Description

The present invention relates to an applicator cap for applying a cosmetic composition, and to a cosmetic device for packaging and applying such a cosmetic composition to be applied.

In the cosmetics field, it is known to use cosmetic devices for applying cosmetic compositions to different parts of the body, such as for example the nails, the eyelashes, the lips, the hair, or even the skin; such cosmetic compositions which can for example be in a liquid, fluid, gelled, powdery, viscous, creamy, pasty, emulsified form, with or without solid particles in suspension, and such cosmetic compositions which can for example be make-up compositions (nail nail polish, foundation, lip gloss, lipstick, eyeliner, mascara or any other cosmetic composition intended for the embellishment of a part of the body), or body or dermatological care or hygiene compositions ( care cream, lip balm, anti-wrinkle cream, concealer cream, dermatological cream...).

Conventionally, and as known for example from the document WO 2018/009590 , such a cosmetic device comprises a container containing the cosmetic composition to be applied and provided with a threaded neck on which a gripping sleeve is mounted by screwing, where the gripping sleeve supports an application rod which, on the one hand, is fixedly mounted in the gripping sleeve and which, on the other hand, is provided with an application head plunging inside the container into the cosmetic composition.

However, when the gripping sleeve is unscrewed, the latter, by abutting against the top of the neck of the container, prevents the applicator head from reaching the bottom of the container, thus contributing to a mess of cosmetic composition.

To solve this problem, many solutions are known with a telescopic application rod, in other words an application rod which can slide and be deployed so that its application head can reach the bottom of the container with the gripping sleeve. open.

A first solution is known from the document US 6,164,857 wherein an applicator cap comprises a gripping sleeve provided with a threaded sleeve for mounting by screwing on a threaded neck of a container, and an insert mounted over the threaded sleeve. This applicator plug further comprises an applicator rod which passes through both the threaded sleeve and the insert to present an upper end integral with a thrust member and a lower end supporting an applicator head. A compression spring is inserted between the insert and the thrust member. Thus, by pushing on the thrust member, the applicator rod can slide from a retracted position to an extended position so that the applicator head can reach the bottom of the container.

However, this first solution has a drawback which is that, once the gripping sleeve is completely screwed onto the neck of the container, it is possible to inadvertently push in the thrust member and thus crush the applicator head against the bottom. of the container. To guard against this first drawback, a cover is provided which is snapped onto the top of the gripping sleeve and which caps the thrust member. However, under strong pressure, for example inside a bag, it remains possible to push this cover and consequently to push the push member, not to mention that the use of such a cover complicates the The use of the applicator cap creates a risk of loss of the lid and induces additional costs for the lid and for mounting the lid on an industrial assembly line.

A second solution is known from the documents US 6,872,020 And US 5,096,320 wherein an applicator cap comprises a gripping sleeve provided with a lower thread for mounting by screwing on a threaded neck of a container, and an internal shoulder above the lower thread. This applicator cap further comprises an applicator rod which passes through both the lower internal thread and the internal shoulder to present an upper end integral with a thrust member and a lower end supporting an applicator head. A compression spring is inserted between the internal shoulder and the thrust member. Thus, by pushing on the thrust member, the applicator rod can slide from a retracted position to an extended position so that the applicator head can reach the bottom of the container.

However, this second solution has the same drawback as the first solution described above, which is that, once the gripping sleeve is completely screwed onto the neck of the container, it is possible to inadvertently push in the pushing member and thus crushing the applicator head against the bottom of the container.

The object of the present invention is in particular to solve the aforementioned drawbacks, by proposing an applicator cap which makes it possible to block the application rod when the gripping sleeve is mounted and closed on the container, thus avoiding inadvertent crushing of the head of application against the bottom of the container.

Another object of the invention is to propose an applicator cap which is adapted to the industrial assembly lines in force.

Another object of the invention is to provide an applicator cap which allows manufacture and assembly at a reduced cost.

Another object of the invention is to provide an applicator cap which is suitable for standard applicator rods and applicator heads.

où ce bouchon applicateur est remarquable en ce que :

• l'organe de poussée comprend une tige inférieure solidaire de la tête supérieure et qui s'étend à l'intérieur de l'orifice central du manchon de préhension en traversant l'épaulement interne dans la position rétractée, de sorte que ladite tige inférieure présente une terminaison libre disposée en-dessous de l'épaulement interne tandis que la tête supérieure est disposée au-dessus de l'épaulement interne ; et
• l'extrémité supérieure du corps de tige supporte un embout d'accouplement qui, d'une part, est élargi comparativement au corps de tige pour être apte à venir en appui sur ledit col du récipient et, d'autre part, est accouplé en force, par emboîtement, avec la terminaison libre de la tige inférieure de l'organe de poussée.

