Description

DESCRIPTION

TITLE: A device for storing and dispensing cosmetic products comprising two intermediate chambers, an associated dispensing method

The present invention relates to a device for storing and dispensing cosmetic products.

The present invention also relates to a method for dispensing cosmetic products.

More generally, a “cosmetic product” is a product as defined in the Regulation CEN- 1223/2009 of the European Parliament and Counsel dated on November 30th, 2009, relating to cosmetic products.

The document US 3,347,420 describes a cosmetic product dispenser configured to dispense two cosmetic products simultaneously. The dispenser comprises two reservoirs respectively defining an inner volume storing a respective cosmetic product. The dispenser further comprises two intermediate chambers communicating with each reservoir via a respective dip tube. The dispenser further comprises a dispense end communicating each intermediate chamber with the outside of the dispenser.

Dispensing the cosmetic product by means of the dispenser according to this document US 3,347,420 comprises the separate pressing on each reservoir to fill each intermediate chamber and the flow of the cosmetic product from each intermediate chamber via the dispense end by flipping the dispenser over.

However, the user of the dispenser should measure by himself or herself the amount of each cosmetic product by pressing on each reservoir more or less hard and for a more or less long period. Afterwards, the user should flip the dispenser over to deliver the cosmetic products. The practicality of the dispense could therefore be improved.

The invention aims to provide a device for storing and dispensing cosmetic products having to be stored separately and which is more practical to use, while supplying a controlled dose of the products.

To this end, an object of the invention is a device for storing and dispensing cosmetic products configured to simultaneously dispense at least two cosmetic products, the storage and dispensing device comprising:

- at least two reservoirs respectively defining an inner volume capable of storing a respective cosmetic product, - for each reservoir, an intermediate chamber arranged in the inner volume of the respective reservoir and being in fluidic communication with the corresponding inner volume,

- an application and/or dispensing head including for each reservoir, a respective dip tube, each dip tube including a distal end opening into the intermediate chamber, and

- a member for pressurizing the intermediate chambers which can be actuated to cause the dispense of the two cosmetic products through the respective dip tubes.

The pressurization member allows pressurizing the intermediate chambers to dispense the two cosmetic products. Thus, it is not necessary to successively press on each reservoir.

Furthermore, the dispense of the cosmetic products being performed via the respective dip tubes after actuation of the pressurization member, the storage and dispensing device could be used in many positions for dispensing the cosmetic products.

Hence, the practicality of use, as well as the accuracy of dosage of the products dispensed by means of the storage and dispensing device are improved.

According to one embodiment, the pressurization member includes a skirt wrapping the two reservoirs at least partially, the reservoirs being capable of being compressed by the skirt upon a manual press on the skirt, the skirt being movable between:

- a rest position in which the skirt and the reservoirs are at rest, and

- a dispense position in which the skirt is pressed against the reservoirs so as to compress their inner volume.

The skirt is easy to use since it allows directly compressing the two reservoirs by manual pressure.

Hence, the practicality of the storage and dispense device is further improved.

According to one embodiment, the skirt comprises two flexible support sidewalls, the reservoirs being arranged between the sidewalls, the sidewalls being capable of being brought close to one another.

According to one embodiment, the skirt and each intermediate chamber are made integrally in one-piece.

With the aforementioned feature, the manufacture of the storage and dispensing device is simplified since a smaller number of elements should be assembled.

According to one embodiment, at least one through aperture is formed through each intermediate chamber, the or each aperture ensuring a fluidic communication between the intermediate chamber and the corresponding inner volume.

Thanks to the through apertures, the cosmetic product can be easily conveyed between the reservoir and the associated intermediate chamber. According to one embodiment, each reservoir delimits a bottleneck, the skirt being capable of being hermetically fitted on each bottleneck.

Thanks to the hermetic engagement, the assembly of the storage and dispensing device is simple and quick.

According to one embodiment, the application and/or dispensing head further comprises a base hermetically clasping a portion of the skirt and delimiting the dip tubes.

Thanks to the base, the risk of air leak between each chamber and the associated reservoir is reduced. Hence, the dispense of the cosmetic products is improved when actuating the pressurization member.

