EP2408683B1 - Lid of a container - Google Patents

Description

The invention relates to the lid of a container, in particular a beverage can, with an essentially flat lid mirror and a preferably folded edge area, at least one reclosable pouring opening being arranged on the lid mirror, with an essentially one-piece closure means belonging to the pouring opening, which is completely on the underside of the lid mirror is attached in a rotationally fixed manner and with an actuating means which is connected to the closure means and penetrates the lid mirror and which is arranged on the top side of the lid mirror and is accessible from the outside, the closure means being adjustable from a closed position by actuating the actuating means to an open position, and wherein the actuating means has a holding element which cooperates with the cover mirror when the closure means is in the open position.

Numerous beverage cans have become known which have a reclosable pouring opening. For example, the DE 196 13 246 A1 a closure means applied to the already existing lid with essentially the same diameter, which closes a pouring opening in the lid by twisting. Similar devices, with some of these closure means only partially covering the lid, are DE 196 13 256 B4 , of the DE 197 06 112 C2 , of the EP 1 247 752 B1 or the US 6,626,314 B1 described. A disadvantage of these closures is their mostly complicated structure, which also requires structural changes to the lid area of the can. Resealable cans are also in US 6,626,314 B1 and DE 203 19 105 U1 disclosed.

Another group of closure means for beverage cans consists of a tear-open tab which is fastened to the can lid, for example by means of a rivet connection, the handle part of the tear-open tab being simultaneously designed as a closure means for the pouring opening, which after opening the pouring opening by twisting and / or flipping the Tear tab closes the pouring opening again. Such elements are among others in the DE 197 46 539 A1 , of the DE 203 19 105 U1 , of the EP 1 190 952 A2 , of the EP 1 097 086 B1 and the EP 0 433 502 A1 shown. These beverage cans all have a closure which is applied to the pouring opening from the outside and in some cases protrudes beyond the edge of the lid, so that it can be removed unintentionally and the contents of the can are thus exposed to the environment.

The GB 2 331 284 A finally describes a closure system consisting of a tear-open tab for exposing a pouring opening and a closure means which is arranged on the underside of the can lid inside the can, a spring element pressing the closure means against the pouring opening. In order to be able to empty the can, parts of the closure must be pushed against the tear tab. This closure means has the disadvantage that it has an extremely complicated structure and requires a change to the usual can lid. The closure device can also be of a somewhat simpler construction, also multi-part US 3,889,842 are removed, which also requires an elaborately modified lid. In the US 4,746,032 A similar reusable closure means are described.

The US 5,812,189 A describes a lid of the type mentioned with an additional closure means, which is arranged inside the beverage can and is pressed by spring force against the drinking opening. This closure system is also a hindrance, particularly when the container lid is being mounted on the beverage can during the filling process.

It is therefore an object of the invention to eliminate the disadvantages of the prior art described above and to provide a lid for a can, which has a secure closure system for reclosing the can, which can preferably be mounted in a commercially available lid in a simple and inexpensive manner.

This object is achieved according to the invention by a cover according to claim 1
solved in that the closure means can be moved from the closed position substantially perpendicular to the lid mirror into the open position and that the actuating means covers the pouring opening in the closed position. In order to be able to transport the beverage can safely after opening it for the first time without, for example, unintentionally pressing in the closure means to release the remaining contents of the beverage can, in a further preferred embodiment of the invention the actuating means covers the pouring opening in the closed position. This prevents, for example, when the reclosed beverage can is transported in a pocket, further objects in the pocket can move the closure means from its closed position into an at least partially open position, and thus the contents of the can pour into the pocket.

According to the invention, the closure means has a fastening part which is in a non-detachable connection to the lid mirror, and a closure region which closes the pouring opening in a liquid-tight manner, wherein a joint is provided between the fastening part and the closure region, about which the closure region of the closure means can be pivoted against a restoring force, and the joint is designed as an area with increased flexibility between the fastening part and the closure region. In a particularly simple and inexpensive embodiment of the invention, this joint is designed as an area with a smaller material cross section located between the fastening part and the closure area. If the closure means is made of an elastic material, the closure means is folded away when the actuating means is actuated, a force corresponding to the elastic properties of the material of the closure means having to be applied for this.

