Method for measuring thickness in at least one section to inspect of a body of a hollow container, the body defining an internal volume leading to an axial opening, the method comprising the following steps: - recovery of the hollow container, the body of the recovered hollow container comprising a bottom opposite the axial opening and defining a lateral wall which extends around a longitudinal axis; - contacting the bottom and/or an internal face of the lateral wall with a contact support which fills all or part of the internal volume; - determination of a thickness respectively in N separate areas which are part of the section to inspect, by using N mobile support members (21, 22, 23; 122, 123) that are each guided by a set orientation guide positioned in one among the contact support and an exterior coverage structure covering the hollow container, knowing that the N mobile support members (21, 22, 23; 122, 123) are each slid into the guide towards: i) a first contact surface defined by a stopper (14a, 14b, 14c) intended to be in contact with the body of the hollow container in a calibration configuration without the hollow container obtained before or after the contacting step, so as to detect a first forward position of the mobile support member in question; ii) a second contact surface defined by the body of the hollow container, in an actual measurement configuration, when the body of the hollow container is again in contact with the contact support, so as to detect a second forward position of the mobile support member in question, the second forward position being representative of a thickness (e) of the body of the hollow container compared with the first forward position; - automatic control of the movement of the N mobile support members (21, 22, 23; 122, 123) by a control unit, N being an integer higher than or equal to two. - recovery of the hollow container, the body of the recovered hollow container comprising a bottom opposite the axial opening and defining a lateral wall which extends around a longitudinal axis; - contacting the bottom and/or an internal face of the lateral wall with a contact support which fills all or part of the internal volume; - determination of a thickness respectively in N separate areas which are part of the section to inspect, by using N mobile support members (21, 22, 23; 122, 123) that are each guided by a set orientation guide positioned in one among the contact support and an exterior coverage structure covering the hollow container, knowing that the N mobile support members (21, 22, 23; 122, 123) are each slid into the guide towards: i) a first contact surface defined by a stopper (14a, 14b, 14c) intended to be in contact with the body of the hollow container in a calibration configuration without the hollow container obtained before or after the contacting step, so as to detect a first forward position of the mobile support member in question; ii) a second contact surface defined by the body of the hollow container, in an actual measurement configuration, when the body of the hollow container is again in contact with the contact support, so as to detect a second forward position of the mobile support member in question, the second forward position being representative of a thickness (e) of the body of the hollow container compared with the first forward position; i) a first contact surface defined by a stopper (14a, 14b, 14c) intended to be in contact with the body of the hollow container in a calibration configuration without the hollow container obtained before or after the contacting step, so as to detect a first forward position of the mobile support member in question; ii) a second contact surface defined by the body of the hollow container, in an actual measurement configuration, when the body of the hollow container is again in contact with the contact support, so as to detect a second forward position of the mobile support member in question, the second forward position being representative of a thickness (e) of the body of the hollow container compared with the first forward position; - automatic control of the movement of the N mobile support members (21, 22, 23; 122, 123) by a control unit, N being an integer higher than or equal to two.
