Cup made of paper material having a fillable interior space formed by a shell and a base. The base via a skirt at the lower end of the interior space is fastened in a substantially liquid-tight manner to the shell, and a lower periphery of the skirt forms a footprint for the cup. The cup has an external shell composed of a planar blank of paper or paper-like material. Longitudinal edges of the blank are connected to one another in an overlap region so that the external shell forms a sleeve. The external shell, has a frustoconical shape having a first cone angle and, except for the overlap region, from the predefined spacing to the lower end is configured in a single ply. The shell, from the predefined spacing to the lower end, at least in portions tapers more heavily than in the region above the predefined spacing.

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. 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 method for making a container includes forming a first cavity of a container by shaping an inner wall so that a first surface of the inner wall defines the first cavity; forming a second cavity of the container by shaping an outer wall so that a third surface of the outer wall surrounds a second surface of the inner wall such that together the third and second surfaces define the second cavity; and connecting the inner and outer walls together. The method then includes forming a hole through the outer wall to expose the second cavity to the outside ambient environment and then applying an enamel coating, while preventing the enamel coating from being deposited in the hole. After the enamel coating is applied, the method includes heating the container to glaze the enamel coating and fix the coating to the one or more surfaces.

Apparatuses and devices for preventing heat transfer through fluids contained in a fluid container, a device of which includes an insulation system including a fluid container section for containing a liquid, a detachable insulation sleeve section for preventing heat transfer therethrough thereby maintaining temperature of the fluid contained within the fluid container, a lid section for preventing spillage of contents from the fluid container section, and optionally a straw for accessing those contents.

A multi-purpose insulating beverage container includes an outer container with an open upper end, a removable inner container configured for insertion into the outer container via the open upper end, and a cover adapted to engage the outer container and retain the inner container within the outer container. The inner container includes a plurality of annular side ledges with decreasing diameters sized to support beverage bottles or cans of different sizes.

Provided is a tumbler capable of controlling a temperature of an accommodated drink. The tumbler includes an inner cup for accommodating a drink, a frame which protects the inner cup, a heat conduction unit of which heat is exchanged with the inner cup through a lower surface and an outer circumferential surface of the inner cup to cool or heat the drink of the inner cup, and a control unit configured to control operation of the heat conduction unit. The thermal efficiency and ease of use of the tumbler are improved due to the configuration of the tumbler.

An article of drinkware is preferably made of a double walled stainless steel construction which forms a vacuum chamber. The top of the drinkware is closed with a lid, while the bottom is press fit into a base that contains a strong, permanent magnet. The magnet has a strength sufficient to form a strong, magnetic connection to any surrounding ferrous metal objects or surfaces, or to permanent magnets mounted on or in surrounding surfaces.

A system for manipulating heat transfer includes a thermal sleeve, a vessel and a lid. The thermal sleeve includes a first material and a second material. The vessel includes an outer wall disposed about an inner wall, the inner wall defining a reservoir configured to contain a liquid and the inner wall and outer wall defining a gap therebetween. The lid is configured to open to facilitate adding of the liquid to the reservoir. The thermal sleeve is configured to be positioned within the gap.

An insulating container can be configured to retain a volume of liquid, and include a canister having 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 spout adapter, the spout adapter having a spout channel extending between the internal reservoir and a spout opening, smaller than the opening of the canister. The spout opening may be sealed with a cap having a magnetic top surface, and the spout adapter may be further removably coupled to a lid that may be used as a cup into which a volume of the liquid can be poured.

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 vent hole may be formed in a bottom of a dual-walled beverage container to prevent the formation of a vacuum. The outer surface of an inner wall of a dual-walled beverage container may have an inductively couplable layer secured to the inner wall to permit heating of fluids.
