Description

Title of the invention: Cosmetic dispenser of a fluid product

[0001] The present invention relates to an elastically compressible dispenser of a fluid product, in particular a cosmetic fluid product such as a cream and in particular a lip balm.

[0002] Compressible type dispensers are typically those capable of delivering a fluid product under the action of manual pressure applied to their walls.

[0003] Document US 2019038001 A1 discloses a compressible dispenser for fluid product. This dispenser comprises an elastically compressible body, a liquid product dispensing member having a fluid outlet orifice, and a cap fixed to the body to cover and protect the dispensing member. The dispenser comprises a flexible pouch which is arranged inside the body and which contains the fluid product. The dispensing member is in the form of a dip tube, one end of which extends towards the bottom of the flexible pouch and its other end comprises a nipple provided with a slot forming the outlet orifice.

[0004] This dispenser, however, has the disadvantage that it is not designed for dispensing a cosmetic product onto the lips.

[0005] Also known from document JP 2012213469 A is a compact applicator for the lips. The applicator, of wide and flat shape, being sandwiched between the two lips, allows a cosmetic formula to be applied simultaneously to both lips. A formula outlet orifice is present on each face of the applicator.

[0006] This applicator is however not very ergonomic and the application of the cosmetic formula on the lips is not easy.

[0007] The present invention proposes to remedy these drawbacks.

[0008] The invention thus relates to a compressible dispenser of fluid product, with a longitudinal axis and of the type comprising an elastically compressible body intended to receive the fluid product, an applicator mounted on the elastically compressible body and extending it longitudinally, and a longitudinal dispensing member for said fluid product intended to convey the fluid product from the interior of the elastically compressible body towards the applicator, the applicator being provided with two outlet orifices opening onto an external surface of the applicator and allowing the dispensing of the fluid product.

[0009] According to the invention, each outlet orifice has, at the level of the external surface of the applicator, an elongated shape along an axis, the axes of the two outlet orifices belonging to the same plane parallel to the longitudinal axis, preferably a plane passing through the longitudinal axis.

[0010] Alternatively, or in combination, the dispenser is configured so that, at from each orifice, the path of the fluid product opens onto the external surface of the applicator in a longitudinal direction.

[0011] Thus, thanks to the specific structure of the dispenser, it is possible to apply the fluid product to both lips at the same time, in a simple and effective lateral gesture.

[0012] The axes of the two outlet ports may be non-parallel, and may further be symmetrical with respect to the longitudinal axis of the distributor.

[0013] The distributor may have a large dimension and a small dimension transversely, and said plane may be oriented in the direction of the large dimension or in the direction of the small dimension. The distributor may in particular be ellipsoid-shaped.

[0014] The dispenser may comprise a flexible pouch disposed inside the elastically compressible body and which comprises the fluid product to be dispensed. The use of a flexible pouch coupled with a valve system prevents air from escaping from the elastically compressible body and thus allows a better rate of restitution of the fluid product, by increasing the pressure to press on the pouch. In addition, the use of a flexible pouch coupled with a valve system is more hygienic, with on the one hand an applicator that is easier to clean and on the other hand an airless system preventing any contamination of the fluid product in the elastically compressible body. It is also possible to envisage limiting or even eliminating preservatives in the product if the pouch is filled under sterile conditions.

[0015] The dispenser may successively comprise between the dispensing member and the applicator a connector and a distributor.

[0016] The connector may be configured to direct the fluid product from the elastically compressible body (whether or not it is provided with a flexible bag) towards the distributor, and the connector may comprise an orifice for conveying air towards the interior of the elastically compressible body, as well as a washer acting as a valve provided on said orifice so as to close said orifice when a user exerts manual pressure on the elastically compressible body.

[0017] The distributor may be configured to convey to the two outlet orifices the product coming from the dispensing member and having passed through the first connector, the distributor comprising two longitudinal tubes which each open onto an outlet orifice.

[0018] Each longitudinal tube is advantageously covered with a non-return valve, thus preventing air from entering the distributor.

[0019] The applicator may be convex in shape and the profile of the outlet orifices on the outer surface of the applicator may also be convex.

[0020] The distributor may be generally convex and the elastically compressible body may comprise a flat.

