A dispenser is a device designed to release or distribute a specific amount of a substance or product, often in a controlled and convenient manner. They are commonly used for liquids, such as soap, water, or beverages, but can also be used for items like paper towels or tissues. Dispensers are widely used in both commercial and residential settings to promote hygiene, reduce waste, and increase efficiency. For example, a soap dispenser ensures a controlled amount of soap is dispensed to minimize excess usage, while water dispensers provide easy access to drinking water in offices or public spaces.
