ABSTRACT:
A collapsible container (10) comprises a collapsible housing (12) having a nozzle (14) at a nozzle end (16), a base (18) at an opposite base end (20), and a collapsible sidewall (22) interconnecting the nozzle and the base. The collapsible housing defines interconnecting elements (44) for coupling the base to the sidewall for allowing the base to evert and invert, the base having a shape and size substantially corresponding to that of a collapsed interior space (26) of the collapsible container when it is collapsed. The interconnecting elements are positioned approximately at a minimum non-expanded laterally-outward position (32) of the sidewall, and the wall (34) of the base element at the interconnection elements extends almost parallel to an axis of elongation of the collapsible container. The base includes an inwardly-directed protrusion (38) thereon having dimensions corresponding to a nozzle interior space (28) and being positioned to be inserted into the nozzle from the interior of the container when the container is fully collapsed. A one-way valve nozzle device (64) can be positioned at the nozzle.
