Abstract
A method and kit for draining a flexible container holding a product having a viscosity of between 10 Pa·s and 200 000 Pa·s. The method includes using a flexible container (3); optionally, moving the container (3) to be drained to a drainage site; ensuring the viscous product (2) can flow from container (3) through at least one outlet (9); exerting a pressure on at least one defined area of container (3) using a pressurizing device which preferably includes at least one pressure member (5) and/or a pressure fluid to maintain container (3) in an inflated or partially-inflated state; and removing the pressure once the container has been drained. The drainage kit includes the viscous product (silicon mastic), a flexible container (3) and a draining device including at least one pressure member and/or pressure fluid.
