Description

  The present invention relates to a partition sheet and a packaging material set.

  In order to divide the internal space of the cardboard box vertically and horizontally to form a plurality of housing spaces, a partition body formed from cardboard sheets is widely used.

  In particular, for example, when a plurality of bottles such as beverages and alcoholic beverages are accommodated, it is no exaggeration to say that the use of a partition that forms a space for individually accommodating the plurality of bottles is essential. In general, bottles often contain 6 (half dozen) or 12 (1 dozen) bottles in one cardboard box.

  However, in recent years, with the spread of Internet shopping, there are increasing cases where a smaller number of bottles are accommodated in one box or a plurality of types of bottles are accommodated in one box and delivered using, for example, a courier service. doing.

  In the conventional partition, when used in an empty state where nothing is accommodated in any of the accommodation spaces to be formed, the partition plate bends due to the weight of the bottle, and the bottle can move to the adjacent accommodation space. The bottle may be damaged by vibration. For this reason, when a small number of bottles are delivered, it is necessary to pack, for example, newspaper in the accommodation space that does not contain the bottles so that the partition plate does not bend.

  On the other hand, in order to make it easy to accommodate bottles having different heights in one box, there has been proposed a partition that folds a part of a partition plate to form an inner lid of an accommodation space (Japanese Patent Laid-Open No. 2011-219127). reference). In this partition, when the accommodation space in which the inner lid is formed is emptied and the bottle is accommodated in another accommodation space, the partition plate that defines the accommodation space in which the inner lid is formed is bent, and the bottle is It is thought that it can prevent moving to the accommodation space which formed.

  However, the partition described in the above publication can reinforce only the part of the partition plate that defines the space in which the inner lid is formed. If the other storage space is used in an empty state, the partition plate is bent. The bottle cannot be held securely.

JP 2011-219127 A

  In view of the above inconveniences, an object of the present invention is to provide a partition and a packaging material set that can securely hold an article even when a part of the accommodation space is used in an empty state.

  The invention made in order to solve the above-mentioned problems is a first partition which is composed of a single cardboard sheet and is arranged substantially symmetrically in the vertical direction and is divided into five partition regions in the horizontal direction by a plurality of easy folding lines. A partition sheet comprising: a forming portion and a second partition forming portion; and three bottom forming portions connecting between the partition regions at odd positions in the lateral direction of the first partition forming portion and the second partition forming portion. The first partition forming portion is a flap that is separated from an adjacent partition region at a portion opposite to the bottom forming portion at both ends of the first partition forming portion and can be bent toward the opposing partition region of the second partition forming portion. An engagement piece protruding in the vertical direction is formed at the tip of the flap, and a slit that extends in the horizontal direction and engages with the engagement piece is formed in the partition regions at both ends in the horizontal direction of the second partition forming portion. It is designed for partition walls It is a door.

  In the partition sheet, the portions opposite to the bottom forming portions of the partition regions at both ends of the first partition forming portion are separated from the adjacent partition regions, toward the opposing partition regions of the second partition forming portion. By being a flap that can be folded and engaged with the slit of the partition area facing the front end, in the partition formed by assembling the partition sheet, the engagement piece can be engaged with the slit simply by folding the flap. The partition regions at both ends can be prevented from being bent toward the facing partition forming part. Further, in the partition sheet, the three partition regions on the inner side in the lateral direction are not easily bent because the side edges on both sides in the lateral direction are held by the adjacent partition regions. For this reason, since the partition formed by assembling the partition sheet is difficult to bend each partition region, even if a part of the plurality of accommodation spaces defined by these partition regions is used in an empty state. The article can be prevented from being damaged due to the movement of the article into the adjacent accommodation space.

  The bottom forming part in the center has a pair of first tongue pieces that are biased toward the first partition forming part and protrude on both sides in the lateral direction, and the bottom forming parts at both ends are on the second partition forming part side. It is good to have the 2nd tongue piece which deviates and protrudes in the horizontal direction inside, and the 3rd tongue piece which protrudes in the 1st partition formation part side. Thus, by having the first tongue piece, the second tongue piece, and the third tongue piece, the partition regions at both ends of the first partition forming portion having the flap are adjacent to the central partition region of the second partition forming portion. By assembling so as to divide the spaces on both sides in the lateral direction, it is possible to configure a partition body that forms six accommodating spaces each having a bottom portion. Moreover, this partition body more reliably prevents the partition region at the even-numbered position in the lateral direction of the first partition forming portion from being bent inward by engaging the flap with the slit of the partition region of the second partition forming portion. be able to.

