  However, in the packaging box of Patent Document 1, when the outer flaps are opened, the outer flaps are peeled off with respect to the adhesive, or the inner flaps are peeled off with respect to the adhesive, so that the first inner flap can be removed. It may not be able to break along the break line. If the adhesive is applied to the rear end of the inner flap in the opening operation direction of the outer flap, the inner flap can be reliably broken along the first breaking line, but with this configuration, the adhesive is accommodated inside Can not be adopted because it adheres to the

  An object of the present invention is to provide a package in which the inner wall can be broken along a break line by the opening operation of the outer wall to securely separate the separation portion.

  In the present invention, at least one surface of the plurality of walls closing the outer peripheral portion is disposed on the inner wall having the separation portion partitioned by the inner wall breaking line and the outer surface side of the inner wall, and the adhesion portion is attached to the separation portion And an outer wall adhered through the first and second breaking portions extending to the front side of the set opening direction of the outer wall with the side of the bonding portion as a breaking start point; A second breaking portion extending rearward of the unsealing operation direction, the separation portion being on the rear side of the unsealing operation direction of the bonding portion from the breaking start point to the unsealing operation direction Provided is a package in which a peeling prevention crease is provided so as to extend in a crossing direction. Here, the separation preventing ruled line extending from the breaking start point is not limited to a strict form in which one end is located at the breaking start point, and one end is positioned at a distance from the breaking starting point, and the extended virtual line is the breaking start point It includes a substantial form that is located in the vicinity.

  According to this package, by operating the outer wall in the set opening direction, the separation portion of the inner wall is pulled outward through the adhesive portion. Then, the break start point located to the side of the bonding portion is pulled outward, and the separation portion is mountain-folded outward along the peeling prevention ruled line. In the inner wall fracture line from the fracture start point, the fracture of the inner wall proceeds from the fracture start point to the front side in the unsealing operation direction from the fracture start point, and the inner wall from the fracture start point to the back side in the unsealing operation direction from the fracture point Breaking of Then, the entire outer peripheral portion of the separation portion is broken along the inner wall breaking line, whereby the separation portion is separated from the inner wall.

  When the separation preventing ruled line is not provided in the separation portion, the separation portion is in a flat state flush with the inner wall even if the opening operation is performed. In this case, breaking along the second breaking part on the rear side in the direction of opening operation from the bonding part is difficult, and the outer wall or the inner wall may peel off from the bonding part before breaking. However, in the present invention, a shearing force acts between the separation portion and the inner wall by the separation portion bending along the separation preventing ruled line by the opening operation of the outer wall. Therefore, since the inner wall can be broken along the second breaking portion before the outer wall or the inner wall peels from the bonding portion, the separation portion can be surely separated from the inner wall.

  The peeling prevention ruled line is inclined rearward from the breaking start point in the opening direction. Further, the breaking start point is an end portion of a protruding portion that protrudes to the separation portion side. According to these aspects, the force with which the outer wall is opened can be concentrated at the breaking start point by bending the separation part along the separation preventing ruled line. Therefore, the inner wall can be reliably broken along the first and second breaking portions from the breaking start point.

  In the present invention, when the outer wall is unsealed, the operating force is transmitted to the separation portion of the inner wall through the bonding portion, and the peeling prevention ruled line is bent, so that the first and second fracture portions start from the fracture start point. The inner wall can be broken along. In particular, the second breaking portion on the rear side in the unsealing operation direction from the breaking start point is surely broken by the shearing force generated between the separating portion and the inner wall when the separating portion is bent. Therefore, it can prevent that an outer wall or an inner wall peels from an adhesion part at the time of opening operation, and can separate a separation part from an inner wall certainly.

A pair of openings 13 and 13 are formed at both ends of the box body 12. The opening 13 is closed by a pair of inner flaps 24A and 24B which are inner walls and a pair of outer flaps 27 and 30 which are outer walls. The pair of flaps 24A, 24B, 27, 30 respectively form end walls 33A, 33B for closing one surface (end) of the outer peripheral portion of the packaging box 10.

