Abstract (en)
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.
