Abstract

A flexible, reclosable package having a reclosable zipper construction openable and closeable by a slider device, and a tamper-evident structure disposed over the zipper construction to provide indication whether access has been gained to the interior of the package. A second tamper-evident structure may be disposed between the zipper construction and the package interior. This second structure may be a web or a peel seal.

Claims (65)

1. A recloseable package comprising:

(a) polymeric film folded and sealed to define a package having an interior;

(b) a zipper closure comprising first and second mating profiles; the zipper closure being secured to the package to provide selective access to the package interior;

(c) a slider device operably mounted on the zipper closure and being moveable along the zipper closure;

(i) the slider device being constructed and arranged to interlock and disengage the first mating profile and the second mating profile in response to movement of the slider device along the zipper closure;

(d) the package having a top seal and a first tamper-evident structure;

(i) the top seal being adjacent to the zipper closure;

(ii) the first tamper-evident structure encasing a first portion of the zipper closure; and

(iii) the first tamper-evident structure defining an opening exposing the slider device and a second portion of the zipper closure;

(A) the opening comprising a shape entirely defined and entirely surrounded by the first tamper-evident structure; and

(e) a second tamper evident-structure positioned adjacent to the zipper closure.

2. A recloseable package according to claim 1 wherein:

(a) said polymeric film folded and sealed to define a package includes:

(i) first and second panel sections secured together to define a top edge; a bottom edge; and first and second side edges extending between the top edge and the bottom edge.

3. A recloseable package according to claim 2 wherein:

(a) said top seal is adjacent to said top edge.

4. A recloseable package according to claim 3 wherein:

(a) said second tamper-evident structure is positioned between the zipper closure and the bottom edge;

(i) the second tamper evident-structure being between the first panel section and the second panel section; and

(ii) the second tamper evident-structure extending from the first side edge to the second side edge.

5. A recloseable package according to claim 4 wherein:

(a) said polymeric film includes an area of weakness extending between the first and second side edges of the package.

6. A recloseable package according to claim 1 wherein:

(a) the opening has a perimeter defined by end edges of the first tamper-evident structure; and

(b) the slider device is spaced not more than 2 cm from at least a portion of the opening perimeter.

7. A recloseable package according to claim 6 wherein:

(a) at least selected portions of the perimeter of the opening are sealed together.

8. A recloseable package according to claim 1 wherein:

(a) the opening in the first tamper-evident structure comprises an irregular shape.

9. A recloseable package according to claim 2 wherein:

(a) the opening in the first tamper-evident structure comprises an irregular shape.

10. A recloseable package according to claim 6 wherein:

(a) the opening in the first tamper-evident structure comprises an irregular shape.

11. A recloseable package according to claim 1 wherein:

(a) the opening in the first tamper-evident structure comprises a circle.

12. A recloseable package according to claim 1 wherein:

(a) the second tamper-evident structure comprises a peel seal.

13. A recloseable package according to claim 1 wherein:

(a) the first portion of the zipper closure comprises at least 80% of the zipper closure.

14. A recloseable package according to claim 1 wherein:

(a) the first portion of the zipper closure comprises at least 90% of the zipper closure.

15. A recloseable package according to claim 4 wherein:

(a) the opening has a perimeter defined by end edges of the first tamper-evident structure;

(b) the slider device is spaced not more than 2 cm from at least a portion of the opening perimeter; and

(c) the opening in the first tamper-evident structure comprises an irregular shape.

16. A recloseable package according to claim 15 further comprising:

(a) food in the package interior.

17. A method of making a package; the method comprising:

(a) providing a package body having an interior surface and defining a package interior; the package body having first and second sides, a top, and a bottom;

(b) attaching the zipper closure to the interior surface of the package body to extend between the first and second sides; the zipper closure having a slider device operably mounted thereon;

(c) forming a first tamper-evident structure over a portion of the zipper closure with the package body by:

(i) sealing the package body along the top to form a top seal and encase the zipper closure; the zipper closure being positioned between the top seal and the bottom;

(ii) forming an opening having an irregular shape in the first tamper-evident structure to expose the slider device in a position adjacent to the first side;

(A) the opening being entirely defined by the tamper-evident structure;

(B) the opening having a perimeter defined by end edges of the first tamper-evident structure; and

(C) the slider device being spaced not more than 2 cm from at least a portion of the opening perimeter; and

(d) providing a second tamper-evident structure between the zipper closure and the bottom.

18. A method of making according to claim 17 wherein:

(a) said step of providing a second tamper-evident structure includes providing a peel seal between the zipper closure and the bottom.

19. A method of making according to claim 17 wherein:

(a) said step of providing a second tamper-evident structure includes providing a web extension between opposing walls of the package body.

20. A method of making according to claim 17 further comprising:
