Patent ID: 11345580

Abstract:
The invention concerns a method for filling a thermoplastic container (2), comprising a mouth (2a), with a gasified liquid having a pressure (P), said method using a filling unit (1) and comprising the steps of: —Positioning the container (2) under a filling head (3) of the filling unit (1), the filling head (3) comprising a product filling valve (8); —Establishing fluid tight connection between the filling head (3) and the mouth (2a) of the container (2); —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 (2) 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 (9a, 9b); —Filling the container (2) under pressurized condition until its maximum defined volume with the gasified liquid (PL), using the product filling valve (8); —Depressurizing the container (2) using a venting valve (10); —Separating the container (2) from the filling head (3); the resulting gasified liquid in the container (2) being a mixture of the first product (FL) and of the gasified liquid (PL). The invention is also related to the associated devices.
