  • the end face 6 is then flat rests on the corresponding outer surface of the sealing socket 25.
  • this embodiment forms a toothed region identified by the arrow 28.
  • the springs 12 consist of straight helical spring arms 12 and the spring 22 is designed as a helical spring.
  • the helical spring arms 12 used and the tension spring 22 are distinguished by a particularly low overall height.
  • the individual components, i.e. H. the application head 2, the plunger element 3 including the spring arms 12 and the fastening ring 13 as well as the container 18 and also the spring 22 can be injection molded from a thermoplastic material, for example polypropylene.
  • a membrane 29 it can advantageously consist of polypropylene.
  • other materials than plastic for example metals, rubber, silicones or similar elastic spring materials, can also be used.
  • the membrane 29 can be sufficiently firm and designed as a spring.
  • the spring arms 12 can be integrated.
  • a ventilation opening penetrating the wall 15 can be formed below the space of the application head 2 covered by the membrane underside 30, for example as a bore, in order to provide a ventilation opening in this area To enable membrane caused ventilation.
  • the air in this area has a kind of shock absorber effect.
  • the sealing socket 25 can also be formed in a trough-shaped recess in the sealing cap 24, so that in the closed or storage position the plunger element 3 protrudes beyond the adhesive application surface 16 - approximately halfway between it in the figures 1 and 3 shown position - comes in sealing cap with the sealing socket 25.

Abstract

L'invention concerne un dispositif d'application (1 ; 1' ; 1'') servant à appliquer, au choix, un fluide liquide ou visqueux, en particulier un fluide gélatineux, sous la forme de points/lignes ou en nappe sur un substrat qui comporte une surface d'application de fluide (16) permettant une telle application, ainsi qu'un conduit d'application de fluide (4) qui peut être déplacé dans l'axe longitudinal par rapport à ladite surface, vers une position de distribution de fluide qui permet une application sous forme de points ou de lignes. L'objectif de cette invention est de concevoir une solution qui permet de simplifier le passage d'une application sous forme de points/lignes à une application en nappe et vice versa. A cet effet, le conduit d'application de fluide (4) et/ou la surface d'application de fluide (16) peut/peuvent être déplacé(e)s d'une première position de distribution de fluide vers une deuxième position de distribution de fluide, sous l'action d'une force de rappel. En outre, le conduit d'application de fluide (4) et/ou la surface d'application de fluide (16) est/sont monté(e)(s) sur le dispositif d'application (1 ; 1' ; 1'') de façon à pouvoir être remis(e) dans une des deux positions, sous l'action de ladite force de rappel.
