Description

Technical Field

[0001] The present invention relates to a lid of a can. In addition, the present invention relates to a method for manufacturing a can and a lid of a can.

Background Art

[0002] A beverage can having a cylindrical container made of aluminum or tinplate is known. The lid is folded thereon, and a metal tab is riveted thereto as an opener. When the metal tab is lifted, an oval score line is broken, and a part of the lid is pushed into the can to uncover the drinking opening. A disadvantage is that it is not possible to reseal the beverage can. As a result, the beverage inside the can can quickly become stale. In addition, during further transportation, the beverage can easily spill.

[0003] Re-sealable lids for cans are also known. For example, EP 2 614 010 B1 describes a lid for a container in which a closing element arranged on the lower side can be pivoted between a closed position and an open position by an actuating element arranged on the upper side. However, the closing element and the actuating element are large components that are disadvantageous during filling. In addition, in this way, the lid of the can is heavy and expensive. Furthermore, the actuating element and the closing element are usually made of plastic, which makes recycling difficult. Moreover, the rotational movement requires a high actuating force that, for example, subjects the components to unfavorable stresses by strong shear forces.

[0004] The object of the present invention is to improve the lid of a can that is re-sealable. Furthermore, the object of the present invention is to improve a method for manufacturing a re-sealable lid of a can and a re-sealable can.

[0005] These objects are achieved by the subject matter of the independent patent claims. Advantageous configurations with useful modifications of the present invention are shown in the individual dependent claims.

Summary of the Invention

Means for Solving the Problems

[0006] The first aspect relates to a can lid for a can. The can may preferably be configured as a beverage can and / or a storage container for bulk material. The can lid may preferably comprise at least one lid panel configured to demarcate the top of the can by pressing the outer circumferential edge of the lid panel against the outer wall of the can. In terms of material and design, the lid panel may, for example, correspond to the lid of a conventional beverage can. For example, the lid panel may be made of aluminum or tinplate, optionally with a plastic coating, for example, as corrosion protection. The lid panel may have at least one pouring opening through which a substance present in the can can be poured out. Preferably, the pouring opening is always provided within the lid panel. The pouring opening is therefore not broken open by a metal tab when the can is first opened, as is the case with beverage cans.

[0007] The can lid may have an actuation element positioned on the upper side of the lid panel, facing outward from the inside of the can when the can lid is attached to it. In addition, the can lid may have a closing element positioned on the lower side of the lid panel, facing inward from the inside of the can when the can lid is attached to it. The closing element may be shiftable between a closed position, where the closing element closes the dispensing opening in a liquid-tight and / or airtight manner, and an open position, where the dispensing opening is at least partially uncovered, by substantially translating along the lid panel in an induced manner using the actuation element. The translation is very intuitive, places little stress on the connection between the closing element and the actuation element, and requires a low actuation force.

[0008] Preferably, the closing element and / or operating element are made from a metallic material, preferably aluminum or tinplate. This promotes recycling. Preferably, the closing element and / or operating element are made from the same material as the lid panel and / or can body, so that the entire can is recyclable without assembly. For example, the closing element and / or operating element are made from tinplate or aluminum sheet and may optionally have a plastic layer for corrosion protection. Preferably, the plastic layer is provided both inside and outside of the lid panel, closing element, operating element, and / or can body.

[0009] On its upper and / or lower sides, the closure element is preferably not planar. In particular, the closure element may have one or more recesses or one or more protruding sections on its upper side. Such recesses may be formed, for example, within the area of ​​the rivet ripple or as lower recessed sections corresponding to the rivet ripple. Protruding sections corresponding to air channels extending along the upper side of the closure element may be formed, for example, on its lower side.

[0010] The closing element and the operating element are fastened together by a connection. The connection is preferably of fixed and / or non-variable length. In other words, the distance between the operating element and the closing element within the area of ​​the connection is preferably fixed and / or non-variable. This allows for the automatic adjustment of a constant pressure on the closing element against the lid, among other things, which will be discussed in more detail below.

[0011] Preferably, the closing element and the operating element are fastened to each other using connections that do not penetrate the closing element. In this way, the contents of the can are reliably protected. In particular, unwanted leakage with a closed lid can be eliminated. Such connections are advantageous when metal materials are used for the closing element and / or operating element, as the through-opening for the connection can only be sealed with considerable effort and tends to leak under pressure. Riveted connections are particularly preferred. Riveted connections can withstand large forces particularly well, for example, in the case of heavy operation. In addition, riveting techniques enable high production rates with low rejection. Welded connections are also particularly preferred because only small amounts of material are required. For example, the operating element and the closing element may be fastened together using ultrasonic or friction welding, in particular when plastic is used to manufacture the closing element and / or operating element.

[0012] As the closing element is shifted from the closed position to the open position, the connection may move along the guide slot in the lid panel. The connection, in particular rivets, rivet sections, and / or welded sections, may therefore be positioned within the plane defined by the lid panel. In particular, the connection may be positioned through the lid panel, i.e., within a through-opening in the lid panel. Thus, the connection may also serve as a guide. In addition, the overall height of the can lid may therefore be particularly flat, which is advantageous for filling. For example, the overall height determines the number of lids that can be provided in a magazine. Thin, resealable can lids, as well as those of non-resealable can lids, allow for magazine filling. Therefore, compared to non-resealable cans, the production rate on the same filling line is the same, or only slightly lower.

[0013] The lid panel preferably has an outer diameter of at least 4.5 cm, at least 5 cm, or at least 5.5 cm. The outer dimensions of the lid panel away from the through-opening may correspond to standardized lid panels for beverage cans, particularly B64 or CDL lid panels. B64 lid panels may be, for example, types 200, 202, 204, 206, or 209. CDL lid panels may be, for example, types 200 or 202. The lid panel may be substantially flat and / or round in shape, preferably circular. The lid panel may have circumferential beads that increase its stability and help form a folded edge. The lid panel may also be referred to as the shell.

[0014] The flat side of the can lid facing the storage space, preferably the flat side facing outward from there, is preferably coated with plastic or covered with a plastic film. This serves to protect against corrosion and protect the substance stored in the can. For example, it is possible to prevent the metal from being decomposed by the liquid contained in the can. For example, it is also possible to prevent metal particles from entering the beverage. In addition to this coating or film, the lid panel, operating elements, and / or closing elements may be made from a metal material, in particular from one metal material and / or identical metal materials. The closing elements may be substantially flat and / or rounded in shape.

[0015] The cans for which the lids are provided are preferably for storing beverages, soups, or bulk products. Beverages may contain fibers, such as pulp in the case of orange juice. Bulk materials may be, for example, spices. Soups may contain fragments, such as noodles or pieces of meat. Preferably, the pouring opening is large enough to allow them to be poured out. For this purpose, the closing element in the open position may expose a pouring opening larger than the solids inside the can. The pouring opening may be a through opening from the inside to the outside of the can. The cross-section of the pouring opening is preferably at least 1.5 cm. 2, more preferably, at least 1.8 cm 2 Most preferably, at least 2 cm 2 That is the case.

