Description

Closing container lid, package, in particular beverage cans, containing the resealable container lid, method for manufacturing said container, as well as using the container lid according to the invention .

The present invention relates to a resealable container, a container, especially beverage cans, containing a resealable container lid, a method for manufacturing such containers and a container as well as the use of the container lid according to the invention.

Non-return containers for liquids have been used for a long time in multiple ways with the most diverse shapes and sizes. Especially frequent use is made of beverage cans made of light metal, in which the lid of the can is provided with a so-called crab closure. According to a first variant embodiment, the cover piece that forms the outlet opening in the direction towards the inside of the can is pressed by actuating this crab closure and is connected in an impermissible way with the can lid. According to another variant embodiment, in case of actuation of the crab closure, this closure is removed together with the area or the cover piece that forms the outlet opening. Closure systems of this type are described p. ex. in WO 97/030902, DE 100 18 685 C2, US 4,148,410, EP 564 725 A1, WO 2005 / 056400A1 and GB 2 379 917 A. When these closing systems have been activated once It is no longer essentially possible to effectively re-seal the packages with the lid piece pressed down or out. This is perceived as very disadvantageous, especially in very large beverage containers, since these, as a rule, after the first opening do not drink immediately until completely emptied. If, for example, these are soft drinks containing sugar containing gas, especially during the summer months, there is a danger of insects entering the container. In addition, they suffer the freshness, taste and quality of the drink, when stored without closing. Especially drinks that contain milk or yogurt, when they are subjected for a prolonged period of time to the surrounding air, permanently lose flavor and quality or become completely undrinkable. Closure systems that cannot be reprinted have been shown to be very especially disadvantageous in the case of beverage containers containing beverages containing carbon dioxide. Without proper closure, carbon dioxide escapes very quickly with the consequence that the beverage loses its characteristic flavor.

Therefore there have been no attempts to obtain beverage cans that can be closed again. A first solution proposal starts with can lids which contain from the beginning an outlet opening. The proposals that go in this direction are made known p. ex. in WO 2007/039367 A1, WO 2008/054636 A2, DE 20 2005 019 224 U1, US 3,952,911 and DE 601 01 995 T2. Containers of this type are, as a rule, especially for a prolonged period of time, approximately not as tight as p. ex. beverage cans, which are made from a can body and a can lid, which does not have a predetermined outlet opening. The manufacture of beverage containers of this type with predetermined outlet opening is generally very expensive in terms of material and work as well as in costs, if a high level of tightness is to be achieved, especially after re-sealing.

For beverage containers which do not have any outlet opening, systems that can be re-closed are achieved, according to another structure, because after the first opening process the lid or a part of the lid is provided with an additional cover. Systems of this type are disclosed in document DE 100 18 685 C2 and in DE 92 11 883 U1. Instead of providing a complete cover of the can lid, partial covers rotatably arranged on the can lid are also known. According to document DE 203 00 327 U1, a surface element can be moved, after an initial opening or breakage of an outlet opening on the surface of the lid, about a turning point on the lid surface, over the opening of exit. In WO 2005/056400 A1 use is made of a comparable closing mechanism. From WO 99/67150 A1 there is known a resealable can lid, in which the outlet opening is initially closed with a removable sheet, which is an integral part of the can lid . After the removal of this sheet, a closing cap can be inserted, connected by a film hinge with the lid of the can, flush with the outlet opening. The closure variant described in WO 99/67150 A1 is suitable for beverage caps made of plastic materials.

US Patent No. 4,887,712 refers to a beverage can whose outlet opening can be generated by a crab closure. The surface of the can lid that forms the outlet opening is pressed here in the direction of the inside of the can and is impermissibly connected to the can lid. The closing arc rotatably supported around a clamping point has a retention projection facing a recess, which corresponds to the contour of the exit opening and which, after rotation of the closing arc, can be introduced into it with the purpose of closing it. With this embodiment, a sufficient measure of tightness cannot be achieved, especially gas tightness. The closure system explained in GB 2 379 917 A corresponds essentially to that of US 4,887,712.

