Definitions

• the present invention relates to a fluid, liquid or pulverulent product dispenser comprising a reservoir defining an actuating wall which can be moved or deformed to vary the volume of the reservoir and thus expel its content from the reservoir.
• This type of dispenser is further provided with an outlet or dispensing orifice which is connected to the reservoir so that by actuation of the reservoir, part of its contents is dispensed through the outlet orifice.
• the tank contains fluid, but it can also contain gas, for example air.
• gas for example air.
• actuating the wall of the reservoir a mixture of air and fluid is expelled through the outlet orifice.
• This type of distributor finds an application in the field of perfumery, cosmetics or even pharmacy.
• Document FR 2 791 645 describes a dispenser of this type comprising two flexible deformable sheets welded together on their periphery so as to create an internal volume defining a reservoir of fluid product.
• a distribution piece is advantageously fixed by welding between the two sheets.
• This part advantageously defines a dispensing orifice and at the same time serves as a support part for an element of porous material capable of being imbibed or impregnated with liquid or pulverulent fluid product.
• the reservoir contains a spring making it possible to bring the two sheets back into a rest configuration defining the maximum volume of the reservoir. This spring allows each actuation to return the reservoir to its rest position.
• the reservoir contains a small quantity of fluid and a greater quantity of gas, for example air. Thus, each actuation, a mixture of air and fluid is forced through the dispensing orifice.
• the present invention aims to remedy this drawback of the prior art by defining a fluid dispenser which is not likely to leak even in the absence of a plug or a member for closing the orifice of distribution.
• a fluid dispenser comprising a gas reservoir defining an actuation wall for varying the volume of the reservoir and thus expelling the gas from said reservoir, at least one fluid reservoir defining a actuating wall to vary the volume of the reservoir and thus expel the fluid from said reservoir, at least one outlet orifice common to the gas reservoir and to a fluid reservoir a gas supply conduit which connects the reservoir gas at the common outlet, at least one fluid supply channel which connects a fluid reservoir to the common outlet.
• the dispenser comprises several fluid product tanks, so that it is for example possible to size the fluid product tank so that it is sufficient for only one or two actuation (s) of the wall of the gas tank.
• this gas tank never contains any fluid.
• the conduit joins the channel at the outlet orifice. Thus, it is almost impossible for fluid to enter the gas tank through the supply duct.
• the outlet orifice is formed at the level of an outlet chamber into which the conduit and the channel open.
• the chamber contains a piece of porous material capable of being impregnated with a fluid product.
• the piece of porous material is disposed between the duct and the channel.
• the piece of porous material fulfills a buffer function between the conduit and the channel (s) by preventing the fluid product from propagating in the supply conduit of the gas tank.
• the piece of porous material acts as a porous plug. There is thus a complete separation between the fluid product and the gas, practically up to the level of the outlet orifice, and more generally up to the level of the outlet chamber.
• the channel comprises initial sealing means capable of cutting off the communication between the reservoir of fluid product and the outlet through the channel.
• the initial closure means are capable of opening by actuating the actuation wall of the fluid reservoir.
• the reservoirs, the conduit and said at least one channel are formed between two sheets locally fixed together.
• a sheet is substantially deformable and forms the actuating walls of the reservoirs.
• the sheet is a profiled shell, advantageously thermoformed.
• the other sheet can be substantially flat.
• the dispenser can be produced only from two elements, namely the two sheets. In the case where a piece of porous material is incorporated, the number of pieces of the distributor then amounts to three.
• the dispenser comprises at least two fluid product reservoirs (13) containing different fluid products intended to be mixed advantageously extemporaneously at the outlet orifice .
• FIG. 1 is a perspective view from above and from the side of a fluid dispenser according to a first embodiment of the invention
• Figure 2 is a longitudinal vertical cross-sectional view through the dispenser of Figure 1
• Figure 3 is a perspective view from above of a dispenser according to a second embodiment of the invention.
• the dispenser comprises three constituent elements, namely an upper sheet 1, a lower sheet 2, and a piece of porous material 142.
• the piece of porous material 142 is optional, and in certain cases, it can be omitted, so that the dispenser is made up only of two constituent elements, namely the two sheets 1 and 2.
• sheet used here should be understood broadly as any element having a relatively reduced wall thickness in one dimension, while in the other dimensions, the element can be extended. Of more, this element may have a constant or variable reduced wall thickness.
• the element can be very flexible, relatively flexible, relatively rigid or very rigid. It can also be flexible or deformable, locally or entirely. This element can be perfectly flat, or have one or more protruding profiles in relief.
• one sheet or both sheets can be in the form of flexible or rigid plates advantageously having one or more raised profiles.
• the term sheet here includes the term plate, substrate, support, film, shell, etc.
• the sheet 1 is in the form of a profiled shell, advantageously thermoformed, which comprises a flat main zone 11 which extends over the entire periphery of the sheet.
• the sheet 1 forms a main dome 120 which projects from the flat area 11, as can be clearly seen in FIG. 2.
• the sheet or shell 1 also forms a raised rib 150 which extends from the dome 120 to a raised promontory 140 pierced with an outlet orifice 141.
• the raised rib 150 which extends from the dome 120 to a raised promontory 140 pierced with an outlet orifice 141.
• the main rib 150, the promontory 140 and the secondary ribs 160 can be flexible or non-deformable.
• the main dome 120 and the secondary domes 130 they are made in a deformable and advantageously elastically deformable manner, so that they can return after deformation to their initial convex shape as shown in FIG. 2.
