Description

  The present invention relates to a buffer sheet and an article storage unit.

  Conventionally, packaging boxes made of cardboard or the like have been used for transporting articles such as potted plants. Such a packaging box has a certain buffer function by protecting the potted plant from the outside. However, when a potted plant is stored in such a packaging box, the potted plant may tilt or fall within the packaging box, and soil may leak from the pot, or the plant may come into contact with the packaging box and be damaged. In addition, only such a packaging box cannot provide a sufficient buffering action, and if a relatively strong impact is applied from the outside, there is a high possibility that the pots and plants are damaged.

  In order to solve such a problem, a three-dimensional object packing capable of improving the buffer function has been invented today (see JP 2013-159369 A). The packing described in this gazette includes a pair of front and rear wall portions provided facing each other so as to sandwich the bowl from the front and rear, and the front and rear wall portions have through-hole portions for fitting the outer peripheral portion of the bowl. Therefore, this packing can suppress rocking | fluctuation of a bowl to a certain extent by inserting a bowl in this through-opening part. Moreover, since this packing has the bending | flexion flap which a front-and-back wall part protrudes from the side edge of a through-hole part to a through-hole side, the side surface of a bowl is protected by this bent flap. However, in this packing, when the bowl is fitted in the through-hole portion provided in the front and rear wall portions, the side surface of the bowl projects outward from the planar position of the front and rear wall portions, so this protruding portion is another article or the like. It becomes easy to come into contact with this, and there is a high risk that this protruding portion will be damaged.

  In addition, the packing has a spacer piece projecting outward on the bottom, and the spacer piece can be accommodated in the packaging box in a state of being in contact with the corner of the packaging box. However, in this packing, when the bottom portion is fitted into the packaging box by the spacer piece provided on the bottom portion in this manner, a gap is generated between the upper portion of the packing and the packaging box, and thus the upper surface is glazed. There is a high risk that the potted plant will tilt or fall within the packaging box.

JP 2013-159369 A

  The present invention has been made in view of such inconveniences, and is provided with a cushioning sheet and an article storage unit capable of suppressing swinging of an article such as a potted plant and protecting the article from an external impact easily and reliably. It is intended to provide.

  The shock-absorbing sheet according to the present invention made to solve the above problems is a shock-absorbing sheet comprising a single cardboard sheet, assembled into a substantially U-shaped shock-absorbing body in a front view, and housed in a packaging box, An outer bottom plate that forms an outer bottom portion in an assembled state, an outer wall configuration band-shaped portion that has a pair of outer plates that are connected to both lateral sides of the outer bottom plate and that face each other in the assembled state, and the outer wall configuration An inner wall constituting band-shaped portion that is arranged in parallel with the front edge and / or rear edge of the belt-shaped portion, and the inner wall constituting band-shaped portion is connected to the outer bottom plate and has a smaller length in the left-right direction than the outer bottom plate. Inner bottom plate, a pair of first inner plates connected to both sides in the left-right direction of the inner bottom plate and facing each other in the assembled state, and connected to outer edges in the left-right direction of the pair of first inner plates and opposed to the outer bottom plate in the assembled state A pair of flat plates, and a pair of second inner plates connected to the outer edges of the pair of flat plates in the left-right direction and connected to the front and / or rear edges of the outer plates, The inner plate constitutes a storage recess that can store an article wider than the length of the inner bottom plate in the front-rear direction in the assembled state in the front-rear direction of the shock absorber and a pair of front and rear support columns that support the article from the front-rear direction. The constituent band-shaped portion further includes a tongue piece protruding from the inner edge in the front-rear direction of the support column toward the storage recess.

  The buffer sheet includes a pair of outer plates, a pair of first inner plates, a pair of outer wall constituent strips folded on the outside of the inner wall constituent strips, or the inner wall constituent strips folded on the inside of the outer wall constituent strips. The second inner plates are assembled as a buffer body by being bent into a substantially U shape in front view so that the second inner plates face each other. Since the said buffer sheet has a pair of 1st inner side plates which comprise a storage recessed part and a pair of front-back support pillar, rocking | fluctuation of an article | item can be suppressed by storing an article in this storage recessed part. Moreover, since the said buffer sheet has a tongue piece by which the said inner wall structure strip | belt-shaped part protrudes from the front-back direction inner edge of a support pillar toward a storage recessed part, it can protect the side surface of the articles | goods accommodated in the storage recessed part. . Further, the buffer sheet has a pair of outer plates, a pair of first inner plates, and a pair of second inner plates that face each other in an assembled state, and a storage recess is formed in the pair of first inner plates. Therefore, even when an article is stored in the storage recess, the pair of outer plates exist outside the both side surfaces of the article. That is, even when the cushion sheet stores an article in the storage recess, the article does not protrude outward from the pair of outer plates. Therefore, even when an impact is applied from the side of the article, the buffer sheet can weaken the impact applied to the article by the pair of outer plates. Therefore, the buffer sheet can easily and reliably protect the article from external impacts.