[0021] A portion of the applicator comprising a first outlet orifice may be convex, while a portion of the applicator comprising a second outlet orifice may be concave.

[0022] The applicator may have a convex shape and the outlet orifices may each be located inside a flat of the applicator.

[0023] Each outlet orifice may be surrounded by a fluid product dosage marking, for example a screen printing marking, a groove or a rib.

[0058] As illustrated in Figures 1 to 3, a compressible dispenser 1 of fluid product according to the invention, of the fluid cosmetic product type such as a cream, in particular a lip balm, has a longitudinal axis X and comprises an elastically compressible body 2 intended to receive the fluid product, an applicator 3 mounted on the elastically compressible body 2 and extending it longitudinally, as well as a dispensing member 4 of the fluid product intended to convey the fluid product from the interior of the body 2 and towards the applicator 3. The dispenser 1 may also comprise a cover, not shown. The cover protects the applicator 3 when it is not in use.

[0059] The elastically compressible body 2, the applicator 3 and the dispensing member 4 each advantageously have a symmetry of revolution around the longitudinal axis X.

[0060] The elastically compressible body 2 is intended to be deformed by manual pressure. It is made of an elastically deformable material and its walls can be compressed while being sufficiently elastic to return to their initial shape when the pressure ceases. For this purpose, the elastically compressible body 2 can be made of rubber, elastomer or thermoplastic material. It has an upper orifice 2a.

[0061] The dispensing member 4, of longitudinal orientation, comprises a lower part comprising a plurality of longitudinal tabs 4a, the lower part being arranged inside the body 2. The dispensing member 4 also comprises a cylindrical upper part 4b which is surrounded by an annular rim 4c forming a collar and intended to bear on an upper annular edge 2b of the elastically compressible body 2 delimiting the upper orifice 2a. The collar 4c is advantageously provided with orifices 4d ([Fig.8]) allowing air to enter inside the body 2.

[0062] The applicator 3 is the part of the dispenser 1 allowing the application of the fluid cosmetic product, in particular on the lips of a user. It advantageously has a shape adapted to the lips which can be in a case convex and symmetrical or asymmetrical in order to deliver more formula on the lower lip which is more fleshy. The applicator 3 is mounted on the upper edge 2b of the body 2, for example by screwing around said upper edge 2b. The applicator 3 comprises, approximately halfway between its lower end and its upper end, an orifice made in a transverse wall 3a of the applicator 3. The orifice receives and longitudinally guides the upper end of the cylindrical part 4b of the dispensing member.

[0063] The applicator 3 is provided in its upper part with two outlet orifices 3c, 3d. Each outlet orifice 3c, 3d is advantageously in the form of a slot, that is to say a narrow and elongated opening. The axes A and A' of the orifices 3c and 3d respectively on the outer surface S of the applicator 3 are non-parallel and advantageously belong to a longitudinal plane B parallel to the longitudinal axis X of the dispenser 1. Preferably, the longitudinal axis X belongs to the longitudinal plane B. The axes A and A' may or may not be symmetrical with respect to the longitudinal axis X.

[0064] The profile SI, S2 of the orifices 3c, 3d on the surface of the applicator 3 may be a rectilinear profile, contained in a plane, and may be, for example, rectangular or oblong. It may also be envisaged that the profile SI, S2 of the orifices 3c, 3d on the surface of the applicator 3 is non-rectilinear, for example curved (and in particular concave or convex). In this case, the axis of the orifice on the outer surface of the applicator will be the axis passing through the two ends of the orifice, in the direction of its length, located on the outer surface of the applicator.

[0065] The operation of the dispenser 1 is as follows. First, the protective and closing cover of the applicator 3 is removed. Then, the compressible body 2 is pressed so as to deliver the product P at the orifices 3c, 3d of the applicator 3. The path of the product P from the inside of the compressible body 2 to the orifices 3c, 3d of the applicator 3 and passing through the dispensing member 4 is illustrated in Figures 1 and 2 by the arrows F. A user 5 then places his lips on the applicator 3 ([Fig.l]). The dispenser 1 is used horizontally (the longitudinal axis X of the dispenser 1 is arranged by the user 5 substantially horizontally), so that the outlet orifices 3c, 3d of the product P are aligned vertically, one above the other. The lips of the user 5 can thus be placed naturally on the applicator 3, one lip being placed opposite a slot 3c, 3d. The lower lip can be in contact with the slot 3c, while the upper lip can be in contact with the slot 3d. Thanks to the two orifices 3c, 3d which allow double dispensing, the user 5 will be able to spread the product simultaneously on his lower lip and on his upper lip, in a lateral gesture from one edge to the other.

