A dropper bottle is a small container designed to hold liquids, typically featuring a narrow neck and a dropper cap. The dropper cap consists of a rubber bulb attached to a glass or plastic tube, allowing precise dispensing of liquid in small amounts. These bottles are commonly used for essential oils, medicines, and other liquid products. Dropper bottles come in various sizes and materials, including glass and plastic. They are popular in the cosmetic, pharmaceutical, and food industries for their ability to deliver accurate doses. The design helps prevent spills and ensures that users can easily control the amount of liquid dispensed.
