Since there is a clearance between a pair of outer flaps 15 whose tip parts 71 face mutually in each width surface 17, an opening 43 is formed in each width surface 17. In the ridge 51 parts between at least one of the bottom surface and the width surface and each of the top surface 11, the width surface and the length surface 12, there is formed a chamfered part 31 which consists of a folded part of the packing carton 1 folded so that the ridge part 51 is chamfered.

Description

  The present invention relates to a packing box and a packing body.

  Non-Patent Document 1 discloses that the outer flap of a cardboard packaging box is shortened.

“Efforts to standardize packaging materials through the carton project” (http://www.kirinholdings.co.jp/csr/partner/measure.html)

  Since the outer flap of the packaging box of Non-Patent Document 1 has a short outer flap, when the outer flap is closed, a certain amount of gap is formed between the outer flaps whose tip portions face each other. Therefore, when the inner flap and the outer flap are closed, an opening is formed on the width surface formed by joining the closed inner flap and outer flap. Since there is an opening in the width surface in this way, when an operator tries to carry a packaging box in a state where the product is stored manually, the worker thinks that the opening is a hand hole, for example. Try to lift and move the packing box with your fingers in the opening.

However, since the edge portion of the opening is only the thickness of the cardboard, the total weight of the packaging box containing the product is placed on the operator's hand only through the relatively thin edge portion of the cardboard, and depending on the weight of the product, the work A person may feel a heavy load on the hand, and there is a problem that workability is not good.
Therefore, an object of the present invention is to provide a packaging box and a packaging body that have good workability in manual transportation work.

  In order to solve the above-described problems, an embodiment of the present invention is formed by a packaging box body that is a box, a flap that is formed on a width surface or a length surface of the packaging box body, and that is joined to each other, and the flap. An opening portion of the packing box body, which is formed by providing a gap between the flaps provided on at least one of the width surface or the length surface, the tip portions facing each other; , Formed at a ridge portion between at least one of the bottom surface and the top surface of the packaging box body and the width surface or the length surface on which the opening is formed, so that the ridge portion is chamfered. And a chamfered portion that is a bent portion of the packing box body.

In this case, the opening may be formed on two width surfaces or length surfaces facing each other back to back.
Moreover, you may make it the notch part which applies a finger | toe when the hand is applied to the said chamfering part further formed in the front-end | tip part of the said flap extended from the said chamfering part.
At least a part of the tip portion of the flap on the bottom surface side or the top surface side constituting the width surface or the length surface has an uneven shape in which the edge shape is continuous in the length direction of the tip portion. You may make it.
Furthermore, the chamfered portion may have a surface whose color is different from that of the surrounding portion.

Another aspect of the present invention is a packing body including any one of the above packing boxes and a plurality of items to be packed packed in the packing box.
In this case, the packaged item may be food or beverage.

  According to the present invention, it is possible to provide a packaging box and a packaging body that have good workability in manual transportation work.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a packaging box 1 according to the present embodiment. The packaging box 1 includes a packaging box body 2 that is a substantially hexahedral box. The packaging box body 2 is a box made of paper such as cardboard paper.

  FIG. 2 is a developed view of the packaging box 1 according to the present embodiment as viewed from the bottom. FIG. 3 is a developed view of the packaging box 1 according to the present embodiment as viewed from above. That is, what is illustrated in FIG. 2 and FIG. 3 are the front surface and the back surface of the cardboard paper for packing box 19 with the packing box 1 in an unfolded state. In FIGS. 2 and 3, the outer shape and the ruled line 3 (hereinafter referred to as “ruled line” together with the horizontal ruled line (Score) and the vertical ruled line (Crease)) of the corrugated cardboard paper 19 for developing the packing box 1 in FIG. Is indicated by a solid line. As shown in FIG. 2, the surface of the cardboard paper 19 for a packing box is a top surface 11, a length surface 12, a bottom surface 13, a length surface 12, and a joint 14 in order from the right, and a ruled line between them. 3 is formed. Outer flaps 15 are provided at both ends in the longitudinal direction of the corrugated cardboard constituting the top surface 11 and the bottom surface 13. In addition, inner flaps 16 are provided at both ends in the longitudinal direction of the corrugated cardboard constituting each length surface 12. FIG. 3 shows a developed view of the back surface of the cardboard paper for packaging box 19 shown in FIG. Reference numeral 21 corresponds to the rear surface of the top surface 11, reference numeral 22 corresponds to the rear surface of the length surface 12, and reference numeral 23 corresponds to the rear surface of the bottom surface 13.

