Description

The present invention relates to a box sheet.

In some cases, products are housed in cardboard boxes, stored and transported, and displayed as they are in stores. As a corrugated cardboard box intended for such display, for example, among the panels that make up the box, a part of the top plate with the widest area can be opened, and the product can be displayed in a visible state. (See JP-A-2013-151298).

In the cardboard box described in this publication, the length is the same from the leading edge of the top plate to the bending point in front of the fold line between the top plate and the front plate along both fold lines between the top plate and both outer side plates. A pair of easy-to-cut lines parallel to each other, and a mountain-shaped easy-to-cut line that bends and extends from the bending point in the direction of the intermediate part of the fold line between the top plate and the front plate, and both are connected to form a top part. A top surface opening portion is formed in the top surface plate by.

This top surface opening part is connected to the rear plate through the fold line between the top plate and the rear plate, and after opening, for example, by folding it in half, it is parallel to the rear plate, that is, in a direction perpendicular to the top plate. It is configured to function as a display board that stands upright.

A box sheet assembled into a box, comprising an outer flap and a pair of bottom inner flaps extending from lower edges of the first width panel and the second width panel, wherein the first length panel and the boundary line between the first width panel and the second width panel is formed by an easy-to-cut line, and the first lid outer flap is linearly parallel to the base edge thereof, and the second width panel 1 has a first cut portion that crosses the lid outer flap in the width direction, and the first bottom outer flap is in a straight line parallel to its base edge and crosses the first bottom outer flap in the width direction. It has a second cut.

The box body assembled from the box sheet can be opened by cutting off the entire first longitudinal panel, and can be displayed in a state where the product can be seen with the opened portion as the upper surface. At this time, since the entire first longitudinal panel is removed from the box, it is possible to prevent products that are difficult to take out. In addition, since the entire first longitudinal panel is removed from the box, it is easy to stack a plurality of boxes even in the unsealed state.

At least one of the first cut portion and the second cut portion extends from a cut line formed in the center and from both sides of the cut line to the side edges of the first lid outer flap and the first bottom outer flap, respectively. It is preferable to be configured by a pair of easy-to-cut lines. By configuring the cutting portion in this manner, the package can be easily opened from the cutting line formed in the center as a starting point.

In the assembled state, the tip edges of the first lid outer flap and the second lid outer flap are butted against each other, and a sealing tape is adhered to at least the outer surface of the first lid outer flap and the second lid outer flap. between the side edge of the sealing tape located on the first lid outer flap and the proximal edge of the first lid outer flap, It is provided at a position close to the side edge of the sealing tape, and in the assembled state, the tip edges of the first bottom outer flap and the second bottom outer flap are butted against each other, and at least the first bottom outer flap and A sealing tape is attached to the outer surface of the second bottom outer flap so that the box can be sealed, and the second cut portion is on the side of the sealing tape located on the first bottom outer flap. It may be provided at a position adjacent to the side edge of the sealing tape between the edge and the proximal edge of the first bottom outer flap. By configuring the first cut portion and the second cut portion in this way, it is possible to increase the area of the removed portion of the first lid outer flap and the first bottom outer flap. Products on the flap side and the first bottom outer flap side can be easily taken out. In addition, most of the portions of the first lid outer flap and the first bottom outer flap that remain in the box body are covered with the sealing tape, and are integrated with the second lid outer flap and the second bottom outer flap, respectively. A side wall is formed to facilitate supporting the product from the side.

Preferably, the first longitudinal panel has a straight folding line parallel to its upper edge and for folding the first longitudinal panel in two. By thus providing the fold-easy line on the first longitudinal panel, the separated portion including the entire first longitudinal panel separated at the time of display can be used as a display board.

"Inside" and "outside" refer to the inside and outside of the box, respectively.

[Details of the embodiment of the present invention]
BEST MODE FOR CARRYING OUT THE INVENTION A box sheet according to an embodiment of the present invention will be described below with reference to the drawings as appropriate.

