Method for filling container with a gasified liquid and associated devices

Abstract

The invention concerns a method for filling a thermoplastic container (), comprising a mouth (), with a gasified liquid having a pressure (P), said method using a filling unit () and comprising the steps of: —Positioning the container () under a filling head () of the filling unit (), the filling head () comprising a product filling valve (); —Establishing fluid tight connection between the filling head () and the mouth () of the container (); —Delivering a first volume of a first product (FL) in the container, said first volume being less than 10% of the maximum defined volume of the container; —Pressurizing the container () with a pressurized gas (G) at a pressure similar to the pressure (P) of the gasified liquid to be filled, using at least one pressurization valve (); —Filling the container () under pressurized condition until its maximum defined volume with the gasified liquid (PL), using the product filling valve (); —Depressurizing the container () using a venting valve (); —Separating the container () from the filling head (); the resulting gasified liquid in the container () being a mixture of the first product (FL) and of the gasified liquid (PL). The invention is also related to the associated devices.
