Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to a packaging box that has a flap that closes the opening of the box body and is easily opened.

Conventional configuration and problems Conventionally, cartridge music tapes have been produced by storing a rolled tape on which music signals have been recorded in a cartridge case, inserting the cartridge case into a cosmetic case, and wrapping the outer periphery with cellophane. The cartridge is a completed music tape product. When this finished product is shipped to the market, for convenience, the finished product is packed in a packaging box in sets of 10, and then the packaging boxes 2 are further made into sets of 10 and packed in cardboard cases before being shipped to the market.

In the process of packaging the finished products in sets of 10 in this packaging box, conventionally the lid with the flap of the packaging box and the wall of the box body facing the flap were attached with adhesive tape. In this case, the tape sometimes peeled off, causing problems. Additionally, a tape pasting device was required, making management complicated.

There are also open-type packaging boxes in which the flap part is folded onto the inner surface of the box body without being attached with tape, but in this case, the adhesion between the flap part and the box body is weak, so the wrapping is done in the next process. The problem was that the box was easily damaged.

Therefore, some packaging boxes use glue to attach the flap part to the box body, but in this case, strong adhesion is maintained, but when opening the packaging box, it is difficult to open and the product inside the packaging box cannot be opened. It is difficult to take out the package, and if the package is opened, the packaging box will be damaged and cannot be reused.

In addition, Utility Model Publication No. 1983-45123 and Utility Model Publication No. 56-
As shown in Japanese Patent No. 38986, there is also a case where a separation section defined by perforations or cuts is provided on the wall surface of the box body where the flap of the lid is joined, and this separation section is used as an adhesive section.

According to this structure, since the flap is adhered to the wall surface, the opening of the box body is temporarily sealed, and when the box is opened, the detachable portion can be cut off from the wall surface, making it possible to reuse the box.

However, if the area of the cut-off portion is made small, the sealing of the box body will be incomplete, and if the area of the cut-off portion is made large, the strength of the box body after opening will be weakened, which will hinder reuse.

Purpose of the invention This invention solves the above-mentioned disadvantages. It is possible to maintain sufficient adhesion between the flap part and the box body, and it is easy to open, and even when opened, the strength of the box body is improved. To provide a packaging box that can withstand reuse without significantly decreasing its properties.

Structure of the invention The present invention provides a packaging box in which a flap of a lid that closes an opening of a box body is joined to a wall part of the box body that faces the flap, and the flap and wall part constituting the joint part are connected to each other. A separation section defined by a perforation or a cut is provided on one side, and a separation section is provided on the other side at a position sandwiching the separation section, and these separation sections are used as an adhesive section.

According to the present invention, in the packaged state, the flap is adhered to the wall surface of the box body at three locations, so that the opening of the box body is almost completely sealed. In addition, when opening the package, after cutting off the center part, insert your fingertip into the hole formed there and apply force to separate the joints on both sides. remains in the joint and can be easily opened. In this way, there are three separate parts that make up the adhesive part, and they are distributed between the flap and the wall, so even if the area of each separate part is small, the box body can be sufficiently sealed, and it can be reused even after opening. It can maintain the strength to withstand.
