Definitions

  • the present invention relates to a can lid.
  • the invention also relates to a can and a method for producing a can lid.
  • Beverage cans with a cylindrical container made of aluminum or tinplate are known.
  • a lid is crimped on to which a metal tab is riveted as an opener.
  • a scratched oval line is broken open and part of the lid is pressed into the inside of the can to reveal a drinking opening.
  • the disadvantage here is that the beverage can cannot be closed again. As a result, a drink in it quickly becomes stale. In addition, the beverage can easily be spilled during further transport.
  • Resealable can lids are also known.
  • EP 2 614 010 B1 describes a can lid in which a closure element on the underside can be pivoted between a closed position and an open position by an actuation element on the top side.
  • the closure element and the actuating element are large components, which is disadvantageous when filling.
  • the can lid is so heavy and expensive.
  • the rotary movement also requires high actuation forces and places an unfavorable load on the components, for example with a strong shear force.
  • the object of the present invention is to improve a can lid, which is reclosable. Furthermore, it is an object of the invention to improve a method for producing a reclosable can lid and a reclosable can.
  • a first aspect relates to a can lid for a can.
  • the can preferably be designed as a beverage can and / or as a storage container for bulk material.
  • the can lid can have at least one lid mirror, which is designed to limit an upper side of the can, preferably by crimping an outer circumferential edge of the lid mirror with a side wall of the can.
  • the lid mirror can correspond, for example, to a lid of conventional beverage cans.
  • the cover mirror can be made of aluminum or white bleach, optionally with a plastic coating, for example as corrosion protection.
  • the lid mirror can have at least one pouring opening through which a substance in the can can be poured out.
  • the pouring opening is preferably always provided in the lid mirror.
  • the pouring opening is not, as is usual with beverage cans, only opened by a metal tab when it is opened for the first time.
  • the can lid can have an actuating element which is arranged on an upper side of the lid mirror, which faces away from an interior of the can when the can lid is attached to it.
  • the can lid can have a closure element, which is arranged on an underside of the lid mirror, which faces an interior of the can when the can lid is attached to it.
  • the closure element can be displaceable in a substantially translatory manner along the cover mirror by means of the actuating element between a closed position in which the closure element closes the pouring opening in a fluid-tight and / or gas-tight manner and an open position in which the pouring opening is at least partially exposed.
  • the translational movement is very intuitive, places little stress on a connection between the closure element and the actuating element and requires low actuating forces.
  • the closure element is preferably not flat on its lower and / or upper side.
  • the closure element can have one or more cutouts or one or more projecting areas on its lower and / or upper side.
  • Such a recess can be formed, for example, in the area of a connection to the actuating element.
  • several ribs can be provided on the underside.
  • the closure element and the actuating element are fastened to one another by means of a connection.
  • the connection is preferably fixed and / or its length is not variable. In other words, the distance between the actuating element and the closure element in the region of the connection is preferably fixed and / or not variable. This enables, among other things, an automatic adjustment of the contact pressure of the closure element to the lid, which is discussed in more detail below.
  • the closure element and the actuating element are preferably fastened to one another by means of a connection which does not penetrate the closure element. This way, the contents of the can are reliably protected. In particular, undesirable leakages can be excluded with the lid closed.
  • a connection is advantageous since a through opening for connection can only be sealed with great effort and tends to leak under pressure.
  • a welded joint is particularly suitable because a small amount of material is required.
  • the actuation element and the closure element can be attached to one another using ultrasound or friction welding, in particular when using plastics to produce the closure element and / or the actuation element.
  • connection When the closure element is moved from the closed position into the open position, the connection can be moved along a guide slot in the cover mirror.
  • the connection in particular a welding area, can thus be arranged in a plane defined by the cover mirror.
  • the connection can penetrate the cover mirror, that is to say it can be arranged in a through opening of the cover mirror.
  • the connection can serve as a guide.
