The side surface portion 42B for folding and the belt-like gripping portion 50B are brought into contact with the surface of the other side surface portion 42 and the belt-like gripping portion 50, and the corner portion is curved on the side surface portion 42A side by the bending elasticity of cardboard. The front intrusion surface 42b is brought into contact with the surface of the front surface portion 41 so that the entire contact surface is adhered, and then the bottom surface portion 60 is sandwiched between the fin portions 42c as described above. As shown in FIG. 5, the container is assembled into a container having a curved corner portion whose upper opening portion is open and whose lateral width gradually widens upward. As seen from the side, the belt portion 51 having the belt side surface portions 52 provided on both sides thereof rises narrower than the side surface portions 42 to 42B in the entire lateral direction, and the top surface proximal end folds. 47 enters the curved corner portion in an arc shape, gradually becomes substantially linear, and continuously rises to the belt folding fold 53 in the same linear shape.

  When closing the upper opening, the front top surface portion 43 and the rear top surface portion 43A are bent to the middle position in the front-rear direction with the arc-shaped top surface base end fold 47 as a fulcrum, and the top top edge 48 is They are brought into contact with each other to form a mountain-shaped closed state. At that time, the higher stepped side of the top surface upper edge 48 is engaged with the notch 49, and the opponent with the lower step is abutted from below. In conjunction with this closed folding, the area adjacent to this fold of the top surface connecting portions 56 to 56B via the top surface side end fold 45 is integrated with the belt side surface portion 52 and the front side top surface portion 43. The rear side top surface portion 43 </ b> A is valley-folded, and the belt portion 51 is folded into the mountain via the belt folding fold 53. In this process, front and rear oblique top surface side end folds 45 on both sides are tilted in the horizontal direction by folding the belt side surface portion 52 so as to make the descending slope shallower while approaching each other. The belt portion 51 also bends toward the front top surface portion 43 and the rear top surface portion 43A so that they can be connected together. In other words, the folded belt side surface portion 52 is bent upward with respect to the top surface upper edge 48 integrally with the belt portion 51, with the top surface side end fold 45 changing the inclination angle as a fold. Between the front and rear top surface side end folds 45, the top surface connecting portions 56 to 56B in a small area adjacent to the top surface side end fold 45 shortened by the arc shape of the top surface base end fold 47.

The narrow belt portion 51 and the belt side surface portion 52 are horizontally inserted on the wide side, so that the top edge 48 of the top surface rises in an arc shape. The used grip opening 40a is formed. Moreover, a connection state is fixed by making the other party adhere | attach the double-sided tape 59 (FIG. 5) previously adhered to one wide belt part 51. FIG. As a result, a belt-like grip feel is obtained, and not only the strength against product load is improved by the two-piece stacking on the container body, but also an excellent appearance with a curved surface and a curved surface is exhibited. The front entry surface 42b appears on the front surface portion 41, and a more unique design effect can be obtained by the side edges of the inclined curve.

  The top surface base end crease 47 excluding the top surface upper edge 48 and both side portions has a semicircular shape with the same curvature, but various modifications are conceivable. For example, the top surface base end fold may be a non-circular curve, and the top surface upper edge may be a curved line having a vertical width that can form a mountain shape instead of the shift shape. Further, the folds at the top base end and the top top edge can be formed in a rectangular parallelepiped container whose corner is not curved. For example, in the rectangular parallelepiped container shown in FIG. 2 described above, the top surface base end fold 17 is formed in a concave or convex curve, and the top surface upper edge 48 has a vertical width of the top surface that is half the front-back width of the container. However, it can also be curved over the entire area without becoming narrow.

The belt is provided with a belt side face 82 and a belt part 81 that are respectively raised with the same lateral width with belt folding folds 83 interposed therebetween, and are formed in the same plane above the side faces 72 and 72A. The belt folding fold 83 is an inclined straight line extending from both sides of the base end of the belt portion 81 to the base end of the top surface side end fold 75 so as to be interposed in front of and behind the top surface connecting portions 86 and 86A on both sides. It is extended to the shape. The front and rear upper end edges 87 of these top surface connecting portions extend linearly downward from the side end of the top surface upper end edge 78, and the belt side base end folding of the base end of the belt side surface portion 82 on the extended line. An eye 88 is formed, and is further continuous with a horizontal belt base end fold 89 formed at the base end of the belt portion 81. These belt-shaped gripping portions are formed symmetrically with respect to the longitudinal symmetry axis except for the sticking piece 79 and are plane-symmetrical. However, the lateral width of the belt portion 81 of the side surface portion 72A is smaller than that of the counterpart. It is formed slightly wider.

