Abstract:
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 extending fully across the base housing and 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 removably insertable reservoir head having a head top, a head bottom, a circular head wall between said head top and said head bottom and perpendicularly disposed to 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 and completely encircling said head bottom, wherein said bottom slot seats onto and into the top of and completely around 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) 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 chamber cap is pressed into said lower chamber, said electro-chemical gas generating means is activated generating gas into said upper chamber forcing fluid out of said bladder onto said pad.
