1. A treatment apparatus for treating closures for containers, the treatment apparatus comprising:
a box-like body;
a treating chamber inside the box-like body, the treating chamber configured for treating the closures;
a dispensing pipe located inside the treating chamber and configured to dispense a sterilizing substance;
a supplying circuit configured to supplying the sterilizing substance, the supplying circuit including:
a feeding line;
a main line; and
a secondary line, both the main line and the secondary line branching-off from the feeding line and the main line emerging into the dispensing pipe and the secondary line emerging inside the box-like body; and
one or more valves operatively active on the supplying circuit to establish a selective fluid communication between the feeding line and the main line or between the feeding line and the secondary line,
wherein said secondary line is designed to reproduce an overall flow resistance of the main line and of the dispensing pipe, and
the one or more valves are configured to set the treatment apparatus in one of the following configurations:
a working configuration in which the one or more valves establishes a fluid communication between the feeding line and the main line so that the dispensing pipe is supplied with the sterilizing substance and in the working configuration the one or more valves interrupt the fluid communication between the feeding line and the secondary line, and
an idle configuration in which the one or more valves establish a fluid communication between the feeding line and the secondary line so that the sterilizing substance is discharged inside an environment delimited by the box-like body and in the idle configuration the one or more valves interrupt the fluid communication between the feeding line and the main line.
