Description

  The present invention relates to a packing shock absorber, and more particularly to a packing shock absorber using a corrugated cardboard shock absorber that is assembled by alternately folding a corrugated cardboard with a plurality of cutting lines and / or folding lines.

  When various kinds of articles are packed and used for distribution, the article may be damaged due to an impact by an external force in the distribution stage. Therefore, conventionally, when various kinds of articles are used for distribution, these articles are stored in a packaging box. Then, a foamed polystyrene resin buffer is disposed in the gap between the packaging box and the article, and the shock from the outside is absorbed by the buffer, thereby protecting the article from the impact.

  A conventional buffer using such a foamed polystyrene resin does not have a natural disintegration property when discarded after use, and therefore remains as it is for a long period of time, causing waste pollution. If incinerated, the foamed polystyrene buffer will generate high heat and damage the furnace, or it will emit black smoke and cause air pollution. Due to such environmental problems, the use of a foamed polystyrene resin buffer tends to be limited.

  Therefore, it has been proposed to assemble a shock absorber using corrugated cardboard having a natural disintegrating property. Corrugated cardboard is made from cellulose, so even if it is discarded, it will eventually be decomposed by bacteria to become water and carbon dioxide, which will not cause environmental damage. In addition, it can be decomposed and regenerated with water and can be recycled, leading to effective use of resources.

  Accordingly, the inventors of the present application disclosed a corrugated cardboard having a cutting line partially connected by a connecting portion according to Japanese Patent Laid-Open Nos. 2001-6376, 2001-72134, 2001-72138, and the like. However, a shock absorber using a shock absorbing cushion formed by alternately bending and joining in the opposite direction is proposed.

If an article is to be completely surrounded by such a shock absorber, a large shock absorber is required, and the amount of corrugated cardboard constituting such a shock absorber is greatly increased. In addition, the portion that does not require the cushioning effect is protected by a buffer body in which the corrugated cardboard is folded and laminated, and there is a problem that the use of corrugated cardboard becomes unreasonable. Further, such a buffer has a drawback that the cost is increased as compared with a conventional foamed polystyrene resin buffer.

  Therefore, according to such a shock absorber for packing, it becomes possible to assemble the shock absorber for packing by the holding plate and the shock absorber held inside the portion bent at a right angle of the side end of the holding plate. Thus, it becomes possible to effectively pack and buffer the object to be packed with a small number of buffer bodies. Accordingly, the amount of cardboard used as the main raw material of the shock absorber is reduced, and a light weight and low cost packaging shock absorber is provided. Further, it becomes possible to simplify the packaging by omitting the outer box.

  FIG. 1 and FIG. 2 show the overall configuration of the packing shock absorber according to the present embodiment. The shock absorber according to the present embodiment packs the vanity table 10 while buffering it for use in physical distribution. belongs to. Here, the vanity table 10 is configured by combining a ceramic main body 11 having a concave portion for allowing water to flow on an upper surface thereof and a rectangular parallelepiped base 12 that supports the main body 11.

  Such a vanity table 10 is sandwiched from above and below by a pair of upper and lower holding plates 15 and 19 as shown in FIGS. Here, the upper holding plate 15 is configured such that a side end 17 is bent at a right angle downward with respect to the main surface by a fold line 16 on both sides, and a pair of left and right shock absorbers 18 are disposed inside the fold line 16. It has. Similarly, the lower holding plate 19 is bent at a right angle upward by a pair of fold lines 20 so as to hold the buffer 22 inside the fold line 20. .

  In this manner, the vanity table 10 is sandwiched from above and below by the holding plate 15 that holds the pair of upper buffer bodies 18 and the holding plate 19 that holds the lower pair of buffer bodies 22. Moreover, a flat box-shaped cover 23 whose lower side is opened is mounted on the upper side, and a flat box-shaped cover 24 whose upper surface is opened is mounted on the lower side. A binding band 25 is stretched up and down from the outside of the covers 23 and 24, so that the upper and lower covers 23 and 24 and the holding plates 15 and 19 are fixed to the top and bottom of the vanity 10.

  Next, the structure of the upper holding plate 15 will be described with reference to FIG. The holding plate 15 includes fold lines 16 that are parallel to each other at a predetermined distance from both left and right ends thereof, and two pairs of cuts 29 are obliquely formed from the fold lines 16 toward both end sides. Is formed. Note that the ends of these cuts 29 are connected by a folding line 30. A region surrounded by the notch 29, the fold line 30, and the fold line 16 constitutes the engagement piece 31.

