ABSTRACT:
Containers for materials which are to be microwave heated such as in digesting or extracting operations, are made of thermoplastic material, such as a fluoropolymer, e.g., TEFLON.RTM. PFA, that is strengthened by reinforcing means that may be a fiber reinforced thermoplastic of high tensile strength, such as polyetherimide, e.g., ULTEM.RTM., with reinforcing continuous fibers in a matrix of such thermoplastic, which fibers are preferably of glass or other heat resistant and microwave transmissive material. The containers may be strengthened by incorporating the fiber reinforced thermoplastic in a wall or walls of the container or by inserting the container into a reinforcement, which is a sleeve or collar of the reinforced thermoplastic. In both such constructions the reinforcing means protects the container against peripheral or radial failure due to pressure that is generated by the microwave heating of the container contents. Also described are processes for manufacturing the described reinforcing means and for utilizing containers protected by such means.
