<p>The packaging is particularly suitable for containing hair colouring components, namely the hair colour itself and a second fluid, usually peroxide, which must be stored separately and well mixed immediately before being applied to the hair. The two fluids, for storage purposes, are housed in two different concentrically disposed containers (1, 6). Immediately before hair treatment the inner container (6), the base of which is adjacent the base member (2) of the outer container (1), is displaced outwardly as far as a stop (8) and thus simultaneously a good mixing of the two fluids is effected. A sealing lip (17), which releases possible overpressure, a deformable base member (2), and a groove (21) prevent the occurrence of overpressure inside the two containers.</p> |
