Moreover, it does not lead to an increase in cost.

  Hereinafter, an example of a specific embodiment of the packaging box of the present invention will be described with reference to FIGS.

  FIG. 1 shows an example of a developed drawing of the packaging box 1 of the present invention, and the surface appearing in the drawing corresponds to the surface of the box.

  2 to 4 show an example of how to assemble the packaging box of the present invention in order to understand the structure of the packaging box of the present invention, and automatically unpack the developed box original paper shown in FIG. It is the schematic perspective view which showed typically an example of the condition assembled sequentially using an apparatus. 2A is an inner surface side of the box original paper, and corresponds to a state in which the unfolded box original paper shown in FIG. 1 is turned upside down.

FIG. 5 is an enlarged view of a corner cut portion for explaining the main part of the present invention.
FIG. 6 is a view of the bottom of the present invention.

  The form of the packaging box 1 of the present invention can be understood from the developed view shown in FIG. 1 and the schematic assembly completion view of FIG. That is, first, for example, a container product (can product such as canned beer) is formed by a belt-shaped body portion formed by connecting a plurality of (four in the present embodiment) plate bodies 11, 21, 15, 25. After the group) is stored so as to wrap, the band-shaped body portion is integrally fixed to the tube shape with the adhesive margin piece 9 to form the cylindrical body portion.

  Thereafter, four fold connecting side pieces 38 (substantially rectangular shapes) are folded inward from the fold lines 61, 65, 81, 85 shown in FIG. 1, and four inner flaps are formed from the crease lines 62, 66, 82, 86. 31, 31, 35, 35 are folded inward.

  Next, gluing is performed at predetermined positions on the outer surfaces of the four folded inner flaps 31, 31, 35, 35.

  Next, the four outer flaps 41, 41, 45, 45 are folded from the crease lines 71, 75, 91, 95 toward the gluing surface, and the packaging box 1 is completed. This state corresponds to a so-called shipping box.

  In the present invention, the assembly procedure of the packaging box is an example for specifying the form of the box, and is not limited to the above-described procedure.

  The packaging box in the present invention is formed by connecting a pair of opposing side plates 11 and 15 on the side constituting the body portion of the upper surface plate 25, and at both ends on the opening side of the upper surface plate 25. Outer flaps 45, 45 on the upper surface side are connected to each other.

  Similarly, the above-described pair of side plates 11 and 15 are formed on the side of the bottom plate 21 that constitutes the body portion, and both end portions on the opening side of the bottom plate 21 are externally attached to the bottom side. Flaps 41 are formed.

Further, inner side flaps 31, 31 are connected to both end portions on the opening side of the side plate 11 via bent connecting side pieces 38, respectively, and an integrated side portion 30 is constituted by these.

  Similarly, inner flaps 35 and 35 are connected to both end portions on the opening side of the side plate 15 via bent connection side pieces 38, respectively, and an integrated side surface 30 is constituted by these.

  In the present invention, the formation of the bent connection side piece 38 forms a form in which the corners of the body part to which the inner flap is connected are cut off (corresponding to the symbol H in FIG. 1). That is, a notch corner (corner cut) is provided. Therefore, the planar shape seen from the upper surface plate 25 in the present embodiment is a modified octagon in which a corner portion of the box is cut off. In the present invention, the deformed octagon as shown in the figure is the most preferred form, but a predetermined number of additional corners are additionally formed on the bent connecting side piece 38, thereby forming a deformed dodecagon, a deformed hexagon, and a deformed octagon. , ……. That is, the packaging box in the present invention is in the form of an upper surface 4N square (N represents an integer of 2 or more, preferably N = 2), and for this form, the location where the inner flap is connected to the body part. In FIG. 2, the bent connecting side piece 38 is interposed, and the corner of the body part to which the inner flap is connected is cut off. The 4N square shape is considered to be unnecessary because the space at the corner (corner) is a so-called dead space, and further to improve handling and to improve visual design.

Such a packaging box of the present invention has a pair of tear start pieces 12, 13, 16, 17 formed in advance on the side plates 11, 15 of the packaging box when, for example, displaying the contents of the container product at the store. Are pulled from the center of the side plates 11 and 15 toward both ends, thereby removing the tear strips 4 and 5 connected to the tear start pieces 11, 13, 16 and 17. After each part is cut and the upper lid is removed, the remaining lower box remaining in the lower part is used as a paper tray for placing the product as it is. Such a so-called zipper function is generally formed conventionally, but the production of the zipper may be omitted if necessary.
Hereinafter, an example of assembly (automatic assembly / packing) of the packaging box of the present invention will be described over time based on FIGS.