[0016] The dispensing opening is preferably oval, circular, or crescent-shaped. In the longitudinal direction of the guide slot, the front and rear edge sections of the dispensing opening are preferably arc-shaped and / or curved. Preferably, both the front and rear edge sections are curved in the same direction. As a result, at the edge section of the dispensing opening where the guide slot is located, the lid panel preferably forms two protrusions projecting into the dispensing opening. The connection can be guided through these protrusions at the foremost position of the closing element.

[0017] The guide slot may be a through-opening within the lid panel. Preferably, the guide slot is formed as an extension opening. The width of the guide slot may be substantially constant over its length. The guide slot may determine the parallel movement of the closing element and the operating element between the closed position and the open position. At least a portion of the closing element and / or the operating element may be guided through the guide slot, for example, by the portion that abuts against the edge of the lid panel that demarcates the guide slot. Preferably, the individual outer walls of the guide slot, which form the radial inner edge of the lid panel and / or are the edge of the lid panel, may thus form the guide.

[0018] The dispensing opening and / or guide slots are preferably perforated. They may also be perforated passage divisions within the lid panel. The closing element may seal the interior opposite the dispensing opening in the closed position, for example, by using a seal and / or by pressing it against the lid panel. This pressing may be carried out by preloading and / or by connecting to an actuating element. The actuating element may move with the closing element, i.e., it may also preferably be guided along the lid panel in a substantially parallel movement manner. Using their connections, for example by rivet connections, the actuating element and the closing element are permanently connected to each other during normal use. When used as intended, such as opening and closing the can, preferably the actuating element and the closing element are not intended to be separated from each other. The connections may be configured to fix the actuating element and the closing element to the lid panel. Preferably, the connections, in particular rivet connections, are preloaded. The actuating element may be cambered by preloading. The camber is preferably formed in a direction that is reduced by increased internal pressure and / or by pressing it against the actuating element. This facilitates opening.

[0019] In the closed position, the closing element preferably covers the dispensing opening and guide slot in an airtight and / or liquidtight manner. The closing element preferably extends further across the lid panel than the dispensing opening and guide slot. The closing element is preferably rotationally symmetric, which allows for easier processing during the manufacture of the closure. In the closed position, the individual outer edges of the closing element are preferably positioned radially outward of the individual through-openings in the lid panel. The diameter and / or length of the closing element, in particular the diameter and / or width of the area surrounded by the seal of the closing element, is preferably greater than the length between the front point of the dispensing opening, in particular the length between the apex of the dispensing opening and the opposite rear end of the guide slot.

[0020] The operating elements preferably extend further across the lid panel than the dispensing opening and guide slot, especially in the closed position. In the closed position, the operating elements preferably cover the dispensing opening and guide slot. This can prevent dust accumulation on the operating elements within the guide slot and / or dispensing opening. When the can lid is viewed vertically along an axis perpendicular to the lid panel, i.e., when the beverage can is upright, the operating elements are preferably configured to completely overlap the dispensing opening and / or guide slot in the closed position. In the open position, the operating elements uncover at least 50%, preferably at least 70%, and more preferably at least 90% of the area of ​​the outlet opening. The contents of the can are therefore directly accessible through the uncovered area, for example, via a straw. That is, a straight straw, without bending or twisting, may pass through the outlet opening in the entire unoverlapping area along the viewing axis (vertically to the can). This corresponds to a style known to consumers from common beverage cans. In addition, this can facilitate the dispensing of liquids containing fibers or fragments.

[0021] The upper side of the can lid and / or individual parts may also be referred to as the outer side. Similarly, the lower side may also be referred to as the inner side. Preferably, only a single connection, such as a riveted connection or a single weld point, is provided between the actuating element and the closing element. This makes the production of can lids particularly fast and inexpensive.

[0022] Preferably, the connection is provided by a nipple formed on a closing or operating element that connects to a corresponding other element. For example, the nipple may be riveted or welded. The nipple, formed as a rivet ripple, may be positioned within a corresponding rivet opening of the other of the two elements. Preferably, the nipple is embossed. For example, the metal sheet on which the element having the nipple is formed may be embossed to form the nipple. Preferably, the nipple is formed integrally with the element. The nipple may be formed as a protruding section. The rivet ripple can eliminate the need for separate components such as rivets, as well as the need to puncture the closing element to form the connection. The nipple also allows a defined welding area to be specified in the case of welding. A similar rivet connection holds a metal tab, which is riveted to the lid panel as a built-in can opener on conventional beverage cans. For riveting, and therefore preferably, it is also possible to use a plant for the production of conventional cans, making the conversion to the production of resealable can lids particularly cost-effective. Preferably, the rivet ripple is formed in the closing element and protrudes upward. The rivet opening may be a through opening, preferably formed in the operating element. The connection may therefore be configured not to penetrate the closing element.

[0023] Preferably, the rivet opening extends through a projection, particularly through a projection of the actuation element that protrudes in the direction toward the underside of the lid panel. The projection allows for a smaller overall thickness of the can lid. For this purpose, the projection may preferably extend into a guide slot. Preferably, the projection may be formed by embossing. To that extent, the projection may be formed by a recess in the actuation element relative to a surrounding flat area. Preferably, the adjacent area is the fastening section of the actuation element, which will be described later. Preferably, the rivet opening is located within the fastening section, particularly in the center. The projection may protrude in the direction of the element with the rivet ripple. Preferably, the projection protrudes from the underside of the actuation element. For example, the projection may protrude from an imaginary plane in which the fastening section is located.

[0024] Preferably, in the open and / or closed positions, the projection extends at least partially through the guide slot. The projection may also thus serve as part of the guide. In addition, this preferably provides a means for fixing the actuating element against rotation. In the closed position, the projection may also extend at least partially through the dispensing opening.

[0025] Preferably, the connection is formed narrower than the guide slot, particularly in the area extending at least through the guide slot, in the form of a rivet connection. In particular, the protrusion may be formed narrower than the guide slot in the area extending at least through the guide slot. Preferably, the connection is wider than the guide slot in the area extending above and / or below at least the guide slot. This enables the connection, particularly the rivet connection, to be supported on the lid panel. Thus, for example, loads due to internal pressure may be supported. The width is preferably measured in the plane of the lid panel. This plane may correspond, for example, to the plane in which the guide slot is formed. The width is preferably measured transversely to the longitudinal axis extending between the front opening of the guide slot and the rear end of the guide slot, particularly perpendicular to this longitudinal axis. The width may also be perpendicular to the vertical direction. The thickness may be measured in the vertical direction. The vertical direction is preferably perpendicular to the plane in which the lid panel extends.

[0026] Preferably, at least one planar surface is formed on the connection within the area extending through the guide slot, and the at least one planar surface preferably faces the edge of the lid panel, the edge delimiting the guide slot. This planar surface enables the connection to be supported on the guide slot and thus function particularly well as anti-twist protection. Preferably, at least two planar surfaces are formed on the connection within the area extending through the guide slot. Preferably, the two planar surfaces are formed on opposite sides and / or substantially parallel. Preferably, at least one planar surface is formed on the protrusion. Preferably, at least two planar surfaces are formed on the protrusion. The individual planar surfaces may bear against the edge of the lid panel defining the guide slot and provide anti-twist protection. The rivet opening and / or the remaining protrusion are preferably round in shape, particularly circular. Within the area of the planar surface, the round shape may be flattened. Similarly, the nipple, particularly the rivet ripple, may be round in shape, particularly circular.

