Description

Title of the invention: Dispenser for a fluid product and associated receptacle Technical field of the invention

[0001] The invention relates to a dispenser of a fluid product configured to be mounted reversibly on a reservoir of fluid product.

[0002] The invention also relates to a receptacle comprising such a dispenser.

[0003] The fluid product is of the type lotion, gel, perfume, serum or cream for example, used for cosmetic purposes or for pharmaceutical treatments. Technical background

[0004] Dispensing systems exist for use in receptacles, enabling the withdrawal and distribution of a fluid product. Typically, these dispensing systems comprise a piston that moves from a rest position to a withdrawal or dispensing position. This movement is generally achieved by means of a push button (or actuator) linked to the piston, which, when pressure is applied by a user, causes the piston to move and withdraw and / or dispense a dose of the fluid product.

[0005] Such systems are found, for example, in dropper-type receptacles where the dispensing and distribution of the product must be precise and in small doses. These systems replace conventional systems comprising a flexible bulb for aspirating and / or dispensing the product into a pipette housed in a reservoir containing the product. A first press aspirates the product and a second press dispenses it.

[0006] These systems also generally include a means of returning the piston and push button, which allows the piston and push button to automatically return to their rest position once the dose of fluid product has been drawn and / or dispensed. In other words, the piston returns to its rest position without user intervention, and consequently, the push button also returns to its rest position.

[0007] Typically, the return mechanism is a spring, in particular a helical spring. To ensure effective return of the piston and push button, especially in terms of longevity, the spring is generally metallic.

[0008] Thus, these systems are generally made up of a multitude of parts which do not facilitate assembly and which results in a system that is not economical to to manufacture.

[0009] Furthermore, this increases the risk of system malfunction. For example, with wear and tear, play may develop between the various parts, or the piston and / or push button may not return fully. The stroke is then incomplete, and the dose of fluid product dispensed is lower than expected, or the system may jam or become difficult to use.

[0010] Moreover, the parts may be made of different materials, including materials adapted to their functionality, complicating recycling.

[0011] There is therefore a need for a solution that resolves at least some of the disadvantages of the prior art while maintaining a system that is advantageously simple and economical to manufacture. Summary of the invention

[0012] Thus, the invention relates to an actuation head configured to be mounted on a fluid product distribution body comprising a pipette,

[0013] the actuating head comprising a piston and an actuator whose translation from an actuated extreme position to a rest position allows aspiration of the fluid product into the pipette and a translation from the rest position to the actuated extreme position allows dispensing of the fluid product out of the pipette and a return means allowing the piston and actuator to return to the rest position,

[0014] the piston, the actuator and the return means being made in a single plastic piece.

[0015] The return means allows for an automatic, or spontaneous, return of the piston and actuator, meaning that the piston and actuator return to their rest position on their own after descending, without the user needing to intervene.

[0016] The fact that the piston, actuator, and return mechanism are made in a single piece also allows for a smooth return movement. Unlike a conventional helical spring, the piston and actuator return to their rest position without any abrupt movement. The return movement is therefore more easily controlled.

[0017] Furthermore, this prevents one of the parts from becoming defective or one of them from becoming misaligned, resulting in a malfunction of the distributor for which the distribution head is intended.

[0018] Finally, since the whole thing is made of plastic, recycling the dispenser and, consequently, recycling the receptacle for which it is intended are facilitated.

[0063] The invention will be better understood, and other features and advantages thereof will become apparent upon reading the following detailed description, of at least two embodiments of the invention given by way of purely illustrative and non-limiting examples, with reference to the accompanying schematic drawings in which:

[0064] - Fig. 1 is a longitudinal cross-sectional view of a receptacle comprising a reservoir and a dispenser for fluid product according to a first embodiment of the invention in a rest position;

[0065] - [Fig. 2] is a longitudinal cross-sectional view of the distributor of [Fig. 1] in a extreme position activated;

[0066] - [Fig. 3] is a longitudinal cross-sectional view of a receptacle comprising a reservoir and a dispenser for fluid product according to a second embodiment of the invention in a rest position;

[0067] - [Fig. 4] is a perspective view of a first variant of the recall means figures 1 and 3;

[0068] - [Fig. 5] is a perspective view of a second variant of the recall means of the [Fig.4];

[0069] - [Fig. 6] is a perspective view of a third variant of the recall means of the [Fig.4];

[0070] - [Fig. 7] is a perspective view of a fourth variant of the recall means of the [Fig.4];

[0071] - [Fig. 8] is a perspective view of a fifth variant of the recall means of the [Fig.4]. Detailed description of the invention

[0072] By convention, the "axial" direction corresponds in the figures to that of the main X axis of a distributor 10 for a fluid product configured to be mounted removably on a fluid product reservoir 12, and the "radial" direction is orthogonal to the axial direction.

