Description

  The present invention relates to a packaging box and a blank sheet thereof in which measures against swelling of the body when a stacking load is applied.

  Corrugated packaging boxes (cardboard boxes) in which a plurality of beverage bottles are packed are widely distributed. A so-called assembly-type wrap round case is often used as a packaging box for such beverage bottles. In other words, a cardboard sheet in which a top plate, a bottom plate, and a pair of side plates are connected via a folding ruled line is folded so as to enclose a product group to be accommodated, and a joint wall of the side plate and the top plate are joined to form a peripheral wall. The inner flap formed and folded from both side plates is folded, and the outer flap extending from the top plate and the bottom plate is folded on the inner flap to seal both side surfaces of the peripheral wall.

  Such packaging boxes packed with beverage bottles are often stacked in multiple stages and stored in a warehouse or the like. The stacked lower packaging boxes are subjected to a stacking load on the top plate and are crushed, and the side plate or the like may be irregularly deformed outwardly, so-called torso.

  In order to suppress the deterioration of the appearance and appearance of the packaging box due to such swelling of the body, Patent Document 1 discloses a structure in which ruled portions are provided on the upper and lower sides of the side plate. When the body is swollen, the side plate is crushed along the ruled part to prevent irregular side swelling of the side plate.

JP 2013-203472 A

  However, the packaging box described in Patent Document 1 is not restricted in the deformation direction after the vicinity of the ruled portion of the side plate is crushed when the body is swollen. For this reason, the side plate is curved outward and swells, and irregular wrinkles may enter the center of the side plate.

  Since there are some purchasers who buy boxes of beverage PET bottles, they are often displayed at retail stores in the state of being packed in a packaging box. In such a display, irregular deformation of the packaging box due to the swelling of the body is not preferred because it may be a factor that reduces the willingness to purchase. In particular, there is a demand that the portion on which the product name or the like of the side plate is printed does not want to be deformed much.

  It is an object of the present invention to provide a packaging box and a blank sheet that suppress irregular deformation of a side plate and keep the appearance of an outer shape in a case of swelling due to a stacking load.

  The packaging box of the present invention is a pair of opposing first side plates and a pair of second side plates that face each other in a direction orthogonal to the opposing direction of the first side plates, and is connected to the sides of the first side plates. A packaging box having a second side plate, a top plate connected to the upper side of the first side plate, and a bottom plate connected to the lower side of the first side plate, wherein the first side plate is predetermined from each side. A pair of first vertical bent ruled lines extending in parallel with the side edges, positions of the first vertical bent ruled lines, and guide ruled lines connecting the side edges with the side edges at positions spaced apart from each other, and the pair of first vertical lines The second side plate comprises a ruled line connecting the upper end of a bent ruled line and extending parallel to the upper side, and a pair of laterally bent ruled lines connecting the lower end of the pair of first vertical bent ruled lines and extending parallel to the lower side, Are located at a position spaced apart from each side by the predetermined width. A pair of second vertical bent ruled lines extending in parallel with each other, and a guide ruled line connecting each end of the second vertical bent ruled line and the side, and at the corners of the first side plate and the second side plate And a deformation suppression surface surrounded by one of the first vertical bent ruled lines, one of the second vertical bent ruled lines, and the guide ruled lines on the first side plate side and the second side plate side.

  Therefore, even when the body is swollen, the laterally bent ruled line is buckled preferentially, while the deformation suppressing surface suppresses bending and deformation of other portions of the side plate.

  The first side plate may include a panel portion surrounded by the pair of first vertically bent ruled lines and the pair of horizontally bent ruled lines in the center.

  Further, each of the guide ruled lines in the first side plate is such that each end on the side is higher or lower than each end of the first vertical bent ruled line in the height direction of the first side plate. And extending at an angle from the side to the end of the first vertically bent ruled line, the guide ruled line on the second side plate is each end on the side, In the height direction of the second side plate, it is located closer to the upper side or the lower side than each end of the second vertical bent ruled line, and from the side to the end of the second vertical bent ruled line It may be inclined and extended.

  When a force is applied to the top plate such as a stacking load, the packaging box of the present invention is preferentially buckled by the laterally bent ruled line, and is laterally buckled by the deformation suppressing surface to a place other than the horizontally bent ruled line. To regulate. Thereby, irregular deformation | transformation, such as an irregular wrinkle entering into a side plate at the time of a trunk swelling, can be suppressed. In addition, because the panel part surrounded by these ruled lines slides outward due to the bending of the vertically bent ruled lines and the horizontal bent ruled lines, the box deformation due to the torso is less noticeable, and the box The beauty is not impaired. In addition, since the panel portion is located at a conspicuous portion in the center of the side plate, deformation of the printing surface can be suppressed even if characters or pictures are printed.

