  However, in the carton described in Patent Document 1, the operation tongue piece and the top plate are connected by a perforation having a bridge at the cutting portion, and the outer folded piece is bonded to the surface of the side plate on the front side of the carton. Therefore, the force required for pulling up the outer folded piece is increased, and there is a possibility that the powdered product is scattered at the time of opening. In addition, there is a problem that it is extremely difficult to control the width of the bridge in order to prevent the outer folded piece from being separated and reversed when the paper panel is folded, and to suppress an increase in the lifting force of the outer folded piece.

  On the other hand, the cartons described in Patent Document 2 and Patent Document 3 have a problem that the insertion opening of the operation tongue piece is small at the time of manufacturing the carton and cannot be easily opened / resealed, and the resealability is slightly inferior. Moreover, in the carton described in Patent Document 4, since the insertion opening of the operation tongue piece is provided so as to penetrate substantially the center in the height direction of the side plate, there is a possibility that the powder product leaks. Furthermore, in the carton described in Patent Document 5, when opening, it is necessary to cut between the outer folded piece and the side plate in front of the carton and to leave a part of the outer folded piece in the carton. there were.

  The present invention has been made in view of the above circumstances, and can weaken the pulling force of the outer folded piece required at the time of opening, can be easily opened / resealed, and has poor opening and manufacturing. It is an object of the present invention to provide a carton that can prevent occurrence of a paper jam at the time of boxing and that can easily form a cutting portion and a cut line when a paper panel is formed.

In order to solve the above problems, the present invention employs the following configuration.
That is, in the carton of the present invention, the outer folded piece, the top plate, the first side plate, the bottom plate, the second side plate, and the inner folded piece whose front end portions are operating tongue pieces are arranged in this order, Side flaps are provided on both sides of the side plate and the second side plate, main flaps are provided on both sides of the top plate and the bottom plate, and the outer side folds from the first side plate to both sides of the top plate. A linear first cut portion is formed in the direction of the piece, and a second cut portion is formed between the both end portions of the operation tongue piece from the both end portions of the first cut portion on the outer folded piece. The formed paper panel is formed in a box shape by bending each part, and the side flaps and the main flaps on both sides of the top plate, the first side plate, the bottom plate, and the second side plate. Is attached to the inner side of the second side plate. In the carton, which is attached and the outer folded piece is attached to the front side of the second side plate, leaving the operation tongue piece, the operation tongue piece on a portion corresponding to the operation tongue piece on the second side plate A cut portion is formed between both end portions in the width direction of the cut portion, and is cut with a depth from the both ends of the cut portion to the middle of the carton surface side in the thickness direction along the second cut portion. A first cut line is formed.

Further, in the carton of the present invention, wherein the outer folded piece, said in the outer folded piece on the front side of the second side plate is attached, the upper end of the second side plate at a position corresponding to the notch portion A bending imaginary line parallel to the edge is set, and when the outer folded piece is attached to the front side of the second side plate on the inner surface of the carton of the second side plate, It is preferable that a second cut line is formed which is positioned above the imaginary bending line and is cut with a depth from the inside to the middle of the carton in the thickness direction.
Furthermore, in the carton of the present invention, when the width of the operation tongue piece is smaller than the width of the first cut portions, and the outer folded piece is attached to the front side of the second side plate, first cut line extends so as to be widened toward the both end portions of the first cutting portion from both ends of the cut portion, and, with curved toward the upper edge of the second side plate Preferably it is formed .

