A method for attaching a hand-carrying portion of a bag, the method comprising the steps of:
- joining an inner side hand-carrying member and an outer side hand-carrying member such that an interval between one end of the inner side hand-carrying member and one end of the outer side hand-carrying member is equal to an interval between another end of the inner side hand-carrying member and another end of the outer side hand-carrying member, the inner side hand-carrying member being a long, band-shaped body, and the outer side hand-carrying member being a long, band-shaped body having a wider width than the inner side hand-carrying member, the outer side hand-carrying member and the inner side hand-carrying member having different lengths, such that the outer side hand-carrying member is longer than the inner side hand-carrying member;
- curving the inner side hand-carrying member and the outer side hand-carrying member, which is joined to the outer side of the inner side hand-carrying member, to a U-shape in front view in a joining region including the hand-carrying region, the inner side hand-carrying member and the outer side hand-carrying member being curved in a width direction of the inner side hand-carrying member and the outer side hand-carrying member, the inner side hand-carrying member having a non-joining region, which is not sewn or joined to the outer side hand-carrying member, the non-joining region being a flat portion of the long, band-shaped body that forms the inner side hand-carrying member;
- sewing a vicinity of a longitudinal end edge of the outer side hand-carrying member and a vicinity of a longitudinal end edge of the inner side hand-carrying member together in the joining region where the outer side hand-carrying member and the inner side hand-carrying member are joined to form a sewing portion, such that
- the outer side hand-carrying member is folded around the inner side hand-carrying member to form an overlapped region centered between the one end of the inner side hand-carrying member and the another end of the inner side hand-carrying member, and centered between the one end of the outer side hand-carrying member and the another end of the outer side hand-carrying member, and
- the sewing portion is formed in the overlapped region;
- attaching back surfaces of the one end of the inner side hand-carrying member and the other end of the inner side hand-carrying member to an outer surface of the bag main body to form one attachment portion at the one end of the inner side hand-carrying member and another attachment portion at the another end of the inner side hand-carrying member, such that
- the one end and the other end of the inner side hand-carrying member rest flat against the outer surface of the bag main body, and
- the sewing portion extends to a vicinity of the one end of the inner side hand-carrying member and a vicinity of the another end of the inner side hand-carrying member, such that a space exists between the sewing portion and the one attachment portion, and a space exists between the sewing portion and the another attachment portion;
- and
- attaching back surfaces of the one end and the other end of the outer side hand-carrying member to the outer side of the bag main body to form one lower attachment portion and another lower attachment portion, such that the one end and the other end of the outer side hand-carrying member rest flat against the outer surface of the of the bag main body,
- wherein attaching the back surfaces of the one end and the other end of the outer side hand-carrying member to the outer side of the bag main body includes forming a sandwiching portion for sandwiching an article in a space between an inner side of the outer side hand-carrying member and the outer surface of the bag main body in the non-joining region, such that
- the non-joining region of the outer side hand-carrying member is formed in the extended region of the outer side hand-carrying member, or in a non-sewing region extended from the hand-carrying region, and
- the one lower attachment portion and the another lower attachment portion each include a flat portion of the outer side hand-carrying member brought into contact with, and sewn to, the outer surface of the bag main body.
