RELIABLE LID FOR BEVERAGES
TECHNICAL FIELD
The invention relates to a lid for a beverage package, preferably a beverage can, such as an aluminum, steel or PET can. The lid is easily resealable.
BACKGROUND
Beverage cans are well known. These beverage packages with metal lids have the drawback that they cannot be closed after opening. With an opened beverage package, there is the disadvantage that insects come onto the beverage and can fall into the container unseen. This can have adverse consequences for the consumer. When consumed in a vehicle, such as an airplane in a turbulence or walking through a train, there is a drawback that the drink leaves the opened package undesirably. It may further be desirable to consume the beverage in portions, for example at the workplace, with carbonated beverage, or for children. In order to counteract excessive alcohol consumption, it is desirable that a portionable packaging be made available to moderate and spread the consumption of, for example, alcoholic drinks such as canned cocktails or energy drinks. Some users prefer to drink straight from the can, others want to transfer the drink into a container, such as a glass.
Numerous resealable beverage cans and lids have been developed, but only a few found their way onto the market. This includes the XO from Xolution GmbH based on an injection molded plastic component and the Bail Resealable End of BRE from Ball Corp. These proposals have the disadvantage that they are based on quite complex mechanisms. This means that a consumer is not familiar with the opening and closing mechanism and new actions must be learned. The proposed solutions introduce new materials, such as plastic seals. This has the drawback that a different type of material is introduced. This is disadvantageous for recycling. The proposed solutions introduce quite a lot of extra material. Extra material often means extra thickness and a corresponding reduction in production speed on an assembly line. In addition, this goes against the trend in the industry, with can builders looking for ways to reduce weight so that the beverage packaging is less harmful to the environment. This is an important brake on proposals that work with material addition. Mechanisms based on a hole with sealing elements, such as a cap, are not hermetically closed. There is a problem with gas tightness.
US 7,823,740 describes a closing mechanism based on a rotational movement and additional material above and below the lid of the beverage can. This closing system continues
B E2017 / 5492 the lid, which is detrimental to safety. Leaks can occur. This system is not odor-proof and therefore not very suitable for energy drinks such as RedBull or Monster.
EP 2 032 452 describes a reclosable can based on a membrane hanging below the beverage opening closure and attached to the fixation point at the bottom of the pull lip pressure point. This curved manner of suspension is prone to scooping up drink and consequently sticking and sticking the membrane. In addition, the fixation of the membrane to the lid is based on a fastening element passing through the lid. The integrity of the lid was therefore abandoned. This increases the chance of leaks. The embodiment in Figure 5a is based on two rivets. The groove cannot be torn open but must be pushed open. The pull tab is attached to the cap top and cannot move independently.
NL 1010231 describes a closure proposal based on a rotary movement of the pull tab and snapping of the pull tab into the inner edge of the lid for closure. There is a risk that the end of the drinking lip that is pushed into the pouring opening is contaminated. The can opening is closed from the outside. Additional disadvantages are the risk of bursting with pressure in the can as well as external force on the central part. The thickness of the closing mechanism is also disadvantageous. When closed, the pull tab must be rotated 180 degrees and positioned accurately by the consumer.
EP 2 611 705 proposes a reclosing mechanism of a beverage can lid based on a combination of elements, ni. a top closure, closing flap and an elastic spring element. The elastic element is double pleated to be able to exert a springy effect on the top closure. This takes place. Venting is based on a lockable opening in the lid, namely in the shut-off valve part.
WO 2017/032752 also uses a top closure (cap top) and a separate shut-off valve and elastic spring element to reclose a beverage can lid. The venting mechanism is based on a cut in plate-like elements. Making a cut requires a separate production step.
So there is a need for additional improvements and especially simplification, without loss of reliability in the opening / venting and closing mechanism. The object of the present invention is to solve at least one of the above drawbacks. The object of the present invention is to offer a simple solution that is as close as possible to the habits as well as to the visual perception of a user and offers a producer the advantage of having an economically viable alternative, for example in terms of production speed, number of parts and material choices.

DETAILED DESCRIPTION OF THE INVENTION
Unless otherwise defined, all terms used in the description of the invention, including technical and scientific terms, have the meaning generally understood by one skilled in the art to which this invention pertains. Furthermore, definitions of the terms are included to better understand the description of the present invention.
As used here, the following terms have the following meanings: One, the, and the as used here refer to both the singular and the
B E2017 / 5492 plural, unless context dictates otherwise. A compartment refers, for example, to one or more than one compartment.
