Cosmetic product container with a lid guided by an internal rod

Abstract

The cosmetic product container (1), suitable for portable use, comprises a base (2) housing an insert (3) that defines a compartment for the product, with an opening surrounded by a peripheral rim (32) extending radially from a lateral wall of the insert to a peripheral wall (22) of the base. The container's lid (5) hermetically covers this opening and is held closed when an associated perpendicular rod (61), passing through the rim, is in its maximum insertion position, i.e., proximal to the bottom of the container. Pushing on the outside of the lid overcomes any constraint or locking by moving the lid along an inclined upper surface (S32) of the rim (32), compatible with a rising of the rod that guides the lid's movement, this movement then being generally parallel to the plane of the opening. The container can be part of a cap sealing a larger packaging assembly.Figure from the summary: Figure 1B.

Description

Title of the invention: Container for cosmetic product provided with a cover guided by an internal rod Technical field

[0001] The present disclosure relates to the field of cosmetic product containers. Prior art

[0002] Document US 10398206 discloses a container for cosmetic products and accessories comprising a body intended to receive cosmetic accessories, and a cap comprising several reservoirs intended to receive cosmetic products. The compartments of the cap are connected to each other by means of a rod, itself fixed to a spring imposing a vertical downward movement on it, so as to create a vertical tension between the compartments allowing them to remain in place in the open or closed position. The compartments can pass between the open position and the closed position by rotation around the rod, and the cover opens and closes by means of a hinge.

[0003] One of the disadvantages of the cap of this container is that the size due to the opening / closing system is too large. This limits its interest and, moreover, the cap is not very suitable for nomadic use, for example to be carried in a handbag.

[0004] Another disadvantage is the lack of tightness of the cap.

[0005] There is therefore a need for a waterproof cosmetic product container, allowing good conservation of the cosmetic product, and of minimal bulk. Summary

[0006] In order to improve the situation, a cosmetic product container is proposed comprising: - a base comprising a lower surface and a peripheral wall extending from the lower surface and upwards to delimit an interior volume, - an insert including a space for receiving the cosmetic product and a peripheral edge, the insert mounted in the interior volume being hollow to delimit the receiving space which is accessible through an upper opening surrounded by the peripheral edge, - a cover, movable relative to the base and the insert between a closed position, in which the cover prevents access to the cosmetic product, and an open position, in which the cosmetic product is accessible via the upper opening; - a sealing system preventing the cosmetic product from coming into contact with an external environment when the lid is in the closed position; - an opening / closing system, capable of moving the lid between the open position and the closed position, comprising a rod located at a rear of the lid and housed in a hole in the peripheral edge of the insert, the rod cooperating with the lid and extending from the lid towards the lower surface of the base while being configured to move transversely with respect to the lower surface of the base to pass from one to the other between a position (rod position) proximal to the lower surface and a position (rod position) distal to the lower surface; - a constraint system constraining the lid in the closed position, for example by biasing and / or maintaining (retaining) the rod towards its proximal position, so that the lid cannot move from the closed position to the open position without a force or thrust being exerted on an external part of the lid forming an external surface of the container; and wherein, for said proximal stem position, the cover rests on an upper surface of the peripheral edge of the insert which has an inclination (sloping down towards an edge of the upper opening).

[0007] Typically, the opening / closing system is capable of being actuated by a push of the lid, preferably by a push exerted by a finger on the lid, which may allow opening. A lid actuating portion may be provided in the lid on a front side, opposite the rear region where the rod connects to the lid.

[0008] The cover is for example embedded in the base in the closed position and can follow the inclined upper surface during closing / embedding. The cover is able to slide following the inclination of the upper surface to cause a transverse movement (lowering) of the rod from and / or to its proximal position.

[0009] Where appropriate, the opening / closing system is devoid of a lock, the constraint system including a return member urging the rod towards its proximal position (downwards / towards the bottom of the base) and which is the only member of the container to exert an axial retaining action, parallel to the rod. Alternatively, the opening / closing system may include a locking element with axial retention effect on / against the peripheral edge.

[0010] A locking element as mentioned above may be located, for example, on the front of the lid (opposite the rod-closing portion of the lid junction). Such a locking element may optionally be hidden in the interior volume in the closed position, and is typically operable in response to a push or action exerted on the lid to enable the lid to be locked / unlocked. The locking element may be elastically deformable to engage a gripping edge or rim of the peripheral edge, optionally movable in response to an axial or lateral push on an actuatable portion of the lid. to disengage from the grip edge or ledge.

[0011] The upper surface of the peripheral edge may extend entirely above a plane of the access opening to the compartment / interior space (partitioned or not) where one or more products are housed.

[0012] In the closed position, the rod can be completely hidden, constituting an internal rod. It is then possible to hide the locking mechanism of the closed position, which limits the risk of external damage to this mechanism.

[0013] With this arrangement, it is possible to have an ergonomic cover, providing an annular seal with typically locking of the position of the cover at the level of the rod which is typically hidden, which allows for example to refine the external geometry of the container or at least to have flexibility in the external covering on the periphery of the container.

[0014] In embodiments, in the closed position, an inner surface of a peripheral end of the cover, in the contact portion, rests on an upper surface of the peripheral edge of the insert, knowing that the inner surface of the peripheral end of the cover and the upper surface of the peripheral edge of the insert have an inclination (for example at the same angle relative to a plane of extension of the cover), so that the thrust (on the cover) is capable of causing a translation of the cover induced by a sliding between the respective inclinations of the inner surface of the peripheral end of the cover and of the peripheral edge of the insert, causing the transverse displacement of the rod relative to the lower surface of the base to move the rod from the proximal position to a distal position of the lower surface, and thus causing the cover to move from the closed position to the open position.

[0015] The cover extends perpendicular to the central axis of the side wall of the insert or to the axis of the rod, preferably along a plane, this plane being able to be defined by the external face of the cover.

[0016] An angle of inclination of the peripheral edge is provided which is for example less than or equal to 45 or 60°, relative to a plane of the cover, preferably less than 30 or 40°. This angle of inclination can define a constant slope in the peripheral edge and distributed over 360°. Alternatively, such an angle of inclination corresponds to a maximum of the slope.

[0017] In options, with respect to a plane of the top of the base, corresponding to an opening or upper part through which the insert is mounted in the base, it is formed: - a first angle, by the upper surface of the peripheral edge, this first angle being able to be between 5 and 50°; and - a second angle, by the peripheral end of the cover constituting the contact part with the peripheral edge, this second angle being able to be between 5 and 50°. Optionally, these two angles are substantially complementary. In addition, the extension plane of the cover is typically parallel to the plane of the top of the base which is delimited by the top of the peripheral wall.

[0018] The inclination of the upper surface of the peripheral edge may have a curvature as seen in longitudinal profile, which creates a concave profile on the inner side, delimiting access to the compartment / inner space for the cosmetic product. A similar curvature is for example provided on the inside of the lid, i.e. on the side of the contact part of the lid.

[0019] The insert has an annular side wall which extends around a central axis. Optionally, the lid is carried by a rod defining an axis substantially parallel to the central axis, which is for example an internal rod / not visible (from the outside of the container) in the closed position. The hole, formed in the peripheral edge and crossed by the rod can be: - offset, higher or possibly lower, relative to an annular sealed contact zone (cover - peripheral edge) produced by the sealing system; - and / or interposed, radially, between a first sloping portion, in the upper surface of the peripheral edge, which is adjacent to an internal annular edge delimiting the upper opening, and a second sloping portion, formed in the upper surface of the peripheral edge, extending to an annular end of the upper surface of the peripheral edge which constitutes an outer circumference of the peripheral edge (and typically an outer circumference of the insert).

[0020] According to one feature, the rod is configured to: - pulling (pulling from below) and adjusting in height a sealing part which is part of the cover and which completely covers the upper opening in the closed position, the sealing part fitting into the base while being housed in the interior volume in the proximal position of the stem; and - protrude axially above the peripheral edge in the distal position of the stem, allowing the rear of the cover to be movable above the peripheral wall.

[0021] Typically, the base may be an outer covering shell. In options, only the base and a top portion of the lid are visible (forming the outer covering portion), in the closed position / configuration of the container. The insert may then be entirely hidden.

[0022] In the peripheral edge delimiting the upper opening of the container, the inclination or slope of the upper surface may be provided on either side of a plane of symmetry parallel to the rod and directed from the front to the rear of the lid. A restoring force permitted by the constraint system may be exerted to facilitate the return and / or maintaining it in the closed position. Thus, a user who operates the lid, for example following a rotation, to move the front of the lid to the right or left until reaching or crossing (axially) the top of the peripheral wall of the base by going up the slope of the upper surface, overcomes a force (typically a restoring force) exerted by the constraint system but benefits from a sliding effect, thanks to the inclination. This actuation can also be facilitated by being carried out at the front, therefore at a distance from the axis of the rod which locates the rear of the lid.

[0023] It is understood that the cover which slides to one side (on the left from the front for example) to go up the slope will also be lifted on the rear side (and to the left) due to the guidance by the slope. Typically if a restoring force is exerted at the level of the rod, the restoring effect ceases to be felt / is no longer maintained as soon as the cover has crossed a displacement threshold corresponding to the crossing of a slope: the closing part of the cover in fact abuts axially on the top of the peripheral wall. Conversely, the restoring effect facilitates the positioning (in the manner of a fine adjustment following a first rough angular displacement) of the cover in its final closed position as soon as the cover has approached sufficiently to its final position (combined effects of the recall by the constraint system and the downward slope to slide the cover towards the hermetically closed position).

[0024] In certain options, the return effect is eliminated and a simple locking of the closed position of the cover is provided by an axial retaining effect (peripheral edge - closing part of the cover), for example obtained by an elastically deformable member, which allows easy unlocking by pushing on an accessible part of the cover.

