A foam dispensing cap includes a cap body having a ceiling wall and a cylindrical side wall, and a partition member. An ejection pipe is erected on the upper surface of the ceiling wall. An air chamber is in the space below the ceiling wall. A liquid entry opening is in the partition member. In the air chamber, an air passage for flowing air within the air chamber and a liquid flow path for flowing the content liquid, which has passed through the partition wall and entered the air chamber, communicate with each other. The air passage and the liquid flow path are formed to merge, and a region ranging from the point of merging to the ejection pipe defines an air-liquid mixture flow path. When the squeeze container is tilted and squeezed, the content liquid is ejected in a foamy state from the leading end of the ejection pipe.

A piston pump for dispensing fluid from a closed container in which during the cycle of operation to dispense fluid, atmospheric air is discharged into the reservoir towards reducing a vacuum that might otherwise be created within the container.

A fluid product dispensing system includes a liquid pump and a pneumatic pump that forces fluid product and pressurized air through a foaming device. The foam mixture forces a dispensing valve, located downstream, to open and thereby distribute product onto a user's hands. A control system turns off the pumps and open a pressure relief valve in the pneumatic conduit lines to relieve the buildup of pressure. The dispensing valve automatically resets, i.e. closes, to prevent the leakage of product from the nozzle.

An infrared soap dispensing faucet structure comprises a shell and an automatic soap dispensing unit. The shell has a hollow vertical section with a first space and a hollow horizontal section with a second space. A water outlet and a soap outlet are arranged at an outer lower edge of the horizontal section. The water outlet has a first sensor and the soap outlet has a second sensor. The first sensor of the water outlet is provided for controlling the water outlet to be turned on and off. The shell and the automatic soap dispensing unit are integrated with each other so that a bathroom space is not in disarray and dirt remained on hands is not polluted a faucet or the automatic soap dispensing unit.

A foamer for use in dispensing a liquid product with a foam consistency includes a top cap, a closure, a housing, an air-flow diaphragm, a mesh screen and a valve structure. The closure includes a portion which is received by the cap and these two (2) cooperate to define a foam outlet. The housing is assembled into the closure and the diaphragm is assembled into the housing. The mesh insert is positioned adjacent the foam outlet. The valve structure is provided in two (2) embodiments, one being a duckbill valve with a corresponding holder and the other being a metering valve with a corresponding holder.

Exemplary embodiments of energy efficient foam pumps and dispensers are disclosed herein. An exemplary foam dispenser included a housing, a reservoir for holding a foamable liquid, a motor, a motor shaft, and a turbine air pump. The turbine air pump is connected to the motor shaft. A cam is also attached to the motor shaft and is used for driving a liquid pump. Liquid from the liquid pump and air from the turbine air pump are mixed in a mixing chamber and dispensed through an outlet nozzle. The touch-free foam dispenser further includes a sensor for sensing an object, circuitry for receiving a signal from the sensor indicative of an object being present and circuitry for energizing the motor to dispense fluid in the form of a foam.
