Description

[0001]
BACKGROUND OF THE INVENTION
The present invention includes a bar-shaped light such as a backlight of a liquid crystal display such as a word processor, a personal computer, a ticket vending machine, a register, a bar-shaped heater such as a throwing heater for a tropical fish tank, a bar-shaped thermometer, a glass product, a ceramic dish, etc. The present invention relates to a packaging box used when shipping fragile items such as tableware, home appliances and precision equipment parts.
[0002]
[Prior art]
Electronic parts, precision equipment, glass products, home appliances, tableware, etc. are very delicate and may be damaged, dented, or damaged by a slight impact. In the case where the products are shipped together in a packaging box, in order to protect these products, they are generally placed in a holder, and a certain amount of this holder is packed in a box for transportation. At this time, in the corrugated cardboard box for storing the holder, a cushioning material was inserted between the product and the holder or the box so as to reduce the impact from the outside during distribution.
[0003]
For example, as shown in FIG. 10, when shipping a cold cathode tube (lamp) G used as a backlight of a liquid crystal display formed of a glass tube having an elongated pipe shape with a length of 300 mm, 500 mm or more, Since the lamp is long and light and easily damaged by a slight impact, the lamp G is arranged and fixed on the lamp holder 11 as shown in the figure, and then loaded and transported in a plurality of stages in the cardboard box 20. . The lamp holder 11 was composed of a holder mount 12 and a cushioning material 13 affixed thereon. As the holder mount 12, a detachable cardboard sheet formed according to the inner dimensions of the cardboard box 20 is used, and as the cushioning material 13, a sponge type urethane foam having excellent buffering properties against external impacts is used. It was.
[0004]
As shown in FIG. 10, the urethane foam cushioning material 13 has an elongated bar shape, and two of the urethane foam cushioning materials 13 are fixed substantially in the center of the holder mount 12 in parallel by hot melt bonding.
On the upper surface of the parallel urethane foam cushioning material, kerfs 14 provided at a predetermined pitch in the direction orthogonal to the respective length directions were formed. Each end of the lamp G, which is an easily damaged product, is attached so as to straddle the two cushioning materials by using each cut groove, and is elastically supported. The lamp holder 11 is stored in a plurality of stages in a corrugated cardboard box 20 and is transported in such a manner that the top and bottom pads 15 are set on the uppermost stage to stop the movement from side to side, front and rear, and up and down.
In this way, by using the elasticity of the urethane foam cushioning material bonded to the holder mount to a lamp that is fragile due to impact, the lamp holder is lined up and fixed to the lamp holder to mitigate external impact during shipping and distribution and prevent damage. It was.
[0005]
[Problems to be solved by the invention]
However, according to the conventional lamp packing and shipping method as described above, since the parts of the lamp holder are made of different materials, they are separated into urethane foam, which is a cushioning material, and cardboard sheets of holder mounts during collection and recycling. There was a need. This point will be explained in detail. When recycling a used holder as a raw material (material recycling), the urethane foam cushioning material is fixed integrally to the holder mount with an adhesive such as hot melt, so that both are separated by material. It was necessary to separate the fraction. However, since both of them are firmly bonded by an adhesive, it is not easy to separate them, which requires a lot of labor and cost. Further, in the case of thermal recycling (incineration treatment), there is a restriction that the ratio of the paper must be 50% or more by weight, and even when it is 50% or more, separation processing is preferable as much as possible. Therefore, in this case as well, there is a problem that the urethane foam and the corrugated cardboard are not suitable for thermal recycling treatment because they cannot be easily separated if they are hot-melt bonded.
[0006]
Furthermore, when the holder is returned and reused without being discarded after use, it is difficult to separate the urethane foam cushioning material and the holder mount because they are hot-melt bonded. Has the disadvantage of being expensive. Also, it is impossible or not easy to replace any damaged parts. If it is forcibly separated, the holder mount and / or the cushioning material itself may be unusably broken. In the conventional method, an adhesive and an adhesive device such as a hot melt gun are always required when the cardboard board and the cushioning material are fixed at the packaging work site. In addition, since the urethane foam cushioning material is easily deformed, it is necessary to take measures to prevent the cushioning material from shifting or deforming during use as well as during bonding work, and a little heavy material is placed on the urethane foam. There was a problem that the urethane foam was crushed easily.
[0007]
The present invention aims to solve the above-described conventional problems. In recent years, companies that ship products must take responsibility for collecting and recycling paper and plastic packaging containers that store products and buffer packaging materials for protecting and fixing products (re-commercialization). Both legally and legally.
Therefore, we propose a shock absorber mounting plate and packaging box using this that can pack easily damaged items such as bar lights, and can disassemble and separate different materials very easily when collecting and recycling used materials. Is. That is, the cushioning material mounting plate of the present invention can be recovered by adopting a means for fixing the cushioning material to the holder mount by an insertion method without using a complicated adhesive or a special adhesive device for bonding. Each part can be easily separated during recycling, and each part can be easily replaced and reused easily. In addition, each part can be easily handled during delivery, return and packaging. It can be saved.
