Description

Title of the invention: Device for conditioning and applying a product. Technical field

[0001] The present invention relates to the closure devices for cosmetic product containers, in particular perfume, makeup product or skincare product.

[0002] More generally, a cosmetic product is a product as defined in Regulation (EC) No 1223 / 2009 of the European Parliament and of the Council of 30 November 2009 on cosmetic products. Previous technique

[0003] Numerous fastening devices exist. For example, a snap-on cover is known, which can be used to cover a cover belonging to a product applicator or a pump mounting flange by incorporating additional snap-on ridges, as illustrated in Figures 1a and 1b of the prior art. As can be seen in Figures 1a and 1b, an insert belonging to the cover incorporates snap-on ridges in its lower part, carried by flexible tabs in the radial direction, and adapted to snap into the rear of a front edge of an applicator cover to secure the cover to the applicator cover.

[0004] It is also known to produce a closure cap comprising an insert in a hood, the insert having flexible tabs at two different heights, more precisely two higher tabs and two lower tabs. This ensures that two tabs, the lower ones, are fully inserted under the screwed part, by ensuring in particular that the snap-on projections they carry are inserted under the front edge of the applicator hood or the pump mounting flange screwed onto the neck of the container, as well as two tabs, the higher ones, which limit any axial movement, either by limiting play or by remaining under constraints in the radial direction after the snap-on projections they carry have passed behind the front edge of the applicator hood or the pump mounting flange, depending on the manufacturing tolerances.

[0005] Cosmetic bottle closure systems comprising one or more magnets to ensure contact between the closure member and the container by a phenomenon of magnetic attraction are also known, for example by utility models CN 217791865 U, CN 207979222 U, and applications JP 2020-89680 and FR 3 056 386.

[0006] Magnetic closure systems are particularly appreciated by consumers, especially for their ease of use and the sensations they provide.

[0007] However, such systems require the use of permanent magnets, which represent a high cost, penalize the recycling of the product at the end of its life and constitute a scarce resource.

[0008] The proposal of eco-responsible, environmentally friendly solutions, whose design and development take into account environmental issues, is becoming a major concern in order to contribute to meeting planetary challenges.

[0009] It is therefore essential to design products that reduce the amount of materials used and / or replace them with more environmentally friendly materials and / or use recyclable materials in order to reduce the carbon footprint of the product.

[0010] There is therefore a need to further improve container closure mechanisms in order in particular to reproduce the behavior of a magnetic closure system, while being inexpensive, reliable and eco-friendly. Summary of the invention

[0011] The invention aims to meet all or part of this need and relates to a device for conditioning and applying a product P, in particular a perfume, makeup product or skincare product, comprising: - a container for holding product P, the container having one or more protruding features, and - a container closure device comprising flexible elastic tabs, each flexible elastic tab having a protruding tab relief,

[0012] the protruding reliefs of the elastic flexible legs cooperating with the protruding relief(s) of the container to allow the closure of the device, the protruding relief(s) of the container and / or the protruding relief(s) of the elastic flexible legs having in longitudinal section a triangular shape, forming inlet and outlet slopes, the inlet and outlet slopes being of different inclinations with respect to a longitudinal axis of the device.

[0013] The term “longitudinal section” means a section containing a longitudinal axis of the device.

[0014] The product may be, but is not limited to, a cosmetic product, such as a perfume, a makeup product or a skincare product.

[0015] The container may have a single protruding relief. The relief may be in relief.

[0016] The projecting relief(s) of the container may take the form of a ridge, in particular a simple ridge, especially one with a semi-circular cross-section, formed on the container. It could be a circular rib, for example, extending around the entire circumference of the container or part of the circumference of the container.

[0017] In one embodiment, the protruding relief(s) of the container may have a triangular shape in longitudinal section, forming inlet and outlet slopes, the inlet and outlet slopes being of different inclinations with respect to a longitudinal axis of the device.

[0018] Alternatively or additionally, the protruding reliefs of the flexible elastic legs may have a triangular shape in longitudinal section, forming entry and exit slopes, the entry and exit slopes being of different inclinations with respect to a longitudinal axis of the device.

[0019] Alternatively, the protruding reliefs of the flexible elastic legs can take the form of a ridge, in particular a ridge with a semi-circular cross-section, formed on the flexible elastic legs.

