This application claims priority to French Application No. 2400508, filed Jan. 18, 2024, and to French Application No. 2307669, filed Jul. 18, 2023, the contents of both of which are incorporated herein by reference in their entireties.
The invention concerns a receptacle for a product, in particular a cosmetic product.
To close a receptacle comprising a pot and a cover, it is common practice to screw the cover onto the pot. In such a case, the cover is positioned on the pot in a high position, at a given angular location corresponding to that where the threads of the cover engage with the threads of the pot, and the user then screws it down to a low position of the cover corresponding to a closed position of the receptacle. One disadvantage of this solution is that the effort required is sometimes too great, particularly for people who have difficulty exerting a movement of screwing or unscrewing.
Bayonet-type closing movements are also known, wherein an axial movement is followed by a rotation. At the end of this movement, shapes of the cover are in contact with shapes of the pot to keep the cover closed. However, the area of contact between these shapes may not exceed a certain angular extent, otherwise the shapes used would conflict with each other during the closing movement. The contact area therefore remains limited. On the other hand, the angular amplitude to reach the closed position of the receptacle is relatively large.
While a limited-quality closure may be sufficient for powder cosmetic products, it is not satisfactory for more fragile products such as cosmetic products in the form of cream or liquid.
The purpose of the invention is to overcome at least some of the above disadvantages and to this end proposes a receptacle for a product, in particular a cosmetic product, said receptacle having an axis, referred to as longitudinal axis and comprising a pot and a cover of said pot, said pot having first radial protrusions as well as second radial protrusions, that are at least axially offset relative to the first protrusions of the pot, said cover having first radial protrusions and second radial protrusions that are at least axially offset relative to the second protrusions of the cover, said first protrusions of the pot and/or of the cover extending over a first portion of a circumference of said receptacle, said second protrusion of the pot and/or of the cover extending over a second portion of a circumference of said receptacle, said first and second protrusions being configured to cooperate with each other so as to obtain first and second contact areas respectively, on the one hand, between the first protrusions of the pot and the first protrusions of the cover and, on the other hand, between the second protrusions of the pot and the second protrusions of the cover in a closed position of said receptacle.
Thus, in the closed position, the first protrusions form a first row of protrusions located substantially at the same first level along the longitudinal axis of the receptacle, on the one hand, on the pot and, on the other hand, on the cover. Similarly, the second protrusions form a second row of protrusions located substantially at the same second level along the longitudinal axis of the receptacle, on the one hand, on the pot and, on the other hand, on the cover.
The axial offset between the protrusions of the first row and those of the second row is configured so that the protrusions of one row angularly complement those of the other row, creating a space for the protrusions of one row of the cover between two rows of the protrusions of the pot.
In this way, even if the protrusions of the same row are angularly discontinuous, the angular span of the contact areas between the protrusions of the first row combine with that of the contact areas between the protrusions of the second row, to form an overall contact area without causing areas of conflict between the protrusions.
According to a first preferred aspect of the invention, said first and second contact areas extend cumulatively over more than 180°, or even over more than 270°, said receptacle comprising a seal, said seal being configured to be compressed between said pot and said cover at least in said closed position.
This provides an improved sealing, without the need for screwing, or at least without the need for screwing over the entire stroke of the cover along the longitudinal axis of the receptacle. As the contact areas extend over a large proportion of the periphery of the receptacle, the seal is compressed more homogeneously.
According to another preferential aspect of the invention, which may or may not be combined with the previous one, said first and second protrusions are configured so as to engage respectively against each other to close the receptacle according to a movement referred to as a bayonet movement, comprising at least one rotation about said longitudinal axis, said rotation being less than a cumulative angular amplitude of a first and of a second of said protrusions adjacent to the pot and/or than a cumulative angular amplitude of a first and of a second of said protrusions adjacent to the cover.
This means that the cover may be closed with a rotational movement of the cover having a limited angular amplitude.
