Description

[Technical Field]

[0001] The present invention relates to a dropper container, and more particularly to a dropper container with a residual quantity prevention function that allows the dropper tube to be used conveniently without shaking and can be stably stored in the container body without tilting to either side. [Background technology]

[0002] Cosmetics are articles used on the human body to cleanse, beautify, and attractively enhance the appearance, or to maintain or improve the health of the skin or hair.

[0003] Such cosmetics are broadly classified into basic cosmetics, functional cosmetics, and color cosmetics depending on the purpose of use.

[0004] Functional cosmetics refer to cosmetics that are used to help whiten the skin or improve skin wrinkles or protect the skin from ultraviolet rays.

[0005] However, since most of the functional cosmetics are very expensive, it is economical to use them by precisely delivering a fixed amount of cosmetic contents to the area to be applied. When applying cosmetic contents to the palm of the hand as in the past, a large amount of cosmetic contents is absorbed into the palm, which has the disadvantage of wasting expensive cosmetic contents.

[0006] Furthermore, because the functional cosmetics do not contain preservatives, the contents of the cosmetic are highly susceptible to contamination. If the contents are applied by patting the container with the hands, as with regular cream-type cosmetics, or by placing the container opening against the palm of the hand to expel the contents, as with lotions, contaminants on the hands will seep into the body of the cosmetic container, which could cause the contents of the cosmetic to deteriorate.

[0007] Therefore, when using functional cosmetics, it is desirable to use a fixed amount, and using too much or too little can cause side effects on the skin or even be ineffective, so there is a need for cosmetic containers that can extract the contents in a fixed amount.

[0008] To solve this problem, dropper-type cosmetic containers have been developed and are becoming popular, allowing users to suck up the contents of the cosmetic product into the dropper and then apply it by discharging it onto the skin where the cosmetic product is to be applied.

[0009] However, the conventional dropper-type cosmetic container has the inconvenience of requiring a user to open the container lid and press a button to suck in the cosmetic contents every time they use the cosmetic contents. Also, the amount of cosmetic contents sucked in through the dropper tube varies depending on how hard the user presses the button, making it difficult to dispense a consistent amount each time.

[0010] In order to solve these problems, the applicant filed and registered an "automatic dropper container" under Korean Utility Model Registration No. 20-0480441. The conventional automatic dropper container includes a container body in which the contents are stored, a lid connected to the opening of the container body and consisting of an inner cap and an outer cap, a push pocket that is partially inserted inside the lid and partially protrudes upward, a push tube that is connected to the push pocket and is connected to the inside of the lid and the push pocket so that it can move up and down, an elastic member attached to the outside of the push tube, and a dropper tube that is connected to the push tube and draws in and discharges the contents stored in the container body.

[0011] However, in the prior art, the end of the dropper tube is separated from the bottom of the container body, and after most of the contents stored inside the container body are used, some of the contents remain at the bottom of the container body. In order to use the contents, the user must incline the container body to one side and try to suck the contents into the dropper tube, which is inconvenient. Despite this attempt, some of the contents remain inside, resulting in waste.

[0012] In order to solve this problem, the applicant filed Korean Patent Publication No. 10-2023-0001196 for a "dropper container with residual quantity prevention." The prior art comprises a container body in which contents are stored and which has an inlet formed therein, and a dropper part for aspirating and discharging the contents stored in the container body. The dropper part includes an inner cap fastened to the container body, an outer cap attached to the outside of the inner cap, a dropper tube connector made of an elastic material fixedly attached between the inner cap and the outer cap, a dropper tube connected to one side of the dropper tube connector and having an aspirating and discharging port at its end, and a push button attached to the dropper tube connector and for aspirating or discharging the contents by applying pressure.

[0013] However, in the conventional technology, the dropper tube connector that elastically supports the dropper tube is formed into a smooth curved surface along the inner cap. As a result, after separating the dropper part from the container body, when applying the contents by placing the dropper tube against the skin, the dropper tube shakes, making it inconvenient to use.

