Patent ID: 6901640

Claim:
An interment container, comprising: an outer container comprising a lower container member and an upper container member that cooperate to define an interior; and an inner liner located within the interior of the outer container, wherein the inner liner comprises a lower liner section defining a lower peripheral flange and an upper liner section defining an upper peripheral flange, wherein the lower and upper flanges of the lower and upper liner sections, respectively, are sealed together and wherein the lower and upper liner sections cooperate to define a sealed internal cavity located within the interior of the outer container to prevent leakage or infiltration of fluids into and out of the internal cavity; wherein the lower and upper flanges are formed of a thermoplastic material and are sealed together by means of a peripheral heating member located between the lower and upper flanges, wherein the heating member is adapted to be heated so as to impart heat to the thermoplastic material of the lower and upper flanges so as to liquefy the areas of the lower and upper flanges adjacent the heating member and to cause the material of the lower and upper flanges to flow together, wherein the liquefied material of the lower and upper flanges subsequently cools so as to solidify about the heating member and to form the seal between the lower and upper flanges; wherein the lower container member includes an upper edge, and wherein the lower liner section includes a flange adapted to rest on the upper edge of the lower container member to support the lower liner section, and wherein the lower container member includes a bottom wall and wherein the lower liner section includes a bottom wall spaced above the bottom wall of the lower container member when the flange of the lower liner section rests on the upper edge of the lower container member.
