Abstract

A number of covers are described which are particularly well adapted to protect against freezer burn of ice cream. One such cover can protect an exposed surface of a food material, such as ice cream, where the food material is positioned in a container having a wall with an inner surface. The cover includes a rim and a membrane connected to the rim wherein the membrane is adapted to contact the exposed surface of the food material. The cover may also include at least one tab connected to the rim. The rim of the cover may further include a ridge and a curtain, and the membrane may be connected to the curtain. The cover can be positioned in the container so that the rim is biased against the inner surface of the wall thus restricting the passage of air. The membrane may be flexible and may be composed of a flexible material such as polymers, rubbers, and silicone rubbers. As the membrane makes contact with the exposed surface of the ice cream, the rim may be pulled away from its biased position against the inner surface of the wall in order to burp air away from the exposed surface of the ice cream.
