Therefore, the entire multi-stage packaging container 10 can be folded into a sheet shape. Therefore, a large number of multi-stage packaging containers 10 can be stacked in a folded state, and can be stored and transported without being bulky.

Next, the procedure for using the multi-stage packaging container 10 of the present embodiment will be described with reference to FIGS. 6 to 8.

First, a multi-stage packaging container 10 folded into a sheet shape is prepared, and the first accommodating portion 1 and the second accommodating portion 2 are erected, and as shown in FIG. 6, inside the holding hole 4 of the first accommodating portion 1. By inserting a vertically placed food container F1 such as a beverage cup with a lid from above, the food container F1 is held by the holding hole 4. By inserting the food container F1, the standing state of the first storage portion 1 and the second storage portion 2 can be maintained. Then, with the first storage portion 1 and the second storage portion 2 standing upright, a flat food container F2 such as a food box with a window is placed in the first storage portion 1 from the rear opening 15R side. By inserting the other flat food container F3 into the second storage portion 2 from the rear opening 25R side, the food container is inserted into the first storage portion 1 and the second storage portion 2, respectively. F2 and F3 are accommodated.

Next, as shown in FIG. 7, the food stored in the first container 1 by reverse-folding the first reverse folded piece 52 of the retaining portion 5 of the first container 1 inward of the rear opening 15R. A food container housed in the second storage part 2 by preventing the container F2 from falling off and by reverse-folding the second reverse folding piece 54 of the retaining part 5 of the second storage part 2 inward of the rear opening 25R. Prevent F3 from falling out.

If necessary, a food and drink tool G1 such as a straw can be inserted and fixed in the holding cut 43 of the first top plate portion 13 of the first accommodating portion 1, and the second ceiling of the second accommodating portion 2 can be fixed. A food and drink tool G2 such as a spoon can be inserted and fixed in the holding cut 26 of the plate portion 23.

Then, as shown in FIG. 8, the pair of left and right wing pieces 3 and 3 are raised upward, and the bent piece 34 of one wing piece 3 is passed through the opening of the other wing piece 3 to the left and right. By grouping the handles 32 together, a plurality of food containers (F1, F2, F3) can be housed in the first storage section 1 and the second storage section 2, and can be stably carried by hand. If necessary, ornaments such as ribbons may be attached by using the cut 35 of each wing piece 3.

As described above, according to the multi-stage packaging container 10 of the present embodiment, the flat food containers (F2, F3) are housed in the first storage part 1 and the second storage part 2 formed in two upper and lower stages, respectively. Further, the lower first accommodating portion 1 can be projected forward from the upper second accommodating portion 2, and the vertical food container F1 can be held by the holding hole 4 provided in the protruding portion. Therefore, not only vertical food containers such as paper cups but also a plurality of flat food containers such as lunch boxes can be stably and compactly held and transported at the same time.

Moreover, the food container F1 held by the holding hole 4 provided in the protruding portion of the first storage portion 1 causes the food containers (F2, F3) housed in the first storage portion 1 and the second storage portion 2, respectively, to move forward. It is possible to prevent the food containers (F2, F3) from falling out, and the retaining parts 5 provided in the rear openings of the first storage part 1 and the second storage part 2 prevent the food containers (F2, F3) from falling out backward. Can be done. Therefore, it is not necessary to seal the front and rear openings of the first accommodating portion 1 and the second accommodating portion 2 with, for example, a plurality of flaps, and it is possible to provide a packaging container having a simple structure and low cost. (1) The food container can be easily inserted / removed from the storage unit 1 and the second storage unit 2.

Further, according to the multi-stage packaging container 10 of the present embodiment, the retaining portion 5 is formed in the rear openings of the first accommodating portion 1 and the second accommodating portion 2, respectively. Since it is composed of the reverse folded piece 54, the food container can be pulled out and released with one touch, and the handleability can be further improved.

Although the multi-stage packaging container 10 of the present embodiment has been described above, the present invention can also be implemented in other embodiments.

For example, as in the multi-stage packaging container 20 shown in FIGS. 9 and 10, a retaining portion 6 for preventing the food container from falling off is provided on the rear end edge of the bottom plate portion 11 with a tongue piece 61 via a fold line. It may be composed of the insertion cut 62 provided in the second top plate portion 23 and into which the tip end side of the tongue piece 61 can be inserted. According to the multi-stage packaging container 20, it is possible to prevent the food containers (F2, F3) housed in the first storage part 1 and the second storage part 2 from falling off at the same time.

Further, in the above embodiment, the first accommodating portion 1 and the second accommodating portion 2 are formed in two upper and lower stages, but the present invention is not limited to this, and for example, the first accommodating portion 1 and / Alternatively, by providing a shelf board portion in the second accommodating portion 2 or further providing another tubular accommodating portion on the second accommodating portion 2 in the upper stage, the food container can be accommodated in a multi-stage manner. May be good.

Further, in the above embodiment, the holding hole 4 provided in the protruding portion of the first storage portion 1 holds a beverage container such as a lidded beverage cup as an example of the vertically placed food container F1. , A food container having an opening at the top and accommodating a plurality of stick-shaped foods upright, or a flat-standing food container may be held in the holding hole 4. If various food containers inserted into the holding holes 4 project upward and downward from the first top plate portion 13, the food containers housed in the first storage portion 1 and the second storage portion 2 are rearward, respectively. Can be prevented from falling out. The shape, size, and the like of the holding hole 4 can be appropriately redesigned according to the type, shape, size, and the like of the food container to be held.

Further, in the above embodiment, the opening width dimension of the front opening 15F and the rear opening 15R of the first accommodating portion 1 is set to the opening width dimension of the front opening 25F and the rear opening 25R of the second accommodating portion 2. The same, but for example, the opening width dimension of the first accommodating portion 1 may be larger than the opening width dimension of the second accommodating portion 2, or the opening width dimension of the second accommodating portion 2 may be the opening of the first accommodating portion 1. It may be larger than the width dimension. Various design changes can be made according to the type, shape, size, etc. of the food container to be stored in the first storage unit 1 and the second storage unit 2.

The present invention can be carried out in a mode in which various improvements, modifications, and modifications are added based on the knowledge of those skilled in the art, without departing from the spirit of the present invention. Further, any of the invention-specific items may be replaced with another technique within the range in which the same action or effect occurs, or the invention-specific items integrally configured may be composed of a plurality of members. Alternatively, the invention-specific items composed of a plurality of members may be implemented in a form integrally configured.
