Food processing apparatus
摘要:
The center portion of the lid for a high speed food processing apparatus is flexible, preferably transparent and is supported by a rigid lid support member. The outer portion of the lid is stiff so that the center portion acts as a spring when compressed by the support member onto the edge of the bowl of the food processing apparatus.
