FIGS. 20A and 20B are cross-sectional views showing the package according to the fourth embodiment of the present invention viewed from the long side and the short side. FIG. 21 is a perspective view showing a state in which an article to be packed is stored in a middle box in a package according to the fourth embodiment of the present invention. 20 (a), (b) and FIG. 21, the same or equivalent members as those in FIG. 1 are denoted by the same reference numerals, and detailed description is omitted.
The package according to the present embodiment is characterized in that the middle box includes a box body that opens upward and a lid that opens and closes an upper opening of the box body.

  For this reason, a spacer 5 as shown in FIGS. 20A and 20B is provided. The spacer 5 includes a middle box 201 and a receiving plate (backing plate) 5B, and forms a lower spacer. And the whole (middle box 201, receiving plate 5B) is formed of corrugated paper. As a result, the cushioning function of the corrugated paper itself is added to the spacer 5, and sufficient impact resistance is obtained. Further, the fact that the middle box 201 is formed of corrugated paper adds a good sliding function to the middle box. Thereby, even if the electronic device P is packed in the middle box 201 while being stored in the single packing bag F, adverse effects such as generation of paper dust due to friction between the middle box 201 and the packing bag F are suppressed. Is done.

  The inner box 201 is composed of a square box 201A opening upward and a lid 201B opening and closing the upper opening of the box 201A, and between the electronic device P and the bottom rib 3A of the corner pad 3 in a packed state. And is arranged inside the side rib 3B. And it is comprised so that receiving plate 5B and electronic equipment P can be stored. Thereby, the entire electronic device P is protected. Here, when the top surface portion receives an impact due to the fall of the package, the impact transmitted to the electronic device P is reduced by the inner box 201. On both side edges of the lid 201B, cushioning ribs 201b (projecting upward) interposed between the spacer 4 and the middle box 201 are provided by being cut and raised. Thus, the heavy electronic device P is received on the middle box 201. Here, when the shock absorbing rib 201b is deformed by receiving an impact, the impact transmitted to the electronic device P is more effectively reduced.

  The packing method in the present embodiment includes “storage of accessories in an accessory box”, “storage of items to be packed in a middle box”, and “storage of accessories and a middle box in a packing box”. Are performed sequentially, but since each of these steps is substantially the same as each step of the first embodiment, the description thereof is omitted.

Therefore, in the present embodiment, the inner box 201 having a shape that can be arranged inside the side rib 3B of the corner pad 3 at the time of packing is arranged. In this case, a single set (four) of corner pads 3 can be used for packing various kinds of electronic devices P having different masses and outer shapes.

In addition, in the present embodiment, since various types of items to be packed can be packed using a single set of corner pads, the number of inspections performed for each item to be packed, such as evaluation of dropping and vibration of the package, can be reduced. The inspection efficiency can be improved for various types of packaged objects.
Further, in the present embodiment, the molding of the lower packing cushioning member requires only a small amount of molding material, which means that a larger number of sets of packing cushioning members are used with the same size template compared to the conventional (integrated packing cushioning member). (Corner pad) can be manufactured, and there is an advantage that productivity can be improved.

Next, a fifth embodiment of the present invention will be described with reference to FIGS. FIGS. 22A and 22B are cross-sectional views showing the package according to the fifth embodiment of the present invention viewed from the long side and the short side. FIG. 23 is a perspective view illustrating a case where a middle box is placed on a corner pad of a package according to the fifth embodiment of the present invention. 22 (a), (b) and FIG. 23, the same or equivalent members as those in FIG. 1 are denoted by the same reference numerals, and detailed description is omitted.
The package according to the present embodiment is characterized in that the upper spacer and the middle box are formed integrally.

For this purpose, two upper and lower spacers 221 and 222 are provided as shown in FIGS.
The spacer 221 forms an upper spacer, and is entirely formed of corrugated paper. As a result, the cushioning function of the corrugated cardboard itself is added to the spacer 221 and sufficient shock resistance is obtained. The spacer 221 is composed of two left and right partition members 221A and 221B as shown in FIG. 23, and is integrally provided on both upper side edges of the spacer 222 (middle box).

