[0014] <Sealed container> The sealed container of the present invention comprises: A container body; The outer lid and The inner lid and Packing and A sealed container having The container body includes one or more content storage sections, The container body has a container thread, and the outer lid has a lid thread, which can be screwed together; The inner lid is attached to the inside of the outer lid so as to be rotatable coaxially with the outer lid, The packing is attached to the inside of the inner lid or is formed integrally with the inner lid on the inside of the inner lid, When the lid screw and the container screw are screwed together to fasten the outer lid to the container body, the packing forms a tight seal with the upper end of the opening of the content storage section of the container body. It is a sealed container.

[0015] In order to achieve a sufficient airtight seal in a container used for storing cosmetics, etc., it is considered easy and reliable to use a method in which, for example, in a roughly cylindrical container consisting of a screw-on lid and a container body having a contents storage section, a lid equipped with a gasket is screwed onto the container body, thereby crimping the gasket against the upper end of the contents storage section.

[0016] In addition, container designs that create a sense of luxury include, for example, making improvements to the container's material, shape, processing method, design, etc., as well as introducing asymmetrical elements into the container to create an exterior shape with a sense of tension, thereby creating a sense of luxury.

[0017] However, the prior art is not known to provide a container that can easily and reliably form a seal while also allowing for a design that can include, for example, asymmetrical elements to create a luxurious appearance.

[0018] In the present invention, the lid of the airtight container is divided into an inner lid for forming an airtight seal and an outer lid for screwing onto the container body, and the inner lid is attached inside the outer lid so as to be rotatable coaxially with the outer lid, thereby enabling easy and reliable airtight formation. In a preferred embodiment of the present invention, the upper end of the opening of the content storage section of the container body is positioned in a position that is not coaxial with the rotation direction of the container body, thereby introducing an asymmetrical element into the container and enabling a design that creates a sense of luxury.

[0019] That is, in a conventionally known sealed container, the packing is fixed to the lid, and when the lid is screwed onto the container body, the packing also rotates together with the rotation of the lid. Therefore, after the packing comes into contact with the upper end of the content storage section of the container body, the packing is pressed against the upper end of the content storage section while being rubbed against the upper end of the content storage section. In particular, when the central axis of the content storage section of the container body is not coaxial with the rotation direction (screw-in direction) of the container body, the packing is rubbed against the upper end of the content storage section over a wide area.

[0020] Therefore, the introduction of asymmetric elements into prior art sealed containers requires the selection of packing materials that are resistant to abrasion, which limits the range of material choices for forming the seal and raises concerns about premature deterioration of the packing.

[0021] In contrast, in the sealed container of the present invention, the inner lid having the packing is attached to the inside of the outer lid so as to be rotatable coaxially with the outer lid. With this configuration, when the lid is screwed onto the container body, the packing rotates together with the inner lid in accordance with the screwing rotation of the outer lid until the packing contacts the upper end of the content storage section of the container body.

[0022] However, after the packing comes into contact with the upper end of the content storage section of the container body, friction occurs between the packing and the upper end of the content storage section, and the packing and the inner lid stop rotating relative to the upper end of the content storage section (and therefore relative to the container body). Here, since the inner lid is attached to the inside of the outer lid so as to be rotatable coaxially with the outer lid, the outer lid can be subsequently screwed into the container body without any relative rotational movement between the packing and the upper end of the content storage section.

[0023] The sealed container of the present invention can easily and reliably form a hermetic seal by such an action mechanism. Furthermore, since the sealed container of the present invention can easily and reliably form a hermetic seal even when an asymmetric element is introduced, the degree of freedom in container design is increased, and a more luxurious container design is also possible.

[0024] The overall shape of the sealed container of the present invention is not particularly limited as long as the outer lid can be screwed into the container body. Therefore, the shape is typically axially symmetrical with a screw-in rotation axis, but is not limited thereto. The shape of the sealed container of the present invention may be, for example, a cylinder, a cylinder with the upper or lower part in the axial direction or both of them chamfered, a polygonal prism, a polygonal prism with the upper or lower part in the axial direction or both of them chamfered, a sphere, an oblong spheroid, or the like, or may be a shape combining two or more of these, or a shape with the bottom of these cut obliquely, or the like.

[0025] In the sealed container of the present invention, the container body is provided with one or more content storage sections.

[0026] When the container body has one content storage section, the upper end of the opening of this content storage section may or may not be coaxial with the rotation direction of the container body. In a sealed container in which the upper end of the opening of the content storage section is not coaxial with the rotation direction of the container body, an asymmetric element is introduced, enabling a more luxurious container design.

[0027] When the container body has a plurality of content storage sections, the upper ends of the openings of these content storage sections may or may not be coaxial with the rotation direction of the container body. In a sealed container in which the upper end of the opening of at least one content storage section is not coaxial with the rotation direction of the container body, an asymmetric element is introduced, enabling a more luxurious container design.

