Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that, when a closed lid of a corrugated box or the like is opened at the center of the lid, the lid has to be cut open toward both left and right, which takes a force for opening twice as strong as a force for opening in one direction to make the opening of the lid difficult, and a removed unsealing cutout forms an opening that allows a foreign matter, such as dust, to come into the box, which deteriorates the preservation condition of a content, such as a food, of the box when it is used again. <P>SOLUTION: A packaging box 10 is provided. When the packaging box 10 is closed, opening/closing edges 3a and 3b of the lids 9 and 12 are fixed on side panels 5 and 6 forming an opening, using a closure means 28. An unsealing cutout 28, which can be cut out along a cut line 29 consisting of a plurality of incisions, is formed at the corner end of the opening/closing edge 3a. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a packaging box.

  Conventionally, like a cardboard box, a pair of lids are connected to opposite sides of the opening of the container body, the lids abut each other, and the abutment is covered with tape or the like to close the lid. In such a packaging container, a packaging container is known in which an opening cut portion is provided at the center of the lid so that the pair of lids can be opened from the center after the contact portion is covered. (For example, refer to Patent Document 1).

Japanese Patent No. 3200040

  However, since the unsealing part that was originally provided as a part of the lid in the central part of the lid is difficult to unseal, it is necessary to close the notch so that it can be easily trimmed. In the conventional example, the thumb flap that can be easily pushed in to form the cut flap, the intermediate flap, and the final flap are divided into the open cut portion that is provided on the body. By providing, both the strength as a lid and the ease of opening are made compatible.

However, when opening in the center, the lid must be cut open toward both sides, so that the opening force is doubled, which is quite difficult. Also, when the opening cut-off part is removed, the removed part becomes an opening, and when the box is used again, foreign matter such as dust, sun, lighting, etc. from the opening opened to the lid to the inside of the box There was a problem that the storage condition of the contents such as foods was deteriorated, and it was difficult to reuse the box once used.
In addition, after removing the opening cut provided in the central part of the lid, there is a problem that labor is required for the opening work because the opening work is performed to open the lid in two directions from the central part of the lid to both ends. there were.

Accordingly, the present invention provides a packaging box in which the opening / closing edge of the lid is fixed to the box opening by the closing means in the closed state, as defined in claim 1. In this case, a packaging box is provided in which an open cut-out part that can be cut off by a cutting line made of a plurality of cuts is provided at the corner end of the box.
