Description

Airtight container with improved sealing power

[0001] The present invention relates to an airtight contents container with improved sealing power, and more particularly, to a contents container in which air located in an inner space of a contents container moves through a space provided in a cap so that the cap can be easily and strongly connected to the container.

[0002] Stick-type cosmetics are designed so that the contents are contained in a dish positioned inside the inner container, and the outer container rotates so that at least a portion of the dish moves, exposing the contents outside the opening of the inner container. Because these cosmetics are lifted and removed from the inner container, they are prone to exposure to air. Therefore, it is crucial to provide a sealed structure to prevent drying and deterioration of the contents during storage.

[0003] Typically, these stick-type cosmetics are equipped with a cap that covers the opening of the container to maintain airtightness. However, with conventional caps, when the cap is attached to the container, the gap between the cap and the container allows air to pass through, which can reduce the airtightness of the container and cause oxidation of the contents. While some caps feature a silicone or rubber ring to enhance the sealing power, this can damage the ring over time, reducing the sealing power. Furthermore, if the sealing power of the cap is excessively high, internal pressure can be generated when the cap is attached to the container, potentially damaging the contents or preventing the cap from closing properly.

[0004] The present invention is intended to solve the above problems and aims to strengthen the airtightness of a contents container.

[0005] Furthermore, the present invention aims to provide a contents container in which the cap can be easily mounted when the cap is mounted on the container.

[0006] The technical problems of the present invention 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.

[0007] According to an embodiment of the present invention, a contents container is provided. The contents container comprises:

[0008] An inner space having an opening for accommodating contents is formed, an inner cap having a communication hole communicating with the inner space and detachably coupled to the inner cap, and an outer cap coupled to the inner cap, wherein an intermediate space is formed between the inner cap and the outer cap, and when the inner cap is moved from a first position covering the opening of the inner cap to a second position located closer to the inner cap than the first position, air located in the inner space is configured to move to the outside of the outer cap through the intermediate space.

[0009] According to the present invention, a space is formed between the outer cap and the inner cap of the contents container, and in the process of sealing the container with the cap, air moves to the outside through the space formed between the outer cap and the inner cap, thereby enhancing the airtightness of the container.

[0010] According to another embodiment of the present invention, a contents container has the advantage of excellent sealing power due to the reinforced sealing structure between the inner cap and the contents container, the inner cap and the outer cap, and the contents container and the outer container.

[0011] The contents container according to the present invention has excellent airtightness and sealing power, and it is very easy to attach a cap to the container.

[0012] According to another embodiment of the present invention, by including a flue hole cover portion that covers the flue hole, the interior can be prevented from being exposed through the flue hole. Accordingly, even if the container is made of a transparent material, a neat and luxurious appearance can be achieved.

[0020] Figure 7 is a cross-sectional view according to another embodiment of the present invention.

[0021] According to an embodiment of the present invention, a contents container is provided. The contents container comprises:

[0022] A container having an inner space having an opening for accommodating contents, a communication hole communicating with the inner space is formed, an inner cap detachably coupled to the container, and an outer cap coupled to the inner cap, an intermediate space is formed between the inner cap and the outer cap, and when the inner cap is moved from a first position covering the opening of the container to a second position located closer to the container than the first position, air located in the inner space is configured to move to the outside of the outer cap through the intermediate space.

[0023] The pressure in the inner space can correspond to the pressure outside the outer cap when the inner cap is in the second position.

[0024] The inner cap can form an air room communicating with the space between the inner cap and the outer cap and a communication hole.

[0025] The volume of the air room may be less than or equal to the changing volume of the space between the inner cap and the inner body while the inner cap is moved from the first position to the second position.

[0026] The outer cap includes an outer cap upper portion and an outer cap side portion extending downward from the outer cap upper portion, the inner cap includes an inner cap upper portion facing the outer cap upper portion and an inner cap side portion extending downward from the inner cap upper portion to face the outer cap side portion, and the air room can be located between the inner cap upper portion and the outer cap upper portion.