The box sheet 1 shown in FIG. 1 is a box sheet that is assembled into a box body 2 of type A (mandarin orange box type) as shown in FIG. In FIG. 1, thick solid lines indicate cutting lines obtained by cutting the sheet, and thin solid lines indicate ruled lines formed by creasing the sheet.

The box sheet 1 is formed from one sheet material. As the sheet material, for example, a corrugated cardboard sheet, a plastic board, a cardboard, or the like can be used. Among them, a cardboard sheet is preferably used. In the following, a case where the box sheet 1 is made of a cardboard sheet will be described as an example, but it is not intended that the sheet material is limited to the cardboard sheet.

The corrugated cardboard sheet may be a so-called double flute in which a core is sandwiched between three liners instead of one in which both sides of a core are sandwiched between a pair of liners. A so-called single-sided cardboard having a liner attached only to one side of the core may be used.

From the viewpoint of strength, the lower limit of the thickness of the sheet material is preferably 3 mm. On the other hand, although the upper limit of the thickness of the sheet material is not particularly limited, 8 mm is preferable from the viewpoint of easiness of assembly to the box 2 .

The box sheet 1 includes a first width panel 11, a first length panel 12, a second width panel 13, and a second length panel 14, which are connected in this order in the left-right direction (x direction in FIG. 1). , a first lid outer flap 15 extending from the upper edge of the first longitudinal panel 12, a second lid outer flap 16 extending from the upper edge of the second longitudinal panel 14, and the first width panel 11. and a pair of inner lid flaps 17 extending from the upper edge of the second width panel 13, a first bottom outer flap 18 extending from the lower edge of the first longitudinal panel 12, and the second longitudinal panel 14. A second outer bottom flap 19 extending from the lower edge, a pair of inner bottom flaps 20 extending from the lower edges of the first width panel 11 and the second width panel 13, and an adhesive margin 21 are provided.

<Length panel and width panel>
The length panels (first length panel 12 and second length panel 14) and the width panels (first width panel 11 and second width panel 13) are generally rectangular. The first longitudinal panel 12 and the second longitudinal panel 14 have the same size, and the first width panel 11 and the second width panel 13 have the same size.

The vertical length of the length panel (length in the y direction in FIG. 1) is equal to the vertical length of the width panel. Further, the length of the length panel in the left-right direction (the length in the x direction in FIG. 1) is equal to or greater than the length of the width panel in the left-right direction.

The vertical length of the length panel and the width panel, the length of the length panel in the left and right direction, and the length of the width panel in the left and right direction are determined by the box body 2 assembled with the box sheet 1. It is appropriately determined so as to correspond to the size and number of items to be stored. Above all, it is preferable that the vertical length of the length panel is longer than the horizontal length of the width panel. In the box body 2 assembled with such a box sheet 1, when the second length panel 14 is used as the bottom surface for display, the height is the length of the two sides of the second length panel 14 that constitutes the bottom surface. Since it is shorter than any other length, it has excellent stability during display.

<Lid Outer Flap and Lid Inner Flap>
The lid outer flap (the first lid outer flap 15 and the second lid outer flap 16) and the lid inner flap 17 are substantially square-shaped, and as shown in FIG. A sealing tape X1 is attached to at least the outer surfaces of the first lid outer flap 15 and the second lid outer flap 16 by abutting the tip edges of the two lid outer flaps 16 against each other, thereby enabling sealing. Specifically, during assembly, a pair of lid outer flaps (first lid outer flap 15 and second lid outer flap 16) and a pair of lid inner flaps 17 are extended so that the lid inner flaps 17 are on the inside. Fold the length panel (first length panel 12 and second length panel 14) and width panel (first width panel 11 and second width panel 13) inward at right angles, and seal tape The lid portion 2a of the box 2 can be formed by attaching X1 to the outer surface.

The extension direction length of the first lid outer flap 15 and the second lid outer flap 16 (length in the y direction in FIG. 1) is, for example, 1/2 of the length of the width panel in the horizontal direction.

On the other hand, the length in the extending direction of the pair of inner lid flaps 17 is not particularly limited, but can be made equal to the lengths of the first outer lid flap 15 and the second outer lid flap 16 .