According to one embodiment, the application and/or dispensing head comprises a cap defining an inner face onto which each dip tube opens, and an outer face opposite to the inner face, the cap comprising for each dip tube, an outlet orifice crossing it from the inner face to the outer face.

With the cap, the dip tubes are not exposed. Hence, the risk of them being damaged is lower. Furthermore, the appearance of the storage and dispensing device is improved since only the cap is visible.

According to one embodiment, the cap is overmolded over the base.

Thanks to overmolding, the manufacture of the storage and dispensing device is easy to carry out on an industrial scale. Furthermore, overmolding ensures that the base and the cap remain firmly secured together.

According to one embodiment, at least one of the cap and the base has at least one region deformable with respect to the other one of the cap and the base, the deformable region being arranged opposite or adjacent to a dispense orifice located at a proximal end of each dip tube, each proximal end being opposite to the distal end of the corresponding dip tube, the deformable region being capable of switching from a rest configuration in which the deformable region bears on the other one of the cap and the base at least at the periphery of the dispense orifice, and a product dispense configuration, in which the deformable region is deformed by the product coming out of the dispense orifice, at least a spillway being formed between the other one of the cap and the base and the deformable region up to a product outlet orifice out of the dispense head.

The deformation of the cap and/or of the base inside areas defined by the fastening inner lines to form the spillways limits the amount of product in a dead volume. Indeed, after dispensing, each cosmetic product is either expelled through the associated outlet orifice, or reintroduced into the associated intermediate chamber. Hence, the residual cosmetic product volume between the base and the cap is substantially reduced since the cap is in the rest configuration, thereby limiting the risk of residual product drying after a dispense operation, which might disturb a subsequent dispense operation.

Furthermore, thanks to the spillways, the cosmetic products are not in contact with each other before reaching the outer face of the cap. Hence, any reaction between the cosmetic products is substantially reduced before said products reach the outer face. Such an arrangement is particularly advantageous when the products contained in each of the reservoirs are likely to react with each other and should be mixed extemporaneously to be fully effective.

According to one embodiment, the base delimits a plurality of holes crossing it, each hole being overmolded by the cap, the plurality of overmolded holes forming a respective periphery of each spillway.

The fact that the overmolded area delimits ach spillway makes each spillway hermetic from each other and avoids any interaction between the cosmetic products in the spillways.

According to one embodiment, each reservoir defines at its periphery at least one bulge on which the skirt is capable of bearing when the skirt is in the dispense position, each reservoir preferably defining two bulges opposite with respect to the reservoir.

Thanks to the bulges, the compression of each reservoir is improved.

The present invention also relates to a method for dispensing cosmetic products as defined hereinabove, the method comprising:

- filling each intermediate chamber with the cosmetic product stored in the reservoir associated with the intermediate chamber,

- pressurizing the intermediate chambers by actuating the pressurization member, and

- simultaneously dispensing the cosmetic products through the respective dip tubes. According to one embodiment, the filling step is performed by shaking the storage and dispensing device, the cosmetic product flowing from each reservoir towards the respective intermediate chamber via the associated fluidic communication.

Shaking the storage and dispensing device is simple to implement, and even with one hand. Thanks to this action, the chambers are substantially filled with the same amount of cosmetic product.

The invention will be better understood upon reading the following description, given only as example, and made with reference to the appended drawings wherein:

- [Fig. 1] Figure 1 is an exploded perspective view of a storage and dispensing device according to the invention, - [Fig. 2] Figure 2 is a sectional view of the storage and dispensing device of Figure

1 , and

- [Fig. 3] Figure 3 is a sectional view, according to the same sectional plane as Figure

2, of an applicator of the storage and dispensing device of Figures 1 and 2;

- [Fig. 4] Figure 4 is a perspective view of the base of the applicator of the storage and dispensing device of Figure 1 ;

- [Fig. 5] Figure 5 is a top view of the cosmetic product applicator of Figure 3.

A device for storing and dispensing cosmetic products is shown in Figures 1 and 2.