Document DE 89 11 286 U1 also shows a can lid with an opening tab that is rotatably supported on the wall of the lid. This swivel-supported opening tab has a closing element, which in the closed position is above the open exit opening and can

Crimp on it by closing it. The opening tongue is made of sheet metal, in one piece with the closing element.

WO 2004/056667 A1 discloses a beverage can closure in which the gripping tongue is formed to retract the outlet opening that has been formed by the breakage of a controlled breakage line. In this embodiment it is supported so that it can also rotate the tongue to grab so that it can rotate vertically around an axis disposed in the lid and the closure means is adapted, in terms of shape and size, to ensure a closure to a certain extent.

In DE 299 14 231 U1, a can lid that can be closed again is achieved thanks to the fact that the entire can lid is removed from the edge of the can, along a less sturdy stapled edge in the area of the pull tab. At the same time, the integrity of the can lid is not destroyed, so that after the use of the can, it can be placed again on the edge of the can.

To achieve closures of cans that can be closed again, which have a very high measure of tightness, it is necessary to integrate, according to DE 10 2005 057 755 A1 and DE 10 2005 004 759 A1, screw closures on the lid canned At the same time it can be planned p. ex. that a safety blade is destroyed by a first actuation of the screw closure.

From document DE 693 02 424 T2 a lid can be closed that can be re-closed in which on a pull tab or opening made of metal, which can be tilted around the clamping point, it can be pushed by slip a plastic bushing and can be fixed. The perimeter edges of this socket plugged over are structured in such a way that the outlet opening can be completely covered. In order that the pull tab rotatably supported with the plastic bushing attached above remains above the outlet opening, a groove is provided on the outer perimeter edge of the tongue, which engages in the perimetric beading edge of the can lid . In this way, although the position of the pull tab on the outlet opening is fixed, however, a large measure of tightness is not obtained.

From WO 2009/014409 A1 there is known a lid of a can of drink that can be closed again in which the opening tool and the closing of can of drink that can be closed again are arranged in one and the same hinge folding, present on the upper side of the cover surface. As soon as the opening tool has penetrated inside the can, after the stamping process of the opening area provided with a line of weakening not completely perimeter, only the lid closure can be moved over the common folding flap . This lid closure forms a unit component which can be folded in and out as such in the can opening.

EP 1 826 132 A1 refers to a resealable closure for beverage cans, which can be used as a separate component in a can opening that has been manufactured as a conventional lever tongue. This separate closure component has a basic part with an opening, which can be introduced into the can opening, as well as a movable closure piece along a hinged flap.

The cover variants that can be closed again known in the state of the art still suffer from disadvantages and leave unsatisfied desires, for example in terms of sealing in the case of drinks containing carbon dioxide. The closing systems that can be closed again known until now by the state of the art are not, as a rule, suitable to withstand with sufficient reliability the conditions of pasteurization in mass production, to which they are subjected regularly many drinks If the outlet or lid system does not allow pasteurization, in which temperatures in excess of 70 ºC and internal pressures of up to 7 bar generally reign, it is obliged to use preservatives.

To the extent that the systems known to the state of the art allow pasteurization, without the closing system that can be re-closed is affected, this happens frequently only because of the need to use plastic parts in the inner side of the can lid. With this, however, there is a risk that components of the plastic material used will access, in dissolved form, the pasteurized beverage.

The present invention therefore raised the problem of providing a resealable can of packaging, which does not show the disadvantages of the state of the art and which allows, in particular, a simple and reliable manufacturing also in case of production. en masse and that of place to beverage containers in which after a first opening and re-sealing the drink always keep, for a prolonged period of time, its original quality as well as, in the case of drinks with carbon dioxide , the original concentration of dissolved carbon dioxide.

Accordingly, a resealable container lid was found which comprises a lid surface with an upper and lower side, as well as with a perimeter edge and with an area for an outlet opening, delimited at least by a weakening profile that surrounds it totally or partially, characterized in that

it has a lever tongue rotatably held by means of fixing on the cover surface for opening, at least partially, of the area with the formation of the exit opening with a first end zone and a second end zone facing each other, the first end zone being able to be carried or being present in the opener position, at least partially, to overlap with a section of the area for the exit opening and the second end zone being present with respect to the first end zone beyond the fixing means, the lever tongue presenting in or next to the second end zone a closing module, comprising a neck or closing frame that can be supported or that rests on the upper side of the cover surface and which, in The closing position surrounds the dispensing opening, in particular, tightly when placed on the upper side of the cover surface and an opening closure that can be turned back to err, in particular surrounded by the closing neck.

