Definitions
- the present invention relates to a spraying tip for liquid or semi-liquid product.
- the invention relates more particularly to spraying tips equipping distributors of pharmaceutical or cosmetic products such as nasal sprays.
- Known tips generally comprise an elongated outer part provided at the bottom of a pusher base and an inner distribution duct feeding, at the top, an end nozzle and connected, in the lower part, to the tube.
- ejection means for delivering the product under pressure such as a pump or a valve, mounted on the neck of a bottle containing the product.
- This discontinuity is detrimental to the comfort of consumers and the assimilation of the product in the case of a drug.
- the object of the invention is to solve this problem by providing the tip with a specific structure with reinforced sealing.
- a tip characterized in that said tip comprises a needle valve ensuring the sealing of the spray orifice formed at the end of said tip, fastening means on the ejection tube and means for supplying the product to a vortex chamber located in the vicinity of said orifice.
- the fixing means consist of a tip barrel, one end of which has a ring connecting the ejection tube of the delivery means.
- the upper end of the ejection tube is provided with a socket engaging in the said ring, the diameter of said ring being such that it can receive said sleeve in radial clamping.
- said barrel comprises a backing chamber hermetically sealed by a peripheral sealing ring carried by a base of said needle valve.
- the endpiece comprises a chamber for controlling the sealing of the rearing chamber that can be placed in communication with pneumatic measuring means.
- said means for feeding the product to said vortex chamber comprise a fixed core traversed by a central bore for guiding an axial rod integral with said valve, said core presenting connecting means with said barrel and leaving a terminal channel which opens, in the upper part, laterally in the vortex chamber.
- said liquid supply means comprise an upstream liquid supply channel which is formed through said barrel, and whose inlet orifice is situated in the vicinity of the fastening means on the barrel. ejection while the outlet opens out of said barrel.
- the endpiece comprises an inner sleeve in which said shaft is fitted.
- said inner sleeve has a diameter greater than that of said barrel so as to define an intermediate annular space for said liquid product, said passage constituting at least partially the means for feeding said product from the end of the ejection tube until in the vicinity of said spray orifice.
- the tip has a peripheral bearing zone formed in the vicinity of its fixing means on the end of the ejection tube.
- the tip of the invention provides a reinforced seal and thus ensures the physico-chemical properties and the sanitary quality of the product regardless of the volume of the bottle and doses delivered.
- the internal needle valve is compact and integrates particularly well with the structure of the nozzle while contributing, by a sudden rupture of the seal in the manner of a valve, to obtain, when spraying, a very fine and intense dispersion of the product.
- the tip of the invention separates the guide functions of the moving needle and circulation of the product in the end channel supplying the inner nozzle.
- the profile of the channel is not modified and the passage sections of the product remain constant during the entire stroke of the needle, which guarantees the stability of the feed parameters (speed, pressure ) of the nozzle and therefore the regularity and homogeneity of the spray.
- connection of the nozzle to the delivery means is particularly simple and stable which ensures easy handling and allows, when actuated by pushing, to maintain the axial alignment of the tip on the bottle which is a condition necessary to perform a reliable and accurate dosing.
- Figure 2 shows a sectional view of the embodiment of Figure 1 mounted on a pump itself assembled to a bottle;
- FIGS. 3A to 3D represent the tip of the preceding figures during the different phases of the distribution of the product
- FIG. 4 represents an exploded perspective view of the tip of the preceding figures.
- the tip shown in Figures 1 to 4 has an outer casing 5 of revolution and central axis delimiting, at least in the upper part, the wall of an inner conduit 50 which opens upwardly via an orifice of small diameter spray 50a and extends downwardly by an inner sleeve 51.
- the outer casing 5 has a lower skirt 52 which covers the neck of the bottle as shown in FIG. 2.
- a removable cover C may advantageously cover the upper part of the casing 5 as also shown in FIG.
- the casing 5 of the nozzle has a concave peripheral zone 53 formed in the vicinity of its fastening means on the end of the ejection tube E and allowing the manual support on the tip to actuate the product delivery means .
