Description

Title of the invention: Cosmetic product dispenser jar comprising a refill with a removable cap. Technical field of the invention

[0001] The invention relates to a refill for a cosmetic product dispenser jar, such as skincare cream or makeup powder.

[0002] In this case, the jar includes a base that receives the refill containing the cosmetic product. When the refill is empty, it is simply removed and a new one placed in the base.

[0003] This pot is stackable with other pots, in order to be easily transportable. Technical background

[0004] We are familiar with cosmetic product dispenser jars, comprising a base that receives a refill containing a cosmetic product. These jars are closed with lids. These jars are refillable. Indeed, when the refill is empty, it is replaced by another refill filled with a cosmetic product. This allows the jar and its lid to be preserved, as they are generally more robust than the refill and have an aesthetically pleasing shape.

[0005] Refills are generally sealed with a cap that the user opens upon first use. The user then dispenses a dose of product directly from inside the refill with their fingers. The product is thus in direct contact with the ambient air and with the user's fingers. The product risks being contaminated by bacteria present in the environment or on the user's finger. Summary of the invention

[0006] The present invention aims to overcome the various drawbacks mentioned above, by means of a cosmetic product dispenser jar that holds a refill equipped with dispensing means allowing the user to take a dose of product without putting their fingers directly inside the refill, and with hygiene management during refill replacement. This jar must be easily refillable, easily transportable, and easily stackable with other identical jars.

[0007] This objective is achieved by means of a refill for a cosmetic product dispenser jar, said refill comprising a hollow cylindrical body, a peripheral wall of which partially defines a chamber for conditioning the cosmetic product, said chamber having a variable volume and also being defined by an upper wall of the body and a lower wall movable in translation relative to the body, said movable lower wall consisting of a piston in sealed contact with an internal surface of the body and movable inside the body so as to vary the volume of the chamber, said upper wall having a product distribution orifice.

[0008] This refill is characterized primarily in that it also includes a cap for closing the distribution orifice, said cap having first means for removable attachment to the upper wall, as well as second means for attachment to cooperate with a lid of the pot.

[0009] The main idea of ​​this invention is to provide a completely closed refill, which is equipped with a distribution orifice.

[0010] This refill incorporates a pumpless dispensing device, in this case with a piston, to dispense doses of product through the dispensing orifice.

[0011] Since the dispensing orifice belongs to the refill, this means that with each refill change, a new, clean dispensing orifice is integrated into the pot. This contributes to optimizing the hygiene of the pot.

[0012] This opening is sealed by a cap. This cap is removed when the user wishes to retrieve a dose of the product.

[0013] Outside of dispensing times, the product contained in the refill is always protected from the external environment by the cap, and the risk of contamination is greatly reduced.

[0014] The cap belongs to the refill and thus has first removable fastening means for mounting it on the upper wall of the refill to close the dispensing opening. In addition, the cap has second removable fastening means for mounting it on a lid of the container. This is particularly advantageous because the cap can thus be attached to two different parts simultaneously. This dual fastening will be explained later in the description.

[0015] According to the different embodiments of the invention, which may be considered together or separately: - said upper wall is curved around the dispensing orifice to present a recovery area for the dispensed product. - the said first means of fixing the cap consist of a central sealing base penetrating inside the distribution orifice to close it. - the refill has an upper collar extending radially outwards, with at least two gripping tabs extending perpendicularly from this collar.

[0016] The invention also relates to a cosmetic product dispenser jar having a central X-axis and comprising:

[0017] - a base having a housing for a recharge according to one of the claims 1 to 4;

[0018] - the refill mounted inside the base, the refill being fitted with its cap;

[0019] - a tight-fitting lid for the pot, screwed onto a neck of the base,

[0020] This cover has an opening for receiving the refill cap, the cap having the second means for removable attachment to the cover.

[0021] As mentioned previously, there is a double hooking of the cap, both on the upper wall of the refill, and on the lid. This is particularly advantageous for the following reasons.

