Claims (4)

  A pair of wall portions opposed to each other with a space therebetween to form an accommodation space for accommodating the objects to be accommodated, and ends of the pair of wall portions to prevent the objects within the accommodation space from falling off. And the pair of wall portions and the closing portion are formed by bending a sheet material, and the closing portion is based on respective edges of the pair of wall portions. It is constructed with a pair of extending portions formed so as to be longer than the distance between the edges of the wall portion that is the base end of each extending portion, and is extended to the ends. The pair of extending portions are bent at the proximal ends so that the distal ends are connected to each other and the connecting portion is located between the pair of wall portions. The one extension portion is formed with the extension amount from the base end being substantially the same as the interval between the wall portions, and the other extension portion has the extension amount from the base end of one extension portion. The extension portion is formed approximately half of the extension amount, and one extension portion is bent at a substantially right angle with respect to one wall portion to become a substantially horizontal bottom, and the other extension portion is the other wall. 2. The case according to claim 1, wherein the case faces the other wall portion along the inner surface of the portion, and a connection site of the pair of extending portions is located on the other wall portion side .   The closing portion further includes an auxiliary closing portion that extends from an end edge of the one wall portion as a base end, and is continuously formed on both sides of the one extending portion. The shape is set so as to deform by following the bending of the extending portion by pushing the extending portion between the wall portions and close the space between the extending portion and the wall portion. The case described.   The closing portion further includes a covering portion that extends from the edge of the other wall portion as a base, and is continuously formed on both sides of the other extending portion, and the covering portion includes a pair of extending portions. 4. The shape is set so that the portion is pushed between the wall portions while following the bending of the other extension portion and folded between the wall portions so as to cover the auxiliary closing portion from the outside. The case described.
