Description

  The present invention relates to a box sheet.

  As a sheet for a box that can be assembled in a packaging box, four side panels that are connected in the left-right direction and constitute a square cylindrical part during assembly, a lid flap that extends from the upper edge of the four side panels, and four side surfaces Corrugated cardboard sheets having a bottom flap extending from the lower edge of the panel are used. This box sheet is opposed to each other by folding each pair of lid flaps and bottom flaps extending inward from the pair of side panels facing each other in a state in which a rectangular cylindrical portion is constituted by four side panels. Each pair of lid outer flaps and bottom outer flaps extending from the other pair of side panels is folded inward and assembled to the packaging box by abutting the tips.

  However, in this packaging box, the flaps inside the lid and the flaps outside the lid, and the flaps inside the bottom and the flaps outside the bottom are likely to interfere with each other. Therefore, in this packaging box, the flap outside the lid and the flap outside the bottom easily bulge outward due to the reaction force of the flap inside the lid and the flap inside the bottom. As a result, this packaging box may be unintentionally opened at the abutting portion between the front ends of the flaps outside the lid and the abutting portion between the front ends of the flaps outside the bottom. In addition, when the packaging boxes are stacked, cargo collapse is likely to occur due to swelling of the outer lid flap and the outer bottom flap.

  In view of such problems, today, the position of the easy folding line formed on the base end side of the flap inside the lid is made lower than the easy folding line formed on the base end side of the flap outside the lid, and the outside of the lid There has been proposed a configuration in which a weakly bent portion with reduced bending strength is provided below the easy folding line of the flap (see Japanese Patent Application Laid-Open No. 2005-14969).

JP 2005-14969 A

  However, in the packaging box described in the above publication, the position of the easy folding line formed on the base end side of the flap inside the lid is lower than the easy folding line formed on the base end side of the outer flap. For example, when another packaging box is stacked on the upper side of the packaging box, stress tends to concentrate on the base end portion of the flap outside the lid. Further, this packaging box is provided with a weakly bent portion below the easy folding line formed on the base end side of the flap outside the lid, and the strength on the base end side of the flap outside the lid is weakened. . For this reason, this packaging box is likely to be crushed due to insufficient strength on the base end side of the outer lid flap when other packaging boxes are stacked.

  The present invention has been made in view of such inconveniences, and can suppress unintentional opening of the butted portion of the flap but also load collapse in the stepped state while suppressing a decrease in strength in the assembled state. Providing a box sheet is an issue.

  A box sheet according to the present invention made to solve the above-mentioned problems is a first side panel which is composed of a single sheet and is connected from one side to the other side in the left-right direction and constitutes a rectangular cylindrical part during assembly. A second side panel, a third side panel, a fourth side panel, four lid flaps extending from the upper edge of the first side panel to the fourth side panel, and the first side panel to the fourth side panel. Four bottom flaps extending from the lower edge of the box sheet, and can be assembled into a box shape, each at the boundary between the first side panel to the fourth side panel and the lid flap and the bottom flap. An easy folding line is formed, and the easy folding line is one end in the width direction on the base end side of the inner surface of at least one of the four lid flaps and the four bottom flaps. Thin portion of the strip to opposite ends of the direction are formed.

  The box sheet is formed with easy folding lines at the boundaries between the first side panel to the fourth side panel and the lid flap and the bottom flap, and these easy folding lines are not formed in steps. In addition, a decrease in strength in the assembled state can be suppressed. Further, the box sheet has the above-mentioned folding easy line as one end in the width direction on the base end side of the inner surface of at least one of the four lid flaps and the four bottom flaps, and both side ends of each flap in the longitudinal direction. Therefore, when the flaps on the side where these thin portions are formed are vertically stacked, interference between the flaps is weakened. Therefore, the box sheet can suppress unintentional opening of the butted portion of the flap in the assembled state and load collapse in the stacked state.

  It is good to have the inclination part which thickness becomes large gradually toward the extending direction front end side of the flap in which this thin part is formed in the other end side of the width direction of the said thin part. As described above, the thin portion is thinned in the assembled state by having an inclined portion whose thickness gradually increases toward the leading end side in the extending direction of the flap where the thin portion is formed on the other end side in the width direction of the thin portion. It can suppress that a part bends along the boundary of the extension direction front end side of a flap. For this reason, it is possible to suppress a decrease in strength due to bending of the thin portion.

