if a consumer receives a bottle whose cap portion of the closure has already broken away from the tamper-resistant strap, the consumer will know that the bottle has been tampered with and that this potentially pilfer-proof feature indicates to the consumer that it is not safe for consumption. In this way it provides
    BE2017 / 5315 closure has been made by the filler after filling the bottle, and that the bottle has remained closed until opened by the consumer.
    Another example of a tamper-resistant feature of conventional threaded fasteners is described in U.S. Patent 5,891,380 to LaRue, which is incorporated herein by reference. This closure includes vertical slots placed around a bottom portion of the skirt and which open during the first removal of the closure. The vertically slotted band is removed with the closure, but if it is re-threaded to the holder, the open-ended configuration of the vertically slotted band indicates to the consumer that the closure has been previously removed.
    Conventional metal closures are often referred to as roll-on pilfer-proof ('ROPP') closures. ROPP refers to the tamper-resistant strap and also refers to how the closure is applied to the holder. The closure is rolled up. This refers to the action of applying an axial force to hold the closure on the holder and using form rollers that rotate around the closure and form the skirt portion to fit the threads of
    BE2017 / 5315 the holder. The holder can be in glass, plastic, or aluminum. A second set of form rollers rolls the tamper-resistant tape onto the container.
    Winemakers sometimes close wine bottles with threaded closures. Since wine thread closures have historically shown low quality, winemakers need a thread closure, but the closing threads are not visible until the closure is removed.
    U.S. Patent No. 7,922,018 to Jacques
    Granger et al., Filed December 21, 2005, entitled "Bottle Closure with Improved
    Thread, which is incorporated by reference in this document, discloses a closure with an injection molded plastic insert in a metal dummy.
    The plastic insert contains the thread to screw the closure onto a pre-tapped bottle. The outer metal dummy has two functions, firstly it provides a clean, wire-free look for the closure. Second, the outer metal dummy includes the tamper-resistant ring or band crimped onto the container. This closure is applied to a pre-tapped bottle by screwing the plastic wire from the grip and screwing the closure to the wire. Then, leave insert in the glass thread of the bottle
    BE2017 / 5315, the tamper-resistant ring is rolled or crimped onto the bottle. U.S. Patent No. 8,231,019 to Piero Battegazzore, filed March 25, 2008 and entitled "Bottle Closure", which is incorporated by reference herein, discloses a similar closure in which a metal dummy contains a plastic threaded insert.
    Beverage companies, such as breweries, use bottle-shaped aluminum containers, also known as bottle holders, to package their products. Aluminum bottle-shaped containers are formed by drawing and ironing an aluminum disc in an elongated cylindrical dummy. The dummy undergoes further shaping operations to create the shoulder, neck and container finish.
    A thread is formed in the end portion of the bottle.
    In addition, a curl is formed to provide a safe surface for the consumer to drink directly from the bottle-shaped container. An aluminum closure is applied to the bottle-shaped container using the roll-on pilfer-proof process described above.
    By reducing the amount of aluminum used in the containers without reducing the action of the bottle-shaped containers to bottle-shaped containers, packaging costs can be significantly
    BE2017 / 5315, while retaining the image to which consumers have become accustomed. The bottle-shaped containers must be able to withstand significant axial loads to receive a rollon pilfer-proof closure. U.S. Patent Application Publication No. 2015/0344166 to Daniel Davis et al., Filed May 30, 2014, entitled "Low Spread Metal Elongated Bottle Production and Method", which is incorporated by reference herein, discloses an aluminum bottle-shaped container and a method of forming the bottle-shaped container.
    Summary
    A method of attaching a tamper-resistant closure to a container comprises providing a pre-tapped closure defined by an upper portion and a skirt portion protruding from the upper portion. The skirt portion defines an inner closure thread surface and an opposing outer closure thread surface of at least one closure thread. The skirt section also includes a tamper-resistant band. The pre-tapped closure is rotated to engage the at least one closure wire in at least one container holding wire. The inner sealing wire surface is in
    BE2017 / 5315 contact with a surface of the at least one holder wire. The tamper-evident strap of the pre-tapped closure is rolled to attach the tamper-resistant strap to the container.