  • the overall height of the can lid can be particularly flat, which results in advantages when filling. For example, the height determines how many can lids can be provided in a magazine. Thin reclosable can lids allow similar magazine fillings as non-reclosable can lids, which means that the production rate is the same or only slightly lower than that of non-reclosable cans on the same filling line.
  • the actuating element can have a fastening section which has the connection to the closure element.
  • the actuating element can advantageously be connected to the closure element without the design of others Sections of the actuator is restricted.
  • other sections of the actuating element can be designed to be moved, in particular pivoted, relative to the fastening section and thus relative to the connection to the closure element.
  • the actuating element can have a locking section, by means of which the actuating element is locked in the closed position on the cover mirror at least before an initial adjustment from the closed position to the open position.
  • the lock can be used to provide a transport lock. With the locking an unwanted opening of the box or an adjustment of the closure element from the closed position to the open position can be reliably prevented.
  • the locking section can also be designed as a tamper-evident feature, which can indicate to a user that the can lid has been opened for the first time. This ensures a hygienically perfect can content.
  • the actuating element can have a grip section which is designed for gripping for the purpose of adjustment between the open position and the closed position. The grip section can thus be designed independently of the locking section and / or the fastening section, as a result of which this can be particularly ergonomic. This makes it easier to operate, i.e. close and open, the can lid.
  • the fastening section can be connected to the handle section and / or to the locking section via a first joint which has a first joint axis.
  • the locking section can be connected to the handle section and / or to the fastening section via a second joint which has a second joint axis. This enables the movement of the handle section to be coupled to the locking section. For example, pivoting the handle section into an actuating position can simultaneously cause the locking section to pivot, so that a locking is released.
  • a movement of the grip section can be decoupled from the locking section in a certain pivoting range. For example, the grip section can be raised slightly without the locking section being lifted as well. This can break a seal of authenticity, for example. In addition, an unintentional release of the locking device can be avoided.
  • the lid mirror 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 mirror, apart from through openings, can correspond to a standardized lid mirror of beverage cans, in particular a B64 or CDL lid mirror.
  • the B64 cover mirror can be of the type 200, 202, 204, 206 or 209, for example.
  • the CDL lid mirror can be of type 200 or 202, for example.
  • the cover mirror can be essentially flat and / or round, preferably circular.
  • the cover mirror can have a circumferential bead, which increases its stability and helps in forming the folded edge.
  • the lid mirror can also be called a shell.
  • All metallic parts of the can lid are preferably coated with plastic or covered with a plastic film on the flat side facing a storage space of the can, preferably also on the flat side facing away. This serves to protect against corrosion and to protect the substance stored in the can. For example, dissolving of metal by a liquid in the can can be prevented in this way. In this way, for example, it can also be prevented that metal particles get into a drink.
  • Such a coating can be dispensed with in the case of parts which are formed from plastic. As a result, these parts are inexpensive to manufacture, robust and easy to recycle.
  • respective plastic parts can consist of only one material.
  • the closure element can be essentially flat and / or round
  • the can for which the can lid is provided is preferably intended for storing a drink, a soup or a bulk material.
  • the drink may contain fibers such as pulp in an orange juice.
  • the bulk material can be a spice, for example. Soup can, for example, have piece goods such as pasta, pieces of meat, etc.
  • the pouring opening is preferably large enough to be able to pour it out.
  • the closure element can open a pouring opening in the open position, which is larger than solid bodies in the can.
  • the pouring opening can be a through opening from an interior to the outside of the can.
  • a cross-sectional area of the pouring opening is preferably at least 1.5 cm 2 , more preferably at least 1.8 cm and very preferably at least 2 cm.
  • the pouring opening preferably has an oval, circular or crescent shape.
  • An edge region of the pouring opening which is front in the longitudinal direction of the guide slot and a rear area in the longitudinal direction of the guide slot, is preferably arcuate and / or curved. Both a front edge area and a rear edge area are preferably curved in the same direction.
  • the cover mirror at the edge region of the pouring opening, on which the guide slot is arranged preferably forms two tongues projecting into the pouring opening. Through these tongues, the connection can be made in a foremost position of the closure element.