  The engaging piece may be formed at both lateral ends of the first partition forming portion, and the slit may be opened to the side of the second partition forming portion. In this way, the engaging pieces are formed at both lateral ends of the first partition forming portion, and the slits open to the side of the second partition forming portion, thereby forming the first partition forming portion and the second partition forming. The engagement pieces can be engaged with the slits relatively easily by bending of the partition regions at both ends of the part.

  The part on the opposite side to the bottom forming part of the partition area at both ends of the second partition forming part is a flap having an engagement piece, like the first partition forming part, and the second partition forming is formed in the first partition forming part. It is preferable that a slit similar to the portion is formed, the base edge of the flap is defined by a ruled line, and the slit is formed to be continuous with the bottom forming part side of the ruled line. As described above, the first partition forming portion is formed by forming the flap having the engaging piece and the slit for locking the engaging piece in both the partition regions of the first partition forming portion and the second partition forming portion. Since any of the flaps of the second partition forming portion can be used, convenience is improved.

  Moreover, another invention made | formed in order to solve the said subject is equipped with the said sheet | seat for partitions, and the sheet | seat for cardboard boxes which can be assembled in the cardboard box which can accommodate the partition which assembled the said sheet | seat for partitions. It is a packaging material set.

  As described above, the packaging material set includes the partition sheet that is assembled into a partition body in which each partition region is not easily bent, and the cardboard box sheet that can be assembled into a cardboard box that can accommodate the partition body. Even if a part of the plurality of storage spaces defined by the partition of the cardboard box is used in an empty state, it is possible to prevent the goods from moving to the adjacent storage spaces and being damaged.

  As described above, the partition sheet and the packaging material set according to the present invention can reliably hold an article even when a part of the storage space is used in an empty state.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.

[Partition sheet]
FIG. 1 shows a partition sheet 1 according to an embodiment of the present invention. The partition sheet 1 is composed of one cardboard sheet. In the partition sheet 1, the corrugated cardboard sheet is arranged such that the ridgeline of the core extends in the vertical direction in FIG. In the drawing, a thick solid line indicates an edge obtained by cutting the cardboard sheet, and a thin solid line indicates a ruled line formed by pushing the cardboard sheet.

  The corrugated cardboard sheet forming the partition sheet 1 is not only a sheet in which both sides of one core are sandwiched between a pair of liners, but also a so-called double sheet in which the core is sandwiched between three liners. A flute may be used, and so-called single-sided cardboard in which a liner is attached only to one side of the core may be used.

  The partition sheet 1 includes a first mirror forming portion 2 and a second partition forming portion 3 that are substantially mirror-shaped and disposed substantially symmetrically in the vertical direction, and the first partition forming portion 2 and the second partition forming. Three bottom forming portions 4, 5, 6 connecting the portions 3 are provided. The boundaries between the first partition forming portion 2 and the second partition forming portion 3 and the bottom forming portions 4, 5, 6 are defined by easy folding lines.

  The first partition forming part 2 and the second partition forming part 3 are divided into five partition regions (first partition region 2a, second partition region 2b, third partition region 2c, The fourth partition region 2d and the fifth partition region 2e are divided into a first partition region 3a, a second partition region 3b, a third partition region 3c, a fourth partition region 3d, and a fifth partition region 3e).

  The first partition forming unit 2 and the second partition forming unit 3 and the bottom forming units 4, 5, and 6 are easily bent, and the first partition forming unit 2 and the second partition forming unit 3 are divided into five partitions. The folding easy lines divided into regions can be formed from ruled lines formed by pushing the corrugated cardboard sheet, perforated cuts, partial slits, and combinations thereof.

  The bottom forming portions 4, 5, 6 connect between the partition regions at odd positions in the lateral direction of the first partition forming portion 2 and the second partition forming portion 3. Specifically, the bottom forming portion 4 on one side in the horizontal direction connects the first partition region 2a of the first partition forming portion 2 and the first partition region 3a of the second partition forming portion 3, The bottom forming portion 5 connects the third partition region 2c of the first partition forming portion 2 and the third partition region 3c of the second partition forming portion 3, and the bottom forming portion 6 on the other side in the horizontal direction is the first partition. The fifth partition region 2e of the forming unit 2 and the fifth partition region 3e of the second partition forming unit 3 are connected.

