Description

The present invention relates to a cushioning material used when packaging home appliances and the like. For example, a shock absorber used when packing a sensitive product such as a DVD player, DVD-RW, facsimile, audio / video, etc. into a cardboard box, after one cardboard is folded up three-dimensionally, The present invention relates to a shock absorber that is formed into a shock absorber having a shock absorbing action by folding a protrusion on a side wall.

For packing of home appliances, a foamed polystyrene packing has been widely used for the reason that excellent buffer characteristics and various shapes can be freely obtained. However, in recent years, problems such as the generation of dioxins have occurred in the disposal of waste together with resins such as vinyl chloride, making it difficult to use.

On the other hand, a means for improving the accumulated pressure strength of the outer packaging box made of cardboard is taken. There are measures such as upgrading the cardboard material to double the thickness or number of stacked sheets, but the assembly workability deteriorates and the cost increases. Accordingly, we have been aware of such trends from an early stage, and have been developing a corrugated board cushioning body that is not inferior to that of polystyrene foam. It has also been focused on improving the shock absorber mounted in the outer box to protect the product.

In order to cope with such a problem, as a result of repeatedly examining the desirable structure of the shock absorber made of corrugated cardboard, a method of folding from a single corrugated cardboard to a desired shape of the shock absorber at once is adopted. It was found that a shock absorber that can be delivered as a flat folded intermediate fold for transportation reasons and can be quickly folded from a single cardboard to a shock absorber at the site where the product is packed is easy to use.

In view of the above circumstances, the present invention is a shock absorber that is folded from a single cardboard and includes a stepped shelf for mounting home appliances and the like. An object of the present invention is to provide a buffer body having a wide range of buffer strength without attaching a separate buffer part.

In order to achieve the above-mentioned object, the present inventors pay attention to the fact that they have a buffering property by folding a part of a piece of cardboard into a U-shape, for example, at a site where an impact is applied to the product from the outside. Developed to form a U-shaped body. As a result of trial manufacture, the knowledge that the buffer strength can be adjusted in a wide range was obtained, and this was embodied. The invention of claim 1 is a method of forming a shelf by folding cardboard (100) connected through a fold. (30) A shock absorber (200) in which an inner wall (10), a ceiling (60), an outer wall (50), and a side wall (70) are formed, from above the ceiling (60). The inner wall portion (10) and the outer wall portion (50) are bent at a right angle while being overlapped, and the lower shelf portion (30) is bent at a right angle, and the inner wall portion (10) is formed in a rectangular tube shape. Upright with respect to the shelf (30) to be formed, the outer wall (50) is covered from the outside, and a plurality of U-shaped bodies (5) are formed inside the inner wall (10). It is a buffer characterized by being formed. In addition to the above feature of the invention of claim 1, the invention of claim 2 is provided with a buffer piece (54) through a fold (S3) provided in the outer wall piece (51) of the outer wall portion (50). The buffer pieces (53) and (55) are connected to each other through fold lines S1 and S2 obliquely carved on both sides of the buffer piece (54), and the buffer piece (54) is connected to the fold line (S3). The U-shaped body (5) is formed so that the buffer pieces (53), (55) are folded into the inner wall (10) from the folds (S1), (S2). ) Is formed. In the invention of claim 3, in addition to the above-mentioned feature of the invention of claim 2, in the U-shaped body (5), the notch (h) at the tip of the buffer piece (54) hits the inner wall piece 12 from the inside. The shock absorber is characterized in that the cuts (r) and (r) at the tips of the buffer pieces (53) and (55) are in contact with the inner wall piece 12 from the inside. In addition to the above-mentioned feature of the invention of claim 3, the invention of claim 4 is characterized in that the cuts (r), (r) at the tips of the buffer pieces (53), (55) are widened to the inner wall. It is a shock absorber characterized by contacting the pieces 11 and 13 from the inside. The invention according to claim 5 is a shock absorber characterized in that, in addition to the above-mentioned feature of the invention according to claim 1, a recess (H) of the back of the hand is formed in the inner wall portion (10).

The shock absorber according to the present invention has a function of safely protecting the product packed in the cardboard box. Moreover, since it transports in the state folded flat, it can not be bulky but can reduce transportation cost, and it contributes to the reduction of the storage space at the packing site, etc. In addition, there is an effect that it is possible to quickly fold up from a flat folded state to a three-dimensional shock absorber without requiring other accessories with only one cardboard.

