Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a self-supporting carton.

[0002]

2. Description of the Related Art Conventionally, flat cartons have a poor self-sustainability and lack display effects at stores and the like.
In order to make the flat carton self-supporting, another member is used as a screen, and various complicated cartons are devised.

[0003]

However, in the conventional carton, the use of another member is complicated, and the production process is not simple due to the complicated shape of the carton. There is a problem such as weakening the strength of the.

[0004] In addition to providing a display effect, it is necessary to provide a carton with autonomy in a carton for storing a pouch for a microwave oven. Fluid foods, such as cooked curry and soups, which are called retort foods, are usually filled in aluminum retort pouches, sealed, heat-sterilized, and stored in flat cartons for sale. When heating in a microwave oven, the pouch is taken out of the carton, the contents are transferred to another container, and then heated in a microwave oven in order to avoid rupture of the pouch due to expansion of the contents due to heating. Another easy transfer involves the problem that the heat-resistant pouch is not effectively used and the handling of the user is complicated. There is also a method of opening a ventilation hole in a part of the pouch, but it is difficult to make the pouch itself stand alone in a microwave oven, and there is a problem that there is a risk of leaking or falling down. It is necessary to make the carton self-supporting so that heating can be carried out in a microwave oven while storing the carton.

In view of these problems, the present invention can be manufactured by a general manufacturing process, and can easily become self-supporting with the contents stored therein without reducing the strength of the carton. It is intended to provide autonomous cartons.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides at least a rear panel, a side panel,
A flat carton formed by folding a blank consisting of a front panel, a side panel, and an extension panel so as to overlap the extension panel and the rear panel, wherein any of the overlapped extension panel and the rear panel is formed. A self-supporting carton, characterized in that a screen part is provided on the inner panel or a narrow drawer is provided on the outer panel, and the screen part can be pulled out from the drawer.

[0007] The screen part is substantially hexagonal having at least a quadrangular support part and triangular reinforcement parts connected to both sides of the support part, and the other side of the support part is the rear panel. And the drawer portion is substantially hexagonal in size and larger than the support portion and smaller than the partitioning portion.

Further, a perforation for opening or a zipper for opening is provided on an upper portion of the carton, and the perforation for opening or the zipper for opening is provided on a pouch which is a content to be stored in the carton. It is provided so as to face the formed opening notch.

According to the present invention, there is provided a self-supporting carton which can be manufactured by a general manufacturing process and which can easily have self-supporting property without reducing the strength of the carton while the contents are stored. Obtainable.
