SODA POP BOTTLE HAVING EXPLOSION-PROOF STRUCTURE AND DEVICE THEROF

摘要

PURPOSE: A soda pop bottle makes of polyester which has an explosion-proof structure to decrease explosion on the bottom under outer shock. CONSTITUTION: A soda pop bottle contains an explosion-proof by forming one body which has a outer gate projecting part and an inner dome reinforcement part of the center in the bottom of a drinking bottle being beginning explosion under outer shock. Also, the gate projecting part and the dome reinforcement part is provided which is equipped for forming gate way in the preform being mold of modeling step of a half-processing bottle is equipped space for the protecting of a gate projecting part. And a stretching road being a shifter for pressure molding contains the form for a dome reinforcement part, so the process uses not polyester having high viscosity, improves an explosion-proof, protects inner content.
