Description

Hand-operated Dropper

The present invention relates to a hand operated dropper.

Due to its convenience, the hand pump is widely used in cosmetic containers that eject liquid contents such as oil and emulsion by a certain amount. In particular, the hand-operated dropper is widely used in cosmetics and pharmaceutical containers due to the fact that the contents can be easily ejected by a certain amount while being stored in a container, and related technologies have been continuously developed.

The structure of the conventional hand operated dropper is such that the structure in which the tubular body is coupled to the elastic button like the structure of the eyedropper is mounted on the upper end of the housing in which the contents are accommodated so as to press the elastic button and release the elastic button, And the structure is such that the contents are sucked into the inside of the tubular body and then ejected from the desired position to the outside of the housing.

However, such a conventional manual type dropper can store only one content in one container. Therefore, there is a problem in that it is practically impossible to store one or more contents simultaneously if necessary or to mix two or more liquids.

Accordingly, in order to solve these problems, various types of manual type droppers have been developed, but there are few manual type droppers that still provide satisfactory results.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems of the prior art and the technical problems required from the past.

That is, an object of the present invention is to provide a hand-operated dropper in which two or more contents are accommodated in a separate space in a container and, if necessary, the contents can be easily mixed and used.

To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described, a manually operated dropper according to the present invention is a manually operated dropper that sucks and ejects a predetermined amount of liquid content by pressing an elastic button,

(a) a housing in which the following powder container is mounted in an inner space which constitutes an appearance of a dropper and whose contents are accommodated;

(b) a housing cap sealing the interior space of the housing from the outside;

(c) a closure fastened to the upper outer surface of the housing through the housing cap, mounting the housing in a container containing the contents and being coupled to the housing cap;

(d) a stem including a horizontal passage communicating with the inner space of the housing and a vertical passage communicating with the horizontal passage, the stem being movable up and down connected to the lower end of the elastic button;

(e) a shaft which is engaged with an outer surface of the stem and moves up and down along the inner surface of the housing cap;

(f) a piston mounted on a lower portion of the stem to open and close the horizontal passage of the stem and move up and down along the inner wall of the housing; And

(g) a compression spring that provides a restoring force to the shaft upon pumping and is positioned between the side projection formed on the upper side of the shaft and the housing cap;

Lt; / RTI >

The powder container has a separate inner space separated from the inner space of the housing and is rotatably mounted.

Therefore, by mixing the powder container in which the separate contents are stored, the powder container can be easily mixed with the contents stored in the housing by rotating the powder container in a state where it is mounted on the housing.

When the elastic button is depressed, the elastic button and the air or the contents inside the tubular body are discharged through the lower end of the tubular body. When the force applied to the elastic button is removed, The elastic button is restored to its original state and the elastic pressure of the elastic button and the tube is lowered so that the liquid content of the housing is introduced into the tube in a predetermined amount.

At this time, the closure is mounted in a structure that surrounds the outer surface of the elastic button, thereby preventing the elastic button from being arbitrarily pressed by an external force, and when the elastic button is pressed or released, So that the contents can be sucked in a fixed amount and can be easily ejected to a desired position. In addition, the unique shape of the closure wrapping the outer surface of the elastic button can provide a sense of aesthetics to the manually operated dropper.

In one specific example, the powder container has a structure in which a discharge hole communicating with the outside is formed to have a predetermined length along an upper outer circumferential surface for discharging the contents from the inner space where the contents are accommodated, Lt; / RTI >

In the above structure, the case body is formed with an outer rib extending laterally from the lower outer circumferential surface, at least one indentation groove is formed in the outer rib, and a protrusion corresponding to the indentation groove is formed in the lower cap And the protrusion may be inserted into the indentation groove to be integrally rotated.

In a specific example, a mounting groove having a shape corresponding to the gasket may be formed on an upper end of the case body along an outer circumferential surface.

In some cases, a guide for guiding the rotation of the powder container may be interposed between the outer surface of the case body and the inner surface of the housing corresponding to the outer surface.

In one specific example, the discharge hole and the through-hole may coincide with each other by rotation of the lower cap, and preferably, the rotation angle of the lower cap may be 180 degrees.

On the other hand, the material of the guide is not particularly limited as long as it is a material capable of improving the sealing ability, and high-density polyethylene (HDPE) having low cost and excellent chemical resistance can be preferably used.

The case body and the cover member may be made of polypropylene (PP), metal, or the like, but the present invention is not limited thereto.

The material of the lower cap is made of ABS resin. The gasket may be formed of a rubber member or silicone. For example, surlyn, polycarbonate, acrylic resin, Metals and the like can be used. Suline is a styrene-acrylonitrile composite resin, which is particularly preferable as a material for a lower cap and a gasket because of its excellent elasticity and chemical resistance.

In one specific example, the combination of the housing and the lower cap can be achieved by, for example, a hook fastening system, so that the contents of the housing can be prevented from leaking to the outside of the dropper and easily opening and closing each other . Therefore, mounting and dismounting of the powder container from the housing can be facilitated.

Further, according to the present invention, the combination of the closure and the housing cap can be achieved by various molding processes as required, and can be achieved by, for example, undercutting.

For the sake of reference, the undercut means a hole, protrusion, or concave portion of a molded product, which means that the molded product can not be pulled out only by movement in the direction in which the injector is opened. Is referred to as an outer undercut.

As described above, since the manual dropper according to the present invention includes the powder container containing the separate contents, it is possible to accommodate two or more contents in a separate space in the container, have