• the curvature of the domes 120 and 130 can be more or less marked, that is to say curved or flattened and of any geometry, for example polygonal or ellipsoidal.
• the second lower sheet 2 it can be in the form of a flat, rigid substrate or a flexible opercular sheet, or even in the form of a flat or profiled shell.
• the lower sheet 2 is identical to the upper sheet 1, that is to say made in the form of a profiled shell.
• the upper sheet 1 is connected to the lower sheet 2 at the level of the flat area 11 which comes into contact with the lower sheet 2.
• the welding can be carried out on the periphery of the sheets 1 and 2, and preferably around the domes 120 and 130 and along the ribs 150 and 160 as well as around the promontory 140.
• the dome 120 thus defines according to the invention a gas reservoir 12
• the main rib 150 defines a supply duct 15
• the secondary domes 130 each define a reservoir of fluid product
• the secondary ribs 160 each define a fluid supply channel 16 and the promontory 140 defines a common outlet chamber
• the outlet chamber 14 at the level of which the outlet or distribution orifice 141 is defined communicates with the gas tank 12 through the supply duct 15.
• this same common outlet chamber 14 communicates with the fluid product reservoirs 13 through the fluid product supply channels 16. It can thus be noted that the gas supply conduit 15 does not join the channels of supply of fluid 16 only at the level of the common outlet chamber 14. Since this chamber 14 can be reduced so as to define only the zone situated below the outlet orifice 141, it can be said that the conduit 15 joins the channels 16 only at the level of the dispensing orifice 141.
• the common outlet chamber 14 can contain a piece of porous material 142 capable of being impregnated with a fluid, liquid or powdery product.
• This piece of porous material 142 is located in the immediate vicinity, and even in contact with the dispensing orifice 141.
• the conduit 15 can only communicate with a channel 160 by through this piece of porous material 142.
• it fulfills the function of a porous plug or plug which thus prevents any rise in the fluid product in the channel 15 which connects to the gas reservoir 12. This thus operates a complete separation between the fluid and the gas in this distributor: they only meet at the level of the distribution orifice 141 which can advantageously be provided with the piece of porous material 142.
• At least one of the channels, and preferably all of the channels are closed or blocked at one or more places along their length, so that the fluid reservoirs 13 are initially isolated from the outlet chamber 14, and therefore from the distribution orifice 141.
• This occlusion of the channels 160 can for example be produced in the form of a weak weld 161 between the sheets 1 and 2 at the level of the channels 16 , as can be seen in FIG. 2.
• This weak weld 161 has the function of breaking down or breaking when the pressure in the channel 16 is sufficient to detach the sheet 1 from the sheet 2 and thus reconstitute the channel 16 over all its length.
• the necessary pressure can, for example, be generated by pressing on the actuation wall formed by the secondary dome 130.
• the user After dispensing, the user releases his pressure on the main dome 120, which due to its elastic deformation memory returns to its rest position as shown in FIG. 2.
• the number of actuations necessary on the main dome 120 it is also possible to precisely determine the number of actuations necessary on the main dome 120 to empty the piece of porous material 142 of all or almost all of the fluid product coming from the chamber 13.
• the main dome 120 there is no more or almost no more fluid impregnated or soaked inside the piece of porous material 142. There is therefore no longer any risk of leakage through the outlet orifice 141.
• the main dome has a shape memory urging it towards its initial position. This is not compulsory in the case of secondary domes.
• FIG. 3 we see a second embodiment of a dispenser according to the invention.
• This distributor can also be made from two sheets or plates locally welded together.
• the distributor forms a gas reservoir 12 defining an actuating dome 120, and two fluid product reservoirs 13 also each provided with an actuating dome 130.
• the reservoirs 12 and 13 are connected to a mixing 14 'in which is advantageously located a piece of porous material 142.
• the gas tank 12 communicates with this chamber 14 'via a conduit 15, while the fluid reservoirs 13 communicate with this same chamber 14' via channels 16.
• the channels 16 are provided with cut-off means 161 which can also be in the form of a weak weld 161, as in the previous embodiment.
• the two fluid product chambers 13 each contain a fluid of different nature intended to be mixed extemporaneously in the mixing chamber 14 '.
• the distributor further comprises a support and distribution piece 3 which can for example be made of molded injected plastic.
• This support piece 3 can define a support housing for the piece of porous material 142 as well as a fixing appendage located at the level of the promontory 140.
• the sheets or plates constituting the dispenser can for example be welded to the piece of support 3.
• the support piece 3 defines a tip 31 at the free end of which the dispensing orifice 141.
• the tip 31 can be a nasal tip.
• this dispenser is carried out as follows: The user begins by pressing on a dome 130 of one of the fluid product tanks 13 so as to break the weak weld 131 so that the fluid product contained under the dome can flow through the channel thus reconstituted to reach the level of the mixing chamber where advantageously is the piece of porous material 142. The user then proceeds symmetrically for the other reservoir of product fluid. Thus, the two fluid products of different nature can mix at the mixing chamber inside the piece of porous material. The user then just needs to press the actuating dome 120 of the gas tank 12 to expel gas through the conduit 15 into the piece of porous material 142.
• the dispenser 1a in FIG. 3 is more particularly suitable for medical or cosmological use.
• the invention there is a two-phase distributor, advantageously multi-dose, in which the separation between the fluid and the gas is complete and which suffers from no leakage defect. In addition, it can be declined in an inexpensive version usable as a sample.
