BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stick type packaging body for packaging contents such as granules, powders, solid bodies, liquids and the like of foods and medicines, and an apparatus for producing the same, more specifically,
The present invention relates to a long stick-type package having both edges sealed in the longitudinal direction and a manufacturing apparatus for the same.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 11, a long stick-shaped package 51 is composed of a plurality of laminated films in which polyethylene terephthalate film, aluminum foil, polyethylene film and the like are sequentially laminated. It is made of a laminated material, and has both longitudinal edges formed in the longitudinal direction in a bag shape having a dorsal fin portion 54 that is heat-sealed in a palm shape, and is formed at both ends in the longitudinal direction. The lateral seal portions 53, 53 are formed by heat-sealing the edges of the sealed horizontal seal portions 53, 53 and filling the bag portion 52 with the contents. Further, the lateral seal portions 53, 53 are formed such that the outer peripheral corner portions are in the shape of a pin corner, and the lateral seal portions 53.
The base portion 55, that is, the portion connected to the bag portion 52 was formed in a straight line so as to be orthogonal to the longitudinal direction.

As shown in FIG. 12, a known packaging machine 60 for producing the stick type package 51 has a supply section 62 for supplying a laminated wrapping paper F wound on a reel 61 and a spare. A hopper 63 that drops the contents S to fill the package 51A with the contents S, a guide tube portion 64 that forms the wrapping paper F into a tubular shape, and a vertical edge portion of the tubular wrapping paper F are attached. A vertical seal forming portion 65, a horizontal seal forming portion 66 for attaching a horizontal edge portion in the longitudinal direction, a cutter 67 for forming a notch, and a horizontal seal cutting for cutting the horizontal seal portion 53 to form a package 51. And a portion 68 (see Japanese Patent Laid-Open No. 11-263374).

In this packaging machine 60, in particular, the horizontal seal cutting section 68 has a movable blade 69a and a fixed blade 69b, and cuts the horizontal seal section 53 linearly so as to be orthogonal to the longitudinal direction. Therefore, the movable blade 6 formed in a flat plate shape
9a is configured to be cut by moving toward a fixed blade 69b formed in a flat plate shape. And
Almost no scrap is generated by this cutting.

However, in the conventional stick-type packaging body 51, the fact that the corner portions of the lateral seal portion 53 are formed in the pin-corner shape means that the stick-type packaging body 5 is formed.
If the corner of No. 1 is applied to the body, it is likely to be injured due to the pin angle, and at the time of manufacturing a large amount of stick-type packaging bodies 51, the other stick-type packaging bodies 51 are attached to the lateral seal portion 5.
It was easy to break with the pin angle of 3.

Therefore, the removal of the pin angle has been left as an issue. In order to remove the pin angle, the pin angle has to be removed when the stick package 51 is manufactured, and the cut pin angle remains as scrap, so the treatment method must be considered. Moreover, even if the structure of the horizontal seal cutting portion 68 is made more complicated than the current one in order to remove the pin angle,
It had to be constructed as cheaply as possible.

Further, since the base portion 55 of the horizontal seal portion 53 is formed in a straight line, a pin angle is formed at both ends of the connecting portion between the horizontal seal portion 53 and the bag portion 52. If the contents filled in the portion 52 are, for example, granules or powders, it becomes easy to store the contents in the corners when the contents are discharged to the outside, and a predetermined amount is taken. It was easy to dispose of without doing.

The present invention solves the above-mentioned problems, and provides a stick-type packaging body which can be used almost without any danger and in which the contents filled in the bag portion are used. An object of the present invention is to provide a stick-type package manufacturing apparatus that can configure a manufacturing apparatus at a low cost and collect scrap.
