Definitions

  • the invention relates to a can closure, in particular for a milk can.
  • the invention further relates to a can lid with such a can closure and a can with such a can closure or a corresponding can lid.
  • Such a can closure is known, which can be inserted into an opening in a metal can lid of a beverage can (e.g. milk can).
  • This known can closure has an outer closure part and an inner closure part which, in the assembled state, are both inserted into an opening in the can lid and connected to one another, for example by a welded connection or an adhesive connection.
  • the outer closure part consists of a lower closure part and an upper closure part, the lower closure part being connected to the inner closure part, for example by a welded connection or an adhesive connection, as already mentioned above.
  • the upper closure part is connected to the lower closure part by a film hinge and can be pivoted from a delivery position into a use position.
  • the upper closure part In the delivery position, the upper closure part is pivoted away from the lower closure part and then lies flat on the can lid.
  • the upper part of the closure In the use position, however, the upper part of the closure is on the lower part pivoted and then rests on the lower closure part, a pouring opening extending through the inner closure part and through the lower closure part and the upper closure part.
  • a closure cover is also pivotably attached to the upper closure part by means of a further film hinge in order to be able to open and close the pouring opening.
  • the WO 2008/054 636 A2 shows a can closure with a massive closure part that forms a kind of pressure bulkhead. However, no tamper-evident element which can be broken open and closes the pouring opening is described there.
  • the invention is therefore based on the object of improving the known can closure described above accordingly.
  • the can closure according to the invention initially has, in accordance with the known can closure described at the beginning, a pouring opening through which liquid can be poured out of the can.
  • the can closure according to the invention in accordance with the known can closure described above, has a tamper-evident element which closes the pouring opening in the original state and can be broken open for pouring in order to release the pouring opening.
  • the consumer can therefore use the state of the tamper-evident element to recognize whether the can is in the closed original state or whether the can has already been opened in the meantime.
  • the can closure according to the invention is now characterized by an additional pressure bulkhead, which closes the pouring opening on the inside of the tamper-evident element and thereby keeps the pressure inside the can away from the tamper-evident element, whereby the pressure bulkhead can be broken open for pouring in order to release the pouring opening.
  • the pouring opening is closed by two separate components, namely on the one hand by the tamper-evident element known per se and on the other hand through the pressure bulkhead.
  • the pressure bulkhead only has the task of keeping the pressure inside the can away from the tamper-evident element so that the tamper-evident element is not broken out in the event of a high internal can pressure.
  • the pressure bulkhead therefore preferably has a significantly greater compressive strength with respect to the internal pressure of the can than the tamper-evident element.
  • the pressure bulkhead can have a pressure resistance of up to 2 bar, 3 bar, 4 bar, 5 bar, 6 bar or even 7 bar compared to the internal pressure in the can.
  • the pressure bulkhead is essentially disk-shaped and is inserted into the pouring opening in its original state, for example in the inner closure part or in the lower closure part of the outer closure part, if the can closure according to the invention is constructed in this way.
  • the pressure bulkhead preferably has a sealing lip running around the circumferential edge of the sealing bulkhead, which protrudes outwards (ie upwards) from the pressure bulkhead towards the outside of the can and is sealingly applied to a circumferential sealing surface on the inner wall of the pouring opening.
  • the sealing lip of the pressure bulkhead therefore leads to a good sealing effect.
  • the pressure bulkhead is preferably designed such that the sealing effect between the sealing lip of the pressure bulkhead on the one hand and the sealing surface of the can closure on the other hand improves with increasing can internal pressure.
  • This can be achieved, for example, in that the disc-shaped can closure bulges outwards when subjected to pressure from the internal pressure of the can, this bulging causing the protruding sealing lip to be pressed axially and radially outward against the circumferential sealing surface with its free end.
  • the contact pressure of the sealing lip on the sealing surface increases with the internal pressure of the can, so that the sealing effect improves with increasing internal pressure of the can.
  • the pressure scrap has a stiffening rib which is preferably attached to the outside of the pressure bulkhead and runs around it in a ring.
  • a projection can be located on the underside of the pivotable upper part of the closure in order to break out the tamper-evident element when the can closure is folded up.
  • this projection presses on the tamper-evident element and breaks it out of the pouring opening.
  • This projection is preferably adapted in its shape and position to the stiffening rib in the pressure bulkhead. In the folded state, the stiffening rib in the pressure bulkhead, on the one hand, and the projection on the underside of the upper part of the closure are therefore preferably in congruence on top of one another.
  • the upper closure part therefore preferably has at least one on its underside Projection which protrudes downwards and facilitates the breaking out of the tamper-evident element and the sealing element, this projection preferably likewise being essentially ring-shaped, but can also have any other geometric shape.
  • the can closure according to the invention is constructed similarly to the known can closure according to FIG DE 10 2013 003 154 B3 .
  • the can closure according to the invention thus has an inner closure part and an outer closure part, the outer closure part comprising a lower closure part and an upper closure part which can be pivoted to it.
  • a can lid is preferably attached to the upper closure part in order to be able to close the pouring opening so that the can can be closed again.
  • a pouring spout can be attached to the outer closure part.
  • the individual components e.g. outer closure part, inner closure part, upper closure part, lower closure part, closure cover, film hinges, etc.
  • the individual components are preferably made of plastic.
  • the problem with such a can closure is the fact that plastic is not absolutely gas-tight.
