A container includes a cup formed to include and interior region and an insulated sleeve. The insulated sleeve is coupled to an outer surface of the cup.

Methods of forming an article from a molten plastic composition comprising a polymer and a blowing agent. The methods include injecting the molten plastic composition into a mould, allowing the plastic composition to form a first solid skin adjacent to an in contact with a first cavity-forming surface of the mould and a second solid skin adjacent to and in contact with a second cavity-forming surface of the mould, and then opening the mould before the molten plastic composition between the first and second solid skins in at least one portion of the circumference of a region of the mould cavity defining an annular cross-section of the cavity has solidified.

A method for dielectrically heating foamable composition to foam and set the composition is described. In particular, radio frequency (RF) heating is used to heat the foamable composition to provide insulation in the manufacture of an article.

A container is formed to include and interior region that is configured to receive a product therein and the container is insulated.

A modular drinking container configured to receive one or more components. The modular drinking container, or mug, is configured to have at least one interchangeable component, wherein the at least one interchangeable component is configured to receive and hold one or more external accessory components. The modular drinking mug comprises a removable outer member and an inner member. The inner member is configured to receive and store a liquid therein. The outer member is configured to be positioned over the inner member and secured thereto. The outer member contains one or more locking members to provide a mechanism to secure one or more external accessories to the modular drinking container.

A hollow article for use as a beverage cup, or as a container, the hollow article having an annular sidewall and a base wall defining a central hollow cavity, a top rim of the sidewall and a bottom end of the sidewall, wherein the annular sidewall has a plastics material composed of a sandwich structure of inner and outer skins and an integral expanded cellular foam layer therebetween, wherein at least a portion of the annular sidewall has an inner surface of the sandwich structure inclined at a first acute angle to a longitudinal axis of the hollow article and an opposite outer surface of the sandwich structure inclined at a second acute angle to the longitudinal axis of the hollow article, wherein the second acute angle is greater than the first acute angle.

A multi-layer sheet includes an insulative cellular non-aromatic polymeric material, a film, and a polymeric-lamination layer. The insulative cellular non-aromatic polymeric material may be formed from a polymeric formulation comprising a base resin blend and a physical nucleating agent.
