After the contents are taken out, the top panel 4 can be reused more effectively as a storage case with a lid or a packaging case for delivery. It will be available.

  6 to 10 show a second example of the packaging case according to the present invention, FIG. 6 is a development view of the packaging case of this example, and FIG. 7 is provided at the open side edge of the front panel of FIG. FIG. 8 is a perspective view showing a state before the packaging case of this example is opened, and FIG. 9 is FIG. FIG. 10 is a perspective view showing a state where the contents are omitted in a state where the top panel of the packaging case shown in FIG. 8 is opened, and FIG. 10 is a perspective view showing an example of a state where the packaging case shown in FIG. is there.

  As in the first example, the packing case of the present example includes a front panel 1, a bottom panel 2, a back panel 3, and a top panel 4 that are connected in the horizontal direction via vertical folding lines i, b, c in the unfolded state. The front panel 1 and the back panel 3 are respectively connected to both ends in the vertical direction through the inner side panels 5 and 6 connected through the horizontal folding lines D and E, and the both ends in the vertical direction of the bottom panel 2 and the top panel 4 respectively. The vertical folding lines are connected to the outer side panels 7 and 8 which are connected to each other through the horizontal folding lines and overlapped and bonded to the outer side of the inner side panels 5 and 6 and the top panel 4 which is bonded to the front panel 1. And a gluing flap 9 connected to each other.

  The outer surface panel 8 connected to both ends of the top panel 4 via a horizontal folding line is provided with a glue margin 11 so that a non-adhesive part 10 remains between the lateral folding line and this non-adhesion. The portion 10 is provided with a cutting portion 12 made of two perforations or cut tape along the horizontal folding line G with a predetermined interval between the horizontal folding line G. In this example, similarly to the first example, the cutting part 12 is formed of a cut tape. With the above configuration, there is no difference from the first example.

  In this example, the front panel 1 is provided with a cutting portion 21 made of a cut perforation or slit that forms intermittent recesses continuously along the open side edge, and a portion surrounded by the cutting portion 21 is A recess forming cut-out portion 22 is formed. The width dimension of the concave portion forming cut portion 22 and the convex portion 23 existing between each concave portion forming cut portion 22 is the concave portion forming cut portion width L1: convex portion width L2 = 2: 1.5 to 2: 0.5. Preferably there is.

  In the case where the width L2 of the recess formation cut portion L2 is 1.5 or more with respect to the recess formation cutout portion width L1, it is in a packaging case before opening as described later, and supports the force applied to the front panel 1 from the top panel 4 side. However, on the other hand, the adhesive strength between the convex portion 23 and the glued flap 9 is increased, and the separation between the convex portion 23 and the glued flap 9 becomes difficult. Moreover, in the packing case before opening as described later, when the concave portion forming cutout portion width L1 is 2 and the convex portion width L2 is 0.5 or less, the adhesive strength between the convex portion 23 and the glued flap 9 is Although the small protrusions 23 and the glued flaps 9 can be easily separated, the strength of the protrusions 23 that support the force applied to the front panel 1 from the top panel 4 side is weakened.

  In addition, although not shown in the drawings, the cutting part 21 that forms the concave portion exists between the concave portion forming cut portions 22 when the portion surrounded by the cutting portion 21 cuts the concave portion forming cut portions 22, and the front panel 1 is opened. It is preferable that the corner portion on the tip side of the convex portion 23 remaining on the side edge is provided so as to be rounded. If the corner portion on the tip side of the convex portion 23 is rounded, the corner portion on the tip side of the convex portion 23 is rounded when the glued flap 9 described later is inserted inside the front panel 1 and the top panel 4 is closed. If it is tinged, it is possible to prevent the hand from hurting at the corner on the tip side of the convex portion 23.

