  FIG. 1 is an overall perspective view showing a schematic shape of a packaging container according to a first embodiment of the present invention, and FIG. 2 is an enlarged end view taken along line II-II shown in FIG.

  Referring to these drawings, the packaging container 11 has a structure in which inverted frustoconical paper containers 31a to 31f are detachably attached to a box-shaped base 13 that is open at two opposite sides. .

  The pedestal 13 folds a piece of rectangular sheet-like cardboard into a right angle in parallel with one of the sides of the cardboard so that the shape of the open portion is rectangular, and the opposing sides parallel to the crease are It is the structure which adhere | attached so that it might join. The pedestal 13 includes a rectangular sheet-shaped first support plate 26, a rectangular sheet-shaped third support plate 28 connected perpendicularly to one side of the first support plate 26, and a first support plate 28. A rectangular sheet-like second support plate 27 connected perpendicularly to the third support plate 28 via a side opposite to the connection side with the support plate 26, and the third support plate 28 of the second support plate 27. A rectangular sheet-like fourth support plate 29 connected perpendicularly to the second support plate 27 via a side facing the connection side. An elongated rectangular sheet-shaped adhesive portion 19 is vertically connected to a side of the fourth support plate 29 that faces the side to be connected to the second support plate 27, and the first support plate 26 is connected to the third support plate 28. It is bonded along the side facing the connecting side. The first support plate 26 is formed with circular openings 18a to 18f having a size along the side wall 34 of the paper containers 31a to 31f.

  In this way, the base 13 can be easily created only by the procedure of bending and bonding a single rectangular cardboard.

  The pedestal 13 is placed so that the first support plate 26 faces upward, and each of the paper containers 31a to 31f has an opening in the first support plate 26 so that the bottom surface portion 33 contacts the second support plate 27. It is detachably attached via each of 18a-18f. At this time, the paper containers 31 a to 31 f are in a state where the side walls 34 a to 34 f are supported by the edges of the openings 18 a to 18 f in the first support plate 26. That is, the paper container 31 is stably supported in a state in which only the edge of the opening 18 of the first support plate 26 and the second support plate 27 of the base 13 is in contact.

  Further, the first support plate 26 in the base 13 is formed with cut lines 14a to 14c so as to divide each of the openings 18a to 18f, and the second support plate 27 and the first support plate 26 are also formed. Cut lines 21a to 21c are similarly formed at locations facing the formed ones. Further, among the cut lines 14 formed on the first support plate 26, the cut lines 14 b formed so that the end portions thereof become a connection portion with the third support plate 28 and a connection portion with the fourth support plate 29, and 14 c and the cut lines 21 b and 21 c (not shown) formed on the second support plate 27 opposite to the second support plate 27 are connected to the third support plate 28 with cut lines 22 a and 22 b. Cutout lines 23 a and 23 b (not shown) are formed on the 4 support plate 29.

  Of the cut lines 14a to 14c formed in this way, the portion that divides any of the openings 18, the corresponding cut lines 21a to 21c of the second support plate 27, and the cut lines 22a or 22b of the third support plate 28, Or if it cuts off by the cut line 23a or 23b of the 4th support plate 29, the paper container 31 attached to this opening 18 will be isolate | separated with the corresponding part of the base 13. FIG.

  Furthermore, a fixed length of cut is formed in the second support plate 27 and the fourth support plate 29 starting from two points of the connecting portion of the base 13 between the second support plate 27 and the fourth support plate 29. The portion sandwiched between the cuts is folded inside the pedestal 13 to form a first reinforcing piece 16a and a second reinforcing piece 17a. Similarly, the first reinforcing piece 16b and the second reinforcing piece 17b are also formed at the connecting portion between the second support plate 27 and the third support plate 28.

  FIG. 3 is an enlarged cross-sectional view taken along line III-III shown in FIG.

  Referring to the figure, the first reinforcing piece 16a and the second reinforcing piece 17a are bent inward so as to span the second support plate 27 and the fourth support plate 29, and the second support plate 27 And a bending angle in a direction opposite to the angle formed by the fourth support plate 29 is formed.

    FIG. 4 is a view showing a portion corresponding to FIG. 3, and the first reinforcing piece 16 and the second reinforcing piece 17 described above are formed when a lateral force is applied to the pedestal 13 from the outside. This is to compare what is not formed.

  As described above, in the paper container 31, the bottom surface portion 33 abuts on the second support plate 27 in the base 13, and the side wall portion 34 is supported by the edge of the opening 18 of the first support plate 26. That is, the first support plate 26 and the second support plate 27 are stably held in a state where the first support plate 26 and the second support plate 27 are spaced apart from each other, whereby stable support of the paper container 31 by the pedestal 13 is realized. That is, if these intervals are narrowed for some reason, the support of the paper container 31 becomes unstable.

  Based on this, the case where a lateral force is applied to the packaging container 11 from the outside will be described.