  A chamfered portion 31 is provided between the top surface 11 and the outer flap 15 and between the bottom surface 13 and the outer flap 15 in the cardboard paper 19 for the packaging box. Further, a chamfered portion 32 is provided between the top surface 11 and the length surface 12 and between the bottom surface 13 and the length surface 12 in the corrugated cardboard for packaging box 19. A ruled line 3 is formed between the chamfered portions 31 and 32 and the top surface 11, the length surface 12, the bottom surface 13, and the outer flap 15. Details of the chamfered portions 31 and 32 will be described later.

  The unpacked packaging box 1 (packaging cardboard 19) having the above-described configuration has a length between the top surface 11 and the length surface 12 such that the bottom surface shown in FIG. Each ruled line 3 is bent between the surface 12 and the bottom surface 13 and between the length surface 12 and the joint 14. At this time, the ruled lines 3 around the chamfered portion 31 are also bent. And the edge part side part 33 (refer FIG. 3) of the transversal direction of the top | upper surface 11 and the joining margin 14 are joined with an adhesive agent etc. (refer FIG. 13 mentioned later). Thereafter, the inner flap 16 and then the outer flap 15 are each folded inward along the ruled line 3. At this time, the packaging box corrugated cardboard 19 is also bent at each ruled line 3 around the chamfered portion 32. Then, the inner flap 16 and the outer flap 15 are joined with an adhesive or the like so that the inner flap 16 is on the inner side and the outer flap 15 is on the outer side.

  Thus, the packaging box 1 as shown in FIG. 1 is completed by assembling the packaging box cardboard 19 in the unfolded state shown in FIGS. At this time, two surfaces formed by joining the inner flap 16 and the outer flap 15 become the width surface 17 respectively. Needless to say, all the inner flaps 16 and the outer flaps 15 of the both width surfaces 17 are joined after the products to be packed in the packing box 1 are stored in the packing box 1.

  FIG. 4 is a right side view of the packaging box 1 according to the present embodiment. Since the left side view of the packaging box 1 is the same as FIG. 4, the left side view is omitted. As described above, the width surface 17 includes the inner flap 16 and the outer flap 15 that are joined to each other. As is well known, the pair of inner flaps 16 bent inward are configured to be short so that a gap is formed between their tip portions. In the present embodiment, the pair of outer flaps 15 bent inward are also configured to be short so that a relatively large gap is formed between the tip portions 71. Therefore, in a state where the inner flap 16 and the outer flap 15 are joined, a relatively large opening 43 that communicates with the inside of the packaging box 1 is formed in the center portion of the width surface 17.

