The second strip includes a flexible, magnetic flap that is configured to repel the first strip and disable the magnetic attraction between the first and second strips based on the position of the slider. In operation, as the slider moves proximally along the second strip, the flap moves away from the first strip, thereby removing the repulsive force against the first strip and allowing the first and second strip to connect and close the zipper. Similarly, as the magnetic slider moves distally along the second strip, the flap moves back towards the first strip, thereby renewing the repulsive force against the first strip and allowing the first and second strips to disconnect and open the zipper. ## Claims ### Claim 1 A non-interlocking magnetic zipper comprising: a first magnetic strip having proximal and distal ends and including a first tape and a first link; a second magnetic strip having proximal and distal ends and including a second tape and a second link; and a magnetic slider connected between the first strip and the second strip, the magnetic slider being shaped to receive the second magnetic strip;
