This device comprises a body 1 forming a reservoir 11 and a head 2 composed of two elements 4, 5 which are aligned and which can move relatively, substantially axially, under the effect of forces F resulting from a manual pressure exerted laterally against and between the elements 4, 5 in a direction substantially perpendicular to their axis of alignment X-X'. This device allows in particular the delivery of liquid, pasty, powdery or aerosol products, in particular for cosmetic use, in order to apply them to any components.

Description

 The present invention essentially has for its object a device allowing the automatic delivery of any product, such as for example a liquid, an aerosol, a powder, a paste or the like, intended for any use or any application, in particular cosmetic, or allowing still the automatic delivery of any object for any use including graphics and which can be a utility object or even a tool such as for example a blade or a punch.

 There are already known automatic product delivery devices, which generally consist of a body containing the product and on which is mounted a head capable of delivering said product.

 The product can be delivered by manual pressure exerted on a push button located on the head or on the body opposite the head.

 It often happens that in the long run, the push button deteriorates or even detaches from the head, so that the delivery or distribution of the product can no longer be done, which, as we understand, constitutes a loss disadvantageous. In addition, in this type of device, the product delivery mechanism controlled by the push button is generally complicated and is therefore not of excellent reliability.

 Also, the present invention aims to remedy these drawbacks by proposing an automatic product delivery device forming a compact assembly, requiring no additional manipulation and other than manual pressure to deliver the product, and constituting a simple and reliable assembly. presenting no risk of deterioration, even after long use.

 To this end, the subject of the invention is a device for automatically delivering a product or any object and of the type comprising a body and a head capable of delivering said product or object under the effect of manual pressure. , characterized in that the tette consists of at least two aligned and relatively displaceable elements substantially axially under the effect of pressure forces exerted laterally against and between these two elements in a direction substantially perpendicular to their axis of alignment.

 It is therefore understood that the spacing of the two elements of the head under the effect of a digital and lateral pressure between these two elements will be sufficient to obtain the delivery of the product, which can be stopped by simply releasing the pressure.

 According to another characteristic of this device, the opposite faces of the two above-mentioned aligned elements form, in each axial plane, a re-entrant angle open towards the outside to allow the action of the aforementioned lateral pressure forces.

 It will be specified here that at least one of the two opposite faces of the two elements of the head may include sections of planar or curved shape, which can facilitate the pressure and therefore delivery operation.

 These sections may be three in number or a multiple of three.

 According to yet another characteristic of the invention, one of the two elements of the head, namely the outermost element, is integral with a tube opening into the body of the device and through which passes a rod, one end or first end cooperates with or passes through an orifice of said outermost element of the tette to allow delivery of the product or object.

 According to yet another characteristic of this device, the other element of the head is fixed to the body and has a bore in which the aforementioned tube can slide in leaktight manner, constantly stressed in the retracted position in the body by a spring or the like arranged between said tube and said other element, while the other or second end of the rod is integral with the body which forms a reservoir.

 According to another embodiment of this device, the other aforementioned element of the head actually consists of two elements, one of which forms a stirrup to which the second end of the rod is fixed and in which also slides the aforementioned tube.

 According to yet another embodiment, the body of the device consists of a threaded end piece which is adaptable to any container, in which the aforementioned tube slides in leaktight manner, and which is connected to the other element of the tette in which also slides in leaktight manner said tube constantly stressed in the retracted position in the end piece by a spring or the like arranged between the tube and said other element, while the other or second end of the rod is integral with a perforated disc retained in said tip.

 According to another embodiment of this invention, the body is constituted by the other element of the head and forms a monobloc threaded end piece adaptable to any container and comprising a bore in which the aforementioned tube can slide in leaktight manner when requested by a spring arranged between said tube and a shoulder in the bore, while the second end of the rod is integral with a perforated disc retained in said nozzle.

