Patent number: 11392076Abstract: A recovery container includes a container body, a discharge port, an opening/closing part, a guide part, and an inclination suppressing part. The container body with a recovery path is removably attached to an attachment target. The powder transported through the recovery path is discharged to outside through the discharge port. The opening/closing part closes the discharge port. In an attached state in which the container body is attached to the attachment target, the opening/closing part is push-opened by a periphery of a recovery port provided in the attachment target. The guide part extends in the attachment direction of the container body to guide movement of the opening/closing part. The inclination suppressing part comes into contact with a portion of the attachment target before the periphery of the recovery port comes into contact with the opening/closing part to suppress inclination of the container body.Type: GrantFiled: August 9, 2020Date of Patent: July 19, 2022Assignee: FUJIFILM Business Innovation Corp.Inventors: Lei Yuan, Satoshi Hashimoto, Yusuke Sakai, Hirohisa Hoshino
