【発明の詳細な説明】
この発明は物品を収容した際角底になるようにした紙袋
に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper bag that has a square bottom when containing articles.
この種の紙袋は左右両側面をＭ状に折曲し、底部を扁平
状に形成したものであるから使用時にＭ形側面を開くと
き底部は円滑は開かれず、底面の形成が仲々むづかしい
欠点があつた。This type of paper bag has both left and right sides bent in an M shape, and the bottom is flat, so when the M-shaped sides are opened during use, the bottom does not open smoothly, making it difficult to form the bottom. It was hot.
この発明の目的は前記従来の欠点を解消し、Ｍ形折曲側
面を開くことにより直ちに底面が綺麗に形成できる紙袋
を提供することにある。An object of the present invention is to eliminate the above-mentioned drawbacks of the conventional paper bag and to provide a paper bag whose bottom surface can be formed neatly immediately by opening the M-shaped bent sides.

によつて生じた三角形部５、５をＭ形折曲側面２の内側
に折込んだことを特徴とする紙袋である。However, in this invention, M-shaped bent side surfaces 2 are provided on both left and right sides of the bag body 1, and the M-shaped bent side surfaces are provided on the front back plates 1a and 1b at the lower end corner portion 3 of the M-shaped bent side surfaces 2. Slanted folds 4, 4 reaching a depth of 2 are made, and the folds 4, 4
This paper bag is characterized in that the triangular parts 5, 5 produced by this process are folded inside the M-shaped folded side surface 2.

の袋にも直ちに実施できる等の効果がある。In the embodiment shown in FIG. 4, the triangular parts 5, 5 are adhered to the M-shaped bent side surface 2 with an adhesive 6. The bag body 1 is made by folding a long and thin sheet of paper in half to form the front and back plate 1a.
, lb are formed, and both left and right ends of the front and back plates 1a and Ib are bent inward to form bent pieces 2a and 2b, respectively, and a joining piece 2c is connected to one of the bent pieces 2b. The M-shaped bent side surface 2 is formed by adhering it to the other bent piece 2a.
Note that the symbol T in the figure indicates the bottom surface. Since this invention has the above-mentioned configuration, the mouth of the bag main body 1 is opened and the M-shaped bent side surface 2 is opened.
When stretched, the triangular parts 5, 5 naturally expand to form a part of the bottom surface 7 as shown in FIG.
can be opened smoothly and easily to form a square bottom, and since there are no seams on the bottom, there is no need to worry about the bottom falling out. In particular, in this invention, the structure is extremely simple because a triangular portion is provided at the lower end of the M-shaped bent side surface and the triangular portion is simply bent to the M-shaped bent side surface. Because of its structure, it is extremely durable and can be applied immediately to existing bags.