[0020] In one embodiment, the protruding relief(s) of the container as well as the protruding reliefs of the flexible elastic legs all have a triangular shape in longitudinal section, forming inlet and outlet slopes, the inlet and outlet slopes being of different inclinations with respect to a longitudinal axis of the device.

[0021] The flexible elastic tabs provide elastic flexibility in the radial direction. They can have a spring effect on the closing mechanism, in particular to hold it on the container in the closed position.

[0022] The cooperation of the flexible elastic legs and the protruding relief(s) makes it possible to produce a hard point when opening, then to give the feeling that the opening is easy once the hard point has been passed.

[0023] Upon closing, this cooperation allows for a resistance effort, followed by a sensation that the closing mechanism self-engages on the container, with a release effect once the initial resistance point is overcome. Such a result can be achieved thanks to the shape of the protruding ridge(s).

[0024] The invention allows the user to experience the sensations obtained when opening and / or closing a container where the closing mechanism and / or the container contains one or more permanent magnets. The invention mechanically imitates a magnetic closure of a container, without using a permanent magnet.

[0025] The closing mechanism according to the invention may be without a permanent magnet. The container may be without a permanent magnet. The device may be without a permanent magnet. Description of the invention

[0026] During the closing of the device, over a first portion of the closing element's travel relative to the container, there is a resisting force El, due to the passage of the inlet slope through a protruding feature. Then, after passing a hard point, or high point, which corresponds to the radial apex of the protruding feature, there is a second portion of the closing element's travel relative to the container during which the elastic relaxation of the flexible elastic tabs causes the protruding feature to slide down the outlet slope, without the need to apply an axial force. This provides an initial acceleration that mechanically mimics the entry of a closing element into the magnetic field of a container containing a magnet, and the phenomenon of magnetic attraction mentioned above. Thus, the invention makes it possible to imitate a device comprising one or more magnets.In the first part of the stroke, there is initially a resisting axial force El, linked to the passage of the inlet slope over a protruding feature and corresponding to the radial tension applied to the flexible elastic tabs. In the second part of the stroke, an attraction is simulated by a zero resisting force; the elastic relaxation of the flexible elastic tabs automatically causes the protruding feature to slide down the outlet slope, without the need to apply an axial force. The user does not need to push the closing mechanism; it will be able to position itself on the container.

[0027] During the opening of the device, on a first portion of the stroke, there is a resisting force E2 < El, linked to the passage of the exit slope by a protruding relief and corresponding to the tensioning in the radial direction of the elastic flexible tabs, then, after the passage of a hard point corresponding to the radial top of the protruding relief, there is a second portion of the stroke of the closing member relative to the container on which the elastic relaxation of the flexible tabs automatically causes the sliding of said protruding relief on the entry slope, with a second acceleration greater than the first acceleration, to mechanically mimic the exit of a closing member outside the magnetic field of a container containing a magnet and the sudden absence of magnetic attraction beyond a certain axial stroke of relative separation of these elements.The sliding of the protruding relief on the entry slope in this second part of the opening stroke and the second acceleration generated also allows the closing member to be mechanically given a behavior similar to that of a closing member provided with a series of magnets of alternating polarities cooperating with a series of magnets of alternating polarities carried by the container, with the magnets of the closing member placed opposite the magnets of the same polarity of the container, for example by relative rotation of the closing member and the container from a closing position in which the magnets carried by the closing member are opposite magnets of opposite polarity carried by the container, this placing opposite magnets of the same. The polarity causes the magnetic repulsion of the closing mechanism away from the container. In the initial part of the opening stroke, if the user does not pull the closing mechanism past the resistance point or high point, it will automatically return to its position on the container, thus mechanically mimicking the behavior of a closing mechanism located in the magnetic field of a container containing a magnet. Once the resistance point is passed, no further effort is required; the sensation is imitated as the magnetic field lines emerge and magnets of the same polarity align on two objects, tending to repel each other.

[0028] The resisting force is lower at the opening because the inlet slope may be greater than the outlet slope for one or all of the protruding reliefs. Protruding relief of the container

[0029] The protruding relief(s) of the container may have a triangular shape in longitudinal section, forming inlet and outlet slopes, the inlet and outlet slopes being of different inclinations with respect to a longitudinal axis of the device.