  By the way, the reason why the outer flap 15 is made short and the opening 43 is formed in the width surface 17 is to save the corrugated cardboard constituting the packaging box 1. That is, the packaging box cardboard 19 in the unfolded state shown in FIGS. 2 and 3 is manufactured by cutting out from a corrugated cardboard wound in a roll shape. That is, in this example, the longitudinal direction of the packaging box cardboard 19 in the unfolded state of FIGS. 2 and 3 is the width direction of the roll-shaped cardboard, and the packaging box corrugated cardboard in the width direction of the roll-shaped cardboard. For example, the packaging box corrugated paper 19 is cut out so that two 19 are arranged. In this case, if the outer flap 15 is made long so that the front end portions 71 of the pair of outer flaps 15 bent inward are almost in contact with each other, and the opening 43 is not formed in the width surface 17, the outer flap 15 is The length of the corrugated cardboard for packaging box 19 in the unfolded state shown in FIGS. 2 and 3 is also increased in the short direction. Therefore, when trying to cut the packaging box corrugated cardboard 19 from the corrugated cardboard wound in a roll shape one after another, the shorter the outer flap 15 as in the present embodiment, the same number of sheets as compared with the case where the outer flap 15 is long The length of the roll-shaped cardboard paper required for cutting out the packaging cardboard paper 19 is shortened (in the example of FIGS. 2 and 3, the outer flap 15 is substantially equal in length to the inner flap 16). . Therefore, according to the packaging box 1 of the present embodiment, the cardboard paper required for the production of the packaging box 1 can be saved, so that the packaging box 1 can be reduced in weight, and further, the packaging box 1 can be discarded by incineration or the like. The environmental load can be reduced.

However, since the opening portions 43 are provided in the both width surfaces 17 as described above, when the worker intends to carry the packaging box 1 in a state in which the product is stored, the worker, for example, The part 43 is assumed to be a handle hole, and a finger is put into the opening 43 to lift and move the packing box 1.
However, since the edge portion of the opening 43 has only the thickness of the corrugated paper, the entire weight of the packaging box 1 containing the product is placed on the operator's hand only through the relatively thin edge portion of the corrugated paper, and the weight of the product Depending on the situation, the worker may feel a heavy load on the hand, and there is a problem that workability is not good.

  In this case, avoid placing the hand on the opening 43 and transporting the packaging box 1 and put your finger under the bottom surface 13 or under the top surface 11 (if the packaging box 1 is upside down). Even when trying to lift, there is a gap between the bottom surface 13 (or top surface 11) placed on the floor surface or other packaging box 1 or the like and the floor surface or other packaging box 1 There is a problem that the finger is not easily put under the bottom surface 13 (top surface 11) and the workability is not good.

  Further, as in the present embodiment, when the opening 43 exists in the width surface 17, the product is exposed from the opening 43. Therefore, in the process of storing the product in the packing box 1 and then carrying it out from the factory, the packing box 1 in which the product is stored is transported by the automatically controlled transport mechanism in the factory. There is also a problem that the products in 1 are easily scratched or dented.

Therefore, in order to solve these problems, in the packaging box 1 of the present embodiment, as shown in FIG. 4, the top surface 11 and the bottom surface 13, and the length surface 12, which are located above and below the opening 43, respectively. A chamfered portion 31 is formed on the ridge 51 between the two, except for both ends in the length direction of the ridge 51. The chamfered portion 31 is a portion that is formed by being bent at the ruled lines 3 around the chamfered portion 31 and has an outer surface shape like a chamfered ridge 51. That is, the outer surface of the chamfered portion 31 is a surface 52 elongated in the length direction of the ridge 51 at the ridge 51, and gradually tapers from both ends of the surface 52 toward both ends of the ridge 51. It is composed of two substantially triangular faces 53 that are inclined upwardly toward both ends of the ridge 51.
By forming such a chamfered portion 31, the surface direction of the surface 52 of the chamfered portion 31 is inclined with respect to the surface directions of the top surface 11, the width surface 17, and the bottom surface 13 (passes the chamfered portion 31). The longitudinal cross-sectional shape of the packaging box 1 is as shown in FIG.

  Thus, the chamfered portion 31 is formed at the ridge 51 portion between the top surface 11 and the bottom surface 13 and the length surface 12 positioned above and below the opening 43. Therefore, compared with the case where the ridge 51 is not chamfered by the chamfered portion 31, the operator can easily insert his / her fingers between the packaging box 1 and the floor or between the stacked packaging boxes 1. Therefore, the workability of the carrying work of the packaging box 1 can be improved.

