Abstract

: \sht\Interwovn\NRPortbl\DCC\SBT\5062930_I.DOC-I0 04/2013 - 29 Abstract The present invention relates to a reclosable container lid, comprising a lid surface having an upper side and a lower side and having a circumferential edge and a zone for a dispensing aperture, delimited by at least one entirely or partially circumferential 5 weakening profile, a lever tab, being pivotably fastened to the lid surface via a fastening means, for at least partly opening the zone in a manner forming the dispensing aperture, having a first end portion and an opposite second end portion, wherein the first end portion, in the opener position, can be brought to or is in a position so as to at least partly overlap with a section of the zone for the dispensing aperture and wherein the second end 10 portion is present on the other side of the fastening means in relation to the first end portion, wherein the lever tab has a closure module at or adjacent to the second end portion, said closure module comprising a closure collar which can be brought to rest or which rests against the upper side of the lid surface and which, in the closure position, extends along the dispensing aperture, particularly in a sealing manner, when being placed 15 on the upper side of the lid surface, and, particularly framed by the closure collar, a reclosable aperture closure. Moreover, the invention relates to a container, comprising this container lid, a method of manufacturing such containers and the use of the container lids of the invention.

Description

:\ sht\Interwovn\NRPortbl\DCC\SBT\5062930_I.DOC-10 04/2013 Reclosable container lid, containers, particularly beverage cans, containing said reclosable container lid, methods of manufacturing such containers and use of said container lid This application claims divisional status from Australian Patent Application No. 2011281959, the disclosure of which is incorporated herein by reference. 5 Description The present invention relates to a reclosable container lid, containers, particularly beverage cans, containing the reclosable container lid, methods of manufacturing such containers and the use of the container lid of the invention. Non-returnable containers for liquids have been widely used in a variety of different 10 shapes and sizes for quite some time now. Particularly frequently light-metal beverage cans are used, where the can lid is equipped with a so-called lever closure. According to a first embodiment variant, the lid piece forming the dispensing aperture is pushed in the direction of the can interior by operating this lever closure and remains undetachably connected to the can lid. According to a further embodiment variant, the lever closure, 15 together with the zone or lid piece forming the dispensing aperture, is removed when operating the lever closure. Such closure systems are described, for example, in WO 97/030902, DE 100 18 685 C2, US 4,148,410, EP 564 725 Al, WO 2005/056400 Al and GB 2 379 917 A. Once these closure systems have been operated, an effective reclosing of the containers with the lid piece pushed down or out is basically no longer possible. This is 20 perceived as very disadvantageous, particularly with larger beverage receptacles, as these usually are not consumed completely immediately after initial opening. If the beverage in question is a sugar-containing soft drink, for example, there is a risk of insects entering the container, particularly during the summer months. Moreover, the freshness, taste and quality of the beverage are adversely affected if the beverage is kept in an unclosed 25 condition. Particularly beverages containing milk or yogurt will permanently lose their taste and quality or will even become completely inedible if they are exposed to ambient air for a longer period of time. The non-reclosable closure systems of beverage receptacles containing carbonated beverages have shown to be particularly disadvantageous. Without a :\ sht\Interwovn\NRPortbl\DCC\SBT\5062930_I.DOC-10 04/2013 -2 suitable closure, the carbon dioxide escapes very quickly, resulting in the beverage losing its characteristic taste. There has been no lack of attempts, therefore, to achieve reclosable beverage cans. A first approach starts out from can lids which contain a dispensing aperture right from the 5 beginning. Proposals in this direction are disclosed, for example, in WO 2007/039367 Al, WO 2008/054636 A2, DE 20 2005 019 224 Ul, US 3,952,911 and DE 601 01 995 T2. As a rule, however, such containers are not nearly as tight, especially over a longer period of time, as, for example, beverage cans made of a can body and a can lid not having a predefined dispensing aperture. Also, the manufacture of such beverage receptacles having 10 a predefined dispensing aperture in most cases requires a very high material and labour input and is very cost-intensive if a high degree of tightness, particularly also after reclosing, is to be achieved. For beverage receptacles not having a predefined dispensing aperture, reclosable systems are achieved according to a further realisation by the lid or a part of the lid being provided 15 with an additional cover after the first opening procedure. Such systems are disclosed, for example, in DE 100 18 685 C2 and DE 92 11 883 Ul. Instead of providing a complete cover of the can lid, also partial covers being pivotably attached on the can lid are known. According to DE 203 00 327 Ul, after initial breaking-open or tearing-open of a dispensing aperture, a planar element may be pivoted about a pivot point on the lid surface 20 to a position over the dispensing aperture. A comparable closure mechanism is used in WO 2005/056400 Al. From WO 99/67150 Al a reclosable can lid is known in which the dispensing aperture is initially closed off with a removable film which is an integral part of the can lid. After removing this film, a closure cap being connected to the can lid via a film hinge may be inserted flush into the dispensing aperture. The closure variant described in 25 WO 99/67150 Al is suitable for can lids made of plastic materials. US 4,887,712 deals with a beverage can, the dispensing aperture of which may be created via a lever closure. Here, the surface of the can lid forming the