[0073] In the detailed description of the figures that follows, the terms "upper" and "lower" or "top" and "bottom" will be used without limitation in reference to the axial direction.

[0074] Similarly, the terms "outside or external" and "inside or internal" are used with reference to the radial direction, an outside element being radially further away from the X axis than an inside element.

[0075] Figures 1 and 2 illustrate a first embodiment of a receptacle 13 comprising a dispenser 10 for fluid product mounted in a removable / reversible manner on a reservoir 12.

[0076] The terms “removable” and “reversible” mean that the reservoir 12 is equipped with the distributor 10 and can be removed, particularly during the distribution of the fluid product, without causing destruction or deformation of either of the two elements.

[0077] The fluid product is of the type lotion, gel, perfume, serum or cream for example, used for cosmetic purposes or for pharmaceutical treatments.

[0078] The distributor 10 comprises an actuating head 14 and a distribution body 16. The removable connection between the distributor 10 and the reservoir 12 is made via the distribution body 16.

[0079] The distribution body 16 comprises:

[0080] - a pipette 18, and

[0081] - a closure system ensuring the sealing of the tank 12 when the body of distribution 16 is mounted on tank 12.

[0082] The pipette 18 is configured to allow storage of fluid product for distribution and to be housed inside the reservoir 12.

[0083] The reservoir 12 is configured to contain the fluid product and to receive the pipette 18.

[0084] The closure system ensures the sealing of the reservoir 12 when the pipette 18 is housed in it.

[0085] The reservoir 12 comprises a longitudinal wall 20 and an upper opening 22. The longitudinal wall 20 delimits an internal volume in which the fluid product can be stored. The upper opening 22 is delimited by a neck 24 connected to the longitudinal wall 20 by a frustoconical shoulder 26.

[0086] The closure system consists of a closure ring 28 configured to be removably attached to the reservoir 12.

[0087] To do this, the closing ring 28 includes closing means 30 cooperating with closing means 32 of the reservoir 12.

[0088] The closing means 30 of the closing ring 28 are located on an internal surface of a lower skirt 34.

[0089] The lower skirt 34 extends downwards from a transverse wall 36.

[0090] The means for closing the reservoir 12 are located on an external surface of the bottleneck 24.

[0091] This is a thread system 30, 32. The closing ring 28 can thus be fixed and / or removed from the reservoir 12 by a rotational movement of one relative to the other.

[0092] The distribution body 16 further includes an upper skirt 38 defining an internal housing extended by the pipette 18.

[0093] The internal housing thus forms a storage chamber 40 in fluidic connection with the pipette 18. More specifically, the lower part of the upper skirt 38 is connected to an upper end of the pipette 18 via the transverse wall 36. An opposite lower end of the pipette 18 is open and configured to be immersed in the reservoir 12 when the closing ring 28 is mounted on the reservoir 12.

[0094] The pipette 18 allows the storage of the dose of fluid product taken for distribution.

[0095] In this first embodiment, the distribution body 16 further includes an external skirt 42.

[0096] The outer skirt 42 encloses the locking ring 28 and the actuating head. It thus conceals these unsightly elements, in particular elements component of the actuation head.

[0097] Advantageously, in the illustrated embodiments, the pipette 18, the closing ring 28, and the outer skirt 42 forming the dispensing body 16 are made in one piece. In other words, they form a monolithic part. This simplifies design and assembly. It also eliminates the risk of play developing between the parts during use.

[0098] Preferably, the whole thing is made of plastic, facilitating the recycling of the dispenser and, consequently, the recycling of the receptacle for which it is intended.

[0099] The second embodiment differs from the first embodiment by the presence of an external envelope 43.

[0100] Advantageously, the outer envelope 43 is linked in rotation and translation to the distribution body 16.

[0101] In particular, in this second embodiment, the outer envelope 43 is rotationally linked with the distribution body 16 via the outer skirt 42 by a cooperation of vertical grooves located at their lower end and their upper end.

[0102] Furthermore, the outer casing 43 and the outer skirt 42 of the distribution body 16 are linked in translation by snap-fitting between them at their lower end and their upper end.

[0103] The outer casing 43 allows, for example, for an additional design and improved aesthetics of the receptacle 13.

[0104] In the embodiments represented here, the actuation head 14 includes an actuator 44, a piston 46 and a return means 48 allowing the piston 46 and the actuator 44 to return to the rest position.

[0105] According to the invention, the piston 46, the actuator 44 and the return means 48 are made from a single plastic piece. In other words, the piston 46, the actuator 44 and the return means 48 constitute a monolithic part.

[0106] In other words, unlike conventional systems comprising an independent helical spring, the compression or crushing of the return means 48 directly causes the piston 46 to descend without any intermediate part. The piston 46 is actuated by the actuator 44 and the return means 48.