[0025] Optionally, one or more of the following provisions are provided: - in the closed position (with the cover at least partially inserted into the interior volume of the base), an inner surface of a peripheral end of the cover rests on the upper surface of the peripheral edge. - the internal surface of the peripheral end of the cover and the upper surface of the peripheral edge have a substantially identical inclination. - the cover has a closure part configured to move, in response to the thrust exerted on the outer part of the cover in the closed position, following a translation induced by a sliding between said respective inclinations of the inner surface of the peripheral end of the cover and of the upper surface of the peripheral edge, to a raised position causing a movement of the rod to move the rod from the proximal position to the distal position. - the movement of the rod corresponds to a movement parallel to the general direction of insertion or embedding of the cover in the interior volume of the base, and / or to a transverse movement relative to the lower surface of the base, and thus causing the cover to pass between the open position and the closed position. - the insert has a side wall to delimit the reception space (which is only made accessible when the cover leaves its closed position). - the side wall extends annularly around a central axis joining the peripheral edge by an upper axial annular end which is opposite the lower surface. - the upper axial annular end of the side wall (possibly cylindrical wall, optionally annular and continuously rounded / curved), delimits the upper opening. - the upper opening extends entirely into the interior volume. - the peripheral, annular edge may have a generally truncated cone-shaped or partly spherical shape limited by two of its parallels, rising radially outwards from the upper axial annular end, towards the top of the peripheral wall.

[0026] According to a feature, the cover includes the rod which defines an axis of rotation of the cover. To move from the closed position to the open position and vice versa, the closure portion of the cover and the rod (and typically the entire cover) are further capable of being rotated about the axis of rotation of the cover by the thrust, exerted at a front of the cover and in a direction transverse to the axis of rotation and which is perpendicular to a straight line (along the plane of the cover) connecting the rear of the cover to the front of the cover. Such a direction can be described as a generally tangential (non-radial) direction, the front of the cover typically being a point or region diametrically opposite the rod. Thanks to this type of rotational actuation, a rotation is created which induces the sliding of the cover on the upper, inclined surface of the peripheral edge.

[0027] The inclination of the upper surface of the peripheral edge does not block this actuation and rather guides the movement component in the up-down direction, knowing that the lowest position of the cover corresponds to the closed position. The upward sliding on the upper surface can also make it possible to overcome the restoring force which can be exerted on the rod (restoring force for a retaining effect in the closed position), without however exerting an axial traction directly opposite / in the opposite direction to the restoring force.

[0028] According to embodiments, the opening / closing system further comprises a fixed guide zone, formed by a guide (for example included in the insert) to substantially cylindrical structure surrounding the rod, the guide zone cooperating with an anchoring part included in or made integral with the rod. Typically, the anchoring part is provided at a lower end of the rod. Thanks to this coupling / guiding, a controlled axial displacement of the cover is allowed during rotation around the axis of rotation, this axial displacement depending on the displacement of the anchoring part relative to the guide zone, preferably on the displacement of at least one lug (of this anchoring part or of the guide) in a helical rail or groove constituting the complementary part for the guiding effect.

[0029] In a sub-option, helical guidance is permitted by using one or more lugs in an anchoring part, for example made integral with the rod, the helical rail which receives this or these lugs constituting the fixed guide zone in the guide. In another sub-option, it is the rod which has, on its external lateral face, a helical rail, in hollow or in projecting relief, to cooperate with a fixed relief provided in the guide. In the latter case, a lug may be provided, for example located on the fixed guide zone formed by the cylindrical structure (structure which may extend under the peripheral edge and in the interior volume of the base, surrounding the rod).The helical rail is formed along the rod and, here too, the force or thrust on the cover causes the relative movement of the helical rail (of the rod) with respect to the fixed lug, thus causing the said cover to move between the closed position and the open position with a helical guiding effect.

[0030] The opening / closing system, with or without helical guidance, may further comprise a spring or other return member, mounted axially between a bottom wall (forming the lower surface) of the base and the rod. The rod may carry a radial portion, which may be the anchoring part in the case of helical guidance, against which a movable end of the return member bears. The other end of the return member remains fixed and, for example, directly engaged against the bottom wall of the base.

[0031] When a spring is provided, the spring can be compressed in the closed position of the cover, so that the transition from the closed position to the open position is capable of causing the spring to relax, thus causing the transition from the closed position to the open position automatically.

[0032] In a typical embodiment, the opening / closing system further comprises a fixed guide zone, formed by a guide with a substantially cylindrical structure which surrounds the rod. Optionally, the guide zone cooperates with an anchoring part included in or made integral with the rod, at a lower end of the rod, whereby an axial displacement of the cover during rotation around the axis of rotation depends on the displacement of the anchoring part relative to the fixed guide zone, preferably using a lug engaged in a helical rail.

[0033] In one option, the rod and the cover are connected by a hinge or similar means allowing the cover 5 to be tilted, typically without changing the general direction of extension of the rod mounted through the hole in the peripheral edge. The hinge may be chosen from a pin hinge or a ball joint.

[0034] Additionally or alternatively, the opening / closing system may further comprise a rail belonging to the cover and capable of cooperating with an upper part of the rod. Typically, this upper part and the lower end of the rod are distributed (axially) on either side of the hole in the peripheral edge. Preferably, the cover is capable of passing between the closed position and the open position by the thrust, exerted in a radial direction from the front of the cover towards the rear of the cover, thus causing a relative movement, preferably rectilinear, of the rail carried by the cover and the upper part (which is mounted in or on the rail). This upper, external part may be provided with a lug or rigid male member intended to slide in a groove in the rail.

[0035] In options, the opening / closing system comprises a return member, formed in / carried by the rod (for example at its lower end) or interposed between the rod and a bottom wall (forming said lower surface) of the base, the return member being configured to urge the cover towards the open position, typically by urging the upper end of the rod into its distal position relative to the bottom wall of the base. Preferably, a locking device is also provided for locking the closed position of the cover, by axially blocking this cover (which prevents any rise of the rod). Thus, the action or push can simply correspond to an unlocking and the opening of the cover is immediately facilitated under the effect of the return force which raises or deploys the rod (higher), for example under the effect of a relaxation of a spring.During a rotational movement exerted for example at the front of the cover, the rod is no longer immobilized / retracted by the action of the locking device, so that the return member causes the cover to rise and thus automatically move from the closed position to the open position.

[0036] In one embodiment, the locking device may include: - a retaining element, preferably in the form of a clip or insertion tab, formed in the cover, in or adjacent to a contact portion for contact of the cover against the peripheral edge; and - an additional fixing element, preferably in the form of a gripping edge, under which the retaining element is removably engaged in the closed position.

[0037] In embodiments of the container, one or more of the dis- following positions: - the cover forms a push button which rotates with the rod, the rod defining an axis of rotation of the cover (for movement of the cover around the rod). - the opening / closing system comprises a guide, preferably cylindrical, surrounding and guiding the rod, as well as two return members capable of exerting an axial thrust in the same direction. - a first return member is provided mounted in a hollow of the guide to request a rise of the cover via the rod, and a second return member mounted in a cavity of the base. - the second return member has a contracted (or flatter / compressed) configuration to allow downward axial movement of the insert in response to a pushing force of the cover exerted axially from above on the cover, and a deployed configuration to raise the insert to a default axial position when said pushing force ceases. - the cover has an annular contact portion for contact of the cover against the peripheral edge, an inclination being provided in the contact portion at least on the side by which the rotated cover moves away from the upper opening. - a sliding of the contact part on the inclined upper surface of the peripheral edge can be induced on said side by a rotation of the cover. - the trajectory of the rotation of the cover depends on a substantially helical guidance of the rod, enabled by the coupling of the rod with the guide. - the rod has a rail (for example hollowed out in the thickness of the rod) which is formed along the rod, preferably in the form of a groove which extends between an upper end and a lower end (which possibly opens out at the bottom of the rod), supplemented where appropriate by a housing for a lug in an area adjacent to the upper end. - the rail is provided with a helical part in which a lug formed in a generally cylindrical internal face of the guide is engaged, when the cover is rotated. - the first return member and the guide cooperate with the rod, when the lug is positioned at an upper end of the helical part, so that the force exerted by the first return member is exerted at least, when the return force of the second return member ceases, to allow the rod to rotate (via the helical guide) and rise along the guide, thus rotating the cover. - the constraint system comprises the lug belonging to the guide, as well as a housing provided in the continuity of the upper end of the helical part of the rail and forming an elbow with said upper end of the helical part. - the lug is received in the housing in the closed position, knowing that under the effect of the compressing thrust of the first and second springs constituting the first and second return members, the lug is able to be removed (shifted) from the housing and positioned in the helical part of the rail, in particular in its upper part. - pushing the rod against the lug(s) may cause the guide to rotate (slightly rotate) relative to the base and insert. - the guide extends under the peripheral edge, between the insert and the bottom wall of the base. - the first spring or return member is located between a lower end of the rod and the bottom wall of the base. - the second spring or return member is located axially between the space for receiving the cosmetic product and the bottom wall of the base. - the cover can move from the closed position to the open position following the thrust (push-in thrust), exerted downwards on the cover and then released, the thrust being capable of compressing the first spring and the second spring. - the cover and the rod are also capable of being rotated, automatically, by a relaxation of the first and second springs causing a relative movement of the rod rail (in particular the helical part of this rail) with respect to the lug received in the track / guide zone of the rail.

[0038] Optionally, the constraint system comprises two complementary members, one distributed in the cover and the other in the insert, the two complementary members being configured in the closed position to face each other and / or cooperate mechanically, allowing locking of the closed position. The complementary members are mechanical and / or magnetic fixing members. These complementary members which ensure this locking are preferably arranged hidden under a visible external face of the cover.

[0039] Optionally, the two complementary members comprise at least one protuberance formed on the peripheral end of the cover or on the peripheral edge of the insert, optionally on the front side, the protuberance coupling respectively with a corresponding cavity, possibly with complementary shape, on the peripheral edge or on the peripheral end of the cover.

[0040] In one option, the constraint system includes magnetic members with an attraction effect that keeps the lid closed. These magnetic members include at least one magnet and a complementary ferrous material. Typically, the container may include a magnet in the peripheral end of the lid and another magnet in the peripheral edge of the insert. The two magnets may be positioned such that their opposite magnetic faces face each other in the closed position.