[0014] Furthermore, in the conventional technology, when the dropper tube is inserted into the inside of the container body and the container body and the dropper tube are screwed together, the dropper tube rotates and comes into contact with the inside bottom surface of the solution base. During this process of fastening the container body and the dropper part, the dropper tube tilts to one side, causing it to stick tightly to the bottom surface of the container body and resulting in unstable storage.

[0015] [Patent Document 1] Korean Registered Utility Model No. 20-0480441 (Announced on May 26, 2016) [Patent Document 2] Korean Patent Publication No. 10-2023-0001196 (Published on January 4, 2023) Summary of the Invention [Problem to be solved by the invention]

[0016] In order to solve the above problems, the present invention aims to provide a dropper container with a function to prevent residual content from remaining, which is convenient to use by minimizing the shaking of the dropper tube when applying cosmetic contents using the dropper part, by forming a bent structure in a certain section of a dropper tube connector that elastically supports the dropper tube.

[0017] Another object of the present invention is to provide a dropper container that prevents residual volume from being left behind, in which the end of the dropper tube is attached to the center of the bottom surface of the container body, and the dropper part moves up and down around the dropper tube as an axis by rotating the outer cap, so that the dropper tube does not tilt to either side and can be stored stably within the container body. [Means for solving the problem]

[0018] In order to achieve the above object, the present invention provides a dropper container that prevents residual content, which includes a container body that contains cosmetic contents and a dropper portion for suctioning and discharging the cosmetic contents contained in the container body, and the dropper portion includes: (1) an inner cap that is fastened to the container body; (2) an outer cap that is rotatably connected to the outside of the inner cap; (3) an elevating member that is connected between the inner cap and the outer cap and moves up and down; (4) a push button that is fixedly connected to the elevating member and sucks in or discharges the cosmetic contents by applying pressure; (5) a dropper tube that is connected to the internal space of the push button and has a suction and discharge port formed at its end; (6) a guide member that is fixedly connected to the elevating member and guides the linear movement of the dropper tube; and (7) a dropper tube connector made of an elastic material that elastically supports the dropper tube.

[0019] The container body is also characterized in that a dropper tube mounting hole is formed on the bottom surface inside the container body, into which the end of the dropper tube is mounted.

[0020] The inner cap is connected to the outer cap by a connecting member, the connecting member is connected to the inside of the outer cap, and the inner cap is rotatably fitted between the connecting member and the outer cap.

[0021] The inner cap and the lifting member are each formed with a linear guide protrusion and a linear guide hole for coupling with each other, and the outer cap and the lifting member are each formed with a lifting protrusion and a lifting spiral hole for coupling with each other.

[0022] The push button is fitted between the lifting member and the guide member and fixedly coupled thereto, and is characterized in that a pressing portion is formed thereon and presses one surface of the dropper tube connector to fix the dropper tube connector.

[0023] The guide member may have an insertion hole formed therein for inserting the dropper tube connector, and a through hole formed at the center thereof for passing the dropper tube therethrough.

[0024] The dropper tube connector is characterized in that it is formed from a first connecting part that is fixedly connected by being fitted between the push button and the guide member, a second connecting part that is fixedly connected to the dropper tube, and an elastically deforming part that connects between the first connecting part and the second connecting part and elastically deforms or restores its original shape when the container body and the dropper part are attached or detached.

[0025] The elastic deformation portion is characterized by being formed of a first connecting section extending from the first connecting section toward the second connecting section, a second connecting section extending from the second connecting section toward the first connecting section, and a third connecting section connecting the first connecting section and the second connecting section, with both sides facing the first connecting section and the second connecting section, respectively, at a fixed distance apart.

[0026] The dropper tube connector has at least a portion bent, and is expanded by being pushed up into the inner space of the push button by the dropper tube.

[0027] In addition, when the outer cap is rotated relative to the inner cap with the end of the dropper tube in close contact with the bottom surface inside the container body by the dropper tube connector, the lifting member, the push button, the guide member, and the dropper tube connector move vertically back and forth together around the dropper tube as an axis. [Effects of the Invention]

[0028] According to an embodiment of the present invention, the dropper part is detachable from the container body and automatically operates to suck in the contents of the container body or expel the air inside the dropper tube, which is convenient to use, makes it easy to use the contents stored in the container body without leaving any waste, reduces waste of resources, and makes it easy to separate and discharge the contents.

