Abstract

A reclosable bag is formed of walls defining a closure with a mouth. Adjacent to the mouth the bag is formed with interlocking male and female profiles for selectively opening and closing the mouth. Beams are also provided on the inner surfaces of the walls positioned to insure that the male and female profiles do not open inadvertently. Finger guide members may also be provided above the profiles to insure that the bag is closed properly.
