Cap for pipe joint

Abstract

Abstract PURPOSE: To make it possible to adapt one cap to pipes of various kinds of diameters by providing a closure wall at one end of the cap and forming a circular cutting breaks. CONSTITUTION: At the left end of a cap (c) which is mounted onto the outer periphery of a rubber ring mounting convexed portion 11 of a pipe socket 1 is integrally formed a closure wall C 2 provided with a pulling member, and a circular cutting breaks 13 is formed so as to correspond to the outer diameter of the pipe insertion opening 3 through which a pipe is inserted with a rubber ring (R) interposed at the pipe socket. By so doing, if the pulling member is pulled so as to take away the central portion of the closure wall C 2 when the pipe insertion end 3 is inserted into the pipe socket 1, it becomes possible to insert the pipe and the entrance of dusts into the pipe socket 1 as well as the protection of the convexed portion 11 against any application of external impact are achieved in case the pipe is put in custody or transferred. In addition, it becomes possible to adapt the cap to the pipe insertion end 3 of various kinds of diameters by varying the diameter of the cutting breaks 13 COPYRIGHT: (C)1979,JPO&Japio