  The thickness of one end in the width direction of the thin portion may be gradually reduced toward the boundary between the flap in which the thin portion is formed and the side panel to which the flap is connected. Thus, the thickness of one end in the width direction of the thin portion is gradually reduced toward the boundary between the flap where the thin portion is formed and the side panel to which the flap is connected. It can be accurately folded at the boundary between the flap and the side panel, whereby the shape of the packaging box assembled can be kept stable, and interference between the flaps can be more accurately suppressed.

  The ratio of the width of the thin portion to the length of the flap in the extending direction is preferably 0.1 or more and 0.4 or less. Thus, when the ratio of the width of the thin portion to the length of the flap in the extending direction is within the above range, the strength reduction due to the thin portion is suppressed while sufficiently suppressing interference between the flaps. be able to.

  The ratio of the average thickness of the thin portion other than the inclined portion to the sheet thickness is preferably 0.3 or more and 0.8 or less. As described above, the ratio of the average thickness of the thin portion other than the inclined portion to the sheet thickness is within the above range, thereby sufficiently suppressing interference between the flaps, and the strength caused by the thin portion. Can be suppressed.

  In the present invention, the “left-right direction” refers to the horizontal direction in the assumed general usage of a packaging box formed by assembling box sheets, and “upper” and “lower” are assumed. Although it means the upper and lower sides in a general use mode, it is not intended to limit the orientation when the packaging box is used. “Inner surface” means an inner surface of a packaging box formed by assembling box sheets.

  As described above, the box sheet according to the present invention can suppress unintentional opening of the butted portion of the flap and load collapse in the stacked state while suppressing a decrease in strength in the assembled state.

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

[First embodiment]
<Box sheet>
The box sheet in FIG. 1 is composed of one sheet. The box sheet is connected from one side to the other side in the left-right direction, and constitutes a rectangular cylindrical part at the time of assembly, the first side panel 1, the second side panel 2, the third side panel 3, and the fourth side panel 4. And four lid flaps extending from the upper edges of the first side panel 1 to the fourth side panel 4 (first lid outer flap 5, first lid flap 6, second lid outer flap 7 and second lid inner Flaps 8), and four bottom flaps (first bottom outer flap 9, first bottom inner flap 10, second bottom outer flap 11 and second bottom flaps) extending from the lower edges of the first side panel 1 to the fourth side panel 4. 2 bottom flaps 12). Further, the box sheet includes an adhesive margin 13 connected to an end edge of the first side panel 1 opposite to the side connected to the second side panel 2. The box sheet is configured to be assembled into a box shape, and specifically, configured to be assembled to the packaging box 21 of FIG. 3 of the A type (citrus box type).

  The box sheet includes a boundary between the first side panel 1 to the fourth side panel and the four lid flaps 5 to 8 and a boundary between the first side panel 1 to the fourth side panel 4 and the four bottom flaps 9 to 12. Are formed with easy-to-bend lines 14a and 14b, respectively. The four folding easy lines 14a formed at the boundary between the first side panel 1 to the fourth side panel 4 and the four lid flaps 5 to 8 are arranged in a straight line as a whole (that is, the four folding lines 14a). The easy wire 14a is not arranged in a stepped manner). Also, the four fold easy lines 14b formed at the boundary between the first side panel 1 to the fourth side panel 4 and the four bottom flaps 9 to 12 are linearly arranged as a whole (that is, 4 The two easy-bending lines 14b are not arranged in steps. In FIG. 1, a thick solid line indicates an edge formed by cutting the sheet, and a thin solid line indicates a ruled line formed by pushing the sheet.

  The sheet used for the box sheet is not particularly limited as long as it has a strength sufficient to maintain the shape of the packaging box 21 formed by assembling the box sheet. For example, paper such as corrugated cardboard or cardboard Examples thereof include a sheet made of synthetic resin, a sheet made of synthetic resin, a laminated sheet of a sheet made of paper and a sheet made of synthetic resin. Among them, a paper sheet is preferable from the viewpoint of processability, impact absorbability, handleability, recyclability, economy, and the like, and a cardboard sheet is particularly preferable. The corrugated cardboard forming the box sheet is obtained by bonding a core formed of a base paper into a corrugated shape to a liner, for example, a single side in which the core formed in a corrugated shape is bonded to a single liner Corrugated cardboard sheet, double-sided cardboard sheet with a liner attached to the top of a single-sided cardboard sheet, double-sided cardboard sheet with a single-sided cardboard sheet laminated with one-sided cardboard sheet, single-sided cardboard on one side of a double-sided cardboard sheet A double-sided corrugated cardboard sheet in which the tops of the 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. In addition, the average thickness of the sheet used for the box sheet can be appropriately set as necessary, and can be set to, for example, 1.5 mm or more and 8 mm or less. When the sheet is a double-sided cardboard sheet, The average thickness of the sheet can be 5 mm, for example.