[0022] When the refill is first placed in the container, the lid has an empty opening. When the user screws on the lid, the cap falls into the opening and is held in place so that the cap is then attached to the lid. Thus, when the user unscrews the lid, the lid and cap assembly is moved away from the top wall of the refill, allowing the dispensing opening to be opened in a single motion, without needing to handle the cap and remove it after removing the lid.

[0023] The user can operate the dispenser to deliver one or more doses of product.

[0024] When he closes the jar with the lid fitted with the cap, the latter returns to the position of sealing the dispensing orifice, and the product contained in the refill is protected.

[0025] Thus, thanks to the double locking mechanism, the cap can protect the product in the refill before the first use, and then after each use, without the user having to handle it with their fingers. Hygiene is therefore further improved.

[0026] According to the different embodiments of the invention, which may be considered together or separately: - the cap is fitted into the opening of the lid by correspondence of shapes forming said second means of fixing, when screwing the lid onto the base. - the receiving orifice is open on both sides of an upper wall of the lid, for fitting the cap into the receiving orifice or for ejecting the cap from the receiving orifice. - the pot includes means for locking the refill in the base. - said locking means consist of a bayonet system located in the lower part of the pot. - said bayonet system consists of a first projection extending from an external surface of the reload body and cooperating with a second projection extending from an internal surface of the base. - said collar rests on an upper edge of the neck of the base when the refill is mounted in the base. - The base collar has notches to accommodate the gripping tabs of the refill. - Each gripping tab has a rib following the orientation of the thread of the tank neck. - the base has a bottom with a central window allowing access to the piston. - the base, the refill and the lid are made of the same material. - the base, the refill and the lid are made of plastic material, from polypropylene or polyethylene type. - the pot includes means for stacking with a base or lid of another pot. - the means for stacking the lid consist of an annular groove located in the upper part of a peripheral wall of the lid, said groove being able to cooperate with at least one protrusion provided for this purpose in the base of the other pot. - the base has means of stacking with a lid from another pot. - said means of stacking the base consist of at least one protrusion projecting from an inner surface of a lower outer skirt of the base, the protrusion being able to be fitted into a groove provided for this purpose in the lid of the other pot.

[0027] Finally, the invention relates to a method for recharging a pot as described above, comprising the following steps:

[0028] - separate the lid from the base, the cap being attached to the lid;

[0029] - remove the charger from the base by rotating the charger in the direction counterclockwise followed by an axial translational movement, the refill being without a cap;

[0030] - insert a new refill with its cap into the base by means of a axial translation movement followed by a clockwise rotation movement to lock the new reload in rotation in the base via a bayonet system;

[0031] - mount the cover onto the base by screwing it on, the cap of the new refill coming to exert pressure against the cap of the lid until it is ejected and comes to replace it in the receiving hole of the lid. Brief description of the figures

[0032] Other features and advantages of the invention will become apparent upon reading the detailed description that follows, for an understanding of which reference should be made to the accompanying drawings in which:

[0033] Fig. 1 is a general, perspective view of a pot according to the invention;

[0034] Fig.2 is a cross-sectional view of the pot according to Fig.1;

[0035] Fig. 3 is an exploded perspective view of the pot according to figures 1 and 2;

[0036] Fig. 4 is a perspective view of the lid;

[0037] Fig. 5 is a perspective view of the refill without the cap;

[0038] Fig. 6 is a perspective view of the base;

[0039] Fig. 7 is a cross-sectional view of the pot according to the preceding figures, stacked on a lid of another pot. Detailed description of the invention

[0040] By convention, the "axial" direction corresponds to that of principal extension of the receptacle, illustrated by the X axis on [Fig.1], and the "radial" direction is orthogonal to the axial direction.

[0041] In the detailed description of the figures that follows, the terms "upper" and "lower" or "top" and "bottom" shall be used without limitation with reference to the axial direction. Thus, the term "upper" refers to a part located near a lid 4 of the pot 1, and the term "lower" refers to a part located near a bottom of the pot 1.

