Description

The present invention relates to a sealed container.

Containers used for cosmetics, especially luxury cosmetics, must have the basic functionality of a container, as well as a design that creates a sense of luxury in order to appeal to consumers and ensure satisfaction for purchasers.

The basic function of a container is, for example, to be a sealed container with sufficient sealing properties to prevent leakage, deterioration, etc. of the contents. In this regard, Patent Document 1 proposes a container with an inner lid that includes a container body in which the contents are stored, and an inner lid that is detachably attached to the opening of the container body.

In addition, when the contents are a cosmetic product with a relatively high viscosity, a dispenser such as a spatula suitable for dispensing the appropriate amount of the cosmetic product may be attached to the container. Depending on the area to which the cosmetic product is to be applied and the method of use, the container also often includes beauty aids such as brushes, droppers, massage tools, combs, files, puffs, sponges, etc. These beauty aids, including spatulas, are held in the container by, for example, placing them on the inner lid of the container (Patent Document 2) or inserting them into recesses in the base of the container.

In terms of container design, the material, shape, processing method, design, etc. of the container are carefully considered according to the brand concept, product price range, target demographic attributes, product usage scenarios, etc.

<Sealed container>
The sealed container of the present invention comprises:
A container body;
The outer lid and
The inner lid and
A sealed container having a packing,
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.

In order to form a sufficient airtight seal in a container used to store 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 content storage section, the lid equipped with a packing is screwed onto the container body, thereby crimping the packing onto the upper end of the content storage section.

In addition, container designs that create a sense of luxury can be achieved by, for example, taking into consideration the material, shape, processing method, and design of the container, 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.

However, in the prior art, no container was known that could easily and reliably form a tight seal and that could be designed, for example, to include asymmetrical elements and create a luxurious feel.

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 to the inside of the outer lid so that it can rotate coaxially with the outer lid, making it possible to easily and reliably form an airtight seal. In a preferred embodiment of the present invention, the upper end of the opening of the contents storage section of the container body is positioned in a position that is not coaxial with the direction of rotation of the container body, introducing an asymmetrical element into the container and making it possible to create a design that creates a sense of luxury.

In other words, in conventionally known airtight containers, the gasket is fixed to the lid, and when the lid is screwed onto the container body, the gasket rotates along with the rotation of the lid. Therefore, after the gasket comes into contact with the upper end of the contents storage section of the container body, the gasket is pressed against the upper end of the contents storage section while being rubbed against it. In particular, if the central axis of the contents storage section of the container body is not coaxial with the rotation direction (screw-in direction) of the container body, the gasket will be rubbed against the upper end of the contents storage section over a wide area.

Therefore, introducing an asymmetric element into a conventional sealed container requires the selection of a packing material that is resistant to friction, narrowing the scope of material choices for forming a seal and raising concerns about premature deterioration of the packing.

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 that it can rotate 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 response to the screwing rotation of the outer lid until the packing comes into contact with the upper end of the contents storage section of the container body.

However, after the packing comes into contact with the upper end of the contents storage section of the container body, friction occurs between the packing and the upper end of the contents storage section, causing the packing and inner lid to stop rotating relative to the upper end of the contents storage section (and therefore relative to the container body). Here, because the inner lid is attached to the inside of the outer lid so that it can rotate coaxially with the outer lid, the outer lid can continue to be screwed into the container body without there being any relative rotational movement between the packing and the upper end of the contents storage section.

The airtight container of the present invention can easily and reliably form a seal due to this mechanism of action. Furthermore, because the airtight container of the present invention can easily and reliably form a seal even when an asymmetric element is introduced, the freedom of container design is increased, making it possible to design containers with a more luxurious feel.

The overall shape of the sealed container of the present invention is not particularly limited as long as it allows the outer lid to be screwed onto the container body. Therefore, it is typically an axially symmetrical shape having an axis of rotation for screwing, but is not limited to this. The shape of the sealed container of the present invention may be, for example, a cylinder, a cylinder with the upper or lower axial direction or both of them chamfered, a polygonal prism, a polygonal prism with the upper or lower axial direction or both of them chamfered, a sphere, an oblong spheroid, etc., and may also be a shape combining two or more of these, a shape with the bottom cut diagonally, etc.

