Abstract
A system of managing the sterilisation of empty flexible pouches (1) provides applying sacrificial closures (200) to the empty pouches, loading the empty provisional closed pouches to be sterilised on a transport device (300) for the collective transportation, performing the sterilisation of the transport device (300) carrying the empty provisional closed pouches, and finally separating, in a sterile chamber, the sacrificial closures (200) from the pouches, filling and applying a tamper-proof cap (100).
Claims15
Method of preparation for the sterilisation of empty pouches, comprising the steps of:
- producing a plurality of pouches, wherein each pouch comprises a container body formed by walls made of flexible film and a spout comprising an entrance portion with an inlet and a tube with an outlet, said spout being sealingly applied to the container body so as to protrude outside of it with at least a section of the tube;
- providing said spout of the empty pouch with an irreversible sacrificial closure for the outlet of the spout, thereby obtaining empty provisional closed pouches to be sterilised;
- loading a plurality of empty provisional closed pouches to be sterilised on a transport device for collective transportation towards a steriliser.
Method of sterilisation of empty flexible pouches, comprising the steps of:
- providing a transport group comprising a plurality of transport devices, each carrying empty closed pouches to be sterilised, stacked, wherein each empty closed pouch to be sterilised comprises a container body having walls made of film, a spout sealingly applied to the container body, and a sacrificial closure sealingly and irreversibly engaged to an inlet of a tube of the spout to close it;
- performing a sterilisation of the transport group by ionising radiations.
Method for filling flexible pouches, comprising the steps of:
- providing a transport group comprising a plurality of transport devices, each carrying sterilised empty closed pouches, stacked, wherein each sterilised empty closed pouch comprises a container body having walls made of film, a spout sealingly applied to the container body and a sacrificial closure sealingly and irreversibly engaged to an inlet of a tube of the spout to close it;
- picking the sterilised empty closed pouches from the transport group and sending them in succession to a sterile chamber;
- for each sterilised empty closed pouch, making at least a portion of the tube provided with the sacrificial closure to pass through the sterile chamber;
- during said passing through the sterile chamber, opening the spout, filling the sterilised open pouch and applying a tamper-proof cap to the tube to close the pouch.