Further folding and folding the inner wall pieces 12 and 13 from the creases B and C at right angles to the front side, and then inserting the convex pieces 19 of the inner wall pieces 12 into the slits 39 of the shelf pieces 31, The shelf piece 31 is integrally locked. This state is referred to as an intermediate folded body 105A3 and is shown in FIG. Next, the rib 74 of the right side wall 70 is made to stand upright from the part of the crease K1, and then bent from the part of the crease H to be inserted into the slit 21 and the cut j of the inner wall pieces 16, 17. This state is referred to as an intermediate folded body 105A4 and is shown in FIG. Further, the side wall piece 73 of the side wall portion 70 is bent from the portion of the fold K3, and is inserted into the gap in front of the shelf piece 34. This state is referred to as an intermediate folded body 105A5 and is shown in FIG. Next, from the state of FIG. 6, the shelf 30 and the side wall 70 are folded leftward from the folds U and folds M between the folds M3 and M4 on the right side of the shelf 30 and the shelf pieces 37 and 38, and the shelf The pieces 37 and 38 are raised at right angles so as to be hidden inside the shelf piece 32. This state is referred to as an intermediate folded body 105A6, and is shown in FIG. 7 as an L-shaped intermediate folded body that is the original shape of the buffer body. The folded state of FIG. 7 is turned upside down, and as shown in FIG. 8, two groups of bilaterally symmetric buffer pieces provided on the outer wall piece 51 are folded inside the intermediate folding body. At this time, when the buffer piece 54 is folded inward from the part of the fold S3, the cuts r of the outer wall pieces 53 and 55 are formed in an arc shape, and the folds S1 and S2 are obliquely cut, so The pieces 53 and 55 are also folded inward. Here, since the cut r of the buffer pieces 53 and 55 is arcuate, and the folds S1 and S2 are obliquely cut so that the buffer piece 54 is narrowed from the fold S3, the buffer piece 54 is made inside. When the buffer pieces 53 and 55 on both sides are folded inward, the buffer pieces 53 and 55 are easily bent. This state is referred to as an intermediate folded body 105A7 and is shown in FIG. Further, when the buffer piece 54 is folded inward until it becomes substantially perpendicular to the outer wall piece 51, the U-shaped bodies 5 and 5 are formed in the outer wall piece 51 at two locations in a U-shaped cross section symmetrically toward the inner side. This state is referred to as an intermediate folded body 105A8 and is shown in FIG. As an enlarged view of the U-shaped body 5 as viewed from above the outer wall piece 51, as shown in FIG. 10, the buffer pieces 53, 55 are folds S1 on both sides with the buffer pieces 54 bent inward at right angles. , A U-shaped cross-section 5 that is bent from the region S2 is formed. The notches 58 and 58 at the tips of the buffer pieces 53 and 55 on both sides are locked to the back sides of the cut lines b and b, respectively. Here, there is a shape effect of the corrugated cardboard cutting portion in which the notches 58 and 58 at the tips of the buffer pieces 53 and 55 are locked to the fishhook-like cuts b and b and are not easily removed. In addition, since it is stacked in the state of intermediate | middle folding body 105A1 shown in FIG. 2, and it conveys in the state which is not bulky, it can aim at reduction of transportation cost. Further, even at the site where the product is packed, the intermediate folded body 105A1 can be efficiently temporarily stored in a narrow space. The same applies to the other embodiments.

Next, the pad to be mounted on the outer box together with the left and right shock absorbers will be described. Fig. 4 is a development view of the pad 400PA. The pat cardboard 300PA having a substantially rectangular shape is provided with creases at predetermined locations, which will be described below. As shown in FIG. 11, the folds W1, W2, W3, W4, W5, W6, W7, W8, W9, W10, W11, W12, W13, W14, W15 are provided in parallel on the pad corrugated board 300PA. It is done. And pad piece 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95 is formed so that it may be surrounded by these. The pad piece 82 has a window 96, the pad piece 86 has a tongue piece 97, the pad piece 90 has a window 99, and the pad piece 87 has fins 9, 9 at both ends via folds W 10. Is provided. The pad cardboard 300PA is configured as described above, and the procedure for folding it up to the pad 400PA will be described below.

First, it is bent toward the front side so as to form a rectangular tube body from the left end along the fold in the vertical direction, and the front side of the rectangular tube body 7 is used as a pad piece 83 as shown in FIG. Next, the pad piece 87 is centered and bent from the right end along the fold in the vertical direction so as to form the square tube body 8, and the front side of the square tube body is defined as a pad piece 89. This state is referred to as a pad intermediate folded body 305PA1.

Next, by inserting the tongue piece 97 of the pad piece 86 into the inside of the cylinder into the window 96 of the pad piece 82 in the left square cylinder body 7, the square cylinder body 7 is integrally engaged with the pad pieces 85 and 86. Stopped. Here, since the tongue piece 97 extends from the fold line W7 toward the end, it is difficult to come off the window 96. Similarly, by inserting the tongue piece 98 into the window 99 of the right-side square cylinder 8 inside the cylinder, the right-side square cylinder 8 is integrally locked to the pad piece 87. Here, since the tongue piece 98 has fins 9 and 9 at both ends, the tongue piece 98 is not easily detached from the window 99 because it expands in the rectangular tube body 8. This state is called a pad 400PA and is shown in FIG. The left recess V1 is a space in which the protruding product terminals are accommodated when the product 600 is later assembled into the outer box 500.

Similar to the intermediate folded body 105A8 described above, the other intermediate folded body 105a8 is also folded up symmetrically. These intermediate folds are assembled into the outer box 500 as a left and right set, and a pad 400PA is assembled so as to be sandwiched between them, and then the product 600 is placed thereon. The product 600 is placed on the shelf pieces 31 and 31 of the shelf portions 30 and 30 of the intermediate folding bodies 105A8 and 105a8, and this state is shown in FIG. Here, the inner wall portion 10 of the intermediate folding body stands upright with the side wall of the outer box 500 as the back, and the shelf 30 bent at a right angle to the inner wall portion 10 is placed on the bottom surface of the outer box 500. Next, each ceiling piece in the ceiling part 60 opened upward is folded inward into a rectangular tube shape, thereby folding the left and right shock absorbers 200A and 200a. At this time, a rectangular tube formed by bending the ceiling pieces 61, 62, 63, 64 into the corner C 1 formed at a right angle between the inner wall 10 and the side wall 70 is fitted so that the upper surface becomes the ceiling piece 61. However, the product 600 indicated by the two-dot chain line is pressed from above, and this state is shown in FIG.