[0027] A flue hole may be formed on the upper part of the inner cap.

[0028] The outer cap may include an inner cap mounting portion that protrudes toward the inner cap to be coupled with the inner cap.

[0029] The inner cap may include an outer cap mounting portion that protrudes toward the outer cap to be supported by the inner cap mounting portion.

[0030] The outer cap mounting portion may be spaced apart from the inner cap mounting portion at a portion thereof so that air can pass between the outer cap mounting portion and the inner cap mounting portion while the inner cap is moved from the first position to the second position.

[0031] The inner cap includes an outer cap mounting portion that protrudes toward the outer cap, and the outer cap includes an air room forming portion that is configured to seal the space between the outer cap mounting portion by coming into close contact with the outer cap mounting portion, so that when the inner cap is mounted on the inner device, external air can be prevented from moving toward the inner space through the space between.

[0032] The inner cap may be configured to contact the inner space while in the second position to prevent air in the inner space from passing between the inner cap and the inner container, and may include a container support portion protruding toward the inner container.

[0033] The contents container may further include an outer container that is rotatably coupled to the contents device and configured to move the contents by rotation.

[0034] The contents container may further include a sealing member positioned between the outer container and the contents container to seal between the outer container and the contents container, and mounted on the contents container.

[0035] The inner cap may include a flue hole cover portion that covers the flue hole.

[0040] Fig. 1 is a perspective view of a contents container (1) according to an embodiment of the present invention. In particular, in Fig. 1, Fig. 1(a) is a perspective view illustrating a cap (CA) coupled to a container (CO). Fig. 1(b) is a perspective view illustrating a cap (CA) separated from the container (CO).

[0041] Referring to Fig. 1, a contents container (1) according to one embodiment of the present invention is described.

[0042] As illustrated in Fig. 1, a contents container (1) may be provided to accommodate and use contents. Here, the contents may be cosmetics, and for example, stick-type cosmetics, such as sun sticks, foundations, serums, lipsticks, lip balms, etc. However, the present invention is not limited thereto, and the spirit of the present invention may be applied to any contents that can be accommodated in the container (CO). The contents container (1) may have, for example, a cylindrical shape to correspond to the shape of the contents.

[0043] As illustrated in FIGS. 1(a) and 1(b), the contents container (1) may include a cap (CA) and a container (CO). The container (CO) may be configured to accommodate contents. The container (CO) may have an opening formed on one side through which contents may enter and exit. Through the opening of the container (CO), the contents may come into contact with air, and thus, the contents may be oxidized and lose their intended function. The cap (CA) may reduce or prevent the contents from coming into contact with air, thereby increasing the preservation properties of the contents.

[0044] More specifically, the container (CO) may include an outer container (300) positioned on the outside; and an inner container (400) positioned on the inside of the outer container (300). A portion of the inner container (400) may be exposed by extending upward from the outer container (300). The inner container (400) may be formed with an inner space (400S) having an opening to accommodate contents therein. The opening of the container (CO) mentioned above may be formed at an upper end of the inner space (400S). The cap (CA) may be configured to be coupled with the inner container (400) or the outer container (300) to prevent the contents from being oxidized by air.

[0045] Below, the configuration of the contents container (1) is described in more detail.

[0046] Fig. 2 is an exploded view of a contents container (1) according to an embodiment of the present invention. Fig. 3 is an exploded view of an inner container (400), an outer container (300), a sealing member (500), and a spiral (700) according to an embodiment of the present invention. In particular, Fig. 2 includes an enlarged view of an inner cap (200) as viewed from below, an enlarged view of an outer cap (100) as viewed from below, and an enlarged view of an inner container (400) as viewed from below. In particular, Fig. 3 includes an enlarged view of a spiral (700) as viewed from below, and an enlarged view of an outer container (300) as viewed from below.

[0047] Referring to FIGS. 2 and 3, the configuration of a contents container (1) according to one embodiment of the present invention will be described in more detail.

