Description

The present invention relates to a lid of resealable containers, to containers, in particular to beverage cans comprising a lid of a resealable container, to methods for manufacturing such containers and to the use of such a container lid in accordance with the invention.

Non-returnable liquid containers have been used for quite a long time and have been widely used with many different shapes and sizes. Especially often for drinks use cans for a drink made of light metal, where the lid of the can is equipped with a so-called lever closure. According to a first embodiment, the part of the lid forming the dispensing opening is pressed in the direction of the interior of the can by manipulating such a lever closure and remains connected to the can lid without possible separation. According to another embodiment, the lever closure, together with a portion or part of the lid for the dispensing opening, is removed by manipulating the lever closure. Such closures are described, for example, in WO 97/030902, DE 10018685 C2, US 4148410, EP 564725 A1, WO 2005/056400 A1 and GB 2379917 A. When using such closures, the containers are effectively resealed with a portion of the lid pushed down or outward, essentially no longer possible. This is very disadvantageous, especially with large containers for the drink, as it is usually not consumed directly completely after the initial opening. If the drink in question is a sugar-containing soft drink, for example, there is a risk of insects getting into the container, especially during the summer months. In addition, the freshness, taste and quality of the drink are adversely affected if the drink is stored open. In particular, drinks containing milk or yogurt gradually lose their taste and quality or even become completely inedible if they are exposed to ambient air for a certain period of time. Capping devices that do not provide repeated closure of containers for containing carbonated drinks have shown that they are particularly disadvantageous. Without a suitable closure, carbon dioxide evaporates very quickly, leading to a loss of the characteristic taste of the drink.

Many attempts have been made to create resealable beverage cans. The first attempt to solve the problem was made for lids for cans that contained a dispensing hole at the very edge. Proposals in this direction are disclosed, for example, in WO 2007/039367 A1, WO 2008/054636 A2, DE 20 2005 019224 U1, US 3952911 and DE 60101995 T2. However, as a rule, such containers are not as impermeable, especially over a long period of time, such as, for example, cans for a drink made in the entire assembly of the can body and the lid of the can that does not contain a pre-made dispensing opening. The manufacture of such containers for a drink containing a pre-made dispensing hole, in most cases also requires very large material and labor costs and is very expensive if it is necessary to provide a high degree of tightness, especially after repeated closure.

For beverage containers that do not contain a prefabricated dispensing opening, re-closure devices are provided in accordance with another embodiment of a closure or part of the closure made with an additional closure after creating the first opening. Such devices are disclosed, for example, in DE 10018685 C2 and DE 9211883 U1. Instead of using a one-piece can lid, non-one-piece lids that are pivotally attached to the can lid are also known. According to DE 20300327 U1, after initial opening or tearing to open the dispensing opening, the flat part can be rotated relative to the axis of rotation on the surface of the lid to a position outside the dispensing opening. A similar closing device is used in WO 2005/056400 A1. A can lid is known from WO 99/67150 A1 for possible re-sealing, in which the dispensing opening is initially closed by a removable film, which is an integral part of the can lid. After removing such a film, a closure lid connected to the lid of the can by means of a loop from the film can be inserted flush into the dispensing opening. The closure option described in WO 99/67150 A1 is suitable for can lids made of plastic.

US Pat. No. 4,887,712 discloses a can for a beverage, a dispensing opening in which can be created by means of a lever closure. A part of the surface of the can lid, forming a dispensing hole, is pushed towards the inside of the can, and can be connected to the lid without the possibility of separation. The closure element, which is a rotational support relative to the attachment point, contains a convex section opposite the nose of the tongue, which corresponds to the contour of the dispensing opening and which can be inserted into it after rotation of the closure element to close. A sufficient degree of tightness, especially gas impermeability, cannot be ensured in this embodiment. The closure device described in GB 2379917 A corresponds essentially to a closure device in US Pat. No. 4,887,712.