[0030] The entry slope (angle |3) may be greater than the exit slope (angle a). Since the entry slope is more inclined with respect to the longitudinal axis of the device than the exit slope, a sensation of acceleration is obtained during closing, once the elastic flexible tabs have passed the high point in the radial direction of the protruding relief, as well as a sensation of acceleration during opening, once the elastic flexible tabs have passed the high point in the radial direction of the protruding relief, the acceleration during closing being in particular less than the acceleration during opening.

[0031] Since the inlet slope is greater than the outlet slope, when the container is closed by the closing member, the closing stroke is shorter before the high point on its first portion of the stroke, and the closing stroke is longer after the high point on its second portion of the stroke.

[0032] Furthermore, since the inlet slope is greater than the outlet slope, when the container is opened by the closing device, the opening stroke is longer before the high point on its first part of the stroke, and the opening stroke is shorter after the high point on its second part of the stroke.

[0033] In addition, such a configuration makes it possible to reduce the axial bulk.

[0034] The inlet slope and the outlet slope may form an angle with each other which may to be between 60 and 160°, or even between 90 and 150°, better between 110 and 140°, being for example 130°.

[0035] The angle [3 of the inlet slope with respect to the longitudinal axis of the device can be between 10 and 89°, or even between 15 and 60°, better between 20 and 40°, being for example 30°.

[0036] The angle a of the outlet slope with respect to the longitudinal axis of the device can be between 5 and 80°, or even between 7 and 50°, better between 10 and 30°, being for example 20°.

[0037] In one embodiment, we have [3 - a > 10°.

[0038] A height r of the protruding relief, measured in the radial direction, perpendicular to the longitudinal axis of the device, can be between 0.5 and 5 mm, or even between 0.8 and 3 mm, better between 1 and 2 mm, being for example 1.3 mm.

[0039] A ratio of the height r of the protruding relief to a diameter d of a neck of the container bearing the protruding relief, measured perpendicular to the longitudinal axis of the device, can be between 0.02 and 0.25, or even between 0.04 and 0.14, better between 0.05 and 0.09, being for example 0.06.

[0040] A length 1 of the protruding relief, measured parallel to the longitudinal axis of the device, can be between 4 and 15 mm, or even between 5 and 10 mm, better between 6 and 8 mm, being for example 6.3 mm.

[0041] A ratio r / 1 of the height r of the protruding relief to the length 1 of the protruding relief can be between 0.1 and 1, or even between 0.15 and 0.5, better between 0.18 and 0.3, being for example 0.2.

[0042] A length x of the outlet slope, measured parallel to the longitudinal axis of the device, can be between 2 and 10 mm, or even between 2.5 and 8 mm, better between 3 and 5 mm, being for example 3.75 mm.

[0043] The length x of the exit slope can correspond to a return effect allowing the user to imitate the sensations obtained when opening and / or closing the container when the closing mechanism contains one or more permanent magnets providing a return effect.

[0044] A length y of the inlet slope, measured parallel to the longitudinal axis of the device, can be between 1 and 10 mm, or even between 1.5 and 8 mm, better between 2 and 5 mm, being for example 2.55 mm.

[0045] The flexible elastic leg(s) can deform over a stroke of the closing member by at least the length x of the exit slope, measured parallel to the longitudinal axis of the device, before crossing the high point of the protruding relief or before returning to its or their original position.

[0046] Thus, the choice of the different measurements listed above of the protruding relief makes it possible to give the desired automatic closing effect in the invention.

[0047] Furthermore, the protruding relief(s) of the container are configured so as to allow the flexible elastic tab(s) to remain without elastic stress in the closed position of the closing element on the container, in particular thanks to the choice of these different measures.

[0048] Alternatively, the flexible elastic tab(s) remain slightly elastically deformed in the radial direction when the closing mechanism is closed on the container. This results in tension on the flexible elastic tabs in the closed position, with the closed position and axial stop being reached before the end of the elastic return stroke of the flexible elastic tabs. This allows for maintaining slight tension to avoid any play due to manufacturing tolerances and provides the desired automatic closing effect, which extends to the point of contact between the closing mechanism and the container. This alternative is preferred.

[0049] The device can be configured to be sealed in the closed position of the organ The closure mechanism on the container can be configured to prevent movement of the closure element when closed, particularly during transport. The various measures can be selected accordingly. An axial force component can be maintained by the closure element on the container when closed.