According to various additional characteristics of the invention, which may be taken together or separately and which form as many embodiments of the invention:
The invention will be better understood, and other purposes, details, characteristics and advantages thereof will become clearer in the course of the detailed explanatory description which follows, of at least one embodiment of the invention given by way of purely illustrative and non-limiting example, with reference to the appended schematic drawings among which:
As illustrated in
Said receptacle has an axis X referred to as longitudinal axis. It comprises a pot 2 and a cover 4 for said pot 2. Said pot 2 has here a substantially cylindrical shape with a bottom 6 and a lateral wall 8 extending from said bottom 6 along said longitudinal axis X. Said cover 4 has an upper wall 10 and a lateral skirt 12 extending from said upper wall 10 to co-operate with the lateral wall 8 of the pot 2. Said skirt 10 extends along the longitudinal axis X, at least in a closed position of the receptacle, as in
To open and/or close the receptacle 1, as may be seen more clearly in
The first row of protrusions 14 of the pot 2 is located close to a free edge 9 of the lateral wall 8 of the pot 2 and the second row of protrusions 14′ of the pot 2 is located below. The second row of protrusions 16′ of the cover 4 is located close to a free lateral edge 11 of the lateral skirt 12 of the cover 4 and the first row of protrusions 16 of said cover 4 is located between said first row of protrusions 16′ of the cover 4 and the upper wall 10 of said cover 4.
The radial offset between the protrusions 14, 16 of the first row and those 14′, 16′ of the second row is configured to ensure that the protrusions of the cover 4 of one of the rows, in this case the protrusions 16′, do not abut against the protrusions of the pot 2 of the other row, in this case the protrusions 14, when the cover 4 is inserted onto the pot 2 in a movement along the longitudinal axis X of the receptacle.
The axial offset between the protrusions 14, 16 of the first row and those 14′, 16′ of the second row is configured so that the protrusions of one of the rows angularly complement those of the other row by providing a passage 18 for the protrusions of one of the rows of the cover 4, in this case the protrusions 16, between the two rows of the protrusions 14, 14′ of the pot 2 when the cover 4 is rotated relative to the pot 2 about the longitudinal axis X of the receptacle.
Said first and second protrusions 14, 16 and 14′, 16′ are configured to cooperate with each other respectively so as to obtain contact areas.
In other words, said first protrusions 14 of the pot 2 and said first protrusions 16 of the cover 4 are configured to engage respectively against each other to close the receptacle. Said second protrusions 14′ of the pot 2 and said second protrusions 16′ of the cover 4 are also configured to engage against each other to close the receptacle.
Said contact areas are distributed over the whole of said circumference, said contact areas extending angularly over at least 270° in the closed position of said receptacle. In other words, if the angular span of the areas in which said first protrusions 14 of the pot 2 are in contact with said first protrusions 16 of the cover 4 and that of the areas in which said second protrusions 14′ of the pot 2 and said second protrusions 16′ of the cover 4 are in contact are added together, in the closed position of the receptacle, the total angular span of these contact areas reaches and/or exceeds 270°.
With such an angular span, made possible by the distribution of the protrusions in at least two rows, the contact area in accordance with the invention provides an improved sealing without having to resort, or only partially, to screwing.
As may be seen more clearly in views 3a to 3c, preferably said first and second protrusions 14, 16, 14′, 16′ are configured to engage respectively against each other to close the receptacle in a movement referred to as bayonet movement comprising an axial translation of said cover 4, according to the arrow marked 20, relative to said pot 2 followed by a rotation about said longitudinal axis X, according to the arrow marked 22. In other words, with the two rows of protrusions, the receptacle conforming to the invention comprises a double bayonet closure system.
In view 3a, the cover 4 is in a high position relative to the pot 2 and its protrusions 16, 16′ are all above the protrusions 14, 14′ of the pot 2. In view 3b, the cover 4 is in a low position relative to the pot 2 and its first-row protrusions 16 are below the axial level of the first-row protrusions 14 of the pot 2, while the second-row protrusions 16′ of the cover 2 are below the axial level of the second-row protrusions 14 of the pot 2. To achieve this, the protrusions 16′ on the second row of the cover 4 are moved in front of the protrusions 14 on the first row of the pot, by the radial set back of the latter. Still in view 3b, the protrusions 14, 16 and 14′, 16′ of the same row are angularly offset from each other. More precisely, they are staggered or, in other words, in phase opposition. In view 3c, after rotation, they are now facing each other or, in other words, in phase.
Advantageously, the first protrusions 16 of the cover 4 and the first protrusions 14 of the pot 2 have approximately the same angular span. Cumulatively or alternatively, the second protrusions 16′ of the cover 4 and the second protrusions 14′ of the pot 2 have approximately the same angular span. Again cumulatively or alternatively, said first and second portions of the circumference are complementary to each other over substantially the whole of said circumference. In the illustrated embodiment, all these characteristics are combined and, in the closed position, an angular positioning of each of the first protrusions 14, 16 correspond to each other to form a contact area over their entire angular span. The same applies to the second protrusions 14′, 16′. In addition, the contact areas formed in this way follow one another in angular succession over almost the entire circumference of the receptacle, with the axial offset between the first and second rows close at hand.
