Abstract:
Multiple-dose bottle with dosage spout for liquid medicine products, said bottle being deformable and said spout comprising: a nozzle sealingly connected to said bottle at a base part thereof and having an external surface ending with a top part, said nozzle being made of substantially rigid material and being crossed, at said surface, between said base and top parts thereof, by at least one aperture for the outflow of the liquid product; and a cap, made of flexible material, which covers completely said nozzle and is provided at a region thereof corresponding to said top part of the nozzle with a dispensing port, wherein said flexible cap fits elastically, all over said external surface of the nozzle, at least at a region including said at least one aperture and said nozzle top part, so as to form normally closed valve seals both at said at least one aperture and at said dispensing port, said valve seals being actuatable in an open condition upon compression of the bottle, with said cap swelling off said external surface, first at said at least one aperture and thereafter at said dispensing port, to allow the liquid product to seep out between the nozzle and the cap to said dispensing port, and again in the normally closed condition when bottle compression is discontinued, with a seal at said at least one aperture being restored first and the seal at the dispensing port being restored at a second moment, wherein said cap is thinner at its end region in order to allow the liquid to seep, while it is thicker in its intermediate region in order to secure itself hermetically against the surface of the nozzle.
