Description

The present invention relates to a transport opening / closing container, a transport unit, and a transport unit with a built-in article that can be used for storing articles and manually transporting articles.

In recent years, there has been a growing movement to keep food, drinking water containers, and other stockpiled items in the storage areas secured in buildings such as houses, public facilities, and private business establishments in case of disasters such as earthquakes and floods.
The stockpiled goods are taken out from the storage place of the building in the disaster area and used, or transported from a remote place to the disaster area by a truck or the like and provided.
When a large-scale disaster such as an earthquake or flood creates an area where it is difficult for vehicles to pass, it is often the case that the stockpiled goods are transported to the destination where it is difficult for trucks to travel by human power. When manually transporting stockpiled goods to a place several hundred meters to several kilometers away, there is a strong need to use a bag with a shoulder strap such as a rucksack (backpack) in terms of reducing the transportation labor.

For the transportation of liquids such as drinking water and fuel, for example, the container (water container) described in Patent Document 1 can also be adopted. The container described in Patent Document 1 has a container body that can be folded into a small size when no liquid is stored, a case body that is flexibly and foldably formed by a cloth or the like to store the container body, and an open top surface of the case body. It has a case lid that can be attached to and detached from the portion, and a shoulder strap (shoulder belt) attached to the case body.

As shown in FIG. 6, in the article-embedded transport unit 100A in the state of being carried on the back, the ball string 12 covers the article storage section 20 with respect to the storage section bottom plate 22a by the binding force that restrains the opening / closing cover section 30 to the article storage section 20. The overlapped state of the main plate 31 can be stably maintained.
The opening / closing cover portion 30 in which the cover portion main plate 31 is superposed on the storage portion bottom plate 22a of the article storage portion 20 suppresses the deformation of the storage portion bottom plate 22a, and the shape of the article storage portion 20 of the article built-in transport unit 100A in the state of carrying the article on the back. Stability can be improved. The opening / closing cover portion 30 in which the cover portion main plate 31 is superposed on the storage portion bottom plate 22a of the article storage portion 20 enhances the stability of the center of gravity of the article built-in transport unit 100A carried by the user H, and further enhances the transportation labor of the article P. Effectively contributes to the reduction of.

As shown in FIGS. 7A and 7B, the opening / closing cover portion 30 of the article-embedded transport unit 100A in the state of being carried on the back carries the article-embedded transport unit 100A on the back by the user H using the shoulder strap 91. It is located on the lower side of the article storage unit 20 at the time. Further, at this time, as shown in FIG. 6 and the like, the cover portion top plate 32a of the opening / closing cover portion 30 is arranged on the extension of the back support plate 21 of the article storage portion 20 in the same direction as the back support plate 21.

When the user H hangs the shoulder strap 91 on his / her shoulder and carries the article-embedded transport unit 100A in the state of carrying the article on his / her back, the weight of the transport opening / closing container 10 itself is placed in the transport opening / closing container 10 of the article-embedded transport unit 100A. And, depending on the weight of the article P in the article storage portion 20, a rotational force in a direction in which the lower side from the upper end portion of the back support plate 21 presses the user H from the back side acts around the upper end portion of the back support plate 21.
If the opening / closing cover portion 30 does not exist under the article storage portion 20, this rotational force may act as a pressing force for pressing the back of the user H from the lower end of the back support plate 21.

Therefore, when the user H carries the article-embedded transport unit 100A in the state of being carried on his back, the user H is pressed from the lower end of the transport opening / closing container 10 (here, the lower end of the cover portion top plate 32a). The magnitude of the acting rotational force is smaller than the rotational force acting to press the back to the user H from the lower end of the backing plate 21 when the opening / closing cover portion 30 is not present under the article storage portion 20.

In many cases, the rotational force of the transport opening / closing container 10 carried by the user H using the shoulder strap 91 locally acts on the user H only from the lower end of the transport opening / closing container 10. Therefore, if the rotational force acting on the user H from the lower end of the transport opening / closing container 10 is large, it becomes difficult to carry the transport opening / closing container 10 on the back. The rotational force acting on the user H from the lower end of the transport opening / closing container 10 carried by the user H using the shoulder strap 91 is the weight of the transport opening / closing container 10 itself and the stored items (article P, etc.) inside the transport opening / closing container 10. The larger the total weight of, the larger.
Since the article-embedded transport unit 100A in the state of being carried on the back can suppress the rotational force acting on the user H from the lower end of the transport opening / closing container 10 (the lower end of the cover portion top plate 32a), the transport opening / closing container 10 is not difficult to carry. It is advantageous to increase the weight of the article P to be stored in the article storage unit 20 within the range.
