Description

Title of the invention: Refillable container for cosmetic products. Technical field of the invention

[0001] The present invention relates to packaging containing a cosmetic product. It applies in particular to a refillable container for a cosmetic product comprising an external container, an internal cup for receiving the cosmetic product mounted removably in the container, and a lid closing the container. Previous technique

[0002] It is known in the prior art to make rigid containers for cosmetic products, for example pasty or fluid creams for the face (or other types of commonly used cosmetics), comprising for this purpose an outer container, an inner cup containing the cosmetic product, and a lid for closing the container.

[0003] These extremely widespread containers, which are generally called jars and which are sold by the millions each year throughout the world, exist in all dimensions, rest on a flat bottom and often have a wide top opening so as to be able to easily retrieve the cosmetic product with an applicator (sponge, brush) or more often directly with the fingers of the user.

[0004] For ecological and circular economy reasons, it is increasingly common to use bio-based raw materials to make certain parts of these packages or to save raw materials.

[0005] To this end, it is often planned from the design stage that elements of the packaging, or even the entire package, should be removable (after use) for recycling. In particular, it has been proposed to create removable internal cups so that only this part of the packaging needs to be replaced, while the pot and / or lid can be kept, and these can themselves eventually (at the end of their life) be recycled separately.

[0006] Systems have therefore been invented to removably connect the inner cup to the outer casing. Numerous patents and a substantial body of literature exist on this subject. For example, documents FR2004647A1, EP2308339B1, EP2892385B1, FR3071388A1, and FR3056087B1 can be cited, in which the inner cup is generally mounted (clipped, screwed) in a removable manner on the upper rim of the outer casing and sometimes inside the casing (peripheral side wall), or even at the bottom of the casing.

[0007] However, the solutions currently implemented are still too complex (shape of the parts), sometimes fragile or impractical for the consumer to use (difficulties in assembling / disassembling the internal cup of the external pot).

[0008] Furthermore, these systems are not very modular, making it difficult to mix materials to create the different elements. Prior art pots are therefore not very "customizable" and all look more or less alike. Presentation of the invention

[0009] The present invention aims to remedy these drawbacks with a totally innovative approach allowing significant modularity (in particular shapes and materials), an eco-responsible design and great ease of use.

[0010] To this end, according to a first aspect, the present invention relates to a refillable container for cosmetic products comprising at least: - an external casing pot having a side wall, for example cylindrical, a top neck and a bottom opening, - a removable inner cup intended to be inserted into said jar and having an upper receptacle for cosmetic product and a lower connecting barrel, and - a lid intended to close the container, characterized in that it further comprises a detachable intermediate ring provided with a first removable attachment means to said bottom opening of the external dressing jar and a second removable attachment means to the lower connecting barrel of the inner cup, so that the jar, the lid, the cup and the ring are independent of each other.

[0011] The invention is implemented according to the embodiments and variants set out below, which are to be considered individually or according to any technically operative combination.

[0012] Advantageously, the first removable attachment means comprises a radial hook elastically deformable towards the inside of the ring and cooperating with a rim of the bottom opening of the external dressing pot to form a mechanical linking clip.

[0013] Preferably, the second removable attachment means comprises a radial hook elastically deformable outwards from the ring and cooperating with a prominent cord projecting from an external peripheral surface of the connecting shaft of the internal cup to form a mechanical connecting clip.

[0014] According to one design variant, the second removable attachment means comprises a radial hook elastically deformable towards the inside of the ring and cooperating with a prominent cord protruding from an internal peripheral surface of the connecting shaft of the internal cup to form a mechanical connecting clip.

[0015] According to a preferred embodiment, the first and second removable attachment means are concentric, the first means being external to the second means.

[0016] According to a particular embodiment of the present invention, at least one of the first and second removable attachment means comprises a single continuous hook.

[0017] According to one design variant, at least one of the first and second removable attachment means comprises a series of hooks separated from each other.

[0018] According to a particularly interesting aspect of the present invention, the ring is annular with a circular cross-section.

[0019] According to a complementary feature, the external dressing pot is provided, at the level of its neck, with an external screw thread cooperating with an internal screw thread of the lid.

[0020] Advantageously, the outer dressing pot and / or the lid and / or the inner cup is / are made of one or more of the following materials chosen from wood, a metal, glass, a mineral material, a plastic material, for example bio-based, or a ceramic. Brief description of the figures

[0021] Other advantages, purposes and features of the present invention will become apparent from the following description, given for explanatory purposes and in no way as a limitation, with reference to the accompanying drawings, in which:

[0028] [Fig.7] [Fig.7] is a cross-sectional perspective view of a variant of Figures 1 to 6. Description of the implementation methods

[0029] As illustrated in Figures 1 to 6, the present invention relates to a refillable container 1 for cosmetic products, for example for fluid cream.