To this end, it offers an applicator cap comprising:

• a gripping sleeve capable of being removably mounted on a neck of a container intended to contain a cosmetic composition to be applied,
• an application rod comprising a rod body adapted to pass through the neck of the container and to engage at least partially inside the container, where this rod body is provided with two opposite ends including an upper end and a lower end protruding from the gripping sleeve and supporting an application head, where the application rod is slidably movable inside a central orifice provided in the gripping sleeve, between a retracted position and an extended position;
• a thrust member coupled to the applicator rod to move the applicator rod from its retracted position to its deployed position under the effect of a thrust exerted on an upper head of the thrust member; And
• an elastic return member urging the applicator rod towards its retracted position, where the elastic return member is interposed between the upper head of the thrust member and an internal shoulder provided in the central orifice of the sleeve of gripping;

where this applicator cap is remarkable in that:

• the thrust member comprises a lower rod integral with the upper head and which extends inside the central orifice of the sleeve of gripping by crossing the internal shoulder in the retracted position, so that said lower rod has a free ending arranged below the internal shoulder while the upper head is arranged above the internal shoulder; And
• the upper end of the rod body supports a coupling piece which, on the one hand, is widened compared to the rod body to be capable of coming to rest on said neck of the container and, on the other hand, is coupled in force, by interlocking, with the free end of the lower rod of the thrust member.

Thus, with such a design, when the gripping sleeve is mounted and closed on the container, the coupling tip of the applicator rod will find itself wedged between, on the one hand, the free end of the lower rod of the pushing member and, on the other hand, the neck of the container, thus helping to block the applicator rod in its retracted position and therefore which cannot be pressed down inadvertently.

Furthermore, on an industrial assembly line, it will suffice to place the application rod on the container, with the coupling endpiece which bears against the periphery of the neck of the container, then to place the assembly handle sleeve/thrust member/elastic return member above the container and therefore the applicator rod, and finally to lower this assembly to mount and close the handle sleeve on the neck of the container (in particular by screwing) and, concomitantly, fitting the coupling end piece of the applicator rod with the free end of the lower rod of the pusher member.

Thus, the invention makes it possible to respect the method conventionally implemented on industrial assembly lines, where the application rod rests beforehand on the container before the gripping sleeve is mounted (and screwed) on the neck of the container while concomitantly coupling the application rod to the gripping sleeve.

Furthermore, it is understood that, within the meaning of the invention, the application rod is mobile in sliding inside the central orifice of the gripping sleeve excluded mobility by screwing of the application rod in the grip sleeve; in other words, within the meaning of the invention, the applicator rod is not moved according to a screwing movement inside this central orifice, but it is moved according to a sliding (or translation) movement.

In addition, the coupling tip is widened compared to the rod body means that the coupling tip has at least one transverse dimension (dimension taken in a plane orthogonal to the longitudinal axis of the application rod) to the transverse dimension of the rod body.

According to one characteristic, the central orifice of the gripping sleeve has a removable mounting portion extending below the internal shoulder and shaped for removable mounting on the neck of the container, so that, in the retracted position of the applicator rod, the free end of the lower rod of the pusher member is surrounded at least partially by said removable mounting portion or at least partially by a smooth intermediate portion interposed between said removable mounting portion and said internal shoulder .

According to another characteristic, the removable mounting portion is either a removable mounting portion by screwing provided with an internal thread, or a removable mounting portion with bayonet, or a removable mounting portion by snap-fastening.

In a particular embodiment, the central orifice of the gripping sleeve has a lower portion extending below the removable assembly portion and opening onto the underside of the gripping sleeve, where this lower portion is smooth.

Advantageously, the internal shoulder is in the form of an annular projection inside the central orifice of the gripping sleeve, such an annular projection defining two opposite annular faces including an upper annular face on which the elastic return member and a lower annular face, and the free end of the lower rod of the thrust member is provided with an outer collar projecting peripherally, where such an outer collar is arranged below the internal shoulder and bears against the lower annular face of this annular projection in the retracted position of the applicator rod.