    Technical advantages of closing a bottle-shaped container with a tapped closure according to the teachings of the present specification include a decrease in the axial force required to close the bottle-shaped container. By decreasing this axial force, the bottle-shaped container can be formed less robust than conventional glass or metal bottles because it has to withstand less axial force without deformation. Raw materials for manufacturing such bottle-shaped containers can be less expensive, providing cost savings to the bottle manufacturer.
    Other aspects, features, and advantages will become apparent from the following detailed description taken in conjunction with the accompanying drawings, which form part of this description and illustrate, by way of example, the principles of the disclosed inventions.

    Detailed description
    Reference is made to Figure 1, a perspective view of a dummy 10 according to the teachings of the present specification. The dummy 10 can be made of any suitable metal, such as a rigid metal such as steel, or it can be made of a softer metal such as aluminum. In an alternative embodiment, the dummy 10 may be made of plastic and formed by known polymeric molding processes, such as injection molding. The dummy 10 is generally textured without structure and includes an upper portion 12 and a cylindrical skirt portion 14 protruding from the upper portion 12. The top portion may include a chamfer 13 in transition to the skirt portion 14. The dummy 10 is formed by a generally flat metal disc, such as aluminum, in the form of the dummy 10. The dummy 10 undergoes additional shaping operations around a pre-tapped closure attached to and sealing a threaded receptacle.
    BE2017 / 5315
    Reference is made to Figure 2, a perspective view of a pre-tapped closure 20 according to the teachings of the present specification. The pre-tapped closure 20 includes a cap portion 22 and a tamper-resistant tape 24 positioned under the cap portion 22. The closure 20 is pre-tapped. That is, a spiral wire 26 is formed in the skirt portion 14 for attaching the pre-tapped closure 20 to a threaded container. The cap portion 22 includes the top portion 12, the coil 29, and a coil wire 26.
    The tamper-resistant band 24 is formed from a lower portion of the skirt. A frangible portion of the skirt 14 is created by interrupted slots 30 made in the skirt 14. Bridges 32 of metal, for example aluminum, connecting the tamper-resistant tape 24 to the cap portion 22 are placed between the slots 30. Slots 30 are formed by a molding machine, as discussed below. According to certain embodiments, a single forming machine can form the slots 30, the coil 29, and the coil wire 26. When the closure 20 leaves the molding machine, it is ready to be placed on a threaded container
    BE2017 / 5315 are screwed like a bottle-shaped aluminum holder, which can also be referred to as a bottle holder.
    The spiral wire 26, or multiple wires, is formed in the skirt portion 14 above the tamper-resistant tape 24. The wire 26 is formed using one of several metal forming processes and tools that shape the metal to contour in the shape of the spiral wire 26. Since the wire 26 is formed by metal forming processes applied to a thin metal (ie aluminum) dummy, for example an aluminum dummy, the spiral wire 26 includes an outer wire surface 27 and an opposite inner wire surface 28 (see Figure 4). The inner thread surface 28 is indented with respect to the rest of the skirt portion 14, and the outer thread surface 27 is in the form of a projection with respect to the rest of the skirt portion 14.
    In one embodiment, to form the coil wire 26, a mandrel receives the dummy 10. The mandrel is formed of a hard material and includes the negative of the features desirable to be formed on the dummy 10. A punch or other forming device exerts forces on the dummy 10 sufficient to hold the metal of it
    BE2017 / 5315 skirt section 14 in the form of the negative of the thread of the mandrel. In certain embodiments, the mandrel rotates so that shaping can take place over the entire perimeter of the dummy. In other embodiments, the mandrel is stationary, and the punch or other molding device rotates to form the full circumference of the dummy 10. In still other embodiments, both the mandrel and the molding device rotate to form the features of the closure. 20.