As described above, the shock absorbers 200A and 200a are mounted on the left and right in the outer box 500, and the products are inserted into the shelf portions 30 of these shock absorbers. This state is shown in FIG. 16 as a section taken along the line AA-AA in FIG. 15, and the buffering action of the U-shaped section 5 will be described below. A shock absorber is attached to the left and right ends of the outer box 500, and the product 600 is placed thereon. Below the buffer body 200 </ b> A, a rectangular tube body including shelf pieces 31, 32, 33 of the shelf portion 30 and an outer wall piece 51 is formed, and an end portion of the product 600 is placed on the shelf piece 31. On the right side of the product 600, the U-shaped cross-section 5 is folded inside the inner wall piece 12. The end face of the impact piece 54 forming the U-shaped cross-section 5 and the left end face of the impact pieces 53 and 55 on both sides are in contact with the inner wall piece 12 on the product 600 side. That is, referring to FIGS. 8 and 9 and FIG. 16, the buffer pieces 53 and 55 are connected to each other through folds S1 and S2 which are obliquely cut on both sides with the buffer piece 54 in the middle. When the buffer piece 54 is bent at a substantially right angle from the crease S3, the buffer pieces 53 and 55 on both sides are bent and formed to expand toward the center of the buffer body 200A. At this time, the cut h at the tip of the buffer piece 54 abuts on the inner wall piece 12 from the inside, and the linear tip on the extension of the arc-like cut r in the buffer pieces 53 and 55 also abuts on the inner wall piece 12 from the inside. On the other hand, the side surfaces of the buffer pieces 53 and 55 formed so as to expand toward the end are in contact with the inner wall pieces 11 and 13 from the inside. Above the product 600, a rectangular tube body formed of ceiling pieces 61, 62, 63 and 64 of the ceiling portion 60 is formed, and the ceiling piece 63 faces the product 600 side. In this way, the right end portion of the product 600 is protected from an external impact by the inner wall piece 12 and the U-shaped cross section 5, and the lower portion of the product 600 is protected by the rectangular tube of the shelf 30. The upper part is protected by a rectangular tube body of the ceiling part 60. In addition, although the product 600 is mounted on the square cylinders of the left and right shelves 30 and 30, the square cylinder of the shelf 30 has sufficient strength to support the weight of the product 600, Since a hollow is formed in this rectangular cylinder, it has a buffering action against an impact from below the exterior box 500 and protects the product 600. Further, since the U-shaped cross-sections 5 and 5 folded into the inner wall portion 10 face the product 600 in the left-right direction in the exterior box 500, the product 600 is protected against impacts from the left-right direction. Has a buffering effect. Specifically, when a large impact is applied to the U-shaped cross-section 5 from the outside, the notches 58 and breaks b provided on the impact pieces 53 and 55 on both sides of the U-shaped cross-section 5 as shown in FIG. The impact on the product 600 is mitigated by the engagement with the swaying or the U-shaped body 5 having a three-section cross-section. Although the front-rear direction of the product 600 is not shown in the cross-sectional view, as shown in FIG. 15, the front side is protected from impact from the outside by the pad 400 PA, and the front side is protected from impact by the left and right side wall portions 70. The outer wall piece 52 of the outer wall portion 50 is supported from the inside by the height P1 of the rib 74 (shown in FIG. 1) with the inner wall piece 18 further interposed therebetween, and protects the product 600 from impacts in the front-rear direction. .

In addition to the above, the buffering action of other parts will be described. A cushioning effect is provided by a combination of ruled lines and cuts provided on various pieces. For example, by cutting the cuts f and f so as to intersect the ruled line X1 provided on the shelf piece 13 of the shelf 30 shown in FIG. In addition, the ruled line X2 carved on the shelf piece 32 of the shelf portion 30 has a buffering action for protecting the product because the cardboard material is similarly buckled. In addition, the cuts g and g cut vertically so as to cross the ruled line X3 provided on the ceiling piece 62 of the ceiling portion 60 have a buffering action for protecting the product by the buckling of the cardboard piece. Here, the ruled line means a crease-shaped shallow notch made on various pieces to make it easy to buckle due to an external impact. In addition, the cardboard pieces are easily buckled by the plurality of holes 65 provided in the ceiling piece 64 of the ceiling portion 60 to protect the product. The buffering and buckling actions are the same in the other embodiments, and the ruled lines, cut lines, and holes in the developed view are omitted.

