Abstract: A overcap is provided which covers the opening of a container. The overcap, in one form, engages an exterior of the container around the rim and along an inwardly directed flange which defines an opening of the container. The overcap snappingly engages with the container to produce an audible indication that the overcap is firmly attached to the container and that air is being expelled from inside the container. In another form, the overcap includes an invertible dome which is transformable between an upward convex position and an upward concave position.

Abstract: A plastic container for a particulate product has a footprint and includes a base and at least two and preferably four sides upstanding therefrom which generally define a container main interior volume. A top connects to the sides and includes a large opening which is closed by a lid. One side includes a pass-through handle located therein having a generally vertical segment which may define a hollow cavity in communication with the main interior volume. The opening of the top is sufficiently large to extend over a portion of the hollow cavity; or is sufficiently wide to receive about a 5? diameter cylinder therethrough, and has a ratio of a minimum span to a bottom diagonal of at least about 2:3. A shoulder between the top and sides has an angle of less than about 40°. The handle is configured and sized for easy grasping and holding.

Abstract: A plastic container for a particulate product includes a base and a surrounding wall member upstanding therefrom which generally define a container main interior volume. A top connects to the surrounding wall member and includes a large opening closed by a lid. The surrounding wall member includes a vertical side portion which is arcuate in lateral cross section and in which a pass-through handle is located having a generally vertical segment. The opening of the top is sufficiently large to extend over a portion of the hollow cavity; or is sufficiently wide to receive about a 5? diameter cylinder therethrough, and has a ratio of a minimum span to a bottom diagonal of at least about 90%. A shoulder between the top and the surrounding wall member has an angle of less than about 40°. The handle is configured and sized for easy grasping and holding.

Abstract: A blowing agent blend for making polyolefin foams comprising isopentane and at least one co-blowing agent. The co-blowing agent is either a physical co-blowing agent having a boiling point less than 28° C., or a chemical co-blowing agent, or combinations thereof. The blowing agent blend comprises less than about 99 mol % isopentane.
