PROBLEM TO BE SOLVED: To provide a closed-type kneader which improves airtightness when a loading port for a material to be kneaded is closed. SOLUTION: This closed-type kneader comprises: a kneading chamber 14 for kneading the material G to be kneaded, a loading port 26 for loading the material G to be kneaded into the kneading chamber 14, a door plate 30 for opening/closing the loading port 26, and an elastic tube 38 which is fitted to the circumferential surface of the door plate 30 and pressed to the inner circumferential surface of the loading port 26 as expanded in such a state that the loading port 26 is closed by the door plate 30 and as a result, seals a clearance between the door plate 30 and the loading port 26. Thus, in the close-type kneader, the airtightness is improved when the loading port 26 for the material G to be kneaded is closed. COPYRIGHT: (C)2011,JPO&INPIT