In this example, the storage and dispensing device 10 comprises two reservoirs 15 for separate storing the products separately, two intermediate chambers 20 for dispensing the products separately, a pressurization member 30, a product dispensing head which herein forms an applicator 35 and optionally a lid 37.

For example, the reservoirs 15 respectively have a bottle-like shape including a body 40 and a bottleneck 45.

Each reservoir 15 defines an inner volume 50 capable of storing a respective cosmetic product.

For example, the cosmetic products are two products intended to be stored separately and to be dispensed simultaneously out of the storage and dispensing device 10 in order to be applied together or in the form of a mixture formed outside the storage and dispensing device 10 over a body surface of a user.

For example, the cosmetic products are cosmetic products for dyeing, makeup, hygiene or care of a body surface of the user.

For example, these products are liquid products capable of forming an antiperspirant when they are brought into contact. Thus, the two cosmetic products are capable of reacting to form a solid compound capable of plugging sweat pores of a user of the storage and dispensing device 10.

The reservoirs 15 are herein made integrally in one-piece.

For example, the reservoirs 15 are made of a flexible material capable of being deformed by a manual action. Advantageously, the reservoirs 15 are made of polypropylene (PP) or polyethylene (PE) or of several layers of several materials where there is a need for an enhanced barrier for sensitive formulas.

In the example shown in Figure 1 , each reservoir 15 defines at its periphery at least one bulge 55. Preferably, each reservoir 15 defines two bulges 55 opposite each other with respect to the body 40. Each bulge 55 is a privileged area allowing, when pressed, deforming and compressing the associated reservoir 15 in a reliable and repeatable manner. Advantageously, each bottleneck 45 defines an annular boss 60 (cf. Figure 2) capable of cooperating with the pressurization member 30 as described hereinafter.

As shown in Figure 2, each intermediate chamber 20 is arranged in the inner volume 50 of the respective reservoir 15. Preferably, the intermediate chambers 20 extend over a smaller height than a height of each body 40.

Preferably, each intermediate chamber 20 is in the form of a cupule. For example, the two intermediate chambers 20 are identical.

Each intermediate chamber 20 defines an intermediate volume 62 substantially smaller than the inner volume 50. For example, the intermediate volume 62 is smaller than 10% of the inner volume 50 and is comprised in particular between 1 % and 5%, and in particular close to 2% of the inner volume 50.

Each intermediate chamber 20 is in fluidic communication with the corresponding inner volume 50. Preferably, at least one aperture 65 is formed through each intermediate chamber 20 ensuring a fluidic communication between the intermediate chamber 20 and the inner volume 50 in which the intermediate chamber 20 is arranged. For example, a plurality of apertures 65, for example between two and six apertures 65, in particular four apertures 65 are formed in each intermediate chamber 20. The apertures 65 are distributed around each intermediate chamber 20. Material bridges 70 separate two contiguous apertures 65.

Preferably, the amount of cosmetic product stored in each inner volume 50 is such that the corresponding intermediate chamber 20 is not immersed in the cosmetic product. Nonetheless, thanks to the apertures 65, the cosmetic product can move between the inner volume 50 and the intermediate volume 62.

The pressurization member 30 is configured to pressurize each of the reservoirs 15, this pressure being transmitted to the intermediate chambers 20 via the apertures 65.

For example, the pressurization member 30 is a skirt wrapping at least partially the two reservoirs 15.

For example, the skirt 30 comprises two opposite flexible sidewalls 75. It includes for each sidewall 75, two inner projections (not shown) forming bearing elements. Each projection bears on the reservoirs 15, more particularly on the bulges 55 of the reservoirs 15. The projections are capable of bearing on the reservoirs 15 in order to compress the reservoirs 15 when the sidewalls 75 are brought close to one another.

For example, the skirt 30 is capable of switching from a rest position in which the skirt 30 and the reservoirs 15 are at rest, into a dispense position in which the skirt 30 bears against the reservoirs 15 to compress the reservoirs. In the dispense position, the sidewalls 75 of the skirt 30 are brought close to one another, in particular by clasping between the fingers of a user.

Preferably, the skirt 30 and the intermediate chambers 20 are made integrally in one-piece, forming one single part.