Approximately as used herein, which refers to a measurable value such as a parameter, an amount, a duration and the like, is intended to include variations of +/- 20% or less, preferably +/- 10% or less, more preferably +/- 5% or less, even more preferably +/- 1% or less, and even more preferably +/- 0.1% or less of the specified value, to the extent that such variations are suitable for performing in the described invention. It will be understood, however, that the value to which the term roughly refers is itself also specifically described. Include, comprising and includes and consisting of as used herein, are synonymous with contain, contain or contain and are inclusive or open terms specifying the presence of what includes e.g. a component and the presence of additional, unlisted components, features, do not exclude elements, parts, steps that are well known in the art or described therein.
Claiming numerical ranges by endpoints includes all cases and fractions included within that range, as well as said endpoints.
In a first aspect, the invention provides a lid, preferably for a beverage can, configured for combination with a spring element according to an embodiment of the invention and forming a reclosable lid, comprising a tear groove and a first and second fastening element, in which the first fastening element a pull tab is attachable, the pull tab has an operating end that can be lifted by hand away from the lid, and has an operative end opposite the operating end and positioned over the tear groove to apply force to the lid when lifting the operating end and opening the tear groove, provided with a pouring or beverage opening and a torn lid part, characterized in that the second fastening element is provided at the top of the lid for receiving the operating end of the pull tab and along the inside at the bottom of the lid is provided for inclusion of a spring element to reclose the lid n by repositioning the torn lid part in the aforementioned opening. This lid can make a container such as a can, lockable and portionable. This prevents excessive use.
The lid is preferably made of metal. Soda cans are generally made of steel or aluminum. Other materials in which a tear groove can be provided also apply.
By the term tear groove as used herein is meant a line along which the lid is thinner, thus weakened and can be opened by force. The tear groove can be symmetrical or asymmetrical.
B E2017 / 5492
The tear groove is preferably provided with a stop means for stopping the tearing of the tear groove. Preferably, this stopper is a stopper as described in WO2016 / 139274 and incorporated herein. Specifically, the stop means includes an abrupt change in the direction of the tear groove or an end point of the tear groove.
The above-mentioned embodiment has the advantage that a pouring opening can be reclosed along the bottom. By the bottom of the lid is meant the side of the lid facing the beverage container. This version is advantageous because the pull tab can be secured without additional material addition or thickness for the lid. No separate shut-off valve is required. The execution is hygienic. It is an additional advantage for a consumer that a beverage can is presented that is visually and practically close to a standard can.
Preferably, the first and second fasteners are selected from embodiments that do not pierce the lid and the tear-out lid portion. This has the advantage that leakage and manipulation can be excluded. No material should be provided to keep the piercing locations leak-proof. Preferably, the first fastening element is a bulge, more preferably an integral rivet obtained through a bulge in the lid. In other words, it is not a separate piece. The second fastening element preferably consists of two form-fitting protuberances, such as a push button. It is advantageous to attach these even further when the spring is brought together, for example by folding over an edge. Another possibility is glue.
The second fastening element is preferably a bulge with rounded edges, such as a circular shape or an oval shape. The second fixing element preferably has an edge for receiving the pull tab. The design and size of the edge is chosen in function of receiving and removing the pull tab. An edge is also advantageous as a support for the pull tab at opening. Tests have shown that the opening of a can lid according to the invention proceeds in phases. First, the pull tab is removed from under the pull lip edge, for example with a knife or fingernail. When released, the pull tab will remain tilted, resting on the bulge. This makes it easier to grab, lift and pull the pull tab to open the beverage can. A beverage can with this lid becomes more attractive for a wider audience of consumers.
The tear-off or tear-off lid part is also known to a person skilled in the art as a so-called cap top. To optimize the mechanism of tearing open and releasing a pouring or beverage opening, the cap top must be attached to the spring. This is possible, for example, by attaching the cap top to the spring, preferably over the entire contour, even more preferably over the entire mounting surface. Another possibility consists of providing a first receiving means on the spring element, preferably one
B E2017 / 5492 nose profile, and providing a form-fitting second receiving means on the tear-away lid part, preferably a hook. Most preferably, a combination of adhesive and form-fitting receiving means is made.
The tear-out part is preferably provided with a receiving means for one end of the pull tab. The recording means is preferably a hook. The end of the pull tab is at the end towards the receiving means, preferably provided with a pull lip guide / blocking means. Preferably the pull tab guide / blocking means is a groove. A groove shape is advantageous to ensure that the hook and pull tab engage properly. Guidance is thus provided when handling the pull tab. When closed, the groove in combination with the hook ensures that the pull tab cannot be moved back and forth undesirably. This prevents unwanted manipulation.