Furthermore, the cushioning material mounting plate of the present invention eliminates the need for special processing such as providing a hole for positioning or holding the cushioning material itself at the bottom of the packaging box in order to place the cushioning material.
Furthermore, the present invention proposes a cushioning material mounting plate that can be prevented from being crushed or damaged by the weight from the top when the cushioning material mounting plates are stacked, and a packaging box using the same.
[0008]

The sheet 1 is formed in a size that can be fitted and removed according to the inner dimensions of the box so that it can be stacked and accommodated in a cardboard transport packaging box. The illustrated sheet 1 can be formed of either substantially rectangular or square paperboard or cardboard. However, it is preferable that the sheet 1 is made of cardboard because the impact can be alleviated. The urethane foam cushioning material 2 is a rectangular or square sheet 1 as described later, and standing pieces 3 (with both ends of the cushioning material locked) or 5 (center of the cushioning material) cut and raised from the sheet. It is attached parallel to the long side of the sheet by locking the area. In addition, corner cuts 1a are formed at the four corners of the sheet 1, and notches 1b and 1b for handling are formed at both ends of the center (see FIG. 3).
[0018]
Two sets of upright pieces 3 are formed so as to be foldable on both sides of the sheet so as to sandwich the longitudinal center line of the sheet 1. Each upright piece 3 is formed in a substantially U-shape, and is configured to be able to be cut and raised in the vertical direction from the sheet 1 through a fold line 3a as shown in FIG. Incidentally, reference numeral 4 denotes a locking hole formed between the upright piece and the sheet when the upright piece 3 is cut and raised from the sheet 1.
The urethane foam cushioning material 2 is inserted into the locking hole 4 (closed loop-shaped hole shape) of the upright piece 3 formed at both ends 2b of the sheet 1 from both sides, as shown in FIG. The cushioning material 2 is detachably attached.
[0019]
The upright piece 5 at the intermediate portion is formed so as to be foldable between the upright pieces 3 at the left and right ends so that it can be cut and raised in the vertical direction via a fold line 5a. Unlike the upright piece 3, the upright piece 5 has a pair of opposing hook-shaped (reverse L-shaped) locking portions 5 b that are divided into left and right sides. This hook-shaped locking portion forms a locking hole 6 whose upper portion is not closed when it is cut and raised from the sheet 1. The urethane foam cushioning material 2 is engaged with the engaging hole 6 through the middle portion of the urethane foam cushioning material 2, but since the upper part is open, it can be detached from the upper part.

After the urethane foam cushioning material 2 is inserted into each hole 4 or 6, the upright piece 3 is inserted into the kerf 2a. Alternatively, the upright piece 5 is engaged to prevent the cushioning material 2 from falling off the sheet 1. It should be noted that the cut groove 2a for supporting the backlight G and the holding groove for locking with the upright pieces 3 or 5 may have different structures.
[0021]
(Example 2)
FIG. 6 is a development view of the seat 1 used for the shock absorber mounting plate 10 used when the relatively heavy backlight G is arranged and fixed. The sheet 1 is formed of paperboard or cardboard having a substantially rectangular or square shape as in the first embodiment. The sheet 1 is formed with upright pieces 3 or 5 that are cut and raised from the sheet 1 in the same manner as in the first embodiment, except that a hole 7 is formed between the upright pieces 3 and 5 as described later. It is the point which formed and the convex part 8 was formed in the back surface of the shock absorbing material 2. FIG. Other than that, there is no difference from the first embodiment, and the assembling method of the upright pieces 3 and 5 is the same. Therefore, the same reference numerals are given to substantially the same members as those in the first embodiment.
7 and 8 are a side view and a plan view of the urethane foam cushioning material 2 of this embodiment. This buffer material has an elongated shape with a rectangular cross section, as in the first embodiment. On the upper surface of the cushioning material 2, kerfs 2a having a depth reaching the central portion of the cushioning material are formed at a predetermined pitch in a direction perpendicular to the length direction as in the first embodiment. A convex portion 8 is formed at a position corresponding to the hole 7.
[0022]
When the sheet 1 and the urethane foam cushioning material 2 are used in combination, the cushioning materials are arranged in parallel on the upper surface of the sheet 1 as shown in FIG. In that case, the convex part 8 which protrudes in the back surface side of this buffer material 2 is made to fit in the hole 7 which the said protrusion provided in the sheet | seat 1 fits. By fitting the convex portion 8 and the hole 7 in this way, the urethane foam cushioning material 2 is positioned and held, and it is prevented from being displaced or deformed by an external impact or vibration during distribution. The backlight G of the liquid crystal display held in 2a is prevented from shifting and directly hitting the packaging box and being damaged.