dispensing aperture is pushed in the direction of the can interior and is undetachably connected to the can lid. The closure member, which is supported in a manner pivotable about a fastening point, has a :\ sht\Interwovn\NRPortbl\DCC\SBT\5062930_I.DOC-10 04/2013 -3 dished region opposite the tab nose, which corresponds to the contour of the dispensing aperture and which may be inserted into it after pivoting the closure member for the purpose of closing. A sufficient degree of tightness, in particular gas-tightness, cannot be achieved with this embodiment. The closure system explained in GB 2 379 917 A 5 substantially corresponds to the one of US 4,887,712. Also from DE 89 11 286 Ul a can lid is apparent, having a tear-open tab pivotably supported on the lid wall. This pivotably supported tear-open tab has a closure element, which, in the closing position, is present over the opened dispensing aperture and may closingly engage it. The tear-open tab and the closure element are formed from sheet metal 10 as a single piece. WO 2004/056667 Al discloses a beverage can closure in which the gripping portion of the tab is designed for reclosing the dispensing aperture created by breaking open a predetermined breaking line. Also in this embodiment, the gripping portion of the tab is supported in a manner pivotable about an axis located in the lid so as to be vertically 15 pivotable, and the shape and size of the closure means are adapted to the dispensing aperture so as to ensure reasonably tight closure. In DE 299 14 231 Ul a reclosable can lid is achieved by removing the entire can lid from the can rim via a seamed edge which is less stable in the region of the pull tab. The integrity of the can lid is not destroyed in this manner, so that the can lid may be placed 20 back on the can rim after the can has been used. To achieve reclosable can closures having a higher degree of tightness, according to DE 10 2005 057 755 A and DE 10 2005 004 759 Al, threaded closures are to be integrated into the can lid. It may be provided, for example, that a safety film is destroyed on initial operation of the threaded closure. 25 From DE 693 02 424 T2 a reclosable can lid closure is apparent, where a plastic sleeve may be slipped over a metal pull or tear-open tab, said tab being pivotable about a fastening point, and fixed thereto by clamping. The peripheral edges of this slipped-over sleeve are realised such that the dispensing aperture may be covered completely. In order H:\ ht\Interwoven\NRPortbl\DCC\SBT\5062930_l.DOC-l0 04/2013 -4 for the pivotably supported pull tab with its slipped-over plastic sleeve to remain over the dispensing aperture, a groove is provided at the outer peripheral edge of the tab, said groove lockingly engaging the peripheral curled edge of the can lid. In this manner, the position of the pull tab over the dispensing aperture is fixed, but a particularly high degree 5 of tightness is not accomplished thereby. The reclosable lid variants known from the art still have their disadvantages and leave room for improvement, for example with regard to the tightness in the case of carbonated beverages. Moreover, the reclosable lid systems known from the art so far are usually not suitable to resist with sufficient reliability the pasteurisation conditions during mass 10 production, which many beverages have to be subjected to as a rule. If the dispensing or lid system does not allow pasteurisation, during which generally temperatures above 70 'C and internal pressures of up to 7 bars occur, it is inevitable to resort to the use of preservatives. Insofar as the systems known from the art allow pasteurisation to be performed at all 15 without the reclosable closure system provided being affected, this is often achieved only by having to use plastic elements on the inner side of the can lid. This entails the risk, however, of components of the plastic materials used entering the pasteurised beverage in a dissolved form. The object of the present invention was therefore to provide a reclosable container lid 20 which does not have the disadvantages of the prior art and which in particular allows easy and reliable manufacturing also in the environment of mass production and leads to beverage receptacles in which the beverage continues to maintain its original quality and, in the case of carbonated beverages, the original concentration of dissolved carbon dioxide over a longer period of time after initial opening and reclosing. 25 Accordingly, a reclosable container lid has been found, comprising a lid surface having an upper and a lower side and having a circumferential edge and a zone for a dispensing aperture, delimited by at least one entirely or partially circumferential weakening profile, a lever tab, being pivotably fastened to the lid surface via a fastening means, for at least :\ sht\Interwovn\NRPortbl\DCC\SBT\5062930_I.DOC-10 04/2013 -5 partly opening the zone in a manner forming the dispensing aperture, having a first end portion and an opposite second end portion, wherein the first end portion, in the opener position, can be brought to or is in a position so as to at least partly overlap with a section of the zone for the dispensing aperture and wherein the second end portion is present on 5 the other side of the fastening means in relation to the first end portion, wherein the lever tab has a closure module at or adjacent to the second end portion, said closure module comprising a closure collar or frame which can be brought to rest or which rests against the upper side of the lid surface and which, in the closure position, extends along the dispensing aperture, particularly in a sealing manner, when being placed on the upper side 10 of the lid surface, and, particularly framed by the closure collar, a reclosable aperture closure. Opener position in terms of the present invention is to be understood as the orientation of the lever tab on the lid surface in which the lever tab may be operated so as to uncover the zone for the dispensing aperture. Closure position in terms of the present invention is to be 15 understood as the orientation of the lever tab in which the closure module of the lever tab is in a position over the dispensing aperture and can be, or in particular is, connected to said aperture in a manner forming a reclosable closure. Depending on the container type, the lid surface may be manufactured from plastic, metal, or paperboard or cardboard, respectively, or comprise one or several of these materials. 