CONTAINER WITH REMOVABLE LINER, FITMENT, AND ADAPTER

摘要

A lined container includes a rigid-walled vessel having a discharge port, a flexible liner having a discharge fitment, and an adapter for connecting the discharge fitment to the discharge port of the vessel. The adapter includes a tubular member having a coaxial bore and a set of male, tapered threads for engaging with female, tapered threads of the discharge fitment of the flexible liner. The adapter also includes a flange member for accommodating a sealing ring abutted against an inner wall of the rigid walled vessel. A method of inserting the liner and adapter into the rigid vessel includes guiding the adapter (with liner attached), using a guide leash, through a top aperture, into the vessel, and then out the vessel through the discharge port (leaving just the liner inside).