[0028] The container body may have one or more sub-storage sections in addition to the content storage section. The sub-storage sections may be recesses of any shape formed in the container body. The sub-storage sections may store, for example, beauty aids described below.

[0029] In the sealed container of the present invention, the packing is attached to the inside of the inner lid or is integrally formed with the inner lid on the inside of the inner lid. In the sealed container of the present invention, the packing and the upper end of the content storage section do not rotate relative to each other, and the seal can be formed without friction. Therefore, a material that is weak against friction can be used as the material of the packing, making it possible to form a seal more easily and reliably, and increasing the freedom of container design, making it possible to design a container with a more luxurious feel.

[0030] In a preferred embodiment, the sealed container of the present invention comprises: The container body has a container peripheral wall, and the container peripheral wall has a recess in an upper portion thereof, The inner lid has an inner lid peripheral wall, and the inner lid peripheral wall has a protrusion that can be accommodated in the recess of the container peripheral wall. It may also be something.

[0031] In this case, the convex portion of the inner lid peripheral wall may be slidable on the container peripheral wall of the container body when the container screw of the container body and the lid screw of the outer lid are screwed together. It is preferable that the positional relationship between the convex portion of the inner lid peripheral wall of the inner lid and the concave portion of the container peripheral wall of the container body is configured so that the lid screw of the outer lid and the container screw of the container body can or cannot be screwed together as described below.

[0032] (i) When the convex portion of the inner lid peripheral wall is not accommodated in the concave portion of the container peripheral wall of the container body, The inner lid rotates on the container body together with the outer lid. Due to contact between the convex portion of the inner lid peripheral wall and the upper end of the container peripheral wall of the container body, the inner lid and outer lid are restricted from approaching the container body, thereby preventing the lid screws of the outer lid from screwing into the container screws of the container body.

[0033] (ii) However, when the convex portion of the inner lid peripheral wall is accommodated in the concave portion of the container peripheral wall of the container body, The convex portion of the inner lid peripheral wall is accommodated in the concave portion of the container body, thereby restricting the rotation of the inner lid on the container body, and The inner and outer lids have unrestricted access to the container body, allowing the lid threads on the outer lid to threadably engage with the container threads on the container body.

[0034] With this configuration, when the convex portion of the inner lid peripheral wall is housed in the concave portion of the container body, the relative movement between the inner lid and the container body is restricted, so it is sufficient to place the packing in the inner lid at a position and with a necessary area required for sealing with the upper end of the content storage portion of the container body. Therefore, with this configuration, asymmetric elements can be introduced not only into the container body but also into the lid, making it possible to create a more sophisticated and luxurious design.

[0035] The recess in the peripheral wall of the container body may be a rectangular recess, or may be a recess having a shape with an inclined portion in which the height of the peripheral wall of the container gradually decreases and then gradually increases.

[0036] The number of each of the convex portion on the inner lid peripheral wall of the inner lid and the concave portion on the container peripheral wall of the container body may be one or more. When the inner lid peripheral wall has a plurality of convex portions, it is preferable that the container peripheral wall of the container body has the same number of concave portions as the convex portions or more in appropriate positions so as to accommodate all of the convex portions, restrict the rotation of the inner lid on the container body, and allow the inner lid and the outer lid to approach the container body.

[0037] The container body may be made of a single component, or may be made up of a combination of multiple components.

[0038] The container body composed of a plurality of parts is, for example, It may have an inner container portion and an outer container portion, It may have a content exchange container portion, an inner container portion, and an outer container portion, The container may further include other container parts.

[0039] Examples of container parts other than the container part for replacing contents, the inner container part, and the outer container part include, but are not limited to, a container part for covering which is attached further outside the outer container part to impart a design effect.

[0040] When the container body has an inner container portion and an outer container portion, The inner container portion has a container peripheral wall and a content storage portion, and is housed in the outer container portion; The outer container portion may have container threads that mate with the lid threads.

[0041] In this configuration, the inner container portion having the container peripheral wall has a recess.

[0042] In this configuration, when the inner container part is housed in the outer container part, a gap may be formed between the outside of the inner container part and the inside of the outer container part, so that a spatula can be housed in the gap between the outside of the inner container part and the inside of the outer container part.

[0043] In the case where the container body has a content exchange container portion, an inner container portion, and an outer container portion, The content exchange container portion has a content storage portion and is stored in the inner container portion; The inner container portion has a container peripheral wall and is housed in the outer container portion; The outer container portion may have container threads that mate with the lid threads.

[0044] In this configuration as well, the inner container portion having the container peripheral wall has a recess.

[0045] It is preferable that the content replacement container part is stored so as to be removable from the inner container part. If the content replacement container part is removable from the inner container part, it becomes possible to reuse the sealed container by replacing the content replacement container part after the content has been used up with a new content replacement container part filled with the content.

