A method of filling a fluid dispenser is provided and a method for operating power driven pump in a dispenser is provided.

A method of filling a fluid dispenser is provided and a method for operating power driven pump in a dispenser is provided.

A liquid supply system for supplying liquid to one or more liquid dispensers is provided. The system comprises a water source for supply of water to the system; a concentrate reservoir for supply of concentrate to the system; and a liquid reservoir coupled to the water source and the concentrate reservoir, and configured to be coupled to one or more liquid dispensers. In use, the liquid reservoir is configured to supply liquid to the or each dispenser and is replenished via the water source and concentrate reservoir.

Exemplary soap, sanitizer and lotion dispensers are disclosed herein. An exemplary dispenser includes a housing; a receptacle for receiving a container; a container of fluid comprising soap, sanitizer or lotion; a pump in fluid communication with the container; a power source; a pump coupled to a motor and pulse width modulation circuitry in circuit communication with the power source and the motor. The pulse width modulation circuitry is initially set to cause a selected dose of fluid to be dispensed at a base speed. A sensor for detecting a parameter indicative of an actual speed of a dispense of the fluid is also included. When the actual speed of the dispense of fluid is less than the base speed or greater than the base speed, the pulse width modulation circuitry adjusts the pulse width to cause the speed of a following dispense of fluid to be closer to the base speed.

A discharging container comprising a container body that stores a content and a discharging component that discharges the content. The discharging component comprises a cover portion mounted to a mouth neck portion of the container body and a pump head portion that discharges the content by a pressing operation. A tubular guide rod is erected upwards from the periphery of an opening formed in the central portion of a top plate of the cover portion. The pump head portion is provided with an inner waterproof wall capable of moving up and down along the outer peripheral surface of the guide rod, and a first outer waterproof wall located at the outer side of the inner waterproof wall. The discharging container is easy to be manufactured and can reliably prevent water intrusion.

The method includes the introduction of foam into a shower cubicle, a vapor bath, or another sanitary facility. The foam is introduced at a temperature of −15° C. to 20° C., preferably of 0° C. to 18° C., particularly preferred of 5° C. to 15° C., from a foam generator into the shower cubicle, the vapor bath, or the other sanitary facility. The foam preferably has the temperature at an outlet of the foam generator. Apart from that, the disclosure also relates to a device for such a method according to the disclosure and a shower cubicle or a vapor bath having such a device.
