Abstract
An insert-molded container in which a secondary container made of transparent synthetic resin is integrally provided to the outside of a primary container, the secondary container includes a gate mark, and a vapor-deposited layer is provided on the outer surface of the primary container in a peripheral area of the gate mark is manufactured by a manufacturing method of insert-molded container. The method includes: a cover attaching step of attaching a cover member made of transparent synthetic resin to the outer surface of a part of the primary container where a vapor-deposited layer is provided; a placing step of placing the primary container in a mold with the cover member facing a gate; and an insert molding step of injecting a transparent synthetic resin material from the gate.
Claims8
A manufacturing method of an insert-molded container having a double-wall structure in which a secondary container that is made of transparent synthetic resin and covers an outer surface of a primary container is integrally provided to an outside of the primary container, the method comprising:
- a cover attaching step of attaching a cover member to an outer surface of a part provided with a vapor-deposited layer of the primary container provided with the vapor-deposited layer on an outer surface, the cover member covering a part of the vapor-deposited layer and made of transparent synthetic resin;
- a placing step of placing the primary container in a mold with the cover member facing a gate;
- and
- an insert molding step of integrally forming the secondary container to an outside of the primary container by injecting a transparent synthetic resin material from the gate into the mold, wherein:
- the cover member is formed into a shape that includes a cover main body and a shaft portion protruding from a center of the cover main body, and
- in the cover attaching step, the shaft portion of the cover member is inserted from outside into a through hole of the primary container to attach the cover member to the primary container.