  In addition, two pairs of cuts 33 parallel to each other so as to face the engagement piece 31 via the fold line 16 are formed on the side opposite to the cut 29 with respect to the fold line 16. The end is a fold line 34. A region formed by the cut 33, the fold line 34, and the fold line 16 constitutes a locking piece 35. The position of the front end portion of the engagement piece 31 and the front end portion of the locking piece 35, which overlaps with the fold line 16, is constituted by the cutting line 36, and the part that is partially connected is broken. The combined piece 31 and the locking piece 35 are separated from each other.

  FIG. 4 shows a state in which the pair of shock absorbers 18 are held by the holding plate 15, and the left and right ends of the holding plate 15 are bent upward at right angles by the fold line 16, respectively. The buffer body 18 is attached to the inside of the wire 16, and the engagement piece 31 is engaged with an engagement recess 61 of the buffer body 18 described later from the back side, and the engagement piece 31 is locked by the locking piece 35. As a result, the buffer 18 is fixed to the holding plate 15 in a fixed state.

  Similarly, with respect to the lower holding plate 19, as shown in FIG. 5, the side end 21 is bent upward at a right angle by bending lines 20 on both sides. A pair of left and right shock absorbers 22 are held inside the fold line 20. Here again, the engaging piece 31 formed on the folding line 20 of the holding plate 19 is engaged with the engaging recess 91 of the shock absorber 22, and the engaging piece 31 is locked by the locking piece 35. Thus, the buffer 22 is held and fixed to the holding plate 19.

Next, the structure of the shock absorber 18 held inside the folding line 16 of the upper holding plate 15 will be described. The shock absorber 18 is assembled by folding the cardboard 40 shown in FIG. The cardboard 40 includes twelve plate-like portions 41 to 52 along the direction of the step, and a cutting line 53 is formed between these plate-like portions 41 to 52 . These cutting lines 53 are partially connected by a connecting portion 54. The connecting portion 54 is provided with cuts parallel to each other for cutting off the cutting line 53, and a portion between these cuts is connected. A pair of rectangular cuts 58 are formed on the side ends of the plate-like portions 41 to 43. In addition, horizontally long cuts 59 are formed in the plate-like portions 45 to 52. These cuts 59 gradually change in shape over the plate-like portions 45 to 52.

  Such a corrugated board 40 is alternately bent in the reverse direction at the cutting line 53 as shown in FIG. At this time, the portions of the cutting line 53 are connected to each other by the connecting portion 54. The plate-like portions 41 to 52 are preliminarily coated with joining means such as starch paste at positions where they are joined to each other. Therefore, when such a corrugated cardboard 40 is folded and compressed so that the plate-like portions 41 to 52 overlap each other, the buffer body 18 as shown in FIG. 8 is completed.

  The buffer body 18 is formed with a recess 60 constituting a receiving portion so as to face the outer surface by a notch 59 formed in the plate-like portions 45 to 52. The recessed part 60 receives the curved side end of the main body 11 of the vanity unit 10. Further, as shown in FIG. 9, such a buffer body 18 has a recess 61 for engagement formed by a cut 58 of the plate-like portions 41 to 44 on the back side thereof and in a corner portion. The recess 61 for engagement is wider in the inner part than the inlet on the side end side, and is formed in a trapezoidal shape when viewed from above.

  When holding the buffer body 18 on the holding plate 15, the buffer body 18 is attached to the inner side of the fold line 16 of the holding plate 15 as shown in FIG. 10. Then, the engaging piece 31 of the holding plate 15 is bent inward at the folding line 30 and engaged with the engaging recess 61 on the back side of the shock absorber 18. Since the engagement piece 31 has a substantially trapezoidal shape and substantially matches the shape of the engagement recess 61, the engagement piece 31 is correctly aligned with the engagement recess 61. Then, in this state, the locking piece 35 is bent inward at the folding line 34, so that the side of the engaging piece 31 where the tip of the locking piece 35 has already been bent inward is raised. Thus, the engagement by the engagement piece 31 is more reliably maintained. In addition, another buffer body 18 that is symmetrical with respect to FIG. 10 is housed and held by the same locking structure at the left end of the holding plate 15 and inside the folding line 16 (see FIG. 4).

Next, the structure of the lower buffer 22 will be described. The lower shock absorber 22 is assembled using a cardboard 70 shown in FIG. The cardboard 70 includes twelve plate-like portions 71 to 82, and these plate-like portions 71 to 82 are sequentially connected by a cutting line 83 having a connecting portion 84. That is, the cutting line 83 partially connects the plate-like parts 71 to 82 on both sides thereof with the connecting part 84 at the 1 to 3 positions.

