Abstract
A clean-keeping type film-sealing aluminum tube comprises a tube body and a cap cover. A protective lining sleeve is fixedly sleeved outside a tube opening of the tube body, the protective lining sleeve is in a shape of a cylinder with two open ends, threads are formed at the outer periphery of the protective lining sleeve, the cap cover is sleeved outside the protective lining sleeve, and the cap cover is connected with the protective lining sleeve through the threads. A tooth-shaped structure is arranged in an inner peripheral wall of the protective lining sleeve in the peripheral direction. The threads at the outer periphery of the protective lining sleeve are saw-tooth threads, axial sections of the saw-tooth threads are saw-tooth-shaped, and the saw-tooth threads slant to the lower end of the protective lining sleeve. The hardness of the cap cover is higher than or lower than that of the protective lining sleeve. An annular boss at the position of the tube opening is in sealing connection with a clamping groove of the protective lining sleeve, the protective lining sleeve is in sealing connection with the cap cover through the threads, the tube body and the protective lining sleeve are connected through the tooth-shaped structure in the peripheral direction, and sliding can be avoided. The hardness of the cap cover is different from that of the protective lining sleeve, so that certain torque force of the cap cover can be achieved, and the cap cover cannot drop easily.
Description
Technical field:
