The apparatus includes an open entry disposable hose and forcing bag which are formed integrally with each other. At the end extreme from the feeding means, the bag includes a bulbous member. Several embodiments of the integral hose and bag are shown and described. When required, a venting hose is provided for release of trapped air in the material and communicates with an expansion chamber. In certain circumstances, a tube surrounds the bag and is selectively inflatable or deflatable for controlling dispensing of the material in predetermined amounts while still using, for example, a continually fed supply of material to the forcing bag.
