Description
Contents container
[0001] The present invention relates to a contents container.
[0002] Traditionally, double containers consisting of an inner container for easy refilling of contents and an outer container to protect the inner container have been widely used as containers for containing contents such as creams or lotions.
[0003] However, these dual-container designs presented the inconvenience of having to remove the inner container from the outer container each time the inner container was replaced. Specifically, when the inner container was easily separated from the outer container, the bond between the two containers became loose, or when the bond between the inner and outer containers was strengthened, the inner container became difficult to separate.
[0004] The purpose of this application is to provide a contents container to solve the above problem.
[0005] The technical problems of the present application are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art from the description below.

[0035] Referring to FIGS. 1 to 4, the contents container (1000) may include an inner container (100); an outer container (200); and a stopper (300).
[0036] The inner container (100) can form an inner space to accommodate contents. Here, the contents may be liquid, gel, or powder cosmetics. For example, the contents may include lotion, milk lotion, moisturizing lotion, nourishing lotion, skin lotion, skin softener, skin toner, astringent, massage cream, nourishing cream, moisture cream, whitening essence, tone-up cream, UV blocking agent, sunscreen, sun milk, BB cream, base, foundation, CC cream, concealer, blusher, shading, eye cream, primer, ampoule, etc. However, the present invention is not limited thereto, and other formulations or types of cosmetics, medical contents, etc. may be applied.
[0037] In an embodiment, the inner container (100) may be a bottle container. However, it is not limited thereto, and may be formed in various shapes such as a tube, jar, or pouch.
[0038] In an embodiment, a first coupling portion (110) may be formed at the top of the inner container (100). Specifically, the first coupling portion (110) may be coupled with a stopper (300). Such coupling may be a screw coupling, and thus, the first coupling portion (110) may be formed with screw threads, and the stopper (300) may have screw threads corresponding to the first coupling portion (110). However, the present invention is not limited thereto.
[0039] In an embodiment, the inner container (100) may include a content member (120) forming an inner receiving space; and a support member (130) extending downward from the content member (120). While the support member (130) is shown as extending from a side wall of the content member (120), this is exemplary and may extend from the bottom of the content member (120).
[0040] In an embodiment, a spout portion may be positioned at the top of the content donor (120), and a first connecting portion (110) may be formed on the outside of the spout portion.
[0041] The outer container (200) can form an inner space to accommodate the inner container (100). At this time, the outer container (200) may be, for example, a bottle container. However, it is not limited thereto, and may be formed in various shapes such as a jar.
[0042] In an embodiment, a second coupling portion (210) may be formed at the top of the outer container (200). Specifically, the second coupling portion (210) may be coupled with a stopper (300). Such coupling may be a screw coupling, and thus, the second coupling portion (210) may be formed with screw threads, and the stopper (300) may be formed with screw threads corresponding to the first coupling portion (110). However, the present invention is not limited thereto.
[0043] In an embodiment, the outer container (200) may include an outer container portion (220) that forms an inner receiving space; and a support portion (230) that shields the lower end of the outer container portion (220). At this time, a spout portion may be positioned at the upper end of the outer container portion (220), and a second connecting portion (210) may be formed on the outside of the spout portion.
[0044] Although the outer container part (220) and the support part (230) are shown as being formed separately and then joined together, this is exemplary, and depending on the embodiment, the outer container part (220) and the support part (230) may be formed integrally, or at least some of them may be formed separately and then joined together.
[0045] In an embodiment, the outer container part (220) may include an outer wall (222) to which the support part (230) is coupled, and an inner wall (224) in contact with the upper surface of the support part (230). That is, the outer container part (220) may have a double sidewall structure. An insertion groove is formed on the inner side of the outer wall (222), and an insertion protrusion is formed on the outer side of the support part (230), so that the support part (230) can be fitted into the outer wall (222). However, the present invention is not limited to this coupling method. When the support part (230) is coupled to the outer wall (222), the inner wall (224) can be in contact with the support part (230), thereby adjusting the insertion depth of the support part (230). According to an embodiment, the inner wall (224) may be in contact with the inner container (100) (in particular, the content portion (120) and the support portion (130)) and thus may have a shape corresponding thereto.
[0046] The stopper (300) can be detachably coupled to the inner container (100) and the outer container (200), thereby opening and closing the inner container (100). The stopper (300) can be detachably coupled to the first coupling portion (110) and the second coupling portion (210) of the inner container (100). Specifically, when the contents are sealed, the stopper (300) is coupled to the first coupling portion (110) and the second coupling portion (210), and when the contents are opened, the stopper (300) can be separated from the first coupling portion (110) and the second coupling portion (210). For example, the stopper (300) may have screw threads formed on the inner surface, thereby being screw-coupled to the first coupling portion (110) and the second coupling portion (210). However, the present invention is not limited thereto.
[0047] In an embodiment, the first coupling portion (110) may be positioned above the second coupling portion (210). To this end, the inner container (100) may be accommodated within the outer container (200), and the upper end of the inner container (100) may be seated on the upper end of the outer container (200). The first coupling portion (110) may be positioned on the upper end (i.e., the spout) of the inner container (100) where it is seated, and the second coupling portion (210) may be positioned on the upper end (i.e., the spout) of the outer container (200).
[0048] The first coupling portion (110) being positioned above the second coupling portion (210) may include not only the entire first coupling portion (110) being positioned above the second coupling portion (210), but also a portion of the first coupling portion (110) being positioned above the second coupling portion (210). For example, at least a portion of the first coupling portion (110) may be positioned at a height corresponding to the second coupling portion (210) rather than above the second coupling portion (210). However, the present invention is not limited thereto.
