Description

  The present invention relates to a packaging box made of corrugated paper that can be broken across two adjacent wall surfaces.

  The packaging box is provided with first breaking means in the wall portion constituting the outer peripheral wall and the second breaking in the continuous top wall in order to enhance the display effect of the contained goods and improve the workability of taking out the goods. Some are provided with an open state in which two walls are broken.

  The first breaking means is constituted by a first piece zipper extending toward the boundary line with the top wall, and the second breaking means is constituted by a second piece zipper provided so as to be continuous with the first piece zipper. These piece zippers are provided with cut portions and non-cut portions alternately with a predetermined interval. Further, a guide cutting part for correcting the breaking direction is provided in front of the cutting part in the breaking direction.

  When the first piece zipper is configured by a cutting portion at an end that intersects the folding line that is a boundary portion with the top wall, the compressive strength against the vertical force applied when the packaging boxes are stacked is lowered. Moreover, when the packaging box falls, the impact causes a tear (break) from the end of the first piece zipper. Therefore, the end that intersects the folding line is constituted by a non-cutting portion.

  However, in the packaging box made of corrugated paper, when the wall portion is broken along the first breaking means and then the top wall is broken, only the back liner from the non-cut portion which is the end portion of the first breaking means. Tears and remains in a continuous state at the break edge. This is considered to be caused by the back liner being pulled by the operation at the time of opening and further being displaced in the breaking direction. In the worst case, since the back liner remains unbroken across the entire second rupture edge of the top wall, not only the display effect (external appearance) of the product is deteriorated but also the workability of taking out the product is deteriorated.

  On the other hand, Patent Document 1 describes a packaging box in which third breaking means including a single zipper is provided at a boundary portion between a wall portion and a ceiling wall. This packaging box can be in a first opened state in which the wall portion located on the side surface is separated from the top wall and in a second opened state in which only the top wall is separated. Moreover, since the 3rd fracture | rupture means comprises the edge part which cross | intersects the 1st and 2nd fracture | rupture means with a cutting line, when making it into a 1st opening state, only the back liner mentioned above remains in a fracture | rupture edge. Can be prevented.

  However, in the packaging box of Patent Document 1, since the cutting portion of the third breaking means is further located at the intersection of the first and second breaking means, the front liner at the corner is caught and the appearance is poor. There is an inconvenience of becoming. Moreover, since many cutting | disconnection parts are provided in a corner | angular part, there exists a problem that rigidity falls.

JP 2000-185733 A

  An object of the present invention is to provide a packaging box that can be reliably opened over two wall surfaces without impairing the appearance and rigidity.

In order to solve the above-mentioned problems, the packaging box of the present invention is made of corrugated paper in which corrugated continuous paper is disposed between a front liner located outside and a back liner located inside, and three or more wall portions are provided. An outer peripheral wall, and a top wall and a bottom wall that close the top and bottom surfaces of the outer peripheral wall, the first wall and the second wall being continuous through a folding line among the walls. In the two walls, the first wall is provided with first break means having a first break line in which cut portions and non-cut portions are alternately provided and an end portion intersecting with the folding line is the non-cut portion. In addition, the second wall is alternately provided with cut portions and non-cut portions so as to be continuous with the first break line, and breaks the corrugated cardboard forming the first wall along the first break means. After that, the corrugated cardboard constituting the second wall can be broken second The second breaking means having a disconnection provided, and, in the end portion that intersects the first break line of the fold lines, and a configuration in which the half-cut line is provided in which cutting the backing liner.
In this packaging box, it is preferable that the second breaking means is provided at a boundary portion between the first wall and the third wall adjacent to the second wall.

  In the packaging box of this invention, since the edge part of the 1st broken line which cross | intersects a folding line is comprised by the non-cut | disconnecting part, it can prevent that compressive strength falls. In addition, due to this non-cut portion, when the second wall is broken along the second breaking line following the first wall, there is a possibility that the back liner will not break, but at the end of the folding line, Since the half-cut line that cuts the back liner is provided, the remaining breakage can be minimized. Therefore, it is possible to prevent the back liner from remaining on the entire breaking edge of the second breaking means, deteriorating the appearance, deteriorating the display effect of the product, and deteriorating the take-out workability. Further, since the half-cut line is obtained by cutting the back liner, it is possible to minimize a decrease in rigidity and to prevent the appearance in the sealed state from being damaged.

The boundary between the first side wall 11A and the first inner flaps 18A and 18B is provided with a sixth folding line 24 and a first piece zipper 26 constituting the first breaking means, and the top wall 13 and the second outer wall A second piece zipper 27 constituting the second breaking means is provided at the boundary between the flaps 21A and 21B.

