Embodiment Construction

[0030]The present invention one-piece, blow molded container 10 with one or more rigid, thick-walled, fitment 12 and a thin-walled, flexible, film bag portion 14 as depicted in FIGS. 1-6, 9-10 is blow molded from a continuous source of fluoropolymer material, using a single blow molding process, to form the fully integrated, one-piece blow molded container 10 in the absence of any post-molded welds, seams, seals or other mechanical engagement means. The thin-walled, flexible, film bag portion 14 further includes a continuous wall 16 and a bottom portion 18. The bottom portion 18 can selectively be either flat as shown in FIGS. 1 and 4, or can be round as depicted in FIGS. 5 and 6.

[0031]The one or more fitment 12 of the present invention 10, further includes a neck 20 and an orifice 22. The orifice 22 has an outer diameter surface 24 and an inner diameter surface 26. The fitment 12 is blow molded simultaneously with the bag portion 14 as a single piece and the neck 20 is compression ...

Abstract

A one-piece, blow molded fluoropolymer container, having a thin-walled, flexible bag portion and one or more rigid, thick-walled fitment, wherein the bag and the one or more rigid fitment are formed during the same blow molding process, from a continuous source of fluoropolymer material, to form a complete, one-piece, fully integrated container.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Patent Application No. 60 / 931,958 entitled ā€œONE-PIECE BLOW-MOLDED CONTAINER WITH RIGID FITMENTā€ and filed on May 29, 2007 for Cathy G. Edgington, which is incorporated herein by reference.FIELD OF THE INVENTION[0002]A one-piece, continuously blow molded, fluoropolymer container for storage, transport, and dispensing of various liquid, gel, powder, and pelletized materials. In particular, the present blow molded container invention is formed using a continuous, single step blow molding process to create a complete, fully-integrated, one-piece container that includes a collapsible, thin-walled, bag portion constructed of a thin layer fluoropolymer film and one or more rigid fitment which are formed of a greater thickness fluoropolymer resin, as compared to the thin fluoropolymer film.BACKGROUND OF THE INVENTION[0003]The assembly of multiple component (multi-piece) containers constructed...