 The present invention relates to yet another embodiment in which the other element of the head is slidably mounted on the reservoir body, while the second end of the rod is integral with a member mounted to slide in leaktight manner through 'a partition in the body and connected to said other element which, under the effect of the aforementioned lateral pressure forces, allows the displacement of the rod relative to the aforementioned tube mounted fixed on the body, and this against the force a return spring arranged between said partition and said other element.

 According to yet another embodiment, the other element of the head is mounted movable and / or sliding on the body to which the second end of the rod is fixed, while between the aforementioned tube, integral with the body, and said rod , is interposed a hollow rod provided with bars or the like which pass through openings made in the tube and are integral with said other element which, under the action of the aforementioned lateral pressure forces, allows the displacement of the hollow rod relative to the tube and to the rod cited first, against the force of a return spring arranged between the ends of the tube and of the hollow rod.

 According to yet another embodiment, the other element of the head is mounted mobile and / or sliding on the body, while between the aforementioned tube and the aforementioned rod is interposed a hollow rod provided with bars or the like which pass through slots in the tube, which bars are integral with said other element which, under the action of the aforementioned lateral pressure forces, allows the displacement of the hollow rod relative to the tube against the force of a return spring arranged between said other element and said body to which the tube is integral, while means are associated with the hollow rod for moving the rod housed inside this hollow rod as well as at least one shutter for closing the outermost element of the head.

 The aforementioned means consist of a rack provided at each end of the hollow and meshing rod, one with at least one pinion meshing itself with the second end of the rod, and the other with a toothed sector belonging to the aforementioned component and pivotally mounted on the outermost element of the head.

 The aforementioned rod can here constitute a utility object or a tool.

 According to another characteristic of this invention, the first end of the rod may be provided with a tip capable of passing through the orifice forming a seat in the outermost element of the text which optionally includes a brush-applicator.

 The device of this invention can also be provided with a plug with internal ribs cooperating with the outermost element of the whole to facilitate its positioning.

 According to yet another characteristic of the invention, a flexible sleeve can advantageously be arranged between the two elements of the head, while a ring or the like, possibly integral with the internal wall of said sleeve, is interposed between these two elements.

 Thus, the spacing of the two elements of the head will be produced by exerting lateral pressure forces on the sleeve, and this spacing will be facilitated by the ring housed in the space provided between the sleeve and the two elements.

 According to yet another embodiment, in accordance with the invention, one of the two elements of the head, namely the outermost element, is mounted mobile and / or sliding on the body to which the other element is attached, and is provided with bars or the like which pass through lights made in the body and which carry an object such as a tool constantly stressed by a spring in the retracted position in said body and capable of projecting from the body through an orifice provided in the one end of this body.

 It will be specified here that the aforementioned orifice is closable by a flap or the like provided with an arm mounted articulated on the one hand on the body and on the other hand on the bars.

 According to yet another embodiment in accordance with the principles of this invention, the two elements of the head are mounted around a tube and inside a casing in which is slidably mounted the reservoir body connected to said tube, which envelope has on its wall a push button which, under the action of pressure forces exerted laterally actuates at least one of the two elements by means of at least one blade, so as to control the relative movement of the tube and d 'an applicator element housed in said tube.

 The aforementioned blade or blades have, according to an exemplary embodiment, the shape of a U and are mounted in pivoting support on the aforementioned elements and on the bottom of the push button.

 One of the two elements of the head, namely the outermost element, can be fixed on the product delivery tube, while the other element can be slidably mounted on said tube and be integral with the applicator element. which is constantly stressed by a spring in the stop position against the end of the tube.

However, other characteristics and advantages of the invention will appear better in the detailed description which follows and which refers to the appended drawings, given solely by way of example, and in which
- Figures 1, 2, 4, 5, 6, 7, 8 and 9 respectively illustrate and schematically in axial section various embodiments of a device according to this invention

- Figure 12 is an axial sectional view of yet another embodiment of the device according to this invention and operating by push button; and
FIG. 13 is a front view of a blade fitted to the embodiment of FIG. 12.