[0029] According to an embodiment of the present invention, a bent structure is formed in a portion of the dropper tube connector that elastically supports the dropper tube, thereby minimizing shaking of the dropper tube when applying cosmetic contents to the skin using the dropper portion, making it convenient to use.

Furthermore, it should be understood that the location or arrangement of individual components in each described embodiment may be changed without departing from the spirit and scope of the invention.

[0033] Accordingly, the following detailed description is not to be taken in a limiting sense, and the scope of the present invention is limited only by the appended claims, along with the full scope of equivalents to which the claims are entitled, so long as they are properly set forth. Like reference numerals in the figures refer to the same or similar functionality across the several aspects.

[0034] The terms used in this invention are selected from currently widely used general terms while taking into consideration the functions of the present invention, but these may change depending on the intentions of engineers in the field, precedents, the emergence of new technologies, etc. In addition, in certain cases, the applicant may arbitrarily select terms, and in such cases, the meanings thereof will be described in detail in the relevant description of the invention. Therefore, the terms used in this invention must be defined based on the meanings of the terms and the overall content of the present invention, rather than simply by their names.

[0035] In the present invention, when a part is said to "comprise" a certain component, this does not mean that it excludes other components, but that it may further include other components, unless otherwise specified.

[0036] Hereinafter, a dropper container for preventing residual quantity according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0037] FIG. 1 is a perspective view of a dropper container according to an embodiment of the present invention, FIG. 2 is an exploded perspective view of a dropper container according to an embodiment of the present invention, FIG. 3 is a cross-sectional view of a dropper container according to an embodiment of the present invention, and FIG. 4 is a cutaway perspective view of a dropper tube connector according to an embodiment of the present invention.

[0038] As shown in the figure, the residual quantity prevention dropper container according to the embodiment of the present invention is composed of a container body (10) and a dropper portion (20), and the dropper portion (20) may be composed of an inner cap (30), an outer cap (40), a lifting member (50), a push button (60), a dropper tube (70), a guide member (80), and a dropper tube connector (90).

[0039] The container body 10 is in the form of a hard cylinder and forms the appearance of a dropper container. Of course, the container body 10 is not limited to a hard cylinder, and can be formed in various shapes and materials taking into consideration the type of contents stored therein, usability, design elements, etc. However, since a dropper tube 70 having a certain length needs to be inserted inside the container body 10, it is appropriate for the container body 10 to be formed narrow in width and relatively long in length.

[0040] The container body 10 contains a liquid or gel cosmetic material in its internal space, and as shown in Figure 2, an inlet 12 is formed on one side of the container body 10, through which the contents are filled and the dropper tube 70 of the dropper 20 can be inserted. A screw thread can be formed on the outer periphery of the inlet 12 of the container body 10 for fastening to the dropper 20.

[0041] Meanwhile, a hollow wiper 14, open at the top and bottom, may be attached to the inside of the inlet 12 of the container body 10. The wiper 14 is in close contact with the outer surface of the dropper tube 70 of the dropper part 20, and when the dropper tube 70 is separated from the container body 10, the wiper 14 scrapes off any cosmetic material adhering to the outer surface of the dropper tube 70, thereby enabling the dropper tube to be used hygienically.

[0042] 3, the wiper 14 is fixedly connected by having its upper peripheral edge attached to the upper end of the inlet 12 of the container body 10 and the remaining portion fitting inside the inlet 12. When fastening the container body 10 and the dropper 20, the dropper tube 70 penetrates into the inside of the wiper 14. In addition, at least a portion of a guide member 80 is inserted inside the wiper 14 to guide the dropper 20 so that it is inserted into the center of the container body 10, thereby allowing the container body 10 and the dropper 20 to be smoothly fastened together.

[0043] A dropper tube mounting hole 16 may be formed in the center of the bottom surface of the container body 10. The dropper tube mounting hole 16 is a hole into which the end of the dropper tube 70 of the dropper part 20 is mounted when the container body 10 and the dropper part 20 are fastened, and limits the swinging of the dropper tube 70. Since the dropper tube mounting hole 16 is formed relatively lower than other parts, the cosmetic contents are transferred into the space inside.

