Abstract
A reclosable zipper having a first profile interlockable with a second profile is provided. The profiles include interlocking members which engage to form a vacuum seal when the profiles are interlocked. To provide resistance to product side separation forces, one of the profiles is additionally provided with an asymmetrical arrow-shaped member which interlocks with a groove element on the other profile so as to make it more difficult to open the zipper from the product side than the consumer side. To provide further resistance to product side separation forces, a hinge member may optionally be provided on one of the profiles.
