- said upstream portion of the insert is mounted by clamping in said internal part of the body.
- said internal portion of the body comprises an internal radial shoulder, said upstream portion of the insert being abutted on said shoulder to maintain the insert in said internal part of the body.
- said upstream portion of the insert comes into contact with the dispensing member when the spray head is assembled on said dispenser member.
- said elastically deformable portion of the insert is deformed during assembly of the spray head on said dispensing member.
- said downstream portion of the insert comprises a portion of reduced diameter axially offset from the downstream end of said insert, to form a chamber in the expulsion channel near said spray profile, so that said downstream end of the The insert may at least partially pivot relative to said reduced diameter portion, generating a ball-and-socket effect.
- said elastically deformable portion of the insert is disposed at the upstream end of said insert.
- the present invention also relates to a fluid dispenser device comprising a dispensing member, such as a pump, and a spray head as described above, assembled on said dispensing member.
- FIGS. 1 to 5 are schematic cross-sectional views of a spray head according to various advantageous embodiments.
- Figures 6 to 13 are schematic views of several embodiments of an insert used in a spray head according to the invention.
- the present invention which mainly concerns a particular implementation of a spray profile in a dispensing head of a fluid dispenser device, is adaptable to all fluid dispensing devices comprising such a spray profile.
- a particularly advantageous application of the present invention relates to nasal delivery devices, and the present invention will therefore be described with reference to a nasal pusher. It should be clear, however, that the present invention is not limited to this application example.
- a spray head 1 comprising a body 10 which incorporates an expulsion channel 1 1 which extends in said body 10 between an upstream part intended to connect to the dispensing member, for example a pump, the dispensing device on which said spray head 1 will be applied, and a downstream end incorporating a dispensing orifice 12.
- body 10 may comprise an inner sleeve 101, which defines the expulsion channel, and an outer portion 102.
- an insert 20, also called internal nozzle is placed inside said expulsion channel January 1, and preferably extends substantially over a large part of said expulsion channel January 1.
- said insert 20 substantially fills the volume of the expulsion channel 11, leaving only one or more narrow passage (s) as an expulsion channel.
- the downstream end of the insert 20, in the flow direction of the product defines with the downstream end portion of the expulsion channel 1 1 (or bottom portion of the expulsion channel) a spray profile, which promotes a distribution of the fluid in finely pulverized form.
- This spray pattern may be of any shape, but it generally has one or more swirl channels that connect the expulsion channel to a central swirl chamber disposed just upstream of the dispensing orifice.
- the spray head 1 is intended to be associated with a dispensing member 2, such as a pump, a part of which is schematically represented in FIGS. 4 and 5.
- the insert 20 comprises an elastically deformable portion 21, adapted to deform, for example to absorb deformations of the body 10 of the spray head 1, deformations that may be due to shocks or creep materials .
- This elastically deformable portion 21 of the insert 20 thus generates a spring effect to compensate for the dimensional variations of the body 10 of the spray head 1.
- the elastically deformable portion 21 may also act to absorb and / or compensate for dimensional variations of said insert 20, and / or to compensate for deformations and / or displacements of said insert 20 in said body 10, for example during a displacement of the piston 2 may cause over-stress on the insert or a game or a displacement of said insert.
- FIGS. 1 and 6 to 13 illustrate various possible structural shapes to achieve this spring function in the elastically deformable portion 21 of the insert 20.
- This elastically deformable portion 21 of the insert 20 also provides a good definition of the geometry of the spray profile, by applying a certain pressing force on the downstream end of the insert 20, against the downstream end portion of the expulsion channel 1 1 (or part of the bottom of the expulsion channel). This guarantees a correct positioning in all circumstances of the insert 20 in the inner sleeve 101 defining the expulsion channel January 1.
- the elastically deformable portion 21 of the insert 20 also allows to pre-assemble the insert 20 in the body 10 of the spray head, and not to put in contact the insert with the bottom of the spray channel (or alternatively to increase the contact force) only when the spray head is assembled on the pump.
- FIG. 1 represents an advantageous embodiment, in which the elastically deformable part 21 is formed by deformable material bridges connecting an internal part 201 of the insert 20 extending inside the internal sleeve 101 of the body 10 to an outer portion 202 of the insert 20 which remains outside said inner sleeve 101.
- This outer portion 202 may in particular be fixed to the pump, and comprise an axial sleeve 203 extending axially around a portion of said inner sleeve 101 of the body 10, as well as a radial flange 204, which may be in contact with an inner surface of said outer portion 102 of said body 10.
- this axial sleeve 203 and / or said radial flange 204 are not necessarily associated with said bridges of deformable material connecting the inner portion 201 to the outer portion 202.
- the insert 20 can deform at the level of said deformable material bridges, and thus absorb these variations, while maintaining a correct contact with the bottom of the expulsion channel, to ensure the integrity of the spray profile.
- the insert 20 is entirely placed inside the internal sleeve 101 of the body 10, and therefore does not include an external part as in FIG.
- the insert 20 comprises an upstream portion 25 and a downstream portion 26, in the direction of flow of the fluid, which are interconnected by said elastically deformable portion 21.
- the lower part is held in the inner sleeve 101 by clamping.
- one or more internal and / or external fluid passages are provided in this lower portion to allow the fluid to pass.
- said internal portion 101 of the body 10 has an internal radial shoulder 103, said upstream portion 25 of the insert 20 abutting said shoulder 103 to hold the insert 10 in said inner portion. 101 of the body 10.
- said upstream portion 25 of the insert 20 comes into contact with the dispensing member 2, in this case the output of the pump, when the spray head 1 is assembled on said 2.
- said elastically deformable portion 21 of the insert 20 is deformed during this assembly of the spray head on said dispensing member. This optimizes the contact between the insert 20 and the body 10, to define the spray profile, only at the time of assembly.
- said downstream portion 26 of the insert 20 may comprise a part of reduced diameter 28 shifted axially of the downstream end 27 of said insert 20, to form a chamber 15 in the expulsion channel 1 1 near said spray profile.
- said downstream end 27 of the insert 20 can at least partially pivot relative to said reduced diameter portion 28, generating a ball-and-socket effect, which further enables the contact between the insert 20 and the bottom of the channel to be further optimized. of expulsion 1 1. This allows in particular to compensate for a defect of perpendicularity between the insert and the bottom of the head.
- Figures 6 to 13 show various alternative embodiments for the elastically deformable portion 21 of the insert.
- FIG. 10 shows an example in which said elastically deformable portion 21 of the insert 20 comprises an overmolded part 220 of deformable material. This overmoulded part may also be disposed at the upstream end of said insert 20.
- said elastically deformable portion 21 of the insert 20 has one or more radial openings 230, in this case three, passing through said insert 20.
- FIGS. 7 and 8 show an elastically deformable portion 21 of the insert 20 which comprises at least one strip of inclined deformable material 240.
- FIG. 7 there is an S-shaped blade, whereas in FIG. there are two X-shaped bands.
- the present invention therefore makes it possible to provide a spray head comprising a spray profile, particularly suitable for nasal sprays, and which has the following advantages in particular: - resistance to drops tests, including those provided in ISO 20072, the insert having the ability to absorb violent shocks;
- the insert can absorb creep stresses exerted on it by the body of said spray head.
- the spray head of the invention especially as described above with reference to the figures, of course adapts to any type of suitable fluid dispensing device.