 Referring to all these figures, it can be seen that an automatic delivery device in accordance with the principles of the invention essentially comprises a body 1 and a head 2 possibly protected by a plug 3 and consisting of at least two aligned elements, consisting of element 4 which is the outermost and another element identified in 5.

 The two elements 4 and 5, according to an essential principle of this invention, are relatively displaceable substantially axially under the effect of pressure forces exerted laterally and manually, as shown by the arrows F, against and between these two elements, in a direction which is substantially perpendicular to their alignment axis XX ′.

 As can be seen in FIGS. 1 to 9, the facing faces 4a and 5a of the two aligned elements 4 and 5 form a re-entrant angle open towards the outside, and this so as to allow easy lateral insertion of the fingers between these two elements and therefore their spacing to allow the delivery of the product.

 To further improve this insertion of the fingers causing the spacing of the elements 4 and 5, at least one of the two elements 4, 5, such as for example the outermost element 4 may have on its face 4a opposite the face 5a of the other element 5 of planar or curved sections, as can be seen in FIG. 5.

 The number of these panels can be arbitrary, and it is possible, for example, to adopt a number of three panels or a multiple of three.

 The outermost element 4 is integral with the end 6a of a tube 6 through which passes a rod 7 having a first end 8 which can either cooperate with an orifice 9 formed in the axis of the tube 6, through the outermost element 4, (Figures 1, 2, 4, 5, 6 and 9), or pass through this orifice 9 (Figures 7 and 8) to allow the delivery of the product or object, as is will explain further about the operation of the various embodiments according to this invention and the description of which will be made now.

 According to the embodiment visible in FIG. 1, the element 5 of the head 2 is screwed, clipped or the like as seen in 10, on the body 1 which forms a reservoir 11.

 This element 5 has an axial bore 12 in which the tube 6 can slide in leaktight manner, thanks to seals 13 carried by the element 5.

 The tube B is constantly stressed in the retracted position in the body 1 by a return means such as a spring 14 rises between the free end 6b of the tube 6 and said element 5.

 The second end 15 of the rod 7 is, for its part, fixed to the bottom of the body or reservoir 11, as can be seen in FIG. 1.

 All the elements which come as described may be made of any material, such as synthetic.

 The operation of the device of Figure 1 is immediately inferred from the above description.

 The device is shown in the figure in the non-active position, that is to say that the first end 8 of the rod 7 is supported on the orifice 9 forming a seat formed in the element 4, which can have the shape of a flattened sphere or any other shape making it possible to form an open angle between its face 4a and the face 5a of the element 5.

 To use the device, simply remove the plug 3 and manually exert a force according to the arrows F, which will cause the separation of the element 4 from the element 5, against the force of the return spring 14, so that the first end 8 of the rod 7 will release the orifice 9, and the product contained in the reservoir 11 may therefore exit through this orifice.

 To obtain the closure of the orifice 9, it will suffice simply to release the lateral pressure along F, and the spring 14 acting on the tube 6 will cause the element 4 to be withdrawn and therefore the orifice 9 to be closed by the end 8 of the fixed rod 7.

 It will also be observed here that the end 8 of the rod 7 may include a point 16 capable of passing through the orifice 9 when it is closed, which advantageously avoids the fouling of this orifice by the product. Also, the element 4 can be provided, at the level of the orifice 9, with an applicator brush 17. These arrangements are also found together or separately in the variants of FIGS. 2, 4, 5, 6, 7 and 9.

 We could perfectly, without departing from the scope of the invention, do without the tip 16 and the applicator brush 17, and simply use for the end 8 of the rod 7 and the seat of the orifice 9 cooperating surfaces and complementary of any and appropriate geometry.

 18 has been shown in Figure I, raised portions provided on the periphery of the rod 7, and may also be provided on the inner periphery of the tube 6 to facilitate the flow of the product.