In use, the lid is further provided with a pull tab. This includes two functional ends. The active end can be gripped and lifted by a consumer. With this operation, the opposite end is pushed against the surface of the lid. Since this end is positioned above the tear-out part, the tear groove and the rivet are loaded and the tearing groove tears in.
The pull tab is preferably provided with a tamper-proof closure or so-called tamper evident closure, also referred to as sealing. Providing a seal on the pull tab has the advantage that virtually no additional material is required and no extra thickness is introduced. The provision of a seal has the advantage that the consumer can see whether the resealable can has been opened before.
The lid is preferably provided with a reinforcement randomly the first fastening element. The reinforcement is preferably located on the circumference of the first fastening element, but not in the area of the tear-off lid part. The use of a U-shape for the reinforcement is advantageous. When a consumer operates the pull tab and thus pushes on the tear-out groove by means of the pull-tab, the reinforcement ensures that the pushing forces are directed onto the tear groove. Possible damage to the can lid is absorbed by the point load.
The tear-off lid part is preferably provided with a receiving means for receiving the active end of the pull tab. This provides a housing for the pull tab end. The housing can control the end towards the lid when the pull tab is operated. For this purpose, the tear-off lid part or cap top can be provided with a hook or other clamping system.
The tear-off lid part is preferably provided with a receiving means for receiving the spring element. Recording preferably takes place without piercing the lid part.
B E2017 / 5492
A suitable receiving means is, for example, a protrusion in hook shape designed to fit in form with a corresponding hook shape provided on the spring element. This feature makes it possible to easily combine both parts.
The lid is preferably provided with a blocking means for temporarily positioning the pull tab in an approximately vertical position relative to the lid after tearing out of the tear-off lid part. This is also known to a professional as a so-called latching system. In this way an aid is provided for better opening of the pouring opening. This is especially interesting for large cans of 0.5 liters and more. There is less chance that the strength of the drink when pouring will make it hit the cap top and close the lid. The blocking means helps to open the opening because the movement of the pull tab is hindered. In addition, the cap top is given some extra depth. The blocking means is, for example, a reinforcement provided in the lid at the bottom of the pull-tab end for opening the cap top.
In a second aspect, the invention provides a spring element suitable for being included in a lid according to an embodiment of the invention to form a reclosable lid, characterized in that the spring element is provided with a protrusion for receiving in a fastening element of the lid, preferably without piercing of the lid, and wherein said fastening element on the opposite side of the lid is also provided for receiving the operating end of a pull tab.
The lid is often stamped from a coated lid. Avoiding a pierced lid has the advantage that the coating of the lid is not damaged. The coating step should not be adapted to the use of the spring element.
In a preferred form of a spring element according to the invention, the surface of the spring element mainly follows the contour of the lid, preferably of the bottom of the lid. The bottom means the surface facing the contents of the beverage can.
This embodiment has the advantage of providing a large surface area to apply force to. When the contour of the spring mainly follows that of the lid, simple means can be provided for securing or clamping the spring to the edge.
A spring element according to an embodiment of the invention is preferably provided on the periphery with one or more, preferably two or more, upright edges, designed to fit the edge of the lid. These facilities are simple
B E2017 / 5492 means for securing or clamping the spring element. This works efficiently and without much addition of thickness or material.
A spring element according to an embodiment of the invention preferably has a thickness between 0.05 and 0.10 mm, more preferably between 0.07 and 0.09, most preferably 0.08 mm. These thicknesses bring very little extra material and weight. They are suitable for enabling the production of beverage cans at high speeds.
A spring element according to an embodiment of the invention is preferably made from a resilient material, preferably selected from spring steel, stainless steel spring steel or a polyester such as polyethylene terephthalate (PET). The material in which the lid, spring element and can are made is preferably of the same type; such as metals or plastics. This is beneficial for recycling. The spring element is preferably provided with a coating. The spring element is preferably made of coated spring steel or stainless steel spring steel. Inox spring steel should not be coated.
One or more folds in the spring element arise in use as follows. A spring element made of flexible or elastic material is provided. During assembly, the spring is fitted tightly in the cover, on the sealing surface. When canning or bottling, the lid becomes fully convex and the spring partly due to pressure build-up. The pressure results from the use of carbon dioxide or liquid nitrogen. In the case of the spring, this is partly in view of the fact that it cannot fully follow the movement of the lid because the pressure above and below the spring is equal. This is advantageous because in this way the spring is partly free relative to the sealing surface and can thus circulate drink freely. Upon the unsealing, and I ^th time de-aerate the lid will implode a result of which the spring will flatten out. The spring no longer seals as the pull tab already exerts force on it.