(Side panel)
The first side panel 1 to the fourth side panel 4 are each formed in a substantially rectangular shape. The first side panel 1 and the third side panel 3 are formed in substantially the same shape. The second side panel 2 and the fourth side panel 4 are formed in substantially the same shape. The vertical lengths of the first side panel 1 to the fourth side panel 4 are equal. Further, the left and right lengths of the first side panel 1 and the third side panel 3 are larger than the left and right lengths of the second side panel 2 and the fourth side panel 4. That is, the box sheet includes the first side panel 1 and the third side panel 3 as a pair of long side panels, and the second side panel 2 and the fourth side panel 4 as a pair of width side panels. Yes.

  The first side panel 1 to the fourth side panel 4 first fold the first side panel 1 on the inner surface of the second side panel 2, and then fold the fourth side panel 4 on the inner surface of the third side panel 3, The paste margin 13 is attached to the inner surface of the fourth side panel 4 to be connected endlessly. The first side panel 1 to the fourth side panel 4 are connected in an endless manner, the first side panel 1 and the third side panel 3 face each other, and the second side panel 2 and the fourth side panel 4 are A square cylindrical part is constituted by being spread so as to face each other. In addition, adhesion of the glue margin part 13 to the 4th side surface panel 4 can be performed using an adhesive agent, a stapler, etc., for example. In the box sheet, normally, the first side panel 1 to the fourth side panel 4 are connected in an endless manner, and the inner surface of the first side panel 1 is in close contact with the inner surface of the second side panel 2. 4 is provided to the user with the inner surface of 4 in close contact with the inner surface of the third side panel 3.

  A procedure for assembling the packaging box 21 from a state in which the first side panel 1 to the fourth side panel 4 constitute a rectangular tubular portion will be described. First, in a state where the rectangular tubular portion is constituted by the first side panel 1 to the fourth side panel 4, the pair of bottom flaps 10 and 12 are bent inward, and then the pair of bottom flaps 9 and 11 are inside. The bottom is formed by bending the tips and butting the tips together. Further, the pair of flaps 6 and 8 inside the lid is bent inward, and then the pair of flaps 5 and 7 outside the lid is bent inward and the tips are brought into contact with each other to form a lid. Thereby, the packaging box 21 of FIG. 3 is assembled. Although not shown, the packaging box 21 is generally applied with an adhesive tape along the joint between the tips of the pair of outer lid flaps 5, 7 and the joint between the tips of the pair of bottom outer flaps 9, 11. Wearing, bonding a pair of outer flaps 5 and 7 and a pair of inner flaps 6 and 8, and a pair of bottom outer flaps 9 and 11 and a pair of bottom flaps 10 and 12 with an adhesive Keeps the sealed state.

  The box sheet has foldable lines 14a and 14b in the width direction on the base end side in the extending direction of the inner surfaces of the four lid flaps 5 to 8 and the base end side in the extending direction of the inner surfaces of the four bottom flaps 9 to 12. Strip-shaped thin portions 15a and 15b having both ends of each of the flaps 5 to 12 in the longitudinal direction are formed. Hereinafter, the thin portions 15a and 15b will be described. The thin portions 15a formed on the four lid flaps 5 to 8 and the thin portions 15b formed on the four bottom flaps 9 to 12 have the same specific shape except for the formation locations. Therefore, only the thin part 15a formed in the four lid flaps 5 to 8 will be described below. Further, the thin portions 15a formed on the four lid flaps 5 to 8 are the same except that the lengths in the longitudinal direction are different based on the differences in the lengths in the left and right directions of the first side panel 1 to the fourth side panel 4. It is formed. Therefore, in FIG. 2, only the thin part 15a formed in the first outer lid flap 5 is illustrated.

