Abstract

A package includes a lid with a peel initiator portion and a remaining portion. The package further includes a tray. The tray includes a rigid component and a liner component including a liner-flange portion. The package further includes an adhered area which includes a seal between the peel initiator portion and the liner component. A lid-flange portion includes the peel initiator portion and the remaining portion. The adhered area includes the lid-flange portion of the peel initiator portion and the liner-flange portion. Further, the adhered area includes 90 percent or less of an area of the peel initiator portion.

First claim

The invention claimed is:

1. A package comprising:
a lid comprising a peel initiator portion and a remaining portion adjoined by a line of weakness;
a tray comprising a rigid component and a liner component comprising a liner-flange portion; and
an adhered area comprising a seal between the peel initiator portion and the liner component;
wherein the adhered area comprises the peel initiator portion and the liner-flange portion, wherein the adhered area comprises 90 percent or less of an area of the peel initiator portion, and wherein the peel initiator portion facilitates removal of the liner component from the rigid component.

2. The package of claim 1 , wherein the liner-flange portion comprises an edge comprising a non-linear edge portion and the adhered area comprises the non-linear edge portion.

3. The package of claim 1 , further comprising a liner bond strength between the rigid component and the liner component and a bond strength of the adhered area, and wherein the bond strength of the adhered area is greater than the liner bond strength.

4. The package of claim 1 , wherein the peel initiator portion further comprises an unadhered area adjoined to the adhered area.

5. The package of claim 1 , wherein the rigid component comprises at least one of a semi-rigid polymeric material, a rigid polymeric material, a fiber-based component and a formable paper.

6. The package of claim 1 , wherein the rigid component comprises amorphous polyethylene terephthalate (APET).

7. The package of claim 1 , wherein the liner component comprises at least one barrier layer.

8. The package of claim 1 , wherein a material of the rigid component and a material of the liner component have different recycling profiles.

9. A method of using the package of claim 1 , the method comprising the steps of:
providing the package; and
grasping the peel initiator portion of the lid to peelably separate the liner component from the rigid component.

10. A package comprising:
a lid comprising a peel initiator portion is adjoined to a remaining portion along a line of weakness, and a lid edge;
a tray comprising a rigid component and a liner component comprising a liner edge, the liner edge comprising a non-linear edge portion; and
an adhered area comprising a seal between the peel initiator portion and the liner component;
wherein the lid edge comprises the peel initiator portion and the remaining portion, wherein the adhered area comprises the lid edge of the peel initiator portion and the non-linear edge portion of the liner edge, wherein the adhered area comprises 90 percent or less of the peel initiator portion, and wherein the peel initiator portion facilitates removal of the liner component from the rigid component.

11. The package of claim 10 , further comprising a liner bond strength between the rigid component and the liner component and a bond strength of the adhered area, and wherein the bond strength of the adhered area is greater than the liner bond strength.

12. The package of claim 10 , wherein the peel initiator further comprises an unadhered area adjoined to the adhered area.

13. A packaged product comprising:
a lid comprising a peel initiator portion and a remaining portion adjoined by a line of weakness;
a tray comprising a rigid component and a liner component comprising a liner-flange portion;
an adhered area comprising a seal between the peel initiator portion and the liner component; and
a product disposed within the tray;
wherein the adhered area comprises the lid flange portion of the peel initiator portion and the liner-flange portion, wherein the adhered area comprises 90 percent or less of an area of the peel initiator portion, and wherein the peel initiator portion facilitates removal of the liner component from the rigid component.

14. The packaged product of claim 13 , wherein the lid comprises an edge comprising a non-linear edge portion and the adhered area comprises the non-linear edge portion.

15. The packaged product of claim 13 , further comprising a liner bond strength between the rigid component and the liner component and a bond strength of the adhered area, and wherein the bond strength of the adhered area is greater than the liner bond strength.

16. The packaged product of claim 13 , wherein the peel initiator portion further comprises an unadhered area adjoined to the adhered area.

17. The packaged product of claim 13 , wherein a material of the rigid component and a material of the liner component have different recycling profiles.