By "opener position" it should be understood in the present invention that arrangement of the lever tongue on the cover surface on which the lever tongue can be actuated, to open the outlet opening. The closing position in the sense of the present invention should be understood as the arrangement of the lever tongue in which the closing module of the lever tongue is present above the outlet opening and can be connected or especially connected to it with the formation of a closure that can be closed again.

The cover surface may be manufactured, depending on the type of container, of plastic, metal, cardboard or cardboard or comprise respectively one or more of these materials. The same is true for the container body / container container. The cover surface in the sense of the present invention comprises a surface structure, for example a metal and / or plastic layer. Obviously, in the case of the lid surface of the container lid according to the invention, it can also be a multi-layered structure, comprising, for example, a metal lid surface, which has at least one sheet of material on the lower side. plastic as a protective layer.

The container lid according to the invention can be integral integral part or separate integral part of a container. In the latter case, the container lid and the container body or the container container may be fluid tightly connected to each other in a manner known to the person skilled in the art, e.g. ex. by adhesion or compression, for example by way of stapling. For example, the perimeter edge of the lid surface may also comprise a flange for connection to the package body. In the container lid according to the invention, in a preferred structure, the perimeter edge can have an extension which extends axially away from the upper side of the lid surface. At the same time it can be provided, in a suitable structuring, that the axial extension of the edge is formed such that the oversize of the extension is greater than the oversize of the extension of the lever tongue in axial extension with respect to the surface cover in the opener position, when the area for the exit opening is still intact. In particular, the last mentioned embodiment of a container lid according to the invention allows one to stack without problems one on other packages which are provided with such container covers.

A container body or container container within the meaning of the present invention comprises constructions both with and without background element. This responds to the fact that, for example, beverage cans made of metal are often manufactured with two or three parts. That is, in a two-part container, it is connected from a container body, which already has a bottom element, especially integral, with a container lid. In the case of a three-part container, it is factory made from a bottom element, a container wall and a container lid.

The resealable container lids of the present invention can be used for very different types of packages. As an example, drink cans for beverages containing carbon dioxide, milk bags, liquid yogurt container or fruit juice packaging can be mentioned. In addition to beverage containers, the container lid according to the invention can obviously also be used for packages in which liquid or powdery foods such as oil, vinegar or flour are offered. The container lids according to the invention are also taken into account for those packages with which body hygiene products such as shampoos or bath gels can be obtained on the market.

The shape and size of the area for the outlet opening in the lid surface can vary over wide margins and depends, as a rule, on the type of use in each case of the container that has been provided with the lid according to the invention. In a structuring it can be provided at the same time that the area for the outlet opening is distanced from the fixing means as well as, in particular, contiguous to the edge of the cover surface. The area for the exit opening is defined, in a suitable structuring by a completely or partially perimeter weakening profile. In the container lid according to the invention it is advantageous that as long as the area for the outlet opening remains intact, a liquid passage through the container lid becomes impossible, with a high degree of safety. Especially in beverage cans, a fluid-tight area of this type is called for the outlet opening, often notched plate as well as the weakening profile that limits or defines this area, also, notched profile.

The clamping means for the lever tabs of this type on the cover surface, as can be used

also with the container lid according to the invention, they are generally known. The lever tongue of the container lid according to the invention is designated in the state of the art, insofar as its opening mechanism is affected, also as crab closure. Especially in the opener position, the first end zone of the lever tongue overlaps, designated in many cases also as a retention projection, with the section of the area of the outlet opening. By means of an elevation of the second end zone of the lever lever, by means of lever action through the first end zone or through the retention projection, force is exerted on a section of the area of the outlet opening, which leads to that the weakening profile yields at or near the point of support of the force since the area of the lid surface, which previously covered the outlet opening, can be tilted in the direction of the interior of the container with the opening of The exit opening. The fixing means are preferably a rivet and is preferably located in the center of the cover surface. The fixing means can be fastened, especially depending on the size of the cover surface, especially also with respect to the size of the outlet opening, also at another point of the cover surface.

