Improved profile and adjacent rib-type closure element for reclosable thermoplastic bags.

摘要

A closure member for a reclosable plastic bag, including a longitudinally-extending profile (12) interlockable with an opposing longitudinally-extending profile of a second closure member, and at least one longitudinally-extending ribs (14) located adjacent and generally parallel to at least one profile on at least one side of the profile, with the rib being characterized in cross-section (22) by a lower generally triangularly-shaped portion and by an upper bulbous portion (24) defined generally at an apex of the lower generally triangularly shaped portion.
