1. A closure lid for capping the open top of a potable container, said lid having peripheral means for releasably sealingly engaging the lip of the container, a crown, and means providing a limited area in said crown having a group of small openings therein at least adjacent the periphery of the crown through which the potable in the container may be drunk through the lid, said crown being imperforate except at said area, the sizes and spacings of said openings inhibiting slosh waves in the potable, said lid having flutes which are expandable downwardly to open up upon application of manual pressure to the crown in the vicinity of the limited area whereby to form a depression to accommodate the nose of a person drinking the potable from the container through the lid, the side walls of the depression acting as baffles to further minimize slosh waves in the potable.

2. A lid as set forth in claim 1 wherein the flutes are parallel to a diameter of the crown.

3. A lid as set forth in claim 2 wherein the flutes are beyond the limited area.

4. A lid as set forth in claim 2 wherein the depression formed by pressing on the depressible area is in the shape of a trough.

5. A lid as set forth in claim 1 wherein the flutes are in the configuration of concentric circles.
