Description

  The present invention relates to a box sheet.

  Boxes assembled from cardboard sheets or the like are widely used for storing and transporting articles. Some of these boxes are used for storing and transporting articles and then used as containers for displaying articles. A box that can be used as a container for displaying articles is usually configured to be capable of forming an opening for taking out articles.

  As a box that can be used as such an article display container, for example, “a packaging box with improved visibility during display” (see Japanese Patent Application Laid-Open No. 2005-170474) has been proposed. This packaging box has a side panel with a cut tape that traverses in the left-right direction, and three cut lines (a central cut line and a pair of left and right sides of the central cut line) that reach the upper edge with the cut tape as one end. A cut line (hereinafter also referred to as a “side cut line”) is formed.

  The packaging box is configured such that an opening for taking out an article can be formed in the side panel by peeling off the cut tape and breaking the central cut line and one side cut line.

JP 2005-170474 A

  However, the packaging box described in the above publication tends to have insufficient buckling strength because the side panel is formed with a score line for forming an opening from the cut tape to the upper edge. Therefore, this packaging box tends to cause box crushing when other packaging boxes are stacked, for example.

  The present invention has been made in view of such inconveniences, and it is possible to form a box sheet that can form an opening for taking out an article on a side panel and can sufficiently increase the buckling strength of the box. Offering is an issue.

  The box sheet according to the present invention made to solve the above-mentioned problems is a box sheet that is composed of a single sheet and can be assembled into a box shape, and is connected to the other side from one side in the left-right direction. A substitute, a first side panel, a second side panel, a third side panel, a fourth side panel, and a fifth side panel, and a pair of first outer flaps extending from opposing edges of the first side panel; A pair of first inner flaps extending from opposing edges of the second side panel, a pair of second outer flaps extending from opposing edges of the third side panel, and the fourth side panel And a pair of second inner flaps extending from opposite edges of the first side, the paste margin portion is adhered to the outer surface on the other side in the connecting direction of the fourth side panel during assembly, and the fifth side panel is Square tube by being stacked on the inner surface of the first side panel Part is configured, the first easy-fracture line opening formed in the first side panel is formed, the second break easily line overlapping with the first break easily line during assembly to the fifth side panel is formed.

  Since the adhesive margin portion is attached to the outer surface on the other side in the connecting direction of the fourth side panel at the time of assembly, the box sheet has a fifth side panel continuous from the fourth side panel to the other side in the connecting direction. It can be stacked inside the first side panel during assembly. Further, the box sheet is formed with the first easy break line and the second easy break line which are overlapped at the time of assembly on the first side panel and the fifth side panel. By breaking the second easy-to-break line, an opening for taking out the article can be formed. In the box sheet, since the first side panel and the fifth side panel overlap at the time of assembly, the buckling strength decreases due to the first easy break line and the second easy break line in the state assembled to the box, In addition, it is possible to suppress a decrease in buckling strength after the opening for taking out the article is formed.

  The first breakable line has a convex shape whose both ends are located at a boundary with one first outer flap, and the first first outer flap has both ends connected to both ends of the first breakable line. It is preferable that a third easy-to-break line for formation and a tongue piece for starting breakage adjacent to the third easy-to-break line are formed. Thus, the first easy-to-break line has a convex shape whose both ends are located at the boundary with one first outer flap, and both ends of the first first easy-to-flap are connected to both ends of the first easy-to-break line. By forming a third easy-to-break line for forming an opening to be connected and a tongue piece for starting breaking adjacent to the third easy-to-break line, a finger is placed on the opening formed by bending the tongue piece. The first easy-to-break line and the third easy-to-break line can be easily and surely broken from the third easy-to-break line side by putting the finger on the edge of the opening and pulling it out.

  The overall shape of the first easy break line and the third easy break line is a rectangular shape having a pair of first sides parallel to the connecting direction and a pair of second sides perpendicular to the first sides. The first side and the pair of second sides formed on the first side panel are preferably curved inwardly. Thus, the overall outline of the first easy break line and the third easy break line has a pair of first sides parallel to the connecting direction and a pair of second sides perpendicular to the first sides. Due to the first side panel and the fifth side panel being bent in a rectangular shape, the first side and the pair of second sides formed on the first side panel are curved inwardly. The fall of the buckling strength of a box can be suppressed more exactly.

