Description

  The present invention relates to a wrap-around cardboard box.

  Conventionally, a corrugated cardboard box is used as a container for collectively storing a plurality of products from transportation to product display, or as a packaging container for selling heavy goods such as home appliances and potted plants. In particular, when a canned beverage, a detergent, or the like is accommodated, a wrap-around type cardboard box may be used.

  This wrap-around type cardboard box forms a square cylinder by a top plate, a bottom plate, and a pair of side plates connecting the top plate and the bottom plate, and opening surfaces at both ends of the square tube Is sealed with an outer flap extending from the top plate and the bottom plate and an inner flap extending from the side plate.

  In such a wrap-around type cardboard box, in order to form the rectangular tube body, for example, there is an adhesive margin portion that extends from the side edge of the top plate and bonds the top plate and the one side plate. Is provided. Therefore, when assembling this wrap-around type cardboard box, the above-mentioned outer flaps and inner flaps, and the glue margin and side plates are bonded using a hot-melt adhesive or the like. A cardboard box having strength will be formed.

  As a method of opening the wrap-around type cardboard box, there is a method of opening an outer flap portion sealed with an adhesive (see, for example, JP-A-2006-76588). Also, in a wrap-around type cardboard box, the bottom plate side can be used as it is as a product display tray by dividing the box into two parts, top and bottom (top plate side and bottom plate side). After being brought into the store as a box, the box is often divided into two parts, and the bottom plate side is displayed as it is as a display tray. As a method of dividing such a wrap-around type box into two, a method using a cut tape is generally used. For example, a cardboard is provided that is divided into two by providing a cut tape on the inner flap and the side plate and pulling out the cut tape. Boxes and the like have been developed (see JP 2006-96399 A).

  On the other hand, in the distribution industry that frequently uses cardboard boxes as packaging materials, high consideration is given to the environment, energy saving, and cost. For this reason, reduction of the weight of the corrugated cardboard box and the use of a small amount of adhesive or the like during assembly has been studied. Moreover, it is difficult to say that the opening means of the wrap-around type cardboard box is easy to open, and there is room for improvement.

JP 2006-76588 A JP 2006-96399 A

  The present invention has been made in view of these circumstances, and can wrap around a cardboard box that can be used for corrugated paper and adhesives during assembly and can be easily opened. The purpose is to provide.

The idea made to solve the above problems is
One side plate, bottom plate, other side plate and top plate connected in this order,
Two pairs of outer flaps respectively extending from the front and rear edges of the bottom plate and top plate;
A wrap-around type cardboard box formed of cardboard paper having two pairs of inner flaps extending from the front and rear edges of the one and other side plates,
The top plate and the one side plate are not connected,
The top plate and the pair of outer flaps extending from the top plate are separably formed.

  According to the corrugated cardboard box, the top plate and the one side plate are not connected to each other, so that the glue margin portion extending from the top plate and bonded to the side plate becomes unnecessary. Therefore, according to the corrugated cardboard box, the use amount of the corrugated paper is reduced by not providing the adhesive margin portion, and the adhesive amount to be adhered to the adhesive margin portion becomes unnecessary, so the usage amount of the adhesive is also reduced can do.

  Further, according to the cardboard box, the top plate and the one side plate are not connected to each other, and the top plate and the pair of outer flaps extending from the top plate are separably formed. Therefore, it can be easily opened by pulling up with the side edge of the top plate on the one side plate side. Furthermore, according to this cardboard box, even when the side surface portion (side plate and outer flap or the like) is hidden by another cardboard box or the like, it can be easily opened by having the top plate. In addition, according to the corrugated cardboard box, since no cut tape for facilitating opening is provided, the use of this cut tape can be reduced.

  The top plate and a pair of outer flaps extending from the top plate may be connected via a zippered cut line. According to the corrugated cardboard box, the top plate is processed along the processing line by being processed with a zipper-like cut line between the top plate and the pair of outer flaps extending from the top plate. Can be separated, making it easier to open.

