The invention claimed is: 1. A hair treatment fluid application device comprising; an applicator body having outlet orifices for applying said hair treatment fluid to hair, a flexible container for containing said hair treatment fluid, said flexible container having a passage opening for allowing egress of said hair treatment fluid from said flexible container to said applicator body a housing for accommodating said flexible container, pressure means for exerting pressure on said flexible container for forcing said hair treatment fluid from said flexible container through said passage opening to said applicator body by deforming said flexible container, and driving means for driving said pressure means, wherein said pressure means comprises an air pump for increasing air pressure within at least part of said housing. 2. A device as claimed in claim 1, wherein said pressure means are located within said housing. 3. A device as claimed in claim 1, wherein said passage opening is embodied by a one-way valve member. 4. A device as claimed in claim 1, wherein said housing is provided with a one-way valve member for hair treatment fluid which has issued through said passage opening to the exterior. 5. The device of claim 1, wherein the driving means comprises an electric motor for driving the air pump. 6. The device of claim 5, further comprising a switch external to the housing for selectively supplying electric power to the electric motor. 7. The device of claim 5, wherein said electric power is supplied by a battery disposed with the housing. 8. The device of claim 1, wherein the housing comprises a first part for holding the flexible container, and a second part for gripping the device, the first and second parts being separated form each other by a separating plate. 9. The device of claim 8, wherein the air pump is disposed in the second part of the housing and the air pump increases the pressure within the first part of the housing. 10. The device of claim 9, further comprising a one-way air valve between the first and second parts of the housing, wherein the air pump supplies air to first part of the housing through the one way air valve. 11. The device of claim 8, further comprising a rotatable hinge connecting the first part of the housing to the second part of the housing. 12. The device of claim 8, further comprising a one-way air valve between the first and second parts of the housing, wherein the air pump supplies air to first part of the housing through the one way air valve. 13. The device of claim 1, wherein the housing comprises: a first part defining a first cavity for enclosing the flexible container therein; and a second part defining a second cavity for enclosing the air pump and driving means therein, the first and second cavities being separated from each other by a separating plate. 14. The device of claim 13, further comprising a one-way air valve between the first and second parts of the housing, wherein the air pump supplies air to the first part of the housing through the one way air valve. 15. A hair treatment fluid application device comprising a flexible container for containing said hair treatment fluid, an applicator body having outlet orifices for applying said hair treatment fluid to hair, said flexible container having a passage opening for allowing egress of said hair treatment fluid from said flexible container to said applicator body and a housing for accommodating said flexible container, characterized by pressure means for exerting pressure on said flexible container for forcing said hair treatment fluid from said flexible container through said passage opening to said applicator body by deforming said flexible container, and by driving means for driving said pressure means, and characterized in that said part of said housing is provided with air release means for releasing air from said housing as soon as the air pressure within said part of said housing exceeds a certain threshold value.
