Description

[0001]
[Industrial application fields]
The present invention relates to a packaging case in which a tray containing foods is packaged.
[0002]
[Prior art]
Conventionally, trays molded with aluminum foil, plastic sheets, resin-coated paper, etc. are often used as simple containers for selling foods, but aluminum foil trays with relatively high strength are Alzheimer's dementia. There is a theory that it becomes a cause, and there is a tendency that the tray is replaced with a tray of a material other than aluminum foil.
[0003]
However, trays molded from materials other than the aluminum foil have low strength and are easily deformed when sold, transported, heated by a microwave oven, etc., and the gripping portion is deformed when inserted and removed when heated by a microwave oven. In addition to being easy to do, there are problems such as difficulty in taking out with fingers due to heat during heating.
[0004]
In order to prevent deformation due to contact with other items when selling or transporting trays containing foods, means to store them in ordinary paper boxes are also used, but simply placing the bottom of the tray at the bottom of the box The paper box side plate is merely brought into contact with the outer end of the outward flange of the tray mouth portion, so that the tray is not sufficiently held when an impact is applied and the tray is likely to be deformed. Has no use other than tray storage.
[0005]
[Problems to be solved by the invention]
In view of the problems of the conventional tray and its packaging box, the present invention can hold a low-strength tray formed of a material other than aluminum foil without causing deformation during sales and transportation, and a microwave oven. Packaging with a built-in tray that can be easily inserted and removed with fingers without being affected by deformation or heat, and can be placed on a table with the tray set after heating. The challenge is to provide a case.
[0006]
[Means for Solving the Problems]
In order to solve the above problems, a packaging case having a tray according to the present invention includes a bottom plate having an even number of sides, sides facing each side of the bottom plate in the same phase, and multiple sides of the side of the bottom plate. The top plate has two edges at a plurality of positions of the side plate of the packaging case that are assembled to face each other on the side plate, and the two edges closely contact the back surface of the inner plate when the packaging case is assembled. Formed by a corner web selected in the above manner, and having a folded portion protruding inward of the case, and between the upper surface of the folded portion and the top plate, outward of the peripheral edge of the opening of the tray mounted in the packaging case A flange is inserted and placed (claim 1).
[0008]
Here, the packaging case in which the tray is built can be configured such that an easily breakable line surrounding portion having the same shape as the outer peripheral shape of the inner edge of the outward flange of the tray is formed on the bottom plate. Item 2).
[0009]
[Action]
