[0008] Hereinafter, a storage container according to an embodiment will be described in detail with reference to the drawings. In order to facilitate understanding of the invention, the position, size, shape, range, etc. of each component shown in the following drawings may not represent the actual position, size, shape, range, etc. Therefore, the present invention is not necessarily limited to the position, size, shape, range, etc. disclosed in the drawings, etc. In the embodiments, elements expressed in the singular form include the plural form unless otherwise clearly indicated in the context. <Embodiment Mode>

[0009] Fig. 1 is a perspective view showing a storage container according to an embodiment, Fig. 2 is an exploded perspective view showing a storage container according to an embodiment, and Fig. 3 is a cross-sectional view explaining an example of use of the storage container according to an embodiment. 2, the storage container 100 of the embodiment has a container body 1 having a circular first opening 11, and a lid 2. A screwed portion 12 is disposed near the first opening 11. The container body 1 is, for example, cylindrical with a bottom and has a vacuum double-wall structure with a cold insulation function. Examples of the material of the container body 1 include stainless steel.

[0010] 3, a beverage container (such as a plastic bottle or a glass bottle) can be stored in the container body 1. In this embodiment, a description will be given of a container body that stores a plastic bottle 50. 2, the lid portion 2 has a main body portion 21 and a protruding portion 22. The lid portion 2 may be made of a material such as resin. The main body 21 has a generally circular tubular shape.

[0011] The protruding portion 22 is cylindrical and connected to the main body portion 21, and protrudes upward from the main body portion 21 in FIG. 2. A second opening 22a is provided in the center of the protruding portion 22. The second opening 22a is annular and has a smaller diameter than the first opening 11.

[0012] The second opening 22a is located above the first opening 11. As shown in Fig. 3, a contact portion 22b against which a part of the plastic bottle 50 contacts is attached around the second opening 22a. In Fig. 3, the tapered portion (shoulder portion) of the plastic bottle 50 contacts the contact portion 22b. The contact portion 22b is an annular elastic member. The elastic member is not particularly limited, but examples thereof include rubber, synthetic rubber, soft plastic resin, etc.

[0013] As shown in FIG. 3, in this embodiment, the cross-sectional shape of the protrusion 22 protruding from the main body 21 is an inwardly curved shape, but it may also be an outwardly curved shape, a bent shape, or a straight shape. As shown in FIG. 3, a screw portion 23 that screws into the screwed portion 12 is provided on the inner side of the main body portion 21. FIG. 4 is a diagram illustrating a screwed portion of a container body according to an embodiment.

[0014] The screwed portion 12 has three elongated convex portions 12a, 12b, and 12c of the same shape that form the screwed portion 12. End portions 12a1, 12b1, and 12c1 on the tip side as viewed from the screwing direction (counterclockwise direction) of these convex portions 12a, 12b, and 12c are arranged at 120 degree intervals in a plan view. FIG. 5 is a diagram illustrating a screw-on portion of the lid according to the embodiment.

[0015] The screw-engaging portion 23 has three elongated protrusions 23a, 23b, and 23c of the same shape that form the screw-engaging portion 23. Ends 23a1, 23b1, and 23c1 on the tip side as viewed from the screw-in direction (counterclockwise direction) of these protrusions 23a, 23b, and 23c are arranged at 120 degree intervals in a plan view. Next, an example of a method of using the storage container 100 will be described.

[0016] A user stores a plastic bottle 50 in the container body 1 and attaches the lid part 2. When attaching, the lid part 2 is rotated relative to the container body 1, so that the screwing part 23 is screwed into the screwed part 12. At this time, as described above, the ends 12a1, 12b1, and 12c1 are arranged at 120 degree intervals in a plan view. Also, the ends 23a1, 23b1, and 23c1 are arranged at 120 degree intervals in a plan view. Therefore, compared to a storage container or the like in which the ends are arranged at 180 degree intervals in a plan view, when the screwing part 23 is screwed into the screwed part 12, the lid part 2 can reach a position (stop position) where it will not screw any further with a smaller number of rotations. FIG. 6 is a diagram for explaining the stopping position when there is no plastic bottle. When there is no plastic bottle, the position where the opening 11 abuts against the base end 22c of the protruding portion 22 of the lid portion 2 becomes the stopping position of the lid portion 2. FIG. 7 is a diagram for explaining the stopping position when the plastic bottle is stored in the storage container.

