ABSTRACT:
A method of making a container (10) having a unitary spout pull tab from a continuous sheet of flexible material (11) comprises the steps of folding the sheet to form two opposite side walls (23) joined at a bottom end by a bottom wall (20) and open at a top end opposite the bottom wall. Elongated portions of the two side walls are sealed together along their side edges to form two side seals (27) at least one of which includes a tab portion (12). Two breachably sealed V-folds (33, 34) are formed in the side walls adjacent the top end straddling the tab portion of the one side seal. Upon manually pulling the tab portion of the one side seal, the breachable seals of the V-folds straddling the tab portion of the one side seal may be broken and the two V-folds pulled outwardly to collectively form an open spout (S).
