<P>PROBLEM TO BE SOLVED: To provide an easy-to-open cap which is easy to open at the stage of consumption and which is, in addition, extremely easy to close after charging contents. <P>SOLUTION: The cap comprise a cap body 4 provided with a cylindrical body 3 whose ceiling plate 2 has a rim around which an outer peripheral knurl is formed, and a ring body 6 in communication with the end part of the cylindrical body 3 of the cap body 4 through the medium of a plurality of breakable bridges 5, and thus to close a container 7 by being fitted on the mouth part 8 thereof. The arrangement of providing a slip stopper 10 for opening the cap around the outer periphery face of the cylindrical body 3 with the knurl part exposed upward of the outer periphery face of the cylindrical body of the cap body makes it possible that, after contents are charged in the container 7, the easy-to-open cap 1 is mechanically fitted onto the mouth part 8 by means of a non slip means 30 for closing the cap, and if a finger is hooked on the slip stopper for opening the cap at the time of consumption so as to turn the easy-to-open cap 1 toward the direction of opening, the force of the finger is directly transmitted so that the bridges 5 in communication with the cap body 4 and the ring body 6 can be easily broken, thus the problem is solved. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