  Further, the adhesive portions 14 (portions indicated by hatching in FIG. 6) of the front panel 1 to be bonded to the adhesive margin portions 13 of the adhesive flap 9 connected to the top panel 4 are surrounded by the cutting portions 21. It is set on the recessed portion forming cutout portion 22. In the present example, the bonding portion 14 is set in a band shape so as to cross over the respective recess-forming cutout portions 22 along the open side edge of the front panel 4.

  Further, in this example, as in the first example, the glued flap 9 has a non-adhesive portion 17 having a predetermined width formed at the leading edge. The width of the non-adhesive portion 17 is easy to grasp at the time of opening, and when the top panel 4 is closed when resealing after opening, the non-adhesive portion 17 of the glued flap 9 is inserted inside the front panel 1. The dimensions are such that the top panel 4 can be temporarily fixed so as not to float.

  After opening, the top panel 4 has the remaining pieces 8a of the outer side panel 8 at both ends thereof, and the glued flaps 9 to which the cut pieces of the front panel are adhered are attached to the ends where the glued flaps 9 are connected. Since the remaining amount of the cut sheet or the like is taken out from the case body 18 thus opened, the opening is closed using the top panel 4 as a lid, and the top panel 4 By inserting the remaining pieces 8a of the outer side panel 8 remaining at both ends into the inner side panels 5 and 6 constituting the case body 18, the remaining pieces 8a of the outer side panel 8 are connected to the inner side panels 5 and 6 respectively. By locking and inserting the glued flap 9 inside the front panel 1, the glued flap 9 can be locked to the front panel 1, and the top panel 4 can be kept closed. Inside Etc. can be prevented from entering, and, after removal of the contents, and it can effectively reused as a housing case and shipping packing case with a lid.

  Further, as another resealing means, as shown in FIG. 10, the inner side panels 5, 6 constituting the case body 18 are made of the remaining pieces 8 a of the outer side panel 8 remaining at both ends of the top panel 4. The top panel 4 can be kept closed by closing the opening with the top panel 4 as a lid so that the glued flap 9 is inserted inside the front panel 1. In this case, since the top panel 4 does not fall into the case body 18, it sufficiently functions as a lid. After the contents are taken out, the top panel 4 can be reused more effectively as a storage case with a lid or a packaging case for delivery. It will be available.

  Moreover, in this example, the width dimension of the recessed part formation cutout part 22 and the convex part 23 which exists between each recessed part formation cutout part 22 is recessed part formation cutout part width L1: convex part width L2 = 2: 1.5-2. In the packaging case before opening, the convex portion 23 has a strength to support the force applied to the front panel 1 from the top panel 4 side, and the bending of the cut portion is ensured. Can be prevented.

FIG. 11 is a partially enlarged view of the developed packaging case of this example, and FIG. 12 is a top view of the packaging case of this example. It is a partially expanded perspective view which shows the state which opened the surface panel.

  The packaging case of this example has the same unfolded structure as the second example, the only difference from the second example is the configuration of the open side edge of the front panel 1, and the other configuration is the same as the second example. Only the different configuration will be described, and the description of the second example will be used for other configurations.

  In this example, the cutting portion 21 is provided at the center position of the open side edge of the front panel 1 provided with the cutting perforation or slit forming the recess in the packing case of the second example. A cutting portion 24 made of a cut perforation or slit that forms a central concave portion wider than the concave portion to be formed, and is bonded to the glued flap 9 connected to the top panel 1 to be bonded to the front panel 14 is also provided on a central recess forming cutout portion 25 surrounded by the cutting portion 24 (FIG. 11).

  In this example having such an unfolded structure, the case main body 18 is formed in the same manner as in the second example, and the opening case is sealed to complete a packing case in which contents such as a cut sheet are packed.

  In opening the sealed packaging case in this manner, as in the second example, first, the end of the cut tape constituting the cutting part 12 provided on the outer side panels 8, 8 is picked, Pull outward. As a result, the outer side panels 8 and 8 are cut at the position where the cutting portion 12 is provided, and are separated from the bonding portion with the inner side panels 5 and 6.