Also according to DE 8911286 U1, the lid of the can may comprise a tongue for opening rotatably held on the wall of the lid. The rotatably held tab contains a closure element, which, in the closed position, is opposite the opening of the dispensing opening and can come into contact with it for closing. The tongue for opening and the capping element are made of sheet metal in the form of an integral part.

WO 2004/056667 A1 discloses a lid of a beverage can in which the catch portion of the tongue is designed to re-close the dispensing opening formed when opened by breaking along a predetermined breaking line. Also in this embodiment, the grip portion of the tongue is rotatably supported on an axis located in the lid so that it can rotate vertically, while the shape and size of the closure being adapted to the dispensing opening to provide a tight seal to a sufficient degree.

In DE 29914231 U1, a lid for resealing a can is provided by separating the entire can lid from the can edge by means of an edge with a seam that is less durable in the tear tab portion. The integrity of the lid of the can with this method is not violated, so that the lid can be placed again on the edge of the can after using the can.

To obtain closures with the possibility of resealing cans with a higher degree of tightness, according to DE 102005057755 A and DE 102005004759 A1, threaded closures must be connected to the can lid. This can be achieved, for example, by the destruction of the protective film at the initial stage of use of a threaded closure.

DE 69302424T2 discloses a closure for resealing a can lid, where a plastic jacket can slide slidingly on a metal push-open or tear-off tongue, said tongue being rotated relative to the attachment point and attached thereto by a clip. The peripheral edges of this slide-sliding shirt are designed so that the dispensing opening can be completely closed. In order for the pivotally held tear-off tab with the sliding jacket made of plastic to remain over the dispensing hole, a groove is made along the outer peripheral edge of the tongue, where the said groove engages with the peripheral rolled edge of the can lid. In this way, the position of the tear tab over the dispensing hole is fixed, but the tightness is not particularly high in this way.

However, re-capping closure options known in the art have their drawbacks and leave room for improvement, for example, regarding tightness in the case of carbonated drinks. Furthermore, re-cappable lid devices known in the art to date are generally not suitable in order to withstand with sufficient reliability the pasteurization conditions to which, as a rule, many drinks must undergo during mass production. If the dispensing or lid device does not allow pasteurization, during which the temperature is usually above 70 ° C and the internal pressures are up to 7 bar, preservatives should inevitably be used.

Since devices known in the art make it possible to pasteurize as a whole without affecting the installed capping device for re-capping, this is often done only when plastic parts are needed on the inside of the can lid. However, this poses a risk of dissolution of the plastic components used for placement in the pasteurized beverage.

An object of the present invention is, therefore, to provide a lid for a resealable container that does not have the disadvantages of the prior art and which, in particular, also provides the possibility of easy and continuous production under mass production conditions, while still being designed for beverage containers in which the drink continues to maintain its original quality, and in the case of carbonated drinks, the initial concentration of dissolved carbon dioxide for a longer period time after the first opening and re-closing.

Accordingly, a lid of a resealable container was developed having a lid surface with an upper and lower side and with a peripheral edge and a zone for a dispensing hole bounded by at least one fully or partially peripheral softened profile, a lever tab secured with fixing means on the lid surface rotation, to open at least partially, the zone so as to form a dispensing hole having a first end part and the opposite second the end part, where the first end part, in the opening position, can be brought into position or in the position to at least partially overlap the segment of the dispensing hole area, and where the second end part is on the opposite side of the fastening means relative to the first end part moreover, the lever tab contains a closure module on or near the second end portion, where said closure module comprises a closure girdle or a structural part that can be installed for support or which rests on the upper side of the surface of the lid, and which, in the capping position, passes through the dispensing opening, in particular in a sealing manner when placed on the upper side of the surface of the lid and, in particular, surrounded by the closure belt of the closure for re-sealing holes.