[0041] The features set out in the following paragraphs may optionally be implemented. They may be implemented independently of one another or in combination with one another: - the constraint system includes an elastic return member, preferably in the form of a spring which is compressed in the distal position of the rod. - the elastic return member has a first fixed end in axial abutment under the peripheral edge and a second movable end secured to the rod, possibly attached or engaged in abutment against a ring or annular retaining part, this annular part being fixedly attached to the rod or included in the rod. - the insert is made from a single piece. - the peripheral edge constitutes a collar of the insert. - the insert is rigidly fixed to the base, preferably by elastic interlocking, for example by using axial retaining tabs formed projecting from a bottom wall including the lower surface of the base. - the base is made from a single piece. - the opening / closing system comprises a guide zone formed in a guide, for example with a cylindrical structure, interposed and / or extending between the insert and the base and surrounding the rod,). - a lower end of the rod comprises a flat ring or similar retaining portion (e.g. ring of diameter substantially equal to an internal diameter of the cylindrical structure of the guide), so that when passing between the open position and the closed position, the cover is able to remain substantially parallel to the lower surface of the base. - the cylindrical structure is divided into two guide zones, a first guide zone of cylindrical structure extending (downwards) from the peripheral edge of the insert and a second guide zone of cylindrical structure extending (upwards / in the opposite direction) from the bottom portion forming the lower surface of the base. - the first and second guide zones surround the rod by fitting one zone into the other with at least one radial contact between them.

[0042] In embodiments the cover may be hermetically sealed by a sealing system having one or more of the following features: - in the closed position, the sealing system is formed by a bearing surface of the peripheral edge of the cover on a rigid bead of the insert, the bearing surface or support force being exerted by / from the constraint system: a / At the end (lower end) near the base; b / At the end (upper end) near the space / compartment for the product. - in the closed position, the sealing system includes or is formed by a bearing of the peripheral edge of the cover on a rigid bead of the insert, a tensile force being for example exerted by the constraint system at the end near the base, or alternatively a restraining force is exerted at the end, near the space / compartment for the product. - the lid is kept in the closed position by the constraint system. - in the closed position, the sealing system includes or is formed by a bearing of the peripheral end of the cover on the peripheral edge of the insert. - in the closed position, the sealing system includes or is formed by a bearing surface of the peripheral end of the lid on a ring of a cup comprising the cosmetic product and housed in the space of the insert. - in the closed position, the sealing system includes or is formed by a bearing surface of the peripheral end of the cover on an elastomer bead overmolded on the insert. - in the closed position, the sealing system includes or is formed by a bearing surface of the peripheral end of the cover on an elastomer bead added to the insert. - in the closed position, the sealing system includes or is formed by a bearing surface of the peripheral end of the cover on an elastomer cone (or truncated cone) formed on the peripheral edge of the insert.

[0043] According to a particular feature, an elastomer cone or truncated cone is provided formed on the peripheral edge of the insert, for example in the form of an added part.

[0044] According to another aspect, it is proposed to use the container in a larger packaging assembly, the container being detachable from the rest of the packaging assembly. The container can thus be separated for portable use, since it takes up less space (easier for example to fit in a handbag).

[0045] For this purpose, it is proposed to use the container, which is preferably generally cylindrical in shape and typically wider than it is high, as an integral part of a cap closing an opening of a cosmetic product container. The container may form the entire cap. Brief description of the drawings

[0091] [Fig.23] is an exploded perspective view of a container, here of the neck type, which may include a container of the aforementioned type in a closure member having a very small footprint compared to the capacity of the body of the container. Description of the embodiments

[0092] Several examples of non-limiting embodiments are set out below in detail. In the various figures, identical references indicate identical or similar elements. Certain references shown in Figures 1A to 1D have been omitted in the following figures to simplify the illustration.

[0093] As illustrated in Figures 1A to 9F, the container 1 of cosmetic product 41 comprises a base 2 provided with a lower surface 21, for example made in a bottom wall P2, and a peripheral wall 22 extending upwards from the lower surface 21 or at least from the bottom wall. The base 2 thus delimits an interior volume V and can correspond to a covering part, here a single part.

[0094] The container 1 further comprises an insert 3, mounted in the peripheral wall 22 of the base 2, that is to say being typically surrounded by this peripheral wall 22.

[0095] With reference to Figures 1A and 1B, the insert 3 may have a side wall 3a to delimit a receiving space 31. The side wall 3a extends here in an annular manner around a central axis Zl, typically adjoining a peripheral edge 32 of the insert 3. The side wall 3a may be tubular, having an upper axial annular end 3b which forms a junction with the peripheral edge 32 (angled junction as seen in profile / in any view in axial section parallel to the central axis Zl). This type of arrangement of the insert 3 may be adopted independently of the method of mounting or moving the cover 5 which will be described later.

[0096] The upper axial annular end 3b, formed opposite the lower surface 21, delimits the upper opening O, preferably in such a way that the upper opening O extends entirely into the interior volume V (below the level of the top of the peripheral wall 22). As will be described in connection with various embodiments of the container 1, an inclination may be provided in an upper surface S32 of the peripheral edge 32, which contributes to allowing (complete or partial) embedding of a lid 5 coupled / associated with the insert 3, preferably in a non-removable manner or at least without the possibility of losing the lid 5.

[0097] Here, as visible for example in figures 1A to 1D and also in most of the other figures showing the insert 3, the peripheral edge 32, annular, has a generally frustoconical or partly spherical shape limited by two of its parallels, rising radially outwards. In options, it is only the top of this peripheral edge 32, namely the portion forming the upper surface S32, which has this type of geometry.

[0098] With this arrangement of the top of the peripheral edge 32, the upper surface 32 rises radially outwards, from the upper axial annular end 3b, towards a top of the peripheral wall 22. There is provided, in the insert 3, a receiving space 31 or at least one compartment, in which cosmetic product 41 can be placed. The insert 3 is thus typically hollow to delimit the receiving space 31, accessible via an upper opening O. In this non-limiting example, the insert 3 comprises one or more parts distinct from the base 2 and extends internally into the interior volume V: it is not part of the cladding (external cladding) of the container 1.

[0099] The upper opening O is surrounded and here delimited by the peripheral edge 32. The cosmetic product 41 may be included in a cup 4, received in the reception space 31, possibly being fixed / mounted in a removable manner, so as to be able to exit the reception space 31 via the upper opening O.

[0100] The parts 3a and 32, joined at the end 3b forming here an annular junction, can belong to the same part or form a peripheral wall which surrounds the receiving space 31 and which comes into contact with the peripheral wall 22 of the base. Here the peripheral edge 32 is engaged radially, by an external lateral surface, against the internal face of the peripheral wall 22. The peripheral edge 32 can block the annular space / access from above between the annular end 3b and the top of the peripheral wall 22.

[0101] The container 1 also comprises the cover 5, movable relative to the base 2 and to the insert 3, between a closed position, in which the cover 5 prevents access to the cosmetic product 41, and an open position, in which the cosmetic product 41 is accessible.

[0102] In the non-limiting embodiments illustrated in the figures, the container 1 is, in the closed position, of generally tubular shape, for example cylindrical. Optionally, the lower surface 21 of the base 2 as well as the cover 5 may be of circular shape.

[0103] The figures are purely illustrative and other shapes may be provided. In particular, the lower surface 21 of the base 2 as well as the cover 5 could be square in shape, so that the container 1 in the closed position would have the general shape of a cube. In another embodiment, the lower surface 21 of the base 2 as well as the cover 5 could be triangular in shape, so that the container 1 in the closed position would have the general shape of a triangular prism. Roundings and / or elongations (oblong, elliptical section) can also be provided.

[0104] When the container 1 is in the closed position as in the case of [Fig.lA], 2A, 3A, 4A, 5A, 5C, 6A, 7A, 7C, 8A, 9A, 10 to 13 and 19, the peripheral end 51 of the cover 5 rests on the upper surface S32 of the peripheral edge 32 of the insert 3. Here, an internal surface (not visible in the closed position of the cover 5) of the peripheral end 51 can engage against the insert 3, for example by forming an annular axial contact against the upper surface S32. In this configuration, the cover 5 can be substantially flush with the peripheral edge 32 of the base 2.

[0105] The lid 5 of the container 1 covers, here hermetically, the opening O and is kept closed when an associated perpendicular rod 61, passing (axially) through the peripheral edge 32, is in the maximum insertion position, therefore proximal relative to the bottom wall P2 of the container. As will be described later, a push on the outside of the lid 5 makes it possible to overcome a constraint or locking, by moving the lid 5 typically along / in support of the inclined upper surface S32 of the edge, the inclination of this surface S32 being compatible with / favoring a rise of the rod which guides the movement of the lid, this movement then being able to be generally parallel to the plane of the opening O.

[0106] The contact portion PC of the cover 5 for contact against the surface S32 may have a general shape of an annular projection, projecting relative to a more central region of the cover 5 crossed by the central axis ZI in the closed position. The cover 5 may optionally have a maximum thickness, measured parallel to the central axis ZI in the closed position, at such a projection, the remainder of the cover 5 being comparatively thinner. This projection of the contact portion PC may surround an internal depression of the cover 5.

[0107] As can be seen in particular in FIGS. 1A to 9F, the peripheral edge 32 of the insert 3 and the peripheral end 51 of the cover have an inclination on the facing surfaces, which may each be annular in shape.

[0108] In the illustrated examples, the slope is flat / regular. However, in other options, the slope may be curved.

[0109] According to one embodiment, the upper surface S32 of the peripheral edge 32 of the insert 3 and the corresponding counter-surface (internal surface) of the peripheral end 51 of the cover 5 are inclined relative to the peripheral wall 22 of the base 2, preferably at an acute angle.

