Abstract

Embodiments of the present invention provide a three-panel lidding device used to seal a food container. Such devices are particularly useful for covering and sealing a plastic food container, eliminating (or diminishing) the need for an outer carton and the clear film membrane that traditionally covers a food container. The lidding device may contain all brand identifiers, product messaging, ingredient list, instructions (e.g., opening and cooking) printed directly on the device. The device may also allow for venting of the food container during cooking and may then be removed for serving. The device may further provide a foot panel that allows the food product container/lidding device to sit upright, enhancing store front and freezer display options.

First claim

What is claimed is:

1. A lidding device, comprising:
a first panel comprising a lid configured to cover and directly seal contents of a food container, the first panel comprising a venting system formed by a pinch to open feature comprising two vent features formed as perforated semi-circles that are pressed in for venting during heating and pinched to open the lid when heating is complete, wherein the first panel further comprises a food-facing side having a heat sealable coating on substantially the entirety of the food-facing side;
a second panel; and
a third panel comprising a bottom panel, wherein the second panel is connected to the first panel and the third panel via perforations for removal of the panels from one another.
