Portable dispensing system
First Claim
1. A portable dispensing system comprises:
- a hollow body having a first and second open end, said hollow body receiving a flexible pouch comprising a main body made of a flexible material and a flexible discharge portion integral with said main body, said pouch being filled with a flowable material;
a head removably mounted at said first end of said body and having an opening therethrough;
piston means mounted at said second end of said body for applying pressure to the flowable material in said pouch;
said head including valve means adapted for opening in response to pressure created by said piston means acting on said flowable material in said pouch means, said valve means being mounted on said head adjacent said opening and comprising a casing, jaw means movably mounted on said casing for reciprocable movement between opened and closed positions, said discharge portion of the pouch passing through said opening of said head and being engaged by said jaw means, biasing means normally urging said jaw means to the closed position thereby closing said pouch and said biasing means yielding due to pressure increases on said pouch by said piston for the discharging of said flowable material.

Abstract
A portable dispensing system includes a hollow body having two ends. A head is removably mounted on one end of the body and has an opening therethrough. A piston mechanism is removably mounted at the other end of the body. A valve mechanism for opening in response to pressure created by the piston mechanism is mounted on the head adjacent the opening. The valve mechanism includes a casing, a jaw slidably mounted on the casing for movement between an opened and closed position, and a spring mechanism urging the jaw to the closed position and yielding to pressure increases in the body. A flexible pouch is provided for receipt in the body. The pouch includes a main body made of a flexible material and a discharge portion which is integral with the main body. The discharge portion is capable of passing through the opening of the head and is for engagement with the jaw. Preferably, the pouch is fitmentless.

7. A portable dispensing system for condiments and the like comprises:
-
a hollow body having a first and a second open end, said hollow body receiving a flexible pouch comprising a main body made of a flexible material and a flexible discharge portion integral with said main body, said pouch being filled with a flowable material; a head removably mounted at said first end of said body and having an opening therethrough; piston means mounted at said second end of said body for applying pressure to the flowable material in said pouch; said head including valve means adapted for opening in response to pressure created by said piston means acting on said flowable material in said pouch, said valve means being mounted on said head adjacent said opening and comprising a casing, two opposed jaws mounted in said casing for sliding movement which is perpendicular to said opening and for movement between opened and closed positions, said discharge portion of the pouch passing through said opening of said head and being engaged by said jaws, biasing means associated with each said jaw and normally urging said jaws to said closed position and yielding due to pressure increases in said pouch by said piston for the discharging of said flowable material.