FIG. 2 is a development view of the packaging box according to the present invention (a view showing a blank sheet). FIG. 3 is a side view of the packaging box at the time of swelling according to the present invention. FIG. 4 is a partial perspective view showing the inside of the packaging box according to the present invention.

  A packaging box 10 in which a plurality of beverage bottles 100 such as PET bottles are arranged and housed includes a first side plate 12, a first width plate (hereinafter also referred to as “bottom plate”) 13, a second side plate 14, a second side plate 12. Width plate (hereinafter also referred to as “top plate”) 15 and a seam 16.

  In an assembled state, the first side plate 12 and the second side plate 14 face each other with the first width plate 13 as a bottom plate, and the second width plate 15 is used as a top plate and bonded together at a joint 16. The first inner flaps 22a and 22b are connected from both sides of the first side plate 12 via the creases C2a and C2b, respectively. Similarly, the second inner flaps 24a and 24b are connected from both sides of the second side plate 14 via the creases C4a and C4b, respectively. The first outer flaps 23a and 23b are connected to both sides of the first width plate 13 via the creases C3a and C3b, respectively. Similarly, second outer flaps 25a and 25b are connected from both sides of the second width plate 15 via creases C5a and C5b, respectively. Note that the creases C2 and C4 are not continuous from the upper end to the lower end of the first side plate 12 and the second side plate 14, but have a deformation suppressing surface 60 to be described later, so that they are divided at the central portion. It has been made.

  In addition, the length of the side in the short direction of the inner flaps 22 and 24, that is, the length of the side in the direction perpendicular to each of the creases C2 and C4 is 1 / of the length of the side of the width plates 13 and 15. 2 Therefore, in the assembled state, the first inner flap 22a and the second inner flap 24a, and the first inner flap 22b and the second inner flap 24b face each other between the side plates 12 and 14 of the packaging box. To form a side surface. Then, the first outer flap 23 and the second outer flap 25 are folded on the first inner flap 22 and the second inner flap 24, and the outer flaps 23 and 25 are bonded to the inner flaps 22 and 24. The packaging box 10 is sealed by being joined.

  Further, the first side plate 12 and the joint 16 are connected via a score S1, and the first side plate 12 and the first width plate 13 are connected via a score S2, and the first width plate 13 and the first width plate 13 are connected to each other. The second side plate 14 is connected to the second side plate 14 via the score S3, and the second side plate 14 and the second width plate 15 are connected to each other via the score S4.

  In the present embodiment, the seam 16 is superposed on the inner side of the second width plate 15 so that the seam 16 is not exposed to the outside. However, the seam 16 may be overlaid on the outside of the second width plate 15 and exposed to the outside.

  In the present embodiment, an adhesive is used for joining the flaps and joints. However, the invention is not limited to this, and joining using various joining means such as a tape may be used.

  In the center of the second outer flaps 25a, 25b, a notch 17 serving as a hand hole is provided, and the second outer flaps 25a of the first inner flaps 22a, 22b and the second inner flaps 24a, 24b, A cut portion 18 is also provided at a position facing the cut portion 17 in a portion where 25b overlaps. By pushing the cut portion surrounded by the cut line and the ruled line into the box, the overlapping portion of the second outer flap 25, the first inner flap 22, and the second inner flap 24 is pushed into the box, It becomes a hole. When carrying the packaging box 10, the hand hole inserts a finger to make it easier to grip the box.

  Further, a liner cut portion 61 composed of two parallel liner cut lines spaced from each other by a predetermined width may be provided on the liner on the inner surface of the box from the side plate 12 to the inner flap 22. The liner cut portion 61 can be divided into two parts by separating the liner cut portion 61 from the box 10 with the liner cut portion 61 as a boundary. For this reason, a part of the bottle accommodated in the inside can be exposed by removing only the upper part of the box 10 by the liner cut part 61.

  Note that the names of the top, bottom, bottom plate, top plate, top side, bottom side, etc. of the packaging box 10 are those when the packaging box 10 is placed as shown in FIG. 1, and the packaging box of the present invention is placed in this way. It is not limited to only. Further, the cut portions 17 and 18 that become hand holes, the liner cut portion 61, and the like may not be provided. Further, instead of the liner cut portion, a cut tape may be used as the two-dividing means.

