PULL-OFF CAP AND CONTAINER WITH THE SAME CAP

摘要

PURPOSE:To make it easy to cut and unseal a seal film to prevent such an accident that a pull-ring breaks at a connection from occurring by providing a reinforcing rib on a part which receives initial unsealing force to reinforce the part. CONSTITUTION:A sealing film 2 is connected via a cutting part 4 to a closing part 3 for closing a part chose to an upper end opening of a cylindrical cap 1, and a pull-ring 5 for cutting and unsealing is connected via a connection 6 to an upper face of the sealing film 2 to constitute a pull-off cap. At least a reinforcing rib 7 is provided at the closing part 3 so that the closing part 3 may not deform even if it receives relatively large unsealing force at the time of initial unsealing. Thus the unsealing force input from the pull-ring 5 can be functioned effectively to the cutting part 4 as cutting and unsealing force, thereby allowing the sealing film 2 to be easily cut and unsealed.
