Problems solved by technology

[0004] The recording head in the inkjet recording device uses heat and vibration to control the ejection of ink droplets. If the ink cartridge is cut off or cannot supply ink, the ink ejection action will fail, and failure will occur.

Abstract

To provide a liquid storage container which can prevent a failure that air bubbles are sucked into a liquid guide path even when the amount of liquid remaining in the liquid storage chamber is reduced and which can considerably reduce the amount of liquid discarded without being used. [Solving Means] A liquid storage container (1) includes liquid storage chambers (370, 430) from which liquid is guided to a liquid-supplying unit (50) through a liquid guide path and a liquid remaining-amount sensor (31) for detecting the presence / absence of the liquid on the basis of variation in residual vibration that occurs when air bubbles enter the liquid guide path. The liquid storage chambers (370, 430) have concavities (374, 434) in the bottom walls thereof. Liquid outlets (371, 432) that communicate with the liquid guide path are formed at the bottom of the concavities (374, 434), respectively. Therefore, air layers in the liquid storage chambers (370, 430) are prevented from coming into contact with the liquid outlets (371, 432), respectively, before the remaining liquid does.

Description

technical field [0001] The present invention relates to a liquid container for supplying a liquid to a liquid consuming device, the liquid being stored in a container body detachably attached to the liquid consuming device. Background technique [0002] Examples of the above-mentioned liquid container and liquid consuming device include an ink cartridge storing ink, and an ink jet recording device in which the ink cartridge is replaceably mounted. [0003] The composition of the above-mentioned ink cartridge generally includes: an ink containing chamber, which is filled with ink in a container body detachably mounted on an ink cartridge mounting portion of an inkjet recording apparatus; and an ink supply portion, which is used to store The liquid in the inkjet recording device is supplied to the inkjet recording device; the ink guide passage is connected to the ink storage chamber and the ink supply hole; and the atmosphere communication passage is introduced from the outsid...
