Description

[Technical field]

[0001] The present invention relates to a container auxiliary device that is placed on a general-purpose container and that can easily increase the storage capacity of items contained in the container. [Background technology]

[0002] Containers, which are box-shaped storage containers, are widely used in a variety of fields, including ordinary homes, factories, agriculture, and the fishing industry. In addition, multiple commercially available containers can be stacked, making them highly convenient in terms of transportation and storage.

[0003] However, when general-purpose containers contain items that are taller than the container, other containers cannot be stacked on top of them, so the only way to store or transport them is to stack the containers flat.

[0004] To solve these problems, there is a container volume increasing frame that is placed on the top surface of a transport and storage container to increase the internal volume of the container (see, for example, Patent Document 1).

[0005] The container volume increasing mouth frame of the above-mentioned Patent Document 1 is an annular container volume increasing mouth frame placed on the upper flange (2) of the container body (1), characterized in that the mouth frame (3) is formed from a plurality of peripheral wall members (3a, 3b), connecting portions (88a, 8b, 13, 15) are provided at the ends of each peripheral wall member (3a, 3b), and the connecting portions (88a, 8b, 13, 15) are detachably fitted and fixed to each other to form an annular shape.

[0006] However, in order to make the opening frame for increasing the internal volume of the container in Patent Document 1 detachable and attachable to a general-purpose container, it is necessary to process and attach connecting parts, fitting parts, and connecting parts, etc., which leads to high material and manufacturing costs as well as making the work more difficult.

[0007] In view of the above, the present invention has an object to provide a container auxiliary device that is placed on a general-purpose container, and in particular, a container auxiliary device that can easily increase the amount of items stored in the container.

[0008] In order to solve the above problems, the container auxiliary device of the present invention comprises a top opening, a bottom opening, and a side portion arranged between the top opening and the bottom opening, and is characterized in that the bottom opening is formed with a bottom engagement portion that engages with the top opening of a general-purpose container.

[0009] In addition, an upper engaging portion is formed at the top opening to engage with the bottom portion of a general-purpose container.

[0010] By forming a bottom engaging portion at the bottom opening that engages with the top opening of a general-purpose container, the amount of items stored in the container can be easily increased simply by placing the container auxiliary device on the top opening of the general-purpose container.

[0011] Furthermore, by forming an upper engaging portion at the upper opening for engaging with the bottom portion of a general-purpose container, a plurality of container support devices and general-purpose containers can be stacked. [Brief description of the drawings]

[0013] The container auxiliary device of the present invention is a container auxiliary device that is placed on a general-purpose container, and is particularly characterized by its ability to easily increase the amount of items that can be stored in the container. The container auxiliary device of the present invention will be described in detail below with reference to the drawings.

[0014] The illustrated container auxiliary tool 1 is placed on top of a general-purpose container 10 that is widely used in a variety of fields, including ordinary homes, factories, agriculture, and the fishing industry. The container auxiliary tool 1 comprises a top opening 2, a bottom opening 3, and a side portion 4 that is disposed between the top opening 2 and the bottom opening 3.

[0015] The container auxiliary tool 1 is preferably made of the same material as the general-purpose container 10, and is formed to have the same dimensions in the vertical and width directions. Also, the opposing side portions 4 are provided with openings 5 ​​for inserting handles.

[0016] In particular, the container auxiliary device 1 of the present invention is characterized in that the bottom opening 3 is formed with a bottom engaging portion 6 that engages with the top opening 11 of a general-purpose container 10, as shown in Figure 2.

[0017] The bottom engaging portion 6 has a structure in which only the bottom plate of the bottom of a general-purpose container 10 has been removed. Therefore, a large bottom opening 3 is formed in the bottom of the container auxiliary tool 1 of the present invention.

[0018] Additionally, around the top opening 2 of the container auxiliary device 1 of the present invention, a top engaging portion 7 having the same shape as the top opening 11 of the general-purpose container 10 is formed. Furthermore, around the bottom opening 3 of the container auxiliary device 1, a bottom engaging portion 6 that engages with the top opening 11 of the general-purpose container 10 is formed.

[0019] With the above-mentioned structure, as shown in Figures 3 and 4, by arranging the bottom engaging portion 6 of the container auxiliary device 1 of the present invention above the top opening 11 of a general-purpose container 10, the container auxiliary device 1 can be placed on the top of the general-purpose container 10. In this state, the amount of items stored in the container 10 can be easily increased.

[0020] Next, a method of using the container auxiliary device 1 of the present invention will be described with reference to FIGS. FIG. 5 shows a general-purpose container 10 with a large amount of items (vegetables) A ​​stored therein.

[0021] In this case, the stored item A protrudes upward from the top opening 11 of the container 10. In this state, general-purpose containers 10 cannot be stacked on top. Therefore, when the containers are moved by truck or stored in a storeroom, they are stacked flat, which makes it difficult to use the area effectively.

[0022] In the above-mentioned state, as shown in Fig. 6, by placing the bottom opening 6 of the container auxiliary tool 1 of the present invention above the top opening 11 of a general-purpose container 10, the protruding stored items (vegetables) A ​​can be covered by the container auxiliary tool 1. In addition, since the general-purpose container 10 can be stacked on the top engagement part 7 of the container auxiliary tool 1, the area can be used effectively.

[0023] Furthermore, by stacking multiple container auxiliary devices 1 of the present invention in the upper opening 11 of a general-purpose container 10, even long items can be easily stored, making it more convenient for transporting and storing.

[0024] With the above-mentioned structure, the amount of items stored in a container can be easily increased simply by placing the container auxiliary device 1 on the top opening 11 of a general-purpose container 10. In addition, by forming the top engaging portion 7 on the top opening 2, which engages with the bottom portion 12 of the general-purpose container 10, multiple container auxiliary devices 10 can be stacked.
