摘要： The present invention provides a measuring apparatus and method for measuring the quantity of ventilation, whereby the quantity of ventilation correlates to the heating characteristics. [The present invention is also] able to measure the quantity of ventilation of a gas permeable packing material used in heating packets in a short period of time, regardless of the type or pore diameter of the packing material. The present invention provides heating packets displaying stable heating characteristics. In the present invention, one surface of a gas permeable packing material is exposed to the atmosphere, while the opposite surface is scavenged with a carrier gas which does not include oxygen. The present invention measures the oxygen diffusing capacity, [as the diffusion of oxygen] from the atmosphere through the gas permeable packing material, by measuring the concentration of oxygen in the carrier gas after scavenging. Also, the present invention provides body, pocket, and shoe heating packets wherein the quantity of ventilation is regulated by the oxygen diffusing capacity.

摘要翻译： 本发明提供了一种用于测量通气量的测量装置和方法，由此通气量与加热特性相关。 [本发明也]能够测量在短时间内用于加热包装的气体可渗透包装材料的通风量，而不管包装材料的类型或孔径如何。 本发明提供了显示稳定的加热特性的加热包。 在本发明中，将透气性填充材料的一面暴露在大气中，同时用不含氧的载气清扫相对表面。 本发明通过测量清除后的载气中的氧浓度来测量氧扩散能力（作为氧的扩散）从大气通过透气性填充材料。 而且，本发明还提供了体积，口袋和鞋子加热包，其中通气量由氧扩散能力来调节。