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

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 rotational 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 rotational direction of the container body, an asymmetrical element is introduced, allowing for a more luxurious container design.

When the container body has multiple content storage sections, the upper ends of the openings of these content storage sections may or may not be coaxial with the rotational 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 rotational direction of the container body, an asymmetric element is introduced, allowing for a more luxurious container design.

The container body may have one or more sub-storage sections in addition to the content storage section. The sub-storage section may be a recess of any shape formed in the container body. This sub-storage section may store, for example, a beauty aid, which will be described later.

In the sealed container of the present invention, 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. 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 a seal can be formed without friction. Therefore, a material that is weak against friction can be used as the material for the packing, making it possible to form an easier and more reliable seal, and also increasing the freedom of container design, allowing for a more luxurious container design.

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 may have an inner lid peripheral wall, and the inner lid peripheral wall may have a protrusion that can be received in a recess in the container peripheral wall.

In this case, when the container screw of the container body and the lid screw of the outer lid are screwed together, the convex portion of the inner lid peripheral wall may be able to slide on the container peripheral wall of the container body. 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 follows.

(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.

(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,
Because the convex portion of the peripheral wall of the inner lid is accommodated in the concave portion of the container body, rotation of the inner lid on the container body is restricted, and the approach of the inner lid and outer lid to the container body is not restricted, thereby allowing the lid screw of the outer lid to screw into the container screw of the container body.

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 in the position required to form a tight seal with the upper end of the content storage section of the container body, and with the required area. 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.

The recess in the peripheral wall of the container body may be a rectangular recess, or may be a recess with a shape that includes a sloping portion in which the height of the peripheral wall of the container gradually decreases and then gradually increases.

The number of convex portions on the inner lid peripheral wall of the inner lid and the number of concave portions on the container peripheral wall of the container body may be one each or multiple each. If the inner lid peripheral wall has multiple 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 that all of them can be accommodated, rotation of the inner lid on the container body is restricted, and the inner lid and outer lid can be brought close to the container body.

The container body may consist of a single component, or may be made up of multiple components assembled together.

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.

Container parts other than the container part for replacing contents, the inner container part, and the outer container part include, for example, a container part for a cover that is attached to the outside of the outer container part to provide a design effect, but are not limited to this.

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.

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

In this configuration, when the inner container part is stored 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. With this configuration, a spatula can be stored in the gap between the outside of the inner container part and the inside of the outer container part.

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.

Even in this configuration, the inner container portion that has the container peripheral wall has a recess.

It is preferable that the container portion for replacing the contents is stored so that it can be removed from the inner container portion. If the container portion for replacing the contents is removable from the inner container portion, it becomes possible to reuse the sealed container by replacing the container portion for replacing the contents after the contents have been used up with a new container portion for replacing the contents filled with the contents.

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.

Examples of beauty aids that can be 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, eyeshadow tips, nail clippers, etc.

The outer cover may be made of a single component, or may be made up of multiple components assembled together.

The outer lid, which is made up of multiple parts, may have a screw-in lid and a cover lid.

In this case, the screw-on lid has lid threads that screw into the container threads.

The cover lid can cover the outside of the screw-on lid, adding a design effect to the airtight container.

《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.

The contents stored in the sealed container of the present invention may be, for example, cosmetics, medicines, food, etc.

Specific embodiments of the sealed container of the present invention will be described in detail below in the form 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.

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

The sealed container (100) of Example 1 is a substantially cylindrical container and has a container body (110), an outer lid (120), an inner lid (130), and a packing (140).

The container body (110) has a contents storage section (115a) and a container peripheral wall (112) that surrounds the contents storage section (115a).

The content storage section (115a) has a substantially circular opening when viewed from above. The peripheral edge of this opening has an upper end (115b) of the opening that protrudes slightly upward from the upper plane (111a) of the container body (110).

