Container

Abstract

Problem A container for viscous substances, especially liquids, is typically operated such that discharge is effected by, for example, folding or pumping action exerted by a means provided atop the container. Complete emptying of a conventional container in most cases cannot be achieved. Some residues may be removed by the action of gravity. However, for substances of higher viscosity, retrieving residues from the container remains a challenge. Furthermore, the shelf life of the fluid may be adversely affected by ambient air entering the container as it is being emptied. The invention aims to facilitate an almost complete discharge of a container, regardless of gravity. Moreover, the viscous fluid is to be preserved in vacuum to prolong its shelf life. Solution Container for a preferably viscous fluid having a compressible, preferably elastic, outer body (1) and an inner body (2) opening out of the container and comprising the fluid, characterized in that captive air is enclosed between the outer body (1) and inner body (2) and the inner body (2) is affixed within the outer body (1) such that when compressive force is applied upon the outer body (1), the captive air transfers the force unto the inner body (2), displacing and discharging the fluid from the container.