20 The same applies to the container body/container receptacle. Lid surface in terms of the present invention comprises a planar structure, for example a metal and/or plastic layer. Naturally, the lid surface of the container lid of the invention may also be a multilayer structure, comprising, for example, a metal lid surface having on the lower side at least one plastic film as a protective layer. 25 The container lid of the invention may be an integral part or a separate part of a container. In the latter case the container lid and container body or container receptacle may be connected to each other in a liquid-tight manner familiar to those skilled in the art, e.g. by gluing or pressing, for example by a seam. For example, the circumferential edge of the lid surface may also comprise a flange for connection to the container body. With the : sbt\Interwoven\NRPortbl\DCC\SBT\5062930_l.DOC-l0 04/2013 -6 container lid of the invention, the circumferential edge in a preferred realisation may have an expansion extending axially away from the upper side of the lid surface. In a convenient realisation it may be provided that the axial extension of the edge is formed such that the extent of the expansion is greater than the extent of the expansion of the lever tab in an 5 axial extension in relation to the lid surface in the opener position when the zone for the dispensing aperture is still intact. Particularly the latter embodiment of a container lid of the invention allows containers equipped with such container lids to be stacked on top of each other without any problems. A container body or receptacle in terms of the present invention comprises constructions 10 with and without a bottom element. This is due to the fact that, for example, metal beverage cans are often manufactured as two or three pieces. That is, in the case of a two piece container, said container is joined from a container body already having a bottom element, particularly an integral one, and a container lid. In the case of a three-piece container, said container is manufactured from a bottom element, a receptacle wall and a 15 container lid. The reclosable container lids of the present invention may be used for a variety of container types. Some examples include beverage cans, e.g. for carbonated beverages, milk cartons, (liquid) yogurt receptacles or packings for fruit juices. Apart from containers for beverages, the container lid of the invention may of course also be used for containers in 20 which liquid or powdery foodstuffs such as oil, vinegar or flour are offered. The container lids of the invention are also suitable for containers in which personal hygiene products such as shampoos or shower gels are available on the market. The shape and size of the zone for the dispensing aperture in the lid surface may vary to a large degree and usually depend on the respective type of use of the container with which 25 the lid of the invention is provided. In one realisation it may be provided that the zone for the dispensing aperture is spaced at a distance from the fastening means and in particular is adjacent to the edge of the lid surface. In a convenient realisation the zone for the dispensing aperture is defined by an entirely or partially circumferential weakening profile. The container lids of the invention are advantageous in that, as long as the zone for the H:\ ht\Interwoven\NRPortbl\DCC\SBT\5062930_l.DOC-l0 04/2013 -7 dispensing aperture has remained intact, penetration of liquid through the container lid is rendered impossible with a maximum degree of security. Particularly in the context of beverage cans such a fluid-tight zone for the dispensing aperture is often also referred to as a score panel and the weakening profile adjoining or defining this zone is referred to as a 5 score profile. Fastening means for such lever tabs on the lid surface, such as may be used also with the container lid of the invention, are generally known. As far as its opening mechanism is concerned, the lever tab of the container lid is also referred to in the art as a lever closure. Particularly in the opener position, the first end portion of the lever tap, frequently also 10 referred to as a tab nose, overlaps with a section of the zone for the dispensing aperture. By lifting the second end portion of the lever tab a force is applied to a section of the zone of the dispensing aperture via the first end portion, or via the tab nose, by means of the lever action, leading to a fracturing of the weakening profile at or adjacent to the force application point, and to the zone of the lid surface previously covering the dispensing 15 aperture being pivotable in the direction of the container interior while at the same time uncovering the dispensing aperture. The fastening means preferably is a rivet and preferably is in the centre of the lid surface. Depending particularly on the size of the lid surface, especially also relative to the size of the dispensing aperture, the fastening means may also be fastened at a different position on the lid surface. 20 The second end portion of the lever tab comprises a closure module which is equipped with a reclosable aperture closure, for example in the form of a flap or lid flap. This flap may, for example, be connected to the closure module, in particular the closure collar, via a hinge or a film hinge. The reclosable aperture closure in one embodiment on its side facing the upper side of the lid surface has a reversible first arresting unit which, in interaction 25 with a corresponding second arresting unit, provides a tight and reversibly operable aperture closure at the closure collar. This may be, for example, a groove/tongue connection system. The closure collar in terms of the present invention comprises both a receiving element for the reclosable aperture closure and the extension of the closure module up to the first end portion, for example up to the affixing to the first end of the 30 retention element.