[0044] The dropper part (20) is partially inserted inside the container body (10) and the remaining part is fastened to the top of the container body (10), and the contents stored inside the container body (10) are drawn in and discharged during the process of attaching and detaching the dropper part (20) to the container body (10) or by the user's operation. At this time, the process of fastening and unfastening the dropper part (20) to the container body (10) and the automatic drawing and discharging of the contents by the dropper part (20) are performed continuously.

[0045] 2, the dropper part 20 may include an inner cap 30, an outer cap 40, a lifting member 50, a push button 60, a dropper tube 70, a guide member 80, and a dropper tube connector 90. The detailed configuration of the dropper part 20 will be described below with reference to the drawings.

[0046] The inner cap 30 is detachably fastened to the container body 10. A screw thread is formed on the inner peripheral surface of the inner cap 30, and can be threadedly coupled to the screw thread formed on the inlet 12 of the container body 10. Of course, the container body 10 and the inner cap 30 can be coupled in various ways other than by threading, as long as they are stably and securely coupled to each other and can be easily separated from this state.

[0047] A linear guide protrusion 32 is formed on the outer circumferential surface of the inner cap 30 to guide the linear movement of the lifting member 50, and a mounting protrusion 33 is formed at the end of the linear guide protrusion 32 to protrude outward, so that the end of the lifting member 50 can be mounted. In this case, it is preferable that the linear guide protrusion 32 is formed to extend in the direction of the linear movement of the lifting member 50, and the mounting protrusion 33 is formed to extend along the periphery of the surface of the inner cap 30.

[0048] As shown in Fig. 3, the inner cap 30 is connected to the outer cap 40 by a connecting member 34. The connecting member 34 is fixedly connected to the inside of the outer cap 40, and the inner cap 30 can be rotatably fitted between the connecting member 34 and the outer cap 40. In the dropper container according to the embodiment of the present invention, the inner cap 30 is rotatably connected to the outer cap 40 via the connecting member 34, but this is not limited thereto, and the inner cap 30 may be rotatably connected directly to the outer cap 40 without the connecting member 34.

[0049] The outer cap 40 is configured to function as a handle for using the dropper part 20 or as a rotating body for operating the dropper part 20, and can be rotatably coupled to the inner cap 30 and the lifting member 50 while enclosing them from the outside. The outer cap 40 is in the form of a cylinder with both sides open, and at least a portion of the push button 60 can be exposed on one of the open sides, and a dropper tube 70 can be extended from the opposite side.

[0050] 2, the outer cap 40 has an inner peripheral surface formed with a lifting protrusion 42, which allows the lifting member 50 to move up and down within a certain range. Preferably, a pair of lifting protrusions 42 are formed on the inner peripheral surface of the outer cap 40 so as to face each other, in order to ensure stable up and down movement of the lifting member 50.

[0051] The lifting member 50 is connected between the inner cap 30 and the outer cap 40 so as to be movable in a straight line. A push button 60, a dropper tube 70, a guide member 80, and a dropper tube connector 90 are installed in the inner space of the lifting member 50, and can move up and down together with the outer cap 40 when it rotates relative to the inner cap 30.

[0052] The lifting member 50 has a spiral hole 52 formed on its side surface, which is connected to the outer cap 40 and guides the lifting member 50 as it moves up and down. The lifting protrusions 42 of the outer cap 40 are connected to the spiral hole 52, and the spiral hole 52 may be formed in a spiral shape inclined in any direction along the periphery of the lifting member 50. In this case, it is preferable that a pair of the spiral holes 52 are formed facing each other on the side surface of the lifting member 50, similar to the lifting protrusions 42. A linear guide hole (54) is formed on the side of the lifting member (50) to be connected to the inner cap (30) and to guide the linear movement of the lifting member (50). The linear guide protrusion (32) of the inner cap (30) is connected to the linear guide hole (54) and can be formed to extend in the direction of the linear movement of the lifting member (50).