[0042] 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.

[0043] The cosmetic product dispenser pot 1 shown in [Fig.1] is mainly made up of a base 3 inside which is inserted a refill 5, not visible, and a lid 4 which covers this base 3.

[0044] The refill 5 allows for the packaging of the cosmetic product. By cosmetic product, we mean a fluid product, such as foundation cream. By fluid product, we mean a product that is more or less viscous and not solid.

[0045] Fig. 2 is a cross-sectional view which this time allows visualization of the refill 5 arranged inside the pot 1.

[0046] This refill 5 is cylindrical of revolution, like all the parts forming part of the pot 1.

[0047] The cosmetic product is stored in a chamber 27 provided for this purpose in the refill 5.

[0048] Fig. 3 is an exploded view that allows visualization of all the parts belonging to the pot 1. In this case, there is the base 3, the lid 4, and the refill 5.

[0049] The refill 5 consists of a set of parts, namely a hollow cylindrical body 5 closed at the top by an upper wall 21, a cap 8, a piston 6, and a support plate 7 on the piston 6.

[0050] To deliver a dose of product contained in the refill 5, the user presses with his finger on the plate 7 of the piston 6 so as to create an overpressure in the chamber 27 to force the product out through a distribution orifice 26 provided on the upper wall 21.

[0051] There is therefore no pump in this pot 1, just manual means of distributing the cosmetic product.

[0052] The refill 5 itself, even without the base and the lid, allows doses of fluid product to be dispensed thanks to its piston 6 and its dispensing orifice 26. Outside of dispensing times, the cap 8 closes the dispensing orifice 26.

[0053] In particular, before the first use of the refill 5, the cap 8 seals the dispensing orifice 26. To allow the delivery of a dose of product, the cap 8 must be removed, the piston 6 activated, the product retrieved, and then the dispensing orifice 26 closed with the cap 8.

[0054] More precisely, the chamber 27 which contains the cosmetic product is delimited both by a peripheral wall 51 of the body 5, by the upper wall 21 of the body 5, and by the piston 6 in the lower part of the refill 5.

[0055] In the example shown, the upper wall 21 and the peripheral wall 51 are made of the same material and form a single piece, the body 5.

[0056] However, the upper wall 21 and the peripheral wall could consist of two different pieces joined together so as to form the body 5.

[0057] Body 5 is open at the bottom.

[0058] The piston 6 is disposed inside the body 5, passing through the opening formed in the lower part of the body 5. The piston 6 thus forms the bottom of the chamber 27.

[0059] The piston 6 conventionally comprises at least one annular lip 61,62 suitable for contacting the inner surface of the peripheral wall 51 of the body 5. In the present case, it comprises a first upper lip 61, and a second lower lip 62 located under the first lip 61.

[0060] These lips 61,62 make it possible to create a seal between the body 5 and the piston 6, so that there is no leakage of product under the piston 6.

[0061] The piston 6 is movable in translation, along the axis X, inside the body 5, so as to vary the volume of the chamber 27.

[0062] In [Fig. 2], the piston 6 is located at the lower end of the body 5, so the chamber volume is at its maximum. With each product dispensing, the piston 6 rises slightly within the body 5, thereby decreasing the volume of the chamber 27. The piston 6 thus rises inside until it comes to a stop against the upper wall 21 of the body 5, which means that the chamber 27 is empty of product.

[0063] Preferably, the piston 6 has a central support with a slightly convex shape, which conforms to the slightly convex inner shape of the upper wall 21 of the body 5, so that it can come to rest against this upper wall 21 with a flat contact, which means that all the cosmetic product has been dispensed. This avoids having dead volumes with residual product once the piston 6 has come to rest within the body 5.

[0064] The piston 6 has a thickened, and therefore reinforced, central part 64, which the user can press to raise the piston 6, and thus compress the chamber 27 to deliver a dose of product.

