Description

TWO-IN-ONE COSMETIC CONTAINER FOR BRUSH-APPLIED COSMETICS

The present invention relates to a cosmetic container, and more particularly, to a two-in-one cosmetic container for cosmetics applied with a brush.

Various types of cosmetics, such as mascara, concealer, and lip color, are available in liquid form. Typically, users use cosmetics by detaching the brush inserted into the container containing the cosmetics and applying the cosmetics on the brush to the desired area.

In the case of some cosmetics, two different types of cosmetics can be used together as needed, such as lip color and lip gloss, concealer and blemish essence, etc. Cosmetics such as mascara have the characteristic of quickly evaporating and drying, so a solution to dilute them is also used together. When two different types of cosmetics are used together, the user takes each cosmetic out of a different container and applies it to the required area with a brush, which is quite inconvenient. However, if they are mixed and stored in one container, each cosmetic cannot be used individually.

Accordingly, the present invention has been developed to solve the above-described problems, and one aspect of the present invention is to provide a two-in-one cosmetic container that can increase user convenience by allowing different cosmetic liquids to be used together.

Other objects of the present invention will become more apparent through the embodiments described below.

The present invention can be modified in various ways and has various embodiments, and specific embodiments are illustrated in the drawings and described in detail in the detailed description. However, this is not intended to limit the present invention to specific embodiments, and it should be understood that it includes all modifications, equivalents, and substitutes included in the spirit and technical scope of the present invention. In describing the present invention, if it is determined that a specific description of a related known technology may obscure the gist of the present invention, the detailed description thereof will be omitted.

The terminology used in this application is only used to describe specific embodiments and is not intended to limit the present invention. The singular expression includes the plural expression unless the context clearly indicates otherwise. In this application, it should be understood that the terms "comprises" or "has" and the like are intended to specify the presence of a feature, number, step, operation, component, part or combination thereof described in the specification, but do not exclude in advance the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts or combinations thereof.

The terms first, second, etc. may be used to describe various components, but the components should not be limited by the terms. The terms are used only to distinguish one component from another.

For convenience of explanation, the expressions “inner,” “outer,” “upper,” and “lower” are used in this specification. In the following description, “inner” refers to the side closer to the inside of the cosmetic container, and “outer” refers to the side farther from the inside of the cosmetic container. Meanwhile, references to “upper” and “lower” are based on a state in which the first container (125) is placed facing upward, as in FIGS. 1, 6, and 13. Of course, when the cosmetic container (300, 500, 700) according to an embodiment of the present invention is actually used, the upper direction mentioned in the specification may not match the actual upper direction.

Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. When describing with reference to the attached drawings, identical or corresponding components are given the same reference numerals regardless of the drawing symbols, and redundant descriptions thereof will be omitted.

FIG. 1 is a perspective view illustrating a cosmetic container (300) according to a first embodiment of the present invention, and FIGS. 2 and 3 are a front view and a cross-sectional view, respectively, of the cosmetic container (300) illustrated in FIG. 1. FIGS. 4 and 5 are cross-sectional views illustrating a first container (125) and a pump module (140) of the cosmetic container (300) illustrated in FIG. 1, respectively.

Referring to FIGS. 1 to 5, the cosmetic container (300) according to the present embodiment is characterized in that when the first container (125) at the top is pressurized downward, the first content (not shown) injected into the inside of the first container (125) is discharged through the discharge hole (210) of the solder (200) by the pump module (140). In addition, the inside of the second container (220) is filled with the second content, and the second content can be used by being mixed and diluted with the injected first content.

If the cosmetic container (300) according to the present embodiment is a mascara container, the second content may be mascara liquid and the first content may be saline solution, etc. Therefore, the user can conveniently use the mascara liquid by diluting it with saline solution or by dissolving the hardened mascara liquid. Of course, the cosmetic container (300) according to the present invention is not limited to a mascara container, and there are no restrictions on the type, nature, and use of the first content and the second content.

Referring to FIGS. 1 to 5, a cosmetic container (300) according to the present embodiment may include an overcap (105), a first container (125), a container packing (130), a pump module (140), a sole (200), and a second container (220). Although there are slight differences between the first embodiment, the second embodiment, and the third embodiment of the present invention, if there are corresponding components, reference numerals used in connection with the second embodiment or the third embodiment may be used in the description of the first embodiment, and vice versa.

The overcap (105) may have a side wall (116) forming a hollow cylindrical shape to form an accommodation space (115; see FIG. 7) on the inside, and may accommodate a first container (125), a pump module (140), and a part of the sole (200) within the accommodation space (115). A support protrusion (194) for supporting a sole head (202; see FIG. 8) of the sole (200) may be formed inside the overcap (105), and a through hole (193; see FIG. 7) configured to allow a sole body (218; see FIG. 8) of the sole (200) to pass through may be formed on the inside of the support protrusion (194).

An open area (114) may be formed on the upper portion of the overcap (105), and the open area (114) may be formed across the upper surface and the circumferential surface of the overcap (105) as illustrated. More specifically, the open area (114) may be formed on the entire upper surface and a portion of the circumferential surface of the overcap (105), and a portion of the first container (125) may be exposed through the open area (114). The open area (114) exposes a portion of the circumferential surface and the upper surface of the first container (125) inserted into the inside of the overcap (105) to the outside, which allows the user to pressurize the first container (125) downward and also determine the amount of contents remaining in the first container (125). Since the upper portion of the overcap (105) has a height corresponding to the upper portion of the first container (125), the possibility of the first container (125) being unintentionally pressurized can be reduced compared to a case where the upper portion of the first container (125) protrudes beyond the upper portion of the overcap (105).

As in the illustrated embodiment, since the open area (114) is formed over the entire upper surface of the overcap (105), the stand (200), the pump module (140), and the first container (125) can be easily mounted in sequence within the receiving space (115). After the assembly of the first container (125), the pump module (140), and the stand (200) within the receiving space (115) is completed, they are firmly fixed to each other so as not to come off through the open area (114) on the upper portion of the overcap (105). For example, an inwardly protruding catch (192) may be provided on the inner circumference of the overcap (105). The catch (192) can be formed at a position corresponding to the upper portion of the solder head (202), and the solder head (202) can be fixed in place as the solder head (202) is inserted between the catch (192) and the support protrusion (194).

When assembling the cosmetic container (300) according to the present embodiment, the manufacturer may insert the stem (200) through the open area (114) of the overcap (105), and then press-fit the stem body (218) so that it passes through the through hole (193) first, and then the stem head (202) passes through the catch (192). When the stem head (202) passes through the catch (192), the stem head (202) can be fixed between the catch (192) and the support protrusion (194), and the manufacturer may then sequentially insert and assemble the connecting member (185), the elastic member (158), the housing cover (145), the piston (165), the guide (170), and the housing (155).

The overcap (105) can be detachably coupled to the second container (220), and for this purpose, a coupling means such as a female screw (196) can be formed on the inner surface of the lower portion. Since the solder body (218) of the solder (200) protrudes to the lower portion of the overcap (105) through the through hole (193), when the overcap (105) is coupled to the second container (220), the solder body (218) can be inserted into the interior of the second container (220).

