  • the present invention relates to a dispensing device, in particular for dispensing a first and / or second fluid, according to the present claim 1.
  • the dispenser according to the invention should generally be usable for cosmetic products with a plurality of adjustable components, in particular for the variable setting of sunscreens with different sun protection factors.
  • a dispensing device which comprises two containers which are each intended to contain a product, and two pumps associated with these containers each having a movable control member.
  • the actuation of the control member causes the delivery of the product contained in the associated container by the corresponding pump.
  • the dispensing device comprises a push button, at least one control member associated elastically deformable transmission member which is arranged so that it transmits a movement of the push button on the control member to deliver the product, and at least one adjusting member, the setting of theriessdorfd ein at least the allowed the transfer member associated control member.
  • the transmission member is arranged such that it deforms when the associated control member imposed by the adjusting Achieved way end position of the other control member, so that the push button is allowed to move on, and take this other control body.
  • the adjusting member comprises for this purpose a wall which is arranged rotationally cylindrical relative to the longitudinal axis of the device, wherein at the radially inner surface of a plurality of tongues are arranged, which - like the adjusting member itself - are formed from a deformable material.

Furthermore, by means of the dispenser according to the invention, the user can make the dispensing ratio of the two fluid components variable within a predetermined bandwidth.
  • the fluid containers are coded against each other, such as with the help of different Nut- or fits or similar systems. In this way it is prevented that two "equal" fluid containers, ie fluid containers with identical contents, are fastened to the correspondingly configured neck part of the head assembly.
