Document Type and Number:
Japanese Patent JP2840969
Kind Code:
B2
Abstract:
A container filling nozzle 1 of rubber has a wide, substantially square, inlet opening and a cruciform outlet slit 4 which, in the absence of external force, is maintained closed owing to the resilience of the rubber. In the zone of the slit 4, the internal surface of the nozzle wall is formed with protrusions 5 which extend along both sides of each of the arms of the slit 4 and constitute respective thickenings. The protrusions 5 terminate short of the central ridge 6 of the V-form lips 7 of the nozzle 1. Thus, the lips 7 have their outlet zones more rigid and yet retain the necessary flexibility, so that sealing of the slit 4 is improved and yet the lips 7 can open wide.
