A container, comprising:
- a first container portion;
- a second container portion joined to the first container portion to define a sealed cavity therebetween;
- a coolant disposed within the cavity;
- and
- pressure relief apparatus operable to limit pressure in the sealed cavity.
A container, comprising:
- a first container portion;
- a second container portion joined to the first container portion to define a sealed cavity therebetween;
- a coolant disposed within the cavity;
- and
- a joined section that joins the first and second container portions wherein the joined section is operable to limit pressure within the cavity.
A container, comprising:
- a first container portion having a first wall, a base portion and a first rim;
- a second container portion having a second wall and a second rim wherein the second rim is joined to the first rim, thereby defining a cavity between the container portions;
- a cross-linked gel disposed within the cavity;
- a first raised portion integral with the second wall wherein the first raised portion joins the second wall to the base portion and is rupturable in response to a first elevated pressure;
- and
- a second raised portion integral with the second wall wherein the second raised portion joins the second wall to the base portion and is rupturable at a second elevated pressure greater than the first elevated pressure.
