Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
127 words
A toy with a spinable hollow body comprising a base, a plunger mounted on said base and depressable into said base, a hollow body portion supported by said base for spinning movement relative thereto, cooperating means on said plunger and body portion whereby the latter is spinable by the depression of said plunger into said base, and a closure for said body portion mounted on said base and movable from a position closing said body portion to a position opening said body portion, means for normally maintaining said closure in said closing position, said closure being openable by the depression of said plunger into said base, wherein said base includes a collar into which said plunger is depressable and said closure is slidably movable along said collar.
Claim 2
Dependent Claim