  • the guide slot can be a through opening in the cover mirror.
  • the guide slot is preferably designed as an elongated opening.
  • a width of the guide slot can be made substantially constant over its length.
  • the guide slot can specify the translational movement of the closure element and the actuating element between the closed position and the open position. At least a partial area of the closure element and / or the actuating element can be guided through the guide slot, for example in that this partial area bears against an edge of the cover mirror delimiting the guide slot.
  • Respective lateral walls of the guide slot which preferably form a radially inner edge of the cover mirror and / or are an edge of the cover mirror, can therefore form a guide.
  • the pouring opening and / or the guide slot are preferably punched out. It can be punched through areas in the lid mirror.
  • the closure element can seal the interior from the pouring opening in the closed position, for example by means of a seal and / or by pressing it onto the cover mirror. This pressing can be effected by a pretension and / or the connection to the actuating element.
  • the actuating element can move together with the closure element, that is to say also preferably guided essentially translationally along the cover mirror. Through their connection, for example through the welded connection, the actuating element and the closure element are permanently connected to one another during normal use. When used as intended, such as opening and closing the can, it is preferably not provided that the actuating element and the closure element are separated from one another.
  • connection can be designed for this purpose, the actuating element and the closure element to hold on the lid mirror.
  • the connection is preferably under a prestress.
  • the actuating element can be cambered by the pretension.
  • the crowning is preferably designed in one direction, which is reduced by an increased internal pressure and / or pressing on the actuating element. This makes opening easier.
  • the closure element In the closed position, the closure element preferably covers the pouring opening and the guide slot in a gas-tight and / or fluid-tight manner.
  • the closure element preferably extends further over the lid mirror as a pouring opening and a guide slot.
  • Respective outer edges of the closure element are preferably arranged radially outside respective through openings in the cover mirror in the closed position.
  • a diameter and / or a length of the closure element in particular a diameter and / or a length of an area surrounded by a seal of the closure element, is preferably greater than a length between a front point of the pouring opening, in particular an apex of the pouring opening, and an opposite rear one End of the guide slot.
  • the actuating element preferably extends further over the lid mirror as a pouring opening and guide slot together, in particular in the closed position.
  • the actuating element In the closed position, the actuating element preferably covers the pouring opening and the guide slot. This can prevent contamination from accumulating on the closure element, in the guide slot and / or in the pouring opening.
  • the closure element is preferably designed such that it completely overlaps the pouring opening and / or the guide slot in the closed position. In the open position, the closure element releases at least 50%, preferably at least 70% and more preferably at least 90%, of the area of the exit opening.
  • the contents of the can are therefore directly accessible through the surface, for example via a straw. That is, a straight straw can be passed through the exit opening in the entire non-overlapping area along the line of sight (vertical direction of the can) without bending or kinking. This corresponds to the manner known to the consumer with conventional beverage cans. This can also make it easier to dispense liquids with fibers or piece goods.
  • the top of the can lid and / or respective parts can also be referred to as the outside.
  • the underside can also be referred to as the inside.
  • Actuating element at least partially formed by a projection on the closure element and / or the actuating element.
  • This projection extends at least partially through the guide slot, for example in the open position and / or in the closed position.
  • the projection preferably extends at least partially through the guide slot in the open position and in the closed position.
  • the lead can also serve as part of the tour. In addition, this preferably provides a securing of the actuating element against rotation.
  • the projection In the closed position, the projection can also at least partially extend through the pouring opening.
  • the grip section is preferably between a stowed position in which the grip section is essentially parallel to the cover mirror and / or the
  • Fastening section is arranged, and an actuating position in which the handle section for adjustment between the open position and the closed position can be gripped.
  • the handle section is preferably pivotable upward, in particular essentially pivotable upward only from its stowed position.
  • the handle section can be pivoted from the stowed position into the actuating position, preferably against the direction of displacement, in which the closure element can be displaced from the closed position into the open position.
