Zusammenfassung: | PROBLEM TO BE SOLVED: To stably fix a neck suspension bag around the narrow neck of a bottle without bag portion's being shaken on the peripheral edge of the bottle. SOLUTION: Two thermoplastic resin films, one for the surface and the other for the back, are superposed, and both side edges of the superposed films are thermally welded to define the side edges. A sectioning heat seal line is formed in the middle of the superposed films, thereby sectioning it into the bag portion and a neck suspension portion. The middle of the neck suspension portion having a three-layer structure is fused in the shape of a through-hole greater than the diameter of the capped narrow neck of the bottle. Thereby the through-hole is formed in a substantially inverted mount shape that has as its bottom edge the sectioning heat seal line of the neck suspension portion. At the same time, a back fixed flap in the substantially inverted mount shape is formed by the heat fusion of the through-hole. Thus, the neck suspension bag for the bottle with the narrow neck is formed. COPYRIGHT: (C)2010,JPO&INPIT |