[0027] Individual planar surfaces preferably extend in a direction perpendicular to the plane of the lid panel, i.e., in a vertical or upward direction, and / or parallel to the longitudinal axis of the guide slot and / or parallel to the edge of the lid panel delimiting the guide slot. Instead of planar surfaces, curved, stepped or toothed surfaces may also be provided, which provide at least two defined contact points with the edge of the lid panel delimiting the guide slot. Even in this way, anti-rotation protection may be provided.

[0028] Optionally, further protrusions may be provided on the closing and / or actuating elements for guidance.

[0029] Preferably, the lid of the can has at least one seal arranged between the closing element and the lid panel, at least in the closed position of the closing element. The seal is preferably made of a material softer than the closing element. In particular, silicone, rubber, elastomer, thermoplastic or elastomeric thermoplastic may be used. In this way, a safe and pressure-resistant reseal can be reliably achieved. Preferably, only a single seal is provided that seals the closing element against the lid panel at the contact points. Preferably, the closing element has a support section within the area of connection with the actuating element. Preferably, the closing element rests only along its outer edge against the lid panel via the seal. The support section is preferably provided in the center and preferably also rests against the lid panel. A recessed channel may be provided between the seal and the edge.

[0030] The seal preferably forms a closed circumference, for example, in the form of an O-ring. The cross-section of the seal may differ from a round cross-section. The seal may be formed from a flexible material such as rubber, raw rubber or plastic. The seal may be arranged circumferentially on the edge of the closing element.

[0031] Preferably, the seal is at least partially received in a groove formed on the upper side of the closing element. The groove allows the seal to be held securely, in particular, during repeated opening and closing. The groove may be radially and circumferentially arranged on the outside of the closing element. The groove may be arranged inside the closing element along the outer edge of the closing element. Preferably, the groove is open in the direction of the lid panel. The groove may be formed, for example, by an embossing or deep drawing process. The groove may also be formed as a deformation in the plane of the sheet, for example, as a bead. In this case, for example, the material thickness of the closing element within the area of ​​the groove may be uniform. The groove may also be provided by press-fitting or removing material from the closing element, for example, by local thickness reduction.

[0032] The seal is preferably secured to the closing element using its outer edge, which is bent into and / or across a section of the seal. This allows the seal to be held particularly securely on the closing element, which can be advantageous during assembly. In addition, the seal may also cover the open cut edge, for example, in the case of a closing element perforated from a metal sheet. For example, this cut edge may be formed without a plastic coating and therefore protected by the seal against corrosion and / or contact with the liquid inside the can. Advantageously, the groove may be crimped with the outer edge during the folding process. Thus, even sharp edges may be covered. Preferably, the seal may be positioned within the groove and crimped by the outer edge. The outer edge may be radially outward and circumferential. The outer edge may be a perforated or cut edge. The outer edge may be press-fitted into the seal. Due to its curvature, the outer edge may be radially positioned further inward than the adjacent area of ​​the closing element.

[0033] The seal may be fixed in the groove, for example, by adhesive, in addition to or as an alternative to tightening with the outer edge. The seal may also be injected into the groove.

[0034] The seal may have an undercut. The undercut may be located at least partially within the groove or outside the groove. Alternatively, or in addition, the cross-section of a portion of the seal received within the groove may be smaller than the cross-section of the groove. Alternatively, the seal may optionally have a margin extending from radially outward to radially inward with a recess below the margin. The undercut and / or margin may be formed circumferentially. The cross-section of the seal may be appropriately configured to have a smaller cross-section than the margin, undercut, and / or groove. These individual configurations allow the closing element to be displaced with a lower operating force. In addition, the sealing effect is increased. Furthermore, the seal may seal substantially equally well at different contact pressures. For example, in a beverage can, the internal pressure may fluctuate depending on the temperature, and in the case of carbonated beverages, due to movement. The seal configuration allows for reliable sealing over a wide range of internal pressures.

[0035] The seal may have a round, square, or irregular cross-section.

[0036] Optionally, the seal may have two seal edges that are spaced apart from each other and rest against the closing element or lid panel in at least the closed position. Preferably, the two seal edges lean against the underside of the lid panel, and the seal is positioned within a groove on the closing element. Double seal edges allow for a secure seal even at low internal pressures, for example, in non-carbonated beverages. Two separate seals, each with at least one edge, may also be provided.

[0037] Preferably, the lid panel and / or closing element has a notch or embossing in part that is positioned adjacent to or demarcates a portion of the dispensing opening, which is first uncovered when the closing element is repositioned from the closed position to the open position. As a result, a hissing sound may be produced when the pressurized can is opened. This can signal the freshness of the contents to the consumer. In addition, the sound may thus be similar to that of a can that cannot be resealed when opened, providing consumers with further similarity to the opening and closing effect of conventional cans. At the start of the opening process, the notch or embossing may form a small channel and / or nozzle. For example, the embossing or notch may be tapered. The hissing sound may be produced, for example, by accelerating the outflow gas to supersonic speeds.

[0038] The notch or emboss is preferably located within the area of ​​the front end of the dispensing opening, which may correspond to the apex of the dispensing opening. In the closed position, the closing element may overlap with the notch or emboss. In the open position, the closing element may not overlap with the notch or emboss.

[0039] Preferably, the lid panel further includes a pressure equalization opening. The pressure equalization opening may also generate a hissing sound at the start of the opening process. In addition, the actuation force required to reposition the closing element from the closed position to the open position can be reduced. Preferably, the pressure equalization opening is closed in a liquid-tight and / or airtight manner by the closing element in the closed position, and at least partially uncovered in the open position. The pressure equalization opening may be positioned so as to be uncovered in front of the dispensing opening when the closing element is repositioned from the closed position to the open position. The pressure equalization opening may be configured as a separate opening not connected to the dispensing opening and / or guide slot. For example, this may be a through-opening in the lid panel positioned in front of the dispensing opening in the direction of displacement to the open position. The pressure equalization opening is preferably located, in particular, at the apex of the dispensing opening, within the area of ​​the front end of the dispensing opening. In the closed position, the closing element may overlap the pressure equalization opening. In the open position, the closing element may not overlap with the pressure equalization opening.

[0040] The cross-section of the pressure equalization opening is preferably smaller than the cross-section of the dispensing opening. For example, the cross-section of the pressure equalization opening is a maximum of 20 mm. 2 Preferably, up to 10 mm 2 , or more preferably, up to 5 mm 2 This may also be the case. Preferably, the pressure equalization opening is smaller than the normal cross-section of a straw, which may also be called a drinking straw.

[0041] In the open position, an air channel is preferably formed between the closure element and the lid panel, with the first end of the air channel preferably open on the upper side of the lid panel and / or in an end region facing outward from the outer edge of the lid panel at the dispensing opening, and the second end of the air channel preferably open on the lower side of the lid panel in the end region of the closure element, with the end region facing outward from the dispensing opening. The second end may connect the inside of the can to the outside and / or the dispensing opening. This facilitates and / or pre-sets the strength of backflow of air, which can facilitate dispensing. For example, the air channel can prevent irregular and / or forceful dispensing of the liquid, thus enabling more uniform dispensing.