[0050] According to the invention, at the end of the closing mechanism's travel, there is contact between the closing mechanism and the container, in particular a shoulder on the container extending perpendicularly to the longitudinal axis of the device. This provides a true, firm stop. To this end, the container may comprise a bottle and a neck to receive the closing mechanism, the neck forming a shoulder with the bottle, against which the closing mechanism abuts when closed on the container. The shoulder may extend perpendicularly to a longitudinal axis of the device.

[0051] Alternatively, the closing member may not abut against the shoulder, particularly in the closed position on the container.

[0052] In one embodiment, the container may include a plate covering the shoulder. The plate may be made of a material less hard than the material of the container, in particular the bottle and / or the neck, and thus facilitate the stopper mechanism's engagement.

[0053] Alternatively, the plate can be made of a harder material than the container material, in particular the bottle and / or the neck, thereby strengthening the contact of the closure element, especially when the container material, in particular the bottle and / or the neck, is a soft material. This can also advantageously produce a different sound during use.

[0054] The container may include a neck for receiving the closure element and a flange inserted onto the neck, the protruding feature(s) being formed on the neck or on the flange. In one embodiment, the neck includes the protruding feature(s). Alternatively, the flange inserted onto the neck includes the protruding feature(s). The flange may be used for attaching a pump, as described below. Closing mechanism

[0055] The closing mechanism may comprise a cover and an insert inserted into the cover, the flexible elastic tabs being carried by the cover or by the insert. In one embodiment, the cover carries the flexible elastic tabs. Alternatively, the insert inserted into the cover carries the flexible elastic tabs.

[0056] The presence of two parts for the closing mechanism allows for more travel for the deformation of the flexible elastic tabs, particularly radially between the cover and the insert.

[0057] Furthermore, the closing mechanism may include a spring-loaded part with flexible elastic tabs, which is attached to the cover or insert. In one embodiment, the cover carries the spring-loaded part with the flexible elastic tabs. Alternatively, the insert inserted into the cover carries the spring-loaded part with the flexible elastic tabs.

[0058] Making the closing mechanism in several parts, in particular the cover, the insert and / or the spring part, advantageously allows the choice of different materials for each, in particular the cover, the insert and / or the spring part.

[0059] In one embodiment, the spring component may, for example, be made of a material chosen from the following, which is not exhaustive, list: plastic material, PBT, PP, POM, PET, PETG, metallic material, aluminum, steel, stainless steel. The material may have shape memory. It may have good strength. It may be chosen so that the elastic return is maintained.

[0060] In one embodiment, the insert may, for example, be made of a material chosen from the following, which is not exhaustive: PP, PE, PET, PETG. The material may have good resistance, as well as an attractive appearance. Indeed, the insert may be visible to users, and its appearance may be a criterion for choosing the material.

[0061] In one embodiment, the hood may, for example, be made of a material chosen from the following, which is not exhaustive, list: plastic material, PP, PET, PETG, metallic material, aluminum, steel, stainless steel, glass, wood. The material may have good resistance, as well as an attractive appearance.

[0062] In one embodiment, the closing element can be weighted to increase its mass, in particular by receiving ballast to increase its weight, and thus approach the mass of a magnetic closing element and even more closely imitate its behavior. Indeed, the mass of the closing element determines its inertia and the sliding, particularly on the entrance slope, of the protruding surface. Flexible, elastic legs

[0063] The device, in particular the spring piece, may include a plurality of elastic flexible legs, in particular between 1 and 8 elastic flexible legs, in particular between 2 and 6 elastic flexible legs, including in particular three or four elastic flexible legs.

[0064] The protruding reliefs of the flexible elastic legs can have a triangular shape in longitudinal section, forming entry and exit slopes, the entry and exit slopes being of different inclinations with respect to a longitudinal axis of the device.

[0065] The entry slope (angle |3') may be greater than the exit slope (angle a'). Since the entry slope is more inclined with respect to the longitudinal axis of the device than the exit slope, a sensation of acceleration is obtained during closing, once the elastic flexible tabs have passed the high point in the radial direction of the protruding relief, as well as a sensation of acceleration during opening, once the elastic flexible tabs have passed the high point in the radial direction of the protruding relief, the acceleration during closing being in particular less than the acceleration during opening.

[0066] Since the inlet slope is greater than the outlet slope, when the container is closed by the closing member, the closing stroke is shorter before the high point on its first portion of the stroke, and the closing stroke is longer after the high point on its second portion of the stroke.

