Description

Rotary discharge container

[0001] The present invention relates to a discharge container, and more particularly, to a rotary discharge container capable of minimizing the size relative to the storage capacity of contents while maximizing the use of internal space through a dual rotational operation structure.

[0002] In today's modern society, people of all ages and genders are using cosmetics according to their needs in accordance with the rapidly diversifying trend of the times. In particular, women are using various types of cosmetics and cosmetics and tools with various colors, and through research and development by cosmetics companies, a variety of high-quality cosmetics and tools are being released to the market every day.

[0003] If we classify the above cosmetics by their purpose of use, they are classified into facial cleansing cosmetics used to remove sebum, waste products, and pollutants from the skin surface, basic cosmetics used to provide the skin with an appropriate amount of moisture and oil, color cosmetics used to express beautiful colors, hair cosmetics used to remove foreign substances from the hair or scalp while protecting and nourishing the hair, and perfumes used to dissolve fragrances in alcohol and other substances to give off a scent to others.

[0004] As cosmetics like these were developed, the development of various cosmetic containers to hold the cosmetics also became necessary.

[0005] In general, among cosmetics, cosmetics in liquid or gel form, such as lotions, creams, gels, shampoos, and rinses, were stored and used in the past by simply using a container with an opening and closing function, and then taking the cosmetics out of the container with a makeup tool such as a puff or with fingers and applying them to the skin.

[0006] However, since the conventional cosmetic container must be used with the lid open, the cosmetic is completely exposed to the air and oxidized, and since the puff that has touched the skin during use is repeatedly brought into contact with the cosmetic, the cosmetic is contaminated by bacteria, viruses, mold, etc., which causes skin trouble or shortens the use period.

[0007] In addition, since these conventional cosmetic containers require the cosmetics to be taken out with a cosmetic tool such as a puff or with the fingers, there was a problem in that the amount of cosmetics used could not always be controlled consistently, resulting in waste of cosmetics and inconvenience in use.

[0008] Accordingly, a rotary dispensing cosmetic container was developed that minimizes deterioration and contamination during the use of cosmetics, is convenient to use, and allows for consistent control of the amount of cosmetics used.

[0009] As a prior art having such a structure, a piston-type cosmetic container having a puff is disclosed in Korean Patent No. 10-1868276 (hereinafter referred to as “prior art 1”), wherein prior art 1 includes: an outer container; an inner container having a first male screw portion formed therein; a piston fitted to a lower end of the inner container to block liquid cosmetics from being contained within the inner container; a screw member coupled to the piston and having a first female screw portion formed on an inner circumference thereof so as to be screw-connected to the first male screw portion while positioned outside the inner container; a nozzle portion coupled to an upper end of the inner container and having a nozzle hole formed therein so that cosmetics contained within the inner container are withdrawn by the rise of the piston; a puff coupled to the nozzle portion and applying the cosmetics to the user’s skin when in contact with the skin; and a cap detachably coupled to the nozzle portion or the inner container so as to isolate the puff from the outside.

[0010] In addition, a rotary cosmetic container is disclosed in Korean Patent Registration No. 10-2117100 (hereinafter referred to as “prior art 2”), which includes: a rotating part to which a rotational force is applied by a user; a container part that contains cosmetics and is raised and lowered by the rotation of the rotating part; an elevation guide part to which the rotating part is coupled to be relatively rotatable downward and to which at least a portion of the container part is inserted inside to guide the raising and lowering of the container part when the rotating part is relatively rotated; a piston part supported by the rotating part and formed to extend inwardly of the container part to pressurize the cosmetic in the container part as the container part is lowered; and a discharge part provided on an upper side of the container part and to discharge the cosmetic pressurized by the piston part.

[0011] The above-mentioned prior art 1 and 2 have an operating structure in which, when the outer container (rotating part) is rotated, the inner container (container part) coupled with the outer container (rotating part) and the screw are lowered, and the contents contained inside the inner container (container part) are compressed by a piston (piston part) and discharged to the outside.

