Definitions

  • the present invention relates to a device for distribution of fluid, and more particularly, the present invention relates to such a device distribution comprising an actuated closure system automatically when the device is activated distribution.
  • the closure system of the present invention applies to all distribution devices fluid product, and in particular to distribution comprising a pump or a valve connected to a tank and actuated by an actuating means such than a pusher.
  • the object of the present invention is to provide a obturation system for a distribution device fluid product which does not have the disadvantages supra.
  • the present invention therefore aims at a system shutter which provides a perfect shutter of the fluid dispensing device avoiding thus any contamination and / or drying of the product in level of the dispensing orifice.
  • the present invention also aims to provide a shutter system which is automatically opened at moment of actuation of the dispensing device of fluid product.
  • Another object of the present invention is such a shutter system which is completely separate from the part of fluid circulation in the organ of distribution and which therefore does not interfere with creation of the spray and / or with priming necessary from the device.
  • the present invention therefore relates to a fluid dispenser device comprising a distribution member, such as a pump, means ejection nozzle such as an ejection nozzle incorporating a dispensing orifice, an actuating means such than a pusher, and a shutter system comprising a elastically deformable closure element between a shutter position, in which it seals hermetically the dispensing orifice and a position opening in which it opens the orifice of distribution, characterized in that said pusher is slightly displaceable relative to said nozzle ejection and in that the closure element is disposed between said pusher and said ejection nozzle, so that upon actuation of the distribution, the closure element is deformed towards its position of opening by said ejection nozzle by a member secured to said ejection nozzle, said obturation element returning elastically towards its shutter position after actuation of the device of distribution.
  • a distribution member such as a pump
  • means ejection nozzle such as an ejection nozzle incorporating a dispens
  • the closure element comprises a deformable closure wall which closes the orifice of distribution, said closure wall comprising opening means which open in the position opening the shutter element.
  • the opening means comprise a slot which opens when the device is actuated of distribution.
  • said closure wall comprises a substantially concave lower surface which is, in the closed position, in contact with a convex upper surface of the member secured to the distribution device.
  • said slot is defined by two edges that move away when opening the slot so as to form a truncated cone in the position opening of the shutter element, the more part small diameter of said truncated cone being defined by the lower ends of said two edges located at close to the dispensing orifice, so that when the slot closes, the two edges enter first in contact at said ends lower, expelling the product outward remaining in the truncated cone after actuation of the distribution device.
  • said lower ends of the two edges scrape said convex upper surface of the integral member from the dispensing device, removing the product remaining there after actuation of the device of distribution.
  • said closure element comprises a cylindrical sleeve disposed around and / or fixed to said ejection nozzle, and a closure wall deformable forming an end wall of said sleeve, said closure wall having a slot disposed next to the dispensing opening and which opens upon actuation of the device.
  • said sleeve is, in the position opening of the shutter element, deformed in such a way so as to elastically stress the element shutter to its shutter position.
  • the closure element is produced in the form of a disc with a hole which is closed in position shutter, and which opens to let an organ pass secured to the distribution device when said dispensing device is activated.
  • said closure element is made of an elastomeric material, such as rubber butyl.
  • shutter system of this invention applies to any type of device distribution of fluid, this description will be made in relation to a spraying device comprising a pump and actuated by a pusher.
  • the device fluid product distribution comprises a pump 20, which can be any standard pump and which will not therefore not described in more detail below, said pump being on the one hand connected to a product reservoir (not shown) and on the other hand to a dispensing orifice 8 via an expulsion channel 2 and 5.
  • the pump is actuated by an actuating means such as a pusher 1 which, together with the outlet part of the channel 2, defines a dispensing head.
  • the head of the spray device is split in half main components, a body 1, integral with the pusher, and an ejection nozzle 3. In a device for standard spray, this nozzle is usually made in one piece with said body.
  • the separation of these two components is made to allow the introduction of a closure element 4 therebetween, that is to say between the body 1 of the dispensing head and the ejection nozzle 3.