[Partition area]
The first partition regions 2a and 3a, the second partition regions 2b and 3b, the third partition regions 2c and 3c, the fourth partition regions 2d and 3d, and the fifth partition regions 2e and 3e that face each other in the vertical direction are in the horizontal direction. Are equal in width (interval between the folding easy lines). In addition, the first partition areas 2a and 3a and the fifth partition areas 2e and 3e, and the second partition areas 2b and 3b and the fourth partition areas 2d and 3d at the target positions in the horizontal direction have the same width in the horizontal direction. Is preferred. Typically, all the partition areas 2a, 2b, 2c, 2d, 2e, 3a, 3b, 3c, 3d, and 3e are formed to have substantially equal widths. The “substantially equal width” means that the maximum value of the difference in width between any partition regions is not more than 3 times, more preferably not more than 2 times the average thickness of the cardboard sheet.

  The partition areas 2a, 2e and the partition areas 3a, 3e at both ends in the lateral direction of the first partition forming section 2 and the second partition forming section 3 are adjacent to the partition areas 2b, 2d and partitions adjacent to the bottom forming section. The flaps 7 are separated from the regions 3b and 3d and can be folded toward the partition regions 3a and 3e of the second partition forming portion 3 or the partition regions 2a and 2e of the first partition forming portion 2 facing each other. The base edges of the flaps 7 may be defined by ruled lines 8 formed by pushing the cardboard sheet.

<Flap>
The flap 7 is formed with an engagement piece 9 protruding in the vertical direction at the tip (end opposite to the bottom forming portions 4, 5, 6). Specifically, the flap 7 may be partially cut off at the longitudinal tip so as to leave the engagement piece 9. Further, the engagement piece 9 may be formed by forming one or a plurality of cuts at the tip of the flap 7 and partially bending the tip.

  Further, the partition areas 2a, 2e, 3a, 3e at both ends of the first partition forming section 2 and the second partition forming section 3 extend in the lateral direction and can be engaged with the engaging pieces 9 of the opposing partition areas. Is formed.

  The average length in the vertical direction of the portion excluding the engagement piece 9 of the flap 7 is preferably substantially equal to the widths of the second partition regions 2b and 3b and the fourth partition regions 2d and 3d. The tip edge of the portion other than the engagement piece 9 of the flap 7 may be slightly inclined so that the length of the flap 7 increases toward the outer side in the lateral direction. In this way, by inclining the leading edge of the portion other than the engagement piece 9 of the flap 7, the engagement piece 9 is detached from the slit 10 when the partition body formed by assembling the partition sheet 1 is deformed. This can be suppressed.

  The lower limit of the inclination angle of the leading edge of the flap 7 is preferably 1 ° and more preferably 2 °. On the other hand, the upper limit of the inclination angle of the leading edge of the flap 7 is preferably 5 °, and more preferably 4 °. When the inclination angle of the front edge of the flap 7 is less than the lower limit, the effect of suppressing the detachment of the engagement piece 9 from the slit 10 may be insufficient. Conversely, when the inclination angle of the leading edge of the flap 7 exceeds the upper limit, the angle in plan view between the first partition region 3a and the second partition region 3b of the second partition forming portion 3 and the second partition forming portion It may be difficult to maintain the angle between the third partition area 3d and the third partition area 3e.

(Engagement piece)
The engagement piece 9 engages with the slit 10 in the assembled state of the partition sheet 1, so that the flap 7 is separated into the partition regions 2 a, 2 b, 2 c, 2 d, 2 e, 3 a, 3 b, 3 c, 3 d, 3 e. Is held substantially perpendicular to

  The engagement pieces 9 are preferably formed at both lateral ends of the first partition forming portion 2 and the second partition forming portion 3. In this way, by disposing the engaging pieces 9 at both lateral ends of the first partition forming portion 2 and the second partition forming portion 3, the first partition regions 2a, 3a, the fifth partition regions 2e, 3e, etc. It is relatively easy to bend and engage the engagement piece 9 with the slit 10. Further, by disposing the engaging pieces 9 at both lateral ends of the first partition forming portion 2 and the second partition forming portion 3, the length of the engaging pieces 9 that can be engaged with the slit 10 is made relatively large. be able to.