[0110] With reference to figures 1A and 1B for example, it can be seen that the base 2 has a horizontal bottom wall P2, perpendicular to the central axis Z1, while the surface S32 of the edge 32 rises towards the outside with a slope corresponding to a angle 0 (theta) which may be less than 60°, for example between 4 or 5° and 50°, more preferably between 9 or 10° and approximately 45°. Here, this angle 0 is measured relative to the plane of the upper opening O, which may be a typically horizontal plane when the container 1 rests on its base 2 in a stable manner.

[0111] Optionally, the cover 5 may extend generally parallel to a plane, and may further become thinner as one approaches its circumferential outer edge or similar outer lateral periphery, thereby forming an angle in the inner surface of the cover 5. This angle may be the same as the angle 0 defining the slope of the upper surface S32. This thus results in a complementarity compatible with embedding of the contact portion PC of the cover 5, in the inner volume V and facilitating the obtaining of an axial annular sealed contact between the cover 5 and the upper surface S32.

[0112] According to one embodiment, in the closed position, the inclination of the upper surface S32 of the peripheral edge 32 and that of the internal surface of the peripheral end 51 of the cover 5 are provided such that the slope angle is substantially the same.

[0113] According to one example, the peripheral end 51 of the cover 5 has a wider section than the section of the upper opening O delimited by the upper end 3b. This wider section allows the peripheral end 51 of the cover 5 to come into (annular) contact against the upper surface S32 (with upward inclination) of the peripheral edge 32, in the closed position of the cover 5. Conversely, the part PC of the cover 5 which has the downward inclination can be dimensioned so as to have an external section which does not protrude radially beyond the top of the peripheral wall 22.

[0114] Optionally, the cover 5 may be thickened at its periphery, optionally only at its periphery to form the projection constituting the contact part PC. This example is not limiting and other configurations are possible. For example, the section of the cover 5 at its peripheral end 51 could be thinner / thinner than the rest of the cover 5, which has an advantage in terms of saving material.

[0115] Likewise, the angle 0 for the inclination of the upper surface S32 and / or the angle at the junction of the peripheral edge 32 with the top of the peripheral wall 22, as visible in the figures, are illustrative and adaptations in the angle or in the way of fitting the cover 5 on the upper surface S32 are permitted without fundamentally modifying the way of obtaining closing and opening.

[0116] The container 1 may also comprise a sealing system preventing the cosmetic product 41 from coming into contact with an external environment when the cover 5 is in the closed position. The container 1 includes, in the illustrated embodiments, a system for opening / closing the cover 5, as well as a system for constraint forcing the cover 5 into the closed position. Here, a system for gripping the cup 4? allowing the cup 4 to be removed from the insert 3 in order to allow the container 1 to be refilled with cosmetic product 41, is also provided.

[0117] Generally, the opening / closing system is capable of moving the cover 5 between the open position and the closed position. This expression is understood as the passage of the cover 5 from the closed position to the open position and / or the passage of the cover 5 from the open position to the closed position. The expression “between the closed position and the open position” can also be used with the same meaning.

[0118] The opening / closing system comprises a rod 61, locating a rear of the cover 5 and typically extending parallel to the central axis ZI. In the various figures, the central axis ZI is a vertical axis corresponding to a longitudinal extension direction (Z) in height. The section of figures 1A and 1B for example is made along the main or median plane (XZ) passing through the rod 61. In a non-limiting case, the position of the rod makes it possible to define two halves, possibly identical, distributed on either side of the main plane (XZ).

[0119] The cover 5 may be flat, extending parallel to the plane (XY) as seen in particular in [Fig.lC]. The rod 61, connected to the cover 5, may be elongated along the axis Zl, parallel to the direction (Z), therefore perpendicular to the plane (XY). Furthermore, the aforementioned angle 0 may be measured at the top of the peripheral wall 22, here with reference to the direction XI (along the radial extension direction (X)) which is a direction of the plane (XZ) at which the top or external face of the cover 5 is typically flush with the top of the peripheral wall 22. The external part PE of the cover 5 may be substantially flat or parallel to this direction XI and perpendicular to the extension direction or axis Z2 of the rod 61.

[0120] In some options, the inclination in the surface S32 of the peripheral edge 32 is distributed in two opposite angular sectors which are crossed by the direction axis XL. The other complementary parts of the upper surface S32 may not be inclined in some options.

[0121] With reference to [Fig.lB] or 3B in particular, the rod 61 is mounted on the insert 3 by passing through the peripheral edge 32 via a hole 69. The rod 61 can thus be housed and arranged in a radial spacing between the peripheral wall 22 of the base 2 and the side wall 3a of the insert 3. Thus, it does not interfere with the interior space 31 and can be completely hidden at least in the closed position of the cover 5. The rod 61 thus mounted in the hole 69 of the peripheral edge 32 has an upper part or rod head which protrudes axially from the peripheral edge to allow the rod-cover connection. The connection can be fixed / rigid. More generally, the rod 61 is suitable to cooperate with the cover 5 and guide the movement of the latter when it is opened and when it is closed. Advantageously, the rod 61 extends from the cover 5, here the contact part PC, crossing the peripheral edge 32. The rod 61 occupies the hole 69 of the insert 3 and extends towards the lower surface 21 of the base 2. In one configuration, the rod 61 can extend from the cover 5 to or adjacent to the lower surface 21 of the base 2, when the container 1 is in the closed position.

[0122] The opening / closing system is capable of being actuated by a push from the cover 5. Advantageously, the push is exerted by a finger on the cover 5. In one configuration, the push from the finger is exerted at the front of the cover, i.e. opposite the rod 61 whose connection to the cover 5 locates a rear of the latter.

[0123] Advantageously, the cover 5 may have a slightly curved profile, have a depression (or a geometry with relief(s), with at least one gripping edge), allowing the finger to have a grip to exert the thrust on the cover 5.

[0124] When the thrust is exerted on the cover 5, the cover 5 performs a translational movement induced by the sliding of the peripheral end 51 of the cover 5 on the upper surface S32 of the peripheral edge 32, due to the angle of inclination of the upper surface S32 and the similar or identical inclination of the internal surface (counter-surface) at the peripheral end 51 of the cover 5 constituting the contact part PC. This translational movement further causes a transverse displacement of the rod 61 relative to the lower surface 21 of the base 2, and possibly of the insert 3, which causes the cover 5 to pass between the open position and the closed position.

[0125] The thrust overcomes the constraint system, which can then facilitate the movement of the rod 61 which will typically raise the cover 5 possibly with the help of a return member and / or with a simple guide coupled to the rod, in preferred embodiments.

[0126] Different embodiments of container 1 are more particularly described below. The same reference signs are used to designate identical elements. Identical elements are not described again.

[0127] Reference is now made more particularly to figures 1A to 1D, illustrating a container 1 of cosmetic product 41 according to a first example.

[0128] In this embodiment, the cover 5 comprises the rod 61 as an axis of rotation, which rod 61 extends linearly along the axis Z2 parallel to the central axis Z1. Thus, when the thrust is exerted, the cover 5, in addition to the translational movement, performs a rotational movement around the rod 61. Preferably, the thrust is to be exerted at a front of the cover 5 and in a direction per right-hand pendular (XI) connecting the front to the back of the cover 5.

[0129] The sliding of the peripheral end 51 of the cover 5 on the upper surface S32 of the peripheral edge 32, due to the angle 0 (theta) or common inclination between the insert 3 and the cover 5 in this interface zone, can be induced by the rotation of the cover 5 around the rod 61. The user can have a natural rotational movement to accompany the cover 5 in its rise of the slope constituted by the upper surface S32.

[0130] With reference to figures 1A to 6C, in this type of configuration, the rod 61 and the cover 5 are / belong to a single piece, so that when passing between the closed position and the open position, the rod 61 also rotates around its axis (Z2), in addition to its transverse upward movement.

[0131] Furthermore, the opening / closing means may further comprise a guide zone, more visible in [Fig. 1C]. The guide zone is preferably of generally cylindrical or tubular structure and makes it possible to delimit all or part of a housing for the rod 61 and for a return member such as a spring 71.

[0132] In one configuration, the guide zone can be obtained by using a cylindrical structure 62, tubular or a semi-cylindrical / semi-tubular structure such as comprising two arcuate walls facing each other and drawing the contours of a cylinder. The insert 3 and the base 2 can be connected with an anti-rotation effect by a guide effect connection, without rotation allowed around the axis ZI between these two components 2, 3, thanks to a fitting made off-center.

[0133] The cylindrical structure 62 forming a part of the connection is for example located between the insert 3 and the peripheral wall 22 of the base 2 and surrounds the rod 61. A part 63 of the insert 3 can engage in the structure 62, which allows rotational indexing. This can also make it possible to ensure correct mounting of the insert, without undesirable angular offset.

[0134] In the illustrated example, and as visible in Figures 1C and 1D, such a connection is distributed in two zones, comprising a first guide zone in the form of the cylindrical structure 62, which is here fixed and integral with the base 22, and a second guide zone in the form of a part 63 running along the first guide zone. The first guide zone forms a female part for receiving by fitting or similar insertion the part 63 formed as tabs or as an anchoring projection, integrally formed with the peripheral edge 32 of the insert 3 (on the side opposite the upper surface S32).

[0135] This example is not limiting and the two guide zones 62, 63 can be made differently. Any positioning means comparable to the part 63 with an anti-rotation effect for the insert and capable of surrounding the rod 61 for guiding the latter, preferably provided in the insert 3, can be used. In variants, the engagement anti-rotation of insert 3 can be made elsewhere for fixed mounting in the interior volume V of base 2.

[0136] Here, a structure or first guide zone 62 has been shown which belongs to the insert 3 and is formed by a structure with a substantially circular section or with circular sections, extending from the peripheral edge 32 of the insert 3 downwards. The second guide zone is produced in the part 63 which projects upwards from the level of the bottom wall of the base 2 (and which can be formed by a substantially circular structure). In one configuration, at least one contact this centering is obtained at the level for example of the lower end of the part 63. Advantageously, the guide zones 62, 63 surround the rod 61 leaving a space for a return member (here a spring 71) which is placed between one of the parts 62, 63 and the rod 61.

