It consists of a bottom wall (15) that is installed, and the lateral center of the left and right side walls (13) and (14) can be bent inward along the vertical direction so that it can be folded flat. ing. In addition, the periphery of the upper end of the bag body (1) is folded inward to form the bag mouth (3), and inside the folded portion (16), the front and rear walls (11) and (12) are almost widthwise. Two reinforcing sheets (4) and (5) are arranged in an interpositioned state over the whole.

The reinforcing sheets (4) and (5) serve to prevent breakage of the peripheral portion of the bag mouth and the connecting portion of the strap (2), and in this embodiment, are made of cardboard or cardboard. As shown in FIG. 2, the upper end of the bag mouth (3) is exactly inserted to the inside of the upper edge of the bag mouth (3), and the lower end thereof projects below the lower end of the folding part (16). Then, of the abutting portions of the folded portions (16) and the reinforcing sheets (4) and (5), the portions near the upper end are joined and connected to each other via the adhesive layer (6).

And, as shown in FIG. 5, the one reinforcing sheet (4) is cut so that its lower edge portion is continuously narrowed from both sides in the longitudinal direction toward the central portion. A downwardly projecting insertion piece (41) is formed in the central portion. The other reinforcing sheet (5) is provided with a slit-shaped notch (51) corresponding to the insert piece (41) at a position slightly lower than the center in the length direction. The insertion piece (41) and the cutout portion (51) constitute a means for closing the bag mouth (3), and the cutout portion (51) is formed to be slightly longer than the length of the insertion piece (41). And insert piece (41)
The both ends are formed in an arc shape in order to facilitate insertion into the notch (51).

Further, as shown in FIG. 1, string passing holes (7) and (7) are formed at both upper ends of the bag body (1). These string through holes (7) (7) are such that the folded portions of the left and right side walls (13, 14) are folded inward in the lateral center of the left and right side walls (13), (14) in the folded state and the front wall (11). ) To a rear wall (12). Then, each end of the strap (2) is attached to the rear wall through each strap passage hole (7).
It is inserted from (12) to the front wall (11), and a knot (8) for retaining is formed at the insertion end so that the strap (2) cannot be removed from the bag body (1) and can be removed. It is installed as possible.

In the shoulder bag (A), after the bag body (1) is opened in a tubular shape to accommodate an object to be accommodated, as shown in FIGS. 3 and 4, one reinforcing sheet (4) is inserted.
