Definitions

  • the present invention relates to a metal can lid with a resealable opening, in particular for beverage cans and for containers for storing food and other liquid, pasty, powdered and/or solid products.
  • the plastic closure part comprises a base part to be connected to the flanged edge of the can opening, in which base part an opening closed by a flat stopper is formed.
  • the flat stopper is connected to the edge of the opening via a plastic tear seam, so that the flat stopper connected to a tear-off tab can be detached from the plastic base part by exerting a pull on the tear-off tab and can be pivoted into an opening location.
  • the opening can be temporarily closed again by pressing in the flat stopper, which is preferably conical on its underside.
  • Resealable can lids are also, for example, in DE 10 2010 013 531 A1 , the DE 10 2015 112 428 A1 and the EP 2 354 022 B1 described.
  • U.S. 2018/016058 A1 discloses a resealable can lid having a collar portion and a lid receiving portion, each made of plastic and engageable with one another by a latching device, and a method according to the preamble of claim 1.
  • the DE 10 2006 020 696 A1 discloses a process for producing a coated thermoplastic material in which an adhesion promoter is added to a thermoplastic melt in the plastic state.
  • both the sealing frame with the fixed lid surface and the closing unit with the metal lid area that can be swung up are bonded using an adhesion promoter that is preferably suitable for food and/or has lubricating properties, in particular adhesive lacquer, in particular by a thermal process the adhesion promoter is added to the respective plastic material before the sealing frame and/or the closing unit is formed.
  • an adhesion promoter that is preferably suitable for food and/or has lubricating properties, in particular adhesive lacquer, in particular by a thermal process the adhesion promoter is added to the respective plastic material before the sealing frame and/or the closing unit is formed.
  • the adhesion promoter can be added to a plastic granulate that is used to produce a plastic injection molded part. A separate application of the adhesion promoter to the parts mentioned is not necessary, which means that the production costs can be reduced.
  • the can lid 1 shown in the figures consists of metal, in particular aluminum, and has a resealable opening.
  • a cover area 3 that can be swung up is provided in the cover in addition to a fixed cover surface 2 .
  • the flip-up lid portion 3 is separated from the fixed lid portion 2 by a circumferential micro-gap 4 or line of weakness (see in particular 6 ).
  • a sealing frame 5 made of plastic material enclosing the opening area is connected to the fixed cover surface 2, in particular by a so-called hot melt method using an adhesion promoter to ensure a firm connection with the aluminum of the cover.
  • a closing unit 6 is connected to the metal lid area 3 that can be swung up, which is also made of plastic and is pivotably attached to the fixed lid surface 2 via a pivot bearing 7 .
  • the swivel bearing 7 and the closing unit 6 are in turn connected to the fixed cover surface 2 or the cover area 3 that can be swung up, in particular via a hot melt connection using an adhesion promoter.
  • the closing unit On the side diametrically opposite the pivot bearing 7 , the closing unit is connected to a ripping member 8 that can be swung up and is arranged parallel to the top side 9 of the lid when it is not swung up.
  • the ripping member 8 is ring-shaped in a known manner and can be pivoted up about a pivot bearing 11 by engaging a finger in an engagement end 10 opposite the cover surface.
  • the sealing frame 5 and the closing unit 6 work together in a sealing manner via sealing and latching ribs 12, 13, 14 on the sealing frame 5 and associated receiving grooves 15, 16, 17 on the closing unit 6. As a result, at least three sealing edges 18, 19, 20 are formed, through which the opening area of the can lid is sealed. Even if a microgap 4 is used between the cover area 3 that can be swung up and the fixed cover area 2, the tightness of the can cover is thereby ensured.
  • the can lid 1 is provided with a micro gap 4. This is overlapped by the closing unit 6 , a first sealing area 26 being formed between the closing unit 6 and the cover area 3 that can be swung up and a second sealing area 27 between the closing unit 6 and the fixed cover area 2 .
  • the first sealing area is designed in such a way that the closing unit 6 is connected to the cover area 3 that can be swung up and cannot be torn open.
  • the second sealing area 27 is designed in such a way that it can be detached from the fixed lid area 2 when the can lid 1 is torn open with a predetermined maximum force.
  • the maximum force is preferably ⁇ 10 N, in particular ⁇ 5 N.
  • Both sealing areas 26, 27 are formed all the way around the opening portion of the can lid so that the inside of the can is completely sealed by these two sealing portions.
  • the sealing in the first sealing area 26 and in the second sealing area 27 is preferably carried out cohesively by a thermal process, in particular by a so-called hot melt process.
  • the shape of the sealing surfaces 26, 27 is as in 14 shown, preferably drop-shaped.
  • the Figures 8 to 10 show a further variant of a can lid according to the invention with a first sealing area 26 between the closing unit 6 and the lid section 3 that can be pivoted up and a second sealing area 27 between the closing unit 6 and the fixed lid section 2, which are each designed in accordance with the previous variant.
  • the difference from the previous variant is that instead of a micro-gap 4, here a weakening line 4' is provided between the fixed cover area 2 and the cover area 3 that can be swung up.
  • the weakening line 4' is designed as a sharp-edged notch.
  • the variant shown is also provided with a weakening line 4" between the fixed lid area 2 and the lid area 3 that can be pivoted up. Unlike the previous variant, this is designed as a deep-drawn deformation.
  • the weakening line 4" is also overlapped by the closing unit 6, with a first sealing area 26 between the closing unit 6 and the cover area 3 that can be swung up and a second sealing area 27 is provided between the closing unit 6 and the fixed cover area 2 .
  • the rest of the configuration is again the same as in the previously described variants.
  • a plastic part 28 is inserted into a slot 29 provided in the can lid 1 .
  • the microgap 4 adjoins the two narrow ends of the elongated hole 29 in each case.
  • the plastic part 28 is deformed in the shape of a mushroom in order to overlap the fixed cover area 2 on the one hand and the cover area 3 that can be swung up on the other hand on both sides. 15 shows the undeformed state.
  • the mushroom-shaped plastic part 28 is materially connected to the can lid 1, in particular by a thermal process using an adhesion promoter.
  • a weakening line 30 is also embossed into the plastic part 28 and is preferably produced during the sealing process of the can end 1 . This weakening line 30 allows the plastic part to be separated into two parts when the can lid is torn open. The opening forces are lower here than without the plastic part 28.
  • the inside of the can lid is laminated with a plastic film 25 which covers the entire inside of the lid.
  • the plastic film can also be ring-shaped and extend only a few tenths of a millimeter, in particular 3 to 4 tenths of a millimeter, beyond the microgap 4 or the weakening line on both sides.
  • Another possibility is to use a disk-shaped sealing film that extends radially outwards beyond the microgap 4 or the weakening line by a few tenths of a millimeter, for example 3 to 4 tenths of a millimeter.
  • the sealing foil can be designed as a largely flat disk. Both the ring-shaped and the disc-shaped sealing foil are preferably designed as a stamped part.
  • the inside of the end can deviate from the exemplary embodiment also be at least largely free of laminations and the like.
  • the inside of the lid can be provided with a lacquer layer, in particular one suitable for use with food, in order to prevent the goods in the can from coming into contact with the metal lid material.
