A dispensing system includes an above-deck nozzle portion, a reservoir for holding fluid, a foam pump, a multi-lumen dispense passage, and a mixing portion. The above-deck nozzle portion has a dispenser outlet and is disposed above a counter. The foam pump is disposed below the counter and includes at least one liquid pump chamber in fluid communication with the reservoir, at least one air pump chamber, and a pump outlet. The multi-lumen dispense passage includes an inlet, an outlet, at least one liquid lumen, and at least two air lumens. The inlet is in fluid communication with the pump outlet, the outlet is in fluid communication with the dispenser outlet, and the at least one liquid lumen and the at least two air lumens are each in fluid communication with the inlet and the outlet of the multi-lumen dispense passage. The mixing portion is disposed between the multi-lumen dispense passage and the dispenser outlet.

The present invention provides an improved pump assembly incorporating a liquid pump and an air pump and which pump includes a flexible annular diaphragm member coaxially about a piston-forming element forming a component with the liquid pump.

A device comprises a first portion including a first polymer, and a second portion that is relatively flexible in comparison to the first portion and includes a second polymer that is substantially not bondable to the first polymer. A chamber of the device is hermetically sealable with respect to ambient atmosphere and is defined by (i) an interior of the second portion, and/or (ii) a space formed between the first and second portions. A third portion of the device includes a third polymer that is bondable to the first and second polymers and fixedly secures the first and second portions to each other.

A gel foundation container including a pump, the gel foundation container further including content discharge grooves radially formed on a distribution plate; second control protrusions, which are formed inside the content discharge grooves, for controlling the flow of content; a discharge plate formed at the upper end of the distribution plate; and content discharge holes radially formed at the discharge plate at the same position as the content discharge grooves of the distribution plate, wherein the content discharge holes are formed so as to gradually become larger outwardly from the center of the discharge plate, and thus gel foundation is equally discharged in the same amount onto the entire discharge plate when being pumped.

An orientation independent delivery device. The delivery device includes a gas chamber, a delivery chamber, a gas cell, and a delivery aperture. The gas chamber includes a gas-side rigid portion and a gas-side flexible barrier. The gas-side flexible barrier is sealed to the gas-side rigid portion. The delivery chamber includes a delivery-side rigid portion and a delivery-side flexible barrier. The delivery-side flexible barrier is sealed to the delivery-side rigid portion and is oriented adjacent to the gas-side flexible barrier. The gas cell is coupled to the gas-side rigid portion of the gas chamber. The gas cell increases a gas pressure within the gas chamber to expand the gas-side flexible barrier. Expansion of the gas-side flexible barrier applies a compressive force to the delivery-side flexible barrier allowing a delivery material to escape from the delivery chamber.

A pump is configured to operate due to the bending of the pump. The pump can be used in a variety of applications including a dispensing application in which the pump is housed within a pouch. This type of pump takes advantage of the inherent flexible nature of the pouch.

A multiple dose syringe has a first valve defining a first valve opening pressure and a second valve defining a second valve opening pressure. A storage chamber in fluid communication with the second valve stores multiple doses of a substance therein and includes an outlet for dispensing multiple doses of the stored substance therethrough. A compression surface is movable between first and second positions and defines a compression chamber between the compression surface and the first valve. Movement of the compression surface in a direction from the first position toward the second position dispenses substance in the compression chamber through the first valve and out of the syringe. Movement of the compression surface in a direction from the second position toward the first position causes substance to flow from the storage chamber through the second valve and into the compression chamber.

The invention relates to a novel pump device for a fluid container for dispensing a fluid, which device has an operating element and a head part, wherein a piston-cylinder unit forming a pump chamber is provided between the operating element and the head part. An inlet valve is provided at the inlet of the pump chamber, and an outlet valve is provided at the outlet of the pump chamber, wherein the operating element has an outflow with an outflow opening. The outlet valve is also provided at the outflow, and the outflow opening forms a valve seat in such a way that the outlet valve closes the outlet opening from outside.

A dispenser for liquid to pasty substances, has a pumping chamber that has a top pumping chamber wall and a bottom pumping chamber wall in relation to a vertical pumping movement; the bottom and top pumping chamber walls extend from laterally inside to laterally outside in relation to a geometrical axis running vertically through the center of the pumping chamber. In order to advantageously improve a dispenser of the aforementioned type, the bottom pumping chamber wall is joined to the top pumping chamber wall by designing the two walls as a single piece, or by welding or gluing the two walls together, and when the dispenser is actuated, the bottom pumping chamber wall deforms by folding inward such that an elevated region is formed inside in the lateral direction and a lowered region is formed outside in the lateral direction in order for substance to be dispensed.

A multiple dose syringe has a first valve defining a first valve opening pressure and a second valve defining a second valve opening pressure. A storage chamber in fluid communication with the second valve stores multiple doses of a substance therein and includes an outlet for dispensing multiple doses of the stored substance therethrough. A compression surface is movable between first and second positions and defines a compression chamber between the compression surface and the first valve. Movement of the compression surface in a direction from the first position toward the second position dispenses substance in the compression chamber through the first valve and out of the syringe. Movement of the compression surface in a direction from the second position toward the first position causes substance to flow from the storage chamber through the second valve and into the compression chamber.