  • the stacking height of the can lid when filling is particularly low, but the handle section is still easy to grip when pressed.
  • the grip section is preferably flat and, in the stowed position in the direction perpendicular to the cover mirror, is less than 3 mm, preferably less than 2 mm, thick.
  • An upper side of the handle section is preferably essentially flat. In the stowed position, the upper side of the fastening section and the upper side of the handle section essentially form a plane. When the handle portion is in the stowed position, the actuator can be substantially planar. When moving from the stowed position to the actuating position, the handle section is preferably pivoted upwards. In particular, a rear end region of the handle section, which is the most distant from the pouring opening, is pivoted upward. In the stowed position, the underside of the handle section is preferably spaced at least in sections from the top of the cover mirror. As a result, the grip section can easily be raised with a finger, for example by means of the fingernail.
  • the underside of the handle section is preferably at least in sections, and preferably completely, spaced from the top of the cover mirror.
  • the grip section can thereby be at least partially encompassed, for example with two fingers, so that force can be exerted in a direction parallel to the top of the cover mirror.
  • a pivoting of the handle section can be a folding up, preferably folding up by an angle of at least 30 °, preferably at least 45 °, particularly preferably at least 60 °.
  • the grip section is preferably pivoted upward from the closed position into the open position against the direction of movement of the actuating element and / or the closure element.
  • the grip section can be designed to be pivoted about the first hinge axis for adjustment between the stowed position and the actuating position relative to the fastening section.
  • the joint facilitates the actuation of the actuating element, in particular the pivoting of the handle section.
  • the closure element and / or the actuating element are preferably each formed from a plastic.
  • the closure element and / or the actuating element can each consist of a plastic.
  • the two joints and respective sections of the actuating element can thus be manufactured in a particularly simple manner, in particular in one piece in an injection molding process.
  • the closure element can thus withstand a can content without additional measures, such as coatings.
  • the can lid can be particularly light.
  • the first joint and / or the second joint are preferably designed as a film hinge. Accordingly, the two joints can also be referred to as the first film hinge and the second film hinge.
  • Film hinges are particularly easy to manufacture for plastic parts, in particular in one piece with other sections.
  • the film hinge can be formed by an area in the actuating element with a smaller overall thickness, in particular in the form of a notch, which can be produced, for example, by injection molding, embossing or scratching.
  • a film hinge is robust, but requires low actuation forces for the relative pivoting of the respective sections connected to it.
  • the film hinge can also have the advantage that it permanently deforms and the handle section remains in the actuating position after pivoting against gravity.
  • the first joint is preferably formed by a notch which extends downward from an upper surface of the actuating element into the actuating element.
  • An initial position can thereby be defined, in which the grip section extends essentially parallel to the cover mirror.
  • a region of the underside of the handle section, which is adjacent to the first joint can form a plane with the adjoining region of the underside of the fastening section via the first joint.
  • a notch can be a particularly simple form of a film hinge.
  • the two notch surfaces of the first joint on the upper side of the actuating element can also define an actuating position of the handle section and / or a maximum pivoting angle relative to the fastening section. In this position, the two notch surfaces lie against each other. The two notch surfaces can thus form a stop on the first joint. In the case of notch surfaces which abut one another, the respective actuation forces can be supported particularly well and directed to the closure element, as a result of which the can lid is particularly robust.
  • the second joint is preferably formed by a notch which extends upwards from a lower surface of the actuating element into the actuating element. This allows a locking position to be defined in which the locking section extends essentially parallel to the cover mirror. In this position, an area of the upper side of the locking section, which is adjacent to the second joint, can form a plane with the adjoining area of the upper side of the handle section via the second joint.
  • a notch can be a particularly simple form of a film hinge.
  • the two notch surfaces of the second joint on the underside of the actuating element can also define a coupling position of the locking section or a maximum pivoting angle relative to the handle section. In this position, the two notch surfaces lie against each other.
  • the two notch surfaces can thus form a stop for the second joint.

