A manually operated dispenser of the type containing a diaphragm at the bottom of the bottle, such that when the diaphragm is compressed a quantity of fluid is dispensed above the bottle through a spout. This invention uses a unique diaphragm shaped like a blister, that is integrated into the bottle bottom with a slide-pin allowing the blister diaphragm to move up and down, but not side to side. The diaphragm seals to the bottle bottom during dispensing, but when the diaphragm is substantially compressed, the seal self breaks as the diaphragm edge expands radially from the diaphragm axis over bumps on the bottle bottom allowing the diaphragm to refill. At the fluid output of the spout is a channel valve nozzle that channels the fluid into a stream when the fluid flows, but when the fluid is not being dispensed, prevents fluid from flowing back into the bottle.

The invention claimed is: 1. A manual dispenser of the type comprising: a) a bottle of fluid, b) a diaphragm at internal bottom of said bottle, c) a tube and a spout in series attached to said diaphragm that communicates a measured quantity of said fluid within said diaphragm through said tube through said spout and out an exit end of said spout above said bottle and a cap of said bottle as said diaphragm is compressed manually by a pressing force on said spout and said tube, and d) a set of check valves to ensure said fluid flows one way out of said spout and allows said diaphragm to refill with said fluid when said pressing force is removed and said diaphragm returns to an uncompressed shape for the next dispensing cycle; the following improvements comprising: e) said diaphragm is a blister diaphragm having a top opening and a bottom opening that are more or less concentric to a vertical axis; when said blister diaphragm is pressed with said pressing force against said internal bottom, a bottom edge of said bottom opening forms a seal at said internal bottom and forces said fluid within said blister diaphragm up said top opening through said tube and said spout; said bottom edge expands substantially radially from said vertical axis over said internal bottom to a self-breaking means that breaks said seal to allow said blister diaphragm to refill when said pressing force is removed, f) a slide-pin to prevent said blister diaphragm, said tube, and said spout from wobbling during dispensing, but does not substantially impede flow of said fluid, g) a nozzle means that integrates a valve to allow said fluid to flow in one direction and a channel to confine said fluid into a stream; whereby, said dispenser can be made from as few as five parts including said cap and said bottle; said parts are simple and have relaxed tolerances; fluid will not dry and clog said spout; and last ounce of said fluid will be dispensed. 2. The dispenser of claim 1 wherein said self-breaking means uses a plurality of bumps on said internal bottom outside but adjacent to said bottom edge such that said bottom edge lifts up to break said seal as bottom edge radially expands. 3. The dispenser of claim 1 wherein said self-breaking means uses a plurality of slits at said bottom edge that split open as said bottom edge radially expands across said internal bottom. 4. The dispenser of claim 1 wherein said self-breaking means uses a plurality of fulcrum bumps on bottom side of said blister diaphragm near said bottom edge such that as said bottom edge expands radially, said seal at said bottom edge is leveraged up until said seal breaks. 5. The dispenser of claim 1 wherein said self-breaking means uses a rough surface at said bottom edge of said blister diaphragm such that said fluid begins to flow through said seal as said bottom edge expands radially. 6. The dispenser of claim 1 wherein said slide-pin is one or more vertical legs attached to said internal bottom at said vertical axis of said blister diaphragm that slides into said top opening to align said blister diaphragm to said internal bottom. 7. The dispenser of claim 1 wherein said slide-pin is a hollow vertical cylinder with one or more side slots, said hollow vertical cylinder is attached to said internal bottom of said bottle at said vertical axis of said blister diaphragm that slides into said top opening of said blister diaphragm to align said blister diaphragm to said internal bottom. 