The lengths of the first lid outer flap 15, the second lid outer flap 16, and the pair of inner lid flaps 17 in the left-right direction (the length in the x direction in FIG. 1) are not particularly limited. It is preferable to make it equal to the length in the left-right direction of the side panel and the width side panel.

The tip corners of the pair of inner lid flaps 17 on the side of the first longitudinal panel 12 are preferably rounded as shown in FIG. By rounding the tip corners of the pair of inner lid flaps 17 on the side of the first longitudinal panel 12 in this way, it is possible to make it easier to take out the product on the side of the first outer lid flap 15. Even if the operator's hand hits it when taking it out, it does not cause discomfort (see FIG. 4).

<Outer bottom flap and inner bottom flap>
The bottom outer flaps (the first bottom outer flap 18 and the second bottom outer flap 19) and the bottom inner flap 20 are substantially rectangular, and in the assembled state, the tips of the first bottom outer flap 18 and the second bottom outer flap 19 A sealing tape X2 is adhered to at least the outer surfaces of the first bottom outer flap 18 and the second bottom outer flap 19 with the edges matched to each other so as to be sealed. The bottom part 2b of the box 2 is formed by this sealing. The sealing tape X2 may be separate from or integrated with the sealing tape X1 for sealing the lid portion 2a.

The tip corners of the pair of bottom inner flaps 20 on the side of the first length panel 12 are preferably rounded as shown in FIG. By rounding the tip corners of the pair of bottom inner flaps 20 on the side of the first length panel 12 in this way, it is possible to make it easier to take out the product on the side of the first outer bottom flap 18, and for example, to remove the product. Even if the operator's hand hits it when taking it out, it does not cause discomfort (see FIG. 4).

Since the first outer bottom flap 18 and the second outer bottom flap 19 and the pair of inner bottom flaps 20 can be configured similarly to the first outer lid flap 15 and the second outer lid flap 16 and the inner lid flap 17, other details are shown below. Description is omitted.

<Margin part>
The margin 21 is formed on one end side of a belt-shaped body composed of the first width panel 11, the first length panel 12, the second width panel 13, and the second length panel 14, which are connected in this order in the left-right direction. is provided in In the box sheet 1 of FIG. 1 , the paste allowance portion 21 is provided on the first width panel 11 . The paste margin portion 21 is configured to be able to abut on the other end of the strip. By attaching this contact portion to the other end of the strip, the strip can be made endless. Alternatively, the bonding may be replaced by wire bonding or the like.

Although the margin 21 can be rectangular, it is preferably trapezoidal. Specifically, it is preferable that the margin 21 has an isosceles trapezoidal shape in which a pair of side edges thereof inclines inward as the distance from the belt-like body increases. By forming the paste margin portion 21 into an isosceles trapezoidal shape in this way, when the box sheet 1 is assembled to the box body 2, the adhesion strength near the side edge of the paste margin portion 21 can be maintained and the paste can be applied. It is possible to prevent the side edge of the allowance portion 21 from interfering with the inner lid flap 17 and the inner bottom flap 20 .

<Separation part>
In the box sheet 1, as shown in FIG. 1, the boundaries between the first longitudinal panel 12, the first width panel 11 and the second width panel 13 are formed by easy cutting lines. In addition, the first lid outer flap 15 has a first cut portion 15a that is linear parallel to its base edge and crosses the first lid outer flap 15 in the width direction, and the first bottom outer flap 18 is , has a second cut 18a that is straight parallel to its proximal edge and transversely across the first outboard flap 18. As shown in FIG. The box body 2 formed by assembling the box sheet 1 can be obtained by cutting the boundary line, the first cut portion 15a, and the second cut portion 18a, which are composed of easy cutting lines, so that the first longitudinal panel 12 All of them and a part of the first lid outer flap 15 and the first bottom outer flap 18 (collectively referred to as a "separation portion 22") can be separated (see FIG. 4).

