Abstract: Foldable container including a base having a first base portion and an opposing second base portion. The base has a base surface free of hinge lines between the first base portion and the second base portion. A sidewall surrounds at least a portion of the base and extends generally upward from the base with a non-uniform height to define a compartment. A rim having a first rim portion and an opposing second rim portion is disposed proximate the top edge of the sidewall. At least one transition region is formed in the sidewall to allow the first base portion to pivot between an open position and a closed position. When in the open position, the container defines a plate. When in the closed position, the first base portion defines at least a portion of a cover relative to the second base portion. A packaged product is also provided, including a foldable container and a cover member removably attached to the rim of the foldable container in the open position to contain a product therein.

Abstract: A disposable cup lid including a body and a mounting portion extending around the periphery of the body. The body defines a suitably shaped clearance area to accommodate a person's nose when drinking the contents of a cup having the lid positioned thereon. The body also defines an enhanced drinking area which is suitably configured to provide a person with a drinking experience more similar to the drinking experience of drinking from an uncovered cup or glass. In one embodiment, the body includes a raised portion which defines a lip engaging front wall and an enhanced drinking area. The enhanced drinking area includes a closure member having an upwardly extending gripping member and a drink-through opening initially covered by the closure member, wherein the drink-through opening is positioned substantially adjacent to the lip engaging front wall. The closure member is movable about a hinge from an initial closed position to an open position.

Abstract: A blowing agent blend for making thermoplastic polymer foams includes methyl formate. The blowing agent blend can further comprise at least one co-blowing agent. The co-blowing agent is either a physical co-blowing agent (e.g. an inorganic agent, a hydrocarbon, a halogenated hydrocarbon, a hydrocarbon with polar, functional group(s), water or any combination thereof), or a chemical co-blowing agent, or combinations thereof. The thermoplastic polymer foam can be an alkenyl aromatic polymer foam, e.g. a polystyrene foam. The blowing agent blend includes methyl formate and one or more co-blowing agents. The methyl formate-based blowing agent blends produce dimensionally stable foams that have improved resistance to flame spread. A process for the preparation of such foams is also provided.

Abstract: Disposable lid comprises a thermoformed sheet in the shape of a lid for a hot beverage container. The sheet comprises a polymer composite of a polyolefin and at least one mineral filler. The sheet has a thickness less than about 0.035 inches and a heat deflection temperature at least comparable to that of high impact polystyrene.
Abstract: A molding apparatus can include a primary mold, a stripper, and a swinging member. The swinging member can comprise a molding surface defining an undercut portion of a molded item. The swinging member can directly contact or attached to the stripper and the primary mold. To facilitate removal of a molded item, the swinging member can withdraw through a hole in the primary mold as a direct result of a motion of the stripper to pull the molded item off the primary mold. The molded item can then be easily removed.
