DESCRIPTION:
BRIEF SUMMARY
Technical Field
This invention relates to a container with a metallic top or cover comprising a container body provided with a flanged portion made of a plastic material and a metallic cover roll-seamed around the container body and also relates to a method of manufacturing the same.
Background Art
Metallic containers, for example, metallic cans have various shapes and can be classified into three-piece cans and two piece cans. The three-piece can is called a tinplate-soldered can which has a structure in which a cylindrical can body, a top or cover, and an end are double seamed and sealed. The two-piece can is called a tinplate-pressed can which has a structure in which a can body and an end portion (container body) are formed integrally and a cover is double seamed around the rim of the integral container body to seal the same.
These metallic cans are used as food packaging containers for packaging various foods, juices, soft drinks, dry foods and the like and are thus rigid containers of particular excellence in sealing and preservation properties. However, metallic cans have the following points to be improved. of the metallic can; under an impact and the can is deformed; comparison with a plastic container; freely changed in case the container is made of a metallic material and the display is only carried out by a printing operation; and which can be verified without opening the container.
For solving these problems or drawbacks of the conventional metallic cans described hereinabove, a container with a metallic cover in which a metallic cover is secured to a plastic container body is conceivable.
It is however difficult to secure a metallic top or cover to a plastic container body simply and air-tightly.
Disclosure of Invention
A first object of this invention is to provide a container provided with a metallic cover and comprising a plastic container body and a metallic cover which can be manufactured simply and air-tightly.
A second object of this invention is to provide a method of manufacturing a container with a metallic cover in which the metallic cover can be secured to the plastic container body with good air-tightness.
A third object of this invention is to provide a method of manufacturing a container with -a metallic cover having ample buckling strength and heat resistance to withstand the force applied when the metallic cover is roll-seamed around the plastic container body.
The fourth object of this invention is to provide a method of manufacturing a container with a metallic cover which is capable of ensuring positive securing of the metallic cover to the plastic container body, and which is suitable for mass production.
A fifth object of this invention is to provide a method of manufacturing a container with a metallic cover by which the plastic container body can be formed into a true spherical shape.
A sixth object of this invention is to provide an apparatus for manufacturing a container with a metallic cover capable of easily manufacturing a plastic container body suitable for being easily roll-seamed with the metallic cover. metallic cover comprising a container body 14 provided with a plastic flanged portion 15 and a metallic cover 11 having a peripheral edge portion 12 which is to be roll-seamed around and with the flanged portion 15. a container with a metallic cover comprising the steps of applying a coating of a heat-sealing compound 13 prepared from more than one of a denatured polyolefin, an ionomer resin, and an ethylene-acrylic acid copolymer on the inner surface of the peripheral edge portion 12 of the metallic cover, roll-seaming the metallic cover 11 around a flanged portion 15 of a container body 14, and fusing the flanged portion 15 and the peripheral edge portion 12 of the metallic cover 11 by a heating method utilizing high frequencies, ultrasonic waves, electric heating power or steam to secure these members to each other. a container with a metallic cover characterized by thermal formation in which a container body is thermally formed by using a sheet blank