By attaching the preferably one-piece closure means in a torsion-proof manner, for example by gluing or soldering to the underside of the cover mirror, rapid assembly of the closure means on a commercially available cover is possible, with no or only slight change of the cover, for example a simple punching out for the Carrying out the actuating means through the cover are necessary. In particular, the edge region of the lid remains unchanged, so that the lid can be placed and fastened on the container, in particular on the beverage can, in the usual way.

In a preferred embodiment of the invention, the actuating means can be rotated essentially in one plane parallel to the cover mirror. Alternatively, it can be moved. The movement of the actuating means on the one hand removes the closure means from the pouring opening, preferably moving it essentially vertically out of the closed position, in particular by folding it away into the interior of the can, on the other hand the actuating means itself releases the pouring opening.

It is particularly easy to manufacture and therefore inexpensive if the closure means is designed as a two-component injection molded part.

When actuated, the actuating means connected to the closure means - it can also be formed, for example, in one piece with the closure means - causes the closure means to be folded out of the plane of the pouring opening into the interior of the can, that is to say can be moved into the open position essentially perpendicular to the can level. this releases the pouring opening and thus the contents of the can can be removed.

In order not to require constant force on the closing means when emptying the can, the holding element of the actuating means is advantageously designed as a detent for receiving at least one edge of the cover mirror when the closure means is open. As a result, the closure means is fixed in the open position and the contents of the can can be removed without having to exert any additional force on the actuating means. Alternatively, the locking means can be held in the open position by a latching hinge.

The actuating means can be designed differently. In a preferred embodiment, it is wedge-shaped. The wedge surface can be straight or helically curved.

In another embodiment of the invention, the actuating means is arranged on the surface of the lid mirror so as to be rotatable essentially about its central axis running perpendicular to the lid mirror, wherein it acts on the closing means when it is turned, so that the closing area is pivoted into the open position.

In a further variant of the invention, the actuating means is designed as a lever with a latching lug that projects substantially perpendicularly from the cover mirror.

An improved sealing of the pouring opening by the closing means is given if an additional sealing means is arranged between the closing area of the closing means and the lid mirror. This can be arranged, for example, on the side of the closure means facing the pouring opening. It can also be attached to the underside of the can mirror, advantageously enclosing the edges of the pouring opening in order to prevent injuries, for example when drinking from the can.

Preferably, the sealant simultaneously forms the area made of elastic material, so that this reduces the number of individual parts of the lid and thus, according to the invention, a higher stability of the closure of the pouring opening of a beverage can is achieved.

Packaging security is an important aspect, particularly with food packaging. In the context of this disclosure, this means protection in which the contents of the food packaging, in the present case the contents of the beverage can, are protected from manipulation or removal until the end user opens them. For example, the pouring opening is preferably sealed with a seal before the first opening. In the simplest case, this seal is, for example, a badge or a label which has to cover and remove the pouring opening before the can contents can be removed.

In another embodiment of the invention, the seal is designed as a pre-punched closure flap which is pulled off when the container is opened for the first time and thereby releases the pouring opening in the lid mirror.

In a further variant, the pouring opening is closed with the closure means before the first opening, the actuating means having a securing device. For example, the actuating means can be provided with a label which at least partially covers the lid mirror, so that the label tears when the actuating means is actuated and thus indicates manipulation of the container.

Particularly preferred is that securing device which has a predetermined breaking point which is broken open when the container is opened for the first time. If, for example, a label is used as a securing means, it can under certain circumstances be removed entirely and put back on the container without a glance at a difference from an untouched label being recognizable. A manipulation of the contents of the container would not be recognizable at first glance. In the case of a securing device with a predetermined breaking point, however, manipulation of the seal cannot be made unnoticeable again and is therefore particularly safe for the end user.

In a further embodiment of the invention, in addition to the pouring opening, a ventilation device is provided which can be closed by the closure means together with the pouring opening. This ventilation device allows a particularly simple emptying of the can contents without interruption due to negative pressure in the beverage can.

It is particularly cost-effective if the closure means and / or the actuating means are made of plastic. Of course, in the case of food packaging, the material used must be suitable for food.

As in Fig. 1 shown is the closure means
a substantially flat plate, which is divided into two areas by a bulge 2. This bulge essentially represents a joint 2 which has an elastic region 21, the closure means 1 being manufactured in particular as a two-component injection molded part. The area with the smaller area is the fastening part 3 of the closure means 1, which serves for the rotationally fixed fastening of the closure means 1 on the underside of the lid of a container. On the area with the greater extent, the closure area 4, there is an attachment 5 with a T-shaped cross section, which is made in one piece with the closure means 1. In the embodiment shown, the closure means 1 is made of a flexible material, for example plastic.