[0066] The product P is pushed into the applicator 3 by simple pressure on the compressible body 2. The dosage of the quantity of product can be done at the free choice of the user 5 or via dosage indicators placed on the applicator 3.

[0067] In the embodiment illustrated in Figures 4 to 8, the dispenser 1 comprises a flexible pouch 9 which is arranged inside the elastically compressible body 2 and which contains the fluid product P to be dispensed. However, in all of the embodiments described in the present application, the dispenser may or may not comprise a flexible pouch.

[0068] The flexible pocket 9 can be fixed to a neck of the dispensing member 4, for example by welding.

[0069] The space E between the elastically compressible body 2 and the flexible pouch 9 fills with air as the pouch 9 empties of the product it contains. The orifices 4d present on the collar 4c of the dispensing member 4 allow air to enter the space E between the elastically compressible body 2 and the flexible pouch 9.

[0070] The dispenser 1 may comprise, between the dispensing member 4 and the applicator 3, a connector 6 and a distributor 7. The connector 6 makes it possible to direct the product P from the body 2 towards the distributor 7.

[0071] The connector 6 covers the upper orifice 2a of the compressible body 2 and the upper cylindrical part 4b of the dispensing member 4. The collar 4c of the dispensing member 4 rests on the upper annular edge 2b of the body 2 which surrounds and delimits the orifice 2a of the body 2. The collar 4c is bordered by a longitudinal annular rib 2c of the body 2.

[0072] The connector 6 comprises a cylindrical lower part and a substantially frustoconical upper part. It comprises two outer annular walls 6a which are positioned around the rib 2c of the body 2, as well as two inner annular walls 6b delimiting an annular space into which the upper end of the cylindrical part 4b of the distribution member 4 is inserted.

[0073] The connector 6 further comprises a lateral orifice 6c for conveying air towards the interior of the body 2 via the orifices 4d of the distribution member. Opposite the orifice 6c is a deformable washer 6d capable of acting as a valve and thus closing the orifice 6c when the user exerts manual pressure on the body 2.

[0074] The distributor 7 is intended to convey the product P coming from the distribution member 4 and having passed through the first connector 6 towards the two outlet orifices 3c, 3d. The distributor 7 comprises a cylindrical base 7a resting on the upper annular edge 6e of the connector 6. The cylindrical base 7a is extended by two longitudinal tubes 7b which each open onto an outlet orifice 3c, 3d. Each of the two longitudinal tubes 7b is advantageously covered with a non-return valve 8. The non-return valves 8 may be duckbill type non-return valves. Duckbill non-return valves allow the flow to flow through a flexible tube whose end has a natural flattened shape. This flattened shape resembles a duckbill, hence the name of the valve. The flow opens the flattened end of the duckbill, allowing fluid to pass through.When pressure is removed from the inlet side, the tip of the duckbill returns to its flattened state, cutting off the flow.

[0075] When using the dispenser 1, the manual pressure exerted on the elastically deformable body 2 is transmitted to the flexible bag 9 which contains the fluid product P. The latter then flows into the dispensing member 4, then into the first connector 6 and into the distributor 7 to the non-return valves 8, which will cause the valves 8 to open and thus the product P to be ejected through the outlet orifices 3c, 3d of the applicator 3. No air is allowed to enter the flexible bag 9 through the end of the valves 8. This characteristic guarantees the stability and preservation of the formulation of the fluid product. The compression exerted on the elastically deformable body 2 also has the effect of pressing the deformable washer 6d against the orifice 6c and preventing air from escaping from the space E through the orifice 6c.

[0076] When the manual pressure exerted on the walls of the elastically compressible body 2 ceases, the body 2 relaxes, the end of the non-return valves 8 closes and the deformable washer 6d deforms so as to no longer obstruct the orifice 6c. Air enters the space E between the elastically compressible body 2 and the flexible bag 9 via the orifice 6c. The volume of air which then enters the space E then compensates for the volume of product ejected from the flexible bag 9. As a result, the elastically compressible body 2 returns to its initial shape.

