Abstract: 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.

Abstract: A dispenser that represents the next generation of manually activated fluid dispensers found in homes at kitchen and bathroom counter tops that dispense soap, creams, and lotions. Shown in FIG. 1, the invention uses a diaphragm 105 positioned at the bottle bottom 109 of a bottle 101 filled with fluid (not shown) that is manually activated to push fluid through a tube 107, spout 111, and check nozzle 112 for the following advantages: much less expensive with fewer simpler parts, no drying of fluid in the spout 111, no dripping, and is capable of dispensing the last ounce of fluid left in the bottle. The diaphragm 105 has a unique feature that allows fluid to be pushed through the tube/spout/nozzle (107/111/112) and refill with fluid as the diaphragm is compressed and released respectively. This dispenser is activated by pushing down on a thumb saddle 113 attached to the spout 111 and tube 107.
