Abstract

PURPOSE:To form the trap collecting drain from plural positions without thinly making up it by a method wherein a by-pass for connection is previously inserted and housed in a space section housing the by-pass for connection bored and mounted to a cavity section of the drain trap body, and blowing-formed. CONSTITUTION:A pair of dies 2 of a molding machine 1 are opened, the by-passes 6 for connection in plastic, inner end outer fringes thereof have flanges 5, are inserted into space sections 4 housing each by-pass for connection, and housed and arranged projecting each flange section into the cavities (b), a parison extrusion-molded is supplied and the dies are clamped. Air is blown in from an air blowing port 9, the trap with a predetermined shape is formed while the expanded parison is intruded into the flanges of the by-passes for connection and bonded integrally, and the trap collecting drain from plural positions, which has the solid by-passes for connection with necessary thickness at the both outsides of the trap body in integrally projecting manner, is easily manufactured positively.