For example, the skirt 30 defines a terminal plate 79 connecting the upper edges of the sidewalls 75 and, for each reservoir 15, a neck 80A defining an annular groove 80 capable of receiving the boss 60 of each bottleneck 45 in order to be snap-fitted onto the reservoirs.

The neck 80A projects away from the body 40 over the terminal plate 79.

Preferably, the skirt 30 is hermetically snap-fitted on the reservoir 15. In other words, snap-fitting is such that no fluid could substantially flow in the annular grooves 80, between the neck 80A and the bosses 60.

Referring to Figure 3, the applicator 35 herein comprises two dip tubes 85. In this example, it further comprises a base 90 and an at least partially deformable cap 95 covering the base 90.

Each dip tube 85 is respectively associated with a reservoir 15 to be immersed exclusively in the chamber 20 received in this reservoir.

Each dip tube 85 extends between a distal end 100 and a proximal end 105. The distal end 100 opens into a respective intermediate chamber 20. The proximal end 105 opens outside the associated reservoir 15.

Each dip tube 85 is capable of making the cosmetic product flow from the intermediate chamber 20 towards the outside of the reservoir 15. Thus, the unique fluidic communication between the inner volumes 50 and the outside of the storage and dispensing device 10 passes through the dip tubes 85.

As shown in Figure 4, the base 90 includes a bearing surface 106 of the cap 95, an inner surface opposite to the bearing surface 106 and a rim 107 projecting from the bearing surface 106 at the periphery of the latter, in the same direction as the dip tubes 85, around these.

The dip tubes 85 open out at their proximal end 105 into a product dispense orifice 104 extending through the bearing surface 106.

Preferably, the base 90 delimits a plurality of holes 110 crossing it therethrough.

The holes 1 10 extend over at least one fastening inner line 108 of the cap 95 respectively located around each outlet orifice 104 opening out at the proximal end of a dip tube 85.

The holes 1 10 further define at least one fastening outer line 109 of the cap 95 extending outside the fastening inner lines 108. In the example shown in Figure 4, at least one fastening outer line 109 advantageously extends through the rim 107 to ensure a peripheral fastening of the cap 95 on the rim 107.

Each fastening inner line 108 herein has a closed contour, advantageously in the form of a gutter, with a rounded body 109A surrounding the orifice 104, and a tip 109B.

In the example of Figure 4, the tips 109B of the inner lines 108 are arranged in a staggered manner.

The fastening inner lines 108 are herein devoid of any overlap so that the inner regions delimited thereby are totally separate.

For example, the base 90 is made of a rigid material which is less deformable than the cap 95, such as a metal or a plastic material, in particular polyethylene terephthalate (PET), polypropylene (PP), or polyamide (PA), polybutylene terephthalate (PBT), polyketone (PK), for example the material POKETONE ™ commercialized by the HYOSUNG company, acrylonitrile butadiene styrene (ABS), polycarbonate (PC), or a mixture of these materials.

The cap 95 has a shape substantially complementary to the bearing surface 106 and to the rim 107 so as to bear at rest on the bearing surface 106 and on the rim 107. Thus, it includes a central portion 121 A applied on the bearing surface 106, and a peripheral flanged edge 121 B applied on the rim 107.

The cap 95 defines an inner face 115 directed towards the base 90 and an outer face 120 directed towards the outside of the storage and dispensing device 10. The inner 115 and outer 120 faces are opposite to each other with respect to the cap 95.

The cap 95 is overmolded over the base 90. More particularly, each hole 110 of the base 90 is overmolded by the cap 95. Some material of the cap 95 extends through each hole 110 and forms a material bridge outside the hole 1 10, over the surface opposite to the bearing surface 106, to clasp the base 90 between the inner face 1 15 and the material bridge.

Hence, there is a material continuity between an outer portion of the cap 95 applied on the bearing surface 106 of the base 90 and an inner portion of the cap 95 formed by the material bridges through each hole 1 10 and by blocking stops projecting on the inner surface of the base 90.

Thus, the base 90 is sandwiched between the inner and outer portions of the cap 95.

