Abstract:
A foam assembly connectable to a liquid container includes a main pump body, a resiliently deformable piston dome, an air chamber, a liquid chamber, a mixing zone and a porous member. The main pump body has an exit nozzle with the porous member therein. The air chamber and the liquid chamber are each defined by the piston dome and the main pump body. The liquid chamber has a liquid inlet valve and a liquid outlet valve. The mixing zone is in flow communication with the air chamber and the liquid chamber. The volume of the air chamber and the liquid chamber are each dependent on the position of piston dome and during an activation stroke the piston moves from the at rest position to the depressed position and responsively the volume of the air chamber and the volume of the liquid chamber are reduced.
Abstract:
One aspect of the invention provides a component 112, 165 for a fluid dispenser 110 which defines a dosing chamber 120 for a piston member 114 to stroke in and has an end 160 adapted for engaging a fluid outlet 152 of the fluid dispenser or a seal 154 which overlies the fluid outlet 152 to selectively close and open the fluid outlet 152 or seal 154. Other aspects are disclosed herein.
Abstract:
What is being proposed is a dispensing device for a preferably cosmetic liquid and a manufacturing method. A first material is pretreated in areas through the application of a coating or embossing foil such that a second material which is injection-molded directly against it does not bond with the first material in the pretreated area but rather can be detached again.

Abstract:
A foam dispenser includes a foam pump communicating with the contents of a container holding a foamable liquid. The foam pump includes a pump body, a passage extending through the pump body from an inlet to an outlet, an inlet valve including an inlet flow regulator, and an outlet valve including an outlet flow regulator. The inlet receives foamable liquid from the container. The inlet valve and outlet valve are positioned in the passage to define (a) an inlet stage, (b) an outlet stage, and (c) a transition stage. A liquid port extends through the pump body and communicates with the transition stage, and an air port extends through the pump body and communicates with the outlet stage. A liquid bellows surrounds the liquid port and an air bellows surrounds the air port. The liquid bellows contains the foamable liquid and is movable between an expanded volume and a contracted volume, and expels at least a portion of the foamable liquid to the passage through the liquid port when moved from its expanded volume to its contracted volume. The air bellows contains air and is movable between an expanded volume and a contracted volume, and expels at least a portion of the air to the passage through the air port when moved from its expanded volume to its contracted volume.
Abstract:
A dispensing device comprising an enclosure and a pump, in which the enclosure comprises a base and a cover, in which the cover is attached to the base with a hinge and is rotatable about said hinge towards and away from said base, in which the pump comprises an operating plunger, in which the cover is connected to said plunger by a pivoting linkage adapted to convert the rotational movement of the cover into a linear movement of the operating plunger.
Abstract:
A container (1) with a portion dispensing device for dispensing portions of a product from the container. The container has a main reservoir (2) for storage of product. The portion dispensing device comprises a variable volume product chamber (30) and associated restoring means. The variable volume product chamber (30) has a product outlet and an outlet valve (45). The product chamber also has a product inlet in communication with the main reservoir (2) and an inlet valve. The variable volume product chamber (30) has a volume that is reduced upon increased pressurization of product in the main reservoir (2) of the container (1), and that is increased, at when the increased pressurization of product in the main reservoir (2) of the container (1) is removed. The inlet valve (60) closes the product inlet upon increase of pressurization of the product in the main reservoir (2) so that product passes from the chamber via the product outlet. The inlet valve (60) opens the product inlet upon removal of said increased pressurization.
Abstract:
A pump assembly in the context of a piston pump having a piston carrying a disk which extends radially outwardly to engage a wall of a chamber to substantially prevent fluid flow in one direction and yet permit deflection of the disk away from the wall of the chamber to permit flow in the other direction; the improvement in which two or more of similar such disks are provided spaced axially adjacent one another.
Abstract:
A manually actuated pump type fluid dispenser has a casing (118) defining an internal cavity and a pump member (101) at least partly located in the cavity. The pump member has a central core (101)a and first and second seal members (101b, 101c) projecting radially outwardly of the core and spaced in an axial direction of the core for contact with the casing to define a pump chamber within the cavity. A region (112) of the core between the first and second seal members is resiliently deformable from an initial resiliently biased configuration in which the first and second seal members are axially spaced by a first amount and an axially compressed configuration in which the seal members are spaced by a second amount which is less than the first amount to reduce the volume of the pump chamber.
Abstract:
A dispenser has a body with a variable-volume storage chamber for storing substance, and a dispensing portion defining a dosage chamber in fluid communication with the storage chamber. A first valve includes a valve seat and a flexible valve cover seated thereon defining a normally-closed fluid-tight seam therebetween. The valve cover relative to moves from the valve seat to allow substance through the seam and out of the dispenser. A second valve allows substance from the storage chamber into the dosage chamber and substantially prevents flow from the dosage chamber into the storage chamber. An actuator is manually movable between (i) a first non-actuated position, and (ii) a second actuated position extending into the dosage chamber for compressing a dose of substance therein, dispensing substance through the first valve. The elasticity of the actuator causes it to return to the first non-actuated position upon manually releasing the actuator.
