Description

The invention relates to a device for dispensing a dose of product

  fluid such as typically for a sample of perfume or cosmetic product, a method of producing this device and an installation for carrying out said method.

  It is known in the field of sample distribution, in particular from documents FR-A-2 836 128 or FR-A-2 796 368, dispensers consisting of a reservoir comprising at least one actuating wall and included in an envelope covering at least partially the reservoir.

  Among the sample dispensers by mail or press, disposable vaporizers such as that described in document FR-A-2 778 639 are described. This sample dispenser comprises a reservoir consisting of at least one wall of deformable actuation by application of a pressing force. With a very small thickness, this sample dispenser is described as being able to withstand high pressures.

  However, the disadvantage of the distributors described in the previous documents lies in the fact that the pressure force, during the distribution by press, is exerted on the walls of the device or on the thin sheets and is transmitted to the product, increasing the risk of bursting or leakage of the device.

  In order to avoid this problem, document FR-A-2 791 645 describes a dispenser comprising, in its reservoir, an elastic element. In fact, in this dispenser, the pressure force is exerted not on the liquid contained in the reservoir, but on the elastic element which is included therein. The walls of this dispenser consist of two sheets of complex film welded together at their periphery. The elastic element exerts a restoring force on these deformable walls as long as the closure element closes the dispensing orifice but also at each pressure. However, since the actuating walls of the device are sheets of complex film having a certain elasticity, the force exerted by the elastic element is likely to result in wear, an increase in the risk of tearing or degradation of the walls. actuation. In addition, the very inclusion of this part during the manufacture of the dispenser is in itself a drawback.

  The technical problem of the invention is to be able to avoid the above disadvantages while meeting certain requirements. Indeed, a sample dispenser to be distributed by mail or press must be extremely flat and resistant since it must withstand high pressures. In order to avoid any risk of leakage, the pressure force related to the mode of distribution of the sample must be exerted solely on the walls, without inclusion of elements in the tank likely to alter it. In addition, this device must be simple to manufacture. It must be feasible in large series and low cost since in general, the samples are not intended for sale and they are single-use can dispense a single dose. Finally, it must be simple, practical and effective to achieve its purpose of promoting the use of a product.

  For this purpose and according to a first aspect, the invention proposes a device for dispensing a dose of fluid product such as typically for a perfume or cosmetic product sample comprising: a reservoir containing the fluid product to be dispensed and comprising two facing actuating walls and a side wall extending between the actuating walls, said walls having overall rigidity; A dispensing orifice putting in fluid communication the interior and the exterior of the tank, said dispensing orifice being provided with means for spraying the fluid product; a removable shutter member for hermetically closing the dispensing orifice; Said device being in one of the following three states: - a compressed-closed original state in which the actuating walls are kept substantially parallel to each other with a minimum spacing, the shutter element By closing the dispensing orifice, in this state, the reservoir comprises the fluid dose; - An expanded-open state of use in which the dispensing orifice is open, the actuating walls having a maximum spacing, this state being obtained in the absence of compressive stress, especially after opening the orifice. distribution; and a compressed-open state of use of spray in which the actuating walls are brought closer to each other under the effect of a compressive stress exerted on at least one of the actuating walls. this state being later than the deployed-open state of use.

  This device further comprises elastic biasing means for biasing said device towards the deployed-open state the compressive bias, in the compressed-open state of use, against these means of compression. elastic bias, said elastic biasing means being located outside the tank or incorporated in the side wall.

  According to a first embodiment, the zone of attachment of the two assemblies 25 may form part of said lateral wall, this joining zone may furthermore be the free edge of the lateral wall.

  According to another embodiment, the zone of attachment of the two sets may be part of a flange transverse to said side wall.

  In a first variant, the second assembly is a second integrally actuated wall with said first shell and separated by a folding zone. The first and second unit structure thus formed, is made open flat and is folded, an assembly on the other to be secured.

  In a second variant, the second actuating wall is a structure distinct from said first shell. In the latter case, said second actuating wall has a relatively flat surface and at least sufficient for the formation of the reservoir by its peripheral attachment to said shell.

  In a third variant, the second set may be a second shell. These first and second shells can be either monoblock separated by a folding zone or separate structures.