As described above, the first container (125) can accommodate the first content therein, and when a user presses downward on the first container (125), the first content can be injected into the interior of the second container (220) through the discharge passage (208) of the sole (200) by the pump module (140). The first container (125) can be manufactured using a transparent material, which allows the user to easily determine the remaining amount of the first content injected into the interior of the first container (125) through the open area (114).

Referring to FIGS. 4 and 5, the first container (125) may include a receiving portion (120) in which first contents (not shown) are filled, and a neck portion (121) corresponding to an inlet portion. An opening (124) may be formed at a lower portion of the neck portion (121), and the interior of the receiving portion (120) may be opened to the outside through the opening (124). The neck portion (121) may have a smaller outer diameter than the receiving portion (120) so that it may be easily coupled with the pump module (140). Since the neck portion (121) has a reduced diameter, a portion of the first container (125) other than the neck portion (121) and the housing cover (145) may have similar outer diameters.

When the first container (125) is coupled to the pump module (140), the housing (155) of the pump module (140) can be inserted into the neck (121) of the first container (125) through the opening (124), and the neck (121) can be inserted between the housing cover (145) and the housing (155) of the pump module (140). In order for the first container (125) and the pump module (140) to be firmly coupled, an outwardly protruding catch (128) can be formed on the outer surface of the neck (121) of the first container (125). The catch (128) can be engaged with the catch (148) of the housing cover (145) to secure the first container (125) to the pump module (140).

Referring again to FIGS. 1 to 3, the container packing (130) can be coupled to the neck portion (222) of the second container (220) to provide a sealing function. The container packing (130) can have a packing body (134) that is open at both the top and bottom, and a flange (132) and a wiper (136) can be formed at the top and bottom of the packing body (134) (see FIG. 9). The outer surface of the packing body (134) can be coupled so as to be in close contact with the inner surface of the neck portion (222) of the second container (220). The container packing (130) can be made of a more flexible material (e.g., PE) than other parts of the cosmetic container (300), and can exhibit a slight elastic deformation when pressurized to provide a strong sealing function.

The flange (132) formed on the upper portion of the packing body (134) has an outwardly protruding structure and is formed along the entire circumference, so that it may have a ring shape. The flange (132) may be installed to be hung on the upper portion of the neck portion (222) of the second container (220). When the overcap (105) is coupled to the second container (220), the flange (132) is pressed between the support protrusion (194) of the overcap (105) and the neck portion (222) of the second container (220), so that the second container (220) can be strongly sealed.

A wiper (136) may be provided at the lower end of the container packing (130). The wiper (136) may be formed to be inclined inwardly, for example, and may be in close contact with the axial portion (216) of the solder body (218) as illustrated in FIG. 3. Accordingly, when the solder (200) is separated from the second container (220), the second contents remaining on the peripheral surface of the axial portion (216) may be wiped off by the wiper (136). A through hole (138; see FIG. 9) may be formed at the center of the wiper (136). The axial portion (216) of the solder body (218) may pass through the through hole (138).

The pump module (140) may be coupled to the neck (121) of the first container (125) and may serve to move the first contents contained in the first container (125) to the discharge passage (208) of the solder (200). The pump module (140) may include a housing cover (145), a housing (155), an elastic member (158), a piston (165), a guide (170), and a connecting member (185).

The housing cover (145) may serve to accommodate some components of the pump module (140) inside and at the same time assist in coupling the pump module (140) to the neck portion (121) of the first container (125). The housing cover (145) may have a structure in which both the upper and lower portions are open, and may be provided with a cover step (142) and an internal protrusion (141) inside.

The housing cover (145) can be divided into two parts with different diameters centered on the cover step (142). On the outside of the cover step (142), the outer circumferential surface (147) can have a larger diameter and a shape that extends upward. The outer circumferential surface (147) can be extended to a length corresponding to the length of the guide (170), and the catch (148) of the housing cover (145) can be formed on the inner surface at the upper end of the outer circumferential surface (147) extended in this manner. Here, the length corresponding to the length of the guide (170) can be the length of the entire guide (170), the length below the guide flange (172), or a length close thereto. This structure of the housing cover (145) can more firmly fix the first container (125) to a set position within the already required volume without increasing the volume more than necessary, thereby preventing the outer surface of the first container (125) from contacting the inner surface of the overcap (105), and thus preventing scratches from forming on the surface of the first container (125) made of a transparent material.

The lower part of the first container (125) can be supported by the cover step (142) while the catch (128) of the first container (125) is engaged with the catch (148) of the housing cover (145). As illustrated, the pressing projection (151) of the housing (155) can be positioned between the lower part of the first container (125) and the cover step (142), and a sealing member (149) can be further provided between the lower part of the first container (125) and the pressing projection (151).

The inner protrusion (141) is a hollow cylinder formed in the center of the lower portion of the housing cover (145) and has a structure in which both the upper and lower portions are open. The inner piston (162) of the piston (165) can be inserted into the upper portion of the inner protrusion (141), and a connecting member (185) can be inserted into the lower portion. More specifically, the inner protrusion (141) can extend upward again from a portion extending downward from the cover protrusion (142), so that a groove can be formed between the inner protrusion (141) and the cover protrusion (142), and the lower portion of the housing (155) can be inserted into the groove between the inner protrusion (141) and the cover protrusion (142). A catch protrusion (156) can also be formed at the lower portion of the housing (155).

The sealing member (149) may be formed of a flexible material such as silicone, and may be formed in an annular shape such as an O-ring. The sealing member (149) is positioned between the lower portion of the first container (125) and the cover step (142) of the housing cover (145), and provides a sealing function while allowing the catch (128) of the first container (125) to be in close contact with the catch (148) of the housing cover (145), thereby providing a more secure bond.

The housing (155) is a part inserted into the interior of the first container (125) and may have a structure in which both the top and bottom are open, and the lower part of the housing (155) may be inserted into the interior of the housing cover (145). An elastic member (158), a guide (170), and a piston (165) may be arranged inside the housing (155).

A housing inlet hole (152) is formed at the upper end of the housing (155). A disc valve (157) can be mounted in the housing inlet hole (152), and when the disc valve (157) is opened, the first content inside the first container (125) can flow into the inside of the housing (155) through the housing inlet hole (152).

The housing (155) can be fitted into the inner surface of the neck (121) of the first container (125) while its outer surface is extended long. The lower part of the housing (155) can have a shape that extends below the pressure projection (151), and this can be inserted and fixed between the cover step (142) of the housing cover (145) and the inner projection (141). The inner projection (141) of the housing cover (145) can be fitted into the inner surface of the housing (155) and extended upward, but can be extended to a position higher than the pressure projection (151). The upper part of the connecting member (185) can be inserted into the inner side of the inner projection (141), but even when the first container (125) is not pressed downward, the upper part of the connecting member (185) can be extended to a position higher than the inner projection (141) of the housing cover (145).

