A foam dispensing mechanism () comprises: a top (); a cylindrical wall () extending from a peripheral edge of the top; a piston member () arranged within the cylindrical wall; a dispense head () axially displaceable with respect to the top; a resilient bias member () for biasing the dispense head. The piston member has a first opening () and a coupling cylinder () arranged coaxially around said first opening. The dispense head has a cylindrical seal member () positionally fixed with respect to the dispense head (), the seal member () having a first passage opening () with a valve seat (), wherein the seal member's lower portion () is sealingly and axially slidably coupled to the coupling cylinder. An axially displaceable valve member () for blocking or releasing said first passage opening has a valve stem () having its end () coupled to the piston member.

Foam dispenser

The invention relates to a dispenser unit particularly suitable for a liquid container, including an air pump with an air cylinder and an air piston axially displaceable in the air cylinder, an air space defined between the air cylinder and the air piston, supply-closing structure for closing the air supply to the air pump, discharge-closing structure for closing the air discharge from the air pump, an axially displaceable activating element for activating the air pump, and an air inlet opening in the activating element, wherein the air inlet opening debouches in the air space, and at least a part of the air piston forms the supply-closing structure.

Dispenser unit with improved air supply

The invention relates to a system of bellows and co-acting part, including a co-acting part which comprises a stiff outer wall, and a bellows co-acting therewith which comprises a flexible wall of a predetermined shape and thickness, wherein the flexible wall of the bellows is movable along the stiff outer wall of the co-acting part, wherein the bellows includes at least two separately deformable flexible wall parts' which each co-act with a different part of the stiff outer wall of the co-acting part.

System of diaphragm and co-acting part

The invention relates to a dispensing unit, particularly suitable for a liquid container, comprising an air pump with an air cylinder and an air piston (), wherein an air chamber () is defined between the air cylinder and the air piston, a liquid pump with a liquid cylinder and a liquid piston (), wherein a liquid chamber () is defined between the liquid cylinder and the liquid piston. An axially displaceable activating element () for activating the pumps, and upper edge () of air piston () for closing air supply to the air pump, and an oblique wall () of activating element () for closing air discharge from the air pump. The air piston and the liquid piston are movable in axial direction relative to the activating element in order to close air supply to the air pump and close air discharge from the air pump.

Dispenser with improved supply-closing means

The invention relates to a dispenser, particularly suitable for a liquid container, comprising: an air pump with an air cylinder () and an air piston () axially displaceable in the air cylinder, an air space () defined between the air cylinder and the air piston, supply-closing means () for closing the air supply to the air pump, discharge-closing means for closing the air discharge from the air pump, a cover () connected to the air piston, an air inlet opening () in the cover, wherein the air inlet opening debouches directly into the air space, and an annular element () which extends axially on the inside of the cover and which comprises an edge part, which edge part is in contact with at least the part of the inner wall of the cover located around the air inlet opening ().

A dispenser, particularly suitable for a liquid container, comprising a liquid pump provided with an inlet having an inlet valve and an outlet having an outlet valve, an air pump provided with an inlet having an inlet valve and an outlet having an outlet valve, a mixing chamber which is in communication with the outlet of each pump, and a dispensing part provided with an outflow channel with an outflow opening, wherein the outflow channel is in communication with the mixing chamber, and wherein the outlet valve of the air pump is arranged adjacent to the outlet of the liquid pump.

Dispenser for concentrated injection

A foam-forming unit is disclosed. The foam-forming unit includes a mixing chamber communicating with the outlet of a pump for the purpose of mixing liquid and air, and includes a dispensing part provided with an outflow channel with a foam opening for dispensing foam, wherein the outflow channel is in communication with the mixing chamber. Further, a first foam-forming element is included, arranged in the outflow channel such that the foam flowing through the outflow channel passes through the foam-forming element at least twice. The dispensing part is further provided with a spout element in which is located the final part of the outflow channel and the foam opening. Finally, the outflow channel includes a cavity after the first passage through the first foam-forming element, which cavity lies before the spout element as seen in flow direction.

Foam forming unit

Dispensing head

A foam forming unit particularly suitable for a liquid container, comprising a pump for liquid and a pump for air, which are each provided with an inlet and an outlet, the foam forming unit further comprising a mixing chamber which is in communication with the outlet of each pump, a dispensing part provided with an outflow channel with a foam opening, the channel being in communication with the mixing chamber, and valves in respectively the inlet and the outlet of each pump for drawing in respectively delivering air and liquid, wherein one or more valves are formed integrally with the air pump or liquid pump into a single construction element.