    After forming the screw thread 26, the dummy 10 is removed from the mandrel. In one embodiment, the mandrel rotates in the opposite direction of the forming direction to loosen the formed threads 26 of the dummy 10 from the threads of the mandrel. According to an alternative embodiment, a belt uses friction between the outer surface of the dummy 10 and the belt surface to rotate the dummy to loosen the thread 26 from the mandrel.
    According to an alternative embodiment, the wire 26 is formed in the skirt portion 14 using tools other than a mandrel. Thus, an outer surface of the skirt portion 14 is machined by a forming tool, which
    BE2017 / 5315 forms the metal (i.e. aluminum) in the thread 26. In the forming method, the dummy 10 can move or rotate and the tool is stationary, or alternatively, the dummy 10 is stationary and the tool moves. According to yet a further alternative embodiment, one mold disc within the dummy 10 can be received and a second mold disc engages the outer surface of the dummy 10. The discs rotate in opposite directions to form the metal to form the screw thread 26. alternatively, the dummy can rotate 10 and the two opposing shape disc tools can remain stationary. By disconnecting the two shaping discs, the formed dummy is released from the tool, the dummy, now with the
    screw thread 26, can continue are being formed or otherwise processed.According to particular embodiments, is the screw thread 26 a continuous spiral wire That along it
    skirt portion 14 snakes down. Thus, the coil wire 26 can extend about 2 1/2 times around the circumference of the skirt portion 14. Thus, to turn the closure 20 on or off, the closure 20 must make 2.5 turns relative to the threaded container . In other embodiments,
    The thread 26 consists of a number of short threads or thread attachments which may or may not wind down along the skirt portion 14. The different threads can allow the cap or closure 20 to be removed from the bottle with
    less revolutions from the closure than with some continuous thread. So, can in a series from four wires each wire about a quarter from the outline of it
    skirt portion 14 extend such that a quarter rotation or turn of the closure 20 relative to the threaded container will cause the threads of the closure to engage or
    loosen from the corresponding wires of the holder the closure 20 On the wire holder or of it to remove. In this respect, the closure with multiple
    threads function similarly to a crown type closure known in the art.
    A serration 29 is also formed by deforming an upper portion of the skirt portion 14 near the intersection of the skirt 14 and the upper portion 12. The serration 29 is deformed metal in a pattern to provide a characteristic that gripping the closure 20 is facilitated so that a consumer can more easily grip and rotate the closure 20. The cartel 29
    BE2017 / 5315 can also facilitate gripping of the closure 20 for a closure head or other machines associated with the process of closing a filled container or further metal formation of the closure 20. Knurling and slots of the closure 20 can be performed by a cartel available from SACMI or Imola, Italy. An example of a knurling and slitting machine for forming the knurling 29 and the tamper-resistant strap 24 for closures, such as closure 20, is described in Danilo Albonetti's U.S. Patent 7,673,543, filed December 27, 2004, and entitled "Apparatus for Making a Fracture Cut Between the Cup and the Safety Ring in Plastic Caps, 'which is incorporated by reference in this document.
    Attention is given to Figure 4, illustrating the features inherent in the pre-tapped closure 20. A liner 34 is attached to a bottom surface 36 of the top portion 12. According to one embodiment, the liner 34 is attached to the bottom surface 36 after certain features under which slots 30 and knurling 29 are formed. This can protect the liner 34 from damage during these forming operations. According to an embodiment, the coating 34 can be formed and
    BE2017 / 5315 applied to the closure using a specially designed machine available from SACMI or Imola, Italy. An example of a coating machine for coating coatings, such as closure 20, is disclosed in U.S. Patent No. 6,718,606 to Giovanni Bassi, filed September 6, 2002, entitled "Apparatus for Molding and Applying Liners in Caps", which is incorporated by reference in this document. The liner 34 is cast in the dummy on a bottom surface 36 of the upper portion 12, as discussed in more detail below. In an alternative embodiment, a preformed disc coating may be inserted into the closure 20 and held in the closure 20 by a coating attachment ring formed in the closure 20 prior to insertion of the disc coating.