The first cut portion 15a and the second cut portion 18a are formed by cutting lines 15b and 18b formed in the center and from both sides of the cutting lines 15b and 18b toward the first lid outer flap 15 and the first bottom outer flap 18, respectively. A pair of easy-to-cut lines 15c, 18c extending to the edge may be formed. By configuring the cutting portion in this manner, the package can be easily opened from the cutting lines 15b and 18b formed in the center. In addition, in the box sheet 1, both the first cutting portion 15a and the second cutting portion 18a have the above-described configuration. It works.

The first cut portion 15a and the second cut portion 18a are provided so as to divide the first lid outer flap 15 and the first bottom outer flap 18 into two, respectively. Among them, as shown in FIG. 1 , the first cut portion 15a is located between the side edge of the sealing tape X1 located on the first lid outer flap 15 and the base edge of the first lid outer flap 15. A second cut portion 18a is provided at a position close to the side edge of the box tape X1, and the side edge of the sealing tape X2 located on the first bottom outer flap 18 and the base edge of the first bottom outer flap 18. It is preferable to be provided at a position between and close to the side edge of the sealing tape X2. By configuring the first cut portion 15a and the second cut portion 18a in this way, it is possible to increase the area of the removed portion of the first lid outer flap 15 and the first bottom outer flap 18, so that the first It is possible to make it easier to take out the products on the lid outer flap 15 side and the first bottom outer flap 18 side. In addition, most of the portions of the first lid outer flap 15 and the first bottom outer flap 18 remaining in the box body 2 are covered with the sealing tapes X1 and X2, and the second lid outer flap 16 and the second bottom outer flap The side walls are formed integrally with the flaps 19, so that the product can be easily supported from the side.

In the box sheet 1, the first longitudinal panel 12 has an easy folding line 12a which is straight and parallel to the upper edge thereof and for folding the first longitudinal panel 12 in two. By providing the easy-to-fold line 12a on the first longitudinal panel 12 in this manner, the cut-off portion 22 including the entire first longitudinal panel 12 separated at the time of display can be used as the display plate 2c (FIG. 5). reference).

The position of the easy-to-bend line 12a can be appropriately determined in consideration of the area of the display panel 2c, etc., but it is preferable to set it at the vertical center of the first length panel 12, for example. By locating the bending easy line 12a at the center of the first length panel 12 in the vertical direction, the entire display panel 2c is formed by overlapping two sheets, so that strength can be easily ensured.

The easy-to-fold line 12a can be composed of a single line, but from the viewpoint of ease of folding, as shown in FIG. preferably configured.

<How to assemble the box>
A box assembly method for assembling the box sheet 1 into the box body 2 includes, for example, a rectangular tubular portion assembly step, a bottom portion assembly step, and a lid portion assembly step.

(Square tubular part assembly process)
In the square tubular part assembling process, the first width panel 11, the first length panel 12, the second width panel 13, and the second length panel 14, which are connected in this order in the left-right direction, are assembled into a square tube shape.

Specifically, the procedure is as follows. First, of the four panels described above, the second longitudinal panel 14 located at one side edge is folded over to the inner surface side of the adjacent second width panel 13, and the first width panel located at the other side edge is folded. The panel 11 is folded over to the inner side of the adjacent first longitudinal panel 12 . Then, the inner surface of the first width panel 11 on the other side in the left-right direction (the side opposite to the connection side with the first length panel 12) is adhered to the adhesive margin portion 21 . Thereby, the first width panel 11, the first length panel 12, the second width panel 13 and the second length panel 14 are connected endlessly. The paste margin portion 21 can be adhered to the first width panel 11 using, for example, an adhesive, a stapler, or the like.

Next, the above-mentioned four panels connected in an endless manner are expanded into a square tube shape. As a result, the sides of the box 2 are assembled into a square cylinder.

(Bottom assembly process)
In the bottom assembly step, the bottom 2b of the box 2 is assembled by a pair of inner bottom flaps 20 and a pair of outer bottom flaps (first outer bottom flap 18 and second outer bottom flap 19).