  The top plate may have a ruled line formed in parallel with the side edge. According to the cardboard box, the top plate has such a ruled line, so that the top plate can be used by folding the top plate along the ruled line after the top plate is separated from the outer flap and opened. Therefore, according to the cardboard box, for example, when used as a product display tray, the outer surface of the top plate can be used as a display plate for product advertisements.

  Here, the “zipper-shaped cut line” refers to a cut formed by continuously forming a cut of a line shape or a curved shape, such as a “<” shape, a “L” shape, a “Y” shape, or a “T” shape. Say a stranded wire.

  As described above, according to the wrap-around type corrugated cardboard box of the present invention, it is possible to suppress the amount of corrugated paper, the amount of adhesive used during assembly, and the like, and to easily open the cardboard.

The perspective view which shows the cardboard box which concerns on one Embodiment of this invention The top view which shows the cardboard paper which forms the cardboard box of FIG. The perspective view which shows the middle of opening of the cardboard box of FIG. The perspective view which shows one usage method of the cardboard box of FIG.

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

  A cardboard box 1 in FIG. 1 is a wrap-around type cardboard box formed by assembling the cardboard paper 21 in FIG.

  The type of the corrugated paper 21 is not particularly limited, and for example, single-sided corrugated paper, double-sided corrugated paper, double-sided corrugated paper, and the like can be used. preferable.

  Further, as the flute type of the corrugated paper 21, A flute, B flute, C flute, AB flute, E flute and the like can be used, but from the viewpoint of reducing the thickness and weight and exhibiting sufficient pressure resistance. To B flute is preferably used. Conventionally, corrugated paper of strong A flute (thickness about 5 mm) is often used for packing heavy goods. However, by using corrugated paper of B flute (thickness of about 3 mm), the cardboard box 1 can be further reduced in weight and thickness, and the environmental load is reduced from the viewpoint of reducing the amount of paper used and transport energy. It is possible to reduce the transport efficiency and the inventory space.

  The corrugated cardboard 21 is connected in this order to one side plate 2, bottom plate 3, another side plate 4 and top plate 5, and two pairs extending from the front and rear edges of the bottom plate 3 and top plate 5. Outer flaps 6, 7, 8 and 9 (the outer flaps 6 and 7 and the outer flaps 8 and 9 are paired), the one side plate 2 and the other side plate 4. There are two pairs of inner flaps 10, 11, 12 and 13 (inner flaps 10 and 11 and inner flaps 12 and 13 are in pairs, respectively) extending from the front and rear edges. Note that the fine lines in the corrugated cardboard paper 21 in FIG. 2 indicate creases, and it is preferable that the creases are subjected to ruled line processing that facilitates folding.

  One side plate 2 and the other side plate 4 have the same shape and the same size, and have a strip shape. Since the width of the side plates 2 and 4 (the length in the left-right direction in FIG. 1) is the height of the corrugated cardboard box 1, the width is appropriately set according to the size of the product to be packed.

  The bottom plate 3 and the top plate 5 are also of the same shape and size and have a square shape. The sizes of the bottom plate 3 and the top plate 5 are also set as appropriate according to the size and number of products to be packed.

In addition, in the corrugated paper which forms a normal wraparound type corrugated cardboard box, in order to form a square cylindrical body from the top plate, the bottom plate and the pair of side plates, for example, the top plate in the corrugated cardboard 21 of FIG. and overlap portions are provided to extend to other face 4 of the 5 opposite from the side edge L _4.

  However, since the corrugated cardboard box 1 does not include such an adhesive margin, the amount of corrugated paper used is reduced, and an adhesive to be attached to the adhesive margin is not required during assembly. Therefore, the amount of adhesive used can also be reduced. Note that the absence of the margin part as described above is not only an effect of reducing the amount of the corrugated cardboard used for the area of the margin part, but also as shown as the shape of the corrugated cardboard 21 in FIG. Since the whole can be made into a substantially rectangular shape, unnecessary portions to be cut off from the rectangular cardboard paper can be minimized, in other words, the size of the cardboard paper can be reduced when obtaining the same type of cardboard box. be able to.