The plate-like body of the packaging box in the unfolded state as shown in FIG. 2 (a) is folded so that the side plates 11 and 15 are raised as shown in FIG. 2 (b). At this time, the bent connecting side piece 38 and the inner flap 35, and the bent connecting side piece 38 and the inner flap 31 positioned on one side of the conveyor (located on the front side of the drawing) are sequentially shown in FIG. The first cam roller 100 that rotates in this manner is bent along the crease line.
Then, after being bent, the bent form is maintained by the conveyor guide 200 installed on the downstream side of the first cam roller 100 and is further conveyed downstream in this state. When the box being assembled is transported to the can supply position, a group of can beer products are supplied (CAN FEED in the figure) as shown in FIG. Canned beer products are inserted and placed.

  Next, as shown in FIG. 4 (a), the folding connection side piece 38 and the inner flap 35, and the bending connection side piece 38 and the inner flap 31 (on the other side of the conveyor (canned beer product insertion side), (Not yet folded) are sequentially folded along the crease line by the rotating second cam roller 120 as shown in FIG.

  Then, after being bent, the bent form is maintained by the conveyor guide 220 installed on the downstream side of the second cam roller 120, and is conveyed further downstream in this state.

  Next, as shown in FIG. 4B, the outer flaps 41 and 45 are bent while being folded so that the upper surface plate 25 is covered. Thereafter, the top plate 25 and the adhesive margin piece 9 are bonded together, and the outer flaps 41 and 45 and the inner flaps 31 and 35 are bonded to complete the assembly packing of the packaging box. In the present invention, the inner flap refers to a flap located on the inner side in the shipping box state, and the outer flap refers to a flap located on the outer side in the shipping box state.

(Description of essential parts of the packaging box of the present invention)
The upper surface plate 25 (FIG. 1) of the packaging box of the present invention is coated with an anti-slip paint over the entire surface. On the upper surface plate 25, a good-looking design reflecting the product image is printed on the entire surface, and an anti-slip paint is applied on the entire surface so as to coat the surface of the printed surface.

  On the other hand, the lower surface plate 21 (FIG. 1) is coated with a non-slip coating at an area A of y% over the entire surface. The remaining (100-y)% area B is not coated with anti-slip paint. In general, design printing is not performed on the lower surface plate 21, and an anti-slip coating is applied on a plain cardboard surface.

  An example of the application of a suitable anti-slip paint for the lower surface plate 21 is shown in FIG. As shown in FIG. 6, the area of area A where the anti-slip paint is applied to the bottom plate 21 is an outer peripheral area including the outer frame of the bottom plate, and the anti-slip paint is applied to the bottom plate 21. The area with no area B is the central area of the bottom plate. The area B is a central area of the lower surface plate, and for example, preferably has a rectangular shape substantially similar to the outer shape of the lower surface plate 21. The value of y (%) indicating the ratio of the area A to which the anti-slip paint is applied on the lower surface plate 21 (FIG. 1) is preferably y = 75% or more, particularly y = 75 to 85%. The reason why the anti-slip paint (anti-slip varnish) is applied to the upper surface plate 25 and the lower surface plate 21 is to prevent the occurrence of load misalignment when the packaging boxes are transported in a stacked state. If the y value of the lower surface plate 21 is less than 75%, there is a risk of misalignment.

  In the present invention, the application amount of the anti-slip paint on the lower surface plate 21 is suppressed to the minimum necessary amount that can exhibit the above-mentioned paint application effect, and as a result, the remaining anti-slip paint can exhibit the effects of the present invention. Therefore, it is applied to a predetermined area of the side plate and the outer flap near the notch corner (corner cut). Since the invention is configured on the assumption that the cost is not increased, the total usage amount of the anti-slip paint is set to be equal to or less than the conventional usage amount.

  Here, the main part of the present invention will be specifically described by taking one notch corner portion (corner cut portion; also referred to as a corner) shown in FIG. 5 as a representative example. Of course, similar settings are made in other corners.

  As shown in FIG. 5 (see also FIG. 1), the side plate 11 of the packaging box of the present invention folds the crease line 61 (65) at the joint between the side plate 11 and the bent connecting piece 38. In the vicinity of the first reference ridgeline (R1) formed in this way, at least two side plate application lines 111 and 112 of anti-slip paint disposed in parallel to the first reference ridgeline (R1) are applied. Yes.