[0107] Such a configuration allows for good retention of the actuator 44, the return means 48 and the piston 46. This facilitates the return of the actuator 44 and the piston 46 to the rest position and allows for homogeneous and durable movement over the long term.

[0108] Preferably, the piston 46, the actuator 44 and the return means 48 are made of polypropylene, for example post-consumer recycled polypropylene.

[0109] Polypropylene is a plastic material whose recycling cycle is well known.

[0110] Advantageously, the actuating head 14 is mounted on the distribution body 16 so that the actuator 44 is movable in axial translation relative to the outer skirt 42 of the distribution body 16 and the outer casing 43.

[0111] In the embodiments illustrated here, the distribution body 16 includes an upper housing 50 in which the return means 48 is housed. The upper housing 50 and the return means 48 are covered by the external skirt 42 of the distribution body 16.

[0112] In the second embodiment, the outer casing 43 also covers the upper housing 50 and the return means 48.

[0113] In the embodiments illustrated here, the piston 46 extends from an upper transverse wall 52 of the actuator 44 towards the interior of the receptacle 13. In other words, the piston 46 protrudes from the upper transverse wall of the actuator 44.

[0114] In particular, the actuator 44 has a housing in which the piston 46 is located.

[0115] When the actuating head 14 is mounted on the distribution body 16, the piston 46 is housed in the storage chamber 40 of the distribution body 16 and has an external diameter substantially similar to the internal diameter of the storage chamber 40 so that a translation of it can involve aspiration or distribution of the cosmetic product into the pipette 18.

[0116] Indeed, the actuator 44 being linked in translation with the piston 46, a pressure on the actuator 44 causes the piston 46 to descend in the storage chamber 40 from its rest position to its extreme position of sampling or distribution.

[0117] Similarly, a rise of the actuator 44 causes the rise of the piston 46.

[0118] The dose of fluid product is thus taken and / or distributed by a vertical translational movement of the actuator 44 which causes a translational (or sliding) movement of the piston 46 in the storage chamber 40.

[0119] When the pipette 18 is empty, a rise of the piston 46 causes the fluid product to be drawn up and the pipette 18 immersed in the reservoir 12 to be filled with the fluid product.

[0120] When the pipette 18 contains fluid product, a descent of the piston 46 causes the distribution of the fluid product contained in the pipette 18.

[0121] Advantageously, the return means 48 allows the piston 46 and the actuator 44 to return to the rest position.

[0122] The return is automatic, in other words spontaneous, meaning that the piston 46 and the actuator 44 return to their rest position on their own after being lowered, without the user needing to intervene.

[0123] Thus, when the user releases the actuator 44, the assembly automatically and spontaneously returns to its rest position, that is, without the user having need to intervene.

[0124] Figures 4 to 8 illustrate several examples of embodiments of an actuation head 14 which differ in the nature of the return means 48.

[0125] In each of these embodiments, the return means 48 forms a cavity 54 delimited by a wall and in which the piston 46 is housed.

[0126] Advantageously, the wall of the retrieval means 48 is flexible.

[0127] Thus, the flexibility of the wall allows the variability of the height of the cavity 54 during the translational movement of the actuator 44.

[0128] The cavity 54 thus has a variable height Hmax, Hmin. The height Hmax is maximum when the piston 46 and the actuator 44 are in the rest position, and the height Hmin is minimum when the piston 46 and the actuator 44 are in the actuated extreme position.

[0129] Thus, when the piston 46 and the actuator 44 are in the rest position, the height is at its maximum Hmax.

[0130] During the descent of the piston 46 and the actuator 44, the height of the cavity 54 decreases to a minimum height Hmin. The piston 46 and the actuator 44 are then in an extreme position of sampling or dispensing.

[0131] In other words, the recall means 48 has a deployed position illustrated in [Fig.1] corresponding to a rest position and a retracted position illustrated in [Fig.2] corresponding to an extreme picking or distribution position.

[0132] Advantageously, the flexible wall is a lateral flexible wall. In other words, the cavity 54 is delimited by a lateral flexible wall.

[0133] In the embodiments shown, the return means 48, here the flexible wall, is connected to the actuator 44 and is in material continuity with it. The return means 48 and the actuator 44 then have substantially identical diameters.

[0134] In other embodiments not shown, the return means 48 is connected to the piston 46 and is continuous with it in material. The return means 48 then has a diameter substantially identical to that of the piston 46.

[0135] The flexible wall can be a solid wall or a perforated wall.

[0136] Advantageously, the wall of the return means 48 is formed of a plurality of strips 56 of material. The strips 56 of material delimit the cavity 54 in which the piston 46 is housed.

[0137] Advantageously, the return means 48 includes a lower positioning ring 58. The positioning ring 58 allows the return means 48 to be held in position within the distribution body 16.