    In certain embodiments, the liner 34 may also have an oxygen-reducing function by absorbing oxygen that arises in the container's main space and at least partially penetrates the liner where it can be absorbed by an oxygen separator, such as sodium sulfite.
    BE2017 / 5315
    Reference is made to Figure 3, which illustrates a step in a sealing process in which the pre-tapped closure 20 is attached to a container 38, for example, a bottle-shaped aluminum container. Figure 3 illustrates a portion of a sealing machine head 42 and an upper portion of the container 38 which includes a neck portion 49 and an end portion 50. The end portion 50 includes a mounting ring 52 receiving the tamper-resistant strap 24, a male retainer wire 48, and a curl 54 attached to a mouth of the container 38. A sealing machine may include multiple heads, and a filling and closing operation may utilize of multiple sealing machines. The sealing machine may be one supplied by Zalkin or Montreuil l'Argillé, France, a subsidiary of Pro Mach of Covington, Kentucky. According to certain embodiments, the sealing machine includes one or more Zalkin model VS100 or VS110 closing heads. The closure head 42 is specially designed to screw on the pre-tapped closure 20 and follow the screwing operation by crimping or rolling the tamper-resistant tape 24 on the holder 38.
    The tapped closure 20 is received by the clamp 44 of a star wheel. After the tapped closure is 20
    BE2017 / 5315, the head 42 of the sealing machine, together with the clamp 44 holding the pre-tapped closure 20, is lowered onto the holder 38. According to an alternative embodiment, the closure 20 can be placed, but not screwed, onto the holder upstream of the sealing machine 40. According to either embodiment, the clamp 44 and the closure 20 rotate about the female threads of the pre-tapped closure 20. causing the male wires 48 of the container to grip. Together with the rotation of the clamp 44, one or more shrink disks, also called rollers, 46 also rotate along with the clamp 44. Once the clamp 44 has performed the number of revolutions, for example 2 1/2, to apply sufficient clamping force to secure the closure 20, more particularly the liner 34 to the container, the clamp 44 stops the closure 20 from rotating. This can be accomplished by the clamp 44 releasing the grip on the closure 20 or the rotation of the terminal 44 stops. The head 42 continues to rotate and the discs or rollers 46 are directed radially inward to apply a radial force to shrink or roll the tamper-resistant tape 24 on the holder 38. More specifically, the tamper-resistant tape 24 is crimped or rolled onto a mounting ring 52 formed
    BE2017 / 5315 in the neck 49 of the holder 38 under the holder wire 48. According to an embodiment, the mounting ring 52 is an indentation around the circumference of the neck 49 of the holder.
    Screwing onto the pre-tapped closure, that is, rotating the closure 20 to engage the closure wire 26 in the holder wire 48 requires less axial force on the holder 38 than a conventional roll-on application where the closure wire is formed together by applying the closure to the container. For the roll-on application, a force must be applied to the container combination closures sufficient to make the seal between the liner and a sealing surface of the container curl and maintain that seal while the rollers form the skirt portion to form the thread. to shape.
    This roll-on thread-forming operation is not required when screwing on the pre-tapped closure 20 according to the teachings of the present specification. Accordingly, the screw-on process can reduce the axial load applied to the closure 20 and container 38 to create a suitable seal between the liner 34 and a sealing surface 53 of the curl 54 of the container 38 to about 130 pounds or less. Thus, axial forces can be in the range of 10BE2017 / 5315
    140 pounds create a suitable seal for closing a bottle-shaped aluminum container filled with a carbonated beverage, such as beer.
    According to one embodiment, an axial force in the range of
    4060 pounds create a suitable seal for a carbonated beverage container when used with the described screw cap closure process.
