ABSTRACT:
A liquid dispensing device incorporates a housing for mounting on a shower, bath enclosure, or other appropriate wall. The housing houses a plurality of refillable and sealable bottles that conform to the interior contour of the housing in order to maintain a narrow and streamlined profile to the housing. Each of the bottles comprises a supply reservoir, a dispensing reservoir, a transition area connecting the two reservoirs, and a dispensing pump mechanism that dispenses a measured amount of fluid from the dispensing reservoir. The pump injects an amount of ambient pressure air into the closed bottle equal to the amount of liquid dispensed, with each dispensing cycle, to equalize and maintain the pressures inside and outside the bottle to prevent collapse of the bottle as liquid is withdrawn. This equalization of pressure prevents liquid from inadvertently seeping through the pump under its own weight.