The second end zone of the lever tongue comprises a closing module, which is provided with a closing closure that can be closed again, for example in the form of a cover or a cover or cover lid. This cover can be connected, for example, by a hinge or a film hinge with the closure module, especially with the closure neck. The resealable opening closure has, in one embodiment, on its side oriented to the upper side of the cover surface, preferably, a first reversible immobilization unit which, by interaction with a second unit of Corresponding immobilization with this, provides a sealed opening closure in the closing neck that can be reversibly operated. Here it can be for example a slot / spring connection system. The closing neck in the sense of the present invention comprises both a housing element for an opening closure that can be closed again as well as the extension of the closing module to a first end zone, for example until the connection with the First end of the clamping element.

In a preferred embodiment it is provided that the closing module, especially the closing neck, present on the side facing the upper side of the cover surface, a third locking device, which essentially corresponds preferably to the contour of the area for the exit opening, so that by means of actuation of the immobilization device the closing module can be connected or is connected, especially irreversibly, with the exit opening, the closing neck being preferably, partially or totally , supported on the upper side of the cover surface under pretense. In the case of the third immobilization device for the preferably irreversible placement of the closure module in the outlet opening, it is preferably an annular enclosure or a retainer hook enclosure. Immobilization systems of this type are known to the state of the art. These systems cannot be removed as a rule again without destruction once the immobilization has been carried out.

In a particularly suitable structuring it is provided that the weakening profile surrounds the area for the exit opening except a distance zone, especially adjacent to the first end zone in the opener position as well as displaced laterally with respect to the line formed by the fixing means and the first end zone, in the opener position. It has been proven on multiple occasions as advantageous that, after the first breakage of the weakening profile, the area for the exit opening is not completely opened, but remains connected through the so-called distance zone with the surface of the lid . Especially when the container lid according to the invention closes containers containing drinks, it should be concerned that the area for the outlet opening, after actuation of the lever tongue, does not fall as a separate component inside the beverage . In this regard it has been shown to be advantageous that this distance zone, which prevents the fall of the separate area for the exit opening, is contiguous to the point at which the first end zone or the retention projection of the lever tongue with the purpose of the first destruction of the weakening profile.

Especially in the case of using metal cover surfaces, for example of light metal, recesses are made regularly in and out on the cover surface in order to reinforce the structure of the cover. Structures of this type are known to those skilled in the art as so-called grooves and can be formed, e.g. ex. rectilinear or arched.

In particular, the container lids according to the invention of this type have been shown to be suitable in which there is, in particular adjacent to the area for the outlet opening, a partially or completely perimeter groove on the upper side of the lid surface. In the case of this groove it is preferably a doming that extends axially upwardly from the upper side of the cover surface.

According to another embodiment of a container lid according to the invention, it is provided that the closure neck has at least one joint, especially perimeter, which can be brought into contact or is in contact with the upper side of the surface of the lid, especially adjacent to the outlet opening. At the same time it is especially advantageous if the joint interacts tightly or can be placed in a sealed interaction with the groove.

In a suitable structuring, the container lid according to the invention further comprises at least one recess on the upper side of the lid surface, which in the opener position of the lever tongue exhibits overlap, at least partially, with the second end zone thereof and which is arranged especially laterally offset with respect to the line formed in the opener position by the second end zone and the fixing means. Said at least one recess in the cover surface serves to facilitate the grip below the second end zone of the lever tongue, so as to be able to effectively drive the lever tongue up in the area of the second end zone, whereby the first end zone, that is to say that the retention projection is pressed against the overlapping area of the exit opening. If the second end zone of the lever tongue is especially close to the edge of the cover, which extends frequently with respect to the cover surface axially upwards from the upper side of the cover surface, it is generally as a rule little space to be able to raise the second end zone of the lever tongue. This handling deficit is remedied by providing for the recesses mentioned on the cover surface, which are arranged overlapping with the second end area of the lever tongue. In a particularly advantageous manner, recesses, preferably in specular arrangement, are arranged on different sides in a line, which extends from the second end zone to the first end zone in the opener position. In this variant embodiment, the opening process is particularly favorable. It has also proved especially advantageous to provide, alternatively or especially additionally, recessed grip handles, for example, in particular, rounded reliefs in the second end zone of the lever tongue, and preferably in an area in which in the opener position the lever tongue overlaps with the recesses, mentioned above, on the cover surface. This facilitates the manipulation again, that is to say the actuation of the lever tongue.

