Abstract
Abstract 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.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
54 words
A liquid sprayer comprising: a rotatable container, said container having a receptacle for holding a quantity of liquid, a liquid pressurizing chamber adaptable to receive a charge of liquid, and an opening for filling said receptacle with liquid; an inlet conduit in said container for conducting said charge from said receptacle to said chamber;
Claim 2
Dependent Claim
54 words
A liquid sprayer comprising: a rotatable container, said container having a receptacle for holding a quantity of liquid, a liquid pressurizing chamber adaptable to receive a charge of liquid, and an opening for filling said receptacle with liquid; an inlet conduit in said container for conducting said charge from said receptacle to said chamber;
Claim 3
Dependent Claim
24 words
The sprayer of claim 1 wherein said compressible means is a biasing member contacting said piston and urging said piston away from said cap.
Claim 4
Dependent Claim
32 words
The sprayer of claim 1 further including means mounted under said spray nozzle for rendering said nozzle inoperable in one of two positions and operable in the other of said two positions.
Claim 5
Dependent Claim
12 words
The sprayer of claim 1 wherein the charging means is a cam.
Claim 6
Dependent Claim
15 words
The sprayer of claim 1 wherein the first fluid control means is a check valve.
Claim 7
Dependent Claim
15 words
The sprayer of claim 1 wherein the second fluid control means is a check valve.
Claim 8
Dependent Claim
12 words
The sprayer of claim 2 wherein the biasing member is a spring.
Claim 9
Dependent Claim
12 words
The sprayer of claim 7 wherein the spring is a coiled spring.
Claim 10
Dependent Claim
12 words
The sprayer of claim 7 wherein the spring is a flat spring.
Claim 11
Dependent Claim
16 words
The sprayer of claim 1 wherein said opening for filling said receptacle is a recloseable plug.
Claim 12
Dependent Claim
250 words
A liquid sprayer comprising a rotatable container, said container having a receptacle for holding a quantity of liquid, a liquid pressurizing chamber, and an opening for filling said receptacle with the liquid; an inlet conduit in said container for conducting liquid from said receptacle to said chamber; an inlet check valve in said conduit permitting liquid flow into said chamber; an air inlet check valve in said container permitting air flow into said receptacle; a sprayer cap rotatably connected to said container; a movable piston in said cap; cam means in said container operatively contacting a portion of said piston for moving said piston in said cap in response to rotation of said container relative to said cap; a spray nozzle in said cap for discharging said liquid from said container; an outlet conduit for conveying said liquid from said chamber to said spray nozzle; a discharge valve in said outlet conduit for controlling discharge of liquid from said chamber through said nozzle; conduit means in said piston connected to said outlet conduit and said pressurizing chamber for conveying liquid from said chamber to said outlet conduit and to said spray nozzle; and, responsor means in said cap contacting said piston in a biasing relationship such that said piston is urged away from said cap and into said pressurizing chamber whereby liquid therein is displaced by said piston in said chamber and forced to flow into said conduit means, into said outlet conduit and said spray nozzle for discharge thereat.
Claim 13
Dependent Claim
250 words
A liquid sprayer comprising a rotatable container, said container having a receptacle for holding a quantity of liquid, a liquid pressurizing chamber, and an opening for filling said receptacle with the liquid; an inlet conduit in said container for conducting liquid from said receptacle to said chamber; an inlet check valve in said conduit permitting liquid flow into said chamber; an air inlet check valve in said container permitting air flow into said receptacle; a sprayer cap rotatably connected to said container; a movable piston in said cap; cam means in said container operatively contacting a portion of said piston for moving said piston in said cap in response to rotation of said container relative to said cap; a spray nozzle in said cap for discharging said liquid from said container; an outlet conduit for conveying said liquid from said chamber to said spray nozzle; a discharge valve in said outlet conduit for controlling discharge of liquid from said chamber through said nozzle; conduit means in said piston connected to said outlet conduit and said pressurizing chamber for conveying liquid from said chamber to said outlet conduit and to said spray nozzle; and, responsor means in said cap contacting said piston in a biasing relationship such that said piston is urged away from said cap and into said pressurizing chamber whereby liquid therein is displaced by said piston in said chamber and forced to flow into said conduit means, into said outlet conduit and said spray nozzle for discharge thereat.
