Abstract

PURPOSE:To manufacture a plural number of, perfectly closed hollow bodies by blow molding, by closing in the tube-like expanded parison within the molds having the protruding members being enabled to appear and disappear in the mold cavity and then protruding the protruding members. CONSTITUTION:The parison 3 closed at the lower end is expanded in tube-like shape by blowing compressed air. The parison 3 is closed in by clamping the molds 4, 4 having the protruding members 8, 8 which can apear and disappear in the mold cavity 6, 6, and then the protruding members 8, 8 are protruded and contacted at the both tips of the protruding members 8, 8. By so doing, the plural, perfectly closed hollow bodies can be manufactured by using blow molding alone.