  The tongue pieces may project from the inner edges in the front-rear direction of the pair of front and rear support columns. Thus, by having the pair of front and rear tongue pieces protruding from the pair of front and rear support columns, the article can be held more accurately between the pair of front and rear support columns. Further, according to such a configuration, there is a possibility that a gap is formed between the pair of front and rear tongue pieces in a state in which the article is stored in the storage recess, and the article may be exposed to the outside. Since the pair of outer plates is provided on the outer side of the plate, damage to the article can be suppressed.

  The first inner plate has a pair of front and rear support pillar constituent portions disposed at a distance from the front and rear portions of the left and right side edges of the inner bottom plate, and the flat plate is a pair of front and rear support pillar constituent portions. It is good to be connected to the left and right direction outer edges. As described above, the first inner plate has a pair of front and rear support column components disposed at a distance from the front and rear portions of the left and right side edges of the inner bottom plate, and the plane plate has a pair of front and rear support columns. By being connected to the left and right outer edges of both parts, the swinging of the article stored in the storage recess can be prevented by a pair of front and rear support pillar constituent parts, and the flat plate can move a part of the article upward By covering from above, the storage state of the article can be suitably held.

  The flat plate may have a convex piece projecting toward the storage concave portion on the inner edge in the left-right direction that is continuous with the storage concave portion. As described above, since the flat plate has the convex piece protruding toward the storage concave portion on the inner edge in the left-right direction continuous with the storage concave portion, the storage state of the article can be more accurately maintained. That is, when a convex piece that protrudes toward the storage concave portion is formed on the inner edge in the left-right direction that is continuous with the storage concave portion of the flat plate, the convex piece protrudes in a direction parallel to the flat plate in the assembled state. For this reason, the convex piece is maintained in a constant posture regardless of the size and shape of the article or the posture of the article, so that the storage state of the article can be accurately maintained.

  Further, an article storage unit according to the present invention, which has been made to solve the above-described problems, includes a buffer body formed by assembling the buffer sheet, and the buffer so as to come into contact with the outer bottom portion and the pair of outer portions of the buffer body from the outside. And a packaging box for accommodating the body therein.

  Since the article storage unit includes a buffer formed by assembling the buffer sheet, the article stored in the buffer can be restrained from swinging and can be easily and reliably protected from external impacts. . Further, the article storage unit is configured such that the outer bottom portion and the pair of outer portions of the shock absorber formed by assembling the shock absorber sheet come into contact with each other by the packaging box, so that the shock absorber in the packaging box is prevented from shaking. Thus, the article can be protected accurately.

  As described above, the shock-absorbing sheet and the article storage unit of the present invention can prevent the article such as potted plants from swinging and can easily and reliably protect the article from external impacts.

[First embodiment]
<Buffer sheet>
The buffer sheet 1 in FIG. 1 is formed of a substantially square cardboard sheet. The buffer sheet 1 is assembled into a substantially U-shaped buffer body when viewed from the front, and is housed in a packaging box. The buffer sheet 1 includes a pair of outer wall constituent strips 2a and 2b and an inner wall constituent strip 3 arranged between the pair of outer wall constituent strips 2a and 2b. That is, in the buffer sheet 1, the inner wall constituting band-like portion 3 is juxtaposed at the rear edge of one outer wall constituting band-like portion 2a, and the inner wall constituting band-like portion 3 is juxtaposed at the front edge of the other outer wall constituting band-like portion 2b. ing. In addition, in the shock-absorbing body formed by assembling the shock-absorbing sheet 1 and the shock-absorbing sheet 1, “front” means one direction side of the outer wall constituent strips 2a and 2b and the inner wall constituent strip-shaped portion 3 in the short direction, "Means the opposite side. Further, “left and right” in the cushioning sheet 1 means the longitudinal direction side of the outer wall constituent strips 2 a and 2 b and the inner wall constituent strip 3, and “left and right” in the buffer means the left and right direction in the bottom. In FIG. 1, a thick solid line indicates an edge (including a cut) obtained by cutting the corrugated cardboard sheet, and a thin solid line indicates an easy folding line (ruled line) formed by embossing the corrugated cardboard sheet.