[0042] Preferably, the air channel is blocked in the closed position and / or at an intermediate position of the closing element between the open and closed positions. For example, the air channel may be blocked by closing one or both ends. For example, the intermediate position may be a position where the dispensing opening is not covered as much as possible, for example, only 80%, 70%, or preferably 50% at most. In particular, the blockage may be provided by a sealing element that abuts the underside of the lid along the entire circumference of the closing element. For example, in the closed position and / or intermediate position, the closing element may not have to be lifted from the lid panel in some sections, otherwise the air channel would not be blocked (especially at the second end).

[0043] Preferably, at least a portion of the air channel is formed by recesses in the closure element and / or lid panel. The recesses may be formed, for example, by embossing. Due to the recesses in the lid panel, the closure element can have a particularly simple configuration. The recesses in the closure element can make the lid panel particularly robust and inexpensive.

[0044] Preferably, in the open position, the first end of the air channel is formed by a gap between the closing element and the operating element, and / or between the seal and the operating element. In the closed position, a portion of the lid panel is preferably positioned within the gap, thereby blocking the airflow. The gap may be closed simply by shifting the operating element, and therefore the closing element, to the closed position. Such a structure is kinematically simple and reliable.

[0045] Preferably, the second end of the air channel in the open position is formed by the gap between the closing element and the lid panel, and / or between the seal and the lid panel.

[0046] According to the first modification, the gap is formed, in particular, in the open position, by the deflection of the closing element at the projection of the lid panel facing the closing element or bead. With respect to the deflection, the lid panel, the actuation element, and / or closing element may be elastically deformable. This can eliminate the need for separate joints to form an air channel. In particular, the closing element may be deflected downward in the open position at the radially outer bead of the lid panel, thereby canceling the sealing effect of the closing element with the underside of the lid panel in the deflected section. The closing element may be tilted downward. Rotational downward deflection, which may also be called tilting, is produced, for example, by deformation, in particular elastic deformation. The closing element and / or seal are deflected downward, for example, along the end region facing outward from the pouring opening. The end region of the closing element and / or the bead on the lid panel may act like a slope to lift the closing element away from the lid panel section by section. At least some segments of the edge of the closing element may be chamfered to lift it, particularly within the area facing outward from the dispensing opening. Alternatively, or in addition, the lid panel may have one or more downward-projecting embossings that deflect at least some segments of the closing element downward in the open position, thereby canceling the sealing effect of the closing element with the underside of the lid panel in the deflected segments.

[0047] According to the second modification, the second end of the air channel is formed in the open position by a lid panel having one or more embossings projecting upward, the embossings forming a passage for air around the closing element (particularly around the seal) in the open position of the closing element, thereby canceling the sealing effect of the closing element with the underside of the lid panel within the area of ​​the one or more embossings. In this modification, the closing element may also not have a joint for pivoting the closing element relative to the lid panel.

[0048] When the can lid is viewed along an axis perpendicular to the lid panel, i.e., vertically in the case of a conventional beverage can, the closing element is preferably positioned such that, in the open position, it has one or more protrusions or embossings projecting upward and / or downward, or preferably overlaps with the bead of the lid panel within the trailing edge section. In the closed position, the closing element does not overlap with any protrusions, embossings, or beadings. The trailing edge region may be defined as the edge region facing outward from the pouring opening and / or furthest from the pouring opening.

[0049] Preferably, the guide slot and the dispensing opening form a common through-opening in the lid panel. The dispensing opening and the guide slot are preferably connected to each other. Preferably, the guide slot has a front opening from which the guide slot opens to the dispensing opening and which extends preferably linearly to the rear end. By forming them together, the guide slot and the dispensing opening may be manufactured together inexpensively, for example, by a single perforation.

[0050] Preferably, the guide slot is elongated, and the longitudinal direction of the guide slot corresponds to the displacement direction of the closing element. The longitudinal direction of the guide slot may correspond to the repositioning movement of the operating element during opening and closing. The guide slot is preferably linear and / or at least partially centered within the lid panel. The guide slot is preferably at least 0.7 cm, more preferably at least 1 cm, and particularly preferably at least 2.5 cm in length. For example, the guide slot may be 2.5 cm in length. In this way, a large dispensing opening may not need to be covered. The guide is preferably at least 2 mm, more preferably at least 3 mm, and particularly preferably at least 4 mm in width. For example, the guide slot may be 3 mm wide. In this way, the connection between the closing element and the operating element may be formed with sufficient stability. The guide slot may be, for example, rectangular.

[0051] The actuating element is preferably supported within an outer section on the lid panel and thus acts as a disc spring, pressing the central region of the actuating element, provided around the connection, away from the lid panel. Preferably, the closing element is pressed against the underside of the lid panel by the connection. The central region may be recessed with respect to the outer section. The actuating element may be supported on the upper side of the lid panel via the outer section, thereby pressing the upper side of the closing element and / or the upper side of the seal against the underside of the lid panel. This support may be reinforced by a camber, and / or the central region may act as a camber. The camber may correspond to a concave surface. The section of the connection itself is preferably not counted as part of the central region. In particular, the protrusion with a rivet opening is preferably not counted as part of the central region. The central region preferably does not lean against the lid panel. The actuating element is therefore preferably curved upward away from the lid panel within the central region, thereby the outer section may be pressed against the lid panel due to the connection with the closing element. In this way, it is possible to pre-set substantially equal operating forces even under different internal pressures.

[0052] Preferably, the guide slot has at least one relief notch at its end facing outward from the dispensing opening. The avoided end may be the rear end of the guide slot. The relief notch may otherwise form a radius at the corner of the rectangular cross-section. For example, the relief notch may be perforated such that its end does not have a right angle. This can prevent the lid panel from tearing or cracking under high internal pressure. The individual relief notches preferably extend substantially perpendicular to the longitudinal direction of the closing element. The individual relief notches are preferably curved, and the center of the circle of curvature is preferably closer to the center of the lid panel than the relief notch. The individual relief notches may, for example, be arched in shape. The length of the relief notch, in particular the arc length, may exceed the width of the guide slot.

[0053] Preferably, the actuating element has at least one fastening section into which a connection to a closing element is formed, particularly a rivet connection or a closing element, and a handle section connected thereto, configured for gripping for the purpose of repositioning between an open position and a closed position. The sections of the actuating element may be integrally formed and / or substantially flat. In particular, the actuating element may be formed from a single sheet metal element that has been deformed, particularly bent, to form the section. The fastening section is preferably flat and / or has a thickness of less than 3 mm, preferably less than 2 mm, in the direction perpendicular to the lid panel. The upper side of the fastening section is preferably formed substantially flat, optionally away from a recess for a rivet connection. The fastening section and / or handle section preferably extend substantially parallel to the upper side of the lid panel, particularly to the central region, at least prior to the initial opening. The fastening section preferably extends substantially parallel to the upper side of the lid panel even after the initial opening, particularly during displacement along the guide slot. The handle section is preferably formed in the end region of the actuarial element facing outward from the dispensing opening, which makes its operation particularly ergonomic. In addition, the handle section is therefore particularly well protected from contamination by the contents of the can.

