Description

[Technical field]

[0001] One aspect of the present disclosure relates to a dropper container, and more specifically, to a remainder-preventing dropper container capable of conveniently using a dropper tube without shaking and stably storing the dropper tube in a container body without being inclined to any one side.[Background Art]

[0002] Cosmetics refer to articles used in the human body to make the human body clean, add charm, change appearance brightly, or maintain or promote the health of the skin or hair.

[0003] These cosmetics are largely divided into basic cosmetics, functional cosmetics, and color cosmetics according to their purpose of use.

[0004] The functional cosmetics refer to cosmetics used to help skin whitening or to help skin wrinkle improvement and to protect skin from ultraviolet rays.

[0005] However, such functional cosmetics are very expensive in most cases, and thus it is economical to accurately supply a fixed amount of the cosmetics to a portion to which the cosmetic contents are to be applied, and when using the cosmetics by pouring the cosmetic contents onto the palm in the related art, there is a disadvantage in that expensive cosmetic contents are wasted because a large amount of the cosmetic contents are absorbed into the palm.

[0006] In addition, since the functional cosmetics do not use a preservative, the cosmetic contents are very vulnerable to contamination, so that when the cosmetic contents are used by being applied with a hand like a general cream-type cosmetic, or when the cosmetic contents are discharged and used by bringing an opening of the container into contact with the palm, such as a lotion, contaminants in the hand may penetrate into a body of the cosmetic container, there is a concern that the cosmetic contents may deteriorate.

[0007] Accordingly, it is preferable to use a fixed amount of functional cosmetics when using the functional cosmetics, and using too much or too little may cause side effects on the skin or be ineffective, so that there is a need for a cosmetic container capable of extracting contents in a fixed amount.

[0008] In order to solve this problem, a dropper (spuit)-type cosmetic container has been developed and distributed, in which a user may suck cosmetic contents using the dropper-type cosmetic container and discharge and apply the cosmetics to a skin area to which the cosmetic contents are to be applied.

[0009] However, the conventional dropper-type cosmetic container is inconvenient in that the user has to use the cosmetic contents by pressing the button and suck the cosmetic contents after opening a container cap every time the cosmetic contents are used, and there is also a problem in that it is difficult to discharge a fixed amount of cosmetic contents every time the cosmetic contents are used because the amount of the cosmetic contents sucked through the dropper tube varies every time the user presses the button.

[0010] In order to solve the problem, the present applicant has filed and registered Korean Registered Utility Model No. 20-0480441 entitled "Automatic dropper container", in which the conventional automatic dropper container includes a container body in which contents are accommodated, a lid coupled to an opening of the container body and including an inner cap and an outer cap, a pressing pocket having a portion inserted into the lid and the other portion protrudes upward of the lid, a push tube coupled to the pressing pocket and coupled to the lid and an inner side of the pressing pocket so as to be vertically movable, an elastic member mounted on an outer side of the push tube, and a dropper tube coupled to the push tube so as to suck and discharge the contents accommodated in the container body.

[0011] However, according to the related art, since an end part of the dropper tube is spaced apart from an inner bottom surface of the container body, after most of the contents accommodated in the container body are used, the contents remain on the bottom portion of the container body, and in order to use the contents, there is an inconvenience in that the container body has to be inclined to any one side and the suction to the dropper tube has to be attempted, and despite such an attempt, some contents remain inside the container body, resulting in waste.

[0012] In order to solve the problem, the present applicant has filed Korean Unexamined Patent Publication No. 10-2023-0001196 entitled "A remainder-preventing dropper container", in which the related art includes a container body in which contents are accommodated and which has an inlet part formed therein, and a dropper part configured to suck and discharge the contents accommodated in the container body, wherein the dropper part includes an inner cap fastened to the container body, an outer cap coupled to an outer side of the inner cap, a dropper tube connector fixedly coupled between the inner cap and the outer cap and formed of an elastic material, a dropper tube connected to one side of the dropper tube connector and having a suction outlet formed at an end part thereof, and a push button coupled to the dropper tube connector to suck or discharge the contents by pressing.

[0013] However, in the related art, the dropper tube connector elastically supporting the dropper tube is formed in a soft curve along the inner cap, and thus, when the dropper tube is attached to the skin after the dropper part is separated from the container body, the dropper tube is shaken and inconvenient to use.

