ムシールの分離という欠点があった。3-1-2. Conventional technology In the case of thermoplastic synthetic resins, it is technically difficult to bond and mold them with dissimilar materials such as metal and wood. That is,
When dissimilar materials are set in an injection mold and molded simultaneously, the joint surfaces may peel or moisture or gas may enter from the end of the joint, resulting in the synthetic resin material not being completely attached to the dissimilar materials. It was impossible to be in close contact with each other. Therefore, in the past, methods have been used in which the joint is formed using an adhesive or a rubber seal is wrapped around the end portion. However, when adhesive is used, there is a problem that the durability of the product decreases due to the deterioration of the adhesive, and the method of wrapping a rubber seal around the end part has the disadvantage of increasing the number of work steps and labor, and separating the rubber seal. was there.

A non-synthetic resin plate with one side covered with a synthetic resin material and its peripheral edge protruding outward is molded into the desired vessel shape, and after the vessel body is placed in a mold, it is covered with a synthetic resin material. The synthetic resin liquid is injected onto the other side of the container body which is not covered, and the peripheral edge of the container body is rolled up and covered, and the tip portion is bonded and fixed to the synthetic resin material portion of the one side surface. This is a molding method using synthetic resin materials.

大である。3-31 Effects of the Invention Since the present invention is a molding method that involves the above-mentioned one step, there is no need for a secondary processing step, and the entire surface of the container body to be molded from a non-synthetic resin material can be reliably and reliably made of a plastic synthetic resin material. It will be possible to quickly surround and cover the
Manufacturing costs are extremely low, the external color of the molding body can be reliably changed between the outside and the inside, and the synthetic resin material can play a role in supplementing the strength of the molding body. For example, weak aluminum foil, which is used as a component for electromagnetic shielding, has a conductive effect, but it is now possible to reinforce it with synthetic resin material, and it is now possible to reduce material costs. The finished product retains sufficient durability against peeling and corrosion caused by external stimuli, and its effects are significant.
