Machine (18, 19) for processing containers (1) including a base (7) having a high standing ring (8) and a central invertible diaphragm (9), the machine (18, 19) including: a container supporting frame (20) including a hollow support ring (21) for engaging a container base (7),a pusher (26) movable w
Machine (18, 19) for processing containers (1) including a base (7) having a high standing ring (8) and a central invertible diaphragm (9), the machine (18, 19) including: a container supporting frame (20) including a hollow support ring (21) for engaging a container base (7),a pusher (26) movable with respect of the container supporting frame (20), capable of coming into abutment with the container base (7) through the supporting frame (20),an actuator (28) for slidingly moving the pusher (26) frontwards towards the container base (7) through the supporting frame (20), and backwards,a strain gauge (29) coupled to the actuator (28) for gauging a strain applied by the actuator (28) to the pusher (26),a control unit (30) including a processor (32) connected to the strain gauge (29) and programmed for comparing a gauged strain value to a memorized strain reference value.

1. Method for processing a container (1) provided with: a sidewall (6),a neck (2) defining an opening (3),and a base (7) including a high standing ring (8) and a central invertible diaphragm (9), said diaphragm (9) being deformable with respect of the sidewall (5) between a lower position wherein sa
1. Method for processing a container (1) provided with: a sidewall (6),a neck (2) defining an opening (3),and a base (7) including a high standing ring (8) and a central invertible diaphragm (9), said diaphragm (9) being deformable with respect of the sidewall (5) between a lower position wherein said diaphragm (9) projects outwardly with respect of the container (1) and an upper position wherein said diaphragm (9) projects inwardly with respect of the container (1), said method including the steps of: filling the container (1) through said opening (3) with a pourable product (16), the diaphragm (9) being in its lower position;closing the container (1) at its neck (2) with a cap (17);inverting the diaphragm (9) from its lower position to its upper position by means of a movable pusher (26); wherein said method further includes the steps of: gauging a strain applied to the movable pusher (26) while inverting the diaphragm (9);memorizing a gauge point (Mi) based on the gauged strain value (PMi);comparing the gauged point (Mi) to a memorized predetermined reference point (M0);periodically gauging the strain applied to the movable pusher (26) along the diaphragm inversion;memorizing the such gauged strain values; anddetecting, among the memorized gauged points, a gauged critical point (Mi);wherein comparing the gauged critical point (Mi) includes comparing a gauged critical strain value (PMi) to a predetermined critical reference strain value (PM0). 2. Method according to claim 1, wherein gauging the strain applied to the movable pusher (15) is achieved with a period shorter than 10 ms. 3. Method according to claim 1, wherein comparing the critical gauged point (Mi) includes comparing a gauged critical instant (ti) to a predetermined reference critical instant (t0). 4. Method according to claim 1, further including the step of generating a warning signal if the gauged strain value is declared different from the reference strain value. 5. Method according to claim 1, further including the step of ejecting the container (1) if the gauged strain value is declared different from the reference strain value. 6. Method according to claim 1, wherein the pusher (26) is mounted onto a movable rod (35) of a hydraulic or pneumatic cylinder (28), wherein the rod (35) is fixed to a piston (34) which defines within the cylinder (28) a front chamber (38) around the rod (35) and a back chamber (39) opposite to the rod (35), wherein said back chamber (39) is in fluidic connection with a source (42) of fluid under pressure, wherein the step of determining the effective strain applied to the pusher (26) comprises measuring a fluidic pressure within the back chamber (39). 7. Method according to claim 1, including a step of filling the container (1) with a hot pourable product (16), and further including, between the steps of closing the container (1) and inverting the diaphragm (9), a step of cooling the container (1). 8. Method according to claim 1, further including a step of gauging a displacement of the pusher (26). 9. Method for processing a container (1) provided with: a sidewall (6),a neck (2) defining an opening (3),and a base (7) including a high standing ring (8) and a central invertible diaphragm (9), said diaphragm (9) being deformable with respect of the sidewall (5) between a lower position wherein said diaphragm (9) projects outwardly with respect of the container (1) and an upper position wherein said diaphragm (9) projects inwardly with respect of the container (1), said method including the steps of: filling the container (1) through said opening (3) with a pourable product (16), the diaphragm (9) being in its lower position;closing the container (1) at its neck (2) with a cap (17);inverting the diaphragm (9) from its lower position to its upper position by means of a movable pusher (26); wherein said method further includes the steps of: gauging a strain applied to the movable pusher (26) while inverting the diaphragm (9);memorizing a gauge point (Mi) based on the gauged strain value (PMi);comparing the gauged point (Mi) to a memorized predetermined reference point (M0);periodically gauging the strain applied to the movable pusher (26) along the diaphragm inversion;memorizing the such gauged strain values; anddetecting, among the memorized gauged points, a gauged critical point (Mi);wherein comparing the critical gauged point (Mi) includes comparing a gauged critical instant (ti) to a predetermined reference critical instant (t0). 10. Method according to claim 9, wherein gauging the strain applied to the movable pusher (15) is achieved with a period shorter than 10 ms. 11. Method according to claim 9, further comprising the step of generating a warning signal if the gauged strain value is declared different from the reference strain value. 12. Method according to claim 9, further comprising the step of ejecting the container (1) if the gauged strain value is declared different from the reference strain value. 13. Method according to claim 9, wherein the pusher (26) is mounted onto a movable rod (35) of a hydraulic or pneumatic cylinder (28), wherein the rod (35) is fixed to a piston (34) which defines within the cylinder (28) a front chamber (38) around the rod (35) and a back chamber (39) opposite to the rod (35), wherein said back chamber (39) is in fluidic connection with a source (42) of fluid under pressure, wherein the step of determining the effective strain applied to the pusher (26) comprises measuring a fluidic pressure within the back chamber (39). 14. Method according to claim 9, comprising a step of filling the container (1) with a hot pourable product (16), and further including, between the steps of closing the container (1) and inverting the diaphragm (9), a step of cooling the container (1). 15. Method according to claim 9, further comprising a step of gauging a displacement of the pusher (26).