  • An insert 2 forming a nozzle having the function of reducing dead volume and creating the appropriate channel shape to achieve good spray, is as usual inserted by pressure in the ejection nozzle element 3, and therefore forms the end of the expulsion channel, the other side being disposed on the outlet tube 5 of the pump 20.
  • the shutter system of the present invention also works with distribution heads comprising no ejection nozzle incorporating a nozzle. It suffices that the shutter element 4 can be disposed between the body 1 and a member secured to the pump, provided that this member secured to the pump can move relative to said body 1, like this will be described below.
  • the single ejection nozzle 3 / insert 2 is assembled in body 1 so that it can slide in the body 1 with a limited stroke, and this unit is prevented from accidental separation from said audit body 1 in any suitable manner, in particular by snap-fastening.
  • the closure element 4 is preferably made of a suitable elastomer, such as butyl rubber, which is tightly assembled on the ejection nozzle 3.
  • This closure element 4 preferably comprises a part of tubular sleeve 40 which ends at a end by a closure wall 41 forming a wall of Bottom of said sleeve 40.
  • said part of sleeve 40 is mounted and / or fixed around said nozzle ejection 3, advantageously by means of a fixing by a sort of snap 42, and said closure wall 41 covers and seals the orifice distribution 8 of the device.
  • Said shutter element 4 is provided in its closure wall 41 with means openings 6, advantageously produced in the form a slot, which is arranged opposite said orifice distribution 8.
  • this slot is kept closed from tightly to prevent contamination and / or drying of the product remaining in or near the dispensing orifice 8 after actuation of the distribution device.
  • the closure element 4 is maintained at the level from the peripheral edge of its closure wall 41, by a rib 11 of body 1, which cooperates with a groove corresponding provided in said closure wall 41. This advantageous characteristic allows, in the position shutter the shutter element, to exercise a radial force on said closure wall 41, so that the slot 6 is kept sealed in said closed position.
  • said slot 6 is defined in the obturation wall 41 by two edges 61, 62, shown in FIGS. 5 and 7, which come into tight contact each other in the element's closed position shutter 4.
  • the sleeve 40 of Elemenc shutter 4 can be made in such a way as to to be able to deform. So when the shutter element 4 is in its open position, this deformation of the sleeve 40 urges the closure element towards its shutter position thus bringing back this element shutter in its shutter position after actuation of the device.
  • the closure system of the present invention works as follows.
  • the sealing element seals the orifice distribution 8 of the pump, so that any contamination and / or drying of the product remaining in this pump is prevented.
  • this pressure exercised downward in the figures results in a relative movement between body 1 and nozzle unit ejection 3 / insert 2.
  • the sleeve 40 of the closure element 4 deforms elastically and the ejection nozzle simultaneously deforms the wall shutter 41 by opening the slot 6 upwards, as shown in Figures 2, 5 and 7.
  • the assembly formed by the ejection nozzle 3 / insert 2 unit and the pusher 1 is returned to its initial position by the spring of pump recall and due to spring action exerted by the sleeve 40 of the closure element deformed. Therefore, the shutter element 4 resumes its closed position in which the sleeve 40 is perfectly cylindrical and the slot 6 is closed by airtight.
  • a substance bacteriostatic substance By combining such a bacteriostatic substance with the arched form described above, we get the advantage that this substance will not be delivered to the user when actuation of the pump, since almost all of the product remaining at this location will have been removed during the previous closure of the closure element.
  • the shutter element itself can also be modified without departing from the scope of the invention.
  • its slit-like opening could be replaced by a very small hole capable of enlarging enough to allow the passage of a thin tube, especially for the distribution of droplets.
  • an ejection nozzle element comprising a swirl chamber to create the spraying is not necessary.
  • the sleeve deformable hollow cylindrical closure element could be replaced by a simple material disc elastomer for less restrictive applications. So, for example in the case of an application ophthalmic, the filling element could be produced in the form of such a disc having a hole.
  • This hole is closed in the closed position and closes sealingly the dispensing orifice of a tube of distribution.
  • said device distribution tube deforms said disc to open said hole, allowing said tube to pass through said hole for delivering a drop of product.
  • the tube is returned to its initial position and the hole in the disc closes automatically.