    Closing according to the teachings of the present disclosure represents a significant decrease in the 260 to 275 pounds of axial force required to create the coating / mouth seal for the conventional roll-on process. As described below, this drop in axial force may allow certain parts of a bottle-shaped aluminum container to be formed from less aluminum because certain parts of the container need not be as strong as the container must withstand less axial force during the screw cap closing process. the pre-tapped closure 20. In particular, this drop in axial force allows the use of bottle containers with an axial compression resistance to deformation less than 275 pounds.
    against deformation less than 260 pounds.
    According to certain embodiments, the axial pressure is resistance
    BE2017 / 5315
    Reference is made to Figure 4, which shows the closure 20 threadedly attached to the container 38 with portions removed and shown in cross-section. The
    tamper resistant band 24 is becoming crimped on the mounting ring 52 That in the holder 38 is formed. Compression of the coating 34, who is formed from
    resilient material, creates a seal between the pre-tapped closure 20 and a sealing surface 53 of the curl 54 of the holder 38. In certain embodiments, the holder 38 may be a metal, for example, aluminum, bottle-shaped holder, and the curl 54 may be a rolled flange . According to alternative embodiments, the container 38 may be glass or plastic. The seal prevents the beverage from leaking from the container 38 and also retains the carbonation, the CO2, when the container is filled with a carbonated beverage, such as beer.
    A reforming portion 56 of the pre-tapped closure 20 creates additional compression of the liner 34 in a generally radial direction on top of the axial compression of the liner 34. Grasping the coil wire 26 of the pre-tapped closure 20 presses the liner axially and radially together to create the seal. The reform part 56
    BE2017 / 5315 is formed using tools in combination with the other metal forming operations performed on the dummy 10, such as knurling, thereby forming the slots 30 and / or forming the wire 26. The reformer portion 56 allows the liner 34 to seal a carbonated beverage, placing the container and the seal under an outward pressure. The reforming portion 56 can be omitted when the preformed closure 20 is used to seal a container filled with a non-carbonated beverage, i.e., a beverage that has not been carbonated, such as flat water.
    In certain embodiments, the liner 34 may also include an oxygen separator to reduce the oxygen level present in the main space of the container 38. The oxygen-separating coating may also absorb oxygen from outside the container to prevent oxygen from entering the container. An example of a suitable oxygen-secreting coating is described by U.S. Patent 9,248,943, filed February 18, 2013, and entitled "Container Closure", which is incorporated by reference herein. The seal between the
    BE2017 / 5315 cover 34 and the sealing surface 53 of the curl 54 is held by gripping the female thread 26 of
    the closure 20 in the male thread 48 of the container 38.Figure 5 illustrates a side view from the bottle-shaped holder 38 with the closure 20 die On the
    bottle-shaped container 38 is threaded according to the teachings of the present specification and forms a seal between the liner 34 and the sealing surface 53 of the curl 54 of the container 38 (see Figure 4). The container 38 can be formed from any suitable material. According to certain embodiments, the container 38 is formed of aluminum which has been drawn, stretched and further formed in the bottle-shaped configuration, shown in Figure 5. An example of a bottle-shaped container formed of aluminum is described in U.S. Patent Publication No. 2015/0344166, filed 30 May 2014 and titled "Low Spread Metal Elongated Bottle and Production Method," which is incorporated by reference in this document.
    According to certain embodiments, the neck portion 49, which includes a shoulder portion 62, a tapered profile 64, and the end portion 50 (see Figure 4), may have less aluminum to form those parts of the
    BE2017 / 5315 holder 38 then in a conventional aluminum bottle-shaped holder. Other parts of the container including the cylindrical portion and the dome portion 59 may not experience a drop in the amount of aluminum to form these parts. The lower amount of aluminum in certain parts of the container 38 is possible by screwing the pre-tapped closure 20 onto the wire 48 of the container 38 to form the seal between the liner 34 and the sealing surface 53 of the curl 54 of the container 38, which is achieved with less axial force than conventional roll-on closing. Thus, the screw-on seal can be realized with 130 pounds or less of force. In one embodiment, the aluminum bottle-shaped container 38 may have 8% 50% less aluminum in the upper third of the container 38 when the closure is applied by the screw-on process, as opposed to the wind-up process.
