FIG. 1C is a perspective view of the box-shaped container 1A as viewed obliquely from the rear, and FIG. 1D is a bottom view of the box-shaped container 1A. FIG. 2 is a plan view of an example of a blank sheet 2A of the container body 10A of the box-shaped container 1A.

  This box-shaped container 1A includes a container body 10A having an upper surface opened and a lid body 30 that can cover the opening surface of the container body 10A.

  The container body 10A includes a rectangular front wall 11, a back wall 12 having the same width as the front wall 11, a pair of first side walls 13A and 13B continuous to the left and right sides of the front wall 11, and the left and right sides of the back wall 12. It has a pair of second side walls 14A and 14B continuous to the side and a pair of third side walls 15A and 15B sandwiched between the first side wall and the second side wall, and a fold line is formed between these walls. Yes.

_A fold line B1A between the first side wall 13A and the third side wall 15A continuous to the left side of the front wall 11 is convexly curved toward the third side wall 15A, and between the second side wall 14A and the third side wall 15A. polygonal line B2 _a is also curved convexly in the third side wall 15A side. As shown in the blank sheet 2A in FIG. 2, the first side wall 13A, the second side wall 14A, and the third side wall 15A are separated by broken lines B1 _A and B2 _{A in} which a rectangular region of a flat sheet is curved. It has become.

Fold lines B1 _A between the first side wall 13A and the third side wall 15A overlaps the upper end and the left side edge of the front wall 11, preferably overlaps the upper left corner of the front wall 11, the lower end of該折line B1 _A frontal It is located away from the left side of the wall 11. Further, line B2 _A between the second side wall 14A and the third side wall 15A overlaps the upper end and the right side edge of the rear wall 12, preferably overlaps the upper right corner of the rear wall 12, the lower end of該折line B2 _A Is located away from the right side of the back wall 12. These two broken lines B1 _A and B2 _A do not cross each other. By providing the fold lines B1 _A and B2 _A in this manner, the container body 10A has a rectangular opening on the top surface, but the bottom surface 16 has an octagonal shape, and the front wall 11 and the back wall on the top surface of the container body 10A. 12 is larger than the distance between the front wall 11 and the back wall 12 on the bottom surface 16 of the container main body 10A. That is, the apparent shape of the side surface of the container main body 10A is a reverse letter C (that is, a reverse taper shape). Therefore, when the container body 10A is gripped from the side surface, the container body is easily gripped, and the container body 10A is less likely to slip from the hand.

With respect to the extent to which the above-mentioned fold lines B1 _A and B2 _A are convexly curved toward the third side wall 15A and the extent to which the fold lines B1 _B and B2 _B are convexly curved toward the third side wall 15B, When the width of the first side walls 13A, 13B is W1, the width of the second side walls 14A, 14B is W2, and the width of the third side walls 15A, 15B is W3 at half height, W2≥W1≥W3 Preferably, W2>W1> W3. This is because the first side walls 13A and 13B preferably have a width that allows the base of the thumb to be as wide as possible, and the second side walls 14A and 14B are as wide as possible from the base of the index finger, middle finger, ring finger, and little finger to the second joint. It preferably has a touching length. Thereby, the grip property at the time of grasping container body 10A by hand improves. Furthermore, the gripping property of the container body 10A when the carton is gripped by the abdominal surface of each finger is also improved by applying an inverse taper to the apparent side surface shape of the container body 10A.

Further, the folding lines B1 _A and B2 _A may be formed so that the maximum width of the first side wall 13A and the maximum width of the second side wall 14A are located at 1/2 to 1/4 of the height of the container body 10. preferable. The distance D2 between the lower end of the fold line B2 _A and the rear wall 12, is preferably larger than the distance D1 between the lower end and the front wall 11 of the fold line B1 _A.

The first side wall 13B, the third side wall 15B, and the second side wall 14B that are continuous to the right side of the front wall 11 are the target with the first side wall 13A, the third side wall 15A, the second side wall 14A, and the front wall 11 interposed therebetween. A bent line B1 _B is formed between the first side wall 13B and the third side wall 15B, and the third side wall 15B is formed between the second side wall 14B and the third side wall 15B. A bent line B2 _B curved to the side is formed.

By forming the fold lines B1 _A , B2 _A , B1 _B , and B2 _B in this way, the side surface of the container body 10A formed by the first side wall 13A, the second side wall 14A, and the third side wall 15A is the same as that of the container body 10A. The container body 10A protrudes laterally (that is, in the width direction of the front wall 11), and the side surface of the container main body 10A formed by the first side wall 13B, the second side wall 14B, and the third side wall 15B also protrudes to the side of the container main body 10A. Therefore, when the container main body 10A is gripped from the side, the palm and fingers that grip the container main body 10A can be brought into contact with the container main body 10A in a larger area than when gripping the rectangular parallelepiped container carrier. It becomes easy to securely hold the main body 10A. In particular, as described above, when W2 ≧ W1 ≧ W3, more preferably W2>W1> W3, the palm and fingers that hold the container body 10A can be brought into contact with the container body 10A over a wide area. It becomes. Further, the container body 10A can be easily gripped by the fact that the apparent side surface shape of the container body 10A is an inversely tapered shape. Therefore, for example, even when the container body 10A has the size of a general powder detergent box container, and the container body 10A contains about 2.5 kg of contents, a general consumer The container body 10A can be easily held with one hand. Further, even when the box-shaped container 1A is used in a high humidity environment, the container body 10A can be easily gripped.

Note that the curved bent lines B1 _A , B2 _A , B1 _B , and B2 _B described above can be formed from arcs, elliptical arcs, and the like.

Further, in the blank sheet 2A shown in FIG. 2, in the back wall 12, the distance between both ends of the lower side and the upper side is shorter than the distance between the central part of the lower side and the upper side. Note that the distance between the central portion of the lower side and the upper side of the back wall 12 is equal to the distance between the lower side and the upper side of the front wall 11.
Further, in the blank sheet 2A, both end portions of the lower side of the back wall 12 and the vicinity 12x thereof are arc-shaped, and the lower side of the back wall 12 is curved downward and convex. Correspondingly, in the container main body 10A, the lower side of the back wall 12 is convexly curved inside the container main body 10A (FIGS. 1C and 1D). By curving the lower side of the back wall 12 in this way, it becomes easier to hold the back wall 12 with a finger when the container body 10A is gripped from the side, and the ease of gripping the container body 10A is further improved.

  On the other hand, the lid 30 is formed in a flat box shape that can cover the opening surface of the container body 10A. As described above, the container body 10A protrudes sideways and has an octagonal bottom surface. However, since the upper surface is a quadrangular shape, the lid 30 is similar to the lid of a conventional rectangular parallelepiped box-shaped container. Moreover, it can be set as the flat rectangular parallelepiped box shape.

  In order to lock the lid body 30 to the container main body 10A, the front wall 31 of the lid body 30 has a lower central portion protruding downward, and a locking piece is formed by a notch 32 at the base of the protruding portion.
