Child resistant slider, zipper closure system using slider, and methods of use
A child resistant slider includes a top member and a pair of spaced legs depending from the top member. At least a first leg of the spaced legs has a first tang projecting laterally away from a remaining portion of the first leg and a remaining portion of the slider. The first tang has a separator plow. The tang can be movable to move the first plow into a position to separate interlocked male and female tracks of a zipper closure. In other examples, both legs include a projecting tang having a separator plow.
1. A slider for a recloseable package comprising:
a first end and an opposite second end defining a longitudinal length therebetween;
a top member and a pair of spaced apart first and second legs depending from the top member, each of the first leg and second leg having an inwardly facing hook opposite the top member;
at least a first outwardly facing tab having a fixed end adjacent the first end and secured to the first leg, and a deflectable section unattached along the longitudinal length toward the second end and extending away from the second leg; and
a first separator plow located at the deflectable section of the first tab and facing away from the top member and in a direction toward the hooks.
2. The slider of claim 1 wherein the first plow is at an end of the deflectable section of the first tab.
3. The slider of claim 1 wherein the first plow has a triangle-shaped cross-section.
4. The slider of claim 1 wherein the slider defines an open volume and includes internal surfaces spaced sufficiently close together to press opposing interlocking profiles into an interlocking relationship.
5. The slider of claim 4 wherein the first and second legs define the open volume and the internal surfaces.
6. The slider of claim 4 wherein the first tab is moveable to locate the first plow into the open volume between the legs.
7. The slider of claim 4 further including:
a second outwardly facing tab having a second fixed end secured to the second leg and having a second deflectable section extending away from the first leg; and
a second separator plow located at the second deflectable section of the second tab and facing away from the top member and in a direction toward the hooks.
8. The slider of claim 7 wherein both the first tab and second tab are selectively moveable to locate the first plow and second plow toward each other into the open volume between the legs.
9. The slider of claim 7 wherein the second plow is at an end of the second deflectable section.
10. The slider of claim 7 wherein the second plow has a triangle-shaped cross-section.
11. The slider of claim 1 wherein the slider is molded as a single piece of plastic.
12. A flexible package using the slider of claim 1 , the package comprising:
(a) first and second opposing panels defining a three-edged containment section with an interior and a mouth providing access to the interior;
(b) a reclosable zipper closure along the mouth with a male track and a female track having complementary profiles for interlocking and unlocking, wherein one of the tracks is along the first panel, and the other of the tracks is along the second panel; and
(c) wherein the slider is slidably located on the zipper closure with the legs straddling the tracks, and wherein the first tab is moveable to locate the first plow in a position to separate the male and female tracks as the slider is moved along the zipper closure.
13. The flexible package of claim 12 wherein:
(a) the slider further includes a second outwardly facing tab having a second fixed end secured to the second leg and having a second deflectable section extending away from the first leg; and a second separator plow located at the second deflectable section of the second tab and facing away from the top member and in a direction toward the hooks; and
(b) both the first tab and second tab are moveable to locate the first plow and second plow adjacent each other in a shape to separate the male and female tracks as the slider is moved along the zipper closure.
14. The flexible package of claim 13 wherein each of the first plow and second plow are triangle-shaped, and wherein each of the first plow and second plow are insufficiently sized to separate the male and female tracks alone without the other.
15. The flexible package of claim 12 wherein the first and second panels comprise polymeric, plastic film.
16. The flexible package of claim 15 wherein the three-edged containment section includes first and second side edges sealed together and a bottom folded edge opposite of the mouth.
17. The flexible package of claim 12 further including a notch located in the male and female tracks.