As described above, the outer box 500 is used by incorporating a pad between the left and right shock absorbers. As shown in FIG. 14, a U-shaped pad 400PA is mounted between the buffer body 200A and the buffer body 200a with the dent side facing the side wall of the exterior box 500. Below, the procedure for mounting the product 600 to the exterior box 500 is summarized, and the product 600 indicated by the two-dot chain line is placed on the shelf pieces 30 and 31 of the intermediate folding bodies 105A8 and 105a8. Next, the left and right shock absorbers 200A and 200a shown in FIG. 15 are completed by bending the respective ceiling pieces forming the ceiling portion 60 opened upward in a rectangular tube shape inward. At this time, as shown on the right side of FIG. 6, the rectangular cylinder formed by the ceiling pieces 61, 62, 63, 64 is fitted into the right-angled corner C <b> 1 formed in the side wall 70, and the product 600 Hold both ends from above. Thus, even if there is an impact from above, the product 600 is held and fixed, and the product 600 is protected from the impact. The pad 400PA is incorporated into the other side wall of the outer box 500 with the recessed side facing, but the product 600 is accommodated in a space surrounded by the left and right shock absorbers and the pad 400PA. Since a space is formed between the recess of the pad 400PA and the side wall of the outer box 500, accessories such as a CD board, an instruction manual, an adapter, a cable, and a connection cord related to the product 600 are referred to as the product 600.

The present embodiment is a modification of the first embodiment, and the main difference from the first embodiment is that when the product is held with both hands and placed on the shelf of the buffer body, the escape portion of the back of the hand is buffered. It is in the place that is provided in the body. Further, in order to enhance a buffering action against an impact from the left and right direction, a reinforcing rib is provided on the buffer body. Hereinafter, the differences from the first embodiment will be mainly described.

As shown in FIG. 17, the corrugated cardboard 100B, which is a development view of one of the pair of left and right buffer bodies 200B, is provided with folds at predetermined locations. Then, along the crease in the left-right direction, the inner wall part 10, the shelf part 30, the outer wall part 50, the ceiling part 60, and the side wall part 70 are roughly divided into five in the vertical direction. Basically, it is the same as the cardboard 100A of the first embodiment. The difference is that a window 26 is provided along the cut across the inner wall pieces 12 and 13 of the inner wall portion 10. The window 26 has a trapezoidal shape surrounded by the cuts p1, p2, p3, p4, p3, and p2. The left and right windows 23, 24 of the inner wall piece 14 are provided with ribs 27, 27 symmetrically through the folds N1, N1. In detail, the slit 31 of the shelf part 30 is provided with two slits 139 and 139 on the left and right. Corresponding to these slits, convex pieces 119 and 119 are provided above the inner wall piece 12. In addition, it is the same as that of the corrugated cardboard 100A that two groups of three buffer pieces are provided symmetrically on the left and right of the outer wall piece 51.

The left and right set of corrugated boards 100B and 100b are configured as described above, and the following items differ from the first embodiment in the procedure of folding into a buffer body. First, after the shelf 30 is bent into a rectangular tube shape, the two protruding pieces 119 and 119 are formed in two slits 139 when the inner wall piece 12 of the inner wall portion 10 is fixed to the shelf piece 31 of the shelf portion 30. 139. Second, in conjunction with the impact piece 54 being folded, the ribs 27, 27 on the left and right sides are bent at right angles from the folds N1, N1 of the inner wall piece 14 to the inside of the rectangular tube, thereby The support by the ribs 27 and 27 is formed.

FIG. 18 shows a perspective view of the intermediate folded body 105B8 bent in the same manner as in the first embodiment as seen from the back side. As in the first embodiment, the buffer pieces are folded inside the outer wall piece 51 to form the U-shaped bodies 5 and 5 symmetrically. FIG. 19 shows a partial cross section taken along arrow BB-BB. When the buffer piece 54 is folded inward at a right angle from the crease S3 in the outer wall piece 51 of the outer wall 50, the buffer pieces 53 and 55 on both sides are also bent inward. At this time, the difference from the first embodiment is that the left and right ribs 27 and 27 are bent inward at right angles from the folds N1 and N1 of the inner wall piece 14 of the inner wall portion 10, and overlap the cushion pieces 54 and 54 back to back. In this state, the cut h at the tip of the buffer piece 54 comes into contact with the inner wall piece 12 from the inside, and at the same time, the linear tip on the extension of the arc-like cut r in the buffer pieces 53 and 55 also comes into contact with the inner wall piece 12 from the inside. Similarly, the cut m at the tip of the rib 27 also comes into contact with the inner wall piece 12 from the inside. Since the product 600 indicated by the alternate long and short dash line is located outside the inner wall piece 12, the product 600 is formed by the inner wall piece 12 of the square-walled inner wall portion 10 and the U-shaped body 5 and the rib 27 on the inner side. Double protected from external impact.

Next, the pad will be described. The pad 400PB is a development view of the pad, and the pat cardboard 300PB having a substantially rectangular shape is provided with folds at predetermined locations, which will be described below. As shown in FIG. 20, the folds Z1, Z2, Z3, Z4, Z5, Z6, Z7, Z8, Z9, Z10, Z11, Z12, Z13, Z14, and Z15 are provided in parallel on the pad corrugated cardboard 300PB. It is done. Then, pad pieces 181, 182, 183, 184, 185, 186, 187, 188 and 189 are formed so as to be surrounded by these. The pad piece 182 has a window 192, the pad piece 185 has a tongue piece 193, 197, a rib 196, and a buffer piece 195, 195 with the cut t interposed therebetween, and a pad piece 190 that bends in a V shape from the fold line Z18 on the upper side. , 191. In addition, the pad piece 188 includes a window 198, and the pad piece 189 includes a rib 199. The pad corrugated board 300PB is configured as described above, and is folded up into the pad 400PB below.