  The packaging box 10 is formed by punching a corrugated paperboard sheet as a single blank shown in FIG. 3 by means of a well-known container punching device. Corrugated sheets are a well known arrangement in which a corrugated centerline is disposed between the front and back liners. The alternate long and short dash line in FIG. 3 indicates a folding line formed of a general-purpose ruled line formed by scribing from the back liner side so as to compress the thickness. The solid line in each figure shows a cutting line formed by inserting a blade from the front liner to the back liner.

  As shown in FIGS. 1 and 2, the box body 12 includes a bottom wall 15, a pair of side walls 16 </ b> A and 16 </ b> B, and a top wall 17. The bottom wall 15 and the top wall 17 are disposed parallel to each other in the facing position. The first side wall 16 </ b> A and the second side wall 16 </ b> B are disposed in parallel to other opposing positions, and are disposed adjacent to the bottom wall 15 and the top wall 17. Referring to FIG. 3, the walls 15 to 17 are rectangular in shape, and are connected in the order of the top wall 17, the first side wall 16A, the bottom wall 15, and the second side wall 16B from the left side. On the side wall 16B at the right end, a substantially strip-shaped adhesive margin wall 18 is further connected in order to adhere to the edge on the inner surface side of the top wall 17 at the left end.

  The bottom wall 15 and the pair of side walls 16A and 16B are continuous via fold lines 20a and 20b formed of general-purpose ruled lines. The side wall 16A and the top wall 17 extend in parallel to the fold lines 20a and 20b, and are continuous through the dividing line 21 which can be folded and broken. Referring to FIG. 3, the dividing line 21 is formed of a first cutting line provided in perforations at predetermined intervals, and a second cutting line extending obliquely from one end of the first cutting line to the ceiling wall 17 side. It consists of a zipper. The side wall 16B and the glue allowance wall 18 are continuous via a fold line 22 formed of a general ruled line extending parallel to the fold lines 20a and 20b.

  Inner flaps 24A and 24B are respectively connected to the end edges of the side walls 16A and 16B via fold lines 25. A first outer flap 27 is connected to an edge of the bottom wall 15 via a fold line 28, and a second outer flap 30 is connected to an edge of the top wall 17 via a fold line 31. There is. The fold lines 25, 28, 31 extend in a direction orthogonal to the fold lines 20a, 20b. The inner flaps 24A and 24B are formed to close the approximately half area of the opening 13, respectively. The outer flaps 27 and 30 are disposed to overlap the outer surface side of the inner flaps 24A and 24B.

  The total height T1 of the first outer flap 27 which is a dimension projecting from the bottom wall 15 is lower than the total height T2 of the second outer flap 30 which is a dimension projecting from the top wall 17. Further, the dimension of the total height T1 and T2 of the outer flaps 27 and 30 is smaller than the total height T of the box body 12 which is the dimension from the bottom wall 15 to the top wall 17. A gap of a predetermined distance is formed between the tips of the first outer flap 27 and the second outer flap 30, and the inner flaps 24A and 24B are exposed from the gap. The inner flaps 24A, 24B and the outer flaps 27, 30 are bonded via the bonding portion 35. As a result, an integrated single end wall 33A, 33B for closing each opening 13 is formed. As the adhesive constituting the bonding portion 35, a hot melt resin (hot melt) or a vinyl acetate emulsion type is used.

  In the following description, the width direction of the packaging box 10 from one side wall 16A to the other side wall 16B is the X direction, and the height direction of the packaging box 10 from the bottom wall 15 to the top wall 17 is the Y direction, The extension direction of the box body 12 from the one end wall 33A to the other end wall 33B is referred to as the Z direction.

  As shown in FIGS. 4 and 6, in the packaging box 10, an outer separation portion for opening the upper region of the ceiling wall 17 from the top wall 17 to a part of the end walls 33A and 33B to expose the inside of the packaging box 10. 37 and inner separation parts 40A, 40B are provided. The outer separation portion 37 is the entire ceiling wall 17 and the entire second outer flap 30, and the inner separation portions 40A and 40B are parts of the inner flaps 24A and 24B.