  It is preferable that the engagement piece 9 has a trapezoidal shape in which the distal end side is smaller than the proximal end side. Thus, by forming the engagement piece 9 in a trapezoidal shape, insertion into the slit 10 becomes relatively easy. Thus, when the engagement piece 9 is formed in a trapezoidal shape, the ratio of the length of the upper base on the distal end side to the length of the lower base on the proximal end side is, for example, 0.7 or more and 0.9 or less. Can do.

  The lower limit of the average width of the engagement piece 9 is preferably 15% of the width of the first partition regions 2a and 3a and the fifth partition regions 2e and 3e, and more preferably 20%. On the other hand, the upper limit of the average width of the engagement pieces 9 is preferably 40% of the width of the first partition regions 2a, 3a and the fifth partition regions 2e, 3e, more preferably 35%. When the average width of the engaging pieces 9 is less than the lower limit, the strength of the engaging pieces 9 is insufficient and the flap 7 may not be held. On the other hand, when the average width of the engagement pieces 9 exceeds the upper limit, it may not be easy to engage the engagement pieces 9 with the slits 10.

(slit)
The slit 10 is formed to be continuous with the bottom forming portions 4, 5, 6 of the ruled line 8 that defines the base end edge of the flap 7. In other words, the side edge on the leading end side of the partition area of the slit 10 is formed on the extended line of the ruled line 8. Thus, when the flaps 7 of the first partition forming part 2 and the second partition forming part 3 are used symmetrically when the flaps 7 of the first partition forming part 2 and the second partition forming part 3 are formed symmetrically, In addition, the flap 7 can be held substantially perpendicular to the partition regions 2a, 2b, 2c, 2d, 2e, 3a, 3b, 3c, 3d and 3e.

  Moreover, when the engaging piece 9 is arrange | positioned at the horizontal direction both ends, the slit 10 is good to open to the side of the 1st partition formation part 2 and the 2nd partition formation part 3 corresponding to this. Thus, when the slit 10 opens to the side of the first partition forming portion 2 and the second partition forming portion 3, the engagement of the engagement piece 9 to the slit 10 becomes relatively easy.

  The lower limit of the average width in the vertical direction of the slit 10 is preferably 1.5 times the average thickness of the corrugated cardboard sheet, and more preferably 2 times. The upper limit of the average width in the vertical direction of the slit 10 is preferably 5 times the average thickness of the corrugated cardboard sheet, and more preferably 4 times. When the average width of the slit 10 in the vertical direction is less than the lower limit, it may not be easy to engage the engagement piece 9. Conversely, when the average width in the vertical direction of the slit 10 exceeds the upper limit, the engagement piece 9 may be easily detached from the slit 10.

[Bottom formation area]
The center bottom forming part 5 has a pair of first tongue pieces 11 that are biased toward the first partition forming part 2 side and protrude on both lateral sides. The bottom forming portions 4 and 6 at both ends are biased toward the second partition forming portion 3 side and protruded inward in the lateral direction, and the third tongue piece 13 protruding toward the first partition forming portion 2 side Have

  The partition sheet 1 includes the tongue pieces 11, 12, and 13 so that the partition regions 2 a and 2 e at both ends of the first partition forming portion 2 protrude toward the second partition forming portion 3 side. The partition regions 2a, 2b, 2c, 2d, 2e, 3a, 3b, 3c, 3d, and 3e are folded and assembled into a partition. Thereby, the partition formed by assembling the partition sheet 1 includes a partition region 2c at the center of the first partition forming portion 2 and partition regions 3a and 3e at both ends of the second partition forming portion 3, so that the inner wall of the cardboard box. Adjacent to.

  The tongue pieces 11, 12, and 13 are accommodation spaces defined by the first partition region 2 a and the second partition region 2 b of the first partition forming portion 2 in the partition body formed by assembling the partition sheet 1. , The accommodation space defined by the fourth partition region 2d and the fifth partition region 2e of the first partition forming portion 2, and the second partition region 3b, the third partition region 3c and the fourth partition region of the second partition forming portion 3 A bottom is formed in the accommodation space defined by 3d. Therefore, the partition formed by assembling the partition sheet 1 has a bottom in all of the six accommodating spaces that are defined.
