Abstract: A drive unit that is movable between an unfired and a fired position. The drive unit comprises a handle member, a first drive gear having a first axis of rotation, and a second drive gear, engaged to the first drive gear at a mesh point, and having a second axis of rotation. The mesh point moves with respect to the axes of rotation as the handle member moves from the unfired position to the fired position. The drive unit drives an implement only when it is moved from the unfired position to the fired position.

Abstract: A device for storing food and displaying food for service includes a base with a side wall extending upwardly from the base and a puck assembly removably disposed therein. The puck assembly has a generally flat plate surface on one side and a functional surface with a plurality of food receptacles formed thereon on the opposite side, a sealed cavity disposed between the plate surface and the functional surface, and a cooling substance disposed in the sealed cavity. A food tray is disposed proximate the puck assembly, and a lid shaped to alternatively fit on the top surface of the wall of the base and to fit on the external surface of the bottom of the base such that the base can nest in the lid. The device provides a multitude of optional arrangements of these elements to provide maximum flexibility to the user.
