An ice pack comprises a plastic sac with an external surface, the plastic sac forming an interior chamber, a substance within the interior chamber capable of absorbing thermal energy, and a coating, which contains one or more antimicrobial agents, on the external surface. The substance can comprise water, including polymer beads mixed with the water. The one or more antimicrobial agents can include a quaternary ammonium ion or salt thereof, such as a silane quaternary ammonium ion or salt thereof. The silane quaternary ammonium ion or salt thereof can be 3-(trimethoxysilyl)propyldimethyloctadecyl ammonium ion, 3-(trimethoxysilyl)propyldimethyloctadecyl ammonium chloride, 3-(trihydroxysilyl)propyldimethyloctadecyl ammonium ion, or 3-(trihydroxysilyl)propyldimethyloctadecyl ammonium chloride. Instead of an ice pack, the apparatus comprising the coating containing one or more antimicrobial agents can be an object that is used around injured people and/or perishable items such as heating pads, coolers, and ice pack carriers.

Two articles, such as a cooler and an article of drinkware, are magnetically coupled to each other by interaction of a magnet disposed in a patch, which is adhesively bonded to the cooler, and a ferrous metal element disposed in the article of drinkware. The patch includes shell made of plastic material, and an adhesive layer is activated by removing a peel and stick sheet. Two patches can be provided, one with a magnet and one with a ferrous metal element, in situations where both the cooler and the drinkware are without magnetic elements.

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.

Provided is a constant temperature container capable of largely improving the heat insulating property. A constant temperature container includes: a heat insulating container; a heat insulating lid configured to close the heat insulating container; a box body housed inside the heat insulating container; a box lid configured to close the box body; a phase change material provided on a bottom portion and a wall portion of the box body and the box lid; and a support member provided between the bottom portion of the box body and a bottom portion of the heat insulating container, the support member supporting the box body in such a manner that the wall portion of the box body is separated from a wall portion of the heat insulating container.

Provided is a thermostatic container that improves both the communication radio wave transmissivity and keeping cold performance of a thermostatic container. A thermostatic container includes: a vacuum heat insulating container; a vacuum heat insulating lid configured to close the vacuum heat insulating container; a box body housed inside the vacuum heat insulating container; a box lid configured to close the box body; and a phase change material provided on a bottom portion and a wall portion of the box body and the box lid. An area made of a radio wave transmissive organic substance is provided on a path leading from inside of the box body to outside of the heat insulating container.

The present invention provides a bottle type cooling pack including a case, which: has a storage space formed therein to store a refrigerant including a phase change material (PCM), the phase of which varies according to temperature; has a front surface and a rear surface, the widths of which are wider than that of a side surface thereof; and has a rectangular hexahedral shape formed through the front surface and rear surface and curved in the forward and backward directions.
