Abstract
A blow-molded container is provided with an insert occluding its top opening. A closure structure at least partially encapsulates the insert article and includes a frangible web formed against the insert article. The container can be blow-molded in main mold halves and the closure structure, including the frangible web, can be formed by additional mold halves while the insert article is held in the container opening by an arm that is subsequently retracted or while the insert article is supported on a parison portion that defines the container body. In the latter instance a complete overcap for the insert article can be provided.