[0046] In this configuration, when the content replacement container part is stored in the inner container part, a gap may be formed between the outside of the content replacement container part and the inside of the inner container part. With this configuration, a beauty aid can be stored in the gap between the outside of the content replacement container part and the inside of the inner container part.

[0047] Examples of beauty aids stored in at least one of the secondary storage section of the container body and the space between the outside of the container section for replacing the contents and the inside of the inner container section include spatulas, brushes, droppers, massage tools, combs, files, puffs, sponges, scissors, eye shadow tips, nail clippers, etc.

[0048] The outer cover may be made of a single piece, or may be made of a combination of multiple pieces.

[0049] The multi-part outer lid may include a screw-on lid and a cover lid.

[0050] In this case, the screw-on lid has lid threads that mate with the container threads.

[0051] The cover lid can cover the outside of the screw-on lid and can add a design effect to the airtight container.

[0052] 《Container with contents》 In another aspect of the present invention, there is provided a content-containing sealed container, in which a content is stored in a content storage section of the above-mentioned sealed container.

[0053] The contents stored in the content-containing sealed container of the present invention may be, for example, cosmetics, medicines, food, etc. EXAMPLES

[0054] Hereinafter, specific embodiments of the sealed container of the present invention will be described in detail by way of examples with reference to the drawings. However, the present invention is not limited to the following examples. The scope of the present invention is defined by the appended claims.

[0055] Example 1 A schematic cross-sectional view of the sealed container of Example 1 is shown in FIG.

[0056] The sealed container (100) of the first embodiment is a substantially cylindrical container, and includes a container body (110), an outer lid (120), an inner lid (130), and a packing (140).

[0057] The container body (110) includes a content storage section (115a) and a container peripheral wall (112) surrounding the periphery of the content storage section (115a).

[0058] The content storage section (115a) has a substantially circular opening when viewed from above, with an upper end (115b) at the periphery of the opening that protrudes slightly upward from the upper flat surface (111a) of the container body (110).

[0059] In the sealed container (100), the upper end (115b) of the opening of the content storage section (115a) is not coaxial with the rotational direction of the container body (110). Looking at the sealed container (100) in Fig. 1, the rotation axis (A11) of the container body (110) and the central axis (A12) of the content storage section (115a) do not coincide with each other, and an asymmetric element is introduced into the sealed container (100).

[0060] The container body (110) has a container thread (114a), and the outer lid (120) has a lid thread (121a), which can be screwed together. The inner lid (130) is attached to the inside of the outer lid (120) so as to be rotatable coaxially with the outer lid (120). In other words, the inner lid (130) can rotate relatively to the outer lid (120) around the same axis as the rotation axis (A11) of the container body (110) while remaining attached to the outer lid (120).

[0061] The inner lid (130) has an inner lid inner bottom surface (131) and an inner lid peripheral wall (132), and a packing (140) is attached so as to cover almost the entire inner lid inner bottom surface (131).

[0062] In the sealed container (100) of Example 1, when the lid screw (121a) and the container screw (114a) are screwed together to tighten the outer lid (120) onto the container body (110), the packing (140) is configured to form a tight seal with the opening upper end (111b) of the content storage section (115a) of the container body (110).

[0063] At this time, when the outer lid (120) is gradually screwed onto the container body (110) from the open state of the sealed container (100), the inner lid (130) rotates following the rotation of the outer lid (120) while the packing (140) attached to the inside bottom surface (131) of the inner lid (130) is not in contact with the upper end (115b) of the opening of the content storage section (115a). At this time, the inner lid (130) may be stationary relative to the outer lid (120) and may rotate relative to the container body (110).

[0064] However, when the outer lid (120) is screwed further into the container body (110) and the lid threads (121a) and the container threads (114a) are engaged to a certain extent, the packing (140) comes into contact with the upper end (115b) of the opening of the content-storage section (115a), generating friction between them. Then, the inner lid (130) starts to rotate coaxially with the outer lid (120) relative to the outer lid (120).

[0065] At this time, the inner lid (130) is stationary relative to the container body (110). Therefore, by continuing to tighten in this state, the upper end (115b) of the opening and the packing (140) can be pressed together without the upper end (115b) of the opening rubbing against the surface of the packing (140), and the packing (140) is elastically compressed in a direction perpendicular to its surface, forming a tight seal between the packing (140) and the upper end (115b) of the opening.

[0066] Example 2 Schematic cross-sectional views of the sealed container of Example 2 are shown in FIG. 2 and FIG.

[0067] The sealed container (200) of the second embodiment is a substantially cylindrical container, and includes a container body (210), an outer lid (220), an inner lid (230), and a packing (240).

[0068] FIG. 2 shows the state when the outer lid (220) starts to be screwed onto the container body (210), and FIG. 3 shows the state when the screws are screwed together to seal the container.

[0069] The sealed container (200) of the second embodiment is a substantially cylindrical container, and includes a container body (210), an outer lid (220), an inner lid (230), and a packing (240).

