Abstract (en)
[origin: EP0224316A1] A method of hot filling a thermoplastic container so as to avoid deformation and collapse of the container, which comprises the steps of continuously applying a vacuum means to the original side walls of a thermoplastic container so as to draw out concave indentations in said original side walls of said container into a convex shape, filling the container with desired contents during continuous application of the vacuum means, sealing the container by an appropriate sealing means during continuous application of the vacuum means, discontinuing the vacuum means, and cooling the container, whose convex side walls, in the absence of the external vacuum, invert to indentations of a concave shape, which was its original formed shape.
