Claims

[Claims for Utility Model Registration] (1) A tube-end protection cap made of synthetic resin that fits into the tube end, and the peripheral wall of the tube-end protection cap has a dot on the side that comes into contact with the tube peripheral surface. A tube end protection cap characterized in that a plurality of linear protrusions extending in the axial direction of the tube are formed, and a ventilation groove extending in the axial direction of the tube is further formed on the side that comes into contact with the circumferential surface of the tube. . (2) A tube-end protection cap made of a pot-shaped synthetic resin that is fitted into the socket-side tube end with a ring-shaped packing arranged on the inner periphery, and the outer surface of the peripheral wall of the tube-end protection cap has the claim ( In addition to forming the protrusions and ventilation grooves described in 1), a taper whose diameter gradually decreases toward the bottom wall is formed on the outer surface of the peripheral wall, and the tapered portion abuts and is locked to the packing. A tube end protection cap characterized in that it is configured so as to
