Claim 6:
7. The zipper assembly of claim 1, further comprising:
a slider having opposite first and second ends and opposite first and second sidewalls that each extend from the first end to the second end, the slider having a space between the first and second sidewalls, the space having a shape through which the first and second zipper members move,
wherein, in an absence of an additional manual force to push the first and second sidewalls of the slider toward each other, the first and second sidewalls provide an insufficient force to separate the first and second zipper members from each other and the additional manual force must be provided to the first and second sidewalls to pivot the first zipper member about a fulcrum on the second zipper member to separate the first zipper member from the second zipper member,
the second end of the slider having elements for interlocking the profile protrusions of the first zipper member and the second zipper member in response to motion of the slider along the first zipper member and the second zipper member in a closing direction, the slider formed of a flexible material that is configured to be manually pressed to urge the first and second sidewalls of the slider together to separate the profile protrusions of the first zipper member and the second zipper member.
