Definitions

  • the invention relates to an easy-to-open can lid according to the preamble of claim 1.
  • Such an easy-to-open can lid is known from DE 196 20 448 A1.
  • easy-to-open can lids in which the Closure part was formed by an aluminum foil, is at the beginning mentioned, easy to open can lid in the manufacture of the lid ring resulting sheet metal part used as a closure part.
  • the Sheet metal blank or the sheet metal from which sheet metal blank is punched out at least has a heat sealable coating on one side.
  • This coating can e.g. a film made of polypropylene or polyethylene terephthalate, or also a sealable, organic paint. This coating is in the beginning of the production of the cover Inside of the sheet metal blank or the later cover, i.e.
  • the stamped sheet metal part is heat-sealable Coating is arranged on the later inside of the lid Heat sealing two heat sealable coatings on top of each other, which makes a pressure tight Sealing guaranteed.
  • the closure part is sealed with a Opening tab or an opening ring so that you can pull on the Pull off the opening tab of the closure part from the ring flange of the cover ring and so that the can can be opened easily without a can opener.
  • the invention is based on the object of an easy-to-open can lid to improve the type mentioned in the introduction that the can after Pulling off the closure part can be closed again in a simple manner.
  • the can lid combines two essentials Characteristics.
  • the closure part By peeling off the closure part using the opening flap the closure part can be easily removed from the cover ring and the can opened become. If the contents of the can are only partially used, the closure can be closed place on the lid ring so that the shape points towards the inside of the can. By pressing the shape into the lid opening, the peripheral portion in the lid opening clamped and thus the closure part firmly on the lid ring held.
  • the coating on the flange also ensures a adequate sealing.
  • the finished, easy-to-open can lid is in one in the drawing Partial section shown, this partial section the edge region of the can lid 1 shows.
  • This can lid 1 consists of a lid ring 2 and a closure part 3.
  • the closure part 3 is formed by a sheet metal part, which in the manufacture of the Cover ring 2 occurs.
  • Both the cover ring 2 and the closure part 3, both are made from the same sheet metal blank, have on the inside - this is with of the finished can facing the can body 4 in the drawings below lying side of the can lid 1 - a heat sealable coating.
  • Coating which is not shown in the drawing, can be a laminated film, or a directly extruded polypropylene layer, Trade polyethylene terephthalate, a sealable lacquer or the like.
  • the cover ring 2 has on its inner edge formed by a flattened curl Ring flange 5 on.
  • a flattened curl Ring flange 5 By rolling the ring flange 5, which in DE 196 20th 448 A1 is described in more detail, the ring flange is on its entire outside, i.e. on its outward-facing upper side 5a and its inward-facing can Bottom 5b, provided with the heat sealable coating.
  • the closure part 3 On the ring flange 5 is the closure part 3, which is punched out by one of the cover ring 2 surrounded sheet metal part according to that in the aforementioned document described method has arisen, sealed with its edge area 3a.
  • the cover ring 2 also has an outer flange 6, which together with a corresponding outer flange 7 of the can body 4 to form a double fold serves.
  • a sheet is used to produce the can lid 1, e.g. Tinplate, chrome-plated sheet metal or aluminum sheet with a thickness between 0.05 and 0.3 mm. This sheet has at least on one side, which the finished can As previously mentioned, the interior of the can faces a heat-sealable coating. The sheet can be painted on the opposite outside.
  • the can lid is manufactured from the sheet metal blank in several Forming steps that are described in DE 196 20 448 A1. In addition these forming steps are used in the manufacture of the invention Can lid the sheet metal part, which neither forms the closure part 3, before Punch out of the cover ring 2 with one from the plane E-E of the sheet metal part outstanding, pot-like expression 3b, 3c provided what by hollow embossing, or multi-stage deep drawing can be done.
  • the pot-like shape 3b, 3c has cover field 3c extending essentially parallel to plane E-E and one circumferential section 3b extending substantially perpendicular to the plane E-E.
  • the Circumferential section 3b is in its outline shape and in its outline dimensions Outline shape and the outline dimensions of the lid opening 9 adapted so that the Closure part 3 with its characteristics, i.e. its peripheral portion 3b, jamming in the lid opening 9 can be used, as shown in FIG. 2.
  • Fig. 1 shows the can lid 1 in the sealed state, i.e. the closure part 3 is with sealed its flat edge region 3a with the flattened ring flange 5.
  • the expression 3b, 3c is expediently made so that it is opposite the Can is directed outwards. This makes it easier to pull off the Closure part 3 for opening the can.
  • an opening tab 11 or an opening ring is provided, which can be gripped with the fingers Initiation of pull-out forces allowed.
  • the opening tab 11 has one Fastening tab 12, which is bent along a bending edge 12a.
  • This Fastening tab 12 is bent over and be along a bending edge 12a bent free section is with the outside of the edge region 3a of the Closure part 3 connected by heat sealing, gluing or the like. The connection takes place in such a way that the bending edge 12a in the vicinity of the outer edge of the Closure part 3 is arranged.
