Title:
VACUUM SEALED LID INSERT FOR INSULATED CONTAINER
Document Type and Number:
WIPO Patent Application WO/2019/140177
Kind Code:
A1
Abstract:
An insulated container assembly, comprises a container body, including an inner wall and an outer wall coupled at a top of the container body and separated by a vacuum gap, and a lid that is reversibly attachable to the container body. The lid includes a vacuum insert; and a sleeve encompassing the vacuum insert, the sleeve configured to facilitate attachment of the lid to the container body, and further configured to generate a seal between the vacuum insert and the inner wall of the container body such that a base of the vacuum insert is exposed to a central cavity of the container body when the lid is fully attached to the container body. In this way, the entire central cavity may be surrounded by vacuum insulation, thus improving the thermal properties of the insulated container assembly.