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

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). That is, 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 maintaining its state of being attached to the outer lid (120).

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

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

At this time, when the outer lid (120) is gradually screwed into 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 inner 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).

However, as the outer lid (120) continues to be screwed into the container body (110) and the lid screw (121a) and the container screw (114a) are screwed together 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 the two. After that, the inner lid (130) begins to rotate coaxially with the outer lid (120) relative to the outer lid (120).

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 the surface, forming a tight seal between the packing (140) and the upper end (115b) of the opening.

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

The sealed container (200) of Example 2 is a substantially cylindrical container and has a container body (210), an outer lid (220), an inner lid (230), and a packing (240).

Figure 2 shows the state when the outer lid (220) begins to be screwed onto the container body (210), and Figure 3 shows the state when the screws are screwed together and the container is sealed.

The sealed container (200) of Example 2 is a substantially cylindrical container and has a container body (210), an outer lid (220), an inner lid (230), and a packing (240).

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 edge (215b) of the opening;
The upper end (215b) of the opening of the content storage section (215a) is not coaxial with the rotational direction of the container body (210), but an asymmetric element is introduced.
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 to the inside of the outer lid (220) so as to be rotatable coaxially with the outer lid (220), which are similar to the sealed container (100) of Example 1.

However, in the sealed container (200), a recess (213) is formed in a portion of the upper area of the container peripheral wall (212) of the container body (210) that is recessed from the upper flat surface (211a) of the container body (210).

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 convex portion (233) that protrudes inward. This convex portion (233) can be stored in the concave portion (213) of the container body (210).

A packing (240) is attached to a portion of the inner bottom surface (231) of the inner lid. This packing (240) is positioned and sized to form a tight seal between the upper end (215b) of the opening of the content storage section (215a) when the sealed container (200) is in a sealed state.

Therefore, in the sealed container (200) of FIG. 2, when the lid screw (221a) and the container screw (214a) are screwed together and the outer lid (220) is fastened to the container body (210), a seal is formed.

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

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 inner bottom surface (231) of the inner lid (230) is not necessarily in a position where it can form a tight seal between the packing (240) and the upper end (215b) of the opening of the content storage section (215a). Figure 2 shows a state where the positions of the packing (240) and the opening of the content storage section (215a) are not aligned. If the packing (240) moves downward from the position shown in Figure 2, it will not be possible to form a tight seal between the packing (240) and the upper end (215b) of the opening.

However, when the positions of the packing (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 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 from descending and cannot approach the container body (210). Therefore, the lid screw (221a) of the outer lid (220) cannot be screwed into the container screw (214a) of the container body (210).

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 the two, 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).

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 stored 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 a direction that brings them closer to each other. Therefore, the convex portion (233) is stored in the concave portion (213), and 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).

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 consistent positional relationship between the packing (240) and the opening of the content storage section (215a) is generally maintained.

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

Furthermore, as 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 the two, 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 Figure 3).

In the sealed container (200) of Example 2, the content storage section (215a) is not limited to one, and may be two or more. In addition, a secondary storage section may be formed in the container body (210), and appropriate beauty aids may be stored in this secondary storage section.

Example 3
Schematic diagrams of the sealed container of Example 3 are shown in FIGS.

The sealed container (300) of Example 3 is a substantially cylindrical container and has a container body (310), an outer lid (320), an inner lid (330), and a packing (340).

In the sealed container (300) of Example 3, the container body (310) has an inner container portion (311) and an outer container portion (314), and the inner container portion (311) is housed in the outer container portion (314).

The inner container portion (311) of the container body (310) has a content storage section (315a) with 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 end (315b).

In addition, in the sealed container (300) of Example 3, a portion of the upper area of the container peripheral wall (312) surrounding the periphery of the content storage section (315a) has a recess (313) that is recessed from the upper plane (311a) of the container body (310). This recess (313) has an inclined portion where the height from the upper plane (311a) of the container body (310) gradually decreases and then gradually increases.