(Thin part)
The thin portion 15a is formed in a rectangular shape whose longitudinal direction is the left-right direction. Moreover, the thin part 15a is smaller in thickness than the area other than the thin part 15a of the lid flaps 5 to 8 in the entire area. The thin portion 15 a prevents the pair of outer flaps 5 and 7 and the pair of inner flaps 6 and 8 from interfering with each other in the assembled state of the packaging box 21. Specifically, as shown in FIG. 4, the box sheet has thin inner surfaces on the base end side of the pair of lid flaps 6 and 8 and inner surfaces on the base end side of the pair of lid flaps 5 and 7. It is depressed by the part 15a. Therefore, in the packaging box 21, the pair of outer flaps 5, 7 and the pair of outer flaps 6, 8 are continuous from the second side panel 2 and the fourth side panel 4 of the pair of lid flaps 6, 8 that are likely to interfere with each other. Interference between the pair of outer flaps 5 and 7 and the pair of inner flaps 6 and 8 in the portion, particularly the portion continuous from the corners of the second side panel 2 and the fourth side panel 4 is suppressed. More specifically, since the inner surface of the pair of lid flaps 6 and 8 is recessed, the box sheet has a pair of lid flaps 6 and 8 in the assembled state. The reaction force caused by the overlap with 5 and 7 is weakened. Moreover, since the thin part 15a is continuously formed from the boundary between the pair of outer flaps 5 and 7 and the first side panel 1 and the third side panel 3, the pair of outer flaps 5 and 5 are assembled in the assembled state. 7 and the outer surfaces of the pair of lid flaps 6 and 8 abut on the distal end side of the thin portion 15a of the pair of lid outer flaps 5 and 7, and abut on the proximal end side of the pair of lid outer flaps 5 and 7. hard. Therefore, the box sheet can suppress the base end side of the pair of outer lid flaps 5 and 7 from bulging outward due to the reaction force of the pair of inner flaps 6 and 8 in the assembled state.

  As shown in FIG. 2, the thin portion 15 a is gradually moved toward the other end side in the width direction (the leading end side in the extending direction of the first lid outer flap 5) and toward the leading end side in the extending direction of the first outer lid flap 5. Have an inclined portion 16a having a large thickness. Further, the thin portion 15a is configured as a flat portion 17a having a substantially equal thickness except for the edge portion on one end side continuous from the bendable line 14a. Since the box sheet has the inclined portion 16a, the thin portion 15a can be prevented from being bent along the boundary on the front end side in the extending direction of the first lid outer flap 5 in the assembled state. Therefore, the box sheet can suppress a decrease in strength due to the bending of the thin portion 15a.

  The thickness of one end side in the width direction of the thin portion 15a gradually decreases toward the boundary between the lid flaps 5 to 8 and the side panels 1 to 4. In this way, the box sheet is such that the thickness of one end side in the width direction of the thin portion 15a gradually decreases toward the boundary between the lid flaps 5 to 8 and the side panels 1 to 4, and thus the side panel in the assembled state. 1 to 4 and lid flaps 5 to 8 can be accurately folded, whereby the shape of the packaging box 21 can be kept stable, and the pair of outer flaps 5 and 7 and the pair of lid flaps. 6 and 8 interference can be suppressed more accurately.

  The lower limit of the ratio of the width of the thin portion 15a to the length in the extending direction of the lid flaps 5 to 8 is preferably 0.10, and more preferably 0.15. On the other hand, the upper limit of the ratio of the width of the thin portion 15a to the length in the extending direction of the lid flaps 5 to 8 is preferably 0.40, and more preferably 0.35. If the ratio is less than the lower limit, the interference between the pair of outer flaps 5 and 7 and the pair of inner flaps 6 and 8 may not be sufficiently suppressed in the assembled state. Conversely, when the ratio exceeds the upper limit, the width of the thin portion 15a becomes unnecessarily large, and the strength of the lid flaps 5 to 8 may be reduced.

  The lower limit of the ratio of the average thickness T2 of the region other than the inclined portion 16a of the thin portion 15a to the sheet thickness T1 is preferably 0.3, and more preferably 0.4. On the other hand, the upper limit of the ratio of the average thickness T2 of the region other than the inclined portion 16a of the thin portion 15a to the sheet thickness T1 is preferably 0.8, and more preferably 0.7. If the ratio of the average thickness is less than the lower limit, the thickness of the thin portion 15a becomes unnecessarily small, and the strength of the lid flaps 5 to 8 may be lowered. Conversely, if the ratio of the average thickness exceeds the upper limit, the interference between the pair of outer flaps 5 and 7 and the pair of inner flaps 6 and 8 may not be sufficiently suppressed in the assembled state.