: sbt\Interwoven\NRPortbl\DCC\SBT\5062930_l.DOC-l0 04/2013 -8 In a preferred embodiment it is provided that the closure module, particularly the closure collar, has at least a third arresting device on the side facing the upper side of the lid surface, said arresting device preferably substantially corresponding to the contour of the zone for the dispensing aperture, such that by operating the arresting device the closure 5 module can be or is connected, particularly irreversibly, to the dispensing aperture, wherein preferably the closure collar, partially or entirely, rests against the upper side of the lid surface under prestress. The third arresting device for a preferably irreversible attachment of the closure module to the dispensing aperture is advantageously a, particularly circumferential, ring snap connection or a locking hook snap connection. Such 10 arresting device systems are known from the art. Usually, these systems cannot be removed in a non-destructive manner after arresting has occurred. In a particularly convenient realisation it is provided that the weakening profile surrounds the zone for the dispensing aperture except for a distance region, in particular adjacent to the first end portion in the opener position and laterally offset from the line formed by the 15 fastening means and the first end portion of the lever tab in the opener position. It has often shown to be advantageous if, after the initial breaking-open of the weakening profile, the zone for the dispensing aperture is not uncovered completely, but remains connected to the lid surface via the above-mentioned distance region. Particularly if the container lid of the invention is to be used for closing containers containing beverages, it should be ensured 20 that the zone for the dispensing aperture does not fall into the beverage as a separate component after operating the lever tab. It has shown to be beneficial if this distance region, which prevents the separated zone for the dispensing aperture from falling in, is adjacent to the point where the first end portion or the tab nose of the lever tab is applied for the purpose of initial destruction of the weakening profile. 25 Particularly when using lid surfaces of metal, for example light metal, recessed and raised portions are worked into the lid surface as a rule for the purpose of stiffening the lid structure. Such structures are also known in the art as so-called beads and may be designed, for example, as a straight line or curved.
:\ sht\Interwovn\NRPortbl\DCC\SBT\5062930_I.DOC-I0 04/2013 -9 Particularly such container lids of the invention have shown to be convenient in which a partially or entirely circumferential bead is present on the upper side of the lid surface, particularly adjacent to the zone for the dispensing aperture. Preferably this bead is an arched portion extending axially upwards from the upper side of the lid surface. 5 According to a further embodiment of a container lid of the invention, it is provided that the closure collar has at least one, particularly circumferential, seal, which can be brought to rest or which rests against the upper side of the lid surface, particularly adjacent to the dispensing aperture. It is particularly advantageous if the seal sealingly interacts or can be brought into sealing interaction with the particularly circumferential bead. 10 In a convenient realisation the container lid of the invention further comprises at least one recess on the upper side of the lid surface, said recess in the opener position of the lever tab overlapping with the second end portion thereof at least partially and being particularly arranged laterally offset from the line formed by the second end portion and the fastening means in the opening position. The at least one recess in the lid surface serves to facilitate 15 reaching underneath and gripping the second end portion of the lever tab so as to be able to effectively raise the lever tab upwardly in the region of the second end portion, thus pressing the first end portion, i.e. the tab nose, against the overlapping area of the dispensing aperture. If the second end portion of the lever tab is particularly close to the lid edge, which often extends axially upwards relative to the lid surface, away from the upper 20 side of the lid surface, there is, as a rule, little room left to be able to lift the second end portion of the lever tab. This shortcoming in handling is remedied by providing the above mentioned recesses in the lid surface, which are arranged so as to overlap with the second end portion of the lever tab. Particularly advantageously recesses are provided, preferably in a mirror-inverted arrangement, on different sides of a line extending from the second 25 end portion to the first end portion in the opener location. With this embodiment variant, the opening process proceeds particularly conveniently. It has also shown to be particularly advantageous to provide alternatively or, in particular, additionally recessed finger grips, for example, in particular rounded, indentations in the second end portion of the lever tab, preferably in an area where, in the opener position, the lever tab overlaps with the recesses :\ sht\Interwovn\NRPortbl\DCC\SBT\5062930_I.DOC-I0 04/2013 - 10 in the lid surface described above. This further facilitates the engagement, i.e. the operation of the lever tab. Particularly preferred are those embodiments of the container lid of the invention in which the lever tab has a