Abstract:
An ecological automatic dropper according to an embodiment of the present invention comprises a container for receiving liquid contents and a lid for opening or closing an inlet of the container. The lid comprises: a screw cap screw-coupled to an inlet part of a container; a spuit tube, which is a discharge path of liquid contents inside the container; a cylinder made of a high elastic material for applying a pressure for filling the spuit tube with the contents or discharging the contents to the outside thereof; a button for contracting or restoring the cylinder; and a cover cooperating with screw-coupling of the screw cap and lifting/lowering of the button. An ecological automatic dropper according to an embodiment of the present invention enables a cylinder to be contracted or restored through lifting/lowering of a button to fill or discharge quantitative liquid contents, and uses the cylinder made of an elastic material without a spring made of a metal material. Therefore, the present invention can provide an easily reusable and eco-friendly automatic dropper.