 Finally, it will be noted that the plug 3 has internal ribs 19 which, in the mounted position of the plug, cooperate with the element 4 to prevent any untimely opening of the orifice 9 which will therefore always remain applied against the end 8 of the rod 7 so as to ensure a good seal vis-à-vis the product contained in the reservoir 11. Such ribs 19 are also found on the plugs 3 fitted to the variants of FIGS. 2 and 4.

 According to the embodiment visible in FIG. 2, the element 5 of the head 2 actually consists of two elements integral with one another and one of which forms a stirrup part clearly visible in FIG. 3.

 To this stirrup-shaped part is fixed by screwing, for example the second end 15 of the rod 7.

 The part 20 includes, like the element 5, a seal 21, so that the tube 6 is guided and slides in leaktight manner in the bore 26 formed by the part 20 and the element 5.

 The tube 6 here comprises a flange 22 on which the end of a spring 23 bears, the other end of which bears on the element 5, so that, as in the embodiment of FIG. 1, the tube 6 is constantly stressed in the retracted position in the body 1 forming the reservoir 11 capable of containing any product.

 The operation of this variant is exactly the same as that described above, and will therefore not be described here again.

 It will simply be said here that the spring 23 is advantageously sheltered from the product, and that the stirrup-shaped part 20 allows the rod 7 to be maintained, which facilitates the production of the reservoir 11, as well as the filling and the 'assembly.

 In this regard, it will also be observed that the stirrup-shaped part 20 is, according to a preferred embodiment, screwed onto the body 1, as seen in 24, while the element 5 may have a thread 25 on which is screwed the plug 3, as was the case in the embodiment of FIG. 1.

 In the embodiment visible in Figure 4, we see that the body 1 is here constituted by a threaded end 40 which is adaptable, by screwing for example, on any container, so that the assembly shown in this figure constitutes in some produces a dispensing head for the product contained in any container or bottle.

 The second end 15 of the rod 7 passing through the tube 6 is here secured to a perforated disc 41 retained between a shoulder 42 and the thread of the end piece 40.

 This end piece 40, as can be seen in FIG. 4, is connected to one 5 of the two elements 4, 5 forming the head 2 and has a bore 43 allowing the guide and the sealed sliding of the tube 6, and this thanks to to a seal 44 carried by the end piece, just as a seal 45 is carried by the element 5 in which the tube 6 also slides.

 As in the embodiment of FIG. 2, the tube 6 includes a flange 46 on which the end of a compression spring 47 abuts, the other end of which bears on the element 5.

 In the rest position, it is therefore understood that the tube 6 and the outermost element 4 of the head 2 are in the retracted position, and the operation of the assembly is the same as that described with regard to the variants illustrated by the figures. 1 and 2.

 The end piece 1 is screwed onto a bottle, then the stopper 3 is removed and by applying lateral pressure along the arrows F, the element 4 will move away from the element 5, which will release the orifice 9 from the end 8 of the rod 7 and will therefore allow the distribution of the product contained in the bottle.

 The assembly shown in Figure 4 therefore constitutes an applicator cap which can be mounted on any container or bottle.

 The embodiment of FIG. 5 also illustrates a device with threaded end connectable to a container, as in FIG. 4, but which is of a very simplified design.

 The body 1 here simply constitutes the other element 5 of the tette 2 and forms a monobloc threaded end piece 50 comprising a bore 51 in which the tube 6 can be guided and slide in leaktight manner, thanks to one or more seals such 52. A spring 53 is interposed between the free and flared end 54 of the tube 6 and constantly urges the said tube in the retracted position in the end piece 50.

 As in the previous embodiment, the second end 15 of the rod 7 is integral with a perforated disc 56 retained in the threaded recess of the end piece 50. An annular shoulder of the end piece 50 has been shown at 55 and against which is retained the perforated disc 54 secured to the rod 7.

 The operation of the assembly which has just been described is exactly the same as that of the variant shown in FIG. 4, with the only difference that the flared end 54 of the tube 6 here forms a second valve capable of closing the tube 6 thanks to a conical part on the second end 15 of the rod 7, the first valve being constituted by the orifice 9 and the end 8 of the rod 7.

