Description

Technical Field

[0001] This invention relates to the field of devices for packaging, applying and / or dispensing products, particularly cosmetic products, and more particularly to the field of devices having a product refiller. Background Technology

[0002] Proposing eco-responsible and environmentally friendly solutions that take into account environmental issues in their design and development has become a major focus in addressing global challenges.

[0003] Therefore, in order to reduce the carbon footprint of products, it has proven crucial to design products that enable the reduction of the amount of materials used and / or the replacement with more environmentally friendly materials and / or the use of recyclable materials.

[0004] In this context, it is important to develop packaging that generates less waste and is optimized, particularly for the volume of the products being transported, especially by redesigning and / or adjusting its dimensions to reduce the amount of packaging in terms of volume and weight.

[0005] The aim is to propose reusable, eco-responsible containers, especially those that can be refilled at home or in a store, in order to reduce the carbon footprint of packaging.

[0006] To reduce the manufacturing costs of cosmetic packaging and minimize environmental impact, devices have been developed for packaging, applying, and / or dispensing products, particularly cosmetic products, which include a product refiller and a housing for receiving the refiller. In this approach, issues arise regarding the configuration of the device to allow for replacement of the product refiller, and the retention of the refiller within the housing during use, particularly depending on the type of product contained within it.

[0007] There is a growing need to gradually replace existing packaging with refillable packaging, application, and / or dispensing devices. This allows the casing to be retained once the cosmetic product has been used, and only the refiller needs to be discarded. Once the refiller is empty, all the user needs to do is remove it to replace it with a new or different refiller.

[0008] In this context, it is important that the packaging, application, and / or dispensing device has the aesthetic qualities required by the user, is as easy and efficient to use as a device without a refiller, and that the operation of replacing the used refiller is as simple as possible for the user, requiring minimal effort or attention.

[0009] Therefore, the packaging device must allow the refiller to be reliably held in the housing during its use.

[0010] Many forms of this type of device have been proposed.

[0011] In particular, a pipette packaging and dispensing device is known from utility model CN214931380U and international application WO9947262A1. This device has a ring for holding a refiller in a housing. After the refiller is inserted, the ring is tightened or snapped onto the housing to abut against the edge of the refiller and thus prevent it from being pulled out. Removing the refiller requires many steps and numerous manipulations, making this change cumbersome.

[0012] In particular, a packaging and dispensing device is known from patent application FR3126287A1, which has a system for holding a refiller in a suitable position within a housing by means of a friction member configured to prevent the refiller from exiting the housing under its own weight by friction against the outer wall of the refiller. This system is described in particular with respect to a pump dispensing device that makes it possible to dispense the product by pressure without rotating the device.

[0013] This type of system does not allow the refiller to be effectively and continuously held in the housing, especially if the refiller has a cap designed to be screwed onto or unscrewed from the refiller body while it is held in place by the housing. During manipulation of the refiller or cap for dispensing or applying product, the transmission of torque between the refiller and the housing can cause the refiller to be pulled out during manipulation or prevent effective manipulation of the refiller, particularly its cap, to be ineffective in opening the refiller. For example, the refiller may rotate with the cap while attempting to open it by twisting. This can complicate the use of a refiller housed in the housing and prevent its easy opening.

[0014] To remedy the latter drawback, one solution could be to increase the interference between the friction member and the outer wall of the refiller, thereby generating an increased drag torque at the point of interference between the friction member and the refiller; however, this increase would have adverse effects, making it difficult to axially introduce the refiller into the housing and difficult to pull the refiller out of the housing, and thus making these operations cumbersome for the user.

[0015] There is a need to benefit from packaging, application, and / or dispensing devices equipped with cosmetic product refillers that encourage the retention of the casing for reuse with new refillers, while remaining attractive to consumers.

[0016] There is also a need to improve packaging, application, and / or dispensing devices with product refillers by proposing a solution that allows the refiller to be reliably held in the housing in both translational and rotational aspects, so as to improve the use of these devices and make them easy and pleasant for users to use.

[0017] Finally, there is a need for a packaging, application, and / or dispensing device that provides a user experience that meets the user's requirements for dispensing and / or applying products, particularly cosmetic products, so that the quality of the device can be perceived by the user. Summary of the Invention

[0018] The present invention aims to meet this need, and it achieves this by providing a device for packaging, applying, and / or dispensing cosmetic refillers, the device having: A cosmetic refiller, extending along a longitudinal axis, has the following features: The refiller body, which at least partially defines the cosmetic product reservoir, and The cap is used to seal the refiller body. The refiller body has an outer surface having at least one first protrusion / recess. A housing having an outer shell for receiving a cosmetic refiller, the housing having an inner surface having at least one second protrusion arranged to prevent the cosmetic refiller from rotating about its longitudinal axis within the housing by cooperating with the at least one first protrusion when the cosmetic refiller is in the housing.

