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.

1. A method of draining a flexible container holding a viscous product, comprising: selecting a viscous product having a viscosity of at least 50 Pa·s, from the group consisting of silicone oils, silicone gums, polyorganosiloxane compositions which are crosslinkable to form elastomers by polyaddition, polycondensation or dehydro(poly)condensation reactions, organic polymers comprising reactive organosilicic groups and compositions which are charged in a solvent or aqueous medium, comprise an acrylic polymer and are crosslinkable to form elastomers by drying;said method further comprising: using a flexible container of the big-bag type having a capacity between 500 and 2,000 liters and consisting of a fabric bag made of polypropylene lined with a thin multilayered bag of polyethylene/aluminum/polyethylene terephthalate adhesively bonded and/or stitched to the fabric;ensuring that at least one outlet opening, allows the viscous product to flow out of the container;exerting a pressure on at least one delimited region of the flexible container with the aid of a pressurization device to keep the container in the inflated or partially inflated state and to accelerate the flow;depressurizing at the end of draining. 2. The method as claimed in claim 1, wherein the outlet opening(s) of the container is or are obtained: by cutting out the wall of the container;and/or by removing plugs(s) or capsules fitted to one or more orifice(s), in which case said orifice(s) may be provided with spout(s) for draining the wall of the container;and/or by removing tie(s) closing opening(s) already provided on the container. 3. The method as claimed in claim 1, wherein a draining device is used comprising at least one pressure member having at least one piston and at least one drainage vessel which is intended to receive the flexible container to be drained, or only its lining bag, and is designed as a female part capable of interacting and acting as a guide for the piston of the pressure member as it moves in the forward direction corresponding to pressurization of the flexible container or only of its lining bag. 4. The method as claimed in claim 3, wherein the drainage vessel is designed so that it can be closed, and wherein the piston can be moved under the action of a pressure fluid so as to expel the viscous product out of the vessel. 5. The method as claimed in claim 4, wherein a pressure fluid contained in an inflatable jack is used, this jack being housed between the piston and a reversible closure lid of the vessel and connected to pressure fluid supply device for inflating it and consequently moving the piston, in order to make it possible to expel the viscous product out of the vessel. 6. The method as claimed in claim 1, wherein a draining device is used which comprises at least one pressurizable drainage vessel which is intended to receive the flexible container to be drained, or only its lining bag, and wherein this vessel is pressurized by a pressure fluid so as to expel the viscous product out of the vessel. 7. The method as claimed in claim 1, wherein the viscous product expelled from the flexible container, or only from its thin multilayered bag, is fed to at least one assembly for packaging said product in suitable packaging, at a suitable flow rate greater than or equal to the consumption of the packaging assembly. 8. The method as claimed in claim 1, wherein the viscous product expelled from the flexible container, or only from its thin multilayered bag, is fed to a device for storing the viscous product and/or a mechanical device for moving the viscous product in order to increase its flow rate. 9. The method according to claim 8, wherein said mechanical device is selected from the group consisting of: pumps and (double) screws. 10. The method of claim 1, further comprising a first step of moving the container to be drained from its storage site to a drainage site. 11. The method of claim 1, wherein said at least one outlet opening is in the lower part of the container. 12. The method of claim 1, wherein said pressurization device comprises at least one pressure member and/or a pressure fluid. 13. The method of claim 1, wherein said viscous product has a viscosity between 1,000 Pa·s and 10,000 Pa·s. 14. A kit for carrying out the method as claimed in claim 1, comprising: a viscous product whose viscosity is greater than or equal to 50 Pa·s, selected from the group consisting of silicone oils, silicone gums, polyorganosiloxane compositions which are crosslinkable to form elastomers by polyaddition, polycondensation or dehydro(poly)condensation reactions, and organic polymers comprising reactive organosilicic groups;a mechanically strong flexible container which is leaktight for the viscous product and which is of the big-bag type having a capacity between 500 and 2,000 liters and consisting of a fabric bag made of polypropylene lined with a thin multilayered bag of polyethylene/aluminum/polyethylene terephthalate adhesively bonded and/or stitched to the fabric;a draining device comprising at least one pressure member and/or at least one pressure fluid. 15.
