Description

Manual Dropper {Hand-operated Dropper}

The present invention is a manual dropper that inhales and ejects a predetermined amount of liquid contents by pressing an elastic button, and more specifically, a housing in which the contents are accommodated, a housing cap sealing the internal space of the housing from the outside, and housing the contents. It consists of a structure including a tubular body suctioned from the body, an elastic button sealingly coupled to the upper end of the tubular body, and both sides of the elastic button to surround the outer surface of the elastic button, the closure of the structure is coupled to the housing cap It relates to a manual dropper.

Manual pumps have been widely used in cosmetic containers for ejecting a certain amount of liquid contents such as oil and emulsion due to its convenience. In particular, the manual dropper is widely used in cosmetics and pharmaceutical containers due to the feature that the contents can be easily ejected and used in a certain amount while storing the contents in the container, and related technologies have been steadily developed.

In the main configuration of the conventional manual dropper, a structure in which the tubular body is coupled to the elastic button, such as the dropper, is mounted on the upper part of the housing in which the contents are accommodated, thereby pressing the elastic button and releasing the pressure of the elastic button. It is composed of a structure that inhales the contents of the inside of the tube and ejects it to the outside of the housing at a desired position.

However, these conventional manual droppers have some problems.

First, the elastic button mounted on the upper portion of the dropper is exposed to the outside, which may cause unexpected operation. That is, since the elastic button is randomly pressed by the drop or the external force, the dropper operates differently from the intention of the user. In order to prevent unexpected operation of the dropper, a structure may be used in which a cap is additionally mounted on the top of the dropper. However, when the dropper is used, the process of opening and closing the cap is added, which is cumbersome, and there is a problem that a lot of caps are lost.

Second, in general, the elastic button uses a material such as soft silicone, rubber, and has a hollow structure with an open bottom. The open lower body is connected to the tubular body, press the elastic button, the contents of the tubular body is ejected, and when the elastic button is released, the contents flow into the tubular body. However, since the amount of the content is ejected according to the size of the finger pressing the elastic button, the pressing position, the pressing method, etc., there is a problem that it is difficult to constantly eject a predetermined amount during one press. This structure is particularly undesirable in the case of droppers containing liquid contents such as pharmaceuticals, essence oils, aroma oils and the like which must constantly eject a predetermined amount.

In order to solve these problems, manual droppers having various structures have been developed, but there are few manual droppers that still provide satisfactory results.

The present invention aims to solve the problems of the prior art as described above and the technical problems that have been requested from the past.

That is, an object of the present invention is to provide a manual dropper of the improved structure to improve the convenience and reliability by preventing the elastic button is randomly pressed by the drop or external force, and to eject the contents in a certain amount when the elastic button is pressed.

Manual dropper according to the present invention for achieving this object, as a manual dropper to inhale and eject a predetermined amount of liquid contents by pressing the elastic button,

(a) a housing constituting the appearance of the dropper and containing contents;

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

(c) a tubular body which sucks the contents from the housing and is coupled to the following elastic button;

(d) an elastic button sealingly coupled to the top of the tube and coupled to the housing cap; And

(e) a closure of the structure which is coupled to the housing cap and surrounds the outer surface of the elastic button in a shape in which both sides of the elastic button are exposed so as to protect the button from external force and inhale the contents only;

Consists of a structure that includes.

In the manual dropper of the present invention having such a structure, when the elastic button is pressed, the elastic button is deformed while the elastic button and the air or contents inside the tube are discharged through the bottom of the tube, and the elastic button is removed by the elastic force when the force is applied to the elastic button. As the elastic button is restored to its original state, the internal pressure of the elastic button and the tube is lowered, and the liquid contents of the housing are operated in such a manner that a predetermined amount flows into the tube.

At this time, the closure is mounted in a structure surrounding the outer surface of the elastic button, to prevent the elastic button from being arbitrarily pressed by the external force, the pressing position and deformation size of the elastic button when pressing or releasing the elastic button Since it is possible to limit the amount, the contents can be sucked in and ejected to a desired position easily. In addition, the aesthetics can be imparted to the manual dropper by the unique shape of the closure surrounding the outer surface of the elastic button.

In one preferred example, the closure may be of an arcuate structure in a vertical cross section. Therefore, the closure prevents the elastic button from being pressed when the drop or the unexpected external force is applied, and minimizes the breakage of the elastic button by a predetermined strength.

The exposure shape of the closure is not particularly limited as long as the user can easily press the exposed portion of the elastic button with a finger. For example, the closure may have an elliptical shape in a vertical cross section.

Specifically, since both sides of the closure are gently cut into an elliptical shape so that both sides of the elastic button are exposed, the exposed both sides of the elastic button can be easily pressed with a finger.

The tubular body is made of a hollow tubular shape that can receive and accommodate the contents, and a portion near the lower end thereof may have a structure having a relatively small inner diameter for efficient suction of the contents.

In this structure, since the inner portion near the lower end of the tube is formed to have a narrower inner diameter than other portions of the tube, when the elastic button is released, the contents of the liquid flow faster at the lower end of the tube and flow into the upper end of the tube. The contents of the liquid can be prevented from leaking to the outside until the elastic button is pressed.

As mentioned above, the tubular body and the elastic button are mutually coupled, such a coupling structure, for example, the outer circumferential surface of the upper end of the tubular body is formed with an annular projection in the outward direction, the inner circumferential surface of the elastic button below the annular projection The fastening groove corresponding to the formed is formed, the annular protrusion of the tubular body may be made into a structure in which the coupling of the tubular body and the elastic button is achieved by being inserted into the fastening groove of the elastic button.

On the other hand, in the coupling structure of the elastic button and the housing cap, for example, the lower outer peripheral surface of the elastic button is formed with an indentation recessed inwardly, the upper inner peripheral surface of the housing cap protruding portion corresponding to the indentation groove Is formed, the coupling of the elastic button and the housing cap may be made of a structure that is achieved by the elastic button is inserted in the lower direction of the housing cap so that the protrusion of the housing cap is inserted into the indentation groove of the elastic button.

The combination of the closure and the housing cap can be achieved by various forming operations as needed, for example by undercuts.

For reference, an undercut means a hole, a protrusion, or a recess in a molded article function or purpose that cannot be pulled out only by movement in the direction in which the injection machine is opened, that is, an inner undercut, which is located outside the molded article. This is referred to as the outer undercut.

The combination of the housing cap and the housing can be achieved, for example, by a screw method, to prevent the contents of the housing from leaking to the outside of the dropper and to easily open and close each other.

As the material of the closure, surlyn, polycarbonate, acrylic resin, metal, etc., which may provide a predetermined strength or elasticity, may be used, and the material of the housing cap may be polypropylene (PP), metal, or the like. Can be used. Sullin is a styrene-crrylonitrile composite resin, and is particularly preferred as a closure material because of its excellent elasticity and chemical resistance.