[0138] In particular, when the wall of the return means 48 is formed of strips 56 of material, each of the strips 56 of material is linked to the positioning ring 58 at its lower end, ensuring that it is held in position, in particular with a good spacing between them.

[0139] Preferably, the positioning ring 58 bears against the closing ring 28, for example, against its transverse wall 36, and the return means 48 encloses the upper skirt 38 of the closing ring 28, as shown in the illustrated embodiments. In other words, the upper skirt 38 of the closing ring 28 is located in the cavity 54 of the return means 48.

[0140] In the first, second and third embodiments of the return means 48 shown respectively in figures 1 to 4, 5 and 6, the wall of the return means 48 is formed of a plurality of strips 56 of material extending helically from an upper end projecting from the actuator 44 to an opposite lower end connected to the positioning ring 58.

[0141] In the first embodiment of the return means 48 visible in figures 1 to 4, the wall of the return means 48 is formed of four strips 56 of material extending helically and winding in the same direction of rotation around the piston 46.

[0142] The helical winding ensures the flexibility of the wall of the lifting means 48 and its height variability.

[0143] In the second embodiment of the return means 48 illustrated in [Fig.5], the wall of the return means 48 is formed of two strips 56 of material extending helically and winding in the same direction of rotation around the piston 46.

[0144] In the third embodiment of the return means 48 illustrated in [Fig.6], the wall of the return means 48 is formed of four helically extending bands 56 of material winding in two opposite directions of rotation around the piston 46. In other words, two bands 56 of material wind clockwise and two bands 56 wind counterclockwise, causing them to cross at certain points.

[0145] In the fourth embodiment of the return means 48 illustrated in [Fig.7], the wall of the return means 48 is formed of bands 56 of material which are transverse rings in the extension of the actuator 44. In other words, the bands 56 of material extend annularily around the piston 46.

[0146] The wall of the lifting means 48 is thus formed of transverse rings stacked parallel to each other and connected to each other by bridges of material 60.

[0147] The material bridges 60 ensure the flexibility of the wall of the lifting means 48 and its height variability.

[0148] In this embodiment example, the material bridges 60 are offset.

[0149] In other embodiment examples not shown, the material bridges are aligned.

[0150] The upper ring is linked to the actuator 44 by material bridges 60. The ring lower corresponds to positioning ring 58.

[0151] In the fifth embodiment of the return means 48 illustrated in [Fig. 8], the flexible wall is formed by three strips 56 of material projecting from the external surface of the piston 46 and regularly distributed around the piston 46. The strips 56 extend longitudinally from an upper end 60 located on the external wall of the piston 46 to an opposite lower end 62 where they are connected to the positioning ring 58. The strips 56 are regularly distributed on the positioning ring 58.

[0152] Each of the bands 56 thus extends downwards so that the cavity 54 has a concave shape towards the lower part of the distributor 10.

[0153] The flexibility of each of the bands 56 allows the variability of the height Hmax, Hmin of the cavity 54 of the return means 48 and the return of the piston 46 and the actuator 44 to the rest position.

[0154] Advantageously, the dispenser 10 is made of a single material. Preferably, the dispenser 10 is made entirely of plastic.

[0155] In other words, the actuating head 14 and the distribution body 16 are made of the same material, or at least of similar materials.

[0156] Similar materials are understood to be materials which will have at least one common recycling circuit.

[0157] Using the same material, or at least similar materials, to manufacture the various parts of the refill 16 is particularly advantageous for their recycling after use of the fluid product. Indeed, the presence of different materials presents drawbacks during recycling, as the parts must be separated. Using the same material allows all the parts of the refill 16 to be disposed of together without having to disassemble it, thus facilitating recycling.

[0158] The material may be selected from polypropylene (PP), polyethylene terephthalate (PET), recycled polyethylene terephthalate (R-PET), a thermoplastic elastomer (TPE), polyethylene (PE), such as low-density polyethylene (LDPE) and / or high-density polyethylene (HDPE), a composite material, a post-consumer recycled (PCR) material and / or a similar material.

[0159] Preferably, the material is chosen from polypropylene, polyethylene terephthalate, post-consumer recycled polypropylene, post-consumer recycled polyethylene terephthalate, or a mixture of these.

[0160] Polypropylene and polyethylene terephthalate are two plastics whose recycling cycle is well known.

[0161] Typically, the reservoir 12 is made of glass. It can also be made of plastic, wood, metal, hybrid material or mixtures thereof.

[0162] Disassembly of the actuating head 14 and the distribution body 16 and the Disassembly of the distribution body 16 and the reservoir 12 being easily carried out, the fact that the reservoir 12 is made of a different material does not complicate recycling, each of the parts being recycled in a clean recycling cycle.

[0163] Advantageously, the receptacle 13 is made of a single material, preferably a plastic material such as polypropylene.
