Japanese Patent No. 5567721

  In the container in which the exterior body is deformed, when the exterior body is deformed, there is a large difference between the shape of the flexible packaging bag and the shape of the exterior body to be deformed. For this reason, if the adhesion surface of the outer package and the soft packaging bag is limited to a specific part, the soft packaging bag will be wrinkled when the outer package is deformed, making it difficult to handle the contents of the inner packaging bag. Moreover, it is easy to cause a tear of an exterior body. In addition, the container has a constricted shape in which the middle abdomen is recessed inward with the outer body deformed so that it can stand on its own, especially when taking out the contents of the container with tableware or eating directly. The recessed middle abdomen gets in the way.

  Moreover, since the said container uses the soft packaging bag provided with the gusset in order to make it self-support, it is difficult to reduce cost and to maintain a flat shape in the state which accommodated the contents.

  The present invention has been made in view of the above circumstances, is easy to carry with reduced bulkiness, and can maintain a wrinkle-free shape in a flexible packaging bag even in an assembled state. It is an object of the present invention to provide an inexpensive container that can be easily handled and can be eaten comfortably and directly.

In order to achieve the above object, the container of the present invention comprises:
A flexible soft bag portion having flexibility and capable of accommodating contents;
It is formed in a hard sheet shape from the soft bag portion, and is provided with a hard sheet portion that can be deformed into a box shape having a bottom surface that is bent at a predetermined position by pressing from both sides and opened upward from a flat shape,
The hard sheet portion is provided integrally with the soft bag portion.

According to this structure, since it is made into the flat shape before a deformation | transformation of a hard sheet | seat part, it is not bulky and it is easy to carry. Moreover, by assembling the hard sheet portion, the hard sheet portion is easily deformed into a box shape having a bottom surface, so that it can function as a self-supporting food container. Specifically, by opening the upper portion of the soft bag portion, the contents of the container can be taken out or eaten directly using tableware while the container is self-supporting.
Here, since the hard sheet portion is provided integrally with the soft bag portion, the soft bag portion is expanded without wrinkles in a state where the hard sheet portion is assembled in a box shape. Therefore, the contents of the container can be easily handled in a state where the container is self-supporting and can be eaten comfortably.
Further, since a gusset for self-supporting is unnecessary, the cost can be reduced, and the flat shape can be easily maintained in a state where the contents are accommodated, and high portability can be obtained.

  In the container of the present invention, the soft bag portion is formed of a soft packaging bag formed of a flexible film, and the hard sheet portion is formed of a sheet material harder than the soft packaging bag. Thus, the outer packaging body may be adhered and adhered to the outer peripheral surface of the flexible packaging bag.

  According to this structure, the adhesion area of a flexible packaging bag and an exterior body can be enlarged by adhere | attaching the whole exterior body on the outer peripheral surface of a flexible packaging bag, and closely_contact | adhering it. As a result, it is possible to make the exterior body less likely to break, and the soft packaging bag can be well protected by the exterior body when carried in a bag or the like. In addition, since soft packaging bags and exterior bodies made of different materials can be used, functions such as airtightness and light shielding required for packaging materials that contain food are ensured by the flexible packaging bags, For example, the width of the design can be expanded by performing decorative processing such as die cutting or embossing.

  In the container of the present invention, the hard sheet portion deformed into a box shape may have a shape that gradually spreads upward from the bottom surface side.

  According to this configuration, since the hard sheet portion deformed into a box shape has a shape that gradually spreads upward from the bottom surface side, the contents of the container can be taken out to every corner using tableware, Furthermore, you can eat comfortably.

  According to the container of the present invention, it is easy to carry with reduced bulk, and even in an assembled state, the flexible packaging bag can maintain a wrinkle-free shape, and the contents can be handled easily. Also, it is possible to provide an inexpensive container that can be eaten comfortably and directly.
