Abstract
PURPOSE:To obtain a fitting method by which a seal piece can be easily stripped off and the opening edge is made smooth, by insert-molding a mouth piece within a mold, having a periphery as a molding face at the opening edge of the mouth piece and also having the seal piece within the mold, which has a higher melting point than a synthetic resin forming the mouth piece of a container and has no compatibility. CONSTITUTION:A mouth piece 1 set at the top of a drum body 6 of a compact container is molded by extrusion inside a mold 4 with a seal piece 3 and then an opening 2 thereof is sealed by the seal piece 3. Accordingly resin flows in naturally also on the periphery of the seal piece 3 forming a mold 4 surface at the opening edge 5 of the opening 2. Since said seal piece 3 has a higher melting point than the synthetic resin flowed inside and has no compatibility with the resin, the seal piece does neither solve nor adhere to the synthetic resin. Therefore, the seal piece 3 fits very closely with the faces of the resin.