  The width L of the thin portion 15a can be appropriately set according to the size of the box sheet. As a minimum of width L of thin part 15a, 2 mm is preferred, for example, and 4 mm is more preferred. On the other hand, the upper limit of the width L of the thin portion 15a is preferably 70 mm, for example, and more preferably 50 mm. If the width L of the thin portion 15a is smaller than the lower limit, the interference between the pair of lid flaps 5 and 7 and the pair of lid flaps 6 and 8 may not be sufficiently suppressed in the assembled state. Conversely, if the width L of the thin portion 15a exceeds the upper limit, the strength of the lid flaps 5 to 8 may be unnecessarily lowered.

  The lower limit of the ratio of the width L2 of the inclined portion 16a to the width L1 of the flat portion 17a is preferably 0.2, preferably 0.3, and more preferably 0.5. On the other hand, the upper limit of the ratio of the width L2 of the inclined portion 16a to the width L1 of the flat portion 17a is preferably 0.8, and more preferably 0.7. If the ratio is less than the lower limit, the inclination angle of the inclined portion 16a with respect to the plane direction of the sheet becomes too large, and the lid flaps 5 to 8 may be easily bent at the inclined portion 16a. On the contrary, when the ratio exceeds the upper limit, the width of the inclined portion 15a becomes unnecessarily large, and the strength of the lid flaps 5 to 8 may be insufficient.

  The lower limit of the inclination angle of the inclined portion 16a with respect to the plane direction of the sheet is preferably 1 ° and more preferably 3 °. On the other hand, the upper limit of the inclination angle of the inclined portion 16a with respect to the plane direction of the sheet is preferably 20 ° and more preferably 10 °. If the inclination angle is smaller than the lower limit, the width of the inclined portion 16a becomes unnecessarily large, and the strength of the lid flaps 5 to 8 may be insufficient. On the contrary, if the inclination angle exceeds the upper limit, the lid flaps 5 to 8 may be easily bent at the inclined portion 16a.

<Advantages>
The box sheet is formed with easy folding lines 14a and 14b at the boundaries between the first side panel 1 to the fourth side panel 4 and the lid flaps 5 to 8 and the bottom flaps 9 to 12, respectively. Since the wires 14a and 14b are not formed in steps, it is possible to suppress a decrease in strength in the assembled state. In addition, the box sheet has folding easy lines 14a and 14b at one end in the width direction on the base end sides of the inner surfaces of the four lid flaps 5 to 8 and the four bottom flaps 9 to 12, and both sides of each of the flaps 5 to 12 Since the strip-shaped thin portions 15a and 15b whose ends are both ends in the longitudinal direction are formed, the interference between the flaps 5 to 12 when the flaps 5 to 12 are stacked up and down is weakened. Therefore, the box sheet can suppress unintended opening of the butted portions of the flaps 5 to 12 in the assembled state.

  Since the interference between the flaps 5 to 12 in the state where the flaps 5 to 12 are vertically stacked is suppressed, the box sheet can easily keep the outer surfaces of the lid portion and the bottom portion in a horizontal state in the assembled state. Therefore, the box sheet is excellent in stability when the packaging boxes 21 are stacked and used. Moreover, since the said sheet | seat for boxes can suppress interference of flaps 5-12 in the state which accumulated the flaps 5-12 up and down, a cover part and a bottom part can be easily formed with comparatively weak force. Furthermore, since the inner surface of the four lid flaps 5 to 8 and the four bottom flaps 9 to 12 are depressed, and the outer surfaces of these flaps 5 to 12 are not depressed, the box sheet looks good in the assembled state. Can be prevented.

[Other Embodiments]
In addition, the box sheet | seat which concerns on this invention can be implemented in the aspect which gave the various change and improvement other than the said aspect. For example, the box sheet may have the above-described thin portion formed on one of four lid flaps and four bottom flaps.

  The thin portion preferably has the above-described inclined portion on the front end side in the extending direction of the flap, but this inclined portion is not necessarily provided. In addition, it is preferable that the thickness of the thin part gradually decreases toward the boundary between the flap and the side panel. For example, the bottom part of the easy folding line and the flat part of the thin part have the same thickness. It may be formed.

  The widths of the thin portions formed on the four lid flaps and the thin portions formed on the four bottom flaps are not necessarily the same. In the box sheet, for example, the width of the thin portions provided in the pair of lid flaps and the pair of bottom outer flaps may be larger than the width of the thin portions provided in the pair of lid flaps and the pair of bottom flaps. Good.

  As described above, the box sheet according to the present invention can suppress unintentional opening of the butted portion of the flap and load collapse in a stacked state while suppressing a decrease in strength in the assembled state. It is suitable as a sheet for boxes for storage and transportation.