[0014] In addition, the related art has a problem in that, when the dropper tube is screw-coupled to the container body while inserting the dropper tube into the container body, the dropper tube comes into contact with the inner bottom surface of the container body while being rotated, and the dropper tube makes close contact with the bottom surface of the container body while being inclined to any one side during fastening of the container body and the dropper part, resulting in unstable storage of the dropper tube.[Related Art Document][Patent Document]

[0015] (Patent Document 0001) Korean Registered Utility Model No. 20-0480441 (Published on May 26, 2016) (Patent Document 0002) Korean Unexamined Patent Publication No. 10-2023-0001196 (Published on January 4, 2023) [Disclosure][Technical Problem]

[0016] In order to solve the above problems, an object of the present disclosure is to provide a remainder-preventing dropper container capable of conveniently using a dropper tube while minimizing shaking of the dropper tube when cosmetic contents are applied using a dropper part by forming a bent structure in some sections of a dropper tube connector elastically supporting the dropper tube.

[0017] In addition, another object of the present disclosure is to provide a remainder-preventing dropper container capable of stably storing a dropper tube in a container body without being inclined to any one side as a dropper part moves up and down around the dropper tube by rotation of an outer cap in a state where an end part of the dropper tube is seated on a center of a bottom surface of the container body.[Technical Solution]

[0018] To achieve the above objects, one aspect of the present disclosure provides a remainder-preventing dropper container comprising a container body in which cosmetic contents are accommodated, and a dropper part configured to suck and discharge the cosmetic contents accommodated in the container body, in which the dropper part includes: an inner cap fastened to the container body; an outer cap rotatably coupled to an outer side of the inner cap; a vertically movable member coupled between the inner cap and the outer cap to move up and down; a push button fixedly coupled to the vertically movable member and configured to suck or discharge the cosmetic contents by pressing; a dropper tube connected to an internal space of the push button and having a suction outlet formed at an end part of the dropper tube; a guide member fixedly coupled to the vertically movable member to guide a linear movement of the dropper tube; and a dropper tube connector configured to elastically support the dropper tube and formed of an elastic material.

[0019] In addition, the container body may be formed on an inner bottom surface thereof with a dropper tube seating hole on which the end part of the dropper tube is seated.

[0020] In addition, the inner cap may be coupled to the outer cap by a coupling member, in which the coupling member may be coupled to an inner side of the outer cap, and the inner cap may be rotatably fitted between the coupling member and the outer cap.

[0021] In addition, the inner cap and the vertically movable member may be formed with a linear guide protrusion and a linear guide groove, respectively, so that the inner cap and the vertically movable member may be coupled to each other, and the outer cap and the vertically movable member may be formed with a lifting protrusion and a lifting spiral groove, respectively, so that the outer cap and the vertically movable member may be coupled to each other.

[0022] In addition, the push button may be fixedly coupled while being fitted between the vertically movable member and the guide member, and may have a pressing part to fix the dropper tube connector while pushing one surface of the dropper tube connector.

[0023] In addition, the guide member may have an insertion groove so that the dropper tube connector may be inserted into the insertion groove, and may have a through-hole formed at a center of the guide member so that the dropper tube may extend by passing through the through-hole.

[0024] In addition, the dropper tube connector may include a first coupling part fixedly coupled while being fitted between the push button and the guide member, a second coupling part fixedly coupled to the dropper tube, and an elastic deformation part configured to connect the first coupling part and the second coupling part to each other and elastically deformed or restored when the container body is attached to or detached from the dropper part.

[0025] In addition, the elastic deformation part may include a first connection section extending from the first coupling part toward the second coupling part, a second connection section extending from the second coupling part toward the first coupling part, and a third connection section configured to connect the first connection section and the second connection section to each other, in which both side surfaces of the third connection section face each other while being spaced apart from the first coupling part and the second coupling part by a predetermined distance.

[0026] In addition, at least some sections of the dropper tube connector may be bent and unfolded while being pushed up into the internal space of the push button by the dropper tube.

