Abstract
Abstract A bottle cap forming an integral measuring cup and bottle closure, including a cup having a base and sidewall, and a closure member extending from the base. The cup sidewalls are graduated to indicate volume levels. The closure member may extend upwardly, interiorly of the cup, may be solid or hollow, and may taper upwardly to facilitate insertion into the mouth of the bottle. Alternately, the hollow closure may be provided with threads for use with a bottle requiring a threaded closure. The closure member may also extend downwardly, and the cup may be provided with a skirt.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
101 words
A bottle cap including an integral measuring cup comprising a base having a periphery, a sidewall extending upwardly from said periphery forming a cup having at least one graduation on the interior wall of said cup indicating a volume level, and a closure member extending from the base and adapted to seal the opening of a bottle, said closure member including a plurality of spaced apart disk-shaped wing members extending parallel with said base, said wing members being adapted to deform when said closure member is inserted into a bottle to hold the cap on the bottle and prevent spillage therefrom.
Claim 2
Dependent Claim
101 words
A bottle cap including an integral measuring cup comprising a base having a periphery, a sidewall extending upwardly from said periphery forming a cup having at least one graduation on the interior wall of said cup indicating a volume level, and a closure member extending from the base and adapted to seal the opening of a bottle, said closure member including a plurality of spaced apart disk-shaped wing members extending parallel with said base, said wing members being adapted to deform when said closure member is inserted into a bottle to hold the cap on the bottle and prevent spillage therefrom.
Claim 3
Dependent Claim
22 words
A cap as recited in claim 1 in which the graduation comprises an annular notch formed in the sidewall of the cup.
Claim 4
Dependent Claim
46 words
A cap as recited in claim 1 in which said closure member extends downwardly from said base, said cup further comprising a skirt extending downwardly to surround said closure member, said closure member and said skirt being spaced apart to accommodate the neck of the bottle.
Claim 5
Dependent Claim
37 words
A cap as recited in claim 3 in which said closure member comprises a core member and said wings comprise a plurality of flexible disks extending from said core member, said disks being parallel to said base.
Claim 6
Dependent Claim
36 words
A cap as recited in claim 4 in which said base includes a downwardly-projecting stud and said core member includes a bore of sufficient diameter to facilitate the core member being frictionally retained by said stud.
Claim 7
Dependent Claim
39 words
A cap as recited in claim 5 in which the free end of said stud includes a recess having a rim, the rim being deformable to permit its being flared to further retain said closure member on said stud.
Claim 8
Dependent Claim
42 words
A cap as recited in claim 5 formed by heating the core member to enlarge the bore, slipping the core member over said stud and cooling core member to shrink the bore, the core member then being frictionally retained by said stud.
Claim 9
Dependent Claim
126 words
A bottle cap including an integral measuring cup comprising a base having a periphery, a sidewall extending upwardly from said periphery forming a cup having at least one graduation on the interior wall of said cup indicating a volume level, and a closure member extending from the base and adapted to seal the opening of a bottle, said closure member including a support member coaxial with said cup and a plurality of relatively thin wing members circumferentially spaced apart and attached to the side of and extending radially from said support member and extending longitudinally along said support member coaxial with said cup, said wing members being adapted to deform when said closure member is inserted into a bottle to hold the cap on the bottle.
Claim 10
Dependent Claim
126 words
A bottle cap including an integral measuring cup comprising a base having a periphery, a sidewall extending upwardly from said periphery forming a cup having at least one graduation on the interior wall of said cup indicating a volume level, and a closure member extending from the base and adapted to seal the opening of a bottle, said closure member including a support member coaxial with said cup and a plurality of relatively thin wing members circumferentially spaced apart and attached to the side of and extending radially from said support member and extending longitudinally along said support member coaxial with said cup, said wing members being adapted to deform when said closure member is inserted into a bottle to hold the cap on the bottle.
Claim 11
Dependent Claim
17 words
A cap as recited in claim 8 in which said closure member extends interiorly of said cup.
Claim 12
Dependent Claim
28 words
A cap as recited in claim 8 in which said support member comprises a resilient frusto-conical member having a base attached to the base of the measuring cup.
