ABSTRACT:
A valve assembly for dispensing a measured quantity of a gelatinous semisolid material into a receptacle comprises a cylindrical housing provided with a piston actuatable to move through the throughbore of the housing to a cap provided with a cylindrical sleeve. Mounted within the sleeve is a hollow valve body connected to a sealing member having an end of circular cross-section and a slidable hollow cylindrical body provided with an orifice whose cross-section is substantially equal to that of the end of the sealing member. The barrel is connected to the valve body by springs. In the valve closed position the end of the sealing member is situated in the barrel orifice, preventing the dispensing of the gelatinous material; in the valve open position the barrel is pushed away from the sealing member, allowing the material to be dispensed. The barrel returns to the valve closed position after the material has been dispensed. In use, the material is introduced into the housing; weighing the valve assembly before and after dispensing enables the quantity of dispensed material to be verified.
