摘要： A recording ink container having an air vent valve including a supporting means with a first opening, a first thin film with a second opening for covering the first opening, a second thin film for covering the second opening, and sealing means between the thin films. The valve functions to release air from the container through the first opening, and to permit the introduction of air into the container through the second opening with pressures of predetermined levels.

摘要： An ink tank is provided which can apply an optimum negative pressure stably by a valve of a simple structure. To this end, the ink tank of this invention has a valve and a damper section installed in an ink flow path. The valve deforms when the negative pressure in the ink supply port is greater than a predetermined level, to temporarily open the ink flow path to introduce ink from the ink accommodation portion to the ink supply port. The damper section is installed between and communicates to the ink supply port and the valve in the ink flow path. The damper section is formed of a resilient member more easily deformed than the valve and applies a negative pressure to the interior of the ink supply port by an elastic recovery force of the resilient member.
摘要翻译：提供了可以通过简单结构的阀门稳定地施加最佳负压的墨水罐。为此，本发明的墨罐具有安装在墨流路中的阀和阻尼器部。当供墨口中的负压大于预定水平时，阀门变形，暂时打开油墨流动通道，将油墨从油墨容纳部分引入油墨供应口。阻尼器部分安装在供墨口和墨水流动通道中的阀之间并与之连通。阻尼器部分由比阀更容易变形的弹性构件形成，并且通过弹性构件的弹性恢复力将负压施加到供墨口的内部。

摘要： An ink tank capable of a stable ink supply to a print head uses a simple valve construction. In one preferred example, an ink path is closed by a lip portion of a valve rubber engaging a flange, and an angle formed by an inner surface of an opening in the lip portion and an engagement surface of the flange is an acute angle.

摘要： The invention provides a method and apparatus for manufacturing a liquid container having an enclosed space within an inner wall of the liquid container, the enclosed space filled with a plurality of porous members. The plurality of porous members include a plurality of inner porous members and a plurality of outer porous members. The method includes the step of packing the porous members into the enclosed space so that the inner porous members only contact and press against other inner porous members and/or outer porous members, and the outer porous members contact and press against the inner porous members and the inner wall of the liquid container. The method also comprises a step of compressing the porous members. The apparatus has compressing means for compressing the porous members and packing means for packing the porous members into the liquid container. The invention aims to reduce an amount of non-dischargeable liquid contained by the liquid container by packing porous members into the liquid container with a desired compression distribution. The invention also aims to allow the same kind of porous members to be suitably packed into containers that store liquids having different surface tensions, or containers having different capacities or shapes.
摘要翻译：本发明提供一种用于制造液体容器的方法和装置，该液体容器在液体容器的内壁内具有封闭空间，封闭空间填充有多个多孔构件。多个多孔构件包括多个内部多孔构件和多个外部多孔构件。该方法包括将多孔构件包封到封闭空间中的步骤，使得内部多孔构件仅接触并压靠其它内部多孔构件和/或外部多孔构件，并且外部多孔构件与内部多孔构件接触并压靠，液体容器的内壁。该方法还包括压缩多孔构件的步骤。该装置具有用于压缩多孔构件的压缩装置和用于将多孔构件包装到液体容器中的包装装置。本发明旨在通过将多孔构件以期望的压缩分布填充到液体容器中来减少由液体容器容纳的不可排出液体的量。本发明还旨在允许将相同种类的多孔构件适当地包装在容纳具有不同表面张力的液体的容器中，或具有不同容量或形状的容器中。
