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 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.

A double-walled cup and a process for production of the cup are described. The cup includes an inner cup and a tube-shaped outer sleeve, which is formed from a blank of paper material joined at its ends. The tube-shaped outer sleeve is slid axially onto a prefabricated inner sleeve and secured. The tube-shaped outer sleeve is formed from a flat blank by joining the ends of the blank before being slid on, whereby the ends of the blank are joined by an adhesive applied to a limited area of the outer sleeve. The ends of the blank are joined by a thermoplastic material in the form of an adhesive, which for example can be a hot-melt adhesive or a sealing varnish.

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.

The present embodiments describe an insulated drinking vessel with a multifunction lid. In an embodiment, the drinking vessel can be configured to receive a multifunction lid. The multifunction lid may, in one embodiment, include an opening for receiving a drinking straw. In an embodiment, the multifunction lid may additionally include an opening for drinking or sipping directly through the lid. In an embodiment, the lid may include an operable cover for covering at least one of the openings in a first position and for allowing access to the fluid through the opening in a second position. In a further embodiment, the lid may include a plurality of operable covers. A first operable cover may be configured for covering the drinking straw opening in a first position and allowing insertion of a straw in a second position. The lid may also include an operable cover for covering the sipping spout in a first position and allowing drinking directly through the spout in a second position.

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. In addition, spout adapter assembly with an adapter that releasably attaches to the canister and a plug that is received within the adapter that moves to place the spout adapter assembly into an open and a closed orientation. The plug may have a means to provide tactile feedback to a user that the spout adapter assembly is in an optimal pouring condition.

There is provided a smart beverage container for analyzing saliva. The smart beverage container comprises a body comprising a top edge with a saliva absorbing rim area configured to collect saliva of a user, a biosensor coupled to the body and configured to receive power from a power source, and a microfluidic network between the saliva absorbing rim area and the biosensor, wherein the microfluidic network comprises a plurality of channels configured to direct the collected saliva to the biosensor, wherein the biosensor is configured to analyze saliva and to provide the result of the analysis to a communication interface.

A container with a deep recessed bottom end construction is provided. The container includes an inner receptacle having a sidewall and a bottom wall defining an interior volume within the receptacle. The container further includes an outer sleeve wrapped around the inner receptacle with a lower end extending below the lower edge of the receptacle to form a deep bottom recess within a lower portion of the container. The lower end of the receptacle sidewall has a taper angle that is different from a taper angle of an upper portion of the sidewall. The lower end of the receptacle sidewall may engage or contact the inner surface of the outer sleeve. The outer sleeve may include reverse bend and/or a second bottom wall onto which a lower end of the receptacle may sit.

In a further embodiment, the lid may include a plurality of operable covers. A first operable cover may be configured for covering the drinking straw opening in a first position and allowing insertion of a straw in a second position. The lid may also include an operable cover for covering the sipping spout in a first position and allowing drinking directly through the spout in a second position.

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.
