Description

[Detailed Description of the Invention] "Industrial application field" The present invention relates to a water receiver provided with a drainage port when a container body is integrally formed with a water receiving sheet by insert molding.

"Prior art" This type of insert-molded product has a water-receiving sheet that is a vacuum-formed (sheet-formed) product and a drainage port that is an injection-molded product that are separately inserted into a foam mold, and then foam-molded. The foamed molded product was taken out, and the water receiving sheet and the drainage port were joined with an adhesive to prevent water leakage.

"Problems to be solved by the invention" In the conventional technology, since the water receiving sheet and the drainage port are separate bodies, it is necessary to perform water leakage treatment after insert molding,
Moreover, although this processing work is time-consuming, it is difficult to form a perfect seal, which is a bottleneck in molding. Therefore, if it is an injection molded product in which the water receiving sheet and the discharge port are integrated, it is not necessary to perform water leak treatment, but the injection molded product is
There are inconveniences such as a long molding time and an increase in cost as compared with molding separately.

"Means for Solving Problems" However, according to the present invention, the drain port is joined to the opening of the water receiving sheet by heat fusion before the insert molding.

[Operation] Therefore, according to the present invention, the water leakage treatment after the insert molding is made unnecessary and the water leakage from the joint between the water receiving sheet and the drain port is prevented without increasing the molding time and the cost. It can be easily and surely prevented.
