Title:
METHOD AND DEVICE FOR GAS REPLACEMENT OF CONTAINER
Document Type and Number:
WIPO Patent Application WO/2011/151902
Kind Code:
A1
Abstract:
Disclosed is a device for gas replacement capable of reducing the amount of replacement gas, improving a gas replacement rate, and reducing the amount of spilt liquid. In a replacement nozzle (11) which jets out the replacement gas toward the container opening portion symmetrically about the center line along the radial direction of the container, the space between the outermost sidewalls of the nozzle opening is partitioned with a plurality of wind direction adjustment plates (16a, 16b) to generate a plurality of blow out openings. The replacement gas jet streams jetted out along the outermost sidewalls of the nozzle opening are so jetted inward as to form an angle of 100º to 130º. Moreover, the replacement gas is jetted out of the replacement nozzle to the range between the level lower than the end of the can opening by one third or more of the height of the can neck portion and the level equal to or higher than the height of the can cover.