  Accordingly, when the closed folding from the opened assembly state shown in FIG. 8 is performed, the front top surface portion 73 and the rear top surface portion 13A are bent at right angles to the front and rear with the top surface base end fold 77 as a fulcrum. In conjunction with each other, the top surface connecting portions 86 and 86A are valley-folded at right angles to the front top surface portion 73 and the rear top surface portion 73A via the top surface side end folds 75 on both sides. The folds are folded through the inclined area of the belt folding fold 83 and folded into the same plane as the side surfaces 72 and 72A. In this process, the belt side base end fold 88 is bent into a vertical surface along the side surface portion 72 and the side surface portion 72A, and the belt side surface portion 82 is bent at a right angle in the horizontal direction following this. In conjunction with this, the belt portion 81 is also integrally bent at a belt base end fold 89 at a right angle. At this time, the inclined upper edge 87 and the belt side base end crease 88 continuous thereto become inclined lines that gradually separate from each other in the front-rear direction as they rise in the vertical plane, respectively, The part 82 is folded along this inclined line. The folding angle of the belt side surface portion 82 can be further bent and folded to the belt portion 81 in the distal region.

  Such a development plate is assembled as follows. The front part 71, the rear part 11A, the side part 72, the crease 74 between the side parts 72A, the straight front side top part 73, and the top side end crease 75 of the rear side top part 73A are perpendicular to each other in order. As shown in FIG. 8, the adhesive piece 79 is bent at a right angle and attached to the inside of the rear surface portion 71A and the rear top surface portion 73A, and then the bottom surface portion 90 is assembled as described above. Assembling in a rectangular parallelepiped shape with the upper opening opened.

  In this state, the upper opening between the front and rear top surface proximal end folds 77 is closed as follows. The front top surface portion 73 and the rear top surface portion 73A are bent at right angles to the middle position in the front-rear direction using the top surface base end fold 77 as a fulcrum, and horizontally closed when the top surface upper edge 78 is in contact with each other. Let In conjunction with this folding, the top surface connecting portions 86 and 86A are valley-folded at the top surface side end folds 75 with respect to the front top surface portion 73 and the rear top surface portion 73A, and are folded for belt folding. It is folded into a vertical plane through the inclined area of the eye 83 and folded. In this process, the inclined upper end edge 87 of the top surface connecting portions 86, 86A and the belt side base end fold line 88 linearly connected to the upper end edge 87 are formed on the front top surface portion in the vertical plane orthogonal to the horizontal closing surface. On the 73 side, straight lines are formed in a direction away from each other toward the front, and on the rear top surface portion 73A side toward the rear gradually upward. As a result, the belt side surface portions 82 on both sides are folded at a right angle with respect to the top surface connecting portions 86 and 86A along the straight line, and the belt portion 81 and the belt base end fold 89 are integrated therewith. At a right angle and bent horizontally. Accordingly, in the assembled state shown in FIG. 9, the top surface connecting portions 86 and 86A on both sides protrude upward at a right angle with respect to the front side top surface portion 73 and the rear side top surface portion 73A in the horizontal closed position, and the belt portion. 81, a square-shaped gripping opening 70a is formed.

  FIG. 10 shows a modification of the hand-held container according to FIGS. 4 to 6, and the same parts will be described with the same reference numerals. The belt portions 51 are not directly connected to each other but are connected via a known synthetic resin handle 95. Engagement pieces 95a are formed on both sides of the handle so as to be folded back so as to exhibit bending elasticity from the contact state with the main body. On the other hand, the gripping belt portions 50, 50A, 50B are deformed so that the lateral width of one belt side surface 52 is the same as the lateral width of the belt portion 51 in the tip region so as not to interfere during assembly. An engaging hole 96 for engaging two sheets in a stacked manner is formed. This perforation can also be performed in a state where the front end regions of both belt side surfaces 52 are overlapped, and it is also possible to fold from the front end side to make multiple sheets. In short, since the hand-held portion is belt-shaped, the engagement hole can be easily formed, and the strength of the engagement hole is secured by folding the belt side surface portion 52.