[0017] By rotating the lid 2 to a certain extent relative to the container body 1, the shoulder 51 of the PET bottle 50 comes into contact with the abutment 22b. This position is the stop position of the lid 2. As a result, most of the PET bottle 50 is stored in the container body 1, improving the cold and heat retention. In addition, when the lid 2 is attached to the container body 1, the abutment 22b provided around the second opening 22a comes into contact with the middle part of the shoulder 51 of the PET bottle 50. Therefore, even if the storage container 100 is shaken, the rattling of the PET bottle 50 relative to the storage container 100 is suppressed. In addition, the abutment 22b is formed of an elastic material. Therefore, when a user opens or closes the lid of the PET bottle 50 (when rotating it), the friction acting between the abutment 22b and the shoulder of the PET bottle 50 prevents the PET bottle 50 from spinning freely, making it easy to open and close the lid of the PET bottle 50. Furthermore, when a plastic bottle having a shoulder portion 51 with a different shape or height from that of the plastic bottle 50 is stored, the mounting position of the lid portion screwed onto the container body 1 may change. FIG. 8 is a diagram for explaining the stopping positions when plastic bottles of different heights are stored in the storage container. A plastic bottle 50a shown in FIG. 8 is taller from the bottom to the shoulder than the plastic bottle 50 shown in FIG.

[0018] Even when such a plastic bottle 50a is stored, the abutment portion 22b abuts against the outer periphery of the middle part of the shoulder, so that rattling of the plastic bottle 51 relative to the storage container 100 is suppressed, similar to the plastic bottle 50. Also, as described above, the lid of the plastic bottle 50 can be easily opened and closed.

[0019] As described above, the storage container 100 of the embodiment has a bottomed cylindrical annular first opening 11 and a screwed portion 12 provided near the first opening 11, a container body 1 in which a plastic bottle 50 is stored, and a cylindrical lid portion 2 having a screwing portion 23 that screws into the screwed portion 12, and ends 12a1, 12b1, and 12c1 of the long protrusions 12a, 12b, and 12c that form the screwed portion 12 are arranged at 120 degree intervals in a plan view, and ends 23a1, 23b1, and 23c1 of the long protrusions 23a, 23b, and 23c that form the screwed portion 23 are arranged at 120 degree intervals in a plan view. Therefore, the number of rotations during screwing can be reduced. <Modification>

[0020] Next, a modified example of the storage container of the embodiment will be described. The modified storage container is similar to storage container 100 except for the shapes of screwed portion 12 and screw portion 23. FIG. 9 is a diagram illustrating a screwed portion of a container body according to a modified example.

[0021] The screwed portion 12 of the modified example has four elongated convex portions 12d, 12e, 12f, and 12g of the same shape that form the screwed portion 12. End portions 12d1, 12e1, 12f1, and 12g1 on the tip side as viewed from the screwing direction (counterclockwise direction) of these convex portions 12d, 12e, 12f, and 12g are arranged at 90 degree intervals in a plan view. FIG. 10 is a diagram illustrating a screw-on portion of a lid portion according to a modified example.

[0022] The screw-engaging portion 23 has four elongated protrusions 23d, 23e, 23f, and 23g of the same shape that form the screw-engaging portion 23. Ends 23d1, 23e1, 23f1, and 23g1 on the tip side as viewed from the screw-in direction (counterclockwise direction) of these protrusions 23d, 23e, 23f, and 23g are arranged at 90 degree intervals in a plan view.

[0023] According to this modified storage container, it is possible to obtain the same effects as those of storage container 100. Moreover, according to the modified storage container, it is possible to further reduce the number of rotations required during screwing.

[0024] Although the storage container of the present invention has been described above based on the illustrated embodiment, the present invention is not limited thereto, and the configuration of each part can be replaced with any configuration having a similar function. In addition, any other configuration or process can be added to the present invention. Furthermore, the present invention may be a combination of any two or more configurations (features) of the respective embodiments described above. [Explanation of symbols]