  Next, the glued flap 9 connected to the top panel 4 and bonded to the front panel 1 is pulled up from the open side edge in the peeling direction, and the cutting part 21 provided on the front panel 1 is cut to cut the cutting part. The recess forming cutout portions 22 surrounded by 21 and the central recess forming cutout portion 25 surrounded by the cutting portion 24 are cut out from the front panel 1, and at the same time, between the recess forming cutout portions 22 and between the recess forming cutout portions 22 and the central recess. The convex part 23 and the glued flap 9 which exist between the formation cut-out parts 25 are peeled off.

  In the case main body 18 having the opening opened in this way, a central concave portion forming cut portion 25 surrounded by the cutting portion 24 is cut out at the center position of the open side edge of the front panel 1 to form a central concave portion. Therefore, when taking out, for example, a cut sheet stored in the packaging case, it is easily taken out by inserting a finger from the central recess formed at the center position of the open side edge of the front panel 1. Can do. Since the other effects are the same as those of the second example, the description of the second example is cited.

  FIGS. 13 to 17 show a fourth example of the packaging case according to the present invention, FIG. 13 is a development view of the packaging case of this example, and FIG. 14 is provided at the open side edge of the front panel of FIG. FIG. 15 is a perspective view showing a state before opening of the packing case of the present example, FIG. 15 is a partially enlarged view showing a part of the cutout portion forming cutout portion and a portion of the noncutout portion existing between each cutout portion forming cutout portion. 16 is a perspective view showing a state where the top panel of the packaging case shown in FIG. 15 is opened and the contents are omitted, and FIG. 17 is an example of a state where the packaging case shown in FIG. 15 is opened and resealed. FIG.

  As in the first example, the packaging case of the present example includes a front panel 1, a bottom panel 2, a back panel 3, and a top panel 4 that are connected in the horizontal direction via vertical folding lines i, b, and c in the unfolded state. The front panel 1 and the back panel 3 are respectively connected to both ends in the vertical direction through the inner side panels 5 and 6 connected through the horizontal folding lines D and E, and the both ends in the vertical direction of the bottom panel 2 and the top panel 4 respectively. The vertical folding lines are connected to the outer side panels 7 and 8 which are connected to each other through the horizontal folding lines and overlapped and bonded to the outer side of the inner side panels 5 and 6 and the top panel 4 which is bonded to the front panel 1. And a gluing flap 9 connected to each other.

  The outer surface panel 8 connected to both ends of the top panel 4 via a horizontal folding line is provided with a glue margin 11 so that a non-adhesive part 10 remains between the lateral folding line and this non-adhesion. The portion 10 is provided with a cutting portion 12 made of two perforations or a cut tape along the horizontal folding line G with a predetermined interval between the horizontal folding line G. In this example, similarly to the first example, the cutting part 12 is formed of a cut tape. With the above configuration, there is no difference from the first example.

  In this example, the front panel 1 is provided with a cutting portion 26 formed by a perforation or slit for cutting that forms an intermittently continuous hollow portion along the open side edge, and is surrounded by the cutting portion 26. The portion is a hollow portion forming cutout portion 27. The hollow portion forming cutout portion 27 in this example is rectangular, but may be elliptical.

The width dimension of the cutout portion forming cutout portion 27 and the noncutout portion 28 existing between each cutout portion forming cutout portion 27 is cutout portion forming cutout portion width L3: non-cutout portion width L4 = 2: 1. It is preferably 5 to 2: 0.5.