    According to an alternative embodiment for a lightweight container with less aluminum in certain parts, the container 38 may comprise a neck ring. A neck ring is an annular structure that protrudes radially from the neck portion 49 near the end portion 50. When closing, either using the conventional roll-on
    BE2017 / 5315 closing process or the closing process with screw cap described herein, the closing head receives the neck ring during the closing process.
    With the neck ring received by the closure head, the neck ring resists the axial force of the closure head as opposed to the situation where the entire container 38 resists the closure force. Larger axial loads can be used to close a container with a neck ring than to close a container without a neck ring, because the neck ring resists the higher axial loads that would otherwise be particularly useful on a condition or otherwise. the same axial against which a glass container can cause the container to wobble. A neck ring can be aluminum holder that is not withstand loads like tooth. An example of a process of closing plastic bottles with a neck ring is described in U.S. Patent 7,552,575 to Wendell S. Martin, which is incorporated by reference herein.
    Reference is made to Figure 6, which is a flow chart of a process 100 of closing a filled beverage container by screwing a pre-tapped closure 20 onto a pre-tapped container 38 according to the teachings
    BE2017 / 5315 of this description. In step 102, a dummy 10 is formed from a disc of aluminum or other suitable metal. The dummy is generally unstructured so that it includes only an upper portion 12 and a cylindrical skirt portion 14 protruding from the upper portion 12. In certain embodiments, a chamfer 13 is also formed in the dummy 10.
    In step 104, a liner 34 is attached to the closure 20. A measured amount of the material of the liner 34 is deposited in the dummy 10 on the bottom 36 of the top portion 12. Then, a punch spreads and shapes the liner material into the desired shape suitable for sealing. The coating 34 is a dummy-formed coating and can be formed using the coating machine provided by SACMI, as described above, or any suitable coating machine. The liner 34 formed in the dummy is formed in the dummy 10 for further metal forming operations because otherwise the punch spreading and forming the liner material would damage a closure thread if such a closure thread is formed in the skirt portion 14 of the dummy 10
    BE2017 / 5315 before the punch enters the dummy 10 to spread and form the coating material.
    According to an alternative embodiment, a preformed disc liner is received by the closure 20. A liner mounting ring previously formed in the dummy maintains the disc liner in position near the bottom 36 of the upper portion 12 where it can seal with the sealing surface 53 of the dummy. curl 54.
    In step 106, certain features are formed in the dummy 10. As described above, the dummy 10, with a coating cast in the dummy or without a disc coating, can be placed on a mandrel with corresponding wire features. A molding press can form the wire 26 of the closure 20 while the mandrel rotates the closure 20. According to an alternative embodiment, the mandrel can hold the closure 20 stationary while forming disks or rolls 46 or other forming device forms the wire 26 in the skirt 14 of the dummy 10. Simultaneously with or following the formation of the wire 26, a serration 29 may also be formed in the closure 20. In addition, slots 30 are made in a lower portion of the skirt 14. The slots 30 may be made simultaneously with or following
    BE2017 / 5315 either the formation of the wire 26 or the knurling 29 are formed. Slotting 30 allows the tamper-resistant band 24 to separate from the cap portion 22 of the closure 20 when the cap portion 22 is twisted by the consumer to release the thread 26 of the closure 20 from the thread 48 of the container 38 such that the cap portion 22 can be removed and the beverage becomes accessible to the consumer.
    According to certain embodiments, a reforming portion 56 may also be formed using suitable tools simultaneously with or subsequent to the formation of the wire 26, the knurling 29, and / or the slots 30.