  In this embodiment, in order to divide one half of the end wall 33A and the other half of the end wall 33B, the top wall 17 which is the outer separation portion 37 extends to both ends in the X direction at the center in the Z direction. A dividing line 42 is provided. The first separating portion 38A and the second separating portion 38B of the top wall 17 divided by the dividing line 42 can be separated from the side wall 16A by the dividing line 21.

  Referring to FIG. 3, the dividing line 42 is provided with a pressing portion 43 provided at the center of the ceiling wall 17 in the X direction and breaking portions 48 provided on both sides of the pressing portion 43 in the X direction. There is. The pressing portion 43 is divided by a bending line 44, a first breaking line 45, a second breaking line 46, and a third breaking line 47. The fold line 44 consists of a general ruled line extending in the X direction. The first breaking line 45 is a perforated cutting line extending outward in the X direction from the end of the folding line 44. The second breaking line 46 consists of a perforated cutting line extending parallel to the folding line 44. The third breaking line 47 is a perforated cutting line extending from the end of the second breaking line 46 to the outer end of the first breaking line 45. The fractured portion 48 is configured by providing a plurality of generally Y-shaped cutting lines which are bifurcated in the X direction center side, with a plurality of intervals in the X direction.

  As shown in FIGS. 2 and 4, the inner separation portions 40A and 40B are partitioned in the inner flaps 24A and 24B by providing the inner flaps 24A and 24B with breaking lines (inner wall breaking lines) 50. The inner separation portions 40A and 40B of the present embodiment are configured such that a pair of inner flaps 24A and 24B adjacent in the X direction have a substantially regular pentagonal shape. A second outer flap 30, which is an outer separation portion 37, is disposed on the outer surface side of the inner separation portions 40A and 40B in a superimposed manner and is adhered via an adhesive portion 35. Further, the portions other than the inner separation portions 40A and 40B of the inner flaps 24A and 24B are not bonded to the second outer flap 30 by the bonding portion 35. Thus, the inner separation portions 40A and 40B can be separated together with the separation of the second outer flap 30 by opening the outer separation portion 37. The unsealing operation direction in the outer separation portion 37 is outward in the Z direction, and the unsealing operation direction in the end walls 33A and 33B is generally outward in the Z direction and downward in the Y direction.

  The breaking line 50 is set such that the side of the bonding portion 35 is the breaking start point 52. The side of the bonding portion 35 is the outside of the bonding portion 35 which is the direction X orthogonal to the breaking operation direction Y. Specifically, the fracture line 50 includes a fracture start part 53 including the fracture start point 52, a first fracture part 64 extending from the fracture start part 53 to the front side in the unsealing operation direction (downward in the Y direction in FIG. 2), A second breaking portion 66 is provided extending from the start portion 53 to the rear side in the unsealing operation direction (the upper side in the Y direction in FIG. 2).

  The breaking start portion 53 is provided with a base cutting line 57 extending from the breaking start point 52 in parallel along the bending line 25 downward in the Y direction. At a lower end portion of the base cutting line 57, a first cutting line 58 bent outward in the X direction with respect to the base cutting line 57 is provided. At an end portion of the first cutting line 58, a second cutting line 59 which is bent and extends downward in the Y direction is provided. Further, the breaking start portion 53 is provided with a third cutting line 61 which is bent outward in the X direction with respect to the base cutting line 57. At the end of the third cutting line 61, a fourth cutting line 62 is provided which is bent and extends upward in the Y direction. The cutting lines 57 to 62 are continuous from the second cutting line 59 on the lower end side to the fourth cutting line 62 on the upper end side. The breaking start point 52 is an intersection point of the base cutting line 57 and the third cutting line 61, and is an end of a protruding part that protrudes toward the inner separation parts 40A and 40B at the breaking start part 53.

  The first breaking portion 64 is formed of a one-piece zipper extending from the end of the second cutting line 59 to the tip (edge located at the center in the X direction) of the inner flaps 24A, 24B. The first breaking portion 64 is inclined downward in the Y direction toward the center in the X direction so that the tip is located between the tips of the outer flaps 27 and 30. The second breaking portion 66 is formed of a single zipper that extends from the end of the fourth cutting line 62 to the upper end (the edge located on the upper side in the Y direction) of the inner flaps 24A, 24B. The second fracture portion 66 is inclined to gradually spread outward in the X direction as it goes upward in the Y direction.