The outer surface of the housing (155) and the inner surface of the neck portion (121) are in close contact over a greater length, the outer surface of the inner protrusion (141) of the housing cover (145) and the inner surface of the housing (155) are also in close contact over a greater length, and a sealing member (149) is provided at the contact point between the first container (125), the housing cover (145), and the housing (155). It is also possible to strongly contact the outer surface of the neck portion (121) and the inner surface of the outer peripheral surface (147) of the housing cover (145). When the members in contact with each other are in close contact over a greater length, the watertightness is strengthened by a wider surface contact, and as a result, the first content can be prevented from leaking out of the first container (125) and the pump module (140). Even when the first container (125) is not pressurized downward, the connecting member (185) can support the entire inner protrusion (141) of the housing cover (145) from the inside, thereby further reducing the possibility of a gap occurring between the above members.

In addition, the catch (128) of the first container (125) is engaged with the catch (148) of the housing cover (145), and a sealing member (149) is placed under the lower part of the first container (125). Since the sealing member (149) is made of a material having some elasticity, the sealing member (149) allows the catches (128, 148) to adhere more strongly to each other, and conversely, the engagement of the catches (128, 148) allows the sealing member (149) to adhere more strongly to the surrounding area, thereby enhancing the sealing performance of the corresponding area.

A disc valve (157) may be provided in the housing inlet hole (152) at the upper end of the housing (155). The disc valve (157) may open or close the housing inlet hole (152) depending on the pressure inside the housing (155). For example, when the first container (125) is pressurized downward and the pressure inside the housing (155) increases, the disc valve (157) may rise to close the housing inlet hole (152), and when the external force applied to the first container (125) is removed and the pressure inside the housing (155) decreases, the disc valve (157) may descend to open the housing inlet hole (152) and the first content may flow into the inside of the housing (155) through the housing inlet hole (152).

The elastic member (158) can elastically support the first container (125) so that the first container (125) can move relatively to the guide (200). In the embodiments illustrated in FIGS. 1 to 5, the elastic member (158) is arranged between the lower portion of the housing cover (145) and the flange (188) of the connecting member (185). Since the guide head (202) of the guide (200) is fixed to the connecting member (185) and the first container (125) is fixed to the housing cover (145), the elastic member (158) allows the assembly of the first container (125), the housing cover (145) and the housing (155) to move relatively to the assembly of the guide (170), the connecting member (185) and the guide (200).

Referring to FIG. 5, a fixing projection (146) is formed in an annular shape on the lower surface of the housing cover (145), and a flange (188) is formed on the lower surface of the connecting member (185) at the lower surface of the connecting portion (186). An elastic member (158) may be mounted on the outer surface of the connecting member (185) and positioned between the lower surface of the housing cover (145) and the flange (188), and the upper surface of the elastic member (158) may be fixed to the inner surface of the fixing projection (146) and the lower surface may be supported on the flange (188). The elastic member (158) may correspond to a coil spring, but the present invention is not limited by the shape or material of the elastic member.

Since the elastic member (158) is provided at such a position, the elastic member (158) does not have to come into contact with the first contents. In the case where the elastic member (158) is formed of a material such as metal, as in the case of a coil spring, if the elastic member (158) comes into contact with the first contents, there is a concern that the contents may be contaminated or deteriorated by the elastic member (158), and the elastic member (158) may also be corroded by the liquid contents. However, by positioning the elastic member (158) on the outside of the pump module (140) as in the present embodiment, the life of the elastic member (158) can be increased while simultaneously preventing deterioration of the first contents and the second contents. In the present specification, the elastic member (158) used for the operation of the pump module (140) is also referred to as a first elastic member (158) in order to distinguish it from other elastic members (258; see FIGS. 10 to 12) to be described later.

The piston (165) may be positioned around the guide (170) and may serve to open or close the guide inlet hole (174) formed around the guide (170). The piston (165) may be arranged in a concentric shape and may have an inner piston (162) and an outer piston (164) with different diameters.

The inner piston (162) can be positioned inside the outer piston (164) and positioned so as to be in close contact with the outer surface of the guide (170). The inner piston (162) can rise or fall in conjunction with the elevation of the housing (155), thereby opening or closing the guide inlet hole (174).

The outer piston (164) can be positioned outside the inner piston (162) and can be positioned to be in close contact with the inner surface of the housing (155). When the housing (155) is lowered by the close contact of the outer piston (164), the piston (165) can also be lowered.

The guide (170) may have a passage (176) formed therein, thereby providing a passage through which the first content introduced into the interior of the housing (155) may move to the screw (200). The guide (170) is connected to the upper portion of the screw (200) by a connecting member (185), and an inner piston (162) of a piston (165) may be positioned around the guide. A guide flange (172) may be formed on the upper portion of the guide (170), and the guide flange (172) may limit the range in which the piston (165) may move upward.

The pump module (140) and the first container (125) coupled thereto are coupled to be relatively movable with respect to the guide (170) and the connecting member (185), but since the piston (165) is caught on the guide flange (172) and is restricted from upward movement beyond the designed range, not only the connecting member (185), but also the first container (125), the pump module (140), the guide (170), and the connecting member (185) are prevented from moving upward to a position beyond the designed range. As described above, this allows the overcap (105) not to support the first container (125) from above, and thus allows the open area (114) of the overcap (105) to be formed over the entire upper surface of the overcap (105).

A guide inlet hole (174) may be formed around the guide (170). The guide inlet hole (174) may be communicated with a moving passage (176) inside the guide (170). The moving passage (176) may be formed in the longitudinal direction of the guide (170), communicated with the guide inlet hole (174), and a lower portion may be communicated with a moving passage (184) of a connecting member (185). The first content introduced into the interior of the housing (155) through the guide inlet hole (174) may be moved to the discharge passage (208) of the solder (200) through the moving passage (176) of the guide (170) and the moving passage (184) of the connecting member (185). The guide inlet hole (174) may be opened or closed by the internal piston (162).

The connecting member (185) can serve to connect the pump module (140) and the screw (200), and a moving passage (184) can be formed inside. At the upper portion of the connecting member (185), a guide (170) can be inserted into the inside of the connecting member (185), and at the lower portion of the connecting member (185), the moving passage (184) of the connecting member (185) can be connected to a joining hole (206) of the screw head (202). The moving passage (184) can be formed along the entire length of the connecting member (185), and the first content introduced into the inside of the guide (170) can pass through the connecting member (185) and be introduced into the discharge passage (208) of the screw (200).

In the embodiments illustrated in FIGS. 1 to 5, a part of the solder head (202) is inserted into the moving passage (184) of the connecting member (185). More specifically, a boss (207) may be formed around a coupling hole (206) in the solder head (202). The boss (207) may extend upward from the solder head (202) and form a passage leading to the coupling hole (206) on the inside. Meanwhile, a connecting portion (186) having an expanded diameter in a shape corresponding to the boss (207) may be provided at the lower portion of the connecting member (185).

A male screw may be formed on the outer surface of the boss (207), and a corresponding female screw may be formed on the inner surface of the connecting portion (186), and the connecting member (185) may be connected to the solder head (202) by screw connection between the connecting portion (186) and the boss (207). When the connecting member (185) is connected to the solder head (202), the movement passage (184) of the connecting member (185) naturally communicates with the connecting hole (206) of the solder head (202). When the connecting member (185) is connected to the solder head (202) by screw connection in this way, even if a force is applied to pull the connecting member (185) upward, it will not easily come off.

As described above, a flange (188) may be provided at the lower portion of the connecting member (185). The flange (188) may serve to stably support the connecting member (185) on the flat portion (205) of the solder head (202) while fixing and supporting the lower portion of the elastic member (158).

