Description

  The present invention relates to a box sheet.

  A box body assembled from a cardboard sheet or the like for storage, transportation, etc. of articles is widely used. Among them, a pair of length side panels and a pair of width side panels alternately connected in the left and right direction are connected in a square tube shape, and a pair of bottom inner flaps extending from the lower edge of the pair of width side panels and a pair of lengths A pair of bottom outer flaps extending from the lower edge of the face panel are folded inward to form a bottom, and a pair of inner lid flaps extending from the upper edge of the pair of width face panels and the upper edge of the pair of length face panels A box body of a type A (a so-called orange box type) assembled by forming a lid by bending a pair of lid outer flaps extending from the inside is most frequently used.

  Usually, each flap in the corrugated sheet is partitioned by a rectangular groove. However, in the box body formed by assembling this corrugated cardboard sheet, gaps are generated at the four corners of the lid and the bottom due to the gap formed between the adjacent flaps.

  Therefore, today, a configuration has been proposed in which the proximal end portions of adjacent flaps are partitioned by slits (cuts) narrower than the groove (see Utility Model Registration 3172 907).

Utility model registration 3172907 gazette

  In the corrugated cardboard sheet described in the above-mentioned publication, adjacent flaps are divided by a rectangular cutting groove and a slit (cut) which is narrower than the cutting groove. This corrugated board sheet can suppress that a crevice is formed in four corners of a lid part and a bottom part in an assembly state by dividing the base end parts of adjoining flaps by a slit.

  However, when assembling the lid and the bottom of the box, the corrugated sheet may interfere with the proximal end of the inner flap and the proximal end of the outer flap. Therefore, this corrugated sheet has room for further improvement so that it can be easily assembled into a box.

  This invention is made in view of such a problem, and makes it a subject to provide the sheet | seat for boxes which can suppress that a clearance gap is formed in a box, aiming at facilitation of an assembly.

  The sheet | seat for boxes which concerns on this invention made in order to solve the said subject is connected with the other side from the one side of the left-right direction, and the 1st length surface panel assembled in square cylinder shape, 1st width surface panel, 2nd A length side panel and a second width side panel, a pair of outer flaps extending from an end edge of the pair of length side panels in the vertical direction, and a extension side from the one side end edge of the pair of width side panels A sheet for a box which can be assembled in a box shape, comprising a pair of inner flaps, wherein the inner flaps and the base ends of the outer flaps adjacent to the inner flaps are the width surface panel and the length surface The slits are defined by linear slits that extend continuously from the boundary between the panels, and the slits extend from the proximal side to the distal side of the inner flap and the outer flap so that the outer flap is partitioned by the slits. I am inclined to side.

  In the case of the box sheet, the inner flaps and the base ends of the outer flaps adjacent to the inner flaps are separated by linear slits continuously extending from the boundary between the width surface panels and the length surface panels. In the case where the pair of inner flaps and the pair of outer flaps are folded inward in this order in assembling the box body, a gap does not easily occur between the flaps. Moreover, when the sheet | seat for the said box spreads it in square cylinder shape, after connecting said pair of length surface panels and a pair of width surface panels endlessly, or when bending said pair of inner flaps and a pair of outer flaps inside In addition, the proximal ends of these flaps are less likely to interfere with each other. Therefore, the said sheet | seat for boxes can suppress that a clearance gap is formed in a box, achieving facilitation of an assembly.

  It has a groove which is wider and rectangular than the slit which divides the inner flap and the outer flap at the tip end side than the slit, and the slit is a corner on the outer flap side divided by the groove at the bottom of the groove It is good to be connected to the department. Thus, it has a groove that is wider and rectangular than the slit that defines the inner flap and the outer flap at the tip end side than the slit, and the slit is separated by the groove at the bottom of the groove. By being connected to the corner on the flap side, interference between the adjacent flaps can be suppressed more reliably.

  As distance D1 between the both ends of the said slit on the basis of an up-down direction, 10 mm or more and 30 mm or less are preferable. As described above, when the distance D1 between both ends of the slit with reference to the vertical direction is within the above range, formation of a gap in the box is sufficiently suppressed, and the facilitation of assembly is promoted. be able to.