[0053] Meanwhile, a coupling protrusion 56 is formed at one end of the lifting member 50, so that it can be coupled to a push button 60. The coupling protrusion 56 is preferably formed to protrude inward from the end opposite the lifting spiral hole 52 and the linear guide hole 54, i.e., the portion where the push button 60 is coupled.

[0054] The push button 60 is fixedly connected to the lifting member 50, is exposed to the outside through the open side of the outer cap 40, and is pressed by the user. The push button 60 moves up and down together with the lifting member 50 when the outer cap 40 is rotated relative to the inner cap 30. As the user applies pressure, the internal volume of the push button 60 changes, causing the cosmetic contents contained in the container body 10 to be sucked into the dropper tube 70 or expelled to the outside.

[0055] 3, a coupling hole (recess) 62 is formed on the side of the push button 60, into which the coupling protrusion 56 of the lifting member 50 is fitted, and a pressing portion 64 is formed on one end thereof, which presses one side of the dropper connector 90 to fix the dropper connector 90. At this time, the push button 60 is coupled to the lifting member 50 and is fixed by being fitted between the lifting member 50 and the guide member 80.

[0056] Meanwhile, the push button 60 and the dropper tube connector 90 are made of an elastic material so that they can be easily compressed and restored to their original shape. They are made of a thermosetting resin or a thermoplastic resin. The thermosetting resin is made of one or more of epoxy resin, amino resin, phenol resin, and polyester resin. The thermoplastic resin is preferably made of one or more of polyethylene, acrylic resin, polypropylene, polystyrene, polyvinyl chloride, Teflon, nylon, and polyacetal resin, and is most preferably made of an elastomer-based TPE (Thermo Plastic Elastomer). Of course, the push button 60 and the dropper tube connector 90 are not limited to the above materials and can be made of various materials within a certain range of elasticity.

[0057] The dropper tube (70) is connected to one side of the dropper tube connector (90) and extends downward from the dropper part (20). The dropper tube (70) is configured to suck or discharge the contents of the cosmetic product by changing the internal volume of the push button (60) when the outer cap (40) is rotated or pressed, and its open side is connected to the internal space of the push button (60) and moves up and down together with the lifting member (50) when the outer cap (40) is rotated relative to the inner cap (30).

[0058] An inlet / outlet port 72 is formed at the end of the dropper tube 70, and the cosmetic contents are sucked in or expelled through the inlet / outlet port 72. The dropper tube 70 is tubular with both ends open and the inside is hollow, and may be made of glass so that the inside can be seen, but is not limited thereto, and may be made in various ways taking into consideration the type of cosmetic to be sucked in, usability, durability, design elements, etc.

[0059] As shown in Figure 3, at least a portion of the dropper tube (70) passes through the inlet (12) of the container body (10) and is inserted into the container body (10), and one end of the dropper tube (70), i.e., the outer periphery of the inlet / outlet (72), can contact the bottom surface of the container body (10). The end of the dropper tube (70) is attached by being inserted into the dropper tube attachment hole (16) of the container body (10), and this state is maintained even during the process of attaching / detaching the dropper part (20) to / from the container body (10) and the process of lifting / lowering the lifting member (50) by rotating the outer cap (40). This not only ensures that the cosmetic contents contained in the container body (10) are used without leaving any residue, but also prevents the dropper tube (70) from tilting to one side.

[0060] The guide member 80 is fixedly connected to the lifting member 50 and fixes the dropper tube connector 90 together with the push button 60. The guide member 80 moves up and down together with the lifting member 50 when the outer cap 40 rotates relative to the inner cap 30, and at least a portion of the guide member 80 encloses the outside of the dropper tube 70, guiding the linear movement of the dropper tube 70 as the dropper tube connector 90 elastically deforms or returns to its original shape.

[0061] An insertion hole (82) is formed between the inner and outer walls of the upper part of the guide member (80), and the dropper tube connector (90) is inserted therein. A through-hole (84) is formed in the center, and the dropper tube (70) passes through it. When the container body (10) and the dropper part (20) are fastened together, at least a portion of the guide member (80) can be inserted inside the wiper (14) of the container body (10).

[0062] The syringe tube connector (90) is formed in the inner space of the push button (60) and elastically supports the syringe tube (70), changing the internal volume of the push button (60) as it is elastically deformed or restored by the syringe tube (70).