  The corners of the first easy break line and the third easy break line may be rounded. Thus, by rounding the corners of the first easy break line and the third easy break line, the first easy break line to the third easy break line can be reliably broken, and the first break It can suppress that a tear arises in parts other than an easy line thru | or a 3rd easy break line.

  A notch corresponding to the third easy-to-break line may be formed in the first inner flap and the second inner flap that overlap with the one first outer flap during assembly. As described above, the first inner flap and the second inner flap that overlap with the one first outer flap at the time of assembly are formed with notches corresponding to the third easy-to-break line, so that the first easy-to-break line or The article accommodated in the box can be easily taken out from the opening formed by breaking the third easy break line.

  In the present invention, “upper” and “lower” mean up and down in an assumed general usage of a box formed by assembling box sheets, and “left and right” means assumed general This means left and right in a typical use mode, but is not intended to limit the orientation of the box when used.

  As described above, the box sheet according to the present invention can form an opening for taking out articles in the side panel, and can sufficiently increase the buckling strength of the box.

[First embodiment]
<Box sheet>
The box sheet in FIG. 1 is composed of a single sheet and is configured to be assembled into a box shape. The box sheet includes an adhesive margin 1, a first side panel 2, a second side panel 3, a third side panel 4, a fourth side panel 5, and a fifth side panel connected from one side to the other side in the left-right direction. 6, a pair of first outer flaps (first upper outer flap 7 a and first lower outer flap 7 b) extending from opposing edges of the first side panel 2, and opposing ends of the second side panel 3 A pair of first inner flaps (first upper inner flap 8a and first lower inner flap 8b) extending from the edge, and a pair of second outer flaps extending from the opposite end edges of the third side panel 4 ( A second upper outer flap 9a and a second lower outer flap 9b) and a pair of second inner flaps extending from opposite edges of the fourth side panel 5 (second upper inner flap 10a and second lower inner) Flap 10b). As for the 1st side panel 2 thru | or the 5th side panel 6, the glue margin part 1 is affixed on the outer surface of the other side of the said connection direction of the 4th side panel 5, and the 5th side panel 6 is the inner surface of the 1st side panel 2. The rectangular cylindrical portion is configured at the time of assembly. 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 inner surface of the sheet.

  A procedure for assembling the box sheet into a box shape will be described. First, the connecting portion of the third side panel 4 and the fourth side panel 5 is bent, and the fourth side panel 5 and the fifth side panel 6 are folded on the inner surfaces of the second side panel 3 and the third side panel 4. Subsequently, the first side panel 2 is folded on the outer surface of the fifth side panel 6 folded on the second side panel 3, and the glue margin 1 is placed on the outer surface of the fourth side panel 5 on the other end side in the connecting direction. Adhere. The box sheet is normally provided to the user in this state.

  Next, the fifth side panel 6 and the third side panel 4 face each other with the fifth side panel 6 overlapped with the inner surface of the first side panel 2, and the second side panel 3 and the fourth side panel 5. Are expanded so as to face each other to form a rectangular cylindrical portion. Further, the first lower inner flap 8b and the second lower inner flap 10b are bent inward at a substantially right angle, and the first lower outer flap 7b and the second lower outer flap 9b are bent inward at a substantially right angle. The bottom is formed by butting the tips together. Further, the first upper inner flap 8a and the second upper inner flap 10a are bent inward at a substantially right angle, and the first upper outer flap 7a and the second upper outer flap 9a are bent inward at a substantially right angle so that the tips are butted together. To form a lid. In assembling the box, it is preferable that the first side panel 2 and the fifth side panel 6 are not attached from the viewpoint of ease of assembly. The box sheet can support the inner surface of the fifth side panel 6 by, for example, an article (not shown) accommodated in the box, so that the first side panel 2 and the fifth side panel 6 are not attached. However, the state in which the fifth side panel 6 is overlaid on the inner surface of the first side panel 2 can be stably maintained. In addition, a sealing tape is provided at the abutting portion of the first lower outer flap 7b and the second lower outer flap 9b, and the abutting portion of the first upper outer flap 7a and the second upper outer flap 9a so as to maintain the abutting state. X can be attached. Thereby, the box of FIG.2 and FIG.3 is assembled.

