Valve having a protective cage to prevent the valve opening being blocked by part of the bag on discharge

摘要

A valve (10) for use with a liner bag for a container is disclosed. A liner bag including the valve is also disclosed. The valve (10) includes a valve member (20) located in a valve seat and having a valve opening for egress of liquids from the liner bag. An operating lever (18) is positioned outside the liner bag. A protective cage (24) extends in front of the valve opening having a plurality of legs (26) supporting an open grid (28). The cage (24) is positioned inside the liner bag to prevent the wall of the liner bag from collapsing into the valve opening during emptying of liquids from the liner bag. A flange (16) extends around the valve seat to retain the valve in the wall of the liner bag. This arrangement prevents the liner bag wall from clogging the valve (10) during discharge of the bag's contents.