[0027] In addition, the vertically movable member, the push button, the guide member, and the dropper tube connector may be vertically reciprocated together about the dropper tube when the outer cap is rotated with respect to the inner cap in a state where the end part of the dropper tube makes close contact with an inner bottom surface of the container body by the dropper tube connector.[Advantageous Effects]

[0028] According to the embodiment of the present disclosure, the dropper part is automatically operated when the dropper part is attached to or detached from the container body to suck the contents of the container body or to discharge air inside the dropper tube, thereby providing convenience of use, reducing waste of resources because the contents accommodated in the container body may be easily used without any residue, and facilitating separation and recycling.

[0029] According to the embodiment of the present disclosure, the bent structure is formed in some sections of the dropper tube connector elastically supporting the dropper tube, so that the dropper part may be conveniently used while minimizing shaking of the dropper tube when the cosmetic contents are applied to the skin using the dropper part.

[0030] According to the embodiment of the present disclosure, the dropper tube may be stably stored in the container body without being inclined to any one side as the dropper part moves up and down around the dropper tube by rotation of the outer cap in a state where the end part of the dropper tube is seated on the center of the bottom surface of the container body.[Description of Drawings]

[0033] Accordingly, the detailed description described below is not intended to be taken as a restrictive meaning, but if it is properly described, the scope of the present disclosure is restricted only by the appended claims, together with all scopes equivalent to the claims. In the drawings, the similar reference symbols refer to the same or similar functions throughout several aspects.

[0034] The terms used in the present disclosure have been selected from currently widely used general terms in consideration of the functions in the present disclosure. However, the terms may vary according to the intention of one of ordinary skill in the art, case precedents, and the advent of new technologies. Also, for special cases, meanings of the terms selected by the applicant are described in detail in the description section. Accordingly, the terms used in the present disclosure are defined based on their meanings in relation to the contents discussed throughout the specification, not by their simple meanings.

[0035] When a part may "include" a certain constituent element, unless specified otherwise, it may not be construed to exclude another constituent element but may be construed to further include other constituent elements.

[0036] Hereinafter, a reminder-preventing dropper container according to an embodiment of the present disclosure will be described in detail with reference to accompanying drawings.

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

[0038] As illustrated in FIGS. 1 to 4, the remainder-preventing dropper container according to the embodiment of the present disclosure may include a container body 10 and a dropper part 20, in which the dropper part 20 may include an inner cap 30, an outer cap 40, a vertically movable 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 has a rigid cylindrical shape, which forms an appearance of the dropper container. Obviously, the container body 10 is not limited to the rigid cylindrical shape, and may be formed in various shapes or materials in consideration of a type of contents stored therein, usability, or design factors. However, since the dropper tube 70 having a predetermined length needs to be inserted into the container body 10, it is appropriate that the dropper tube has a narrow width and a relatively long length.

[0040] A liquid or gel cosmetic material is accommodated in an internal space of the container body 10, and as illustrated in FIG. 2, an inlet part 12 is formed at one side of the container body 10, and contents are filled through the inlet part 12, and the dropper tube 70 of the dropper part 20 may be inserted into the inlet part 12. A screw thread may be formed on an outer circumference of the inlet part 12 of the container body 10 for fastening with the dropper part 20.

[0041] Meanwhile, a hollow wiper 14 with open upper and lower parts may be coupled to an inner side of the inlet part 12 of the container body 10. The wiper 14 makes close contact with an outer surface of the dropper tube 70 of the dropper part 20 to wipe out the cosmetic material stuck on an outer circumference of the dropper tube 70 when the dropper tube 70 is separated from the container body 10, thereby allowing the dropper tube 70 to be used in a hygienic manner.

[0042] As illustrated in FIG. 3, an upper edge of the wiper 14 is seated on an upper end of the inlet part 12 of the container body 10, and the remaining portion thereof is fixedly coupled while being inserted into the inlet part 12, and the dropper tube 70 extends by passing through an inner side of the wiper 14 when the container body 10 is fastened to the dropper part 20. In addition, as at least a portion of the guide member 80 is inserted into the wiper 14 to guide a direction of the dropper part 20 such that the dropper part 20 is inserted into the center of the container body 10, the container body 10 may be smoothly fastened to the dropper part 20.

[0043] In addition, a dropper tube seating groove 16 may be formed at the center of a bottom surface of the container body 10. The dropper tube seating groove 16, which is a groove on which an end part of the dropper tube 70 of the dropper part 20 is seated when the container body 10 is fastened to the dropper part 20, restricts shaking of the dropper tube 70 and is formed to be relatively lower than other portions so that the cosmetic contents move to an internal space thereof.

