  However, the above wrapping paper box has a breaking cut on the lid covering the opening of the box body, and there is a problem in resealability, or unintentional tearing occurs from the breaking cut when opened. May end up.

  Also, an extension piece of the lid piece. Before opening, in the case of a structure that is superposed on the front side wall of the box body, the superposition part of the top side of the box main body occupies the top of the front side wall of the box body, The design was limited.

  This invention has been made in view of the above circumstances, and not only has excellent sealing performance, but also does not cause unintentional tearing when opened, and can adversely affect the design of the front wall surface of the box body. The purpose is to provide a packaging paper box that can be made as small as possible.

  In order to achieve the above object, the present invention provides a plug piece for closing a top opening of a box body, which is connected from the upper edge of the rear wall of the box body, and is inserted into the inside of the box body at the tip of the lid piece. In the wrapping paper box in which the tabs are continuously arranged, the tabs are continuously provided at the tip of the insertion piece, and the top side of the insertion piece located on the left and right of the tab is attached to the outer surface of the front wall of the box body. The sticking piece is provided continuously through a breaking cut, and the breaking cut is mainly composed of a plurality of intermittent cuts having a rising angle of 5 to 20 degrees diagonally to the left and right of the knob portion at the center of the insertion piece, One end of the intermittent cut is provided with a first bent cut extending toward the outer side of the sticking portion, and the other end of the adjacent intermittent cut is extended in a direction opposite to the first bent fold. Packaging paper box provided with two bent cuts , The gist.

  The distance between the first bent cut and the second bent cut is preferably set to 0.5 to 1.5 mm. Although it depends on the paper thickness of the paper box, if it is too narrow, it will be easily opened when force is applied to manipulate the knob unintentionally, and if it is too wide, it will break the breaking cut when necessary. Because it becomes difficult.

  The length of the second bent cut is preferably set to be larger than the length of the first bent cut.

  The angle formed by the intermittent cut and the first bent cut and the second bent cut is preferably set to 135 degrees or more.

  In order to open this device, the insertion piece and the polymerization sticking piece must be separated, and after the separation, it cannot be returned to the original state, which can contribute to prevention of mischief.

  After opening, the insertion piece at the tip of the lid piece can be resealed by being inserted into the box body along the inner surface of the front wall of the box body, and the function of the lid piece is not impaired.

  Since the breaking cut is mainly composed of a plurality of intermittent cuts having a rising angle of 5 to 20 degrees diagonally to the left and right of the knob part in the center of the insertion piece, the area of the insertion piece and the polymerization sticking part is made as small as possible, Minimize restrictions on the design applied to the front wall surface of the box body.

  One end of the intermittent cut is provided with a first bent cut extending toward the outer side of the sticking part, while the other of the adjacent cuts is a second extended in the direction opposite to the first bent fold. Since the bent cut is provided, the breakage at the time of opening is performed smoothly.

  When the interval between the first bent cut and the second bent cut is set to 0.5 to 1.5 mm, the opening operation can be performed more smoothly.

  When the angle formed by the intermittent cut and the first bent cut and the second bent cut is set to 135 degrees or more, the opening operation can be performed more smoothly.
