Abstract
According to the process, each returning bottle is examined for the presence of a predetermined level of fatigue damage. If this level has been reached, the bottle concerned is marked with a mark enabling further trips of the bottle to be counted. When the count has reached a predetermined value, that is when the bottle has undergone the predetermined number of fillings, the bottle is removed upon its next return. It has been found that the life of the bottle can be anticipated with high accuracy in this way, thus enabling bottles to be withdrawn from circulation before failure occurs.