[0065] In order to have good contact between the user's finger and the piston 6, an optional support plate 7 is arranged under the central part of the piston 6.

[0066] This plate 7 can also present information on the formula of the cosmetic product or on the name of the product, or the brand name.

[0067] The upper wall 21 of the body 5 has the distribution orifice 26 at the level of its central area.

[0068] This upper wall 21 is slightly curved inwards towards the body 5, so as to define a basin 25 serving as a collection area for the dispensed product, which extends all around the dispensing orifice 26. This basin shape 25 allows the product to be held without overflowing from the upper wall 21. This also allows the user to more easily retrieve their dose of product with their finger by scraping this basin 25.

[0069] The distribution orifice 26 has a frustoconical shape in the upper wall 21.

[0070] This truncated conical shape allows for the accommodation of initial means for fixing the cap 8.

[0071] These first means of fixing the cap 8 consist of a central base 83 penetrating inside the distribution orifice 26 to close it.

[0072] This base 83 has an annular groove 82 into which an annular rib 29, provided for this purpose in the upper wall 21, penetrates, and which delimits the distribution orifice 26 at the end of the frustoconical zone. A contact is thus established watertight between the plug 8 and the upper wall 21, when the plug 8 is placed in the dispensing orifice 26.

[0073] The cap 8 also has second means of attachment which enable it to cooperate with the lid 4 of the pot 1, as will be explained later in the description.

[0074] The refill 5 as described above can be inserted inside the base 3.

[0075] Thus, base 3 has a housing into which the charging 5 is integrated.

[0076] More specifically, the base 3 has a cylindrical body 10 surmounted by a neck 35 onto which the cover 4 can be screwed.

[0077] The collar 35 defines an opening into which the refill 5 can be inserted.

[0078] The base 3 has a perforated base 33 with a central window 32 allowing the passage of central part 64 of piston 6 with its plate 7, so that the user has access to the plate 7 of piston 6 from the bottom 33 of pot 1.

[0079] The bottom 33 of the base 3 allows to hide and protect the lips 61,62 of the piston 6.

[0080] Preferably, the refill 5 has an upper collar 22 extending radially outwards. This collar 22 rests on the upper edge 37 of the neck 35 of the base 3 at the end of the insertion of the refill 5 into the base 3.

[0081] Thus, the refill 5 is suspended inside the base 3, and does not rest in the bottom 33 of the base 3. This makes it possible to overcome the differences in dimensions that there may be from one refill 5 to another, for example.

[0082] Advantageously, the pot 1 has means for locking the refill 5 in the base 3. Indeed, once the refill 5 is inserted into the base 3, it is preferable that it no longer move in rotation or axially, in particular when the user takes the dose of product and scrapes the upper wall 21 of the refill 5 with his finger.

[0083] These locking means consist of a bayonet system 52.30 located in the lower part of the pot 1.

[0084] More specifically, this bayonet system 52,30 consists of a first projection 52 extending from the external surface of the peripheral wall 51 of the body 5 of the reload 5, and cooperates with a second projection 30b extending from an internal surface of the body 5 of the base 3.

[0085] The first projection 52 is located in the lower part of the body 5 of the reload 5. Similarly, the second projection 30b is located in the lower part of the base 3, that is to say under the neck 35 of the base 3.

[0086] When installing the refill 5 in the base 3, the refill 5 is first inserted axially and then at the end of its axial travel, a slight rotation, preferably clockwise, is performed so that the first protrusion 52 comes into position under the second projection 30b, in a space 30c provided for this purpose. An axial blockage is then achieved.

[0087] The second projection 30b has an axial return 30d, which acts as a stop during the rotation of the reload 5 in the base 3, which makes it possible to stop the rotational movement of the reload 5 relative to the base 3.

[0088] In addition, the first projection 52 has a hollow 53 which cooperates with an axial protrusion 30a extending from the second projection 30b, allowing the passage of a hard point during the rotation of the reload 5 in the base 3. The passage of this hard point gives an indication to the user that the reload 5 is properly locked in position inside the base 3, with axial locking and rotational locking.

