  • Double walled insulated container with rechargeable vacuum
    Patent number: 9254063
    Abstract: An insulated container is disclosed. The container has an outer plastic member, an inner plastic member and an insulating, e.g., vacuum space, located therebetween. A vent assembly is located in the outer member in communication with the vacuum space. The vent assembly may be arranged to prevent liquid from entering into the insulating space and may be arranged to equalize the internal pressure within the insulating space and the ambient atmospheric pressures surrounding the outer member, while allowing higher internal pressure within the insulating space to vent to the ambient atmosphere when the container is heated, and to close off to seal the insulating space to maintain the vacuum therein when the container is cooled.