The solder (200) may correspond to an applicator that has a brush (212) to enable use of the second content, and may provide a passage through which the first content moves into the interior of the second container (220). The solder (200) may largely include a solder head (202) and a solder body (218), and the solder body (218) may include an enlarged portion (214) configured not to pass through the through hole (138) of the container packing (130) and a reduced diameter portion (216) configured to pass through the through hole (138). A discharge passage (208) through which the first content can pass may be formed inside the solder (200), and the discharge passage (208) may be connected to the joining hole (206) at the upper portion of the solder (200) and to the discharge hole (210) at the lower portion.

The solder head (202) may be positioned on the upper portion of the support protrusion (194) inside the overcap (105). The solder head (202) may have a cylindrical shape with an open upper portion, including an outer circumferential surface (204) of a cylindrical shape and a flat portion (205) having a flat shape at the lower portion thereof. The solder head (202) may be configured so that a connecting member (185) is coupled to the center thereof. To this end, a boss (207) may be formed around a coupling hole (206) on the flat portion (205) of the solder head (202) as described above, and a male screw may be formed on the outer circumferential surface of the boss (207) corresponding to a female screw formed on the inner circumferential surface of the coupling portion (186) of the connecting member (185). The outer circumferential surface (204) of the solder head (202) is in contact with the inner circumferential surface of the overcap (105), which allows the solder (200) to be stably positioned without shaking within the receiving space (115) of the overcap (105).

The solder body (218) may be formed by protruding downward from the lower center of the solder head (202) and may correspond to a portion inserted into the interior of the second container (220). A discharge passage (208) through which the first content can move is formed inside the solder body (218), and the discharge passage (208) may be communicated with a discharge hole (210). The discharge hole (210) is located inside the second container (220) so that the first content can be sprayed into the interior of the second container (220).

The solder body (218) may include an expanding portion (214) and an axial portion (216). The axial portion (216) may have an outer diameter corresponding to the inner diameter of the through hole (138) of the container packing (130), and the expanding portion (214) may have an outer diameter larger than the axial portion (216). The expanding portion (214) may have an outer diameter smaller than the outer diameter of the solder head (202), and may have an outer diameter corresponding to the inner diameter of the through hole (193) of the overcap (105).

A joining groove (213) may be provided at the bottom of the axial portion (216) of the solder body (218), and the brush (212) may be joined to the axial portion (216) in such a way that a part of the brush (212) is inserted into the joining groove (213; see FIG. 8).

The discharge hole (210) may be located at the upper portion of the brush (212), so that the first content discharged through the discharge hole (210) may not be discharged directly to the brush (212), but may be discharged into the interior of the second container (220). Accordingly, the user can easily dilute and use the hardened second content using the sprayed first content.

The second container (220) is a container for accommodating second contents (not shown), and a neck portion (222) may be formed on the upper portion thereof. The second container (220) may have a hollow cylindrical shape with a closed lower portion and an open upper portion, and may be provided with a neck portion (222) whose diameter is reduced by a step (no drawing symbol). A male screw (224) may be formed on the outer circumference of the neck portion (222), and the male screw (224) may form a screw connection with a female screw (196) formed on the lower portion of the overcap (105).

If the user wants to use the second content injected into the second container (220) by hardening or diluting the second content, the user can press down on the first container (125). When the user presses down on a part of the first container (125) exposed through the open area (114) of the overcap (105), the elastic member (158) is deformed, and the housing cover (145) and the housing (155) can move downward together with the first container (125). The piston (165) can also move downward together with the housing (155), and the guide inlet hole (174) formed in the guide (170) can be opened. At this time, the pressure inside the housing (155) increases, so that the disc valve (157) can remain closed.

The first content filled inside the housing (155) can be introduced into the passage (176) of the guide (170) through the open guide inlet hole (174), and then discharged into the interior of the second container (220) through the passage (184) of the connecting member (185) and the discharge passage (208) of the solder body (218). Since the first content is discharged into the interior of the second container (220) rather than the brush (212) through the discharge hole (210) formed on the upper portion of the brush (212) in the solder body (218), the second content can be easily diluted.

When the external force applied to the first container (125) is removed, the first container (125), the housing cover (145), and the housing (155) can move upward again due to the restoring force of the elastic member (158). The piston (165) can also move upward together with the housing (155), and the guide inlet hole (174) formed in the guide (170) can be closed. At this time, since the first content inside the housing (155) is consumed and the volume inside the housing (155) increases as the housing (155) rises upward, the pressure inside the housing (155) is in a reduced state. As a result, the disk valve (157) can be opened, and the first content inside the first container (125) can flow into the housing (155) again.

When the user uses the second content, the user can hold and rotate the overcap (105) to separate the overcap (105) from the second container (220). When the overcap (105) is separated from the second container (220), the brush (200) is also separated from the second container (220), so that the user can use the second content (which may have been diluted by the first content) applied to the brush (212) of the brush (200).

According to the first embodiment of the present invention described above, the user can use the hardened or concentrated second content by diluting the second content with the first content by a simple pressurizing action. When the user detaches the overcap (105) to use the brush (212), the axial portion (216) of the brush (200) passes through the through hole (138) of the container packing (130), and the wiper (136) wipes off the second content stuck on the outer surface of the axial portion (216), thereby reducing the possibility of the second content contaminating surrounding objects due to the user's carelessness.

Meanwhile, in the cosmetic container (300) according to the first embodiment, the first container (125) and the second container (220) can be strongly sealed without unnecessary increase in volume, and the possibility of the first and/or second contents contaminating surrounding objects due to leakage can be reduced.

FIG. 6 is a cross-sectional view illustrating a cosmetic container (500) according to a second embodiment of the present invention. FIGS. 7, 8, and 9 are cross-sectional views illustrating an overcap (105), a sole (200), and a container packing (130) of the cosmetic container (500) illustrated in FIG. 6, respectively. The cosmetic container (500) according to the second embodiment of the present invention has many commonalities with the cosmetic container (300) according to the first embodiment described above, and the following description will focus on differences between the cosmetic container (500) according to the second embodiment. Features described with respect to the first embodiment can be applied to the second embodiment, and likewise, features described with respect to the second embodiment can be applied to the first embodiment. Some reference numbers mentioned in describing the second embodiment are intended to refer to components corresponding to the components to which the corresponding reference numbers were applied in the first embodiment.

Similar to the cosmetic container (300) according to the first embodiment described above, in the cosmetic container (500) according to the present embodiment, when the upper first container (125) is pressurized downward, the first content (not shown) injected into the interior of the first container (125) is injected into the interior of the second container (220) through the plunger (200) by the pump module (140). The interior of the second container (220) is filled with the second content, and the second content can be used by being mixed and diluted with the injected first content.

However, when the user discharges the first content inside the first container (125) into the second container (220) while the second container (220) is tightly sealed, the internal pressure of the second container (220) increases accordingly. This may cause the second content inside the second container (220) to be discharged to the outside when the user withdraws the plunger (200) to use the second content or at other unintended times. The cosmetic container (500) according to the second embodiment of the present invention may be designed with a structure that prevents this phenomenon.

