ABSTRACT:
A foam play article comprises: an elastic tube for forming an elastic rubber layer; a foam formed by foaming polyurethane materials (2) in the elastic tube (1); and a coating layer (7) coated on the elastic rubber layer. The article may be manufactured by a method which comprises: providing polyurethane foam materials; attaching a material injector (5) to an elastic tube (1); injecting a predetermined amount of the polyurethane foam materials to the elastic tube (1) through the material injector (5); placing the elastic tube (5) in a mold (6) to provide a foam therein; applying a coating layer onto an outer surface of the foam; and drying the coated foam. The-thus formed play article has superior surface gloss, improved waterproof, soft tactile sensation, and higher stability.
