Description

  The present invention relates to a fruit and vegetable packaging box for packing and transporting fruits and vegetables such as cherry tomatoes in bulk.

  Conventionally, when packing cherry tomatoes into a packaging box for transportation, they are sent while being dropped continuously by a machine. The packaging box is provided with a partition plate for reinforcement during stacking.

  By the way, when a cherry tomato falls in a packaging box, it may collide with the upper end of a partition plate. Since the cut surface of the corrugated cardboard is exposed at the upper end of the conventional partition plate, the sharp shape may damage the cherry tomatoes. In addition, since the cut surface of the cardboard is easily deformed, the strength of the packaging box may be lowered because the partition plate cannot withstand depending on the load at the time of stacking. Furthermore, since the conventional partition plate is generally bent in an L shape, the tomatoes may fall down when they are packed unevenly.

Utility Model Registration No. 3038383

  The first problem to be solved by the present invention is to prevent the fruits and vegetables fed by the machine at the time of filling up from being damaged even if they collide with the upper end of the partition plate. The second problem is to prevent the partition plate from being deformed or toppled even with respect to a large load applied when packaging boxes are stacked or a packing condition in which fruits and vegetables are biased.

The configuration of the present invention that solves this problem is as follows.
1) In cardboard fruit and vegetable packaging boxes for packing and transporting fruits and vegetables in bulk, open the insertion holes on the opposite side plates of the packaging box with the top open, and reinforce the opposing insertion holes. The fruit and vegetables are characterized by having a double structure in which both ends of the partition plate are inserted and attached to the same height as the side plate, and the partition plate is bent in a U-shaped cross section to form a flat upper end surface. Packing box partition structure 2) The side plate has a double structure in which corrugated cardboard is folded into a U-shaped cross-section, and insertion holes are formed in a V shape on the inner side plate of the double-structure side plate. The partition structure for fruits and vegetables packaging box according to 1), wherein a V-shaped notch is formed at an end, and the notch is fitted into the insertion hole from above to attach a partition plate.
It is in.

  According to the configuration described in 1) of the present invention, the corners of the folds of the partition plate are formed by rounding the corrugated cardboard. Can preserve the quality of fruits and vegetables. Moreover, even if the packaging boxes packed with fruits and vegetables are stacked and loaded, since the support is supported by the flat upper end surface of the partition plate, the partition plate is hardly deformed and the strength of the packaging box can be maintained. Furthermore, since the both ends of the partition plate are inserted into the insertion holes, even if the fed fruits and vegetables are unevenly packed, they do not fall down.

  According to the configuration described in 2) of the present invention, as the load is applied from above, the insertion hole of the inner plate and the notch of the partition plate are closely intimately engaged with each other, and the strength of the packaging box and the partition plate is further improved. To do.

It is an expanded view of the packaging box of an Example. It is an expanded view of the partition plate of an Example. It is explanatory drawing which shows attachment of the partition plate of an Example. It is a perspective view of the packaging box of an Example. It is explanatory drawing which shows the cross section of the partition plate of an Example, and its attachment state.

  Hereinafter, the form for implementing this invention is concretely demonstrated based on an Example and drawing.

  FIG. 1 is a development view of the packaging box of the embodiment, FIG. 2 is a development view of the partition plate of the embodiment, FIG. 3 is an explanatory view showing attachment of the partition plate of the embodiment, and FIG. 4 is a perspective view of the packaging box of the embodiment. FIG. 5 is an explanatory view showing a cross section of the partition plate of the embodiment and its attached state.

  In the figure, 10 is a packaging box, 11 is a bottom plate, 12 is an outer plate, 13 is an inner plate, 13a is an insertion hole, 14 is an upper end plate, 14a is an insertion hole, 15 is a side plate, 16 is a cover plate, 16a is Insertion pieces, 17 and 18 are folding plates, 20 is a partition plate, 21 is a side plate, 22 is an upper end plate, and 23 is a notch.

  The packaging box 10 of this embodiment is made of double-sided corrugated cardboard, and as shown in FIG. Pieces 17 and 18 are formed. A V-shaped insertion hole 13 a communicating with the upper end plate 14 is opened at the center of the inner side plate 13, and elongated insertion holes 14 a are opened on the left and right sides of the upper end plate 14. Side plates 15 and a cover plate 16 are provided on the left and right sides of the bottom plate 11, and insertion pieces 16 a for insertion into the insertion holes 14 a are formed at both ends of the cover plate 16.

  The partition plate 20 is made of double-sided corrugated cardboard, and as shown in FIG. The V-shaped notch 23 is formed. In FIGS. 1 and 2, a broken line indicates a fold line.

  In this embodiment, the outer plate 12 and the side plate 15 are folded up with the bottom plate 11 as the bottom, the inner plate 13 is folded inward, the folding plates 17 and 18 are folded inward, and the covering plate 16 is folded into the folding plate 17 and the upper end plate 14. The insertion piece 16a is folded down and inserted into the insertion hole 14a. Further, the side plate 21 is folded with the upper end plate 22 of the partition plate 20 as a flat surface, and as shown in FIG. 3, the notch 23 is fitted and attached to the insertion hole 13a from above, and the packaging box shown in FIG. 10 is assembled.

  As shown in FIG. 5, the partition plate 20 has a U-shaped cross section by the upper end plate 22, and the corners of the folds are rounded by corrugated cardboard. Thereby, even if the cherry tomato sent in with the machine collides with the upper end of the partition plate 20, it becomes difficult to be damaged, and the quality of cherry tomato can be maintained. Further, even if the packaging boxes 10 packed with cherry tomatoes are stacked and loaded, they are supported by the flat upper end plate 22 of the partition plate 20, so that the partition plate 20 is hardly deformed and Strength can be maintained. Furthermore, since both ends of the partition plate 20 are inserted into the insertion holes 13a, the fed tomatoes will not fall down even if they are unevenly packed.

  In particular, since the V-shaped insertion hole 13a of the inner plate 13 and the V-shaped notch 23 of the partition plate 20 are fitted together, the packing box 10 The strength of the partition plate 20 is further improved.

  The technology of the present invention is used for packing vegetables or fruits whose surface is easily damaged, such as cherry tomatoes.