  The packaging box 10 of this embodiment stores a 2-liter plastic bottle. As shown in FIG. 1, the width L of the 1st width board 13 and the 2nd width board 15 substantially corresponds with the horizontal width for two bottles 100 to be stored. The width H of the first side plate 12 and the second side plate 14, that is, the height H of the packaging box 10 substantially matches the height of the bottle 100 to be stored. The packaging box 10 of this embodiment can store three plastic bottles vertically and two horizontally. Accordingly, the depth M substantially matches the length of the three plastic bottles arranged. Although the present embodiment is configured to store two rows of plastic bottles, the present invention is not limited to this, and can be applied to various forms such as one-row storage.

  The packaging box 10 is processed to prevent swelling of the body. This countermeasure will be described.

  As shown in FIGS. 1 and 2, the first side plate 12 is formed with vertically bent ruled lines 32a and 32b inward by a width p1 from both sides (creases C2a and C2b). Each of the vertically bent ruled lines 32a and 32b extends from a position lower than the upper side (score S1) of the side plate 12 by the length q1 to a position higher than the lower side (score S2) by the length q2. The lengths q1 and q2 are preferably the same. Further, the vertically bent ruled lines 32a and 32b extend parallel to the side.

  In addition, the first inner flaps 22a and 22b connected to the first side plate 12 are also formed with vertically bent ruled lines 32e and 32f inward by a width p1 from the creases C2a and C2b, respectively. The vertical bent ruled lines 32e and 32f are parallel to the vertical bent ruled lines 32a and 32b on the side plate 12 and have the same length.

  Further, both end portions of the vertically bent ruled line 32a are connected to each other by a crease C2a and guide ruled lines 42a and 42a ′. The guide ruled line 42a is a line whose one end is positioned on the score S1 side of the vertically bent ruled line 32a on the crease C2a and extends obliquely to one end of the vertically bent ruled line 32a. Similarly, the guiding ruled line 42a 'is a line that has one end positioned on the score S2 side of the vertically bent ruled line 32a on the crease C2a and extends obliquely to the other end of the vertically bent ruled line 32a. The guiding ruled lines 42a and 42a ′ are inclined with respect to the crease C2a within a range of 30 degrees to 60 degrees.

  Both ends of the other vertically bent ruled line 32b are also connected to the crease C2b by the guide ruled lines 42b and 42b ′. The positions from the upper and lower sides of the guide ruled lines 42b and 42b ′, and the inclination angle are the same as those of the guide ruled lines 42a and 42a ′.

  Similarly, the longitudinally bent ruled lines 32e and 32f of the first inner flaps 22a and 22b are connected to the creases C2a and C2b by the guide ruled lines 42c, 42c ′, 42d, and 42d ′. In other words, the guide ruled lines and the vertically bent ruled lines are arranged symmetrically with respect to the side plate 12 and the first inner flap 22a with the side of the first side plate 12 as an axis. A hexagonal surface surrounded by the guide ruled lines and the vertically bent ruled lines is defined as a deformation suppression surface 60.

  Further, the first side plate 12 is formed with a horizontally bent ruled line 32c that connects end portions on the upper side of the vertical bent ruled lines 32a and 32b and extends parallel to the upper side. In addition, a laterally bent ruled line 32d that extends in parallel to the lower side is formed by connecting the end portions on the lower side of each of the vertically bent ruled lines 32a and 32b. These guide ruled lines and bent ruled lines are formed as push ruled lines on the inner surface when the first side plate 12 is assembled.

  Further, a rectangular portion surrounded by the vertically bent ruled lines 32 a and 32 b and the horizontally bent ruled lines 32 c and 32 d in the side plate 12 is referred to as a panel unit 52.

  Similarly, the second side plate 14 is formed with longitudinally bent ruled lines 34a and 34b inward by a width p1 from both sides thereof, and a laterally bent ruled line 34c is formed inwardly from the upper side of the side plate 14 by a length q1. A laterally bent ruled line 34d is formed at a position that is formed and enters the inside by a length q1 from the upper side of the side plate.

  A rectangle surrounded by the vertically bent ruled lines 34 a and 34 b and the horizontally bent ruled lines 34 c and 34 d is referred to as a panel portion 54.

  In addition, both ends of the vertically bent ruled line 34a are connected by a crease C4a and guide ruled lines 44a and 44a '. Further, both ends of the vertically bent ruled line 34b are also connected by the crease C4b and the guide ruled lines 44b and 44b ′. The positions from the upper and lower sides of the guide ruled lines 44a, 44a ′, 44b, and 44b ′, and the inclination angle are the same as those of the first side plate 12.

