Description

  The present invention relates to a carton with a lid used for storing confectionery, food, etc., and more particularly, to a carton with a lid having an engagement mechanism.

Conventionally, a carton with a lid and a carton having a reseal function have various forms. For example, as a typical form, like the carton P with a lid shown in FIG. 5, the free engagement piece 30 is connected to the front plate 12 of the carton body 1, and the free engagement piece 30 is the outer surface of the front plate 12. There is a configuration in which the lid front plate 22 of the lid body 2 is locked by the free engagement piece 30 when bent to the side and covered with the lid body 2 (see, for example, Patent Document 1).
Japanese Utility Model Publication No. 62-62625

  However, in the carton having the above-mentioned conventional resealing function, the free engagement piece is bent on the outside of the front plate, and a gap is formed between the carton body and the lid at the time of opening, and it is not properly resealed. There is a problem. Furthermore, it was difficult to apply to a flat carton having a low height. In addition, this loose engagement piece needs to be folded back to the surface side of the front plate in the box making process and the filling and packaging process, which is a difficult processing process. Furthermore, in order to make the engagement accurate, it is necessary to provide a loose engagement piece at the center of the front plate, which deteriorates the appearance and makes it easier to take out the contents when widening the opening. I was in trouble.

  The present invention is a carton with a lid in which the carton body and the lid are connected in a shape that covers the carton body, and can be easily opened, and the lid can be properly locked to the carton body when resealed, It is an object of the present invention to provide a carton with a lid that can be applied to a flat carton.

  In order to solve the above problems, the present invention includes a bottomed rectangular tube-shaped carton body including a front plate, a rear plate, both side plates, and a bottom plate, and a lid body including a top plate, both lid side plates, and a lid front plate. In the carton with a lid in which the top plate of the lid is continuously provided on the upper side of the rear plate so that the lid can be fitted to the upper outer side of the carton main body. On the upper side, a free engagement piece having side edges as engaging portions is continuously provided, and locking adhesive pieces provided continuously on the side sides of the lid side plates of the lid are respectively provided on the back surface of the lid front plate. A locking gap is provided between the top plate and bonded, and when the lid is fitted to the carton body, the free engagement piece and the locking adhesive piece can be engaged with each other. A carton with a lid.

  According to the present invention, in the carton with a lid in which the carton body and the lid are connected so as to cover the carton body, the free engagement piece is provided on the upper side of the side plate of the carton body. Bending inward and providing a locking gap on the upper side of the locking adhesive piece bonded to the back of the lid front plate, the free engaging piece is locked and bonded when the lid is fitted to the carton body. The carton body and the lid can be locked by engaging with the upper edge of the piece. That is, it is easy to open, and the lid can be properly locked to the carton body at the time of resealing, and a carton with a lid that can be applied to a flat carton can be obtained. Further, the appearance is not impaired as compared with the shape in which the loose engagement piece is provided on the front plate. Furthermore, when taking out the contents, it is possible to make the contents easy to take out by providing a notch or the like in the front plate to widen the opening, and the contents are held by the loose engagement pieces when the lid is opened. You can also have the effect of doing.