A cosmetic container (500) according to a second embodiment of the present invention may include an overcap (105), a first container (125), a container packing (130), a pump module (140), a first elastic member (158), a stem (200), a second container (220), and a second elastic member (258). As one of the differences from the cosmetic container (300) according to the first embodiment, the cosmetic container (500) according to the second embodiment may include, in addition to the first elastic member (158) for operating the pump module (140), a second elastic member (258) for supporting the stem (200) so as to be relatively movable with respect to the overcap (105).

By the elastic support of the second elastic member (258), the sole (200) can be configured to be relatively movable with respect to the overcap (105) between a first position and a second position. The first position can be, for example, a position corresponding to a state in which the second elastic member (258) is less deformed or not deformed, and the second position can be, for example, a position corresponding to a state in which the second elastic member (258) is more deformed. That is, the degree of elastic deformation of the second elastic member (258) at the second position can be greater than the degree of elastic deformation of the second elastic member (258) at the first position.

Referring to Fig. 7, in addition to the aforementioned components, a catch (199) may be further formed on the overcap (105) of the cosmetic container (500) according to the second embodiment of the present invention. The catch (199) is a portion whose inner diameter is reduced on the inner side of the side wall (116) of the overcap (105), and the inner diameter may be formed to be smaller at the lower portion of the catch (199) than at the upper portion of the catch (199).

The catch (199) can be formed at a position between the catch projection (192) and the support projection (194), and can be formed at a position corresponding to the lower surface of the flange (209; see FIG. 8) formed on the screw head (202) when the screw (200) is in the second position. In the present embodiment, the screw (200) is relatively movably coupled to the overcap (105), and the catch projection (192) can restrict the flange (209) of the screw head (202) from the upper side when the screw (200) is in the first position, and the catch projection (199) can restrict the flange (209) of the screw head (202) from the lower side when the screw (200) is in the second position.

In FIG. 3, an example is shown in which the catch (192) of the overcap (105) is formed in the form of a band that crosses the entire inner surface of the overcap (105), but in some embodiments, the catch (192) may be formed in the form of a discontinuously formed protrusion as in FIG. 7. In the illustrated example, when the flange (209) of the solder head (202) is configured in the form of a continuously formed band, forming the catch (192) in an discontinuous form can make it easier to couple the solder (200). Of course, in some embodiments, the catch (192) may be formed in a continuous form and the flange (209) of the solder head (202) may be configured in the form of an discontinuous protrusion.

In the cosmetic container (500) of the present embodiment, the support protrusion (194) of the overcap (105) can be formed to be in close contact with the expanded portion (214) of the sole body (218). That is, the through hole (193) inside the support protrusion (194) can be formed so that its inner diameter corresponds to the outer diameter of the expanded portion (214) of the sole body (218), and the support protrusion (194) can be configured to completely block the flow of gas and liquid in a portion other than the through hole (193).

Referring to FIG. 8, the brush (200) of the cosmetic container (500) according to the second embodiment of the present invention may be composed of a brush head (202) and a brush body (218) similar to the brush (200) of the first embodiment.

The solder head (202) may have a hollow cylindrical shape open to the top and may include an outer circumferential surface (204) and a flat portion (205), and a flange (209) may be formed on the outer side of the outer circumferential surface. As described above, the solder head (200) may move between a first position and a second position due to the second elastic member (258), and the flange (209) may move correspondingly between the catch projection (192) and the catch step (199).

The solder body (218) may include an expanding portion (214) and a diametral portion (216). In the present embodiment, the outer diameter of the expanding portion (214) may be configured to correspond to the inner diameter of the through hole (193) of the overcap (105) and at the same time correspond to the inner diameter of the packing body (134; see FIG. 9) of the container packing (130). In addition, the diametral portion (216) of the solder body (218) may have an outer diameter corresponding to the inner diameter of the through hole (138) of the container packing (130) as in the first embodiment described above. When the solder (200) is in the first position, that is, when no external force is applied to the first container (125), the expanded portion (214) of the solder body (218) is in close contact with the through hole (193) of the overcap (105) and the inner surface of the container packing (130), and the reduced diameter portion (216) is in close contact with the through hole (138) of the container packing (130), thereby further increasing the watertightness of the second container (220).

Meanwhile, a ventilation groove (215) may be formed on the upper portion of the expanded portion (214). The ventilation groove (215) corresponds to a groove formed on the outer surface of the expanded portion (214) and may extend a predetermined length along the longitudinal direction of the expanded portion (214). The ventilation groove (215) may be formed at a position corresponding to the through hole (193) of the overcap (105) when the sole (200) moves relative to the overcap (105) and is in the second position. Therefore, when the sole (200) moves to the second position, the ventilation groove (215) moves to a position corresponding to the through hole (193), and the expanded portion (214) of the sole body (218) may no longer seal the through hole (193). In this state, air inside the second container (220) can be exhausted to the receiving space (115) through the ventilation groove (215) and the through hole (193).

Similarly, a ventilation groove (217) may be formed on the upper portion of the axial portion (216). The ventilation groove (217) corresponds to a groove formed on the outer surface of the axial portion (216) and may extend a predetermined length along the longitudinal direction of the axial portion (216). The ventilation groove (217) may be formed at a position corresponding to the through hole (138) of the container packing (130) when the sole (200) moves relative to the overcap (105) and is at a second position. Therefore, when the sole (200) moves to the second position, the ventilation groove (217) moves to a position corresponding to the through hole (138), and the axial portion (216) of the sole body (218) may no longer seal the through hole (138). In this state, air inside the second container (220) can be exhausted into the interior of the container packing (130) through the ventilation groove (217) and the through hole (138).

Referring to FIG. 9, the container packing (130) of the cosmetic container (500) according to the second embodiment of the present invention may include a flange (132), a packing body (134), and a wiper (136), which may be similar to the components of the container packing (130) described in relation to the first embodiment of the present invention. The container packing (130) may be manufactured from a more flexible material (e.g., PE) than other parts of the cosmetic container (500), and may exhibit a slight elastic deformation when pressurized to provide a strong sealing function.

A sealing projection (133) may be formed on the flange (132) of the container packing (130). The sealing projection (133) may protrude upward from the upper surface of the flange (132) and may be continuously formed along the flange (132) to have an annular shape. When the overcap (105) is coupled to the neck portion (222) of the second container (220), the support projection (194) and the upper portion of the second container (220) press the flange (132) located therebetween. At this time, the sealing projection (133) may be more easily deformed due to its small size, and the space between the overcap (105) and the container packing (130) may be sealed without a gap.

A sealing projection (135) may also be formed on the packing body (134) of the container packing (130). The sealing projection (135) may be continuously formed along the inner surface of the packing body (134) and may have an annular shape. The expanded portion (214) of the sealing member (200) may have an outer diameter corresponding to the inner diameter of the packing body (134), and the sealing projection (135) may further protrude into the inner side of the packing body (134). The sealing projection (135) may be more easily deformed due to its small size, and may seal the space between the packing body (134) and the expanded portion (214) without a gap within a range that does not impede the movement of the sealing member (200) when the sealing member (200) is in the first position.

