US Patent 10278525 Drinking vessel comprising a compensating body

A drinking vessel has a drink container with a body that compensates for changes in the liquid level in the drink container. The compensating body includes an elastic component which, under the influence of weight forces of a liquid volume, enlarges its shape, i.e. the volume of the compensating body. When the acting weight forces cease, the compensating body returns to a smaller original shape. There is no need for a sliding-movement-based sealing action of the compensating body in relation to the inner walls of the drink container. Therefore, the user does not have to first put the drink container down in order for the liquid level to stabilize.