[0044] A portion of the dropper part 20 is inserted into the container body 10, and the remaining portion thereof is fastened to an upper part of the container body 10, and the contents accommodated in the container body 10 are sucked and discharged during attachment or detachment of the container body 10 or by a user's operation. In this case, the fastening or unfastening of the container body 10 and the dropper part 20 and the automatic suction or discharge of the contents by the dropper part 20 are continuously performed.

[0045] As illustrated in FIG. 2, the dropper part 20 may include the inner cap 30, the outer cap 40, the vertically movable member 50, the push button 60, the dropper tube 70, the guide member 80, and the dropper tube connector 90. Hereinafter, detailed components of the dropper part 20 will be described in detail with reference to the drawings.

[0046] The inner cap 30 is detachably fastened to the container body 10. A screw thread may be formed on an inner circumferential of the inner cap 30 to be screw-coupled to the screw thread formed on the inner part 12 of the container body 10. Obviously, the container body 10 and the inner cap 30 may have various coupling methods within a range in which the container body 10 and the inner cap 30 may be stably and fixedly coupled to each other and easily separated from each other, in addition to the screw-coupling by the screw thread.

[0047] A linear guide protrusion 32 may be formed on an outer circumference of the inner cap 30 to guide a linear movement of the vertically movable member 50, and a seating protrusion part 33 may protrude outward from an end part of the linear guide protrusion 32 to allow an end part of the vertically movable member 50 to be seated on the seating protrusion part 33. In this case, the linear guide protrusion 32 extends along a linear movement direction of the vertically movable member 50, and it is preferable that the seating protrusion part 33 extends along a circumference of a surface of the inner cap 30.

[0048] As illustrated in FIG. 3, the inner cap 30 is coupled to the outer cap 40 by a coupling member 34. The coupling member 34 may be fixedly coupled to an inner side of the outer cap 40, and the inner cap 30 may be rotatably fitted between the coupling member 34 and the outer cap 40. In the dropper container according to the embodiment of the present disclosure, the inner cap 30 is rotatably coupled to the outer cap 40 by the coupling member 34 as an example, but the present disclosure is not limited thereto, and the inner cap 30 may be directly and rotatably coupled to the outer cap 40 without the coupling member 34.

[0049] The outer cap 40 is a component serving as a handle for using the dropper part 20 or a rotating body for operating the dropper part 20, and may be rotatably coupled while surrounding outer sides of the inner cap 30 and vertically movable member 50. The outer cap 40 has a cylindrical shape with both open sides, in which at least a portion of the push button 60 may be exposed to the open one side, and the dropper tube 70 may extend to the opposite side thereof.

[0050] As illustrated in FIG. 2, a lifting protrusion 42 may be formed on an inner circumference of the outer cap 40 to move the vertically movable member 50 up and down by a predetermined section. In this case, it is preferable that a pair of lifting protrusions 42 protrude to face each other on the inner circumference of the outer cap 40 in order for the vertically movable member 50 to stably move up and down.

[0051] The vertically movable member 50 is coupled between the inner cap 30 and the outer cap 40 to be linearly movable. The push button 60, the dropper tube 70, the guide member 80, and the dropper tube connector 90 are installed in the internal space of the vertically movable member 50, and may move up and down together when the outer cap 40 is rotated with respect to the inner cap 30.

[0052] A lifting spiral groove 52, which is coupled to the outer cap 40 to guide a vertical movement of the vertically movable member 50, is formed on a side surface of the vertically movable member 50, in which the lifting protrusion 42 of the outer cap 40 may be coupled to the lifting spiral groove 52, and the lifting spiral groove 52 may be formed in a spiral shape inclined in any one direction along the circumference of the vertically movable member 50. In this case, it is preferable that a pair of lifting spiral grooves 52 are formed on the side surface of the vertically movable member 50 to face each other, similar to the lifting protrusion 42. In addition, a linear guide groove 54, which is coupled to the inner cap 30 to guide a linear movement of the vertically movable member 50, is formed on the side surface of the vertically movable member 50, in which a linear guide protrusion 32 of the inner cap 30 may be coupled to the linear guide groove 54 and may extend along the linear movement direction of the vertically movable member 50.

