Abstract: A storage holder for placement in a liquid or foam dispenser includes a liquid reservoir having an opening and a plug provided in the opening. The storage holder also includes a pump having a pump section and an inlet tube extending from the pump section. The storage holder further includes a spacer having an opening for the inlet tube, with the spacer being positioned between the pump section and the plug so that a defined distance is provided between the pump section and the plug. The spacer is fixed at a position relative to the plug and relative to the pump only by a clamping connection between the inlet tube and the plug. The spacer is not connected to the pump and the spacer is not connected to the plug such that spacer may be separated from the pump and the plug when the pump is pulled out of the plug.

Abstract: A storage holder 1 for placement in a liquid or foam dispenser, comprising a liquid reservoir 2, a pump 3 and a spacer 4. The liquid reservoir 2 has an opening 5 provided with a plug 6. The pump 3 is provided with an inlet tube 9, which inlet tube 9 is fixed into the opening of the plug by a clamping connection. The spacer 4 is provided with an opening for the inlet tube 9 and provided at its exterior with a means 11 to couple the storage holder 1 to the liquid or foam dispenser. The spacer 4 is positioned between the pump 3 and the plug and fixed into position relative to the plug 6 and relative to the pump 3 only by the clamping connection between inlet tube 9 and plug 6.

Abstract: A method of maintaining a fluid dispenser that includes a housing holding an assembly, including a liquid reservoir, a pump for dispensing the fluid product, and an outlet nozzle includes disconnecting the a compressor portion of the pump and substituting the disconnected compressor by a replacement compressor, wherein the replacement compressor has a different pressurizing volume to the replaced compressor.

Abstract: A dispenser includes a housing holding an assembly, including a liquid reservoir, a pump for dispensing the fluid product, and an outlet nozzle. The pump includes a liquid chamber for containing a dose of the liquid product and a pressurizing device which allows liquid product to be drawn into or expelled from the liquid chamber. The dispenser further includes a shunting chamber including a first aperture allowing flow access to the reservoir, a second aperture allowing flow access to the outlet nozzle, and a third aperture allowing flow access to the liquid chamber. The third aperture is disposed off-axis with respect to the first and second apertures. The shunting chamber further includes a mechanically actuated governing device that has two states, one defining a flow path between the first and third apertures and one defining a flow path between the third and second apertures.

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.

Abstract: A dispenser for dispensing a fluid includes a housing, a fluid reservoir placed in the housing, and a pump. The pump includes a nozzle protruding therefrom and an operating part connected to the fluid reservoir. When the operating part is moved from an initial position, in which flow of fluid through the pump from the fluid reservoir to the nozzle is substantially prevented, in a direction of pumping, fluid is pumped from the fluid reservoir to the nozzle. The dispenser also includes a resilient element which, upon movement of the operating part from the initial position, exerts a force opposed to the direction of pumping. The nozzle forms part of the operating part and is at an angle relative to the direction of pumping. The engagement mechanism externally engages an area of a part of the nozzle protruding from the operating part.

Abstract: Rapid connecting assembly for an aerosol can and a dispensing device. The rapid connecting assembly consists of a first part which is to be connected to the aerosol can and is supplied together with the aerosol can. The second part of the rapid connecting assembly is connected to the dispensing device. A tubular holder is present in this second part, for receiving the tubular part projecting from the aerosol can when the dispensing device and the aerosol can are being connected to each other. For simple connection of the two parts, one of the parts is provided with a lug and the other part is provided with a peripheral edge. The peripheral edge is provided with a flattened part for receiving the lug.

Abstract: A dispenser to be fitted on the top of an aerosol can so as to atomize a very small quantity of the contents of the aerosol can at regular intervals automatically. An attachment having an electrically operated valve is secured to the aerosol can. Operation of the valve takes place via a controller which is supplied by power by a photovoltaic or solar panel. In this way, it is ensured that dispensing the desired material takes place only when there is sufficient light striking the solar panel.

Abstract: Dosing unit comprising a dispensing device and a container bag unit. The container bag unit has an imperforate wall. A sleeve-shaped part having an opening therethrough is secured to the wall, the wall closing one end of the sleeve-shaped part. A piercing element with a point is disposed within the sleeve with its point directed toward the wall. A dispensing device is receivable in the end of the sleeve-shaped part opposite the wall to engage the piercing element and to move the piercing element relative to the sleeve to pierce the wall to permit flow of the contents of the bag unit through the sleeve-shaped part and to and through the dispensing device. The piercing element is fixed to the sleeve-shaped part by a rupturable connection that breaks when the dispensing device presses against the piercing element.