  When the non-cut portion width L4 is 1.5 or more with respect to the hollow portion forming cut portion width L3 is 2, it is in a packaging case before opening as described later, and is applied to the front panel 1 from the top panel 4 side. The strength of the non-cutout portion 28 that supports the force increases, but on the other hand, the adhesive strength between the non-cutout portion 28 and the glued flap 9 increases, and the non-cutout portion 28 and the glued flap 9 are difficult to peel off. Further, when the uncut portion width L4 is 0.5 or less with respect to the hollow portion forming cut portion width L3, the uncut portion 28 and the glued flap 9 However, the strength of the non-cutout portion 28 which is a support for the force applied to the front panel 1 from the top panel 4 side is weakened.

  When the strength of the non-cutting portion 28 that supports the force applied to the front panel 1 from the top panel 4 side and the easy peelability of the non-cutting portion 28 and the glued flap 9 are made compatible, the hollow portion forming cut-out is performed. Part width L3: Most preferably, non-cut-out part width L4 = 2: 1.

  Further, an adhesive portion 14 (a portion indicated by hatching in FIG. 13) of the front panel 1 to be bonded to the adhesive margin portion 13 of the adhesive flap 9 connected to the top panel 4 is surrounded by a cutting portion 26. It is set on the cutout portion forming cutout portion 27. In this example, the bonding portion 14 is set in a band shape so as to cross over the hollow portion forming cutout portion 27 along the open side edge of the front panel 4.

  Further, in this example, as in the first example, the glued flap 9 has a non-adhesive portion 17 having a predetermined width formed at the leading edge. The width of the non-adhesive portion 17 is easy to grasp at the time of opening, and when the top panel 4 is closed when resealing after opening, the non-adhesive portion 17 of the glued flap 9 is inserted inside the front panel 1. The dimensions are such that the top panel 4 can be temporarily fixed so as not to float.

  In this example having such an unfolded structure, as in the first example, the front panel 1, the bottom panel 2, the back panel 3, the top panel 4, and the glued flap 9 are respectively formed from the vertical broken lines i, b, c, and h. The case main body 18 is formed by being folded in a valley and adhered to the adhesive portions 14 that are set in a band shape so that the glued flaps 9 traverse the respective cutout portion forming cutout portions 27 of the front panel 1.

  In this state, contents such as a cut sheet are accommodated in the case body 18, and then the inner side panels 5, 6 are valley-folded from the horizontal folding lines D, E, and further, from the horizontal folding lines, to the outer side. The panels 7 and 8 are valley-folded and stacked and bonded onto the inner side panels 5 and 6 to seal the opening, thereby completing a packing case in which contents such as cut sheets are packed. (FIG. 15).

  In opening the sealed packaging case in this way, first, the end of the cut tape constituting the cutting part 12 provided on the outer side panels 8 and 8 is picked and pulled outward. As a result, the outer side panels 8 and 8 are cut at the position where the cutting portion 12 is provided, and are separated from the bonding portion with the inner side panels 5 and 6.

  Next, the glued flap 9 connected to the top panel 4 and bonded to the front panel 1 is pulled up from the open side edge in the peeling direction, and the cutting part 26 provided on the front panel 1 is cut to cut the cutting part. Each cutout portion forming cutout portion 27 surrounded by the cutout portion 26 is cut out from the front panel 1 and, at the same time, the non-cutout portion 28 and the glued flap 9 existing between the cutout portion forming cutout portions 27 are peeled off.

  At this time, in this example, the width dimension of the cutout portion forming cutout portion 27 and the noncutout portion 28 existing between each cutout portion forming cutout portion 27 is the cutout portion forming cutout portion width L3: noncutout portion width. Since L4 = 2: 1.5 to 2: 0.5, the non-cut portion 28 and the glued flap 9 can be easily peeled off without requiring an excessive force.

  Further, in this example, the glued flap 9 is provided with the front panel 1 by picking and pulling up the non-adhesive portion 17 because the non-adhesive portion 17 having a predetermined width is formed at the edge of the front end. It is possible to easily cut the cut portion 26 and peel the non-cut portion 28 and the glued flap 9 from each other.

