| 摘要 |
The blow-molded hose of a synthetic resin of the present invention is produced by blow-molding a single parison comprising a soft resin and a hard resin. The blow-molded hose comprises a monolayer (or single-layer) segment formed with either a soft resin layer or a hard resin layer and multilayer (laminating) segment formed with the soft resin layer and the hard resin layer, wherein, in the multilayer (laminating) segment, the thickness of the resin layer forming the monolayer segment is thinner than that of the other resin layer. Practically, the monolayer segment comprises the soft resin layer and forms the connection end (s) at the end (s) of the hose.
