PROBLEM TO BE SOLVED: To provide a delivery container capable of regulating the rotation direction to prevent moving-down while thinning the diameter of the whole container.SOLUTION: The delivery container comprises a delivery container body and a lid body. The delivery container body includes: an external blind cylinder; a rotation guide cylinder mounted in the external cylinder; a rotary operation cylinder rotatably mounted to the rotation guide cylinder; a middle tray body housed in the rotation operation cylinder in a manner that the middle tray body cannot rotate but can move up and down so as to be screwed with the inner periphery of the rotation guide cylinder; and a rotation regulation member mounted on the outer periphery of the rotation guide cylinder for regulating the rotation of the rotation operation cylinder. Screw projections are spirally formed on the inner periphery of the rotation guide cylinder. The rotation operation cylinder has an operation cylinder and a mounting cylinder. Downward ratchet teeth are provided on the lower end of the mounting cylinder. The middle tray body has an actuation cylinder part. Screw projection portions are spirally formed on the outer periphery of the actuation cylinder part so as to be screwed with the screw projections of the rotation guide cylinder. The rotation regulation member is provided with a fitting cylinder and a ratchet part deformable in the height direction having upward ratchet teeth on the upper end of the fitting cylinder.SELECTED DRAWING: Figure 1 |
