A portable thermal insulated apparatus for cooling or heating items stored therein. The thermal insulated apparatus includes a container having a lid that removably secures to an open first end thereof and a reservoir unit that removably secures to an open second end. The container includes an inner tube and an outer tube forming an insulated double-wall sealed at both ends in which the lid and reservoir unit can be connected thereto. The reservoir unit removably receives a thermal unit that provides cooling or heating to the contents of the container when affixed thereto. The thermal unit is separable from the reservoir unit, such that the thermal units are interchangeable as needed. In some embodiments, the thermal unit is directly securable to the lid and the second end of the container is permanently sealed.

Briefly, a drinking set is provided that has a cup and a flow control disk set fully inside the cup. The flow control disk is constructed for creating a tortured flow path for any fluid flowing out of the cup. In this way, spills are substantially reduced or minimized, and the user has a stable and predictable sipping experience, even when the cup is jostled or violently moved. Fluid moving from the cup first hits a set of steeply angled entry fins, which absorb or reflect energy in the fluid. The fluid passes through a set of small entry openings, and flow to a set of exit fins, where the fluid strikes a face of the exit fins and changes direction to a set of larger exit openings. This tortured fluid path causes the drinking fluid to have a controlled flow and reduced kinetic energy as it approaches the user's mouth, multiple changes in flow direction, and provides several obstacles for absorbing kinetic energy and thus slowing the flow of the fluid.

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.

An apparatus is presented for thawing a frozen drink in a glass bottle. The apparatus includes: a housing with a bottle receiving space arranged therein and designed to accommodate a glass drinking bottle; a heating device that is arranged in the housing and has radiative heat sources that are arranged around the bottle receiving space in order to radiate heat energy onto the glass drinking bottle, and a thermal insulation and cooling device which is arranged in the housing. The thermal insulation and cooling device has a thermally insulating space which is formed between the radiative heat sources and an outer housing wall, so as to encompass the outer housing wall. An air cooling system draws air from the surroundings into the housing via an air intake and conveys the air via an air guide to an air outlet, where the air guide encompasses the thermally insulating space.

A collapsible vessel for containing fluid comprises at least two interconnected tubular sections which are configured to move axially with respect to each other upon application of a substantially axial force thereto. The vessel is manipulatable between a collapsed configuration in which the sections are substantially nested to form a tube having a first length and an extended configuration in which the sections form a continuous tube having a second length which is greater than the first length. The vessel comprises locking means configured to be reversibly locked while the vessel is in the extended configuration upon the application of a rotational force to at least one section.

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 reusable beverage container has a glass cup having a formed mouth having a smooth exterior frustoconical surface which widens in exterior diameter towards a rim of the mouth. The mouth has a height of greater than 15 mm. A lid engages the mouth. The lid has a top section and an elastomeric skirt, the top section having a drinking aperture therethrough and the skirt defining an inner frustoconical surface and an outer surface. The inner frustoconical surface conforms in shape and size to the outer frustoconical surface and the skirt thickening towards a lower edge thereof.

A container includes: a double wall vacuum insulated body including: an electroplated stainless steel inner surface or a polished stainless steel inner surface; an outer surface including a vacuum port; a mouth located at a top end of the body having a mouth diameter; and a base opening located at a bottom end of the body having a base opening diameter; a removable top cap including a top seal that seals the top opening; and a removable bottom cap including a bottom seal that seals the bottom open.
