Abstract

A child resistant zipper closure for a plastic bag includes a zipper closure having a hood arrangement that includes at least a non-removable hood section in covering relation to a first portion of the zipper closure. There can be slider to open and close the closure, and the non-removable hood section will be sized to accommodate the slider. The hood arrangement can include a removable section to expose the zipper closure and allow access to the slider.

First claim

What is claimed is:

1. A child resistant slider zipper closure system comprising:
(a) a zipper closure selectively closable and openable;
(b) a slider operably mounted on the zipper closure to open and close the zipper closure, the slider having a body with an upper wall and first and second opposite side walls extending from the upper wall; and
(c) a non-removable hood covering the slider including the upper wall and first and second side walls of the slider such that no portion of the slider is physically exposed when the zipper closure is closed and covering the zipper closure at an opening initiation point of the zipper closure; the non-removable hood being a thermoplastic film extending only partially along the zipper closure from the opening initiation point and being sealed above the opening initiation point; the slider being movable from under the non-removable hood to slide along the zipper closure.

2. The slider zipper closure system of claim 1 , further comprising a removable hood portion.

3. The slider zipper closure system of claim 1 , wherein the non-removable hood is non-transparent.

4. A flexible package comprising the child resistant slider zipper closure system of claim 1 .

5. A zippered plastic bag having an openable and recloseable mouth, the bag comprising:
(a) first and second panels each having a top forming the mouth, a bottom, and first and second opposing sides;
(b) a zipper closure in proximity to the top of the first and second panels for interlocking to close the mouth and for unlocking to open the mouth;
(c) a slider oriented on the zipper closure to open and close the mouth by moving along the zipper closure, the slider having a body with an upper wall and first and second opposite side walls extending from the upper wall; and,
(d) a hood arrangement including at least a non-removable hood section in covering relation to the zipper closure at an opening initiation point of the zipper closure;
the non-removable hood section being a thermoplastic film extending only partially along the zipper closure from the opening initiation point and being sealed above the opening initiation point; the slider including the upper wall and first and second side walls being covered by the non-removable hood section such that no portion of the slider is physically exposed when the zipper closure is closed, and the slider being movable from under the non-removable hood section to slide along the zipper closure.

6. A bag according to claim 5 wherein:
(a) the hood arrangement includes an open position and a closed position;
(i) in the closed position, the hood arrangement covers an entire extension of the zipper closure; and
(ii) in the open position, the hood arrangement includes only the non-removable hood section covering the opening initiation point and less than the entire extension of the zipper closure.

7. A bag according to claim 6 wherein:
(a) the hood arrangement is secured to the first and second panels; and
(b) in the closed position, the hood arrangement includes a removable hood section and the non-removable hood section; the removable hood section being removable from the first and second panels to expose the zipper closure when removed.

8. A bag according to claim 7 wherein:
(a) the first and second panels are scored to permit removal of the removable hood section.

9. A bag according to claim 5 wherein:
(a) the non-removable hood section is sized to accommodate the slider.

10. A bag according to claim 5 wherein:
(a) the non-removable hood section is non-transparent.

11. A method of operating a zippered plastic bag having an openable and recloseable mouth; the method comprising:
(a) providing a zippered plastic bag having first and second panels each having a top forming the mouth, a bottom, and first and second opposing sides; a zipper closure in proximity to the top of the first and second panels for interlocking to close the mouth and for unlocking to open the mouth; a slider located on the zipper closure, the slider having a body with an upper wall and first and second opposite side walls extending from the upper wall; and a hood arrangement including at least a non-removable hood section in covering relation to the zipper closure at an opening initiation point of the zipper closure; the non-removable hood section being a thermoplastic film extending only partially along the zipper closure from the opening initiation point and being sealed above the opening initiation point; the slider including the upper wall and first and second side walls being covered by the non-removable hood section such that no portion of the slider is physically exposed when the zipper closure is closed, and the slider being movable from under the non-removable hood section to slide along the zipper closure; and
(b) opening the mouth by accessing the slider in the non-removable hood section and moving the slider along the zipper closure to unlock the zipper closure.

12. A method according to claim 11 wherein:
(a) the hood arrangement includes a removable hood section and the non-removable hood section; and
(b) the method further includes, before the step of opening the mouth, removing the removable hood section to expose a portion of the zipper closure.

13. A method according to claim 12 wherein:
(a) the step of removing the removable hood section includes tearing the removable hood section from the first and second panels along a score line.

14. A method according to claim 11 wherein:
(a) the step of moving the slider includes pinching the slider through the non-removable hood section.

15. A method according to claim 11 wherein:
(a) the step of moving the slider includes hooking the slider with a finger.

16. A method according to claim 11 wherein
(a) the step of moving the slider includes temporarily peeling back the non-removable hood section.