  In this way, three sides of the top panel 4 are opened, the top panel 4 is opened with a vertical fold line C between the top panel 4 and the back panel 3 as a hinge, the opening of the case body 18 is opened, and the packing case is opened. (FIG. 16).

  After opening, the top panel 4 has the remaining pieces 8a of the outer side panel 8 at both ends thereof, and the glued flaps 9 to which the cut pieces of the front panel are adhered are attached to the ends where the glued flaps 9 are connected. Since the remaining amount of the cut sheet or the like is taken out from the case body 18 thus opened, the opening is closed using the top panel 4 as a lid, and the top panel 4 By inserting the remaining pieces 8a of the outer side panel 8 remaining at both ends into the inner side panels 5 and 6 constituting the case body 18, the remaining pieces 8a of the outer side panel 8 are connected to the inner side panels 5 and 6 respectively. By locking and inserting the glued flap 9 inside the front panel 1, the glued flap 9 can be locked to the front panel 1, and the top panel 4 can be kept closed. Inside Etc. can be prevented from entering, and, after removal of the contents, and it can effectively reused as a housing case and shipping packing case with a lid.

  Further, as another resealing means, as shown in FIG. 17, the inner side panels 5, 6 constituting the case body 18 are made of the remaining pieces 8 a of the outer side panel 8 remaining at both ends of the top panel 4. The top panel 4 can be kept closed by closing the opening with the top panel 4 as a lid so that the glued flap 9 is inserted inside the front panel 1. In this case, since the top panel 4 does not fall into the case body 18, it sufficiently functions as a lid. After the contents are taken out, the top panel 4 can be reused more effectively as a storage case with a lid or a packaging case for delivery. It will be available.

  And in opening, each hollow part formation cut-out part 27 surrounded by the cut part 26 provided in the front panel 1 adhere | attached with the gluing flap 9 connected with the top | upper surface panel 4 is only cut off, and an open side Since the edges are connected in a straight line, there is little influence on the strength of the open side edge due to the presence of the hollow portion, and the top panel 4 can be stably kept closed when resealed.

  In addition, the packaging case before opening is provided with a cut portion 26 made of a cut perforation or slit that forms a hollow portion, but as described above, the open side edge of the front panel 1 is connected in a straight line. Since there is little influence on the strength of the open side edge due to the presence of the cut perforations or slits 26 forming the hollow portions, and the strength of the packing case is suppressed, Cases can be stacked without any problem.

  Further, in this example, the width dimension of the hollow formation cutout portion 27 and the non-cutout portion 28 existing between the respective hollow formation cutout portions 27 is the hollow formation cutout portion width L3: non-cutout portion width L4 = 2: Since it is 1.5-2: 0.5, in the packaging case before opening, the non-cut-out portion 28 has a strength to support the force applied to the front panel 1 from the top panel 4 side, The bending of the cut portion can be surely prevented.

  18 and 19 show a fifth example of the packaging case according to the present invention. FIG. 18 is a partially enlarged view of the developed packaging case of this example. FIG. 19 is a top view of the packaging case of this example. It is a partially expanded perspective view which shows the state which opened the surface panel.

  The packaging case of this example has the same unfolded structure as the fourth example. The only difference from the fourth example is the configuration of the open side edge of the front panel 1, and the other configurations are the same as the fourth example. Only the different configuration will be described, and the description of the fourth example will be used for the other configurations.

  In this example, at the center position of the open-side edge of the front panel 1 provided with the cutting perforations or slits 26 forming slits in the packing case of the fourth example. A glued flap connected to the top panel 1 is provided with a cut part 24 formed by a cut perforation or slit that forms a central recess wider than a hollow part formed by the same cut part 26 as in the three examples. 9 is also provided on a central recess forming cutout portion 25 surrounded by the cutting portion 24 (FIG. 18).

  In this example having such an unfolded structure, the case body 18 is formed in the same manner as in the fourth example, and the opening case is sealed to complete a packing case in which contents such as a cut sheet are packed.