retention element, particularly a metal retention tongue, via which the 5 lever tab, particularly the first end portion of the lever tab, is fastened to the lid surface by means of the fastening means. As a rule, the retention element is present in the plane of the lever tab or of the closure collar of the lever tab, respectively. Preferably it may be present, at least in parts during the opening process in a plane which differs from the plane of the closure collar during this process. While the first end of the retention element generally 10 faces the first end portion of the lever tab or is connected thereto, at the opposite second end of the retention element there is usually the attachment location for the fastening means with which the lever tab is fastened to the lid surface. If it is provided to manufacture the closure collar from plastic, it has shown to be particularly pragmatic to injection-mould the end portion of the lever tab, preferably the 15 closure collar in the region of this first end portion, to the retention element, in particular the retention tongue. For this purpose, the end section of the retention element, in particular of the retention tongue, also referred to as the first end of the retention element, which is opposite the end portion where the fastening means connects the retention element, in particular the retention tongue, to the lid surface, also referred to as the second 20 end of the retention element, is overmoulded with a plastic material. Overmoulding of metal components or parts thereof using the injection-moulding technique is known to those skilled in the art. Affixing systems for attaching the lever tab to the lid surface by means of a fastening means, e.g. a rivet, where applicable also using a retention element, e.g. a retention tongue 25 or retention strut, such as may be used for the container lid of the invention, are known from the art and are described, for example, in DE 693 02 424 T2, US 4,148,410, EP 564 725 Al, WO 2007/048897 A2, DE 100 18 685 C2, US 4,887,712, DE 89 11 286 Ul and DE 102 61 232 Al.
:\ sht\Interwovn\NRPortbl\DCC\SBT\5062930_I.DOC-I0 04/2013 - 11 The object of the invention is further achieved by a container comprising a container body or container receptacle and a container lid of the invention. Any fluid may be accommodated in these containers.

According to the invention a sealing construction is further provided comprising an elastic sealing body and, particularly resting against this elastic sealing body, a seal support having a bead with a crest, said bead facing in the direction of the elastic sealing body, and 15 shoulders extending in opposite directions therefrom, wherein the elastic sealing body, facing the bead, has a first and, spaced apart therefrom, a second wedge-shaped elastic rib, which taper in the direction of the bead and which each rest or can be brought to rest against opposite bead shoulders extending away from the crest of the bead, and further a first sealing wall, spaced from the first elastic rib opposite to the direction of the second 20 rib, and a second sealing wall, spaced from the second elastic rib opposite to the direction of the first rib, each being spaced at a greater distance from the crest of the bead than the first and second elastic rib, respectively, and resting against the seal support if the elastic ribs rest against the bead shoulders. The present invention is based on the surprising finding that container closures of the 25 invention are available which, for the first time, permit a reliable and tight reclosure of container systems provided with so-called lever closures, such as known from beverage cans. It is further particularly advantageous in the context of the container lids of the H:\ ht\Interwoven\NRPortbl\DCC\SBT\5062930_l.DOC-l0 04/2013 - 15 invention that, even though non-metallic components may be used for their manufacture, for example plastics, the fluid filled into the container provided with this container lid is subjected to such plastic materials neither during the filling process nor during a pasteurisation, sterilisation or any other preservation or treatment step which may have to 5 be performed and also not during subsequent storage and transport. Particularly under the usual pasteurisation conditions, during which temperatures ranging from 50 to 70 'C and pressures of up to 7 bars are applied, it is advisable for reasons of food hygiene to avoid any contact with plastic parts which are not designed for such harsh conditions. A further advantage coming along with the container lids of the invention is the great process 10 variability in the finishing of fluid-filled containers of the invention. It is even conceivable to fasten the lever tab to the top surface of the lid only after the container lids of the invention have been attached to the fluid-filled container body. It has also shown to be particularly practical that the containers available with the container lids of the invention can be readily configured such that they can be stacked on top of each other, i.e. being in 15 direct contact with each other. Furthermore, an advantage which is quite significant from a marketing point of view is that the reclosable container lid may be provided with logos or brand names in a particularly easy manner. This aperture closure may be manufactured in a separate manufacturing step and is subsequently to be integrated into the lever tab in a manner forming the closure module. 