Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This Application claims priority to European Application Number 12004227.0 filed Jun. 1, 2012, to Patricia A. Chee and Ronald W. Nelson entitled “Tray-Shaped Packaging,” currently pending, the entire disclosure of which is incorporated herein by reference.FIELD OF THE INVENTION

[0002] The invention relates to a tray-shaped packaging, in particular for food products, the packaging having a bottom and a circumferential margin.BACKGROUND OF THE INVENTION

[0003] Such a packaging as well as a packaging machine and method for manufacturing same are known, for example, from DE 102010034021 A1 or the related document US 2012 / 0036815 A1.

[0004] EP 0 535 451 A1 discloses a comparatively simple packaging in particular for food with a high grease content, such as bacon strips. This packaging is produced by simply placing two transparent foils on top of each other. In order to allow the bacon to become crispy during a microwave treatment, the packaging comp...

Examples

first embodiment

[0047]In contrast to the first embodiment, however, the elevations 27 are now pyramid-shaped. The pyramidal elevations 27 are arranged in a matrix pattern. Again, a step 26 is present between the central support section 24 and each of the collecting sections 25, such that each collecting section 25 entirely has a larger depth relative to the margin 22 than the support section 24.

[0048]FIG. 6 shows a top view of the tray-shaped packaging 14 of FIG. 5. FIG. 7 shows a lateral view of the packaging 14 of FIG. 5. FIG. 7 allows appreciating in particular the pyramid shape of the elevations 27.

[0049]In each of the embodiments of the packaging 14 according to FIG. 2 or 5, drainage channels 29 are provided between the elevations 27 (cf. FIGS. 3 and 6). These drainage channels 29 are configured to lead excess grease or liquid dripping from the product towards one of the collecting sections 25.

[0050]Further, FIGS. 4 and 7 show that the tray-shaped packaging 14 may rest stably on the two collec...

third embodiment

[0051]FIG. 8 shows a tray-shaped packaging 14 according to the present invention. This embodiment is similar to the embodiment shown in FIG. 5, except for lacking a step between the central support section 24 and the two lateral collection sections 25. Rather, the bottom of the support section 24 has a convex shape on its side facing the interior of the packaging 14. The elevations 27 on the support section 24 are again pyramid-shaped. However, the size of the elevations 27 is smaller in the center and larger in the periphery of the support section 24. This ensures that the peaks 30 of all elevations 27 are arranged in a common plane (P), which is represented by a dashed line. In the present embodiment, this plane is planar, but it could alternatively be curved.

[0052]FIG. 8 shows that the packaging 14 rests on a support surface 31, such as an oven tray.

[0053]FIGS. 9a to 9d show different embodiments of the elevations 27, which can be provided on the support section 24. In FIG. 9a, t...
