PURPOSE:To make it difficult to be unlocked, by providing a plurality of finders to expose the symbols provided on the outer peripheral face of an outer ring every respective outer ring at a part of the peripheral face of the cover, in a captioned container including a letter-matching lock mechanism in the cover. CONSTITUTION:An inner ring 9 is inserted inside an outer ring 5 to form a lock ring 10 to rotatably fit on a cylindrical body 11. And then, it is fixed by a slip-prevention ring 12 to constitute a lock mechanism 4. A plurality of recessions 13 are provided on the inner peripheral face of the outer ring 5 to arbitrarily fit to the protrusions 14 of the inner ring 9 in order to position them so as to prohibit the relative rotation of both rings 5, 9. Simbols 6 for unlocking are arbitrarily combined and set. Moreover, a finder 7 to expose the simbols is provided at the periphery of cover 3. A plurality of grooves 19 are provided at the outer peripheral face of the cylindrical body 11 to fit spring protrusions 20 projected to the inner peripheral face of the inner ring 9, so that the simbol 6 is positioned at the center of finder 7 of the cover 3. |
