Abstract

The invention refers to a bottle for containing fluids, particularly for pharmaceutical products or the like, which comprises a fluid container (2) made in a deformable material and which features a mouth for the passage of fluid, a valve (5) in an elastically deformable material that defines a flexible inner chamber arranged in proximity of the mouth, a cap (7) that substantially fits on and seals the valve and which features a dispensing opening for the fluid, and a containment ring (14) placed between said cap and said valve, arranged so that it externally embraces a portion of the valve and able to limit its deformation. A squeezing of the container causes the fluid to push up towards the mouth, the valve to compress, the fluid to flow between the valve and the cap and then to come out through the dispensing opening.

Claims

1-31. -31. (canceled)

32. A bottle for containing fluids, comprising a fluid container made of a deformable material and which includes a mouth for passage of said fluid, a valve of an elastically deformable material that defines a flexible inner chamber arranged in proximity of said mouth, a cap that substantially fits on and seals said valve and which has a dispensing opening for dispensing said fluid, the squeezing of the container causing the fluid to push up towards the mouth, the valve to compress, the fluid to flow between the valve and cap and to come out through said dispensing opening, and a containment ring placed between said cap and said valve and arranged to externally embrace at least one portion of said valve and able to limit deformation thereof.

33. The bottle according to claim 32, wherein said valve is bell shaped and includes a first open section substantially tubular in shape, and a second closed section which can be positioned in proximity of said dispensing opening.

34. The bottle according to claim 33, wherein said containment ring is arranged to externally embrace said first section.

35. The bottle according to claim 32, including supporting and closing means for supporting said valve and for closing said inner chamber, which can be associated with at least one between said cap and said container.

36. The bottle according to claim 35, wherein said containment ring is a body separate from said supporting and closing means.

37. The bottle according to claim 35, wherein said containment ring is one piece with said supporting and closing means.

38. The bottle according to claim 35, wherein said supporting and closing means comprise at least one sealing element placed in between said mouth and said valve and includes at least one hole for the passage of the fluid.

39. The bottle according to claim 38, wherein said sealing element comprises an inner ring-shaped projection facing said container and able to couple to said container'"'"'s mouth.

40. The bottle according to claim 38, wherein said sealing element comprises an outer ring-shaped projection facing said valve and able to couple to and seal the inner surface of said first valve section.

41. The bottle according to claim 39, wherein said sealing element comprises a peduncle that extends inside said inner ring-shaped projection, between said peduncle and said inner ring-shaped projection being defined a guiding space for the fluid leaving the container.

42. The bottle according to claim 38, wherein said sealing element comprises:

an inner ring-shaped projection facing said container and able to couple to said container'"'"'s mouth;

an outer ring-shaped projection facing said valve and able to couple to and seal the inner surface of said first valve section; and

a peduncle that extends inside said inner ring-shaped projection between said peduncle and said inner ring-shaped projection being defined a guiding space for the fluid leaving the container;

said inner ring-shaped projection, said outer ring-shaped projection and said peduncle being defined substantially coaxial to one another.

43. The bottle according to claim 40, wherein:

said valve is bell shaped and features a first open section, substantially tubular in shape, and a second closed section which can be positioned in proximity of said dispensing opening; and

said containment ring is integrally associated with said sealing element and extends substantially around said outer ring-shaped projection, a housing space of said first valve section being defined between said containment ring and said outer ring-shaped projection.

44. The bottle according to claim 35, wherein said supporting and closing means comprise at least one wall of said container, said mouth being defined by at least one through slot obtained on said wall.

45. The bottle according to claim 44, wherein:

said valve is bell shaped and features a first open section, substantially tubular in shape, and a second closed section which can be positioned in proximity of said dispensing opening; and

said wall comprises a ring-shaped relief, facing said valve and able to couple to and seal the inner surface of said first section of the valve.

46. The bottle according to claim 45, wherein said containment ring is integrally associated with said wall and extends substantially around said ring-shaped relief, a housing space of said first valve section being defined between said containment ring and said ring-shaped relief.

47. The bottle according to claim 33, wherein said valve comprises a ring-shaped flap which extends around the open end of said first section and features at least one fluid passage gap.

48. The bottle according to claim 33, wherein said second valve section comprises a plurality of first longitudinal ribs obtained in relief on the inner side surface of said second section of the valve.

49. The bottle according to claim 33, wherein said second valve section comprises a plurality of second longitudinal ribs obtained in relief on the outer side surface of said second section, a bed for the passage of said fluid being defined between two successive second ribs.

50. The bottle according to claim 32, including a closing plug which can be associated with said cap.

51. The bottle according to claim 50, wherein said closing plug comprises a substantially hollow cylindrical body, able to be fitted around said cap.

52. The bottle according to claim 50, wherein said closing plug comprises an internal appendix which, in the closing configuration, fits on said cap by the edge of said dispensing opening.

53. The bottle according to claim 50, wherein said closing plug comprises sealing means, which can be associated with the inner surface of the plug and able to rest against the edge of said dispensing opening in the closing configuration.

54. The bottle according to claim 50, wherein said closing plug comprises:

an internal appendix which, in the closing configuration, fits on said cap by the edge of said dispensing opening; and

sealing means, which can be associated with the inner surface of the plug, are able to rest against the edge of said dispensing opening in the closing configuration, and comprise a bearing in a deformable material housed in said internal appendix.

55. The bottle according to claim 50, wherein said closing plug is associated along a plurality of lacerable portions with a sealing ring nut integral to said cap or said container.

56. The bottle according to claim 50, wherein said closing plug is associated with said cap along a plurality of breaking lines.

57. The bottle according to claim 50, wherein said closing plug comprises a top that can be connected, in a removable way, to the edge of said dispensing opening.

58. The bottle according to claim 32, including a check valve body defined in proximity of said dispensing opening and which allows said fluid to flow from said container outwards and to prevent it coming back.
