Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above-mentioned document, the lid member is put on from above the PET bottle (see FIG. 4). Then, the female screw portion of the lid member is screwed into the male screw portion of the storage container body and screwed downward. When the elastic member abuts on the outer periphery of the middle part of the shoulder of the PET bottle, the screwing is stopped (see FIGS. 1 and 2). When screwing the lid member and the storage container body together, there is a problem that the number of rotations is large. On one side, the present invention aims to reduce the number of rotations during screwing. [[ID=3又9]]

[Modes for carrying out the invention]

[0008] The storage container of this embodiment will be described in detail below with reference to the drawings. The positions, sizes, shapes, and ranges of the components shown in the following drawings may not represent their actual positions, sizes, shapes, and ranges in order to facilitate understanding of the invention. Therefore, the present invention is not necessarily limited to the positions, sizes, shapes, and ranges disclosed in the drawings. In the embodiments, elements expressed in the singular form shall include the plural form unless otherwise clearly indicated in the text. <Embodiment>

[0009] Figure 1 is a perspective view showing the storage container of the embodiment. Figure 2 is an exploded perspective view showing the storage container of the embodiment. Figure 3 is a cross-sectional view illustrating an example of use of the storage container of the embodiment. As shown in Figure 2, the storage container 100 of this embodiment has a container body 1 having an annular first opening 11 and a lid portion 2. A screw-on portion 12 is positioned near the first opening 11. The container body 1 is, for example, a cylindrical shape with a bottom and has a vacuum double-wall structure that provides insulation. Examples of materials used to make up the container body 1 include stainless steel.

[0010] As shown in Figure 3, the container body 1 can store beverage containers (such as PET bottles or glass bottles). In this embodiment, we will describe the case where a PET bottle 50 is stored. As shown in Figure 2, the lid portion 2 has a main body portion 21 and a protruding portion 22. Examples of materials used to make up the lid portion 2 include resin. The main body 21 is roughly cylindrical in shape.

[0011] The protruding portion 22 is cylindrical and continuous with the main body portion 21, and in Figure 2, it protrudes above the main body portion 21. A second opening 22a is provided in the central part of this protruding portion 22. The second opening 22a is an annular shape with 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 with which a part of the plastic bottle 50 abuts is attached around the second opening 22a. In FIG. 3, the tapered portion (shoulder portion) of the plastic bottle 50 abuts on the contact portion 22b. The contact portion 22b is an annular elastic member. The elastic member is not particularly limited, and examples thereof include rubber, synthetic rubber, and soft plastic resin.

[0013] As shown in FIG. 3, in the present embodiment, the cross-sectional shape of the protruding portion 22 protruding from the main body portion 21 is curved inward, but it may be curved outward, may be bent, or may be linear. As shown in FIG. 3, a threaded portion 23 that is screwed into the threaded portion 12 is provided on the inner side portion of the main body portion 21. FIG. 4 is a diagram for explaining the threaded portion of the container body of the embodiment.

[0014] The threaded portion 12 has three long convex portions 12a, 12b, and 12c having the same shape that form the threaded portion 12. Each end portion 12a 1, 12b 1, 12c 1 on the tip side when viewed from the screwing direction (counterclockwise direction) of these convex portions 12a, 12b, 12c is arranged at intervals of 120 degrees in plan view. FIG. 5 is a diagram for explaining the threaded portion of the lid portion of the embodiment.

[0015] The threaded portion 23 has three long convex portions 23a, 23b, and 23c having the same shape that form the threaded portion 23. Each end portion 23a 1, 23b 1, 23c 1 on the tip side when viewed from the screwing direction (counterclockwise direction) of these convex portions 23a, 23b, 23c is arranged at intervals of 120 degrees in plan view. Next, an example of the usage method of the storage container 100 will be described.

[0016] The user places a PET bottle 50 into the container body 1 and attaches the lid 2. When attaching, the lid 2 is rotated relative to the container body 1, causing the threaded portion 23 to screw onto the threaded portion 12. At this time, as mentioned 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, for example, a storage container where the ends are arranged at 180-degree intervals in a plan view, the lid 2 can reach the position where it can no longer be screwed (stop position) with fewer rotations when the threaded portion 23 is screwed onto the threaded portion 12. Figure 6 illustrates the stopping position when there is no plastic bottle present. 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. Figure 7 illustrates the stopping position when a PET bottle is placed in a storage container.

[0017] By rotating the lid 2 relative to the container body 1 to a certain extent, the shoulder portion 51 of the PET bottle 50 comes into contact with the contact portion 22b. This position becomes the stopping position of the lid 2. As a result, most of the PET bottle 50 is stored in the container body 1, improving its ability to keep things cold or hot. When the lid 2 is attached to the container body 1, the contact portion 22b, which is provided around the second opening 22a, comes into contact with a point midway along the shoulder portion 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. The contact portion 22b is also made of an elastic material. Therefore, when the user opens and closes the lid of the PET bottle 50 (when rotated), the friction acting between the contact portion 22b and the shoulder portion 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 storing a PET bottle that differs in the shape and height of its shoulder portion 51 from the PET bottle 50, the position in which the lid is attached to the container body 1 by screwing it in may change. Figure 8 illustrates the stopping positions when PET bottles of different heights are stored in a storage container. The PET bottle 50a shown in Figure 8 has a greater height from the bottom to the shoulder compared to the PET bottle 50 shown in Figure 7.

[0018] Even when storing such a PET bottle 50a, the contact portion 22b contacts the outer circumference of the shoulder portion, thus suppressing rattling of the PET bottle 51 relative to the storage container 100, similar to the PET bottle 50. Furthermore, as mentioned above, opening and closing the lid of the PET bottle 50 is easy.

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

[0020] Next, a modified example of the storage container of the embodiment will be described. The modified storage container differs from the storage container 100 in the shape of the threaded portion 12 and the threaded portion 23, but is otherwise the same as the storage container 100. Figure 9 illustrates the threaded portion of the container body in a modified example.

[0021] The modified screw-to-screw portion 12 has four elongated protrusions 12d, 12e, 12f, and 12g of the same shape that form the screw-to-screw portion 12. When viewed from the screw-in direction (counterclockwise direction), the respective end portions 12d1, 12e1, 12f1, and 12g1 of these protrusions 12d, 12e, 12f, and 12g1 are arranged at 90-degree intervals in a plan view. Figure 10 illustrates the threaded portion of the lid in a modified example.

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

[0023] This modified container provides the same effect as container 100. Furthermore, this modified container allows for a reduction in 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. Furthermore, other arbitrary components or processes may be added to the present invention. Furthermore, the present invention may be a combination of any two or more configurations (features) from the embodiments described above. [Explanation of Symbols]
