A containment system comprising: a container ; a lid ; and a release mechanism comprising: a first member ; a second member ; and a separable element mechanically coupled to the first member and the second member; wherein, the separable element separates when heated to a predetermined temperature, releasing the first member from the second member , and separating the first member from the second member ; wherein the release mechanism separably couples the lid and the container together to close the container ; wherein the first member remains coupled to the lid when the release mechanism is separated; wherein the second member remains coupled to the container when the release mechanism is separated; characterized in that the second member includes a tendon that is rotatably coupled to the container ; and the release mechanism further includes a tendon retainer , with the tendon held between the first member and the tendon retainer , prior to separation of the release mechanism ; and it further comprises a latch that is rotatably coupled to the first member ; and in that opposite ends of the separable element are fixedly attached to the tendon retainer and the latch , respectively. a container ; a lid ; and a release mechanism comprising: a first member ; a second member ; and a separable element mechanically coupled to the first member and the second member; wherein, the separable element separates when heated to a predetermined temperature, releasing the first member from the second member , and separating the first member from the second member ; wherein the release mechanism separably couples the lid and the container together to close the container ; wherein the first member remains coupled to the lid when the release mechanism is separated; wherein the second member remains coupled to the container when the release mechanism is separated; characterized in that the second member includes a tendon that is rotatably coupled to the container ; and the release mechanism further includes a tendon retainer , with the tendon held between the first member and the tendon retainer , prior to separation of the release mechanism ; and it further comprises a latch that is rotatably coupled to the first member ; and in that opposite ends of the separable element are fixedly attached to the tendon retainer and the latch , respectively. a first member ; a second member ; and a separable element mechanically coupled to the first member and the second member; wherein, the separable element separates when heated to a predetermined temperature, releasing the first member from the second member , and separating the first member from the second member ; wherein the release mechanism separably couples the lid and the container together to close the container ; wherein the first member remains coupled to the lid when the release mechanism is separated; wherein the second member remains coupled to the container when the release mechanism is separated; characterized in that the second member includes a tendon that is rotatably coupled to the container ; and the release mechanism further includes a tendon retainer , with the tendon held between the first member and the tendon retainer , prior to separation of the release mechanism ; and it further comprises a latch that is rotatably coupled to the first member ; and in that opposite ends of the separable element are fixedly attached to the tendon retainer and the latch , respectively. <EOS>
