Abstract
A closure assembly useable with a pouch or bag includes an elongate seal assembly and a slider. The seal assembly includes upper and lower interlocking profiles and a rib disposed between the interlocking profiles on at least one side of the seal assembly. The slider includes forward closure bars at a first end and a separator finger and lower closure bars adjacent to an opposing second end. The forward and lower closure bars occlude the upper and lower interlocking profiles. The separator finger extends between the upper interlocking profiles and presses outwardly against the rib to de-occlude the lower interlocking profiles. The lower interlocking profiles can be occluded along substantially an entire length thereof. The slider also includes a retention plate and pressing members, which operatively retain the slider on the seal assembly and may increase the opening force created by the separator finger against the rib.
