  • the bag is replaced by another pocket.
  • the charging socket would only be used for the initial filling of the pocket at the factory for example or the pocket may be devoid of it.
  • the dispensing head 60 is thus configured to open or close the shutter 70.
  • the product dispenser 50 is thus configured to take an opening configuration, in which the shutter is open (as illustrated for example by figure 5 ) and the product is distributed, and a configuration of closure (as illustrated by figures 1 and 6 ), in which the shutter is closed.
  • the product dispenser 50 moves from the closure configuration to the opening configuration by moving the dispensing head 60 from a stable position to an unstable position which drives the head plate 74, the dispensing head 60 moving from the unstable position at the stable position, notably thanks to a return element 73.
  • the stable position corresponds to a so-called high position
  • the unstable position corresponds to a so-called low position
  • the dispensing head 60 moves from the stable position to the unstable position if a user presses on it.
  • the displacement of the dispensing head 60 induces, via the head plate 74, a crushing of the bellows 72 which opens a passage between the upper neck 72a of the bellows 72 and the clasp 71, in particular the plate 71a, as shown in FIG. illustrates the figure 5 .
  • the return element 73 pushes the head plate 74 which drives the dispensing head 60, causing the bellows 72 to expand and the bellows upper neck 72a comes into contact with the clasp 71, in particular with the plate 71a.
  • the bag delivers product to the dispensing head under the effect of the pressure to which the bag is subjected.
  • variable-volume reservoir constituted by the flexible pouch described above could comprise instead of the flexible pouch a device such as that described, for example, in the patent application.
  • FR 2 869 771 namely a tank formed of rigid parts and some movable relative to others.
  • This tank would then comprise a cylindrical tank with an opening pointing downwards, and a movable plate that moves in the tank as the product is issued.
  • the pressurizing system 80 of the present application would act on the movable platen.
  • the tank, the bottom of the press and / or the inner housing could form a single piece.
  • the pressurizing system 80 of the present application comprises a spring or other elastic return device which acts alone or in combination with a foam block.