This arrangement of the cap 95 over the base 90 reinforces fastening of the cap 95 on the base 90 and limits the risk of discharge of the product. Thus, the cap 95 defines, opposite each fastening inner line 108, and opposite each fastening outer line 109, a region 122 fastened on the base 90. Inside each region 122 fastened on the base 90 located opposite a fastening inner line 108, the cap defines a deformable region 123 when dispensing the product, freely deformable relative to the bearing surface 106. In particular, the deformable region 123 extends opposite the product dispense orifice 104.

For example, the cap 95 is made of an elastically-deformable plastic material such as polyethylene (PE), poly(styrene-ethylene-butylene-styrene) (SEBS), poly(ethylene-vinyl acetate) (EVA), or others.

Preferably, the proximal end 105 of each dip tube 85 opens onto the inner face 1 15. The cap 95 comprises for each dip tube 85, an outlet orifice 125 crossing it from the inner face 115 to the outer face 120.

The outer face 120 can be applied directly on a portion of the body of the user, such as the armpits. When the products come out via the outlet orifices 125, they can be mixed over the outer face 120.

The cap 95 is elastically deformable between a rest configuration and a dispense configuration.

In the rest configuration, the deformable region 123 of the cap 95 tightly bears on the bearing surface 106. It covers the proximal end 105 of each dip tube 85, opposite the passage orifice 104, by its inner face 1 15, to prevent the dispense of the product out of the dip tube 85.

In the dispense configuration, the deformable region 123 of the cap 95 is elastically deformed by the cosmetic product coming out of the proximal end 105 and passing through the dispense orifice 104.

The deformable region 123 locally departs away from the bearing surface 106. Thus, it forms a spillway 130 between the base 90 and the cap 95.

The spillway 130 is delimited between the bearing surface 106 of the base 90 and the inner face 115 of the cap 95. The spillway is delimited at its periphery by the inner fastening line 108 defined by the holes 110 of the base 90 overmolded by the cap 95.

Each spillway 130 is configured to convey the cosmetic product from the dispense orifice 104 to the associated outlet orifice 125.

Since the inner fastening lines 108 do not overlap, each spillway 130 is hermetically separated from each other.

For example, each spillway 130 is in the form of a gutter in which the associated outlet orifice 125 is located at a top of the gutter. The lid 37 is removably mounted over the cap 95. The lid 37 avoids the outlet orifices 125 being exposed when the storage and dispensing device is not used.

A method for dispensing cosmetic products stored in the storage and dispensing device 10 will now be described.

Initially, the storage and dispensing device 10 stores two cosmetic products in the inner volumes 50. The intermediate chambers 20 are at least partially empty. The skirt 30 is in the rest position and each deformable region 123 of the cap 95 is in the rest configuration, correspondingly applied against the bearing surface of the base 90.

Thus, the cosmetic products are tightly preserved and separated from each other in each reservoir 15.

To use the storage and dispensing device 10, the user removes the lid 37.

During a filling step, each intermediate chamber 20 is filled with the cosmetic product stored in the reservoir 15 associated with the intermediate chamber 20. For example, the user flips the storage and dispensing device 10 overs or/and shakes it. The cosmetic product stored in the inner volume 50 is then stirred and enters the intermediate chamber 20 through the apertures 65.

Upon completion of the filling step, each intermediate chamber 20 contains a cosmetic product, preferably is filled with a cosmetic product.

Then, during a pressurization step, the user actuates the pressurization ember 30. For this purpose, the user presses the skirt 30 between his/her fingers to make it switch from its rest position into its dispense position. Thus, he/she brings the sidewalls 75 towards one another by deforming them.

The skirt 30 then presses, advantageously via its inner projections (not shown), on the reservoirs 15, advantageously via the bulges 55. The reservoirs 15 are compressed and the pressure in the inner volumes 50 increases. The increase in the pressure in the inner volumes 50 induces a pressurization of the intermediate chambers 20.

During a dispense step concomitant with the pressurization step, the cosmetic products simultaneously flow, from their intermediate chamber 20 in the associated dip tube 85, up to the proximal end 105 of the tube 85.