[0137] The guide zones 62, 63 may be parts added and fixed respectively to the insert 3 and to the base 2 by any suitable means. Alternatively, guide zones 62, 63 may be obtained which may be integral with the insert 3 and the base 2 respectively.

[0138] Furthermore, the guide zones 62, 63 can cooperate with a part 64 of the flat ring type or similar part added / made integral with the rod 61 at its lower end.

[0139] The flat ring 64, an external shoulder or other change of section with similar widening can be arranged at a lower end of the rod 61. Here, the flat ring 64 has an external circumference with substantially the same diameter as the internal diameters of the guide zones 62, 63, so that, when the cover 5 operates a passage between the open position and the closed position, the flat ring 64 guides the rod 61 in its transverse displacement and rotation movements. This guidance restricts for example any possibility of inclination of the rod 61, which implies that the axis Z2 remains substantially parallel to the central axis Z1. The result here is that, in the open position, the cover 5 can remain substantially parallel to the lower surface 21 of the base 2 or at least maintain its general orientation parallel to the plane (XY).

[0140] The term flat ring 64 is used to designate this part, although any other part capable of performing the functions described below may be used in place of a flat ring. Similarly, the rod 61 and the flat ring 64 may form a single part.

[0141] As visible in figures 1A and 1B, the opening / closing system makes it possible to obtain a minimal bulk of the container 1: the elements allowing the passage between the open and closed position are received between the base 2 and the insert 3 and are therefore invisible from the outside of the container 1. This also adds a aesthetic dimension to the whole. In addition, the opening / closing system allows the transition between the open and closed position with a single push, preferably by a finger, which makes the use of the container very pleasant and intuitive for a user.

[0142] In order to prevent the container 1 from being opened accidentally, a constraint system is also provided. This constraint system may comprise a spring 71 positioned around the rod 61 between the insert 3 and the flat ring 64. In the closed position, the spring 61 is here in the relaxed position, so that it exerts pressure on the flat ring 64, which prevents the rod 61 from moving transversely relative to the lower surface 21 of the base 2 without a thrust being exerted.

[0143] More generally, the container 1 may integrate a constraint system, arranged internally in the container 1, and making it possible to urge / constrain the cover 5 towards the closed position by retaining the rod 61 in a so-called proximal position relative to the bottom wall P2 (including the lower surface 21) of the base 2 which is a wall axially opposite the opening or similar access(s) closed by the cover 5. A return member, whether in the form of a spring 71 or other return mechanism, may help to return to the closed position in options.

[0144] In most of the figures, an elastic return member such as a spring 71, for example a helical spring, is included in the constraint system. Of course, any other return member coupled to the rod 61 may be suitable for allowing the rod 61 to be pushed or urged towards the proximal position.

[0145] As can be seen in particular in [Fig.lA], the cover 5 comprises a contact portion PC resting on an upper surface S32 of the peripheral edge 32. The contact portion PC may have, at the rear of the cover 5, an inclined sub-portion which is offset radially inwards relative to the rod 61, (i.e. located closer to the central axis Zl). Such a sub-portion may slide in an annular region of the upper surface S32 surrounding the rod 61 and / or make it possible to contribute to the creation of an annular seal around the upper opening O.

[0146] With reference to [Fig. 1D], an open position of the cover 5 is illustrated with a closure portion 50 offset behind the upper opening O, for example following a thrust exerted on the cover 5 to achieve a rotation greater than or equal to 100° and typically close to 180° as in [Fig. 1D]. This thrust has made it possible to accumulate energy in the return member; this energy may be at least partly restored when the cover 5 is closed.

[0147] Here is illustrated the opening position of the cover 5 with a fully accessible upper opening O (100% offset of the cover 5). More generally, the cover 5 can occupy any opening position sufficient to allow access to the receiving space 31. As in other options described below, the rod 61 may project by an axial distance H, measured parallel to the axis Z2 of the rod 61, which exceeds for example 2 or 3 millimeters, when the cover 5 is brought into an open position. The rod 61 thus extends with an axial spacing above the peripheral edge 32, up to the junction with the closing part 50. The axial distance H may be greater than or equal to the height of the outer surface S32 of the peripheral edge 32.

[0148] Another embodiment of a container 1 is now described, with reference to Figures 2A and 2B.

[0149] The only difference between the first embodiment illustrated by figures 1A to 1D and this second embodiment is that the opening / closing system does not include a guide, i.e. nothing equivalent to the two guide zones 62, 63.

[0150] Thus, when the container 1 moves from the closed position to the open position, the rod 61 is not guided in its transverse movement relative to the lower surface 21 of the base 2. As a result, in the open position, the cover 5 can be inclined relative to the lower surface 21 of the base 2.

[0151] An advantage of this embodiment is that the number of parts is reduced if the guide zones 62, 63 are added parts or that the manufacture of the base 2 and the insert 3 is facilitated since it does not require producing these guide zones 62, 63. In addition, the inclination of the cover 5 in the open position provides an aesthetic and original rendering for the user of the container 1.

[0152] In options, an anti-rotation effect between the insert 3 and the base 2 is obtained by reliefs located in fixing regions (at the bottom and / or at the top) base - insert.

[0153] Figures 3A to 3C illustrate a container 1 according to a third embodiment.

[0154] In this embodiment, the opening / closing system comprises: - a guided part 65 and allowing anchoring of the rod 61; and - a guide zone or guide 66, which predefines the trajectory of the part 65 when moving the cover 5 with its rod 61.

[0155] More generally, the rod 61, which is integral in rotation with the rest of the cover 5, can support an anchoring part 65 which is guided axially and also in rotation by a guide 66. The guide 66 can be produced in the form of a helical relief, for example a groove or a rib, formed in a fixed part of the base 2 and / or of the insert 3.

[0156] The guide 66 defines a guide zone, being here formed by a tubular structure - typically of substantially circular section, extending from the peripheral edge 32 of the insert 3 towards the lower surface 21 of the base 2. Advantageously, the relief corresponding to the guide zone surrounds the rod 61. The guide zone guide has for example at least one rail or helical groove provided on the internal surface of the guide 66 which is here of cylindrical structure and arranged under the region of the edge 32 which includes the hole 69, as visible for example in [Fig.3C].

[0157] The guide 66 may be an added part and fixed to the insert 3 by any suitable means. Alternatively, the guide 66 forming the guide zone may be integrally formed with the insert 3, in a single piece for example.

[0158] The anchoring portion 65 also has a generally cylindrical shape, with an external diameter substantially equal to the internal diameter of the guide 66. With reference to [Fig.3C], a base wall is provided in the cylindrical anchoring portion 65 or a similar section-restricted portion for forming an internal shoulder or similar internal gripping edge. The anchoring portion may extend parallel to the central axis Z1 by extending around the axis Z2, from the base wall to a top / distal end of the bottom wall of the base 2.

[0159] Here, for example, a base wall is provided which is solid and pierced with a hole, so as to be crossed via this hole by a lower end of the rod 61 (end of the rod provided opposite the rod 61 - closure part 50 junction). This base wall faces the bottom wall P2 (forming the lower surface 21) of the base 2, while the upper end of the anchoring part 65 faces axially a bottom of the peripheral edge 32 of the insert 3.

[0160] The anchoring part 65 is mounted in the guide 66 and is movable depending on the associated guide zone. The guidance is for example enabled by the presence of one or more lug(s) 67 cooperating with the rail or helical groove (or along a helical rib). The lug projects radially outward relative to the rest of the tube wall constituting the anchoring part 65. In Figures 3A and 3B, it can be seen that the anchoring part 65 is located at a lower end of the rod 61 while being axially secured to this lower end. The anchoring part may be an intermediate part which allows anchoring of the rod 61, here in the insert 3. In variants, the anchoring part 65 may be included in the part constituting the rod 61 and ensures direct anchoring in the insert 3.

[0161] Given this anchoring of the rod 61, when the thrust is exerted on an external / accessible part of the cover 5 to leave the closed position or conversely to return to the closed position, the rotation and the transverse displacement of the rod 61 cause the movement of the lug(s) 67 in the helical rail. This makes it possible to prevent an excessively rapid rise which could impair the proper functioning of the opening / closing mechanism after repeated uses or insufficient rise of the cover 5, with the possibility of limiting undesirable friction of the contact part PC against the upper surface S32 of the peripheral edge 32 during the rotation of the cover 5.

[0162] In this embodiment, the lower end of the rod 61 is held in the anchoring part 65. As can be seen in FIGS. 3A to 3C, the anchoring part 65 has a hole into which the (lower) end of the rod 61 is inserted. Optionally, the lower end of the rod 61 has a larger diameter than the hole, so that the rod 61 cannot be removed from the anchoring part or part 65. The rod 61 may also have two protrusions engaging in spaces or notches, typically of complementary shapes, of the part 65 which prevent rotation of the rod 61 alone (anti-rotation effect).Thus, for example, the protrusions of the rod 61, formed as external radial projections coinciding with the level of the base wall of the part 65, are engaged in the spaces of the part 65, with possibly a generally square shape / section of these protrusions (section taken in a plane parallel to the reference plane (XY)).

[0163] When the container 1 passes between the closed position and the open position, the rod 61 performs the translational and transverse displacement movements described above. The engagement of the part 65 by the protuberances or similar reliefs of the rod 61 then causes the displacement of the anchoring part 65, and more particularly of the lugs 67 of this part 65 in the helical rail.

[0164] Concerning the spring 71 or equivalent return member of the constraint system, it can be interposed axially between the insert 3 and the anchoring part 65, for example by bearing axially from above on the base wall of the anchoring part 65. It is understood that the spring 71 can be placed between the region of the edge 32 delimiting the hole 69 and the base wall delimiting the hole of the anchoring part 65 (the latter hole being located here directly above the hole 69, these two holes being able to be crossed by the axis Z2).When the container 1 is in the closed position with the constraint system which urges the lower end of the rod 61 in the proximal position of the bottom of the base 2 (here with the spring 71 in its relaxed position, pushing the anchoring part 65 downwards), this prevents any movement of the rod 61 and therefore the passage from the closed position to the open position without a thrust being exerted (no accidental opening, even in the event of a jolt during transport for example).