The partition members 221A and 221B are formed by plate members having an inverted L-shaped cross section including connecting portions 221a ₁ and 221b ₁ connected to the spacer 222 and skirt portions 221a ₂ and 221b ₂ extending toward the bottom surface of the packaging box 2. It is configured to cover a part of the corner pad 3 and the spacer 222 in a packed state. In addition, buffer ribs 223 projecting (protruding sideways) toward the side walls in the packaging box 2 are cut and formed at the upper edges of the skirt portions 221a ₁ and 221b ₁ of the partition members 221A and 221B. Provided by Thereby, the cushioning function of the buffer rib 223 is added to the partition members 221A and 221B, and the impact resistance at the side portions of the partition members 221A and 221B is enhanced.

  The projecting direction of the buffer rib 223 is preferably parallel to the direction of the eyes of the spacer 221 (partition member). Accordingly, when the shock absorbing rib 223 is deformed by receiving an impact, the impact is reduced, and as a result, the impact resistance of the package 1 can be improved.

On the other hand, the spacer 222 includes a middle box 222A and a receiving plate (backing plate) 222B, and constitutes a lower spacer. And the whole (the middle box 222A, the receiving plate 222B) is formed of corrugated paper. As a result, the cushioning function of the corrugated paper itself is added to the spacer 222, and sufficient impact resistance is obtained. In addition, the fact that the middle box 222A is made of corrugated cardboard adds a good sliding function to the middle box. For this reason, even if the electronic device P is packed in the middle box 5A while being stored in the single packing bag F, adverse effects such as generation of paper dust due to friction are suppressed. The middle box 222A is a rectangular box that opens upward, is interposed between the electronic device P and the bottom rib 3A of the corner pad 3 in a packed state, and is disposed inside the side rib 3B. And it is comprised so that receiving plate 222B and electronic equipment P can be stored.
This effectively protects the bottom and side surfaces of the electronic device P.

The receiving plate 222B is entirely formed of a substantially rectangular planar body, and is configured so that the electronic device P can be placed thereon. The inner box 222A and the receiving plate 222B, the seat member in an electronic device P, the through-hole 222a for releasing the bottom protrusion P ₂ of the air intake fan and the component housing or the like, 222b are provided. Thereby, the main body of the electronic device P is stably mounted on the bottom rib 3A of the corner pad 3 via the spacer 222 (the middle box 222A and the receiving plate 222B).

  The packing method in the present embodiment includes “storage of accessories in an accessory box”, “storage of items to be packed in a middle box”, and “storage of accessories and a middle box in a packing box”. Are performed sequentially, but since each of these steps is substantially the same as each step of the first embodiment, the description thereof is omitted.

Therefore, in the present embodiment, the middle box 222A having a shape that can be arranged inside the side rib 3B of the corner pad 3 at the time of packing is arranged. In this case, a single set (four) of corner pads 3 can be used for packing various kinds of electronic devices P having different masses and outer shapes.
As a result, the lower packing cushioning member corresponding to various kinds of objects to be packed can be molded with a single template, and the molding of the lower packing cushioning member can be completed with a small amount of molding material. Can be reduced.

In addition, in the present embodiment, since various types of items to be packed can be packed using a single set of corner pads, the number of inspections performed for each item to be packed, such as evaluation of dropping and vibration of the package, can be reduced. The inspection efficiency can be improved for various kinds of packages.
Further, in the present embodiment, the molding of the lower packing cushioning member requires only a small amount of molding material, which means that a larger number of sets of packing cushioning members are used with the same size template compared to the conventional (integrated packing cushioning member). (Corner pad) can be manufactured, and there is an advantage that productivity can be improved.

In each embodiment, the case where the corner pad 3 is formed of a pulp mold material has been described. However, the present invention is not limited to this, and a thin foam sheet material made of polyethylene terephthalate (PET) or polypropylene (PP) is used. It may be formed. In this case, a corner pad having excellent elasticity and resilience can be obtained as compared with a corner pad made of a paper-based material.
Further, in each embodiment, the packaging of electronic equipment (projector) has been described as an object to be packed. However, the present invention is not limited to this. It is applicable as well as the form.

  Next, an example of how to receive an impact from the bottom surface side in the package of the present invention will be described with reference to FIG.

At the first impact, the skirt of the outer peripheral side 3F is crushed and absorbs the impact. Further, the planar portion 3E deflection through the ribs _3A 1, _{A 2,} to absorb the impact (26 view (b)).

Further it is added impact, the corner portion is supported in the inner box 5A (spacer 5) with ribs 3A ₂ arranged at the corners of the corner pad 3, the inner box 5A is deformed by the electronics P (object to be packed) Then, the impact is absorbed (FIG. 26 (c)).

