Dispensers are devices designed to release a specific amount of a product, such as liquids, powders, or other materials, in a controlled manner. Common examples include soap dispensers, which provide a measured amount of soap for handwashing, and beverage dispensers, which serve drinks in restaurants or events. These devices can be manual or automatic, with automatic dispensers often using sensors to detect when a user is present. Dispensers are widely used in various settings, including homes, offices, and public places, to promote hygiene and convenience while minimizing waste.