[0054] Preferably, the handle section may be pivotable, preferably manually pivotable (i.e., directly by hand), between a retracted position in which the handle section is positioned substantially parallel to the lid panel and / or fastening section, and an operating position in which the handle section is grippable for repositioning between the open and closed positions. The stack height of the can lid during filling is therefore particularly low, but the handle section is nevertheless easy to grip during operation. The handle section is preferably flat and, in the retracted position, has a thickness of less than 3 mm, preferably less than 2 mm, in the direction perpendicular to the lid panel. The upper side of the handle section is preferably substantially flat. In the retracted position, the upper side of the fastening section and the upper side of the handle section form substantially one plane. When the handle section is in the retracted position, the operating element may be substantially planar. When repositioned from the retracted position to the operating position, the handle section is preferably pivoted upward. In particular, the rear end region of the handle section, which is furthest from the dispensing opening, is pivoted upward. Preferably, in the retracted position, at least the lower portion of the handle section is separated from the upper portion of the lid panel. Thus, the handle section may be easily lifted manually, in particular with fingers, for example, with fingernails. Preferably, in the operating position, the lower portion of the handle section is separated from the upper portion of the lid panel, at least within the section, preferably completely. Thus, it is possible to grip the handle section at least partially, for example, with two fingers, so that force can be applied in a direction parallel to the upper portion of the lid panel, in particular manually. The pivot of the handle section may be an upward fold, preferably an upward fold at an angle of at least 30°, preferably at least 45°, and particularly preferably at least 60°. Preferably, the handle section is pivoted upward from the closed position to the open position with respect to the direction of movement of the operating element and / or closing element. The central region may be formed by the handle section and / or the fastening section.

[0055] Preferably, the fastening section and the handle section are connected by a hinge, particularly a film hinge, the hinge axis of which extends preferably perpendicularly to the longitudinal and transverse directions of the guide slot. The film hinge preferably extends along the entire width of the actuating element, particularly the entire width of the fastening section and / or handle section, preferably along an imaginary straight line, in the longitudinal and transverse directions of the guide slot. Optionally, the film hinge may be continuous or formed from several separate sections.

[0056] The film hinge is preferably configured such that the mold does not break when the handle section is pivoted, in particular, does not break during the first pivot, and preferably does not break during repeated pivots (at least 5 times, at least 10 times, at least 20 times, or more).

[0057] The handle section may be configured to pivot about a hinge axis relative to the fastening section for repositioning between a stowed position and an operating position. The hinge facilitates the operation of the operating element, particularly the pivoting of the handle section. The film hinge may be formed by a section within the operating element having a thinner overall thickness, particularly in the form of a notch which can be produced, for example, by embossing or scratching. The thinner section, particularly in the form of a notch, preferably extends from its upper side into the operating element, particularly downward. The film hinge may further have the advantage that it deforms, allowing the handle section to remain in the operating position even against gravity.

[0058] Preferably, the handle section has a starting position, preferably corresponding to the stowed position. The actuating element may be configured such that, after being initially repositioned from the starting position, the handle section can no longer be permanently repositioned to return to the starting position. Alternatively, or in addition, the actuating element may be configured to be plastically deformed when the handle section is initially repositioned from the starting position, in particular so as to be permanently and / or permanently visually recognizable. For example, the handle section may remain in the actuating position. The handle section may be automatically repositioned to return only to a partially reset position, in particular so as to be visually different from the starting position. In particular, any deformation returning to the starting position cannot occur as a result of intended use. The deformation may be configured such that it cannot be reversed by the user without being visually recognizable. This can provide an original feature that allows the user to recognize whether the can or can lid has already been opened. This is particularly advantageous for hygienic reasons.

[0059] Preferably, the outer edge of the actuation element is rounded, and preferably folded. This allows for the avoidance of sharp edges that might otherwise be uncomfortable for the user during operation. Preferably, the outer edge of the fastening section and / or handle section is rounded, and in particular, folded. In particular, the outer edge may be curved inward toward the underside of the actuation element, preferably.

[0060] Preferably, the actuating element has a locking segment, which is used to lock the actuating element onto the lid panel in the closed position prior to its initial repositioning from the closed position to the open position. This prevents unintentional opening. The locking segment may also function as a transport lock. In particular, the locking device may be formed by a snap connection of the locking segment to the form-closed and / or lid panel. The locking segment is preferably located between the end of a handle segment spaced apart from the dispensing opening and a fastening segment.

[0061] Preferably, the locking section has a locking element that protrudes downward from the underside of the actuating element. In this way, the lock can be protected against operation. Preferably, the locking section is formed integrally with the actuating element, and therefore the locking section is also formed integrally with the actuating element. Preferably, the locking section is configured such that when the actuating element is pushed open without lifting the handle section, the handle section is pushed out, preferably with irreversible deformation, in particular upward from its starting position. This provides additional protection against undetectable initial opening.

[0062] Preferably, the locking element is configured as a hook. The hook is preferably L-shaped. The hook may be formed integrally with the remaining locking section.

[0063] Preferably, prior to the initial repositioning from the closed position to the open position, the locking element is positioned within the guide slot, preferably in the end region of the guide slot facing outward from the dispensing opening, where it engages with the lid panel. The width of the hook is preferably smaller than the width of the guide slot at the engagement point. For example, the thickness of the hook, measured in the longitudinal direction of the guide slot, is preferably less than the width of the hook. The hook is a very simple locking element, which can be manufactured particularly easily, especially if the actuation element is formed from a metal plate.

[0064] Preferably, the locking element is positioned within a recess of the closing element prior to the initial repositioning from the closed position to the open position. As a result, the can lid may have a particularly low overall height, even with the locking element. The recess may be produced, for example, by deep drawing or embossing. The recess may also be a groove, in particular a rotationally symmetric groove. The recess may also be part of an air channel, as already described, from which additional recesses can be dispensed.

[0065] Preferably, the locking section prevents the movement of the actuarial element from a closed position to an open position via a morphological fit. In particular, repositioning of the handle section from the stowed position may preferably result in the release of the lock, in particular permanent release, by deforming the locking element of the locking section. For example, the deformation may be plastic, and therefore preferably permanent. The locking section is preferably configured to move together with the handle section. For this purpose, the locking section may be formed on the handle section and / or on the locking section, the handle sections may be mounted to each other, and / or the locking section may be connected only to the fastening section via the handle section. The handle section and the locking section may be common sections of the actuarial element, at least in part.

[0066] The locking section is preferably connected to the fastening section by a hinge, particularly via a film hinge. This hinge, in particular the film hinge, is preferably the same film hinge to which the handle section is also connected to the actuation element.

[0067] Preferably, the locking section is located below the handle section. This allows the total area occupied by the actuation element on the upper side of the lid panel to be particularly small. Preferably, the locking section does not extend beyond the edge of the handle section.

[0068] Preferably, the locking section and the handle section are formed from two different layers of material. For example, the locking section may be a section of sheet, particularly folded on the underside of the handle section.

[0069] The two layers of material are preferably formed integrally with a portion of the edge of the handle section, forming a transition between the locking section and the handle section. Preferably, this transition has a smaller overall thickness compared to the rest of the handle section to facilitate reaching down to pivot the handle section from its stowed position.

