An insulated sleeve is provided to be coupled to an outer surface of a cup. The sleeve is formed from an insulative cellular non-aromatic polymeric material having an area of plastic deformation. There are no fractures in the insulative cellular non-aromatic polymeric material so that a predetermined insulative characteristic is maintained in the material.

A container for containing a cold fluid. The container includes a sidewall construct that includes an inner sidewall extending at least partially around an interior of the container, an outer sleeve attached to the inner sidewall, and a cavity defined between the inner sidewall and the outer sleeve. The container also includes a closed bottom defining a bottom of the interior of the container, and insulating features that include the cavity and a plurality of annular bands, each annular band of the plurality of annular bands includes a spacer that extends in the cavity from the inner sidewall to the outer sleeve. Adjacent bands define a respective pocket of a plurality of pockets in the cavity such that the insulating features maintain a desired temperature of the cold fluid.

An insulated container for food particulate and beverages is described. The insulated container includes a double-walled structure composed of a metal, and a glass structure arranged within a hollow interior of the double-walled structure. The glass structure includes a body and a sipping portion extending from the body. The sipping portion isolates the user's lips from contacting the double-walled structure. The glass structure may be repeatably removed for cleaning or replacement. The insulated structure includes a deformable flange that secures the glass structure to the double-walled structure. The insulated container may be vacuum-insulated.

A phase change apparatus has a generally tubular housing with an open upper and lower end and a sidewall having inner and outer surfaces with a chamber defined therein. At least one of the surfaces is convoluted, and a phase change material is disposed in the chamber. The upper end of the generally tubular housing engaged the upper end of an insulated cup. At least one passage is defined between the inner and outer surfaces of the generally tubular housing to allow the flow of liquid when the cup is tilted. The phase change material disposed in the chamber absorbs thermal energy from the liquid and then releases the thermal energy back to the liquid to maintain the temperature of the liquid.

A double-layer container comprises an inner container made of plastic and having a bottom, and a cylindrical outer layer made of paper. The outer layer is sleeved outside the inner container, a locking structure is provided between the outer layer and the inner container to snap the outer layer on an outer peripheral surface of the inner container, and the outer layer is provided with a tear tab capable of tearing and destroying the outer layer. The double-layer container reinforces the strength of the inner container and the outer layer in a radial direction through an annular groove and an annular protrusion respectively, so that the overall strength is high, and quick recycle is realized through the tear tab provided on the outer layer.

A thermobottle includes an outer mug, a sleeve, an inner mug and a cover. The sleeve includes a first abutting portion. The inner mug is sleeved within the sleeve. The first abutting portion abuts against an inner wall of the outer mug to accommodate the inner mug within the outer mug. The cover includes a second abutting portion which has the same shape and dimensions as the first abutting portion. The second abutting portion abuts against an inner wall of the inner mug or the inner wall of the outer mug. When the second abutting portion abuts against the inner wall of the outer mug, the cover seals the outer mug with the inner mug removed. When the second abutting portion abuts against the inner wall of the inner mug, the cover seals the inner mug.

An insulative beverage container includes an outer cup and an inner gap support. The outer cup includes a cup brim, a cup floor, and a cup body. The inner gap support is configured to fit within an interior space of the outer cup and includes a gap-support brim, a gap-support floor, and gap-support body.

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 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 are ceramic compositions and containers, in each case comprising a ceramic (e.g., porcelain, stoneware, porcelain, or ceramic composition having properties of both) composition to which an amount of alumina has been added to provide a ceramic composition comprising 20% to 25% (wt./wt.) alumina, preferably about 22% (wt./wt.) alumina, providing a stronger material, such that wall thicknesses (e.g., of double-walled beverage containers) can be reduced or minimized to create a lighter double-walled ceramic container. The disclosed containers have a chemical and porous structure suitable for a wide array of stoneware glazes, and display water absorption rate properties comparable to stoneware. Methods of making same are provided.
