Abstract

A zipper assembly (100) for an enclosure (10) includes a flange (108, 110) having an interlocking side (130, 132) and an opposite panel side (134, 136). The interlocking side has interlocking members (112, 114) configured to releasably engage and release from other interlocking members to alternate between closed and open states of the enclosure. The panel side is configured to be sealed to panels (14, 16) of the enclosure to affix the zipper assembly to the enclosure. The zipper assembly includes posts (40) protruding from the panel side of the flange. The posts are configured to prevent compression of the posts and maintain a spatial separation between the panel side of the flange and the interlocking side of the flange while the zipper assembly is wound onto a supply roll. The posts are configured to collapse upon compression of the posts during sealing of the panel side of the flange to the panels of the enclosure to allow the panel side of the flange to be sealed to the panels (14, 16).