On the other hand, the outer container portion (314) of the container body (310) has a container thread (314a) that screws into the lid thread (321a) of the outer lid (320).

The remaining configuration of the sealed container (300) of Example 3 is similar to that of the sealed container (200) of Example 2.

Figures 4 to 6 show an example of the shape of the inner lid (330) of the sealed container (300). Figure 4 is a top view of the inner lid (330), Figure 5 is a bottom view, and Figure 6 is a cross-sectional view taken along line A-A.

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 convex portion (333) that protrudes inward. This convex portion (333) can be stored in a concave portion (313) of the outer container portion (314) of the container body (310).

A packing (340) is attached to a portion of the inner bottom surface (331) of the inner lid. This packing (340) is placed in a position and of a size that allows a tight seal to be formed between the packing (340) and the upper end (315b) of the opening of the content storage section (315a) of the inner container portion (311) of the container body (310) when the sealed container (300) is in a sealed state.

Figures 7 to 9 show an example of the state in which the inner lid (330) of the sealed container (300) is attached inside the outer lid (320). Figure 7 is a top view of the outer lid (320) and the inner lid (330), Figure 8 is a bottom view, and Figure 9 is a cross-sectional view along line A-A. The inner lid (330) is attached inside the outer lid (320) so that it can rotate coaxially with the outer lid (320).

Figures 10 to 13 show an example of the shape of the inner container portion (311) of the container body (310) of the sealed container (300). Figure 10 is a top view of the inner container portion (311), Figure 11 is a bottom view, Figure 12 is a cross-sectional view taken along line A-A, and Figure 13 is a perspective view.

The inner container portion (311) in Figures 10 to 13 includes a content storage section (315a) and has a container peripheral wall (312) that surrounds the periphery of the content storage section (315a).

The contents storage section (315a) has a substantially circular opening when viewed from above. The peripheral edge of this opening has an upper end (315b) of the opening that protrudes slightly upward from the upper plane (311a) of the inner container portion (311).

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 area of the upper part of the container peripheral wall (312). This recess (313) has an inclined portion in which the height from the upper plane (331a) of the container body (310) gradually decreases and then gradually increases.

Figures 14 to 17 show an example of a state in which the inner container portion (311) of the container body (310) in the sealed container (300) is housed in the outer container portion (314). Figure 14 is a top view of the inner container portion (311) and the outer container portion (314), Figure 15 is a bottom view, Figure 16 is a cross-sectional view along line A-A, 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 portion (311) and the outer container portion (314).

The upper end (315b) of the opening of the content storage section (315a) of the inner container portion (311) is not coaxial with the direction of rotation of the container body (310). That is, as shown in the cross-sectional view of line A-A in FIG. 16, the rotation axis (A31) of the container body (310) and the central axis (A32) of the content storage section (315a) do not coincide, and an asymmetric element is introduced into the sealed container (300).

Figure 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).

Figures 18 and 19 are schematic cross-sectional views showing the state of the sealed container (300) when the lid begins to be screwed onto the container body (310). In Figure 18, only the inner container part (311), the packing (340), and the inner lid (330) are shown, while in Figure 19, in addition to these, the outer container part (314) and the outer lid (320) are also shown.

When the outer lid (320) and the inner lid (330) are gradually screwed onto the container body (310) from an 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 packing (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 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 from descending and cannot approach the container body (310). Therefore, the lid screw (321a) of the outer lid (320) cannot be screwed into the container screw (314a) of the outer container portion (314).

At this time, the packing (340) is not in contact with the upper end (315b) of the opening of the content storage section (315a), and no frictional force is generated between the two, so 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) will rotate on the container body (310) together with the outer lid (320), 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 storage section (315a) of the inner container part (311).

20 and 21 are schematic cross-sectional views showing the state of 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.

