En résultat, le corps de capuchon (2) et la bande d'évidence d'effraction (3) sont séparés, et des parties (10a) restant après que la fente (10) a été formée dans les nervures internes (12) servent de parties de liaison (11). Par conséquent, des ponts (8) sont formés sur un capuchon de résine (1). La dimension périphérique (a) des parties de liaison (11) des ponts (8) est établie de façon à être dans la plage de 0,65 à 1,10 mm, et la profondeur des fentes (10) est accrue de façon à réduire la dimension (b) des parties de liaison (11) dans la direction radiale. En résultat de la configuration, la résistance d'une partie spécifique de chacun des ponts (8) est maintenue, et les ponts (8) peuvent être rompus rapidement.
