    • A self-heating container (10) has an internal cavity (22) for its contents and an external cavity (20) for a heating mechanism, for example, comprised of first and second chemically reactive materials which are arranged to be mixed when heating is required. A closure (30) closes the external cavity (20). When the heating mechanism is operated to mix the chemicals and cause an exothermic reaction, vapour, such as steam and hot air, is produced. The closure (30) carries an annular sealing flange (100) which engages with an annular shoulder (102) of the container. The sealing flange (100) seals the external cavity to atmosphere and preserves the reactivity of the chemicals therein. However, the sealing flange (100) is moved away from the shoulder (102) when the generation of the vapour increases the pressure in the external cavity (20) whereby the vapour is vented to atmosphere.
    • 自加热容器(10)具有用于其内容物的内部空腔(22)和用于加热机构的外部空腔(20),所述外部空腔(20)例如由第一和第二化学反应性材料构成,所述第一和第二化学反应性材料被布置为当加热时被混合 需要。 封闭件(30)封闭外部空腔(20)。 当加热机构操作以混合化学品并引起放热反应时,产生诸如蒸汽和热空气的蒸汽。 封闭件(30)承载与容器的环形肩部(102)接合的环形密封凸缘(100)。 密封凸缘(100)将外部空腔密封到大气中并保持其中的化学品的反应性。 然而,当蒸汽的产生增加了外部空腔(20)中的压力时,密封凸缘(100)离开肩部(102),从而蒸气排放到大气中。

    • A cold pack 10 made in accordance with the principles of the present invention includes a container 18. Disposed within the container 18 is a first endotherm-producing chemical 15. Also disposed within the container 18 is a solvent packet 13 and a chemical packet 11. Second endotherm-producing chemical 43 is disposed in the chemical packet 11. First endotherm-producing chemical 15, the solvent packet 13 and the chemical packet 11 are collectively components of the cold pack. Preferably the container 18 is sealed so as to surround and encase the components of the cold pack 10. The first endotherm-producing chemical 15 and the second endotherm-producing chemical 43 are selected to be different. Both the first endotherm-producing chemical 15 and the second endotherm-producing chemical 43 may be selected from among those compounds with a positive enthalpy of solution (&Dgr;sol/H°, kJ/mol) and which produce a reduced temperature of solution that is greater than 10° F. and provide the cold pack 10 with an extended life.

    • 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.
    • 自加热或自冷却容器具有容器主体,在主体的一端处的容器的内容物可以被消耗的封闭件,并且在本体的另一端的热模块具有致动器部分和 延伸的反应室部分,其远离地延伸到容器主体中并且包含比致动器部分更远离的液体反应物,而不是通过可破坏的屏障与液体反应物分离的固体反应物。 当用户致动热模块时,细长的致动器构件穿透屏障。 用户可以立即反转容器,允许液体反应物通过穿刺排入反应室中的固体反应物。 反应物混合并产生反应,根据反应物,通过传导通过热模块壁来加热或冷却容器内容物。 一个优点是用户在启动后不需要等待反转容器。 相反,用户可以致动容器,立即反转,等待内容物达到所需温度,并通过封闭件消耗内容物。