[0070] Preferably, the locking section is secured to the handle section by the folding edge of the handle section. In this way, a sharp outer edge can be prevented while the locking section is being tightened to the handle section. For example, the edge of the handle section may preferably fold inward toward the underside of the handle section.

[0071] The locking segment may be configured to re-lock on the lid panel after the closing device has been re-closed. This can further prevent unintentional opening. For example, the locking element may re-engage on the lid panel when the actuation element is repositioned to the closed position and / or the handle segment is repositioned to the retracted position.

[0072] Preferably, the operating elements are formed integrally. In particular, the locking section, handle section, and fastening section with locking elements may be formed integrally from a metal plate or manufactured integrally by injection molding.

[0073] Preferably, the closing element has at least one support section. The support section may abut the underside of the lid panel in an area corresponding to the hinge position at least between the handle section and the operating section. Thus, there may be overlap of the support section with the hinge in the vertical direction. The support area may be an area without embossing and / or recessing, for example, particularly with respect to the air channel. The support area may abut the lid panel. The support area can prevent unwanted deformation and / or overloading of the lid panel when the handle section is folded upward. In addition, upward folding may be facilitated. The support area is preferably provided within the end region of the hinge at least in the direction of the hinge axis, as the lid panel is particularly subjected to load therein. Thus, the support area may also support the hinge and the lid panel. Preferably, two support sections are provided, one for each end region. Preferably, the air channel extends between these support sections. Alternatively, the air channel may also extend outside the support section, for example.

[Modes for carrying out the invention]

[0088] Figure 1 is a schematic perspective view, from above, showing a resealable can lid 10 for a can, for example, a beverage can. The can lid has a lid panel 12 that closes the top of the can body when attached to the can body. The upward direction of the can lid 10 may be defined by the standing can. The upper side of each individual part of the can lid is defined with respect to the side facing outward from the inside of the can. The lower side of each individual part faces inward. The terms “top” and “bottom” or “upper” and “lower” refer to the usual arrangement of the lid on top of the can. However, it goes without saying that the can lid according to the present invention may also be oriented in different ways or attached to the can if required.

[0089] The can lid 10 is a round, flat body with a radially circumferential bead 13 on its outside for reinforcement (see, for example, Figure 2). At its outer circumferential edge, the lid panel 12 may be crimped to the can body for connection, and thus for the production of a sealed can. The lid panel 12 may have external dimensions and material corresponding to conventional lid panels for beverage cans. Here, for example, the lid panel 12 is made from a metallic material such as tinplate or aluminum sheet and manufactured in a deep drawing and / or perforation process. On its upper and lower sides, the lid panel 12 is also coated with plastic.

[0090] The lid panel 12 also has a dispensing opening 14, which may be seen, for example, in Figure 7. The dispensing opening 14 is at least partially oval in shape. The contents of the can, such as a beverage, may be poured out through the dispensing opening when the can lid 10 is open.

[0091] Furthermore, the can lid 10 has an actuation element 16 located on the upper side of the lid panel 12. The can lid 10 has a closing element 18 located on the lower side of the lid panel 12. The closing element 18 is shown, for example, in Figure 3. The closing element 18 is movable between a closed position and an open position in a translational manner, substantially without rotation, and these positions correspond to the closed or open can lid 10. In its closed position, the closing element 18 closes the dispensing opening 14 in an airtight and liquidtight manner. In particular, the closing element 18 covers the dispensing opening 14 in the closed position, thereby sealing it from the inside to the interior of the can. In its open position, the closing element 18 at least partially decovers the dispensing opening 14.

[0092] In this invention, the actuation element 16 and the closing element 18 are made from a metal material. For example, the actuation element 16 and the closing element 18 may be made from the same material as the lid panel 12. Preferably, the actuation element 16 and the closing element 18 also have plastic coatings on their upper and lower sides. Alternatively, the closing element 18 and / or the actuation element 16 may be formed from plastic, for example, by injection molding.

[0093] The actuating element 16 is connected to the closing element 18. The movement of the actuating element 16 may therefore cause the closing element 18 to move between a closed position and an open position, particularly in an induced manner. As an example, one type of induction will be described below. Preferably, the connection is formed as a rivet connection, as shown here and described in more detail below. Alternatively, the connection may be, for example, a welded connection.

[0094] The actuation element 16 has a handle section 20 and a fastening section 22. The actuation element 16 is integrally formed from a metal plate. The handle section 20 and the fastening section 22 are connected by a film hinge 24 acting as a joint. The film hinge 24 allows rotation of the handle section 20 relative to the fastening section 22 about its longitudinal axis. Here, the film hinge 24 is formed by local damping within the actuation element, for example, by a notch.

[0095] In Figure 2, a schematic perspective view shows the handle section 20 partially rotated upward from its starting position shown in Figure 1 relative to the fastening section 22. At its end, facing outward from the fastening section 22, the handle section 20 has a region 30 with a smaller thickness. This makes it particularly easy to lift the handle section 20 from its starting position, for example, with a fingernail. In the starting position (Figure 1), the handle section extends substantially parallel to the lid panel 12 and is positioned substantially flat with respect to it.

[0096] Figure 4 is a schematic perspective view showing the operating position of the handle section 20. In this position, the handle section 20 is rotated far upward with respect to the plane defined by the fastening section 22 and / or the lid panel, for example, by at least 60° or at least 80°. As a result, the handle section 20 may be particularly easy to grip, for example, with two fingers, to shift the closing element 18. On its upper side, the handle section 20 also has a recess 26 (see Figure 1) which may provide an additional grip for the fingers (particularly the thumb) during repositioning.

[0097] On the lower side, the actuation element 16 has a locking section 28. This locking section is also formed integrally with the rest of the actuation element 16 from a metal plate. For example, the metal plate may be bent (in particular, folded) within the section 30 to form a second layer of material on the actuation element 16. The second layer of material forming the locking section 28 may also be considered part of the handle section 20. The two layers of material can reinforce the handle section 20 and allow for higher actuation force without causing damage. The bending also allows a thin edge region 30 to be economically formed in a single manufacturing step. The locking section 28 is held in place by the rounded edge of the handle section 20 in a further section 29, which also avoids a sharp outer edge.

[0098] The locking section 28 has a locking element 32 that protrudes from below. Here, the locking element 32 is configured as a hook, which can be seen particularly clearly in the side view of Figure 3. In the starting position, the locking element 32 extends into the corresponding recess 34 of the closing element 18 so that the handle section 20 can be positioned flat and the hook can engage with the rear of the lid panel 12. The handle section 20 is therefore locked in the starting position.

[0099] When the handle section 20 is lifted, the locking element 32 may deform plastically and thus detach itself from the lid panel 12. In this way, it is possible to provide a tamper-evident feature that can be used to identify the initial opening of the can. After the initial lift, the plastic deformation may prevent re-locking. The release of the locking element 32 may produce noise, which may also be perceived by the user as a signal. In another embodiment, the locking element 32 may deform substantially only elastically when the can is first opened. This allows the locking element 32 to re-lock on the lid panel when the handle section 20 is repositioned to return, for example, by a snap-in and / or snap-on connection. Thus, a transport lock may be provided even after the initial opening. This re-locking may also produce noise, which signals the re-locking to the user.