Thus, this external collar, which has previously been forced through the annular projection (in other words through the internal shoulder), will make it possible to block the gripping sleeve in the direction of an ascent (in other words in the direction an exit upwards from the gripping sleeve), because this outer collar bears against the lower annular face of the annular projection.

In a particular embodiment, the free end of the lower rod of the thrust member is tubular, and the coupling end piece of the applicator rod is force-coupled, by fitting, inside the free termination.

According to a variant, the coupling end piece of the applicator rod is tubular, and this coupling end piece is force-coupled, by interlocking, around the free end.

According to one possibility of the invention, the coupling end piece of the applicator rod has an upper shoulder forming a stop against the free end.

According to another possibility of the invention, the upper head of the thrust member is slidably guided inside an upper portion of the central orifice of the gripping sleeve, this upper portion extending above of the internal shoulder and opening onto the top of the gripping sleeve, where this upper head and this upper portion of the central orifice are of complementary and non-cylindrical shapes so that this upper head is mobile only by sliding inside from the upper portion of the central hole.

Thus, the applicator rod is movable only in sliding, without the possibility of rotation about its own axis, to mechanically optimize its sliding movement.

According to another characteristic of the invention, the elastic return member is a helical compression spring.

According to a variant, the coupling end piece of the applicator rod is integral with the body of the rod.

According to another variant, the coupling end piece of the applicator rod is attached to and secured to the rod body.

According to a variant, the internal shoulder of the central orifice of the gripping sleeve is integral with the gripping sleeve.

According to another variant, the internal shoulder of the central orifice of the gripping sleeve is in the form of an attached insert and fixed inside the central orifice of the gripping sleeve.

According to one possibility, the lower rod of the thrust member is integral with the upper head of the thrust member, so that this lower rod and this upper head are formed in one piece.

Alternatively, the lower rod of the thrust member is secured to the upper head of the thrust member by assembly, so that this lower rod and this upper head are separate elements assembled together, for example by interlocking, by screwing, gluing or welding.

The invention also relates to a cosmetic device for packaging and applying a cosmetic composition to be applied, such a cosmetic device comprising:

• a container intended to contain the said cosmetic composition to be applied, and having a bottom and a neck internally delimiting an inlet orifice; And
• an applicator cap according to the invention;

• wherein the gripping sleeve of the applicator cap is adapted to be removably mounted on the neck of the container and is configurable between:

  • an open position in which the gripping sleeve does not cooperate with said neck to allow detachment vis-à-vis the neck;
• and in which the coupling piece of the applicator rod comes to rest on said neck when the gripping sleeve is in the closed position, thereby locking the applicator rod in the retracted position and thus closing the orifice of container entrance.

Advantageously, when the gripping sleeve passes from its closed position to its open position, the coupling tip of the application rod takes off from the neck of the container and thus the application rod is free to be moved towards its position. deployed, in the direction of the bottom of the container, under the effect of a thrust exerted on the upper head of the thrust member.

The present invention also relates to the characteristic according to which the gripping sleeve of the applicator cap is adapted to be mounted by screwing on the neck of the container.

According to a variant, the gripping sleeve of the applicator cap is adapted to be mounted by bayonet on the neck of the container.

• un manchon de préhension 2 ;
• une tige d'application 3 s'étendant selon un axe longitudinal 30 ;
• un organe de poussée 4 ; et
• un organe de rappel élastique 5.

With reference to figures 1 to 6 , to figures 11 and 12 for a first variant as well as to figures 13 and 14 for a second variant, an applicator cap 1 according to the invention comprises four elements which are:

• a gripping sleeve 2;
• an application rod 3 extending along a longitudinal axis 30;
• a thrust member 4; And
• an elastic return member 5.

The following description applies both to the embodiment of the figures 1 to 6 as well as variants of figures 11, 12 And 13, 14 , except for the passages which explain the specific features of the variants.

With reference to figures 7 to 10 , such an applicator cap 1 is intended to be associated with a container 6 to together form a cosmetic device 10 for packaging and applying a cosmetic composition to be applied, such as, for example and without limitation, a nail polish composition. nails.

Such a container 6 is for example made entirely of glass or plastic material, and it comprises a hollow body 60 delimiting an interior volume 61 provided to contain the cosmetic composition and provided with a bottom 62.

The container 6 is also provided with a neck 63, on top of the hollow body 60, where this neck 63 is provided with an external thread 64 and internally delimits an inlet orifice 65 allowing access to the interior volume 61.