By moving this inlet into the area of the pouring opening 14, a gap between the actuating element 16 and the closure element 18 is created, through which air can flow.
  • an opening can be opened by the
  • Closure element 18 is deflected on the circumferential bead 13 of the cover mirror 12 and is thus spaced from the underside of the cover mirror 12.
  • the closure element 18 can have an edge-side projection 84 on a side facing away from the pouring opening 14.
  • the closure element 18 and / or the cover mirror 12 can deform elastically in order to also open a gap.
  • the closure element can rotate slightly downward in an end region. This rotation can be recognized particularly well in FIG. 8e.
  • a depression 50 in the form of an embossing in the direction of the inside of the can can be arranged in this area in the cover mirror 12 (not shown), which can likewise cause the closure element 18 to be deflected in this way from the cover mirror 12.
  • one or more bulges 50 can be formed in the upward direction in the cover mirror 12, which likewise means that at least one passage for the air duct can be released in the open position.
  • the lid mirror 12 is particularly resistant to deformation due to internal pressure in the can.
  • Fig. 13a four bulges 50 are illustrated by dashed lines as an example. These can be made as embossments. Further possible configurations are discussed in more detail below with reference to FIGS. 15 and 16.
  • the adjustment of the can lid 10 from its closed position to the open position will be explained again.
  • 8a the can lid 10 is closed.
  • the grip section 20 and the locking section 28 essentially abut the top of the cover mirror 12.
  • the locking element 32 is located in the guide slot 34 and preferably in a recess 45 on the upper side of the closure element 18 and / or in the recess 48.
  • the locking element 32 is in engagement with the cover mirror 12.
  • FIG. 8b the grip section 20 has been raised and pivoted about the hinge axis of the first film hinge 24. However, the locking element 32 is still in engagement with the cover mirror 12. As a result, the web elements 72 are broken.
  • the edge-side projection 84 on the bead 13 was deflected downward, whereby the air channel between the closure element 18 and the cover mirror 12 was released. This allows air to flow particularly easily into the interior of the can when pouring out, which makes pouring out particularly quick and smooth.
  • the actuating element 16 and thus the closure element in the image plane of FIG. 8 is moved to the left, whereby the pouring opening 14 is closed again.
  • a downwardly projecting rectangular wall 86 can be seen on the underside of the actuating element 16.
  • This wall 86 is when connecting the Actuating element 16 with the closure element 18 is preferably at least partially melted by means of ultrasonic welding. The resulting connection is particularly strong.
  • the closure element 18 has a groove 88 in its upper side corresponding to the wall 86. Molten material during ultrasonic welding can flow into this groove 88 and improve the strength of the connection between the actuating element 16 and the closure element 18.
  • a projection 90 is provided in the center of the groove 88 and can protrude upward.
  • the projection 90 can, for example, be tapered to the top, in particular roof-shaped. This projection 90 can also be at least partially melted during ultrasonic welding. Overall, there is an entanglement of wall 86, groove 88 and projection 90, which results in a particularly firm connection.
  • the closure element 18 can have a rib structure on its underside with ribs and depressions arranged between them. As a result, the closure element 18 can be stiffened while saving weight and material.
  • the closure element 18 is preferably free of a rib structure. This provides a favorable contact surface for an ultrasonic welding probe.
  • FIG. 11 shows that the actuating element 16 can have a rib structure similar to that with ribs and interposed depressions like the closure element 18 on its underside.
  • This rib structure is also preferably not provided in the area of the connection, in particular the wall 86.
  • connection of the closure element 18 with the actuation element 16 does not penetrate the closure element 18.
  • the connection of the closure element 18 with the actuation element 16 is at least partially arranged in the guide slot 34. Due to the rectangular shape of the connection, predetermined for example by the shape of the wall 86, the groove 88 and / or the projection 90, the connection for guiding the adjustment movement between the closed position and the open position can be supported on the edge of the guide slot 34 formed by the cover mirror 12. Due to its rectangular shape, the connection can also provide an anti-rotation device.