  As shown in FIG. 5 (see also FIG. 1), the outer flaps 41 and 45 of the packaging box of the present invention have a crease line 62 (66) at the junction between the inner flap 31 and the bent connecting piece 28. In the vicinity of the second reference ridge line (R2) formed by folding, at least two anti-slip paint outer flap application lines 410 and 420 arranged in parallel to the second reference ridge line (R2) are applied. Has been. The outer flap application line 410 is composed of a combination of the lines 411 and 451 at the ends of the upper and lower outer flaps 41 and 45. In the drawing, the middle flap is omitted and it is not a complete line. Think of a combination line as a complete line. This is because the original effect of the invention can be expressed. Similarly, the outer flap application line 420 is composed of a combination of lines 412 and 452 at the ends of the upper and lower outer flaps 41 and 45. Even if some line deviation occurs, in the present invention, Such a combination line is also considered as one completed line. This is because the original effect of the invention can be expressed.

As shown in FIG. 5, one side plate coating line 111 arranged in parallel to the first reference ridge line (R1) in the present invention is the first side plate 11 side from the first reference ridge line (R1) to the side plate 11 side. This is an I-1 application line 111 of an anti-slip paint having a width L1 along one reference ridge line (R1). The other side plate coating line 112 is a first line centered on a parallel line at a position separated from the first reference ridge line (R1) by P ₁ mm (where P ₁ = 20 to 30 mm) toward the side plate 11. This is an I-2 application line 112 of an anti-slip paint having a width L2 formed substantially parallel to the reference ridgeline (R1).
Furthermore, as shown in FIG. 5, one outer flap application line 410 arranged in parallel to the second reference ridge line (R2) in the present invention is from the second reference ridge line (R2) to the outer flap side. It is the II-1 application line 410 of the anti-slip paint of width L3 along the 2nd reference ridgeline. Another outer flap application line 420 is a second line centering on a parallel line at a position separated from the second reference edge (R2) by P ₂ mm (where P ₂ = 20 to 30 mm) on the outer flap side. It is the II-2 application line 420 of the slip-proof coating material of width L4 formed substantially parallel to the reference ridgeline (R2).

  Such four coating lines 111, 112, 410.420 are formed in the vicinity of each of the four corners with the same specifications. This can be easily understood with reference to the development of the packaging box shown in FIG. Further, from the development shown in FIG. 1, the crease lines 61, 65, 81, and 85 form the first reference ridge line (R1), respectively, and the crease lines 62, 66, 82, and 86 are the second line, respectively. It can be seen that the reference ridge line (R2) is formed. Further, the side plate application lines 151 and 152 of the anti-slip paint on the side plate 15 form an I-1 application line 151 of the anti-slip paint and an I-2 application line 152 of the anti-slip paint, respectively. I understand that.

In the present invention, the I-1 coating line 111, 151, the I-2 coating line 112, 152, the II-1 coating line 410 (411 + 451), and the II-2 coating line 420 (412 + 452) When the total area of the lines to be formed is St, in relation to the area B in the lower surface plate 21, the following formula (1)
B ≧ St (1)
The I-1 application line, the I-2 application line, the II-1 application line, and the II-2 application line are formed so that In addition to the conventional function, an effect of ease of holding of the present invention is to be expressed while suppressing an increase in cost.

  The width L1 of the (1-1) th application line 111, 151 is at least 5 mm, and is preferably set in the range of 5-9 mm. As shown, one side of the line is formed along (in contact with) the first reference ridge line (R1).

Further, the width L2 of the I-2 coating lines 112 and 152 is at least 8 mm, and is preferably set in the range of 8 to 12 mm. P ₁ is in the range of 20-30 mm.

  Further, the width L3 of the II-1 application line 410 (411 + 451) is at least 5 mm, and is preferably set in the range of 5 to 9 mm.

The width L4 of the II-2 application line 420 (412 + 452) is at least 8 mm, and is preferably set in the range of 8 to 12 mm. P ₂ is in the range of 20~30mm.

  The specifications of each line are obtained as a result of intensive experiments conducted by the inventor of the present invention while strictly adhering to the condition of B ≧ St. Even if you hold it in front of your body, the corner cut part will be firmly caught by your palm and finger joints, and you will feel that it is easy to hold. The coating specifications for each line are preferably solid coating with a coating rate of 100%, but various coating pattern specifications with a coating rate of 60% or more (preferably 75 to 95%) can also be used.

