Dispenser pouch and method for forming the same |
(57) A pair of superimposed panels are heat sealed together to define a reservoir in a
dispenser pouch, adapted to contain a liquid therein. A tapered-down neck is defined
on a lower end of the pouch and communicates with the reservoir to retain a pre-measured
charge of the liquid therein. Narrow overlying and unsealed panel portions at the
termination of the neck form a normally closed valve that opens when a predetermined
external pressure is applied to the pouch.