More specifically, the first protrusions 14 of the pot 2 are four in number, the second protrusions 14′ of the pot 2 are four in number, the first protrusions 16 of the cover 4 are four in number and the second protrusions of the cover 4 are four in number, said first and second protrusions 14, 14′, 16, 16′ of the pot 2 and of the cover 4 having an angular span of approximately 45°. This is just one example allowing to have a total amplitude of contact areas of 360° and another number n of protrusions is possible, the angular amplitude of the protrusions then being 360°/n. Alternatively, and not illustrated, the first and/or the second protrusions 14, 14′ of the pot 2 or the first and/or second protrusions 16, 16′ of the cover 4 are formed by pins which make a tangential contact with the corresponding protrusions.
Advantageously, a height of said protrusions, more particularly of said second protrusions 16′ of the cover 2, is substantially identical to the axial offset between said first and second protrusions 14, 16, 14′, 16′. The aforementioned second protrusions 16′ of the cover 2 thus at least partially obstruct the aforementioned passage 18, even when the receptacle is in the closed position.
Again advantageously, an angular span of said first and/or second protrusions 14, 16, 14′, 16′ is substantially identical to an angular span of said rotation about the longitudinal axis X. This allows to ensure that the protrusions of the cover 4 are opposite the protrusions of the pot 2 in the closed position.
By way of example, an angle of said rotation about the longitudinal axis X is between 30° and 60°, in particular approximately 45°. In the embodiment shown, each row comprises eight protrusions, giving a total angular amplitude of almost 360° when the angular span of the protrusions 14, 16, 14′, 16′ of the two rows is added together.
As illustrated in
To allow said bayonet movement, said articulation 24 and with it said articulation axis Y are movable in translation along said longitudinal axis X and in rotation about said longitudinal axis X, relative to the pot 2. To this end, said articulation 24 comprises a ring 26 that is movable in rotation on the pot 2 about said longitudinal axis X.
As illustrated in
Referring also to
Said ring 26 comprises at least one angular groove 34 projecting radially inwards from an annular portion of said ring 26. Said groove 34 has opposite angular ends 36, 38 and a possible recess 40, located here close to a first 36 of said angular ends. Said gorge 28 comprises counter-forms 42, 44 and a possible snap-in pin 46. Said counter-forms 42, 44 and said pin 46 project radially outwards from a bottom of said gorge 28. Said snap-in pin 46 is located close to a first 42 of said counter-forms.
Said first 30 of the angular abutments of the ring 26 in the gorge 28 is formed, for example, by the first 36 of the angular ends of the groove 34, said first 36 of the angular ends of the groove 34 being configured to come to bear against the first 42 of the counter-forms in the position in question. In the latter position, said pin 46 is advantageously snapped into the recess 40. In other words, said first abutment comprises a notch for snapping the ring 26 onto the pot 2.
The second 32 of the angular abutments for the ring 26 in the gorge 28 is formed, for example, by the second 38 of the angular ends of the groove 34, said second 38 of the angular ends of the groove 34 being configured to come to bear against the second 44 of the counter-forms. Said first and second counter-forms 42, 44 are spaced apart. Alternatively, they are angularly continuous with each other and form one and the same counter-form and the abutments 30, 32 are formed, on the ring 26 side, by the opposite angular ends of said same counter-form.
To move from the open position shown in

In the embodiment shown in
As may be seen in
Said first protrusions 14 of the pot 2 are located at the level of the first stage 50. Said second protrusions 14′ of the pot 2 are located at the level of said second stage 52. Said first and second protrusions 14, 14′ of the pot 2 have a substantially identical radial extension from a lateral flank of the pot so that said first protrusions 14 of the pot 2 have a distal edge 56 which is radially offset, set back, with respect to the lateral flank of the pot 2 at the level of said second stage 52 and therefore with respect to said second protrusions 14′ of the pot 2 (this may also be seen in
Said first protrusions 16 of the cover 4 have a greater radial extension than the second extensions 16′ of the cover 4. Such a radial extension, combined with the radial set back of the first extensions 14 of the pot 2, allows the second protrusions 16′ of the cover 4 to pass in front of the first protrusions 14 of the pot 2 during the translation of the cover 4 along the longitudinal axis X, as mentioned above, while allowing the first protrusions 16 of the cover 4 to engage with said first extensions 14 of the pot 2 during the rotation of the cover 4 about the longitudinal axis X, despite the radial set back of said first extensions 14 of the pot 2.