  As an inclination angle of the said slit on the basis of an up-down direction, 5 degrees or more and 20 degrees or less are preferable. As described above, when the inclination angle of the slit with reference to the vertical direction is in the above range, the facilitation of assembly can be promoted while sufficiently suppressing the formation of a gap in the box. .

The vertical length of the pair of outer flaps is L [mm], the horizontal length of the first width surface panel is W [mm], and the distance between both ends of the slit relative to the horizontal direction is D2 [mm] When it is set, it is good to satisfy the following formulas (1) and (2).
2 / W <L ≦ 2 / W + D2 × 2 (1)
1 ≦ D2 ≦ 3 (2)

  This makes it easy to form a gap between the ends of the pair of outer flaps in addition to the pair of inner flaps and the pair of outer flaps while facilitating the assembly of the box. It can be suppressed.

  In the present invention, "left-right direction" means the horizontal direction in the assumed general use mode of the box body formed by assembling the box sheet, and "upper" and "lower" are assumed. The upper and lower sides in the general use mode are meant, but it is not intended to limit the use direction of the box. "Inside" refers to the inside of a box formed by assembling a box sheet, and "outside" refers to the outside of a box formed by assembling a box sheet.

  As explained above, the sheet | seat for boxes which concerns on this invention can suppress that a clearance gap is formed in a box, achieving facilitation of an assembly.

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

[Box sheet]
The sheet | seat for boxes of FIG. 1 consists of a sheet | seat of 1 sheet. The sheet | seat for the said box is connected with the other side from the one side of the left-right direction, and it assembles into the square cylinder shape 1st length surface panel 1, 1st width surface panel 2, 2nd length surface panel 3, and 2nd width surface panel 4 and a pair of lid outer flaps extending from the upper edge of the pair of length surface panels 1, 3 (a first lid outer flap 5a extending from the upper edge of the first length surface panel 1, and a second length A second lid outer flap 5b extending from the upper edge of the face panel 3 and a pair of inner lid flaps extending from the upper edge of the pair of width panel 2 (extending from the upper edge of the first width panel 2) The first lid inner flap 6a, and the second lid inner flap 6b extending from the upper edge of the second width surface panel 4, and a pair of bottoms extending from the lower edge of the pair of length surface panels 1, 3 Outer flap (a first bottom outer flap 7a extending from the lower edge of the first length face panel 1, and a second length face panel A second bottom outer flap 7b) extending from the lower edge of the lower cover, and a pair of inner bottom flaps extending from the lower edge of the pair of width side panels 2, 4 (first extending from the lower edge of the first width side panel 2) A bottom inner flap 8a and a second bottom inner flap 8b extending from the lower edge of the second width surface panel 4 are provided. The first length side panel 1, the first width side panel 2, the second length side panel 3, and the second width side panel 4 are connected in this order from one side to the other side in the left-right direction. Moreover, the said sheet | seat for boxes is provided with the glue margin 9 connected with the side edge on the opposite side to the connection side with the 1st width surface panel 2 of the 1st length surface panel 1. FIG. In FIG. 1, a thick solid line indicates a cutting line formed by cutting the sheet, and a thin solid line indicates a ruled line formed by pushing one side of the sheet.

  The box sheet can be assembled into a box shape. The assembly procedure of the said sheet | seat for boxes is demonstrated.

  First, the first length surface panel 1 is folded on the inner surface side of the first width surface panel 2, and the second width surface panel 4 is folded on the inner surface side of the second length surface panel 3. Then, the adhesive margin 9 is attached to the inner surface on the other side in the left-right direction of the second width surface panel 4 (the opposite side to the connection side with the second length surface panel 3). Thereby, as shown in FIG. 2, a pair of length surface panels 1 and 3 and a pair of width surface panels 2 and 4 are connected endlessly. The sheet | seat for the said box is provided to a user (user of a box) in this state. The adhesive margin 9 can be attached to the second width surface panel 4 using, for example, an adhesive, a stapler or the like.