[0089] To remove the refill 5, the user turns the refill 5 counterclockwise, then removes the refill 5 axially.

[0090] To facilitate handling of the refill 5 when mounting it in the base 3 and when removing it from the base 3, the refill 5 has at least two gripping tabs 23 extending from the collar 22, perpendicularly.

[0091] To integrate harmoniously these gripping tabs 23 into the overall aesthetic appearance of the pot 1, the base 3 has notches 39 for receiving the gripping tabs 23 of the refill 5. These receiving notches 39 are cut into the neck 35 of the base 3. Thus the neck 35 of the base 3 has a discontinuous shape in its upper part.

[0092] During the rotation of the refill 5 in the base 3 for its placement, the tabs 23 gradually come into position in the notches 39. When passing the hard point, an end edge of each tab 23 can come to rest against an end edge delimiting the corresponding notch 39, so as to have a double locking in rotation of the refill 5 with respect to the base 3.

[0093] Once the refill 5 is placed in the base 3, the tabs 23 completely fill the notches 39, and the upper edge of the pot 1, without its lid 4, has a uniform and flat appearance.

[0094] For fixing the cover 4 to the base 3 by screwing, an external thread 36 is provided on the neck 35 of the base 3 and cooperates with an internal thread 42 provided on a peripheral wall 41 of the cover 4.

[0095] Optionally, the gripping tabs 23 of the refill 5 each have an external rib 24 which follows the orientation of the adjacent thread belonging to the external thread 36 of the neck 35 of the base 3. This makes it possible to replace the external thread 36 of the base 3 at the receiving notches 39 because they do not have one.

[0096] Thus, when the user screws the cover 4 onto the base 3, the internal thread 42 of the cover 4 cooperates both with the external thread 36 of the neck 35 of the base 3, and with the ribs 24 of the gripping tabs 23 of the refill 5.

[0097] The ribs 24 also allow for better gripping of the gripping tabs 23, with an anti-slip effect.

[0098] The lid 4 of the pot 1 has a main flat wall 43, perpendicular to the axis X, from which extends the peripheral wall 41 comprising the internal thread 42.

[0099] This main wall 43 has a receiving opening 44 for the cap 8 of the refill 5.

[0100] Thus when the user screws the cover 4 onto the base 3, the cap 8 arranged above the refill 5 is inserted into the receiving hole 44 of the cover 4.

[0101] Once the lid 4 is mounted on the base 3, it is no longer possible to remove the cap 8. This prevents any accidental dispensing of the product.

[0102] According to the invention, the cap 8 has second means of removable attachment to the cover 4. More precisely, the cap 8 is fitted into the receiving orifice 44 of the cover 4 by matching shapes, forming these second means of attachment.

[0103] More specifically, the cap 8 has an annular groove 81 into which an annular rib 46 provided for this purpose is inserted in the main wall 43 of the cover 4.

[0104] Thus, when the stopper 8 comes to rest in the receiving orifice 44, it fits into it, and remains trapped in the cover 4.

[0105] These second means of fixing the cap 8 to the lid 4 are more rigid than the first means of fixing the cap 8 to the upper wall 21 of the refill 5, so that when the lid 4 is removed, the cap 8 separates from the upper wall 21 of the refill 5, remaining fitted into the cap 8. Thus the cap 8, initially attached to the refill 5 before the first use of the refill 5, becomes attached to the lid 4 once the latter is screwed onto the base 3.

[0106] Preferably, the annular rib 46 of the cover 4 and the annular groove 81 of the cap 8 are crenellated, so as to block the cap 8 from rotating relative to the cover 4.

[0107] The receiving orifice 44 opens into the inside of the main wall 43 of the cover 4.