Top plate 5 has a border L ₁ is parallel to the side edge L ₃ and L _4. According to the cardboard box 1, by top plate 5 has a ruled line L _1, after opening by pulling top plate 5, it is possible to bend the top plate along the ruled line L ₁ for example on the inside (Fig. 4). Therefore, according to the cardboard box 1, when used as a product display tray, the outer surface side of the top plate 5 can be used as a display plate for product advertisements and the like.

The position of the ruled line L _1, is preferably between the center line M ₁ and the center line M ₂ below. Here centerline M ₁ is a ruled line L ₂ between the bottom plate 3 and the other face 4, the side edges L ₄ on the side not in contact with the other face 4 of the top plate 5 (the right side in FIG. 2) And the center line. The center line M ₂ is a center line of both side edges (L ₃ and L ₄ ) of the top plate 5.

When the ruled line L ₁ is closer to the side edge L ₃ than the center line M ₁ , when the top plate 5 is folded inward along the ruled line L ₁ , the side edge L ₄ of the top plate 5 becomes the bottom plate 3. And the top plate 5 cannot be bent flat, which is not preferable. On the other hand, it ruled L ₁ is when the center line M ₂ side edges L ₄ side, when bending the top plate 5 along the border L ₁ inside, the top plate 5 side edge L ₄ is another The upper edge of the side plate 4 is not reached. In this case, it is not preferable because the top plate 5 cannot be restrained and fixed by the product packaged in the cardboard box 1 or the sealed inner flaps 12 and 13 and the outer flaps 8 and 9.

The pair of outer flaps 8 and 9 extending from the top plate 5 of the top plate 5 Toko, are connected via a zipper-like score line L _5. As described above, the top plate 5 and the pair of outer flaps 8 and 9 extending from the top plate 5 are processed by the zipper-like cut line L ₅ , thereby A pair of outer flaps 8 and 9 extending from the top plate 5 are formed so as to be separable. Therefore, according to the corrugated cardboard box 1, the cardboard box 1 can be easily opened by pulling up with the vicinity of the side edge L ₄ of the top plate 5 on the side plate 2 side.

As a specific shape of the zipper-shaped cut line L _5, a first line formed in parallel with the fold line on the fold line between the top plate 5 and the outer flaps 8 and 9 extending from the top plate 5. linear segments, and extending from an opening side tip end of the first linear segment (side end edge L ₄ side) inward of the opening (the side edges L ₄ side) direction and top plate 5 of the It consists of the assembly of the cut line in which the cut line of the substantially "L" shape (the "L" shape which has an obtuse angle | corner bend angle) which consists of the 2nd linear line segment formed so ing. The zipper-like score lines L ₅ by a collection of such substantially "L" shaped, while maintaining the strength of the top plate 5 can be separated easily and cleanly in a desired direction.

  The two pairs of outer flaps 6, 7, 8, and 9 are all the same type and the same size, and have a belt-like shape. The width (length in the extending direction) of the outer corner flap is ½ of the width of the side plates 2 and 4, that is, the height of the cardboard box 1. By setting the width of the outer corner flap to ½ of the height of the cardboard box 1 in this way, the leading edges of the outer flaps come into contact with each other when assembled, and the strength against compression in the vertical direction can be increased. .

  Moreover, the left and right of the extending direction front end edge of each outer flap 6, 7, 8, and 9 are cut out in a band shape that is thrown in the left-right direction. Since each outer flap is provided with such a notch, it is possible to open the outer flap from the notched portion at the time of opening, so that the opening from the outer flap portion can be facilitated.

  The two pairs of inner flaps 10, 11, 12 and 13 are all the same type and the same size, and have a square shape. In the corrugated cardboard box 1, the extension direction lengths of the inner flaps 10, 11, 12 and 13 are the same as the extension direction lengths of the outer flaps. Thus, by making the extension direction length of the inner flap the same as the extension direction length of the outer flap, the cardboard paper 21 can be efficiently cut out from the rectangular cardboard base paper by minimizing excess portions. This reduces the amount of corrugated paper used and makes it more environmentally friendly.

