1. A dispenser comprising, in combination,a dispenser housing defining an interior chamber and including side walls and a bottom wall having an opening therein, and a front, general vertical wall,a disposable flexible fluid impervious container adapted to contain flowable product in substantially sealed relation therein, said container having an outlet opening through which said product may be removed from said container,means cooperable with said container and said housing to releasibly support said container within said chamber so that said product is urged toward said outlet opening under the influence of gravity,means defining an additional opening in said housing to admit said disposable container for attachment to said means for releasably supporting said container,a disposable compressible discharge tube affixed to said container adjacent said outlet opening and having flow communication with product within said container,a disposable discharge fitment mounted on an end of said discharge tube opposite said container and having a discharge orifice in flow communication with said discharge tube, said fitment being adapted for releasable cooperation with said housing so as to maintain said discharge fitment in predetermined relation to said housing,a rotor rotatably supported within said housing for cooperation with said discharge tube so as to effect flow of product through said discharge tube from said container upon selective rotation of said rotor,an actuating handle located at said front wall above said discharge fitment and cooperable with said rotor and operable to rotate said rotor with a downward pull on said handle through a predetermined stroke so as to effect a substantially predetermined quantity discharge from said container upon each actuating stroke of said handle, said discharge fitment being located beneath said handle,a cam plate pivotally mounted on said housing adjacent said opening in the bottom wall and having an arcuate cam surface thereon, said cam plate being pivotally movable independently of said housing between a first position enabling loading of a flexible container and associated discharge tube within said chamber and a second position wherein said cam surface is positioned for cooperation with said discharge tube so as to effect occlusion of said discharge tube during rotation of said motor,and means selectively cooperable with said housing and said cam plate for releasably retaining said cam plate in its said second position.