[0019] "Preventing rotation" is understood to mean that when the first and second concave-convex parts cooperate to engage, the refiller cannot rotate within the housing relative to the housing, particularly about the longitudinal axis.

[0020] As explained above, the fact that the refiller is essentially removable from the shell makes it possible to reduce the manufacturing cost of cosmetic packaging and to reduce the environmental impact of packaging, application and / or dispensing devices by allowing the shell to be retained and only the shell to be replaced when the cosmetic product in the refiller's reservoir is depleted.

[0021] This also makes it possible to easily replace the product contained in the housing by simply changing the refiller.

[0022] Once the refiller is empty, or even before that, all the user needs to do is remove the refiller so that it can be replaced with a new or different refiller.

[0023] The presence of the first and second protrusions arranged to cooperate in order to prevent the refiller from rotating within the housing makes it possible to prevent the refiller from rotating relative to the housing when a rotational torque is applied to the refiller, especially when the user rotates the closure cap.

[0024] Refiller The refiller body may be elongated along the longitudinal axis. The refiller body may also have at least one portion for insertion into a housing.

[0025] The refiller body may have (particularly along the longitudinal axis) a product reservoir and a portion for dispensing cosmetic products. The dispensing portion may be specifically configured to extend out of the housing when the refiller is inserted into the housing, having an outwardly facing opening and a receiving cap.

[0026] Product storage containers can be cylindrical in shape, especially rotating cylindrical in shape. The main axis of the cylinder is, in particular, the longitudinal axis.

[0027] The part used to dispense cosmetic products can be cylindrical, especially a rotating cylinder, with the main axis of the cylinder being the longitudinal axis.

[0028] Preferably, the maximum width (especially the diameter) of the product reservoir in the transverse section is greater than the maximum width (especially the diameter) of the portion used to dispense the cosmetic product in the transverse section.

[0029] The refiller body may have (particularly along the longitudinal axis) a widened portion between the reservoir and the dispensing section for securing to the housing, the widened portion having a first protrusion / recess on its outer surface. The maximum lateral dimension of the widened portion is greater than the maximum lateral dimension of the reservoir, which in particular makes it easier to insert the refiller reservoir into the housing housing while maintaining an optimal product quantity in the reservoir.

[0030] The product storage unit can be connected to the widened retaining section via the shoulder.

[0031] The refiller body may have a base between the widened retaining portion and the product dispensing portion, the base being configured to face the housing. The base may be connected to the widened retaining portion via a shoulder. The base may be connected to the dispensing portion via a flat surface substantially transverse to the longitudinal axis of the refiller body. Such a base improves the retention of the refiller in place within the housing. The shoulder further improves the positioning and retention of the refiller, especially considering manufacturing tolerances.

[0032] Preferably, the refiller body is a single piece. In variations, the refiller body may have multiple blocks that are separate or fastened to each other by any suitable method (e.g., adhesive bonding).

[0033] The refiller body may have an upper end arranged to receive a cap. The upper end may have an opening to allow access to the product. The refiller may have an impregnation element that is fastened to or integral with the surface of the cap inside the refiller and configured to extend into the refiller body when the cap is on it, particularly through the opening, all the way to the reservoir. The impregnation element may be an applicator component, particularly for applicators of eyeliner, liquid lipstick, lip gloss, care products, or mascara, or a pipette. The impregnation element may be connected directly to the cap or via a rod. The presence of the impregnation element particularly makes it easier to reach the bottom of the refiller and thus recover the maximum amount of product.

[0034] The sealing cap can be screwed onto the refiller body. The sealing cap specifically makes it possible to maintain a seal between the refiller and the product. It also allows for better handling of the refiller, limiting the risk of product overflow or spillage, even if the user improperly places the refiller in the housing. The fact that the first and second protrusions prevent rotation of the refiller within the housing makes it possible, with the threaded cap, to prevent rotation of the refiller within the housing during tightening or loosening of the cap, which involves applying a rotational torque about the longitudinal axis to the refiller.

[0035] Refillers can be used with cosmetic products, especially eyeliner, liquid lipstick, lip gloss, skincare products, or mascara.

[0036] Preferably, the refiller body is made of recyclable materials, particularly recyclable plastic materials, especially polyethylene terephthalate (PET), polyethylene (PE), or polypropylene (PP), which may be virgin or recycled. The refiller body may also be made of glass or cellulose materials.

[0037] case The housing may have an upper surface arranged to receive a base for the refiller body, which is specifically arranged in a recess.

[0038] The housing can extend along the longitudinal axis, and is particularly elongated. When the refiller is in the housing, the longitudinal axis of the refiller body and the longitudinal axis of the housing can coincide.

[0039] The housing may have a housing body and an upper connecting portion, the housing body being configured to receive a reservoir of the refiller when the refiller is inserted into the housing, the upper connecting portion being specifically attached to the housing body, wherein the refiller body has a second protrusion on a surface on the inner side of the connecting portion.