  The corrugated cardboard sheet used for the buffer sheet 1 is obtained by laminating a core base paper formed in a corrugated shape on a liner, for example, pasting a core base paper formed in a corrugated shape on a single liner. Single-sided corrugated sheet, double-sided corrugated sheet with a liner attached to the top of a single-sided cardboard sheet, double-sided corrugated sheet with a single-sided cardboard sheet laminated on one side of a double-sided cardboard sheet, on one side of a double-sided cardboard sheet A double-sided cardboard sheet in which the tops of single-sided cardboard sheets are further bonded together can be used. Among these, double-sided cardboard sheets are preferable from the viewpoint of processability, economy, durability, and the like. Further, the ridge line direction of the core of the corrugated cardboard sheet is parallel to the longitudinal direction of the pair of outer wall constituent strips 2a and 2b and the inner wall constituent strip 3.

(Outer wall component strip)
The pair of outer wall constituting band-like portions 2a and 2b constitutes a pair of outer bottom plates 4a and 4b constituting the outer bottom portion in the assembled state, and a pair of outer portions facing to each other in the assembled state connected to both lateral sides of the outer bottom plates 4a and 4b. A pair of outer plates 5a and 5b.

  The outer bottom plates 4a and 4b are formed in a substantially rectangular shape. The outer bottom plates 4a and 4b are connected to the inner wall constituting belt-like portion 3 at the front edge or the rear edge of the central portion in the left-right direction. Further, the outer bottom plates 4a and 4b have a pair of side portions extending in the left-right direction of the central portion in a front view. The outer bottom plates 4a and 4b are formed with chamfered left and right edges on the side connected to the inner wall constituting belt-like portion 3.

The lower limit of the extending length _{L 1} of the side, 3 cm are preferred, 5 cm is more preferable. In contrast, the upper limit of the extending length _{L 1} of the side, 8 cm are preferred, 6 cm is more preferable. When extending length L ₁ of the side is less than the above lower limit, the outside when accommodated article to cushion made by assembling the cushioning sheet 1, side a pair of outer plates 5a of the article, than 5b May protrude. Conversely, if the extending length L ₁ of the side exceeds the upper limit, there is a possibility that the cushion is unnecessarily large.

Outer bottom plate 4a, the lower limit of the longitudinal length _{L 2} of the 4b, 3 cm are preferred, 8 cm is more preferable. On the other hand, the outer bottom plate 4a, the upper limit of the longitudinal length _{L 2} of the 4b, 13cm are preferred, 10 cm is more preferable. Outer bottom plate 4a, the longitudinal direction length L ₂ of the 4b is less than the above lower limit, it may not be sufficiently increased the strength of the bottom of the cushion formed by assembling the cushioning sheet 1. Conversely, if the outer bottom plate 4a, the front-rear direction length L ₂ of 4b exceeds the upper limit, the assembling workability of the cushion may be lowered, there is a possibility that the buffer body is increased unnecessarily.

  The outer side plates 5a and 5b are connected to the left and right side edges of the outer bottom plates 4a and 4b. Specifically, the outer side plates 5a and 5b are connected to the side edges in the left and right direction excluding the chamfered portions of the outer bottom plates 4a and 4b, and extend laterally from the connecting portions. Since the buffer sheet 1 has such a configuration, a lower corner portion of the buffer body formed by assembling the buffer sheet 1 is formed in a chamfered shape in a plan view, thereby facilitating accommodation work in the packaging box. Is done.

  Moreover, the outer side plates 5a and 5b are connected to the second inner side plate 9 of the inner wall constituting strip-shaped portion 3 described later at the front edge or the rear edge on the outer side in the left-right direction. The outer plates 5 a and 5 b are notched at the end edge opposite to the side connected to the second inner plate 9. The outer plates 5a and 5b have such cutouts, so that the outer plates 5a and 5b are prevented from closing openings 16 and 17 to be described later when assembled on the buffer body. In addition, the outer plates 5a and 5b are folded on the outer side of the inner wall constituting band-shaped portion 3, and the inner edges (outer edges in the front-rear direction before folding) are separated from each other. That is, the total length in the front-rear direction of the outer plates 5 a, 5 b is shorter than the length in the front-rear direction of the inner wall constituting strip 3. The interval between the inner edges is equal to or greater than the width of the handle hole 53 of the packaging box 52 described later. Thereby, as for the said buffer sheet 1, the taking-out work property from the packaging box of the buffer body which assembled this buffer sheet 1 is improved.

The length L ₃ in the longitudinal direction of the outer plates 5a, 5b is not particularly limited, and can be, for example, about 20 cm to 50 cm.

(Inner wall constituent strip)
The inner wall constituting belt-like portion 3 constitutes an inner wall in the assembled state. The inner wall constituting strip 3 is connected to the outer bottom plates 4a and 4b and has a smaller length in the left-right direction than the outer bottom plates 4a and 4b, and a pair connected to both sides in the left-right direction of the inner bottom plate 6 and facing each other in the assembled state.