[0165] The configuration of this third embodiment, independently of the design precisely chosen for the constraint system, reinforces the guidance of the rod 61 during the passage between the open position and the closed position.

[0166] In this embodiment, in the open position, the cover 5 can be kept parallel to the lower surface 21 or bottom wall P2 of the base 2. More generally, a helical guide produced at the level of a rod portion inserted under the edge 32 can accompany the desired movement for the cover 5, which is typically a movement which remains substantially parallel to the plane (XY), that is to say transverse to the central axis Z2 which passes through the upper opening O.

[0167] Figures 4A to 4C illustrate a fourth embodiment.

[0168] In this embodiment, the guide zone of the opening system does not comprise a helical rail but at least one lug 67 is provided in the guide 66 which can be designed as a sub-part of the insert 3, in the same part for example. In this embodiment, the guide 66 is also of cylindrical structure and prevents the rod 61 from tilting / changing direction relative to the axis Z2 around which the cover 5 can rotate. Although the guide zone is here made integrally with the insert 3, a design by assembling different parts may also be suitable.

[0169] The rod 61 has a helical rail cooperating with the lug 67 of the guide 66. The rail may correspond to a groove which extends at least 180° around the axis Z2. The rotation of the cover 5 to 180° is clearly visible in [Fig.4B], with the contact part PC fully raised above the peripheral wall 22.

[0170] Thus, when the thrust is exerted and the container 1 passes between the open position and the closed position, the rotation and the transverse displacement of the rod 61 follow the shape of the helical rail, due to the lug 67 of the guide 66 which cooperates with the helical rail (here by inserting itself into the groove). The groove shown in [Fig.4C] can open axially from the bottom, to allow assembly with insertion of the lug 67, when the rod 61 of the cover 5 is fitted into the guide 66 by passing through the hole 69.

[0171] In this embodiment, the constraint system comprises the lug 67 of the guide 66 as well as the rod 61. More particularly, the constraint is obtained by tightening the rod 61 and the lug 67. In addition, indexing of the closed position, preferably with a locking effect, can be enabled by providing a cavity or a relief with a gripping edge 39 on the peripheral edge 32, here on its upper surface S32. The contact portion PC of the cover 5 may have a complementary projection or relief which engages, for example in an elastically deformable manner, in / against the relief 39.

[0172] This embodiment has the advantage of a reduced number of elements forming the opening / closing and constraint systems. This therefore facilitates the manufacture of the container 1, while having minimal bulk.

[0173] Figures 5A to 5D illustrate examples in accordance with a fifth embodiment of a container 1 according to the invention.

[0174] The fifth embodiment differs from the first embodiment in that a material of the rod 61 is flexible. The rod 61 may for example be deformed and / or be provided with a hinge. Thus, with reference to FIGS. 5A and 5B, when the container 1 passes between the open position and the closed position, the rod 61 bends due to the angle formed between the plane of the cover 5 (the latter being raised at an angle along the upper surface S32 of the peripheral edge 32) and the peripheral edge 32. The slope or inclination provided at the rear of the contact part PC, once rotated - for example at 180° as in [Fig.5B], no longer corresponds to the inclination of the upper surface S32 allowing the cover 5 to remain perpendicular to the axes Z1 and Z2. This is why the cover 5 tends to rise obliquely on the rear side relative to the insert 3.

[0175] A variant of this embodiment is illustrated in Figures 5C and 5D. Here, the section of the rod 61 at its junction point with the cover 3 is thinned / thinner than the rest of the rod 61. A part of the rod 61, possibly with a rigid part or ring 64 added, remains axially guided here, so that the rod 61 remains aligned with respect to the hole 69, as in the case of Figures 5A and 5B.

[0176] Advantageously, the top of the rod 61 with a thinning allows greater flexibility of the rod 61 to obtain a hinge effect. Thus, the appearance of stress potentially applied to the junction point between the rod 61 and the closure part 50 of the cover 5 is avoided when the container 1 passes between the open position and the closed position. Instead, the closure part 50 rises as the cover 5 and the rod 61 slide upwards, overcoming the stress exerted by the return member, here in the form of the spring 71.

[0177] In other variants, this flexible arrangement of the top of the rod 61 can be adopted with other guide structures, if necessary with a helical rail. If necessary, the upper surface S32 or the top of the wall 22 can have a specific projection or geometry at the rear of the container 1, allowing the raising effect of the closing part 50 only in the event of overlap between the cover 5 and the rear of the rest of the container 1

[0178] The sixth embodiment of the container 1 is illustrated in Figures 6A to 6C.

[0179] In this embodiment, the opening / closing system comprises the part anchor 65 and the guide 66 which forms a guide zone, here helical.

[0180] As in the third embodiment, the guide zone is formed by a rigid guide (or fixed relative to the insert 3) with a substantially circular structure, extending from the peripheral edge 32 of the insert 3 towards the lower surface 21 of the base 2. Advantageously, the guide zone produced by the guide 66 surrounds the rod 61. The guide 66 has at least one helical rail, here a groove, on its internal surface.

[0181] The guide 66 may be one or may include a part attached and fixed to the insert 3 by any suitable means. Alternatively, the guide 66 may be entirely included in a constituent part of the insert 3, without assembly of different parts.

[0182] The anchoring portion 65 may also have a generally cylindrical shape. or adapted to maintain an axial orientation of the rod 61, parallel to the axis Z2. Here, the part 65 has an external diameter substantially equal to the internal diameter of the guide 66. A radial wall of the part 65 is provided with an axial hole directly above the hole 69, here on the top of the anchoring part 65. The anchoring part 65 is hollow to allow all or part of a return member such as a spring 68 to be housed.

[0183] Unlike the embodiment of Figures 3A to 3C, the cavity of the guide 65 opens out from the bottom, with an axial opening which faces the bottom wall P2 of the base 2, while the solid radial portion of the anchoring part can face the peripheral edge 32 of the insert 3. It can be noted that the anchoring part 65 can be of a design similar or identical to that shown in the third embodiment but arranged upside down in another direction of the axis Z2.

[0184] The anchoring part 65 is mounted in the guide zone of the guide 66 and may comprise a lug 67 projecting radially outwards cooperating with the helical rail (typically mounted via a lower axial outlet of a helical groove constituting this rail). Thus, when the thrust is exerted and the container 1 passes between the open position and the closed position, the rotation and the transverse displacement of the rod 61 cause the movement of the lug 67 in the helical rail.

[0185] In this embodiment, the lower end of the rod 61 carries the anchoring part and, once the anchoring part 65 is mounted in the guide 66. The assembly can vary. The fixing at the hole of the guide part 65 can be provided as in the case described for the third embodiment.

[0186] As can be seen in Figures 6A to 6C, the section of the rod 61 formed from the closure part 50 may be shorter than in the third embodiment. Indeed, the anchoring part 65 may here extend the rod 61 axially (downwards).

[0187] This allows space to be provided in the cylinder or guide 66 in order to place a spring 68 or other return member, possibly of the magnetic type. More precisely here, a spring 68, for example helical, is received in the guide by being housed (at least in part) in a tubular / cylindrical section of the anchoring part 65. The spring 68 extends from the bottom wall of the base 2 to the lower end of the rod 61, received in the hole of the guide 65, the spring having a movable end bearing on the radial portion of the anchoring part 65.

[0188] In the closed position and as seen in [Fig.6A], the spring 68 is in a state of compression, so that it forces the rod 61 and the guide 65 upwards. This force cannot be exerted in the closed position due to the presence of a locking device which is part of the constraint system.

[0189] The constraint system here comprises fitting or locking means (76, 77) placed for example at the front in this non-limiting case. Such means will be described in more detail with reference to [Fig. 12]. These fitting means make it possible to lock the cover 5 relative to the insert 3, to maintain the closed position despite the return effect which tends to make the cover 5 rise. These fitting means can be unlocked by the pressure exerted on the cover 5.

[0190] When the fitting means are unlocked by the thrust exerted on the cover 5, the spring 68 passes into its rest position which causes the cover to open automatically. When moving from the closed position to the open position, the rod 61 performs the translational and transverse displacement movements described above. The protrusions of the rod 61 then cause the guide 65, and more particularly the lugs 67, to move in the helical rail. More generally, the rod 61 with its anchoring part 65 forms a slide assembly which is by default in the high position in the guide 66, in the absence of any action to maintain / lock the closed position.

[0191] A seventh embodiment is now described with reference to Figures 7A to 7D.

[0192] The difference between this seventh embodiment and the first embodiment is that the rod 61 and the closure part 50 of the cover 5 are not integral. In other words, the rod 61 can be produced in the form of a separate part before assembly. Here the assembly allows the closure part 50 to be made integral with the rod 61, in particular at least integral in axial translation along the axis Z2 so that a rise of the rod 61 allows a rise of the cover 5 as a whole.

[0193] In the option illustrated in Figures 7A and 7B, the rod 61 and the cover 5 are fixed to each other by a hinge connection 52, for example a pin hinge.

[0194] In the variant illustrated in Figures 7C and 7D, the rod 61 and the cover 5 are fixed to each other by a ball joint 53. These connections 52, 53 allow the cover 5 to move back and forth (the rod 61 locating the rear) by the rotation of the rod 61 which is typically guided in its housing. These connections 52, 53 are compatible with a movement path of the cover 5 which is maintained transverse to the axis Z2, but allowing a movement as soon as the cover 5 is located at the rear of the container 1.

[0195] Thus, when the container 1 moves from the closed position to the open position, the hinge 52, 53 also allows the cover 5 to move by pivoting relative to the rod 61. Typically, as seen in [Fig.5B], when the container 1 is in the open position, the cover 5 can be inclined relative to the lower surface 21 of the base 2, thus leaving an arrangement perpendicular to the axes Z1 and Z2.