[0040] The upper portion for connection with the refiller body may be a ring attached to the body of the housing, inserted between the housing body and the refiller. The ring can be fastened to the housing by any means, particularly by screwing or snapping, or by adhesively attaching it to the neck of the housing body. The housing may have a mechanism for preventing rotation of the intermediate ring relative to the housing body. The rotation prevention mechanism may have multiple protrusions that cooperate with multiple recesses in the housing body (particularly in the neck of the housing body). This rotation prevention mechanism specifically prevents movement of the ring relative to the housing body, particularly during insertion and manipulation of the refiller. The ring may have connectors and caps fastened to each other. While improving the aesthetic appearance of the device, the caps may also make it possible to restrict access to the first and second protrusions, for example, by being made of a metallic material such as aluminum or a plastic material with, for example, a metallized coating. The connectors may be made of a material with a certain degree of elasticity, particularly an elastomeric material. Preferably, the connector can be made of a plastic material, such as polypropylene (PP), polyethylene terephthalate (PET), or PBT, which has a certain rigidity and a controlled coefficient of friction that is advantageous for matching the constituent materials of the refiller body. In a variant, the ring is one-piece and is specifically made of polypropylene (PP), polyethylene terephthalate (PET), or polybutylene terephthalate (PBT).

[0041] In the variant, the upper portion used to connect with the refiller body is a single piece with the housing body.

[0042] Preferably, the body of the housing is made of glass. The use of mineral glass provides durability and allows for possible recycling or reuse without concern for the deterioration of its aesthetic appearance, as glass is a durable and strong material that is particularly resistant to scratches. Furthermore, glass can be easily cleaned if appropriate. Glass also provides effective protection against UV radiation, lateral and axial mechanical stress, and provides a cool feel to the housing, which is pleasant during handling operations.

[0043] First concave-convex portion and second concave-convex portion The first protrusion may extend on the widened portion of the refiller body. One of the first and second protrusions (preferably the second protrusion) is a protruding protrusion, and the other of the first and second protrusions (preferably the first protrusion) is a recessed protrusion having a particularly complementary shape.

[0044] The recessed or uneven part can be a groove, a flat part, or a snap-fit ​​fastening part.

[0045] The protruding protrusions or recesses can be ribs, pins, or any other elements used to cooperate with the aforementioned recessed protrusions or recesses.

[0046] Preferably, the first and second protrusions are configured to cooperate by translating along the longitudinal axis of the housing after orientation, or in other words, after the refiller and housing are angularly rotated about the longitudinal axis, such that the first and second protrusions face each other during insertion.

[0047] One of the first and second protrusions (preferably the first protrusion) is a flat portion, and the other of the first and second protrusions (preferably the second protrusion) has a flat surface. When the refiller is in the housing, the flat portion contacts the flat surface via at least a portion of its surface to form a stop that resists rotation of the refiller relative to the housing about the longitudinal axis in both rotational directions about the longitudinal axis.

[0048] Preferably, the first protrusion (particularly the flat portion) may have a plane inclined relative to the longitudinal axis of the refiller, which is further away from the longitudinal axis, particularly on the cap side than on the reservoir side, forming a non-zero angle with the longitudinal axis when the cosmetic refiller is inserted into the housing, for example, strictly greater than 0°, more preferably greater than or equal to 1°, even more preferably greater than or equal to 2°, preferably greater than or equal to 3°, and / or less than or equal to 20°, more preferably less than or equal to 10°, preferably less than or equal to 5°, for example, substantially equal to 3.5°. Preferably, the maximum lateral dimension of the retaining portion is greater than the minimum internal lateral dimension of the connecting portion. This inclination and this difference in size allow the refiller to be retained on the housing at both the connecting and retaining portions. Furthermore, such inclination represents a good trade-off between the aesthetics of the product and the effectiveness of retaining the refiller in a proper position within the housing.

[0049] Furthermore, the first protrusion (particularly the flat portion) may have a plane inclined relative to the plane of the second protrusion that contacts it, this plane being further away from the plane of the second protrusion, particularly on the cap side than on the reservoir side, forming a non-zero angle with the longitudinal axis when the cosmetic refiller is inserted into the housing, for example, strictly greater than 0°, better greater than or equal to 1°, even better greater than or equal to 2°, preferably greater than or equal to 3°, and / or less than or equal to 20°, better less than or equal to 10°, preferably less than or equal to 5°, for example, substantially equal to 3.5°. This inclination facilitates insertion by translational movement along the longitudinal axis of the housing. This inclination also makes it possible to adjust the contact between the refiller and the housing to eliminate clearance that may exist in the radial direction due to manufacturing tolerances. It also helps to hold the refiller to the housing.

[0050] In the variant, when the cosmetic refiller is inserted into the housing, the flat portion can be parallel to the flat surface.

[0051] The second concave-convex portion may also have a plane that is inclined relative to the longitudinal axis.

[0052] When the surface is cylindrical, the flat portion can have a maximum depth between 1% and 15%, particularly between 2% and 10%, of the outer diameter of the outer surface of the refiller body on which the flat portion is formed.