  Moreover, FIG. 5 cut | disconnected longitudinally the lower half of the packaging box 1 of this embodiment of the state which packed the goods 101 like a can drink in the longitudinal direction line (BB line of FIG. 11 mentioned later). It is a longitudinal cross-sectional view. FIG. 16 is a longitudinal sectional view in which the lower half of the packaging box 201 as a comparative example with respect to the packaging box 1 of the present embodiment is cut longitudinally along a longitudinal line thereof. In FIG. 16, the packaging box 201 as a comparative example is not provided with the chamfered portion 31 as long as it is shown in the same figure, and the corrugated paper constituting the bottom surface 13 and the outer flap 15 are directly connected via the ruled line 3. Since it is the same as that of the structure of the packaging box 1 except being described, detailed description is abbreviate | omitted.

  5 and 16, in this example, the product 101 is illustrated as an example of a canned beverage. In the packaging box 1 of the present embodiment in FIG. 5, the clearance (reference a) between the product 101 and the outer flap 15 is the clearance between the product 101 and the outer flap 15 in the packaging box 201 of the comparative example in FIG. 15. It becomes larger than (reference symbol b). This is because, for example, the packaging box 1 of the present embodiment is provided with the chamfered portion 31, so that the outer flap 15 is formed from the chamfered portion 31 protruding outward from the corrugated cardboard constituting the bottom surface 13 obliquely upward. By extending. The other is that the ruled line 3 between the corrugated cardboard and the outer flap 15 constituting the bottom surface 13 and the chamfered portion 31 is bent slightly to form an obtuse angle with respect to the ruled line 3 as shown in FIG. This is because the outer flap 15 tends to swell outward due to the restoring force of the corrugated paper because no strong folding line is attached. The same applies to the chamfered portion 31 protruding outward from the corrugated cardboard forming the top surface 11 obliquely downward and the outer flap 15 beyond the chamfered portion 31.

In addition, as shown in FIG. 5, when the product 101 is a canned beverage, generally, the can of the canned beverage is inclined between the cylindrical side surface 102 and the bottom surface 103 with respect to the side surface 102 and the bottom surface 103. An inclined surface 104 inclined in the direction is formed.
Therefore, in the product 101 located closest to the width surface 17 side or the length surface 12 side in the packaging box 1, the chamfered portions 31 and 32 on the bottom surface 13 side of the packaging box 1 have an inner shape of the product 101. The shape follows the inclined surface 104. Therefore, by providing the chamfered portions 31 and 32, the chamfered portions 31 and 32 and the inclined surface 104 come into close contact with each other, so that the holding force of the product 101 in the packaging box 1 increases.
As a result, when an external impact is applied to the packing body 201 (see FIG. 15) in which a plurality of products 101 are packed in the packing box 1 due to transportation, dropping, or the like, the cans of the products 101 in the packing box 1 can be obtained. It is possible to prevent the products 101 from being scratched or dented from colliding with each other.

Thus, since the clearance between the product 101 and the outer flap 15 is increased, the packaging box 1 of the present embodiment has a packaging box in the process of storing the product 101 in the packaging box 1 and then carrying it out from the factory. Scratches and dents are less likely to be attached to the product in 1.
In this case, as a means for sufficiently taking the clearance (symbol a), the longitudinal length of the corrugated cardboard constituting the top surface 11 and the bottom surface 13 is appropriate for the product 101 to be packed. It is also possible to make it longer.

However, increasing the length in the longitudinal direction of the corrugated cardboard constituting the top surface 11 and the bottom surface 13 means that the length in the short direction of the corrugated cardboard for packaging box 19 shown in FIGS. means. As described above, this is necessary for manufacturing the same number of cardboard papers 19 for the packaging box when the packaging box 1 is manufactured by cutting the cardboard papers 19 for the packaging box one after another from the roll-shaped cardboard paper. This leads to an increase in the length of the roll-shaped cardboard. Therefore, as described above, there is a problem that the significance of shortening the outer flap 15 to reduce the cardboard is reduced. Further, it is impossible to adjust the dimensions of the corrugated cardboard 19 for the packaging box while ignoring the dimensions of the product that is stored inside.
Thus, in order to save the cardboard and reduce the weight of the packaging box 1 and the environmental load, the chamfered portion 31 is formed in the packaging box 1 so that a sufficient clearance (symbol a) can be secured. Is appropriate.