[0070] In the sealed container (200) of Example 2, The container body (210) is provided with a content storage section (215a) having a substantially circular opening, and has a container peripheral wall (212) surrounding the periphery of the content storage section (215a); The peripheral edge of the opening of the content storage section (215a) has an upper opening edge (215b); The upper end (215b) of the opening of the content storage section (215a) is not concentric with the rotational direction of the container body (210) but has an asymmetrical element introduced therein; The container body (210) has a container thread (214a) and the outer lid (220) has a lid thread (221a), which can be screwed together; and The inner lid (230) is attached inside the outer lid (220) so as to be rotatable coaxially with the outer lid (220). are the same as those of the sealed container (100) of the first embodiment.

[0071] However, in the sealed container (200), a partial region of the upper part of the container peripheral wall (212) of the container body (210) has a recess (213) recessed from the upper flat surface (211a) of the container body (210).

[0072] The inner lid (230) of the sealed container (200) has an inner bottom surface (231) of the inner lid and an inner lid peripheral wall (232), and the inner lid peripheral wall (232) has at least one protrusion (233) protruding inward. The protrusion (233) can be received in the recess (213) of the container body (210).

[0073] A packing (240) is attached to a portion of the inside bottom surface (231) of the inner lid. The packing (240) is located at a position and of a size that allows a tight seal to be formed between the packing (240) and the upper end (215b) of the opening of the content-accommodating section (215a) when the sealed container (200) is in a sealed state.

[0074] Therefore, in the sealed container (200) of FIG. 2 as well, when the cover screw (221a) and the container screw (214a) are screwed together and the outer cover (220) is fastened to the container body (210), the container is sealed.

[0075] FIG. 2 is a schematic cross-sectional view showing the state of the sealed container (200) when the outer lid (220) starts to be screwed onto the container body (210).

[0076] When the outer lid (220) is gradually screwed onto the container body (210) from an open state of the sealed container (200), the packing (240) attached to the inside bottom surface (231) of the inner lid (230) is not necessarily in a position where it can form a tight seal with the upper end (215b) of the opening of the content storage section (215a). Figure 2 shows a state where the packing (240) and the opening of the content storage section (215a) are not aligned. If the packing (240) were to move downward from the position shown in Figure 2, it would not be possible to form a tight seal between the packing (240) and the upper end (215b) of the opening.

[0077] However, when the positions of the gasket (240) and the opening of the content storage section (215a) are not aligned, the convex portion (233) of the inner lid (230) comes into contact with the upper flat surface (211a) of the container body (210), and the inner lid (230) and the outer lid (220) to which the inner lid (230) is attached are restricted in their descent and cannot approach the container body (210). As a result, the lid screw (221a) of the outer lid (220) cannot screw into the container screw (214a) of the container body (210).

[0078] At this time, the packing (240) is not in contact with the upper end (215b) of the opening of the content storage section (215a), and no frictional force is generated between them, so the inner lid (230) can rotate following the rotation of the outer lid (220). Therefore, if the outer lid (220) continues to be screwed in while the lid screw (221a) and the container screw (214a) are not screwed together, the inner lid (230) will rotate on the container body (210) together with the outer lid (220), and the position of the packing (240) attached to the inner lid (230) may become aligned with the position of the opening of the content storage section (215a) of the container body (210).

[0079] In the sealed container (200) of Example 2, when the position of the packing (240) and the position of the opening of the content storage section (215a) are aligned, the position of the convex portion (233) of the inner lid peripheral wall (232) coincides with the position of the concave portion (213) of the container peripheral wall (212), so that the convex portion (233) of the inner lid peripheral wall (232) can be accommodated in the concave portion (213) of the container peripheral wall (212). At this time, a pressing force is applied by the user between the container body (210) and the outer lid (220) and the inner lid (230) in directions that bring them closer to each other. Therefore, the convex portion (233) is stored in the concave portion (213), and as a result, the outer lid (220) and the inner lid (230) approach the container body (210) and the lid screw (221a) of the outer lid (220) begins to screw into the container screw (214a) of the container body (210).

[0080] Furthermore, when the convex portion (233) of the inner lid peripheral wall (232) is housed in the concave portion (213) of the container peripheral wall (212), even if the outer lid (220) is rotated to advance the engagement between the lid screw (221a) and the container screw (214a), the rotation of the inner lid (230) on the container body (210) is restricted. Therefore, during the rotation of the outer lid (220) in this case, the aligned positional relationship between the packing (240) and the opening of the content storage section (215a) is generally maintained.

[0081] The positional relationship being "generally maintained" means that in order to make storage by the user's pressing force easy and reliable, there may be some play between the convex portion (233) and the concave portion (213) when stored, and therefore the positional relationship between the two is not limited to being strictly fixed.

