Definitions
- the present invention relates to a fluid product spray head.
- Fluid product dispensing heads particularly in the pharmacy field, are well known.
- the head generally comprises a spray profile arranged just upstream of the spray orifice.
- This spray profile can be formed by an external part, called an external nozzle, attached from the outside, as described in the documents TJS-3 625 437, EP-0 906 785, FR-1 355 350 and EP-0 412 524.
- This solution has the major drawback of a risk of expulsion of said nozzle during use.
- the object of the present invention is to provide a head for spraying a fluid product which does not have the abovementioned drawbacks. More particularly, the present invention aims to provide a spray head for a fluid which is safe and reliable and which has consistent and reproducible product spray performance and characteristics for all the heads from the same mold.
- the present invention also aims to provide a fluid product spray head which is simple and inexpensive to manufacture and assemble.
- the present invention therefore relates to a head for spraying a fluid product, comprising an expulsion channel provided with a spray orifice and with a spray profile formed in the bottom wall of said spray head, said spray profile.
- spray comprising spray channels, preferably non-radial, opening into a central spray chamber disposed directly upstream of said spray orifice, an insert being disposed in said expulsion channel to form the bottom of said spray profile, the axis central of said insert being substantially identical to the central axis of said expulsion channel, and said spray head comprising means for centering said insert.
- said expulsion channel comprises said means for centering said insert.
- said centering means comprise at least one projection, preferably three, the diameter of the fictitious inscribed circle defined by said projections being substantially identical to the diameter of the insert.
- the expulsion channel has three flats distributed symmetrically around said channel, said flats cooperating with said insert to center it relative to the expulsion channel.
- the accesses from the expulsion channel to the spray channels are made between said projections.
- the central axis of said insert is eccentric relative to the central axis of the expulsion channel by a distance less than 0.08 mm, preferably less than 0.03 mm.
- said spraying chamber has a diameter of 1 mm.
- said spray orifice has a diameter of 0.3 mm.
- the present invention also relates to a set of spray heads manufactured from the same mold imprint, said heads being produced as described above.
- the standard deviation of the eccentricities of the central axis of the insert with respect to the central axis of the expulsion channel for all the spray heads coming from the same mold imprint is less than 0.05 mm , advantageously less than 0.02 mm.
- the present invention also relates to a device for dispensing a fluid product comprising a head as described above.
- Figure 1 is a schematic view in horizontal section through the spray profile of a dispensing head according to the present invention
- Figure 2 is a schematic view in horizontal section through the expulsion channel of a spray head according to the prior art
- Figure 3 is a schematic view in horizontal section through the expulsion channel of a spray head according to an embodiment of the present invention.
- the present invention applies to all types of fluid product spray head. The present description will however be made with reference to an elongated head, for example a nasal delivery head, comprising a spray orifice directed in the axis of the head.
- the fluid spraying head comprises an expulsion channel 5 which is provided with a spraying orifice 1 and a profile spray 10 which is arranged upstream of said spray orifice 1.
- the spray profile 10 is produced in the bottom wall of the spray head and comprises in known manner, spray channels 11, preferably non-radial, leading into a central spray chamber 12 disposed directly upstream of said spray orifice 1. These channels can be three in number, as shown in FIG. 1, but another configuration is conceivable.
- An insert 20, preferably full and of simple shape similar to a rod, is provided in said expulsion channel 5 to limit the dead volume and form the bottom of said spray profile 10.
- This insert 20 is introduced from the inside of the head and therefore forms an internal nozzle for which there is no risk of expulsion of the nozzle during actuation, unlike an external nozzle, brought in from the outside of the head.
- the product flowing in the expulsion channel 5 around said insert reaches, at the front face thereof, in non-radial channels 11 via access 15.
- the product then enters the spray chamber 12 swirling before being expelled through the spray orifice 1 in the form of a spray.
- the device of the invention is therefore formed of only two parts, an external part forming the head and an internal part forming the insert.
- the present invention is characterized in that the central axis X of the insert 20 is as much as possible identical to the central axis Y of the expulsion channel 5.
- centering means for the insert 20 are preferably formed in the expulsion channel 5, near said spray profile 10.
- Us may include one or more projections adapted to cooperate with the insert 20 to center it.
- FIG. 3 shows an advantageous embodiment, in which the expulsion channel 5 has three flats 30 distributed regularly around the channel.
- the projections define a fictitious inscribed circle whose diameter corresponds approximately to the diameter of the insert 20.
- the flats could be replaced by different profiles, such as convex or concave projections, for example arcs of circles, or even several lugs distributed around the channel.
- the insert 20 being centered, the product flows approximately equally through the three channels 11 and a good spray is formed with optimal spray characteristics, both in terms of performance (average droplet size and size distribution of droplets) than consistency (reproducibility of performance for all heads).
- the manufacturing tolerances of the expulsion channel 5 and of the insert 20 can cause a slight eccentricity of the axes X and Y, but the flats 30 make it possible to limit this eccentricity.
- this is less than 0.08 mm, preferably less than 0.03 mm.
- spray heads originating from the same mold imprint have a standard deviation, as regards the eccentricity of the central axis X the insert relative to the central axis Y of the expulsion channel, less than 0.05 mm, preferably less than 0.02 mm.
- a particularly advantageous embodiment relates to a dispensing head in which the spray chamber 12 has a diameter of approximately 1 mm and the spray orifice 1 has a diameter of approximately 0.3 mm. The present invention therefore makes it possible to improve the dispensing heads of fluid product by improving the characteristics and the performances of the spray which it delivers, as well as the consistency of these characteristics.