[0053] The flat portion and the flat surface can have the same angular range. In variations, the flat portion and the flat surface can have different angular ranges, and in particular, the flat portion can have a larger angular range than the flat surface.

[0054] The first and / or second protrusions (particularly the flat portion) may have rounded or chamfered corners at their insertion edges (particularly the upper edge of the second protrusion or the lower edge of the first protrusion). The rounded or chamfered corners facilitate the insertion of the refiller into the housing.

[0055] In the variation, the flat part may not have rounded corners or chamfers.

[0056] The device may have a plurality of first and second protrusions, particularly an even number of first and second protrusions, such as two first and second protrusions, which are arranged in an opposing manner, particularly about the longitudinal axis and diametrically opposite to each other, so as to cooperate with each other when the cosmetic refiller is in the housing in order to prevent the cosmetic refiller from rotating about the longitudinal axis in the housing.

[0057] In the case of an even number of complementary protrusions and recesses, the protrusions and recesses are preferably arranged in pairs opposite to each other.

[0058] The first and second protrusions are preferably regularly distributed around the longitudinal axis, and in particular, in the case of both, they are distributed diametrically opposite to each other on the outer surface of the refiller and the inner surface of the housing, respectively.

[0059] The first and second concave portions may have a height measured along the longitudinal axis that is the same as, in particular substantially equal to, the height of the retaining portion of the refiller, particularly between 2 mm and 20 mm, particularly between 5 mm and 15 mm, for example about 10 mm.

[0060] In a variation, the first and second protrusions may have different heights measured along the longitudinal axis. Specifically, the first protrusion may have a height measured along the longitudinal axis that is greater than the height of the second protrusion measured along the longitudinal axis.

[0061] For example, the first concave-convex portion may have a height between 2 mm and 20 mm, particularly between 5 mm and 15 mm, measured along the longitudinal axis, for example about 11 mm, and the second concave-convex portion may have a height between 1.5 mm and 18 mm, particularly between 3 mm and 14 mm, measured along the longitudinal axis, for example about 9 mm.

[0062] The first concave and convex portion may extend over an angular range between 10° and 70°, particularly between 40° and 60° (e.g., 55°).

[0063] The second concave and convex portion can extend over an angle range between 10° and 60°, particularly between 35° and 55° (e.g., 50°).

[0064] Friction elements Furthermore, the device may have at least one friction element, more preferably multiple friction elements, which extend between the refiller body and the housing when the refiller is inserted into the housing, and are configured to hold the refiller body in the housing by friction. One or more friction elements may each be a protrusion or recess protruding in the radial direction from the inner surface of the housing, particularly from the connecting portion, or from the outer surface of the refiller body, particularly from the widened holding portion. Preferably, one or more friction elements are protrusions or recesses protruding from the inner surface of the housing, particularly from the connecting portion. This particularly makes it possible to reduce the material required to manufacture the refiller, and thus reduce the amount of material discarded each time the refiller is replaced.

[0065] When the refiller is inserted into the housing, one or more friction elements are preferably separated from the first and second protrusions, particularly extending on the angular portions of the device surrounding the longitudinal axis, separated from the angular portions of the first and second protrusions, each angular portion possibly lacking the first and second protrusions. Furthermore, each angular portion may have at least one, preferably at least two, and more preferably at least three friction elements. The friction elements may be regularly distributed in each angular portion lacking the first and second protrusions. One or more friction elements may each be a protrusion protruding from the inner surface of the housing or from the outer surface of the refiller body.

[0066] Preferably, the refiller body and housing may have a plurality of first and second protrusions. When the refiller is in the housing, one or more friction elements may be arranged on angular portions that do not have the first and second protrusions. The device may have a plurality of angular portions that do not have the first and second protrusions, particularly two angular portions that do not have opposing first and second protrusions, and at least one, preferably two, and more preferably three friction elements are arranged in each angular portion of the device that does not have the first and second protrusions.

[0067] The inner surface of the housing (particularly the inner surface of the connecting portion) and / or the outer surface of the widened retaining portion of the refiller may have a height measured along the longitudinal axis that is greater than the height of one or more friction elements. When the refiller is in the housing, the device (particularly the housing, and particularly the connecting portion) may have: • A first axial portion, which does not have a friction element and has one or more second protrusions and at least a portion of one or more first protrusions and concaves, and • The second axial portion has at least a portion of one or more friction elements.

[0068] The second axial portion may have one or more second protrusions and a portion of one or more first protrusions and concaves.