  Next, as shown in FIG. 3, a pair of length surface panels 1 and 3 and a pair of width surface panels 2 and 4 connected in an endless manner are spread in a square tube shape, and a pair of bottom inner flaps 8a and 8b are provided. Is folded at a substantially right angle inside, and then the bottom is assembled by bending a pair of bottom outer flaps 7a and 7b at a substantially right angle. Further, as shown in FIG. 4, the pair of lid inner flaps 6a, 6b is bent at substantially right angle inside, and the pair of lid outer flaps 5a, 5b is bent at substantially right angle inside to assemble the lid portion. Thus, a box body of the A type (so-called orange box type) is assembled. A sealing tape, for example, is attached to the butt between the ends of the pair of bottom outer flaps 7a and 7b and the butt of the ends of the pair of lid outer flaps 5a and 5b.

  The sheet used for the sheet for the box is not particularly limited as long as the sheet has strength enough to maintain the shape of the box formed by assembling the sheet for the box, and is made of paper such as cardboard sheet, cardboard etc. A sheet, a synthetic resin sheet, a laminated sheet of a paper sheet and a synthetic resin sheet, and the like can be mentioned. Among them, a paper sheet is preferable from the viewpoint of processability, shock absorption, handleability, recyclability, economy and the like, and a corrugated sheet which can easily increase the buckling strength is particularly preferable. Corrugated cardboard for forming the sheet for a box is one in which a core formed of a base paper in a corrugated shape is bonded to a liner, and for example, one side of a corrugated core formed on one liner Corrugated sheet, double-sided corrugated sheet with double-sided corrugated sheet with double-sided corrugated sheet with single-sided corrugated sheet laminated to one side of double-sided corrugated sheet with double-sided corrugated sheet with double-sided corrugated sheet The double-sided corrugated cardboard sheet etc. which further bonded the step top of the sheet together are mentioned. Among these, a double-faced cardboard sheet is preferable in terms of processability, economy, durability and the like.

  The pair of length panels 1, 3 are formed in a rectangular shape and substantially the same shape. The pair of width surface panels 2 and 4 are formed in a rectangular shape and substantially the same shape. The left-right direction length of a pair of length surface panels 1 and 3 is larger than the left-right direction length of a pair of width surface panels 2 and 4. The lengths in the vertical direction of the pair of length panels 1, 3 and the pair of width panels 2, 4 are approximately equal.

  The left-right direction length of the pair of length panels 1, 3 can be appropriately set based on the size etc. of the articles housed in the box body, but can be, for example, 15 cm or more and 50 cm. The left-right direction length of the pair of width surface panels 2 and 4 can be appropriately set based on the size etc. of the articles housed in the box body, but can be, for example, 10 cm or more and 40 cm or less. The vertical length of the pair of length panels 1, 3 and the pair of width panels 2, 4 can be appropriately set based on the size etc. of the articles housed in the box body, for example, 5 cm or more and 20 cm or less It can be done.

  The pair of lid outer flaps 5a, 5b are formed in a rectangular shape and substantially the same shape. The pair of in-lid flaps 6a, 6b are formed in a rectangular shape and substantially the same shape. The vertical length L of the pair of lid outer flaps 5a, 5b is the same as the vertical length of the pair of lid inner flaps 6a, 6b.

  The base ends of the in-lid flaps 6a, 6b and the out-of-lid flaps 5a, 5b adjacent to the in-lid flaps 6a, 6b are continuous from the boundary between the width surface panels 2, 4 and the length surface panels 1, 3. It is divided by the linear slit 11a-11c extended. Specifically, the base end 6c of the first lid inner flap 6a and the base end 5c of the first lid outer flap 5a form the boundary between the first width surface panel 2 and the first length surface panel 1 And the base end 6c of the first lid inner flap 6a and the base end 5d of the second lid outer flap 5b are separated by the first width surface panel 2 and the second A base end 6d of the second inner lid flap 6b and a base end 5d of the second outer lid flap 5b are separated by a straight second slit 11b continuously extending from the boundary between the length panel 3 and the second inner lid 6b. Are separated by a straight third slit 11 c extending continuously from the boundary between the second width surface panel 4 and the second length surface panel 3. The slits 11a to 11c are inclined toward the lid outside flaps 5a and 5b divided by the slits 11a to 11c from the base end side to the tip end side of the in-lid flaps 6a and 6b.