[0012] However, in the above-mentioned prior arts 1 and 2, the piston (piston part) must reach the top of the inner container (container part) in order to use all the stored contents, and a screw fastening section is required between the outer container (rotating part) and the inner container (container part) by the distance that the piston (piston part) moves, and as a result, the overall length of the container inevitably becomes longer, which has the problem of reduced usability and portability.

[0013] Therefore, it became necessary to develop a rotary dispensing container that is more convenient to use and portable by reducing the overall length while accommodating a certain amount of contents inside.

[0018]

[0019] In order to solve the above problems, the present invention aims to provide a rotary dispensing container that is convenient to use and easy to carry by minimizing the size compared to the storage capacity of the contents while maximizing the use of the internal space through a dual rotation operation structure in which the contents and the lifting member are continuously operated by rotation operation so that the contents are discharged at a constant rate.

[0020] In order to achieve the above object, the present invention provides a rotary discharge container including an outer container having a first rotation restriction portion formed therein; an elevation member coupled to the outer container and moving linearly from the outer container; an operating member screw-connected to the elevation member and having a second rotation restriction portion formed therein; an inner container screw-connected to the operating member and having a storage space for accommodating contents; a rotary cap coupled to the inner container and having a discharge port formed therein; and a piston coupled to the elevation member and inserted into an inner space of the inner container.

[0021] Additionally, it may include an overcap that opens and closes the rotating cap while being detachably connected to the outer container.

[0022] In addition, an elevator guide wheel is formed extending upward on the inside of the outer container, and an elevator member is fitted to the outside of the elevator guide wheel, and a piston can be installed on the top.

[0023] In addition, a first lifting guide part is formed on the outer container, and a second lifting guide part is formed on the lifting member, and when fitted together, the lifting member can guide linear movement with respect to the outer container.

[0024] In addition, the first rotation limiting portion can be formed to be elastically deformable in the operating direction of the inner container while being spaced apart from the bottom of the outer container by a certain distance.

[0025] In addition, the first rotation limiting portion may include an elastic rib extending at a certain angle from the bottom surface of the outer container, and a hooking projection formed protruding on one surface of the elastic rib and hooked to the second rotation limiting portion.

[0026] In addition, a first screw portion is formed on the elevating member, and a first rotating screw portion is formed on the operating member, and they are screw-connected to each other, and the elevating member can be elevated by rotation of the operating member.

[0027] In addition, a second screw portion is formed on the operating member, and a second rotating screw portion is formed on the contents member, and they are screw-connected to each other, and the contents member can be raised and lowered along the operating member as it rotates.

[0028] In addition, the second rotation limiting portion may include a protruding rib extending along the outer circumference of the operating member, and a catch groove formed on one side of the protruding rib and catchably connected to the first rotation limiting portion.

[0029] In addition, a fitting groove is formed in the inner space of the above-mentioned content device so that at least a portion of the piston can be fitted into it.

[0030] In addition, during the descending operation of the above-mentioned content device, the content device may press the first rotation limiter, thereby releasing the first rotation limiter and the second rotation limiter from each other, thereby enabling the operating member to rotate together with the content device.

[0031] Additionally, a discharge valve that selectively opens and closes the discharge port may be formed in the discharge port.

[0032] According to an embodiment of the present invention, since the contents are discharged at a constant rate while the contents and the lifting member are operated continuously by rotation operation, there is an effect of making it convenient to use the contents for discharge.

[0033] According to an embodiment of the present invention, the double rotation operation structure maximizes the use of internal space while minimizing the size compared to the storage capacity of contents, thereby providing the effect of easy portability.

[0034] According to an embodiment of the present invention, since the contents and the lifting member are sequentially screw-fastened in opposite directions by a rotation operation, the overall length of the container is reduced, making it compact and improving its aesthetic appeal.

