Description

  The present invention relates to a manual dropper configured to suck and discharge a predetermined amount of liquid-type contents when an elastic button is pressed, and more particularly, a housing for storing contents, A housing cap that seals the internal space and shuts off from the outside, a tube that sucks the contents from the housing, an elastic button that is sealed and connected to the upper end of the tube, and both sides of the elastic button are exposed to the outside. The present invention relates to a manual dropper including a closing member connected to a housing cap while surrounding the elastic button.

  For convenience, manual pumps are commonly used in cosmetic containers that release a predetermined amount of liquid type contents such as oils and emulsions each time. In particular, the manual dropper is widely used in cosmetic containers and drug containers because it has a characteristic that a predetermined amount of contents can be easily released by the manual dropper every time while the contents are stored in the container.

  Conventional manual droppers are typically constructed in a structure in which an elastic button and tube assembly connected together like a Pasteur pipette is attached to the upper end of a housing containing the contents. When the force applied to the elastic button is released by pressing the elastic button, the content from the housing is sucked into the tube, and the sucked content is discharged from the housing to a desired location.

However, the conventional manual dropper has several problems as follows.
First, an elastic button attached to the upper part of the dropper is exposed to the outside, and as a result, unexpected operation may occur. For example, the drop of the dropper or applying an external force to the dropper may cause the elastic button to be pressed by itself, and as a result, the dropper may operate regardless of the user's intention. A cap may be further attached to the top of the dropper in order to prevent unexpected operation of the dropper. However, it is necessary to remove the cap from the dropper when using the dropper and to attach the cap to the dropper after using the dropper. In addition, the cap can be lost.

  Next, the elastic button is usually made of a flexible material such as silicone or rubber, and the elastic button is formed in a hollow structure whose bottom is opened. The tube is connected to the bottom opening of the elastic button. Therefore, when the elastic button is pressed, the content from the tube is released to the outside, and when the force applied to the elastic button is released, the content is introduced into the tube. However, the amount of the content to be released varies depending on the size of the finger pressing the elastic button, the position of the elastic button to be pressed, and the way the elastic button is pressed. It is difficult to discharge the contents uniformly every time. The above structure is not very suitable for a dropper that contains liquid-type contents such as medicines, essential oils, and aromatic oils and uniformly discharges a predetermined amount of contents.

  Various manual droppers have been developed to solve the above problems. However, there are still no manual droppers that give satisfactory results.

Accordingly, the present invention has been made to solve the above-described problems and other technical problems that have not yet been solved.
Specifically, the object of the present invention is to prevent the elastic button from being arbitrarily pressed due to the dropper dropping or an external force applied to the dropper, and when the elastic button is pressed, a predetermined amount of It is an object to provide a manual dropper that is configured to release contents, thereby improving convenience and reliability.

  In accordance with the present invention, these and other objects are achieved by providing a manual dropper configured to aspirate and discharge a predetermined amount of liquid-type contents upon depression of an elastic button. The manual dropper can be: (a) a housing that forms the appearance of a manual dropper and contains the contents; (b) a housing cap that seals the interior space of the housing and blocks it from the outside; ) A tube connected to an elastic button for sucking the contents from the housing, (d) an airtightly connected to the upper end of the tube, and an elastic button connected to the housing cap; and (e) an elastic button protected from external force. At the same time, it is connected to the housing cap while surrounding the outside of the elastic button so that both sides of the elastic button that sucks a predetermined amount of content are exposed to the outside. Including stop member.

  In the manual dropper having the above-described configuration according to the present invention, when the elastic button is pressed, the elastic button is deformed. At this time, air or contents present in the elastic button and the tube are discharged from the lower end of the tube. On the other hand, when the force applied to the elastic button is released, the elastic button returns to its original state by the elastic force. At this time, the internal pressure of the elastic button and the tube is lowered, and as a result, a predetermined amount of liquid type contents are introduced from the housing into the tube.

  The closing member is connected to the housing cap and surrounds the outside of the elastic button. Therefore, the closing member can prevent the elastic button from being arbitrarily pressed by an external force, and further presses the elastic button. Then, when the force applied to the elastic button is released, it is possible to limit the pressed position and the deformed size of the elastic button. Therefore, it is possible to suck a predetermined amount of contents and discharge the sucked contents to a desired location. In addition, the unique shape of the closure member that surrounds the outside of the elastic button will give the manual dropper a beautiful appearance.