8. The dispenser of claim 1 wherein said nozzle means uses a sliding piston attached to a spring, said spring and said piston within said spout, end of said spring away from said piston attached to inside said spout, said piston forms a sliding seal at the inside diameter near said exit end of said spout, said piston has a side hole channel such that when said fluid flows as said blister diaphragm is compressed, said piston will move out of said exit end to allow said fluid to flow through said side hole channel, and when said fluid flow stops, said piston is pulled back by said spring to reform said sliding seal. 9. The dispenser of claim 1 wherein said nozzle means uses a leaf spring within a more or less vertical channel on an end plate, said end plate is permanently attached across said exit end of said spout with said vertical channel and said leaf spring outside said spout, said vertical channel has an orifice near the lower end of said vertical channel for said fluid to flow when said fluid is dispensed, said leaf spring is fastened at the upper end of said vertical channel and extends over said orifice to seal said orifice such that said leaf spring bends and lifts at the bottom end of said leaf spring as said fluid flows through said orifice and down said vertical channel, and said leaf spring closes back into said vertical channel to reseal said orifice when said fluid stops flowing. 10. The dispenser of claim 1 wherein said nozzle means uses a rubber-like sheet that is stretched over an aperture of said exit end of said spout to form an aperture seal, said spout has a thickened wall at the lower edge of said exit end that has a more or less vertical partial channel that extends from just below said aperture to the outside edge of said thickened wall, such that when said fluid flows, said rubber-like sheet lifts to allow said fluid to flow out of said aperture down said partial channel, and when said fluid stops flowing, said rubber-like sheet reforms said aperture seal. 11. The dispenser of claim 1 wherein a compression spring is inserted within said blister diaphragm to assist said blister diaphragm to return to said uncompressed shape. 12. The dispenser of claim 1 wherein a separate rod is used to transmit said pressing force to compress said blister diaphragm rather than said tube and said spout. 13. The dispenser of claim 1 wherein cap tabs on said cap and tube tabs on said tube, when said tube is rotated relative to said cap, said tube tabs engage said cap tabs to lock tube from being depressed, whereby said dispenser cannot be accidently dispensed during shipment. 14. A manual dispenser of the type comprising: a) a bottle of fluid, b) a diaphragm at an internal bottom of said bottle, c) a tube and a spout in series attached to said diaphragm that communicates a measured quantity of said fluid within said diaphragm through said tube through said spout and out an exit end of said spout above said bottle and a cap of said bottle as said diaphragm is compressed manually by a pressing force on said spout and said tube, and d) a set of check valves to ensure said fluid flows one way out of said spout and allows said diaphragm to refill with said fluid when said pressing force is removed and said diaphragm returns to an uncompressed shape for the next dispensing cycle; the following improvements comprising: e) said diaphragm is a double-blister diaphragm having a top opening, a bottom opening and a mid-section more or less concentric to a vertical axis, said mid-section is substantially larger than said top opening and said bottom opening, a bottom edge of said bottom opening has a rough surface; when said double-blister diaphragm is compressed by said pressing force against said internal bottom, said bottom edge forms a seal at said internal bottom and forces said fluid within said double-blister diaphragm up said top opening, through said tube, and through said spout, and said mid-section expands substantially radially from said vertical axis; when said pressing force is removed, said seal is broken by said rough surface to allow said fluid to refill said double-blister diaphragm, f) one or more vertical legs attached to said internal bottom of said bottle at said vertical axis of said double-blister diaphragm that slides into said top opening to align said double-blister diaphragm to said internal bottom, g) a nozzle means that integrates a valve to allow said fluid to flow in one direction and a channel to confine said fluid into a stream; whereby, said dispenser can be made from as few as five parts including said cap and said bottle; said parts are simple and have relaxed tolerances; fluid will not dry and clog in said spout; and last ounce of said fluid will be dispensed. 15. The dispenser of claim 14 wherein a compression spring is integrated within said double-blister diaphragm to assist said double-blister diaphragm to return to said uncompressed shape. 16. The dispenser of claim 14 wherein said nozzle means uses a sliding piston attached to a spring, said spring and said piston within said spout, end of said spring away from said piston attached to inside said spout, said piston forms a sliding seal at the inside diameter near said exit end, said piston has a side hole channel such that when said fluid flows as said double-blister diaphragm is compressed, said piston will move out of said exit end to allow said fluid to flow through said side hole channel, and when said fluid flow stops, said piston is pulled back by said spring to reform said sliding seal. 17.
