Abstract (en)
[origin: EP0229420A1] A process for hot filling a thermoplastic container so as to avoid deformation and collapse of the container, resulting in a container with a concave base which comprises the steps of continuously applying a vacuum means to the base of a thermoplastic container so as to draw down the base of the 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 base, in the absence of the external vacuum, inverts to a concave shape, which was its original formed shape.