  The packaging container 11 shown in FIG. 4A is one in which the first reinforcing piece 16 and the second reinforcing piece 17 described in FIG. 3 are not formed. In this figure, when the force indicated by the arrow A is applied to the pedestal 13 in the packaging container 11, the cross section of the pedestal 13 is deformed from a rectangular shape to a parallelogram shape as shown in the figure. That is, as the distance between the first support plate 26 and the second support plate 27 shown in C in the figure is reduced, the position of the side wall portion 34 of the paper container 31 supported by the edge of the opening 18 of the base 13 is changed. The position is close to the bottom surface portion 33. For this reason, the stability of the support of the paper container 31 is reduced.

  On the other hand, in the packaging container 11 shown in (b), the first reinforcing piece 16 a and the second reinforcing piece 17 a are formed on the pedestal 13. When the force indicated by the arrow A is applied to the pedestal 13 in the same manner as shown in (a), the pedestal 13 tends to deform into a parallelogram in the same manner, but in this case, the first reinforcing piece 16a. And the 2nd reinforcement piece 17a becomes resistance, and the force shown by the arrow B in a figure generate | occur | produces in the direction opposite to A. FIG. For this reason, even when a force A equal to that shown in (a) is applied, the amount of deformation of the pedestal 13 is smaller than that in (a), so that the first support plate 26 and the first 2 The narrowing of the distance C from the support plate 27 is reduced. As a result, a packaging container in which the stability of the support of the paper container 31 by the pedestal 13 is hardly impaired is realized.

  FIG. 5 shows a state in which the packaging container 11 shown in FIG. 1 is actually used and is stored in a packaging bag, and one of the paper containers 31 together with the corresponding part of the base 13 is a packaging container. FIG.

  Referring to the figure, each of paper containers 31a to 31f is filled with cooked and processed foods 45a to 45f and is detachably accommodated in openings 18a to 18f of first support plate 26 in pedestal 13, respectively. The packaging bag 41 has a shape that completely accommodates the packaging container 11 and does not generate an extra space so as to cover and cover the paper containers 31a to 31f. For this reason, even when a force is applied from the outside (particularly below) during transportation or the like, the risk of the paper container 31 coming off the base 13 and falling down is minimized, and a more stable packaging is realized.

  When the cooked and processed food 45 is processed in a microwave oven or the like, the packaging container 11 is taken out from the packaging bag 41, and the cut line 14, the cut line 21, the cut line 22, and the cut line 23 on the pedestal 13 are processed by the number to be processed. The processing may be performed after separating and separating the corresponding parts. In the figure, the cooked and processed food 45f filled in the paper container 31f is separated together with the corresponding portion of the base 13.

  As described above, when the paper container 31 is attached to the base 13, the paper container 31 is in contact with only the second support plate 27 and the edge of the opening 18 of the first support plate 26. Since it is the same after individual separation at the time of processing, the state in which the paper container 31 is in contact with only the base 13 does not change even when performing heat treatment or the like in a microwave oven. When the processing is completed and the container is moved to another container such as a lunch box, the paper container 31 may be removed from the base 13 to be in a compact state. Therefore, for the first time, the paper container 31 is as shown in the illustrated paper container 31f. Is removed from the base 13. Up to this point, there is little possibility that the bottom surface of the paper container 31 will come into contact with the mounting surface of the microwave oven, and dirt and germs will adhere, so that a sanitary state can be maintained for a long time.

  Further, after use, both the paper container 13 and the pedestal 13 are made of paper material, so that separation at the time of disposal becomes easy and recycling becomes possible.

  In the first embodiment, a plurality of openings are provided in the pedestal, and a paper container is attached to each of the pedestals. However, it is sufficient that there are one or more openings in the pedestal and paper containers attached thereto.

  Moreover, in the said 1st Embodiment, although the opening formed in the base is circular shape, as long as it is a shape which can hold | maintain a food container, other shapes, such as a polygon, may be sufficient.

  Further, in the first embodiment, the food container has an inverted frustoconical shape, but other shapes such as a rectangular column shape can be used as long as the food container can be accommodated and is held by the opening in the pedestal. It may be.

  Furthermore, in the first embodiment, the pedestal is a box that is opened in two opposite directions. However, if the two flat plates are supported in an opposed state, there is no open portion. Alternatively, another configuration such as a support rod attached between two flat plates may be used.

  Furthermore, in the first embodiment, the reinforcing portion is formed on the pedestal, but other reinforcing methods may be used, or the reinforcing portion may not be formed.

  Furthermore, in the first embodiment, a cardboard is used for the pedestal and a paper container is used for the food container. However, other materials such as a resin sheet may be used.

  Furthermore, in the first embodiment, the cut line is formed on the pedestal, but the cut line may not be formed.

  Further, in the first embodiment, the pedestal and the paper container accommodated in the pedestal are accommodated in the packaging bag. However, the packaging bag may be omitted, or a film packaging is used instead of the packaging bag. But it ’s okay.
