Tip seal having a position indicator, the tip seal being configured to dispense a foam solution

摘要

The invention relates to a tip seal (10) for an adapter (1) and such an adapter (1) for a pressurized dispensing container comprising a viscous foamable solution, said adapter (1) comprising a tube (11) in connection with said container and conveying the into foam converted viscous foamable solution towards said tip seal (10), said tip seal (10) comprising a core part (101) with an at least partially open proximal end (101a) and at least partially open distal end (101b), said core part (101) at least partially being inserted into said tube (11) at said proximal end (101a); and a cap part (102) which is movably connected with said core part (101) at said distal end (102b) of said core part (101) between an open position and a closed position of said tip seal (10), wherein said cap part (102) comprises a closure element (1021) which is adapted for closing off said at least partially open distal end (101b) of said core part (101) in said closed position of said tip seal (10).

1. A tip seal for an adapter configured to be connected to a pressurized dispensing container comprising a viscous foamable solution that is converted into foam when leaving said container, wherein said adapter comprises a tube having a distal end connected to said container and a proximal end connected to said tip seal, said tube being adapted to convey said foam towards said tip seal, said tip seal comprising:
a core part including an at least partially open proximal end and an at least partially open distal end, wherein said distal end of said core part is adapted to be inserted into said tube; and a cap part including a proximal end and a distal end, wherein said cap part includes at least one dispensing orifice at its proximal end to dispense said foam, said foam being received from said core part, wherein said cap part is movably connected with said core part at said proximal end of said core part between an open position of said tip seal in which said foam is dispensable and a closed position of said tip seal in which said foam is non-dispensable, wherein said cap part further comprises: a closure element formed as an inwardly protruding sealing cap, said closure element being positioned between said proximal end and said distal end of said cap part, said closure element extending at least partially within said core part when said tip seal is in its closed position such that said at least partially open proximal end of said core part is closed off, 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, wherein said core part further comprises an open position indicator, wherein said cap part further comprises at least one opening arranged in a side wall of said cap part between the proximal end and the distal end of said cap part, said at least one opening being positioned such that said open position indicator is only visible when the cap part is releasably secured in the open position, and wherein said position indicator includes an indicator movement restriction rim included in said core part, the indicator movement restriction rim being configured to be visible when the cap part is releasably secured in the open position.
