Abstract

PROBLEM TO BE SOLVED: To provide a pull-closing bag whose opening can be closed by pulling a string.SOLUTION: A bag 1 has at least front and rear walls 9 opposite to each other. String holes 3 for putting a string 2 therethrough are formed on the upper part of each wall 9. An end of the string 2 coming out of the string hole 3 on a front face is put through the string hole 3 on a rear face that is opposite to the string hole 3 on the front face, and is fixed at a stopper part 4. Grab areas 5 of the string 2 are pulled to close the opening 6 of the bag 1. A sub-hole 7 is formed adjacent to each string hole 3 so that the string 2 comes out of the sub-holes 7 to form the grab areas 5 at a position at which a user grabs the string 2 easily. The upper part of the bag 1 is folded to form a bag-folded part 8, where the string holes 3 are formed and the string 2 comes out of the sub-holes 7 to form the grab areas 5 outside the bag 1 at the position at which the user grabs the string 2 easily. Because the string holes 3 are located in the bag-folded part 8, passage areas 10 extended as a result of opening the bag 1 stay on the bag-folded part 8. The passage areas 10, therefore, do not hamper putting an article in or taking the same out of the bag 1.

FIG. 1 is a front perspective view of a main part, and a transparent region is indicated by a broken line. The shape of the bag body 1 is not limited, and has at least a side wall 9 facing the front and rear, and since the bottom plate is usually provided, the illustration of the bottom plate is omitted. The material of the bag 1 is not limited, and may be paper, woven fabric, non-woven fabric, leather, or artificial resin. The material of the string 2 is not limited, and a commercially available string is used, and even a twisted string can be used, but a braid is desirable because it rubs against the string hole 3. The bonding or bonding structure is not limited, and may be any one of adhesion, adhesion, welding, stitching, fitting, and the like. Since the nonwoven fabric is a representative material, the stitching will be described as a representative.

  Strings 2 of the same length and width are used in pairs, and stringing is performed with line symmetry in the front and rear. The middle region of the cord 2 is defined as the holding area 5, the ends of the two ends of the cord 2 are left and right as surface objects, and the end region of the cord 2 that has gone out from the string hole 3 is defined as the crossover area 10. The end of the transition area 10 is inserted into the other string hole 3 on the opposite shore across the opening 6, and a fastening part 4 is provided at the end of the insertion area, and the fastening part 4 is blocked by the string hole 3. Prevents you from going outside. The fastening portion 4 may be formed by tying the ends of the string 2, or by attaching a conventional product, a product name cantag. .

  The upper part of the bag body 1 is folded inward, the folded ridge portion is defined as a bag folded portion 8, and the region folded into the opening 6 and folded into the opening 6 is defined as a return band 11. It is desirable that the string hole 3 is on the line of the bag folding part 8. When the string hole 3 is on the line of the bag folding part 8, the holding area 5 is It is in a position that is difficult to pick because it is a structure that is hidden on the inner surface of the bag folding part 8, and a sub-hole 7 is provided next to the string hole 3, and the holding area 5 is taken out from the sub-hole 7, so that it can be easily picked.

  If the threading process of one string 2 is described, both ends having the central region 5 of the string 2 as an area 5 are passed from the outside to the front sub-hole 7 and out of the front string hole 3, and the front string hole 3 The crossing area 10 that has gone out from the outside is inserted into the string hole 3 on the opposite side of the back surface from the outside, and a fastening portion 4 is provided at the end of the insertion area to block the escape from the string hole 3. Also in the other string 2, the threading process is performed on the front and back surfaces.

  FIG. 2 is a side top perspective view of the open state. Since the present invention is bilaterally symmetric, no distinction is made between left and right. The string 2 has a long and narrow shape without a boundary, but a name is given to the region for the purpose of facilitating the description, and the length of the region can be freely changed. The central region of the string 2 is defined as a holding region 5, both sides of the holding region 5 are inserted into the sub-holes 7, are pulled out from the adjacent string holes 3 positioned at the insertion destination, and the protruding region is defined as a transition region 10. The tip of 10 is inserted into the other string hole 3 facing the opposite bank, and a fastening part 4 is provided at the tip of the inserted crossing area 10, and the fastening part 4 is clearly larger than the diameter of the string hole 3. Depending on the length of the distance, the end of the transition zone 10 is blocked and fixed.

  The fastening portion 4 is preferably formed by rounding the ends of the string 2 and using a cantag (trade name) which is a rod-like stopper, but may be stitched, bonded, or welded. The string hole 3 and the sub hole 7 are preferably provided by circular punching, but may be reinforced by eyelets, which may be made of metal or artificial resin. Since the crossover area 10 crosses the opening 6 to the opposite bank, the crossover area 10 is named as a crossover area. Since the bag body 1 has a bottom plate 12 and the bag body 1 itself has a conventionally known shape, the bottom plate 12 is not shown in the partial perspective view.

  FIG. 3 is a side top perspective view of the closed state. If the stroke in which the opening 6 is closed is described, both of the holding areas 5 are pulled out and the holding area 5 is pulled out from the auxiliary hole 7 to 10 is drawn into the cord hole 3 and shortens. As the crossing area 10 becomes shorter, the cord holes 3 on the opposite bank fixed by the fastening portion 4 approach each other, and the opening portion is opened by the approach between the cord holes 3. The 6 edges close together and close.

  FIG. 4 is a front perspective view in a closed state, in which the extended holding area 5 is hung on a elbow or shoulder as well as a handbag held by a hand. Since the base of the holding area 5 and the transition area 10 are provided in the bag folding part 8 which is the upper side of the side wall 9, the area of the side wall 9 is widened, and a picture, embroidery, etc. are applied to the wide side wall 9. Can improve aesthetics. Since the upper side of the side wall 9 is folded by the bag folding portion 8 and the extended return band 11 hangs down to the inner surface of the bag body 1, the bag folding portion 8 is refracted by the suspension of the holding area 5. It can be closed with both banks of the opening 6 along. The vertical width of the return band 11 is appropriate, and the lower side of the return band 11 may be a cut edge or a bag fold.