  According to the above configuration, when the operating tongue piece is pulled up toward the upper side of the carton, the portion corresponding to the operating tongue piece includes the cut portion provided across the both ends in the width direction of the operating tongue piece, and the inner side. A part of the second side plate that is not attached to the folded piece is peeled off from the second side plate along with the outer folded piece. Subsequently, when the operation tongue piece is pulled up toward the upper side of the carton, a second side plate (hereinafter referred to as a peeling portion) from the surface side of the carton whose both ends are cut by the first cut line to the middle of the thickness direction is formed. It peels from a 2nd side board with an outer side return piece. That is, the delamination of the paper which comprises this 2nd side board generate | occur | produces in the 2nd side board which the both ends were cut by the 1st cut line. The force required for the peeling part to delaminate from the second side plate is the force required to peel the two sheets of paper that are stuck together and the cut line consisting of perforations with bridges. Since it is weaker than the necessary force, the peeling portion is delaminated from the second side plate by the relatively weak lifting force of the outer folded piece. In addition, the peeling part is connected to the second side plate from the inner side of the carton to the middle of the thickness direction until the operation tongue piece is pulled upward toward the upper side of the carton when it is opened for the first time. Is cut off from the second side plate and inverted so that it is not caught by a box making machine or the like, and no paper jam occurs. Furthermore, the first cut line may be formed from the surface side of the carton to the middle of the thickness direction, noting that it does not penetrate the paper panel. Even if there is a slight difference in the cut depth for each paper panel, The action of is retained. Therefore, no special control or the like is required when forming the first score line.

  Moreover, according to said structure, the part corresponding to an operation tongue piece contains the notch part provided over both ends in the width direction of this operation tongue piece, and the 2nd which is not stuck by the inner side folding piece Since a part of the side plate further includes a second cut line that is cut at a depth from the inside to the middle of the carton in the thickness direction, when the operating tongue piece is pulled upward toward the carton, A part of the second side plate is more easily separated from the second side plate with the outer folded piece by a weak pulling force.

  Furthermore, according to said structure, even if it is a case where the width | variety of an operation tongue piece is smaller than the width | variety of 1st cutting parts, it is cut off from a 2nd side plate as an operation tongue piece is pulled up toward a carton upper direction. The width of the peeled portion continuously increases. As a result, the peeled portion is smoothly separated from the second side plate, and then the lid formed by the center portion of the top plate in the width direction of the carton with the first cut portion as a boundary and the both side end portions of the top plate Transition to detachment.

  According to the present invention, it is possible to weaken the lifting force of the outer folded piece required at the time of opening, it is possible to easily open / reseal, and prevent occurrence of poor opening and paper jam at the time of box making, In addition, it is possible to provide a carton in which a cut portion and a cut line can be easily formed when a paper panel is created.

A cut 56 is formed by cutting.

  The paper constituting the paper panel 10 can be almost used as long as it is laminated by a generally used round net paper machine and has a multilayer structure.

  The carton of the present embodiment is formed in a box shape by bending each of the above-described components of the paper panel 10 by an assembly process described below.

  First, the folding line 62 </ b> A of the paper panel 10 shown in FIG. 1 is folded in a mountain, and the inner folded piece 22 and the second side plate 20 are adhered, leaving the insertion port forming portion 54. Thereafter, the folding line 62B is folded, the second side plate 20 is made to face the bottom plate 18, the folding line 62D is folded, the folding line 62E is overlapped with the folding line 62A, and the outer folding piece 12 is left leaving the operation tongue piece 13. Affixed to the second side plate 20.

  Next, the first side plate 16 and the second side plate 20 are raised by pushing the folding line 62D toward the folding line 62B while sucking the top plate 14. Next, the folding lines 62F and 62G are folded in a mountain, and the side flaps 24A and 26A are folded toward the inner side of the carton. Thereafter, the folding line 62H is folded in a mountain, and the main flap 28A is attached to the side flaps 24A and 26A. Further, the folding line 62I is folded in a mountain, and the main flap 30A is attached to the main flap 28A. As a result, one laminated side plate of the carton of this embodiment composed of the side flaps 24A and 26A and the main flaps 28A and 30A is formed.

  Next, a carton is erected with the laminated side plate as the bottom, and a predetermined amount of powder is inserted into the inner space of the carton surrounded by the top plate 14, the bottom plate 18, and the first and second side plates 16, 20 To do. Thereafter, the folding lines 62J and 62K are folded in a mountain and the side flaps 24B and 26B are folded toward the inner side of the carton, and the folding line 62L is folded in a mountain and the main flap 28B is attached to the side flaps 24B and 26B. Further, the folding line 62M is folded in a mountain, and the main flap 30B is attached to the main flap 28B.

