Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a packaging device in which a plurality of cardboard packaging boxes containing items to be packaged, such as televisions and microwave ovens, are stacked one on top of the other to form one unit.

Conventionally, this type of packaging equipment stacks multiple packaging boxes made of cardboard boxes specified in the JIS format that contain the items to be packaged, and then lays a composite material such as a wooden pallet at the bottom of the pile. However, these were tied together by wrapping them vertically using cable ties.

However, since the cable ties are applied in the vertical direction, the length of use becomes long, and since the required binding force cannot be obtained, the bands may become loose due to vibration and impact during transportation, which can cause damage to the base material, packaging box, or Packaging boxes may move relative to each other, causing the cargo to collapse, and the side walls of individual packaging boxes that are piled up due to movement may not be aligned vertically, resulting in an unstable load condition, which may cause balance problems. This has disadvantages such as loss of packaging and deformation of the packaging box.

The present invention was developed to eliminate the above-mentioned drawbacks, and involves providing engaging pieces on both ends of the bottom of the packaging box so that they come into contact with the base material or the packaging box on the lower side when stacked, and also with a band in the lateral direction. It is an object of the present invention to provide a packaging device that can form a unit package by tightening and maintain a stable loaded state without causing problems such as deformation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, details of the present invention will be explained with reference to the drawings for one embodiment.

Reference numeral 1 indicates a unit packaging body, which includes a plurality of packaging boxes 2 formed into a rectangular parallelepiped, and base materials 3, 3 that support these packaging boxes 2.
and a fastening band 5 that wraps and fixes the stacked packaging boxes 2, 2 from the circumferential side via retaining pieces 4 formed on both ends of the bottom surface of the packaging boxes.

As shown in FIG. 2, the packaging box 2 includes a trunk frame 6 made of corrugated paper, for example, which is newly formed in the shape of a rectangular tube, and this trunk frame 6.
a lid body 9 consisting of a pair of inner flaps 7.7 bendably connected to the periphery of the upper opening surface 13 and a pair of outer flaps 8, 8 similarly connected in a direction perpendicular to the flaps 7; The inner flaps 11,1 and the outer flaps 12,12 are bently connected to the periphery of the opening surface 10 as described above, and the connecting portions of the outer flaps 12 are bent into two stages to form the engaging pieces 4,4. Bottom part 1 formed
4.

Further, to explain in detail the engaging piece 4, the other opening surface 1
If the side plate 15 is formed with an appropriate width dimension a from the connecting position with 0, and is further bent into a U-shape from this side plate 15 via the bending line 15a, the width dimension a that abuts the inner flap 11 A side plate 16 is formed, and an outer flap 12 is formed from this side plate 16 via a fold line 16a.

Therefore, the retaining piece 4 is made up of side plates 15 and 16 that are bent and erected through the fold line 15a.

The base material 3 is formed from a pair of wooden pieces having a substantially rectangular cross section.

Next, the assembly and packaging procedures will be described.

To form the packaging box 2, first the inner flaps 11.11 forming the bottom part 14 are folded in, and then the outer flaps 12 are folded in.
．． 12 fold lines 15a and 16a are bent to form a pair of retaining pieces 4, 4, and the remaining flaps 12 are folded in and each tip is attached with, for example, adhesive tape 17 to form the bottom part 14. .

Next, the predetermined lower cushioning material 1 is inserted inward from the upper opening surface 13.
8. After accommodating the packaged object 19 and the upper cushioning material 18', the inner flap 7 and the outer flap 8. The lid body 9 is formed by folding the ends and pasting each tip with an adhesive tape 17.

And packaging boxes 2, 2, formed in this way...
In this case, a pair of base materials 3, 3 are brought into contact with the position where the bottom 14 of the packaging box 2 located at the lowest level and the engaging piece 4 intersect at right angles, and the outer retaining piece The base material 3 is fixed by the retaining member 20 from the 4 side.

Then, the packaging boxes 2, 2... are stacked one on top of the other, and the engaging pieces 4, 4 formed at both ends of the bottom of the upper packaging box are brought into contact with the upper side surface of the lower packaging box 2. The unit package 1 is completed by winding and fixing the upper part with a fastening band 5.

In addition, as the retaining member 20, a nail 20' is used as shown in FIG.
If this is used, there is a risk that the nail head may become embedded because the retaining piece 4 is made of cardboard.

Therefore, a preventive device such as a special washer 21 is required.

However, in the present case, as shown in FIG.
A plurality of stitch wires 22 are disposed intermittently in a double-shape with a predetermined interval α at appropriate positions on the outer side wall of the
Since the washer 21 is attached, the washer 21 can be made unnecessary by driving the engaging member 20 into the middle part of the wire 22 arranged in a two-shape as shown in FIGS. 6 and 7.

Further, the folded portion of the wire 22 strongly contacts the base material 3, and the side walls of the retaining piece 4 are brought into close contact with each other, further improving the engagement strength.

Further, when the stacked packaging boxes 2 are tightened by the fastening band 5, the wire 22 can increase the coefficient of sliding friction and prevent the band 5 from loosening.

FIG. 8 shows another embodiment of the shape of the engagement piece 4, and the engagement piece 4' may be provided with a protrusion 23 formed by bending.

As described in detail above, the present invention stacks a plurality of packaging boxes each containing an object to be packaged and having engaging pieces at both ends of the bottom surface, and the engaging pieces of the packaging box located at the bottom are stacked on top of each other. This is a packaging device in which a unit packaging body is constructed by engaging the composite material, and having the retaining piece of the upper packaging box contact the upper edge of the lower packaging box and fixing the circumferential side with a fastening band. The side walls of the stacked individual packaging boxes are positioned on a vertical line, so that a stable loaded state can be maintained.

In addition, even if vibrations or shocks occur during transportation, they are not directly transmitted to the band, and the length of the band used is short, so that sufficient binding force of the band can be obtained.

Furthermore, the workability is also improved, and there is no movement between the composite material and the packaging box, or between the packaging boxes, and the cargo collapses during transportation.

In addition, it has the special advantage of not causing deformation, reducing the amount of packaging material, and making it possible to reduce costs.
