Abstract
A protective device for a container containing toxic or hazardous materia includes a shell, a mechanism positioned in the shell for sealing a puncture in the container so as to prevent release of the toxic materials from the container and a mechanism for attaching the shell to the container.
Claims18
A removable protective device for mounting on and surrounding a localized section of a container containing a solid mass heat source and an initiator for heating the heat source to a temperature above a melting point of the heat source whereby the heat source is brought to a molten state in the localized section of the container surrounded by said protective device, said protective device comprising:
- a shell, said shell having inner and outer walls defining a space therebetween;
- self-sealing means positioned in said space, said self-sealing means being pre-compressed between said inner and outer walls;
- and
- mechanical mounting means for securably and releasably attaching said shell to the container, whereby upon said protective device being mounted to the container said self-sealing means act to seal a puncture in the container so as to prevent release of the molten heat source from the container.
An improvement for a container containing therein a solid mass heat source and an initiator for heating said heat source to a temperature above a melting point of said heat source whereby said heat source is brought to a molten state, wherein the improvement comprises:
- a protective device adapted for mounting on said container, said protective device including a shell having inner and outer walls defining a space therebetween;
- a high-temperature foam positioned in said space, said high-temperature foam being pre-compressed between said inner and outer walls;
- and
- mechanical mounting means for securably and releasably attaching said shell to said container, whereby upon said protective device being mounted to said container said pre-compressed high-temperature foam acts to seal a puncture in said container so as to prevent release of said molten heat source from said container.