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 in a positional relationship where they match, 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, resulting in a positional relationship where 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 a direction in which they approach each other. Therefore, the convex portion (333) is stored in the concave portion (313), and the outer lid (320) and the inner lid (330) approach the container body (310), and the lid screw (321a) of the outer lid (320) begins to screw into the container screw (314a) of the outer container part (314).

Furthermore, when the convex portion (333) of the inner lid (330) is stored 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 consistent positional relationship between the packing (340) and the opening of the content storage portion (315a) is generally maintained.

Furthermore, as 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 the two, 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 the upper end (315b) rubbing against the surface of the packing (340), forming a tight seal (see Figures 20 and 21).

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

Example 4
Schematic diagrams of the sealed container of Example 4 are shown in FIGS.

The sealed container (400) of Example 4 is a generally cylindrical container with chamfered top and bottom in the axial direction of the cylinder. This sealed container (400) has a container body (410), an outer lid (420), an inner lid (430), and a packing (440).

In the sealed container (400) of Example 4, 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).

The container part for replacing the contents (415) is removably stored in the inner container part (411). By making the container part for replacing the contents (415) removable from the inner container part (411), the sealed container (400) can be reused by replacing the container part for replacing the contents (415) after the contents have been used up with a new container part for replacing the contents (415) filled with the contents.

The content exchange container portion (415) of the container body (410) has a content storage portion (415a) with a substantially circular opening. The peripheral edge of the opening of the content exchange container portion (415) has an upper opening edge (415b).

The inner container portion (411) has a container peripheral wall (412) that surrounds the periphery of the inner container portion (411), and a portion of the upper area of the container peripheral wall (412) has a recess (413) that is recessed from the upper plane (411a) of the inner container portion (411). This recess (413) has an inclined portion where the height from the upper plane (411a) of the inner container portion (411) gradually decreases and then gradually increases.

The outer container portion (414) of the container body (410) has a container thread (414a) that screws into the lid thread (421a) of the screw-on lid (421).

The outer lid (420) of the sealed container (400) of Example 4 has a screw-in lid (421) and a cover lid (422), and the screw-in lid (421) has a lid screw (421a) that screws into the container screw (414a).

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

The remaining configuration of the sealed container (400) of Example 4 is the same as that of the sealed container (300) of Example 3.

Figures 23 to 25 show an example of the shape of the inner lid (430) of the sealed container (400). Figure 23 is a top view of the inner lid (430), Figure 24 is a bottom view, and Figure 25 is a cross-sectional view taken along line A-A.

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 convex portion (433) that protrudes inward. This convex portion (433) can be stored in a concave portion (413) of the inner container portion (411) of the container body (410).

A packing (440) is attached to a portion of the inner bottom surface (431) of the inner lid. This packing (440) is placed in a position and of a size that allows a tight seal to be formed 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.

Figures 26 to 28 show an example of the state in which the inner lid (430) of the sealed container (400) is attached inside the screw-on lid (421) of the outer lid (420). Figure 26 is a top view of the screw-on lid (421) and the inner lid (430), Figure 27 is a bottom view, and Figure 28 is a cross-sectional view along line A-A. The inner lid (430) is attached inside the screw-on lid (421) so that it can rotate coaxially with the screw-on lid (421). Therefore, the inner lid (430) can also rotate coaxially with respect to the outer lid (420).

Figures 29 to 31 show the cover lid (422) together with the inner lid (430) and the screw-in lid (421). Figure 29 is a top view of the screw-in lid (421), cover lid (422), and inner lid (430), Figure 30 is a bottom view, and Figure 31 is a cross-sectional view along line A-A. As can be seen in these figures, the outer lid (420) of the airtight container (400) includes the screw-in lid (421) and the cover lid (422).

Figures 32 to 35 show an example of the shape of the inner container portion (411) of the container body (410) of the sealed container (400). Figure 32 is a top view of the inner container portion (411), Figure 33 is a bottom view, Figure 34 is a cross-sectional view taken along line A-A, and Figure 35 is a perspective view.

