Description

  The present invention relates to a packaging box that is particularly suitable for storing and transporting mainly fruits and vegetables such as vegetables and fruits, and relates to a packaging box that can be partially opened and resealed.

  Conventionally, corrugated cardboard boxes of 0201 type (formerly A-1 type) of JIS-Z1507, which have been produced in a factory and delivered in an assembled state, are often used for packaging boxes that are boxed and shipped. This 0201 type box has a rectangular parallelepiped shape in which rectangular four-side plates are connected in one direction, and the bottom and top surfaces of the box are sealed above and below the four-side plates. Box.

  However, for the box-sealing work of the above type, since it is necessary to prepare an adhesive tape, a sealing metal fitting and a driving machine (stapler) thereof, the cost of the auxiliary material for sealing is required. When handling a large amount of relatively heavy contents such as fruits and vegetables, it is common to use a stapler rather than an adhesive tape to seal and seal, but the contents in the box are damaged by the sealing bracket. There is a risk, and the metal fittings after use are incombustible and cannot be incinerated with cardboard, so it is necessary to separate them.

Corrugated cardboard boxes containing fruits and vegetables are required to be safe and easy to work at the time of opening and dismantling after use, and the generation of trash from secondary materials for sealing is avoided at mass retailers. . Furthermore, it is necessary to pay attention to the handling of the used box because it may be injured by the sealing metal fitting during the sorting work when reusing the used box as waste paper.
In addition, when sealing with secondary materials, use for applications where the sealed box must be opened and re-sealed after checking the contents is not only inferior in workability but also with secondary materials. It was practically difficult because the box was damaged by the adhesive tape and sealing metal fittings.

In order to avoid the above problems, various types of packaging boxes have been proposed as packaging boxes that do not require auxiliary materials such as sealing metal fittings and adhesive tape for sealing the top surface (Patent Documents 1 and 2). ). Such a packaging box is easy to open and re-seal, and is particularly suitable when the supplier needs to check the state of the contents frequently, such as fruits and vegetables. It is used.
In addition, when it is necessary to make it easier to check the contents, there is also a type of packaging box in which the contents can be seen even if each top flap is shortened and completely sealed (Patent Document 3).

In the case of the packaging box described in the prior art documents cited as Patent Documents 1 and 2, even if a part of the top flap is opened at the time of opening, the open part is small, so the range in which the state of the contents can be confirmed becomes narrow. If all the face flaps are opened, it takes time to re-seal, so there is a problem that workability is inferior.
In addition, as in Patent Document 3, the cardboard case of the type in which the contents can be seen from the opening on the top surface in a sealed state is easy to check the contents, but has a size that protrudes from the opening on the top surface. It is not suitable for use with shape-shaped contents or sensitive contents that require the entire top surface to be sealed and protected.
The present invention is easy to open and reseal after sealing, and it is easy to check the contents because a large opening can be obtained just by opening a single flap.
