  In the case of the conventional paper box shown in FIG. 3, in the shape in which the insertion piece formed by cutting the zipper is inserted into the insertion slit and resealed, the insertion piece is only inserted into the insertion slit, so that the object to be stored is on the lid. The lid pushes the lid by the repulsive force of the lid support plate, and the insertion piece comes out of the insertion slit and the lid easily opens.As a result, the object to be stored comes out of the box and functions as a lid. There is a drawback that it will not. Moreover, since it is necessary to form an insertion piece and a slit for insertion on the cover plate and to overlap and lock the cover plate, there is a disadvantage that the width of the cover plate becomes longer and the amount of paper used increases, leading to an increase in cost. .

  On the other hand, the conventional paper box shown in FIG. 5 can reduce the amount of paper used and reduce the cost by shortening the width of the cover plate, but has the disadvantage that it cannot be resealed as shown in FIG.

  Therefore, in the zipper-attached paper box, the width of the lid plate is shortened to reduce the amount of paper used, and the lids that are separated are reliably engaged when the lid is opened after opening by zipper cutting. A paper box with a reseal function that can be stopped is provided.

  The paper box with a reseal function of the present invention has a pair of cover plates each provided with a cutting line for forming a zipper on the upper side of the box, facing each other, and in a direction orthogonal to the direction in which the cover plates face each other. In a zipper-attached paper box in which a pair of lid support plates are arranged opposite to each other, the lid support plate can hold the lid plate from above when the lid is opened after opening the box, and the lid plate can be removed by cutting the zipper. A locking piece that can be locked by being hooked on the edge of the groove formed by the cutting line and that can be pulled out from the groove is provided in a row.

  In the above configuration, the box is formed by connecting the first side plate, the front plate, the second side plate, the rear plate, the bottom plate, the lid plate and the lid support plate, and the lid plate is on the upper side of the front plate and the rear plate. The lid support plate can be configured to be connected to the upper sides of the first side plate and the second side plate, respectively.

  Since the paper box with the resealable function of the present invention is locked so that the locking piece is caught by the edge of the cutting line of the cover plate pressed by the cover support plate and does not easily come off, the cover can be easily opened. Absent.

  Moreover, when opening a cover board, the both ends of a locking piece can remove | deviate from the edge of a cutting | disconnection line by pulling up a locking piece, and a latching can be cancelled | released easily.
