Definitions

  • the invention relates to the field of pairs of capsules assembled together and respectively comprising two different phases to be mixed in order to obtain a personalized cosmetic product.
  • two capsules are introduced into a machine intended to mix the two phases they contain to produce a personalized ready-to-use cosmetic product.
  • the two capsules are arranged in the extension of one another, which allows total fluidity of the circulation of the mixture in the communication channel located between the two capsules.
  • EN 2894942 discloses a device for packaging and dispensing products to be mixed.
  • this total fluidity of circulation in the communication channel between the two capsules leads to a certain size of the mixing chamber containing these two capsules, especially in length.

  • the invention aims to provide a pair of capsules interconnected by a communication channel between capsules which comprises two transmissions at right angles, thus preferably forming the three sides of a rectangle.
  • the saving in space occupied by the capsules is substantial, the overall bulk being reduced, in particular in the direction of the length.
  • the reluctance to bend the communication channel between capsules for fear of hindering the fluidity of the circulation of the mixture inside the channel, is overcome; indeed, surprisingly, the mixture circulates sufficiently fluidly in the communication channel between the capsules despite the presence of the two bends at right angles.
  • this particular compactness with two bends at right angles to the communication channel makes it possible to facilitate a more efficient arrangement of two interesting functions of a machine in which the pair of capsules will be able to be introduced, namely a first function of expulsion of the contents of each capsule by pressure of a piston, the two pistons thus being able to be opposite each other, and a second function of heating the contents of the capsules by direct contact with a heating element which can thus be located just between the two capsules which can be arranged facing one another.
  • the present invention proposes a pair of capsules according to claim 1 dependent on claim 14.