[0035] According to an embodiment of the present invention, since each component for the dual rotation operation structure is organically combined and operates with each other, the discharge operation of the contents can be performed stably and smoothly.

[0052] As illustrated, a rotary discharge container according to one embodiment of the present invention may be configured to include an outer container (10), an elevating member (20), an operating member (30), an inner container (40), a rotary cap (50), and a piston (60).

[0053]

[0054] The button rotation discharge container according to one embodiment of the present invention is described by dividing it into each component as follows.

[0055]

[0056] The above outer container (10) has a container (40) attached to one side, and together with the container (40), forms the exterior of a rotary discharge container. An elevating member (20) and an operating member (30) are installed in the inner space of the outer container (10), and at least a portion of the container (40) and the rotary cap (50) can be inserted.

[0057] As shown in FIGS. 2 and 3, an elevation guide protrusion (12) may be formed on the outer container (10). The elevation guide protrusion (12) is formed to extend upward from the inner center of the outer container (10), an elevation member (20) is fitted to the outside thereof, and a piston (60) is seated on the upper end. A first elevation guide part (12a) is formed on the outside of the elevation guide protrusion (12). The first elevation guide part (12a) guides the linear movement of the elevation member (20) while being fitted into the elevation member (20). The first elevation guide part (12a) is formed to extend in a long direction in the operating direction of the elevation member (20), that is, in the longitudinal direction of the elevation guide protrusion (12), and may be arranged to be spaced apart from each other by a certain interval along the outer periphery of the elevation guide protrusion (12). It is preferable that the end of the first lifting guide part (12a) protrudes further than the upper end of the lifting guide wheel (12), and wraps around the outer side of the piston (60) mounted on the lifting guide wheel (12).

[0058] As shown in Fig. 5, a first rotation limiting portion (14) may be formed at a predetermined distance outside the elevating guide wheel (12). The first rotation limiting portion (14) is a portion that is engaged with at least a portion of the operating member (30) to limit the rotation of the operating member (30), and is formed to partially extend in a circle along the outer circumference of the elevating guide wheel (12) and may be elastically deformed in the operating direction of the inner container (40) while being spaced at a predetermined distance from the bottom of the outer container (10). The first rotation limiting portions (14) are preferably formed in at least one pair to stably limit the rotation of the operating member (30), and are arranged symmetrically with respect to the elevating guide wheel (12).

[0059] The first rotation limiting member (14) may include an elastic rib (14a) extending upwardly and inclinedly from the bottom surface of the outer container (10), and a catch (14b) protrudingly formed on one surface of the elastic rib (14a) and engaging with the second rotation limiting member (34). The elastic rib (14a) is formed to be inclined at a certain angle toward the inner container (40) to elastically support the catch (14b), and the catch (14b) is released from engaging with the second rotation limiting member (34) when pressed by the descending inner container (40). That is, when the first rotation limiting part (14) and the second rotation limiting part (34) are engaged and connected, the rotation of the operating member (30) from the outer container (10) is restricted, and when the engaging connection of the first rotation limiting part (14) and the second rotation limiting part (34) is released, the rotation of the operating member (30) from the outer container (10) becomes possible. At this time, an insertion hole (14c) is formed on the lower side of the first rotation limiting part (14) so ​​that the elastically deformed first rotation limiting part (14) can be inserted.

[0060] And, a catch (16) can be formed at a certain distance from the outside of the above-mentioned lifting guide wheel (12). The catch (16) is arranged between the first rotation limiting parts (14) adjacent to each other, and a catch projection (16a) is formed at the end thereof to protrude toward the center, and an operating member (30) is rotatably caught and connected to the catch projection (16a).