  Further, no effect can be expected even if an anti-slip coating is applied to the corner cut surface corresponding to the bent connecting side piece 38. From the analysis of the pressure sensor and the like, it has been found that the corner-cut surface does not exert an anti-slip effect on the finger because the palm is positioned without the finger being applied. Pressure sensor analysis reveals that the area where the force is applied is the finger pad between the second and third joints of the four fingers excluding the thumb, the fingertips of the four fingers, and the finger pads and fingertips of the first and second joints of the thumb is doing.

  For these, refer to the experimental examples described later.

  In addition, the distance between the 1st reference ridgeline (R1) which prescribes | regulates the length of the bending connection side piece 38, and the 2nd reference ridgeline (R2) is about 25-30 mm.

  The anti-slip paint is synonymous with what is called an anti-slip varnish, and various known anti-slip paints used as anti-slip on cardboard or the like can be used.

(1) Sensory evaluation of easiness of holding Various samples in which anti-slip paint coating lines as shown in Table 1 below were formed in a packaging box having the same size as the current product specification were prepared.

  About these various samples, the sensory test of the easiness of holding was conducted with 10 male and 10 female panelists.

・ The first time was a gloves, the second was a bare hand, and the packaging box was held vertically in front of the body.
・ Evaluation of ease of holding the current product and each sample packaging box.
The overall evaluation criteria are as follows.
◎… Overall feel very good ○… Overall feel good △… I feel a little difficult to hold ×… I feel hard to hold The results are shown in Table 1 below.

(2) Ease of holding by pressure distribution, verification of holding difficulty Wearing white gloves with a pressure glove sensor (made by Nitta Co., Ltd.) in both hands and holding the packaging box vertically in front of the body While measuring the pressure of the fingers in the hand, we verified the ease of holding and the difficulty of holding.

  The product of the present invention can be felt as “easy to hold”, and in this case, the area where the force is applied is the finger pad between the second and third joints of the four fingers excluding the thumb, the fingertips of the four fingers, and the first of the thumb.・ It was revealed by the pressure sensor analysis that there were two joint finger pads and fingertips.

  In addition, in the conventional product that felt that it was “slippery and difficult to hold”, it was found by the analysis of the pressure sensor that the only part where the force was applied was the fingertip excluding the thumb.

  In addition, it was found by the analysis of the pressure sensor that the corner cut surface does not exert a finger and the palm is positioned, so that the effect of preventing slipping on the finger is not exhibited. Actually, even if the anti-slip paint was applied only to the corner cut surface, it did not feel “easy to hold”.

(3) Actual transportation test Actual transportation of about 2500 km was performed. Using a 12t truck (air suspension specification), a total of 56 packaging boxes, 8 sides and 7 steps on one pallet, were palletized and installed at the rear of the truck bed. After carrying out actual transportation of about 2500 Km, appearance inspection was performed on the state of dirt and sliding due to load slippage and application of anti-slip varnish on the side of the carton.

  If the value of y (%) indicating the ratio of the area A to which the anti-slip paint is applied on the lower surface plate 21 (FIG. 1) is 75% or more, it was confirmed that there is no problem such as load displacement. Furthermore, it was confirmed that there was no particular problem with the situation of dirt and rubbing by applying the anti-slip varnish of the present invention product (Examples 1 to 6 in Table 1).

From the above results, the effect of the present invention is clear.
That is, the present invention is a wrap-around type packaging box comprising a top plate, a bottom plate, and a belt-shaped body formed with side plates connecting them, and an inner flap and an outer flap. In order to form a top surface 4N square (N represents an integer of 2 or more), the top and bottom plates have cut-out corners (corner cut portions) at four corners, A bent connecting side piece is interposed at a location where the body portion is connected, and the upper surface plate is coated with an anti-slip paint on the entire surface thereof, and the lower surface plate is y% relative to the entire surface surface. The area A is coated with an anti-slip paint (where y is at least 75%), and the remaining (100-y)% area B is not coated with an anti-slip paint. Between the side plate and the bent connecting piece. In the vicinity of the first reference ridge line formed by folding the crease line at the joint portion, at least two anti-slip paint side plate coating lines arranged in parallel to the first reference ridge line are applied. The outer flap is disposed in parallel with the second reference ridgeline in the vicinity of the second reference ridgeline formed by mountain-folding the crease line at the joint portion between the inner flap and the bent connecting piece. In addition, at least two anti-slip paint outer flap coating lines are applied, and the two side plate coating lines arranged in parallel to the first reference ridge line are arranged on the side plate side from the first reference ridge line.