By the effect of the pressure of the cosmetic product through the dispense orifice 104 at the proximal end 105, each deformable region 123 of the cap 95 is deformed so as to switch from its rest position into its dispense configuration. The spillway 130 is formed between the deformable region 123 and the base 90, in which the cosmetic product flows until reaching the outlet orifice 125.

Each cosmetic product then flows over the outer face 120 of the cap 95. The user applies the outer face 120 against a body surface. This application ensures an extemporaneous mixing of the two cosmetic products on contact with the body of the user. The two cosmetic products react when they are mixed, forming for example a solid compound in the sweat pores of the user, thereby preventing him/her from sweating.

When the intermediate chambers 20 are empty or when the user stops pressing on the skirt 30, each deformable region 123 of the cap 95 returns back to its rest configuration.

The inner face 115 returns in contact against the bearing surface 106 and tightly seals the dispense orifice 104 at each proximal end 105 of a dip tube 85. Hence, each spillway 130 is tightly closed by the spontaneous elastic return of the deformable portion 123 against the bearing surface 106.

Hence, the excess cosmetic product possibly present in each spillway 130 is advantageously expelled through the outlet orifices 125 and/or partly returns in the dip tubes 85.

In this manner, no cosmetic product therefore remains stored in a portion in contact with air external to the storage and dispensing device 10, upstream of the outlet orifice 125. Hence, the formation of a solidified and/or degraded product residue after dispensing is completely prevented or very limited, which enhances comfort of the user.

When the user stops pressing on the skirt 30, the skirt 30 returns to the rest configuration.

Optionally, the user repositions the lid 37 over the cap 95.

The storage and dispensing device 10 according to the invention is very practical to use. One single press is required to simultaneously dispense at least two cosmetic products.

Furthermore, in the particular case where the displaced volume in each reservoir 15 by the press on the skirt 30 is substantially larger than the volume of the intermediate chambers 20, the amount of cosmetic product dispensed from each reservoir 15 depends on the dimension of each intermediate chamber 20. Thus, when the intermediate chambers 20 are identical, the same amount of each of the cosmetic products is dispensed, without the user having to control this amount.

In this particular case, a different proportion between each of the two cosmetic products could be obtained if the intermediate chambers have different dimensions.

In a more general case, the displaced volume in each reservoir 15 by the press on the skirt 30 is smaller than the volume of the intermediate chambers 20 (corresponding to a partial emptying of the intermediate chambers 20 by the effect of the press on the skirt 30). In this case, the dosage of the amount of product coming out of each of the reservoirs 15 is substantially identical.

In the case where it is desired to vary the proportion of one product relative to the other, it is for example possible to tune the sizing of the bearing areas 55, to cause a different deformation of the reservoirs 15. This could be achieved by creating a delay or by favoring pressing on one reservoir 15 rather than the other to obtain a different dose.

Thus, the storage and dispensing device 10 is adaptable to the desired composition of the mixture of the two cosmetic products.

In any case, an air intake occurs in the reservoirs 15 after dispensing by pressing on the skirt 30. For example, this air intake is done via the dispense orifices 125, through the same way as that by which the products are dispensed. Alternatively, the reservoirs 15 are airless reservoirs, such as “bag in bottle” reservoirs formed for example by a flexible bag containing the product, the flexible bag being received in a more rigid flask. The flexible bag is compressed as the product contained therein is dispensed.

In a variant that is not shown, the deformable region 123 is located on the base 90 and not on the cap 95. At least one region of the cap 95 opposite to the deformable region 123 located on the base 90 is then rigid. Like before, in the rest configuration, the deformable region 123 is arranged bearing on an opposite region of the cap 95 at least at the periphery of the dispense orifice 104. In the product dispense configuration, the deformable region 123 is deformed by the product coming out of the dispense orifice 104, at least one spillway 130 being formed between the cap 95 and the deformable region 123 up to the outlet orifice 125.

Still alternatively, each of the base 90 and of the cap 95 has a deformable region 123, the deformable regions 123 being applied against one another in the rest configuration, the deformable regions 123 being deformed by the product coming out of the dispense orifice to form a spillway 130 between the deformable regions 123 up to the outlet orifice