[0067] Furthermore, since the inlet slope is greater than the outlet slope, when the container is opened by the closing device, the opening stroke is longer before the high point on its first part of the stroke, and the opening stroke is shorter after the high point on its second part of the stroke.

[0068] The inlet slope and the outlet slope can form an angle between them which can be between 60 and 160°, or even between 90 and 150°, better between 110 and 140°, being for example 130°.

[0069] The angle [3' of the inlet slope with respect to the longitudinal axis of the device can be between 10 and 89°, or even between 15 and 60°, better between 20 and 40°, being for example 30°.

[0070] The angle a' of the outlet slope with respect to the longitudinal axis of the device can be between 5 and 80°, or even between 7 and 50°, better between 10 and 30°, being for example 20°.

[0071] In one embodiment, we have [3' - a' > 10°.

[0072] A height r' of the projecting relief, measured in the radial direction, perpendicular to the longitudinal axis of the device, can be between 0.5 and 5 mm, or even between 0.8 and 3 mm, better between 1 and 2 mm, being for example 1.3 mm.

[0073] A ratio of the height r' of the protruding relief to a diameter d of a neck of the container, measured perpendicular to the longitudinal axis of the device, can be between 0.02 and 0.25, or even between 0.04 and 0.14, better between 0.05 and 0.09, being for example 0.06.

[0074] A length 1' of the protruding relief, measured parallel to the longitudinal axis of the device, can be between 4 and 15 mm, or even between 5 and 10 mm, better between 6 and 8 mm, being for example 6.3 mm.

[0075] A ratio r' / l' of the height r' of the protruding relief to the length 1' of the protruding relief can be between 0.1 and 1, or even between 0.15 and 0.5, better between 0.18 and 0.3, being for example 0.2.

[0076] A length x' of the exit slope, measured parallel to the longitudinal axis of the device, can be between 2 and 10 mm, or even between 2.5 and 8 mm, better between 3 and 5 mm, being for example 3.75 mm.

[0077] The length x' of the exit slope can correspond to a return effect allowing the user to imitate the sensations obtained when opening and / or closing the container when the closing mechanism contains one or more permanent magnets providing a return effect.

[0078] A length y' of the inlet slope, measured parallel to the longitudinal axis of the device, can be between 1 and 10 mm, or even between 1.5 and 8 mm, better between 2 and 5 mm, being for example 2.55 mm.

[0079] In one embodiment, we can have: a = a' r = r' 1 = 1' x = x' y = y' Thus, in this embodiment, the protruding reliefs of the legs and the protruding relief(s) of the container have an analogous and complementary shape.

[0080] In one embodiment, the spring element may include a Y-shaped branch. This Y-shaped branch provides one or more spring tabs, which can bear against the inside of the cover to impart radial flexibility to the elastic tabs. In this embodiment, the elastic tab can deform within a space provided between the spring element and the cover.

[0081] Alternatively, a flexible elastic leg can be formed by a notch in the spring piece.

[0082] In one embodiment, the flexible elastic tab(s) may have a lower end held in the insert or in the cover. In this embodiment, the lower end of the flexible elastic tab held in the insert or in the cover acts as a spring and hinge, allowing the deformation of a central portion of the flexible elastic tab.

[0083] Alternatively or additionally, the flexible elastic tab(s) may have an upper end held in the insert or in the cover. In this embodiment, the upper end of the flexible elastic tab held in the insert or in the cover acts as a spring and hinge, allowing the deformation of a central portion of the flexible elastic tab.

[0084] The flexible elastic leg(s) can be held in the insert or in the hood at each of their two ends.

[0085] Alternatively, the flexible elastic tab(s) may have a free upper end. According to another embodiment, the flexible tab(s) may have a free lower end. In these embodiments, the upper or lower end of each of the flexible elastic tabs is free, not being retained on the cover or insert. The flexible elastic tab can thus deform more easily.

[0086] The spring part can be made of a more rigid plastic material, for example POM or metal, allowing a good spring effect to be obtained without plastic deformation.

[0087] In one embodiment, the closing element comprises fewer parts, for example a single part or only two parts, made, for example, of a plastic material. Recycling can thus be facilitated.

[0088] The container may include a pump for dispensing product P. In one embodiment, the container may include a bottle and a pump for dispensing product P. Alternatively, it may be without a pump. The invention can be applied to any device comprising a container and a closure element.