[0063] As shown in FIG. 4, the dropper tube connector (90) may include a first coupling part (92) that is fixedly coupled as it is fitted between the push button (60) and the guide member (80), a second coupling part (94) that is fixedly coupled to the dropper tube (70), and an elastically deformable part (96) that connects the first coupling part (92) and the second coupling part and that elastically deforms or restores its original shape when the container body (10) and the dropper part (20) are attached or detached.

[0064] The first coupling part (92) is a part that extends at a certain height along the outer periphery of the dropper tube connector (90), one side of which is inserted into the insertion hole (82) of the guide member (80), the other side of which is in close contact with the push button (60), and is fixed by being pressed down by the pressing part (64) of the push button (60). The second coupling part (94) is a part that is formed relatively wide in the center of the dropper tube connector (90), and is coupled to one end of the dropper tube (70) by enclosing it, and has a coupling hole (94a) formed in its center, which connects the internal space of the push button (60) with the open side of the dropper tube (70).

[0065] The elastic deformation portion (96) may comprise a first connecting section (96a) extending in a direction from the first connecting section (92) to the second connecting section (94), a second connecting section (96b) extending in a direction from the second connecting section (94) to the first connecting section (92), and a third connecting section (96c) connecting the first connecting section (96a) and the second connecting section (96b) and facing the first connecting section (92) and the second connecting section (94) at a certain interval. That is, the elastically deformable portion (96) connecting the first connecting portion (92) and the second connecting portion (94) has a bent structure at least in two portions, so that when the dropper portion (20) is separated from the container body (10) and the cosmetic contents are applied to the skin, the dropper portion (20) can be used conveniently while minimizing the shaking of the dropper tube (70) relative to the push button (60) and the guide member (80). When the dropper tube connector (90) is elastically deformed by the dropper tube (70), the bent portion of the elastically deformable portion (96) widens, further expanding the range of deformation and maximizing the utilization of the internal space of the dropper portion (20). Here, the first connecting section (96a) and the second connecting section (96b) of the elastic deformation portion (96) are formed to have different heights and are connected to the third connecting section (96c), and it is preferable that the elastic deformation portion (96) is symmetrical to each other with respect to the center of the third connecting section (96c).

[0066] As described above, the elastic deformation portion (96) of the dropper tube connector (90) connects the first connecting portion (92) and the second connecting portion (94) with at least a portion thereof bent, and when the container body (10) and the dropper portion (20) are connected and the dropper portion (20) is raised and lowered, the elastic deformation portion (96) is pushed up into the inner space of the push button (60) by the dropper tube (70) and is expanded to connect the first connecting portion (92) and the second connecting portion (94) in a straight line, and as the internal volume of the push button (60) changes, the cosmetic contents contained in the container body (10) can be sucked into the dropper tube (70) or the air inside the dropper tube (70) can be expelled to the outside.

[0067] Meanwhile, with the end of the dropper tube (70) in close contact with the bottom surface inside the container body (10) by the dropper tube connector (90), when the outer cap (40) rotates relative to the inner cap (30), the lifting member (50), the push button (60), and the dropper tube (70) can all move up and down a certain distance. That is, as the container body (10) and the dropper portion (20) are fastened together, the dropper tube (70) is installed in the dropper tube installation hole (16) of the container body (10). While maintaining this state, the operation of the dropper portion (20) causes the lifting member (50), the push button (60), the guide member (80), and the dropper tube connector (90) to move vertically back and forth around the dropper tube (70) as an axis without rotating, so that the dropper tube (70) can be stored stably within the container body (10) without tilting to one side.

[0068] 5 to 8 are diagrams illustrating the operating state of the dropper container for preventing residual amount according to the embodiment of the present invention, and the operating process of the dropper container for preventing residual amount according to the embodiment of the present invention will be described with reference to these figures.

