Is formed by bending a band-shaped relatively thick synthetic resin plate through the fold lines 2 and 2 to connect the wide front plate 3 and the rear plate 4 with the narrow bottom plate 5 connecting them together. A cover main body is formed by extending a lid portion 9 which is folded into a plurality of portions via folding lines 6, 7, 8 on the upper edge of the rear plate 4, and the left and right side edges of the front plate 3 and the rear plate 4 Narrow, vertically long left and right sleeves 11, 11, each of which is folded inward through a fold line 10, are integrally provided. The upper edge of the lid 9 is folded back to cover
A reinforcing plate 12b which is superposed on the inner surface of the front plate 3 is continuously provided, and one end of a locking means 13 for holding the lid 9 closed with the upper part of the front surface of the front plate 3 is provided at the superposed portion. A piece 14b is attached, and the other stop piece 14a is connected to the upper edge of the front plate 3 and is provided with a kerf on both sides to leave ear pieces 15, 15, so that the front plate 3 is cut off. It is attached to the overlapping portion of the reinforcing plate 12a bent inside and the front plate 3.

Reference numerals 16 and 16 depict a fan-shaped relatively thin synthetic resin plate in a bellows shape, and are bent outward at the front and rear edges through a valley fold line 17 to form an inner surface of the sleeve pieces 11 and 11. This shows a pair of left and right side walls that are integrally provided by extending a welding margin 18 that is superposed and welded. The front panel 3 and the rear panel 4 are moved forward and backward by welding the welding margin 18 and the sleeve 11. Connected by direction. The left and right side edge plates 19a are formed of a relatively thin synthetic resin plate having a horizontal rectangular shape.
A partition plate which is welded to the inside of each of the opposed valley folds 6 and 16 to partition between the front plate 3 and the rear plate 4 to form a plurality of storage portions 20 is shown. A heading 21 is provided at the upper edge of the partition plate 19.