[0089] Product P may be a product to be dispensed from the container, in particular by means of an applicator or a pipette. The device may include an applicator, or alternatively, be without one. The invention can thus also be applied to a solid lipstick mechanism, forming the container holding the product in the form of a lipstick stick, and associated with a closing cap.

[0110] Figures 2a to 2d illustrate a device 1 for packaging and applying a product P, such as makeup or skincare, comprising a container 10 for holding the product P, shown in [Fig. 2b], and a closure element 20 for the container 10, shown in [Fig. 2a]. In this example, the container 10 includes a bottle 11 and a pump 12 for dispensing the product P, to be drawn from the container 10.

[0111] The closing member 20 of the container 10 has four flexible elastic tabs 22, visible in figures 2a, 2c and 2d.

[0112] The container 10 has a raised relief 15 that cooperates with the flexible elastic tabs to allow the device to be closed, as illustrated in [Fig. 2d]. In this example, the raised relief 15 is in the form of a simple ridge on the container. Here, it is a circular rib around the entire circumference of the container, as seen in [Fig. 2b].

[0113] The projecting relief 15 of the container 10 has a triangular shape in longitudinal section, forming inlet slopes 16 and outlet slopes 17, the inlet slopes 16 and outlet slopes 17 having different inclinations with respect to a longitudinal axis X of the device. The inlet slope 16, measured by the angle [3, is greater than the outlet slope 17, measured by the angle a.

[0114] The inlet slope 16 and the outlet slope 17 can form an angle with each other which is, for example, approximately 130°. The angle [3] of the inlet slope 16 with respect to the longitudinal axis of the device is, for example, 30°. The angle a of the outlet slope 17 with respect to the longitudinal axis of the device is, for example, 20°.

[0115] A height r of the protruding relief 15, measured in the radial direction, perpendicular to the longitudinal axis X of the device, is for example 1.3 mm. A ratio of the height r of the protruding relief to the diameter d of a neck of the container bearing the protruding relief 15, measured perpendicular to the longitudinal axis X of the device, is for example 0.06.

[0116] A length 1 of the protruding relief 15, measured parallel to the longitudinal axis X of the device, is for example 6.3 mm.

[0117] A ratio r / 1 of the height r of the protruding relief 15 to the length 1 of the protruding relief 15 is for example 0.2.

[0118] A length x of the outlet slope 17, measured parallel to the longitudinal axis X of the device, is for example approximately 3.75 mm.

[0119] A length y of the inlet slope 16, measured parallel to the longitudinal axis of the device, is for example approximately 2.55 mm.

[0120] Furthermore, each flexible elastic leg 22 has a protruding relief 15 cooperating with the protruding relief 15 of the container. This protruding relief 15 of a flexible elastic leg 22 has a triangular shape in longitudinal section, forming inlet slopes 16' and outlet slopes 17', the inlet slopes 16' and outlet slopes 17' having different inclinations with respect to a longitudinal axis X of the device. The inlet slope 16', measured by the angle |3', is greater than the outlet slope 17', measured by the angle a'.

[0121] The inlet slope 16' and the outlet slope 17' form an angle of approximately 130°. The angle 3' of the inlet slope 16' with respect to the longitudinal axis of the device is, for example, 30°. The angle α' of the outlet slope 17' with respect to the longitudinal axis of the device is, for example, 20°.

[0122] A height r' of the protruding relief 15, measured in the radial direction, perpendicular to the longitudinal axis X of the device, is for example 1.3 mm. A ratio of the height r' of the protruding relief to the diameter d of a neck of the container bearing the protruding relief 15, measured perpendicular to the longitudinal axis X of the device, is for example 0.06.

[0123] A length 1' of the protruding relief 15, measured parallel to the longitudinal axis X of the device, is for example 6.3 mm.

[0124] A ratio r' / l' of the height r' of the projecting relief 15 to the length 1' of the projecting relief 15 is for example 0.2.

[0125] A length x' of the outlet slope 17, measured parallel to the longitudinal axis X of the device, is for example approximately 3.75 mm.

[0126] A length y' of the inlet slope 16', measured parallel to the longitudinal axis of the device, is for example approximately 2.55 mm.

[0127] In the example described, we can note that we have: a = a' , [3 = [3' , r = r' , 1 = 1' , x = x' , y = y' . Thus, in this embodiment, the projecting reliefs of the legs and the projecting relief of the container have an analogous and complementary form.