• permettre de fermer de manière amovible le récipient 6 ;
• former une partie de préhension du bouchon applicateur 1, autrement dit permettre de saisir manuellement le bouchon applicateur 1 ;
• former une partie de support de la tige d'application 3 de sorte que cette tige d'application 3 s'étende au moins partiellement à l'intérieur du récipient 6 lorsque le manchon de préhension 2 est en position fermée ; et
• guider la tige d'application 3 à l'intérieur du manchon de préhension 2, ce guidage étant assuré en coopération avec l'organe de poussée 4.

Grip sleeve 2 has four features which are as follows:

• allow to removably close the container 6;
• forming a gripping part of the applicator cap 1, in other words allowing manual gripping of the applicator cap 1;
• forming a support part of the application rod 3 so that this application rod 3 extends at least partially inside the container 6 when the gripping sleeve 2 is in the closed position; And
• guiding the applicator rod 3 inside the gripping sleeve 2, this guiding being ensured in cooperation with the thrust member 4.

This gripping sleeve 2 is formed of a hollow body made in particular of plastic or other material, and which has a peripheral wall 20 connecting an upper wall 21 (on the top of the gripping sleeve 2) and a lower wall 22 (on the below the grip sleeve 2).

This gripping sleeve 2 has a central orifice 23 which passes through it over its entire height and therefore which opens both into the lower wall 22, in other words on the underside of the gripping sleeve 2, and into the upper wall 21, in other words on top of grip sleeve 2.

• une portion supérieure 24 débouchant dans la paroi supérieure 21 et qui est relativement large comparativement au reste de l'orifice central 23, où cette portion supérieure 24 est non cylindrique, en étant par exemple de section oblongue telle qu'une section ovoïdale, où cette portion supérieure 24 présente un fond 240 ;
• une portion intermédiaire 25 sous la forme d'un alésage cylindrique et lisse, débouchant dans le fond 240 de la portion supérieure 24, et centré sur l'axe longitudinal 30 de la tige d'application 3 ;
• un épaulement interne 26 qui se présente sous la forme d'une saillie annulaire à l'intérieur de l'orifice central 23 définissant deux faces annulaires opposées incluant une face annulaire supérieure (tournée du côté de la paroi supérieure 21) et une face annulaire inférieure (tournée du côté de la paroi inférieure 22) ;
• une portion de montage amovible 27 s'étendant en-dessous de l'épaulement interne 26, sous la forme d'un alésage taraudé conformé pour un montage par vissage sur le col 63 du récipient 6, et plus spécifiquement sur son filetage externe 64 ; et
• une portion inférieure 28 s'étendant en-dessous de la portion de montage amovible 27, sous la forme d'un alésage cylindrique et lisse qui est débouchant dans la paroi inférieure 22 et qui est centré sur l'axe longitudinal 30 de la tige d'application 3.

This central orifice 23 has successively, starting from the upper wall 21 (from above) towards the lower wall 22 (from below):

• an upper portion 24 opening into the upper wall 21 and which is relatively wide compared to the rest of the central orifice 23, where this upper portion 24 is non-cylindrical, being for example of oblong section such as an ovoid section, where this upper portion 24 has a bottom 240;
• an intermediate portion 25 in the form of a smooth cylindrical bore, opening into the bottom 240 of the upper portion 24, and centered on the longitudinal axis 30 of the applicator rod 3;
• an internal shoulder 26 which is in the form of an annular projection inside the central orifice 23 defining two opposite annular faces including an upper annular face (facing the side of the upper wall 21) and a lower annular face (turned towards the side of the lower wall 22);
• a removable mounting portion 27 extending below the internal shoulder 26, in the form of a threaded bore shaped for mounting by screwing on the neck 63 of the container 6, and more specifically on its external thread 64; And
• a lower portion 28 extending below the removable mounting portion 27, in the form of a cylindrical and smooth bore which opens into the lower wall 22 and which is centered on the longitudinal axis 30 of the rod of app 3.

In the first embodiment of the figures 11 and 12 , the central orifice 23 has another intermediate portion 29 in the form of a cylindrical and smooth bore, interposed between the internal shoulder 26 and the removable assembly portion 27, and thus arranged in the continuity of the intermediate portion 25 with the internal shoulder 26 extending between the intermediate portion 25 and the other intermediate portion 29.