[0048] As illustrated in FIG. 2, the contents container (1) may include a cap (CA) including an inner cap (200) and an outer cap (100), a container (CO) including an inner container (400) and an outer container (300), a plate (600), a spiral (700), and / or a sealing member (500).

[0049] The inner cap (200) may be positioned on the inside of the outer cap (100). The outer cap (100) may be formed larger than the inner cap (200) to accommodate the inner cap (200). Accordingly, the outer cap (100) may prevent the inner cap (200) from being damaged from the outside. Since the inner cap (200) is configured to directly face the contents, it may be necessary to prevent damage. Furthermore, the outer cap (100) may be transparent or translucent. Accordingly, even if the outer cap (100) covers the inner cap (200), the inner cap (200) may be observed from the outside of the contents container (1). Accordingly, the aesthetic appeal of the cap (CA) may be improved. For reference, the outer cap (100) and the inner cap (200) may be made of a plastic material and may be formed by injection molding. For example, the outer cap (100) and the inner cap (200) may be formed by double injection. Additionally, as described below, since the cap (CA) includes the outer cap (100) and the inner cap (200), a space through which air can move may be formed between the outer cap (100) and the inner cap (200). This will be described in detail later along with related explanations.

[0050] The outer cap (100) may include an outer cap upper portion (110) and an outer cap side portion (120) extending downward from the outer cap upper portion (110). More specifically, the outer cap upper portion (110) may be approximately circular, as described above, so that the exterior of the contents container (1) may have a cylindrical shape. The outer cap side portion (120) may extend downward from an end of the outer cap upper portion (110). Accordingly, the outer cap (100) may have a cylindrical shape with an opening formed at the lower portion.

[0051] The inner cap (200) may be formed to correspond to the shape of the outer cap (100). More specifically, the inner cap (200) may include an inner cap upper portion (210) facing the outer cap upper portion (110) and an inner cap side portion (220) extending downward from the inner cap upper portion (210) to face the outer cap side portion (120). The inner cap upper portion (210) may be circular and smaller than the outer cap upper portion (110) to correspond to the outer cap upper portion (110). The inner cap side portion (220) may be positioned inward relative to the outer cap side portion (120). The inner cap side portion (220) may extend less downward than the outer cap side portion (120) so as to be covered by the outer cap side portion (120).

[0052] The inner cap (200) may be coupled to the outer cap (100). More specifically, the inner cap (200) may include an outer cap mounting portion (221) that protrudes toward the outer cap (100) adjacent to the inner cap upper portion (210). The outer cap mounting portion (221) may extend along the circumferential direction of the inner cap upper portion (210). The outer cap (100) may include an inner cap mounting portion (122) that protrudes toward the inner cap (200) so as to be coupled with the inner cap (200). The inner cap mounting portion (122) may extend along the circumferential direction of the outer cap upper portion (110). The inner cap mounting portion (122) may be provided at a position corresponding to the outer cap mounting portion (221). Accordingly, when the inner cap (200) is coupled to the outer cap (100), the outer cap mounting portion (221) can be supported by the inner cap mounting portion (122). More specifically, as illustrated in FIG. 4(b), the inner cap mounting portion (122) is positioned below the outer cap mounting portion (221), thereby preventing the inner cap (200) from being separated from the outer cap (100) through the lower opening of the outer cap (100). However, as described below, since air needs to move between the inner cap (200) and the outer cap (100), the inner cap mounting portion (122) and the outer cap mounting portion (221) can form a gap and come into contact with each other.

[0053] The inner cap (200) may include a container support portion (222) that protrudes toward the container (CO) to seal the container (CO). More specifically, as illustrated in FIG. 4(b), the inner cap (200) may include a container support portion (222) that is configured to contact the container (400) to prevent air in the inner space (400S) from passing between the inner cap (200) and the container (400). The container support portion (222) may protrude toward the container (400). The container support portion (222) may protrude inward from the inner cap side portion (220). The container support portion (222) may extend along the circumference of the inner cap (200). Accordingly, the container support portion (222) may contact the entire outer circumference of the container (400). Since the container support (222) is in contact with the entire outer circumference, air can be prevented from passing between the inner cap (200) and the contents (400) and oxidizing the contents.

