A container for containing a fluid. The container includes a sidewall construct that includes an inner sidewall extending at least partially around an interior of the container and having an inner lower edge, and an outer sleeve attached to the inner sidewall, the outer sleeve has an outer lower edge that is spaced below the inner lower edge. The container also includes a closed bottom defining a bottom of the interior of the container.

A beverage container for hot or cold beverages, where the lid and base are connected via a glass joint. The glass joint forms a seal between the lid and base and eliminates the need for a synthetic material to form such a seal. The base has a double wall construction forming a cavity between the two walls. One or more of the surfaces facing the cavity are coated with a thermally reflective coating, which along with the glass materials, reduces heat transfer to the external surroundings. The lid is formed by a glass shell with an internal cavity, where the internal surfaces defining the cavity are optionally coated with a thermally reflective coating to further insulate the beverage container.

A beverage container assembly including a cup and a lid. The cup includes an outer wall and an inner wall. The cup may have a double truncated cone shape. The lid includes a spout for drinking a beverage held in the cup and a number of holes that allow aroma to escape from the cup. The cup includes an internal protrusion that aids in mixing the beverage.

Systems and methods for coating one or more surfaces of a drinking container with diamond-like carbon. The systems and methods may position a metallic structure of a container into electrically-conducting contact with a first electrode, and use a probe that combines an electrode and gas channel to introduce a precursor gas into an internal compartment of a container for enhanced surface coating of the metallic structure.

An insulating container can be configured to retain a volume of liquid, and include a first inner wall having a first end having an opening extending into an internal reservoir, and a second outer wall forming an outer shell. The opening can be sealed by a closure, the closure having an upper portion with a handle that has a circular curvature equal to the cylindrical portion of the closure. The closure may also have a lower portion that is joined to the upper portion by an injection molded polymer element.

A collapsible vessel for containing fluid comprises at least two interconnected tubular sections which are configured to move axially with respect to each other upon application of a substantially axial force thereto. The vessel is manipulatable between a collapsed configuration in which the sections are substantially nested to form a tube having a first length and an extended configuration in which the sections form a continuous tube having a second length which is greater than the first length. The vessel comprises locking means configured to be reversibly locked while the vessel is in the extended configuration upon the application of a rotational force to at least one section.

A container having fluid container inner body positioned within an outer body having a lower end wall with an aperture. An interior chamber is formed between sidewalls of the inner and outer bodies. A flexible and resilient stopper removably positionable in the aperture in fluid-tight sealing engagement with the end wall. A stiffening member is removably positionable within a cavity of the stopper after the stopper is positioned in the aperture to provide rigidity to the stopper to resist bending of the stopper and thereby resists unintentional dislodgement of the stopper from the aperture without first removing the stiffening member from the stopper.

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.

An insulating container may include an opening, which can be sealed by a closure. The closure may have an upper portion with a handle that has a circular curvature equal to the cylindrical portion of the closure. The closure may also have a lower portion that is joined to the upper portion by an injection molded polymer element. The closure may also be in the form of “flip” type of closure such that the lid can be selectably opened or closed by the user by rotating a flip closure into either the opened or closed position. The closure may also be a two-part lid having a lower cap that may be configured to be removably-coupled to the container and an upper cap that may be configured to be removably-coupled to the lower cap.

A paper cup of a dual structure according to one embodiment of the present invention comprises: an inner paper part having a plurality of diameter adjusting portions formed at predetermined angle intervals on one surface; a drink receiving part formed extending from one end of the inner paper part and bending formed into the inner portion of the inner paper part; and a drinking part formed at a boundary between the inner paper part and the drink receiving part and curled in a radially outward direction of the drink receiving part.