  The first side wall (first wall) 11A has a longitudinally extending cut tape 25 and a second folding line 14 as a first breaking means for breaking the corrugated cardboard 1 constituting the side wall 11A. The first piece zipper 26 described above, which is a first break line extending in the direction, is provided. The top wall (second wall) 13 is a second breaking line that is a second breaking line continuous with the first piece zipper 26 as a second breaking means for breaking the corrugated paper 1 constituting the ceiling wall 13. A two-piece zipper 27 is provided so as to extend in the vertical direction.

  The cut tape 25 is made of a resin (polypropylene) tape having an adhesive applied on one surface. The cut tape 25 is attached to the surface of the back liner 3 between both ends of the pair of first inner flaps 18A and 18B. That is, the cut tape 25 is stuck so as to be orthogonal to the center shin 4 constituting the corrugated cardboard 1. Further, the cut tape 25 is stuck in a state of a continuous sheet before punching out the corrugated cardboard 1, and in this state, it is punched out by a paper punching device.

  In addition, grip portions 28A and 28B serving as break starting points are provided at both ends of the first side wall 11A so as to be positioned on the cut tape 25. The grip portions 28A and 28B approach the cut tape 25 from a substantially C-shaped first cut portion 29 extending so as to cross the cut tape 25 and from a position spaced from both ends of the first cut portion 29 by a predetermined distance. And a pair of second cutting portions 30 extending inwardly in a slanting manner. The outer flaps 20A, 20B, 21A, and 21B are provided with a punching portion 31 for preventing the gripping operation from being hindered at a portion where the gripping portions 28A and 28B are located.

  The first piece zipper 26 is provided from the upper side of the first cutting portion 29 to the second folding line 14 at the boundary portion between the side wall 11A and the first inner flaps 18A, 18B. The sixth folding line 24 is provided from the lower side of the first cutting portion 29 to the first folding line 12 at the boundary portion between the side wall 11A and the first inner flaps 18A and 18B. The second piece zipper 27 is provided from the second folding line 14 to the third folding line 16 at the boundary portion between the top wall 13 and the second outer flaps 21A, 21B. That is, the second piece zipper 27 is provided at a boundary portion between end walls (third walls) 17A and 17B adjacent to both the side wall 11A and the top wall 13.

  Each piece zipper 26 and 27 which is the 1st and 2nd breaking line is provided with cutting part 32 and non-cutting part 33 alternately so that it may be located on a straight line, and also has a breaking direction before the breaking direction of cutting part 32 This is the same as the conventional one provided with the guide cutting part 34 for correction. As shown in FIG. 6 (C), the cutting part 32 is cut by inserting a blade from the back liner 3 including the intermediate shin 4 to the front liner 2. The same applies to the first and second cutting portions 29 and 30 described above. Then, as shown in FIG. 5B, the first piece zipper 26 is configured with an uncut portion 33 at the end that intersects the second folding line 14. Similarly, the second piece zipper 27 is configured by an uncut portion 33 at an end that intersects the second folding line 14. However, since the second piece zipper 27 located on the top wall 13 side hardly affects the compressive strength, the end located on the second folding line 14 side may be constituted by the cutting part 32.

  In this embodiment, a half-cut line 35 is provided at the end of the second folding line 14 where each piece zipper 26, 27 intersects to prevent the back liner 3 from being largely broken. As shown in FIG. 6D, the half-cut line 35 cuts the back liner 3 by inserting a blade from the back liner 3 side, and the front liner 2 is an uncut portion that is not cut. . Although the intermediate shin 4 is shown in a state where it is cut halfway, it may not be cut when the extending direction and the blade direction are the same. Further, even when the direction of the middle shin 4 and the blade intersect as shown in the figure, the middle shin 4 may not be cut due to elastic deformation.

  The blank configured as described above is obtained by bending the side walls 11A and 11B with respect to the bottom wall 10, bending the top wall 13 with respect to the side wall 11A, and then bending the glued pieces 15 with respect to the top wall 13. The attaching piece 15 is attached to the upper end outer surface of the side wall 11B so as to overlap. Further, after the inner flaps 18A, 18B, 19A, 19B are bent with respect to the side walls 11A, 11B, the first outer flaps 20A, 20B are bent with respect to the bottom wall 10, and the second outer flap with respect to the top wall 13. 21A and 21B are bent, and these outer flaps 20A, 20B, 21A, and 21B are attached to overlap the outer surfaces of the inner flaps 18A, 18B, 19A, and 19B. Thereby, it can be set as the sealed state shown in FIG.

