Glass parison forming apparatus without gob handling devices
The granted patent (Publication Number: US11964901B2) discloses a glass parison forming apparatus that includes a feeder spout with an orifice ring, a plunger with a blow conduit, and a neck ring positioned downstream of the orifice ring. The apparatus is designed to support a freely suspended parison without the need for additional gob handling devices. The plunger is configured to push molten glass through the orifice ring and blow it into a parison, while the neck ring creates a neck finish that allows the parison to hang freely.
Furthermore, the apparatus features a heated orifice ring to control the temperature of the molten glass, a screw plunger with a centrally located blow conduit, and an annular space for feeding molten glass and blowing gas to form the glass parison. The system does not include a blank mold and is equipped with a compressed air source for operation. Additionally, the patent covers a glass container manufacturing system that incorporates the glass parison forming apparatus, a blow mold, and transfer equipment to move the parison from the neck ring to the blow mold for further processing.