A sealing protrusion (137) may also be formed on the wiper (136) of the container packing (130). The sealing protrusion (137) may be continuously formed along the inner surface of the through hole (138) at the lower end of the wiper (136) and may have an annular shape. The axial reduction portion (216) of the sealing member (200) may have an outer diameter corresponding to the inner diameter of the through hole (138), and the sealing protrusion (137) may further protrude into the inner side of the through hole (138). The sealing protrusion (137) may be more easily deformed due to its small size, and may seal the space between the wiper (136) and the axial reduction portion (216) without a gap within a range that does not impede the movement of the sealing member (200) when the sealing member (200) is in the first position.

Meanwhile, a sealing protrusion (139) may be formed at another location of the packing body (134) of the container packing (130). The sealing protrusion (139) may be formed continuously along the outer surface of the packing body (134) and may have an annular shape. The packing body (134) of the container packing (130) may have an outer diameter corresponding to the inner diameter of the neck portion (222) of the second container (220), and the sealing protrusion (139) may further protrude toward the outside of the packing body (134). The sealing protrusion (139) may be more easily deformed due to its small size, and may seal the space between the packing body (134) and the neck portion (222) without a gap.

The sealing protrusions (133, 135, 137, 139) formed on the container packing (130) can seal the space between the container packing (130) and other members that come into contact with the container packing (130). The sealing protrusions (133, 135, 137, 139) can improve the function of the container packing (130) to prevent the second contents inside the second container (220) from unintentionally leaking to the outside.

As described above, in the cosmetic container (500) according to the second embodiment of the present invention, the sole (200) may be configured to be movable to a first position and a second position within the receiving space (115) of the overcap (105), and a second elastic member (258) may be provided for this purpose.

The second elastic member (258) may be arranged, for example, between the lower surface of the sole head (202) and the support protrusion (194). In this case, considering the narrow space, the second elastic member (258) may be a coil spring having a truncated cone shape, etc. Of course, the shape and position of the second elastic member (258) may be set in various ways.

When no external force is applied to the first container (125), the second elastic member (258) may be in a state of not being deformed or being slightly deformed, and the stand (200) may be placed at the first position by the second elastic member (258). When an external force is applied to the first container (125) and the second elastic member (258) is deformed, the second elastic member (258) is compressed and the stand (200) may be lowered and placed at the second position.

Hereinafter, the operation of the cosmetic container (500) according to the second embodiment of the present invention will be described in more detail with reference to FIGS. 10 to 12. FIG. 10 is a cross-sectional view showing a part of the cosmetic container (500) illustrated in FIG. 6, illustrating a state before an external force is applied, FIG. 11 illustrates a state in which an external force is first applied to the cosmetic container (500), and FIG. 12 illustrates a state in which an external force is further applied to the cosmetic container (500).

In the state illustrated in Fig. 10, no external force has been applied to the cosmetic container (500), and both the first elastic member (158) and the second elastic member (258) are not deformed or are slightly deformed. The first elastic member (158) supports the assembly of the first container (125), the housing cover (145), and the housing (155) so that the upper portion of the first container (125) is exposed to the open area (114) of the overcap (105), and the second elastic member (258) supports the solder head (200) at the first position so that the flange (209) of the solder head (202) contacts the catch (192).

Since the packing body (134) of the container packing (130) has an outer diameter corresponding to the inner diameter of the neck portion (222) of the second container (220), the flange (132) of the container packing (130) is pressed between the upper portion of the second container (220) and the support protrusion (194), and sealing protrusions (133, 139) are formed on the outer surface of the packing body (134) and the upper surface of the flange (132), the container packing (130) can seal the second container (220). In addition, when the sealing member (200) is in the first position, the axial portion (216) of the sealing member (200) is in close contact with the sealing projection (137) around the through hole (138), and the expanded portion (214) of the sealing member (200) is in close contact with the sealing projection (135) on the inner surface of the packing body (134), so that a strong seal can be formed around the sealing member (200).

In this way, on the side of the first container (125) and the pump module (140), the first container (125) can be completely sealed by the structure of the neck portion (121), the housing cover (145), and the sealing member (149) of the first container (125), and on the side of the second container (220), the second container (220) can be completely sealed by the structure of the overcap (105), the container packing (130), and the sole (200).

When the first content of the first container (125) is discharged into the second container (220) while the second container (220) is completely sealed in this manner, there is a risk that the pressure inside the second container (220) will become excessively high and the second content will be ejected when the solder (200) is withdrawn. Therefore, the cosmetic container (500) according to the second embodiment of the present invention can maintain the pressure inside the second container (220) at an appropriate level by allowing ventilation of the second container (220) before the first content is discharged into the second container (220) by the pump module (140).

In the state illustrated in Fig. 11, an external force is first applied to the cosmetic container (500) and the first container (125) is slightly lowered. This may be achieved, for example, by the user pressuring downward the upper portion of the first container (125) exposed to the open area (114) of the overcap (105). This slight lowering of the first container (125) is due to elastic deformation of the second elastic member (258), and is a phenomenon that occurs because the sole (200) itself is lowered. That is, when an external force is first applied, the first elastic member (158) may not be deformed or may be only slightly deformed, whereas the second elastic member (258) may be completely elastically deformed to move the sole (200) from the first position to the second position. The sole (200) may be lowered until the flange (209) of the sole head (202) contacts the catch (199).

The second elastic member (258) may be set to have a lower elastic coefficient than the elastic coefficient of the first elastic member (158) so that the second elastic member (258) deforms earlier and more than the first elastic member (158). However, even if the first elastic member (158) and the second elastic member (258) have similar elastic coefficients, it can be expected that the second elastic member (258) will deform earlier due to the high pressure within the pump module (140) and the second container (220).

As shown in Fig. 11, when the screw (200) is lowered to the second position, the ventilation groove (217) formed in the axial portion (216) of the screw body (218) is positioned on the sealing projection (137) of the wiper (136), so that a gap is created between the wiper (136) and the screw body (218). The sealing projection (137) no longer provides a seal, and the air inside the second container (220) can move to the space inside the container packing (130) through the ventilation groove (217).

Likewise, when the solder (200) is lowered to the second position, the ventilation groove (215) formed in the enlarged portion (214) of the solder body (218) is positioned on the sealing projection (135) of the packing body (134), so that a gap is created between the packing body (134) and the solder body (218). That is, the sealing projection (135) no longer provides a seal, and air in the inner space of the container packing (130) can move to the upper portion of the support projection (194) through the ventilation groove (215).

In this way, air inside the second container (220) can move to the inner space of the container packing (130) through the ventilation groove (217), and air inside the container packing (130) can move to the upper part of the support protrusion (194) through the ventilation groove (215), and in the receiving space (115) above the support protrusion (194), the solder head (202), the pump module (140), and the first container (125) are not sealed to the side wall (116) of the overcap (105), so that air inside the second container (220) can be discharged to the outside, and the pressure inside the second container (220) can be lowered to an appropriate level.

In the state illustrated in Fig. 12, an external force is further applied to the cosmetic container (500) so that the first container (125) is lowered further. This corresponds to, for example, a case where the user further presses the upper portion of the first container (125) to discharge the first content into the second container (220). Of course, when the user presses the upper portion of the first container (125), the user will generally not be conscious of distinguishing between the deformation of the second elastic member (258) and the deformation of the first elastic member (158), and will only intend to discharge the first content. However, prior to the operation of discharging the first content, the aforementioned ventilation operation of the second container (220) will be performed even if the user is not conscious of it.

