Abstract: Disclosed is a multi-compartment pressure pouch for use in a container pressure generation system. The outer sheets of the pressure pouch are formed from a relatively highly deformable material, so that the pressure pouch may conform to the interior of a container having virtually any shape. The highly deformable material may be chosen such that its yield strength is greater than the force required to open each pouch compartment.

Abstract: An automatic soap dispenser (10) includes a disposable soap container including a dispensing mechanism (20) in which walls of an interior chamber (56) cooperate with a diaphragm (62) and a plunger (66) to form a transit chamber (64), which is resiliently expandable against the force of a spring (80). When a solenoid (58) permits the diaphragm (62) to move away from the outlet of a passage (50) in a flow path from the interior of a pressurized reservoir (18) to the expandable transit chamber (64), travel of the plunger (66) permits the transit chamber (64)'s pressure-relieving outlet opening to expand so that the pressure within the transit chamber (64) is determined predominantly by the force of the spring (80) rather than by the pressure within the reservoir (18). The velocity of the liquid dispensed from the transit chamber (64) through the dispensing mechanism's spout (16) is therefore relatively independent of the pressure within the reservoir (18).

Abstract: A dispensing system is provided which assists in preventing oxidation of a product having an oxygen labile component. The system comprises a container having an internal chamber and a neck providing access to the internal chamber. A pump is attached to the neck of the container.

The released gas provides two advantages. First, the gas serves to keep internal pressure of the system at a constant level. Second, the gas released is one which will not degrade labile components of the product.