  In opening the sealed packaging case in this way, as in the fourth example, first, the end of the cut tape constituting the cutting part 12 provided on the outer side panels 8, 8 is picked, Pull outward. As a result, the outer side panels 8 and 8 are cut at the position where the cutting portion 12 is provided, and are separated from the bonding portion with the inner side panels 5 and 6.

  Next, the glued flap 9 connected to the top panel 4 and bonded to the front panel 1 is pulled up from the open side edge in the peeling direction, and the cutting part 26 provided on the front panel 1 is cut to cut the cutting part. 26 is cut out from the front panel 1 between the cutout portion forming cutout portions 27 and the central recess formation cutout portion 25 surrounded by the cutout portion 24, and at the same time, between the cutout portion forming cutout portions 27 and the cutout portion formation. The non-cutout portion 28 and the glued flap 9 existing between the cutout portion 27 and the central recess forming cutout portion 25 are peeled off.

Since it is formed, when taking out, for example, a cut sheet stored in the packing case, it is easily taken out by inserting a finger from a central recess formed at the center position of the open side edge of the front panel 1. be able to. Since the other effects are the same as those of the fourth example, the description of the fourth example is cited.

  20 to 24 show a sixth example of the packaging case according to the present invention, FIG. 20 is a development view of the packaging case of this example, and FIG. 21 is provided at the open side edge of the front panel of FIG. FIG. 22 is an enlarged view showing a part of the recessed portion forming cutout portion, the hollow portion forming cutout portion, and the non-cutout portion existing between the concave portion forming cutout portion and the hollow portion forming cutout portion, FIG. FIG. 23 is a perspective view showing a state before opening, FIG. 23 is a perspective view showing a state in which the top panel of the packing case shown in FIG. 22 is opened, and contents are omitted, and FIG. 24 is a view showing the packing case shown in FIG. It is a perspective view which shows an example of the state resealed after.

  As in the first example, the packing case of the present example includes a front panel 1, a bottom panel 2, a back panel 3, and a top panel 4 that are connected in the horizontal direction via vertical folding lines i, b, c in the unfolded state. The front panel 1 and the back panel 3 are respectively connected to both ends in the vertical direction through the inner side panels 5 and 6 connected through the horizontal folding lines D and E, and the both ends in the vertical direction of the bottom panel 2 and the top panel 4 respectively. The vertical folding lines are connected to the outer side panels 7 and 8 which are connected to each other through the horizontal folding lines and overlapped and bonded to the outer side of the inner side panels 5 and 6 and the top panel 4 which is bonded to the front panel 1. And a gluing flap 9 connected to each other.

  The outer surface panel 8 connected to both ends of the top panel 4 via a horizontal folding line is provided with a glue margin 11 so that a non-adhesive part 10 remains between the lateral folding line and this non-adhesion. The portion 10 is provided with a cutting portion 12 made of two perforations or a cut tape along the horizontal folding line G with a predetermined interval between the horizontal folding line G. In this example, similarly to the first example, the cutting part 12 is formed of a cut tape. With the above configuration, there is no difference from the first example.

  In this example, the front panel 1 includes a cut perforation or slit forming a slit or a slit forming a continuous recess along the open side edge, and a cut perforation or slit forming a hollow portion. The cut portions 26 are alternately provided. A portion surrounded by the cut portions 21 is a concave portion forming cut portion 22, and a portion surrounded by the cut portions 26 is a hollow portion forming cut portion 27. The hollow portion forming cutout portion 27 has a rectangular shape, but may have an elliptical shape.

  The width dimension of the recessed portion forming cut portion 22 and the hollow portion forming cut portion 27 and the width size of the non-cut portion 28 existing between the recessed portion forming cut portion 22 and the hollow portion forming cut portion 27 are the width of the recessed portion forming cut portion L5. : Cutout portion forming cutout portion width L6: Non cutout portion width L7 = 2: 2: 1.5 to 2: 2: 0.5 is preferable.

