う欠点があった。Traditionally, metal cans have been used for cans with G-su, beer, etc. sealed inside, but because these metal cans are easy to manufacture, can manufacturing factories are limited, and after the cans are made, they are emptied. The containers had to be transported to the factories where the cans were used and filled with the contents, creating a problem of inefficient transportation. In addition, since the metal cans 1 are hard and sturdy and do not burn, it is not easy to dispose of all the cans, which also poses a problem of can pollution. For this reason, in recent years, various types of plastics have been laminated to create plastic cylinders with properties suitable for cans such as self-standing, gas barrier properties, water resistance, oil resistance on the surface, and heat resistance on the surface. A can with a can body made of a laminated tube has been devised.Such a can is made by winding a plastic laminated film in a spiral shape to produce a long plastic tube or a tube with a layer of plastic on the inside. This tube is then cut to an appropriate length and used as a can body, and there are fewer problems such as empty can pollution as with metal cans. A metal lid is used for the lid.However, when a metal can lid is seamed with a sear to join a can body mainly made of plastic or resin, the can body is soft and slips easily. The drawback was that only the peripheral edge of the metal can lid was rolled up, making it impossible to securely connect it to the can body.

The purpose of the present invention is to provide a can that also has impact resistance, and consists of a can body formed of plastic or a laminated material with plastic laminated on the inner surface, and a metal can lid. The Kl' sign is that plastic is applied to the part that comes into contact with the can lid and that the plastic is heat welded to join the can lid to the can body.

れて、缶胴として使用される。The can body 1 is made of a laminated material with plastic, resin, or glass laminated on the inner surface, but in addition to its properties as a container, such as smoothness, oil resistance, water resistance, heat resistance, and ability to stand on its own. When used as a product container, the inner layer that comes into contact with food and beverages must be made of glass that does not pose a problem from a food hygiene perspective, or polyolefin ethylene/vinyl acetate such as polyethylene, polypropylene, or ethylene-clopylene copolymer. Copolymers, ionomers, etc. are suitable. Furthermore, in order to further impart gas barrier properties, it is also preferable to laminate aluminum foil, ethylene vinyl alcohol copolymer, vinylidene chloride, etc. In Fig. 1, two layers of various materials such as these are laminated to protect contents. This is a laminated film for 2 r
tx, 70μ from the inside? It is formed of a liglobilene layer A, a 7μ carboxylic acid graft holophylene layer B, a 9μ aluminum foil C, a 4.5 f/m2 urethane adhesive, and a 30μ polypropylene layer E. The edges of this laminated film 2 are overlapped and spirally wound to form a cylinder, and as a result, only the polypropylene layer A comes into contact with food, and the cylinder is free from food hygiene problems. It has become. A 200 μm adhesive sheet 3 of polyzolopylene is wound around the outer surface of the cylindrical body excluding the overlapping portion at the edge, and an approximately 600 μm adhesive plastic layer made of polypropylene and calcium carbonate kneaded in the same proportion is further wrapped around this outer surface. A coach ink layer 5 of 4 and 10 to 20 μm of polypropylene propylene and wolfberry copolymer is formed. In this way, plastic cylinders made of laminated materials mainly made of plastic or glasstic,
Then, it is cut to an appropriate length, for example, 5 to 30 on, 8 degrees, and used as a can body.

接合となる。Next, the can lid 10, which is placed on the upper and lower opening ends of the can body 1, is made of metal such as aluminum or steel coated with an anti-rust coating and is formed into a disc shape.
As shown in the figure, the top portion 11 and the peripheral portion 12 are formed concentrically. The peripheral edge portion 12 includes a rising portion 13 of a predetermined height that is continuous with the top portion 11, a flange portion 14 that expands outward from the rising portion 13 by a predetermined width, and a flange portion 14 that is folded downward from the flange portion 14. The folded bent portion 15 has a sharp shape, and when the opening end of the can body 1 is covered, the rising portion 13 fits into the inner wall of the can body 1, as shown in FIG. However, the flange portion 14 is adapted to come into contact with the bell and the first blood of the can body 1. Plastic 2 is applied to the parts of the metal can lid 10 that come into contact with the can body l, in this embodiment, the outer circumferential surface of the rising part 13 of the peripheral edge part 12 and the lower surface of the flange part 14.
0 is applied. This Silastic 20 is applied to the can lid 10 in advance in order to join the can body l and the can lid 10 by full bath bonding, and it can be used as a food or drink without causing any food hygienic finishing problems, and can also be used to bond the can body with the can body. A matte is used because it exhibits sufficient adhesion. Suitable materials for this purpose include modified polyolefins such as steam-modified polyglopylene or modified polyethylene, which are applied in a molten state and allowed to cool and solidify.Then, as shown in FIG. After the can lid 10 is fitted to the open end, the peripheral edge 12 of the can lid 10 is tightened using a metal can hammer as shown in Fig. 5. In this state, a high-frequency magnetic flux is applied to the peripheral edge of the metal lid. As a result, the metal lid generates heat, and this heat melts the applied Silastic and bath-bonds the can body 1 and the can lid 10, providing airtightness to the inside of the can.Metal lid. It is appropriate for the heat generation to melt the glass stick applied to the can lid, and further melt and weld some of the gelatin on the inner surface of the body, and excessive heat generation is not good. 1 is firmly and reliably joined by being compressed by the can lid 10 from both the inside and outside and by welding the plastic of the body in contact with the raised portion 13 of the lid and the flange 14.

た。Next, Table 1 shows the results of the internal pressure strength test of the glass composite can of the present invention compared with a conventional metal can. In this case, a laminated material having the structure shown in FIG. 1 was used as the can body, and the can body was formed to have a wall thickness of 1 mm and an inner diameter of 523 mm. Also, on the can lid, there is denatured porin 0 Robylene in the part that comes into contact with the can body. :
After it was applied and applied to the can body, it was tightened using a metal can tightening machine, and the rear frequency was used to seal it. On the other hand, the lids of conventional metal cans have a conduit or land formed thereon, which can be tightened using a metal can tightening machine and attached to the metal can body.

For example, the can body and can lid may be formed into a rectangular shape or a hexagonal shape as shown in FIG. You may also form an Eno oven lid. In addition, the gelaste paste to be applied may be applied only to the rising part or the flange of the can lid, as long as the can lid and the can body are reliably joined, and the welding can be done by heating, even if not by high-frequency magnetic flux. It's okay.
さらには、缶胴も図示の累月でなくとも他の素材を使用
することが可能である。Furthermore, the can body does not have to be made of the illustrated material, but may be made of other materials.
以上、説明したように、本発明によれば、プラスチ、り
又はグラスチックを内面に積層した積層材による缶胴と
金属製の缶蓋との接合が確実であり、これにより、缶詰
としての物性全治したプラスチック缶を提供することが
できる。As explained above, according to the present invention, the can body and the metal can lid can be reliably joined by the laminated material in which plastic, resin, or glass is laminated on the inner surface, thereby improving the physical properties of the can. We can provide fully cured plastic cans.