[0061] Meanwhile, an overcap (70) is coupled to one side of the outer container (10) to open or close the rotary cap (50). As shown in FIG. 4, the overcap (70) is detachably coupled to the outer container (10) while covering the rotary cap (50), and when in use, it is separated from the outer container (10) to expose the rotary cap (50) to the outside, and when stored or carried, it is coupled to the outer container (10) to protect the rotary cap (50). In the rotary discharge container according to the embodiment of the present invention, a projection and a groove are formed on the outer container (10) and the overcap (70) to be coupled to each other as an example, but the present invention is not limited thereto, and the overcap (70) may have various types of coupling structures within a range in which it can be easily coupled to and detached from the outer container (10), such as an undercut coupling, a screw coupling, a forced-fit coupling, or a magnetic coupling.

[0062] A sealing protrusion (72) may be formed on the above overcap (70). The sealing protrusion (72) is formed to protrude from the inner upper surface of the overcap (70) to the surface of the rotary cap (50), and when the outer container (10) and the overcap (70) are combined, it is inserted into the discharge port (54) of the rotary cap (50) to seal the discharge port (54), or to restrict the operation of the discharge valve (not shown) installed in the discharge port (54) by pressing at least a portion of the discharge valve.

[0063]

[0064] The above-mentioned lifting member (20) is connected to the outer container (10) so as to be linearly movable, is screw-connected to the operating member (30), and is linearly moved from the outer container (10) by the rotational operation of the operating member (30).

[0065] The above-mentioned lifting member (20) is formed as a cylinder with both sides open and is installed inside the outer container (10). A piston (60) is fixedly connected to one side, and at least a portion of the outer container (10) and the piston (60) can be inserted into the center inside. The above-mentioned lifting member (20) is installed between the lifting guide wheel (12) of the outer container (10) and the operating member (30), and while converting the rotational operation of the above-mentioned operating member (30) into an elevating operation, the piston (60) coupled to the end thereof is moved linearly within the inner container (40).

[0066] As shown in FIGS. 2 and 3, a first screw portion (22) may be formed on the elevating member (20). The first screw portion (22) is formed to protrude from the outer periphery of the elevating member (20) and is screw-connected to an operating member (30) coupled to the outer side of the elevating member (20). When the operating member (30) and the elevating member (20) are screw-connected to each other, the elevating member (20) can move up and down. At this time, it is preferable that the first screw portion (22) be formed to be inclined at an appropriate angle along the outer periphery of the elevating member (20) in consideration of smooth operation and movement distance of the elevating member (20).

[0067] Meanwhile, a second lifting guide part (24) may be formed on the lifting member (20). The second lifting guide part (24) is formed by being recessed into the inner periphery of the lifting member (20), and the first lifting guide part (12a) of the outer container (10) is fitted into the second lifting guide part (24) to guide the linear movement of the lifting member (20) with respect to the outer container (10). The second lifting guide part (24) may be formed to extend in a long direction in the operating direction of the lifting member (20), that is, in the longitudinal direction of the lifting guide protrusion (12), and may be arranged at a constant interval along the inner periphery of the lifting member (20).

[0068]

[0069] The above operating member (30) is installed on the inside of the outer container (10) and is coupled between the lifting member (20) and the inner container (40) to guide or operate the inner container (40) and the lifting member (20) in opposite directions.

[0070] As shown in Fig. 6, the operating member (30) has a hollow cylindrical shape, and can be screw-coupled while wrapping around the outside of the elevating member (20), and the inner member (40) can be screw-coupled while wrapping around the outside of the operating member (30). That is, the elevating member (20) and the inner member (40) are screw-coupled to the inside and outside of the operating member (30), respectively, and the inner member (40) and the elevating member (20) are sequentially screw-coupled in opposite directions by rotation operation, thereby forming a dual rotational operation structure.

[0071] The operating member (30) may be formed with a first rotating screw portion (32). The first rotating screw portion (32) is formed to partially protrude from the inner circumference of the operating member (30) and is screw-connected with the first screw portion (22) of the elevating member (20). The first rotating screw portion (32) is fixed during the elevating operation of the contents (40), and after the elevating operation of the contents (40) stops, it rotates together with the contents (40) and is screw-connected with the first screw portion (22) of the elevating member (20) to move the elevating member (20) in a straight line.

