Abstract: This liquid container and dispenser includes a rigid or semi-rigid housing 3, a charging and discharging opening defined by a mouth 3a of the housing for permitting the passage of liquid content into or out of the container, a flexible and open-ended bag 2 suspended from the housing opening, and valve structure 4, 5,5a, 6 for controlling the charging and discharging of the liquid content of the bag 2 via the opening. The bag 2 is made of an elastomeric material and is of sufficient wall strength to expand without rupture within the confines of the housing 3 from a relaxed contracted state 2a upon charging of the bag with liquid, and is returnable to its contracted state by its own inherent resilience in order to discharge its liquid content.

Abstract: An end cap for a container is generally dish shaped and is for fitting within a tubular container to be fixed in position at one end thereof or for sliding movement within the container as the container is emptied. The end cap includes a peripheral portion 129 which is capable of limited movement relative to the main portion of the end cap so as to allow movement of the end cap in one direction within the container but to cause locking of the end cap against the wall of the container when the end cap is caused to move in the opposite direction.
