Eco-Friendly Cosmetic Dropper

The present disclosure relates to a cosmetic dropper and, in more detail, an eco-friendly cosmetic dropper equipped with a detachable pumping cap functioning as a pump, thereby being able to easily separate and remove an elastic member made of a metal-containing material.

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 cosmetic 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 to take out and use a cosmetic preparation every time a 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.

Meanwhile, the importance of eco-friendly materials is becoming increasingly prominent, and soft springs made of eco-friendly materials are being developed to replace metal springs. However, soft springs developed with eco-friendly materials are showing performance degradation issues compared to metal springs.

As a solution for solving this issue, there is a need for an improvement approach that allows for easy separation and discharge because it uses metal springs and can easily extract existing metal springs that cannot be extracted due to a fixed coupling type.

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

The outer stopper protrusionof the outer capmay be formed in a pair with a gap therebetween on the outer wall of the outer cap bodyand can stop the pumping unitat a fixed position by being inserted in a third holeof the pumping unit.

In detail, when the pumping unitis moved down and performs pumping the outer cap stopper operation, protrusionis positioned in the region of a first holeand moved up or down with the pumping unit. Meanwhile, when the pumping unitis rotated in a specific direction, for example, clockwise to stop the pumping unitat a specific position, the outer cap stopper protrusionis inserted into the third holethrough a first holeand a second holeshown in. As a result, the outer cap stopper protrusionis inserted in the third holeand there is almost no space between the third holeand the outer cap stopper protrusion, so the pumping unitcan be positioned at the position.

Meanwhile, in this embodiment, a coupling grooveis formed on the inner wall of the wall body, as shown in, and a coupling protrusionformed at the pumping capcan be detachably locked in the coupling groove. As a result, in this embodiment, it is possible to detachably couple the pumping capto the wall bodyin a locking type, so it is possible to easily separate and remove the elastic member. The detachable structure of the coupling protrusionand the coupling grooveof this embodiment enables separation without excessive force and damage to the wall bodyand the pumping cap, which difference from locking structures for preventing separation of a cap structure from a cosmetic container in the related art. To this end, the outer wall of the coupling protrusionmay have a curved shape and the coupling groovemay also have a curved shape to correspond thereto.

The pumping capof the pumping unit, as shown in, includes: a base bodyhaving a wall portion; a guide postformed on the bottom of the base bodyand inserted and supported between the inner postand the outer post; a piston coupling postformed on the bottom of the base bodyand having the piston memberfitted thereon; and an elevation guide protrusionformed on the outer wall of the base bodyand moving up and down in an elevation guide slotformed at the outer wall post.

In this embodiment, the second threaddescribed above is formed on the wall portionof the base body, so the pumping capcan be detachably thread-fastened to the first threadformed on the wall body.

Further, in this embodiment, the coupling protrusiondescribed above is formed on the wall portionof the base body, so the pumping capcan be detachably locked in the coupling grooveformed on the wall body