Preferably, additional aids are provided on the spring element for folding the spring element in use and / or for better introduction and circulation of air and / or degassing.
The provision of a slit-shaped bulge in the spring element, preferably in the zone located between the second receiving means and the beverage opening, is advantageous to promote further folding of the spring element in use. The location between the second intake means and the beverage opening, whereby the sealing zone is not cut, is most effective.
Venting of the can lid at opening is enhanced by providing a vent hole in the spring element. Providing a thickening on the spring element facing the lid promotes air circulation and helps evacuate carbon dioxide or nitrogen.
B E2017 / 5492
A spring element according to an embodiment of the invention is preferably provided with a nose for form-fitting recording in a recording means provided on the tear-off lid part. The recording means is preferably a hook. Adhesive can be used when joining both parts together.
In a third aspect, the invention provides a reclosable lid comprising a lid as previously described comprising a pull tab and a spring element according to an embodiment of the invention, characterized in that the pull lip and the spring element are received on an opposite surface of the lid using the same fastening element.
In a further aspect, the invention provides a container for a liquid or beverage, preferably a beverage can, provided with a spring element according to an embodiment of the invention, preferably also provided with a reclosable lid (100) an embodiment of the invention, and the beverage container being made of aluminum, steel or a polyester such as polyethylene terephthalate (PET). The latter embodiment is known under the name PET can.
A standard beverage can is coated on the inside. This prevents, for example, that cola acquires a metallic taste. It ensures better shelf life.
Preferably, the tensile strength for opening the tear groove of a beverage container according to an embodiment of the invention deviates by no more than 10% from the tensile strength for opening the tear groove in the absence of said spring element. Preferably, less force is required to open the tear groove in a reclosable can according to an embodiment of the invention. Preferably, the difference in strength is less than 100 grams, more preferably less than 80 g, most preferably less than 50 g.
A beverage can according to an embodiment of the invention weighs less than 10%, preferably less than 5%, heavier than the non-spring beverage can. As a result, for a 10 gram can, less than 1 gram is added. This is little for an extra mechanism and additional functionality. In addition, the easier the lid opens, the shorter the pull tab can be. A shorter pull lip disturbs less when drinking.
In a further aspect, the invention provides a method of producing a resealable beverage can, comprising the steps of:
- provide a container for the reception of drinks with at least one open end,
- providing a reclosable lid according to a preferred form of the invention,
- closing the open end of the aforesaid container with the aforesaid resealable lid, thereby providing the resealable beverage container,
- optional repeat of the above steps.
B E2017 / 5492
In a method of producing resealable beverage cans according to the invention, the resealable lids are preferably stacked. Preferably, a Stack of resealable lids is formed and the Stack is conveyed in a slipper to a conveyor belt with beverage cans for assembly. The merge can take place in a seaming / seaming device. For non-carbonated drinks, such as fruit juice, drops of liquid nitrogen are added to the can for sealing. This ensures pressure build-up. The can lid can bulge.
The production speed of a method according to an embodiment of the invention is preferably at least 1200, preferably at least 1400, even more preferably at least 1600 and most preferably at least 2000 resealable beverage containers per minute. A standard beverage can production line had a production speed of 1200 cans per minute in 2014. The most efficient production lines currently produce at a rate of 2000 cans per minute.
A lid with spring element according to the invention is suitable for use in existing production lines. There is no brake on the current speed of a standard can production line. No production capacity has to be sacrificed for the production of cans resealable compared to non-resealable ones. This is a very great economic advantage. No new investments are needed at the bottling line.
In a last aspect, the invention provides a method for using a container according to an embodiment of the invention, the method comprising the following steps:
- operating a pull tab at the operating end in a direction away from the lid, whereby the lid opens along a tear groove, tears a lid part and creates a pouring or beverage opening;
- actuation of the pull tab at the operating end facing in the opposite direction to the lid, whereby a spring element, included in a second fastening element at the bottom of the lid, repositions the torn lid part in said opening and the accommodation of the operating end by said second fastening element on the top of the lid, reclose said lid.
The introduction of a fixing element for both the pull tab and the spring element means that the entire construction is simplified. A separate shut-off valve is no longer necessary. The closing mechanism is now based on the action of the spring element on the one hand and the pull tab on the other. Additional venting facilities are also no longer necessary. The spring element is made thin in order to be accommodated in the lid and to
B E2017 / 5492 have a springy effect. This also ensures that the spring can bend. This will benefit the venting.