  When a further impact is applied, the skirt portion of the outer peripheral side surface 3F is easily crushed by forming the inclined surface 3D at the end of the corner pad 3 on the center side of the middle box, so that the skirt portion of the outer peripheral side surface 3F is formed. Is completely crushed, and the bottom cavity 3C is crushed to absorb the impact (FIG. 26 (d)).

When an impact is further applied, the ribs 3A ₁ and A ₂ are crushed by the electronic device P via the inner box 5A, and absorb the impact (FIG. 26 (e)).

  Next, how to receive a shock on the bottom side when the inclined surface 3D is not formed will be described with reference to FIG.

  When the inclined surface 3D is not formed, the end portion is not easily crushed. Therefore, even when a plurality of impacts are applied, the skirt portion of the outer peripheral side surface 3F is not completely crushed at the end portion (FIG. 27 (b) ) (C) (d)).

Therefore, when the ribs 3A ₁ and A ₂ are crushed, the electronic device P is in a bottomed state via the middle box 5A at the end. As a result, an impact is directly applied to the electronic device P, which has an adverse effect such as breakage on the electronic device P (FIG. 27E). On the other hand, when the inclined surface 3D is formed, the skirt portion of the outer peripheral side surface 3F and the ribs 3A ₁ and A ₂ are effectively crushed to the bottom so that the buffer distance can be used effectively. Become. Therefore, a sufficient buffer capacity can be obtained without requiring a buffer distance more than necessary.

  The order of the above-described crushing changes depending on the rib structure of the corner pad 3 and the cushioning material strength of the middle box 5A. Therefore, in order to obtain the above-mentioned effect, when the drop impact is repeated, the cushioning material is gradually crushed and deformed by the synergistic effect of the cushioning of the corner pad 3 and the inner box 5A, so that a constant impact force is obtained. A structure that fits is sufficient.

  Furthermore, in the corner pad of the present invention having the above-described configuration, it is preferable that the corner pad is formed of a thin foam material or a thin cushion material formed like a pulp mold. This is because up to about 70% of the cushioning material of a thick material has a cushioning capacity by being crushed, but if an unexpected impact is applied, the cushioning material will be crushed at once and become a bottomed state , The buffering capacity is lost. However, thin foam materials and thin-walled cushioning materials, such as pulp molds, can have a structure that is gradually crushed and deformed by design, even when an unexpected shock is applied. Therefore, there is an advantage that the bottoming state does not occur at once, and the buffering ability is not lost even if a plurality of impacts are applied. By making the best use of this advantage, the cushioning distance when compared with the same cushioning capacity can be shorter than thick foam cushioning material

  Further, if the package has corner pads, unlike the foam cushioning material of the thick foamed tray system or the pulp mold cushioning material of the thin foam sheet and the integrated tray system of the papermaking system, the side portion of the packaged material Since the cushioning material is not directly arranged on the vehicle and the buffering distance can be effectively used from the individual box to the last position, the buffering distance can be further reduced.

  Furthermore, if each corner portion of the packaged object (electronic device P) is formed into a tapered (chamfered) shape or a round shape as shown in FIG. 30 by cutting or attaching another member, the corner of the spacer 5 (the middle box 5A) is formed. Since the portion has a buffering capacity, the buffering capacity of the spacer 5 can be further increased.

  Further, in the present embodiment, the inclined surface 3D has a triangular shape in which the plane from the flat portion 3E to the bottom surface is chamfered, but the present invention is not limited to this shape. For example, as shown in FIG. 28A, even if the inclined surface is not flat but round, as shown in FIG. It may be square.

  Further, it is preferable that the inclined surface 3D in the present invention is inclined more than the inclination angle of the outer peripheral side surface 3F which is an adjacent side surface. Specifically, when the outer peripheral side surface 3F has a draft taper of, for example, 5 to 7 degrees, it is preferable that the taper be a taper with a larger angle.

  Next, an example of how to receive an impact from the side surface in the package of the present invention will be described.

In the beginning of the impact, to absorb the impact outside ribs 3B _2. Furthermore an impact is applied to the outer ribs 3B ₂ is crushed deformation to absorb the impact. Furthermore an impact is applied, and the side ribs side portions 3b ₁ is crushed deformation to absorb the impact by being deformed to the intermediate rib 3G. When a stronger impact is applied, the corner of the inner box 5A is supported by the intermediate rib 3G, and the inner box 5A is bent and deformed by the electronic device P, thereby absorbing the shock. When a stronger impact is applied, the outer rib 3B ₂ , the side ribs 3b ₁ , the inner space 3C of the intermediate rib 3G, and the inner box 5A are deformed to absorb the impact.

