And a pair of side surfaces 13 along the longitudinal direction LD and a pair of side surfaces 14 along the width direction WD. For example, the container body 10 has dimensions of about 45 mm to 55 mm in height, 140 to 160 mm in width, and about 230 to 250 mm in length.

  As shown in FIG. 3, the container body 10 includes an opening 15 formed by breaking a perforation 20 described below, and a double door 16. The container body 10 is a container that accommodates a sheet body 9 such as kitchen paper, for example, and is made of cardboard.

  The perforation portion 20 is formed by alternately arranging a plurality of cut portions 21 and a plurality of non-cut portions 22 on the top surface 11 of the container body 10. The plurality of notches 21 are formed by slits that pass through members (thick paper) constituting the container body 10.

In the present embodiment, the perforation 20 includes an opening perforation 210 and a hinge perforation 220.
The opening perforation 210 is formed inside the top surface short edge 11 a along the width direction WD of the top surface 11. The opening perforation part 210 has a pair of short side edges 210a formed along the width direction WD and an opening edge 210b that connects the pair of short side edges 210a at a substantially central part in the width direction WD. The opening perforation part 210 forms two lid parts 16 that can be opened in two-folds by breaking the pair of short side edges 210a and the opening edge 210b. And the opening part 15 is formed when the two cover parts 16 are opened.

  The length of the plurality of cut portions 21 in the opening perforation 210 is preferably 2 mm to 10 mm. Further, the lengths of the plurality of non-cut portions 22 are formed shorter than the length of the cut portions 21 from the viewpoint of easily opening the opening perforation portion 210. The length of the non-cut portion 22 is preferably 0.1 mm to 2 mm.

  In addition, the perforation part 210 for opening has the fracture | rupture prevention notch part 50 in each edge part (near the four corners of the top | upper surface 11) of the short side edge 210a. The breakage prevention cut portion 50 is formed in a shape that extends in the direction in which the short side edge 210a extends and then bends and extends toward the top surface long edge 11b, and further has a tip bent in an arc shape toward the central portion side in the width direction WD. Has been.

  The hinge perforations 220 are formed along the longitudinal direction LD on one end side and the other end side of the top surface 11 in the width direction WD. The perforation part 220 for hinges becomes a starting point of bending when the perforation part 210 for opening is opened and the opening part 15 is formed. The total length of the perforation part 220 for hinges can illustrate 200 mm-230 mm, for example.

  The perforation portion 220 for the hinge includes a first cut portion 221, a second cut portion 222, a third cut portion 223 as the cut portion 21, and a hinge non-cut portion as the non-cut portion 22. 224.

  The first notch portion 221 is disposed substantially at the center in the longitudinal direction LD of the hinge perforation portion 220 and has a curved shape so as to protrude toward the center portion (inner side) of the top surface 11 in the width direction WD. Have. The first cut portion 221 is formed to have the longest length among the plurality of cut portions 21. The linear distance between both end portions of the first cut portion 221 is preferably in the range of 1/8 to 1/6 of the length of the perforation portion 220 for the hinge. When the length of the 1st notch part 221 is too long, the 1st notch part 221 will become easy to open and it is unpreferable in terms of hygiene. If the length of the first cut portion 221 is too short, the force for bending the lid portion 16 cannot be sufficiently reduced. The linear distance between the both ends of the 1st notch part 221 can illustrate 25 mm-35 mm.

  A plurality of the second notches 222 are arranged along the longitudinal direction LD of the hinge perforation 220 and extend linearly. The length of each of the second notches 222 is preferably 5 mm to 15 mm from the viewpoint that the lid 16 can be easily bent with the hinge perforation 220 as a starting point of bending.

  The third notches 223 are disposed on both ends of the first notches 221 between the first notches 221 and the second notches 222, respectively. The third cut portion 223 is disposed adjacent to the first cut portion 221 and is curved and formed so as to be convex in the direction opposite to the first cut portion 221, that is, outward in the width direction WD. Is done. The third cut portion 223 is formed shorter than the first cut portion 221. The linear distance between both end portions of each third cut portion 223 is configured to be approximately equal to the length of the second cut portion 222.

  The hinge non-cut portion 224 is formed longer than the non-cut portion 22 constituting the opening perforation portion 210 from the viewpoint of preventing the hinge perforation portion 220 from being easily broken. The Each length of the non-cutting part 224 for hinges is preferably 2 mm to 5 mm.

  The fracture preventing slit 30 is formed in the first cut portion 221 and extends in a direction crossing the extending direction of the first cut portion 221. Specifically, the breakage preventing slit 30 is formed at the center in the longitudinal direction of the arc constituting the first cut portion 221 so as to extend toward the width direction WD of the top surface 11. The breakage preventing slit 30 is a cut that penetrates the members constituting the container body 10. It is preferable that the breakage preventing slit 30 has a length of 1/3 to 1/2 with respect to the distance between the end portions in the longitudinal direction of the first cut portion 221. The breakage preventing slit 30 has a length of about 8 mm to 12 mm, for example, and has a length of about 1/3 with respect to a distance 25 mm to 35 mm between the end portions in the longitudinal direction of the first cut portion 221. doing.

