Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
109 words
The combination of a circular container and a cover therefor having locking means for locking the cover to the container through rotational movement of the cover relative to the container, said container comprising a bottom wall having a side wall extending upwardly therefrom terminating in an outwardly extending rim, said cover comprising a top wall having a side wall depending therefrom terminating in an outwardly and downwardly extending flange adapted to seat on said container rim, holding means formed on the outer surface of the container side wall for gripping said container, and handle means formed on the outer surface of the cover side wall for grasping said cover.
Claim 2
Dependent Claim
109 words
The combination of a circular container and a cover therefor having locking means for locking the cover to the container through rotational movement of the cover relative to the container, said container comprising a bottom wall having a side wall extending upwardly therefrom terminating in an outwardly extending rim, said cover comprising a top wall having a side wall depending therefrom terminating in an outwardly and downwardly extending flange adapted to seat on said container rim, holding means formed on the outer surface of the container side wall for gripping said container, and handle means formed on the outer surface of the cover side wall for grasping said cover.
