ELECTROCHEMICAL DISPENSER
First Claim
1. A device for dispensing fluids automatically comprising:
- (a) a base housing having a top surface, a bottom, an upper chamber within said base housing, a lower chamber within said base housing below said upper chamber, a chamber ledge separating said upper chamber from said lower chamber wherein said chamber ledge has a gas exit port, and a removably insertable chamber cap on the bottom of said base housing covering said lower chamber;
(b) a reservoir head having a head top, a head bottom, a head wall between said head top and said head bottom with a groove therearound, a collar extending downward from said head bottom having a collar bottom with a fluid exit port from said collar bottom through said head top, an inner chamber above said head bottom between said outer wall and said collar, and a bottom slot on said head bottom adjacent to said collar, wherein said bottom slot seats onto and is attached to the top of said base housing;
(c) a bladder on said collar for holding fluid therein, said bladder comprised of a flexible material which is substantially gas impermeable and liquid impermeable;
(d) a pad in said reservoir head above said collar and within said inner chamber;
(e) a reservoir cap having a closed top, a side wall extending downward from said closed top, and an open bottom, wherein a shoulder protrudes inward from said side wall and is in closing communication with said groove; and
(g) electrochemical gas generating means for generating gas, said gas generating means contained and sealed within said lower chamber such that as gas is generated said gas cannot escape from said lower chamber except through said gas exit port and into said upper chamber;
whereby as said chamber cap is pressed into said lower chamber, said electrochemical gas generating means is activated generating gas into said upper chamber forcing fluid out of said bladder onto said pad.

Abstract
A device for achieving a controlled low emanation rate of small volumes of liquid solutions, such as single or multi-component solutions, fragrances, or pheromones, for pest and insect management or fragrance enhancement. The device has a housing with an upper chamber to hold a bladder containing desired liquid solution to be released, a lower chamber containing an electrochemical gas generator, a collector pad for receiving liquid solution from the bladder, and a cap which, when translated downward, activated the gas generator which fills the upper chamber with gas exerting pressure on the bladder which in turn forces the liquid solution from the bladder onto the pad for release to the environment. The gas generator is capable of releasing gases such as hydrogen, oxygen, or carbon dioxide at extremely small, pre-determined, and adjustable rates.

18. A device for dispensing fluids automatically comprising:
-
(a) a base housing having a top surface, a bottom, a cut-out on said top surface, an inner side wall on each side of said base housing defining a central chamber and a side chamber on each side of said central chamber, and an annular ring on the bottom inside of said base housing; (b) an inner body having an upper chamber, a lower chamber, a chamber ledge separating said upper chamber from said lower chamber wherein said chamber ledge has a gas exit port; (b) a reservoir head having a head top, a head bottom, an annular collar extending downward from said head bottom, a fluid exit port within said collar; (c) a bladder on said collar for holding fluid therein, said bladder comprised of a flexible material which is substantially gas impermeable and liquid impermeable; (d) a pad in said reservoir head above said head top, said pad having a pad aperture in communication with said fluid exit port; (e) a reservoir cap having a top, a downward extending wall from said top defining an inner surface therein, and a plurality of vents on said downward extending wall; and (g) electro-chemical gas generating means for generating gas, said gas generating means contained and sealed within said lower chamber such that as gas is generated said gas cannot escape from said lower chamber except through said gas exit port and into said upper chamber; whereby as said reservoir cap is pressed downward, said lower chamber of said inner body seats around said annular ring causing said electro-chemical gas generating means to become activated generating gas into said upper chamber forcing fluid out of said bladder onto said pad. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