[0069] When the friction element is carried by the housing, particularly by the connecting portion of the housing, the second portion preferably extends between the first portion and the refiller reservoir. When the friction element is carried by the refiller, particularly by the widened retaining portion, the first portion preferably extends between the second portion and the refiller reservoir. Therefore, during the assembly of the refiller and housing, the user will first seek to align the longitudinal axes of the refiller and housing, and then, secondly, align the first and second protrusions by rotating the refiller relative to the housing about the longitudinal axis. Then, thirdly, the first and second protrusions are engaged with each other via translational movement along the longitudinal axis through the first portion, so that the friction element of the second portion is finally engaged against the facing surfaces. This makes assembly easier by limiting friction during the step of angular displacement of the first and second protrusions relative to each other. Furthermore, this makes it possible to reduce wear on the friction element by generating frictional contact only after angular displacement of the refiller and housing has been performed and the relative rotation of these elements has been prevented by the first and second protrusions.

[0070] Preferably, the total number of friction elements is even. In this case, the friction elements can be arranged in pairs opposite to each other about the longitudinal axis of the device.

[0071] Each angular portion lacking the first and second protrusions may have at least one, preferably at least two, and more preferably at least three friction elements. The friction elements may be regularly distributed in each angular portion lacking the first and second protrusions. The friction elements are evenly distributed relative to each other around the longitudinal axis. This allows for better retention of the refiller within the housing through the distribution of frictional forces.

[0072] Each friction element can have a maximum thickness between 0.45 mm and 1.2 mm, for example, 0.7 mm.

[0073] Each friction element can extend over an angular range between 10° and 40°, better yet, between 15° and 30° (e.g., 22°).

[0074] Friction elements can be essentially the same. In variations, they differ, particularly in their angular range, shape, and / or size.

[0075] The friction element may have at least one elastically deformable flexible portion that can bend during insertion of the refiller and bulge during removal of the refiller. Therefore, the friction element can provide flexibility to the device during insertion or removal of the refiller, making it easier to use.

[0076] Friction elements can be integral with their extending surfaces, particularly with the connecting portions of the housing or the widened retaining portions of the refiller. This makes it particularly possible to limit the amount of material required for manufacturing, and thus simplifies manufacturing.

[0077] Seals The device may also have a seal or sealing portion that extends between the refiller and the housing when the refiller is in the housing, particularly between the connection portion of the housing and the widened retaining portion of the refiller.

[0078] The seal may be a protruding protrusion extending from one of the inner surface of the housing (particularly from the connecting portion of the housing) and the outer surface of the refiller body (particularly at the widened retaining portion). The seal may extend circumferentially over the entire circumference of either the inner surface of the housing (particularly at the connecting portion) or the outer surface of the refiller body (particularly at the widened retaining portion), and is configured to contact the other of the inner surface of the housing and the outer surface of the refiller body. Such a seal makes it possible to ensure better contact between the refiller and the housing, and therefore better retention.

[0079] In the variant, the seal extends only beyond the first and second recesses, particularly at the first axial portion.

[0080] The seal may be a single piece with one of the inner surface of the housing and the outer surface of the body. The seal may be a circumferential rib that extends from one of the inner surface of the housing and the outer surface of the body over at least a portion of its circumference.

[0081] The seal can extend on the inner surface of the housing at the upper edge of the second protrusion.

[0082] When the refiller is in the housing, the device (particularly the first surface) can have a snap-fit ​​protrusion, particularly a circular groove, facing the seal or sealing portion. This makes it particularly easier to snap the refiller into the housing.

[0083] Buckle fastening The device may also have one or more snap-fit ​​protrusions / recesses on the housing and one or more complementary snap-fit ​​protrusions / recesses on the refiller. One or more snap-fit ​​protrusions / recesses may be disposed on one or more second protrusions / recesses, and one or more complementary snap-fit ​​protrusions / recesses may be disposed on one or more first protrusions / recesses. One or more first protrusions / recesses and / or one or more second protrusions / recesses may have a notch extending over a portion of their height and defining a resilient portion therebetween, with the one or more snap-fit ​​protrusions / recesses and / or one or more complementary snap-fit ​​protrusions / recesses preferentially extending over the resilient portion. This can improve the retention of the refiller in the housing and provide a specific noise or feel upon snap-fit, and it can make it easier for the user to confirm that the refiller is properly secured in the housing.

[0084] One or more first protrusions and / or one or more second protrusions may have friction thickenings. This can improve the retention of the refiller.

[0085] The present invention also addresses this need by means of a refiller belonging to the apparatus described above, the refiller having a refiller body and a cap having elements immersed in the refiller body, the refiller body having a widened portion for holding onto a housing, the widened holding portion having a first protrusion-recession configured to cooperate with a second protrusion-recession of the housing to prevent the refiller from rotating within the housing. The characteristics of the refiller described above in the context of the apparatus can be applied to the refiller independently of the apparatus. Attached Figure Description

[0097] exist Figures 1 to 4 The figure shows a packaging device 1 according to the present invention. The device has a cosmetic refiller 2 having a longitudinal axis X and containing cosmetic products, and a housing 3 having a longitudinal axis Y, the housing 3 having a shell 31 for receiving the refiller 2. When the device 1 is assembled, the longitudinal axes X and Y coincide.