20 Further features and advantages of the invention will become apparent from the description below, in which preferred embodiments of the invention will be explained by way of example with reference to schematic drawings, in which Figures 1 a) to g) show a container lid of the invention and a container of the invention, respectively, in different stages of use; 25 Figure 2 shows a container lid of the invention with a closed aperture closure; Figures 3a) and b) show a container lid of the invention with an opened aperture closure; Figure 4 shows a schematic top view of a container lid of the invention without the lever tab; :\ sht\Interwovn\NRPortbl\DCC\SBT\5062930_I.DOC-10 04/2013 - 16 Figure 5 shows a schematic perspective top view of the lower side of the closure collar of the lever tab; Figure 6 shows a container lid of the invention in a cross-sectional view; Figure 7 shows an enlargement of section A of Figure 6; 5 Figure 8 shows an enlarged representation of section B of Figure 6; and Figure 9 shows a schematic perspective view of an embodiment of a third arresting device of a container lid of the invention. Figure la) shows a container 1 of the invention with a container lid 2 of the invention and a container receptacle or body 4. The container lid 2 has a circumferential edge 6 which is 10 connected to the container receptacle 4 in a fluid-tight manner via a seam connection 8. Moreover, the container lid 2 is equipped with a lid surface 10 in which there is a zone 12 for a dispensing aperture. The container lid 2 furthermore has a lever tab 14 having a first end portion 16 in the form of a tab nose and an opposite second end portion 18. The zone for the dispensing aperture 12 is bounded by a weakening profile 20. In the embodiment 15 depicted in Figure la), the can lid 10 or the zone 12 for the dispensing aperture is made from a light metal, e.g. aluminium. For mechanical reinforcement of the lid surface occupied by the zone 12, a circumferential bead 22 is provided therein. For reinforcement of the dispensing aperture a circumferential bead 25 is provided adjacent to the zone 12. The lever tab 14 in the embodiment depicted in Figure la) is in the so-called opener 20 position. That is, the first end portion or tab nose 16 is in a position partly overlapping with the zone 12 for the dispensing aperture. The lever tab 14 is connected to the lid surface 10 via a fastening means 24 in the form of a rivet. This connection is achieved via a retention tongue or strut 26, which extends from the fastening means 24 in the direction of the zone 12 for the dispensing aperture and transitions into the first end portion 16. 25 By lifting the second end portion 18 of the lever tab 14 in the opener position, the first end portion or tab nose 16 is pressed against the overlapping region of the zone 12 for the dispensing aperture. Due to the recesses 28 and 30 provided in the lid surface 10, the :\ sht\Interwovn\NRPortbl\DCC\SBT\5062930_I.DOC-10 04/2013 -17 second end portion 18 can be gripped and lifted particularly comfortably also with container lids having a very small diameter (see Figures 1b) and Ic)). In the embodiment of a container lid 2 of the invention depicted in Figure 1, where the second end portion 18 of the lever tab 14 is very close to the edge 6, a correct usage is practically forced on the 5 user due to the positioning of the recesses 28 and 30 in the lid surface 10 on both sides of the axis extending between the first and second end portions 16, 18 in the opener position (see broken line in Fig. la)). If the lever tab 14 is in a position turned from the opener position, a proper reaching under and gripping of the lever tab in the region of the second end portion 18 can usually no longer be achieved. In the represented embodiment the 10 handling of the lever tab 14 at the second end portion 18 is still further facilitated by the provision of gripping indentations 19 and 21, which, if the lever tab is in the opener position, correspond to the location of the recesses 28 and 30, i.e. the gripping indentation 19 lies above the recess 28 and the gripping indentation 21 lies above the recess 30. In this manner, problem-free lifting of the lever tab at the second end portion 18 is enabled 15 particularly with container lids having a small diameter or those container lids where the second end portion is very close to the edge 6. By lifting the lever tab, as shown in Figures 1b), the weakening profile 20 is first destroyed in only one place. If the lever tab 14 is pressed downwards further to the position shown in Figure 1 c), the weakening profile 20 is almost completely torn open or destroyed. The separated zone for the dispensing aperture 20 is pushed into the container interior by the interaction with the first end portion 16. By not designing the weakening profile to be entirely circumferential, but by providing instead a distance region (see also reference numeral 52 in Fig. 4) not having a weakening profile, this lid segment can be prevented from falling into the container interior (further details are given also with reference to Figure 5). 25 After the zone 12 for the dispensing aperture has been uncovered, the lever tab 14 may be pushed back to its original horizontal orientation, as shown in Figure Id). Subsequently, the lever tab 14 may be brought into the closure position by a 1800 rotation in the plane of the lid surface 10 (see Figure le)). The second end region 18 is then in a position over the dispensing aperture 12 (see Figure If)).
