Definitions

  • the invention relates to a can lid, in particular for beverage cans, with a metallic lid surface in which an opening delimited by a closed edge of the lid surface is formed, which is closed by a closure piece of the metal lid surface, the closure piece being formed at least in sections along the edge the microgap extending from the lid surface is separated from the surrounding lid surface, an edge of the closure piece and the edge of the surrounding lid surface adjoining the microgap, and wherein the closure piece is movable out of the plane defined by the opening to uncover the opening, and having a layer of a Plastic material that is applied to a flat side of the metallic cover surface, covering the microgap.
  • Can ends of this type are used extensively in the manufacture of beverage cans, food cans and the like. They are easy and inexpensive to manufacture, enable space-saving stacking of similar cans and can be easily opened and, if necessary, closed again by manually moving the closure piece. Due to the micro-gap, when the can is opened there are no harmful metal particles entering the interior of the can. The tightness of the can lid is ensured by the layer covering the microgap, despite the lack of a continuous metallic connection between the closure piece and the surrounding lid surface.
  • the layer of plastic material tears in the area of the microgap, so that the opening is subsequently free.
  • the opening process could result in stretching of the layer and undefined unraveling of the same, for example in the formation of fringes. This is undesirable, particularly because it increases the amount of force required to open the can and may prevent the contents of the can from escaping through the opening.
  • the visual appearance of the opening is adversely affected.
  • the task is solved by a can lid with the features of claim 1 .
  • the invention provides that the edge of the closure piece and the edge of the surrounding lid surface are offset from one another transversely to the plane defined by the opening.
  • one of the adjoining edges protrudes from the other and, when the edges move apart as a result of the opening process, forms a cutting edge which moves through the layer and ensures reliable and defined severing of the layer.
  • the layer is thus sheared rather than cracked.
  • the layer of plastic material can be a foil or a foil-like layer which is connected to the metallic cover surface, for example adhesively.
  • a foil made of plastic material can be connected to the metallic cover surface by means of lamination.
  • the layer can also be a foil laminated onto the metallic cover surface. In principle, the layer could also be produced by applying a liquid plastic material and then curing it.
  • the micro-gap can be a stamping gap, in which case the adjoining edges can touch at least in certain areas.
  • the plane defined by the opening can coincide with the surface extension of the lid surface or the closure piece.
  • a step with an angular or angular cross-section can be formed in the cover surface.
  • Such a step develops a particularly pronounced notch effect, which supports the severing of the plastic coating.
  • the edge of the closure piece and the edge of the surrounding cover surface can also be offset in height from one another by at least 10% and at most 90%, preferably at least 25% and at most 70%, of the thickness of the metal cover surface. With such a height offset, a clear cutting edge is formed on the one hand and, on the other hand, a sufficient overlapping of the edges in the closed state of the can is ensured with common thicknesses of the lid surface.
  • the edge of the closure piece is preferably offset in the opening direction relative to the edge of the surrounding lid surface. This ensures that the cutting effect starts immediately when the can is opened and not just before a certain distance can be bridged without a cutting effect. If the layer is applied to the rear flat side of the cover surface in relation to the opening direction, the rearwardly protruding edge of the surrounding cover surface acts as a cutting edge. If, on the other hand, the layer is applied to the front flat side of the cover surface in relation to the opening direction, the edge of the closure piece that protrudes forward acts as a cutting edge.
  • microgap has a maximum width of 0.02 mm and/or that the closure piece is held in the surrounding cover surface by clamping. This has proven to be particularly favorable in practice.
  • the layer is preferably applied to an inside of the metallic cover surface.
  • the layer is therefore preferably located on the lid side facing towards the inside of the can. Generally, this is the underside of the metallic lid surface.
  • the layer can be applied to the flat side of the metallic cover surface over the entire surface. This is advantageous in terms of manufacturing technology and ensures a particularly high sealing effect.
  • the layer can be in the form of a film and/or can be applied to the metallic cover surface in a firmly adhering manner, for example by sealing.
  • the plastic material can be food grade polypropylene.
  • the layer has a weakening, in particular a notch or at least a partial notch, which is arranged at a distance from the microgap.
  • the weakening reduces the force required to open the can. Due to the distance between the weakening and the microgap, a high tightness is ensured - even in the case that the weakening is considered partial or complete end notch is executed.
  • a partial or complete notch in particular, it is advantageous if the composite of the metal and the plastic material is of particularly high quality without any defects worth mentioning.
  • a handle, pull and/or lever element for lifting or swinging open the closure piece is attached to the closure piece.
  • a user can actuate the handle, pull and/or lever element in order to press in, lift off or swivel open the locking piece.
  • a two-armed lever element made of a plastic material can be provided, which is firmly connected to the metallic cover surface.
  • the handle, pull and/or lever element preferably has an annular handle section such as, for example, an annular strap.
  • a ring tab is particularly advantageous because it can be grasped easily and the respective can can be opened by means of a conveniently executable pulling movement.
  • a special embodiment of the invention provides that a sealing frame made of plastic material enclosing the opening is connected to the surrounding cover surface and a closing unit made of plastic material carrying the closure piece is pivotably attached to the surrounding cover surface, the sealing frame and the closing unit having sealing and locking ribs and associated receiving grooves can be releasably connected to one another in a fluid-tight manner.
  • a can end has a reclosable opening.
  • the sealing and locking ribs and the receiving grooves are preferably designed in such a way that complete reclosing by the snap-locking connection can be felt and possibly acoustically.
  • the invention also relates to a method for producing a can end, in particular a can end for beverage cans, preferably a can end as described above, wherein an at least partially flat full metal element is provided, a closure piece is stamped out of the metal element and reinserted into the opening formed by the stamping process, and wherein a layer of a plastic material is applied to a flat side of the metal element such that the parting line between the stamped out closure piece and the opening of of the layer is covered.
  • a predetermined height offset is produced between an edge of the closure piece and an adjacent edge of the opening in a direction pointing transversely to the plane defined by the opening.
  • one of the adjoining edges forms a cutting edge, which moves through the layer when the can is opened and ensures a reliable and defined separation of the layer via a notch effect.
  • misalignment of the adjoining edges also occurs during stamping because the closure piece is first forced out of the metal member.
  • this is a temporary transient condition that inevitably occurs due to the stamping process.
  • the invention provides for a targeted positioning of the adjoining edges in order to create a vertical offset that lasts until the can is opened for the first time.
  • the closure piece is preferably incompletely moved back into the opening. This is advantageous in terms of process technology.
  • the height offset is set and/or fixed in a calibration unit after the incomplete movement back. By appropriate calibration, the relevant edges can be positioned relative to one another with great precision.
  • the application of the layer to the flat side of the metal element is preferably carried out after the height offset has been produced while maintaining it. This rules out damage to the layer by the device used to generate the height offset.

  • an adhesive lacquer layer (not visible in the figures) can be provided.
  • the layer 33 is applied to the inner flat side 30 of the metallic cover surface 13 over the entire surface. In certain applications it could also be sufficient to provide a layer 33 only in the vicinity of the microgap 21 .