[0054] For reference, the inner cap side portion (220) located on the lower side of the container support portion (222) may be spaced apart from the inner container (400) by at least a portion to reduce friction with the inner container (400).

[0055] The outer cap (100) may include a container mounting rib (123) that protrudes toward the container (CO) so as to be mounted on the container (CO). The container mounting rib (123) may extend along the circumferential direction of the outer cap (100). More specifically, as illustrated in FIG. 4(b), the container mounting rib (123) may contact the outer container (300). The outer container (300) may include a cap mounting rib (320) that protrudes toward the cap (CA) so as to correspond to the container mounting rib (123). When the cap (CA) is completely mounted on the container (CO), the cap mounting rib (320) may support the container mounting rib (123) from the upper side thereof. Accordingly, the outer cap (100) may be prevented from being separated from the upper side of the outer container (300). However, the container mounting rib (123) and the cap mounting rib (320) are joined by a forced fit, so that when a force exceeding a preset value is applied to separate the cap (CA) from the container (CO), the cap (CA) can be separated from the container (CO). The user can use the contents when the cap (CA) is separated from the container (CO).

[0056] A plate (600) may be provided to support the contents. The plate (600) is accommodated inside the contents container (400) and can be raised or lowered to move the contents. For reference, the plate (600) may be made of a plastic material and may be formed by injection molding.

[0057] The plate (600) may include a contents mounting portion (610) on which contents are mounted and a plate screw portion (620) extending from the contents mounting portion (610).

[0058] The contents mounting portion (610) may have a concave space formed to mount contents. A rib extending vertically may be provided on the inside of the space of the contents mounting portion (610) to prevent separation of the contents.

[0059] The plate screw portion (620) may extend downward from the content mounting portion (610). Screw threads may be formed on the plate screw portion (620) to engage with the spiral screw threads (720) of the spiral (700) described later. Accordingly, when the spiral (700) rotates, the plate (600) may be raised or lowered so that the content moves according to the interaction between the spiral screw threads (720) and the screw threads of the plate screw portion (620). The plate screw portion (620) may have a smaller cross-sectional area than the content mounting portion (610). Accordingly, the plate screw portion (620) may pass through the guide hole (400H) of the content holder (400) described later, but the content mounting portion (610) may be prevented from passing through, so that the radius of movement of the plate (600) may be limited. More specifically, the lower surface of the contents mounting portion (610) may be supported by a part of the contents holder (400) forming a guide hole (400H), so that the radius of movement of the plate (600) may be limited.

[0060] The plate screw portion (620) may be formed with a D-cut that cuts the shape of a cylinder into a plane extending in the longitudinal direction. Accordingly, the shape of the guide hole (400H) described later may also correspond to the D-cut, so that the plate screw portion (620) may be configured to rotate together with the contents (400) so that the plate (600) rotates according to the rotation of the contents (400).

[0061] A spiral (700) may be provided to elevate a plate (600). As illustrated in FIG. 4, the spiral (700) may accommodate a plate screw portion (620). At least a portion of the spiral (700) may be accommodated in the inner member (400). The spiral (700) may be positioned at the lower side of a portion of the inner member (400) that forms the guide hole (400H), thereby restricting upward movement. For reference, the spiral (700) may be made of a plastic material and may be formed by injection molding.

[0062] The spiral (700) may include a spiral thread (720) that engages with the threads of the countersunk screw portion (620). The spiral thread (720) may protrude toward the countersunk screw portion (620). The spiral thread (720) may extend in the circumferential direction of the spiral (700).