  The carton of this embodiment is completed through the above steps. FIG. 3 is a perspective view of the carton 100 of the present embodiment in which the paper panel 10 is bent by the assembly process described above. As shown in FIG. 3, the carton 100 includes at least the top plate 14, the bottom plate 18, the first and second side plates 16 and 20, the laminated side plates 70 and 72, and the outer folded piece 12 as viewed from the front side. And an operating tongue piece 13. The carton 100 is sealed and filled with a powder (not shown).

  4 to 7 are views showing how the carton 100 is opened, and FIGS. 4, 6 and 7 are perspective views of the carton 100, and FIG. 5 is an arrow along the line XX shown in FIG. It is sectional drawing of the carton 100 at the time of seeing. When unsealing the carton 100 in the sealed state shown in FIG. 3, as shown in FIGS. 4 and 5A, when the operating tongue 13 is picked and pulled upward as indicated by an arrow, first, as shown in FIG. As shown in b), a part 20p of the second side plate 20 surrounded by the notch 44 and the second notch line 50 is peeled away from the notch 44 toward the second notch line 50, and affixed. The outer folded piece 12 attached by the adhesive 74 is pulled up. Subsequently, the second side plate 20 in which both ends in the width direction of the carton are cut by the first cut lines 46 with a depth from the carton surface side in the thickness direction (that is, the left side of the paper surface in FIG. 5) to the middle, With the end portion 76 on the inner side of the second side plate 20 of the second cut line 50 as a base end, delamination occurs between the peeling piece 78 and the peeling piece 80 at the boundary 20S in the direction away from the cutting portion 44. Since the inside of the carton 100 of the peeling piece 78 is stuck to the inner folded piece 22 by the sticking agent 74, the peeling piece 78 remains with the inner folded piece 22. On the other hand, since the surface side of the carton of the peeling piece 80 is stuck to the outer folded piece 12 by the sticking agent 74, the peeling piece 80 is pulled up along with the outer folded piece 12.

  As shown in FIG. 6, after the outer folded piece 12 is pulled up to the both end portions 34A and 34B via the operating tongue piece 13, when the operating tongue piece 13 is further lifted, the outer folded piece 12 as shown in FIG. Accordingly, the top plate 14 between the first cutting portions 32 is detached from the surroundings and becomes a lid 82. In this way, the carton 100 can be opened.

  8A and 8B are views showing the carton 100 in a resealed state, in which FIG. 8A is a perspective view of the carton 100, and FIG. 8B is a carton when viewed in the YY line shown in FIG. FIG. When the carton 100 after opening shown in FIG. 7 is resealed, as shown in FIGS. 8A and 8B, the operating tongue 13 is moved from the cut portion 44 of the second side plate 20 to the cut portion 44. , 45 and is inserted into the space between the second side plate 20 and the insertion port forming portion 54 of the inner folded piece 22. As a result, the operating tongue 13 is held between the second side plate 20 and the inner folded piece 22, and a part 20 p of the second side plate 20 is locked to the peeling piece 78 as shown in FIG. Then, the operation tongue piece 13 and the outer folded piece 12 are fixed to the surface side of the second side plate 20.

  When the carton 100 in the resealed state shown in FIG. 8 is opened, the operation tongue piece 13 is pulled out from between the second side plate 20 and the inner folded piece 22 by gently pushing the outer folded piece 12 upward. Thereafter, when the operation tongue piece 13 is picked and pulled upward as in the case of the first opening, the carton 100 is opened as shown in FIG.

