ある。FIG. 5 shows an example of the manufacturing method. That is, the composite sheet material 20 is placed so that its base resin sheet layer 21 is on the female mold 32 side of the vacuum forming machine 30 and vacuum formed. The female die 32 is provided with a concave die 33 for forming an article storage section for accommodating an article to be packaged, and a convex die 34 for forming a ridge line. Then, while performing vacuum forming, the female mold 32 and the cylindrical male mold 31 that maintains a predetermined thickness are pressed from the foamed resin sheet material 22 side of the composite sheet material 20, thereby forming the base resin sheet layer 21 and the foamed resin sheet layer. A contact point P with 22 is bonded to form a gap S. Then, a predetermined shape is also given to the foamed resin sheet layer, whereby the entire composite sheet material 20 is molded into a desired article packaging container shape. Reference numeral 35 is a vacuum suction hole.

もでき、この考案のもたらす効果は大きい。(Operations/Effects) As illustrated and explained above, according to the article packaging container of this invention, the top of the side wall of each article storage section forms an acute ridgeline, compared to conventional article packaging containers. However, since the opening of the article storage section has a high degree of deformation and flexibly deforms depending on the size of the object to be packaged, and conforms to the shape of the object to be packaged, the object to be packaged can be wrapped securely and there is no possibility of rubbing around the ball or against the container. and pressure could be prevented. In addition, since a composite sheet material composed of a base resin sheet layer and a foamed resin sheet layer laminated on the side of the packaged object of the base resin sheet layer is used, contact between the case and the packaged object can be softened. This idea has a great effect.
