    • A container for containing liquid to be ejected. The container includes a negative pressure producing member accommodating chamber for accommodating a negative pressure producing member. The negative pressure producing member accommodating chamber is provided with an air vent for fluid communication with ambience and a liquid supply portion for supplying the liquid to a liquid ejecting head having ejection outlets. The container also includes a liquid containing chamber which is substantially hermetically sealed except for a fluid communication path through which the liquid containing chamber is in fluid communication with the negative pressure producing member accommodating chamber. A partition is provided for separating the negative pressure producing member accommodating chamber and the liquid containing chamber. The partition is provided with an ambience introduction path for introducing the ambience into the liquid containing chamber from the negative pressure producing member accommodating chamber. The ambience introduction path forms a capillary force generating portion. The capillary force which is produced by the capillary force generating portion satisfies a relationship between that capillary force and potential head differences, head losses, and other capillary forces in the container.
    • 用于容纳待喷射液体的容器。 容器包括用于容纳负压产生构件的负压产生构件容纳室。 负压产生构件容纳室设置有用于与环境流体连通的通气口和用于将液体供应到具有喷射出口的液体喷射头的液体供应部分。 容器还包括基本上气密密封的液体容纳室,除了液体容纳室与负压产生构件容纳室流体连通的流体连通路径。 设置有用于分离负压产生构件容纳室和液体容纳室的隔板。 隔壁设置有用于从负压产生构件容纳室将气氛引入液体容纳室的环境引导路径。 环境引导路径形成毛细管力产生部分。 由毛细管力产生部产生的毛细管力满足该毛细管力与潜在头部差异,头部损失以及容器中的其他毛细作用力之间的关系。
