An article includes walls defining an insulating space therebetween and a vent forming an exit for gas molecules during evacuation of the space. A distance separating the walls is variable in a portion adjacent the vent such that gas molecules are directed towards the vent imparting a greater probability of molecule egress than ingress such that deeper vacuum is developed without requiring getter material. The variable-distance portion may be formed by converging walls. Alternatively, a portion of one of the walls may be formed such that a normal line at any location within that portion is directed substantially towards a vent opening in the other wall.

Provided are a smart bottle and a method for controlling the smart bottle. A smart bottle comprises a bottle for containing liquid; a base formed to be combined to one side of the bottle; a first sensor installed in the bottle or the base, and configured to obtain level information of liquid contained in the bottle; a third sensor configured to obtain inclination information of the bottle; a heater configured to heat the liquid contained in the bottle; a controller configured to control operation of the heater based on the temperature information, determine a feeding start and a feeding end based on the inclination information, and modify the level information based on the inclination information; a communication unit configured to transmit the inclination information and the level information to an external device; and a battery configured to supply power to the first sensor and the base.

A travel mug that maintains its liquid contents at temperature while cooling portions of the beverage on demand to a safe and comfortable drinking temperature. In embodiments, a passive cooling system is integrated into the travel mug for drawing heat from the beverage as the user consumes it. In embodiments, a brewing system may be integrated to brew beverage matter into a drinkable beverage. In embodiments, a heating element may be provided to raise water to brewing temperature or to further heat the liquid in the container.

A food and beverage warming device. The warming device comprises a housing that preferably resembles a thermos or a pot. The housing includes an interior volume defining a heating chamber in which food can be placed for heating. The housing includes a heating element operated via a control switch for electrically heating the food within the heating chamber. The control switch allows the user to adjust the temperature of the heating element. The housing further includes a lid having a hollow interior volume so that the lid can be used as a bowl or cup. Further, the housing may removably enclose a serving tray on which food can be heated and served. The warming device may include its own power source or may be powered via an electrical connection to a wall outlet or other conventional power source.
