Abstract
A capping and nitrogen dosing apparatus for containers includes a rotary capping machine which is configured to serially receive filled containers, and apply closures to respective ones of the containers. The present apparatus includes a dosing system for injecting an inert gas, typically nitrogen in liquid form, into the head space of each container to enhance the integrity and rigidity of the package, and to improve the freshness and flavor of the container's contents. Notably, the dosing system is configured to effect nitrogen injection close to or at the so-called transfer point of the capping machine, thus desirably abating nitrogen dissipation, and enhancing consistent and efficient product dosing.
