Portable chiller

Abstract

Here is described a portable chiller with which an ophthalmic solution, cosmetic preparation, beverage or the like in a small container can be conveniently chilled. This portable chiller consists generally of a cylinder filled with a liquefied refrigerant gas and a chiller case. This chiller case includes a cylinderloading compartment, a cooling compartment in which the article is chilled, and a refrigerant ejection device for ejecting the refrigerant from the cylinder accommodated in the cylinder compartment into the cooling compartment. Disposed in the cooling compartment is a device adapted to keep a vent orifice of the cooling compartment to withhold gasification of the refrigerant during the period from immediately before the beginning of ejection of the refrigerant to completion of the ejection and, then, release the vent orifice to allow the refrigerant to be gasified after completion of the ejection or a porous element enshrouding the container loaded into the cooling compartment and adapted to absorb the refrigerant from the cylinder in liquid form and, then, allow the refrigerant to be gasified around the article to be chilled.