Especially preferred are embodiments such as these of the container lid according to the invention, in which the lever tongue has a clamping element, especially a metal clamping tongue, by means of which the lever tab it is, in particular, the first end zone of the lever tongue, fastened by means of fixing to the cover surface. The clamping element is, as a rule, present in the plane of the lever tongue or the closing neck of the lever tongue. Preferably it may be present, at least in parts during the opening process, in a plane, which differs in which the closing neck is present here. While the first end of the clamping element is, in general, oriented towards the first end end of the lever tongue or connected to it, it is present, at the second opposite end of the clamping element, as a rule, the point of positioning for the fixing means, with which the lever tongue is attached to the cover surface.

If it is planned to manufacture the closure neck with plastic, it has been shown as especially pragmatic, to inject the final area of the lever tongue, preferably the closure neck in the area of this first final zone in the clamping element, especially in the clamping tongue. In this case, this final section of the clamping element, especially of the clamping tongue, which is also called the first end of the clamping element, which is opposite the final section, in which the fixing means connect the fastener, especially the fastener, with the cover surface, also called the second end of the fastener. Overmolding of metal components or parts thereof with the help of the injection molding technique is known to the person skilled in the art.

The connection systems for the positioning of the lever tongue on the cover surface by means of fixing means, for example, a rivet, if necessary with the use of a fastener, for example, a fastener tongue or a clamping crossbar, such as those that can be used for the container lid according to the invention, are known from the prior art and are described, for example, in DE 693 02 424 T2, US 4,148,410, the EP 564 725 A1, WO 2007/048897 A2, DE 100 18 685 C2, US 4,887,712, DE 89 11 286 U1 and DE 102 61 232 A1.

According to the invention, a joint construction is also provided, which comprises an elastic joint body and, especially in contact with this elastic joint body, a joint base with a groove oriented in the direction of the elastic joint body with a edge and with branches extending from it in opposite directions, the elastic joint body being oriented towards the edge, in contact or being able to get in contact, through a first wedge-shaped elastic nerve and, distanced from it, a second rib, which narrows in the direction of the groove and in each case with each other in the opposite grooved branches, which extend away from the groove of the groove, as well as also disposing through a first joint wall, distanced from the first elastic nerve against the direction of the second nerve and a second joint wall, distanced the second elastic nerve from the direction of the primary er elastic nerve, which in each case are further distanced from the edge of the groove than the first or second elastic nerve and which are in contact with the joint base, when the elastic nerves are in contact with the grooves branches.

The present invention was based on the surprising discovery that container closures according to the invention are accessible which allow, for the first time, a reliable and sealed sealing of the packaging systems provided with so-called crab closures, such as those known For the cans of drinks. It is also especially advantageous, in relation to the container lids according to the invention, that although non-metallic components are used for their manufacture, for example plastics, the fluid introduced into the container provided with the container lid is not subjected to plastic materials of this type, neither during the filling process, nor during a pasteurization, sterilization step or other conservation or treatment step that should be carried out eventually, nor during subsequent storage or transport. In particular, under the usual pasteurization conditions, in which temperatures in the range of 50 to 70 ° C and pressures up to 7 bar are used, it is indicated, for reasons of food hygiene, to avoid any contact of parts of plastic, which are not subject to such strict conditions. Another advantage, which is produced with the container lids according to the invention, is the great processing variability during the manufacture of containers according to the invention filled with fluids. It is even imaginable that the lever tongue is attached, in the container body filled with fluid, to the surface of the lid. It has been shown that it is especially practicable that the packages that can be obtained with the container lids according to the invention are no longer arranged so that they can be stacked on top of one another, that is to say placed in direct contact with each other. An advantage, which should not be neglected by marketing aspects, is also based on the fact that the closing closure that can be re-closed from the lid according to the invention can be provided, in a particularly simple way and manner, with logos or names of brand. This opening closure can be manufactured in a separate manufacturing step and can then be introduced into the lever tab with the formation of the closure module.