Further, as shown in FIG. 4, the end portion 71 of the outer flap 15 connected to the chamfered portion 31 on the bottom surface 13 side that forms the width surface 17, the portion that becomes the edge of the opening 43 is Put a finger (usually the thumb) that is open when a hand (usually four fingers from the index finger to the little finger) is placed on the chamfer 31 formed on the ridge 51 between the bottom surface 13 and the width surface 17. A notch 72 is formed. In this example, the cutout portion 72 is a concave portion formed by cutting out the front end portion 71 of the outer flap 15 so that the edge shape is substantially semicircular, and the chamfer on the bottom surface 13 side when carrying the packaging box 1. It is formed at a position where the operator's thumb will be applied when the operator puts his hand on the portion 31. In this example, considering both the case where the chamfered portion 31 is put with the right hand and the case where the chamfered portion 31 is put with the left hand, the notch portions 72 are provided at positions where the thumb will be applied in each case. That is, the notches 72 are provided at two locations on the tip 71 of the single outer flap 15.
FIG. 6 is a perspective view showing an operation of carrying the packaging box 1 of the present embodiment by placing a hand on the chamfered portion 31. Reference numeral 301 is an operator's hand. The operator can carry the packaging box 1 by placing four fingers 303 other than the thumb 302 on the chamfer 31 and the thumb 302 on the notch 72.

Therefore, by forming the notch 72 in the packaging box 1, the operator can see that the packaging box 1 carries the four fingers 303 over the chamfer 31 and the thumb 302 over the notch 72. To make it easier to understand. Therefore, it is possible to urge the operator to carry the packing box 1 by placing a hand on the chamfer 31. That is, it is possible to urge the user to put his / her finger into the opening 43 and not touch the tip of the upper outer flap 15.
In consideration of the case where the packing box 1 is carried upside down, a notch portion 72 similar to the above is also provided at the front end portion 71 of the outer flap 15 connected to the chamfered portion 31 on the top surface 11 side. Also good. The size of the notch 72 is preferably about 1 to 3 cm in width and about 0.2 to 1 and 5 cm in depth. That is, the size of a person's finger varies from person to person, and it is considered that the size is appropriate from the viewpoint of being caught on the finger and being easily removed from the notch 72.

Further, as shown in FIG. 4, a concave-convex shape 81 is formed on the edge 71 of the outer flap 15 on the top surface 11 side and the bottom surface 13 side constituting the width surface 17 at the edge of the opening 43. Is formed. In this example, three concave and convex shapes 81 are provided at the tip 71 of the outer flap 15 on the top surface 11 side, and one at the tip 71 of the outer flap 15 on the bottom surface 13 side. Of course, the number of the uneven shapes 81 is not limited to this.
FIG. 7 is an enlarged view of the concavo-convex shape 81 of the packaging box 1 of the present embodiment. In this example, the edge shape of the concavo-convex shape 81 forms a continuous ridge-shaped concavo-convex shape in the length direction of the tip portion 71. Although the role will be described later, various shapes other than the mountain shape can be selected as the edge shape of the concavo-convex shape 81. However, a mountain shape or a wave shape that is not sharp when the finger touches the tip of the concavo-convex shape 81 is desirable. Moreover, as for the size of the uneven | corrugated shape 81, it is desirable that the length of a single unevenness | corrugation shall be about 0.5-1 cm and the depth is about 0.1-0.5 cm.

