摘要:
A foam pump having a flexible member for engagement with a dispenser, the pump being part of a refill unit including a product reservoir. The flexible connecting member extends from an extreme end of the pump and is received by an actuating carriage that is movably connected to an actuating mechanism. The flexible connecting member permits insertion of the pump into a dispenser, and may act to dampen actuating forces to reduce foam shearing. The flexible connecting member may be provided in the form of a flared tip that is received through an oval opening in the product dispenser, and the pump may include a locking member to prevent unwanted actuation thereof during insertion of the refill unit into the dispenser.

Foam dispensers having integral air compressors with connectors to connect with a disposable refill unit, disposable refill units and liquid pumps are disclosed herein. A refill unit includes a container and a liquid pump. The liquid pump includes a liquid chamber defined at least in part by a liquid inlet valve and a liquid outlet valve. A piston that reciprocates horizontally in the liquid chamber. A mixing chamber is located downstream of the liquid chamber. The mixing chamber is in fluid communication with the liquid chamber and has an air inlet. A sanitary seal is located proximate the air inlet to prevent liquid from contaminating the air compressors.

A foam dispenser is formed by modifying a standard reciprocating piston liquid pump having a reciprocating piston that is pressed to dispense liquid at an outlet. A holding chamber membrane surrounds the reciprocating piston and the outlet to define a holding chamber such that liquid dispensed at the outlet gathers at the bottom of the holding chamber. Pressing on the holding chamber membrane actuates the reciprocating piston liquid pump to dispense liquid into the holding chamber and also forces air and a portion of the liquid gathered in the holding chamber into an through a dispensing spout communicating with the holding chamber. The air and liquid are mixed at a foam media to create a foam product dispensed at an outlet of the dispensing spout.

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.

Foam dispensers, refill units for foam dispensers, and liquid pumps for use in foam dispensers are disclosed herein. In one embodiment, an inverted foam pump includes a compression chamber having an inlet valve and an outlet valve. The compression chamber is in fluid communication with a flow restrictor, an atomizer, a mixing chamber, a foaming chip and an outlet. The inlet valve, outlet valve, flow restrictor, atomizer, mixing chamber, foaming chip and outlet extend along a common axis. An air inlet is included that extends into the mixing chamber; the air inlet is an opening to atmospheric pressure. During operation, the liquid pump is located below the liquid container and liquid flowing from the compression chamber is accelerated and atomized. The atomized liquid enters the mixing chamber at a velocity sufficient to draw in air from the air inlet to mix with the liquid to form a foam.

A locking dispenser to dispense material from a replaceable refill container maintains a lock assembly having a plurality of spring-biased plungers configured in accordance with a predetermined lock parameter. The refill container carries a collar that includes a plurality of markers configured in accordance with a predetermined key parameter. Thus, when a refill container having a key parameter that is compatible with the lock parameter of the key block is installed at the dispenser, the plungers transition from a locked state to an unlocked state to enable the movement of an actuator, which when depressed by a user, results in the dispensement of material from the refill container.
摘要:
A foam dispenser having an actuator and a dispenser housing. The actuator releasably mates with a pomp of a refill unit and is moveable from a first position to a second position. Wherein the second position is further from the refill unit than the first position. Movement of the actuator from the first position to the second position causes the foam dispenser to dispense foam when a refill unit is inserted in the foam dispenser.

A wearable dispenser is provided having an elongate body having a first end and a second end and extending from the first end to the second end in an arc forming at least a portion of an ellipse, oval or circle and extending through greater than 180 degrees so as to fit over a wrist. A product is retained interiorly of the body, and a pump assembly fluidly communicates with the product in the body. The pump assembly includes a movable dispensing tip that, upon reciprocal movement, dispenses a dose of product from the pump assembly and draws another dose of product into the pump assembly.
摘要:
A counter mounted dispensing system includes a bottle support under a counter and a product container having a collar key. The product container is received by the bottle support and held thereby without the need for relative rotational movement between the product container and the bottle support. The product container thus may have a cross-sectional shape that prohibits the product container from being rotated at the location of receipt, typically due to contact between the container and a wall or the sink basin. An alignment skirt on the bottle support ensures that the product container is properly oriented for receipt, and a release ring in the bottle support engages the collar key on the product container to releasably hold the product container.
