  However, in a conventional container having a manual feed hole, a finger inserted into the manual feed hole comes into contact with the load in the container and damages the load (for example, food) with the finger. A situation that could hurt a finger with mechanical parts) could occur. On the other hand, in the conventional container provided with the folding wall, there has been a problem that the handle portion protrudes greatly from the outer surface of the side wall and becomes an obstacle.

  The present invention has been made in view of the above circumstances, and can prevent a finger hung on the handle portion from coming into contact with the load and suppress the amount of protrusion of the handle portion from the outer surface of the side wall as compared with the conventional art. The purpose is to provide containers that can be used.

In order to achieve the above object, the container according to the invention of claim 1 has a side wall rotatably connected to each outer edge portion of a rectangular bottom wall, and the side wall is locked in an assembled state standing up from the bottom wall. In addition, the container can be changed to a folded state in which the lock is released by the operation of the operation member provided on the outer surface of the side wall and the side wall is stacked on the bottom wall, and the container is disposed below the operation member on the outer surface of the side wall. In a container having a handle portion where a finger can be hung from below , a side wall through hole formed on the side wall and a lower edge of the side wall through hole are hinged to connect the side wall through hole from the inside of the container. A rotating lid biased to a closing position for closing, and the handle portion includes an upper protruding wall protruding from an upper edge portion of the side wall through hole of the outer surface of the side wall, and a side wall through hole extending from the tip of the upper protruding wall to an intermediate position in the vertical direction of It is composed of a folding Kaekabe having a possible receiving space receiving a finger between the pivot lid of pendent and closed position under the folding Kaekabe is contained within the ribs projecting from the outer surface of the side wall, turned-back The distance from the inner surface of the wall to the rotating lid at the closed position is 5 to 22 [mm], and the distance from the lower surface of the folded wall to the upper side of the side wall through hole is 5 to 25 [mm]. The distance from the lower surface of the side wall to the lower side of the side wall through hole is characterized in that it is 10 to 25 [mm] .

The invention according to claim 2 is the container according to claim 1, further comprising a lower edge protrusion protruding from the lower edge of the side wall through hole in the outer surface of the side wall, and the inner surface of the folded wall from the front end surface of the lower edge protrusion. The distance between the upper and lower sides is 3 to 12 [mm], and the vertical distance from the lower surface of the folded wall to the upper surface of the lower edge ridge is 10 to 25 [mm] .

In the container according to the first aspect, the handle portion has a structure in which the folded wall is suspended from the tip of the upper protruding wall provided on the outer surface of the side wall. Accordingly, the container can be lifted in a state where the finger is bent in a hook shape and is hidden inside the folding wall. Here, if the upper protruding wall of the handle portion is simply protruded from the side wall and the folding wall is suspended from the tip, the folding amount of the holding portion from the outer surface of the side wall is reduced. You will not be able to hide your hand inside the wall. On the other hand, in the present invention, a side wall through hole is formed in the side wall and a rotating lid is hingedly connected to the lower edge portion thereof, and the upper protruding wall of the handle portion is projected from the upper edge portion of the side wall through hole. Since the folding wall is hung from the tip of the lever, even if the amount of protrusion of the handle from the outer surface of the side wall is suppressed, the finger can be hidden inside the folding wall while expanding the rotating lid with the back of the finger. it can. Moreover, since the finger hidden inside the folding wall is covered with the rotating lid from the inside of the container, it does not come into contact with the load. That is, according to the container of the present invention, it is possible to prevent the finger hung on the handle part from coming into contact with the load and to suppress the protrusion amount of the handle part from the outer surface of the side wall as compared with the conventional case.

In the container of claim 2 , the lower edge portion of the side wall through hole is reinforced by the lower edge protrusion. Also, when the hook is hidden inside the folding wall instead of the finger, the lower edge ridge contacts the position away from the tip of the hook, and the tip of the hook is the inner surface of the folding wall with the lower edge ridge serving as a fulcrum. It can be locked to press.