[0072] The above-described operating member (30) may include a second rotation limiting portion (34). The second rotation limiting portion (34) is formed to protrude with a certain length on the outer periphery of the operating member (30) and limits the rotation of the operating member (30) together with the first rotation limiting portion (14). The operating member (30) is maintained in a fixed state to the outer container (10) during the operation of the rotary discharge container, and when the engaging connection between the first rotation limiting portion (14) of the outer container (10) and the second rotation limiting portion (34) of the operating member (30) is released, the operating member (30) can rotate together with the inner container (40).

[0073] The second rotation limiting portion (34) may include a protruding rib (34a) extending along the outer circumference of the operating member (30), and a catching groove (34b) formed on one side of the protruding rib (34a) to engage with the first rotation limiting portion (14). At least a portion of the protruding rib (34a) engages with the catching portion (16) of the outer container (10) to prevent the operating member (30) from being separated from the outer container (10), and the catching groove (34b) is formed as a groove partially cut in the protruding rib (34a) so that the catching projection (14b) of the first rotation limiting portion (14) can be inserted into or removed from it. That is, the engaging projection (14b) of the first rotation limiting portion (14) is inserted into the engaging groove (34b) of the second rotation limiting portion (34) so ​​that the rotation of the operating member (30) with respect to the outer container (10) is restricted, and when the engaging projection (14b) of the first rotation limiting portion (14) is pressed and moved by the inner member (40), it comes out from the engaging groove (34b) of the second rotation limiting portion (34) so ​​that the rotation of the operating member (30) with respect to the outer container (10) is enabled. It is preferable that the engaging grooves (34b) of the second rotation limiting portion (34) are formed in at least one pair, like the first rotation limiting portion (14), and are arranged symmetrically to each other.

[0074] Meanwhile, a second screw portion (36) may be formed on the operating member (30). The second screw portion (36) is formed to protrude from the outer periphery of the operating member (30), is screw-connected with the inner member (40), and can be raised and lowered along the operating member (30) as the inner member (40) rotates. At this time, it is preferable that the second screw portion (36) be formed to be inclined at an appropriate angle along the outer periphery of the operating member (30) in consideration of the smooth operation and movement distance of the inner member (40).

[0075]

[0076] The above content (40) is screw-coupled to the operating member (30) and rotates together with the rotary cap (50) to move up and down along the operating member (30).

[0077] As shown in FIGS. 2 and 3, the contents container (40) is a rigid cylindrical shape with a space of a certain size inside, and a storage space (S) is formed inside the contents container to accommodate liquid or gel-like cosmetic contents. Of course, the contents container (40) is not limited to a rigid cylindrical shape, and may be formed in various shapes or materials in consideration of the type of cosmetic contents stored inside, usability, design elements, etc.

[0078] An opening (42) into which a piston (60) is inserted may be formed on one side of the above-mentioned content member (40), and a through hole (44) through which a lifting member (20) and an operating member (30) pass may be formed on the opposite side of the opening (42).

[0079] The above-mentioned content member (40) may be formed with a second rotating screw portion (46). The second rotating screw portion (46) is formed to protrude from the inner wall of the content member (40) and is screw-connected with the second screw portion (36) of the operating member (30). The second rotating screw portion (46) is rotated by the rotating cap (50) and is screw-connected with the second screw portion (36) of the operating member (30) to raise and lower the content member (40) along the operating member (30).

[0080] As shown in Fig. 4, a fitting groove (48) may be formed in the inner space of the contents container (40). The fitting groove (48) is a groove extending along the inner wall circumference of the contents container (40), into which at least a portion of the piston (60) is fitted, and the piston (60) can be maintained in a state of being fixed to the bottom of the contents container (40) until the piston (60) is pushed with a force of a certain amount or more. Through such a coupling structure, the piston (60) is fixed during the process of filling contents of the rotary discharge container, its position can be confirmed, and the piston (60) is operated by being detached from the fitting groove (48) during the first use.

