Definitions

  • the invention relates to a can, in particular for receiving beverages with a substantially cylindrical shell, which is closed at its end faces by a respective cover plate, which is connected to the jacket, and with a closure element which is provided in a recess of a cover plate to reclosably open the can, the recess of the cover plate being surrounded by a first frusto-conical portion of the cover plate which tapers towards the interior of the can and which extends between a circular bending edge and a circular edge forming the boundary of the recess, and wherein the closure element has a substantially cylindrical holding portion which is inserted into the recess of the cover plate and which has a circumferential groove which receives the first frusto-conical portion of the cover plate and which is bounded to the outside of the can by a second projection on whichthe bending edge is supported.
  • closure elements that are ripped open by the user to create an opening in the can. These openings are usually not resealable.
  • closure elements are known which allow the opening and reclosing of a beverage can.
  • closure elements are complex to produce and prone to error in the industrial application and therefore problematic.
  • US 2,687,831 A shows a box with a closure element which can be snapped into a corresponding holder.
  • a closure element is suitable for the attachment of a spout, but can not absorb the necessary forces and moments that occur in a screw cap.
  • Other closures with insufficient strength are described in US 3,998,354 A and US 4,327,842 A.
  • Object of the present invention is to provide a can having a closure element that is resealable, which is simple and inexpensive to produce and that is easy to handle.
  • the closure element should neither affect the storage nor disposal of the can and be particularly robust. In particular, the forces and moments occurring during opening should be able to be safely absorbed.
  • a screw cap of the closure element is supported on the second projection in the closed state.
  • Essential to the invention is that the closure element can be easily and safely inserted into the recess of the cover plate. This results in a connection in the manner of a snap closure, which allows for a suitable choice of dimensions, a relatively easy insertion of the closure element into the recess, but there ensures a secure fit. At the same time compound is liquid-tight, so that an undesirable leakage of the contents of the can can be avoided.
  • a particularly high functionality in conjunction with a robust construction is achieved in that the screw cap of the closure element is supported in the closed state on the second projection. This ensures a safe end position when screwing.
  • the assembly of the can is facilitated in particular by the fact that the circumferential groove of the holding portion is limited in the axial direction by a first projection, which has a support shoulder towards the groove and is frusto-conical on the opposite side. In this way, the closure element slides easily over the edge of the recess during insertion into the exception, without causing plastic deformation.
  • a particularly secure seat of the closure element is made possible in that the circumferential groove of the holding portion has a width in the axial direction, which corresponds to the axial extent of the first frusto-conical portion of the cover plate. In this way, a game in the axial direction of the closure element is avoided.
  • the circumferential groove of the holding portion is limited to the outside of the can through a second projection on which the bending edge is supported.
  • a second frusto-conical portion is provided radially outside the first frusto-conical portion, which tapers towards the outside of the can. In this way, the spring action can be increased, so that even when using harder plastics for the closure element sufficient elasticity is given to allow a non-destructive sliding of the closure element.
  • the recess is arranged eccentrically in the cover plate and directly adjoins the edge of the cover plate. Moreover, this solution allows the consumer to empty the can without residue.
  • a particularly simple structure is achieved in that the closure element consists of an integrally formed base part and a screw cap.
  • a security seal provides the ability to detect whether the can is still original locked or has already been opened.
  • This functionality can be achieved by a rupturable safety cover.
  • the safety cover is a part of a plate whose edge forms the second projection on which the bending edge is supported.
  • a particularly high functionality in conjunction with a robust construction is achieved in that the screw cap of the closure element is supported in the closed state on the second projection. This ensures a safe end position when screwing.
  • the closure element is made of plastic, in particular a polyolefin, such as PE or PP.
  • a stackable can can be achieved in particular by virtue of the fact that the lower cover plate, which is opposite the cover plate with the closure element, has a recess which is designed to receive a closure element of another can on which the can is stacked.
  • can stacks are formed, in which the cans are supported on each other and secured against lateral slipping of the tipping, without exposing the closure elements inadmissible loads.
  • Fig. 1 shows a partial section through a box according to the invention
  • FIG. 2 shows a detail of FIG. 1.
  • the can of Fig. 1 consists of a cylindrical shell 1, which is closed at the top by a cover plate 2, which has a closure element 3.
  • the closure element 3 consists of a base part 4 and a screw cap 5, which can be screwed onto the base part 4.
  • the base part 4 consists of a plate 6, on which a downwardly projecting cylindrical extension 7 is integrally formed, which forms a holding portion. Outside the holding section 7, the plate 6 continues as a flange, the here - -
  • a first projection 9 is provided which is also annular.
  • a safety cover 10 is provided, which can be torn open via a tab 11. This ensures on the one hand before the first opening of the can additional security against leakage or contamination, on the other hand can be recognized by the user beyond doubt whether the can is still in its original state or has already been opened.
  • the edge region 12 of the cover plate 2, which surrounds the opening into which the closure element 3 is inserted, is composed of a first frusto-conical portion 13, which tapers towards the interior of the can and which extends between a circular bending edge 17 and a circular edge 20 extends, which forms the boundary of the recess.
  • the first frusto-conical section 13 is followed by a second frusto-conical section 14, which merges into a third frusto-conical section 15 at a further bending edge 19.
  • the circular edge 20 is supported under bias in a groove 21 of the holding portion 7, which extends between a first projection 9 and a second projection 8 of the downwardly projecting cylindrical extension 7 circumferentially. In this case, the circular edge 20 bears against a support shoulder 16 of the first projection 9.
  • the bias ensures a reliable sealing of the closure element 3 relative to the cover plate 2 of the can.
  • the bending edge 17 abuts on the underside 18 of the second projection 8, which is achieved in that the axial extent of the groove 21 and that of the first frusto-conical portion 13 are approximately equal.
  • the first projection 9 has on its lower side, which is opposite to the support shoulder 16, a beveled portion 22. This makes it possible to assemble the closure element 3 in a simple manner during production by snapping it into the recess of the cover plate 2. In this case, the first frusto-conical section 13 expands elastically to lock into the groove 21 after overcoming the first projection 9. Even during disposal, the closure element 3 can be separated from the rest of the can in a simple manner.
  • the present invention makes it possible to produce a robust resealable can by simple means, whereby a high utility value is achieved.