[0053] Meanwhile, a coupling protrusion part 56 may be formed on one end part of the vertically movable member 50 to be coupled to the push button 60. It is preferable that the coupling protrusion part 56 protrudes inward from an end part opposite to the lifting spiral groove 52 and the linear guide groove 54, that is, a portion to which the push button 60 is coupled.

[0054] The push button 60 is fixedly coupled to the vertically movable member 50, and is pushed by a user while being exposed through one open side of the outer cap 40. The push button 60 moves up and down together with the vertically movable member 50 when the outer cap 40 is rotated with respect to the inner cap 30, and sucks the cosmetic contents accommodated in the container body 10 into the dropper tube 70 or discharges the cosmetic contents to the outside as an internal volume thereof is changed by pressing of the user.

[0055] As illustrated in FIG. 3, a coupling groove 62 is formed on a side surface of the push button 60 so that the coupling protrusion 56 of the vertically movable member 50 is fitted thereinto, and a pressing part 64 is formed at one end part of the push button 60 so that the pressing part 64 fixes the dropper tube connector 90 while pressing one surface of the dropper tube connector 90. In this case, the push button 60 is coupled to the vertically movable member 50, and simultaneously fixed while being fitted between the vertically movable member 50 and the guide member 80.

[0056] Meanwhile, the push button 60 and the dropper tube connector 90 are formed of an elastic material such that the shape thereof may be deformed while being easily compressed and restored, and may be formed of a thermosetting resin or a thermoplastic resin, in which the thermosetting resin may be formed of any one or more of an epoxy resin, an amino resin, a phenol resin, and a polyester resin, and the thermoplastic resin may be formed of any one or more of polyethylene, acrylic resin, polypropylene, polystyrene, polyvinyl chloride, Teflon, nylon, and polyacetal resin, and particularly, may be formed of an elastomer-based thermoplastic elastomer (TPE) material. Obviously, the push button 60 and the dropper tube connector 90 are not limited to the above-described materials, and may be formed of various materials within a range having constant elasticity.

[0057] The dropper tube 70 is coupled to one side of the dropper tube connector 90 to extend downward from the dropper part 20. The dropper tube 70 is a component that sucks or discharges the cosmetic contents through a change in the internal volume of the push button 60 by rotation or pressing of the outer cap 40, in which one open side thereof is connected to an internal space of the push button 60 and moves up and down together with the vertically movable member 50 when the outer cap 40 is rotated with respect to the inner cap 30.

[0058] A suction outlet 72 is formed at an end part of the dropper tube 70, and the cosmetic contents are sucked or discharged through the suction outlet 72. The dropper tube 70 may have a tube shape with both open sides and an empty inside and may be formed of a glass material such that an inside of the dropper tube 70 may be seen, but is not limited thereto, and may be variously formed in consideration of the type, usability, durability, and design factors of the cosmetic material sucked into the inside.

[0059] As illustrated in FIG. 3, at least a portion of the dropper tube 70 may pass through the inlet part 12 of the container body 10 and may be inserted into the container body 10, and one end part of the dropper tube 70, that is, an outer edge portion of the suction outlet 72 may make contact with the bottom surface of the container body 10. The end part of the dropper tube 70 is inserted into and seated on the dropper tube seating groove 16 of the container body 10, and such a state is maintained even when the vertically movable member 50 moves up and down by the attachment or detachment of the container body 10 and the dropper part 20 and the rotation of the outer cap 40. Therefore, the cosmetic contents accommodated in the container body 10 are used without any leftovers, and the dropper tube 70 is not inclined to any one side.

[0060] The guide member 80 is fixedly coupled to the vertically movable member 50 to fix the dropper tube connector 90 together with the push button 60. The guide member 80 moves up and down together with the vertically movable member 50 when the outer cap 40 is rotated with respect to the inner cap 30, and guides a linear movement of the dropper tube 70 due to elastic deformation or restoration of the dropper tube connector 90 while surrounding an outer side of the dropper tube 70 by at least a portion of the guide member 80.

[0061] An insertion groove 82 may be formed between an upper inner wall and an outer wall of the guide member 80 so that the dropper tube connector 90 may be inserted thereinto, a through-hole 84 may be formed at the center of the guide member 80 so that the dropper tube 70 may extend by passing therethrough, and at least a portion of the guide member 80 may be inserted into the wiper 14 of the container body 10 when the container body 10 is fastened to the dropper part 20.

