Abstract

A container with a window through which food within the container may be seen. The window may include a hole in a base material of the container, and at least one substantially clear polymeric film that is mounted to a portion of the container and obstructs (e.g., covers) the hole. Microwave energy interactive material (“MEIM”) may be mounted to the polymeric film for influencing the effect of microwave energy on the food within the container. Typically (e.g., optionally), the film extends beyond the hole, and the MEIM may be segregated to portions of the film that do not obstruct the hole, so that the MEIM does not interfere with the view through the window.

First claim

What is claimed is:

a lid comprising a central lid panel and a plurality of lid side panels foldably connected to the central, lid panel, the plurality of lid side panels comprises a first lid side panel foldably connected to the central lid panel along a first fold line, a second lid side panel foldably connected to the central lid panel along a second fold line, a third lid side panel foldably connected to the central lid panel along a third fold line, a fourth lid side panel foldably connected to the central lid panel along a fourth fold line, and a fifth lid side panel foldably connected to the central lid panel along a fifth fold line, the second lid side panel is oblique relative to the first lid side panel, the third lid side panel is oblique relative to the first lid side panel, the fourth lid side panel is perpendicular relative to the first lid side panel, and the fifth lid side panel is perpendicular relative to the first lid side panel, wherein the second lid side panel extends from the first lid side panel to the fourth lid side panel, and the third lid side panel extends from the first lid side panel to the fifth lid side panel;
a tray comprising a central tray panel and a plurality of tray side panels foldably connected to the central tray panel;
a side panel foldably connected to the central tray panel and the central lid panel, wherein the fourth lid side panel extends from the second lid side panel to the side panel, and the fifth lid side panel extends from the third lid side panel to the side panel; and
an aperture in at least a portion of each of the side panel, the central tray panel, and the central lid panel.

2. The carton of claim 1 , wherein the aperture divides the side panel into a first section and a second section.

3. The carton of claim 2 , wherein the central lid panel is foldably connected to the side panel at a sixth fold line, the central tray panel is foldably connected to the side panel at a seventh fold line, the aperture extends from the sixth fold line to the seventh fold line.

4. The carton of claim 1 , further comprising a patch attached to at least one of the side panel, the central lid panel, and the central tray panel.

5. The carton of claim 4 , wherein the patch is transparent and covers the aperture to form a viewing window in the carton.

6. The carton of claim 4 , wherein the patch comprises a polymeric film.

7. The carton of claim 6 , wherein the patch includes microwave energy interactive material mounted to at least a portion of the polymeric film.

8. The carton of claim 7 , wherein the microwave energy interactive material comprises a first portion mounted to the central lid panel and a second portion mounted to the central tray panel.

9. The carton of claim 8 , wherein the first portion and the second portion are spaced apart from the aperture.

10. The carton of claim 7 , wherein the microwave interactive material is a susceptor.

11. The carton of claim 5 , wherein the plurality of tray side panels comprises a first tray side panel foldably connected to the central tray panel along a sixth fold line, a second tray side panel foldably connected to the central tray panel along a seventh fold line, a third tray side panel foldably connected to the central tray panel along a eighth fold line, a fourth tray side panel foldably connected to the central tray panel along a ninth fold line; and a fifth tray side panel foldably connected to the central tray panel along a tenth fold line, the second tray side panel is oblique relative to the first tray side panel, the third tray side panel is oblique relative to the first tray side panel, the fourth tray side panel is perpendicular relative to the first tray side panel, and the fifth tray side panel is perpendicular relative to the first tray side panel.

12. The carton of claim 11 , wherein the first lid side panel and the first tray side panel cooperate to form an end wall of the carton, the second lid side panel and the second tray side panel cooperate to form a first sidewall of the carton, and the third lid side panel and the third tray side panel cooperate to form a second sidewall of the carton, the first sidewall and the second sidewall are angled with respect to the end wall.

13. The carton of claim 12 , wherein the end wall is a first end wall and the carton further comprises a second end wall opposite the first end wall, the second end wall comprises the side panel and at least a portion of the viewing window.

14. The carton of claim 13 , wherein the fourth lid side panel and the fourth tray side panel cooperate to form a third sidewall extending from the first sidewall to the second end wall and the fifth lid side panel and the fifth tray side panel cooperate to form a fourth sidewall extending from the second sidewall to the second end wall.

15. The carton of claim 11 , wherein the patch is in contact with at least one of the second lid side panel and the third lid side panel.