  When the outer separation portion 37 is grasped and the opening operation is performed and the second outer flap 30 is pulled in the opening operation direction, the operation force is transmitted to the inner separation portions 40A and 40B via the bonding portion 35. However, the unsealing operation force acts to break along the first breaking portion 64 located on the front side in the unsealing operation direction, but breaks along the second breaking portion 66 located on the rear side in the unsealing operation direction. It does not work as well. Therefore, before the inner flaps 24A and 24B break along the second breaking portion 66, the inner flaps 24A and 24B or the outer flaps 27 and 30 may peel off from the bonding portion 35.

  In order to prevent the peeling of the flaps 24A, 24B, 27, 30 from the adhesive portion 35, peeling prevention ruled lines 68 are provided on the inner side separation portions 40A, 40B of the present embodiment. The separation preventing ruled line 68 is provided on the upper side in the Y direction (rear side in the unsealing operation direction) than the bonding portion 35 of the inner side separation portions 40A and 40B. Further, the peeling prevention ruled line 68 is inclined inward in the X direction from the breaking start point 52 so as to extend in a direction intersecting the opening operation direction. The peeling prevention ruled line 68 is made of a lead crease having good bendability. This lead crease comprises a folding line 69 consisting of a general-purpose ruled line and a plurality of cutting lines 70 spaced along the folding line 69.

  Further, in the inner side separation portions 40A and 40B, auxiliary ruled lines 72 formed of general-purpose ruled lines are provided so as to be positioned symmetrically with respect to the peeling prevention ruled lines 68. The auxiliary ruled line 72 is provided so as to be located on the lower side of the base cutting line 57 below the bonding portion 35 in the Y direction (the front side in the unsealing operation direction). The auxiliary ruled line 72 is inclined inward in the X direction so as to extend in a direction intersecting the opening operation direction.

  When assembling the blank shown in FIG. 3, for example, a predetermined article is placed on the bottom wall 15, and the side walls 16A and 16B are bent with respect to the bottom wall 15. Next, an adhesive is applied to the glue allowance wall 18, and the glue allowance wall 18 is bent against the side wall 16B. Thereafter, the top wall 17 is bent with respect to the side wall 16A, and the top wall 17 and the glue allowance wall 18 are bonded.

  Next, an adhesive is applied between the separation preventing ruled line 68 and the auxiliary ruled line 72 of the inner separation portions 40A and 40B, and the first outer flap 27 of the inner flaps 24A and 24B outside the inner separation portions 40A and 40B. Apply an adhesive to the part where is superimposed. Then, the inner flaps 24A and 24B are bent inward with respect to the side walls 16A and 16B. Further, the first outer flap 27 is bent with respect to the bottom wall 15, and the second outer flap 30 is bent with respect to the top wall 17. Thereby, the inner flaps 24A, 24B and the outer flaps 27, 30 are bonded.

  For example, as shown in FIG. 4, when opening the packaging box 10, the pushing portion 43 is pushed inward from the outside of the top wall 17, and the first separating portion 38A is gripped to face upward in the Y direction and outward in the Z direction. pull. As a result, the first separation portion 38A of the ceiling wall 17 is peeled off from the bonding portion 35 of the glue margin wall 18, and the boundary between the first separation portion 38A and the side wall 16A is broken along the dividing line 21.

  Next, as shown in FIG. 5, the first separation portion 38A (the second outer flap 30) is pulled downward in the Y direction and outwardly in the Z direction. As a result, the inner separation portions 40A and 40B are pulled outward through the bonding portion 35. Then, the break start point 52 located on the side of the bonding portion 35 is pulled outward, and the inner separation portions 40A and 40B are mountain-folded outward along the separation preventing ruled line 68 and the auxiliary ruled line 72. At this time, the peeling prevention ruled line 68 is inclined rearward from the breaking start point 52 in the unsealing operation direction, and the breaking start point 52 is an end of a protrusion projecting toward the inner separation parts 40A and 40B. The force by the opening operation can be concentrated at the breaking start point 52.