[0062] The dropper tube connector 90 is formed in the internal space of the push button 60 to elastically support the dropper tube 70, and is elastically deformed or restored by the dropper tube 70 to change the internal volume of the push button 60.

[0063] As illustrated in FIG. 4, the dropper tube connector 90 may include a first coupling part 92 fixedly coupled while being fitted between the push button 60 and the guide member 80, a second coupling part 94 fixedly coupled to the dropper tube 70, and an elastic deformation part 96 connecting the first coupling part 92 and the second coupling part 94 to each other and elastically deformed or restored when the container body 10 is attached or detached from the dropper part 20.

[0064] The first coupling part 92 is a portion extending at a predetermined height along an outer edge of the dropper tube connector 90, in which one side thereof is inserted into the insertion groove 82 of the guide member 80 and the other side thereof makes close contact with the push button 60 and is fixed while being pressed by the pressing part 64 of the push button 60. In addition, the second coupling part 94 is a portion that is relatively widely formed at the center of the dropper tube connector 90, is coupled while surrounding one end part of the dropper tube 70, and has a connection hole 94a formed at the center thereof to connect the internal space of the push button 60 and one open side of the dropper tube 70.

[0065] The elastic deformation part 96 may include a first connection section 96a extending from the first coupling part 92 toward the second coupling part 94, a second connection section 96b extending from the second coupling part 94 toward the first coupling part 92, and a third connection section 96c connecting the first connection section 96a and the second connection section 96b to each other, in which both side surfaces of the third connection section 96c face each other while being spaced apart from the first coupling part 92 and the second coupling part 94 by a predetermined distance. That is, the elastic deformation part 96 connecting the first coupling part 92 and the second coupling part 94 has a bent structure in at least two portions, so that when the dropper part 20 is separated from the container body 10 and the cosmetic contents are applied to the skin, the dropper part 20 may be conveniently used while minimizing shaking of the dropper tube 70 with respect to the push button 60 and the guide member 80, and when the dropper tube connector 90 is elastically deformed by the dropper tube 70, the bent portion of the elastic deformation part 96 may be unfolded to expand the deformation range, thereby maximizing utilization of the internal space of the dropper part 20. In this case, it is preferable that the first connection section 96a and the second connection section 96b of the elastic deformation part 96 have mutually different heights and are connected to each other by the third connection section 96c, and the elastic deformation part 96 is symmetrical with respect to the center of the third connection section 96c.

[0066] As described above, the elastic deformation part 96 of the dropper tube connector 90 connects the first coupling portion 92 and the second coupling portion 94 to each other in a state where at least some sections of the elastic deformation part 96 are bent, and when the container body 10 is coupled to the dropper part 20 and the dropper part 20 moves up and down, the at least some sections of the elastic deformation part 96 are unfolded while being pushed up into the internal space of the push button 60 by the dropper tube 70, so that the first coupling portion 92 and the second coupling portion 94 are linearly connected to each other, and accordingly, as the internal volume of the push button 60 is changed, the cosmetic contents accommodated in the container body 10 may be sucked into the dropper tube 70 or air in the dropper tube 70 may be discharged to the outside.

[0067] Meanwhile, when the outer cap 40 is rotated with respect to the inner cap 30 in a state where the end part of the dropper tube 70 makes close contact with an inner bottom surface of the container body 10 by the dropper tube connector 90, the vertically movable member 50, the push button 60, and the dropper tube 70 may move up and down together by a predetermined section. That is, when the container body 10 is fastened to the dropper part 20, the dropper tube 70 is seated on the dropper tube seating groove 16 of the container body 10, and the vertically movable member 50, the push button 60, the guide member 80, and the dropper tube connector 90 are vertically reciprocated without rotation around the dropper tube 70 by the operation of the dropper part 20 while maintaining such a state, so that the dropper tube 70 may be stably stored in the container body 10 without being inclined to any one side.

[0068] FIGS. 5 and 8 are views illustrating an operation of the remainder-preventing dropper container according to the embodiment of the present disclosure, which describes a process of operating the remainder-preventing dropper container according to the embodiment of the present disclosure with respect to FIGS. 5 and 8.