The opening position in the context of the present invention should be understood as the orientation of the lever tab on the surface of the lid, in which you can control the lever tab to open the area for the dispensing hole. The closing position from the point of view of the present invention should be understood as the orientation of the lever tongue, in which the closure module of the lever tongue is in position over the dispensing opening and may be, or, in particular, is in connection with said hole in such a way that it forms a closure for possible re-corking.

Depending on the type of container, the surface of the lid may be made of plastic, metal, or cardboard or thick paper, respectively, or consist of one or more of these materials. The same applies to the container body. The surface of the lid according to the present invention is a flat element, for example, of a layer of metal and / or plastic. In fact, the surface layer of the lid of the container according to the invention can also be a multilayer structure comprising, for example, a surface layer of metal containing at least a plastic film layer on the underside as a protective layer.

The lid of the container according to the invention may be an integral part or a separate part of the container. In the latter case, the container lid and the container body or container container can be sealed to each other in a manner known in the art, for example, by gluing or joining, for example, using a seam. For example, the peripheral edge of the lid surface may also include a flange for connection to the container body. The peripheral edge of the lid of the container according to the invention in a preferred embodiment may comprise a bulge extending axially from the upper side of the surface of the lid. In a suitable embodiment, this can be done provided that the axial thickening of the edge is made so that the extension of the thickening is greater than the extension of the thickening of the lever tongue in the axial direction relative to the surface of the lid in the opening position, when the area for the dispensing hole is still intact. In particular, the latter embodiment of the container lid according to the invention makes it possible without any difficulty to stack containers provided with such container lids.

The container body or container in the context of the present invention comprises structures with and without a bottom element. As a result of this, metal cans for a beverage, for example, are often made of two or three parts. That is, in a two-part container embodiment, said container is connected from a container body already containing a lower element, made in particular as an integral element, and a container lid. In an embodiment of a three-part container, said container is made of a lower element, a container wall and a container lid.

Re-closable container lids according to the present invention can be used for many types of containers. Some samples include beverage cans, such as carbonated drinks, cartons for milk, containers for (liquid) yoghurts, or packaging for fruit juices. In addition to beverage containers, the lid of the container according to the invention, of course, can also be used for containers in which liquid or powder food products such as oil, vinegar or flour are offered.

The lids of the containers of the invention are also suitable for containers containing personal care products, such as, for example, commercially available shampoos or shower gels.

The shape and size of the area for the dispensing opening on the surface of the lid can vary to a large extent and usually depends on the type of container used with which the lid according to the invention is proposed. In one embodiment, this can be done provided that the area for the dispensing hole is located at a distance from the fastening means and, specifically, near the edge of the surface of the cover. In a suitable embodiment, the area for the dispensing opening is defined by means of a fully or partially softened peripheral profile. The lids of the container according to the invention are preferred in that as long as the area for the dispensing opening remains intact, the penetration of liquid through the lid of the container is not possible, and with the maximum degree of reliability. In particular with regard to beverage cans, such a fluid tight zone for the dispensing opening often also refers to a notched wall (side), and a softened profile limiting or defining this zone refers to a notched profile.

The fastening means for such lever tabs on the surface of the lid, which can also be used with the lid of the container according to the invention, is well known. As for the device for opening it, the lever tab of the container lid is also known in the art as a lever closure. In particular, in the opening position, the first end portion of the lever tongue, also often referred to as the tip of the tongue, is aligned with a portion of the zone segment for the dispensing opening. When lifting the second end part of the lever tongue, the force is applied to the part of the zone for the dispensing hole by the first end part, or by the tip of the tongue, as a result of the lever acting, leading to the destruction of the weakened profile at or near the force application point, and to the portion of the lid surface that previously closed dispensing hole, and turning towards the inside of the container while opening the dispensing hole. The fastening means is preferably a rivet and is preferably located in the center of the surface of the lid. Depending, in particular, on the surface size of the lid, and in particular on the size of the dispensing opening, the fastening means can also be attached at a different location on the surface of the lid.

