## Abstract

A nasal fluid dispenser device comprising: a body (10) comprising a hollow sleeve (11) and a top surface (15); and an actuator member (40) that is mounted to slide in said body (10) so as to actuate the device; the device further comprising two nasal extensions (20, 30), at least one of which forms a dispenser head provided with a respective dispenser orifice (21, 31), said nasal extensions extending from said top surface (15), each dispenser head being connected, during actuation, to a respective reservoir (50) that is arranged in said body (10), said two nasal extensions (20, 30) forming an angle lying in the range 30° to 60° relative to a longitudinal central axis (A) of said body (10).

## Claims

### Claim 1

A nasal fluid dispenser device comprising: a body (10) comprising a hollow sleeve (11) and a top surface (15); and an actuator member (40) that is mounted to slide in said body (10) so as to actuate the device; the device being characterized in that it further comprises two nasal extensions (20, 30), at least one of which forms a dispenser head provided with a respective dispenser orifice (21, 31), said nasal extensions extending from said top surface (15), each dispenser head being connected, during actuation, to a respective reservoir (50) that is arranged in said body (10), said two nasal extensions (20, 30) forming an angle lying in the range 30° to 60° relative to a longitudinal central axis (A) of said body (10).

### Claim 2 (depends on 1)

A device according to claim 1, wherein said two nasal extensions (20, 30) are parallel.

### Claim 3 (depends on 1)

A device according to claim 1, wherein said two nasal extensions (20, 30) form an angle lying in the range 40° to 50°, in particular about 45°.

### Claim 4 (depends on 1)

A device according to claim 1, wherein said two nasal extensions (20, 30) have an insertion depth lying in the range 5 mm to 15 mm, in particular about 10 mm.

### Claim 5 (depends on 1)

A device according to claim 1, wherein each reservoir (50) contains a single dose of fluid for dispensing in a single actuation.

### Claim 6 (depends on 1)

A device according to claim 1, wherein said fluid is a liquid, each reservoir (50) comprising a hollow tube containing a piston (51), each dispenser head being connected to a respective needle (25, 35), stationary in said body (10), for piercing said piston (51) during actuation.

### Claim 7 (depends on 1)

A device according to claim 1, wherein said fluid is a powder, each reservoir (50) comprising a hollow tube including an air inlet at one end and a fluid outlet at the other end, said air inlet being provided with a fluid retainer member that is adapted to retain the powder in said reservoir (50) before actuation and being connected to an air expeller that is formed by said actuator member (40), and said fluid outlet being closed before actuation by a closure element (57), such as a spherical ball, said air expeller being actuated manually by the user so as to create a flow of air that passes through said reservoir (50) so as to deliver the powder contained therein towards the dispenser orifice(s) (21, 31).

### Claim 8 (depends on 7)

A device according to claim 7, including a mechanical opening system (46, 56) that is secured to the air expeller and that is adapted to co-operate with said closure element (57) so as to expel it mechanically from its closed position while the device is being actuated.

### Claim 9 (depends on 1)

A device according to claim 1, wherein each of the two nasal extensions (20, 30) forms a dispenser head, each provided with a respective dispenser orifice (21, 31).

### Claim 10 (depends on 9)

A device according to claim 9, wherein the body (10) contains two reservoirs (50), each of which is connected to a respective dispenser head during actuation, for dispensing fluid simultaneously into both nostrils.

### Claim 11 (depends on 1)

A device according to claim 1, wherein one of the nasal extensions (20) forms a dispenser head provided with a dispenser orifice (21) for dispensing fluid into one of the two nostrils, and the other nasal extension (30) forms a guide for co-operating with the other nostril.

### Claim 12 (depends on 1)

A device according to claim 1, wherein a central portion (16) of said top surface (15) of said body (10), situated between said two nasal extensions (20, 30), comes to bear against the septum of the nose during actuation.

### Claim 13 (depends on 12)

A device according to claim 12, wherein said central portion (16) has a profile that is slightly concave so as to adapt to the septum of the nose.