The following describes the use of a beverage can according to the invention. The opening and reclosing of the, preferably metal, lid takes place as follows. First of all, the operating end of the pull tab is pulled up away from the lid. This loads the part in the lid where the tear groove is located. The tear groove opens and a first small opening is created. Carbon dioxide or nitrogen gas present in the beverage can may escape. This is accompanied by a Pssscht sound. This is the vent. When the pull tab is pulled up further, the tear groove opens further and the cap top tears completely. There is a spring element under the lid. This is included in a bulge that received the pull tab on the opposite side of the lid. In turn, the spring element carries a bulge that fits the shape with a provision on the cap top. As a result, when the tear groove tears out completely, the cap top remains behind on the spring. Movement of the pull tab pushes the spring inside the can and releases the torn opening. To reclose the lid, the pull tab is pushed back towards the lid. This causes the spring element to return towards the lid opening. The cap top comes back between the tear groove. Due to the tension on the spring element and suction force, the torn lid part will strike into the opening, whereby the spring element provides closure. The pull tab is secured behind the fastening element, here a bulge. The opening and closing can be repeated several times with minimal movement of the pull tab. The risk of the pull tab breaking off is small. A coating can be applied to the sealing surface or to the spring.
The invention is further illustrated by examples and figures. These are not limiting. Preferred forms of the invention are illustrated in Figures 1 to 40.

In Figure 1, a three-dimensional image is shown with a reclosable cover 2 according to the invention, including a spring element 5 according to the invention. The lid part is cut away half way to show the reception of the spring element 5. The lid is seamed and open. Furthermore, the pull tab 16 can be seen with an operating end 4 and an opposite end 18 which lies above a tear-away part 3 of the lid 2. When the pull tab 16 is operated, the end 18 will exert force on this lid part. Due to the presence of a tear groove 9, a part of the lid will tear out. This part remains on the spring 5 and will move with the spring and the movements of the pull tab 16. An important aspect of the invention is the fact that no fasteners passing through the lid are used. The integrity of the lid, except for the tear-off cap top 3, is preserved.
B E2017 / 5492
Example 2, as shown in Figures 2-4 and 11, concerns a reclosable lid 100 with a tear groove 9 and stop element 22. Figure 2 shows a top view of the lid before use. The closing lid of the pouring opening 3 is symmetrical, except for the stop element. It is provided with a bulge 33. This bulge can be used for applying glue. The lid is provided with a pull tab which engages at the operating end 4 over a fastener 12. The fastener in the picture is a protrusion 12. At the opposite end the pull tab is with the end under a lip 7. It is advantageous that on the end a groove 47 is provided to fit the lip 7 end. On the one hand, this groove provides guidance at opening. When closed, it ensures that the pull tab cannot be moved back and forth unintentionally. The pull tab is attached to the lid by a second fastener, here a rivet 20.
Figure 11 shows a top view of the lid of Figure 2, but without a pull tab. This drawing shows the U-shaped bulge 51 randomly at the rivet 20. In a standard tin this part is smaller. In this embodiment, the bulge 51 provides additional reinforcement around the rivet 20. Also, some extra height is provided.
Figure 3 shows the cover 100 of Figure 2 in cross section. It can be seen from this that the pull tab with a receiving element 44 at the end is received in an inlet 43 under the lip 7 and rests flat against the lid. The pull tab is fixed to the lid with a rivet 20. The pull tab opening surrounds a second fastener 12. A spring element 5 rests against the bottom of the lid. The edge of the spring 31, which rests against the edge of the lid 30, is shown on the right-hand side of the drawing.
Figure 4 shows a Stack of 36 unfolded lids 2, 2 ', 2 as shown in Figure 3. The lids are supported on the rim. The space between different lids was used for the closing mechanism. Furthermore, it can clearly be seen that a reclosable lid with spring element 5 'according to the invention causes hardly any extra thickness compared to a standard tin without spring. This is the case both at the top and bottom of the lid, since rivet 20 is also present in a standard can and protrusion 12 is no thicker than a pull tab of standard thickness and the nose 7. The nose 7 is new and not known from standard versions.
