Definitions
- the invention relates to a method for producing a with a can body connectable, limiting a removal opening and a heat sealable Coating lid ring on which to form a Can lid a closure membrane covering the removal opening hot-sealable, in which method a sheet metal strip with parallel Side edges is formed into a tube and the side edges parallel to Pipe longitudinal axis are welded or glued, the pipe manufactured in this way pipe sections of equal length with parallel planes Cut edges is divided and the pipe sections are formed into cover rings be, with a first cut edge to an outer flange for connection molded with a can body and the second cut edge is rolled up.
- the invention has for its object a method of the aforementioned Kind of training in such a way that optimal corrosion protection is achieved can.
- the second cutting edge leads to the achievement of the object according to the invention away from the side intended for the heat-sealable coating rolled up and the heat-sealable coating onto the molded lid ring is applied.
- Suitable metals for carrying out the method according to the invention are all metals known for the manufacture of cans or cover rings, such as aluminum, Steel or tinplate.
- the parallel side edges of the sheet metal strip are preferably one Butt joint pressed together and by means of a laser beam welded to the pipe.
- the heat-sealable coating can be carried out in a known manner in a solvent sprayed loosely on the cover ring or by a powder coating in powder form, e.g. as polypropylene powder, applied to the cover ring become.
- the cover ring is turned away from the heat sealable coating Side coated with a heat-resistant varnish.
- the heat-resistant paint is sprayed onto the cover ring.
- the tubes can be pre-cut from sheet metal strips Formats produced and regardless of it in the individual pipe sections be divided.
- the method according to the invention is particularly well suited for continuous Manufacture of cover rings.
- the sheet metal strip is in the form of rolled goods as a coil and is continuously formed into a tube by roll forming.
- the pipe sections are continuously produced at a rate of per unit time Pipe length corresponding clock rate separated from the pipe.
- FIGS. 1 and 2 In the case of a method shown in FIGS. 1 and 2, one is rolled up to a coil 10 wound tape in the form of a sheet metal strip 12 parallel side edges 14, 16 unwound from the coil 10 and in the tape running direction x continuously formed into a tube by roll forming.
- the parallel side edges 14, 16 of the metal strip 12 pressed together to form a butt joint and by means of a laser beam 18 to form one another a longitudinal weld 21 welded to the tube 20.
- the cover ring 30 has a conventional outer flange 32, the free End of a first cutting edge 26 of the cylindrical ring 24 corresponds.
- the Outer flange 32 merges into a horizontal ring surface 34.
- the inner edge 36 of the annular surface 34 delimiting a removal opening 38 is to be eliminated a risk of injury and to increase the rigidity of the cover ring 30 with a radially outward edge, which is the second cutting edge 28 corresponds to the cylindrical ring 24, rolled up.
- the curling up of the inner edge 36 of the horizontal ring surface 34 is such that the second Cutting edge 28 of the cylindrical ring 24 on the later against the inside of the can facing side comes to rest.
- the cover ring 30 is on its later Outside with a heat sealable coating 40 and on the later side facing the inside of the can with a heat-resistant lacquer layer 42 provided.
- a heat-resistant lacquer layer 42 provided on the inside of the outer flange 32 .
- Sealant 48 applied on the inside of the outer flange 32 . The drying of the sprayed-on layers 40, 42 and sealant 48 is typically carried out in an oven.
- the cover ring 30 is provided with a closure membrane 44.
- the Sealing membrane 44 which also has a heat-sealable coating, e.g. Polypropylene, is against the heat sealable coating 40 des Cover ring 30 sealed and thus forms an easy-open can lid 50.
- the closure membrane 44 can be provided with a tear-open tab 46 his. In this case, the seal between the sealing membrane 44 and the annular surface 34 so that the sealing membrane of the Ring surface or from the edge of the seal can be removed by peeling can.
- the sealing membrane is 44 inseparably connected to the cover ring 30. In this case the membrane pierced to the opening and along the inner edge of the annular surface 34 removed from the cover ring 30.
- the provided with the sealing membrane 44 cover ring 30 is after Filling a filling material as a can lid 50 crimped onto a can body.
- the filling material can also be placed in a previously with a cover ring 30 provided can body are filled. In this case it will be the last Step, the sealing membrane 44 is sealed onto the cover ring 30.