  A pair of small cuts 88 each having a U-shape are formed in the plate-like portions 71 to 74. In addition, horizontally long cuts 89 are formed in the plate-like portions 76 to 82. A receiving plate 94 is connected to the notch 89 of the plate-like portion 82 via a connecting portion 95. The receiving plate 94 is provided with a locking piece 96 at its tip, and is aligned so that the locking piece 96 is locked in the locking hole 97 of the plate-like portion 75. In addition, a presser plate 98 is connected to the plate-like portion 81 via a connecting portion 99 at its side end. The holding plate 98 is provided with a protrusion 100 at its side end, and is assembled so that the protrusion 100 is locked by a rectangular locking hole 101 formed in the plate-like portion 75.

  Next, the operation of assembling the shock absorber 22 using the cardboard 70 shown in FIG. 11 will be described. As shown in FIG. 12, the plate-like parts 71 to 82 are sequentially bent in opposite directions at a cutting line 83 having the connecting part 84. And it adhere | attaches and joins with the starch paste previously apply | coated to the junction part of the plate-shaped parts 71-82. As a result, the buffer body 22 having an elongated rectangular parallelepiped shape as shown in FIGS. 13 and 14 is assembled. And the recessed part 90 which comprises a receiving part is formed of the notch 89 currently formed in the said plate-shaped parts 76-82. The concave portion 90 receives a corner ridge line portion on the lower surface of the gantry 12 of the vanity unit 10. The receiving plate 94 of the plate-like portion 82 is bent to the upper surface of the concave portion 90 by the connecting portion 95, and the locking piece 96 on the distal end side is locked in the locking hole 97 of the plate-like portion 75. Further, the presser plate 98 positioned on the side of the recess 90 is bent sideways at the connecting portion 99, and the protrusion 100 on the distal end side is locked in the locking hole 101 of the plate-like portion 75.

  In addition, as shown in FIG. 14, the buffer body 20 is formed with an engagement recess 91 by a U-shaped cut 88 of the plate-like portions 71 to 74 on the back side thereof. As shown in FIG. 15, the engaging piece 31 of the holding plate 19 is bent at the folding line 30 and engaged with the engaging recess 91. The engagement piece 31 has a substantially trapezoidal shape, and has a shape that substantially matches the engagement recess 91 that is wider in the back. If the engaging piece 31 is folded inward, the locking piece 35 is then bent inward at the fold line 34, whereby the locking piece 35 causes the distal end portion of the engaging piece 31 from the side. suppress. As a result, the engagement piece 31 is reliably maintained in a state of being engaged with the engagement portion 91, and the buffer 22 is reliably held by the inner portion of the folding line 20 of the holding plate 19 and falls off. There is nothing.

  Thus, the packing shock absorber of the present embodiment holds the pair of left and right shock absorbers 18 inside the fold line 16 of the upper holding plate 15 and the inside of the fold line 20 of the lower holding plate 19. A pair of left and right buffer bodies 22 are held in And these holding | maintenance plates 15 and 19 are mounted | worn on the upper and lower sides of the vanity table 10, as shown in FIG. Here, the receiving portion 60 of the shock absorber 18 attached to the upper holding plate 15 receives the curved portion of the upper edge of the main body 11 of the vanity unit 10. Further, the buffer 22 attached to the lower holding plate 19 receives the ridge line portion at the lower end of the gantry 12 of the vanity unit 10. In such a state, the upper cover 23 and the lower cover 24 are attached from above and below, and are bound from the outside of the upper cover 23 and the lower cover 24 by the binding band 25. In such a state, the vanity table 10 is used for physical distribution.

  According to such a shock absorber for packing, even if an external impact is applied to the vanity table 10 used for physical distribution, the shock is held by the upper and lower holding plates 15 and 19 and the shock absorbers 18 and 22 are retained. It becomes possible to protect the vanity table 10 from an impact. In addition, since the vanity table 10 is used for physical distribution in a state where the upper and lower covers 23 and 24 are attached and bound by the binding band 25, an exterior box is not required, thereby greatly increasing the cost for packaging. Can be reduced. In addition, such a packing form has four buffer bodies 18 and 22 made of corrugated cardboard as main components, and the number of components of the packaging device for packaging is greatly reduced, and packaging can be greatly rationalized.