When the first container (125) is further pressed while the second elastic member (258) is already elastically deformed, the pump module (140) can operate while the first elastic member (158) is elastically deformed. That is, as exemplified in the above description of the first embodiment, the pump module (140) can discharge the first content that has been introduced into the housing (155) into the second container (220) through the movement passage (176, 184) and the discharge passage (208). At this time, the solder (200) has already moved to the second position, and the air inside the second container (220) can be exhausted to the outside by the ventilation groove (215, 217), so even if the first content is discharged into the second container (220), the pressure inside the second container (220) does not increase.

When the user removes the force applied to the first container (125), the first and second elastic members (158, 258) can return to their original positions, and the first content can be replenished inside the housing (155). The user can then separate the overcap (105) from the second container (220), and apply the second content diluted by the first content to a required area using the brush (212). When the overcap (105) is separated, the axial portion (216) of the sole (200) passes through the wiper (136), and the second content adhered to the surface of the axial portion (216) can be removed by the wiper (136).

According to the second embodiment of the present invention described above, the first container (125) containing the first content and the second container (220) containing the second content are strongly sealed to prevent leakage of the content while maintaining the pressure inside the second container at an appropriate level. In particular, even if the first container (125) is pressurized for the operation of the pump module (140), the phenomenon of the second content being ejected to the outside due to an increase in the pressure inside the second container (220) can be prevented.

Fig. 13 is a cross-sectional view illustrating a cosmetic container (700) according to a third embodiment of the present invention, and Figs. 14 and 15 are a cross-sectional view and an exploded perspective view, respectively, of the cosmetic container (700). Fig. 16 is a drawing illustrating a housing cover (145) of the cosmetic container (700), and Fig. 17 is a drawing illustrating a sole (200) of the cosmetic container (700). For reference, some components, including elastic members (158, 258), are omitted in Fig. 14.

The cosmetic container (700) according to the third embodiment of the present invention has many commonalities with the cosmetic containers (300, 500) according to the first and second embodiments described above, and the following description will focus on the differences of the cosmetic container (700) according to the third embodiment. The features described in relation to the first and second embodiments may be applied to the third embodiment, and likewise, the features described in relation to the third embodiment may be applied to the first or second embodiment. Some of the reference numbers mentioned in describing the third embodiment are intended to refer to components corresponding to the components to which the corresponding reference numbers are applied in the first and second embodiments.

Referring to FIGS. 13 to 17, a cosmetic container (700) according to a third embodiment of the present invention may include an overcap (105), a first container (125), a container packing (130), a pump module (140), a sole (200), and a second container (220).

Similar to the cosmetic containers (300, 500) according to the first and second embodiments described above, in the cosmetic container (700) according to the present embodiment, when the first container (125) at the top is pressurized downward, the first content (not shown) injected into the inside of the first container (125) can be discharged from the discharge hole (210) of the brush body (200) by the pump module (140). However, the cosmetic containers (300, 500) according to the first and second embodiments are described as having the discharge hole (210) formed above the joining groove (213) for joining the brush (212), but as in the cosmetic container (700) according to the third embodiment, a passage communicating with the discharge passage (208) of the brush body (218) may be formed inside the brush (222), so that the discharge hole (210) may be formed at the end of the brush body (218). The axial portion (216) of the solder body (218) in which the discharge hole (210) is formed can be normally inserted and stored inside the second container (220), and when the user withdraws the solder (200), the second content (not shown) may be present in the solder body (218).

When the user presses downward on the first container (125) according to his/her choice, the first content is discharged through the discharge hole (210), allowing the user to use the first content and the second content together. As a combination of the first content and the second content, for example, a combination of lip color and lip gloss, a combination of concealer and blemish essence, a combination of concealer with different tones, etc. can be used. Of course, as described above, there is no limitation on the type, nature, and use of the first content and the second content.

One of the major differences from the cosmetic containers (300, 500) according to the first and second embodiments is that the cosmetic container (700) according to the third embodiment can prevent the pump module (140) from operating even if the first container (125) is pressurized according to the user's choice. To this end, in the present embodiment, a coupling part that interlocks with each other may be provided on each of the housing cover (145) and the sole head (202).

Referring to FIGS. 16 and 17, the housing cover (145) may include a guide groove (250) as a first connecting portion, and the screw head (202) may include a guide protrusion (260) as a second connecting portion. When the guide groove (250) and the guide protrusion (260) are aligned with each other, the housing cover (145) and the screw head (202) can move relative to each other in the up-and-down direction as the guide protrusion (260) passes through the guide groove (250), and when the guide groove (250) and the guide protrusion (260) are not aligned with each other, there is no space for the guide protrusion (260) to pass through the guide groove (250), and thus the housing cover (145) and the screw head (202) cannot move in the up-and-down direction.

First, referring to FIG. 17, one or more guide protrusions (260) may be formed as a joint portion on the screw head (202). The guide protrusions (260) may protrude inwardly from the inner surface of the outer peripheral surface (204) of the screw head (202) and may be formed to have a width that allows them to pass through the guide grooves (250) of the housing cover (145). In FIG. 17, the guide protrusions (260) are formed in a shape that extends in the vertical direction, which allows the guide protrusions (260) to have higher structural strength and to maintain more stable joints when inserted into the vertical guide grooves (252) that are part of the guide grooves (250). Of course, the guide protrusions (260) do not necessarily have to have a shape that extends in the vertical direction, and in some embodiments, they may be implemented as point-shaped protrusions that protrude inwardly from one point.

Meanwhile, the enlarged portion (214) of the screw body (218) may further include a catch (264). When the screw (200) is coupled to the overcap (105), the catch (264) may be positioned below the support protrusion (194). The catch (264) may be caught on the lower portion of the support protrusion (194) to limit the position of the screw (200) in the up-down direction within the overcap (105). Although not shown in the drawing, the catch (264) may also serve to prevent relative rotation of the screw (200) with respect to the overcap (105). That is, the lower portion of the support protrusion (194) may have a structure that restrains each catch (264) on both sides.

The overcap (105) and the sole (200) may include other components in addition to or instead of the catch (264) to prevent relative rotation of the sole (200) with respect to the overcap (105). Similarly, although not shown in the drawings, the first container (125) and the pump module (140) may further include components to prevent relative rotation of the first container (125) with respect to the housing cover (145) of the pump module (140).

Referring to FIG. 16, one or more guide grooves (250) may be formed as a joining part in the housing cover (145). In the present embodiment, the housing cover (145) may include a lower cylinder (240) that extends a predetermined length below the cover step (142), and the guide groove (250) may be formed in the lower cylinder (240). The outer diameter of the lower cylinder (240) may be configured to correspond to the inner diameter of the outer peripheral surface (204) of the solder head (202).

The guide groove (250) may include a vertical guide groove (252) and a horizontal guide groove (254). The vertical guide groove (252) may be formed along the upper and lower direction on the outer surface of the lower cylinder (240), and the horizontal guide groove (254) may be formed along the horizontal direction, that is, along the circumferential direction of the outer surface of the lower cylinder (240), while continuing from the end of the vertical guide groove (252).