 In the embodiment shown in FIG. 6, the element 5 of the head 2 is mounted movable and / or sliding on the body 1 forming a reservoir 11.

 The body 1 is extended by an element 60 forming a transverse partition 61 with which the tube 6 is itself fixed by its end 6a on the outermost element 4 of the head 2. This element 60 also forms an annular extension 62 delimiting a chamber in which the element 5 can slide.

 On this element 5 is fixed, as can be seen at 63 a U-shaped member 64 which can slide through the partition 61 and to which the end 15 of the rod 7 is connected.

 The member 64 slides in leaktight fashion in the partition 51 by means of seals 65 provided in said partition.

 The operation is as follows.

 The device is shown in Figure 6 in the rest position, that is to say closed as was the case for the embodiments of Figures 1, 2 and 4, while the device of Figure 5 is illustrated in position "open", that is to say delivery of the product.

 A lateral pressure force is exerted according to the arrows F, and here it is not the outermost element 4 of the head 2 which departs from the element 5, but it is the opposite, namely that the element 5 will move in the annular extension 62 while driving the member 64 and the rod 7 which is associated with it, so that the end 8 of the said rod will disengage from the orifice 9 of the element 4 for allow the distribution of the product contained in the tank 11.

 By releasing the pressure of the fingers between the elements 4 and 5, the reverse movement will occur, that is to say that the movable element 5 will approach the element 4, which will cause the closure of the orifice 9 by the end 8 of the rod 7. This closing will be done automatically, as soon as the pressure is released, by the spring 66 interposed between the partition 61 and the movable element 5.

 This device, like the previous ones, can be used for the delivery of a liquid or semi-liquid product.

 By cons, the device shown in Figure 7 can be used particularly for the delivery of a powdery material, or even to allow the implementation of any instrument.

 Here, as in the embodiment of FIG. 6, the element 5 of the head 2 is mounted movable and / or sliding on the body 1 to which the second end 15 of the central rod 7 is fixed and which forms a reservoir It can contain any powder.

 Between the tube 6 secured to the reservoir 11, as can be seen at 70, and the rod 7, a hollow rod 71 is interposed through which the rod 7 passes and which is provided with bars or the like 72.

 These bars 72 pass through slots 73 made in the tube 6 and are integral with the element 5.

 The end 8 of the rod 7 here forms, for example, a small ball capable of closing off or not the open end in the form of a seat 71a, of the hollow rod 71.

 Between the other end 71b of the hollow rod 71 and the end 6b of the tube 6 opening into the reservoir 11, is arranged a spring 74 which permanently biases the end or seat 71a of the hollow rod 71 against the ball 8 for thus ensuring the obturation of said hollow rod.

 As in the embodiment of the previous figure 6, it is the element 5 which is movable and moves away from the element 4 of the head 2, under the effect of manual pressure between these two elements following the arrows F.

 But here, the element 5 will drive the hollow rod 71 through the bars 72, which can obviously struggle in the slots 73 of the tube 6. In other words, a space will be cleared between the end or seat 71a of the hollow rod 71, and the ball 8 so that the powder from the reservoir 1 can be delivered, it being understood that the applicator brush 17 secured to the element 4, can facilitate the application of the powder to such or such part of the body for example.

 If the pressure is released along F, the movable element 5 of the head 2 will approach the element 4 under the effect of the compression spring 74, which will seal the end or seat 71a of the hollow rod 71 .

 It will be observed here that the end or ball 8 of the rod 7 could constitute any instrument or tool whose release, allowing its implementation, could be ensured, as described above, by pressing according to the arrows F, which would allow somehow a projection of the instrument from the hollow rod or sheath 71.

 In the embodiment illustrated in FIG. 8, the element 5 of the head 2 is mounted movable and sliding on the body 1, as was the case in the variants of FIGS. 6 and 7.

