By the way, in the case of the container of Patent Document 1, when closing the door portion that is in the open state as described above, it is difficult to put a hand on the door portion, and it is difficult to close the door portion. It is feared that it will be relatively difficult to In particular, when the container is relatively large, the door may become relatively heavy, and the work of closing the door may become even more difficult.

SUMMARY OF THE INVENTION The present invention has been made to solve the problems exemplified above, and an object of the present invention is to provide a container capable of improving the workability of closing the door from the open state. That's what it is.

Hereinafter, each means suitable for solving the above problems will be described separately. It should be noted that actions and effects specific to the corresponding means will be added as necessary.

Means 1. A container comprising a bottom wall-constituting portion having a substantially rectangular shape in plan view and side wall portions extending upward from respective side portions of the bottom wall-constituting portion,
The side wall portion includes a side wall body provided with an opening penetrating in a thickness direction, and a door portion capable of changing its state between an open state for opening the opening and a closed state for closing the opening. Equipped with a side wall with a door,
The door portion is rotatably connected to a lower edge portion of the opening of the side wall main body so as to be openable to the outside of the container,
When the door portion is in the open state, the outer surface of the door portion faces the outer surface of the side wall body and abuts or comes close to the outer surface of the side wall main body, and the upper side portion of the door portion A configuration arranged on the lower side of the part,
At least one of the outer surface of the side wall main body of the side wall portion with the door and the outer surface of the bottom wall forming portion adjacent to the lower side of the outer surface of the side wall main portion is provided with an upper side portion of the opened door portion. A handle facing portion recessed on the side away from the opened door portion is provided so as to form a space between the
The handle facing portion includes a communicating portion that communicates between the space portion and a space below the opened door portion when the door portion is opened. ,
A notch is provided at the upper end of the outer surface of the door,
A container, wherein when the door portion is in the open state, a portion of the door portion provided with the notch portion and the handle facing portion are arranged to face each other.

According to the means 1, when the door portion in the open state is closed, the space portion is formed between the outer surface of the door portion and the portion facing the handle via the communicating portion of the portion facing the handle. By inserting a finger into the opening and placing the finger on the outer surface of the door portion, the peripheral portion of the upper side portion of the door portion located on the lower side of the door portion can be firmly grasped. In other words, when the door portion in the open state is lifted to the closed state side, the operation of placing a finger on the outer surface of the door portion can be performed relatively smoothly without putting a burden on the finger. Since the door portion in the open state can be suitably grasped from the start of the work to close the door portion in the open state, the hand slips from the door portion when trying to lift the door portion in the open state. Such a situation can be prevented.

Further, when opening the door portion from the closed state, the finger is positioned in the space, so that the door portion contacts or comes close to the outer surface of the side wall main body. It is possible to keep a finger on the outer surface side of the part. For this reason, a finger may be caught between the opened door portion and the handle facing portion, or when opening the door portion, the outer surface of the door portion and the outer surface of the side wall main body may become displaced. Defects caused by releasing the hand from the door when it is relatively separated (damage to the door, the side wall body, the bottom wall structure, and the part that supports the door, and the rebound of the door to the operator) It is possible to prevent situations such as

Therefore, the door can be opened and closed relatively smoothly and more safely, and workability can be improved. In particular, when the container is relatively large and the door portion is relatively heavy, such effects are more pronounced.
In addition, the space formed between the portion facing the handle and the upper side portion of the open door portion can be expanded to the door portion side. Furthermore, it is possible to widen the entrance of the finger to the space including the communicating portion. Therefore, it is possible to secure a wider space in a more suitable manner. It is possible to avoid a situation in which the change in the shape of the peripheral portion facing the handle becomes large, resulting in a decrease in strength or the like.

Means 2. In means 1, the handle-facing portion is provided with a guide surface portion that extends continuously from the communication portion to a portion corresponding to the space portion and has no step in the lateral width direction of the side wall portion with the door. container as described.

According to the means 2, when closing the door from the open state, the finger inserted into the communication portion is relatively smoothly guided to the space by the guide surface portion. Furthermore, the fingertip guided by the guide surface portion does not hit a step, rib, or the like until it is guided to the space portion. Therefore, it is possible to make it easier to grasp the upper end of the door (put a finger on the outer surface side of the door) when closing the door which is in the open state.

Means 3. The container according to means 2, wherein the guide surface portion extends upward and inclined toward the inside of the container.