[0082] When the outer lid (220) continues to rotate and the lid screw (221a) and the container screw (214a) are screwed together to a certain extent, the packing (240) comes into contact with the upper end (215b) of the opening of the content storage section (215a), generating friction between them, and the inner lid (230) stops relative to the container body (210). By continuing to tighten in this state, the upper end (215b) of the opening is pressed against the packing (240) without the upper end (215b) rubbing against the surface of the packing (240), forming a tight seal (see FIG. 3).

[0083] In the sealed container (200) of the second embodiment, the content storage section (215a) is not limited to one, and may be two or more. Also, a sub-storage section may be formed in the container body (210), and appropriate beauty aids may be stored in this sub-storage section.

[0084] Example 3 Schematic diagrams of the sealed container of Example 3 are shown in FIG. 4 to FIG.

[0085] The sealed container (300) of the third embodiment is a substantially cylindrical container, and includes a container body (310), an outer lid (320), an inner lid (330), and a packing (340).

[0086] In the sealed container (300) of the third embodiment, the container body (310) has an inner container part (311) and an outer container part (314), and the inner container part (311) is housed in the outer container part (314).

[0087] The inner container portion (311) of the container body (310) has a content storage section (315a) having a substantially circular opening, and a container peripheral wall (312) surrounding the periphery of the content storage section (315a). The peripheral edge of the opening of the content storage section (315a) has an opening upper edge (315b).

[0088] In the sealed container (300) of Example 3, a partial region of the upper part of the container peripheral wall (312) surrounding the periphery of the content storage section (315a) has a recess (313) recessed from the upper flat surface (311a) of the container body (310). This recess (313) has an inclined portion where the height from the upper flat surface (311a) of the container body (310) gradually decreases and then gradually increases.

[0089] On the other hand, the outer container portion (314) of the container body (310) has container threads (314a) which mesh with lid threads (321a) of the outer lid (320).

[0090] The remaining configuration of the sealed container (300) of the third embodiment is similar to that of the sealed container (200) of the second embodiment.

[0091] 4 to 6 show examples of the shape of the inner lid (330) of the sealed container (300). Fig. 4 is a top view of the inner lid (330), Fig. 5 is a bottom view, and Fig. 6 is a cross-sectional view taken along line AA.

[0092] The inner lid (330) of the sealed container (300) has an inner bottom surface (331) of the inner lid and an inner lid peripheral wall (332), and the inner lid peripheral wall (332) has at least one protrusion (333) protruding inward. This protrusion (333) can be received in a recess (313) of the outer container part (314) of the container body (310).

[0093] A packing (340) is attached to a portion of the inside bottom surface (331) of the inner lid. The packing (340) is located at a position and of a size that allows a tight seal between the packing (340) and the upper end (315b) of the opening of the content storage section (315a) of the inner container part (311) of the container body (310) when the sealed container (300) is in a sealed state.

[0094] 7 to 9 show an example of a state in which the inner lid (330) of the sealed container (300) is attached in the outer lid (320). Fig. 7 is a top view of the outer lid (320) and the inner lid (330), Fig. 8 is a bottom view, and Fig. 9 is a cross-sectional view taken along line AA. The inner lid (330) is attached in the outer lid (320) so as to be rotatable coaxially with the outer lid (320).

[0095] 10 to 13 show examples of the shape of the inner container part (311) of the container body (310) of the sealed container (300). Fig. 10 is a top view of the inner container part (311), Fig. 11 is a bottom view, Fig. 12 is a cross-sectional view taken along line AA, and Fig. 13 is a perspective view.

[0096] The inner container portion (311) in FIGS. 10 to 13 includes a content-accommodating section (315a) and a container peripheral wall (312) surrounding the content-accommodating section (315a).

[0097] The content storage section (315a) has a substantially circular opening when viewed from above, with an upper edge (315b) of the opening protruding slightly upward from the upper flat surface (311a) of the inner container portion (311) at its peripheral edge.

[0098] The inner container portion (311) of the container body (310) of the sealed container (300) has a recess (313) that is recessed in a partial region of the upper part of the container peripheral wall (312). The recess (313) has an inclined portion whose height from the upper flat surface (331a) of the container body (310) gradually decreases and then gradually increases.

[0099] Figures 14 to 17 show an example of a state in which the inner container part (311) of the container body (310) of the sealed container (300) is housed in the outer container part (314). Figure 14 is a top view of the inner container part (311) and the outer container part (314), Figure 15 is a bottom view, Figure 16 is a cross-sectional view taken along line AA, and Figure 17 is a perspective view. With reference to Figures 16 and 17, it can be seen that the container body (310) is composed of the inner container part (311) and the outer container part (314).

[0100] The upper end (315b) of the opening of the content storage section (315a) of the inner container portion (311) is not coaxial with the rotational direction of the container body (310). That is, as shown in the cross-sectional view taken along line AA in Figure 16, the rotational axis (A31) of the container body (310) and the central axis (A32) of the content storage section (315a) do not coincide with each other, and an asymmetric element is introduced into the sealed container (300).