[0196] These options make it possible in particular to reduce the stress potentially applied to the junction region between the rod 61 and the cover 5 during the passage of the container 1 between the open position and the closed position.

[0197] A return effect has been illustrated here which forces the rod 61 towards its low / proximal position of the bottom wall P2, to facilitate obtaining the closed position. Of course, it is also possible to provide a default return towards the open position and, in this case, axial locking of the closed / lowered position of the cover 5 can possibly be achieved by a suitable locking device.

[0198] An eighth embodiment is illustrated in Figures 8A and 8B.

[0199] In this embodiment, the opening / closing system also comprises a cover 5 supported by a rod 61, but with in addition a rail 109, provided on the (internal) face of the cover 5 facing the insert 3. Advantageously, the rail 109 can be substantially rectilinear, being able to run between two diametrically opposite ends. For example, the rail 109 can extend from the front to the rear of the cover 5. It can typically be an integral part of the part constituting the cover 5.

[0200] The rod 61 and the cover 5 are two separate elements in this embodiment. A portion of the rod 61 is received in the insert 3, axially through the hole 69. The rod 61 extends towards and for example up to (in the closed position) the bottom wall forming the lower surface 21 of the base 2. The rod 61 comprises a portion 61A extending beyond the hole 69 of the insert, called the external portion. The part 61A of the rod 61, here in the form of an external bent part as visible in [Fig.8B], includes a male member engaged in an elongated cavity, from front to rear, delimited between two parallel sides of the rail 109. This male member of the part 61A is slidably mounted in the elongated cavity, parallel to the closing part 50 of the cover 5 and can advantageously form a right angle with the rest of the rod 61 which extends in the direction of the axis Z2.

[0201] The end of the part 61A of the rod 61 may form a lug or comparable male member engaged in the rail 109, the rail 109 here being arranged in the form of a profile or a furring which delimits a rectilinear groove. In variants, the rail is formed in the thickness of the cover 5 without forming an internal relief. Return wings 109' of the rail 109 are optionally provided for axial retention of the lug or male member, so that the latter can cooperate in / slide in the rail 109 for the passage between the closed position and the open position.

[0202] According to this embodiment, to move the container 1 from the closed position to the open position, the thrust is to be exerted at the front of the cover 5, but in a radial direction (directed towards the rear), as illustrated for example by the arrow F8 in [Fig.8A]. In particular, the thrust is to be exerted typically from the front of the cover 5 towards the center of the cover 5.

[0203] The thrust causes the cover 5 to move relative to the rod 61, due to the displacement of the rail 109 guided by the lug or comparable male member in the part 61 A. This movement also induces the transverse displacement of the rod 61 relative to the lower surface 21 of the base 2, due to the sliding (with rising effect) of a part of the peripheral end 51 of the cover 5 on the peripheral edge 32 of the insert 3, in a manner analogous to that described above.

[0204] Furthermore, in order to avoid untimely passage from the open position to the closed position, a locking effect can be obtained by a clamping and / or retaining means 109a associated with the rail 109. For example, the rail 109 has a reduction in section / width, therefore a passage for the lug locally smaller and slightly less than the width of the lug 110 at its end in contact with the lug 110 in the open position (as visible in [Fig.8B] for example), which makes it possible to obtain end-of-travel clamping. The cover 5 can be inclined significantly, following the inclination of the upper surface S32 in the region adjacent to the hole 69. In this option, the rod can be rigid 61, without a folded / flexed area. An anti-rotation effect of the rod 61 may be provided, or at least the rotation of the rod may be limited to a small angle, for example less than 5 or 10°.The bottom of the rod 61 (in the rod or in an attached part) may, if necessary, have a flat or a relief with an anti-rotation effect.

[0205] Optionally, the interior space 31 delimited by the insert 3 may be off-center relative to the wall 22, for example so that the front end of the cover 5 in the open and locked position does not interfere with access to the product 41 via the upper opening O. In this case, an upper surface 32 has been illustrated which borders only a part of the upper opening O or may have a variable spacing relative to this upper opening O. Such an option is applicable in most of the other options illustrated elsewhere.

[0206] In this embodiment, the constraint system also comprises a return member, for example with the spring 71 and a retaining means (here the flat ring 64) of the movable end of the return member, as described above with reference to the other embodiments.

[0207] Figures 9A to 9C illustrate a ninth embodiment of a container 1 according to the invention.

[0208] In this embodiment, the opening / closing system comprises the rod 61 and the cover 5. It further comprises a guide zone, here in a rigid guide 66, which is distinct from the insert 3 and for example adjacent to the latter. Optionally, this guide 66 has a cylindrical shape surrounding the rod 61. In an exemplary embodiment, the internal diameter of the guide 66 forming the guide zone is substantially equal to the external diameter of the rod 61.

[0209] The guide 66 may have at least one lug 67, cooperating with a rail 111 provided on the rod 61, as visible in FIGS. 9D to 9F. Two lugs 77 diametrically opposite may be provided. The guide 66 is axially locked between the base 2 (from below) and a portion of edge or relief of the insert 3, for example directly by the peripheral edge 32 of the insert 3 in a portion adjacent to the hole 69 and typically offset radially inwards relative to the hole 69.

[0210] Typically, a depression in the peripheral edge 32, forming a hollow opening downwards, receives the top of the guide 66 in: - forming an axial stop zone from above by cooperating with an edge portion 66b of the guide 66, this edge portion 66B possibly extending on the inner side relative to the rod 61 (radially between the axis Z1 and the axis Z2) and which has two extreme edges delimiting an upper notch 66e of the guide 66; and - blocking the rotation of the guide 66 beyond a certain threshold, for example to limit the rotation to approximately 20° or a little less, by forming stops against which the extreme edges bear. The axial spacing E can then be obtained only at the level of the notch 66e, further back than the rod 61.

[0211] Alternatively or in addition, the base 2 opposes an axial rise of the guide 66, for example by engaging against a complementary relief located at a distance from the top of the guide 66. As described below, in the closed position (visible in [Fig.9A]) an axial spacing E is provided between the peripheral edge 32 and the top of the guide 66 to allow a combined depression of the cover 5 and the insert 3 in the direction of the bottom wall P2 of the base 2.

[0212] The opening / closing system may here comprise a first return member, for example a first spring 112, located between the lower end of the rod 61 and the lower surface 21 of the base 2. Other arrangements of such a return member are permitted to bias the rod towards an extension configuration in which the rod is distal from the bottom wall P2 of the base 2. For example, the rod may integrate a repulsion magnet and / or a compressible member in its lower end. The opening / closing system also comprises a second return member, for example a second spring 113 located between the lower surface 21 of the base 2 and the insert 3, under the space 31 for receiving the cosmetic product 4L. In this embodiment, the insert 3 is thus movable relative to the base 2.

[0213] In the closed position, the first spring 112 is in a compressed state, so that it exerts upward pressure on the rod 61. The second spring 113 is in a relaxed state. The axial retention of the rod 61 can be achieved under the peripheral edge 32, for example by a stop element provided in the guide 66

[0214] To move the container 1 from the closed position to the open position, the thrust is to be exerted (by the user) on the external face of the cover 5 and downwards ([Fig.9B], see arrow F9 reflecting the direction of the thrust). The thrust then forces the first spring 112 in a further compressed state and also compresses the second spring 113. The thrust also makes it possible to unlock the constraint system, described in more detail below, which then no longer constrains the container 1 in the closed position.

[0215] Then, as visible in [Fig.9C], the opening with access to the product 41 is caused automatically by the first spring 112 which passes into its relaxed state, driving the rod 61 in the transverse movement relative to the lower surface 21 of the base. The lug 67 of the guide 66 is engaged in a helical part 61h of the rail 111 (here a groove) of the rod 61, guiding the rod in a rotational movement which also drives the cover 5 in rotation around its axis of rotation (therefore around the axis Z2 which is also a central axis for the guide 66). In the open position, the second spring 113 returns to its relaxed position. The second spring 113 therefore allows the displacement and automatic replacement of the insert 3 relative to the base 2.

[0216] Furthermore, cleats or axial stop reliefs R2, R3 may be provided on the base 2 and / or the insert 3. For example, the base 2 has at least one fixed relief R2, possibly projecting radially inwards from the internal face of an internal wall delimiting a cavity C2 for receiving the member forming the second spring 113. This fixed relief R2 may form an axial stop engaged from below by a complementary part or adapted relief R3 of the insert 3, provided in an anchoring bottom of the insert which penetrates into the cavity C2. The relief R3 is thus adapted to be placed in an external groove 115 provided on the base 2, under the relief R2. More generally, any coupling adapted for limited sliding of the insert 3 in the base 2 may be provided, with the cover 5 embedded in the internal volume V.The movement of the insert 3 relative to the base 2 is thus controlled, without risk of dismantling the insert 3, preferably with axial guidance of the insert 3 thanks to the peripheral edge 32 which runs along the internal face of the peripheral wall 22.

[0217] In this embodiment, the constraint system is distributed in the guide 66 which includes for example one or two lugs 67 and in the rod 61, at the level of a part of the rail 111. The constraint system is more particularly illustrated in FIGS. 9D to 9F which are enlarged views of the rail 111 with its helical part and of the lug 67.

[0218] [Fig.9D] illustrates the constraint system when the container 1 is in the closed position. A housing 11 IA is provided in the continuity of an upper end of the helical part of the rail 111 and forms an elbow with this upper end of the helical guide zone. The lug 67 of the guide 66 is received in the bottom of the housing 11 IA, the top of the housing 1 IA corresponding to the tip of a section of track in the shape of an inverted “V”. By thus occupying the bottom of this housing 111A (under the tip / upper end of the guide zone), the lug 67 is not engaged in the helical part 61h of the rail 111. The inverted V shape implies that in the event of the rod 61 descending, a relative rotation is necessary between the rod 61 and the guide 66, the latter being mounted mobile in rotation in the base 2.

