Abstract
L'INVENTION CONCERNE UNE CASSETTE DE BANDE MAGNETIQUE. DANS UNE CASSETTE CONSTITUEE PAR DEUX PARTIES 1, 2 ASSEMBLEES PAR DES VIS 3 DONT LES TETES 3A APPARAISSENT A L'EXTERIEUR, LA TOTALITE, OU L'UNE AU MOINS DES TETES DE CES VIS, EST SCELLEE 6 DE MANIERE A INTERDIRE TOUT DEVISSAGE PAR L'EXTERIEUR. L'INVENTION S'APPLIQUE NOTAMMENT A DES CASSETTES VIDEO PRETEES A DES UTILISATEURS.THE INVENTION RELATES TO A MAGNETIC TAPE CASSETTE. IN A CASSETTE CONSTITUTED BY TWO PARTS 1, 2 ASSEMBLED BY SCREWS 3 WHOSE HEADS 3A APPEAR ON THE EXTERIOR, ALL, OR AT LEAST ONE OF THE HEADS OF THESE SCREWS, IS SEALED 6 SO AS TO PROHIBIT ANY THREADING BY THE EXTERIOR. THE INVENTION APPLIES IN PARTICULAR TO VIDEO CASSETTES LENDED TO USERS.