If the guide protrusion (260) is implemented in a form extending in the up-down direction as in FIG. 16, it is preferable that the horizontal guide groove (252) be formed at the lowest end of the lower cylinder (240). In the example illustrated in FIG. 16, the horizontal guide groove (254) is formed at the lowest end of the lower cylinder (240), and the catch step (255) is formed on the upper side of the horizontal guide groove (254). As described above, the guide protrusion (260) does not necessarily have to have a shape extending in the up-down direction, and if the guide protrusion (260) is formed in the shape of a point, the horizontal guide groove (252) may be formed at a position other than the lowest end of the lower cylinder (240).

As described above, the sole (200) may be configured not to rotate relative to the overcap (105), and the housing cover (145) and the first container (125) coupled thereto may be configured to rotate relative to the overcap (105). In addition, in the cosmetic container (700) according to the present embodiment, the area where the first container (125) is exposed may be larger than in the cosmetic containers (300, 500) according to the first and second embodiments. For example, in the example illustrated in FIG. 13, the entire upper portion of the first container (125) is exposed to the outside. This may be viewed as an enlargement of the open area (114) of the overcap (105).

When discharge of the first content is not required, the outer diameter of the lower cylinder (240) corresponds to the inner diameter of the outer circumferential surface (204), and the entire guide projection (260) (when the guide projection (260) has a dot shape) or the upper portion of the guide projection (260) (when the guide projection (260) has a straight shape extending in the vertical direction) is positioned within the horizontal guide groove (254), so that the lowermost end of the lower cylinder (240) is inserted into the inner side of the outer circumferential surface (204) of the solder head (202). At this time, the upper end of the guide projection (260) can contact the engaging step (255) on the upper side of the horizontal guide groove (254). Accordingly, even if the user presses down the first container (125), the guide protrusion (260) is caught on the catch (255), preventing the housing cover (145) and the first container (125) from moving down. Since the housing cover (145) cannot move down, the pump module (140) cannot operate, and the first contents (not shown) cannot be discharged through the discharge hole (210).

When discharge of the first content is required, the user can rotate the first container (125) by gripping a portion of the first container (125) exposed above the overcap (105). The first container (125) and the pump module (140) may include a component for preventing relative rotation of the first container (125) with respect to the housing cover (145), so that when the first container (125) is rotated, the housing cover (145) may be rotated together. Meanwhile, the overcap (105) and the screw head (200) may include a component for preventing relative rotation of the screw head (202) with respect to the overcap (105). Accordingly, the user can rotate the housing cover (145) relative to the screw head (202) in this way so that the guide protrusion (260) moves to a first angle aligned with the vertical guide groove (252), at which time the downward pressurization of the first container (125) and the operation of the pump module (140) become possible. That is, when the first container (125) is pressurized downward when the guide protrusion (260) is at the first angle, the housing cover (145) can move downward toward the screw head (202) as the guide protrusion (260) passes through the vertical guide groove (252). This operates the pump module (140), and the first content inside the housing (155) can be discharged through the discharge passage (208) into the discharge hole (210).

When the user no longer wants to discharge the first contents, the first container (125) can be rotated again to a position where the guide projection (260) is not aligned with the vertical guide groove (252). The rotatable range of the first container (125) can correspond to the length of the horizontal guide groove (254). Of course, in some embodiments, the horizontal guide groove (254) may be omitted and the guide groove (250) may include only the vertical guide groove (252).

Referring to FIG. 16, the joint portion of the housing cover (145) may further include a catch portion (257, 259) formed within the horizontal guide groove (254). The catch portion (257, 259) may correspond, for example, to a portion of the horizontal guide groove (254) at which the depth is reduced at that location. That is, the guide projection (260) and the horizontal guide groove (254) may be configured so that it is more difficult for the guide projection (260) to pass through the catch portion (257, 259) than for it to pass through the remaining portion of the horizontal guide groove (254).

One of the catches (257) may be formed at a position adjacent to the vertical guide groove (252). Accordingly, when the user rotates the first container (125) to move the guide protrusion (260) at a first angle, the user may detect a tactile sensation and sound of the guide protrusion (260) passing over the catche (257) and/or a difference in force required to pass through the catche (257) to determine whether the guide protrusion (260) is aligned with the vertical guide groove (252). The catche (257) may also serve to prevent the guide protrusion (260) from unintentionally being separated from the vertical guide groove (252) after moving at the first angle and entering the vertical guide groove (252).

In addition to a position adjacent to the vertical guide groove (252), one or more catches (259) may be formed in the horizontal guide groove (254). For example, in the example illustrated in FIG. 16, a catch (259) is also formed in a position adjacent to an opposite end of the horizontal guide groove (254) that is not connected to the vertical guide groove (252). In this case, when the user rotates the first container (125) so that the guide protrusion (260) moves to a second angle as far as possible from the vertical guide groove (252), the user can sense the tactile sensation and sound of the guide protrusion (260) passing over the catch (259) and/or the difference in force required to pass through the catch (259). In some embodiments, a plurality of catches (259) may be formed at equal intervals within the horizontal guide groove (254) so that the user can sense a click sensation when rotating the first container (125).

In FIGS. 15 to 17, examples are shown in which the housing cover (145) includes a guide groove (250) as a first connecting portion and the screw head (202) includes a guide projection (260) as a second connecting portion. However, it will be understood by those skilled in the art that the positions of the guide groove (250) and the guide projection (260), which can be aligned and engaged with each other by relative rotation between the housing cover (145) and the screw head (202), may change. That is, in some embodiments not shown, the housing cover (145) may include a guide projection that protrudes outward from the outer peripheral surface of the housing cover (145) as a first connecting portion, and the screw head (202) may include a guide groove formed on the inner peripheral surface of the outer peripheral surface as a second connecting portion. Of course, in this case, the shapes of the guide groove and the guide projection may be different.

In addition, since the purpose of the above-described connecting portion is to enable or disable the pump module (140) depending on the user's selection, the guide groove and the guide projection do not necessarily have to be formed on the housing cover (145) and the screw head (202). For example, in some embodiments not shown, the guide projection (or guide groove) as the first connecting portion may be formed on the outer surface of at least one of the first container (125) and the housing cover (145), and the guide groove (or guide projection) as the second connecting portion may be formed on the inner surface of the overcap (105). Of course, in this case, the shapes of the guide groove and the guide projection may be different. When the second connecting portion is formed on the overcap (105), it is possible to omit a component that prevents relative rotation of the screw head (200) with respect to the overcap (105).

According to the third embodiment of the present invention described above, the user can selectively rotate the exposed portion of the first container (125) to selectively place the pump module (140) in an operable or inoperable state. When the pump module (140) is in an inoperable state, the guide protrusion (260) is not aligned with the vertical guide groove (252) and is caught on the catch (255), so that even if the user presses the first container (125), the first container (125) does not move downward. This provides the effect of reliably preventing the first contents from being discharged unintentionally due to the user's carelessness.

Although the present invention has been described above with reference to one embodiment, it will be understood by those skilled in the art that various modifications and changes can be made to the present invention without departing from the spirit and scope of the present invention as set forth in the claims below.
