Abstract:
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 dip tube having a proximal end in connection with said container and a distal end connected with said tip seal, and adapted to convey said foam towards said tip seal, and wherein said tip seal is adapted to dispense said foam, the tip seal comprising: a core part defining 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 dip tube; and a cap part movably connected with said core part at said proximal end 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, wherein the cap part includes at least one dispensing orifice at a proximal end of the cap part to dispense said foam, said cap part comprising a closure element adapted for closing off said at least partially open proximal end of said core part in said closed position of said tip seal, wherein said closure element is formed as an inwardly protruding sealing cap that at least partially extends within said core part when said tip seal is in its closed position, wherein said tip seal includes a movement restriction element configured to maintain the tip seal in an open position while said foam is dispensed, said movement restriction element including a first movement restriction rim included in said core part and a second movement restriction rim included in said cap part, wherein said first and second movement restriction rims extend around at least part of the circumference of said core part and said cap part, respectively, wherein said first and second movement restriction rims are configured such that movement of said cap part relative to said core part in a direction towards said distal end of said core part is possible only when at least a minimal force is exerted on said cap part in a direction towards said distal end of said core part which is large enough to move said second movement restriction rim over said first movement restriction rim, and wherein the cap part includes a first portion and a second portion, the first portion being between the second movement restriction rim and the distal end of the cap part and the second portion being between the second movement restriction rim and the proximal end of the cap part, wherein the inner circumference of the first portion is greater than the inner circumference of the second portion.
