Abstract

PURPOSE:To smooth a surface remained after a blow-pin is taken out and keep air- tightness between a hard pipe to be inserted and the surface by applying a mold release treatment with fluorine resin to the blow-pin utilized to form an inner peripheral surface of a hose-connecting port blow-formed integrally with a vessel. CONSTITUTION:A mold release treatment with baked fluorine resin is applied to a blow-pin 2 and soft elastic vessel 3 of synthetic resin, having a hose-connecting port 4 integral therewith, is blow-formed from a material C. Blow-pressure is reduced comparatively in order to prevent from producing a clearance between the blow-pin 2 and the hose-connecting port 4 by reversed flow of air. After the formed vessel 3 is cooled, a metallic die 1 is opened and the pin 2 is pulled out of the connecting port 4. In this case, scratch will never be produced on the inner surface of the connecting port 4. A hard pipe 5 is inserted into the connecting port 4 and expands the inner diameter of the port 4, thus, the pipe 5 is prevented from slipping out due to a sufficient tightening force of the port 4. A suction or discharge hose f is connected to the pipe 5.
