Abstract
A foam dispenser comprises a housing having an opening, a fluid reservoir placed in the opening of the housing, a plug connected to the fluid reservoir in the opening, and a foam pump, comprising an air pump, a fluid pump, a closable supply to the air pump, a nozzle, and a movable operating part, wherein the foam pump dispenses a quantity of foam through the nozzle upon actuation of the operating part in a direction of pumping, wherein the foam pump and the fluid reservoir are combined into a removable storage holder. The foam dispenser comprises a coupling piece connected to the foam pump, with which the removable storage holder is fastened to the housing.
Claims20
A foam dispenser, comprising:
- a housing;
- a fluid reservoir configured for placement in the housing and including an opening;
- a plug connected to the fluid reservoir in communication with the opening so as to permit fluid within the fluid reservoir to be withdrawn from the fluid reservoir;
- a foam pump including:
- an air pump;
- a fluid pump;
- a closable supply to the air pump;
- a nozzle;
- and
- a movable operating part, wherein the foam pump is configured to dispense a quantity of foam through the nozzle upon actuation of the operating part in a direction of pumping;
- and
- a coupling piece including a first side for connection to the foam pump and a second side for connection to the plug to combine the fluid reservoir, the plug, and the foam pump into a storage holder, the coupling piece being configured to removably and rigidly fasten the foam pump of the storage holder to the housing.
A storage holder configured for placement in a foam dispenser, comprising:
- a fluid reservoir having an opening;
- a plug connected to the fluid reservoir in communication with the opening so as to permit fluid within the fluid reservoir to be withdrawn from the fluid reservoir;
- and
- a foam pump, including:
- an air pump;
- a fluid pump;
- a closable supply to the air pump;
- a nozzle;
- and
- a movable operating part, wherein the foam pump dispenses a quantity of foam through the nozzle upon actuation of the operating part in a direction of pumping;
- and
- a coupling piece removably connected to both the foam pump and the plug, and configured to fasten the foam pump to a housing within which the reservoir can be placed.
A coupling assembly, comprising:
- a coupling piece for establishing communication between a foam pump and a reservoir for containing material to be dispensed by the foam pump, the coupling piece including:
- a pump coupling element configured to removably connect to the pump;
- a housing engagement element;
- a reservoir coupling element for connecting to the reservoir;
- and
- a passage extending through the pump coupling element, the housing engagement element, and the reservoir coupling element to enable material from the reservoir to be drawn through out of the reservoir;
- and
- an adapter configured to be rigidly associated with a housing of a fluid dispenser, the adapter including:
- a coupling piece engagement element for receiving and removably coupling to the housing engagement element of the coupling piece.