[0108] Thus, when the cover 4 is screwed onto the base 3 for the first time, the cap 8 of the refill 5 is inserted into the receiving opening 44 from the underside of the cover 4, in an upward-facing mounting direction. The cap 8 is then fixed to the cover 4 and is moved away from the refill 5 each time the user unscrews the cover 4, which opens the dispensing opening 26 so that the user can dispense the product. After each use, the cover 4 is put back in place on base 3, so that the base 83 of the cap 8 again enters the inside of the distribution orifice 26 to close it tightly.

[0109] Then, when refilling the container 1 when it is empty, the lid 4 is unscrewed along with the cap 8, the refill 5 without the cap 8 is removed from the base 3, and a new refill 5 with a new cap 8 is placed in the base 3. Then the lid 4 is screwed onto the base 3, and the new cap 8 presses against the old cap 8 in place in the lid 4, exerting pressure on the old cap 8 until it is ejected from the receiving opening 44 from the top of the lid 4, thanks to its open design. The new cap 8 then falls into place in the receiving opening 44, always in the same upward orientation.

[0110] Advantageously, when the cap 8 is in place in the lid 4, its upper surface is flush with the upper surface of the lid 4, for an optimal external aesthetic appearance, and to ultimately obtain a general upper surface of the pot 1 which is flat.

[0111] This is particularly advantageous insofar as this pot 1 is intended to be stacked with other identical pots 1.

[0112] To ensure such stacking, the lid 4 and the base 3 have stacking means, so that the base 3 of a first pot 1 can be fitted onto the lid 4 of a second pot 1, or that the lid 4 of the first pot 1 can be fitted onto the base 3 of a third pot 1.

[0113] To achieve this, the base 3 has a lower external skirt 31, which surrounds the body 10 of the base 3. A shoulder 38 is made between the neck 35 of the base 3 and this skirt 31. This shoulder 38 is dimensioned so as to be able to align the outer surface of the skirt 31 with the outer surface of the peripheral wall 41 of the lid 4, in order to have a pot 1 whose overall external appearance is relatively homogeneous.

[0114] The stacking means consist of: - an annular groove 45 of the cover 4 provided at its external junction between its peripheral wall 41 and its main wall 43, and - protuberances 34 regularly arranged at the level of the internal surface of the external skirt 31.

[0115] The protuberances 34 of the base 3 of an upper pot 1 fit elastically into the groove 45 of the lid 4 of a lower pot 1, so as to snap the base 3 into the lid 4.

[0116] The outer skirt 31 protrudes axially relative to the bottom 33 of the base 3, so as to create a free space inside which the main wall 43 of the lid 4 fitted with the cap 8 of the lower pot 1 can be housed.

[0117] Preferably, the lower perimeter of the peripheral wall 41 of the cover 4 has a plurality of hollows 46 intended to facilitate unscrewing the cover in the mold during its manufacture.

[0118] Preferably, the base 3, the refill 5, and the lid 4 are made of the same plastic material. This avoids the user having to sort the different parts of their pot 1, according to the materials, for disposal in different recycling bins.

[0119] The plastic material may be selected from polypropylene (PP), recycled polypropylene (R-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 material (PCR and / or a similar material). Preferably, it is recycled or non-recycled polypropylene and / or polyethylene terephthalate.

[0120] Thus, advantageously, the base 3, the refill 5, and the lid 4 are made of plastic material selected from polypropylene and / or polyethylene terephthalate.

[0121] The use of plastics, in particular similar plastics, for the entire container 1 facilitates recycling. In particular, polypropylene and polyethylene terephthalate are two plastics whose recycling cycle is well known.

[0122] Pot 1 can be produced by 3D printing.

[0123] In particular, the base 3, the refill 5, and the lid 4 can be produced by 3D printing. Such a printing process makes it possible, in particular, to create these parts with very free designs and shapes that contribute to the aesthetic appearance of the pot 1.

[0124] The configurations shown in the cited figures are only possible examples, in no way limiting, of the invention which on the contrary encompasses variants of forms and designs within the reach of the person skilled in the art.