The second end portion of the lever tongue comprises a closure module, which is equipped with closure for resealing the hole, for example, in the form of a valve or valve cover. This valve may, for example, be connected to the closure module, in particular to the closure belt, by means of a hinge or a film hinge. The closure for resealing the hole in one embodiment of the invention, on the side facing the upper side of the surface of the lid, comprises a reversing stopper, which, in cooperation with the corresponding second stopper, provides an airtight closing of the opening with the possibility of reversible action on the closure belt. This may be, for example, closing with a tongue and groove joint. The closure according to the present invention comprises both a receptacle for closure for resealing the hole and an extension of the closure module to the first end portion, for example, to connect to the first end of the stopper.

In a preferred embodiment of the invention, it is provided that the closure module, in particular the closure belt, comprises at least a third stopper on a side facing the upper side of the lid surface, said stopper preferably corresponding essentially to the contour of the dispensing opening so that, due to the stopper the capping module can be connected or is connected, especially non-reversibly (with fixation) with a dispensing hole, while the capping belt to preferably partially or completely rests on the upper side of the surface of the cover with prestressing. The third stopper for the preferred non-reversible attachment (with fixation) of the closure element to the dispensing opening partially at the periphery is preferably a snap-lock ring connection or a snap-lock connection with a closure hook. Such limiter devices are known in the art. Typically, such devices, after fixing, cannot be removed without destruction.

In a particularly suitable embodiment, it is provided that the weakened profile surrounds the area for the dispensing hole except for the spacer section, especially near the first end part in the open and lateral position from the line formed by the fastening means and the first end part of the lever tongue in the open position. It has often been found to be preferable if, after the destruction of the reinforcing profile has begun, the area for the dispensing opening is not fully open, but remains connected to the surface of the lid via the aforementioned spacer section. In particular, if the lid of the container according to the invention is to be used to close the containers containing the beverage, it must be provided that the dispensing opening area does not fall into the beverage as a separated component after actuating the lever tab. It turned out to be preferable if this spacer section, which does not allow the possibility of falling of the separated zone for the dispensing hole, is located near the place where the first end part or the tip of the tongue of the lever tongue is used for the initial destruction of the reinforcing profile.

In particular, when using cover surfaces made of metal, for example, light metal, the surfaces of the covers are made, as a rule, with recessed and protruding parts in order to strengthen the structure of the cover.

Such structural elements are also known in the art in the form of so-called beads and can be structurally executed, for example, as rectilinear or curved.

In particular, such container lids have been found to be suitable according to the invention in which a partially or completely peripheral flange is located on the upper side of the surface of the lid, in particular close to the area for the dispensing opening. This collar is preferably a curved portion extending axially upward from the upper side of the lid surface.

According to another embodiment of the container lid, in accordance with the invention it is provided that the closure has at least one, in particular peripheral seal, which can be supported or which rests on the upper side of the surface of the lid, especially next to the dispensing opening. It is particularly preferable if the seal is hermetically interacting or can be brought, in particular, into hermetic interaction with the peripheral flange.

The container lid in the corresponding embodiment of the invention further comprises at least one recess on the upper side of the surface of the lid, said recess in the opening position of the lever tongue being overlapped at least partially by its second end part, and is located, in particular, laterally with offset from the line formed by the second end portion and the fastening means in the opening position. One at least a recess on the surface of the lid serves to facilitate the passage down and grab the second end part of the lever tongue to enable effective lifting of the lever tongue up in the region of the second end part, thereby pressing the first end part, i.e. the tip of the tongue, to the area overlapping of the dispensing hole. If the second end part of the lever tongue is especially close to the edge of the lid, which usually extends axially upward relative to the surface of the lid by a distance from the upper side of the surface of the lid, as a rule, there is little space left for possible raising the second end part of the lever tongue. This disadvantage in handling has been eliminated by the aforementioned recesses on the surface of the lid, which are designed to overlap with the second end portion of the lever tab. It is particularly preferred that the recesses are mirrored on opposite sides of a line extending from the second end portion to the first end portion at the opening. In this embodiment, the opening process is particularly suitable. It has also proven to be particularly suitable for alternatively or, in particular, additionally located grippers with a recess for the fingers, for example, in particular, rounded recesses in the second end part of the lever tongue, preferably in the area where in the opening position the lever tongue overlaps the recesses on the surface caps described above. This, in addition, contributes to the engagement, that is, the actuation of the lever tongue.

