Definitions
- the present invention relates to an improved dispensing head and a fluid dispensing device incorporating such a dispensing head.
- a push-button for a sprayer in which a cylindrical insert of constant section is inserted in the expulsion channel.
- the end face of the insert which is perpendicular to the axis of said insert, cooperates with the bottom of the expulsion channel to define a spray profile comprising a swirl chamber and one or more swirl channels connecting the channel of expulsion to said swirl chamber.
- said spray profile is formed in the bottom wall of said expulsion channel, while the end face of one insert is planar.
- the present invention aims to provide a dispensing head and a fluid dispensing device incorporating such a dispensing head which do not reproduce the aforementioned drawbacks.
- the present invention therefore aims to provide a dispensing head comprising a spray profile and operating in a safe and reliable manner, even with a hemispherical dispensing head end.
- the present invention also aims to provide a dispensing head comprising a spray profile, in which the risks of clogging of said spray profile are reduced.
- the present invention also aims to provide a dispensing head comprising a spray profile which can be easily molded without quality problem at the end of the head, and which allows the use of materials further reducing the risk of clogging.
- the present invention therefore relates to a device for dispensing a fluid product, comprising an expulsion channel ending in a dispensing orifice, an insert being disposed in said expulsion channel, the downstream end of said insert, in the direction product flow, defining with the downstream end portion of said expulsion channel a spray profile, said downstream end of said insert and said downstream end portion of said expulsion channel being respectively frustoconical, forming a spray profile tapered.
- said spray profile includes at least one swirl channel and a swirling, said swirl chamber being directly connected to said dispensing orifice.
- said at least one swirl channel connects the expulsion channel to said swirl chamber, the channel or channels being formed on the conical part of the frustoconical spray profile and said swirl chamber being formed on the top of the . truncated cone of the frustoconical spray profile.
- said frustoconical spray profile is formed by grooves made in the walls of the expulsion channel, said insert forming the bottom of said grooves.
- said insert fills substantially the entire volume of the expulsion channel to define a narrow expulsion channel.
- the end of said head incorporating said dispensing orifice is hemispherical.
- the present invention also relates to a device for dispensing a fluid product comprising a dispensing head as defined above.
- FIG. 1 is a schematic cross-sectional view of a dispensing head according to a preferred embodiment of the present invention
- FIG. 2 is an enlarged detail view of the dispensing head of FIG. 1.
- the present invention which mainly relates to a particular implementation of a spraying profile in a dispensing head of a fluid dispenser device, is adaptable to all fluid dispenser devices comprising a such 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 plunger. It should however be clear that the present invention is not limited to this example of application.
- the dispensing head 10 incorporates an expulsion channel 11 which extends in said head 10 between an upstream part intended to connect to the dispensing member, for example a pump, of the dispensing device on which said head will be applied, and a downstream end incorporating a dispensing orifice 12.
- an insert 20, also called an internal nozzle is placed at inside said expulsion channel, and preferably extends substantially over the whole of said expulsion channel 11.
- said insert 20 fills substantially the entire volume of expulsion channel 11, leaving only one narrow passage as an expulsion channel.
- the downstream end of the insert 20 in the direction of flow of the product, defines with the downstream end part of the expulsion channel 11 (or bottom part of the expulsion channel) a spray profile, which further promotes distribution in finely sprayed form.
- This spray profile can be any, but it generally comprises one or more swirl channels which connect the expulsion channel to a swirl chamber arranged just upstream of the dispensing orifice.
- said downstream end 21 of the insert 20 and said downstream end portion of the expulsion channel 11 are respectively of frustoconical shape, thus forming a frustoconical spray profile.
- this frustoconical spray profile has one or more swirl channels 14 and a swirl chamber 13, said swirl chamber 13 being directly connected to said dispensing orifice 12
- the swirl channel (s) 14 connect the expulsion channel 11 to the swirl chamber 13, but unlike the device of the prior art, said spray profile 13 and 14 is not produced in a plane transverse to the longitudinal axis of the pusher.
- the swirl channel (s) 14 are advantageously formed on the conical part of the frustoconical spray profile while said swirl chamber 13 is advantageously formed on the top of the frustum of said frustoconical spray profile.
- this implementation makes it possible to increase the length of said swirl channels 14, even when the end of the head 10 is produced in a hemispherical manner, which can be the case with a nasal plunger.
- the presence of the frustoconical spray profile of the invention makes it possible to avoid any quality problem during the molding of the end of the head, which therefore facilitates the manufacture of that -this.
- the frustoconical swirl profile of the invention that is to say the swirl channel or channels 14 and the swirl chamber 13, is formed inside the frustoconical bottom wall of the expulsion channel 11, while the insert 20 has a smooth outer surface. After its installation inside the expulsion channel, said insert 20 then forms the bottom of said grooves of the swirl profile.
- This implementation prevents any risk of deterioration of the swirl profile during assembly of the insert. inside the expulsion channel.
- the present invention therefore makes it possible to provide a dispensing head comprising a spraying profile, particularly suitable for pushers of the nasal type, and which has the following advantages: - the pushbutton can be produced with a hemispherical end, which favors the use both in adults and children, with no problem of molding quality at the end of the head;
- the insert can be made of a material, such as prolypopylene or acetal, which makes it possible to further reduce the risk of clogging of the pusher.
- the dispensing head of the invention in particular as described above with reference to the figures, naturally adapts to any type of device for dispensing an appropriate fluid.