[0049] In an embodiment, the first coupling portion (110) may be continuous with the second coupling portion (210). For example, the first coupling portion (110) and the second coupling portion (210) may be formed with screw threads, and the screw threads of the first coupling portion (110) may be continuous with the screw threads of the second coupling portion (210). Correspondingly, the plug (300) may have screw threads, and the screw threads of the plug (300) may be sequentially / continuously coupled or separated from the first coupling portion (110) and the second coupling portion (210).
[0050] Here, the first connecting portion (110) and the second connecting portion (210), particularly the threads, being continuous with each other, may include not only being physically connected without partial separation, but also being connected in a separated state. Such separation may be achieved at least partially within a range that does not cause excessive disconnection or a sense of incongruity during the connection or separation operation of the plug. However, the present invention is not limited thereto.
[0051] In an embodiment, the inner container (100) may include at least one first fixing member (140) on the lower side of the first coupling member (110), and the outer container (200) may include at least one second fixing member (240) on the inner side of the second coupling member (210). The engagement between the first fixing member (140) and the second fixing member (240) may allow the inner container (100) to be positionally aligned with respect to the outer container (200) and / or may prevent the inner container (100) from rotating relative to the outer container (200).
[0052] For example, the first fixing part (140) may be formed by recessing an area of a side surface of the inner container (100). Correspondingly, the second fixing part (240) may be formed by protruding an area of a side surface of the outer container (200) (e.g., the inner surface of the spout). The protruding second fixing part (240) may be inserted into the recessed first fixing part (140). However, the present invention is not limited thereto, and according to an embodiment, the first fixing part (140) may be formed by protruding and the second fixing part (240) may be formed by recessing.
[0053] In an embodiment, the inner container (100) has a first sealing portion (150) formed along the outer circumference, and the outer container (200) has a second sealing portion (250) formed along the inner circumference, wherein the first sealing portion (150) and the second sealing portion (250) can be in close contact with each other. By the close contact between the first sealing portion (150) and the second sealing portion (250), the inner container (100) can be stably positioned within the outer container (200) and can be prevented from shaking.
[0054] For example, the first contact portion (150) and the second contact portion (250) may be formed with corresponding inclined surfaces, but the present invention is not limited thereto.
[0055] In an embodiment, the first contact portion (150) may be positioned on the lower side of the first coupling portion (110) and / or the second contact portion (250) may be positioned on the inner side of the second coupling portion (210). Additionally / alternatively, the first fixing portion (140) may be formed in an area of the first contact portion (150) and / or the second fixing portion (240) may be formed in an area of the second contact portion (250).
[0056] In an embodiment, the inner container (100) may be provided with a third coupling portion (160) for coupling with the outer container (200), and correspondingly, the outer container (200) may be provided with a fourth coupling portion (260) for coupling with the third coupling portion (160).
[0057] For example, the third coupling portion (160) may have an insertion groove formed, and the fourth coupling portion (260) may have an insertion protrusion formed, so that the third coupling portion (160) and the fourth coupling portion (260) may be fitted and coupled to each other. However, the present invention is not limited to this type of coupling. Depending on the embodiment, the positions of the protrusions and grooves may be changed, or a fitting or hooking coupling between the protrusions may be achieved.
[0058] In an embodiment, the third coupling portion (160) may be formed on the support portion (130) of the inner container (100). In particular, the third coupling portion (160) may be formed toward the inside of the support portion (130). Correspondingly, the fourth coupling portion (260) may be formed on the support portion (230) of the outer container (200). In particular, the fourth coupling portion (260) may be formed toward the upper side. However, the present invention is not limited thereto.
[0059] The contents container (1000) illustrated in FIGS. 1 to 4 is exemplary, and various configurations may be applied depending on the embodiment to which the present application is applied.

[0061] FIG. 5 is a perspective view of an inner container and an outer container according to an embodiment of the present application, and FIG. 6 is a front view of an inner container and an outer container according to an embodiment of the present application.
[0062] As shown, the first coupling portion (110) and the second coupling portion (210) may be formed with screw threads. At this time, the first coupling portion (110) is positioned above the second coupling portion (210), and the screw threads of the first coupling portion (110) may be continuous with the screw threads of the second coupling portion (210). Therefore, the plug (300) may be sequentially / continuously coupled with the screw threads of the first coupling portion (110) and the screw threads of the second coupling portion (210) simply by having corresponding screw threads.
[0063] The inner container (100) and outer container (200) illustrated in FIGS. 5 and 6 are exemplary, and various configurations may be applied depending on the embodiment to which the present application is applied.
[0064]
[0065] FIG. 7 is a perspective view and an exploded view of an inner container set according to an embodiment of the present application.
[0066] The internal container (100') of Fig. 7 is described in the same manner as the internal container (100) of Figs. 1 to 6, and any duplicate description will be omitted below.
[0067] Referring to Fig. 7, the inner container set (2000) may include an inner container (100') and an inner stopper (400). After the user has used up all the contents of the content container (1000), the user can detach and open the inner stopper (400) from the inner container set (2000) to the inner container (100'), and then replace it with the inner container (100) of the content container (1000).
[0068] In an embodiment, the inner container set (2000) may be composed of multiple sets, each of which may contain the same or different contents.
[0069] The internal container set (2000) illustrated in FIG. 7 is exemplary, and various configurations may be applied depending on the embodiment to which the present application is applied.