Specifically, the procedure is as follows. First, the pair of bottom inner flaps 20 are folded inwardly of the rectangular cylindrical box 2 so as to be perpendicular to the width panels (the first width panel 11 and the second width panel 13). Next, the pair of bottom outer flaps are folded perpendicular to the longitudinal panels (first longitudinal panel 12 and second longitudinal panel 14) so as to contact the outer surfaces thereof. The first bottom outer flap 18 and the second bottom outer flap 19 are configured so that their tip edges can be butted against each other. 2b is formed.

(Lid assembly process)
In the lid assembly step, the lid 2a of the box 2 is assembled by a pair of inner lid flaps 17 and a pair of outer lid flaps (first outer flap 15 and second outer lid flap 16).

This step is performed after the product to be packed is accommodated in the space surrounded by the rectangular tubular portion. Since the method of forming the lid portion 2a is the same as that of the bottom portion assembly process, detailed description thereof will be omitted.

<Display method>
A display method for displaying products using a box body 2 formed by assembling the box sheet 1 will be described. The box 2 stores products in the vertical direction, that is, with the lid portion 2a as the upper surface, and is displayed in the horizontal direction, that is, with the first longitudinal panel 12 as the upper surface (the lid portion 2a is the side surface).

The display method includes a separating step and a display panel forming step.

(Separation process)
In the separating step, the separating portion 22 is separated by cutting the boundary line between the first longitudinal panel 12, the first width panel 11 and the second width panel 13, and the first cutting portion 15a and the second cutting portion 18a.

First, as shown in FIG. 3, the box body 2 is placed so that the first lid outer flap 15 is on the upper surface, and the cutting line 15b of the first cutting portion 15a is used as a starting point, and the easy cutting lines continuing on both sides are cut. 15c is cut, and a part of the first lid outer flap 15 is opened upward.

Next, as shown in FIG. 4, the box 2 is laid down so that the first longitudinal panel 12 faces upward, and the boundary line between the first width panel 11 and the second width panel 13 and the second cut portion are cut. 18a are cut in this order. Since a part of the first lid outer flap 15 is opened, this cutting can be easily performed with this as a starting point.

When all are cut, as shown in FIG. 4, a cutaway portion 22 consisting of the entire first length panel 12 and a portion of the first lid outer flap 15 and the first bottom outer flap 18 can be cut away. Although the case where cutting is started from the first cutting portion 15a has been described here, in the box sheet 1, cutting may be started from the second cutting portion 18a.

(Display board construction process)
In the display board forming process, the display board 2c is formed using the separated portion 22 separated in the separating process. This step is omitted when the display panel 2c is not used.

First, the cut-off portion 22 is folded in two along the easy folding line 12a formed on the first longitudinal panel 12 to form the display plate 2c.

As shown in FIGS. 5 and 6, the display plate 2c includes a side wall composed of a portion of the first lid outer flap 15 remaining on the box body 2 and the second lid outer flap 16, and a pair of inner lid flaps 17. It can be easily and stably fixed by inserting the easy-to-fold line 12a between the two with the upper side.

When stacking a plurality of boxes 2 , it is preferable to perform the above-described separation step for each box 2 and perform the display panel forming step only for the uppermost box 2 . The lower box body 2 does not have the display plate 2c, that is, it can be in a state where there is no projection on the top surface side, so stacking is easy. Moreover, the display board 2c can be used for the uppermost box 2. FIG.

In the box sheet 1, the display plate 2c can be configured by simply inserting it, so if you want to stack the boxes 2 on the upper level, remove the display plate 2c, stack the boxes 2, and then place the box 2 on the top. It is recommended to reinsert the display plate 2c into the .

<Advantages>
The box body 2 assembled by the box sheet 1 can be opened by cutting off the entire first longitudinal panel 12, and can be displayed in a state where the products can be seen with the opened part as the upper surface. At this time, since the entire first length panel 12 is removed from the box 2, it is possible to prevent products that are difficult to take out. In addition, since the entire first longitudinal panel 12 is removed from the box 2, it is easy to stack a plurality of boxes 2 even in an unsealed state.