FIG. 8 shows an operation of carrying the packing box 1 by placing a hand on the edge of the opening 43 (an example of a bad case). That is, the portion that becomes the edge of the opening 43 at the front end portion 71 of the outer flap 15 on the top surface 11 side and the bottom surface 13 side constituting the width surface 17 carries the packaging box 1 by placing the hand on the opening 43. In this case, it is a part directly hit by the worker's hand 301.
As described above, the packaging box 1 according to the present embodiment has a configuration intended to carry the chamfered portion 31 by hand as shown in FIG. Still, an operator who does not care about the presence of the chamfered portion 31 of the packaging box 1 and thinks that the opening 43 is a handle hole and tries to carry the packaging box 1 by placing a hand on the edge of the opening 43. It is also possible to appear.

  Therefore, if the concave / convex shape 81 is provided at the distal end portion 71 of the outer flap 15, the concave / convex shape 81 is a continuous concave / convex shape when cutting the corrugated cardboard paper 19 for a packing box from a roll-shaped corrugated cardboard by a processing device. For this reason, the corrugated cardboard of the concave and convex shape 81 portion becomes soft and the sharpness of the tip is lost. Therefore, even if the edge portion of the opening 43 is put on the hand and the packaging box 1 containing the product is lifted, the operator does not feel a heavy load on the hand 301 and the workability is improved.

  FIG. 9 is a front view of the packaging box 1 according to the present embodiment. FIG. 10 is a rear view of the packaging box 1 according to the present embodiment. A chamfered portion 32 is provided in each of the ridge 51 portion between the top surface 11 and the length surface 12 and the ridge 51 portion between the bottom surface 13 and the length surface 12. The chamfered portion 32 is formed in a central portion excluding both end portions of the ridge 51 in the length direction of the length surface 12. The chamfered portion 32 is a portion that is formed by being bent along the ruled lines 3 around the chamfered portion 32 and has an outer surface shape like a chamfered ridge 51. That is, the outer surface of the chamfered portion 31 is a surface 56 elongated in the length direction of the ridge 51 at the ridge 51, and gradually tapers from both ends of the surface 56 toward both ends of the ridge 51, and both ends of the surface 56. It consists of two triangular surfaces 57 that are inclined upward from the ridge 51 toward both ends of the ridge 51. The elongated surface 56 of the chamfered portion 32 is shorter than the elongated surface 52 of the chamfered portion 31.

By forming such a chamfered portion 32, the surface direction of the outer surface of the chamfered portion 32 is inclined with respect to the surface directions of the top surface 11, the length surface 12, and the bottom surface 13 (passes the chamfered portion 32). The vertical cross-sectional shape of the packaging box 1 is as shown in FIG.
In this way, the chamfered portion 32 is formed at the ridge 51 portion between the top surface 11 and the bottom surface 13 and the length surface 12. Therefore, compared to the case where the ridge 51 is not chamfered by the chamfered portion 32, the operator can easily insert his / her fingers, so that the workability of the carrying work of the packaging box 1 can be improved.

  In addition, when the operator tries to carry the packaging box 1 by placing a hand on the chamfer 31 provided on the upper side or the lower side of the width surface 17, the top surface 11 (when the packaging box 1 is turned upside down) The portion of the ridge 51 between the bottom surface 13) and the length surface 12 tends to hit the front surface of the operator's body. However, since the packaging box 1 has the chamfered chamfered portion 32 at the ridge 51, the contact is soft and easy to carry, so the workability of the carrying work can be improved.

  FIG. 11 is a plan view of the packaging box 1 according to the present embodiment. FIG. 12 is a bottom view of the packaging box 1 according to the present embodiment. 13 is a cross-sectional view taken along line AA in FIG. 14 is a cross-sectional view taken along line BB in FIG. A chamfer 32 is provided between the top surface 11 and bottom surface 13 of the packaging box 1 and the length surface 12, and a chamfer is provided between the top surface 11 and bottom surface 13 of the packaging box 1 and the width surface 17. A part 31 is provided. Therefore, chamfered portions 31 and 32 to be put on are provided for both the width surface 17 side and the length surface 12 side. Moreover, even if the top and bottom of the packaging box 1 is reversed, there are chamfered portions 31 and 32 to be handled. Therefore, the workability of the carrying work of the packing box 1 can be improved.