[0030] This container comprises an external dressing pot 10, an internal cup 20 provided with a wide upper opening, a closing lid 30 of the pot and a lower intermediate connecting ring 40.

[0031] The external dressing pot 10 has a side wall 11, for example cylindrical, a top neck 12 with an external thread 13, and an opening 14 provided in the bottom 15.

[0032] The removable inner cup 20 is intended to contain the cosmetic product and is inserted into the outer pot 10. It has a wall 21, an upper rim 22 which rests on the neck 12 of the outer dressing pot 10, and a hollow upper receptacle 23 for cosmetic product extending into a lower connecting barrel 25.

[0033] The lid 30 serves to close the container 1 and is screwed onto the neck 11 of the external dressing pot 10 by means of respective means consisting of an internal thread 33 of said lid 30 and an external thread 13 of said pot 10.

[0034] The lower intermediate ring 40 is removably fixed to the bottom 15 of the external dressing pot 10, and the internal cup 20 is removably fixed to said intermediate ring 40 via the lower connecting barrel 25.

[0035] For this purpose, the intermediate ring 40, generally in the form of a flat ring with a circular cross-section, is provided with a first removable attachment means 42 to an opening 16 of the bottom 15 of the external dressing pot 10 and a second removable attachment means 44 to the lower connecting shaft 25 of the internal cup 20, so that the pot 10, the lid 30, the cup 20 and the ring 40 are totally independent of each other (see figures 1 to 3).

[0036] The outer casing pot 10 and / or the lid 30 and / or the cup 20 is / are made of one or more of the following materials selected from wood, metal (aluminum, brass, stainless steel, Zamak), glass, a mineral material (ceramic), a plastic material, for example bio-based, or ceramic. The intermediate connecting ring 40 is preferably made of recyclable and / or bio-based plastic. Various manufacturing technologies can be used to produce these parts, such as blow molding, injection molding, machining, additive manufacturing, stamping, etc. It is therefore possible to consider multiple material combinations, for example, a transparent molded glass pot, a cup made of plastic, wood, ceramic, or metal, and a plastic lid.

[0037] More specifically, the first removable attachment means 42 consists of an annular lip provided with a radial hook 43 elastically deformable towards the interior of the intermediate ring 40 cooperating with a rim 16 of the bottom opening 14 15 of the dressing pot 10 to form a mechanical linking clip that can be operated manually or mechanically.

[0038] Similarly, the second removable attachment means 44 is composed of an annular lip provided with a radial hook 45 elastically deformable outwards from the intermediate ring 40 and cooperating with a cord 26 projecting from an external peripheral surface of the connecting shaft 25 of the internal cup 20 to form a mechanical connecting clip that can be manipulated manually or mechanically.

[0039] As illustrated, the annular lips forming hooks 43 and 45 are concentric and separated by a void area 46 allowing their elastic radial deformation.

[0040] According to an alternative design illustrated in [Fig. 7], the second removable attachment means comprises 44 a radial hook 45a elastically deformable towards the inside of the ring and cooperating with a cord 26a projecting from an internal peripheral surface of the connecting shaft 25b of the internal cup 20 to form a mechanical connecting clip. In this case, the shaft, consisting of a thin annular wall with a circular cross-section, is sandwiched between the first external hook 43 and the second internal hook 45a.

[0041] In all the illustrated cases, the connection between the elements considered is achieved by axially pressing the lower intermediate ring 40 onto the base 15 of the external housing 10 and the internal cup 20 onto the lower intermediate ring 40, or of said intermediate ring 40 onto the internal cup 20 and then of this assembly onto the base 15 of the housing 10, without rotational connection or bayonet-type notch. The axial retention of the elements in position relative to each other is thus achieved by the radial force produced by the hooks, respectively outwards for the base 15 of the housing 10 and inwards or outwards (depending on the embodiment) for the shaft 25 of the cup 20, so as to prevent unintentional axial separation of said elements.

[0042] It must be clearly understood that the detailed description of the object of the Invention, given solely by way of illustration, does not in any way constitute a limitation, technical equivalents also being included in the scope of the present invention.

[0043] Thus, the general shape of the pot or cup can vary, as well as the respective dimensions (height, diameter) or the contents (powder for example), provided that the basic principle of using a removable intermediate connecting ring is retained.
