<P>PROBLEM TO BE SOLVED: To provide a cap capable of preventing a wide opening part of a container for squeezing a highly viscous substance from bending deformation, and ensuring and keeping a good fitting condition. <P>SOLUTION: In the cap for the container for squeezing the highly viscous substance, a convergent nozzle 4 fitted in a screw lid-like shape from the outside on the wide opening part of a tube container 20 for squeezing filled with the highly viscous substance, and for discharging the highly viscous substance, is integrally formed under a projected condition from the central part of the upper part in the cap, and a bottom opening communicating with the space in the container under a cap screwed fitted condition to the tube container is provided at the central part of the ceiling part in the cap. In order to prevent the cap from being disconnected during squeezing, a reinforcing projected part 8 which is integrally projected toward the lower end of the cap on the ceiling part in the cap and on the periphery of the opening of the nozzle bottom, and is overlapped on the inner peripheral face of the wide opening part under a condition where the cap is screwed in the wide opening part, is installed. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