FIG. 21 shows the folded pad 400PB. With the pad piece 185 as the front surface, the rectangular tube body 108 is formed on the left side and the rectangular tube body 107 is formed on the right side. In the center of the upper side of the pad piece 185, a recess V2 is formed in which the pad pieces 190, 191 are bent in a V shape from the folds Z17 and Z18. The recess V2 becomes a space for storing the remote control of the product 600 after the product 600 is assembled. Then, at the upper part of the left-sided rectangular cylinder 108, a right-angled corner C2 is formed at the front and a corner C3 is formed at the back, and a right-angled corner C4 is formed below. It should be noted that the ribs 196 and 199 act as a sticky plate inside the rectangular tube 108 to support the rectangular tube 108 from the inside. The method of locking each tongue piece to each window provided in the rectangular tube body 107 and the rectangular tube body 108 is the same as in the first embodiment. The buffer pieces 195 and 195 at the center of the pad piece 185 have a structure including a cut t at the center and folds Z7 and 8 on both sides, and form a relief portion of the protrusion of the product 600.

Similar to the above-described intermediate fold 105B8, the other intermediate fold 105b8 is also folded symmetrically. FIG. 22 shows a state in which these intermediate folding bodies are mounted on the outer box 500 as a set on the left and right sides, a pad 400PB is further incorporated, and the product 600 is placed thereon. When the pad 400PB is assembled between the left and right intermediate folds, the corner C4 is aligned with the corners of the rectangular cylindrical shelf 30 in the intermediate fold 105b8 as shown in the figure. Therefore, the positioning of the buffer body 200b can be ensured by the corner portion C4 of the pad 400PB at the lower part on the buffer body 105b8 side. Next, the product 600 indicated by a two-dot chain line is placed on the shelf pieces 31 and 31 of the respective shelf portions 30 and 30 of the intermediate folded body 105B8 and the intermediate folded body 105b8. At this time, the rectangular tube formed by bending the ceiling pieces 61, 62, and 63 of the ceiling portion 60 is fitted into the right-angled portions of the front corner portion C2 and the back corner portion C3 formed at 400PB from above. When packing the rectangular parallelepiped product 600 in the exterior box 500, the product 600 is placed on the shelf pieces 31 and 31 of the left and right shock absorbers 200B and 200b while holding the corners of the bottom surface of the product 600 with both hands. At this time, it is difficult to place the product 600 on the shelf pieces 31 and 31 because the back of the hand hits the inner wall 10 of the buffer body. In the present embodiment, the hollows H1 of the back of the hand are formed on the left and right by the windows 26 straddling the inner wall pieces 12 and 13 in the inner wall 10 of the left and right shock absorbers. The work of inserting the product 600 into the left and right shock absorbers is easy.

Next, the ceiling pieces 61, 62, 63, 64 are folded into a rectangular tube shape as the ceiling portion 60 and fitted into the right-angle portions of the corner portions C 2, C 3 of the pad 400 PB shown in FIG. This state is shown in FIG. 23 as the left and right shock absorbers 200B and 200b. At this time, since both end portions of the product 600 are pressed from above by the rectangular tubular ceiling portions 60, 60, the product 600 is reliably protected by an impact from above.

Next, a third embodiment of the present invention will be described with reference to FIGS. FIG. 24 is a development view of one of the left and right buffer bodies 200, which is a cardboard 100C.
FIG. 25 is a perspective view showing a state in which a pair of intermediate folded body 105C8, intermediate folded body 105c8, and pad 400PB in the middle of folding are assembled in the outer box 500, and the product 600 is placed thereon.

The present embodiment is a modification of the second embodiment, and the main difference from the second embodiment is that the shape of the recesses formed in the inner walls of the left and right shock absorbers is different. Hereinafter, the differences from the second embodiment will be mainly described.

As shown in FIG. 24, the corrugated cardboard 100C, which is a development view of the one pair of left and right shock absorbers 200C, is provided with folds at predetermined locations. Then, along the crease in the left-right direction, the inner wall part 10, the shelf part 30, the outer wall part 50, the ceiling part 60, and the side wall part 70 are roughly divided into five in the vertical direction. Basically, it is the same as the corrugated cardboard 100B of the second embodiment. The difference is that the inner wall piece 12 of the inner wall portion 10 is provided with opening windows 291 and 292 on the left and right sides of the inner wall piece 12 and 13 with the window 28 and the cut line n1 being symmetrical. Here, the window 28 has a rectangular shape surrounded by q1, q2, q3, and q2. The two-stage opening windows 291 and 292 have a half trapezoidal shape surrounded by the cut line n1, the fold lines B1 and B2, and other cut lines p and q.

