Abstract
A reclosable plastic bag (10a, 10b) having a front wall (12) and a rear wall (14), opposed sides (16, 18) and an open top end (24) has a zipper (22) extending across the front and rear walls (12, 14) from side to side at the bag top. The zipper (22) includes first and second profiles (17, 19) having mating interlocking portions (26, 28). A camber inducing member (30, 32) is provided at the bag top on at least one of the profiles (17, 19) or the front and rear walls (12, 14) to urge the top end of the front wall (12) away from the top end of the rear wall (14) when the mating interlocking portions are disengaged from one another.