According to the means 3, the action and effect of guiding the finger inserted into the communicating portion to the space portion between the handle facing portion and the door portion are further exhibited. In addition, the depth from the outer surface of the side wall main body (bottom wall forming portion) in the portion facing the handle can be efficiently provided, and for example, a relatively large level difference more than necessary is formed at the lower edge portion of the portion facing the handle. As a result, it is possible to prevent situations such as another member being caught in the step or the step portion being damaged.

Means 4. The side wall main body of the side wall section with a door includes a side wall base wall section forming an inner surface of the side wall main body, and a side wall reinforcing rib projecting outward from the outer surface of the side wall base wall section,

Means 5. The container according to means 4, wherein a gap is also formed between the vertical rib adjacent to the upper side of the guide surface portion and the door portion in the open state.

According to means 4 and 5 , a gap is formed between the vertical rib adjacent to the upper part of the guide surface and the door in the open state. Therefore, even if the finger inserted into the space portion is further inserted above the guide surface portion, it is possible to prevent a situation in which the finger tip hits the vertical rib vertically. In addition, the formation range of the guide surface portion in the vertical direction can be shortened as much as possible, and complication of the configurations of the bottom wall forming portion and the side wall main body can be suppressed. In addition, if the finger inserted into the space is inserted above the guide surface, the feel of the fingertip will change (the guide surface will disappear).

A handle facing portion 34 is provided. Further, the handle facing portion 34 includes a communicating portion 35 that communicates between the space portion 33 and the space below the opened door portion 16 when the door portion 16 is opened. there is For this reason, when the door portion 16 in the open state is closed, the opening is formed between the outer surface of the door portion 16 and the handle facing portion 34 via the communicating portion 35 of the handle facing portion 34. By inserting a finger into the space part 33 and putting the finger on the outer surface of the door part 16, the peripheral part of the upper side part of the door part 16 arranged on the lower side of the door part 16 can be firmly grasped. In other words, when the door part 16 in the open state is lifted to the closed state side, the operation of placing a finger on the outer surface of the door part 16 can be performed relatively smoothly without imposing a burden on the finger. Furthermore, since the door portion 16 in the open state can be suitably grasped from the start of the work to close the door portion 16 in the open state, when the door portion 16 in the open state is to be lifted, the door is opened. A situation in which a hand slips from the portion 16 can be prevented.

Further, when opening the door portion 16 from the closed state, by placing a finger in the space portion 33, the door portion 16 can be brought into contact with or close to the outer surface of the side wall main body 14. , the finger can be put on the outer surface side of the door part 16. - 特許庁For this reason, a finger may be caught between the opened door portion 16 and the handle facing portion 34, or when the door portion 16 is opened, the outer surface of the door portion 16 and the side wall main body 14 may be pinched. Defects caused by removing the hand from the door portion 16 at a stage where the outer surface is relatively separated (damage to the door portion 16, the outer wall portion 31, and the hinge member 21 that supports the door portion 16, the door It is possible to prevent a situation in which the part 16 rebounds and hits the operator.

Therefore, the door portion 16 can be opened and closed relatively smoothly and more safely, and workability can be improved. In particular, when the container 1 is relatively large and the door portion 16 is relatively heavy, such effects are more pronounced.

Further, the outer surface of the outer wall portion 31 constituting the handle facing portion 34 is continuous from a portion (communication portion 35) located below the upper side portion of the door portion 16 in the open state to a portion corresponding to the space portion 33. In addition, no step is formed in the lateral width direction of the long-side side wall portion 6 . Therefore, when the door portion 16 in the open state is closed, a finger inserted into the communication portion 35 is relatively smoothly guided to the space portion 33 by the outer surface of the outer wall portion 31 . Furthermore, the fingertips guided by the outer surface of the outer wall portion 31 do not hit a step, rib, or the like until they are guided to the space portion 33 . Therefore, when closing the door portion 16 from the open state, it is possible to make it easier to grasp the upper end portion of the door portion 16 (put a finger on the outer surface side of the door portion 16).

In addition, since the outer surface of the outer wall portion 31 is inclined upward and extends toward the inside of the container body 2, the effect of guiding the finger inserted into the communication portion 35 to the space portion 33 is enhanced. Played more. In addition, the depth from the outer surface of the side wall main body 14 (bottom wall forming portion 5) in the handle facing portion 34 can be efficiently provided. It is possible to prevent situations such as another member being caught in the step or the step portion being damaged due to the fact that the projecting length of the lower side reinforcing convex portion 36 is increased.