[0098] like Figure 2 As illustrated, the cosmetic refiller 2 has a refiller body 4 containing cosmetic products and a cap 6 for closing the refiller body 4. The refiller body may have a dispensing portion 41 and a reservoir 44 configured to extend into the housing 3, on which the cap 6 is mounted. The reservoir may be substantially cylindrical about a longitudinal axis X.

[0099] The dipping element 7 is secured to the cap 6 of the refiller. In the illustrated embodiment, the dipping element is a pipette 7 secured to the cap 6 and associated with a suction and discharge device arranged in the cap in a manner known per se, allowing the pipette to be loaded with product and allowing the loaded product to be discharged from the pipette for application to the body surface. However, the invention is not limited to dipping elements in the form of pipettes; the dipping element can be any other element configured to collect cosmetic products in a reservoir (particularly in the bottom of the reservoir), particularly an applicator component mounted on a pole, especially a mascara brush or lip or eyeliner applicator. The cosmetic product can be an eyeliner, liquid lipstick, lip gloss, care product, or mascara.

[0100] The cap 6 can be mounted on the refiller body 4 by screwing it onto the dispensing portion 41, particularly on the dispensing portion 41, and especially on the opening of the neck 49 of the dispensing portion 41. The cap 6 may have internal threads on its inner surface, the shape and pitch of which are complementary to the threads 48 present on the neck 49 of the dispensing portion 41 of the refiller body 4.

[0101] As shown in the figure, the refiller body can be elongated along the longitudinal axis X.

[0102] The refiller body 4 may have a widened retaining portion 42 between the dispensing portion 41 and the reservoir 44, and a base 43 connecting the dispensing portion 41 and the retaining portion 42 of the refiller body 4. The base 43 may be connected to the widened retaining portion 42 via a shoulder 47. The widened retaining portion 42 may have a maximum width. p In particular, the diameter is greater than the maximum width of the allocated portion. d And the maximum width r of the storage, such as Figure 8 This is visible in the image. This makes it easier to introduce the refiller into the housing and properly hold the refiller to the housing.

[0103] Preferably, the refiller body 4 is a single piece. It can be made of recyclable and / or recycled materials, particularly polyethylene terephthalate (PET), polypropylene (PP), glass, or cellulose materials, which may be virgin or recycled.

[0104] Furthermore, the refiller 2 may have a funnel-shaped wiping element 9, which is inserted into and secured inside the refiller body 2 at the neck 49 of the dispensing portion 41 of the refiller body 4. The wiping element 9 is of a known type, as is its securing to the neck 49.

[0105] The housing 3 may have a housing body 4 arranged to receive the refiller reservoir 21 via an opening 33 when the refiller 2 is inserted into the housing 3. The housing 3 may have a connecting portion 5, which may be in the form of an attachment ring. The attachment ring 5 can be fastened to the housing body 35 by a snap-fit ​​mechanism. In a variation, the ring may be adhesively attached to the housing. According to another embodiment, the connecting portion 5 may be integral with the housing and may be a single piece with the housing. The housing body may be made of glass.

[0106] like Figure 3 and Figure 4 As illustrated, the reservoir 44 of the refiller body 4 can have a shape that is essentially a rotating cylinder with a rounded bottom 40. The refiller body 4 is arranged to insert into the housing 3 such that the reservoir 44 extends into the housing, and the widened retaining portion 42 cooperates with the ring 5 of the housing at least via a flat portion 10, which cooperates with a second protrusion 53 extending on the ring. The bottom of the refiller body 40 may not contact the bottom 32 of the housing 3, thereby leaving a gap to allow the refiller to have a variable distance from the bottom or a variable height depending on manufacturing tolerances. Furthermore, the outer surface of the refiller body 4 preferably does not contact the inner surface of the housing body, thereby leaving a gap between the two elements of the device. This arrangement makes it possible to protect the refiller, especially in the event of an accidental drop of the device when the refiller is inserted into the housing.

[0107] like Figures 5 to 7 As illustrated, ring 5 may have a connector 51 configured to contact the widened retaining portion 42 of the refiller and a cap 52 fastened to the connector 51. The connector 51 is inserted into the cap 52 of ring 5, and the ring itself is fastened, for example, by snap-fitting to or adhesively bonded to housing 3. The connector and cap may be made of the same plastic material, which may be particularly recyclable and / or reusable. In a variant, the connector is made of a first material, such as a plastic material, like an elastomer or preferably a plastic material having a controlled coefficient of friction that is advantageous in conjunction with the constituent materials of the refiller body, such as polypropylene (PP), polyethylene terephthalate (PET), or polybutylene terephthalate (PBT), and the cap is made of a second material, particularly a plastic having a surface finish, such as a metallized finish, or made of a metallic material such as aluminum.

[0108] The ring 5 may have a housing between the connector 51 and the cover 52 for receiving the body of the housing, and the cover 52 may have one or more protrusions and recesses for snapping fastened to the neck of the body of the housing.