[0101] FIG. 16 also shows that a gap (316) is formed between the outside of the inner container portion (311) and the inside of the outer container portion (314), on the side farther from the rotation axis (A32) of the content storage section (315a) with respect to the rotation axis (A31) of the container body (310).

[0102] 18 and 19 are schematic cross-sectional views showing the state of the sealed container (300) when starting to screw the lid onto the container body (310). In Fig. 18, only the inner container part (311), the packing (340), and the inner lid (330) are shown, while in Fig. 19, in addition to these, the outer container part (314) and the outer lid (320) are also shown.

[0103] When the outer lid (320) and the inner lid (330) are gradually screwed onto the container body (310) from the open state of the sealed container (300), the gasket (340) attached to the inner bottom surface (331) of the inner lid (330) is not necessarily in a position where it can form a tight seal with the upper end (315b) of the opening of the content storage section (315a). However, when the positions of the gasket (340) and the opening of the content storage section (315a) are not aligned, the convex portion (333) of the inner lid (330) comes into contact with the upper flat surface (311a) of the inner container portion (311), and the inner lid (330) and the outer lid (320) to which the inner lid (330) is attached are restricted in their descent and cannot approach the container body (310). Therefore, the lid screw (321a) of the outer lid (320) cannot screw into the container screw (314a) of the outer container portion (314).

[0104] At this time, the packing (340) is not in contact with the upper end (315b) of the opening of the content-storing section (315a) and no frictional force is generated between them, so that the inner lid (330) can rotate following the rotation of the outer lid (320). Therefore, if screwing is continued in the state of Figures 18 and 19, the inner lid (330) rotates together with the outer lid (320) on the container body (310), and the position of the packing (340) attached to the inner lid (330) may become aligned with the position of the opening of the content-storing section (315a) of the inner-container portion (311).

[0105] 20 and 21 are schematic cross-sectional views showing the sealed container (300) when the position of the packing (340) and the position of the opening of the content storage section (315a) are aligned. In Fig. 18, only the inner container part (311), the packing (340), and the inner lid (330) are shown, while in Fig. 19, in addition to these, the outer container part (314) and the outer lid (320) are also shown.

[0106] In this sealed container (300), when the position of the packing (340) and the position of the opening of the content storage section (315a) are aligned, the position of the convex portion (333) of the inner lid (330) and the position of the concave portion (313) of the container peripheral wall (312) coincide with each other, so that the convex portion (333) of the inner lid (330) can be stored in the concave portion (313) of the inner container section (311). At this time, a pressing force is applied by the user between the container body (310) and the outer lid (320) and the inner lid (330) in directions that bring them closer to each other. Therefore, the convex portion (333) is stored in the concave portion (313), and as a result, the outer lid (320) and the inner lid (330) approach the container body (310), and the lid thread (321a) of the outer lid (320) begins to screw into the container thread (314a) of the outer container part (314).

[0107] Furthermore, when the convex portion (333) of the inner lid (330) is housed in the concave portion (313) of the inner-container portion (311), even if the outer lid (320) is rotated to advance the engagement between the lid screw (321a) and the container screw (314a), the rotation of the inner lid (330) on the container body (310) is restricted. Therefore, during the rotation of the outer lid (320) in this case, the aligned positional relationship between the packing (340) and the opening of the content storage portion (315a) is generally maintained.

[0108] When the outer lid (320) continues to rotate and the lid screw (321a) and the container screw (314a) are screwed together to a certain extent, the packing (340) comes into contact with the upper end (315b) of the opening of the content storage section (315a), generating friction between them, and the inner lid (330) stops relative to the container body (310). By continuing to tighten in this state, the upper end (315b) of the opening is pressed against the packing (340) without rubbing against the surface of the packing (340), forming a tight seal (see Figures 20 and 21).

[0109] As described above, a space may be formed between the outside of the inner container part and the inside of the outer container part, and a spatula may be stored in this space. Figure 22 shows a state in which a spatula (350) is stored in the space (316) formed between the outside of the inner container part (311) and the inside of the outer container part (314) of the sealed container (300).

[0110] Example 4 23 to 48 are schematic diagrams of the sealed container of Example 4.

[0111] The sealed container (400) of the fourth embodiment is a substantially cylindrical container with chamfered top and bottom in the axial direction of the cylinder. The sealed container (400) includes a container body (410), an outer lid (420), an inner lid (430), and a packing (440).

[0112] In the sealed container (400) of the fourth embodiment, the container body (410) has a container portion (415) for replacing the contents, an inner container portion (411), and an outer container portion (414). The container portion (415) for replacing the contents is housed in the inner container portion (411), and the inner container portion (411) is housed in the outer container portion (414).

