Abstract
A flowback method for a product contained in the distribution circuit of a filling machine. The distribution circuit ( ) creates an upstream/downstream link between a storage tank for said product and a filling tube ( ) that is placed opposite the opening of a receptacle ( ) that is to be filled. The method includes a step whereby a closed area around the filling tube ( ) is defined by a sealed housing ( ). The method further includes a step whereby a circulating liquid is injected into the above-mentioned area under pressure. The liquid passes through an auxiliary port ( ), whereupon the product contained in the distribution method ( ) flows back in the direction of the storage tank.
