ABSTRACT:
A valve mechanism for dispensing viscous, sticky materials from a container having a neck defining a discharge opening. The valve is formed by a tubular body threaded at one end for engaging the container neck. A normally closed spring biased valve in said body controls the discharge of material from said container. The valve body defines a spheroidal dispensing cavity opening through one end thereof for accessibly retaining for subsequent use an increment of material discharge from the container through the valve. In an alternative version, a ball valve is so seated as to preclude wedging of the material into the valve seat.