Example 3 concerns the first phase of the lid opening. Figures 5 and 14 show the individual parts, namely an unfolded cover 2 as shown in Figure 2-3, and a spring element 5 for making the cover resealable. The figure shows a view of the bottom of the lid 2. Compared to the lids shown earlier, this lid is not seamed. In Figure 5, the sealing surface 10 was additionally emphasized by marking it in black. In Figure 14, the part in black that closes the pouring opening, the so-called cap-top, was indicated. Where the bottom of the lid is colored black in the drawing, the spring comes against the lid. The part shown in black is preferably attached
B E2017 / 5492 on the spring, for example by sticking. The spring element floats in the other parts. The bottom of rivet 20 can also be seen. On the right is shown a preferred form of a spring element 5 according to the invention. The contour of the spring element mainly follows the contour of the lid 2. The notch 60 at the top and the openings 21; 11 ensure a better supply of air. The bulge 19 is mainly reinforcement of the spring upon closing. The adhesives for applying the spring to the can lid are the element for coupling with the can lid 23, the form-fitting nose profile 37 and the edge bosses 31.
Figure 6 shows the composite resealable lid. The lid is seamed. The condition depicted is the initial opening. By operating the pull tab at the operating end 4; i.e., pulling away from the can lid, the opposite end pushes the pull tab towards the pouring lid closure lid 3. The pushing force first creates a small opening and venting. The tear groove then tears open further. The tear groove opens on both left 41 and right 42. This is shown in the detail image on the right. The pull tab was omitted. This also shows the U-shaped reinforcement which has been randomly arranged in the rivet 20 and outside the closing lid 3 in the can lid 2. Furthermore, the nose 7 and thickening 50 which form an inlet 43 for receiving the push end of the pull tab. The bead 50 has rounded edges so that the end of the pull tab 18 can slide over it as the can is opened further (see also Figures 3, 8, 13, 18).
Figure 7 shows a cross-section through the resealable can lid with spring element of Figure 8, mounted on a previously open end of a beverage can 35. The lid overlies the rim of the beverage can. It was connected to the jacket of the can 1. The operating end 4 of the pull tab is slightly raised.
Figure 8 shows a cross-sectional and detailed view of the condition as shown in Figures 6 and 7. The lid is seamed and opened. It can be seen from this that at the initial opening of the tear groove 9, a small opening 8 is created through which gas bubbles 41 can escape (arrow 32). This provides venting of the can and gives the characteristic Pscht sound. This drawing also clearly shows that at opening the tamper proof seal is broken and the connecting element 13; 14 are no longer connected. In this state, the pull tab element 44 is still received in the recess 43 under the lip 7.
Example 4 concerns the second phase of the can opening with the formation of the beverage and pouring opening by pushing out the closing lid of the opening 3. Figure 9 shows a seamed tin lid with pushed-out lid. This sealing was achieved by further removing the pull tab end 4 further from the can, with the result that the tear groove opens completely. The closing cover 3 is fixed on the underlying leaf spring 5 and moves inwards. This creates tension on the leaf spring. A cross section through the lid and the
B E2017 / 5492 spring as shown in Figure 9, is shown in Figure 10. Figure 10 shows a seamed and unsealed lid. Note that the pull tab is slid over the protrusion 50 and pushes the leaf spring 5 away from the pouring opening.
Example 5 concerns a seamed can lid in drinking position, as shown in Figures 12 and 13. For users who wish to consume a beverage from the can, the opening may be left less open. This is already achieved by tilting the pull tab, or moving the pull tab end 4 through an arc of about 120 degrees and then partially fold back to the position as shown. The drawing in Figure 12 clearly shows that the pull tab has a recess 47 for engaging the lip 7. Figure 13 shows a cross section through various protuberances. It can be clearly seen how a first bulge 12 and form-fitting part 23 on the spring are pushed together and show a small deformation due to the tightening both. This is like in a push button. A second bulge, here a rivet 20, ensures that the pull tab is fixed to the lid 2. It can also be seen how the spring 5 is received in the hook 7 on the cap top and how the end of the pull lip 18 is provided with a groove 47 which is received in the recess 43 under the hook 7. The pull-tab end 18 will pass over the oblique slope of thickening 50 upon further opening of the lid. The shortest slope of bulge 50 functions as a stop when the lid is opened even further by an almost vertical position of the pull tab. Connecting elements 13 and 14 of the pull tab are broken; the can lid is unsealed.
Example 6 concerns the characteristic of the so-called tamper-evident closure. This is illustrated in Figure 15. Figure 15A shows the closure in the unsealing state. Figure 15B shows the condition after can opening. It can be seen that connecting elements 13 and 14 are first connected. By manipulating the pull tab, the connection between the connecting elements 13 and 14 is broken. The way the sealing is performed is advantageous because it uses little material and does not introduce additional thickness.
