There is shown a hand operated fluid and/or powder dispenser and as an preferred embodiment includes a plastic squeeze container having longitudinally fluted ribs for easy collapsing. In the interior there is carried a flexible feeding tube having an end which lies against the bottom of the container. This tube has a weighted enlarged inlet formed with a multiplicity of channels. This container is filled with fluid or powder and has a screw cap retainer in which is mounted a ball valve. This valve is movable to two limits. At an inner limit air or atmosphere flows inwardly when the container is allowed to relax to its molded condition. When the container is squeezed a ball valve is moved to a closed condition whereby airpressure rapidly builds up within the container and the fluid or powder is caused to flow through the flexible tubing to a directing spout. This spout is readily mounted in the cap portion and is movable in relation to the cap by a knurled or fluted knob. In an alternate embodiment the spout may have a fan-like flare exit by which powder is sprayed or distributed from the container. The end of the inlet tube is constructed so as to have a weighted cap inlet which in one embodiment is snapped in place on a shoulder and in another instance is a solid metal disk secured in place in a recess formed in an inlet end.

A hand held squeeze dispenser for fluid and/or powder which includes: (a) a flexible container having an outlet at one end and with the sidewall portions thereof longitudinally fluted so as to be readily collapsible by manipulation such as squeezing to reduce the interior volume of the container, said container having the sidewall portion sufficiently stiff to return unassisted to an “as formed”condition and shape after said collapsing actuation; (b) a closure cap mounted on the outlet of the container, said mounted cap adapted to retain the contents of the container absent spillage and leakage when and while the container is maintained in substantially an upright condition; (c) an outlet of generally tubular construction formed in and on said cap so as to receive and retain a discharge spout; (d) a valve carried in said cap and adapted to close under the influence of air being moved from the container as the container is collapsed and to open and pass air into the interior of the container through said valve when the container is relaxed to resume and assume said “as formed”condition; (e) a conduit retainer of generally tubular configuration and formed on the inner side of the cap, said conduit retainer in flow communication with the outlet of the cap; (f) a flexible plastic tubing attached to said conduit retainer on the inside of the cap, said flexible tubing providing a flow passageway through said tubing, the conduit retainer and thence to the outlet, said flexible tubing of a length sufficient to bring its unconnected end to at least a proximate relationship with the bottom of the container when and while in a stored condition; (g) an enlarged end provided on the unconnected end of the flexible tubing, said enlarged end being a molded component with a substantially central passageway extending to the flexible tubing and providing a common conducting flow passageway from the enlarged end to the flexible tubing, said enlarged end and the central passageway including radially disposed grooves formed in an open face portion of the enlarged end, said grooves extending from the outer periphery of the enlarged end to the substantially central passageway, and (h) a cover member and means for securing said cover to the open end of said enlarged end, said cover so constructed and configured that when secured the grooves are covered except for their outer end portions and providing radial conducting paths, said enlarged end and cover providing sufficient weight to carry the flexible tubing and its connected enlarged end to the bottom of the container when and while in a substantially upright condition.
