Claim:
1. A slider for a zipper closure having a male track and a female track with complementary profiles for interlocking and unlocking; the slider comprising: (a) a base having a top member and a bottom member; the bottom member including first and second legs each terminating in an end wall; (b) a tab extending from the top member of the base and being spaced above the first and second legs of the base such that there is a cavity of open volume in between, the cavity being leg-free, sidewall-free, and free of other slider structure so that the open volume of the cavity extends from the end wall between the tab and the first and second legs; the tab being constructed and arranged to flex relative to the base about a pivot axis in a direction toward and away from the first and second legs; (c) a torpedo extending from a bottom surface of the tab and moving toward and away from the first and second legs with flexing of the tab; the torpedo being selectively moveable into a position to be between the male track and female track and result in separation of the interlocking profiles as the slider is moved in an opening direction along the zipper closure; and (d) the first and second legs having internal surfaces spaced sufficiently close together to press the profiles into interlocking relationship as the slider is moved in a closing direction along the zipper closure.