FIG. 25 shows a state in which the intermediate folds 105C8 and 105c8 are mounted on the outer box 500 as a left and right set, and the pad intermediate fold 400B is assembled and the product 600 is placed thereon. As illustrated, a product 600 indicated by a two-dot chain line is placed on the shelf pieces 31 and 31 of the respective shelf portions 30 and 30 of the left and right intermediate folded bodies 105C8 and 105c8. At this time, the rectangular tube formed by bending the ceiling pieces 61, 62, 63 of the ceiling 60 is fitted into the right-angled corners C2 and C3 formed at 400PB from above. When packaging the rectangular parallelepiped product 600 in the exterior box 500, the product 600 is placed on the shelf pieces 31 and 31 of the left and right shock absorbers 200C and 200c while holding the corners of the bottom surface of the product 600 with both hands. The back of both hands hits the shock absorber and it is difficult to place it on the left and right shock absorbers. However, as shown in the intermediate folded body 105c8 on the right side of the figure, in the present embodiment, a hollow H2 of the back of the hand is formed across the inner wall pieces 12 and 13 in the left and right inner wall portions 10. Specifically, the hollow H2 is formed by pushing and bending the open windows 291 and 292 on both sides straddling the inner wall pieces 12 and 13 along the fold lines B, B1 and B2 to the inside of the rectangular tubular inner wall portion 10. Here, the opening window 291 is pushed and bent so as to overlap the back side of the inner wall piece 12, while the opening window 292 is bent at a right angle to act as a rib for supporting the inner wall portion 10 from the inside. In this way, the recess H2 formed in the inner wall portion 10 becomes a relief of the backs of both hands, and the work of inserting the product 600 into the left and right shock absorbers is facilitated. In addition, the opening window 292 formed by pushing and bending the opening windows 291 and 292 toward the inside of the rectangular tube-shaped inner wall portion 10 acts as a rib that supports the inner wall portion 10 from the inside. Buffers against impacts from directions.

A fourth embodiment of the present invention will be described with reference to FIGS. FIG. 26 is a development view of a pair of left and right buffer bodies 200, which is a cardboard 100D. FIG. 27 is a perspective view showing a state in which a pair of intermediate folded body 105D8, intermediate folded body 105d8, and pad 400PB in the middle of folding are assembled in the outer box 500, and the product 600 is placed thereon.

This embodiment is a modification of the second embodiment, and the main difference from the third embodiment is that the shape of the recesses formed in the inner walls of the left and right shock absorbers is different. Hereinafter, the difference from the third embodiment will be mainly described.

As shown in FIG. 26, the corrugated cardboard 100D, which is a development view of one of the pair of left and right shock absorbers 200D, is provided with folds at predetermined locations. Then, along the crease in the left-right direction, the inner wall part 10, the shelf part 30, the outer wall part 50, the ceiling part 60, and the side wall part 70 are roughly divided into five in the vertical direction. Basically, it is the same as the corrugated cardboard 100B of the second embodiment. The difference is that the windows 281 and 282 and the cut n2 are symmetrically provided on the inner wall piece 12 of the inner wall portion 10 and the opening windows 293 and 294 are provided to the left and right across the inner wall pieces 12 and 13. Here, the window 281 has a substantially triangular shape surrounded by s1, s2, and s2, and the window 282 has a substantially triangular shape surrounded by s3, s3, and s4. Further, the two-stage opening windows 293 and 294 have different shapes surrounded by the cut line n2, the fold lines B3 and B4, and the cut lines s2, s3, and s4. Here, after the product 600 is assembled, the creases B3 and B3 are cut obliquely so as to open to both sides, so that the relief of the back of both hands is formed and the breakage of the corrugated cardboard paper is prevented. There is an effect.

FIG. 27 shows a state in which the intermediate folds 105D8 and 105d8 are mounted on the outer box 500 as a left and right set, and the pad intermediate fold 400B is assembled and the product 600 is placed thereon. As illustrated, a product 600 indicated by a two-dot chain line is placed on the shelf pieces 31 and 31 of the left and right intermediate folded bodies 105D8 and 105d8. At this time, the rectangular tube formed by bending the ceiling pieces 61, 62, and 63 of the ceiling portion 60 is fitted into the right-angled portions of the front corner portion C2 and the back corner portion C3 formed at 400PB from above. When packaging the rectangular parallelepiped product 600 in the outer box 500, the product 600 is placed on the shelf pieces 31 and 31 of the left and right shock absorbers 200D and 200d while holding the corners of the bottom surface of the product 600 with both hands. It is difficult to place the product 600 between the left and right shock absorbers when the backs of both hands hit the shock absorbers. However, as shown in the intermediate folded body 105d8 on the right side of the figure, in this embodiment, a hollow H3 having a large back of the hand is formed across the inner wall pieces 12 and 13 in the left and right inner wall portions 10. Specifically, the hollow H3 is formed by pushing and bending the opening windows 293 and 294 on both sides straddling the inner wall pieces 12 and 13 along the creases B, B3, and B4 to the inside of the rectangular tubular inner wall portion 10. Here, the opening window 293 is pushed and bent so as to overlap the back side of the inner wall piece 12, while the opening window 294 is pushed and bent so as to overlap the back side of the inner wall piece 13. In this way, the recess H3 formed in the inner wall portion 10 becomes a relief of the backs of both hands, and the work of inserting the product 600 into the left and right shock absorbers is facilitated. Further, by bending the opening windows 293 and 294 toward the inside of the rectangular tubular inner wall portion 10, the folds of the folds B3 and B4 are formed to be rounded so as to represent the outline of the recess H3. When inserting the product 600 between the folded bodies 105D8 and 105d8, there is no need to cut hands.

