Abstract

A reclosable package includes a tray, a top sheet, and a fastener. The tray has a well for receiving contents and a peripheral flange surrounding the well. The top sheet is attached to the peripheral flange. The fastener has two interlocking members, one attached to the peripheral flange and the other attached to the top sheet. A tamper-evident feature located on the package prevents access to the fastener and is connected thereto by one or two lines of weaknesses. In one embodiment with one or two lines of weakness in the top sheet, the fastener remains adjacent to the tray's peripheral flange, which is intact after the tamper-evident feature is removed by tearing along these lines of weakness. In a second embodiment with two lines of weakness, the tamper-evident feature, comprised of portions of the peripheral flange and the top sheet, is torn from the package along both lines of weakness.

Claims (50)

1. A reclosable package, comprising:

a tray having a well and a peripheral flange, said well receiving contents and said peripheral flange surrounding a perimeter of said well;

a top sheet attached to said peripheral flange with a generally continuous first seal extending around less than the perimeter of said well; said top sheet attached to an upper portion of said peripheral flange with a second seal separated from the first seal;

a fastener having first and second interlocking members, said first interlocking member being attached to said peripheral flange, and said second interlocking member being attached to said top sheet along an attachment region;

a recess defined in the flange of the tray, the recess configured to receive a slider;

a tamper-evident feature attached to said top sheet along a first line of weakness and attached to said peripheral flange of said tray along a second line of weakness, said tamper-evident feature being removable from said package to allow access to said fastener; and

wherein, in response to said tamper-evident feature being removed from said package, said fastener remains directly adjacent to said peripheral flange of said tray, and an entire length of said top sheet located below said first line of weakness and above said attachment region is foldable away from both said first and said second interlocking members of said fastener, while said first and said second interlocking members remain interlocked.

2. The reclosable package of claim 1 , wherein said slider operates to transition said fastener between an open position and a closed position, said slider resides in said recess when said fastener is moved toward said closed position.

3. The reclosable package of claim 2 , wherein said first and second lines of weakness are located above said slider.

4. The reclosable package of claim 1 , wherein said first and second lines of weakness are at substantially the same heights on said package.

5. The reclosable package of claim 1 , wherein said tray is substantially more rigid than said top sheet.

6. The reclosable package of claim 1 , wherein said peripheral flange includes a bottom, two sides, and said top, said fastener being located adjacent said top, one of said two sides including a peg hole for receiving a peg that allows the package to be displayed in a retail store.

7. The reclosable package of claim 1 , wherein said fastener includes a hermetic seal adjacent to said first and second interlocking members, said hermetic seal being broken after said tamper-evident feature is removed from said package.

8. A reclosable package, comprising:

a tray having a well and a peripheral flange, said well receiving contents and said peripheral flange surrounding a perimeter of said well, said peripheral flange having a top, two sides and a bottom;

a top sheet attached to said bottom and at least a portion of each of said sides of said peripheral flange with a generally continuous first seal extending around less than the perimeter of said well, said top sheet further being attached to said top of said peripheral flange with a generally continuous second seal, said first seal being spaced away from said second seal;

a fastener having first and second interlocking members, said first interlocking member being attached to said peripheral flange and said second interlocking member being attached to said top sheet; and

a tamper-evident feature attached to said top sheet along a first line of weakness and attached to one of said top sheet and said peripheral flange of the tray along a second line of weakness, said first and second lines of weakness being above said first seal, said tamper-evident feature being removable from said package along said lines of weakness to allow access to said fastener.

9. The reclosable package of claim 8 , wherein said fastener includes a hermetic seal adjacent to said first and second interlocking members, said hermetic seal being breakable by a consumer after said tamper-evident feature is removed from said package.

10. The reclosable package of claim 9 , wherein said hermetic seal is located below said first and second interlocking members.

11. The reclosable package of claim 8 , further including a hermetic seal extending generally parallel to said interlocking members between said two sides of said peripheral flange.

12. The reclosable package of claim 8 , further including a slider attached to said fastener for transitioning said fastener between an open position and a closed position.

13. The reclosable package of claim 12 , wherein said lines of weakness are above said slider, edge sections of said top sheet adjacent to said two sides of said peripheral flange being unattached to said peripheral flange allowing an entire length of said top sheet between said two sides of said peripheral flange to be folded away from said peripheral flange.

14. The reclosable package of claim 12 , wherein said lines of weakness are below said slider.

15. The reclosable package of claim 8 , wherein said lines of weakness are below said second seal.

16. The reclosable package of claim 8 , wherein one of said two sides of said peripheral flange includes a peg hole for receiving a peg to display said package in a retail setting.

17. The reclosable package of claim 8 , wherein said lines of weakness are adjacent to each other.

18. A reclosable package, comprising:

a tray having a well and a peripheral flange, said well receiving contents and said peripheral flange surrounding a perimeter of said well, said peripheral flange having a top, two sides and a bottom;

a top sheet attached to said bottom and at least a portion of each of said sides of said peripheral flange with a generally continuous first seal extending around less than the perimeter of said well, said top sheet further being attached to said top of said peripheral flange with a generally continuous second seal, said first seal being spaced from said second seal;

a fastener having first and second interlocking members, said first interlocking member being attached to said peripheral flange and said second interlocking member being attached to said top sheet, said fastener having a first end and a second end; and

a tamper-evident feature attached to said top sheet along a first line of weakness and said peripheral flange of said tray along a second line of weakness, said tamper-evident feature being removable from said package along said lines of weakness to allow access to said fastener, said lines of weakness being above said fastener, edges of said peripheral flange of said tray and said top sheet that are adjacent to said first and second ends of said fastener being unattached so that said fastener is accessible between said peripheral flange of said tray and said top sheet after said tamper-evident feature is removed.

19. The redo sable package of claim 18 , wherein each of said first and said second ends of said fastener include an unattached region, said first and second interlocking members being located between said unattached regions.

20. The reclosable package of claim 18 , wherein said fastener includes a hermetic seal adjacent to said first and second interlocking members, said hermetic seal being breakable by a consumer after said tamper-evident feature is removed from said package.