Advantageously, said first extensions 14, 16 of the pot 2 and of the cover 4 are formed in complementary patterns. The same applies to the second extensions 14′, 16′. Said complementary patterns have opposite faces in the form of ramps 60, 62, in particular substantially helical ramps. Said ramps 60, 62 are configured to engage one against the other, thanks to a profile of said ramps, during the angular stroke described by the cover 2 during its rotation about said longitudinal axis X, particularly at mid-stroke. In other words, according to this example, a first half of the angular stroke of the cover 4 is free, without the protrusions engaging against each other. During the second half of the stroke, the protrusions are engaged one against the other to reach the end-of-stroke position. These ramps have an inflection point. In other words, a slope of said ramps is steeper downstream of said inflection point than upstream, in the direction of rotation. Note that this is not possible with conventional screwing.
In the illustrated embodiment, this means that the rotation phase of the bayonet movement has a slight screwing component due to the inclination of the ramps 60, 62, during the second portion of the angular stroke of the cover about the longitudinal axis X. However, this component is smaller, even much smaller than the component resulting from the previous phase of translation of the cover 2 along said longitudinal axis X. This difference may be seen in
Said protrusions 16, 16′ of the cover 4 are interrupted by a radial slot 64. Said radial slot 64 is angularly located, for example, at approximately mid-stroke. On the cover 4 side, said slot 64 advantageously forms the inflection point mentioned above.
As illustrated in
Said first and second protrusions 16, 16′ of said cover 4 originate from said cap 72. Said hinge 48 also comes from said cap 72.
The seal 70 comprises, for example, a disc 74 made of compressible material and a rigid support 76. Said disc 74 is connected to said support 76. Said support 76 is free to rotate in said cap 72 about said longitudinal axis X, at least during said bayonet movement. Said support 76 is, for example, snapped onto said cap 72, in particular into a gorge 78 in said cap 72. Said pot 2 comprises a case 80 defining a housing 82 and the receptacle 1 comprises a removable capsule 84, located in said housing 82. Said capsule 84 is configured to accommodate said product. Said capsule 84 has a lip 86 (visible in
Referring again to
Alternatively or cumulatively, the cover 4 is in axial abutment against the ring 26 and/or the ring 26 is in axial abutment against the pot 2, in the closed position. These characteristics help to give the receptacle a uniform appearance when closed.
Alternatively, the receptacle is configured to have a longitudinal clearance 100, visible in
According to the embodiments 10 and 11, said receptacle is preferably identical to the above except for the hinge 48. In fact, the latter is linked both to said ring 26, in particular is in one piece with said ring, and to said cover 4, in particular is in one piece with said cover. Said hinge 48 is also elastically deformable. To do this, it comprises first and second flaps 482, 484 connected by a thinning of material 486 forming a fold line of said hinge 48. The first flap 482 is connected to the cover 4 and/or the second flap 484 is connected to the ring 26. Said folding line 486 is oriented substantially tangentially to said pot 2 and/or to said cover 4. In other words, said hinge 48 is, for example, a film hinge.
Said hinge 48 is configured so that, in the open position, as illustrated in
Said hinge 48 is configured so that, in the closed position, as illustrated in
In accordance with this embodiment, it is understood that the assembly formed by the cover 4, the ring 26 and the hinge 48 is preferably made in one-part. The result is a more functional 48 hinge that opens and closes in a simpler position. This also allows to arrange a thinner hinge 48, making the receptacle more aesthetically pleasing. The industrial integration of said articulation 24 is also simplified by the reduction in the number of parts and their relative adjustment in position.
It should also be noted that, particularly in the absence of a ring, the receptacle is advantageously equipped with an end-of-stroke catch, in particular formed by corresponding shapes on the pot 2 and/or the cover 4, one of the shapes being located, for example, on a free edge of the pot 2 to cooperate with a shape on the bottom of the cover 4, or alternatively, on an upper face of the first and second protrusions 14, 14′ of the pot 2, or at least one of them, to cooperate with the corresponding slot or slots 64 of the first and second protrusions 16, 16′ of the cover 4.
