Abstract
A vacuum-drawing lid can include a base frame with a first one-way valve, a piston with a second one-way valve, and a cylindrical cam with a sinusoidal groove formed on an inner surface thereof to drive reciprocation of the piston as the cylindrical cam turns. Turning the cylindrical cam in a first direction can drive the piston to translate in a first direction and actuate the first valve. Turning the cylindrical cam in a second direction can drive the piston to translate in a second direction and actuate the second valve.
