<p>This method for the manufacture of hollow bodies which do not contaminate the products contained therein, consists of maintaining the heat of molding of a hollow body, forming a container (1) having an embouchure (2) and produced by molding a first thermoplastic synthetic resin, in which there is applied in the interior thereof, a set amount of a second thermoplastic synthetic resin (9) having a melting point lower than the temperature of the hollow body due to the residual molding heat thereof, after which the second resin (9) is rotary molded within the hollow body, which acts as a mold, until the second resin (9), after being melted by the residual heat, has solidified forming a lining (10) applied over the entire inner surface of the hollow body and the entire inner periphery of the rim of the embouchure (2). <IMAGE></p> |
