    le capuchon de fermeture (38), dans son état obturant de manière étanche la partie en pointe (14), repose de façon étanche, à l'aide d'un élément d'étanchéité à ressort (52) prévu au niveau de sa partie inférieure (50), sur une face d'extrémité annulaire (54) de la partie en pointe (14).
  14. Applicateur selon l'une quelconque des revendications précédentes,
    caractérisé en ce que
    l'organe d'application (18) est formé par un élément brosse.

    caractérisé en ce que
    un élément de dosage (84) est prévu sur la tige de piston (18) qui, au moins dans la zone d'une chambre d'alimentation (90) de l'applicateur, présente une configuration de surface ayant une résistance accrue à l'écoulement du fluide à appliquer environnant, dans lequel le dosage du fluide à appliquer survient via un déplacement vers l'avant de l'élément de dosage (84) pour transporter une quantité déterminée du fluide à appliquer jusque dans une chambre de dosage (92) prévue dans une partie de pointe (14) de l'applicateur (10), et dans lequel, pendant le déplacement de retour de l'élément de dosage (84), d'une part une compensation de pression est possible, et d'autre part le fluide à appliquer va être retenu dans la chambre de dosage (92) par des forces d'adhérence et/ou capillaires.
  16. Applicateur selon la revendication 15,
    caractérisé en ce que
    l'organe d'application (18) est conçu de telle sorte qu'il a pour résultat une adhérence élevée du fluide à appliquer au moins sur sa surface supérieure.
  17. Applicateur selon la revendication 15,
    caractérisé en ce que
    la surface supérieure de l'élément de dosage (4) est conçue de telle sorte qu'une bonne adhérence du fluide à appliquer a lieu, qui est suffisante, en conjonction avec la force de gravité, pour transporter le fluide à appliquer jusqu'à la chambre de dosage (92), dans lequel des forces d'adhérence supplémentaires produites dans la chambre de dosage (92) et la force de la gravité agissant dans la même direction amènent au moins une partie du fluide à appliquer à rester dans la chambre de dosage et à mouiller l'organe d'application (18).
  18. Applicateur selon la revendication 15,
    caractérisé en ce que
    le diamètre de la chambre de dosage (92) est inférieur ou égal à celui de la chambre d'alimentation (90).

  20. Applicateur selon la revendication 15,
    caractérisé en ce que
    dans l'état étendu de l'élément de dosage (84) relié à la tige de piston (18), celui-ci est conçu avec l'organe d'application (18) de telle sorte qu'une étanchéité de l'espace de stockage du contenant de stockage (12) de l'applicateur (10) est formée, aucun fluide ne pouvant continuer de circuler.
  21. Applicateur selon la revendication 15,
    caractérisé en ce que
    l'élément de dosage (84), dans l'état rétracté de repos de l'applicateur (10), forme également un joint d'étanchéité, de telle sorte qu'aucun fluide à appliquer ne passe vers l'avant au-delà de l'embout d'application de l'organe d'application (18) vers l'extérieur.
  22. Applicateur selon la revendication 15,
    caractérisé en ce que
    le joint d'étanchéité, dans l'état de d'application active de l'applicateur (10), est réalisé via une section transversale légèrement plus petite que la section transversale de la chambre d'alimentation (90), qui génère une étanchéité sûre lors d'un déplacement défini de la tige de piston (20) jusque dans l'état étendu.
  23. Applicateur selon la revendication 22,
    caractérisé en ce que
    le déplacement défini de la tige de piston (18) est dû à l'actionnement d'une mécanique de changement.
  24. Applicateur selon la revendication 15,
    caractérisé en ce que
    la surface supérieure provoque dans la chambre de dosage (92) une action d'adhérence et/ou capillaire accrue pour retenir le fluide à appliquer dans la chambre de dosage (92).
  25. Applicateur selon la revendication 15,
    caractérisé en ce que
    des moyens ou des éléments supplémentaires existent dans la chambre de dosage (92), qui ont une action d'adhérence et/ou capillaire sur le fluide à appliquer.

  28. Applicateur selon la revendication 27,
    caractérisé en ce que
    l'action d'adhérence et/ou capillaire variable est obtenue par des fibres et/ou des poils de brosse devenant plus minces, ou par des fibres et/ou des poils de brosse se divisant.