:\ sht\Interwovn\NRPortbl\DCC\SBT\5062930_I.DOC-10 04/2013 - 18 In the region of the second end portion 18 the lever tab 14 has a closure module 36, comprising a substantially circumferential closure collar 32 and an aperture closure 34. In the variant shown, the reversibly operable aperture closure 34 is inside the closure collar. On the side facing the upper side of the lid surface 10, the closure collar 32 is realised such 5 that the closure module 36 comprising the closure collar 32 and the aperture closure 34 may be pressed into the dispensing aperture in a sealing manner, as shown in Figure Ig). Figure 2 shows a representation of the container lid 2 of the invention. The closure module 36, comprising the closure collar 32 and the aperture closure 34, is accommodated in the dispensing aperture 12. The reversibly operable aperture closure 34 in the form of a flap lid 10 is connected to the lever tab 14 or the closure collar 32, respectively, via a hinge 38. Stop points 42, 44, 46 and 48 protruding from the lid surface 10 can further be seen from Figure 2. The stop points 42 and 44 prevent the lever tab 14 from rotating beyond an angle of 1800 and facilitate the correct adjustment of the closure module 36 in the closure position over the dispensing aperture 12. The stop points 46 and 48 are responsible for the lever tab 15 14 being able to be brought from the opener position to the closure position only in the direction of rotation (indicated by the arrow in Figure 2). Figures 3a) and b) show a container lid 2 of the invention, where the aperture closure 34 is in the opened position. As shown in Fig. 3b), the aperture closure 34 may be flipped backwards, i.e. in the direction of the recesses 28 and 30, even further beyond the position 20 shown in Figure 3a). Preferably the aperture closure 34 is reversibly held in this flipped open position by suitable locking or arresting facilities. In this way, a particularly interference-free drinking of liquid from the receptacle represented in Figure 3 is achieved. As indicated in Figure 3a), the aperture closure 34 may be used again for closing the container lid 2. To achieve a particularly tight fit, the circumferential edge 35 of the 25 aperture closure 34 can be brought into sealing engagement with the inner edge 37 of the closure collar 32. Those skilled in the art will be familiar with suitable locking connections or snap or clamp connections, respectively. From Figure 4, a schematic top view of a container lid 2 of the invention can be seen, without the lever tab, however. In the centre of the lid surface 10 there is the fastening :\ sht\Interwovn\NRPortbl\DCC\SBT\5062930_I.DOC-10 04/2013 - 19 means 24 for the lever tab (not shown). Circumferentially and adjacent to the weakening profile 20, the zone 12 for the dispensing aperture has an upwardly curved circumferential bead 22, which serves as a reinforcement of the area formed by the zone 12. Also adjacent to the weakening profile 20 there is a circumferential upwardly curved bead 50 adjacent to 5 the zone 12 in the lid surface 10. As can be seen from Figure 4, the weakening profile 20 is designed so as to be not entirely circumferential. Rather, there is a distance region 52 which is laterally offset from the axis A-A. On operation of the lever tab 14, the first end portion or tab nose 16, which, in the opener position, overlaps with a section of the zone 12 for the dispensing aperture, acts on the zone 12 adjacent to this distance region 52. By 10 pressing the first end portion 16 against the zone 12 by operating the lever tab 14, the weakening profile 20 ruptures such that on further operation of the lever tab the entire zone 12 is pushed into the container interior. The distance region 52 ensures that this zone does not become separated completely and cannot fall into the container interior. Rather, it is present in the container interior as an inwardly turned lid surface segment. 15 Figure 5 shows a schematic representation of a component of the lever tab 14, with the closure collar 32 as a part of the closure module 36. For the sake of clarity, the aperture closure 34 and the retention tongue are not shown. In Figure 5 the side of the lever tab 14 is seen which, when used in the generic manner, faces the upper side of the lid surface 10. The closure collar 32 on this side is provided with a circumferential seal 54. In the variant 20 illustrated the closure collar 32 extends into the first end portion 16 and also serves to stiffen the lever tab. At this end portion 16 the retention tongue or retention element (not shown) acts, which, together with the fastening means (not shown), provides the affixment to the lid surface. From Figure 6 a cross-sectional view of a container lid of the invention can be seen. The 25 closure collar 32 of the closure module 36 is inserted into the dispensing aperture 12 via locking teeth 56 as a part of the third arrestment 55. The circumferential seal 54 on the lower side of the closure collar 32 rests sealingly on the circumferential bead 50. The aperture closure 34 is inserted into the closure collar 32. Furthermore, the seamed edge 8 forming the edge of the lid surface 2 can be seen from Figure 6. Moreover, the affixment 30 of the lever tab 14 to the lid surface 10 via the fastening means 24 can be seen from Fig. 6.