[0063] As illustrated in FIG. 3, the spiral (700) may include a spiral engagement portion (710) that engages with the outer container (300) on the lower side. The spiral engagement portion (710) may protrude toward the outer container (300) and extend in a circumferential direction. As described below, the spiral engagement portion (710) may engage with a portion of the outer container (300) so that when the outer container (300) rotates, the spiral (700) rotates together.

[0064] A container (400) may be provided to accommodate contents. The container (400) may extend in the vertical direction surrounding the contents mounting portion (610) to guide the movement of the contents mounting portion (610) of the plate (600). The container (400) may have a cylindrical shape with an opening formed at the upper and / or lower sides. The container (400) may be rotatable with respect to the spiral (700). For reference, the container (400) may be made of a plastic material and may be formed by injection molding.

[0065] The content holder (400) may have a guide hole (400H) formed on the inside through which the plate screw portion (620) of the plate (600) passes. The role of the guide hole (400H) may be as described above.

[0066] The content member (400) may include a sealing member fixing portion (410) in which a groove is formed so that a sealing member (500) described later is fixed.

[0067] An outer container (300) may be provided to cover at least a portion of the contents (400) from the outside. The outer container (300) may accommodate the contents (400). The outer container (300) may be rotatably coupled to the contents (400). As described below, the outer container (300) may be configured to move contents accommodated in the contents (400) by rotation. For reference, the outer container (300) may be made of a plastic material and may be formed by injection molding.

[0068] The outer container (300) may include an outer container engagement portion (310) that protrudes toward the spiral (700) so as to rotate together with the spiral (700). More specifically, the outer container engagement portion (310) may engage with the spiral engagement portion (710) of the spiral (700). The outer container engagement portion (310) may protrude toward the spiral engagement portion (710). The outer container engagement portions (310) may be provided in multiple numbers and arranged in a circumferential direction. Accordingly, when the outer container engagement portion (310) rotates, it may come into contact with the spiral engagement portion (710), thereby causing the spiral (700) to rotate.

[0069] A sealing member (500) positioned between the outer container (300) and the inner container (400) may be provided to seal the space between the inner container (400) and the outer container (300). The sealing member (500) may be, for example, an adhesive, or the like, but may be an O-ring in one embodiment of the present invention. The sealing member (500) may be annular. The sealing member (500) may be mounted to the inner container (400). More specifically, the sealing member (500) may be positioned at the sealing member fixing portion (410) of the inner container (400). The sealing member (500) may seal the space between the inner container (400) and the outer container (300) to prevent air from entering between the inner container (400) and moving to the contents. For reference, the sealing member (500) may have a rubber material.

[0070] The operation of the configuration of the contents container (1) described above is described in more detail later in the description with reference to Fig. 6.

[0071] Below, the idea of ​​the present invention related to the movement of air located in the inner space (400S) while the cap (CA) is coupled to the container (CO) is explained.

[0072] Fig. 4 is a cross-sectional view according to an embodiment of the present invention. In particular, in Fig. 4, Fig. 4(a) is a cross-sectional view when the inner cap (200) is in a first position covering the opening of the inner container (400). Fig. 4(b) is a cross-sectional view when the inner cap (200) is in a second position, closer to the inner container (400) than the first position. Fig. 5 is an enlarged cross-sectional view according to an embodiment of the present invention. In particular, Fig. 5 is an enlarged cross-sectional view illustrating V of Fig. 4(b) in an enlarged manner.

[0073] Referring to FIGS. 4 and 5, the movement of air according to one embodiment of the present invention will be described.

[0074] As illustrated in FIG. 4, a space may be formed between the outer cap (100) and the inner cap (200). More specifically, an air room (110S) may be formed between the upper portion of the outer cap (110) and the upper portion of the inner cap (210). While the cap (CA) is being coupled to the container (CO), the air located in the upper portion of the inner space (400S) may be compressed. As the pressure increases when the air is compressed, it may become difficult to couple the cap (CA) to the container (CO). To prevent this, the air located in the inner space (400S) may be moved to the air room (110S) while the cap (CA) is being coupled to the container (CO). At this time, a communication hole (210H) may be formed in the inner cap (200). More specifically, the communication hole (210H) may be formed in the upper portion (210) of the inner cap. The communication hole (210H) is connected to the inner space (400S) and can be connected to the air room (110S). Air located in the inner space (400S) can move to the air room (110S) through the communication hole (210H) while the cap (CA) is connected to the container (CO), thereby preventing pressure from rising in the inner space (400S).

