Abstract
Abstract A hand holdable, disposable dispension container of low cost construction, generally of plastic, for the dispensing of fluent, generally viscid materials, including processed foodstuff such as ketchup, relish, mustard and jams; creams, handcreams, lotions, colloidal solids such as toothpaste and the like, has a base portion on which the container is free standing, and a valved dispensing outlet located on a lower side face of the container, in underhung protected relation adjacent to the base, to permit downward dispensing of selected quantities of the contents without having to resort to invention of the container. The container incorporates a self-venting pressure balance capability. The container content is always located in the lower part of the container, due to the influence of gravity for immediate dispensing, by squeezing of the container walls, and making possible the dispensing of substantially all of the contents so that virtually none is wasted and thrown out with the container.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
176 words
Valve means for use with a pressurizable container having an aperture therein, comprising: collar attachment means for securing the valve means to the aperture in the container; aperture closure means providing an outlet aperture of limited cross sectional area; and deflectable valve means normally extending in a first position in sealing relation across said outlet aperture and movable away from the outlet aperture to a second, open position in response to pressure within the outlet aperture acting on the valve means, said deflectable valve means having at least one portion thereof serving as a spring to apply closing force thereto to move the valve means from said second position to said first position upon release of pressure within said outlet aperture, said valve disabling means comprising a pair of spaced abutments receiving a portion of said spring in cantilevered relation therebetween when in said first, withdrawn position, and in said second position having one of the abutments positioned in pressing relation with the valve means, to secure the valve means in the first said position thereof.