  When the non-cut portion width L6 is 1.5 or more with respect to the concave portion forming cut portion width L5 and the hollow portion forming cut portion width L6, the front panel 1 has a packaging case before opening as described later. The strength of the non-cutout portion 28 that supports the force applied from the top panel 4 side increases, but on the other hand, the adhesive strength between the non-cutout portion 28 and the glued flap 9 increases and the non-cutout portion 28 and the glued flap 9 Peeling becomes difficult. In addition, when the non-cut portion width L6 is 0.5 or less with respect to the concave portion forming cut portion width L5 and the hollow portion forming cut portion width L6, it is in a packaging case before opening that will be described later. The adhesive strength between the portion 28 and the glued flap 9 is small, and the non-cutout portion 28 and the glued flap 9 are easily peeled off, but on the other hand, the non-cutout portion that supports the force applied to the front panel 1 from the top panel 4 side. The strength of 28 is weakened.

  When the strength of the non-cutting portion 28 that supports the force applied to the front panel 1 from the top panel 4 side and the easy peelability of the non-cutting portion 28 and the glued flap 9 are to be made compatible, the width of the cut-off portion forming the concave portion L5: Cutout portion forming cutout portion width L6: Non-cutout portion width L7 = 2: 2: 1 is most preferable.

  Further, an adhesive portion 14 (a portion indicated by hatching in FIG. 20) of the front panel 1 to be bonded to the adhesive margin portion 13 of the glued flap 9 connected to the top panel 4 is surrounded by the cutting portion 21. It is set on each hollow portion forming cutout portion 27 surrounded by the recess forming cutout portion 22 and the cutting portion 26. In this example, the adhesive portion 14 is set in a strip shape so as to cross over the respective recessed portion forming cut portions 22 and the respective hollow portion forming cut portions 27 along the open side edge of the front panel 4.

  Further, in this example, as in the first example, the glued flap 9 has a non-adhesive portion 17 having a predetermined width formed at the leading edge. The width of the non-adhesive portion 17 is easy to grasp at the time of opening, and when the top panel 4 is closed when resealing after opening, the non-adhesive portion 17 of the glued flap 9 is inserted inside the front panel 1. The dimensions are such that the top panel 4 can be temporarily fixed so as not to float up.

  In this example having such an unfolded structure, as in the first example, the front panel 1, the bottom panel 2, the back panel 3, the top panel 4, and the glued flap 9 are respectively formed from the vertical broken lines i, b, c, and h. The case main body 18 is formed by being folded in a valley and adhered to the adhesive portions 14 that are set in a band shape so that the glued flaps 9 traverse the respective cutout portion forming cutout portions 27 of the front panel 1.

  In this state, contents such as a cut sheet are accommodated in the case body 18, and then the inner side panels 5, 6 are valley-folded from the horizontal folding lines D, E, and further, from the horizontal folding lines, to the outer side. The panels 7 and 8 are valley-folded and stacked and bonded onto the inner side panels 5 and 6 to seal the opening, thereby completing a packing case in which contents such as cut sheets are packed. (FIG. 22).

  In opening the sealed packaging case in this way, first, the end of the cut tape constituting the cutting part 12 provided on the outer side panels 8 and 8 is picked and pulled outward. As a result, the outer side panels 8 and 8 are cut at the position where the cutting portion 12 is provided, and are separated from the bonding portion with the inner side panels 5 and 6.

  Next, the glued flap 9 connected to the top panel 4 and bonded to the front panel 1 was pulled up from the open side edge in the peeling direction, and surrounded by the cutting portions 21 and 26 provided on the front panel 1. Each recess-forming cut-out portion 22 and each cut-out portion forming cut-out portion 27 are cut from the front panel 1, and at the same time, a non-cut-off portion 28 existing between each recess-forming cut-out portion 22 and each cut-out portion forming cut-out portion 27 The gluing flap 9 is peeled off.