  The sheet used for the box sheet is not particularly limited as long as it has sufficient strength to maintain the shape of the box formed by assembling the box sheet. For example, the sheet made of paper such as cardboard sheet or cardboard is used. Examples thereof include a sheet, a synthetic resin sheet, and a laminated sheet of a paper sheet and a synthetic resin sheet. 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 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.

  The first side panel 2 to the fifth side panel 6 are each formed in a rectangular shape. The first side panel 2 and the third side panel 4 are formed in substantially the same shape. The second side panel 3 and the fourth side panel 5 are formed in substantially the same shape. The vertical lengths of the first side panel 2 to the fourth side panel 5 are substantially equal. The lateral length of the fifth side panel 6 is the lateral direction of the first side panel 2 and the third side panel 4 so that the first side panel 2 can be easily folded on the outer surface of the fifth side panel 6 when assembling the box. Slightly smaller than the length. Further, the upper edge of the fifth side panel 6 is thicker than the upper edges of the first side panel 2 to the fourth side panel 5 from the viewpoint of preventing interference with the inner flaps 8a, 8b, 10a, 10b during assembly. The lower edge of the fifth side panel 6 is positioned higher than the lower edges of the first side panel 2 to the fourth side panel 5 by the sheet thickness.

  The left and right lengths of the first side panel 2 and the third side panel 4 are larger than the left and right lengths of the second side panel 3 and the fourth side panel 5. That is, in the box sheet, the first side panel 2 and the third side panel 4 constitute a pair of long side panels. The lengths in the left-right direction of the first side panel 2 and the third side panel 4 can be set as appropriate depending on the size of the article accommodated in the box formed by assembling the box sheet, but for example, 20 cm or more and 50 cm or less. Can do. The lengths in the left-right direction of the second side panel 3 and the fourth side panel 5 can be set as appropriate depending on the size of the article accommodated in the box formed by assembling the box sheet. Can do. The vertical lengths of the first side panel 2 to the fourth side panel 5 can be set as appropriate depending on the size of the article accommodated in the box formed by assembling the box sheet. Can do.

  The first side panel 2 is formed with a first easy-to-break line 11 for forming an opening. The first easy-to-break line 11 is formed in a convex shape whose both ends are located at the boundary with one first outer flap (in this embodiment, the first upper outer flap 7a). Further, the fifth side panel 6 is formed with a second easy break line 12 that overlaps the first easy break line 11 during assembly. At the time of assembly, the second easy break line 12 is disposed so as to overlap the first easy break line 11 over the entire length. The first upper outer flap 7a is formed with a third easy break line 13 whose both ends are connected to both ends of the first easy break line 11. The first easy break line 11 to the third easy break line 13 are constituted by perforations in which a plurality of slits are arranged at intervals. Furthermore, the first upper outer flap 7a is formed with a break starting tongue piece 14 adjacent to the third easy break line 13. Specifically, in the present embodiment, the first upper outer flap 7a is provided with a pair of tongue-forming cutting lines 16 provided continuously to the third breakable line 13 and the ends of the pair of cutting lines 16. An easy-to-bend line 15 for forming a tongue piece is formed. In the box sheet, the third breakable line 13 has a straight line portion 13a extending in the width direction of the first upper outer flap 7a, and the pair of cutting pieces 16 for forming tongue pieces is based on the straight line portion 13a. As an end, it extends in a direction perpendicular to the straight line portion 13a and toward the distal end side of the first upper outer flap 7a, and an easy-to-bend line 15 for forming a tongue piece connects the distal ends of the pair of cutting lines 16. ing. In addition, the part between the cutting line 16 for a pair of tongue pieces formation of the 3rd easy break line 13 is cut | disconnected long so that the tongue piece 14 can be formed easily. Note that the second easy break line “overlaps with the first easy break line during assembly” means that the second easy break line and the first easy break line are completely coincided with each other when viewed in the vertical direction of the first side panel in the assembled state. In addition to the case, it includes a state where the second easy break line and the first easy break line are shifted by the thickness of the sheet as viewed in the vertical direction of the first side panel.