Thus, the gripping sleeve 2 is adapted to be mounted by screwing on the neck 63 of the container 6, more precisely by screwing the external thread 64 of the neck 63 into the tapping of the removable mounting portion 27 of the central orifice 23.

In a variant not shown, the removable mounting portion 27 is a removable bayonet mounting portion, for bayonet mounting of the gripping sleeve 2 on the neck 63 of the container 6.

In another variant not shown, the removable mounting portion 27 is a removable snap-fit mounting portion, for snap-fit mounting of the gripping sleeve 2 on the neck 63 of the container 6.

• une position fermée, illustrée sur la figure 8, dans laquelle le manchon de préhension 2 coopère par vissage avec le col 63, autrement dit le manchon de préhension 2 est vissé sur le col 63, procurant ainsi un attachement du manchon de préhension 2 et donc du bouchon applicateur 1 sur le col 63 ; et
• une position ouverte, illustrée sur les figures 9 et 10, dans laquelle le manchon de préhension 2 ne coopère pas avec le col 63, autrement dit le manchon de préhension 2 est dévissé du col 63, pour autoriser un détachement du manchon de préhension 2 et donc du bouchon applicateur 1 vis-à-vis du col 63.

Thus, the gripping sleeve 2 is configurable between:

• a closed position, illustrated on the figure 8 , in which the gripping sleeve 2 cooperates by screwing with the neck 63, in other words the sleeve of grip 2 is screwed onto the neck 63, thus providing an attachment of the gripping sleeve 2 and therefore of the applicator cap 1 on the neck 63; And
• an open position, illustrated on the figures 9 and 10 , in which the gripping sleeve 2 does not cooperate with the neck 63, in other words the gripping sleeve 2 is unscrewed from the neck 63, to allow a detachment of the gripping sleeve 2 and therefore of the applicator cap 1 vis-à-vis the collar 63.

In the closed position, the lower wall 22 of the gripping sleeve 2 can marry, either in contact or with a predefined clearance, the top of the hollow body 60 of the container 6.

The application rod 3 comprises an at least partially tubular rod body 31, centered on the longitudinal axis 30, which is sized to pass through the inlet orifice 65 and therefore to pass through the neck 63 of the container 6 and engage at least partially inside the interior volume 61 of the container 6.

This applicator rod 3 extends partially and with a clearance inside the central orifice 23 of the gripping sleeve 2, and more precisely inside the removable mounting portion 27 and the lower portion 28 , or even inside the intermediate portion 29 when present. In other words, this application rod 3 is not guided in sliding, in other words it is not in sliding connection in the central orifice 23 of the gripping sleeve 2.

• une extrémité supérieure 32 supportant un embout d'accouplement 34 ; et
• une extrémité inférieure 33 dépassant du manchon de préhension 2 et supportant une tête d'application 35.

This rod body 31 is provided with two opposite ends 32, 33 including:

• an upper end 32 supporting a coupling piece 34; And
• a lower end 33 projecting from the gripping sleeve 2 and supporting an application head 35.

The application head 35 is fixed inside the rod body 31 at its lower end 33. This application head 35 is, for example and without limitation, of the brush, brush, head made of absorbent material, thermoplastic head or foam head.

The coupling tip 34 is widened compared to the rod body 31, in other words the transverse dimension of the coupling tip 34 (taken in a plane orthogonal to the longitudinal axis 30) is greater than the transverse dimension of the body of stem 31.

The coupling end piece 34 thus has a lower face 340, facing the side of the application head 35, which projects peripherally around the upper end 32 of the rod body 31.

This coupling piece 34 is made in one piece with the rod body 31, in particular in a plastic material. The coupling piece 34 also has an upper shoulder 341 defining an upper face 342, opposite the lower face 340.

The thrust member 4 comprises an upper head 40 mounted to slide inside the upper portion 24 of the central orifice 23 of the gripping sleeve 2.

This upper head 40 is of complementary shape, therefore not cylindrical, to that of the upper portion 24 of the central orifice 23, so that this upper head 40 is movable only in sliding inside this upper portion 24 of the central orifice 23. In other words, the upper head 40 is in sliding connection with the upper portion 24 of the central orifice 23, thus guiding the sliding of the thrust member 4 / applicator rod 3 assembly.

• une face supérieure 41 formant une face sur laquelle une poussée peut être exercée ; et
• une face inférieure 42 tournée du côté de la tige d'application 3.

