Description

  The present invention relates to a packaging container, and more particularly to a packaging container that is filled with frozen food and stored in a packaging bag.

  Conventionally, foods such as side dishes and side dishes are often put in a paper case or a film case and used as they are in a lunch box. In this case, the food is generally put in a case in a frozen state and sold in a packaging bag in a state where about 4 to 6 foods are put in a plastic tray or the like.

  However, when trying to sell food that has been heat-treated in a case, heating with the tray is not possible due to the material of the tray. Therefore, since it is necessary to transfer to a tray after heating for each case, it takes time.

  Further, after eating the food filled in such a case, it is necessary to separate and discard the case and the tray.

  Therefore, a container as shown in Patent Document 1 has been proposed.

  FIG. 8 is a perspective view showing the external shape of such a conventional packaging container, and FIG. 9 is an enlarged cross-sectional view of the IX-IX line shown in FIG.

  With reference to these drawings, a plurality of engagement holes 66 are formed on the upper surface of a paper connecting plate 65. The molding cup 61 attached to each of the engagement holes 66 is a paper bottled container opened at the top, and its upper end is folded outward to form a folded portion 63. Engagement grooves 64 are formed around the entire periphery.

  When the molding cup 61 is attached to the connecting plate 65, the engaging groove 64 of the forming cup 61 is engaged with the engaging hole 66 of the connecting plate 65 as shown in FIG. 9. As a result, the molding cup 61 is attached to the connecting plate 65 in a stable state.

  By configuring the packaging container in this way, it is possible to heat the food filled in the molding cup 61 together with the connecting plate 65. Further, since the forming cup 61 and the connecting plate 65 are both made of the same material mainly composed of paper, it is not necessary to separate and discard them.

In addition, the container like patent document 2 is also proposed as the same structure.

A cut line 20 c is formed between the recess 18 c and the opening 19. A cut line 20 d is formed between the recess 18 d and the opening 19. Then, four sections are formed by each of the cut line 20a to the cut line 20d, and each section constitutes the packaging frame body 17a to the packaging frame body 17d. As shown in the drawing, each of the packaging frame 17a to the packaging frame 17d has substantially the same square shape except that the positions of the recess 18 and the opening 19 are different.

  FIG. 2 is an enlarged plan view of a portion of the packaging frame 17a shown in FIG.

  As described above, the packaging frame 17a is formed of a substantially square sheet. First, a position on the inner side of the lower right corner is set as a starting point 24a, and a substantially L-shaped cut 25a extending from the position along the side 23a and the cut line 20b is formed. The length of the portion connected to the end point 26a is set shorter than the length of the portion connected to the start point 24a of the cut 25a, and the end portion on the end point 26a side is formed in an arc shape. A triangular notch 27a is formed at the corner of the cut 25a.

  Similarly, a cut 25b having the same shape as the cut 25a is formed along the cut line 20b and the cut line 20a, starting from the position on the inner side from the lower left corner of the packaging frame 17a. Similarly, a cut 25c is formed from the start point 24c along the cut line 20a and the side 23b. Further, similarly, a cut 25d is formed from the start point 24d along the side 23b and the side 23a.

  And the part between the cut | interruption 25a and the edge | side 23a comprises the frame part 30a. Similarly, a portion between the cut line 25b and the cut line 20b constitutes a frame portion 30b, and a portion between the cut line 25c and the cut line 20a constitutes a frame portion 30c, between the cut line 25d and the side 23b. The portion constitutes a frame portion 30d.

  Further, a portion between the cut 25a and the cut 25d constitutes a leg portion 31a connected to the frame portion 30d. Similarly, a portion between the cut 25b and the cut 25a constitutes a leg portion 31b connected to the frame portion 30a, and a portion between the cut 25c and the cut 25b constitutes a leg portion 31c connected to the frame portion 30b.
