Lid for Glasses

Abstract

A concave lid including a depression, such as a notch compatible with a user's finger or thumb to apply pressure on the concave lid toward a glass. The depression may include anti-slip ridges to keep the user's fingertip from slipping when pressure is applied by the user. The concave lid has a portion for indicia that is readable from the outer surface of the concave lid. The concave lid may include a textured portion on its lower surface, such as a band of texture, to create friction and prevent the concave lid from slipping with respect to the glass. The concave lids are preferably stackable and made of clear plastic or glass.

What is claimed is: 
     
         1 - 6 . (canceled) 
     
     
         7 . A concave lid adapted for use with a glass, the concave lid including a depression with anti-slip ridges, the depression has a flat edge and a remainder of the depression is a partial oval that corresponds to the size and shape of a fingertip, wherein the concave lid is adapted for the user to apply pressure on the depression with the user's index finger to hold the concave lid on a rim of the glass. 
     
     
         8 . The concave lid of  claim 7  wherein the concave lid is stackable with other concave lids when depressions of each concave lid are aligned. 
     
     
         9 . The concave lid of  claim 7  wherein the depression is centered in the concave lid. 
     
     
         10 . The concave lid of  claim 7  wherein the depression is adjacent to an edge of the concave lid with the flat edge at a base of the depression closest to the edge of the concave lid. 
     
     
         11 . The concave lid of  claim 7  wherein the flat edge forms a lip that is part of the depression, 
     
     
         12 . The concave lid of  claim 9  that is can be balanced on a bottom portion of the depression so that when resting on a surface with an outer edge upward, only the bottom portion of the depression touches the surface so that a lower surface surrounding the depression would not touch the surface. 
     
     
         13 . A stackable concave lid adapted for use with a glass, a depression centered in the concave lid including the depression with anti-slip ridges, the depression has an edge forming a lip and a remainder of the depression is substantially oval that corresponds to the size and shape of a fingertip, wherein the concave lid is adapted for the user to apply pressure on the depression with the user's finger to hold the concave lid as seated on a rim of the glass. 
     
     
         14 . The stackable concave lid of  claim 13  that is can be balanced on the depression so that when resting on a surface with an outer edge upward, only the depression touches the surface so that a lower surface surrounding the depression would never not touch the surface wherein, the lower surface of the concave lid that touches the glass does not touch the surface so contaminants of the surface would not transfer to the lower surface surrounding the depression. 
     
     
         15 . The stackable concave lid of  claim 13  wherein the concave lid is made of a same material as the glass. 
     
     
         16 . The concave lid of  claim 12  wherein the outer edge is circular so the concave lid is disc-shaped. 
     
     
         17 . The stackable concave lid of  claim 14  wherein the outer edge is circular. 
     
     
         18 . The concave lid of  claim 7  wherein the concave lid is a disc measuring 3.5 inches (88.9 mm) in diameter. 
     
     
         19 . The stackable concave lid of  claim 13  wherein the stackable concave lid is a disc measuring 3.5 inches (88.9 mm) in diameter. 
     
     
         20 . The concave lid of  claim 7  wherein a horizontal depth of the depression extends deeper than a concave curve of the concave lid, 
     
     
         21 . The stackable concave lid of  claim 13  wherein a horizontal depth of the depression extends deeper than a concave curve of the concave lid. 
     
     
         22 . The concave lid of  claim 7  wherein the depression is shaped as a boattail. 
     
     
         23 . The stackable concave lid of  claim 13  wherein the depression is shaped like a boattail, 
     
     
         24 . The concave lid of  claim 7  wherein the concave lid is made of transparent polymer, copolyester, or translucent glass. 
     
     
         25 . The stackable concave lid of  claim 13  wherein the stackable concave lid is made of transparent polymer, copolyester, or translucent glass.
