Resealable bottles for beverages. A bottle may include a main body with an opening for receiving contents and a reservoir for storing contents, a lid, and a bottom, which is interchangeable with an accessory for changing a characteristic of the contents. The lid may close the bottle and/or facilitate consumption of its contents. The bottle may support one or more indicators, such as LEDs, including a safety indicator that is configured to activate when the safety system is active and the resealable bottle enters an unsafe state. The accessory may provide, for example, heating and/or cooling.

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.

Provided are multiply-insulated articles, comprising at least first and second containers disposed together such that the interior volume of the first container is sealed against the environment exterior to the article.

Disclosed is a vacuum compartment structure for a cup lid and a manufacturing method thereof. The vacuum compartment structure for a cup lid includes a stainless steel cylinder body and a compartment upper cover. The compartment upper cover is covered on the cylinder body and has an inwardly recessed shape, and the compartment upper cover and the cylinder body are fixedly connected and sealed by laser welding. The compartment upper cover and the cylinder body form a vacuum chamber, which has a getter therein. The compartment upper cover is arranged with a plastic upper cover layer, an outer surface of the cylinder body is wrapped with a plastic lower cover layer, and the plastic upper cover layer is combined with the plastic lower cover layer to fasten and wrap the compartment upper cover and the cylinder 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 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.

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.