An actuating means 6, which for example according to FIG Fig. 2 be wedge-shaped, attached. For this purpose, the actuating means 6 has a recess 7, the cross section of which essentially corresponds to that of the attachment 5. Fig. 3 shows the closure means 1 with the actuating means 6 attached.

The closure means 1 is attached to the underside of a container lid 8, in particular to the underside of the lid mirror 9 of a beverage can. In this case, the closure area 4 closes a pouring opening 10 arranged eccentrically on the lid mirror 9. The T-shaped attachment 5, on which the wedge-shaped actuating means 6 is placed, projects through a recess 11 in the middle area of the lid mirror 9. For Release of the pouring opening 10 by pivoting the closure area 4 of the closure means 1 from the plane of the cover mirror 9, the actuating means 6 in the direction of the arrow Fig. 4 moved in such a way that the two legs 12, 12 'slide between the cover mirror 9 and the closure means 1. The elastic region 21 serves here as a joint 2, which forms the pivot axis of the closure region 4. At the same time, the wedge-shaped actuating means 6 is moved over the attachment 5, which engages in the receptacle 7 of the actuating means 6.

Due to the increasing cross-section of the two legs 12, 12 ', the distance between the cover mirror 9 and the closure means 1 increases, the closure region 4 being pivoted about a pivot axis lying essentially in the bulge 2. The bulge 2 located in the closure means 1 thus functions as a joint, about the axis of which the closure region 4 is pivoted out of the plane of the cover mirror 9.

In the in the 1 to 4 In the variant shown, an additional closure element arranged on the actuating means 6 is also provided, which is arranged on the side of the can mirror 9 opposite the closure means 1 for closing the pouring opening 10, the illustration of the additional closure element being dispensed with due to the clarity. This closure element has a shape substantially adapted to the pouring opening 10 and also opens the drinking opening 10 when the actuating means 6 is moved.

In 5 and 6 a non-inventive example is shown. The closure means 1 is in turn arranged on the underside of the lid mirror 9 in order to close the pouring opening 10 with its closure region 4. A sealing material 13 is arranged between the closure area 4 and the lid mirror 9, which additionally seals and thus prevents the contents of the container from leaking. The closure means 1 is in the Fig. 5 shown closed position pressed on the one hand by a bias resulting from the shape of the closure means made of elastic material against the pouring opening; on the other hand, the contact pressure increases further if, for example, carbonated drinks are filled in the container. Furthermore, an elastic region 21 is again provided in the region of the joint 2, which supports the closure region 4 from folding away when the actuating means 6 is actuated.

In this embodiment, the actuating means 6 is an essentially cylindrical lever which is connected to the closure means 1 through a bore in the cover mirror 9. Here, the lever is either in one piece with the Closure means 1 manufactured or is attached to this, for example via a screw connection. At its lower end facing the cover mirror, the lever 6 has a constriction 14, which in turn is adjoined by a region 15 with the original diameter of the lever 6. When pushing the lever 6 moves, as in Fig. 6 shown, the closure means 1 into the interior of the container and releases the pouring opening 10. The area 15 acting as a locking lug slides below the cover mirror 9, while the edge of the cover mirror 9 engages in the constriction 14. In this way, the closure area 4 is fixed in its folded-away position and the container can be emptied. In order to close the pouring opening 10 again, only the lever 6 has to be pressed in the direction opposite the pouring opening, so that the edge of the lid mirror 9 slides out of the constriction 14 again and the latching lug is released again.

The lid of 7 and 8 differs from the lids described above in that an enlarged pouring opening 10 is arranged laterally offset and in addition that a ventilation opening 10a is provided. Both openings 10 and 10a can be closed by a correspondingly designed closure means 1. In a not shown embodiment of the invention, a further closure element is additionally arranged on the outside of the can mirror 9 and prevents the closure area 4 from being inadvertently pivoted, for example during the transport of the beverage can in a pocket.