  The auxiliary breakage prevention slit 40 is arranged in the vicinity of the breakage prevention slit 30 and spaced from the cut portion 21. In the present embodiment, two auxiliary breakage prevention slits 40 are formed between the perforation portion 220 for the hinge and the top surface long edge 11 b extending in the longitudinal direction LD of the top surface 11. Each of the auxiliary fracture preventing slits 40 has one end disposed on both ends of the first cut portion 221, and the other ends extend obliquely so as to approach each other on the top long edge 11 b side of the top surface 11. Specifically, as shown in FIG. 2, each of the auxiliary breakage prevention slits 40 extends from the intersection of the first cut portion 221 and the breakage prevention slit 30 toward the top long edge 11 b side. The first imaginary line 41 is formed on the second imaginary line 42 extending from the vicinity of the end in the longitudinal direction of the first notch 221 toward the first imaginary line 41. The auxiliary breakage prevention slits 40 each have a length of, for example, 5 mm to 10 mm, and the distance between the end portions on the top long edge 11b side in the two auxiliary breakage prevention slits 40 is 10 m to 15 mm apart. Can be exemplified.

The state of use of the packaging container 1 will be described with reference to FIG.
Inside the packaging container 1, for example, a thick paper sheet body 9 such as kitchen paper is folded in two and accommodated alternately. An opening 15 for taking out the sheet body 9 is provided in the top surface 11. Since the kitchen paper is thick and has a large area, the perforated portion 20 (perforated perforated portion 210) is large (a pair of short side edges 210a and opening edges 210b) so that the opening 15 is formed large. Is formed.

Further, since the opening 15 is formed larger, the size of the lid 16 is also increased. In order to be able to bend such a large lid part 16 easily, the hinge part which becomes the starting point of the folding of the lid part 16 is also comprised by the perforation part 20 (perforation part 220 for hinges).
Moreover, since the overlapped sheet body 9 approaches the bottom surface 12 side of the packaging container 1 by gravity, a space is formed between the sheet body 9 stacked on the top and the top surface 11. For this reason, the top surface 11 is in a state of being easily recessed when pressed.

For example, a plurality of packaging containers 1 are packed in a cardboard box or the like (not shown) and delivered to a store or the like. The store clerk takes out the packaging container 1 from the cardboard box and displays it on the store shelf or the like. At this time, the clerk often grips the substantially central portion of the packaging container 1 in the longitudinal direction.
In addition, a consumer who holds the displayed product may exert a great force on the perforation 20 when holding the packaging container 1 or during transportation after purchase.

  Here, in the present embodiment, a direction intersecting the extending direction of the first notch 221 with the first notch 221 disposed at a position where the force is most easily applied when the box-shaped packaging container 1 is gripped. An anti-breaking slit 30 extending in the direction is formed. As a result, as shown in FIG. 4, when the vicinity of the first cut portion 221 is pushed from above, the pushed force A is applied to the non-cut portion 22 (hinge non-cut portion 224) side. It can be difficult to convey.

Moreover, the length of the 1st notch part 221 is comprised longer than the other notch parts 21 (the 2nd notch part 222 and the 3rd notch part 223), and the width direction center side of the top surface 11 is comprised. It is curved and formed so as to become convex. For this reason, when the vicinity of the first cut portion 221 is pressed with a finger, the top surface 11 moves so as to sink downward (toward the sheet body 9 accommodated in the packaging container), but the first cut portion 221 Since it is formed longer than the other incision parts 21, even if the top surface 11 is pressed deeply, it is difficult for the pressing force to reach the adjacent non-incision parts 22 (hinge non-incision parts 224).
As described above, according to the present embodiment, the force A that pushes the top surface 11 downward can be absorbed in the vicinity of the first cut portion 221, so that the adjacent non-cut portions 22 are not easily cut.

  Further, an auxiliary breakage prevention slit 40 formed in a square shape is formed on the top long edge 11b side of the breakage prevention slit 30. Thereby, when the vicinity of the 1st notch part 221 is pushed, it can be made difficult to transmit the pushed force A to the non-notch part 22 (non-notch part 224 for hinges) side.

  According to the packaging container 1 of this embodiment demonstrated above, there exist the following effects.