: sbt\Interwoven\NRPortbl\DCC\SBT\5062930_l.DOC-l0 04/2013 -20 The fastening means 24, being a rivet in the embodiment shown in Fig. 6, retains the retention element 26 in a pivotably supported manner, the first end 27 of said retention element being overmoulded with the plastic material of the first end portion 16 of the lever tab 14. As Fig. 6 shows, in the embodiment illustrated the closure collar 32 is connected to 5 the retention element only in the region of the first end portion 16. Figure 7 shows an enlargement of detail A of Figure 6. The seal 54, which interacts with the bead 50, is equipped with two wedge-shaped, elastic ribs 58, 60, which act on opposite sides of the bead back. Moreover, the seal 54 has sealing walls 62, 64 adjacent to these sealing ribs and spaced at a distance therefrom, which are in contact with the upper side of 10 the lid surface 10. With the sealing construction 54 represented in Figure 7, a particularly effective liquid-tight insertion of the closure module 36 into the dispensing aperture 12 is achieved. The locking of the locking hooks 56 beneath the circumferential edge of the dispensing aperture 12 is configured such that, in the locked or arrested state, both the sealing ribs 58 and 60 and the sealing wall elements 62 and 64 are circumferentially 15 pressed against the upper side of the lid surface 10. This seal in a not-so-insignificant manner contributes to a reclosable container closure according to the present invention, which effectively prevents the escape of gases, such as carbon dioxide, from a container which has already been opened once before. From Fig. 8 an enlarged schematic sectional view of section B of Fig. 6 can be seen. 20 Adjacent to the edge 11 of the lid surface 10 bounding the dispensing zone or dispensing aperture 12, the circumferential bead 50 is present in the lid surface, extending axially away from the upper side of the lid surface 10. The closure module 36 is irreversibly connected to the lid surface 10 via locking teeth 56. In the closure position, the locking teeth 56 of the third arresting device 55 have been pressed into the dispensing aperture 12. 25 This is particularly well achieved in that bevelled surfaces 59 have been provided on the surface of the locking teeth 56 facing the lid edge. When pressing the closure module 36 into the dispensing aperture 12, these bevelled surfaces are pressed against the edge 11. It is advantageous if the locking teeth 56 or the third arresting device 55 are formed from a relatively rigid, but nevertheless still spring-elastic material. Suitable plastic materials 30 having these properties are known to those skilled in the art. The third arresting device 55 :\ sht\Interwovn\NRPortbl\DCC\SBT\5062930_I.DOC-I0 04/2013 -21 may have, for example, two, three, four, five or even more locking teeth 56 circumferentially along the edge 11 of the dispensing aperture 12. Particularly if only few locking teeth are used, for example two, three or four, it is advantageous to have them approximately equally spaced from each other and preferably not only engaging the lower 5 side of the lid surface 10 at points, but being of a wider-sized design. Alternatively it is also possible, as shown in Fig. 9, to realise the third arresting device 55 circumferentially, such that locking teeth 56 engage or grip the lower side of the lid surface 10 along the edge 11 along the entire circumference of the dispensing aperture 12. As soon as the edge 56 with the projection 61 has locked into the aperture edge 11 underneath the lid surface 10, 10 the closure module 36 is present in the dispensing aperture 12 in a sealingly locked state. The sealing enclosure of the closure module 36 via the circumferential seal 54, which interacts with the upper side of the lid surface 10, has already been described in detail with reference to Fig. 7. From Fig. 8 a reclosable aperture closure 34 can further be seen being inserted into the closure collar 32, said aperture closure being sealingly present at the inner 15 wall of the closure collar 32, for example via the circumferential bulges 63 and 65. Fig. 9 shows a schematic perspective top view of an embodiment of the third arresting device 55, which is realised circumferentially and which represents a part of the closure collar 32 (not shown). This third arresting device 55 in its circumference has a total of eight locking teeth 56. The locking teeth are provided with a rounded contact surface 59 20 and a locking projection 61 which reaches underneath and engages the lid surface 10 at the edge 11 of the same (not shown). In the variant shown, the respective locking teeth are realised having a relatively wide size and are separated only by narrow notches 67. The features of the invention disclosed in the preceding description, in the claims and in the drawings may, both individually and in any combination, be essential for the realisation 25 of the invention in its various embodiments.
