The present application claims priority to Korean Patent Applications No. 10-2022-0153946, filed Nov. 16, 2022 the entire contents of which are incorporated herein for all purposes by this reference.

BACKGROUND

Technical Field

The present disclosure relates to a cosmetic dropper and, in more detail, a cosmetic dropper that can improve the durability of a dome-shaped pumping structure and can secure stable pumping.

Description of the Related Art

In general, as a method of using a liquid-state cosmetic preparation such as cosmetics that it is preferable to use by a small amount and an accurate amount at a time including eye cream, a method of individually packaging preparations in capsules, etc., by the amount to be used at each time of use has been used in the related art.

However, such an individual packaging method has a problem of inefficiency because even after a user uses a preparation, a relatively large amount of cosmetic preparation remains in a capsule.

In order to overcome the problem of such an individual packaging method, a configuration designed for a user to take out and use a cosmetic preparation every time the user uses the preparation using a taking-out instrument such as a common pipette or syringe or a taking-out instrument having the configuration of a push pump after the preparation is put into a container has been disclosed.

The above description is the background for helping understand the present disclosure and does not means the related art well known in the art.

SUMMARY

Accordingly, an objective of the present disclosure is to provide a cosmetic dropper that can improve the durability of a dome-shaped pumping structure and can secure stable pumping.

According to an aspect of the present disclosure, there may be provided a cosmetic dropper that includes: a cap unit including an inner cap coupled to a container main body and an outer cap coupled to the inner cap; and a pumping unit coupled to the cap unit and configured to suction liquid makeup stored in a container body into a pipette member connected to the cap unit or discharge liquid makeup suctioned in the pipette member, wherein the pumping unit includes: an elastic pumping part supported by the inner cap and providing a pumping force for suctioning or discharging the liquid makeup; a fixing coupling part detachably coupled to the inner cap and configured to fix the elastic pumping part to the inner cap; and a pusher having a first side coupled to the elastic pumping part and a second side supported to move up and down by the outer cap and pressing the elastic pumping part.

The elastic pumping part may include: a pumping body detachably coupled to the inner by the fixing coupling part and configured to provide a pumping force for suctioning or discharging the liquid makeup by contracting and expanding by the pusher; and a pumping coupling protrusion formed at the pumping body and coupled to a pressing unit.

The elastic pumping part may further include a pumping flange formed at the pumping body and supported by a supporting post formed at the inner cap by being pressed by the fixing coupling portion.

The pumping coupling protrusion may be detachably fitted in a coupling post formed at the pusher.

The fixing coupling part may include: a base body detachably coupled to an inner cap head of the inner cap; and a pressing body formed at an upper portion of the base body and configured to press a pumping flange formed at the elastic pumping part.

An inner wall of the pressing body may be supported by an outer wall of a pumping body of the elastic pumping part.

The pusher may include: a pushing body disposed over the elastic pumping part; a coupling post formed on a ceiling wall inside the pushing and detachably coupled to the elastic pumping part; and a body step formed on an outer wall of the pushing body and locked and coupled to an outer cap step formed at the outer cap.

Embodiments of the present disclosure can improve the durability of a dome-shaped pumping structure because an elastic pumping part is detachably coupled to an inner cap by a fixing coupling part and a stable coupling structure can be secured by the fixing coupling part.

Further, since the outer wall of the elastic pumping part is supported by the inner wall of the fixing coupling part and the inner wall of the elastic pumping part is supported by a supporting post of the inner cap, pumping can be stably performed.
