An eye mask has magnetic bodies and self-heating warm members, which are inserted in eye pads on a mask member to be placed over eyeball parts. If required, vibrators and illumination bodies may be additionally placed in the eye pads. Thus, fatigue on the eyes and surroundings thereof can be relieved by the magnetic actions of the magnetic bodies and the warming effects of the warming member, in addition to expected effects of restoring ocular functions, recovering from various ocular diseases, and so on. Furthermore, the surface of each of the eye pads is gradually curved like the inner surface of a sphere. When the eye pads are press-contact to the eyeball parts at predetermined pressures for a long time, the cornea can be warmed by the warming members so that the shape of the cornea can be changed along the shape of the eye pad, resulting in the effects of recovering from eye sight disorder such as pseudo-myopia, moderate farsightedness, or moderate astigmatism.

A self-heating or self-cooling container has a container body, a closure at one end of the body through which the contents of the container can be consumed, and a thermic module at the other end of the body having an actuator portion and an elongated reaction chamber portion that extends distally into the container body and contains a liquid reactant relatively more distally from the actuator portion than a solid reactant separated from the liquid reactant by a breakable barrier. When a user actuates the thermic module, an elongated actuator member punctures the barrier. The user can then immediately invert the container, allowing the liquid reactant to drain through the puncture into the solid reactant in the reaction chamber. The reactants mix and produce a reaction that, depending upon the reactants, either heats or cools the container contents by conduction through the thermic module wall. An advantage is that the user does not need to wait to invert the container after actuating it. Rather, the user can actuate the container, immediately invert it, wait until the contents reach the desired temperature, and consume the contents through the closure.
