Abstract: The packaging is particularly suitable for containing hair coloring components, namely the hair color 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 in 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.

Abstract: The disclosure relates to a device for performing routine urinalysis.

A cannula (42) may be pierced through the stopper (12) in the area of the opening (20) of the first chamber (14) and can simultaneously receive infusional solutions from the two chambers through two orifices (44, 46) spaced longitudinally from one another. The connection between the cavity (34, 40) in the stopper (12) may be established in one embodiment by means of a connecting cannula (56) with orifices (58, 60).

Abstract: There is provided a two-compartment container. A lower mixing compartment has a closure which seals that compartment, and the upper end of an upper compartment is disposed in the closure and communicates through the closure to an aperture therein. A lower slideable seal in the lower end of the upper compartment effects a seal between the two compartments. That seal is exitable from the upper compartment by means of a digitally powered linking means projecting from the aperture, whereby the contents of the upper compartment are dispersed into the contents of the lower compartment. The lower seal quickly exits from the upper compartment and the contents impinge upon the lower seal and deflect therefrom to more uniformly disperse into the lower compartment.
