Airtight elastic cap of ink-jet recording head, storage container, and ink-jet recording apparatus

摘要

An airtight elastic cap of an ink-jet recording head and a storage container employing the airtight elastic cap provide high airtightness between a nozzle face and the airtight cap and minimizes ink leak from the recording head even when the head is mounted or dismounted, or when a storage environment changes suddenly. The airtight elastic cap includes a body and an inside wall provided inside thereof. A portion of the wall defines a first space and another portion defines a second space positioned continuously to a center of the first space. The storage container includes a container body that houses the ink-jet recording head and the airtight elastic cap, placed within the container body, that abuts against and protects an ink emission face of the ink-jet recording head while the ink-jet recording is housed.