[0075] At this time, the inner cap (200) can be moved from a first position covering the opening of the inner container (400) to a second position that is closer to the inner container (400) than the first position. For example, the position of the inner cap (200) illustrated in FIG. 4(a) may be the first position, and the position of the inner cap (200) illustrated in FIG. 4(b) may be the second position. For example, when the inner cap (200) is in the second position, the container mounting rib (123) of the outer cap (100) mentioned above can be forcefully fitted with the cap mounting rib (320) of the outer container (300).

[0076] In particular, when the inner cap (200) is in the second position, as mentioned above, the container support (222) of the inner cap (200) and the outer surface of the inner container (400) are in contact to prevent air from penetrating between the inner cap (200) and the inner container (400), so that the air located in the inner space (400S) is prevented from moving between the inner cap (200) and the inner container (400), and thus a separate space for the air to move may be required to move the cap (CA).

[0077] At this time, the outer cap upper part (110) and the inner cap upper part (210) may be spaced apart so that an air room (110S) is formed. The outer cap (100) may include an air room forming part (121) that extends from the outer cap upper part (110) and comes into contact with the inner cap upper part (210). The air room forming part (121) may be positioned at a point where the outer cap upper part (110) and the outer cap side part (120) meet. The inner cap upper part (210) may be supported by the air room forming part (121) and may be prevented from moving to come into contact with the outer cap upper part (110). More specifically, the outer cap mounting part (221) may be positioned on the edge of the inner cap upper part (210). The air room forming part (121) may support the outer cap mounting part (221) on the upper side of the outer cap mounting part (221) of the inner cap (200). Accordingly, the outer cap mounting portion (221) of the inner cap (200) is positioned between the air room forming portion (121) and the inner cap mounting portion (122) to connect the inner cap (200) and the outer cap (100).

[0078] The air room forming part (121) may be configured to seal the interspace (220S) by coming into close contact with the outer cap mounting part (221) to prevent external air from moving toward the inner space (400S) through the interspace (220S) when the inner cap (200) is mounted on the inner container (400). Accordingly, when the inner cap (200) is mounted on the inner container (400), air may be prevented from coming into contact with the contents located in the inner space (400S), thereby helping to preserve the contents. However, sealing the space between the inner cap (200) and the outer cap (100) is not limited to being achieved only by the air room forming part (121) and the outer cap mounting part (221), but may also be achieved by contact with the outer cap mounting part (221) and the inner cap mounting part (122), or by contact with other parts of the outer cap (100).

[0079] Additionally, the contents container (1) can prevent oxidation of the contents by preventing the contents from coming into contact with air by the following three methods when the cap (CA) mentioned above is mounted on the container (CO). In other words, the contents container (1) can achieve a three-point seal that prevents the contents from coming into contact with air. The first may be the contact between the container support member (222) and the contents container (400). The second may be the contact by the air room forming member (121) and the outer cap mounting member (221). The third may be the contact between the sealing member (500) and the contents container (400).

[0080]

[0081] The outer cap (100) may be coupled to the inner cap (200) so that an interspace (220S) is formed between the outer cap (100) and the inner cap (200). Since air is introduced into the air room (110S) by the air moved to the air room (110S), the pressure of the air room (110S) may also increase. The air located in the air room (110S) may move to the outside of the cap (CA) through the interspace (220S). More specifically, the interspace (220S) may be formed between the outer cap side portion (120) and the inner cap side portion (220). While the inner cap (200) is moved from the first position to the second position, the air located in the inner space (400S) may move to the outside of the outer cap (100) through the interspace (220S).