[0113] The content replacement container part (415) is removably housed in the inner container part (411). By making the content replacement container part (415) removable from the inner container part (411), the content replacement container part (415) after the contents have been used up can be replaced with a new content replacement container part (415) filled with the contents, thereby making it possible to reuse the sealed container (400).

[0114] The content replacement container portion (415) of the container body (410) includes a content storage portion (415a) having a substantially circular opening, and the peripheral edge of the opening of the content replacement container portion (415) has an opening upper end (415b).

[0115] The inner container part (411) has a container peripheral wall (412) surrounding the periphery of the inner container part (411), and a partial region of the upper part of the container peripheral wall (412) has a recess (413) recessed from the upper flat surface (411a) of the inner container part (411). The recess (413) has an inclined portion where the height from the upper flat surface (411a) of the inner container part (411) gradually decreases and then gradually increases.

[0116] The outer container portion (414) of the container body (410) has container threads (414a) which mesh with lid threads (421a) of the screw-on lid (421).

[0117] The outer lid (420) of the sealed container (400) of the fourth embodiment has a screw-on lid (421) and a cover lid (422). The screw-on lid (421) has lid threads (421a) that mesh with the container threads (414a).

[0118] The cover lid (422) can cover the outside of the screw-on lid (421) and can add a design effect to the airtight container (400).

[0119] The remaining configuration of the sealed container (400) of the fourth embodiment is similar to that of the sealed container (300) of the third embodiment.

[0120] 23 to 25 show examples of the shape of the inner lid (430) of the sealed container (400). Fig. 23 is a top view of the inner lid (430), Fig. 24 is a bottom view, and Fig. 25 is a cross-sectional view taken along line AA.

[0121] The inner lid (430) of the sealed container (400) has an inner bottom surface (431) of the inner lid and an inner lid peripheral wall (432), and the inner lid peripheral wall (432) has at least one protrusion (433) protruding inward. The protrusion (433) can be received in a recess (413) of the inner container portion (411) of the container body (410).

[0122] A packing (440) is attached to a portion of the inside bottom surface (431) of the inner lid. This packing (440) is located at a position and sized to form a tight seal between the packing (440) and the upper end (415b) of the opening of the contents storage section (415a) of the contents exchange container portion (415) of the container body (410) when the sealed container (400) is in a sealed state.

[0123] 26 to 28 show an example of a state in which the inner lid (430) of the sealed container (400) is attached to the screw-in lid (421) of the outer lid (420). FIG. 26 is a top view of the screw-in lid (421) and the inner lid (430), FIG. 27 is a bottom view, and FIG. 28 is a cross-sectional view taken along line AA. The inner lid (430) is attached to the screw-in lid (421) so as to be rotatable coaxially with the screw-in lid (421). Therefore, the inner lid (430) can also rotate coaxially with respect to the outer lid (420).

[0124] 29 to 31 show the inner lid (430) and the screw-in lid (421) together with the cover lid (422). Fig. 29 is a top view of the screw-in lid (421), the cover lid (422), and the inner lid (430), Fig. 30 is a bottom view, and Fig. 31 is a cross-sectional view taken along line AA. As can be seen in these figures, the outer lid (420) of the sealed container (400) includes the screw-in lid (421) and the cover lid (422).

[0125] 32 to 35 show examples of the shape of the inner container part (411) of the container body (410) of the sealed container (400). Fig. 32 is a top view of the inner container part (411), Fig. 33 is a bottom view, Fig. 34 is a cross-sectional view taken along line AA, and Fig. 35 is a perspective view.

[0126] 32 to 35 has a sunken recess (413) in a partial region of the upper part of the container peripheral wall (412). The recess (413) has an inclined portion whose height from the upper flat surface (411a) of the inner container part (411) gradually decreases and then gradually increases.

[0127] 36 to 39 show a state in which the content replacement container part (415) is housed in the inner container part (411). Fig. 36 is a top view of the inner container part (411) and the content replacement container part (415), Fig. 37 is a bottom view, Fig. 38 is a cross-sectional view taken along line AA, and Fig. 39 is a perspective view.

[0128] 36 to 39, the contents replacement container portion (415) includes a contents storage section (415a). The contents storage section (415a) may have a substantially circular opening when viewed from above, and the peripheral edge of the opening forms the opening upper end (415b). The opening upper end (415b) may have a shape that protrudes slightly upward from the rest of the peripheral edge of the opening, or the entire peripheral edge of the opening may be the opening upper end (415b).

[0129] Figure 38 shows that a gap (416) is formed between the outside of the content replacement container part (415) and the inside of the inner container part (411). As shown in Figure 42, which will be described later, this gap (416) is formed on the side of the rotation axis (A41) of the container body (410) that is farther from the central axis (A42) of the content storage part (415a).