  • the connection thus has two essentially flat surfaces. The flat surfaces extend, for example, essentially parallel to the edge of the cover mirror 12, which delimits the guide slot 34. The flat surfaces can be supported on this edge when the actuating element 16 is moved along the guide slot 34 and thus prevent undesired rotation of the actuating element 16.
  • the seal 44 shows a particularly advantageous cross-sectional configuration of the seal 44 in a sectional view. It can be seen that the seal 44 is at least partially received in a groove 58 of the closure element 18.
  • the seal 44 has a sealing lip 60 on the top side with which it contacts the cover mirror 12 on the underside.
  • the sealing lip 60 is preferably inclined.
  • the sealing lip 60 can extend radially inward from the groove 58 and / or be inclined radially inward. Below and radially inward to the sealing lip 60, the latter has an undercut 62. If the sealing lip 60 is pressed more strongly, for example due to an increased can pressure, the sealing lip can escape into this free space. Different pressures can thus be compensated for without damaging the seal 44.
  • an actuation force may vary less with the internal pressure of the can due to friction between the seal 44 and the lid mirror 12.
  • the cover mirror 12 here has at least one first depression 50A or a plurality of depressions 50A, which can form a second open end of the air duct 48 during the opening of the closure element 20 and / or in its open position, as already described above.
  • the at least one first depression 50A is preferably arranged such that it is arranged within the seal 49 (see FIGS. 16 and 19) in the closed position of the closure element 18.
  • the at least one first depression 50A is preferably arranged such that it is covered, preferably completely, in the closed position by the closure element 18 and / or by the actuating element 16 (not shown in FIGS. 15 and 16).
  • a position, in particular an intermediate position, is preferably achieved in which the seal 50 and / or the closure element 20 partially overlaps the at least one first depression 50A.
  • a pressure equalization can thus be achieved, in particular an initial pressure equalization when the closure element 18 is opened.
  • the at least one first depression 50A can be arranged such that it is completely overlapped by the closure element 18 in the open position and / or is arranged entirely within the seal 44.
  • the cover mirror 12 can have at least one second depression 50B. This is preferably arranged such that it is not covered by the closure element 18 in the closed position and / or is not arranged within the seal 44 in the closed position, not even partially.
  • the at least one second depression 50B is preferably not covered by the actuating element 16 in the closed position.
  • the at least one second recess is preferably partially (in particular only partially) overlapped by the closure element 20 and / or the seal 50 and / or the actuating element 16.
  • the second recess 50B can thus provide an alternative open second end for the air duct 48 in the closed position.
  • the use of different recesses 50A, 50B makes it possible to selectively adjust the air flow through the air duct 48.
  • the at least one first depression can e.g. be dimensioned so that there is a hiss when opened.
  • the at least one second recess 50B can e.g. be dimensioned such that gurgling is prevented during pouring, in particular when the closure element 18 is fully opened.
  • the second depression 50B can be formed, for example, as one or more depressions 50B, which is arranged in the direction of displacement of the actuating element 16 behind the operating element 30 (see FIG. 15) and / or next to the actuating element 16 (see FIG. 16).
  • the at least one first depression 50A and / or the at least one second depression 50B can protrude upwards or downwards.
  • the at least one first depression 50A and / or the at least one second depression 50B can in particular be designed as an embossing in the cover mirror 12.
  • the cover mirror 12 can furthermore have one or more (in particular two) third depressions 51. These can interact with one or more corresponding projections 73 on the upper side of the closure element 18 in order to provide a longitudinal guide and / or an anti-rotation device for the closure element 18.
  • the depression 51 preferably projects upwards. It can be designed as an embossing in the cover mirror 12.
  • the disclosed closure can also be attached to other containers for liquids.
  • liquid containers can be made of cardboard, plastic and / or metal, for example. This applies in particular to containers which are made at least in the region of a pouring opening from a material which has sufficient rigidity.
  • the lid mirror mentioned here can be replaced, for example, by a wall of the container and / or can be formed by such a wall.
