Closures with a tamper evidence feature that is reshaped to connect it to the container neck are disclosed. Methods and systems for carrying out the methods, and to mold stacks for making the closures are also disclosed. The tamper evidence feature can be a band, a portion of a cylindrical skirt or a panel formed in the cylindrical skirt. The application of heat may deform the band inwardly to create a lip for engaging a flange on the container neck, or it may weld the tamper evidence feature to the flange.

Method of securing a closure on a container

Disclosed is a valve-gated hot-runner system, having: (i) a back-up sealing arrangement, including: (i) a plurality of radial gaps associated with a valve stem of a valve actuator, and (ii) a cooling system being positioned relative to the plurality of radial gaps, the cooling system being configured to freeze a drool being made to enter, under pressure, into the plurality of radial gaps, so that the drool that becomes frozen substantially reduces flow of the drool along the valve stem and toward the valve actuator.