  • at least small amounts of oxygen can therefore enter the inside of the can through the can closure and oxidize the contents of the can, which reduces the shelf life. It is therefore desirable to minimize the disruptive ingress of oxygen through the can closure as much as possible.
  • the can closure therefore has in addition to the tamper-evident element and the pressure bulkhead an additional gas barrier, which is preferably much more gas-tight than the tamper-evident element and / or the pressure bulkhead. The additional gas barrier minimizes the ingress of oxygen through the can closure and thereby extends the shelf life of the closed can.
  • the gas barrier can consist of a gas-tight film, but other designs are also possible within the scope of the invention.
  • the gas barrier in the can closure according to the invention.
  • the gas barrier can be attached between the tamper-evident element and the pressure bulkhead, for example on the outside of the pressure bulkhead.
  • the gas barrier is attached to the inside of the pressure bulkhead.
  • the pressure bulkhead can be mounted in the can closure by means of a latching connection, preferably in the closure lower part of the closure outer part.
  • the outer closure part is connected to the inner closure part, for example by a welded connection or by an adhesive connection.
  • the invention not only claims protection for the above-described can closure according to the invention. Rather, the invention also claims protection for a can lid in which such a can closure according to the invention is already preassembled. Finally, the invention also claims protection for a can (e.g. Milk can, beverage can) with such a can lid with a preassembled can closure or with a can closure according to the invention.
  • a can e.g. Milk can, beverage can
  • FIG. 1 show a preferred embodiment of a can closure 1 according to the invention for a metal can, the can closure 1 according to the invention being particularly suitable for a can which is pasteurized or sterilized in the filled state before delivery.
  • the can is partially heated to over + 120 ° C, which leads to a correspondingly high internal can pressure which, with conventional can closures, can lead to an unwanted breakout of a tamper-evident element.
  • the can closure 1 is turned into a. Opening used in a metal can lid 2 of the beverage can.
  • the can closure 1 consists essentially of an inner closure part 3 and an outer closure part 4, both of which are made of plastic and are connected to one another in the assembled state by an adhesive connection or a welded connection.
  • the inner closure part 3 is located inside the can in the mounted state, while the outer closure part 4 is located outside the beverage can in the mounted state and rests on the can lid 2.
  • the outer closure part 4 in turn consists of a lower closure part 5 and an upper closure part 6, the The upper closure part 6 is attached pivotably to the lower closure part 5 by a film hinge 7.
  • the upper closure part 6 can therefore consist of an in Figure 1 Shown delivery position relative to the closure lower part 5 in a Figure 3 The position of use shown can be pivoted. In the delivery position according to Figure 1 the upper closure part 6 rests flat on the can lid 2. In the position of use according to Figure 3 however, if the upper part 6 of the closure is folded onto the lower part 5.
  • closure cover 8 which is attached to the upper closure part 6 in a pivotable manner by means of a film hinge 9.
  • the closure cover 8 can therefore consist of an in Figure 3 closed position shown in Figure 4 shown removal position are pivoted.
  • a pouring spout 11 is attached to the upper closure part 6 as a metering aid.
  • the pouring opening 10 is closed in the unopened original state by a tamper-evident element 12, the tamper-evident element being broken out of the pouring opening 10 when the upper closure part 6 is placed on the lower closure part 5 in the position of use according to FIG Figure 3 is folded.
  • the pouring opening 10 is closed in the original state by a pressure bulkhead 14, which has the task of keeping the pressure inside the can away from the tamper-evident element 12.
  • a pressure bulkhead 14 which has the task of keeping the pressure inside the can away from the tamper-evident element 12.
  • the pressure bulkhead 14 is constructed essentially in the form of a disk and has a sealing lip 15 on its peripheral edge which protrudes from the bottom 16 to the outside of the can, ie up how out Figure 7 can be seen.
  • the bottom 16 of the pressure bulkhead 14 is bulged towards the outside of the can, ie upwards.
  • This bulging of the bottom 16 of the pressure bulkhead 14 in turn leads to the sealing lip 15 on the pressure bulkhead 14 being bent radially outward with its free end in the direction of the arrow.
  • the contact pressure of the sealing lip 15 of the pressure bulkhead 14 on the associated sealing surface in the can closure 1 increases.
  • the sealing effect of the pressure bulkhead 14 thus increases with increasing can internal pressure p.
  • the pressure bulkhead 14 has an annular circumferential stiffening rib 17, depending on the design variant, the stiffening rib 17 in the position of use being able to lie under the likewise annular projection 13 on the underside of the upper part 6 of the closure.
  • FIG 8 shows that the pressure bulkhead 14 is mounted in the unopened delivery state of the can by a latching connection in the closure lower part 5.
  • the annular circumferential sealing lip 15 has at its free end a latching projection 18 which engages in a likewise annular circumferential latching receptacle 19 in the closure lower part 5.
  • the latching projection 18 and the latching receptacle 19 together form the latching connection which fixes the pressure bulkhead 14 in the closure lower part 5.
  • the latching projection 18 and the latching receptacle 19 also form a seal which seals the pouring opening 10.
  • the above-mentioned bulging of the bottom 16 of the pressure bulkhead 14 due to the can internal pressure p then leads the locking projection 18 and the locking receptacle 19, whereby a good sealing effect is achieved, which becomes even better with increasing can internal pressure p.
  • FIG. 8 It also shows Figure 8 that an additional gas barrier 20 is attached to the underside of the pressure bulkhead 14, which in this embodiment consists of a gas-tight film.
