Method for the production of a reinforced thermoplastic container

A method of forming a reinforced thermoplastic container, the method comprising:

• providing a mold having at least two mold parts, each mold part having an inner side and an outer side;
• releasably securing at least one attachment element to the inner side of at least one of the mold parts;
• connecting a tension member to the at least one attachment element after releasably securing the at least one attachment element to the inner side of the at least one of the mold parts;
• tensioning the tension member and securing at least one end of the tension member outside of the mold cavity;
• adding a thermoplastic material onto the inner side of the at least one of the mold parts while the tension member is connected to the at least one attachment element;
• closing the at least two mold parts to define a mold cavity after connecting the tension member to the at least one attachment element;
• heating the thermoplastic material after closing the at least two mold parts;
• and
• distributing the heated thermoplastic material at the inner side of the at least two mold parts after closing the at least two mold parts to create a molded body of the reinforced container.

A method of forming a reinforced thermoplastic container, the method comprising:

• providing a mold having at least two mold parts, each mold part having an inner side and an outer side, wherein at least one of the mold parts comprises a port having an openable closure member;
• releasably securing at least one attachment element to the inner side of at least one of the mold parts;
• connecting a tension member to the at least one attachment element after releasably securing the at least one attachment element to the inner side of the at least one of the mold parts;
• adding a thermoplastic material onto the inner side of the at least one of the mold parts while the tension member is connected to the at least one attachment element;
• closing the at least two mold parts to define a mold cavity after connecting the tension member to the at least one attachment element;
• accessing the mold cavity through the port after closing the at least two mold parts;
• fixing the tension member within the mold cavity;
• heating the thermoplastic material after closing the at least two mold parts;
• and
• distributing the heated thermoplastic material at the inner side of the at least two mold parts after closing the at least two mold parts and fixing the tension member within the mold to create a molded body of the reinforced container.

A method of manufacturing a thermoplastic container having an internal tension structure, the method comprising:

• assembling a mold comprising at least two mold parts to define a mold cavity;
• releasably securing a plurality of attachment elements to inner surfaces of the mold parts at positions defining walls of a container body;
• connecting an elongate tension member to the plurality of the attachment elements after releasably securing the plurality of attachment elements to inner surfaces of the mold parts;
• and
• molding the container body from a thermoplastic material within the mold cavity and integrating the attachment elements into the walls of the container body.
