  • a packing 15 is attached to the portion where the pressure pot 2 and the lid are engaged with each other, thereby enhancing a coupling force.
  • the push button 6 is pushed to release the locked opening preventing keys 10. Thereafter, the grip lever 24 is upwardly pulled, the clip plates 8 are pushed to the first direction. At this point, the opening preventing keys 10 are placed on the outer grooves of the opening preventing key grooves 12. Operator can release the sealed pressure pot and the lid. The operation will be explained in detail. Initially, the push button 6 is lightly pushed before the grip lever 24 is pulled.

By virtue of the each closure preventing groove 28, even when an external force is removed from the grip lever 24, the grip lever 24 is not downwardly moved. As the triangular sliding plate 14 is upwardly moved, the each clip plate 8 is pushed to the first direction.