  The order of the above-described crushing changes depending on the rib structure of the corner pad 3 and the cushioning material strength of the middle box 5A. Therefore, in order to obtain the above-mentioned effect, when the drop impact is repeated, the cushioning material is gradually crushed and deformed by the synergistic effect of the cushioning of the corner pad 3 and the inner box 5A, so that a constant impact force is obtained. A structure that fits is sufficient.

Further, in this embodiment, as shown in FIG. 29 (a), (b) , (c), (d), the side ribs 3B is an outer rib 3B ₂ with rib-shaped outward, outer the rib 3B _2, the angle from a plane perpendicular to the plane of the packing box side of the corner pad, if inclined surfaces are formed larger than the angle of the adjacent sides is formed, from the side surface The shock absorbing ability is further improved.

  Next, an example of how to receive an impact from the corner side in the package of the present invention will be described.

In the beginning of impact, by collapse of the corner portions of the packing box, crushed outer ribs 3B 2 _a pulp molded cushioning material, by deforming, cushions the. When an impact is further applied, the corner of the inner box 5A is pushed by the electronic device P, and the corner of the inner box 5A is bent, thereby absorbing the shock. Furthermore an impact is applied, together with the outer rib 3B ₂ a outer rib 3B ₂ c and outer ribs 3B ₂ b are crushed and deformed to absorb the impact. When a further shock is applied, the corner of the inner box is crushed and deformed to absorb the shock.

  The order of the above-described crushing changes depending on the rib structure of the corner pad 3 and the cushioning material strength of the middle box 5A. Therefore, in order to obtain the above-mentioned effect, when the drop impact is repeated, the cushioning material is gradually crushed and deformed by the synergistic effect of the cushioning of the corner pad 3 and the inner box 5A, so that a constant impact force is obtained. A structure that fits is sufficient.

  By the way, with the conventional integrated pulp mold tray method, under certain conditions, the side buffer distance was required about 50 mm, but by changing the pulp mold to a corner pad and a middle box method, the corner pad Due to the synergistic effect of the buffer material and the buffer provided by the middle box, the buffer performance can be improved, and as a result, the buffer distance can be reduced to about 30 mm, thereby reducing the size of the package.

  Specifically, in the integrated tray system, thin cushioning materials such as pulp mold papermaking and sheet molding have a structure that cushions with ribs, or small gaps such as ribs cause loosening. In addition, the plane portion on the upper surface of the tray becomes thick. For this reason, a tension occurs due to a side drop, the impact value increases, and a bottoming phenomenon easily occurs at that portion. In addition, under certain conditions, for example, a cushioning material having a thickness of about 50 mm, such as polystyrene foam, exhibits a buffering effect by crushing about 70% of a cushioning material of about 50 mm. As with the phenomenon, the shock value rises sharply.

  Therefore, when the corner pad according to the present invention is used, the buffer distance can be reduced, and further, the corner portion of the article to be packaged has a shape not bottomed on the inner box, and the buffer effect by the inner box is sufficiently exhibited. This allows further reduction. As a result, under certain conditions, as an example, the buffer distance could be reduced to about 30 mm, and the package size was reduced in width and depth by about 40 mm each. This will result in a significant reduction in transportation costs, especially air transportation costs.

  In addition, when the shock absorbing distance is the same as that of the thick foam cushioning material for the impact in the bottom direction, the impact performance can be repeatedly maintained by gradually crushing the ribs and the middle box of the corner pad, and it is assumed that Even if it is dropped at a height higher than the drop height, unlike a thick foam cushioning material, advantages such as the ability to absorb impact can be initially produced.

In the present invention, it is sufficient to adopt a structure in which the cushioning material is gradually crushed and deformed when the drop impact is repeated, so that the shock absorber can be settled at a constant impact force. Thus, as the ribs of the corner pads, for example, modification of the bottom ribs 3A ₂ is not formed, variation another bottom ribs are formed between the bottom ribs 3A _1, 3A _2, the outer peripheral side of the corner pads modification skirt of 3F are continuous with the end portion of the corner pad includes various modifications, such as modification of the bottom ribs 3A ₁ are continuous.