This upper head 40 has two opposite faces including:

• an upper face 41 forming a face on which a thrust can be exerted; And
• a lower face 42 facing the side of the application rod 3.

The thrust member 4 comprises a lower rod 43 integral with the upper head 40, projecting from its lower face 42. This lower rod 43 is centered on the longitudinal axis 30 of the application rod 3.

In the embodiment illustrated in the figures 1 to 6 , and also in the first variant of figures 11 and 12 , the lower rod 43 is integral with the upper head 40 and thus the thrust member 4 is a single piece. Moreover, in this embodiment of the figures 1 to 6 and in the first variant of figures 11 and 12 , the lower rod 43 is in the form of a tubular shaft.

In the second variant illustrated on the figures 13 and 14 , the lower rod 43 is integral with the upper head 40 by interlocking and thus the thrust member 4 is formed by an assembly of the upper head 40 and the lower rod 43. To do this, the upper head 40 has on its underside 42 a fitting hole 420 inside which is mounted an upper termination 430 of the lower rod 43. Alternatively, this upper end 430 of lower rod 43 is secured by screwing into hole 420.

This lower rod 43 has a hollow free end 44, inside which is force-coupled, by interlocking, the coupling end piece 34 of the applicator rod 3, thus securing the thrust member 4 and the application rod 3.

The coupling piece 34 is mounted inside the free termination 44 until the upper face 342 of the upper shoulder 341 abuts against the free termination 44; this upper shoulder thus forming an abutment against the free termination 44.

Thus, the thrust member 4 is coupled to the applicator rod 3 to move the applicator rod 3 from a retracted position (visible on the figures 1, 3 , 5 , 8 , 9 And 11 ) to a deployed position (visible on the figure 2 , 6 , 10 And 12 ) under the effect of a thrust exerted on the upper face 41 of the upper head 40 of the thrust member 4.

The applicator rod 3 is thus slidably movable inside the central orifice 23 provided in the gripping sleeve 2, between the retracted position and the deployed position. To pass from the retracted position to the deployed position, the upper head 40 is pushed downwards, which causes the applicator rod 3 to slide downwards so that the applicator head 35 can approach, or even reach, the bottom 62 of container 6.

The lower rod 43 of the thrust member 4 extends inside the central orifice 23 of the gripping sleeve 2 and crosses the internal shoulder 26 in the retracted position, so that its free end 44 is disposed below the internal shoulder 26 while the upper head 40 is obviously placed above the internal shoulder 26.

Thus, in the retracted position of the applicator rod 3, the free end 44 of the lower rod of the pusher member is surrounded at least partially by the removable assembly portion 27, as visible on the figure 5 .

In the first variant of the figure 11 , in the retracted position of the application rod 3, the free end 44 of the lower rod 43 of the thrust member 4 is surrounded at least partially by the intermediate portion 29 interposed between the internal shoulder 26 and the portion of removable mount 27.

Furthermore, the free end 44 of the lower rod 43 is provided, on its outer periphery, with an outer collar 45 projecting peripherally.

In the retracted position of the applicator rod 3, this external collar 45 is arranged below the internal shoulder 26 and bears against the lower annular face of this internal shoulder 26 (formed as a reminder of an annular projection ). This outer collar 45 thus prevents the thrust member 4 from coming out of the top out of the gripping sleeve 2.

The thrust member 4 is assembled in the central hole 23 of the gripping sleeve 2 from above (or above) and is pushed inside this central hole 23 until the outer collar 45 comes against the upper annular face of the internal shoulder 26 then, by forcing downwards on the thrust member 4, the external collar 45 passes below the internal shoulder 26.

The elastic return member 5 is inserted between the upper head 40 of the thrust member 4 and the internal shoulder 26 provided in the central orifice 23 of the gripping sleeve 2.

• sur le haut, sur un épaulement supérieur 46 ménagé en partie haute de la tige inférieure 43 ; et
• sur le bas, sur la face annulaire supérieure de l'épaulement interne 26.

More specifically, this elastic return member 5, which is in the form of a helical compression spring, is supported:

• on the top, on an upper shoulder 46 formed in the upper part of the lower rod 43; And
• on the bottom, on the upper annular face of the internal shoulder 26.

This elastic return member 5 urges the applicator rod 3 upwards, towards its retracted position, against a downward thrust on the upper head 40 of the thrust member 4, so that the applicator rod 3 naturally returns to its retracted position in the absence of a downward thrust on the thrust member 4.

