ABSTRACT:
A reclosable plastic bag (10) having two panels (15) of plastics sheet or film joined to, or integral with, each other, or a combination of both, to define a bag with an opening (13), with separable fastening means (14) of one or more interengagable elongate fib/groove configurations (14a,14b) are provided to close the opening (13). A slider (100) is positioned in straddling relationship to the fastening means, and includes a support member (111) over-lying the opening to the bag and straddling the fastening means, and also carrying a separating finger (112) to engage with and separate the fastening means when the slider is moved to a first end of the fastening means in a bag opened condition, and a pair of legs (113) extending from said support member to force the fastening means into interengaging relationship when the slider is moved to a second end of said fastening means in a bag closed condition. Flanges (119) on the legs extend beneath the fastening means to retain the slider on the bag. The edges (19) of the panels of the bag adjacent the second end of the fastening means are bonded together with a portion thereof between the bonding and said fastening means being crimped to define a torturous path (20a) between the panels into which path the separating finger (112) the slider is received to be gripped by the portions of the panels on either side of the torturous path to thereby retain the slider in the bag closed condition.