[0081] Meanwhile, as seen in FIGS. 2 and 3, a first fitting portion (43) is formed on the inner container (40), and a second fitting portion (53) is formed on the rotary cap (50) so that they can be coupled to each other so as not to rotate without rotation. The first fitting portion (43) and the second fitting portion (53) are formed as protrusions or grooves on the portion where the inner container (40) and the rotary cap (50) come into contact, i.e., on the outer periphery of the inner container (40) and the inner periphery of the rotary cap (50), so that they can be coupled to each other by being fitted together. Of course, the first fitting portion (43) and the second fitting portion (53) may also be formed as protrusions on the outer periphery of the inner container (40) and the inner periphery of the rotary cap (50), so that they are interlocked with each other.

[0082]

[0083] The above rotary cap (50) covers the opening (42) of the contents container (40) and is fixedly connected to the outside of the contents container (40), and when rotated by the user, it rotates the contents container (40) connected to the inside thereof.

[0084] The rotary cap (50) may be formed with a discharge port (52) for discharging cosmetic contents to the outside. The discharge port (52) is formed on one side of the container (40), particularly on the side facing the direction of movement of the piston (60), and a discharge surface (54) that directly comes into contact with a cosmetic tool or a user's finger may be formed on the outside of the discharge port (52). The discharge surface (54) is formed as a soft curved surface, but for the sake of convenience of use, it is preferable that it be formed to become more convex from the edge of the rotary cap (50) toward the center. In the rotary discharge container according to the embodiment of the present invention, the discharge port (52) is illustrated as being located at the center of the discharge surface (54), but is not limited thereto, and the shape, number, or location of the discharge port (52) may be variously changed within a range in which the cosmetic contents can be easily discharged to the outside.

[0085] Meanwhile, a discharge valve (not shown) for opening and closing the discharge port (52) of the rotary cap (50) may be further formed. For example, the discharge valve may be formed of a soft material and may be formed as a check valve that selectively opens or closes the discharge port (52) by being operated by the discharge pressure of the cosmetic contents. The above discharge valve (not shown) is formed of an elastic material for internal sealing of the contents (40) and smooth opening and closing of the discharge port (52), and is preferably formed of one or more materials of urethane rubber, natural rubber, elastomer, NBR (nitrile-butadiene rubber), silicone, or polypropylene, polyethylene, ABS (Acrylonitrile Butadiene Styrene) having elasticity, and in particular, it is most preferably formed of TPE (Thermo Plastic Elastomer), which is a material between rubber and plastic that is soft and durable.

[0086]

[0087] The above piston (60) is fixedly connected to one side of the lifting member (20) and inserted into the inner space of the contents (40).

[0088] As shown in Fig. 4, the piston (60) can be an outer wall of any one of the storage spaces (S) of the cosmetic contents while blocking the through hole (44) of the container (40). As the container (40) moves downward toward the inside of the outer container (10) or the lifting member (20) moves upward toward the inside of the container (40), the piston (60) moves upward of the container (40) and pushes the cosmetic contents contained in the container (40) and discharges them through the discharge port (52).

[0089] A sealing ring (62) may be formed on the outside of the piston (60). The sealing ring (62) is formed to extend along the outer circumference of the piston (60) and is in close contact with the inner wall of the inner container (40), and in this state moves linearly within the inner container (40). The outer surface of the sealing ring (62) may be formed to be curved so that it can be in close contact with the inner circumference of the inner container (40) at at least two points.

[0090] Meanwhile, a protrusion (64) may be formed on one surface of the piston (60). The protrusion (64) is formed to protrude in the center of the upper surface of the piston (60), and is inserted into the discharge port (52) of the rotary cap (50) when the piston (60) is moved to the upper portion of the container (40). Accordingly, when the piston (60) is completely moved to the inner upper surface of the rotary cap (50), all of the cosmetic contents contained in the container (40) can be discharged to the outside without being left behind.

