Abstract
A recording head is proposed having an ejection outlet for ejecting recording ink, and a container for the recording ink having an air vent. A single sealing member seals both the ejection outlet and the air vent so that when this sealing member is removed, both the ejection outlet and the air vent are unsealed.
