Abstract
The present invention relates to an installation for manufacturing a receptacle from a preform of thermoplastic material, the receptacle being suitable for being subsequently subjected, without significant deformation, to relatively severe temperature conditions encountered during hot-filling or pasteurization processes. The installation includes means for manufacturing a receptacle blank having a hot-shrunk body from the preform, and molding means for forming a final receptacle from the blank. The means for manufacturing a receptacle blank are adapted to form a blank whose shrunk body is longer than the body of the final receptacle to be obtained. The molding means are described in detail.