[0091]

[0092] FIGS. 7 to 10 are drawings illustrating the operation process of a rotary discharge container according to an embodiment of the present invention, and with reference to these drawings, the use process of a rotary discharge container according to an embodiment of the present invention will be described.

[0093] FIG. 7 is a cross-sectional view illustrating an appearance of an overcap separated from an outer container according to an embodiment of the present invention, FIG. 8 is a cross-sectional view illustrating an appearance of an inner container being lowered by rotating a rotary cap according to an embodiment of the present invention, FIG. 9 is a cross-sectional view illustrating an appearance of an inner container being completely lowered by continuously rotating a rotary cap according to an embodiment of the present invention, and FIG. 10 is a cross-sectional view illustrating an appearance of an elevating member being raised by further rotating a rotary cap according to an embodiment of the present invention.

[0094] In order to use the rotary discharge container according to the embodiment of the present invention, as shown in FIG. 7, the overcap (70) is separated from the outer container (10) and the rotary cap (50) is exposed to the outside.

[0095] Thereafter, as shown in Fig. 8, when the rotary cap (50) of the outer container (10) is rotated in one direction, the inner container (40) coupled to the inner side of the rotary cap (50) rotates together. At this time, the first rotation restriction part (14) of the outer container (10) and the second rotation restriction part (34) of the operating member (30) are engaged with each other, and the rotation of the operating member (30) coupled with the inner container (40) by screw is restricted.

[0096] At the same time, as the second rotating screw part (46) of the contents container (40) moves along the second screw part (36) of the operating member (30), the contents container (40) moves toward the inside of the outer container (10), and as the piston (60) mounted on the lifting guide wheel (12) of the outer container (10) changes its position to the upper part of the contents container (40), the cosmetic contents contained in the storage space (S) of the contents container (40) are pushed by the piston (60) and discharged through the discharge port (52).

[0097] Thereafter, as shown in FIG. 9, when the rotary cap (50) is continuously rotated in one direction to completely lower the contents (40) into the inside of the outer container (10), the contents (40) presses the first rotation limiting part (14), and the engagement between the first rotation limiting part (14) and the second rotation limiting part (34) is released, and the operating member (30) is freed from the outer container (10). That is, the engaging projection (14b) of the first rotation limiting portion (14) is inserted into the engaging groove (34b) of the second rotation limiting portion (34) so ​​that the rotation of the operating member (30) with respect to the outer container (10) is maintained in a restricted state, and then, as the engaging projection (14b) of the first rotation limiting portion (14) is pressed and moved by the inner member (40), it comes out from the engaging groove (34b) of the second rotation limiting portion (34), so that the rotation of the operating member (30) with respect to the outer container (10) becomes possible.

[0098] Thereafter, as shown in Fig. 10, when the rotary cap (50) is further rotated in one direction, the rotary cap (50), the contents (40), and the operating member (30) rotate together. At this time, the first lifting guide part (12a) of the outer container (10) is fitted into the second lifting guide part (24) of the lifting member (20), and the lifting member (20) screw-connected to the operating member (30) is restricted from rotating.

[0099] At the same time, as the first rotary screw portion (32) of the operating member (30) and the first screw portion (22) of the lifting member (20) are released from the screw connection, the lifting member (20) and the piston (60) coupled with the lifting member (20) are moved in a straight line in the upper direction of the contents container (40), and the cosmetic contents contained in the storage space (S) of the contents container (40) are pushed by the piston (60) and discharged through the discharge port (52) of the rotating cap (50).

[0100] Afterwards, the cosmetic contents discharged through the discharge surface (54) of the above-mentioned rotary cap (50) are applied evenly to the skin using a cosmetic tool such as a puff to apply makeup. After the makeup is finished, the rotary cap (50) is wrapped with the above-mentioned overcap (70) and combined with the outer container (10) for storage or carrying.