[0130] 40 to 43 show an example of a state in which the inner container part (411) and the content replacement container part (415) of the container body (410) of the sealed container (400) are housed in the outer container part (414). Fig. 40 is a top view of the inner container part (411), the content replacement container part (415), and the outer container part (414), Fig. 41 is a bottom view, Fig. 42 is a cross-sectional view taken along line AA, and Fig. 43 is a perspective view. With reference to Figs. 42 and 43, it can be seen that the container body (410) is composed of the inner container part (411), the content replacement container part (415), and the outer container part (414).

[0131] The upper end (415b) of the opening of the content storage section (415a) of the content replacement container portion (415) is not coaxial with the rotational direction of the container body (410). That is, as shown in the cross-sectional view of line AA in Figure 42, the rotational axis (A41) of the container body (410) and the central axis (A42) of the content storage section (415a) do not coincide with each other, and an asymmetric element is introduced into the sealed container (400).

[0132] Figures 44 and 45 are schematic cross-sectional views showing the state of the sealed container (400) when starting to screw the lid onto the container body (410). Figure 44 shows only the inner container part (411), the content replacement container part (415), the packing (440), and the inner lid (430), while Figure 45 shows the outer container part (414) and the screw-on lid (421) in addition to these. The cover lid is not shown in Figures 44 and 45.

[0133] When the screw-on lid (421) and the inner lid (430) are gradually screwed into the container body (410) from the open state of the sealed container (400), the gasket (440) attached to the inner bottom surface (431) of the inner lid (430) is not necessarily in a position where it can form a tight seal with the upper end (415b) of the opening of the content storage section (415a). However, when the positions of the gasket (440) and the opening of the content storage section (415a) are not aligned, the convex portion (433) of the inner lid (430) comes into contact with the upper flat surface (411a) of the inner container portion (411), and the inner lid (430) and the screw-on lid (421) to which the inner lid (430) is attached are restricted in their descent and cannot approach the container body (410). Therefore, the lid screw (421a) of the screw-on lid (421) cannot screw into the container screw (414a) of the outer container portion (414).

[0134] At this time, the packing (440) is not in contact with the upper end (415b) of the opening of the content storage section (415a) and no frictional force is generated between them, so that the inner lid (430) can rotate following the rotation of the screw-in lid (421). Therefore, if screwing is continued in the state of Figures 44 and 45, the inner lid (430) rotates together with the screw-in lid (421) on the container body (410), and the position of the packing (440) attached to the inner lid (430) may become aligned with the position of the opening of the content storage section (415a) of the content exchange container part (415).

[0135] Figures 46 and 47 are schematic cross-sectional views showing the sealed container (400) when the position of the packing (440) and the position of the opening of the content storage section (415a) are aligned. Figure 46 shows only the inner container part (411), the content replacement container part (415), the packing (440), and the inner lid (430), while Figure 47 shows the outer container part (414) and the screw-on lid (421) in addition to these. The cover lid is not shown in Figures 46 and 47.

[0136] In this sealed container (400), when the position of the packing (440) and the position of the opening of the content storage section (415a) are aligned, the position of the convex portion (433) of the inner lid (430) and the position of the concave portion (413) of the inner container section (411) coincide with each other, so that the convex portion (433) of the inner lid (430) can be accommodated in the concave portion (413) of the inner container section (411). At this time, a pressing force is applied by the user between the container body (410) and the screw-on lid (421) and the inner lid (430) in directions that bring them closer to each other. Therefore, the convex portion (433) is stored in the concave portion (413), and as a result, the screw-on lid (421) and the inner lid (430) approach the container body (410), and the lid threads (421a) of the screw-on lid (421) begin to screw into the container threads (414a) of the outer container part (414).

[0137] Furthermore, when the convex portion (433) of the inner lid (430) is housed in the concave portion (413) of the inner-container portion (411), even if the screw-on lid (421) is rotated to advance the engagement between the lid screw (421a) and the container screw (414a), the rotation of the inner lid (430) on the container body (410) is restricted. Therefore, during the rotation of the screw-on lid (421) in this case, the aligned positional relationship between the packing (440) and the opening of the content-storing portion (415a) is generally maintained.

[0138] When the screw-in lid (421) continues to rotate and the lid screw (421a) is screwed into the container screw (414a) to a certain extent, the packing (440) comes into contact with the upper end (415b) of the opening of the content storage section (415a), generating friction between them, and the inner lid (430) stops relative to the container body (410). By continuing to tighten in this state, the upper end (415b) of the opening is pressed against the packing (440) without the upper end (415b) rubbing against the surface of the packing (440), forming a tight seal (see Figures 46 and 47).

[0139] In the sealed container (400) of the fourth embodiment, a space may be formed between the outside of the container part for replacing the contents and the inside of the inner container part, and a spatula may be stored in this space. Fig. 48 shows a state in which a spatula (450) is stored in the space (416) formed between the outside of the container part for replacing the contents (415) and the inside of the inner container part (411) of the sealed container (400). Fig. 48 also shows a cover lid (422). [Explanation of symbols]