  In a preferred embodiment, the closure member can be formed in an arcuate structure with a vertical cross section. Accordingly, the closing member can prevent the elastic button from being pressed due to the dropper dropping or an unexpected external force applied to the dropper. Furthermore, the closing member has a predetermined strength, and therefore the closing member can minimize damage to the elastic button.

The exposed shape of the closing member is not particularly limited as long as the user can easily press the exposed area of the elastic button with a finger. For example, the closing member may be exposed in an elliptical vertical cross section.
Specifically, both sides of the closing member are smoothly cut into an oval shape so that both sides of the closing member are exposed to the outside. Therefore, the user can easily press the exposed surface of the elastic button with a finger.

The tube is formed in a hollow tube shape that sucks and houses the contents. The tube has a relatively small inner diameter in a region adjacent to the lower end thereof, and can suck the contents efficiently.
In this structure, where the inner diameter of the area adjacent to the lower end of the tube is smaller than the other areas of the tube, when the force applied to the elastic button is released, the introduction speed of the liquid type content increases at the lower end of the tube. Until the elastic button is pressed, the liquid-type contents introduced into the upper end of the tube are prevented from being released to the outside.

  As described above, the tube and the elastic button are connected to each other. This concatenation can be done in the following way. For example, an annular protrusion that extends outward can be provided on the outer periphery of the upper end of the tube, and a connection groove corresponding to the annular protrusion can be provided on the inner peripheral lower portion of the elastic button. This can be done by inserting the annular protrusion of the tube into the connecting groove of the elastic button.

  On the other hand, the connection between the elastic button and the housing cap can be performed in the following manner. For example, a concave groove can be provided on the outer periphery of the lower portion of the elastic button, and a protrusion corresponding to the concave groove can be provided on the inner periphery of the upper portion of the housing cap. When inserted downward into the housing cap, this can be done by engagement of the projection of the housing cap with the concave groove of the elastic button.

The connection between the closure member and the housing cap can be made by various molding methods as required. For example, the connection between the closure member and the housing cap can be made by undercutting.
For reference, the undercut is a part of a molded product such as a hole, protrusion, or recess that cannot be removed depending on the operation performed in the direction in which the injection mold is opened, from the viewpoint of the function or usage of the molded product. Indicates. An undercut formed inside the molded product is referred to as an inner undercut, and an undercut formed outside the molded product is referred to as an outer undercut.

  The connection between the housing and the housing cap is, for example, a screw that can easily engage and disengage the housing and the housing cap and prevent the contents in the housing from being discharged from the dropper. It can be done with a formula structure.

  The closing member may be made of Surlyn, polycarbonate, acrylic resin, or metal having a predetermined strength or elasticity, and the housing cap may be made of polypropylene (PP) or metal. Sarin is a styrene-acrylonitrile compound resin with high elasticity and chemical resistance. Therefore, sarin is particularly suitable for the material of the closure member.

  The foregoing and other objects, features, and other advantages of the present invention will be more clearly understood from the following detailed description when taken in conjunction with the accompanying drawings.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, it should be noted that the scope of the present invention is not limited by the illustrated embodiment.
FIG. 1 is a perspective view typically showing a manual dropper according to an embodiment of the present invention, and FIG. 2 is a perspective view typically showing a structure in which a housing is separated from the manual dropper of FIG.

  Referring to these drawings, the manual dropper 100 is connected to the housing 110 that contains 15 to 20 ml of contents, the housing cap 120 that seals the internal space of the housing 110, and the elastic button 140. A tube 130 that sucks the contents, an elastic button 140 that is hermetically connected to the upper end of the tube 130 and also connected to the housing cap 120, and a closing member that is connected to the housing cap 120 surrounding the elastic button 140 150.