    In step 108, the closure 20 is removed from the mandrel. This operation involves rotating the mandrel in the opposite direction of the molding direction to detach the formed wire 26 from the closure 20 from the wire from the mandrel without damaging the closure wire 26. Alternatively, any of the above described metal forming operations and removal processes can be used to form the features of the pre-tapped closure and to release the formed closure from the tool.
    According to some embodiments, the completion of this may
    BE2017 / 5315 step represent a pause in the process such that the coated closures are fully formed and fed or otherwise received by a sealing machine to be placed on the filled containers.
    In step 110, the pre-tapped closure 20 including the wire 26 is received by a closure head 42. According to an alternative embodiment, the pre-tapped closure 20 may be applied upstream of the closure head 42 so that it is not screwed onto the container, but rather onto the container. curl 54 of the holder 38 rests. By resting on the curl 54 of the container 38, the container 38 can be indexed under a closure head 42 such that the closure head 42 can be lowered into a position where it can grip and rotate the pre-tapped closure 20.
    In step 112, the pre-tapped closure 20 is turned to engage the preformed wire 26 of the closure into the wire 48 of the holder 38. The clamp 44 of the closure head 42 rotates with the closure 20, whether the closure 20 is upstream is applied to the holder 38 or is lowered directly onto the holder 38 by the clamp 44, an appropriate number of revolutions such that a single spiral wire 26 engages the closure in a corresponding
    BE2017 / 5315 single coil wire 48 of the holder 38. Tightening the closure 20 to the wire 48 of the holder 38 also forms the seal between the liner 34 and the sealing surface 53 of the curl 54 of the holder 38. According to an alternative embodiment a plurality of closing threads engage corresponding multiple container threads to create the necessary clamping force to make the seal between the liner 34 and the sealing surface 53 of the curl 54.
    In step 114, the rotation of the closure 20 stops and the tamper-resistant tape 24 is rolled or crimped onto a mounting ring 52 formed in the holder 38. As described above, the shrink disks or rollers 46 can continue to rotate with the sealing machine head 42 after the clamp 44 has stopped rotating. The rotating shrink disks 46 apply a radial force component to form the tamper-resistant tape 24 on the container 38, more particularly on the portion of the mounting ring 52 of the container 38. The closing process comes to an end and the capped and filled container moves down in the fill line to be placed in further packaging suitable for shipment.
    BE2017 / 5315
    Certain steps illustrated in Figure 6 can be combined, modified, or deleted if desired, and additional steps can also be added to the flowchart. In addition, steps can be performed in any suitable order without departing from the scope of the description. For example, in an alternative embodiment, the dummy can be formed first, then the coils and slots, then the coating is deposited in the dummy, either a coating in the dummy or a preformed disc coating, then the reform can be formed on the closure , and finally the thread can be formed in the skirt.
    Containers capped with a pre-tapped closure according to the teachings of the present specification can form an attractive looking aluminum bottle container package that is easy for the consumer to grasp. In addition, the aluminum used for the container can be significantly reduced because the container does not have to resist axial forces associated with maintaining a seal between a liner and a sealing surface of a container finish while a wire is formed in the container.
    BE2017 / 5315 closure. Instead, by twisting a closure with preformed wires, the seal can be made by tightening the closure and engaging the wires of the closure in the wires of the container. Tightening the clasp to interlock the wires creates the clamping force to make the seal between the liner and the mouth of the container and less axial force is required.
    The embodiments described herein also increase the recyclability of the closures in that they are formed from a single metal material together with the resilient coating material. With conventional closures that use plastic inserts for the closure wire, the recyclability of such closures is reduced because the plastic insert tends to contaminate the aluminum stream. The plastic inserts are generally not recycled and must be separated from it
    aluminium from the closure. Removal of plastic material includes burning it of the plastic material an oven, what as less environmentally friendly can become
    considered.