The inner container portion (411) of Figures 32 to 35 has a recessed recess (413) in a partial area of the upper part of the container peripheral wall (412). This recess (413) has a sloping portion in which the height from the upper plane (411a) of the inner container portion (411) gradually decreases and then gradually increases.

Figures 36 to 39 show the state in which the content replacement container part (415) is stored in the inner container part (411). Figure 36 is a top view of the inner container part (411) and the content replacement container part (415), Figure 37 is a bottom view, Figure 38 is a cross-sectional view along line A-A, and Figure 39 is a perspective view.

In Figures 36 to 39, the content exchange container portion (415) is provided with a content storage section (415a). This content storage section (415a) may have a substantially circular opening when viewed from above, and the peripheral edge of this opening forms the opening upper end (415b). This 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).

Figure 38 shows that a gap (416) is formed between the outside of the content exchange container portion (415) and the inside of the inner container portion (411). As shown in Figure 42 below, this gap (416) is formed on the side farther from the central axis (A42) of the content storage portion (415a) with respect to the rotation axis (A41) of the container body (410).

Figures 40 to 43 show an example of the state in which the inner container portion (411) and the container portion for replacing contents (415) of the container body (410) in the sealed container (400) are stored in the outer container portion (414). Figure 40 is a top view of the inner container portion (411), the container portion for replacing contents (415), and the outer container portion (414), Figure 41 is a bottom view, Figure 42 is a cross-sectional view along line A-A, and Figure 43 is a perspective view. With reference to Figures 42 and 43, it can be seen that the container body (410) is composed of the inner container portion (411), the container portion for replacing contents (415), and the outer container portion (414).

The upper end (415b) of the opening of the contents storage section (415a) of the contents 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 A-A in FIG. 42, the rotational axis (A41) of the container body (410) and the central axis (A42) of the contents storage section (415a) do not coincide, and an asymmetric element is introduced into the sealed container (400).

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). In Figure 44, only the inner container part (411), the container part for replacing contents (415), the packing (440), and the inner lid (430) are shown, while in Figure 45, in addition to these, the outer container part (414) and the lid for screwing (421) are also shown. The lid for covering is not shown in Figures 44 and 45.

When the screw-on lid (421) and the inner lid (430) are gradually screwed into the container body (410) from an 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 packing (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 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 from descending 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).

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 the two, so 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 on the container body (410) together with the screw-in lid (421), 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).

Figures 46 and 47 are schematic cross-sectional views showing the state of the sealed container (400) when the position of the packing (440) and the position of the opening of the content storage section (415a) are in a positional relationship that aligns them. In Figure 46, only the inner container part (411), the content exchange container part (415), the packing (440), and the inner lid (430) are shown, while in Figure 47, in addition to these, the outer container part (414) and the screw-on lid (421) are also shown. The cover lid is not shown in Figures 46 and 47.

In this airtight container (400), when the position of the packing (440) and the position of the opening of the content storage section (415a) are in a positional relationship where they match, 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, resulting in a positional relationship where the convex portion (433) of the inner lid (430) can be stored 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-in lid (421) and the inner lid (430) in a direction in which they approach each other. Therefore, the convex portion (433) is stored in the concave portion (413), and the screw-on lid (421) and the inner lid (430) approach the container body (410), and the lid thread (421a) of the screw-on lid (421) begins to screw into the container thread (414a) of the outer container part (414).

Furthermore, when the convex portion (433) of the inner lid (430) is stored 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 consistent positional relationship between the packing (440) and the opening of the content storage portion (415a) is generally maintained.

Furthermore, as the screw-in lid (421) continues to rotate and the lid screw (421a) and container screw (414a) are screwed together 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 the two, 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).

In the sealed container (400) of Example 4, a gap may be formed between the outside of the container portion for replacing the contents and the inside of the inner container portion, and a spatula may be stored in this gap. Figure 48 shows a state in which a spatula (450) is stored in the gap (416) formed between the outside of the container portion for replacing the contents (415) and the inside of the inner container portion (411) of the sealed container (400). In Figure 48, a cover lid (422) is also shown.
