1. An apparatus for dispensing a viscous material, the apparatus comprising:
a dispensing gun including a plunger;
a container for holding the viscous material, the container comprising a first end having a nozzle, a second end opposite the first end, and a bottom cap recessed within the second end, wherein the bottom cap is configured to be shifted from the second end toward the first end of the container upon pushing of the plunger into the second end of the container to dispense the viscous material from the nozzle during use of the dispensing gun; and
a resiliently deformable member including a compression spring interposed between first and second slidable cap enclosures, said resiliently deformable member being at least partially recessed within the second end of the container and entirely between the bottom cap and the plunger, the resiliently deformable member having a relaxed state and a compressed state, wherein the resiliently deformable member is configured to shift between the relaxed and compressed states to modulate a flow of the viscous material from the container when the dispensing gun is in use.