[0100] In the embodiments shown, the actuation element 16 is preferably configured to deform after the handle section 20 has been moved from its initial position. This can prevent the handle section 20 from being repositioned to return to its initial position and / or indicate that the handle section 20 has been initially opened. For example, the film hinge 24 may deform and / or tear at its outer edge so that the handle section 20 no longer remains in its initial position and / or so that the deformation and / or tearing is evident to the user. For example, the handle section may return only to an intermediate position after the initial opening, as shown in Figures 2 and 3. Advantageously, reverse bending of the handle section 20 is further prevented by the fact that downward rotation beyond the lid panel 12 would be necessary to reverse the plastic deformation, but is blocked thereby by the lid panel 12 due to the mounting of the actuation element 16. Preferably, the locking section 28 does not extend to the film hinge 24. This can facilitate the corresponding deformation as evidence of tampering. The starting position may correspond to the storage position of the handle section 20 prior to the initial opening.

[0101] Figure 5 again shows a schematic side view of the handle section 20 in its operating position. As in Figure 3, the lid panel 12 is not shown. Figure 6 shows a schematic top view of the can lid 10, with the handle section 20 in the operating position, but the can lid 10, and therefore the operating element 16 and closing element 18 (not visible in Figure 6), are also still in the closed position. In Figure 7, on the other hand, the can lid 10, and therefore the operating element 16 and closing element 18, are also in the open position. For this purpose, the operating element 16, and therefore the closing element 18, are also pulled and / or pushed upward in the image planes of Figures 6 and 7. Conversely, to reseal, the operating element 16, and therefore the closing element 18, may also be pulled and / or pushed downward in the image planes of Figures 6 and 7.

[0102] Figure 8A shows the lid panel 12 in a schematic top view, with the actuation element 16 and closing element 18 not shown. The lid panel 12 has an additional passage area in addition to the dispensing opening 14 in the form of an extension guide slot 34. The connection between the actuation element 16 and the closing element 18 is located within the guide slot 34, thereby guiding the displacement of the closing element 18 between the closed and open positions. Furthermore, the locking element 32 is also located within the guide slot 34 before the can is first opened.

[0103] In the embodiment shown, the dispensing opening 14 and the guide slot 34 are formed as a common through-opening within the lid panel 12, which allows them to be manufactured together at low cost, for example, in a perforation process. In its end region 36, facing outward from the dispensing opening 14, the can lid 12 has two relief notches 38, extending longitudinally and substantially transversely from the guide slot 34. As a result, the corners within the end region 36 of the guide slot 34 are rounded, which resists tearing caused by internal pressure within the can.

[0104] The lid panel 12 may further have a configuration that can provide equal pressure when the can is opened. For example, as shown in Figure 8B, the notch 40 may optionally be positioned adjacent to the dispensing opening 14 in a region far from the direction of movement of the actuation element 16 from the closed position to the open position. The notch may form a narrow channel between the inside and outside of the can prior to the actual uncovering of the dispensing opening 14. Due to the excessive pressure inside the can, a distinctly different hissing sound may be generated, which signals to the user that the beverage is not fresh.

[0105] As an alternative to the notch, an additional through-opening 42 with a smaller diameter may be optionally placed within the region, as shown in Figure 8C, to also de-cover a channel with a smaller cross-section prior to the actual de-covering of the dispensing opening 14 during opening. The through-opening 42 may also be referred to as a pressure equalization opening. This may also acoustically signal to the user excessive pressure, and therefore the freshness of the contents of the can.

[0106] In Figure 9A, the lid 10 of the can is shown in a bottom view with a closing element 18 in the closed position. The closing element 18 covers the dispensing opening 14. In Figure 9B, the closing element 18 is shown in the open position. The dispensing opening 14 is mostly uncovered. In particular, the dispensing opening 14 is uncovered so that a drinking straw (not shown) can pass directly through the dispensing opening 14 into the can.

[0107] Figure 10 shows a further top view of the can lid 10.

[0108] Figure 11 is a schematic side view showing the can lid 10 as shown in Figure 10. Figure 12 corresponds to a cross-sectional view along line BB as shown in Figure 10.

[0109] In Figure 12, it can be seen that the seal 44 is positioned on the closing element 18 in the upper groove and faces the lid panel 12. The seal 44 can also be seen in Figures 3 and 5. The closing element 18 is connected to an actuating element 16 such that the seal 44 is pressed against the underside of the lid panel 12, and thus seals the dispensing opening 14 in the closed position. For this purpose, the actuating element 16 may be stationary on the upper side of the lid panel 12 with only its curved edge 46, and thus easily pre-loaded. For example, the actuating element may be substantially straight in the unconnected state and may be bent toward the closing element 18 when connected. Alternatively, the closing element, in particular its underside, may be cambered in the unconnected state, and in particular, concavely cambered.

[0110] Within the area of ​​the film hinge 24, the closing element 18 has a region 49 that abuts against the lid panel 12. This region can support the operating element 18, in particular the film hinge 24, and the lid panel 12 when the handle section 20 is pivoted. In this way, overloading and unwanted deformation of the lid panel 12 can be prevented. Alternatively, or in addition, the closing element 18 may abut against the lid panel along a central region 47.

[0111] In another aspect, the closing element 18 includes individual recesses 48. These recesses 48 may provide additional air channels between the inside of the can and the atmosphere when in the open position. Air may flow back through the air channels during dispensing, enabling rapid and uniform dispensing. For example, the inlet for the air channel may be formed by an opening between the actuating element 16 and the closing element 18. In the closed position, this opening is blocked by the lid panel 12. Moving this inlet into the area of ​​the dispensing opening 14 opens a gap between the actuating element 16 and the closing element 18 through which air can flow.

[0112] The opening may be defaced as an outlet for an air channel by deflecting the closing element 18 in the circumferential bead 13 of the lid panel 12, thereby separating it from the underside of the lid panel. The closing element 18 and / or the lid panel 12 may also deform elastically and release the gap. The closing element may rotate slightly downward within the end region, so to speak. Alternatively, within the lid panel 12, recesses 50 in the form of embossing may be positioned downward in the direction of the can interior within this region (not shown), which may also result in such segment-by-segment deflection of the closing element 18 from the lid panel 12.

[0113] Alternatively, one or more ridges 50 may be formed on the lid panel 12 in an upward direction. This also allows for the opening of at least one passage for an air channel in the open position. In this modification, the lid panel 12 is particularly resistant to deformation due to internal can pressure. Figure 8A illustrates four ridges 50 by dashed lines as an example. These ridges may be produced as embossing.

[0114] Figure 13 shows a cross-sectional view of the can lid 10 along line CC, and Figure 14 shows one along line AA. Here, the connection of the actuator 16 to the closing element 18 is particularly visible. The connection does not penetrate the closing element 18. Instead, the closing element 18 has a rivet ripple 52 that protrudes upward from the closing element 18 and is at least partially located within the guide slot 34. The rivet ripple 52 extends upward through a rivet opening in the actuator 16 and is fastened thereby by riveting. The actuator 16 engages at least partially behind the rivet ripple 52.