or container body 4. The container cover 2 has a perimeter edge 6, which is connected, through a stapling connection 8, with the container container 4. The container lid 2 is also provided with a cover surface 10, in which there is an area 12 for the outlet opening. The container cover 2 also has a lever tongue 14 with a first end zone 16 in the form of a retaining boss and a second end zone 18 facing each other. The area for the outlet opening 12 is limited with a weakening profile 20. In the embodiment reproduced in Figure 1a) the can lid 10 or the area 12 for the outlet opening is made of a light metal, p. ex. aluminum. For the mechanical reinforcement of the cover surface covered by the area 12 a perimeter groove 22 is provided inside. For the reinforcement of the outlet opening, a perimeter groove 25 is provided adjacent to the area 12. The lever tongue 14 is, in the embodiment reproduced in Figure 1a), in the so-called opener position. This means that the first end zone or the retention projection 16 is in partial overlap with the area 12 for the exit opening. The lever tongue 14 is connected, through fixing means 24 in the form of a rivet, with the cover surface 10. This connection is achieved through a tongue or clamping rib 26, which extends from the means for fixing 24 in the direction of the area 12 for the exit opening and leading to the first end zone

16.

By raising the second end zone 18 of the lever tab 14 in the opener position, the first end zone or the retention boss 16 is pressed against the overlapped area of the area 12 for the exit opening. The second end zone 18 can be picked up and lifted (see Figures 1b) and 1c)) in a particularly comfortable way, thanks to the recesses 28 and 30 provided on the cover surface 10, also in the case of container lids with a very small diameter In the embodiment of a container lid 2 according to the invention reproduced in Figure 1, in which the second end zone 18 of the lever tongue 14 closely approximates the edge 6, the user is forced to make precisely a use suitable, thanks to the positioning of the recesses 28 and 30 on the cover surface 10, in each case on the sides of the shaft lying in the opener position through the first and second end zones 16, 18 (see the dashed line in Fig. 1a). If the lever tongue 14 is in a rotated position with respect to the opener position, it is not possible, as a general rule, to catch without problems under the lever tongue in the area of the second final zone 18. The operation of the lever tongue 14 in the second end zone 18 is provided in the embodiment shown again because the nail recesses 19 and 21 are provided which, when the lever tongue is in the opener position, corresponds to the position of the recesses 28 and 30, that is to say that the nail recess 19 is above the recess 28 and the nail recess 21 is above the recess 30. In this way it becomes possible, especially in container lids with a diameter small or in the container lids in which the second end zone comes very close to the edge 6, a smooth lifting of the lever tongue in the second end zone 18. By lifting the lever tongue, as shown In Figures 1b), the weakening profile 20 is destroyed, first, only at one point. When the tongue lever lever 14 is continued to be pressed down, to the position shown in Figure 1c), the weakening profile 20 is opened or almost completely destroyed. By interacting with the first end zone 16, the separate area for the outlet opening into the container is pressed inwards. Because the completely perimetral weakening profile has not been structured, but a distance zone is provided (see also reference sign 52 in Fig. 4), which does not have a weakening profile, it can be avoided that the segment of the stage falls into the interior of the package (details are given in this regard also for Figure 5).

Once the release of the area 12 for the exit opening has occurred, the lever tab 14 can be pushed back to the original horizontal orientation, as shown in Figure 1d). Then the lever tongue 14 can be moved, by a 180 ° rotation in the plane of the cover surface 10, to the closed position (see Figure 1e)). The second end zone 18 is then located above the outlet opening 12 (see Figure 1f)).

