<P>PROBLEM TO BE SOLVED: To provide cap nozzles 20 and 20a which prevent hardening by intercepting a sealing agent 11 from air in case that the sealing agent 11 is left in a cartridge body 10 and allow restart in a short time. <P>SOLUTION: Female threads 5 and 5a to be screwed with the male thread 8 of a cartridge are formed at the inside of the end X on the opening side of cap nozzles 20 and 20a, and male threads 2 and 2a to be screwed with the female threads 5 and 5a are formed at the outside of the cap nozzles 20 and 20a. Furthermore, at least a ring of roughly annular projections 4 and 4a for sealing is formed at the inside in a position close to the end X on the opening side of the cap nozzles 20 and 20a. Then, inclined parts 21 are formed at the tips of the projections 4 and 4a for sealing. <P>COPYRIGHT: (C)2012,JPO&INPIT |