  Since this sealed packaging box is configured by the non-cutting portion 33 at the end of the first piece zipper 26 that intersects the second folding line 14, it is possible to prevent the compressive strength from being lowered. Moreover, since the broken part does not appear on the surface of the packaging box except for the gripping parts 28A and 28B for breaking and the piece zippers 26 and 27, the appearance can be prevented from being damaged.

  And in the store etc. to which goods were delivered using this packaging box, it is set as the opened state which fractured | ruptured and removed a part of side wall 11A and the top wall 13. FIG. Specifically, first, one gripping portion 28A is gripped and pulled toward the other gripping portion 28B. Thereby, as shown in FIG. 2, the side wall 11 </ b> A is torn by the cut tape 25. Note that the gripping portion 28B can be gripped and pulled toward the gripping portion 28A to be broken.

  Next, a hand is inserted into the breaking space formed by the cut tape 25, and the hand is put on the inside of the side wall 11A and pulled upward. Thereby, as shown to FIG. 3 (A), the upper part of 11 A of side walls can be fractured | ruptured along the 1st piece zipper 26. FIG. Then, following the breaking of the upper side wall 11A along the first piece zipper 26, the top wall 13 is broken along the second piece zipper 27 by pulling it upward while reversely folding the second folding curve 14. To do.

  At this time, the first piece zipper 26 of the present embodiment has the end portion on the second folding curve 14 side formed by the non-cutting portion 33, and therefore, as shown in FIG. As with the case, the back liner 3 may be left unbroken. However, in the present invention, since the half cut line 35 obtained by cutting the back liner 3 is provided at the end of the second folding line 14, when the half cut line 35 is reached, the remaining breakage of the back liner 3 is stopped. The

  Therefore, as shown in FIG. 4, in a state where the top wall 13 is broken along the second piece zipper 27, it is possible to minimize the occurrence of the remaining breakage of the back liner 3 at each broken edge. That is, as shown in the drawing, the back liner 3 can be left unbroken at the break edge of the second piece zipper 27 that can be easily seen by the purchaser. Therefore, it is possible to prevent the appearance in the opened state from being deteriorated and the display effect of the product from being lowered or the take-out workability from being impaired. Further, since the half-cut line 35 is obtained by cutting the back liner 3, it is possible to minimize a decrease in rigidity in the sealed state.

  In addition, the packaging box of this invention is not limited to the structure of the said embodiment, A various change is possible.

  For example, in the above-described embodiment, the first piece zipper 26 constituting the first breaking means is provided at the boundary portion between the side wall 11A and the first inner flaps 18A and 18B, and the second piece zipper 27 constituting the second breaking means is attached to the ceiling. Although provided at the boundary between the wall 13 and the second outer flaps 21A and 21B, as shown in FIG.

  Moreover, in the said embodiment, the edge of the half cut line 35 is made into the edge of the 1st and 2nd piece zipper 26 and 27 (slit between 1st inner flap 18A, 18B and 2nd outer flap 21A, 21B). The half cut lines 35 may be provided so as to intersect with each other with a predetermined interval (for example, 1 mm or less) as long as the purpose of preventing the back liner 3 from being broken is achieved.

  Furthermore, in the said embodiment, although the 1st fracture | rupture means was comprised by the cut tape 25 and the 1st piece zipper 26, you may comprise instead of the cut tape 25 by the zipper which provided the piece zipper symmetrically with the predetermined space | interval. Alternatively, by providing the first piece zipper 26 so as to have a substantially semicircular shape, the first breaking means may be constituted only by the first piece zipper 26. Furthermore, the second breaking means is constituted only by the second direction zipper, but a third breaking line may be further provided so that the pair of second piece zippers 27 are continuous.

  Moreover, in the said embodiment, although the 1st fracture | rupture means was provided in the side wall 11A and the 2nd fracture | rupture means was provided in the top wall 13, if it is a wall which continues through a folding line, it is applicable similarly, Actions and effects can be obtained. And in the said embodiment, although it was set as the packaging box which makes a planar view rectangular shape, the planar view octagon shape and planar view hexagonal shape which provided the chamfering wall in the boundary part of side wall 11A, 11B and end wall 17A, 17B It is good also as a box. That is, the present invention can be similarly applied to any packaging box including an outer peripheral wall having three or more wall portions, and a top wall 13 and a bottom wall 10 that close the top and bottom surfaces of the outer peripheral wall. And can get the effect.