  Next, a method for assembling and using the cardboard box 1 will be described.

Similar to a general wrap-around type cardboard box, first, products to be packaged on the bottom plate 3 of the cardboard paper 21 having the shape shown in FIG. Thereafter, the pair of side plates 2 and 4 are bent so as to rise along the product. Subsequently, the top plate 5 is bent so as to be parallel to the bottom plate 3 so as to cover the upper side of the product. In this state, the upper edge of one side plate 2 and the side edge L ₄ of the top plate 5 are in contact with each other.

  Subsequently, the two pairs of inner flaps 10, 11, 12, and 13 are folded inward so as to contact the product, and the two pairs of outer flaps 6, 7, 8, and 9 are folded inward so as to overlap each inner flap. . At this time, an adhesive such as a hot melt type is applied to a portion where each of the inner flaps and the outer flaps overlaps, and the inner flap and the outer flap are adhered by the adhesive, whereby the cardboard box 1 Will be sealed (see FIG. 1). The series of assembling operations of the cardboard box can also be performed using a general wrap-around type cardboard box assembling apparatus.

  Since the corrugated cardboard box 1 assembled in this way does not have an adhesive margin portion provided on a normal top plate or side plate as described above, the strength is slightly lower than that of a normal one. The use of the adhesive is limited to the portion where the inner flap and the outer flap overlap, and the amount of adhesive used can be reduced. Moreover, according to the corrugated cardboard box 1, the ease of opening is enhanced as will be described later.

When the cardboard box 1 is opened, as shown in FIG. 3, the top plate 5 is guided to the zipper-like cut line L ₅ by pulling up the side edge L ₄ of the top plate 5. Can be separated and opened. Thus, according to the cardboard box 1, in addition to the top plate 5 and the one side plate 2 being not connected, the top plate 5 and a pair of outer flaps 8 extending from the top plate 5 and 9 is separable, and can be easily opened by pulling up the side edge L ₄ of the top plate 5 on the side plate 2 side. Further, according to the cardboard box 1, even in a case where the side portions (side plates and outer flaps etc.) is hidden by another cardboard box or the like, the side edges L ₄ portions of top plate 5 positioned on the upper side In addition to being able to be opened easily by holding, for example, since a cut tape generally provided to facilitate opening is not provided, the use of this cut tape can also be reduced.

Moreover, the cardboard box 1, after the opening, as shown in FIG. 4, along the borders L ₁ provided in top plate 5, it is possible to bend the top plate 5 on the inside. The top plate 5 folded in this way is fixed to the product stored in the cardboard box 1 or the left and right inner surfaces (inner flaps 12 and 13) of the cardboard box 1 as shown in FIG. The corrugated cardboard box 1 in which the top panel 5 is bent in this way is used, for example, when the cardboard box 1 is used as a product display tray, the outer surface of the top panel 5 is used as a display board for product advertisements, etc. can do.

  The cardboard box of the present invention is not limited to the above embodiment. For example, the top plate and a pair of outer flaps extending from the top plate are perforated lines (line segments) instead of zipper-like cut lines. Or a half-cut line or the like. Even when these shapes of lines are provided, the top plate and the outer flap extending from the top plate can be separated, and the top plate can be easily opened.

  In addition, one or a plurality of cutouts may be provided in the side edge portion of the top plate contacting the top edge of one side plate or the top edge portion of one side plate contacting the top plate. By providing such a notch, when the top plate of the cardboard box is to be opened, the top plate can be grasped by pointing a finger or the like to the notch, which improves workability and ease of opening. Can be increased.

  As described above, according to the corrugated cardboard box of the present invention, it is possible to reduce the amount of corrugated cardboard and the amount of adhesive used during assembly, and it can be easily opened. It can be suitably used as a wrap-around cardboard box for packing beverage products, foods, detergents and the like.