  In the assembled state, the box sheet separates a region surrounded by the first easy break line 11 and the third easy break line 13 (hereinafter also referred to as “first separation region P”), and further the second easy break line 12. And an area Y defined by the upper edge of the fifth side panel 6 (hereinafter, also referred to as “second separation area Q”) is formed to form an opening Y for taking out an article in the box as shown in FIG. can do.

  A procedure for forming the opening Y in the box will be described. First, the portion between the pair of tongue-forming cutting lines 16 of the third easy-to-break line 13 is broken, and the tongue piece 14 is bent inward along the easy-to-bend line 15. As shown in FIG. 3, the tongue piece 14 is formed between the first upper inner flap 8 a and the second upper inner flap 10 a in a plan view, and between notches 17 and 18, which will be described later. The other sheets are not laminated. Further, since the article accommodated in the box is normally held on the inner surface side of the first upper inner flap 8a and the second upper inner flap 10a, at least the sheet thickness is provided between the tongue piece 14 and the article. Voids are formed. Therefore, the box sheet is easy to bend the tongue piece 14 inside the box in an assembled state.

  Next, as shown in FIG. 4, a finger is put into the opening Z formed by bending the tongue piece 14, and the finger is put on the edge of the first separation region P. Then, with the finger placed on the edge of the first separation region P, the finger is pulled outward. Thereby, the 3rd easy break line 13 and the 1st easy break line 11 can be broken from the tongue piece 14 side. As a result, as shown in FIG. 5, the first separation region P can be easily separated from the box.

  Subsequently, the upper end portion of the second separation region Q exposed on the outer surface of the box is gripped and pulled outward. Thereby, the 2nd easy break line 12 can be easily fractured from the upper side. As a result, as shown in FIG. 6, an opening Y for taking out an article can be formed in the box by separating the second separation region Q from the box. In addition, in order that the said sheet | seat for boxes may make easy separation of the 2nd separation area | region Q, the both ends of the 2nd easy breakable line 12 may be cut | disconnected long.

  The box sheet has a convex shape in which both ends of the first easy-to-break line 11 are located at the boundary with the first upper outer flap 7a, and both ends of the first upper outer flap 7a are both ends of the first easy-to-break line 11. Are formed, and the breakable start tongue 14 adjacent to the breakable easy line 13 is formed, so that the tongue 14 is bent as described above. The first easy breakable line 11 and the third easy breakable line 13 can be easily and reliably made from the third easy breakable line 13 side by putting a finger in the opening Z formed by the Can be broken.

  The overall outline of the first easy break line 11 and the third easy break line 13 is a rectangular shape having a pair of first sides parallel to the connecting direction and a pair of second sides perpendicular to the first sides. Preferably there is. Thereby, the articles accommodated in the box body can be easily taken out from the opening Y. The first side formed on the first side panel 2 and the pair of second sides are preferably curved inwardly. More specifically, the first side formed on the first side panel 2, the pair of second sides, and the fifth side panel 6 formed on the first side and the second side overlap each other on the inside. It is preferable to be convexly curved. Accordingly, the buckling strength of the box body is reduced due to the bending of the first side panel 2 and the fifth side panel 6 while suppressing the unintended breakage of the first easy break line 11 to the third easy break line 13. It can be suppressed more accurately. In addition, it is preferable that the said 1st edge | side formed in the said 1st upper side outer flap 7a is curving so that the said sheet | seat for boxes may be linear form or may protrude outside. When the first side formed on the first upper outer flap 7a is curved inward, when the finger is pulled outward with the finger placed on the first separation region P, the first separation region P is There is a risk of tearing at the curved part.

  The first separation region P is preferably formed at the center in the left-right direction of the first side panel 2. The lower limit of the ratio of the average length in the left-right direction of the first separation region P to the length in the left-right direction of the first side panel 2 is preferably 0.50 and more preferably 0.65. On the other hand, the upper limit of the ratio is preferably 0.85, and more preferably 0.75. If the ratio is less than the lower limit, it may be difficult to easily remove the article from the opening Y. On the other hand, if the ratio exceeds the upper limit, the buckling strength of the box may not be sufficiently obtained with the opening Y formed.

