Abstract: A flexible hose of the invention has a hose wall which is formed by laminating resin layers. The resin layer acting as a gas barrier is formed by spirally winding a gas barrier resin strip and thermally fusing or bonding axially adjoining edges of the strip to each other. The resin layers are thermally fused or bonded to one another to become one piece.

Abstract: A pipe-end-connecting joint comprisse a nipple 1 inserted in the pipe end, a holder 2 for tightening the outer circumference of the pipe end, and an elastic packing 3 divided into half parts and attached in the holder 2. The nipple 1 includes a tubular portion 11 provided in one longitudinal end side thereof so as to be inserted in the pipe end, a connection portion 12 provided in the other longitudinal end side thereof so as to be connected to another joint, and a flange portion 13 provided in a longitudinal intermediate portion thereof so as to protrude outward.

Abstract: An excellent laminate applicable to various uses capable of overcoming drawbacks of a foamed polyethylene resin such as weak wear resistance and weak strength, by effectively covering the surface of the foamed polyethylene resin, in which a resin layer containing a graft copolymer of an ethylene-vinyl acetate copolymer resin and a vinyl chloride resin is laminated to a foamed polyethylene resin, and a resin layer containing a graft copolymer of an ethylene-vinyl acetate copolymer resin and a vinyl chloride resin is interposed between the foamed polyethylene resin layer and the vinyl chloride resin layer.
