An automatic dispensing cap for dispensing product contained in a squeeze-type container. A two-way valve-head comprising an upper disc closure is constructed so that it seats on the top edge of the inverted conical spout of the cap. In a preferred embodiment, the disc closure has a centrally-located air bore and depending tubular stem. Upon application of manual squeeze pressure, the valve-head unseats from the cap spout allowing product to flow through. When the squeeze pressure is released, a lower cruciform portion of the two-way valve-head acts as a spring to seat the upper disc closure, cutting off the flow of product, and allowing air to reenter the container through the central disc air bore and the tubular stem. An inverted cup-shaped check-valve closes the central air bore of the tubular stem during the dispensing phase, to prevent product from exiting therethrough. In another embodiment, primarily useful with a squeeze tube, the central disc and central stem are solid; and the check-valve is eliminated.

A reciprocating type of finger pump for use on top of a product container. This combines a tubular housing, including a laterally directed spray nozzle, mounted coaxially in the sleeve of an accumulator cap including a central valve. The valve opening leads to a dip tube which passes into a liquid reservoir in the container. The tubular housing, including the spray nozzle, is depressed manually so that it moves telescopically in the accumulator sleeve, driving a hollow piston against the tension of a spring. The first compression stroke serves to prime the pump, forcing a piston to close the valve to the dip tube. Simultaneously, air in an annular chamber of the housing surrounding the hollow piston is compressed. On the reverse or suction stroke, the valve to the dip tube is opened, creating a vacuum which causes the liquid to be sucked up from the reservoir and into the hollow piston. On the second or subsequent compression strokes, the compressed air and liquid are forced through normally closed pressure responsive seals into the inner mixing chamber, where the compressed air breaks up and atomizes the liquid, causing the atomized spray to move at high pressure through the spray nozzle.

An improved dispenser for cosmetic stick solids such as deodorants constructed to be filled in either normal or inverted position. This dispenser is cylindrical having walls of substantially uniform diameter, an open top, and substantially closed bottom. The dispenser is constructed so that the dispensing means is either pushed up manually, or propelled by a screw-mechanism. In the latter case a long screw is mounted in a central opening in the bottom, and continues along the axis of the cylinder. The cap of the dispenser may assume either of two forms, a snap-on type, or a screw-on type, each exhibiting an air-tight seal. The snap-cap is constructed to include a plurality of cams which operate in conjunction with similar members on the mouth of the cylindrical container to provide relative ease in opening and closing the snap-cap. The dispenser is designed to be filled in a conventional manner from the opening in the top, or, alternatively, from a hole in the bottom of the cylindrical container. In the latter case an inside liner disposed between the cap and the mouth of the cylindrical container retains the product during the filling process.

A manually operated, hand-held, rechargeable, liquid spraying device having a non-pressurized, refillable or non-refillable container, is disclosed. The sprayer, a completely contained device, comprises a charging mechanism whereby, upon rotation of one part relative to another part, a movable piston is displaced vacating a charge chamber which, simultaneously, is charged with liquid. Displacement of the piston compresses a responsor or spring which, in turn, causes the piston to exert a hydraulic pressure on the liquid now in the chamber vacated by the piston. Hydraulic pressure on the charge chamber liquid is maintained by the closing of a one-way, elastomeric resilient valve in the entrance in the chamber, which closing occurs when the piston halts in its movement. A push botton flow control valve, when operated, permits liquid to flow from the charge chamber to an outlet nozzle through associated conduit means, being urged therethrough by the piston which is moved back into the charge chamber under the urging of the responsor or spring.

A manually operated, hand-held liquid spraying device which includes a non-pressurized, refillable or non-refillable container, is disclosed. The sprayer is a completely contained device wherein an internal cam in one part of the device which is rotated, causes a displacement of a piston, a part of which is a cam follower. Piston displacement vacates a chamber which is simultaneously charged with liquid. The piston is moved as a result of the cammed motion against a responsor biasing it. The biased responsor generates a hydraulic pressure on the liquid now in the chamber vacated by the piston, since a check valve traps the liquid in the chamber. The liquid is released from the chamber by depressing a push button device, which action uncovers a port in an outlet conduit permitting liquid to flow from the chamber through the conduit and out through a flow connected nozzle in response to the responsor-urged piston moving down through the liquid in the chamber. .

Sprayer for fluid product in which a hand-actuated trigger forces a hollow piston mounted to move in vertical reciprocating fashion in a stationary tubular accumulator, against the compression of a spring. The product is forced upward and out through a swirl chamber adjacent the spray nozzle. Additional product is siphoned up into the accumulator by the partial vacuum created by the return of the piston to its rest position. Alternative embodiments, including both a vertically and horizontally directed sprayer, feature an annular flexible flange seating against an annular skirt below a swirl chamber, which keeps air out of the product chamber and deflects inwardly to release product under pressure. Additionally, a horizontally-directed spray-head may be attached to the vertical trigger sprayer for the purpose of converting the latter to a horizontal sprayer. Further embodiments comprise modification of the annular flexible flange including separate flange-type components which may be force-fitted into the accumulator top, and are constructed to tangentially seal against the annular skirt and deflect to release product.

A moisture proof safety container for pills and the like in which a drawer moves slidably in a rectangular cover, snap-locking closed by means of a latching mechanism comprising a hooked tongue which engages a small window in the upper left-hand corner of the cover. The drawer, including the hooked tongue, is guided into latching position with the cover by means of a fulcrum point located on the inside of the cover which bears against one side of the drawer. When the drawer is closed a small projection at the center of the cover seats on the bottom of the drawer, cooperating with a small bead around the rim of the drawer, and small feet in the corners, to produce a moisture proof seal.