Further, a vertical rib 37 extending vertically is provided adjacent to the upper portion of the outer wall portion 31 , and the lower portion of the outer edge portion of the vertical rib 37 extends continuously with the outer surface of the outer wall portion 31 . Therefore, a gap is formed between the vertical rib 37 and the door portion 16 in the open state. Therefore, even if the finger inserted into the space 33 is further inserted above the outer wall portion 31 , it is possible to prevent the fingertip from hitting the vertical rib 37 up and down. In addition, the formation range of the outer wall portion 31 in the vertical direction can be shortened as much as possible, and complication of the configurations of the bottom wall forming portion 5 and the side wall main body 14 can be suppressed. In addition, when the finger inserted into the space 33 is inserted above the outer wall 31, the feeling of touching the fingertip changes (the outer wall 31 disappears). It is possible to prevent the fingertips from contacting the long-side reinforcing ribs 19 with vigor.

In addition, a notch portion 38 is provided at the upper end portion of the outer surface of the door portion 16, and when the door portion 16 is in the open state, the portion of the door portion 16 provided with the notch portion 38 faces the handle. 34 (the outer surface of the outer wall portion 31) are arranged to face each other. Therefore, the space 33 formed between the handle facing portion 34 and the upper side portion of the opened door portion 16 can be expanded to the door portion 16 side. Furthermore, the entrance of the finger to the space portion 33 including the communication portion 35 can be widened. Therefore, the space 33 can be more suitably and widely secured. It is possible to avoid a situation in which the shape of the periphery of the handle-facing portion 34 is greatly changed and the strength is lowered, etc., when an attempt is made to secure only the recessed shape of 34 .

In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other applications and modifications not exemplified below are naturally possible.

(a) In the above embodiment, the entire width of the outer wall portion 31 is configured as the handle facing portion 34 so as to correspond to the entire upper side portion of the opened door portion 16. However, for example, If the container is relatively small, a handle-facing portion is provided corresponding to the portion including the center in the width direction of the upper side of the door portion 16, or if the container is relatively large, the width direction of the door portion 16 is provided. It is good also as providing a handle facing part in two right-and-left places in . However, when the door portion 16 in the closed state is opened, the portion of the door portion 16 that is grasped without being conscious of it does not correspond to the handle facing portion 34, and the handle facing portion 34 does not correspond to the handle facing portion 34. In order to avoid a problem caused by opening the door part 16 with the feeling of gripping the corresponding part, the handle facing part is arranged so as to correspond to the entire upper side part of the opened door part 16. 34 is desirable.

Even if the handle facing portion 34 is not provided so as to correspond to the entire upper side portion of the opened door portion 16, the handle facing portion 34 can be formed in the door portion 16 as in the above-described embodiment. When the cutout portion 38 is provided corresponding to the range, the cutout portion 38 serves as a mark of the formation range of the handle facing portion 34, and when the door portion 16 is opened, the upper side portion of the door portion 16 is opened. It is possible to prevent the above-mentioned inconvenience such as grabbing a portion that does not correspond to the handle facing portion 34 . Moreover, the cutout portion 38 of the door portion 16 may be provided at a position facing the handle facing portion 34 when the door portion 16 is opened. The notch portion 38 may be provided so as to match the formation range of the handle facing portion 34 in the direction. In addition, it is also possible to omit the notch 38 .

(b) In the above embodiment, the width of the space portion 33 in the thickness direction of the long-side side wall portion 6 is not particularly limited. The effect of making it easier to put your fingertips on is exhibited more remarkably. Moreover, it is desirable that the width of the space 33 is not as narrow as possible compared to the thickness of the operator's finger, and more preferably wider than the operator's finger.

In addition, the outer surface and the inner surface of the side wall body 14 may extend in a direction close to perpendicular (vertical direction) to the bottom wall portion 9. For example, the outer surface of the side wall body 14 faces upward. When the container main body 2 tilts inward, the door portion 16 in the open state is maintained in an outwardly open posture and the door portion interferes with the work, or the inside of the container main body 2 is molded. For example, when the outer surface of the side wall main body 14 tilts upward toward the outer side of the container main body 2, the door portion 16 in the open state flaps, or the hinge portion 21 is broken. In order to avoid problems such as increased burden, the outer surface and inner surface of the side wall main body 14 extend perpendicularly or substantially perpendicularly (vertical direction or substantially vertical direction) to the bottom wall portion 9. It is desirable to

Further, in the above-described embodiment, the substantially flat outer wall portion 31 is inclined upward toward the inner side of the container body 2.
