Abstract

A multiple-dose bottle (1) with a dosage spout (2) for products, particularly medicines, is of the deformable type and comprises a spout which comprises a nozzle (3) made of substantially rigid material and crossed by at least one aperture (5) for the outflow of the liquid, on which a cap (4) made of flexible material is fitted hermetically; the cap is provided with a dispending port (6) and compression of the bottle cause the liquid to seep between the nozzle and the cap.

Claims

1. 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.

2. Bottle according to claim 1, wherein said port is constituted by a substantially circular hole.

3. Bottle according to claim 1, wherein said cap is made of a rubber material which can be sterilized and is inert and impermeable to liquids.

4. Bottle according to claim 1, wherein said cap is made of a plastic material, which can be sterilized and is inert and impermeable to liquids.

5. Bottle according to claim 1, wherein said nozzle is substantially ogive-shaped.

6. Bottle according to claim 5, wherein said nozzle is made of a plastic material which can be sterilized and is inert and impermeable to liquids.

7. Bottle according to claim 1, wherein the port of said cap is substantially axial and is formed at an external protrusion which is substantially nipple-shaped.

8. Bottle according to claim 7, wherein said nozzle is axially provided with a pin for closing said protrusion.

9. Bottle according to claim 7, wherein said port is constituted by a diametrical slit of said protrusion.

10. Bottle according to claim 7, wherein said port is constituted by a star-shaped arrangement of cuts in said protrusion.

11. Bottle according to claim 7, wherein said port is constituted by a capillary tube of said protrusion.

12. Bottle according to claims 1, wherein said nozzle is rigidly coupled to the mouth of said bottle and a base of said cap surmounts said mouth.

13. Bottle according to claim 12, comprising a ring which is rigidly coupled to the mouth of the bottle and is connected, by removable sealing means, to a hood for closing said cap.

14. Bottle according to claim 12, further comprising an annular ring element which is internally provided with removable means for coupling to said ring.

15. Bottle according to claim 14, wherein said annular ring element extends downwards with a partial containment body for supporting said bottle in vertical position.

16. Bottle according to claim 14, wherein said removable coupling means are constituted by a threaded portion which can be screwed on a corresponding threaded portion of said ring.

17. Bottle according to claim 14, wherein said removable coupling means are constituted by a portion which is pressure-coupled to said ring.

18. Bottle according to claim 14, wherein said removable coupling means are constituted by a portion which is coupled by interlocking to said ring.

19. 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 the 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 nozzle is rigidly coupled to the mouth of said bottle and a base of said cap surmounts said mouth, said bottle comprising a ring for rigidly coupling the cap and the nozzle to said bottle which is secured to the base of said cap.
