<p>PROBLEM TO BE SOLVED: To manufacture a package capable of improving the appearance of an end face thereof, depressing the deterioration of a packaging material due to the folding thereof, and simply mounting a mouthpiece to the end face. SOLUTION: In this manufacture of a package, both end faces 14, 15 of a semipackage 12 which is in course of forming and in which seal parts 16, 17 are provided on both the end faces 14, 15 of a body 13 as one piece, respectively, are pressed, and both sides of each of the seal parts 16, 17, which are positioned in their longitudinal directions, are projected from both the end faces 14, 15 to form a pair of flaps 19, 20, respectively. By folding the flaps 19, 20 of at least one end face 14 among the flaps 19, 20 of both the end faces 14, 15 toward the side of the body 13 and joining them to the body 13, a package 11 is formed. The number of the folding of a packaging material is small and, accordingly, the packaging material is not deteriorated. Thus, the appearance of the end face 14 is improved and, further, a mouthpiece member can simply be mounted to the end face 14.</p> |
