METHOD FOR THE PRODUCTION OF A REINFORCED THERMOPLASTIC CONTAINER

An internally reinforced thermoplastic container has a body manufactured using rotational molding. Prior to molding, attachment elements are releasably attached to the interior surface of parts of a mold, and an initially separate tension member is connected between the attachment elements. The mold is closed and a body of the container molded such that the attachment elements are integrated into the walls of the body. After molding, the attachment elements are released from the mold. The attachment elements and the tension member define a tension structure to resist outward bulging of the container walls. The tension member may be tensioned prior to or after molding of the container body. The attachment elements may take the form of eyelets having a base incorporated into the wall of the container body. The method enables the formation of a hollow thermoplastic container with integrally formed internal reinforcement.
