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, the valve device 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 the profiled opening such that relative rotation of the inner and outer sleeves causes the butterfly valve member to rotate between a closed state in which the butterfly valve member closes the through passage by substantially filling an internal cross section of the through passage and an open state in which the through passage is open.