 Similarly, as in the variant of FIG. 7, between the tube 6 and the rod 7, is interposed a hollow rod 80 provided with bars or the like 81 which pass through slots 82 formed in the tube 6. These bars 81 are integral with the movable element 5 so that, under the effect of a lateral pressure according to the arrows F, the hollow rod 80 can move relative to the tube 6 and to the rod 7, against the force of a return spring 83 arranged between the element 5 and the body 1 of which the tube 6 is integral.

 But, in this embodiment, the rod 7, the first end 8 of which can constitute any tool, such as a brush, a tracing, blunt or similar tool, can move in one direction or the other using the means described below.

 At one 80a of its ends opening into the body 1, the hollow rod 80 comprises a rack 84 meshing with pinions 85 which in turn mesh with the end 15 of rod 7. The pinions 85 are pivotally mounted on the body 1 by any appropriate means.

 At the other end 8Ob of the hollow rod 80 is provided another rack 86 meshing with a toothed sector 87 belonging to a flap 88 for closing the element 4 of the head 2. This flap 88 is pivotally mounted on the element 4 by any appropriate means, as shown diagrammatically in 89.

 The shutter 88 can close at least one orifice 90 formed in the element 4 of the head 2, but the operation will be explained in the following.

 By lateral pressure with the fingers along arrow F, the element 5 will drive the hollow rod 80 by its bars 81 in the direction of the body 1, so that the pinions 85 will drive the rod or tool 7 in the direction of the element 4, while, simultaneously, the flap 88, which can constitute for example two half-shells, will open. It follows that the tool or instrument (not shown) at the end 8 of the rod 7 will be released and can be used.

 If the manual pressure is released (opposite direction of the arrows F), the element 5 will be returned by the spring 83 towards the element 4, which will cause the hollow rod 80 in the opposite direction to that described above. In other words, the rod 7 with its tool will retract in the direction of the body 1, while, simultaneously, the flap 88 will close the opening 90 in the element 4, so that, ultimately, the tool carrying the rod will automatically be in storage or protected position.

 The embodiment visible in FIG. 9 corresponds substantially to that shown in FIG. 2.

 This means that the element 5 is actually made up of two parts, one of which 90 forms a sort of stirrup to which the end 15 of the rod 7 is fixed.

 But here, a flexible membrane 91 is also provided, fixed between the tube 6 and the body 1 forming a reservoir, so that a perfect tight connection is thus obtained between the interior of the reservoir I and the tube 6.

 Referring to Figure 10, we see at 92 a flexible sleeve which is arranged around the two elements 4 and 5 of the head 2. A ring or the like 93 is interposed in the space between the two elements 4, 5 and the sleeve 92. This ring 93 can constitute a flexible ring secured to the internal wall of the sleeve 92. In place of the ring 93, it is perfectly possible, without departing from the scope of the invention, to use balls housed in the space between the two elements 4, 5 and the internal wall of the flexible sleeve 92.

 Such an arrangement can be applied to all the embodiments described above and has the advantage of facilitating the spacing of the elements 4 and 5, since the pressure forces F exerted laterally on the flexible sleeve 92 will act on the ring or ring 93 to provide a sort of wedge effect between the elements 4 and 5 of the head 2.

 Of course, when the ring 93 is associated with the sleeve 92, these two elements can constitute a single piece obtained by molding.

 In the embodiment of FIG. 11, the outermost element 4 of the head 2 is slidably mounted on the body 1 of which the element 5 is integral.

 The external element 4 is provided with bars or the like 94 which pass through openings 95 formed in the wall of the body 1 and which carry an object such as for example a cutting or other tool 96.

 This tool 96 is constantly stressed by a spring 97 in the retracted position in the body 1, as can be seen in the figure. The tool 96 can obviously, by its active end 96a, protrude from the body 1 through an orifice 98 provided at one of the ends of said body.

