Slider for a plastic bag

Abstract

A slider ( 10 ) to be positioned in straddling relationship on a reclosable fastener means for a bag formed by a pair of plastic sheets having separable fastener means extending along an opening for the bag and including reclosable interlocking rib and groove profiles along the plastic sheets at said opening of the bag. The slider includes a support member ( 11 ), in use, overlying the opening to the bag and straddling the fastening means, and also carrying a separating finger ( 12 ) adapted, in use, to engage within and adapted to separate the fastening means when the slider is moved in one direction, and a pair of legs ( 13 ) depending therefrom to force the fastener means into interlocking relationship when the slider is moved in the opposite direction along the fastening means. A pair of foldable sidewalls or wings ( 15 ) are integrally hinged at ( 16 ) to a side edge of each of the legs and foldable relative to their associated leg, and means are provided to interlock the sidewalls with their associated legs, whilst ledges ( 20 ) on the foldable sidewalls or wings retain the slider on the bag and beneath the fastening means to prevent the slider from being laterally removed from beneath the fastening means.

1 . A slider to be positioned in straddling relationship on a reclosable fastener means for a bag formed by a pair of plastic sheets having separable fastener means extending along an opening for the bag and including reclosable interlocking rib and groove profiles along the plastic sheets at said opening of the bag, wherein the slider includes a support member, in use, overlying the opening to the bag and straddling said fastening means, and also carrying a separating finger adapted, in use, to engage within and adapted to separate said fastening means when the slider is moved in one direction, and a pair of legs depending therefrom to force said fastener means into interlocking relationship when the slider is moved in the opposite direction along said fastening means, and wherein means are provided to retain said slider on said bag and beneath said fastening means to prevent said slider from being laterally removed from beneath said fastening means.  
     
     
         2 . A slider as claimed in  claim 1 , wherein said slider also has at least one foldable sidewall or wing integrally hinged to a side edge of at least one leg and foldable relative to its associated leg, and means are provided to interlock said sidewall with its associated leg.  
     
     
         3 . A slider as claimed in  claim 1  or  2 , wherein the means to retain said slider on said bag is part of the, or each, said hinged sidewall.  
     
     
         4 . A slider as claimed in  claim 2  or  3 , wherein each said leg of the slider has a foldable sidewall associated therewith.  
     
     
         5 . A slider as claimed in  claim 3 , wherein each said sidewall carries the means to retain said slider on said bag and around said fastener means.  
     
     
         6 . A slider for opening and closing reclosable fasteners on plastic bags, substantially as hereinbefore described with reference to the accompanying drawings.
