Soap dispenser
Encyclopedia : S : SO : SOA : Soap dispenser
A soap dispenser is a device that, when manipulated or triggered appropriately, yields soap (usually in small, single-use quantities). It can be manually operated by means of a handle, or can be automatic. Soap dispensers are often found in public restrooms.
Manual soap dispensers
The design of a manual soap dispenser is generally determined by whether the soap comes in liquid, powder, or foam form.
When soap is dispensed in liquid form, its dispenser generally is essentially a pump. The most popular soap dispensers of these type are plastic pump bottles, many of which are disposable.
William Shepphard patented liquid soap on August 22, 1865. Minnetonka Corporation introduced the first modern liquid soap and cornered the market by buying up the entire supply of the plastic pumps needed for the liquid soap dispensers. [link]
Dispensers of powder soaps, such as borax, often take the form of a metal box with a weighted lever; when the lever is pressed, a handful of soap is released.
Finally, manual dispensers of foam soap often consist of a large button which squeezes the foam out of a tube. Many liquid soap dispensers operate in this way as well. A few dispensers operate with a lever that pulls forward and squeezes the soap out.
It has been said that "The handle on a soap dispenser is easily the dirtiest object on the planet, because nobody is expected to wash their hands before using it"
Automatic soap dispensers
An automatic soap dispenser is a hands-free dispenser of soap, but can be used for other liquids such as shampoo and hand lotions. Home dispensers are often battery-powered. The touch-free design operates when a sensor senses motion under the nozzle, and dispenses the liquid. Automatic soap dispensers are becoming increasingly popular in public restrooms around the world.
Ultrasound detecting dispensers for water and "soap" have particular virtues for operating theatres and treatment rooms.