[0077] A flange 10 advantageously reinforces the stability and sealing of the distributor 1. The flange 10 is snapped or clipped onto the elastically compressible body using two clamps 10a arranged on either side of the axis X of the distributor 1. Each clamp 10a is inserted into a receiving zone 2d arranged on the upper annular edge 2b of the elastically compressible body 2. The flange 10 is generally in the form of a spherical segment, the upper part of the flange 10 coming into contact with the applicator 3. The flange 10 thus surrounds the connector 6 and the distributor 7 and the upper part of the flange 10 is provided with an opening surrounding the non-return valves 8.

[0078] Finally, a protective and sealing cover 11 covers the applicator 3.

[0079] In the embodiment illustrated in Figures 4 to 8, the dispenser 1 is continuously convex, that is to say that the dispenser 1 is seen rounded from an external reference frame. In particular, the applicator 3 is convex in shape and the profile SI, S2 of the outlet orifices 3c, 3d on the surface of the applicator 3 is also convex. In particular, the profile SI, S2 of the outlet orifices 3c, 3d on the surface of the applicator 3 may be a convex ellipse.

[0080] The distributor 1 may have a large dimension and a small dimension transversely, and the plane B of the axes A, A' of the outlet orifices 3c, 3d may be oriented in the direction of the large dimension ([Fig.7]) or in the direction of the small dimension. The distributor 1 may in particular be ellipsoid-shaped.

[0081] In the embodiment illustrated in Figures 9 to 14, the elastically compressible body 2 of the generally convex dispenser 1 may comprise a flat area or flat 2e. The flat 2e creates a support area for the thumb, thus improving grip and facilitating pressure on the container to release the fluid product. A better grip is also obtained on the dispenser 1 when applying the fluid product to the lips. Finally, the flat 2e can act as a base when the dispenser 1 is placed.

[0082] As illustrated in Figures 15 to 20, the applicator 3 may be half-convex, half-concave, so as to perfectly match the shape of the lips. Thus, a portion of the applicator 3 comprising a first outlet orifice 3c may be convex, while a portion of the applicator comprising a second outlet orifice 3d may be concave. A convex surface thus accommodates the upper lip, and a wider concave surface is adapted to the size of the lower lip. The lips naturally rest on the applicator 3 and can thus slide easily when the product is applied simultaneously to both lips.

[0083] This asymmetrical applicator 3 also aims to distribute more cream on the lower lip which is fuller than the upper lip.

[0084] In another embodiment (figures 21 to 26), the applicator 3 has a convex shape and the outlet orifices 3c, 3d are each located inside a flat area 3e (flat). The applicator 3 being used horizontally, the two flats 3e which form bevels serve as a natural stop for the lips in order to prevent the applicator 3 and therefore the fluid product from entering the mouth. The lips of The user 5 will naturally rest on the bevels. These bevels will also guide the lips during the translational movement carried out during the application of the balm.

[0085] In this embodiment, the slots 3c, 3d are advantageously aligned in a direction corresponding to the small transverse dimension of the dispenser 1. The user thus places the large transverse dimension of the dispenser horizontally when dispensing the product onto the lips. In the previous embodiments illustrated in Figures 4 to 21, the slots 3c, 3d were advantageously aligned in a direction corresponding to the large transverse dimension of the dispenser 1.

[0086] Finally, in a last embodiment, illustrated in figures 27 to 33, and which can be combined with each of the previous embodiments, a system for dosing the fluid product for a given pressure is added, to improve the use of the dispenser 1.

[0087] For a single dosage (figures 27 to 29), the valves 8 can themselves be used. Indeed, by pressing the flexible body, the product P will come out and when it covers the valves this means that the correct dosage has been reached.

[0088] For a double dosage (figures 30 to 33), markings 12 framing the duckbill flaps can be screen printed on the applicator 3. A first dosage for “dry lips” is achieved when the flaps are covered with product ([Fig.32]), and a second dosage for “very dry lips” is achieved when the screen prints 12 framing the flaps 8 are covered ([Fig.33]).