Further, the chamfered portions 31 and 32 have a color different from that of at least the peripheral portions of the chamfered portions 31 and 32 among the top surface 11, the bottom surface 13, the width surface 17, and the length surface 12. As an example, the chamfered portions 31 and 32 are based on blue and the surroundings are based on yellow.
Thus, by making the surface of the chamfered portions 31 and 32 different from the surrounding color, the chamfered portions 31 and 32 are made conspicuous, and the position to be put on to hold the packaging box 1 is the chamfered portion 31, 32. If it is 32, it is possible to make the operator easily aware.

  FIG. 15 is a perspective view of a packing body 201 formed by packing a plurality of products 101 as packed items in the packing box 1 described above. In the above-described example, an example in which the product 101 as a packaged item is a can beverage has been shown, but the packaged product packed in the package 201 is not limited to this, and various items such as food and beverages can be used. Product. More specifically, the product 101 to be packed can be, for example, a beverage, food, or the like contained in a container, such as a can beverage, a plastic bottle beverage, or a paper pack beverage.

In addition, the present invention is not limited to the above-described embodiment, and includes various modifications. For example, the above-described embodiment has been described in detail for easy understanding of the present invention, and is not necessarily limited to one having all the configurations described.
For example, in the above example, the width surface 17 is formed by the inner flap 16 and the outer flap 15, but the length surface 12 may be formed by the inner flap 16 and the outer flap 15.

  Moreover, the opening 43 does not need to be formed in all the width surfaces 17 (or length surfaces 12) provided with the inner flap 16 and the outer flap 15, but the width surface provided with the inner flap 16 and the outer flap 15. 17 (or the length surface 12) may include one in which the lengths of the inner flap 16 and the outer flap 15 are long and the opening 43 is not formed. Of course, as described above, it is possible to form the openings 43 in any of the pair of width surfaces 17 (or the length surfaces 12) facing each other back to back in the packaging box 1. It is desirable from the viewpoint of saving.

Moreover, in the above-mentioned example, the chamfered portions 31 and 32 are formed in the center portion in the length direction of each ridge 51 between the top surface 11 and the bottom surface 13 and the width surface 17 or the length surface 12. However, the chamfered portions 31 and 32 may be formed on substantially the entire length of each ridge 51.
That is, the position of the handle when the packaging box 1 is held varies depending on the operator, so that if the chamfered portions 31 and 32 are formed almost entirely in the length direction of each ridge 51, the number of the handles increases. It is possible to cope with differences in the handles of workers.

  Further, the packaging box 1 of the above embodiment has a configuration in which the opening 43 is formed in the width surface 17 by shortening the outer flap 15, and the chamfered portion 31 and the uneven shape 81 are provided. However, the present invention is not limited to this, and the concavo-convex shape 81 may be formed in the packaging box 1 having the opening 43 without forming the chamfered portion 31.

  That is, the inner and outer flaps 16 and 15 (flaps) joined to each other, which form the packing box main body 2 that is a box, the width surface 17 or the length surface 12 of the packing box main body 2, and the width surfaces 17 respectively. Or the packaging box currently formed in each width surface 17 or the length surface 12 by having a space | interval between a pair of outer flaps 15 (flap) which the front-end | tip part 71 mutually faces in the length surface 12, respectively. At least a portion of the distal end portion 71 of the outer flap 15 (flap) on the bottom surface 13 side or the top surface 11 side that forms the width surface 17. It is good also as the packaging box 1 which has comprised the uneven | corrugated shape 81 continuous in the length direction of the part 71. FIG. Moreover, it is good also as a packing body provided with the said packing box and to-be-packaged goods, such as several goods 101 packed in this packing box.
