Abstract
A novel zipper profile is disclosed in which the cross-sectional shape of the zipper is such that it can be closed most easily by pressing the bottom together first, then rolling it closed toward the top. The novel slider is shaped so that it operates in this fashion on the zipper profile, holding the top open while it presses the bottom together, then presses the top together while the slider passes by.