  The dispenser according to the invention is provided with at least one orifice in fluid communication with said reservoir via a neck having a generally planar structure parallel to the plane formed by the reservoir and of a thickness substantially equal to that of the reservoir. when it is in its original compressed-closed state and parallel to the plane formed by the reservoir. This orifice may be a dispensing orifice or a filling orifice which will be closed after filling of the reservoir, the device possibly comprising both a dispensing orifice and a filling orifice or having only one orifice called dispensing orifice. /filling.

  According to the invention, said sealing means closing said dispensing orifice or said dispensing / filling orifice is a breakable structure or a peelable structure.

  The elastic biasing means according to the invention are either incorporated in at least a portion of said side wall or outside thereof. They comprise at least one fold line in the same general direction as the actuating walls.

  According to the invention, the device can be implemented alone or with support means such as a flexible sheet, rigid or semi-rigid and / or protective means such as thin walls and flexible secured (23) l one to the other in the vicinity of their periphery, said two thin and flexible solidarized walls (23) being constituted by two separate thin and flexible sheets or a folded thin and flexible sheet.

  According to a second aspect, the invention relates to a method of producing this device in the compressed-closed state and having an orifice called distribution / filling orifice for dispensing and filling the device comprising the following successive steps is carried out first. and second constituent assemblies of the reservoir, said two assemblies are joined so as to form said reservoir, the dispensing / filling orifice being then open and the reservoir empty, the reservoir is urged in the direction of compression, said reservoir is filled with the dispensing / filling orifice, the order of the filling and compression steps being indifferent, the dispensing / filling orifice is sealed so as to produce a filled and closed device in the compressed-closed state.

  According to one variant, the invention proposes a method for producing this device in the compressed-closed state and having a dispensing orifice and a filling orifice comprising the following successive steps: the first and second constituent assemblies of the reservoir are produced; these two assemblies are secured so as to form said reservoir, the filling orifice then being open, the dispensing orifice closed and the reservoir empty, the reservoir is urged in the direction of compression, the reservoir is filled with the filling orifice, the order of the filling and compression steps being indifferent, hermetically closing the filling orifice so as to produce a device filled and closed in the compressed-closed state.

  The dispensing device according to the invention consists of a reservoir 1 of two actuating walls 2 and a side wall 3. The fluid communication between the inside and the outside of the reservoir is effected by means of a neck 4 opening on a dispensing orifice 5. The shutter of the tank is made possible by a shutter element 6.

  The side wall 3 connects the two actuating walls 2. It is provided with resilient biasing means comprising a folding zone 7 allowing a rapprochement or removal of the actuating walls 2 and thereby a reduction in the internal volume of the reservoir. 1. This folding zone 7 may be in the side wall 3 or adjacent thereto outside the tank 1.

  According to a variant of the dispenser, the actuating walls 2 are parallel io (FIG. 1A), the side wall 3 linking the actuating walls 2 is therefore of equal width over the entire periphery of the tank 1. The folding zone 7a concerns the entire side wall 3 over the entire periphery of the tank 1 except at the anchor point of the neck 4 where the most central fold lines 8 are interrupted. These fold lines 8 are in the same general direction as the actuating walls 2 and have a bellows structure. The exercise of a compressive force F on the actuating walls 2 brings them closer together by folding the folding zone 7 of the lateral wall 3.

  According to another variant of the device, the dispenser has a pyramidal structure in which the actuating walls 2 are not parallel to each other and the fold lines 8 are not parallel to the actuating walls 2 (FIGS. B and 1C). . The planes formed by these fold lines 8 and the planes formed by the actuating walls 2 converge and intersect at a point 25 forming the top of the pyramid and located near the anchor point of the neck 4 on the wall 3. Due to this pyramidal structure, the side wall 3 connecting the non-parallel actuating walls 2 is of variable width.

  The folding zone 7b may, according to the invention, concern the entire side wall 3 except in a portion 3b of the side wall 3 supporting the neck 4 (Figure 1B). On this portion 3b of the side wall 3, the neck 4 pierces the entire width of the side wall 3 which becomes, at this point, almost nonexistent. The diameter of the neck 4 is in this variant, equal to the thickness of the tank 1 when the side wall 3 is folded to the maximum.

