<p>PURPOSE:To process the hollow part of the flexible tube in an installed state and to prevent it from falling off by forming small the outside diameter of the installing part extending from the closed part side of a cap body to the opening part side, and forming a fall-off stopping part in the installing part of the opening part side of the cap body. CONSTITUTION:When a cap 1 is installed in a medical treatment-flexible tube 12, the diameter of the tip part of the tube 12 enlarges in accordance with a tapered part 10. In that case, a projecting wire for connecting a projecting portion 3 of the inside surface side wall and a projecting portion 7 of the installing part 5 is formed, therefore, the tip opening part of the tube 12 is not closed up by a bottom part of a cap body 2. Also, the tube 12 adheres closely to a flat part 11 by a face contact, and pressed to the outside by an elastic projecting piece 9, therefore, it can be prevented that the cap 1 falls off. In the case of executing a sterilization processing, ethylene oxide gas flows into a hollow part of the tube 12 through recessed grooves 4, 8 which function as communicating parts from an opening part of the cap body 2, therefore, in a state that the cap 1 is installed, the flexible tube 12 can be sterilized.</p> |
