Abstract

A reclosable plastic bag comprises first and second opposing body panels, a zipper, a slider, and a grab tab. The opposing body panels are joined to each other along a pair of sides and a bottom bridging the pair of sides. The zipper extends along a mouth formed opposite the bottom. The slider is slidably mounted to the zipper for movement between a closed position and an open position. Movement of the slider is effectuated using a grab tab extending upward from the slider. In one embodiment, first and second upstanding panels extend upwardly from the respective first and second body panels and form a pocket containing the zipper and the slider. The grab tab on the slider extends upwardly toward or above an upper end of the pocket so as to be easily graspable.

Claims

1. A reclosable plastic bag, comprising:

first and second opposing body panels joined to each other along a pair of sides and a bottom bridging said pair of sides;

a zipper extending along a mouth formed opposite said bottom;

a slider slidably mounted to said zipper for opening and closing said zipper;

a grab tab extending upward from said slider and adapted to be grasped by a user for effectuating movement of said slider along said zipper;

first and second upstanding panels extending upwardly from respective said first and second body panels and being joined to each other to encapsulate said slider and said grab tab in a pocket, said first and second upstanding panels including one or more breakable lines of weakness for gaining access into said pocket, said grab tab extending above one or more of said breakable lines of weakness.

2. The reclosable plastic bag of claim 1 wherein said breakable lines of weakness are generally linear.

3. The reclosable plastic bag of claim 1 wherein said grab tab includes one or more contours adapted to ease grasping by a user.

4. The reclosable plastic bag of claim 1 wherein said grab tab is rectangular.

5. The reclosable plastic bag of claim 1 wherein said grab tab is semi-elliptical.

6. The reclosable plastic bag of claim 1 wherein said breakable lines of weakness are perforated lines.

7. The slider structure of claim 1 wherein said first and second lines of weakness are score lines.

8. The slider structure of claim 1 wherein said first and second lines of weakness are thinned lines.

9. A reclosable plastic bag, comprising:

first and second opposing body panels joined to each other along a pair of sides and a bottom bridging said pair of sides;

a zipper extending along a mouth formed opposite said bottom;

a slider slidably mounted to said zipper for opening and closing said zipper;

a grab tab extending upward from said slider and adapted to be grasped by a user for effectuating movement of said slider along said zipper; and

first and second upstanding panels extending upwardly from respective said first and second body panels, each of said first and second upstanding panels including opposing ends, the opposing ends of said first upstanding panel being connected to the respective opposing ends of said second upstanding panel to form a pocket in which said slider is captured, said first and second upstanding panels being integrally formed with respective ones of said first and second body panels.

10. The reclosable plastic bag of claim 9 wherein said grab tab is transverse to a direction of slider movement.

11. The reclosable plastic bag of claim 9 wherein said grab tab is hourglass-shaped.

12. A method of accessing the contents of a bag having a zipper with a slider and upstanding panels extending upwardly from said zipper, comprising:

removing upper portions of said upstanding panels to form an open pocket;

grasping above said open pocket a grab tab extending upwardly from said slider; and

moving said grab tab to open said zipper.

13. The method of claim 12 wherein removing said upper portions of said upstanding panels comprises tearing off said upper portions along pre-formed lines of weakness.