[0115] The rivet opening of the actuation element 16 is located within a recess 54 of the actuation element 16 formed in a downward direction. The recess 54 may also preferably be considered a projection that protrudes downward toward the lid panel 12. The recess 54 may extend into the guide slot 34 and be supported against the edge of the guide slot 34 formed by the lid panel 12 to guide the repositioning movement between the closed and open positions. The recess 54 allows the rivet connection, and therefore the can lid 10, to also have a low overall height. In particular, the rivet connection should therefore have a height only slightly greater than the conventional riveting of the lid panel to the metal tab of a conventional can, which is not resealable. As a result, conventional machinery and processes may also be used for the can lid 10. In particular, the rivet connection should have only the thickness of the actuation element 16 and the closing element 18, and not the thickness of the materials of the lid panel 12, actuation element 16, and closing element 18.

[0116] The recess 54 may also provide anti-torsion protection. For this purpose, the recess 54 has, among other things, two substantially planar surfaces 56, as can be seen in Figure 10. For example, the planar surfaces 56 extend substantially parallel to the edge of the lid panel 12 that demarcates the guide slot 34. The planar surfaces 56 support the main edge as the actuation element 16 is displaced along the guide slot 34, thereby preventing unwanted rotation of the actuation element 16.

[0117] In the cross-sectional view along line AA shown in Figure 14, the double layer of material of the actuation element 16 within the area of ​​the handle section 20 is particularly clearly visible. In addition, it is easily discernible that the locking element 32 engages with the rear of the lid panel 12. Figure 14 also shows that in this embodiment, the handle section 20 is slightly inclined toward the fastening section 22 toward the lid panel 12 before it is first opened, and that it fits tightly therein due to the locking.

[0118] Figure 15 shows a particularly advantageous cross-sectional configuration of the seal 44 in a cross-sectional view. It is shown that the seal 44 is at least partially received within the groove 58 of the closing element 18. The seal 44 has an upper seal edge 60 that contacts the lower side of the lid panel 12. The seal edge 60 is preferably inclined. In particular, the seal edge 60 may extend radially inward from the groove 58 and / or be inclined radially inward. Below the seal edge 60, and radially inward thereof, the latter has an undercut 62. When the seal edge 60 is pressed more forcefully, for example due to increased internal can pressure, the seal edge may be redirected into this gap. Thus, fluctuating pressure can be compensated without damaging the seal 44. In addition, due to friction between the seal 44 and the lid panel 12, the operating force may fluctuate, though not as strongly, along with the internal can pressure. A gap 64 not occupied by the seal 44 is preferably provided within the groove 58, extending radially outward. This allows for compensatory movement of the seal edge 60 in response to movement to the left in the image plane of Figure 15, thereby protecting the seal edge 60 from damage during repeated opening and closing of the can lid 10.

[0119] Figure 12-14 shows that, as a further option, the seal 44 may be tightened into the groove 58 using a folded edge 45, and / or the groove may be formed by such a fold. In this way, the outer edge of the closing element 18 is sealed by the seal 44. This edge may not be coated with plastic, for example. In this way, it is possible to prevent metal particles from entering the contents of the can and / or corrosion of the edge, in particular by preventing contact with the contents of the can. Furthermore, the seal 44 is simply and securely held.

[0120] Figure 16 again illustrates the shape of the closing element 18 before it is connected to the seal 44 in an exploded view. This shows a rivet ripple 52 surrounded by a central region 47. At least a portion of the central region, or its entire circumference as shown in Figure 16, is surrounded by a recess 48, which also forms an air channel. A raised portion 49 surrounding at least a portion of the recess 48, or its entire circumference as shown in Figure 16, is provided, and the raised portion 49 may support the lid panel 12 and support the hinge 24. The closing element 18 is preferably rotationally symmetric to facilitate manufacturing.

[0121] Figures 17 and 18 further illustrate further optional features and embodiments of the lid panel 12, which may be used in combination with any of the lid panels 12 described above. Here, the lid panel 12 has at least one or more first recesses 50A that can form a second open end of the air channel 48 during and / or in the open position of the closure element 20, as described above.

[0122] At least one first recess 50A is preferably positioned within the seal 49 in the closed position of the closing element 18 (see Figures 16 and 19).

[0123] At least one first recess 50A is positioned to cover, preferably completely cover, the closure element 18 (not shown in Figures 17 and 18) and / or the operating element 16 in the closed position.

[0124] When the closing element 20 is repositioned from the closed position to the open position, it preferably reaches a position in which the seal 50 and / or the closing element 20 partially overlap with at least one first recess 50A, particularly an intermediate position. In this way, pressure equalization, particularly initial pressure equalization, can be achieved when the closing element 18 is opened. At least one first recess 50A may be positioned so that, in the open position, it is completely overlapped by the closing element 18 and / or is completely located within the seal 44.

[0125] In combination with or independently of at least one first recess 50A, the lid panel 12 may have at least one second recess 50B. This is preferably positioned so as not to be covered by the closing element 18 in the closed position and / or not to be located within the seal 44 even partially in the closed position. Preferably, at least one second recess 50B is not obscured by the actuation element 16 in the closed position. In the open position, at least one second recess is preferably partially (in particular, only partially) overlapped by the closing element 20 and / or the seal 50 and / or the actuation element 16. In the closed position, the second recess 50B may thus provide an alternative open second end for the air channel 48. The use of different recesses 50A, 50B allows for selective adjustment of the airflow through the air channel 48. For example, at least one first recess may be sized to produce a hissing sound in response to opening. For example, at least one second recess 50B may be sized to prevent gurgling noises during dispensing, in particular when the closing element 18 is fully open.

[0126] The second recess 50B may be formed as one or more recesses 50B located, for example, behind the actuation element 30 (see Figure 17) and / or next to the actuation element 16 in the direction of the actuation element 16's displacement (see Figure 18).

[0127] At least one first recess 50A and / or at least one second recess 50B may protrude upward or downward. At least one first recess 50A and / or at least one second recess 50B may be formed as an embossing on the lid panel 12 in particular.

[0128] In combination with, or independently of, at least one first recess 50A and / or at least one second recess 50B, the lid panel 12 may further comprise one or more (in particular, two) third recesses 51. These may cooperate with one or more corresponding projections 73 on the upper side of the closure element 18 (see Figure 21) to provide longitudinal guides and / or anti-twist protection for the closure element 18. In this respect, the recesses 51 preferably project upward. These may be formed as embossings on the lid panel 12.

[0129] Figure 19 shows a further embodiment of the closing element 18 and illustrates several further optional features. In particular, the closing element here has a first contact region 49A and a second contact region 49B, both of which project upward from the closing element 18. They serve to support the hinge. Independent of the contact regions 49A, 49B, the closing element may further include a recess for receiving a locking element, provided in the shown embodiment as a recess 74 in addition to the air channel 48. Also, as can be seen, the closing element 18 does not need to be rotationally symmetric.

[0130] Can lids and cans are described above, but the disclosed closing devices may also be attached to other containers for liquids. Such containers for liquids may be made from, for example, cardboard, plastic, and / or metal. This applies in particular to containers made from a material that is sufficiently rigid, at least in the area of ​​the dispensing opening. In the case of liquid containers, the lid panels described herein may be replaced by, for example, a container wall, and / or formed by such a wall.