  As a minimum of the occupation area rate of the 1st separation field P in the 1st side panel 2, 0.3 is preferred and 0.4 is more preferred. On the other hand, the upper limit of the occupied area ratio is preferably 0.7, and more preferably 0.6. If the occupation area ratio is less than the lower limit, it may be difficult to easily remove the article from the opening Y. On the contrary, if the occupation area ratio exceeds the upper limit, the buckling strength of the box may not be sufficiently obtained in a state where the opening Y is formed.

  The corners of the first easy break line 11 and the third easy break line 13 are preferably rounded. More specifically, it is preferable that the corners of the first easy break line 11 and the third easy break line and the corners of the second easy break line 12 overlapping the first easy break line are rounded. According to this configuration, the first easy break line 11 to the third easy break line 13 can be reliably broken, and the occurrence of breakage in portions other than the first easy break line 11 to the third easy break line 13 is suppressed. can do.

  Moreover, it is preferable that the corner | angular part of the 1st easy break line 11 thru | or the 3rd easy break line 13 is cut | disconnected continuously. In this way, the corners of the first easy break line 11 to the third easy break line 13 are continuously cut, so that the first easy break line 11 to the third easy break line 13 are obtained at these corners. It can suppress more reliably that parts other than are torn.

  The first upper inner flap 8a and the second upper inner flap 10a are preferably formed with notches 17 and 18 corresponding to the third easy break line 13. Specifically, as shown in FIG. 3, the first upper inner flap 8a and the second upper inner flap 10a are formed with notches 17 and 18 exposing the third easy-to-break line 13 on the inner surface of the box. It is preferable. Thus, by forming the notches 17 and 18 exposing the third easy-to-break line 13 on the inner surface of the box, the opening Y is blocked by the first upper inner flap 8a and the second upper inner flap 10a. Therefore, the article accommodated in the box can be easily taken out from the opening Y.

<Advantages>
Since the margin sheet 1 is attached to the outer surface on the other side in the connecting direction of the fourth side panel 5 at the time of assembly, the box sheet has a fifth continuous from the fourth side panel 5 to the other side in the connecting direction. The side panel 6 can be stacked inside the first side panel 2 during assembly. In addition, the box sheet is formed with the first easy break line 11 and the second easy break line 12 that overlap the first side panel 2 and the fifth side panel 6 at the time of assembly. By breaking the line 11 and the second easy-to-break line 12, an opening Y for taking out an article can be formed in the box. In the box sheet, since the first side panel 2 and the fifth side panel 6 overlap during assembly, the buckling strength decreases due to the first easy break line 11 and the second easy break line 12 in the assembled state, and It is possible to suppress a decrease in buckling strength after forming the opening Y for taking out the article. Therefore, the box sheet can obtain a sufficient buckling strength even when the first easy-to-break line 11 is provided on a length panel that is relatively easy to bend so that the area of the opening Y can be sufficiently secured. Can do.

[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 third easy break line does not need to be formed on the first upper outer flap, and may be formed on the first lower outer flap. In addition, the box sheet may be configured such that the third easy-to-break line is not formed on any of the first upper outer flap and the first lower outer flap. For example, the box sheet has a rectangular first easy break line formed on the first side panel, and the first easy break line is formed on the fifth side panel. It is good also as a structure which can form the opening for taking out articles | goods by breaking the 2nd easy-to-break line which overlaps.

  Even when the third easy break line is formed, the specific shape of the third easy break line is not particularly limited. Further, the box sheet may not have a break-starting tongue piece adjacent to the third easy break line even when the third easy break line is formed. Furthermore, even if it has the said tongue piece, this tongue piece does not necessarily need to be demarcated by a pair of cutting line and a fold easy line.

  In the box sheet, notches corresponding to the third easy break line are not formed in the first inner flap and the second inner flap overlapping the first outer flap in which the third easy break line is formed at the time of assembly. Also good. Further, the box sheet may be provided with an easy-to-break line for forming a notch instead of the notch.

  As described above, the box sheet of the present invention can form an opening for taking out an article in the side panel and can sufficiently increase the buckling strength of the box body. It is suitably used for display.
