Abstract

PROBLEM TO BE SOLVED: To provide an extendable bottle in which a surplus space generated in response to a reduction of drinking water within a container is eliminated by adjusting a size (a height) of the container, perform an efficient storing of the bottle, enable the bottles to be stacked on each other and further enable a storing location for the bottle to be eliminated. SOLUTION: A lid 3 is arranged at an opening part of a container composed of bellows. In the case that there are more than two containers, a pouring port 5 of another container can be inserted into an insertion hole 6 arranged at a bottom part 7 of a container comprised of bellows and then the containers can be stacked up on each other.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container whose size can be adjusted by expanding and contracting and which can be stacked, particularly a container mainly used for beverages.

[0002]

2. Description of the Related Art In the art of changing the size of a container, there is known a technology in which the container body is formed in a bellows shape and is molded by plastic molding. Although it is excellent in changing the length (length), shape (direction), etc., it does not employ a mechanism for stacking and using a plurality of containers.

[0003]

This has the following disadvantages. I. When I went out with drinking water in a container such as a water bottle, when I drank all the drinking water, the empty container became a useless luggage to take home. B. When drinking water such as barley tea was stored in a container in a refrigerator, extra space was created in the container as much as the amount of drinking water was reduced, and waste was taken in the refrigerator. . C. When storing it when not in use, it took a place unexpectedly, so it was in the way.

[0004]

A container comprising a bellows (1)
Is formed as an opening (2), a lid (3) is provided according to the container diameter of the opening (2), and the lid (3) has an inlet (4) with a cap (4). 5) is formed, and an insertion hole (6) is formed in the container bottom (7) so that the container can be fitted into an inlet when a plurality of containers are stacked. The present invention is a container having the above configuration.

[0005]

Embodiments of the present invention will be described below. (A) A lid (3) is provided in an opening (2) at the upper part of a container (1) made of bellows. (B) An inlet (5) with a cap (4) is provided above the lid (3). (C) an insertion hole (6) large enough to fit the inlet (5) of the container (1) made of bellows into the bottom (7) of the container;
Is provided. Hereinafter, specific examples of shapes and materials that are considered to be most suitable for the present invention will be described. (A) The material of the container (1) made of bellows is desirably made of somewhat hard plastic. (B) The materials of the lid (3), the cap (4), and the injection port (5) are desirably plastic. (C) The connection between the container (1) made of bellows and the lid (3)
In addition to the screw-in type, a fitting type may be considered. (D) The connection between the injection port (5) and the cap (4) may be a screw type or a fitting type. (E) Regarding the fitting of the injection port (5) and the insertion hole (6), the shape of the injection port (5) is cylindrical, and the central part may be slightly swelled as compared with the upper and lower parts. The insertion hole (6) is a portion shown in black in FIG. 4 and has a structure in which the lowermost layer of elasticity has a depth (thickness). It is the same size as the inlet (5). This is required because when the inlet of one container is fitted into the insertion hole of the other container, the fitting is firm and provides more stability. Further, a similar function can be achieved by providing a groove in the body portion of the injection port in the circumferential direction and inserting the insertion hole of another container into this portion. The present invention has the above configuration, and when used, the size of the container (1) composed of the bellows of the present invention is reduced by adjusting the size of the bellows of the present invention by the reduced amount of drinking water in the container of the present invention. Or shrink. By providing an inlet (5) and an insertion hole (6) of the same size in the bottom (7) of the container (1) made of bellows, two or more of the present invention containing drinking water in a refrigerator are provided. In some cases, when the amount of drinking water in each container of the present invention is reduced, the inlet (5) of one container and the insertion hole (6) of the other container are fitted and stacked in tandem. In addition, when there are several present inventions in storage when not in use, the present invention is folded down to the smallest size and each is fitted.

[0006]

According to the present invention, the size of the container can be adjusted in accordance with the amount of the contents of the container, the extra space in the container can be eliminated, and the storage can be performed efficiently. In addition, when the contents are emptied for carrying when going out, it is convenient to take home if all the containers of the present invention are folded. Furthermore, stacking is possible during storage in a refrigerator or the like. In addition, because it can be expanded and contracted,
Eliminating the storage space when not in use is solved.