The lever tongue 14 disposes in the area of the second end zone 18 of a closure module 36, which comprises a closure neck 32, essentially perimetral, and an opening closure 34. The opening closure 34, which can be Acting reversibly, it is located, in the variant shown, in the closing neck. The closing neck 32 is structured in such a way, on the side facing the upper side of the cover surface 10, that the closing module 36, which comprises the closing neck 32 and the opening closure 34, can be introduced to pressure tightly in the outlet opening, as shown in Figure 1g).

Figure 2 shows a representation of the container lid 2 according to the invention. The closure module 36, which comprises the closure neck 32 and the opening closure 34, is housed in the outlet opening 12. The outlet opening 34 in the form of a flip-up lid, which can be operated reversibly, is connected by a hinge 38 with the lever tongue 14 or with the closure neck 32. From Figure 2, furthermore, the abutment points 42, 44, 46, and 48 protruding from the cover surface 10. The abutment points 42 are deduced. and 44 prevent rotation of the lever tongue 14 beyond an angle of 180 ° and facilitate the correct adjustment of the closure module 36 in the closed position on the outlet opening 12. The stop points 46 and 48 are responsible for that the lever tongue 14 can only be moved in a direction of rotation (indicated by the arrow in Figure 2) from the opener position to the closed position.

Figures 3a) and b) show a container lid 2 according to the invention, in which the opening closure 34 is in the open position. The opening closure 34 can be folded, beyond the position shown in Figure 3a), further back, that is in the direction of the recesses 28 and 30, as shown in Fig. 3b). Preferably, the opening closure 34 is reversibly held, by means of suitable locking or locking possibilities, in this open position. In this way it is possible to drink, in a particularly obstacle-free manner, liquid from the container shown in Figure 3. The opening closure 34 can, as indicated in Figure 3a), be reintroduced for closing the lid. of container 2. In order to achieve a particularly tight seal, the perimeter edge 35 of the opening closure 34 can be crimped in a sealed manner with the edge 37 located inside the closure neck 32. For the person skilled in the art they are well-known interlocking or encircling or tightening connections.

A schematic top view on a container lid 2 according to the invention is deduced from Figure 4, without lever tongue. In the center of the cover surface 10, fixing means 24 for the lever tongue (not shown) are located. The area 12 for the exit opening has, perimeter and contiguous to the weakening profile 20, a perimeter groove 22 domed upwards, which serves to reinforce the surface covered by the area 12. Also contiguous to the weakening profile 20 is located, adjacent to the area 12 on the cover surface 10, a groove 50 domed outwards. As shown in Figure 4, the weakening profile 20 is not completely perimetrically structured. Rather, it is displaced, a distance zone 52, laterally with respect to the A-A axis. Adjacent to this distance zone 52, it engages, when the lever tab 14, the first end zone or the retention projection 16 is operated, which in the opener position is in overlapping by sections with the area 12 for the outlet opening , in area 12. Thanks to the fact that by actuation of the lever tongue 14 the first end zone 16 is pressed against the area 12, the weakening profile 20 is broken so that when the lever tongue continues to be activated, the entire of area 12 is pressed into the container. The distance zone 52 takes care that this area is not completely separated and can fall into the container. Rather, it is present inside the package as a segment of the lid surface folded inwards.

Figure 5 shows, in schematic representation, a component of the lever tongue 14 with the closure neck 32 as an integral part of the closure module 36. For reasons of greater clarity, neither the opening closure 34 nor the tongue are shown. clamping In Figure 5, one looks at the side of the lever tongue 14 which, in case of generic use, is oriented towards the upper side of the cover surface 10. The closing neck 32 is provided, on this side, with a joint 54 perimeter. The closure neck 32 extends, in the variant shown, to the interior of the first end zone 16 and also serves to reinforce the lever tongue. In this final area 16, the clamping tongue or the clamping element (not shown) that carries out, with the fixing means (not shown), the connection to the cover surface.