  Further, similarly to the first inner flaps 22a and 22b, the second inner flaps 24a and 24b provided on both sides of the second side plate 14 are also vertically bent ruled lines 34e and 34f, guiding ruled lines 44c and 44c. ', 44d, 44d' are formed. And the deformation | transformation suppression surface 60 enclosed by the vertical bending ruled line of the 2nd side plate 14, the guide ruled line, the vertical bending ruled line of the 2nd inner flap 24, and the guide ruled line is provided.

  Each ruled line is formed in the same manner as the first side plate 12 and the first inner flap 22.

  The width p1 is preferably in the range of 5 mm or more and less than 15 mm. Especially about 10 mm is preferable. The lengths q1 and q2 are preferably in the range of H / 6 or more and less than H / 3 with respect to the height H of the side plates 12 and 14. In particular, a length of about H / 4 is preferable.

  In the assembled state, as shown in FIG. 1, at the corners (ridge lines) between the side plates 12, 14 and the inner flaps 23, 24, an elongated deformation suppressing surface 60 formed by a vertically bent ruled line and a guide ruled line appears at the center. It will be. In other words, a corner portion composed of the second side plate 14 and the second inner flap 24b will be described as an example. The center portion of the crease C4b is divided by the deformation suppressing surface 60 (see FIG. 2). Therefore, the vertically bent ruled lines 34b and 34f are respectively bent at the center. Therefore, the corner portion has a shape in which only the portion of the deformation suppressing surface 60 enters the inside of the box rather than the corner. In other words, the appearance is such that only the portion of the deformation suppressing surface 60 has its corners dropped. As shown in FIG. 4, even in the box, the deformation suppressing surface 60 enters the box inside the corner ridgeline. In general, since a beverage bottle is a substantially columnar shape or a columnar shape with a corner dropped, there is no restriction on accommodation even if there is a deformation suppressing surface 60 at a part of the corner.

  Next, the change of the box 10 when the bulge occurs will be described. As described above, packaging boxes containing PET bottles and the like are stacked and stored in a warehouse or the like. The packaging box positioned at the lower stage receives the weight of the plurality of boxes stacked on the top plate 15 in the storage for a long time. The force of the stacking load applied to the top plate 15 causes the box 10 to swell in the width L direction.

  At this time, as shown in FIG. 4, the packaging box 10 according to the present embodiment guides the force of the stacking load from the top plate 15 in the directions of arrows A1 and A2 via the guide ruled lines 42a and 42c. On the first side plate 12 side, by the force from the top plate 15, the laterally bent ruled line 32c connected to the guide ruled line 42a is buckled, and the broken line 42e connecting the guide ruled lines 42a and 42c is also buckled. Along with this, the panel unit 52 slides outward. In conjunction with this slide, the laterally bent ruled line 32d buckles. The same phenomenon occurs on the second side plate 14 side. Therefore, as shown in FIG. 3, the panel portions 52 and 54 protrude outwardly when the trunk is swollen. As described above, the side plates 12 and 14 are bent along the bent ruled lines, so that the panel portions 52 and 54 are deformed as if they are slid outward, so that the body swelling is not conspicuous. In addition, by guiding the force applied to the top plate 15 to each ruled line, irregular wrinkles are prevented from entering the surfaces of the panel portions 52 and 54 occupying most of the side plates 12 and 14.

  That is, when a force is applied to the top plate 15, the deformation in the height direction of the box 10 causes the triangular portion of the guide ruled lines 42 a and 42 c and the broken line 42 e on the deformation suppression surface 60 to be inclined more horizontally. It is absorbed by deforming to. With the deformation of the triangular portion, the laterally bent ruled line 32c is also buckled, and the panel portions 52 and 54 slide outward in the width direction.

  The guide ruled lines 42 and 44 are inclined lines extending from the upper side or the lower side rather than the ends of the vertically bent ruled lines, but the present invention is not limited to this. However, such an inclined straight line is effective in transmitting the force applied to the top plate 15 most efficiently to the horizontally bent ruled line.

  The side plates 12 and 14 of the packaging box 10 are the widest surfaces among the six surfaces constituting the box 10. Therefore, since the side plates 12 and 14 are conspicuous surfaces, the product name of the beverage bottle accommodated may be printed. If printing such as a product name is stored in the panel portions 52 and 54, a beautiful state can be maintained without causing the product name to be bent unnaturally even if a swollen body occurs.

  In addition, in the appearance of the box 10, since a deformation suppression surface appears at the corner portion, it is possible to bring about a visual effect by printing characters or pictures on this portion.

  Furthermore, the present invention should be construed only from the matters described in the claims, and in the above-described embodiments, all the changes and modifications included in the concept of the present invention are other than those described. Is possible.
