Patent

CA 2148757

A valve device for connecting a container filled with a flowable material to an applicator device for dispensing the flowable material comprises a unitary, essentially cup-shaped housing 1 having an axially extending flow passage 9 in the base thereof. A valve seat 50 is formed around the inner end of the flow passage 9, radially inwardly of the axially extending wall 8 of the housing 1. A unitary, essentially cylindrical valve member 2 is received in the open end of the cup-shaped housing 1. This has an axially extending flow passage 16 therein in axial alignment with the flow passage 9 in the cup-shaped housing 2. A valve disc 14 is positioned over the inner end of the flow passage 16, but spaced therefrom. The valve member 2 is axially displaceable relative to the housing 1 upon rotational movement of the housing 1 so as to effect engagement of the valve disc 14 with the valve seat 50 to close the flow passage 9 in the housing 1 and disengagement to open the flow passage 9 in the housing 1. In use, the housing 1 is connected to the discharge orifice of the container and the valve member 2 is connected to the receiving orifice of the applicator.
