Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
134 words
A beater comprising a whisk assembly, a bowl, a lid for closing the bowl, a shell mounting said whisk assembly therein and which is in turn mounted for rotation inside the bowl, a drive shaft, a mechanical link between said drive shaft and the shell, the whisk assembly being driven by the shaft, characterized in that a resilient member is disposed between the shell and the mechanical link, and including a sealing ring and a seat for creating a seal between said drive shaft and said shell, said resilient member being compressed by pressure from the lid closing said bowl and causing downward translation of the shell, which causes movement of the sealing ring away from its seat, and an unlocking of the lid causing the seat to be pressed against the sealing ring.
Claim 2
