は困難性が生じてしまうものであった。The hollow body is required to have various shapes depending on the intended use while ensuring its strength, and has a straight line portion, a bent portion and the like. In a series of hollow bodies, flexibility is required in the bent portion, and therefore if the material of the hollow body is made to have flexibility, the strength of the hollow body will be insufficient. Therefore, in order to make up for the lack of strength, a method is employed in which a hard (for example, metal) reinforcing member is provided in a portion other than the bent portion, and the bent portion has, for example, a bellows shape to maintain flexibility. However,
In this method, the structure is complicated, which causes an increase in manufacturing cost. Particularly, the bellows-shaped molding is difficult.

金型の他、樹脂型であっても良いのは無論である。The hollow resin body of this embodiment can be manufactured by blow molding. Molding is performed by using molds 18 and 20 having a cavity 28 suitable for product use as shown in FIG.
First, the net 12 is installed therein. The net 12 is installed in the molds 18 and 20 so as to be formed at a desired position of the hollow body 10. Further, guide rings 14 and 16 as shown in FIG. 4 are fitted to both ends of the net 12. Since the net 12 has elasticity, it is difficult to maintain its cylindrical shape, but by inserting the guide rings 14 and 16 into the net 12, the cylindrical shape of the net 12 can be maintained and the parison can be easily inserted. You can Further, the net 12 is preferably of a size that can be attached to the hollow body in a slightly expanded state. Type 1
8 and 20 are closed, and then the parisons 24 and 24 are extruded from the die head 22 into the cavity 28, and the parison 24 and 24 are further inserted into the net 12. And
When the parisons 24, 24 are pushed out by a predetermined amount, gas is injected from the blowing device 26 to form the parison 24, 24 in the mold 1.
The resin hollow body having a predetermined shape is obtained by swelling along the inner walls of 8 and 20. Further, the net 12 is formed together with the molding of the hollow body 10.
Adheres to and is integrated with the hollow body 10. At this time, the guide rings 14 and 16 are interposed between the hollow body 10 and the net 12, but the material of the hollow body 10 and the guide rings 14 and 16 are different from each other.
If the materials of are the same or equivalent, the hollow body 10
The guide rings 14 and 16 can be fused together, which is more preferable. In addition, the resin of the parison 24 may take in the net 12 due to the roughness of the net 12 and be embedded in the hollow body 10 in which the net 12 is molded.
Even if the net 12 is embedded in the hollow body 10, it does not matter because it is reinforced as a hollow body while being reinforced. rather,
It is preferable because the net 12 and the hollow body 10 can be more integrated and the appearance can be improved. Needless to say, the molds 18 and 20 may be resin molds instead of metal molds.

ることができる。In the manufacturing method of this embodiment, the hollow body 10 can be molded and the net 12 can be integrated at the same time, so that the number of manufacturing steps does not increase significantly. Particularly, by using the guide rings 14 and 16, the parison 24 and 24 can be easily inserted. Therefore, the guide ring may be installed so that the parison 24, 24 can be easily inserted, only one end (guide ring 14) may be installed, and not only the end part but also the middle part of the net 12 as necessary. You may install more than one. In the hollow resin body of this embodiment, the net 12 is covered as a reinforcing material at least where the strength is required. Therefore, sufficient strength can be secured as a hollow body product. Moreover, since the net 12 is flexible, the net 12 can be attached to the bent portion of the hollow body. Further, since the net 12 is stretchable and covers the hollow body 10 in a slightly expanded state, the hollow body 10 and the net 12 are brought into close contact with each other. Therefore, since the hollow body of the present embodiment can have both flexibility and strength, it is not necessary to make the bent portion have a bellows shape, and the structure can be simplified. In particular, since the net 12 is easily attached, the manufacturing cost can be reduced.