 The orifice 98 is closable by a shutter or the like 99 which is extended by an arm 100 mounted articulated on the one hand at 101 on the body 1, and on the other hand at 102 on the bars 94 transversely integral with the tool 96 .

 It is therefore understood that in the rest position, the tool 96 is in the retracted position in the body 1 and that the orifice 98 is closed by the flap 99.

 By exerting lateral pressure forces F the element 4 moves to the right of FIG. 11, which will cause the exit of the active end 96a of the tool 96 through the orifice 98, it being understood that, simultaneously, shutter 99 will open. By releasing the pressure between the two elements 4 and 5, the device will resume the position visible in FIG. 11. This means that the tool 96 will retract in the body 1 and that, simultaneously, the flap 99 will close the orifice 98.

 The embodiment of FIG. 11 constitutes a somewhat simplified variant compared to that of FIG. 8.

 Reference will now be made to FIG. 12 to describe another embodiment of the device according to this invention.

 Here, the two elements 4 and 5 of the head 2 are mounted around a tube 103 and inside an envelope 104. The tube 103 is connected to the body 1 forming a product reservoir and mounted to slide in the envelope 104.

 This envelope 104 has on its wall a push button 105 which, under the action of a pressure force F exerted laterally, actuates the two elements 4, 5 by means of two blades 106a and 106b respectively, so as to control the relative movement of the tube 103 and of a rod-shaped applicator element 107 housed in the tube 103 and the end 8 of which forms a valve and has a brush passing through an orifice 9 at the end of the tube 103 .

 As best seen in Figure 13, each blade 106 has, in front view, the shape of a U so, in the mounting position, to allow passage in particular to the tube 103, but one could perfectly, without going out within the scope of the invention, imagine other shapes for the blades 106.

 Returning to FIG. 12, it can be seen that the blades 106 are mounted in pivoting support on the underside 105a of the push-button 105 and on the elements 4 and 5, as seen in 4a and 5a.

 More specifically, the blade 106a is supported on the element 5 which is slidably mounted on the tube 103 and of which is attached the applicator element forming a rod 107. This applicator element is constantly stressed by a spring 108 in the position for exiting the brush, that is to say, in the support position of the end 8 on the orifice 9 formed in the end 103a of the tube 103.

 As for the blade 106b, it bears on the outermost element 4 of the head 2, which element 4 is, according to the embodiment shown, secured to the tube 103 by gluing, welding or the like, as seen in 103b.

 The operation of the device which has just been described will be briefly explained below.

 In the rest position, that is to say the position visible in FIG. 12, the orifice 9 is closed so that the product contained in the reservoir body 1 will not escape.

 When the brush at the end 8 no longer contains any product, a lateral pressure is then exerted on the push-button 105, which, as is understood, will cause a relative displacement of the rod of the applicator element 107 relative to to the tube 103, so that the brush can be recharged with product, it being understood that this relative movement will be against the force of the spring 108. By releasing the push-button 105, the various elements of the apparatus will resume the position visible in Figure 12, that is to say that the device will allow product applications using the brush.

 One could perfectly use a single blade such as 106, and not two as shown in FIG. 12, this single blade being either the blade 106b or the blade 106a.

 If only the blade 106b is used, the tube 103, by pressing the push button 105 will advance relative to the rod of the applicator element 107 to release the orifice 9, it being understood that, in this case, the element 5 of the head 2 must be integral with the casing 104.

 If the blade 106a is used alone, the element 5 will then of course be slidably mounted on the tube 103, and the equipment constituted by the body 1 and this tube 103 may possibly be made integral with the casing 104.

 Of course, the invention is in no way limited to the embodiments described and illustrated which have been given only by way of example.

 This is how the shape and material of the parts involved in the various embodiments can be arbitrary. It is the same with regard to the particular arrangement of the valve formed between the end 8 and the orifice 9, this being a function of the applications envisaged for the device and also of the product to be delivered.

 This means that the invention includes all the technical equivalents of the means described as well as their combinations, if these are carried out according to the spirit.