  The folding zone 7c may also be more central and occupy only part of the width of the side wall 3, the outer edges 3c having a relatively flat surface (Figure 1C). In this embodiment, the diameter of the neck 4 is less than or equal to the thickness of the folding zone 7c when the latter is folded to the maximum so that the reservoir 1 is as flat as possible when a compression force F is On the latter two pyramidal reservoir variants, the exercise of a compressive force on the actuating walls 2 brings the farthest edges 2a closer to the walls of the pyramidal reservoir. actuation 2 until the side wall is completely folded. This maneuver 15 allows a reduction in the internal volume of the tank 1. In this state, the two actuating walls 2 are relatively parallel so that the device is as flat as possible.

  According to the invention, the distributor is found in three states. An original state, i.e. the state in which the dispenser 1 is stored after the filling and sealing of the reservoir, the compressed-closed state in FIG. 2A. In this state, the tank has a minimum volume to have a distributor extremely flat structure that can be incorporated between two sheets pressed against each other and compressed such as the pages of a magazine of 25 magazines or books . The pressure force P exerted on the actuating walls 2 during the dispensing of the device is supported by the side wall 3 and in particular by the thickness of its folds. This thickness will determine the minimum volume of the tank 1 when it is compressed.

  The folding zone 7 exerts an elastic bias F1 which tends to move the actuating walls 2 away. When the user opens the dispenser, these elastic biasing means cause the actuating walls 2 to move apart and thus the reservoir to be deployed. 1. This state is called the open-open state shown in Figure 2B. i0

  When the user exerts on the actuating walls 2 a compression force F greater than the elastic biasing F1, it induces a bringing together of the two actuating walls 2 and thus a retraction of the volume of the reservoir 1 causing the expulsion of the product contained in the reservoir 1. When this force F is exerted on at least one of the actuating walls 2, the device is in a compressed-open state illustrated in Figure 2C.

  The reservoir is obtained from the joining of two sets E1 and E2. These two sets can be obtained by thermoforming, plastic injection or any other embodiment of plastic piece. According to one variant, these sets E1 and E2 are identical and are two shells 9 each comprising an actuating wall 2, a side wall 3 and an extension in a gutter 10 allowing, after joining the two shells, obtaining the neck 4 (Figure 3A). The edges 11 of each set are perfectly congruent so that their connection is completely hermetic and that the neck 4 is formed by the space left between said two sets E1 and E2 forming the tank 1 after their joining. According to one variant, these sets E1 and E2 are different, the first being a shell 9 and the second a second actuating wall 2b (FIG. 3B). The edge 11 of the shell 9 is parallel to the second actuating wall 2b so that once the actuating wall 2b has been folded over the shell 9, their joining is hermetic. The shell 9 comprises a first actuating wall 2c and a side wall 3 which extends towards the neck 4. In this embodiment, the neck 4 is located at the junction between the actuating wall 2b and said side wall 3.

  For each variant of the device, the two sets can be obtained in one piece by thermoforming, plastic injection or any other embodiment of plastic piece. This one-piece structure is made open flat so as to be folded at a fold zone 12, an assembly on the other to be secured.

  We will describe more particularly a one-piece structure composed of two different sets E1 and E2 (FIGS. 4A and 4B), this description is transposable to a one-piece structure composed of two identical sets E1 and E2. In this embodiment, the second actuating wall 2b has a general contour matching that of the shell 9. At the outer face, the shell 9 is composed of an actuating wall 2c relatively parallel to the second actuating wall 2b , a side wall 3 and a flange 15 (Figure 4A). The side wall 3 comprises a folding zone 7 surmounting a border 13. The flange 15 is transverse to the side wall 3 and parallel to the second actuating wall 2b. The inner face of the flange 15 constitutes the zone of attachment of the shell 9 with the second actuating wall 2b. The flange 15 comprises two projections, a projection 16 and a second projection corresponding to the neck 4 and originating on the edge 13.

  The neck 4 consists of two portions, an initial portion 4a, extension of the edge 13, and a final portion 4b which is partly adherent to the outer face of the flange 15 of the shell 9 and free. The free end of the final portion 4b of the neck 4 is connected to the shutter element 6. In this variant, the shutter element 6 is obtained during the production of the shell 9 with which it is monobloc . The shutter element 6 is breakable. Indeed, it is connected to the neck 4 which it closes by means of a zone of section 14 so that the rupture of this zone opens said dispensing orifice 5. The shutter element 6 is composed of a portion plane 6a facilitating gripping when opening the device.

