Abstract: A drink container and plug lid for use therewith. The lid has an upper member and a lower member with a ring seal positioned therebetween and radially outwardly stretchable from an initial diameter to a larger sealing diameter in response to an actuator moving the upper and lower members together to place the ring seal in fluid-tight sealing engagement with the container body. Moving the upper and lower members apart allows the radially outward stretched ring seal to move from the sealing diameter to the initial diameter whereat it is out of fluid-tight sealing engagement with the container body.

Abstract: Provided are ceramic compositions and containers, in each case comprising a ceramic (e.g., porcelain, stoneware, porcelain, or ceramic composition having properties of both) composition to which an amount of alumina has been added to provide a ceramic composition comprising 20% to 25% (wt./wt.) alumina, preferably about 22% (wt./wt.) alumina, providing a stronger material, such that wall thicknesses (e.g., of double-walled beverage containers) can be reduced or minimized to create a lighter double-walled ceramic container. The disclosed containers have a chemical and porous structure suitable for a wide array of stoneware glazes, and display water absorption rate properties comparable to stoneware. Methods of making same are provided.

Abstract: A drink container and three position plug lid for use therewith. The lid includes a tubular seal with a flexible perimeter seal wall attached between upper and lower seal carriers, a lifter member attached to the lower seal carrier and a cam member to control movement of the lower seal carrier relative to the upper seal carrier and thereby laterally flex and axially move the perimeter seal wall and move the lid between closed and opened positions where the lid is retained within the drink container against removal, and a removal position permitting removal of the lid for washing the lid and drink container.
