In recent years, stick packaging bodies (packaging bodies) have been developed that wrap powdery foods, pharmaceuticals, and the like in a rod shape. The stick package is made of a laminate film in which a polyethylene terephthalate film, an aluminum foil, a polyethylene film or the like is laminated.
This stick package is formed by laminating both longitudinal edges (longitudinal seals) in the longitudinal direction of the laminate film in a palm shape and heat-sealing, while both lateral edges in the lateral direction of the laminate film thus formed in a cylindrical shape. The part (a pair of horizontal seal parts) is heat-sealed and has a rod shape. Therefore, portability and convenience are high, and opening is easy. However, since the stick packaging body is a bag having a special shape, the stick packaging body is manufactured using a dedicated stick packaging machine.

As shown in FIG. 11, the stick wrapping machine M supplies the contents to a wrapping paper supply unit 121 that supplies a laminated wrapping paper F wound around a reel, and a preliminary wrapping body P3 whose upper part is unsealed. A hopper 122 to be dropped, a guide cylinder part 123a for forming the wrapping paper F in a cylindrical shape, a vertical seal part 123 for attaching a vertical edge part of the cylindrical wrapping paper F, and a horizontal edge part in the longitudinal direction are attached. A horizontal seal forming part 124, cutters 125 and 126 that form notches at one end of one horizontal edge part, and a horizontal cutting cutter 128 that cuts the horizontal edge part to form a stick package 111.

  When manufacturing the stick package 111, first, the wrapping paper F is derived from the reel in the wrapping paper supply unit. Next, the wrapping paper F is formed into a cylindrical shape by the guide tube portion 123a, and the vertical edge portion of the tubular wrapping paper F is pasted by the vertical seal forming portion 123 to form a vertical seal portion. Then, the horizontal wrapping paper F is sequentially pasted at a predetermined pitch by the horizontal seal forming portion 124 to form the horizontal seal portion, while the contents in the hopper 122 (on the pre-packaging body P3 whose upper portion is not sealed) For example, sugar) S is dropped and filled. Next, the upper end portion of the preliminary package P3 is sealed with a horizontal seal portion, and a notch (cut) is formed in one horizontal seal portion with a cutter. Subsequently, the horizontal seal portion is sequentially cut by the horizontal cutting cutter 128. As a result, the stick package 111 is continuously manufactured (see Patent Document 1).