It can be clearly seen in the figures that the closure means 1 is only arranged in the area of the cover mirror 9 and the edge area of the cover 8 remains free. To assemble the closure means 1, it only has to be fastened with its fastening part 3 to the underside of the cover 8 in such a way that the closure region 4 completely covers the pouring opening 10. Thereafter, the actuating means 6 is fastened to the closure means 1 through a recess 11 or bore located in the cover mirror 9. Subsequently, the lid 8 can be attached to the container in a known manner without taking special precautions or having to make changes to the machines used for this purpose.

Another variant is the Figures 9 to 10b refer to. In turn, an actuating means 6 with a hook-shaped extension 61, which penetrates the can mirror 9, is arranged on the lid 8 of a beverage can. The extension 61 snaps into the closed position ( Fig. 9 respectively. Fig. 10b ) into a suitable recess 11 of the closure means 1 arranged below the can level. To open the drinking opening 10 by moving the actuating means 6 in the direction of the arrow in a plane parallel to the can level 9 Extension 61 moves along a bevel 16 of the recess 11, so that the closure area 4 of the closure means 1 moves into the interior of the can along the curved arrow, the pivoting taking place via a joint 2, which is designed as an area with a smaller material cross section.

A schematic representation of the closed position or open position
in an example not according to the invention, the Figures 11a to 11d be removed. In turn, an actuating means 6 is provided that from a closed position ( Fig. 11a respectively. Fig. 11c ) via a translatory, essentially parallel to the plane of the can mirror 9 sliding movement into an open position ( Fig. 11b respectively. Fig. 11d ) is transferred. In this case, an extension 61 of the actuating means 6 engages in a run-up slope 16 of a recess 11 in the closure means 1, as a result of which the closure region 4 is pivoted into the interior of the can around the joint 2, which is designed here as a material thinner. The run-up slope 16 can also have different areas with different slopes, so that during the opening of the beverage can by moving the actuating means 6, a high force is initially generated on the closure means 1 in order to overcome the possibly prevailing excess pressure in the beverage can, and then one less force for complete exposure of the pouring opening 10 is achieved by a lower inclination of the ramp 16. In the closed position, the actuating means 6 also functions as an additional closure element for securing the pouring opening 10.

The in the 12a to 12d shown embodiment of the cover 8 not according to the invention describes an actuating element 6 which, in addition to the extension 61, also has an elastic pressure element 62 which snaps into an abutment 111, is set up in a hinge-like manner and thus produces a long opening travel of the closure region 4 with a small operating path of the actuating means 6 . This makes it particularly easy to generate the high opening force for ventilation when the beverage can is opened for the first time.

In the Figures 13a and 13b An embodiment of the invention is shown, in which the actuating means 6 is pivoted normally about an axis onto the can mirror 9, a partial region 63 of the actuating means being non-detachably connected to the can mirror 9. When the actuating means 6 is rotated to open the beverage can along the arrow ( Fig. 13b ) a predetermined breaking point 64 is separated. At the same time, a security element is also obtained which indicates to the end user whether the beverage can has already been opened.

An alternative embodiment of the cover 8 according to the invention is shown in FIGS Figures 14a to 14c , shown, in which the actuating means is also brought in a rotary movement from the closed position into the open position, a helix 65 for vertical movement (arrow in FIG Fig. 14d ) of the closure means 1 is provided. For the sake of clarity, the 14c the closure means 1 and in the Fig. 14d the Helix 65 not shown.

In the in the 15a to 17b The variant shown is a closure 1, which is designed as a two-component injection molded part. The injection molded part consists of a closure region 4 made of essentially rigid material and a three-part fastening part 3, two outer fastening regions 3 ′, 3 ″ having an elevation 31 by means of which the closure means 1 can be connected to the can mirror 9. The one between the two fastening regions 3 ', 3 "central part forms a spring element,
that resets the closure area 4 into the closed position. Here, a projection 35 is provided on the spring element, which causes the spring element to be spaced apart from the can mirror 9, as a result of which the pretension necessary for closing the pouring opening 10 is built up on the closure region 4 of the closure means 1, which is preferably made in one piece with the spring element.

The closure means 1 also has a sealing element 13, the structure of which in particular the Fig. 16 can be seen. This sealing element 13 made of flexible material firstly seals the closure means 1 against the edge of the can lid 8, it being arranged along the outer edge of the closure means 1. On the other hand, it is arranged between the fastening part 3 and the closure region 4 and thus functions as a joint 20 Fig. 17b In the illustrated embodiment, the closure means 1 additionally has an area 2 with a reduced material cross section, which also supports the pivoting of the closure area 4 into the interior of the can. In another variant of the invention, this region functions as the sole joint, so that the fastening part 3 and the closure region 4 are designed as two separate parts (not shown).