  The initial portion 4a of the neck 4 adhering to the flange 15 corresponds to a channel 18 hollowed the inner face of this flange 15 (Figure 4B). The channel 18 connects the inside of the shell 9 to an orifice 19 located at the bottom of the channel 18. When the shell 9 is joined to the second actuating wall 2b, the channel 18 is closed off by the second wall. 2b actuation to form a channel for conveying the contents of the tank. This delivery channel crosses the neck 4 from one side to the other and opens at the dispensing orifice 5.

  The projection 16 at the outer face of the flange 15 on the lateral edge of the shell 9 corresponds to a gutter 17 at its inner face. The fastening of the shell 9 with the second actuating wall 2b allows, by closing the channel 17 the formation of a filling channel opening towards the outside of the tank at a filling orifice 17a.

  The inner face of the second actuating wall 2b has no particular structure, it can be flat or slightly concave.

  Once the second actuating wall 2b folded over the shell 9, the two sets are secured to form the device according to the invention shown in Figure 5A. In this variant and according to the invention, the dispensing orifice 5 is closed by the shutter member composed of a flat portion 6a which is manufactured in one piece with the shell 9. The filling of the tank 1 is then carried out by the filling orifice 17a formed by the joining of the two sets. So that the device has a small thickness during its distribution, a compression force F is exerted on the actuating walls 2 and the device is filled by the filling orifice 17a (Figure 5B). Once the reservoir 1 is full, the filling orifice is closed (FIG. 5C).

  According to another embodiment of the invention, the tank 1 consists of a shell 9 and a second actuating wall 2b independent of the shell 9 (Figure 6). The shell 9 has the same structure as before. The second actuating wall 2b may be a more or less rigid plasticized sheet, the surface of which may be very variable but must be sufficient to allow the formation of the tank 1 to be secured hermetically with the shell 9. The fastening of the second wall 2b and the hull 9 is performed on the inner face of the flange 15.

  According to the embodiment illustrated in FIG. 6, the filling of the device by a dose of fluid product d may take place before the joining of the two sets E1 and E2, in which case the dispensing orifice 5 is closed before filling the device; either via the single orifice of the tank 1 which in this case is called the dispensing / filling orifice 20 and which acts as both a filling orifice and a dispensing orifice. In this case, the dispensing / filling orifice 20 is closed after filling of the device. In the embodiment of FIG. 5, the filling is performed after joining, hence the existence of the filling orifice 17a.

  A compression force F is exerted on the actuating walls 2 of the tank 1. It can be exerted either before filling and in this case it is maintained during filling and closing of the tank 1. Either after the filling and, in this case, it is maintained during the closure of the tank 1 so that the device is made in a compressed-closed state. Closure means either the joining of the two sets E1 and E2, or the closing of the dispensing / filling orifice 20, or the closing of the filling orifice 17a when one of these events is the one which allows the closure of the tank 1 in its compressed-closed state.

  After filling, the installation of the spraying system 21 and that of the closure system 6 can be simultaneous or consecutive.

  In a first variant, the two installations are consecutive. Indeed, after filling the device (FIG. 7A), the spraying means 21 is installed (FIG. 7B) in the channel for conveying the neck 4 through the dispensing orifice 5 or the dispensing / filling orifice 20. FIG. The dispensing orifice 5 or the dispensing / filling orifice 20 may be closed by a peelable sealing member 22 as illustrated in FIG. 7C. Note that in the embodiment illustrated by FIGS. 7A and 7C, the shell 9 is secured to a second actuating wall 2b in which the said neck 4 is made. The surface of the second actuating wall 2b is more large than the periphery of the shell 9 to which it is secured.