Particularly preferred are those embodiments of the container lid according to the invention in which the lever tongue comprises a holding element, in particular a metal locking tongue, by means of which the lever tongue, especially the first end portion of the lever tongue, is fixed to the surface of the lid by a fastening element. The holding member is typically located in the plane of the lever tongue or closure of the lever tongue, respectively. Preferably, it may be located, at least partially during the opening process, in a plane that differs from the plane of the closure during this process. While the first end of the retaining element usually faces or is connected to the first end portion of the lever tongue, at the opposite second end of the holding element there is usually a place for fixing means by which the lever tongue is attached to the surface of the lid.

If a closure belt is made of plastic, it turns out that it is especially practical to produce the end portion of the lever tongue by injection molding, preferably, the closure belt, at a portion of this first end portion, in conjunction with a holding element, in particular with a holding tongue. To this end, the end portion of the retaining element, in particular the retaining tab, also referred to as the first end of the retaining element, which is opposite the end portion, where the fastening means connects the retaining element, in particular the retaining tab, to the surface of the lid, also called the second end of the retaining element , is made by multicomponent molding with plastic by injection molding. Multicomponent molding of metal components or parts using an injection molding method is known to those skilled in the art.

Fixing devices for attaching the lever tongue to the surface of the lid by means of fastening means, for example, rivets, where it is also possible to use a holding element, for example, a holding tongue or bracket, such as, for example, which can be used for the lid of a container according to the invention, are known from the art and are described, for example, in DE 69302424T2, US 4148410, EP 564725 A1, WO 2007 / 048897A2, DE 10018685 C2, US 4887712, DE 8911286 U1 and DE 10261232 A1.

The present invention is based on the unexpectedly discovered fact that the lids of containers according to the invention, which for the first time provide reliable and tight re-closing of container systems equipped with so-called lever lids, for example, such as well-known beverage cans. In addition, this is particularly preferable with respect to container covers according to the invention, in which even non-metallic components, for example, plastic, can be used for their manufacture, the fluid filled in a container equipped with such a container cover is not exposed to such plastic materials in any way. during the filling process, neither during pasteurization, sterilization or any other stage of preservation or processing, which is likely to be performed, nor during the subsequent storage and transportation. In particular, under normal pasteurization conditions, during which temperatures between 50-70 ° C and pressures up to 7 bar are used, for reasons of food hygiene, it is advisable to avoid any contact with plastic parts that are not designed for such harsh conditions. Another advantage inherent in the lids of the containers according to the invention is the wide possibility of changes in the process of the final preparation of the fluid-filled containers according to the invention. It is even possible to attach the lever tab to the top surface of the lid only after the lids of the containers of the invention have been attached to the fluid-filled container body. Particular practicality has also been demonstrated in that the existing containers with container lids according to the invention can easily be configured so that they can be stacked on top of each other (in the stack), that is, in direct contact with each other. In addition, an advantage that is very significant from a market point of view is that the lid of the resealable container can easily be provided with a logo or a trade name or a trademark. Such a closure for an opening can be made in a separate process step and then connected to a lever tab to form a closure module.

