Description

The present invention relates to a packaging sheet and a packaging box.
More specifically, the present invention relates to an article that can be safely accommodated even in an article in which a fragile article such as a bag is packaged by preventing vibrations and shocks from being directly transmitted to the article by transportation or the like.
In addition, the present invention relates to a device that has excellent air permeability without hindering accommodation of articles.

For example, a packaging box as described in Patent Document 1 (see FIG. 7) has been conventionally known as a package suitable for packaging plastic bags containing bags (hereinafter, abbreviated as “bag packs”). .
Japanese Utility Model Publication No. 58-16494

  Normally, this type of packaging box can be assembled by folding a packaging box component sheet made up of a single cardboard box along the crease, and the basket packs are arranged vertically and horizontally in a rectangular flat box. A total of four can be accommodated. In addition, the upper surface is wide open so that wrinkles can be seen from the outside at the time of store sales.

  Further, in order to allow ventilation even when the packaging boxes are stacked, the side wall is usually provided with ventilation holes and notches (see the notch 91 shown in FIG. 7). As a result, even if the packaging boxes are stacked when stored in the refrigerator before shipment, cold air flows into the packaging box from the vent holes or notches.

However, the conventional packaging box as shown in FIG. 7 has the following problems.
That is, the conventional packaging box has a structure in which the bag pack is simply placed on the bottom plate and accommodated. Therefore, since the bag is constantly in contact with the bottom plate of the packaging box with the plastic pack in between, vibration and impact are easily transmitted directly to the bag due to transportation and the like, and as a result, the bag is easily damaged.

  In addition, since the shipping of bags is usually carried out in a state where a large number of packaging boxes are stacked, it is inevitably subject to vibrations and shocks from the bottom side when stacking and transporting packaging boxes. It was fragile.

  Further, as described above, the side walls are usually provided with ventilation holes and notches so that ventilation can be performed even when the packaging boxes are stacked. However, the cooling efficiency when the packaging boxes are stacked and stored in the refrigerator is low only with the small holes and notches provided in the side wall, and the cooling cost is increased accordingly. Therefore, although it is conceivable to open a hole or a notch in the side wall, it is difficult because of physical strength for stacking the packaging boxes.

  Therefore, it is conceivable to make a hole or a notch in the bottom plate with a large opening. However, due to the structure in which the kite pack is placed on the bottom plate, a portion that cannot support the kite pack is generated, which is also difficult. It was.

Furthermore, as shown in FIG. 4, the frame plate engaging insertion pieces 5, 5 are bent at substantially right angles at the folds e, e, and the frame plate engaging insertion pieces 5, 5 are bent into the frame plates 31, 31. And are inserted into the receiving portions 311 and 311 for insertion pieces provided in the above. Thereby, the side wall 200 of the triple structure composed of the article support pieces 8A and 8B, the inner left and right side wall plates 4 and the folded pieces 6 and 6 is formed on the other two sides (left and right short sides) of the bottom plate 1 facing each other. .

(5) Put a finger into the finger-holding holes 93, 93 shown in FIG. 3, and as shown in FIG. 4, the pair of raised and raised article support pieces 9, 9 are bent and folded at the folds k, k. Insertion pieces 91 and 91 for engaging side wall plates at both ends are inserted and fixed to receiving portions 71 and 71 for cut and raised articles provided on the inner front and rear side wall plates 7. Opening 400, 400 (one opening 400 is hidden and cannot be seen) is formed at the bottom of the packaging box by cutting and raising the article support pieces 9, 9.

(6) As shown in FIG. 4, the engaging portions 101, 101 of the partition pieces 10A, 10B that have been separated in advance are fitted together and combined in a cross shape. Then, as shown in FIG. 5, the engaging portions 102, 102 of the partition piece 8B are cut up and fitted into the partition piece receiving portions 92, 92 of the article support pieces 9, 9, so that the partition is formed at the substantially central portion of the packaging box. The body 300 is constructed and the assembly of the packaging box is completed. In addition, the top part of the partition 300 (partition piece 10A) is designed to be essentially the same height as the side walls 100 and 200.

FIG. 6 is an explanatory side view showing a cross section of a part of the packaging box containing the bag pack and showing the internal structure.
The bag pack P is accommodated in the packaging box as follows.
That is, as shown in FIG. 6, the upper and lower ends of the article support piece 9 and the article support pieces 8 </ b> A and 8 </ b> B (the article support piece 8 </ b> B does not appear in FIG. 6) The edges 501 and 501 are hooked from above. In this way, the bag pack P is raised and supported by the article support piece 9 and the article support pieces 8A and 8B in cooperation with each other. Accommodate.

  Since the heights of the cut and raised article support pieces 9 and 9 and the article support pieces 8A and 8B are higher than the height of the bag pack P, the cut and raised article support pieces 9 and the article support pieces 8A The bag pack P can be supported in a state where the bottom portion 500 of P is floated from the bottom inner surface 112 of the packaging box. Therefore, the bottom portion 500 of the bag pack P does not contact the bottom inner surface 112 of the packaging box, and vibrations and shocks due to transportation and the like are not easily transmitted directly from the bottom portion of the packaging box to the bag pack P. Therefore, it is possible to prevent the wrinkles from being damaged quickly by vibration or impact.

  As described above, the opening portions 400 and 400 are formed at the bottom of the packaging box by raising and raising the article support pieces 9 and 9. Because the openings 400 and 400 ensure air permeability between the packaging boxes when the packaging boxes are stacked, the cooling efficiency when the packaging boxes are stacked and stored in the refrigerator is high. In addition, unlike the conventional packaging box that is placed directly on the bottom plate and accommodated, in this embodiment, the bag pack P is supported with the bottom 500 floating, so that an opening is formed at the bottom of the packaging box. Even if 400 is formed, there is no hindrance in accommodation of articles.

  Since the partition body 300 capable of partitioning the bag pack P is provided at substantially the center of the packaging box, it is possible to prevent the bag pack P from contacting each other during transportation and the like from being damaged.

  In the present embodiment, the top of the partition 300 is designed to be essentially the same height as the side walls 100 and 200. Therefore, when the packaging boxes are stacked, the bottom of the upper packaging box stacked by the partition 300 can be supported, so that the lower bag pack can be prevented from being crushed by the upper packaging box.

  If the article to be accommodated is not damaged even if it is subjected to vibration or shock, the article is cut up and the article supporting pieces 9 and 9 are not raised. It can also be placed directly on the bottom plate 1 and accommodated.