A fifth embodiment of the present invention will be described with reference to FIGS. FIG. 28 is a development view of a pair of left and right shock absorbers 200E, which is a cardboard 100E. FIG. 29 is a perspective view of the intermediate folded body 105E5 in the middle of further folding the cardboard 100E. FIG. 30 is a perspective view of the intermediate folded body 105E6 in the middle of further folding. FIG. 31 is a perspective view showing a state in which a pair of intermediate folded body 105E8 and intermediate folded body 105e8 in the middle of folding are assembled in the outer box 500, and a product 600 is placed thereon. FIG. 32 is a perspective view showing a state in which the product 600 is folded up into the buffer bodies 200E and 200e so as to be pressed from above.

The present embodiment is a modification of the second embodiment, and the main difference from the second embodiment is that side walls are provided at both longitudinal ends of the left and right shock absorbers. Hereinafter, the differences from the second embodiment will be mainly described.

As shown in FIG. 28, the corrugated cardboard 100E, which is a development view of the one pair of left and right shock absorbers 200E, is provided with folds at predetermined locations. Then, along the crease in the left-right direction, the inner wall part 10, the shelf part 30, the outer wall part 50, the ceiling part 60, and the side wall part 70 are roughly divided into five in the vertical direction. Basically, it is the same as the cardboard 100A of the first embodiment. The difference is that a side wall 70 is provided at the left end in addition to the right end side wall 70 in the longitudinal direction of the shock absorber. A side wall 70 is located on the left side of the ceiling 60, and is divided into ceiling pieces 71, 72, 73 and ribs 74 through fold lines K1, K2, K3 as shown in the figure. Further, shelf pieces 35 and 35 are provided on both sides of the shelf piece 32 in the shelf portion 30, and further provided on the left and right sides of the shelf pieces 37 and 38 via the folds U and U between the left and right shelf pieces 32 and 35. In addition, it is the same as that of the corrugated cardboard 100A that three buffer pieces are provided on the left and right sides of the outer wall piece 51.

The left and right set of cardboards 100E and e are configured as described above, and the following is the difference from the second embodiment in the procedure of folding into the shock absorber. Side wall portions 70 are formed at both left and right ends, and the side wall piece 73 is bent from the crease K3 and inserted into the gap in front of the shelf piece 34, and the state of the intermediate folded body 105E5 is shown in FIG. Next, from the state of the intermediate folding body E5, the side wall 70 is raised to the center at a right angle from the fold line U between the fold lines M3 and M4 and the shelf pieces 37 and 38. At this time, it is different from the first embodiment in that it is raised from the right and left to the center at right angles and the side wall portions 70 and 70 are formed on both sides. This state is referred to as an intermediate folded body 105A6, and is shown in FIG. 30 as an L-shaped intermediate folded body that serves as a prototype of the buffer body. When the product 600 is mounted on the outer box 500, the intermediate folded body is formed with a dent H2 that serves as a relief of the back of the hand, as in the second embodiment. FIG. 31 shows a state in which the intermediate folded body is mounted on the exterior box 500 as a set on the left and right sides, and the product 600 is placed thereon. When packing the rectangular parallelepiped product 600 in the exterior box 500, the product 600 is placed on the shelf pieces 31 and 31 of the left and right shock absorbers 200E and 200e while holding the corners of the bottom surface of the product 600 with both hands. At this time, it is difficult to place the product 600 on the shelf pieces 31 and 31 because the back of the hand hits the inner wall 10 of the buffer body. In the present embodiment, the hollows H1 of the back of the hand are formed on the left and right by the windows 26 straddling the inner wall pieces 12 and 13 in the inner wall 10 of the left and right shock absorbers. The work of inserting the product 600 into the left and right shock absorbers is easy. Next, the ceiling pieces 61, 62, 63, 64 are folded into a rectangular tube shape as the ceiling portion 60 and sandwiched from above the product 600. This state is shown in FIG. 32 as left and right shock absorbers 200E, 200e. At this time, since both end portions of the product 600 are pressed from above by the rectangular tubular ceiling portions 60, 60, the product 600 is reliably protected by an impact from above.

The procedure for mounting the product on the exterior box is summarized, and the product 600 indicated by a two-dot chain line is placed on the shelf pieces 31 and 31 of the intermediate folding bodies 105E8 and 105e8. Next, each of the ceiling pieces in the ceiling portion 60 opened upward is folded inward into a rectangular tube shape to be folded into the left and right shock absorbers 200E and 200e. At this time, the rectangular tube formed by the ceiling pieces 16, 62, 63 is fitted into the right-angled corner C1 formed in the side wall 70 shown in FIG. 30, and the product 600 is securely pressed from above. Here, four corner portions C1 are formed at the front and rear of the left and right shock absorbers, respectively. Thus, even if there is an impact from above, the product 600 is held and fixed, and the product 600 is protected from the impact.

A sixth embodiment of the present invention will be described with reference to FIGS. FIG. 33 is a development view of a pair of left and right shock absorbers 200, which is a corrugated cardboard 100F. FIG. 34 is a perspective view showing a state in which the shelf 30 is bent inward while standing up to the buffer body 200 and is brought upright.

