A soap dispenser is a device used to hold and dispense liquid soap. They are commonly found in public restrooms, kitchens, and homes, providing a convenient way to wash hands and maintain hygiene. Soap dispensers can be manual, requiring a push or pull to release soap, or automatic, using sensors to dispense soap without physical contact. These dispensers come in various designs and materials, including plastic, stainless steel, and glass. Some are refillable, while others use pre-filled soap cartridges. Many soap dispensers are designed to minimize waste and promote cleanliness, making them essential in both commercial and residential settings.
