Abstract
An apparatus for magnetically sealing a cover of a beverage container comprises a body having an opening, at least a first magnetic member of a first polarity disposed on at least a first portion of the body and a second magnetic member of a second polarity, substantially opposite the first polarity, disposed on at least a second portion of the body, the first magnetic member magnetically retaining the second magnetic member in first and second positions, independent of mechanical assistance, to expose at least a portion of the opening to allow fluid flow to and from the container when in the first position and sealingly occlude the opening to prevent spillage when in the second position.