The present embodiment is a modification of the second embodiment, and the main difference from the second embodiment is that a flap 40 is provided at the end of the shelf piece 33 in the shelf section 30. Hereinafter, the differences from the second embodiment will be mainly described.

As shown in FIG. 33, the corrugated cardboard 100F, which is a development view of one of the pair of left and right shock absorbers 200, is provided with folds at predetermined locations. Then, along the crease in the left-right direction, the inner wall part 10, the shelf part 30, the outer wall part 50, the ceiling part 60, and the side wall part 70 are roughly divided into five in the vertical direction. Basically, it is the same as the corrugated cardboard 100B of the second embodiment. The difference is that a flap 40 is provided at the end of the shelf piece 33 in the shelf 30. Specifically, the shelf 30 is divided into three pieces 31, 32, and 33, and a flap 40 is provided on the right end of the shelf piece 33 through an oblique crease M <b> 5.

The pair of left and right cardboards 100F, f is configured as described above, and the following is the difference from the first and second embodiments in the procedure of folding into a shock absorber. In the folded state of the buffer body of the present embodiment corresponding to FIG. 6 of the first embodiment, the shelf portion 30 is moved from the right folds M3 and M4 of the shelf piece 32 and the fold U portion between the shelf pieces 37 and 38. Wake up at a right angle to the front left. That is, the rectangular tube body including the shelf pieces 34, 35, and 36 is bent at a right angle toward the front left side so as to be recessed from the portion of the fold lines M4, U, and M3 in a dogleg shape. At this time, since the flap 40 is bent outward from the portion of the crease M5, as shown in FIG. 34, the corner of the fold F between the shelf piece 35 and the shelf piece 36 bends with the flap 40 as a guide surface, and the right shelf The square cylinder composed of the pieces 34, 35, 36 smoothly enters the inside of the square cylinder composed of the left shelf pieces 31, 32, 33.

A seventh embodiment of the present invention will be described with reference to FIGS. FIG. 35 is a development view of a pair of left and right shock absorbers 200, which is a cardboard 100G. FIG. 36 is a perspective view showing a state where the ribs are provided in two stages. FIG. 37 is a perspective view showing a state in which the side wall 70 is inserted into the shelf 30. FIG. 38 is a perspective view showing a state in which the outer wall piece is inserted into the shelf 30. FIG. 39 is a perspective view showing a state where the outer wall piece has been inserted into the side surface of the shelf 30.

The present embodiment is a modification of the second embodiment. The main difference from the second embodiment is that the side wall 70 is provided with a two-step rib and the side wall 70 has a convex piece. It exists in the place inserted in the slit 140 with which the shelf piece of the shelf part 30 is equipped. Further, an outer wall piece that covers the side of the buffer body is provided outside the outer wall portion 50. Hereinafter, the differences from the second embodiment will be mainly described.

As shown in FIG. 35, the corrugated cardboard 100G, which is a development view of one of the pair of left and right shock absorbers 200, is provided with folds at predetermined locations. Then, along the crease in the left-right direction, the inner wall part 10, the shelf part 30, the outer wall part 50, the ceiling part 60, and the side wall part 70 are roughly divided into five in the vertical direction. Basically, it is the same as the corrugated cardboard 100B of the second embodiment. One of the differences is that an outer wall piece that covers the side surface is provided outside the outer wall portion 50. Specifically, the outer wall piece 151 is located on the outer left side of the outer wall piece 51 via a fold line X, and the fold line G is located above this. An outer wall piece 152 is provided via The second difference is that the ribs 741 and 742 are provided in two stages on the side wall portion 70 via the fold line K1, and more specifically, the rib 741 is further provided on the left side of the side wall piece 71 via the fold line K1. A rib 742 is provided below this via a crease K4, and the vertical height P2 of the rib 741 is greater than the height P3 of the rib 742.

The left and right set of corrugated boards 100G and g are configured as described above, and the difference from the first and second embodiments in the procedure of folding into the buffer is as follows. In the folded state of the cushioning body of the present embodiment corresponding to FIG. 5 of the first embodiment, in this embodiment, instead of the rib 74, the rib 741 of the right side wall portion 70 is a portion of the fold K1 as shown in FIG. The rib 742 is further folded from the portion of the crease K4. Next, the rib 741 and the rib 742 are overlapped and bent from the portion of the fold line H, and inserted into the slit 121 and the cut line j of the inner wall pieces 16 and 17. At the same time, as shown in FIG. 37, the plate-like convex piece 219 provided in the side wall piece 72 of the side wall 70 is inserted into the thin slit 140 provided in the shelf 34 of the shelf 30. The fitting state between the convex piece 219 and the slit 140 is tight. In this way, since the plate-like convex pieces are inserted into the thin grooves, the side wall portion 70 and the shelf portion 30 are firmly joined, making it difficult to separate them. The outer wall piece 52 of the outer wall portion 50 is supported from the inside by the ribs 741 and the heights P2 and P3 of the ribs 742 with the inner wall piece 18 therebetween, and protects the product 600 from impacts in the front-rear direction. In this case, since the heights P2 and P3 of the rib 741 and the rib 741 are different, it has a two-stage buckling action due to an impact.

The second difference from the second embodiment is that an outer wall piece that covers the side surface is provided outside the outer wall portion 50.