  As described above, according to the carton 100 of the present embodiment, when the operation tongue 13 is pulled upward toward the upper side of the carton 100, first, in the width direction of the operation tongue 13 at a portion corresponding to the operation tongue 13. A part 20p of the second side plate 20 that is not attached to the inner folded piece 22 from the second side plate 20 along with the outer folded piece 12 is provided. It peels smoothly. Subsequently, when the operation tongue piece 13 is pulled up toward the upper side of the carton 100, the peeling pieces 80 whose both ends are cut from the surface side of the carton 100 to the middle in the thickness direction by the first cut lines 46 are the outer folded pieces 12. As a result, it is peeled off from the second side plate 20. That is, delamination of the paper constituting the second side plate 20 occurs in the second side plate 20 where both side ends are cut by the first cut line 46. The force required to cause delamination in the second side plate 20 is the force required to peel the two sheets of paper that are pasted to each other, and the cut line formed by the perforation having a bridge. It is weaker than the force required for Therefore, the second side plate 20 can be delaminated to the peeling pieces 78 and 80 by a relatively weak lifting force with respect to the operation tongue piece 13 and the outer folded piece 12. Therefore, the person who opens the carton 100 smoothly moves to the separation of the outer folded piece 12 without feeling instantaneous resistance when pulling up the operation tongue piece 13 and starting delamination of the second side plate 20. Can do. And the possibility of scattering the powder inside the carton 100 at the time of opening is wiped away.

  Further, according to the carton 100 of the present embodiment, the second side plate 20 that is delaminated to the peeling pieces 78 and 80 is the carton until the operation tongue piece 13 is pulled upward toward the upper side of the carton 100 at the first opening. Since it is connected to the surrounding second side plate 20 from the inside to the middle in the thickness direction, the second side plate 20 that is delaminated when the paper panel 10 is boxed may be reversed and caught by a box making machine or the like. Therefore, the occurrence of a paper jam can be surely prevented. Furthermore, the first cut line 46 may be formed from the surface side of the carton 100 to the middle in the thickness direction, taking care that the paper panel 10 does not penetrate, and there is a slight difference in the cut depth for each paper panel 10. However, the above-described effects are maintained. Therefore, it is possible to improve the ease of boxing and production efficiency of the carton 100 without requiring special control or the like when forming the first score line 46.

  Further, according to the carton 100 of the present embodiment, the portion 20p of the second side plate 20 that includes the cut portion 44 in the portion corresponding to the operation tongue piece 13 and is not attached to the inner folded piece 22 is the first portion 20p. Since the second cut line 50 is included, when the operation tongue piece 13 is pulled up toward the upper side of the carton 100, the part 20p of the second side plate 20 can be more easily and outwardly folded by the weak lifting force. As a result, it is peeled off from the second side plate 20.

  Moreover, according to the carton 100 of this embodiment, even if the width | variety of the operation tongue piece 13 is smaller than the width | variety of 1st cutting parts 32 (refer FIG. 7), the operation tongue piece 13 is the upper direction of the carton 100. The width of the peeled portion separated from the second side plate 20 is continuously expanded as it is pulled upward. As a result, the peeled portion is smoothly cut off from the second side plate 20, and the unsealed person has a lid 82 formed of the center portion of the top plate 14 between the first cut portions 32 and the end portions on both sides of the top plate 14. It is possible to smoothly shift to separation.

  Further, according to the carton 100 of the present embodiment, the operation tongue piece 13 is inserted from the cut portion 44 of the second side plate 20 into the second side plate 20 and the inner folded piece 22 surrounded by the cut portions 44 and 45. It can be easily resealed by inserting it into the space between the mouth forming part 54. Further, the operation tongue piece 13 is sandwiched between the second side plate 20 and the inner folded piece 22, and a part 20p of the second side plate 20 is locked to the peeling piece 78, whereby the operation tongue piece 13 and the outer side piece The folded piece 12 is securely fixed to the surface side of the second side plate 20, and sufficient resealability is obtained.

  The embodiment to which the present invention is applied has been described above. However, it is possible to appropriately replace the components in the above embodiment with known components without departing from the spirit of the present invention.
