Abstract

A foldable plastic slider for straddling relation with a plastic fastener includes first and second profiles. The straddling slider is adapted to close or open the fastener by movement therealong. The slider comprises a transverse support member, first and second legs, first and second separating fingers, and first and second wings. The transverse support member includes first and second opposing sides, an interior surface, and an outer surface. The first and second legs depend from the respective first and second opposing sides of the support member. The first separating finger extends from the interior surface of the support member. The first separating finger is adapted to open the first and second profiles. The second separating finger extends from the interior surface of the support member. The first and second wings are hingedly attached to the respective first and second opposing sides. The first and second wings have respective first and second openings for receiving the respective first and second legs. The first and second wings have respective first and second cross pieces. Each of the cross pieces includes a main body member and a latch. The first and second wings are folded relative to the support member and each of the latches engages one of the respective legs to install the slider on the fastener.

Dependent claims

A method of installing a foldable plastic slider onto a reclosable plastic bag having opposing body panels attached to each other along a pair of opposing sides and a bottom bridging the sides, a mouth formed opposite said bottom, and a reclosable fastener extending along said mouth, said fastener including a first track with a first profile and a second track with a second profile, said first and second profiles being releasably engageable to each other, said plastic slider being slidably mounted to said fastener, said method comprising:

providing a foldable plastic slider, the foldable plastic slider including
a transverse support member including first and second opposing sides, an interior surface, and an outer surface;
first and second legs depending from said respective first and second opposing sides of said support member and extending downward from the interior surface of the support member;
a first separating finger extending from said interior surface of said support member, said first separating finger adapted to open the first and second profiles;
a second separating finger extending from said interior surface of said support member;
and
first and second wings hingedly attached to said respective first and second opposing sides, said first and second wings having respective first and second openings for receiving said respective first and second legs, said first and second wings having respective first and second cross pieces, each of said cross pieces including a main body member and a latch, said first and second wings being folded relative to said support member and each of said latches engaging one of said respective legs to install said slider on said fastener;
placing said transverse support member on said plastic fastener with said first and second separating fingers between said first and second tracks and said first and second depending legs outside said respective first and second tracks such that said respective first and second tracks separate said first and second separating fingers from said respective first and second legs;
rotating said first and second wings downward toward a bottom of said reclosable bag until each of said latches engages one of said respective legs;
and
pressing said first and second wings until each of said latches snaps into engagement with one of said respective shoulders of said respective leg.