Other features and advantages of the invention will become apparent from the description below, in which preferred embodiments of the invention are explained by way of example with reference to the schematic drawings, in which

1 a shows a container 1 according to the invention with a lid 2 of a container according to the invention and a container body 4. The lid 2 of the container contains a peripheral edge 6, which is hermetically connected to the container 4 by means of a suture connection 8. In addition, the lid 2 of the container is made with the surface 10 of the lid, on which there is a section 12 for the dispensing hole. The container lid further comprises a lever tab 14 with a first end portion 16 in the form of a tip of the tongue and with an opposite second end portion 18. The area 12 for the dispensing opening is limited by a weakened profile 20. In the embodiment of the invention shown in FIG. 1a, the lid 10 the cans or the dispensing zone 12 are made of light metal, for example aluminum. For mechanical hardening of the surface of the cover occupied by zone 12, a peripheral flange 22 is made in it. To harden the dispensing hole, a peripheral flange 25 is made adjacent to zone 12. The lever tab 14 in the embodiment of the invention shown in Fig. 1a is located in the so-called position for opening. Thus, the first end portion or tip 16 of the tongue is in a position with a partial overlap of the zone 12 for the dispensing hole. The lever tab 14 is connected to the surface 10 of the cover by means of a fastening means 24 in the form of a rivet. This connection is provided by means of a retaining tab or bracket 26, which extends from the fastening means 24 in the direction of the dispensing hole 12 and the mating portions to the first end portion 16.

By raising the second end portion 18 of the lever tab 14 to the opening position, the first end portion or tip 16 of the tongue is pressed against the overlapping area 12 for the dispensing hole. Thanks to the recesses 28 and 30 made on the lid surface 10, it is possible to grasp and lift the second end portion 18, and this is especially convenient also with container lids having a very small diameter (see figs. 1b and 1c). In the embodiment of the lid 2 of the container according to the invention shown in FIG. 1, in which the second end portion 18 of the lever tab 14 is very close to the edge 6, the user is actually forced to act correctly due to the location of the recesses 28 and 30 on the lid surface 10 on both sides of the axis passing between the first and second end parts 16, 18 in the opening position (see the dotted line in figa). If the lever tab 14 is in a position deviating from the opening position, the corresponding establishment of contact from below and the capture of the lever tab on the second end portion 18, as a rule, cannot be performed. In the present embodiment, manipulation of the lever tongue 14 on the second end portion 18 is further facilitated by the grip grooves 19 and 21 which, if the lever tongue is in the opening position, correspond to the location of the recesses 28 and 30, that is, the recess 19 for the grip is located above the recess 28, and the recess 21 to the grip is located above the recess 30. Thus, it becomes possible to raise without problems the lever tab on the second end portion 18, in particular, with the lids of containers having a small full diameter or such container covers, where the second end portion is very close to the edge 6. By lifting the lever element, as shown in Fig. 1b, the weakened profile 20 first collapses in only one place. If the lever tab 14 is pressed further down to the position shown in FIG. 1c, the softened profile 20 is almost completely torn to open or collapses. The separated portion for the dispensing opening is pushed into the container by interacting with the first end portion 16. That the softened profile is not provided completely peripheral, but instead an expansion section is provided (see also reference position 52 in FIG. 4), not containing the softened profile, this lid segment can be prevented from falling inside the container (other details are also indicated with respect to FIG. 5).

After the area 12 for the dispensing hole is opened, the lever tab 14 can be moved back to its original position with a horizontal orientation, as shown in fig.1d. Subsequently, the lever tab 14 can be translated into the closing position by rotation through 180 ° in the plane of the surface 10 of the cover (see figure 1). The second end portion 18 is in a position above the dispensing hole 12 (see Fig. 1f).

On the side of the second end portion 18, the lever tab 14 comprises a closure module 36 including a substantially peripheral closure belt 32 and an opening closure 34. In the illustrated embodiment, the reusable closure 34 is located on the inside of the closure. On the side facing the upper side of the lid surface 10, the closure flap 32 is configured so that the closure module 36, comprising the closure flap 32 and the closure 34 for the opening, can be forcibly inserted into the dispensing opening to provide a seal as shown in FIG. .