[0128] At the end of the closing mechanism's travel, there is contact between the closing mechanism and the container, specifically with a shoulder of the container extending perpendicularly to the longitudinal axis of the device, as illustrated in [Fig. 2d]. This provides a true, firm stop. To this end, the container has a neck 13 of the bottle 11 to receive the closing mechanism. The neck 13 forms a shoulder 14 with the bottle 11, against which the closing mechanism abuts when closed on the container. Furthermore, in the illustrated example, the container has a plate 18 covering the shoulder 14.

[0129] Furthermore, the container includes a collar 19 inserted on the neck 13 of the container 10, the raised relief 15 being formed on the collar 19. The collar 19 can be used for fixing the pump 12.

[0130] On the other hand, the closing member 20 comprises a cover 23 and an insert 24 inserted into the cover 23, the flexible elastic tabs 22 being carried by the insert 24. The presence of two parts for the closing member allows for more travel for the deformation of the flexible elastic tabs radially between the cover 23 and the insert 24.

[0131] In addition, the closing member 20 includes a spring piece 25 having elastic flexible tabs 22, which is fixed to the insert 24.

[0132] In the embodiment of figures 2a to 2d, a flexible elastic leg 22 is formed by a step in the spring piece.

[0133] In the embodiment shown in Figures 2a to 2d, the flexible elastic tabs 22 have lower ends 22a held in the insert 24 and upper ends 22b held on the insert 24 and, moreover, specifically connected to each other. The lower end 22a and the upper end of each flexible elastic tab 22 held in the insert 24 act as a spring and a hinge, allowing the elastic deformation of a central portion of the flexible elastic tab located between the lower end 22a and the upper end 22b.

[0134] Alternatively, as illustrated in Figures 3a to 3c, the spring part 25 has a Y-shaped branch 27 which provides spring tabs, which can bear against the inside of the hood to provide flexibility in the radial direction to the elastic flexible tabs 22. Thus, the elastic flexible tab 22 can deform in a space provided between the insert 24 and the cover 23.

[0135] In the embodiment shown in Figures 3a to 3c, the upper ends 22b of the flexible elastic tabs 22 are held on the insert 24 and connected to each other, while the lower ends 22a of the flexible elastic tabs 22 are free. In this embodiment, the upper end 22b of the flexible elastic tabs 22 acts as a hinge, and the Y-shaped branch 27 of the flexible elastic tabs 22 acts as a spring, allowing elastic deformation of the flexible elastic tab.

[0136] Alternatively, the lower end of the flexible elastic tabs can be held in the insert 24 by a recess 30 formed in the insert 24, which allows the lower ends 22a to act as hinges, as illustrated in Figures 5a to 5c. In this case, the lower ends 22a of the flexible elastic tabs 22 are not connected to each other.

[0137] Furthermore, in the embodiments just described, the elastic flexible legs 22 have an upper end 22b held in the insert 24. The upper end 22b of the elastic flexible leg 22 held in the insert 24 acts as a spring and hinge, allowing the deformation of a central part of the elastic flexible leg.

[0138] Thus, the flexible elastic tabs can be held in the insert or in the hood at each of their two ends 22a and 22b.

[0139] Alternatively, as illustrated in Figures 4a to 4d, the flexible elastic tabs have a free upper end 22b. In this embodiment, the upper end 22b of each of the flexible elastic tabs 22 is free, not being retained on the cover or the insert. The flexible elastic tab 22 can thus deform more easily. The spring element 25 can in this case be made of a more rigid plastic material, for example POM, PBT, or metal, making it possible to obtain a good spring effect without plastic deformation.

[0140] In one embodiment, the closing member comprises fewer parts, for example, a single part or only two parts, made, for example, of a plastic material. By way of example, Figures 6a to 6c illustrate a two-part embodiment in which the closing member 20 comprises a cover 23 and an insert 24 inserted into the cover, the flexible elastic tabs 22 being carried by the insert 24. It is the insert 24 inserted into the cover that directly carries the flexible elastic tabs 22. The insert 24 and the flexible elastic tabs 22 are a single unit.

[0141] Furthermore, in this embodiment, the raised relief of each flexible leg 22 is formed from its end 22c and only the container has a raised relief having in longitudinal section a triangular shape, forming inlet slopes 16 and outlet slopes 17, the inlet and outlet slopes being of different inclinations with respect to a longitudinal axis X of the device.
