Description

TECHNICAL FIELD The present invention relates to a bag material for making a handbag having a double opening upper edge portion.

2. Description of the Related Art Since the upper edge of the opening of a conventional handbag paper bag is the part that is most likely to be damaged by taking things in and out of the bag, as shown in FIG. 9, it is attached to a paper bag 1 through a reinforcing paper 2. A folded portion 5 having a notch portion 4 corresponding to the handle string 3 is formed, and the upper edge of the opening of the paper bag 1 is bent inward.
The folded-back portion 5 was attached to the inner surface of the sheet with an adhesive to reinforce the opening upper edge of the paper bag 1 as a double layer.

However, the cord attachment portion of the reinforcing paper 2 is folded back at the folded portion 5.
Since it is not hidden by the notch portion 4, the appearance is not good, and this portion is not reinforced by the folded-back portion 5, and the notched portion 4 of the folded-back portion 5 is formed by punching. Therefore, a paper having a shape corresponding to the notched portion 4 is formed. A lot of chips were generated, cleaning was difficult, and bag making was troublesome.

In addition, in order to improve the above-mentioned drawbacks of the prior art, a vertical cut is provided at the upper peripheral edge of the bag main body at the corresponding position of the bag, and the bag is folded back inward and downward of the peripheral edge, and the folded back section is reinforced with the paper bag main body and the reinforcement. Handbag paper bag adhered to the inner surface of paper
It has been proposed as No. 119357 (No. Shokai 55-36158).

However, since the cut is formed up to the fold line of the folded part, the upper edge of the cut where the bag is inserted becomes a single layer, the paper bag easily tears from this part, and the insertion part of the bag can be seen from the outer surface. It is difficult to put the handle in because the insertion part of the handle consists of only a cut, and the back end of the cut is expanded by the handle, so a crack is created at the back end and it looks bad and is formed by the handle. Since the edge of the cut is located on and adhered to the bulging portion to be formed, the folded portion is easily peeled off from the cut.

Further, each of the bent portions is provided with a pair of slots or notches having a length that does not reach the fold line from its edge toward the fold line. Proposed as Japanese Patent Application No. 57-75435 (No. Sho 58-177350) is a paper bag in which both ends of the lower hand string are passed through the slot or cut and the lower hand string is led out of the opening of the paper bag. Has been done.

However, this method is troublesome in processing because a cutout piece is generated during the formation of the slot, and in the case of forming a mere cutout, the above-mentioned Japanese Patent Application No. 53-119357 (Actual No.
Like No. 5-36158), it is difficult to pass the lower hand string, and the inner edge of the cut is spread by the lower hand string to cause a rift, and the edge of the cut is located on the bulge formed by the lower hand string. Since they are bonded together, the bent portion is easily peeled off from the bulge portion formed by the string.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The object of the present invention is to solve the above-mentioned disadvantages and to prevent the bag from being damaged from the cutout portion because the cutout portion is not doubled by continuously folding the lip of the bag. The string attachment part is completely hidden and looks good without being exposed.Reinforcing this part to improve strength, fold it back from the back end of the side cut line parallel to the vertical cut line and bend it. By forming the bent part, a wide string insertion groove can be formed without generating chips, it is easy to insert the string into the cut line, and the back end of the cut line is not expanded with the string and from the cut line Without making a tear, the vertical cut can be located outside the upper surface of the bulging string, the folded part does not easily peel off from the cut, paper chips do not occur, and bag making is easy The object is to provide a bag material that can be carried out.

Means for Solving the Problems The present invention provides a bag material having an upper edge portion provided with a folded-back portion that is bent inward, and a plurality of vertical cut lines are provided in the folded-back portion up to a point where a fold line is not reached from the edge. At the same time, it has a configuration characterized in that a cut line to the side is provided at the back end thereof.

Action The string restraining part is folded back to the side from the deep end of the cut line to the side provided at the deep end of the cut line of the folding part formed on the upper edge of the bag material, and the string attached via the reinforcing paper is attached. After passing the paper restraining part through the notch formed by folding back, bend the upper edge of the opening of the bag inward and attach the folding part to the inner surface of the bag with an adhesive, and then the folded string restraining part Then, the reinforcing paper is hidden inside the folded-back portion, the insertion portion of the cord is hidden inside the bag, and the upper edge of the opening of the bag and the insertion portion of the cord are doubly reinforced.