Example 7 concerns alternative embodiments of a spring element according to the invention. In Figure 16, two other possibilities are shown for a spring element suitable for use in the present invention. Insertions 28 ', 29' can be used instead of openings; 25. The bulge 19 ', 19 at the bottom of the spring element, located opposite the edge bosses 31', 31, can also be positioned in different ways with respect to the lid of the pouring opening 3 ', 3. On the left is an embodiment in which the bulge partly follows the circumference of the circular spring element. On the right is an embodiment in which the bulge 19 partly follows the contour of the lid of the pouring opening 3. This bulge provides reinforcement on the spring. Figure 17 shows a three-dimensional representation of the spring element of Figure 16, right side, but without the cover of the pouring opening 3. This gives a
B E2017 / 5492 better seen on the upright edge on the spring circumference 31 and on the design of the recess 25.
Example 8 illustrates the second application of mound 50. This protrusion on the one hand ensures that the pull tab 16 is received in the inlet 43 in the non-activated state. When activated, the pull tab 16 slides over the beveled left wall to be blocked on the opposite side of the bulge as shown in Figure 18. Figure 18 shows a seamed can lid. This prevents accidental closing of the pouring opening. The mound 50 can thus also serve as a blocking means for the pull tab 16. The embodiment shown in this example is interesting for use with large cans, such as 0.5 or 0.75 or 1 liter beverage cans. The blocking means 50 ensures that, when pouring or drinking, the beverage present in the can upon impact against the spring and the lid of the pouring opening does not push it towards the pouring opening. The necessary resistance is provided to leave the pouring opening open. It is only upon manipulation by a user, when the pull tab 16 is pleated back toward the lid, that the pull tab 16 slides over the mound 50 and takes it back into the recess 43. The opening of the pull tab at the operating end 4 is brought over the bulge 12 to complete the reclosing. Elements 7, 43 and 50 form a latch or blocking device (latching). These do not introduce additional thickness.
Example 9 concerns an alternative can lid, not seamed, with asymmetrical closure of the pouring opening. This embodiment is illustrated in Figure 19. To emphasize the difference from previous embodiments, a mirror line was drawn. This embodiment has many advantages. A stopper is no longer necessary. Because the right contour is shorter than the left contour 48, the shortest side will tear open first. Since the right side is closer to the pressure point, the venting after reopening is advantageous. The vent point is closer to the pressure point of the pull tab. Due to its location, forces are bundled on the shortest side. The asymmetrical tear groove 9, and thus also the opening, pours better.
Example 10 concerns alternative conical tear groove shapes and lids for sealing the pouring opening. The tear groove shown in the unfolded can lid on Figure 20 is more oval and narrower than the previous ones. The tear groove depicted in the unfolded can lid on Figure 21 has a wide base located near the edge of the can lid. The tear-off lid 3 covering the pouring opening narrows towards the pull tab 16. Here you can also see how the pull tab 16 and the tear-off lid 3 lie in a recessed part of the beverage can lid 1. This is formed by a relief cam 17.
Example 22 concerns a preferred form of a spring element according to the invention. Figure 22 shows a three-dimensional representation of a seamed can lid in a bottled state under pressure, provided with a spring element with a pleat according to an embodiment
B E2017 / 5492 of the invention. The seamed lid shown in Figure 22 is equipped with this spring element, typified by a centrally located pleat 24 in the leaf spring. The effect of the pleat 24 is illustrated in Figure 23. The top image of a seamed lid can shows a cross section through the pull tab. The bottom image is a section through the same lid, but rotated 90 °. The pleat 24 provides some extra space under the lid and ventilation when the tear groove opens. It ensures that the spring is open. When the tear groove is torn open, the spring is ready for venting the can. On other parts you can clearly see how the spring rests against the lid and provides sealing. The bottom image clearly shows how the spring covers some lid parts and floats relative to other parts. Good venting, with characteristic sound, shows consumers that it is a successful opening of the beverage can.
Example 23 concerns a preferred form of a spring element according to the embodiment. This is illustrated with reference to Figure 24. A top view is shown on the left and a cross-section on the right along line A-A. Instead of openings as shown in Figure 14, use is made of an additional bulge 62 which promotes further opening of the beverage opening and two trapezoid bulges 61. These promote the strength of the spring 5 around the beverage opening. Furthermore, the upright rim 63 is also space-saving and as a result the pouring opening and cap top 3 can slide closer to the rim or be made larger. Furthermore, an upright edge 63 is provided which follows the contour of the can. The slit-shaped protrusion 62 serves to promote pleats, to leave the spring more open and thus also to open the beverage opening more. The additional bulge 62 cannot continue, otherwise it will pass through the sealing surface.
