To test closed containers, e.g. with regard to residual air volume or the quality and tightness of the closures which are attached to containers, mechanical oscillations are excited in the closure, the mechanical oscillations are analyzed, measurement values are derived from this, these measurement values are compared with pre-set values for acceptable closures and a signal is produced which states whether the measurement value corresponds to a value for an acceptable closure. To increase the reliability of the test, the oscillation properties of the closure blanks (R) are also ascertained before their attachment to the containers (B) and the range of acceptable values of the closures (V) attached to the containers (B) is chosen according to the oscillation properties of the corresponding closure blank (R). The closure blanks (R) can be classified according to their oscillation properties.
Procédé de contrôle de récipients fermés selon lequel des oscillations mécaniques sont appliquées à la fermeture, des valeurs de mesure sont déduites, ces valeurs de mesure sont comparées à des valeurs données correspondant à des fermetures acceptables et un signal est produit, ledit signal indiquant si la valeur de mesure correspond à une mesure de fermeture acceptable. Pour améliorer la fiabilité du contrôle, les propriétés d'oscillation des bouchons bruts (R) sont déterminées en plus avant leur application sur les récipients (B) et la plage des valeurs acceptables des fermetures (V) appliquées sur les récipients est choisie en fonction des propriétés d'oscillation du bouchon brut (R) correspondant. Les bouchons bruts (R) peuvent être classés selon leurs propriétés d'oscillation.