  (1) The packaging container 1 is formed into a container body 10, a perforation portion 20 formed by alternately arranging a plurality of cut portions 21 and a plurality of non-cut portions 22, and at least one cut portion 21. And a breakage preventing slit 30 that extends in a direction that intersects with the direction in which the cut portion 21 extends. Thereby, in the packaging container 1 in which the perforation is formed, even if a pressing force is applied strongly, the fracture preventing slit 30 is formed in the direction intersecting the notch 21 in the perforation 20, The cut portion 21 can be easily opened. Therefore, since the pressed force can be hardly transmitted to the non-cutting portion 22 side adjacent to the cutting portion 21, unintentional breakage of the perforation portion 20 is prevented.

  (2) The container body 10 is formed in a box shape having the top surface 11, the perforation portion 20 is disposed on the top surface 11, and an opening perforation portion 210 that forms an opening portion by breaking is formed. When the part 15 is formed, it includes a hinge perforation part 220 that becomes a starting point of bending. As a result, when the opening perforation 210 is broken to form the opening 15, the opening perforation 210 is opened because the hinge perforation 220 is also formed in the portion constituting the hinge. Thus, it becomes easy to lift a part (the lid portion 16) of the separated top surface 11. Therefore, opening becomes easy, and it becomes easy to maintain the opened shape after opening.

  (3) Moreover, the break prevention slit 30 was formed in the cut portion 21 constituting the perforation portion 220 for the hinge. Thereby, since the breakage preventing slit 30 is formed in the cut portion 21 constituting the hinge perforation portion 220, unintended perforation breakage in the hinge perforation portion 220 is prevented. Moreover, since the break prevention slit 30 is formed in the perforation part 20 (hinge perforation part 220) formed in the top | upper surface 11 of the packaging container 1, the box-shaped container main body 10 is grasped with a strong force from the top. Even in this case, the breakage of the hinge perforation 220 is prevented.

  (4) The container body 10 is formed of a rectangular parallelepiped having a width and length larger than the height, and the hinge perforation 220 is formed to extend in the longitudinal direction LD on one end side of the top surface 11 in the width direction WD. The break prevention slit 30 was formed in the cut portion 21 located at the center portion in the longitudinal direction LD of the perforation portion 220 for the hinge. As a result, when the flat box-shaped packaging container 1 is grasped by hand, the perforation portion 20 of the hinge perforation portion 220 disposed at the center portion of the longitudinal direction LD that is most easily gripped and broken. Unintentional breakage is prevented.

  (5) The hinge perforation 220 is arranged at the center in the longitudinal direction LD with the first notch 221 and a plurality of second notches 222 shorter than the first notch 221. The first cut portion 221 is formed in a curved shape that is convex toward the inside of the container body 10. Thereby, within the predetermined range which arrange | positions the 1st cutting part 221, the length of cutting itself can be taken longer. Moreover, since it curves in the width direction of the top surface 11 from the edge part of the 1st notch part 221, when the top surface 11 is pushed down, it is easy to open below, and the force concerning the 1st notch part 221 is disperse | distributed. Easy to make.

  (6) The perforation portion 220 for the hinge further includes a pair of third cut portions arranged adjacent to the first cut portion 221, and the third cut portion 223 is formed by the first cut portion. It was arranged adjacent to the part 221 and formed in a curved shape so as to be convex in the opposite direction to the first cut part 221. As a result, the same effect as the above (5) can be obtained, and the force applied over a wider range can be dispersed.

  (7) In the vicinity of the rupture prevention slit, a plurality of auxiliary rupture prevention slits 40 arranged to be separated from the cut portion 21 are further included. Thereby, when the vicinity of the 1st notch part 221 is pushed, it can be made difficult to transmit the pushed force A to the non-notch part 22 (non-notch part 224 for hinges) side.

As mentioned above, although preferable embodiment of the packaging container 1 of this invention was described, this invention is not restrict | limited to embodiment mentioned above and can change suitably.
For example, the breakage preventing slit 30 is formed only in the first cut portion 221, but is not limited thereto. You may form so that the other notch part 21 may be crossed, and multiple may be formed.

  Moreover, although the 1st notch part 221 and the 3rd notch part 223 are demonstrated as what has the shape curved in the arc shape, if the force which presses the top | upper surface 11 can be disperse | distributed, it is an ellipse or a triangle. It may be present or may be linear.

  In the above embodiment, the lid portion 16 is described as a double-spreading lid portion. However, a single lid having a hinge formed on one side may be used.

  Moreover, in the said embodiment, although demonstrated as a cut | perforation which penetrated the perforation, the half cut line in which the cut was formed to the middle of the thickness direction may be sufficient, and the combination of the cut | interruption penetrated and a half cut line It may be.

  Moreover, in the said embodiment, although demonstrated as what accommodated the kitchen paper in the inside of the packaging container 1, if it is a sheet | seat body, it will not be restricted to this, Paper or a nonwoven fabric of other uses, a product made from resin, A laminated storage bag may be accommodated.
