摘要：
A plastic part is molded onto a top of a container having folded flaps on the top of the container. The container is formed into a tube shape from a flexible web material with crease lines. Contents are filled into the tube of web material, the tube is transverse sealed and a primary shape container is obtained by cuffing the web material along crease lines. A final shape container is obtained with multi-folding of folded flaps onto the container top. A mold of an injection molding apparatus is applied against the top of the container, and fusion thermoplastic material is injected into the cavity formed between the mold and the top of the container. The thermoplastic material is then cooled, and the mold removed to leave the plastic part molded to the top of the container.
