The double-walled bag shown in Japanese Patent Publication is cited. As shown in FIGS. 7 and 8, the multi-walled bag (multi-layered pouch) shown here includes an outer cylinder 52 that cannot be heat-sealed and an inner cylinder 51 that is heat-sealable and is housed inside. In this multi-layered bag, the inner cylinder 51 and the innermost layer 53 of the outer cylinder 52 are bonded in the circumferential direction at both ends 57 and 58, and the inner walls of the inner cylinder 51 are heat-sealed to each other slightly above the lower end 58. By doing so, a wide intermediate body 54 is formed. The heat seal portion 54 is horizontally moved by the pressing rolls 55 and 56.
It is cut into 4a and 54b to form a multi-layered pouch containing a bottomed inner cylinder. As shown in FIG. 9, in this multi-layered bag, the upper portion of the inner cylinder is heat-sealed after the contents 59 are filled from the upper opening, and the heat-sealing portion 5
Only the inner cylinder is taken out in the state of being cut in the lateral direction at 0.

袋が完成する。Next, with reference to FIGS. 2 to 4, the manufacturing process of the above-mentioned multi-layered bag will be described. First, as shown in FIG. 2, an inner layer bag 5 also made of a tubular body is arranged inside an outer layer bag 1 made of a tubular body, and a top adhesive paste 11 is placed at the lower end of the outer layer bag 1.
In addition, a sealing portion 10 is formed by heat sealing at the lower end of the inner bag 5 leaving a margin at the tip. Further, the sealing part 10 has a perforated slit 12 over its entire line.
To form After the tip of the inner layer bag 5 is fixed to the inner wall of the outer layer bag 1 with the adhesive 11 and positioned, the lower ends of the outer layer bag 1 and the inner layer bag 5 are folded as shown in FIG. 1 is sealed with the bottom adhesive paste 2 shown in FIG. 1 to complete the multilayer adhesive bag shown in FIG.

ら、それぞれ開かれた状態になる。As described above, in the multi-layered bag of this embodiment, the outer bag 1 and the inner bag 5 are separated while adopting the conventional manufacturing process of fixing and positioning on the inner wall of the outer bag 1 with the adhesive paste 11. It is possible to form the slit 12 that can be formed. FIG. 5 is an explanatory view showing the filling state of the contents in the above-mentioned multi-layered bag. As shown in FIG. 5, when the contents are filled into the inner bag 5 from the upper opening, the bag body is caused by the weight of the contents. The "α" on the bottom is more self-adhesive and adheres to the outer bag. This is because the inner layer bag is formed larger than the outer layer bag by "α", whereby the bottom sticking portion 3 and the folding portion 7 shown in Fig. 1 are changed from the folded state to the opened state. Become.

る。Therefore, as in the conventional case, the upper end opening is narrowed in the side walls of the inner layer bag 5 and the outer layer bag 1, and the inner layer bag 5 is formed.
The force that separates the outer bag 1 from the outer bag does not act, so that the outer bag 1 and the inner bag 5 are slid when the contents are filled and the outer bag 1 and the inner bag 5 are maintained while maintaining the conventional manufacturing process. Can be effectively prevented.

(A) Since the inner bag is configured to be larger than the outer bag by “α” when the contents are filled, the upper end of the inner bag does not become tight, so that the inner bag and the outer bag have side walls, The force that narrows the opening at the upper end and separates the inner bag from the outer bag does not work, and while maintaining the conventional manufacturing process, it is effective to drag the outer bag and the inner bag and peel the outer bag from the inner bag. Can be prevented. (B) The outer bag is made of a material such as paper that cannot be heat-sealed,
And by using a known means by forming the inner bag from a heat-sealable material such as plastic,
After sealing the outer layer bag, the inner layer bag and the outer layer bag can be separated. (C) By fixing the paper outer layer bag and the plastic inner layer bag with an adhesive, the operability can be improved especially in the cold season. (D) After filling the inner layer bag with the contents and sealing the inner layer bag and the outer layer bag, forming an upper separation zone capable of separating the inner layer bag and the outer layer bag at the upper end sealing portion of the inner layer bag, or by dot attachment By peeling off 6, the inner layer bag can be separated into the outer layer bag and the inner layer bag by the separation band formed at the lower end joint and this upper separation band, and only the inner layer bag can be taken out after opening the outer layer bag. It will be possible.