  In the sheet for the box, the base ends 6c and 6d of the in-lid flaps 6a and 6b and the base ends 5c and 5d of the out-of-lid flaps 5a and 5b adjacent to the in-lid flaps 6a and 6b, respectively And since it is divided by the linear slit 11a-11c continuously extended from the boundary line between the length surface panels 1 and 3, as shown in FIG. 4, a pair of lid inside flaps 6a and 6b and a pair of lid outsides With the flaps 5a and 5b bent inward in this order, between the base ends 6c and 6d of the pair of lid inner flaps 6a and 6b and the base ends 5c and 5d of the pair of lid outer flaps 5a and 5b ( That is, it is hard to produce a crevice in four corners of a lid of a box. In addition, when the sheet for a box is opened in a square cylindrical shape after connecting the pair of length surface panels 1 and 3 and the pair of width surface panels 2 and 4 in an endless shape, the pair of in-lid flaps 6a and 6b and the pair When the lid outer flaps 5a and 5b are bent inward, the base ends 6c and 6d of the pair of lid inner flaps 6a and 6b and the base ends 5c and 5d of the pair of lid outer flaps 5a and 5b do not easily interfere with each other. . Therefore, the said sheet | seat for boxes can suppress that a clearance gap is formed in a box, achieving facilitation of an assembly.

  The sheet for the box is provided with the in-lid flaps 6a, 6b and the out-lid flaps 5a, 5b at the tip end side (the end in the extension direction of the in-lid flaps 6a, 6b and the out-lid flaps 5a, 5b) than the slits 11a to 11c. It has grooves 12a to 12c which are wider and rectangular than the slits 11a to 11c for partitioning. The grooves 12a to 12c are elongated with the vertical direction as the longitudinal direction. The tips of the slits 11a to 11c (ends on the tip end side in the extension direction of the in-lid flaps 6a and 6b and the out-of-lid flaps 5a and 5b) are separated from the lid by the grooves 12a to 12c at the bottom of the grooves 12a to 12c. It is connected to the corner on the flap 5a, 5b side.

  The sheet | seat for the said box is adjacent flaps by the slits 11a-11c being connected to the corner by the side of lid outside flaps 5a and 5b divided by these grooves 12a-12c of the bottom of grooves 12a-12c. Interference can be suppressed more reliably. That is, according to this configuration, the lateral ends of the proximal ends 6c and 6d of the in-lid flaps 6a and 6b are partitioned by the slits 11a to 11c and the grooves 12a to 12c, and the in-lid flaps 6a and 6b in the lateral direction Protruding pieces 13 a to 13 c are formed to protrude outward. The projecting pieces 13a to 13c are outside the lid when the pair of length surface panels 1 and 3 and the pair of width surface panels 2 and 4 are endlessly connected (in the state of FIG. 2) into a square tubular shape. It is easy to be arrange | positioned on the outer side of the side edge of flap 5a, 5b. Therefore, as shown in FIG. 3, the sheet for a box is, in a state in which the pair of long side panels 1 and 3 and the pair of wide side panels 2 and 4 are spread in a square tube shape, the pair of lid outside flaps 5 a and 5 b and The base end portions 5c, 5d, 6c, 6d of the pair of lid inner flaps 6a, 6b are less likely to interfere with each other. Moreover, the sheet | seat for the said box is that the front-end of slit 11a-11c is connected to the said corner | angular part of groove 12a-12c, and the left-right direction of proximal end 5c, 5d of a pair of lid outside flaps 5a, 5b. The end portion of the lid inclines toward the center in the lateral direction of the lid outer flaps 5a and 5b from the proximal end side toward the distal end side. Therefore, when bending the pair of in-lid flaps 6a and 6b inward from the state in which the pair of length surface panels 1 and 3 and the pair of width surface panels 2 and 4 are spread in a square tube, the pair of box sheets The base end portions 5c, 5d, 6c, 6d of the lid outer flaps 5a, 5b and the pair of lid inner flaps 6a, 6b are less likely to interfere with each other.