Figure 6 shows a sectional view of a container lid according to the invention. The closing neck 32 of the closing module 36 is inserted, by means of retaining teeth 56 as an integral part of the third retention 55, into the outlet opening 12. The perimeter seal 54 on the lower side of the closing neck 32 comes into contact , tightly, on the perimeter groove 50. Opening closure 34 is inserted in the closure neck

32. Figure 6 also shows the stapling 8 that forms the edge of the cover surface 2. Furthermore, the connection of the lever tongue 14 is deduced from Fig. 6, through the fixing means 24, on the surface

of cover 10. The fixing means 54, which in the embodiment shown in Fig. 6 is a rivet, fasten so that they can rotate the fastener 26, whose first end 27 is overmoulded with the plastic material of the first end zone 16 of the lever tongue 14. As shown in Fig. 6, in the embodiment shown, the closure neck 32 is connected only in the area of the first end zone 16 with the fastener.

Figure 7 shows an enlargement of the section in detail A of Figure 6. The joint 54, which interacts with the groove 50, is formed with two wedge-shaped ribs 58, 60, which engage on opposite sides of the reverse of the groove. The joint 54 also has joint walls 62, 64, present adjacent and spaced apart from these joint ribs, which are in contact with the upper side of the cover surface 18. By means of the joint construction 54 represented in the Figure 7 achieves an especially effective fluid-tight introduction of the closure module 36 in the outlet opening 12. The interlocking of the locking hook 56 below the perimeter edge of the outlet opening 12 is adjusted at the same time in such a manner. that in the locked or immobilized state both the joint ribs 58 and 60 as well as the joint wall elements 62 and 64 are compressed, perimetrically, against the upper side of the cover surface 10. This joint contributes in a manner not irrelevant to a container closure that can be resealed in the sense of the present invention, which effectively prevents the escape of gases from the open container with suede priority, for example carbon dioxide.

From Fig. 8 an enlarged schematic section view of section B according to Fig. 6 follows. Adjacent to the edge 11 of the cover surface 10, which limits the exit area or the outlet opening 12, is located in the cover surface of the perimeter groove 50 extending axially away from the upper side of the cover surface 10. The closing module 36 is irreversibly connected to the cover surface by means of retaining teeth 56. The teeth 10. of retention 56 of the third immobilization device 55 have been pressurized into the outlet opening 12 in the closed position. This is especially well achieved because of the surface of the retaining teeth 56 facing the edge of the lid, chamfered surfaces 59 are provided. These chamfered surfaces are pressed, during the pressure introduction of the closure module 36 into the outlet opening 12, pressed against the edge 11. At the same time it is advantageous that the retaining teeth 56 or that the third immobilization device 55 is made of a relatively rigid material, although at the same time still always elastic. Suitable plastic materials are known to those skilled in the art that exhibit these properties. The third immobilization device 55 may have, e.g. eg, two, three, four, five or even more retaining teeth 56 arranged perimetrically along the edge 11 of the outlet opening 12. Especially when only a few retaining teeth are used, for example two, three or four, it is advantageous that these are arranged approximately equal to each other and that they preferably do not take the cover surface 10 in a timely manner from below, but are made wider. Alternatively, it is also possible, as shown in Fig. 9, to structure the third immobilization device 55 perimetrically, so that the retaining teeth 56 encompass or catch, along the entire perimeter of the opening outlet 12, the lid opening 10 along the edge 11 below. As soon as the edge 56 with the shoulder 61 is interlocked below the cover surface 10 at the opening edge 11, the closure module 36 is tightly crimped in the outlet opening 12. The sealing edge of the closure module 36 by the perimetral joint 54, which interacts with the upper side of the cover surface 10, has already been described sufficiently in detail for Fig. 7. From Fig. 8 an opening closure 34 can also be deduced that can be recessed recessed in the closure neck 32, which is present in a sealed manner in the inner wall of the closure neck 32, for example by perimetral thickening 63 and 65.

Fig. 9 shows, in schematic perspective top view, an embodiment of the third immobilization device 55, which is structured perimetrically and constitutes an integral part of the closure neck 32 (not shown). This third immobilization device 55 has a total of eight retention teeth 56 perimeter. The retention teeth are provided with a printed contact surface 59 as well as with an interlocking shoulder 61, which takes the cover surface 10 by below by the edge 11 thereof (not shown). The corresponding retention teeth are structured relatively wide in the variant shown and are separated from each other only by narrow incisions 67.