[0082] At this time, a portion of the outer cap mounting portion (221) may be spaced apart from the inner cap mounting portion (122) so that air can pass between the outer cap mounting portion (221) and the inner cap mounting portion (122) while the inner cap (200) moves from the first position to the second position. For example, as illustrated in FIG. 2, the edge of the outer cap mounting portion (221) may form a polygon.

[0083] At this time, the pressure of the inner space (400S) may correspond to the pressure outside the outer cap (100) when the inner cap (200) is in the second position. Here, the meaning of the pressures corresponding may mean that the pressures are the same or similar. If the pressure of the inner space (400S) is lower than the pressure outside the cap (CA), it may be difficult to separate the cap (CA) from the container (CO). In the content container (1) according to one embodiment of the present invention, when the cap (CA) is combined with the container (CO), the pressure of the inner space (400S) and the pressure outside the cap (CA) may correspond, so that the separation of the cap (CA) from the container (CO) may not be hindered. It is preferable that the cap (CA) is combined to a degree that it is not accidentally separated from the container (CO), but even so, it may be preferable that the cap (CA) can be easily separated from the container (CO) when separating the cap (CA) from the container (CO) for use.

[0084] In other words, the inner cap (200) can form an air room (110S) that is connected to a communication hole (210H) and an interspace (220S) between the inner cap (200) and the outer cap (100). As shown by the arrows in Fig. 5, while the inner cap (200) moves from the first position to the second position, air can move from the inner space (400S) through the communication hole (210H) and the air room (110S) to the interspace (220S), and can move from the interspace (220S) to the outside of the cap (CA).

[0085] The volume of the air room (110S) may be less than or equal to the volume change of the space between the inner cap (200) and the inner container (400) while the inner cap (200) is moved from the first position to the second position. More specifically, the volume of the air room (110S) may be less than or equal to the volume change of the space between the inner cap (200) and the inner container (400) while the inner cap (200) is moved from a position where the container support part (222) of the inner cap (200) first contacts the inner container (400) to a position where the container mounting rib (123) of the outer cap (100) is forcibly fitted with the cap mounting rib (320) of the outer container (300). If the volumes are equal to each other, the air moved while the inner cap (200) is moved can be entirely accommodated in the air room (110S). If the volume of the air room (110S) is smaller than the change in volume of the space (220S) between the inner cap (200) and the inner container (400), some of the air moving in the inner space (400S) may move to the outside of the cap (CA) through the air room (110S) and the space (220S).

[0086] Additionally, in order to form the volume required for the air room (110S), the inner cap upper portion (210) may be formed so that a portion on the air room (110S) side is concave, and the outer cap upper portion (110) may be formed so that a portion on the air room (110S) side is concave. If the inner cap upper portion (210) and the outer cap upper portion (110) are spaced apart from each other greatly, the volume of the entire contents container (1) increases. Therefore, to prevent this, the outer cap upper portion (110) and the inner cap upper portion (210) are spaced apart from each other to a minimum, and the volume of the required air room (110S) may be formed in the same manner as mentioned above.

[0087] As mentioned above, when the outer cap (100) is transparent or translucent, the inner cap (200) can be observed from the outside of the cap (CA). At this time, the inner space (400S) can be observed through the communication hole (210H) formed in the inner cap (200). Since the inner space (400S) may provide an unsightly appearance due to the contents scattering as they move, it may be necessary to prevent the inner space (400S) from being exposed through the communication hole (210H). To this end, the inner cap (200) may include a communication hole cover portion (211) that covers the communication hole (210H). The communication hole cover portion (211) may extend from the upper portion (210) of the inner cap. More specifically, the communication hole cover portion (211) may extend from a portion adjacent to the communication hole (210H) of the upper portion (210) of the inner cap. The flue hole cover part (211) may extend downward from the inner cap upper part (210) and then be bent to extend in a direction covering the flue hole (210H). However, if the flue hole cover part (211) is extended too long, the air moving from the inner space (400S) toward the flue hole (210H) may be restricted from moving by the flue hole cover part (211). Therefore, it may be preferable for the flue hole cover part (211) to extend to correspond to the flue hole (210H).

