Abstract
Abstract A device for dispensing a liquid from a collapsible container comprises a pair of elastic plates hingedly mounted to each other along one edge permitting them to be pivoted to an open position or to a closed position, and a sleeve of flexible material secured to the pair of elastic plates along their hinged edges for receiving a liquid-filled collapsible container. Each of the elastic plates is pre-formed with a curve which is convex from the side facing the flexible sleeve. The arrangement is such that when the liquid-filled collapsible container is received within the flexible sleeve and the two curved elastic plates are pivoted to their closed positions, they apply, due to their elasticity, a continuous force to the collapsible container for dispensing the liquid therefrom. The device further includes retainer devices for releasably retaining the elastic plates in their closed position.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
168 words
A device for dispensing a liquid from a collapsible container, comprising: a pair of elastic plates hingedly mounted to each other along one edge permitting them to be pivoted to an open position or to a closed position; a sleeve of flexible material secured to the pair of elastic plates along their hinged edges for receiving a liquid-filled collapsible container; each of said pair of elastic plates being pre-formed with a curve which is convex from the side facing said flexible sleeve such that when the liquid-filled collapsible container is received within said flexible sleeve and the two curved elastic plates are pivoted to their closed positions, they apply, due to their elasticity, a continuous force to the collapsible container for dispensing the liquid therefrom; each of said elastic plates being sectioned along parallel lines perpendicular to their hinged edges such as to permit compact folding of the assembly when not in use; and retainer means for releasably retaining said pair of elastic plates in their closed position.
Claim 2
Independent Claim
168 words
A device for dispensing a liquid from a collapsible container, comprising: a pair of elastic plates hingedly mounted to each other along one edge permitting them to be pivoted to an open position or to a closed position; a sleeve of flexible material secured to the pair of elastic plates along their hinged edges for receiving a liquid-filled collapsible container; each of said pair of elastic plates being pre-formed with a curve which is convex from the side facing said flexible sleeve such that when the liquid-filled collapsible container is received within said flexible sleeve and the two curved elastic plates are pivoted to their closed positions, they apply, due to their elasticity, a continuous force to the collapsible container for dispensing the liquid therefrom; each of said elastic plates being sectioned along parallel lines perpendicular to their hinged edges such as to permit compact folding of the assembly when not in use; and retainer means for releasably retaining said pair of elastic plates in their closed position.
Claim 3
Dependent Claim
25 words