Figure 2 shows the image of the lid 2 of the container according to the invention. A closure module 36 comprising a closure 32 and a closure 34 for a hole is placed in the dispensing hole 12. A reusable closure 34 for the hole, made in the form of a hinged lid, is connected to the lever tab 14 or 32, respectively, by a hinge 38. Stops 42, 44, 46 and 48, protruding from the surface 10 of the cover, can also be seen in figure 2. The stops 42 and 44 prevent the lever tab 14 from turning through an angle of more than 180 ° and facilitate the correct installation of the closure module 36 in the closing position of the dispensing hole 12. The stops 46 and 48 are designed so that the lever tab 14 is capable of moving from the opening position to the closed position only in the direction of rotation (indicated by the arrow in FIG. 2).

Figures 3a and 3b show a container lid 2 according to the invention, in which the opening closure 34 is in the open position. As shown in FIG. 3b, the opening closure 34 can be rotated backward, that is, in the direction of the recesses 28 and 30, even further beyond the position shown in FIG. 3a. The closure 34 for the hole is preferably held in the opposite position by means of fixing or locking means. Thus, a free, without interference, the consumption of a drink from the container of FIG. 3 is provided. As shown in FIG. 3a, the opening closure 34 can be used again to close the lid 2 of the container. To ensure a particularly tight fit, the peripheral edge 35 of the closure 34 for the hole can be brought into tight contact with the inner edge 37 of the closure belt 32. Specialists in the art should be aware of the corresponding fastened, snap-fit or snap-fit fasteners, respectively.

4, a schematic top view of the lid 2 of the container according to the invention can be seen, however, without a lever tab. In the center of the lid surface 10 is a fastening means 24 for a lever tongue (not shown). On the periphery and near the weakened profile 20, the zone 12 for the dispensing hole contains a peripheral flange 22 with a bend up, which serves to strengthen the surface area formed by zone 12. Also next to the weakened profile 20 is a peripheral bead 50 with a bend up adjacent to the zone 12 on the surface 10 of the cover. As can be seen in FIG. 4, the softened profile 20 is structurally designed so as not to be completely peripheral. It is preferable to offset the spacer portion 52 laterally from axis AA. When manipulating the lever tab 14, the first end portion or tip 16 of the tongue, which, in the opening position, is connected to the overlap with the segment of the zone 12 for the dispensing hole, acts in the zone 12 next to this spacer section 52. When the first end part 16 is pressed on the zone 12 by means of the lever tongue 14, the weakened profile 20 is destroyed so that upon further action of the lever tongue, the entire area 12 is pushed into the container. The spacer portion 52 ensures that this zone does not become completely separated and cannot fall inside the container. Preferably, it is located in the interior of the container in the form of a segment of the lid surface turned inward.

5 is a schematic illustration of a component of the lever tab 14 with the closure 32 as part of the closure module 36. For clarity, the closure 34 for the hole and the retaining tab are not shown. In Fig. 5, you can see the side of the lever tab 14, which when used in a characteristic way facing the upper side of the surface 10 of the cover. The closure belt 32 on this side is provided with a peripheral seal 54. In the illustrated embodiment, the closure belt 32 extends into the first end portion 16 and also serves to strengthen the lever element. At this end portion 16, a retaining tab or retaining element (not shown) acts, which, together with the fastening means (not shown), provides attachment to the surface of the lid.

In Fig.6 you can see the lid of the container in cross section according to the invention. The closure belt 32 of the closure module 36 is inserted into the dispensing hole 12 by means of the gripping teeth 56 as part of the third retaining device 55. The peripheral seal 54 on the underside of the closure belt is supported by the seal on the peripheral shoulder 50. The closure 34 for the opening is installed inside the closure belt 32 In addition, the edge 8 with a seam forming the edge of the surface of the lid 2 can be seen in Fig.6. In addition, the attachment of the lever tab 14 to the surface 10 of the cover by means of the fastening means 24 can be seen in Fig.6. The fastening means 24, which is a rivet in the embodiment shown in FIG. 6, holds the rotationally supported holding member 26, while the first end 27 of said holding member is fused from plastic to the first end portion 16 of the lever tab 14. As shown in FIG. .6 in an embodiment of the invention, the closure flange 32 shown is connected to the retaining element only in a portion of the first end portion 16.

