Description

  The present invention relates to a pack storage interior material used when a strawberry pack or the like is packed and transported.

  In general, when transporting a strawberry pack, as shown in FIG. 5, cross-shaped partitions 52, 53 that engage with kerfs are set inside a tray-shaped box 51, and formed by the partitions 52, 53. The pack P is stored in each section.

  The box body 51 is maintained by embedding the folding pieces 57 extending from the pair of side walls 55 among the side walls 55, 56 provided continuously around the bottom wall 54 with the other pair of side walls 56 having a double structure. Shaped.

  However, in the packaging as described above, since the pack P is directly placed on the bottom wall 54 of the box 51, the impact during transportation acts on the strawberries of the pack P without being reduced, and the strawberries are easily damaged. there were.

  Then, this invention makes it a subject to provide the interior material for pack storage which can prevent the damage of the strawberry at the time of transport.

  In order to solve the above-described problems, in the present invention, in a cardboard interior material installed in a box for storing a pack, a middle frame portion that defines a storage space for the pack, and a leg portion that is bent downward from the middle frame portion In addition, a fitting portion along the side surface of the pack is connected in series, and the flange of the pack inserted into the storage space is lifted to support the pack in a suspended state.

  If the pack is supported in a suspended state in this way, a gap is created between the bottom wall of the box and the bottom surface of the pack, and the horizontal movement of the pack is also suppressed at the abutment portion, so the impact during transportation is reduced. This prevents the strawberries in the pack from being damaged.

  In addition, if the rounding which spreads toward the base end is provided in the side edge of the said abutting part, the abutting part will repel and will be pressed against the side surface of a pack, and the horizontal movement of a pack will be prevented reliably.

  Moreover, if the support piece bent in the V shape is inserted in the center part of the said middle frame part, the bending of the bottom wall of the box at the time of stacking will be suppressed, and a strawberry will be protected.

  Furthermore, if a protrusion is provided on the leading edge of the abutting portion and this protrusion engages with a locking hole formed in the bottom wall of the box, positioning is facilitated when setting the box, The interior material is stable with respect to the box, and the pack can be easily inserted into the pack storage section partitioned by the middle frame section.

  As described above, when the interior material according to the present invention is set in a box and the pack is supported in a suspended state, a gap is formed between the bottom wall of the box and the bottom of the pack, Since the horizontal movement of the pack is also suppressed, the impact during transportation is mitigated, and the strawberry packed in the pack is prevented from being damaged.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  The packaging container illustrated here is made of corrugated cardboard used for transporting a strawberry pack, and is composed of a blank of a box 1 and an interior material 2 as shown in FIG. A support piece 3 with a ruled line in the center is attached to the interior material 2.

  In the blank of the box 1, a pair of side walls 12 and an end wall 13 are provided continuously around the bottom wall 11, and an inner plate 14 is provided continuously at the leading edge of the side wall 12. Folding pieces 15 and 16 are connected to both side edges of the side wall 12 and the inner side plate 14, and a crosspiece 17 is connected to the front end edge of the end wall 13. Insert pieces 18 are provided at both ends of the crosspiece 17, and insertion holes 19 are provided at the boundary between the side wall 12 and the inner plate 14. Near the center of the bottom wall 11, four locking holes 11a are formed.

  In the blank of the interior material 2, the leg portions 22 are connected to both ends of the cross-shaped middle frame portion 21, and the abutting portion 23 is connected to the opposing edge of the leg portion 22 and the middle frame portion 21. The inner edge of the abutting portion 23 is provided with a roundness extending toward the base end, and a V-shaped insertion hole 24 is provided in the central portion of the middle frame portion. A protrusion 23 a is provided at the tip edge of the abutting portion 23 connected to the middle frame portion 21.

  To assemble the blank of the box 1, as shown in FIG. 2, the side wall 12 is erected from the bottom wall 11, the inner plate 14 is overlaid on the inner side, and the folding pieces 15 and 16 are folded inward. The wall 13 is erected, the crosspiece 17 is bent horizontally so as to overlap the top of the side wall 12, and the insertion piece 18 is inserted into the insertion hole 19.

  In order to set the interior material 2 in the box 1, the leg portion 22 is bent downward from the middle frame portion 21, the abutting portion 23 is also bent downward, and the outer surface of the leg portion 22 follows the inner surface of the inner plate 14. As described above, the leg portion 22 is placed on the bottom wall 11, the protrusion 23 a is engaged with the locking hole 11 a, the support piece 3 is bent into a V shape along the central ruled line, and inserted into the insertion hole 24.

  In this state, the abutment portion 23 of the interior material 2 is repelled by the roundness of the base side edge and protrudes to the inside of each pack storage portion defined by the middle frame portion 21 to be engaged with the protrusion 23a. By the engagement of the holes 11a, the interior material 2 is positioned and stabilized with respect to the box body 1. Further, the support piece 3 is prevented from coming off from the insertion hole 24 by repulsion of the central fold.

  As shown in FIGS. 3 and 4, when four strawberry packs P are inserted into each pack storage part of the box 1, the flanges of the pack P are three-way with the middle frame part 21 and the leg part 22 extending vertically and horizontally. The pack P is supported in a suspended state.

  At this time, since the protrusion 23a is engaged with the locking hole 11a and the repulsion is suppressed, the pack portion 23 can be inserted easily. Since the swing is possible due to the margin of the hole 11a, an excessive pressing force does not act on the strawberries packed so as to inflate the side wall of the pack P.

  When the pack P is stored in this way, a gap is formed between the bottom wall 11 of the box 1 and the bottom surface of the pack P, and the abutting portion 23 of the interior material 2 is pressed against the side surface of the pack P to pack P Since the horizontal movement is also suppressed, the impact during transportation is mitigated, and the strawberry packed in the pack P is prevented from being crushed and being rotted from the crushed portion.

  Further, when the boxes 1 are stacked, the bending of the upper-side bottom wall 11 is suppressed by the lower-side support piece 3, so that the strawberry that rises from the pack P is also prevented from being crushed.

  By the way, in the said embodiment, although the leg part 22 and the attachment part 23 of the interior material 2 are bend | folded along a ruled line, the blank of the interior material 2 is press-molded, and the leg part 22 and the attachment part 23 are shown. The bent state may be maintained.