[0109] The widened retaining portion 42 of the refiller body 4 may have at least one first protrusion, in this case having two first protrusions in the form of a flat portion 10, wherein only one is in Figure 2 As can be seen in the illustration. In the example shown, the first protrusion is in the form of a flat portion 10, but this is not always the case. Any protrusion that allows the refiller to be prevented from rotating by the housing through cooperation with the housing is possible. In this case, the two flat portions 10 are symmetrically distributed on the widened retaining portion 42 on either side of the longitudinal axis X.

[0110] At the flat portion 10, a portion of the base 43 may be trimmed across its width to form a chamfer 101. The flat portion 10 is a plane inclined at an angle α relative to the longitudinal axis X, the angle α being, for example, between 3° and 10°, and particularly substantially equal to 3.5°. In a variation, the flat portion 10 may be parallel to the longitudinal axis X. The flat portions 10 have a substantially trapezoidal profile, but they may have different shapes.

[0111] The flat portion may also have a chamfer 102 at its bottom insert edge to facilitate the insertion of the retaining portion 42 of the refiller into the connecting portion.

[0112] The connecting portion 51 has a second protrusion 53 configured to cooperate with the first protrusion 10, particularly the flat portion 10, of the retaining portion 42 of the refiller. The second protrusion 53 may have a flat surface that contacts the flat portion 10, which, when the refiller 2 is inserted into the housing 3, preferably has an angle range θ substantially greater than the angle range β of the flat surface. Therefore, the flat surfaces of the flat portion 10 and the second protrusion 53 form a stop that resists rotation of the refiller 2 relative to the housing 3 about the longitudinal axis X.

[0113] The second protrusion 53 can be laterally defined by a fillet 105, which makes the engagement between the second protrusion 53 and the first protrusion 10 easier without damaging them. Figures 2 to 4 In the embodiment illustrated, there are two flat portions and two concave-convex portions, but this is not mandatory.

[0114] The second protrusion 53 may have a chamfer 104 forming an insertion edge in its upper part, so as to make it easier to insert the retaining part 42 of the refiller into the connecting part.

[0115] Each flat section 10 extends over an angular range θ (e.g., essentially equal to 55°) between 10° and 70°.

[0116] Each second protrusion 53 extends over an angle range β (approximately 50° in this case) that is substantially smaller than the angle range of the flat portion 10.

[0117] The flat portion 10 may have a height of approximately 11 mm measured along the longitudinal axis, and the second uneven portion 53 may have a height H that is slightly smaller than the height of the flat portion 10 (approximately 9 mm) measured along the longitudinal axis. Figure 7 (See diagram in the middle).

[0118] The flat portion 10 can be formed by a flat cut in the outer surface of the retaining portion 42.

[0119] As shown in the diagram, flat surfaces can be vertical. In variations, they can form a non-zero angle α with the vertical direction.

[0120] Therefore, in the illustrated example, when the refiller is inserted into the outer shell of the housing, the flat portion 10 forms a non-zero angle α with the flat surface.

[0121] like Figures 5 to 7 As can be seen, the connector 51 may have a friction element 12 on its inner surface configured to contact the widened retaining portion of the refiller. The friction element 12 may have a height f that is less than the height H of the second protrusion 53.

[0122] according to Figures 5 to 7 In the embodiment illustrated, the connector 51 may have a first axial portion 51a and a second axial portion 51b. A second protrusion 53 for preventing rotation extends on the first axial portion 51a, and the first axial portion 51a does not have a friction element. The second protrusion 53 extends continuously on the second axial portion 51b, and the friction element 12 extends on the second axial portion 51b. The fact that the first axial portion does not have a friction element 12 makes it possible to protect them and limit their wear during insertion, and especially during angular displacement in the housing about the longitudinal axis of the refiller, so that the flat portion 10 and the flat surface 53 coincide, and thus extend their effectiveness over time. Preferably, the second axial portion 51b extends between the first portion 51a and the reservoir 44 of the refiller. The two axial portions 51a and 51b may have heights measured along the longitudinal axis X, and these heights may or may not be substantially the same.

[0123] The friction element 12 can be a protruding protrusion configured to abut against the widened retaining portion and hold the widened retaining portion in the neck of the housing by friction. To remove the refiller from the housing, a force greater than the frictional force generated by the friction element 12 needs to be applied. Preferably, this frictional force is greater than the weight of the filled refiller to prevent the refiller from detaching from the housing under its own weight when the device is manipulated, particularly when inverted. The connector 51 can have an even number of identical friction elements 12, symmetrically arranged on the circumferential portions of the connector 51 outside the flat portions 10. They can be regularly distributed on each circumferential portion outside the flat portions 10.

[0124] like Figure 10 As illustrated, each friction element 12 extends over an angular range λ between 10° and 30° (approximately 22° in this case) on the second axial portion 51b. Each friction element may protrude a thickness e of approximately 0.7 mm. Each friction element 12 may have a fillet 103 on its upper edge surface, which facilitates engagement of the refill holder with these friction elements during insertion of the refiller into the housing.

