Abstract: A hair dye dispenser 10 for dispensing a fluid hair dye includes a dispensing container 12 for containing and dispensing the hair dye. The dispensing container 12 has a base 14 and at least one side wall 16, together defining an internal volume. The base 14 has a substantially flat upper surface and a lower surface with a plurality of projecting tines 24. One or more dispensing apertures 26 are distributed across the base 14. A piston 28 is configured to fit closely in sliding abutment with the wall 16 so as to be sealingly slidable towards the base 14. The dispenser 10 also includes a housing 30 formed with a socket 32 for removably receiving the dispensing container 12. An actuation mechanism 34 is associated with the housing 30, and configured to displace the piston 28 towards the base 14, thereby dispensing the hair dye through the dispensing apertures 26.

Abstract: A cartridge for use in a hair dye dispenser includes a dispensing container for containing and dispensing the hair dye, the dispensing container having a base and at least one side wall sealingly attached to or integrally formed with the base so as to define an internal volume of the dispensing container. The base has a lower surface that is formed with a number of projecting tines and at least one dispensing aperture. A piston is configured to fit closely in sliding abutment with the at least one side wall so as to be sealingly slidable towards the base.

Abstract: A cartridge for use in a hair dye dispenser includes a dispensing container for containing and dispensing the hair dye, the dispensing container having a base and at least one side wall sealingly attached to or integrally formed with the base so as to define an internal volume of the dispensing container. The base has a lower surface that is formed with a number of projecting tines and at least one dispensing aperture. A piston is configured to fit closely in sliding abutment with the at least one side wall so as to be sealingly slidable towards the base. The dispensing container and the piston are formed from polymer material, the piston being pressure-fitted within the dispensing container so as to define an initial position of the piston.