  At this time, in this example, the width dimension of the recessed portion forming cut portion 22 and the hollow portion forming cut portion 27 and the width size of the non-cut portion 28 existing between the recessed portion forming cut portion 22 and the hollow portion forming cut portion 27 are: Concave part cutout part width L5: Cavity part cutout part width L6: Non-cutout part width L7 = 2: 2: 1.5-2: 2: 0.5 9 can be easily peeled off without requiring excessive force.

  Further, in this example, the glued flap 9 is provided with the front panel 1 by picking and pulling up the non-adhesive portion 17 because the non-adhesive portion 17 having a predetermined width is formed at the edge of the front end. It is possible to easily cut the cut portion 26 and peel the non-cut portion 28 and the glued flap 9 from each other.

  In this way, three sides of the top panel 4 are opened, the top panel 4 is opened with a vertical fold line C between the top panel 4 and the back panel 3 as a hinge, the opening of the case body 18 is opened, and the packing case is opened. (FIG. 23).

  After opening, the top panel 4 has the remaining pieces 8a of the outer side panel 8 at both ends thereof, and the glued flaps 9 to which the cut pieces of the front panel are adhered are attached to the ends where the glued flaps 9 are connected. Since the remaining amount of the cut sheet or the like is taken out from the case body 18 thus opened, the opening is closed using the top panel 4 as a lid, and the top panel 4 By inserting the remaining pieces 8a of the outer side panel 8 remaining at both ends into the inner side panels 5 and 6 constituting the case body 18, the remaining pieces 8a of the outer side panel 8 are connected to the inner side panels 5 and 6 respectively. By locking and inserting the glued flap 9 inside the front panel 1, the glued flap 9 can be locked to the front panel 1, and the top panel 4 can be kept closed. Inside Etc. can be prevented from entering, and, after removal of the contents, and it can effectively reused as a housing case and shipping packing case with a lid.

  Further, as another resealing means, as shown in FIG. 24, the inner side panels 5, 6 constituting the case main body 18 are formed from the remaining pieces 8 a of the outer side panel 8 remaining at both ends of the top panel 4. The top panel 4 can be kept closed by closing the opening with the top panel 4 as a lid so that the glued flap 9 is inserted inside the front panel 1. In this case, since the top panel 4 does not fall into the case body 18, it sufficiently functions as a lid. After the contents are taken out, the top panel 4 can be reused more effectively as a storage case with a lid or a packaging case for delivery. It will be available.

  And in opening, each recessed part formation cut-out part 22 surrounded by the cutting part 21 provided in the front panel 1 bonded to the glued flap 9 connected to the top panel 4 and the cutting part 26 and each hollow Only the part-forming cutout part 27 is cut off, and the presence of the recessed part and the hollow part has little influence on the strength of the open side edge, and the top panel 4 can be stably kept closed when resealed. .

  In addition, the packaging case before opening is provided with a cutting portion 21 made of a cut perforation or slit for forming a recess and a cutting portion 26 made of a cut perforation or slit for forming a hollow portion. The presence of the portions 21 and 26 has little influence on the strength of the open-side edge and suppresses a decrease in strength of the packaging case, so that the packaging cases can be stacked without any trouble.

  Further, in this example, the width dimension of the recessed portion forming cut portion 22 and the hollow portion forming cut portion 27 and the width size of the non-cut portion 28 existing between the recessed portion forming cut portion 22 and the hollow portion forming cut portion 27 are the concave portion. Formed cut-out portion width L5: Hollow cut-out portion formed cut-out portion width L6: Non-cut-out portion width L7 = 2: 2: 1.5-2: 2: 0.5, so in the packaging case before opening The non-cutout portion 28 has a strength to support the force applied to the front panel 1 from the top panel 4 side, and can reliably prevent the bending of the cut portion.
