Abstract: A container handling machine including at least one operative unit comprising support means to support a shaped container, and a plunger selectively moved along a given axis to deform a base of the container from a first swollen configuration to a second configuration, in which the base is in part retracted inwardly of the container with respect to the first configuration so as to form a recess delimited by a boundary surface defining an internal volume of the container smaller than that in the first configuration. The plunger is provided with a shaped head interacting with the container base and comprising: first engaging means and an interacting surface.

Abstract: A labelling machine for applying labels on respective containers is disclosed. The labelling machine is provided with at least one operative unit, adapted to receive a relative container to be labelled and having a support element for supporting a base portion of the container, with a conveyor device for transferring the operative unit from a feeding station of the containers to an outlet station, and with feeding means for providing at least one label to be applied on the container borne by the operative unit The operative unit also comprises an actuator element borne by the conveyor device on the opposite side of the support element with respect to the receiving position of the container.
