Tip seal adapted to dispense a foam when connected to a distal end of a tube of an adapter that is configured to be connected to a pressurized dispensing container comprising a viscous foamable solution that is converted into said foam when leaving said container, wherein said adapter comprises said tube which at its distal end (11 b) is in connection with said container and at its proximal end is connected with said tip seal, and which is adapted to convey said foam towards said tip seal, and wherein said tip seal comprises: - a core part comprising an at least partially open proximal end (101 a) and an at least partially open distal end (101 b), wherein said distal end (101 b) of said core part is adapted to be inserted into said tube; and - a cap part extending between its proximal end and its distal end and comprising at least one dispensing orifice to dispense at its proximal end said foam received from said core part, said cap part being movably connected with said core part at said proximal end (101 a) of said core part between an open position of said tip seal wherein said foam is dispensable and a closed position of said tip seal wherein said foam is non-dispensable, CHARACTERISED IN THAT said cap part comprises: - a closure element formed as an inwardly protruding sealing cap, positioned between said proximal end and said distal end of the cap part, that at least partially extends within said core part when said tip seal is in its closed position such that said at least partially open proximal end (101 a) of said core part is closed off, and in that said inwardly protruding sealing cap of said closure element of said cap part is completely extracted from within said core part when said tip seal is in said open position; and - a plurality of dispensing orifices extending around said closure element and configured to dispense said foam at said proximal end of said cap part - a core part comprising an at least partially open proximal end (101 a) and an at least partially open distal end (101 b), wherein said distal end (101 b) of said core part is adapted to be inserted into said tube; and - a cap part extending between its proximal end and its distal end and comprising at least one dispensing orifice to dispense at its proximal end said foam received from said core part, said cap part being movably connected with said core part at said proximal end (101 a) of said core part between an open position of said tip seal wherein said foam is dispensable and a closed position of said tip seal wherein said foam is non-dispensable, - a closure element formed as an inwardly protruding sealing cap, positioned between said proximal end and said distal end of the cap part, that at least partially extends within said core part when said tip seal is in its closed position such that said at least partially open proximal end (101 a) of said core part is closed off, and in that said inwardly protruding sealing cap of said closure element of said cap part is completely extracted from within said core part when said tip seal is in said open position; and - a plurality of dispensing orifices extending around said closure element and configured to dispense said foam at said proximal end of said cap part
