Abstract
A case (1) is filled by pouring, in the liquid phase, at least two products A and B, the case having a base (2) and a lid (4). The method includes the steps of installing within the case a thin membrane (5) made of a material which is soluble in the solvent of at least one of the products, the membrane (5) being arranged in a manner such as to define, within the case, at least a first space (6) and a second space (7), the first and second spaces (6, 7) being isolated from each other over at least part of the axial height of the case, pouring the product A into the first space (6) and the product B into the second space (7), and allowing the products to dry in a manner such as to set the products, the membrane (5) becoming solubilized in the solvent during the setting of the products A and B within the first space (6) and the second space (7), respectively.