  The housing 110 is a hollow container that contains liquid-type contents. The upper end of the housing 110 is open. The housing cap 120 is connected to the upper end of the housing 110 to seal the internal space of the housing 110 from the outside. The connection between the housing 110 and the housing cap 120 can be made in various ways. For example, a screw thread may be formed outside the upper end protruding portion of the housing 110, and a screw groove corresponding to the screw thread may be formed inside the housing cap 120. In some cases, the housing 110 and the housing cap 120 can be connected to each other in a vertically engaged and disengaged manner, which makes it very easy to connect and disconnect between the housing 110 and the housing cap 120. It can be carried out.

The elastic button 140 is made of highly elastic rubber. The lower end portion of the elastic button 140 and the upper end portion of the tube 130 are connected to each other in a sealed structure.
When a force is applied to the elastic button 140 such that the shape of the elastic button 140 is deformed, the air present in the elastic button 140 and the tube 130 is released from the lower end inlet 132 of the tube 130 as a result. When the force applied to the elastic button 140 is released, the elastic button 140 returns to its original shape by the elastic force. At this time, the internal pressure of the elastic button 140 and the tube 130 decreases, and as a result, a predetermined amount of liquid-type content is introduced from the housing 110 into the tube 130. In this state, the housing 110 is separated from the infusion device 100 as shown in FIG. 2, and then the elastic button 140 is pressed to discharge the contents to a predetermined location.

  The closing member 150 is connected to the housing cap 120 while surrounding the outside of the elastic button 140 so that both sides of the elastic button 140 that sucks a predetermined amount of contents are exposed to the outside while protecting the elastic button 140 from external force. To do.

Referring to FIG. 3, the closing member 150 has an arch-like vertical cross section corresponding to the outside of the elastic button 140. Further, the closing member 150 is cut into an oval 152 so that both surfaces of the elastic button 140 are exposed to the outside. Therefore, the user can easily press the exposed area of the elastic button 140 on both sides with a finger.

FIG. 4 is a vertical sectional view typically illustrating the connection between the elastic button and the tube.
Referring to FIG. 4, the annular protrusion 134 is formed on the outer periphery of the upper end of the tube 130 so that the annular protrusion 134 extends outward, and the connection groove 144 is formed on the inner periphery lower portion of the elastic button 140. The annular protrusion 134 of the tube 130 is inserted into the connection groove 144 of the elastic button 140, thereby achieving connection between the tube 130 and the elastic button 140. That is, when the lower end of the elastic button 140 having elasticity is forcibly expanded and the upper end of the tube 130 is inserted into the elastic button 140 and then the force applied to the elastic button 140 is released, the elastic button 140 is restored. Due to the force, the connecting groove 144 of the elastic button 140 is fitted into the annular protrusion 134 of the tube 130, thereby achieving the connection between the tube 130 and the elastic button 140.

  The tube 130 is adjacent to the lower end of the housing 110 (see FIG. 1) for efficient suction of liquid-type contents and to prevent the contents from being released without pressing the elastic button 140. The region 136 that has a relatively small inner diameter.

FIG. 5 is a front perspective view typically illustrating the manual dropper of FIG.
Referring to FIG. 5, a concave groove 142 is formed on the outer periphery of the lower portion of the elastic button 140, and a protrusion 122 corresponding to the concave groove 142 of the elastic button 140 is formed on the inner periphery of the upper portion of the housing cap 120.
When the elastic button 140 is inserted downward into the housing cap 120, the projection 122 of the housing cap 120 engages the concave groove 142 of the elastic button 140, thereby causing the elastic button 140 and the housing cap 120 to be engaged. The connection between the caps 120 is easily achieved.

Further, an outer undercut 126 is formed laterally at the upper end portion of the housing cap 120, and an inner undercut 156 corresponding to the outer undercut 126 of the housing cap 120 is formed at the lower end portion of the closing member 150. . For this reason, the connection between the housing cap 120 and the closing member 150 is achieved by undercutting.
On the other hand, the housing 110 and the housing cap 120 are connected to each other with a screw-type structure that provides high sealability, so that the contents in the housing 110 are not discharged to the outside.

  As is apparent from the above description, the dropper of the present invention prevents the elastic button from being arbitrarily pressed by an external force, and when the elastic button is pressed, a predetermined amount of content is sucked into the elastic button. When the applied force is released, the suctioned contents are configured to be released, which greatly improves convenience and reliability.
