Abstract
A pouch for storing and dispensing liquid product in incremental amounts having a body portion and a pump tube portion, wherein the pouch can be held within a dispensing apparatus for squeezing the pump tube portion to release the incremental amounts. The improved pouch provides a pump tube portion made of thermoplastic polypropylene and butyl terpolymer rubber which can be readily sealed to the body without fitments or couplers. The improved pouch provides a built-in 'duck bill' check valve assembly or alternatively an O-ring check valve assembly, which further reduces the number of parts required as compared to the prior art. The check valve assembly provides a socket connector for mounting a separate nozzle assembly to the check valve assembly. A break-off tab for initially opening the nozzle assembly for dispensing is provided.
