ABSTRACT:
The dispensing device has an open ended cylinder member for receiving a can container having an open end supported on an annular shoulder at one end of the cylinder member. A cup shaped piston, extendible and retractible relative to the other end of the cylinder member carries a piercing member to pierce a hole in the closed end of the can on an initial retraction of the cup shaped piston within the cylinder member. A second retraction of the piston applies a pressure on the material in the can for discharge from its open end into a material receiving chamber from where it is ejected into a feeding dish. An air bleed hole in the piston is open during the piercing operation and manually closed when material is to be discharged from the can.
