Abstract
A device for the spraying of liquids includes an air compressor or pump driven by a weight activated by shaking the device in an essentially vertical direction. The device consists of a resuable liquid module containing a liquid to be sprayed; a pump module attached to a screw cap for the liquid module and contained within the liquid module; a compressed air duct connecting the outlet of the air pump to the liquid module and a fluid conduit conducting the fluid to be sprayed from the liquid module to the outlet valve for discharge under the influence of the compressed air.
Claims13
An improved apparatus for discharging liquids in a spray, wherein the improvement comprises:
- a. a pump module containing a pumping means, said pumping means being capable of supplying compressed air;
- b. a liquid module containing a liquid to be sprayed, wherein said liquid module contains said pump module within the confines of said liquid module;
- c. a first conduit disposed within said liquid module and a coupling extension attached to said pump module, said coupling extension providing a connection between said pump module and said liquid module for the transfer of compressed air to said liquid module;
- and,
- d. a second conduit and an outlet valve, said second conduit conducting the liquid to be sprayed from said liquid module to said outlet valve for discharge, the liquid to be sprayed flowing in response to urging by said compressed air,
- wherein said liquid module comprises a refillable dispenser provided with a threaded sealing cap;
- e. said threaded sealing cap being attached to said pump module;
- f. said pump module being insertable and removable with respect to said liquid module when said sealing cap is respectively applied to and removed from said liquid module, thus permitting use of a variety of liquid module shapes and sizes as may be commercially available.
An improved apparatus for discharging liquids in a spray, wherein the improvement comprises:
- a. a pump module containing pumping means, said pumping means being capable of supplying compressed air;
- b. a liquid module containing a liquid to be sprayed, wherein said liquid module contains said pump module within the confines of said liquid module;
- c. a first conduit disposed within said liquid module and a coupling extension attached to said pump module, said coupling extension attached to said pump module, said coupling extension providing a connection between said pump module and said liquid module for the transfer of compressed air to said liquid module;
- d. a second conduit and an outlet valve, said second conduit conducting the liquid to be sprayed from said liquid module to said outlet valve for discharge, said liquid to be sprayed flowing in response to urging by said compressed air;
- e. wherein said pump module contains a pumping means comprising a weight of a weight activated pump with a piston of a cylinder-and-piston arrangement for compressing air;
- f. said piston being capable of compression strokes, wherein the sequential inertial impulses provided by said weight drive said piston in its compression strokes within a guide means;
- g. said pumping means further being provided with two check valves and,
- h. a conduit for admitting air into said pump module to be compressed, said conduit being open to the outside air through a sealed aperture traversing a threaded sealing cap.
An improved apparatus for discharging liquids in a spray, wherein the improvement comprises:
- a. a pump module containing pumping means, said pumping means being capable of supplying compressed air;
- b. a liquid module containing a liquid to be sprayed, wherein said liquid module contains said pump module within the confines of said liquid module;
- c. a first conduit disposed within said liquid module and a coupling extension attached to said pump module, said coupling extension providing a connection between said pump module and said liquid module for the transfer of compressed air to said liquid module;
- d. a second conduit and an outlet valve, said second conduit conducting the liquid to be sprayed from said liquid module to said outlet valve for discharge, said liquid to be sprayed flowing in response to urging by said compressed air;
- e. wherein said pump module contains a weight activated pumping means including a tapered bellows with said tapered bellows being capable of compression strokes, wherein the sequential inertial impulses provided by a driving weight drive said tapered bellows in its compression strokes.
