• 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.
