[Embodiment of the invention]

 An embodiment of the present invention will be described below. FIG. 1 is an exploded view of a paper sheet 10 constituting the box of the present invention. The paper sheet 10 is made of cardboard or the like, and has a shape obtained by cutting off a region indicated by a two-dot line from one square. The thin solid lines are the fold lines, and if the surface shown in FIG. 1 is the inside surface of the box, all of the fold lines are folded in a valley. In the paper sheet 10, a portion constituting the bottom panel 14 of the main body 12 and a portion constituting the top panel 18 of the lid 16 are each formed of a congruent right-angled isosceles triangle. The bottom panel 14 and the top panel 18 are interconnected via a rectangular connection panel 20. One long side 22 of the connection panel 20 corresponds to the base of the right-angled isosceles triangle of the bottom panel 14. The other long side 24 of the connection panel 20 corresponds to the base of the right-angled isosceles triangle of the top panel 18.

To the equal sides 26 and 28 of the bottom panel 14, side wall panels 30 and 32 each having a substantially rectangular shape (more precisely, a trapezoidal shape because the angle α 1 is not a right angle) are connected. The angle α1 sandwiched between the sides 34, 36 forming the butted ends of the side wall panels 30, 32 forms a slightly acute angle. The folded short pieces 38 and 40 are connected to the sides 37 and 39 forming the other ends of the side wall panels 30 and 32, respectively. To the equilateral sides 42, 44 of the top panel 18, side walls panels 46, 48 each having a substantially rectangular shape (to be exact, trapezoidal because the angle α2 is not a right angle) are connected. The angle α2 sandwiched between the sides 50, 52 forming the butted ends of the side wall panels 46, 48 forms a slightly obtuse angle. In FIG. 1, the angles α1 and α2 are exaggerated, and the function of the present invention can be obtained even when the angles are closer to a right angle.

FIG. 2 shows that the side panels 30, 32 are bent along the folding lines (sides 26, 28) with respect to the bottom panel 14, and the sides 34, 36 constituting the butted ends of the side panels 30, 32 are bonded with adhesive tape. (Or, in the case of a box with thin paper bonded to the surface for the purpose of decoration, reinforcement, etc., the sides 34, 36 can be bonded together by bonding the thin paper.) The side panels 46, 48 are bent along the folding lines (sides 42, 44) with respect to the top panel 18, and the sides 50, 52 constituting the butted ends of the side panels 46, 48 are bonded together with an adhesive tape or a bonding tape. FIG. 3A shows a state in which the folded short pieces 38 and 40 are bent along bending lines 37 and 39 with respect to the side wall panels 30 and 32, respectively. 2 is a plan view, and FIG. 2B is a sectional view taken along the line AA in FIG. Since the angle α1 in FIG. 1 is configured to be slightly acute, the angle in FIG. 2B formed by the ridge line L1 formed by the butted ends of the side wall panels 30 and 32 of the main body 12 and the surface of the bottom panel 14. β1 is configured at a slightly obtuse angle. On the other hand, since the angle α2 in FIG. 1 is configured to be slightly obtuse, the ridge L2 formed by the butted ends of the side wall panels 46 and 48 of the lid 16 and the surface of the top panel 18 are formed. The angle β2 of 2 (b) is configured to be slightly acute. In FIG. 2, the angles β1 and β2 are exaggerated, and the function of the present invention can be obtained even when the angles are closer to a right angle.

An insole 56 shown in FIG. 3 is accommodated in the internal space 54 of the main body 12. 3 (a) is a plan view, and FIG. 3 (b) is a view on arrow B in FIG. 3 (a). The insole body 56 is made of cardboard or the like, and is connected to an insole panel 58 formed in the shape of a right-angled isosceles triangle equivalent to the bottom panel 14 and a base 60 of the right-angled isosceles triangle of the insole panel 58. The rear wall panel 62 is formed. The rear wall panel 62 is bent at a side 60 at right angles to the insole panel 58.

FIG. 4 shows a state where the insole body 56 is accommodated in the internal space 54 of the main body 12 and the main body 12 and the lid 16 are closed. 4A is a plan view, and FIG. 4B is a cross-sectional view of FIG. Since the angle β1 in FIG. 2B forms a slightly obtuse angle and the angle β2 forms a slightly acute angle, as shown in FIG. 4B, the ridge lines L1 and L2 are fitted well. Therefore, the closed state of the main body 12 and the lid 16 can be easily maintained. In particular, in this embodiment, the sides 64 and 66 forming the both end portions of the connection panel 20 are connected to any of the side wall panels 30 and 32 of the main body 12 and the side wall panels 46 and 48 of the lid 16. There is no restoring force (opening force) between the bottom panel 14 and the connecting panel 20 and between the top panel 18 and the connecting panel 20. 4B, the pressing force can be generated between the ridge lines L1 and L2, and the ridge lines L1 and L2 can be securely fitted. it can. From this state, by manually applying a force between the main body 12 and the lid 16 to slide the main body 12 and the lid 16 in a direction in which the ridges L1, L2 are separated from each other, the ridges L1, L2 The main body 12 and the lid 16 can be easily opened by removing the fitting.

FIG. 5 (side view) and FIG. 6 (perspective view) show a state where the main body 12 and the lid 16 are opened. At this time, a restoring force (a force for closing) is generated between the bottom panel 14 and the connecting panel 20 and between the top panel 18 and the connecting panel 20 (that is, a connecting force is generated between the bottom panel 14 and the connecting panel 20). The neutral positions of the main body 12 and the lid 16 due to the restoring force between the panel 20 and between the top panel 18 and the connection panel 20 are different from the closed position in FIG. The upper corner portions 68, 70 of the folded short pieces 38, 40 of the side wall panels 30, 32 of the main body portion 12 are positioned at the middle positions of the side wall panels 46, 48 of the lid body portion 16. The main body 12 and the lid 16 are kept open as shown in FIG. 5 and FIG. This open state can be suitably used for display of contents (commodities) in stores and the like.