[0088] Figure 6 is a usage state diagram according to an embodiment of the present invention.

[0089] Referring to FIG. 6, the use of contents according to one embodiment of the present invention is described.

[0090] As illustrated in FIG. 6, after the cap (CA) is separated from the container (CO), the contents can be operated to use the contents in the contents container (1). More specifically, when the outer container (300) is rotated with respect to the contents container (400), the contents move toward the opening of the inner space (400S) and are exposed to the outside of the contents container (1) through the opening of the inner space (400S), so that the user can use the contents. More specifically, as described above, the outer container (300) can be engaged with the spiral (700) and rotated together. When the outer container (300) is rotated, the spiral (700) can be rotated. The spiral (700) is engaged with the plate screw portion (620) of the plate (600), so that when the spiral (700) is rotated, the plate (600) can be raised and lowered. When the plate (600) is raised, the contents mounted on the plate (600) can be raised together and moved toward the opening of the inner space (400S).

[0091] After using the contents, the movement of the contents is understood to perform the opposite action to the above description.

[0092] Below, embodiments different from the above embodiments are described. Commonalities with the above embodiments will be omitted as much as possible, and the other embodiments will be described focusing on differences. In other words, it should be clear that any details not described in the other embodiments can be supplemented by the above embodiments.

[0093] Fig. 7 is a cross-sectional view according to another embodiment of the present invention. In particular, in Fig. 7, Fig. 7(a) is a cross-sectional view when the inner cap (200) is in a first position covering the opening of the inner container (400). Fig. 7(b) is a cross-sectional view when the inner cap (200) is in a second position, closer to the inner container (400) than the first position.

[0094] Referring to FIG. 7, a contents container (1) according to another embodiment of the present invention is described.

[0095] Another embodiment differs from the above-described embodiment in that there is no flue hole cover (211), the shapes of the inner cap mounting portion (122-1) and the outer cap mounting portion (221-1) and the container support portion (222-1) are different, and the shapes of the container mounting rib (123-1) and the cap mounting rib (320-1) are different.

[0096] The inner cap (200) may not include a flue hole cover (211). In this case, the outer cap (100) may be opaque or the height of the air room (110S) may be set high to prevent the flue hole (210H) from being exposed to the outside.

[0097] The inner cap (200) may include an inner cap side portion (220) extending from the inner cap upper portion (210). The inner cap (200) may include a container support portion (222-1) extending radially outward from the inner cap side portion (220). The container support portion (222-1) may protrude radially outward from the inner cap side portion (220) to form a step.

[0098] The air room forming portion (121-1) can be in contact with the side surface of the inner cap side portion (220) and the upper surface of the container support portion (222-1). In other words, the air room forming portion (121-1) can be accommodated in the step formed by the container support portion (222-1).

[0099] The lower surface of the container support member (222-1) can be in contact with the upper surface of the inner container (400). Accordingly, the space between the inner cap (200) and the inner container (400) can be sealed.

[0100] The inner cap (200) may include an outer cap mounting portion (221-1) extending from a container support portion (222-1). The outer cap (100) may include an inner cap mounting portion (122-1) protruding inwardly to support the outer cap mounting portion (221-1) from the lower side of the outer cap mounting portion (221-1). Accordingly, the outer cap mounting portion (221-1) may be supported from the upper side by the air room forming portion (121-1) and from the lower side by the inner cap mounting portion (122-1).

[0101] As described above, the best practice embodiments have been disclosed in the drawings and specifications. While specific terminology has been used herein, it is solely for the purpose of describing the present invention and is not intended to limit the scope of the invention as defined in the claims. Therefore, those skilled in the art will understand that various modifications and equivalent embodiments are possible. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.
