ABSTRACT:
A collapsible dispenser includes a main storage tank for storing material contents, a hook structure for catching a used-up portion of a collapsible side wall of the main storage tank to be kept folded, a top cap attached to the main storage tank for outputting the material contents from the main storage tank, and a bottom plug. The main storage tank includes a tank base and a collapsible side wall. The hook structure extends from the inside shoulder of the top cap and includes a keeper wall extended from the inside shoulder, a thickened lower edge formed at a lower edge of the keeper wall, and a hook formed at the end of the edge. A bottom plug is attached to the tank base of the main storage tank for refilling the material contents inside the main storage tank. The collapsible side wall includes a plurality of bellows folds. Each of the folds has a circumferential protruded lip which conforms to and cooperates with the hook for preventing sliding of a folded portion of the collapsible side wall. The keeper wall includes openings for allowing any residual contents left in a folded portion of the collapsible side wall to be squeezed into the main storage tank.
