METHOD OF PACKING LIQUID FILLING INTO SPOUTED POUCH AND SEALING THE POUCH AND APPARATUS THEREFOR

摘要

[PROBLEMS] To obtain a spouted-pouch package having a high degree of deoxidation by a method in which even a liquid filling which readily lathers can be packed while being inhibited from lathering. [MEANS FOR SOLVING PROBLEMS] A before-packing deoxidation step (1) is performed before a liquid filling is packed into a pouch. The step (1) comprises: a vacuum step (1-1) in which the pouch is evacuated under vacuum; an inert-gas blow step (1-2) in which an inert gas is blown into the pouch after the vacuum step; and a gas-diminishing vacuum step (1-3) in which the gas in the pouch after the inert-gas blow step is discharged under vacuum to diminish the gas in the pouch to a given amount. Thereafter, the pouch is evacuated in a second before-packing evacuation step (2-1) and then packed with the filling. After the packing, gas replacement is conducted. ® KIPO & WIPO 2009
