(under subclass 381) Subject matter including two or more zippers* which are distinct from each other.
(1) Note. The zippers* are considered distinct if at least (a) there are two distinct sets (i.e., two opposed pairs), of interlocking surfaces which are either noncolinear or if collinear have a structural member preventing movement of a common sliding device along both sets of surfaces, and (b) the sets of interlocking surfaces are either operated by independently movable sliding devices or a sliding device
which connects two distinct surface camming portions together which each operate on a different one of the sets.
