Definitions

  • the present invention relates to a dispensing head improved nasal and product delivery device fluid incorporating such a dispensing head.
  • a sprayer plunger in which an insert cylindrical of constant section is inserted in the channel expulsion.
  • the end face of the insert which is perpendicular to the axis of said insert, cooperates with the bottom the expulsion channel to define a profile of spray comprising a swirl chamber and one or more swirl channels connecting the expulsion channel to said swirl chamber.
  • said spray profile is provided in the bottom wall of said expulsion channel, while the face end of the insert is flat.
  • This type of device can however be present in some cases of disadvantages. So in the case of a nasal pusher, it may be desirable to carry out said pusher with a hemispherical end. This can pose a problem during molding, especially when the volume of the swirl chamber is weak. Indeed, the combination of a hemispherical end with a profile horizontal spraying transverse to the axis longitudinal of the head can pose problems in particular at the thickness of the wall of the end of the head. A solution is then to reduce the dimension transverse of the expulsion channel and the insert, and therefore the dimension of the spray profile. This generates however an increased risk of blockage of the pusher at said spray profile.
  • the object of the present invention is to provide a head nasal delivery device and a delivery device fluid product 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 safely and reliably, even with a hemispherical dispensing head end.
  • the present invention also aims to provide a distribution head comprising a profile of spraying, in which the risks of clogging of said spray profile are decreased.
  • the present invention also aims to provide a dispensing head comprising a spray profile which can be easily molded without any 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 head of nasal delivery for a delivery device fluid product, said head comprising an expulsion channel ending with a dispensing orifice, an insert being disposed in said expulsion channel, the end downstream of said insert, in the direction of flow of the product, defining with the downstream end portion of said channel spray profile, characterized in that that said downstream end of said insert and said part downstream end of said expulsion channel are respectively frustoconical, forming a profile of frustoconical spray, said filling insert substantially the entire volume of the expulsion channel to define a narrow expulsion channel.
  • said spray profile comprises at least one swirl channel and one swirling, said swirl chamber being directly connected to said dispensing orifice.
  • said at least one channel swirl connects the expulsion channel to said swirl chamber, the channel or channels being formed on the conical part of the spray profile frustoconical and said swirl chamber being formed on the top of the truncated cone of the profile frustoconical spray.
  • said spray profile frustoconical is formed by grooves made in the walls of the expulsion channel, said insert forming the bottom said grooves.
  • the end of said head incorporating said dispensing orifice is hemispherical.
  • the present invention also relates to a fluid dispenser device comprising a distribution head as defined above.
  • the present invention which mainly relates to a special implementation of a spray profile into a nasal delivery head of a delivery device distribution of fluid, is adaptable to all fluid dispensing devices comprising a such spray profile.
  • the present invention relates to nasal delivery devices, and will described with reference to a particular nasal plunger. he should be made clear, however, that the present invention does not not limit to this application example.
  • the dispensing head 10 incorporates an expulsion channel 11 which extends into said head 10 between an upstream part intended to connect to the distribution member, for example a pump, distribution device on which said head will be applied, and a downstream end incorporating a distribution 12.
  • an insert 20 also called a nozzle internal, is placed 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 the canal expulsion 11, leaving only a narrow passage as that expulsion channel.
  • the downstream end of the insert 20 in the product flow direction, defined with the downstream end part of the expulsion channel 11 (or part bottom of the expulsion channel) a spray profile, which further promotes distribution in the form finely sprayed.
  • This spray profile can be any, but usually has one or more swirl channels which connect the expulsion channel to a swirl chamber located just upstream of the dispensing orifice.
  • said downstream end 21 insert 20 and said downstream end portion of the expulsion channel 11 are respectively frustoconical in shape, thus forming a frustoconical spray profile.
  • this spray profile frustoconical has one or more channels of swirl 14 and a swirl chamber 13, said swirl chamber 13 being directly connected to said distribution 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 spray profile frustoconical while said swirl chamber 13 is advantageously formed on the top of the truncated cone of said frustoconical spray profile.
  • this implementation allows to increase the length of said swirl channels 14, even when the end of the head 10 is made of hemispherical way, which can be the case with a nasal pusher.
  • 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 it.
  • the swirl profile frustoconical of the invention that is to say the channel (s) of swirl 14 and the swirl chamber 13, is formed inside the frustoconical bottom wall of the expulsion channel 11, while insert 20 has a surface smooth exterior. After its installation inside the expulsion channel, said insert 20 then forms the bottom said grooves of the swirl profile. This bet implemented prevents any risk of deterioration of the profile swirl when assembling the insert to inside the expulsion channel.
  • the distribution head of the invention in particular as described above with reference to the figures, adapts of course to any type of device distribution of suitable fluid.