- the tip comprises a valve housed in the duct 50 and which is provided with a needle 1 whose upper end 1a cooperates with the outlet orifice 50a of the vortex chamber 54 forming the spray nozzle.
- the end 1a carries a lug whose profile is complementary to that of the orifice 50a in which it penetrates to come seal it sealingly in the manner of a plug.
- the lower end 1b of the needle 1 cooperates with a return coil spring 2 which is carefully calibrated as a function of the desired pressure threshold at the opening of the valve and the desired parameters of the spray jet.
- the swirl chamber 54 is located inside the nozzle in the vicinity of the orifice 50a and comprises tangential grooves formed on the inner wall of the nozzle.
- the needle 1 consists of an axial rod 12 extending downwards by a base 13 carrying a peripheral ring 13a and then by a lower pin 14 for setting and centering engaged in the spring 2.
- the inner conduit 50 is provided with a substantially cylindrical core 3.
- a central bore 31 for guiding in which is slidable the axial rod 12 of the needle 1.
- the core 3 is immobilized in its upper housing by radial clamping and its upper face partially closes the grooves of the swirl chamber 54 which open laterally in a terminal channel 30 for conveying the product, delimited between a longitudinal flat portion 32 of the core 3 and the wall of the inner conduit 50 of the nozzle.
- the endpiece comprises a shank 4 made here in the form of an insert which is engaged in the internal conduit 50.
- the lower end of the shank 4 carries a ring 41 connecting the ejection tube E with a means of delivery of pressure product of the pump type P or valve (see Figure 2).
- the end of the ejection tube E is provided with a bushing D with an upper outlet orifice of the pressurized liquid which is fitted into the connecting ring 41 of the drum 4.
- the diameter of the ring 41 is such that it can receive the sleeve D in sealed radial clamping.
- the barrel 4 delimits a recoil chamber 20 in which the spring 2 is housed and which is hermetically closed in the upper part by the base 13 and the sealing ring 13a of the moving needle 1.
- the barrel 4 comprises a transverse plate 42 offering a bearing surface at the end turn of the spring 2 inside the chamber 20 and surmounting an enclosure 43 which allows the control of the seal by placing in communication with pneumatic measuring means.
- the enclosure 43 has a lateral orifice 44 which allows, on the one hand, the escape of the compressed air during the introduction of the needle 1 into the drum 4 and, on the other hand, the possible taking of the pressure to check the seal between the base 13 and its sealing ring 13a with the barrel 4.
- the barrel 4 is fitted into the inner pipe 50 until the ring 41, whose diameter is greater than that of the barrel, comes into abutment upwards against the lower edge of the inner sleeve 51.
- the edge of the sleeve 51 bears against radial shoulders 33 carried by the core 3, which ensures that it is held and wedged in the duct 50 and guarantees the integrity of the pre-compression cell 10.
- the core 3 also comprises means of connection with the barrel 4 in the form of a set of anchoring studs 34 nested in the upper part of the barrel 4 by delimiting a pre-compression cell 10 of the product which is located under the core 3 and above the base 13.
- the cell 10 feeds the end channel 30 into product and the internal pressure in this cell controls the displacement of the needle 1 and thus the opening and closing of the valve.
- the feed means for the product further comprise, in the lower part, an upstream liquid supply channel 40 which is formed inside the drum 4.
- the upstream channel 40 is parallel to the axis of the nozzle and has an inlet at its lower end which is located inside the connecting ring 41 while at its upper end, the outlet orifice opens laterally into the intermediate annular space 60 situated between the outer wall of the shaft 41 and the inner wall of the sleeve 51.
- the bottom of the ring 41 is provided with a cavity 45 forming a dead volume opposite the end of the outlet orifice of the sleeve D and in which is formed the inlet orifice of the channel 40.
- the space 60 communicates at the top with the cell 10 and with the terminal channel 30.
- FIGS. 3A to 3D show the progression of the liquid product in the various sections of the feed means during the ejection of the pressurized product by pressing on the nozzle.
- the opening of the needle valve takes place when the pressure in the cell 10 reaches a certain threshold causing the needle 1 to descend into the chamber 20 and the vortex chamber 54 is under load as shown in FIG. 3D.