FIG. 7 shows, on an enlarged scale, part A of FIG. 6. The gasket 54, which interacts with the shoulder 50, is made with two elastic wedge-shaped ribs 58.60, which act on opposite sides from the top of the shoulder. In addition, the gasket 54 comprises sealing walls 62.64 adjacent to and at a distance from these sealing ribs that are in contact with the upper side of the cover surface 10. With the sealing element 54 shown in FIG. 7, a particularly effective hermetic insertion of the closure module 36 into the dispensing opening 12 is ensured. The locking of the gripping teeth 56 under the peripheral edge of the dispensing opening 12 is such that, in a locked or fixed state, as sealing ribs 58 and 60, and the sealing elements 62 and 64 of the walls are pressed peripherally to the upper side of the surface 10 of the cover. Such a seal contributes to a certain extent to the resealing of the container according to the present invention, which effectively prevents the escape of gases, for example carbon dioxide, from the container that has already been opened once.

On Fig you can see an enlarged schematic illustration of a segment B in section in Fig.6. Near the edge 11 of the lid surface 10, bounding the pouring zone 12 or the dispensing hole, on the surface of the lid is a peripheral flange 50 extending axially from the upper side of the lid surface 10. The capping module 36 is connected to the lid surface 10 by means of gripping teeth 56 without the possibility of reuse. In the closed position, the gripping teeth 56 of the third holding device 55 are pressed against the dispensing hole 12. This is largely due to the fact that the bevel surfaces 59 are made on the surface of the gripping teeth 56 facing the edge of the lid. When inserted with the force of the closure module 36 into the dispensing hole 12, these beveled surfaces are pressed against the edge 11. Preferably, the gripping teeth 56 or the third holding device 55 are made of relatively solid, but, however, spring material. Suitable plastic materials with such characteristics are known to those skilled in the art. The third holding device 55 may comprise, for example, two, three, four, five or even more gripping teeth 56 along the periphery of the edge 11 of the dispensing hole 12. In particular, if only a few gripping teeth are used, for example, two, three or four, then preferably to have them with an arrangement at approximately the same distance from each other and preferably not only to engage only the lower side of the lid surface 10, moreover pointwise, but also to be structurally executed with increased dimensions. Alternatively, it is also possible, as shown in FIG. 9, to create a third retaining device 55 around the periphery so that the gripping teeth 56 mesh or engage the lower side of the lid surface 10 along the edge 11 along the entire periphery of the dispensing opening 12. Once the edge 56 with the protrusion 61 is engaged with the edge 11 of the hole of the lower part of the lid surface 10, the closure module 36 is sealed in the pouring hole 12. The hermetic closure of the closure module 36 by means of a peripheral seal 54 which interacts with the upper side of the lid surface 10 is described in detail above with respect to FIG. In Fig. 8, in addition, it is possible to see the closure 34 for resealing the hole inserted into the closure belt 32, wherein said closure for the hole is hermetically connected to the inner wall of the closure belt 32, for example by means of peripheral protrusions 63 and 65.

Figure 9 shows a schematic top perspective view of an embodiment of a third holding device 55, which is ring-shaped and which is part of the closure 32 (not shown). Such a third peripheral holding device 55 contains a total of eight gripping teeth 56. The gripping teeth are made with rounded contact surfaces 59 and a gripping protruding portion 61, which is directed downward and engages with the lid surface 10 at the edge 11 in the same way (not shown ) In the presented embodiment, the corresponding gripping teeth are made with relatively large sizes and are separated only by narrow slots 67.

Features of the invention disclosed in the above description, in the claims and in the drawings, individually or in any combination, may be essential for the implementation of the invention in various embodiments of the invention.
