Resin vessels 10 are conveyed on a air conveyor 2 while they are supported at a point below a flange 10b, and are conveyed into a drier 8 which is disposed within a sterile chamber 14 through an inlet wheel 24. The drier carries resilient grippers 11 including a pair of arms which are urged toward each other by a spring to hold a vessel sandwiched therebetween. A vessel is dried up while it is rotatively conveyed as gripped by the resilient grippers, and is then returned to the air conveyor 2 through an outlet wheel 26. A reject wheel 28 is disposed upstream of the outlet wheel and includes unlockable grippers 130 which grips the vessel at a point above the flange for taking out the vessel from the drier. A reject arm 46 is disposed downstream of the reject wheel and is movable into and from a conveying path of vessels within the drier. The reject arm causes a vessel which the reject wheel failed to grasp to be dropped onto a discharge chute 30. This allows a resin vessel 10 which has been deformed under heat as a result of a machine stop over an increased length of time to be rejected positively.