The elastic return member 5 also urges the outer collar 45 against the lower annular face of the inner shoulder 26.

With reference to the figure 8 , when the gripping sleeve 2 is in the closed position, the coupling end piece 34 of the applicator rod 3 bears against the neck 63 of the container 6, and more precisely the lower face 340 of this coupling end piece 34 bears against the periphery of the neck 63. Thus, when the gripping sleeve 2 is in the closed position, the coupling end piece 34 of the applicator rod 3 blocks the applicator rod 3 in its retracted position and closes the inlet 65 of the neck 63 of the container 6.

The underside 340 of this coupling piece 34 is wide enough to bear against the periphery of the neck 63 and close its inlet 65.

With reference to figures 9 and 10 , when the gripping sleeve 2 moves from its closed position to its open position, the coupling end piece 34 of the applicator rod 3 lifts off from the neck 63 of the container 6 and thus the applicator rod 3 is no longer blocked and is now free to be moved towards its deployed position, in the direction of the bottom 62 of the container 6, under the effect of a thrust exerted on the upper head 40 of the thrust member 4.

Thus, when the gripping sleeve 2 is closed by screwing onto the neck 63 of the container 6, the coupling end piece 34 of the applicator rod 3 will find itself wedged between, on the one hand, the free end 44 of the lower rod 43 of the pushing member 4 and, on the other hand, the neck 63 of the container 6, thus contributing to blocking the applicator rod 3 in its retracted position and thus preventing the latter from being pressed inadvertently against the bottom 62 of the container 6.

• la tige d'application 3 est placée sur le récipient 6, avec l'embout d'accouplement 34 qui vient en appui sur le pourtour du col 63 du récipient 6 ;
• l'organe de rappel élastique 5 est monté autour de la tige inférieure 43 de l'organe de poussée 4 ;
• l'ensemble organe de poussée 4 / organe de rappel élastique 5 est inséré par le haut à l'intérieur de l'orifice central 23 du manchon de préhension 2 jusqu'à ce que le collet externe 45 passe en force par-dessous l'épaulement interne 26 et l'organe de rappel élastique 5 vienne repose contre l'épaulement interne 26 ;
• l'ensemble manchon de préhension 2 / organe de poussée 4 / organe de rappel élastique 5 est positionné au-dessus du récipient 6 supportant la tige d'application 3, dans l'alignement de l'axe longitudinal 30 ; et
• l'ensemble manchon de préhension 2 / organe de poussée 4 / organe de rappel élastique 5 est descendu puis le manchon de préhension 2 est vissé sur le col 63 du récipient 6 jusqu'à ce que l'embout d'accouplement 34 de la tige d'application 3 vienne buter contre la terminaison libre 44 de la tige inférieure 43 de l'organe de poussée 4 ;
• le vissage du manchon de préhension 2 sur le col 63 est poursuivi, forçant ainsi l'embout d'accouplement 34 à l'intérieur de la terminaison libre 44, de sorte que l'embout d'accouplement 34 est monté en force à l'intérieur de la terminaison libre 44 jusqu'à ce que la face supérieure 342 de l'épaulement supérieur 341 vienne buter contre la terminaison libre 44.

On an industrial assembly line, the assembly will be carried out as follows:

• the applicator rod 3 is placed on the container 6, with the coupling piece 34 which bears against the periphery of the neck 63 of the container 6;
• the elastic return member 5 is mounted around the lower rod 43 of the thrust member 4;
• the thrust member 4/elastic return member 5 assembly is inserted from above inside the central orifice 23 of the gripping sleeve 2 until the outer collar 45 passes by force underneath the internal shoulder 26 and the elastic return member 5 comes to rest against the internal shoulder 26;
• the gripping sleeve 2 / thrust member 4 / elastic return member 5 assembly is positioned above the container 6 supporting the applicator rod 3, in alignment with the longitudinal axis 30; And
• the grip sleeve 2 / thrust member 4 / elastic return member 5 assembly is lowered then the grip sleeve 2 is screwed onto the neck 63 of the container 6 until the coupling end piece 34 of the stem application 3 abuts against the free end 44 of the lower rod 43 of the thrust member 4;
• the screwing of the gripping sleeve 2 on the neck 63 is continued, thus forcing the coupling end piece 34 inside the free end 44, so that the coupling end piece 34 is force-fitted at the inside of the free termination 44 until the upper face 342 of the upper shoulder 341 abuts against the free termination 44.