[0125] Preferably, the friction elements 12 extend between the second protrusions and recesses 53 without being stacked at an angle on the second protrusions and recesses 53. In the illustrated example, the ring 5 has six identical friction elements 12 that extend between the two second protrusions and recesses 53 in two angular portions without the second protrusions and recesses 53, and are distributed at an angle to the second protrusions and recesses 53 about the longitudinal axis.

[0126] Therefore, during the assembly of the refiller 2 and the housing 3, the user will first seek to make the longitudinal axes X and Y of the refiller and the housing coincide, and then, by rotating the refiller relative to the housing about the longitudinal axis to make the first and second concave and convex parts coincide, the refiller is translated downward at the axial portion 51a, and then continues to translate downward into the axial portion 51b so as to place the friction element 12 in friction.

[0127] according to Figure 2 In the embodiment illustrated, the device may have an additional seal. The seal 11 is a protruding protrusion extending between the connecting portion 5 of the housing 3 and the widened retaining portion 42 of the refiller body 4. The seal 11 extends circumferentially over the entire circumference of the inner surface of the connecting portion 5 and is configured to contact the refiller body 4 at the outer surface of the widened retaining portion 42 of the refiller body 4, at the shoulder 47 between the widened retaining portion 42 and the dispensing portion 41, and particularly at the portion adjacent to the flat portion 10 that is not finished by the chamfer 101.

[0128] Such a seal makes it possible to ensure better contact between the widened retaining portion 42 of the refiller body and the connecting portion 5 of the housing, and thus ensure better overall retention between the refiller 2 and the housing 3.

[0129] According to the illustrated embodiment, the friction element 12 is carried by the housing 3, particularly by the connecting portion 5 of the housing. However, in a variation, the friction element may be carried by a refiller, particularly by a widened retaining portion that preferably extends between the second portion and the refiller's reservoir 44. In this case, the first axial portion 51a preferably extends between the second portion 51b and the refiller's reservoir 44.

[0130] according to Figures 10 to 12 In the variant embodiment illustrated, the device may not have a seal. According to... Figures 10 to 12 As illustrated in the figure, the device may have a snap-fitting protrusion 60 on each of the second protrusions 53. According to this embodiment, the second protrusion 53 may have two notches 62 extending over a portion of the height H of the second protrusion 53, defining a snap-fitting portion of the second protrusion between them. The snap-fitting protrusion 60 may extend on the snap-fitting portion of the second protrusion. The presence of the notches 62 makes it possible to provide a certain degree of elasticity to the snap-fitting portion of the second protrusion, which facilitates snap-fitting. The snap-fitting protrusion 60 may be formed by a protruding protrusion extending between the two notches 62.

[0131] like Figure 11 As illustrated, each flat portion 10 of the refiller may have complementary protruding snap-fit ​​protrusions 64, which in particular have a generally elliptical shape. The snap-fit ​​protrusions 60 can be arranged to snap fasten with the corresponding snap-fit ​​protrusions 64 during insertion of the refiller into the housing. This cooperation makes it possible to ensure proper axial retention of the refiller 2 within the housing 3, complementing the friction element 12 to limit the risk of refiller removal. The elasticity of the snap-fit ​​portion provided by the notch 62 facilitates snap-fitting.

[0132] Furthermore, this makes it possible to provide the user with tactile and / or auditory sensations during the snap-fit ​​process, so that he or she can be assured that the refiller 2 is properly secured in the housing 3.

[0133] The notch 62 may be defined on the side opposite to the snap-fit ​​portion of the second protrusion by a thickened portion 63 of the second protrusion. Such a thickened portion may act as a complementary friction element to facilitate the retention of the refiller in the housing and / or at least partially form a flat surface of each second protrusion 53 adapted to cooperate with the corresponding flat portion 10 of the refiller body 4.

[0134] During the insertion of the refiller 2 into the housing 3, the thickened portion 63 of each second protrusion 53 contacts each flat portion 10 of the refiller body 42 to ensure angular rotation of the refiller 2 in the housing 3 and also to help retain the refiller by friction.

[0135] Clearly, the elements just described apply in reverse to the first protrusion and recess. A snap-fit ​​portion with a snap-fit ​​protrusion and recess can be arranged on the first protrusion and recess, and the second protrusion and recess can have complementary snap-fit ​​protrusions and recesses.

[0136] In the absence of a friction element 12 that is different from the second protrusion 53, in addition to preventing the refiller from rotating in the housing by cooperating with the first protrusion 10, the second protrusion 53 can also ensure that the refiller is held in the housing along the longitudinal axis X by friction by providing close contact between the first and second protrusions when the refiller 4 is in place inside the housing 3.

[0137] Many modifications can be made to the apparatus that has just been described without departing from the scope of the invention.

[0138] Therefore, in variations not shown, the number of the first and / or second protrusions and the number and / or properties of the friction elements may be modified without departing from the scope of the invention.

[0139] The position of the seal may be modified without departing from the scope of the invention.
