Abstract:
Multi-chamber ampoule for measured doses of liquids comprising:an outer sleeve (2) of elastic material having a first chamber (12) extending along an axis (y), closed at its lower end by a first bottom (31), and a third opening (25) at its upper end;a closure element closing said outer sleeve (2) at said third opening (25), wherein;said closure element consists of an inner sleeve (3) comprising a second chamber (13), a second bottom (30) at its lower end, an outer surface, and a first opening (33) at its upper end;a micro brush (1) has a liquid-absorbing element at its tip (10) and can be inserted and removed from said inner sleeve (3) through said first opening (33);said micro brush (1) is removably supported in said inner sleeve (3) and a liquid-tight seal is formed between said micro brush (1) and said inner sleeve (3) when said micro brush (1) is inserted into said inner sleeve (3);said inner sleeve (3) is slidable along axis (y) in said outer sleeve (2) and forms a liquid-tight seal between said inner sleeve (3) and said outer sleeve (2);said inner sleeve (3) has, in spaced relationship relative to said first bottom (30), radial bores (15) through said inner sleeve (3) providing a passage from said second chamber (13) to said outer sleeve (2);said second bottom (30) of said inner sleeve (3) is positionable in spaced relationship to said first bottom (31) of said outer sleeve (2);a plurality of locking elements are provided locking said inner sleeve (3) relative to said first bottom (31) of said outer sleeve (2) at an upper and a lower height position;said upper height position of said inner sleeve (3) defines a storage position and said lower height position of said inner sleeve (3) defines a discharge position;said tip (10) of said micro brush (1) is arranged near the bottom of said second chamber (13) of said inner sleeve (3);an annular lower sealing lip (7) and a corresponding lower sealing groove (8) are disposed between said outer sleeve (2) and said inner sleeve (3); andsaid lower sealing lip (7) and said lower sealing groove (8) are disposed above said first chamber (12) which is filled with a second liquid (17).
