Abstract: A separation container is provided that includes a first container for storing a first substance, a second container for storing a second substance, and a frame structurally located at a periphery of the first cavity and the second cavity that supports an elastic membrane interdisposed between the first cavity and the second cavity to provide a tension seal. The elastic membrane can be completely retracted to allow the first substance to combine with the second substance responsive to a force applied to the separation container.

Abstract: The invention relates to novel viscous liquid compositions for producing pasty forms having a prolonged action and/or release for local applications. These compositions are characterized in that the long-lasting action and/or the prolonged release of the active substance is obtained by the in-situ formation of a matrix film having an increased bioadhesive power and being more or less viscous and biodegradable. The invention also relates to a viscous liquid composition with an increased bioadhesive power for a local application in pasty form with a prolonged release of an active substance, whereby being characterized in that it contains at least one matrix agent, a medium for hydrating the matrix agent, and at least one active substance.

Abstract: A separation container (110) is provided that includes a first container (111) for storing a first substance, a second container (112) for storing a second substance, and a frame (102) structurally located at a periphery of the first cavity and the second cavity that supports an elastic membrane (101) inter disposed between the first cavity and the second cavity to provide a tension seal. The elastic membrane can be completely retracted to allow the first substance to combine with the second substance responsive to a force applied to the separation container.