By holding the buffer body 21 inside, the buffer body 21 can be prevented from swinging in the vertical direction.

<Buffer body removal procedure>
Next, a procedure for taking out the buffer body 21 from the packaging box 52 will be described with reference to FIG. First, the upper portions of the pair of inner walls 24 are brought close to each other, and a finger is put into the pair of openings 16 formed in the region overlapping the pair of handle holes 53 of the packaging box 52 to grip the upper portions of the pair of inner walls 24. At this time, since the plurality of cut pieces 46 are bent inward, the upper portions of the pair of inner walls 24 can be easily approached without being blocked by the cut pieces 46.

  Subsequently, the buffer body 21 is pulled up with the upper portions of the pair of inner walls 34 being gripped. Here, by a pair of U-shaped projecting pieces 12 extending from both sides of the center portion in the front-rear direction of the inner bottom plate 6, recesses 25 are formed on both sides in the left-right direction in the center portion in the front-rear direction of the shock absorber 21, and Since the inner edges of the outer portion 23 are separated from each other by more than the width of the pair of handle holes 53, contact between the buffer body 21 and the cut piece 46 is avoided when the buffer body 21 is taken out from the packaging box 52. Therefore, the article storage unit 51 can easily and reliably take out the buffer body 21 from the packaging box 52.

<Advantages>
The buffer sheet 1 has a pair of outer plates formed by folding the outer wall constituting strips 2a and 2b outside the inner wall constituting strips 3 or folding the inner wall constituting strip 3 inside the outer walls constituting strips 2a and 2b. 5a, 5b, the pair of first inner plates 7 and the pair of second inner plates 9 are assembled as the buffer body 21 by being bent into a substantially U shape when viewed from the front so as to face each other. Since the buffer sheet 1 includes the storage recess 13 and the pair of first inner plates 7 constituting the pair of front and rear support columns 26, swinging of the article can be suppressed by storing the article in the storage recess 13. . Further, the buffer sheet 1 has tongue pieces 10 and 11 in which the inner wall constituting band-shaped portion 3 projects from the inner side in the front-rear direction of the support column 26 toward the storage recess 13, so that the articles stored in the storage recess 13 The side can be protected. Further, the buffer sheet 1 has a pair of outer plates 5a and 5b, a pair of first inner plates 7 and a pair of second inner plates 9 that face each other in the assembled state. Since the storage recess 13 is formed, even when an article is stored in the storage recess 13, the pair of outer plates 5 a and 5 b exist outside the both side surfaces of the article. That is, even when the buffer sheet 1 stores an article in the storage recess 13, the article does not protrude outward from the pair of outer plates 5a and 5b. Therefore, even when an impact is applied from the side of the article, the buffer sheet 1 can weaken the impact applied to the article by the pair of outer plates 5a and 5b. Therefore, the buffer sheet 1 can easily and reliably protect the article from external impacts.

  The buffer sheet 1 has a pair of front and rear tongue pieces 10 and 11 projecting from a pair of front and rear support columns 26, whereby the article can be more accurately held between the pair of front and rear support columns 26. Further, according to such a configuration, there is a possibility that a gap is generated between the pair of front and rear tongue pieces 10 and 11 in a state where the article is stored in the storage recess 13 and the article is exposed to the outside. Since the pair of outer plates 5a and 5b are provided outside the pair of first inner plates 7, damage or the like of the article can be suppressed.

  The shock-absorbing sheet 1 has a pair of front and rear support pillar constituent portions 14a and 14b in which the first inner plate 7 is spaced from the front and rear portions of the left and right side edges of the inner bottom plate 6 and the flat plate 8 is front and rear. Since it is connected to the left and right outer edges of both the pair of support pillar constituent parts 14a and 14b, it is possible to prevent the horizontal swing of the article stored in the storage recess 13 by the pair of front and rear support pillar constituent parts 14a and 14b. In addition, since the flat plate 8 covers a part of the article from above, the article can be prevented from swinging in the vertical direction, and the stored state can be suitably maintained.

  Since the buffer sheet 1 has the convex piece 15 that protrudes toward the storage concave portion 13 on the inner edge in the left-right direction where the flat plate 8 is continuous with the storage concave portion 13, the storage state of the article can be more accurately maintained.

  Since the article storage unit 51 includes the buffer body 21 formed by assembling the buffer sheet 1, the article stored in the buffer body 21 is restrained from swinging, and the article is easily and reliably protected from external impacts. can do. Further, the article storage unit 51 is configured such that the outer bottom portion 22 and the pair of outer side portions 23 of the cushioning body 21 formed by assembling the cushioning sheet 1 come into contact with each other by the packaging box 52. The article can be protected accurately by preventing the shock absorber 21 from shaking.
