Document Type and Number:
Japanese Patent JP4509515
Kind Code:
B2
Abstract:
A hollow plastic product including a hollow main body (1), a reinforce member (2) and a connector pipe (5) is provided. The hollow main body (1) is a duct, hose or tube extending over a length, and the reinforce member (2) is ring-shaped so that it extends around a circumference of an outer surface of the hollow main body (1). The reinforce member (2) is manufactured by injection molding and is used as an insert when blow-molding the hollow main body (1), so that the reinforce member (2) is integrally formed with the main body (1). The reinforce member (2) has a defined welding surface (3) formed with a first hole, to which one end surface (5a) of a connector pipe (5) is thermally welded. Then the hollow main body (1) is formed with a second hole in alignment with the first hole, thereby defining a fluidic communication between the hollow main body (1) and the connector pipe (5).