[0219] During the push from above ([Fig.9E]) which lowers the cover 5 with the rod 61, the cylindrical structure forming the guide 66 is forced to rotate, due to the lug(s) 67 received in the housing 11 1A of the rod 61. This rotation is advantageously quite small, for example the cylindrical structure forming the guide 66 rotates between 10 and 20°, for example greater than 12 or 15°. This rotation allows each lug 67 to be placed as high as possible in the corresponding rail 111, facing the upper end of the helical part 61h and thus be engaged there.

[0220] Then, when the thrust is released, the lug(s) 67 no longer occupy the same (short) branch of the corresponding rail 111, which allows the action of the first return member, here the spring 112. The container 1 can move into the open position ([Fig.9F]), due to the rotational and transverse displacement movements of the rod 61, the movement of the rod 61 being guided by the coupling(s) between the helical part 61h and the corresponding lug 67 engaged therein. The helical part 61h can be configured to limit the rotation to approximately 180° around the axis Z2. Returning to the closed position may require a simple rotation of the cover 5, here also with a helical guiding effect but overcoming the restoring force exerted at the bottom of the rod 61. The inclined upper surface S32 may optionally promote the engagement of the lug 67 in the short branch of the rail 111 forming the housing 111 A, for example by participating in the end of the guiding..

[0221] Figures 10 to 13 illustrate alternative embodiments of constraint systems. These alternative embodiments can be applied to all embodiments, and can be combined with each other. These alternative embodiments can also be used in combination with the embodiments of the constraint systems described above with reference to Figures 1A to 9F.

[0222] In the examples illustrated in Figures 10 to 11, the visible constraint system is the system comprising the flat ring 64 and the spring 71. This is not limiting and represents only an example of implementation.

[0223] In [Fig. 10], the constraint system may further comprise means for locking the cover 5 to the insert 3. The locking means comprise a protrusion 73 on the peripheral end 51 of the cover 5 or on the peripheral edge 32 of the insert 3, coupling respectively with a cavity 74 on the peripheral edge 32 of the insert 3 or on the peripheral end 51 of the cover 5.

[0224] These locking means allow, in addition to locking the cover 5 on insert 3, to indicate the end of travel to the user.

[0225] In the example of [Fig. 11], the constraint system comprises other means for locking the cover 5 to the insert 3 comprising magnets, here a pair of magnets 75, or similar complementary magnetic members. One magnet 75 is provided in the peripheral end 51 of the cover 5 and the other magnet is provided in the peripheral edge 32 of the insert 3, so that they are invisible from the outside, at least in the closed position.

[0226] The opposite faces of the two magnets 75 face each other, so as to be attracted to each other in the closed position. The use of a pair of complementary magnets 75 also makes it possible, in addition to locking the cover 5 on the insert 3, to indicate the end of travel to the user.

[0227] In the example of [Fig. 12], the constraint system comprises means for locking or fitting the cover 5 and the insert 3. More precisely, the locking or fitting means may be provided at the front of the cover 5. These means comprise, for example, a clip 77 or other retaining element in the peripheral end 51 of the cover 5, capable of fitting into a complementary fixing element 76 in the closed position, here in a complementary gripping edge (for clipping) provided in the peripheral edge 32 of the insert 3.

[0228] [Fig. 13] illustrates the same constraint system but in which two means for fitting the cover 5 and the insert 3 are used, respectively one at the front of the cover 5 and another at the rear of the cover 5. A radial tab of the cover 5 projects radially outwards to fit or be inserted into a groove provided in the upper surface S32, here provided for example further back than the rod 61.

[0229] Figures 14 to 21 illustrate different embodiments of a sealing system of the container 1, making it possible to define an annular sealing contact in a hidden area in the closed position. These options can be applied to all embodiments, and can be combined with each other. These options can also be used in combination with the embodiments of the containers and the constraint systems described above with reference to Figures 1A to 13.

[0230] Advantageously, the sealing system options / variants may operate in conjunction with a constraint system. Indeed, the constraint systems make it possible to exert a force on the cover 5 in the closed position, this force typically being directed downwards and therefore keeping the cover 5 pressed and relatively under pressure on the insert 3.

[0231] In the examples illustrated in Figures 13 to 21, the visible constraint system is the system comprising the flat ring 64 and the spring 71 or any similar return member arranged to urge the rod into the proximal position of the bottom of the base 2. This is not limiting and represents only an example of implementation.

[0232] According to the embodiment of [Fig. 14], the sealing is achieved by a cone-shaped bearing surface on a rigid ring. More precisely, the peripheral end of the cover 5 is assimilated to the cone, for example by forming a frustoconical projection, and the rigid ring is produced by / in the angle formed between the side wall 3a of the insert delimiting the receiving space 31 and the peripheral edge 32. The bearing surface is increased by the force applied by the constraint system on the cover 5. It is understood that the sealing is enabled by an annular contact which is exerted axially, while also being able to include a radial component thanks to the radial support towards the inside of the ring, against the contact part PC which is here sloping / inclined.

[0233] According to the embodiment of [Fig. 15], the seal is achieved by a cone-on-cone surface. More precisely, the peripheral end 51 of the cover 5 is assimilated to a first cone (in the contact part PC also shown in other drawings such as [Fig.lA] for example) and a second cone is formed by the peripheral edge 32 of the insert 3. The surface is increased by the force applied by the constraint system on the cover 5. In this example, the constraint system further comprises the locking means 73, 74.

[0234] According to the embodiment of [Fig. 16], the sealing is achieved by a cone-on-ring bearing surface. More precisely, the peripheral end 51 of the cover 5 is assimilated to the cone and the ring is the upper end of a cup 4 running along the side wall 3a of the insert 3. The bearing surface is increased by the force applied by the constraint system on the cover 5.

[0235] According to the embodiment of Figures 17 and 18, the seal is achieved by a cone-shaped bearing surface on an overmolded elastomer ring 81 or 82, respectively. More precisely, the peripheral end of the cover 5 is assimilated to the cone and the elastomer ring 81 or 82 is overmolded on the peripheral edge 32 of the insert 3. The bearing surface is increased by the force applied by the constraint system on the cover 5. It is understood that a part of the upper surface S32 is here formed by the added or overmolded annular portion.

[0236] According to the embodiment of [Fig. 19], the seal is achieved by a cone-on-cone elastomer bearing surface 32b. More precisely, the peripheral end of the cover 5 is assimilated to the cone and the elastomer cone 32b is attached in the form of an intermediate part between the insert 3 and the cover 5. The elastomer cone 32b is for example attached to a rigid part 32a of the peripheral edge 32, here over an entire annular part 32a forming a portion of the insert 3 which supports the cone 32b. The elements 32a and 32b together form the peripheral edge 32. The bearing surface is increased by the force applied by the constraint system on the cover 5. In this example, the upper surface S32 is only formed by the material of the frustoconical element called “elastomer cone” 32b. It is understood, as a variant, that just an annular portion of the upper surface S32 may be formed by the added or overmolded annular portion.

[0237] According to the embodiment of [Fig.20], the seal is achieved by a cone-on-ring bearing surface 84 of the upper surface S32. Here, the peripheral end of the cover 5 is thus assimilated to the cone and the ring 84 can be formed by a bead provided on the peripheral edge 32 of the insert 3. The bearing surface is increased by the force applied by the constraint system on the cover 5.

[0238] According to the example of [Fig.21], the seal is shifted further outwards, achieved by a cone-on-ring bearing surface 85. More precisely, the peripheral end of the cover 5 is assimilated to the cone and an overmolding 85 or similar outer overlayer of the base 2 can be provided. Thus, the overmolding 85 of the base at the upper end of the peripheral wall 22 of the base 2 forms the ring. The cover 5 bears radially from the inside against the top of this overlayer, so that the outermost edge does not protrude beyond the top of the base thus overmolded, with a flush effect of the cover 5. The bearing surface is increased by the force applied by the constraint system on the cover 5.

[0239] [Fig.22] illustrates an example of container 1 with the lid 5 open, in an option with a system for gripping the bucket 4, transposable to various embodiments including those previously described.

[0240] At least one depression adjacent to a side wall of the cup 4 is provided here, this depression being formed in the insert 3 or in the peripheral edge 32. This creates a gripping zone 91 with access to the side wall of the cup 4. Preferably, the gripping zone is distributed in two regions allowing the insertion of at least two fingers able to grip the cup 4 between them, which is for example of the clippable / nestable type in the space 31.

[0241] In embodiments, the peripheral wall 22 may form the external lateral face of a closure member 8 (cap for flask / bottle for example; see [Fig.23]) or, alternatively, be embedded in an external casing of such a closure member 8.

[0242] The container 1, of cylindrical or non-cylindrical external shape, may constitute all or part of a cap or comparable closure member 8 closing an opening 7 of a container 80 of cosmetic product or of any packaging assembly larger than the container 1. The container 80 has a body 80c whose side wall extends upwards from a bottom 80a, the opening 7 being able to be formed on the top of the container 80, for example at the level of a neck or neck 80b.

[0243] An RF attachment region may be provided in the cap 8 to enable removably attaching to a lateral outer face of the neck 80b, the attachment preferably being actuated by rotation about an axis of the container 80 which may be confused with the central axis Zl. An oblong or non-circular shape of the plug 8 may be adopted in certain embodiments.

[0244] The cover 5 may optionally be offset radially inwards by a certain distance, for example greater than 3 mm, relative to a grippable lateral portion of the cap, which may make it possible to avoid interference between the connection / disconnection of the cap 8 on its container and the force or thrust to be exerted on the cover 5 to obtain the opening of the container 1. Optionally, the cap 8 has a closure portion and a gripping portion which belong to a subassembly of the cap 8 which is separable from the container 1, for example by forming a hollow or insertion housing L of the container 1. Thus, the container 80 can remain closed when the container 1 is extracted for use, if necessary for nomadic use.

[0245] The present disclosure is not limited to the embodiments described above, only by way of example, but it encompasses all the variants that may be envisaged by those skilled in the art within the framework of the protection sought. For example, a base 2 has been described made in a single piece forming an external covering of the container 1. In variants, the base 2 may result from the assembly of two complementary shells or parts, possibly attached in a non-removable manner.