The in the Fig. 18 shown variant of the lid 8 according to the invention has the previously discussed sealing element 13 and a rotatable actuating element 6 which acts via a helix element 65 on the closure means 1 arranged below the can level 9. The spring element 32 of the fastening region 3 is in this case formed in one piece with the closure region 4 and thus brings about the required pretensioning of the closure region 4.

In the 19a to 20 A further embodiment of the cover 8 according to the invention is shown with the associated actuating means 6, the closure means 1 being arranged below the can level 9. The actuating means 6 is in the Fig. 19a shown in the closed position, at the same time closing the pouring opening 10. In the Fig. 19b the actuating means 6 is pivoted parallel to the plane of the can level 9 in such a way that it opens the drinking opening 10, but the closure area 4 of the closure means 1 has not yet been folded into the inside of the can. By further turning the actuating means 6, for example clockwise, towards the fastenings 31, a mandrel 61 projecting through the can mirror 9 ( Fig. 20 ) a pivoting of the closure area 4 into the interior of the can to open the drinking opening 10. In Fig. 20 Three positions of the actuating means 6 which can be rotated along the can level 9 in this embodiment of the invention are shown again. In position 41, the actuation means 6 completely covers the pouring opening 10, so that the closure area 4 of the closure means cannot be inadvertently pressed into the interior of the can. In position 42, the pouring opening 10 is exposed, but is still closed by the closure area 4 of the closure means 1. Finally, in position 43, the drinking opening 10 is completely exposed and the contents of the can can be removed.

In the Figures 21a and 21b An embodiment of the cover 8 according to the invention is shown, in which the actuating means 6 is pivoted away from the pouring opening 10, for example by twisting, while at the same time a vertical force (double arrow) is exerted on the closure means 1 via an extension 61, which in this variant of the invention without Is executed joint and thus remains arranged essentially parallel to the can level 9 during the vertical movement.

In contrast, in the case of the 22a and 22b In the variant shown, the closure means 1 has a joint 2, which is formed here by reducing the material cross section, so that when the force exerts on the extension 61, the closure region 4 of the closure means 1 is tilted.

In the in the Figures 23a and 23b presented variant of the invention, the actuating means 6 has a latching cam 66 which engages in the pouring opening 10 in the illustrated closed state and in this way fixes the actuating means 6 in this position with increased resistance. It can also be provided that the detent cam 66 engages in a recess specially created in the can mirror.

In the 24a to 24c A similar embodiment of the cover 8 according to the invention is shown, in which, in addition to the locking cam 66, there is also a support cam 67 24 c) on one end of the actuating means 6, the locking cam 66 is raised by the abutment of the support cam 67 and the actuating means 6 then slides from the closed position into the open position. For the sake of clarity, the Figures 24b and 24c the representation of the extension 61 and its action on the closure means 1 are omitted.

In the in the Figures 25a and 25b shown variant not according to the invention, a lid 8 is shown with a closure means 1, which in turn is positioned below the lid mirror 9. This closure means 1 has four recesses 400, each of which has a fastening region 30 for fastening to the underside of the can mirror 9 and a lever region 50 which connects the fastening region 30 to the closure region 4. When the actuating means 6 is moved to open the beverage can, the closure region 4 moves along a circular path, the radius of which corresponds to the length of the lever region 50, the closure region 4 being aligned parallel to the can mirror 9. Fig. 26 shows the closure means from the 25a and 25b in a view from above and in a side view.
By attaching the generally one-piece closure means in a torsion-proof manner, for example by gluing or soldering to the underside of the cover mirror, the closure means can be quickly mounted on a commercially available cover, with little or no change in the cover, for example simple punching out are necessary to carry out the actuating means through the cover. In particular, the edge region of the lid remains unchanged, so that the lid can be placed and fastened on the container, in particular on the beverage can, in the usual way.

It is understood that the exemplary embodiments described above are to be considered in a non-restrictive manner for the invention. In particular, the shape of the closure means can be adapted to the respective opening to be closed. Likewise, the shape of the actuating means is not limited to the shapes described, but can take any shape that is suitable for fixing the locking means in a folded-away position. Furthermore, additional reset elements can also be provided, which force the closure means into a closed position.