  As a minimum of distance D1 between the both ends of slits 11a-11c on the basis of an up-and-down direction, 10 mm is preferred and 12 mm is more preferred. On the other hand, as an upper limit of the above-mentioned distance D1, 30 mm is preferred and 20 mm is more preferred. If the distance D1 is less than the lower limit, it may not be possible to sufficiently suppress the formation of gaps at the four corners of the lid of the box. Conversely, if the distance D1 exceeds the upper limit, the base ends 5c, 5d, 6c, 6d of the pair of lid outer flaps 5a, 5b and the pair of lid inner flaps 6a, 6b interfere with each other when assembling the box. It may be easier.

  The lower limit of the inclination angle α of the slits 11 a to 11 c with respect to the vertical direction is preferably 5 °, and more preferably 8 °. On the other hand, as an upper limit of the above-mentioned inclination angle alpha, 20 degrees are preferred and 15 degrees are more preferred. When the inclination angle α is less than the above lower limit, the pair of outer side flaps 5a, 5b and the pair of lids are expanded when the pair of length surface panels 1, 3 and the pair of width surface panels 2, 4 are expanded in a square tube shape. There is a possibility that base end parts 5c, 5d, 6c, 6d of inner flaps 6a, 6b may interfere easily. Conversely, when the inclination angle α exceeds the upper limit, the pair of in-lid flaps 6a and 6b are moved inward from the state in which the pair of long side panels 1 and 3 and the pair of wide side panels 2 and 4 are expanded into a square tube shape. When bending into two, there is a possibility that the base end portions 5c, 5d, 6c, 6d of the pair of lid outside flaps 5a, 5b and the pair of lid inside flaps 6a, 6b may easily interfere with each other.

The vertical length of the pair of lid outside flaps 5a, 5b is L [mm], the horizontal length of the first width surface panel 2 is W [mm], and the distance between both ends of the slits 11a to 11c based on the horizontal direction When it is assumed that D2 [mm], it is preferable to satisfy the following formulas (1) and (2).
2 / W <L ≦ 2 / W + D2 × 2 (1)
1 ≦ D2 ≦ 3 (2)

  Thereby, the sheet | seat for the said box is added between a pair of lid inner flaps 6a, 6b and a pair of lid outer flaps 5a, 5b, aiming at assembly facilitation of a box, and a pair of lid outer flaps 5a, 5b It can be sufficiently suppressed that a gap is formed between the tips of the two.

  The bottom outer flaps 7a and 7b have a line symmetry with the pair of outer lid flaps 5a and 5b with reference to the base end edges of the pair of lid outer flaps 5a and 5b. The pair of bottom inner flaps 8a and 8b have a line symmetrical configuration with the pair of inner lid flaps 6a and 6b with reference to the base end edges of the pair of inner lid flaps 6a and 6b. Therefore, a slit for partitioning the base ends of the bottom outer flaps 7a and 7b adjacent to the pair of bottom inner flaps 8a and 8b and the bottom inner flaps 8a and 8b, and the inner bottom flaps 8a and 8b and the bottom at the tip end of the slits The specific configuration of the groove that divides the outer flaps 7a and 7b is the same as the slits 11a to 11c and the grooves 12a to 12c described above.

  The end of the base end 5c of the first lid outer flap 5a and the end of the base end of the first bottom outer flap 7a in the left-right direction are more horizontal than the end of the first length surface panel 1 in the left-right direction. It protrudes outward in the direction. The projecting portion is inclined outward in the left-right direction from the distal end side to the proximal end side of the first lid outer flap 5a and the first bottom outer flap 7a. According to this configuration, it is possible to more reliably suppress the occurrence of gaps at the corners of the lid and the bottom of the box.
