ABSTRACT:
A method for scaling a flexible inner bag inside a squeezebottle so that the flexible inner bag will invert in order to dispense viscous fluids. The method is particularly useful in single-piece squeezebottles which have a small ratio of discharge opening cross-section to body cross-section. In practicing the present invention, a flexible inner bag has heat-activated adhesive stripes applied to the upper half of its exterior. The flexible inner bag is inserted into a squeezebottle through the discharge opening and then expanded inside the squeezebottle by compressed air. After the flexible inner bag is fully expanded, and with pressure applied to the inside of the flexible inner bag, heat is applied either to the inside of the bag or to the outside of the squeezebottle by hot air, steam, radiation, or induction heating of metal particles in the adhesive. The adhesive is heat-activated and the upper half of the flexible inner bag is thereby attached to the inner side wall of the squeezebottle.
