Abstract: A valve device has an outer sleeve with a first end to be secured in an orifice of a container. A second end is releasably attached to a receptacle. Walls define a generally cylindrical support passage which extends from said first end to said second end. An inner sleeve is within the support passage with walls defining a generally outer surface adjacent the walls of the outer sleeve. The walls rotatably support the inner sleeve and define an internal through passage. A butterfly valve member is in the through passage. The butterfly valve has diametrically opposed first and second pivot stubs which extend at least into the walls of the inner sleeve to rotatably support the butterfly valve. The walls of the outer sleeve have a profiled opening into which the first pivot stub extends. The first pivot stub includes a cam member which interacts with the profiled opening. Relative rotation of the inner and outer sleeves causes the butterfly valve member to rotate between a closed state and an open state.

Abstract: A valve device, for connecting a container filled with a flowable material to a receptacle and for dispensing the flowable material from the container into the receptacle, including an outer sleeve having a first end to be secured in the orifice of a container, a second end for releasable attachment to a receptacle and walls defining a generally cylindrical support passage extending from said first end to said second end, an inner sleeve within the support passage having walls defining a generally outer surface adjacent the walls of the outer sleeve so as to rotatably support the inner sleeve and defining an internal through passage, and a butterfly valve member within the through passage having diametrically opposed first and second pivot stubs extending at least into the walls of the inner sleeve so as to rotatably support the butterfly valve, the walls of the outer sleeve including a profiled opening into which the first pivot stub extends, the first pivot stub including a cam member which interacts with t

Abstract: A portable applicator for dispensing flowable material from a container, the applicator comprising a carrying frame for wearing by a user and for supporting a container such that a valve of the container faces substantially downwardly; an inlet mounted to said carrying frame for sealable engagement with a valve of a container for receiving material from the container when the valve thereof is in an open condition thereof; and a dispenser outlet communicating with said inlet for dispensing material received via said inlet.
