ABSTRACT:
A thermally activated self-releasing seal for a thermal mass container comprising (a) seal support located on the exterior of, separate and detached from, the container; (b) a fusible seal, attached to the seal support, to form a one piece seal when combined with the seal support; and (c) apparatus for attaching the fusible seal portion of the one piece seal to the container to cover the aperture, wherein the apparatus for attaching is located on the exterior of and is separate from the container. According to a preferred embodiment of the invention the apparatus for attaching is an adhesive, such as a room temperature vulcanizing rubber (an RTV), a two part epoxy, or the like; having the property that heat is not required in order to accomplish the attachment of the fusible seal portion of the one piece seal to the container. The invention is particularly useful in sealing smooth walled thermal mass containment vessels, joining fusible seals to containment vessels made of incompatible materials from a bonding point of view, etc. Furthermore, the invention is useful for sealing thermal mass containers incorporated into state of the art flight data recorders, which use the thermal mass to protect sensitive electronic components from fire damage.