  In a second variant, the two installations are simultaneous. Indeed, in this embodiment, the spraying system 21 is provided with irreversible fastening means 23 allowing a hermetic assembly following its insertion into the neck 4 by the dispensing orifice 5 or the dispensing / filling orifice 20 (Figure 8A). The irreversible fastening means 23 used may be snap-fastening or any other means permitting an immovable and hermetic fastening of the spraying system 21. The shut-off element 6 may be connected to the spraying system 21 so that the irreversible attachment of the Spraying system 21 simultaneously allows the closure of the dispensing orifice 5 or the dispensing / filling orifice 20. The shutter element 6 is in this embodiment preferably a shutter member with a breakable zone. section 14 and a flat portion 6a for a better grip of the closure member 6 (Figure 8B). In this embodiment, the device consists of a shell 9 and an actuating wall 2b. The shell 9 has a wide flange 15 whose contour corresponds to the surface of the second actuating wall 2b.

  The device according to the invention is intended to be distributed by the press, it has more, an advertising purpose. In this context, it can be included in protection means.

  For this embodiment, the device after joining the two sets E1 and E2, is included between two thin and flexible walls 23 secured to one another in the vicinity of their periphery at a securing zone 24 (FIG. 9A and FIG. 9B). The device can be included between a single folded thin and flexible sheet, and then secured at its edges allowing closure of the protection means by three welding strips. Or the device can be included between two separate thin and flexible sheets secured at their periphery for closing the protection means by four welding strips. The device can either be fixed between two thin and flexible walls 23 secured, or it can be free.

  The device maintained fixed between the thin and flexible walls 23, can be maintained by the neck 4 by a securing zone 24a (Figure 9A). These securing zones 24 determine two chambers, a chamber C1 containing the reservoir 1 and a chamber C2 in which the closure element 6 is held, the neck 4 passing through the securing zone 24a. This protection means consisting of at least one thin and flexible sheet secured at least partly on its periphery is provided with opening means 25. These opening means 25, according to a variant of the invention, are precut lines 25. These precut lines 25 are located at the height of the dispensing orifice 5 or the dispensing / filling orifice 20.

  Upon opening of said secured thin walls 23, either the shutter member 6 is made accessible to the user, if it is free in the CA chamber. Either the opening of the device is simultaneous with the opening of the thin walls 23 secured in the case where the closure member 6 is held fixed between the thin walls secured 23 In the latter case, the opening of said thin walls secured 23 causes the dispensing device to open.

  In the case of a free device between the interconnected thin walls 23 (FIG. 9B), the securing zones 24 delimit only one chamber and the opening of the secured solid walls 23 gives access to the device.

  In order to allow a better fixing of the device in the press during its distribution or to facilitate its fixing between two thin walls secured 23, it can be included in a support 26. One of the two sets E1 or E2 and more particularly a shell 9 is included in a support means 26, which can be a rigid sheet, semi-rigid or flexible. In the case of a device formed by two different sets E1 and E2 (FIG. 10), the second actuating wall 2b is secured either solely to the internal face of the flange 15 or to the internal face of the flange 15 and on the support 26. When the second actuating wall 2b is sufficiently wide to cover the entire surface of the support 26, it allows consolidation of the device.

  Once included in the support 26, the device can be introduced between two interconnected thin walls 23. This embodiment allows another method of fixing the device between the secured thin walls 23, the periphery of the support 26 being able to be at least partly included in FIG. the zone of attachment 24 of the two thin walls 23.

  This device may be filled with a dose of fluid product d either before the joining of the two assemblies, or after their joining in a similar manner to the device illustrated in FIG. 6.

  During filling before joining the two sets E1 and E2, the dispensing orifice 5 is provided with a spraying system and is closed before the joining of the two sets E1 and E2 (FIG. 11A). The shutter can be done by a peelable sealing element 22 or breakable 6, 6a. So that the device is as flat as possible, a compressive force F is exerted on the actuating wall 2c of the shell 9 before the shell 9 is filled. Then the two sets E1 and E2 are secured, the compression force F is maintained during the filling and sealing of the reservoir so that the device is made in a compressed-closed state.

  During filling after the joining of the two sets E1 and E2, a compressive force F is exerted on the actuating wall 2c of the device in order to reduce its thickness (FIG. 11B). The tank 1 is then filled with a dose of fluid product d through the dispensing / filling orifice 20.

  The dispensing / filling orifice 20 is provided with a spraying system and is closed off. The latter maneuvers may be simultaneous or consecutive as previously described. The compression force F is maintained during filling and sealing of the reservoir so that the device is made in a compressed-closed state.
