1. A powder compact comprising a case forming a main make-up powder receptacle and an applicator head fitted to said case, said applicator head comprising a porous membrane occupying the top part of said head and an auxiliary powder receptacle used to retain part of said powder close to said porous membrane, said porous membrane being designed to come into contact with the skin to dispense said powder on said skin, wherein said powder compact comprises a cylindrical wall which surrounds a communication channel through which said auxiliary powder receptacle communicates with said main powder receptacle and at least one section of which is occupied by a sieve disposed between the main powder receptacle and said auxiliary powder receptacle, said sieve having a mesh adapted to the particle characteristics of said powder in order to control its flow. 2. A powder compact according to claim 1, wherein said porous membrane has a substantially axisymmetric shape around an axis and said communication channel between said case and said head has said axis of symmetry as its axis. 3. A powder compact according to claim 1, wherein the case and the auxiliary powder receptacle are also axisymmetric around said axis. 4. A powder compact according to claim 3, wherein the diameter of said communication channel is greater than half of the internal diameter of the case. 5. A powder compact according to claim 1, wherein the case has a bottom and a side wall with an open end on which the applicator head is fixed reversibly, said applicator head being provided with a fixing skirt that can be fitted inside and/or outside the open end of the side wall of said case, the fixing skirt of the applicator head and the side wall of the case being provided with complementary and substantially reversible means of being unified. 6. A powder compact according to claim 1, wherein the pattern of the sieve mesh corresponds to an opening whose shape factor is lower than 2 and of which the largest dimension is between 50 μm and 1500 μm. 7. A powder compact according to claim 1, wherein said sieve is made from a woven polyolefin. 8. A powder compact according to claim 1, wherein said sieve is treated so as to have physical and chemical properties suitable for using said powder. 9. A powder compact according to claim 1, wherein the communication channel is provided with a plurality of n sieves, with number n ranging between 2 and 20. 10. A powder compact according to claim 9, wherein the closer the sieves are to the porous membrane, the more the dimensions of their meshes decrease. 11. A powder compact according to claim 1 also provided with a lid designed to be placed so as to be removable above said porous membrane in order to isolate said porous membrane from the outside. 12. A powder compact according to claim 1, wherein said sieve is placed on the end of said communication channel which is closest to the porous membrane. 13. A powder compact according to claim 12, wherein a second sieve, or a perforated transverse wall, is placed on the other end of said communication channel. 14. A powder compact according to claim 1, wherein the applicator head also comprises a ring-shaped support which surrounds the cylindrical wall which bounds the communication channel, the ring-shaped support being used as support for said porous membrane, at least in the peripheral part of said porous membrane. 15. A powder compact according to claim 14, wherein said ring-shaped support is a pad made of highly-flexible synthetic foam, of type “NBR soft or SBR soft”. 16. A powder compact according to claim 14, wherein said ring-shaped support, is a funnel-shaped part, made from an elastomer with a cylindrical part fitting around the cylindrical wall which bounds the communication channel and a tapered part, which is adjacent to said cylindrical wall and which flares out towards the porous membrane so that its flared end acts as support for the periphery of the porous membrane. 17. A powder compact according to claim 1, wherein said communication channel has a diameter close to that of the porous membrane, the end of the communication channel which is closest to said membrane being provided with a perforated rounded shell, whose concavity is directed towards the receptacle and which is used as support for said porous membrane. 18. A powder compact according to claim 17, wherein said perforated rounded shell is said sieve, the mesh of which is adapted to the particle characteristics of said powder. 19. A powder compact according to claim 18, wherein said communication channel is provided with a second sieve, the mesh of which is preferably finer than that of the first sieve which is used as support for said porous membrane. 20. A powder compact according to claim 1, wherein the largest dimension is between 80 μm and 800 μm.