Example 24 concerns test setups. These are shown in Figures 25 and 26. Figure 25 illustrates a test rig 45 to measure and compare the required tensile force for unsealing beverage can lids 2, 100. Figure 25 shows a measuring device 45 with pulley and disc weights. Additional weight 46 was applied until the resistance of the pull tab and tear groove was overcome and the pour hole was released. The amount of weight applied was noted and compared to standard non-spring loaded can lids as they are commercially available. The base weight was 1 kg. Each time, 50 g slices were added to tear open. The leverage effect is two times, since the radius of the wheel on the left is double that of the lever. Results of a comparative test are shown in Table 1.
Moreover, tests of beverage can lids with a subject showed that the provision of the pull tab received by a bulge, such as by a small rim, did not hinder the opening of the lid. The pull tab was first removed from behind the edge of the bulge. In a second phase followed the movement of the pull tab which loaded and opened the tear groove. The position on the edge of the bulge was advantageous. There
B E2017 / 5492 had more space to engage under the pull tab to operate the pull tab to open the lid.
Table 1: Tensile force test results for lid opening
Can lid type Need power to look withoutspring element open - positionof the technique Need power to cover with canspring element according to theinvention CDL 2.8 2.7 ISE 2.1 2.0
Figure 26 illustrates a pressure test setup 58 in which the can lid vent mechanism was tested. A standard bottled can was cut 3 cm below the counts. A spring element according to the invention was mounted against the lid using screws. The cover was received in the holder 55 of the test set-up and secured with a clamp 56. Compressed air was supplied to the chamber under the cover 52 by means of a compressed air supply 53 and a shut-off valve 54. The pressure was read on the pressure gauge 57. A constant pressure of 2 bar or more was maintained under the lid. Then the opening of the can lid was tested. In conclusion, it can be stated that the ventilation has remained standard. The can with spring opens with a pssscht sound as with a standard can. This is a recognizable sound for a user. This proves that the spring was open.
Figure 27 shows a reclosable lid according to the invention in a sealed condition. It shows a pull tab or pull tab, shown in red, (see tear groove and pull tab (pull tab) bridge).
Figure 28 shows a close-up view of the lid from Figure 27. This shows the tear groove with a stopper (to the left of the pull tab). The pull tab is attached to a first bulge, especially a rivet, in the lid. This is centrally located. Also shown is the pull tab enclosing a second bulge. The pull tab portion attached to the first bulge further has a breakable bridge connecting the operative end to the center portion. This piece is broken when the pull tab is operated. This is a visual indication to a consumer that the pull tab has been used before.
Figure 29 shows a section through the lid of Figure 27. The lid (blue) is provided with a spring element (white), with a thickness of 0.05-1.0 mm, at the bottom; and a pull tab (red) at the top.
Figure 30 shows a top view of a lid as shown in Figure 27, but without pull tab (pull tab).
B E2017 / 5492
Figure 31 shows a bottom view of a lid as shown in Figure 27, here with sealing zone but without spring element. The protruding part of the lid is colored black. The black part can be made of rubber, silicone or an elastic sealing material. It can be performed with or without coating. The sealing surface can also be coated on the spring itself.
Figure 32 shows the spring element. This is preferably carried out in a thickness of 0.05-1.0 mm. and treated spring steel, stainless steel spring steel or PET. In the latter case, the thickness is typically 0.4 mm. At the top center is a protrusion that is form-fitting with the second protrusion on the lid.
Figure 33 shows the resealable lid when open, suitable for drinking or pouring a beverage when the lid is provided on a beverage package. The seal or bridge with the pull tab (pull tab) is broken.
Figure 34 shows a cross-section of the lid shown in Figure 33. The lid is shown in blue, the pull tab in red and the spring element in white.
Figure 35 shows how different lids according to the invention can be stacked. This is possible even by using an additional element over a standard cover, namely the spring element, typically 0.05 - 0.1 mm thick. The Stacking lids show that the closing mechanism takes up very little space. The total thickness is equal to that of a standard lid. The lid stack is advantageous to be used on an automated production line.
Figure 36 shows a bottom view of a cover and of a spring element for attachment to the bottom of the cover, for assembly.
Figure 37 shows a lid in opened position with a bottom view of a section of the spring element.
Figure 38 shows a reclosed lid. Note that the bridge in the pull tab is broken. A detail view is shown in Figure 39.