[0069] FIG. 5 is a sectional view illustrating a state where a push button is lifted up by rotation of an outer cap according to the embodiment of the present disclosure, FIG. 6 is a sectional view illustrating a state where a container body is separated from a dropper part according to the embodiment of the present disclosure, FIG. 7 is a sectional view illustrating a state where the container body is coupled to a dropper according to the embodiment of the present disclosure, and FIG. 8 is a sectional view illustrating a state where the push button is lifted down by rotation of the outer cap according to the embodiment of the present disclosure.

[0070] In order to use the remainder-preventing dropper container according to the embodiment of the present disclosure, the outer cap 40 of the dropper part 20 is rotated so that the push button 60 protrudes from the upper part of the outer cap 40, and the fastening between the container body 10 and the dropper part 20 is continuously released so that the dropper part 20 is separated from the container body 10.

[0071] As illustrated in FIG. 5, when the outer cap 40 is rotated in any one direction from the inner cap 30 screw-coupled to the container body 10, the lifting protrusion 42 formed on the outer cap 40 is moved within the lifting spiral groove 52 of the vertically movable member 50. In this case, since the linear guide protrusion 32 of the inner cap 30 is fitted into the linear guide groove 54 of the vertically movable member 50, the vertically movable member 50 is not rotated, and the lifting protrusion 42 of the outer cap 40 is horizontally rotated to push the vertically movable member 50 upward and move the vertically movable member 50 linearly upward.

[0072] Simultaneously, as the push button 60, the dropper tube 70, the guide member 80, and the dropper tube connector 90, which are coupled to an inner side of the vertically movable member 50, are linearly moved upward together, the push button 60 protrudes upward from the outer cap 40, and as the dropper tube connector 90 that is elastically deformed by the dropper tube 70 is elastically restored and the internal volume of the push button 60 is increased, the cosmetic contents inside the container body 10 are introduced through the suction outlet 72 of the dropper tube 70. Simultaneously, the dropper tube connector 60 pushes the dropper tube 70 toward a bottom of the container body 10 by an elastic restoring force thereof, so that the end part of the dropper tube 70 is maintained in a state of making close contact with the inner bottom surface of the container body 10.

[0073] As illustrated in FIG. 6, when the outer cap 40 is continuously rotated, the lifting protrusion 42 of the outer cap 40 is caught on an end part of the lifting spiral groove 52 of the vertically movable member 50, and thus the vertically movable member 50 and the inner cap 30 are rotated together, thereby releasing the screw-coupling between the container body 10 and the inner cap 30.

[0074] Thereafter, the dropper part 20 is separated from the container body 10, the end part 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 and use the cosmetic contents.

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

[0076] As illustrated in FIG. 7, when the outer cap 40 is rotated in the opposite direction, the vertically movable member 50 and the inner cap 30 are rotated together with the outer cap 40, so that the container body 10 and the inner cap 30 are screw-coupled to each other. In this case, the end part of the dropper tube 70 is inserted into and seated on the dropper tube seating groove 16 formed at the center of the bottom surface of the container body 10.

[0077] As illustrated in FIG. 8, when the outer cap 40 is continuously rotated from the inner cap 30 screw-coupled to the container body 10, the lifting protrusion 42 formed on the outer cap 40 is moved within the lifting spiral groove 52 of the vertically movable member 50. In this case, since the linear guide protrusion 32 of the inner cap 30 is fitted into the linear guide groove 54 of the vertically movable member 50, the vertically movable member 50 is not rotated, and the lifting protrusion 42 of the outer cap 40 is horizontally rotated to push the vertically movable member 50 downward and move the vertically movable member 50 linearly downward.

[0078] Simultaneously, as the push button 60, the dropper tube 70, the guide member 80, and the dropper tube connector 90, which are coupled to the inner side of the vertically movable member 50, are linearly moved downward together, the push button 60 is inserted into the outer cap 40, and the elastic deformation part 96 of the dropper tube connector 90 is bent and elastically deformed while being unfolded by the dropper tube 70, so that as the internal volume of the push button 60 is reduced, the air inside the dropper tube 70 is discharged to the outside through the suction outlet 72. In this case, the dropper tube connector 60 pushes the dropper tube 70 toward the bottom of the container body 10 by an elastic force thereof, so that the end part of the dropper tube 70 is maintained in a state of being seated on the dropper tube seating groove 16 of the container body 10.
