초록 ▼

A method for blow-molding a thermoplastic container having a body-portion and a neck-portion provided with a dispensing orifice and internal attachment means, with such method including the steps of: (a) forming a hollow parison of thermoplastic material having an open end; (b) placing the parison within a female mold cavity having a body-forming portion and a neck-forming portion such that the open end of the parison is located within the neck-forming portion of the mold cavity; (c) inserting an expandable core pin into the open end of the parison, with such core pin including blowing means connected to a pressure source and having relieved areas formed on its exterior surfaces; (d) expanding the core pin such that the open upper end of the parison is forced against the neck-forming portion of the mold cavity and into the relieved areas on the exterior of the core pin, thereby forming the internal attachment means on the inner surface of the open end of the parison; (e) introducing pressure through the blowing means of the core pin to the interior of the parison thereby expanding the parison against the inner surfaces of the body-forming portion of the female mold cavity to form the body-portion of the thermoplastic container; (f) removing the molded thermoplastic container from the female and mold cavity; and (g) collapsing the expandable core pin and, thereafter, removing the core pin from the neck-portion of the thermoplastic container.

A method of blow-molding a thermoplastic container having a body-portion and a neck-portion provided with a dispensing orifice and internal attachment means, said method comprising the following steps: (a) forming a hollow parison of thermoplastic material having an open end; (b) placing said parison within a female mold cavity having a body-forming portion and a neck-forming portion such that the open end of said parison is located within said neck-forming portion of said mold cavity; (c) inserting an expandable core pin into the open end of said parison, said core pin having relieved areas formed on its exterior surfaces and including blowing means connected to a pressure source; (d) introducing means within said corepin and thereby expanding said core pin such that said open end of said parison is forced against the neck-forming portion of said mold cavity and into the relieved areas on the exterior of said core pin, thereby forming said internal attachment means on the inner surface of the open end of said parison, and such that a seal is created by said parison between said corepin and said neck-forming portion of said mold cavity and the entire upper end of said mold cavity is effectively sealed other than said blowing means; (e) introducing pressure through said blowing means of said core pin to the interior of said parison thereby expanding said parison against the inner surfaces of said body-forming portion of said female mold cavity to form the body-portion of said thermoplastic container; (f) removing said molded thermoplastic container from said female mold cavity; and (g) collapsing said expandable core pin and, thereafter, removing said core pin from the neck portion of said thermoplastic container.