[0023]
(Other examples)
In the first and second embodiments, an example in which a urethane foam cushioning material is used is shown, but the present invention is not limited to this. When a sponge-like urethane foam cushioning material is used as in the above embodiment, excellent cushioning performance is exhibited as a cushioning material for the glass tube. It is optional to use a resin cushioning material, synthetic rubber or natural rubber cushioning material which is rich in cushioning properties other than the above, such as foamed polystyrene, foamed polyethylene, and polystyrene foam, and is lightweight and easy to mold.
Further, in this embodiment, two long and narrow cushioning materials are used as one set, like a rod, but the present invention is not limited to this, and a flat cushioning material can be used alone. The flat cushioning material is fixed by inserting both ends of the flat cushioning material into the locking holes of the upright pieces cut and raised from the sheet 1, or by integrally forming projections at both ends of the flat cushioning material. It can be attached by inserting into the locking hole.
In the above embodiment, the upright pieces 3 with the locking holes are provided at both ends of the sheet. However, a plurality of upright pieces with the locking holes can be provided between the upright pieces 3 and 3 so as to be cut up and raised. Furthermore, it is free to provide a plurality of hook-shaped standing pieces 5 between the standing pieces 3 and 3. Furthermore, the number of the protrusions 8 provided on the back surface side of the cushioning material and the holes 7 provided on the sheet side engaged therewith are also free.
[0024]
Further, in the embodiment, both ends of the backlight G of the liquid crystal display are inserted and held in the groove 2a for holding the commodity of the two cushioning materials 2 arranged side by side on the sheet. By changing the shape, it is possible to fit and hold easily damaged items such as throwing heaters for tropical fish tanks, tableware such as rod-shaped thermometers or dishes, home appliances and precision equipment parts. The number and shape of the kerfs are formed according to the product to be held, and are not limited to narrow slits as shown in the illustrated example, but may be formed in relatively wide grooves with large dents. is there.
[0025]
Next, an example in which the backlight G is fixed to the cushioning material mounting plate according to the present invention and stored in a packaging box for shipping will be described. As described above, the shock-absorbing material mounting plate is housed and shipped in a general-purpose cardboard box 20 generally called an A-type box in the industry. That is, as shown in FIG. 10, the cushioning material mounting plates in which a plurality of backlights G are arranged and fixed on the cardboard box 20 are stacked in a plurality of stages, and the top pad is set in the uppermost stage, thereby It is transported in such a way as to stop the movement up and down. At this time, the cushioning material mounting plate 10 of the present invention stacked in the box is an upright piece having the same height that is cut and raised from the sheet 1 so as to be almost the same height as the cushioning material 2 as shown in FIG. Since the upright piece supports the weight from the upper part because it is supported on 3 or 5, the cushioning material 2 is not crushed.
[0026]
【The invention's effect】
As described above, according to the present invention, when the cushioning material such as urethane foam is fixed on the cushioning material mounting plate during the packing operation, the cushioning is provided in the locking hole of the standing piece cut and raised on the mount. Since both end parts in the length direction of the material are inserted and attached, the mount and the cushioning material can be fixed with little effort and cost without using an adhesive or special equipment for bonding. Therefore, it is possible to reduce the cost and time of the packaging work, and to disassemble and separate different materials very easily when collecting and recycling each part after use.
[0027]
In addition, because the cushioning material is attached to the mount using the insertion method, the cushioning material and the mount can be transported and stored separately during delivery and return of packaging materials, increasing the storage and transport efficiency of the material, and storing and transporting costs. Can be reduced. Further, when returned and reused after sorting, there is an effect that the damaged parts can be easily replaced, and the reuse by replacing the parts becomes easy.
[0028]
Conventionally, a groove is formed at a predetermined pitch on the upper surface of a parallel urethane foam cushioning material that is hot-melt bonded to the mount, and the backlight is made of urethane foam by inserting both ends of the backlight into each groove. Although elastically supported at both ends, according to the present invention, both the cushioning material and the mount can be manufactured without increasing the conventional materials, and special processing is performed for positioning or holding the cushioning material on the bottom surface of the packaging box. Is not necessary, and hot-melt bonding is not required, so the production cost can be reduced.
[0029]
Urethane foam cushioning material is easily deformed, so care must be taken so that it does not shift or deform during bonding, but according to the present invention, the cushioning material is inserted into an upright piece cut and raised on a mount, The engaging part engages with the holding groove of the cushioning material, and a convex part is provided on the back side of the cushioning material, and a hole that fits the convex part is formed on the mount side. There is no displacement or deformation due to vibration. Therefore, easily damaged items do not directly hit the exterior case and are not damaged. In addition, there was a problem that foam was easily crushed when a little heavy thing was put on urethane foam, but the cushioning material mounting plate of the present invention is used as a cushioning material for urethane foam in order to support the weight of the upper part during use. Has a specific effect that it does not take a loading weight, facilitates storage of easily damaged items and handling them at the time of stacking, and prevents damage.
