Abstract: A food container and its method of use are disclosed. The food container includes a top panel, bottom panel and plurality of sidewalls. A movable panel is hingedly connected to one of the sidewalls, allowing a consumer to open the container. Attached to the lower edge of the movable panel is a shelf supporting a food item. A consumer can access the food item by opening the movable panel, which causes the shelf to carry the food item outside the container into a position that permits the consumer to easily manipulate it. The food item or a portion thereof can then be replaced in the container by simply closing the movable panel. The shelf may engage one or more sidewalls of the bottom panel to assist in maintaining the container in a closed position after initial opening and reclosing. The container is suitable for packaging food items that include both microwaveable and non-microwaveable ingredients. A foldable blank for manufacturing the container is also disclosed.

Abstract: The present invention is concerned with improving the delivery of a drug from a ruminal delivery device to give a consistent delivery of drug to the ruminal environment. Thus, the invention is directed to an improved ruminal drug delivery device comprising a semipermeable membrane having an exit orifice and defining a compartment, the compartment containing a swellable osmotic agent expandable driving member, a drug to be dispensed, a density element and, optionally, a partition layer between the osmotic expandable driving member and the drug formulation, wherein the improvement comprises an essentially gas-impermeable barrier means that separates the density element from the other components within the delivery device for isolating gases evolved from the density element from the other components within the delivery device. The barrier means further includes a coupling to transfer osmotic pressure to the semipermeable wall.