  Then, by continuing the unsealing operation, the inner flaps 24A, 24B can be broken from the breakage start point 52 along the first breakage portion 64 downward in the Y direction. This is because the breaking operation direction and the extending direction of the first breaking portion 64 are the same. Further, the inner flaps 24A and 24B can be broken from the breaking start point 52 along the second breaking part 66 to the upper side in the Y direction. This is due to the bending of the inner separation portions 40A, 40B.

  The fracture along the second fracture portion 66 will be described in more detail. When the inner separation parts 40A and 40B are bent, the other parts of the inner separation parts 40A and 40B and the inner flaps 24A and 24B are inclined at different angles. As a result, a shearing force acts between the edge of the inner separation portions 40A and 40B along the second separation portion 38B and the edge of the inner flaps 24A and 24B. When the shear force for breaking along the second breaking portion 66 is compared with the force at which the second outer flap 30 or the inner flaps 24A and 24B peel from the bonding portion 35, the shear force is smaller. Therefore, the inner flaps 24A and 24B can be broken along the second breaking portion 66 before the second outer flap 30 or the inner flaps 24A and 24B peel off from the bonding portion 35.

  The entire outer peripheral portions of the inner separation portions 40A and 40B are broken along the break line 50, whereby the inner separation portions 40A and 40B are separated from the inner flaps 24A and 24B, as shown in FIG. Further, by separating the inner separation portions 40A and 40B from the inner flaps 24A and 24B, the inside of the packaging box 10 is exposed through the opening 13 of the box body 12. Further, by separating the outer separation portion 37 from the box body 12, the inside of the packaging box 10 is exposed also from above.

  As described above, in the packaging box 10 of the present embodiment, since the separation preventing ruled line 68 is provided in the inner separation portions 40A and 40B, the unsealing operation force of the second outer flap 30 is concentrated at the breaking start point 52 to break it. From the starting point 52, the inner flaps 24A, 24B can be reliably broken along the first broken part 64 and the second broken part 66. Therefore, the problem that the inner flaps 24A, 24B or the outer flaps 27, 30 are peeled off from the bonding portion 35 and the inner separation portions 40A, 40B can not be separated can be reliably prevented.

Second Embodiment
FIG. 7 shows the packaging box 10 of the second embodiment. In the second embodiment, the adjacently disposed inner flaps 24A, 24B are formed in a dimension in which the tips thereof do not butt each other, and the outer flaps 27 and 30 are formed in a dimension in which the tips thereof mutually abut, It differs from the first embodiment.

  In more detail, the folding line 22 formed between the side wall 16B and the setting wall 18 is constituted by a single zipper similar to the dividing line 21 which can be folded and broken. The inner separation portions 40A and 40B are set in a substantially upper half area where the second outer flaps 30 of the inner flaps 24A and 24B overlap. As breaking lines 50 for dividing the inner separation portions 40A and 40B, a first breaking portion 64 and a second breaking portion 66 are formed along the folding line 25. In addition, a third breaking portion 75 is provided to extend in the X direction at an intermediate portion of the inner flaps 24A, 24B in the substantially Y direction.

  The packaging box 10 according to the second embodiment is assembled in the same manner as in the first embodiment and can be opened as in the first embodiment. Then, the inner separation portions 40A and 40B can be separated from the inner flaps 24A and 24B without peeling the inner flaps 24A and 24B and the outer flaps 27 and 30 from the bonding portion 35.

Third Embodiment
FIG. 8 shows the packaging box 10 of the third embodiment. The third embodiment is different from the second embodiment in that the tip of the second outer flap 30 is gripped and opened without providing the dividing line 42 at the center of the ceiling wall 17. Further, in the third embodiment, a peeling prevention ruled line 68 is provided on the lower side in the Y direction of the bonding portion 35 which is the rear side of the second outer flap 30 with respect to the bonding portion 35 in the unsealing operation direction.

  The packaging box 10 of the second embodiment is assembled in the same manner as the first embodiment. Further, when the packaging box 10 is opened, by operating the second outer flap 30 upward in the Y direction and outward in the Z direction, as in the first embodiment, the inner flaps 24A, The inner separation portions 40A and 40B can be separated from the inner flaps 24A and 24B without peeling off the 24B and the outer flaps 27 and 30.
