A cup sleeve is capable of engagement with a cup lid when being sleeved around a cup. The cup lid has a sleeve engaging member. The cup sleeve includes a sleeve body formed with a receiving space for receiving the cup, and including a bottom portion, a top portion that is opposite to the bottom portion, a surrounding wall that extends from the bottom portion to the top portion, and a lid engaging unit that is formed on the surrounding wall that is proximal to the top portion for interlocking with the sleeve engaging member of the cup lid. A cup assembly is also provided.

Various embodiments concern a handheld beverage container. The beverage container includes a vacuum chamber located radially between an inner tubular sidewall and an outer tubular sidewall and axially between an inner bottom wall and an outer bottom wall. The combined heat capacity of both of the inner tubular sidewall and the inner bottom wall can be greater than the combined heat capacity of both of the outer tubular sidewall and the outer bottom wall such that a vacuum insulated thermal reserve is formed. Heat can be exchanged between the thermal reserve and the beverage to stabilize the temperature of the beverage to counteract ambient cooling/heating of the beverage. Various embodiments concern a cap that seals with a disposable cup that is held within a container body, allowing a beverage to be contained in the disposable cup while being insulated by the container body, with or without a thermal reserve.

Disclosed herein are systems for regulating a temperature of a drink, the system comprising: a receptacle system defining a recess for receiving a drinking vessel, including: an outer receptacle, and an inner receptacle that is removably couplable to the outer receptacle, wherein a cavity is defined between the outer receptacle and the inner receptable, the receptacle system comprising a top end portion, a bottom end portion, an inner wall portion, and an outer wall portion, the top end portion defines a top opening of the recess.

A temperature-regulation receptacle system, the system comprising: a receptacle system defining a recess for receiving a stemless drinking vessel, the receptacle system including: an outer receptacle, and an inner receptacle that is removably couplable to the outer receptacle, wherein the receptacle system comprises a top end portion, a bottom end portion, an inner wall portion, and an outer wall portion, the top end portion defining an opening of the recess, wherein at least a portion of the outer wall portion is continuous about the outer receptacle, wherein the inner wall portion extends between the top end portion and the bottom end portion, the inner wall portion having at least one curved surface between the top end portion and the bottom end portion.

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.

Apparatus for controlling the temperature of a beverage container, for example, by either chilling the beverage container or maintaining the beverage container at a predetermined temperature, the apparatus having a generally cylindrical configuration with a receptacle in its upper portion and cooling components in the lower portion to establish a low center of gravity for the apparatus.

A cooling drink holder assembly includes a sleeve that has a compartment is integrated inside of the sleeve. The compartment is filled with a cooling gel to cool the beverage container when the beverage container is inserted into said sleeve. A first ring is coupled to the sleeve and a plurality of couplers is each coupled to the first ring. A second ring is included and a plurality of engagements is integrated into the second ring. Each of the couplers on the first ring releasably engages a respective one of the engagements for suspending the sleeve on an arm rest of a chair. In this way the sleeve can store the beverage container when the beverage container is extended through the arm rest of the chair.

A beverage holder with an insulating sleeve holds a beverage container and a magnetic mount to magnetically secure the insulating sleeve with the beverage container therein to a ferromagnetic support structure. The magnetic mount comprises an exterior housing located outside the insulating sleeve and on a lateral wall of the insulating sleeve. A magnet is carried by the exterior housing and located outside of the insulating sleeve. An interior backing is located on an interior of the insulating sleeve and fastened to the exterior housing through the insulating sleeve. The exterior housing and the interior backing sandwich a portion of the lateral wall of the insulating sleeve.

An insulated beverage holder device includes an insulated outer hollow cylinder, the insulated outer hollow cylinder including an open top and a bottom floor; an interior insulating hollow cylinder, the interior insulating hollow cylinder having an open top and an open bottom; and an insulating hollow liner, the insulating liner having an open top and an open bottom. The interior insulating hollow cylinder may be configured to be positioned inside the insulated outer hollow cylinder and attached to the insulated outer hollow cylinder. The insulating hollow liner may be attached to the interior insulating hollow cylinder and the insulating hollow liner to touch a first beverage container.

Disclosed herein are systems for regulating a temperature of a drink, the system comprising: a receptacle system defining a recess for receiving a drinking vessel, including: an outer receptacle, and an inner receptacle that is removably couplable to the outer receptacle, wherein a cavity is defined between the outer receptacle and the inner receptable, the receptacle system comprising a top end portion, a bottom end portion, an inner wall portion, and an outer wall portion, the top end portion defines a top opening of the recess.
