Abstract
Abstract A cup lid for use with disposable cups or the like, including a circular recess in the cup lid centrally thereof for receiving the bottom of a cup to permit vertical stacking of a plurality of cups having the cup lid thereon. The cup lid further includes an annular recess at the periphery thereof, including indentations spaced angularly thereabout on the exterior thereof and extending for part of the depth of the annular recess for locking the top of a cup within the annular recess. A hat-shaped section is provided between the circular recess and annular recess of the lid for receiving the bottom of a corresponding disposable cup with the lid inverted and used as a coaster. The circular recess may be provided with an offset portion adjacent the bottom thereof to provide a reduced diameter bottom section for snugly receiving the bottom of a corresponding cup with the lid in use as a cup holder. Angularly spaced apart radially extending ridges are provided between the hat-shaped section and the annular recess to provide lid strength and inhibit fluid movement around the lid and angularly spaced apart axially extending ribs are provided on the hat-shaped section to further space a portion of the hat-shaped section from a cup bottom position therein, thereby providing a cool gripping surface for the lid in use as a cup holder.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
249 words
A combination disposable coaster and cup lid comprising a circular member including an annular recess around the radially outer periphery thereof which in cross section is arcuate and has a portion which is substantially a semicircle for receiving the lip of a corresponding cup with the coaster and cup lid in use as a cup lid, said coaster and cup lid further including a hatshaped section concentric with and spaced radially inwardly of the annular recess and opening in the same direction as the annular recess and a depressed circular recess in the top of the lid opening radially inwardly of and concentric with both the annular recess and hat-shaped section and opening in the opposite direction therefrom for receiving the bottom of an associated cup to facilitate stacking of a plurality of associated cups with the coaster and cup lid in use as a cup lid and forming a U-shaped cross section portion with the hat-shaped section providing an annular ring for supporting the coaster and cup lid and providing a raised platform on which the corresponding cup may be positioned with the coaster and cup lid in use as a coaster and also providing a second annular recess between the outer wall of the hat-shaped section and the outer wall of the depressed circular portion whereby liquid spilled in the combination coaster cup lid with the coaster and cup lid in use as a coaster is retained in the coaster away from the bottom of the cup.
Claim 2
Dependent Claim
249 words
A combination disposable coaster and cup lid comprising a circular member including an annular recess around the radially outer periphery thereof which in cross section is arcuate and has a portion which is substantially a semicircle for receiving the lip of a corresponding cup with the coaster and cup lid in use as a cup lid, said coaster and cup lid further including a hatshaped section concentric with and spaced radially inwardly of the annular recess and opening in the same direction as the annular recess and a depressed circular recess in the top of the lid opening radially inwardly of and concentric with both the annular recess and hat-shaped section and opening in the opposite direction therefrom for receiving the bottom of an associated cup to facilitate stacking of a plurality of associated cups with the coaster and cup lid in use as a cup lid and forming a U-shaped cross section portion with the hat-shaped section providing an annular ring for supporting the coaster and cup lid and providing a raised platform on which the corresponding cup may be positioned with the coaster and cup lid in use as a coaster and also providing a second annular recess between the outer wall of the hat-shaped section and the outer wall of the depressed circular portion whereby liquid spilled in the combination coaster cup lid with the coaster and cup lid in use as a coaster is retained in the coaster away from the bottom of the cup.
Claim 3
Dependent Claim
105 words
Structure as set forth in claim 1 and further including an offset in the outer wall of the depressed circular recess providing a portion of smaller diameter at the bottom of the depressed circular recess and an annular ledge centrally of the depressed circular recess in the top of the coaster and cup lid for receiving the outer periphery of the bottom of an associated cup for stacking, and a corresponding annular ledge on the otHer side of the coaster and cup lid for receiving the periphery of the bottom of the associated cup with the coaster and cup lid in use as a coaster.
Claim 4
Dependent Claim
59 words
Structure as set forth in claim 2 and further including angularly spaced apart axially extending ribs on the coaster and cup lid between the annular recess around the outer periphery of the coaster and cup lid and the hat-shaped section for strengthening the lid and providing a cool gripping surface when the lid is used as a cup holder.
Claim 5
Dependent Claim
68 words
Structure as set forth in claim 2 and further including a plurality of radially extending indentations angularly spaced about the outer edge of the annular recess around the outer periphery of the coaster and cup lid and extending thereinto for at least part of the depth of the annular recess to facilitate securing of the coaster cup lid to the corresponding cup lip in use as a lid.
Claim 6
Dependent Claim
63 words
Structure as set forth in claim 2 and further including angularly spaced apart ridges extending radially inwardly of the lid from the annular recess around the outer periphery of the coaster and cup lid to the hat-shaped section for strengthening the lid and inhibiting movement of liquid around the circumference of the lid with the coaster cup lid in use as a lid.
