Description: |
| The patent deals with "self-venting" provisions for metal hot water bottles to deal with the tendency of partially filled metal hot water bottles to collapse as the contents cool.
Marketed as the UNIVERSAL Hot Water Bottle. The shape of these containers leads to mis-identification as military canteens. |
