Hand wash bottles are containers designed to hold liquid hand soap or hand sanitizer. They are commonly made of plastic and come in various shapes and sizes, with capacities ranging from a few ounces to several liters.The design of hand wash bottles typically includes a pump or dispenser that allows users to easily dispense the soap or sanitizer onto their hands. The pump or dispenser may be operated by pushing down on the top, twisting a cap, or pulling a lever. Some hand wash bottles also have a mechanism to prevent accidental spills, such as a locking cap or a pump that can be closed when not in use.