[0069] FIG. 5 is a cross-sectional view illustrating how the push button rises when the outer cap is rotated according to an embodiment of the present invention; FIG. 6 is a cross-sectional view illustrating how the container body and the dropper portion are separated according to an embodiment of the present invention; FIG. 7 is a cross-sectional view illustrating how the container body and the dropper are combined according to an embodiment of the present invention; and FIG. 8 is a cross-sectional view illustrating how the push button falls when the outer cap is rotated according to an embodiment of the present invention.

[0070] To use the residual quantity prevention dropper container according to the embodiment of the present invention, the outer cap (40) of the dropper part (20) is rotated to cause the push button (60) to protrude upward from the outer cap (40), which subsequently releases the fastening between the container body (10) and the dropper part (20) and separates the dropper part (20) from the container body (10).

[0071] As shown in Figure 5, when the outer cap (40) is rotated in either direction from the inner cap (30) that is screwed to the container body (10), the lifting projection (42) formed on the outer cap (40) moves within the lifting spiral hole (52) of the lifting member (50). At this time, the linear guide projection (32) of the inner cap (30) is fitted into the linear guide hole (54) of the lifting member (50), so the lifting member (50) does not rotate, but as the lifting projection (42) of the outer cap (40) rotates horizontally, it pushes the lifting member (50) upward, causing it to move linearly upward.

[0072] At the same time, the push button (60), dropper tube (70), guide member (80), and dropper tube connector (90), which are connected to the inside of the lifting member (50), move linearly upward together, causing the push button (60) to protrude above the outer cap (40). As the dropper tube connector (90), which had been elastically deformed by the dropper tube (70), elastically returns to its original shape, the internal volume of the push button (60) increases, and the cosmetic contents inside the container body (10) flow in through the intake / exhaust port (72) of the dropper tube (70). At this time, the dropper tube connector (60) presses the dropper tube (70) toward the bottom of the container body (10) by its elastic restoring force, and the end of the dropper tube (70) remains in close contact with the bottom surface inside the container body (10).

[0073] As shown in Figure 6, when the outer cap (40) continues to rotate, the lifting protrusion (42) of the outer cap (40) is hooked onto the end of the lifting spiral hole (52) of the lifting member (50), and the lifting member (50) and the inner cap (30) are rotated together, thereby releasing the threaded connection between the container body (10) and the inner cap (30).

[0074] Then, after separating the dropper part (20) from the container body (10), the end of the dropper tube (70) is placed on the skin, and the push button (60) is pressed to discharge the cosmetic contents from the dropper tube (70) for use.

[0075] After finishing makeup, the dropper tube (70) of the dropper part (20) is inserted into the inlet part (12) of the container body (10) while the outer cap (40) is rotated in the opposite direction to fasten the container body (10) and the dropper part (20), and then the push button (60) is inserted into the outer cap (40).

[0076] 7, when the outer cap (40) is rotated in the opposite direction, the lifting member (50) and the inner cap (30) rotate together with the outer cap (40), and the container body (10) and the inner cap (30) are screwed together. At this time, the end of the dropper tube (70) is inserted into the dropper tube mounting hole (16) formed in the center of the bottom surface of the container body (10) and mounted thereon.

[0077] As shown in Figure 8, when the outer cap 40 is continuously rotated from the inner cap 30, which is threadedly connected to the container body 10, the lifting projection 42 formed on the outer cap 40 moves within the lifting spiral hole 52 of the lifting member 50. At this time, the linear guide projection 32 of the inner cap 30 is fitted into the linear guide hole 54 of the lifting member 50, so the lifting member 50 does not rotate, and the horizontal rotation of the lifting projection 42 of the outer cap 40 pushes the lifting member 50 downward, causing it to move linearly downward.

[0078] At the same time, push button 60, dropper tube 70, guide member 80, and dropper tube connector 90, which are connected to the inside of lifting member 50, move linearly downward together, inserting push button 60 into outer cap 40. Dropper tube connector 90 is elastically deformed by being unfolded by dropper tube 70 from its bent state, and as the internal volume of push button 60 decreases, air inside dropper tube 70 escapes to the outside through intake / exhaust port 72. At this time, dropper tube connector 90 uses its elastic force to push dropper tube 70 toward the bottom of container body 10, maintaining the end of dropper tube 70 attached to dropper tube attachment hole 16 of container body 10.
