A cup includes a cup body and a cup lid. The interior of the cup body is hollow, and the top of an inner wall of the cup body is provided with a connecting piece. The cup lid is covered on the cup body. The cup lid includes an inner layer cylinder, a sandwich cylinder sleeved on the inner layer cylinder, an outer layer cylinder sleeved and clamped on an upper portion of the sandwich cylinder, a first sealing ring with an elasticity sleeved on a lower portion of the sandwich cylinder, a sealing cap detachably mounted at the bottom of the sandwich cylinder, and a cap shell covered to the outer layer cylinder and fixedly connected to the inner layer cylinder. A cylinder wall of the outer layer cylinder is provided with a connecting groove corresponding to the connecting piece.

A multi-layer sheet includes an insulative cellular non-aromatic polymeric material, a film, and a polymeric-lamination layer. The insulative cellular non-aromatic polymeric material may be formed from a polymeric formulation comprising a base resin blend and a physical nucleating agent.

An insulated container is described. The insulated container includes a double-walled structure having a closed end, an open end, and a side wall extending between the closed and open ends. The side wall and the closed end of the insulated container together form a hollow interior. A glass structure may be arranged within the hollow interior. The glass structure includes a body having an open upper end and a base end, and a sipping portion extending from the upper end. The sipping portion may include a sipping end and a shoulder end spaced apart from the sipping end. The sipping portion protrudes from the open end of the double-walled structure. A collar is positioned over the sipping portion of the glass structure thereby forming a sipping surface.

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 second outer wall can include a second end configured to support the container on a surface. The second outer wall can include a dimple, and the dimple can include a circular base and an inner portion converging to an hole extending into the second outer wall. The hole can be sealed by a resin, and the circular base can be covered by disc formed of the material. Alternatively, a cap can cover the dimple, and a weld can connect the cap to the second outer wall. The container can also include a sealed vacuum cavity forming an insulated double-wall structure between the first inner wall and the second outer wall.

A portable flashlight thermos cup with a charging function includes: a flashlight thermos cup body; a lighting mechanism on the flashlight thermos cup body; and a thermal energy conversion power generation mechanism on the flashlight thermos cup body that is electrically connected to the lighting mechanism and converts thermal energy into electrical energy; a cup body; and a plastic anti-ironing part that detaches from the cup body. The flashlight cup uses thermoelectric power generation to export the heat of hot water through metal connectors and dissipates heat through heat dissipation metal sheets to generate temperature differences. The thermoelectric power generation sheet converts thermal energy into electric energy and stores the electric energy in the battery. The battery can also be charged from outside sources and used for lighting or charging mobile power supplies. The portable flashlight thermos cup is environmentally friendly and used for outdoor emergencies.

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.

An actively heated or cooled mug has a body with a chamber that can receive and hold a beverage and a heating or cooling system disposed at least partially in a cavity below the chamber. The heating or cooling system has a heating or cooling element to actively heat or cool the chamber, power storage devices, and circuitry that controls the operation of the heating or cooling elements. A user interface is electrically connected to the circuitry and has one or more selection members actuatable a) to turn off the one or more heating or cooling element or b) to adjust a temperature setting to one of multiple temperature settings configured to control the one or more heating or cooling elements to heat or maintain the liquid at a user selected temperature.

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.

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 container assembly and a container lid are provided. The container assembly includes a container body, a lid, a sleeved portion, an annular pressing portion, and a straw. The container body has an opening portion at an upper end thereof. The lid is detachably disposed on the opening portion. The lid has an outer lid portion, an inner lid portion, and a connection portion, and the outer lid portion, the inner lid portion, and the connection portion jointly define a first heat insulation space. The connection portion has an annular abutting section, an enclosed end section, and an outer thread section arranged between the annular abutting section and the enclosed end section, and a distance between the enclosed end section and the annular abutting section is less than a distance between the enclosed end section and an inner lid top board of the inner lid portion.
