Abstract

PURPOSE: To manufacture a plastic container having a narrowed opening which prevents the spill of liquid over the rib, by vacuum-forming a plastic sheet through a frame placed on the opening of a female mold.
CONSTITUTION: A plastic sheet 8 is supported by a supporting frame 7, and placed on the cavity 2 of a female mold 1 interposing a reinforcing frame 5. The sheet is softened by the heat of a heater, and expanded upwardly by air sent from an air tank 12 through a valve 14 to the cavity 2. The flow of the air is stopped, and a plug 10 is lowered to the expanded plastic bubble until the plastic is lowered nearly to the bottom of the cavity, when the sheet is vacuum formed by evacuating the space between the sheet and the cavity. The formed plastic container 15 has an upper opening 15A narrowed with the embedded reinforcing frame 5.
