COLOURING DEVICE Russian patent published in 2010 - IPC B43K8/04 B43K27/00 B43K11/00 

FIELD: physics.

SUBSTANCE: colouring device has a first soft-tip pen which has a casing with an absorbing tip containing liquid or dye of a first colour, a second soft-tip pen which has a casing with an absorbing tip containing liquid or dye of a second colour. The casings of the soft-tip pens have size and shape which enables joining with opposite ends of a tubular mating element such that, their absorbing tips are at a distance from each other. There is a device which enables relative movement between the soft-tip pens when there are in position inside the mating element, that way forcing the absorbing tips to selectively come into contact with each other inside the mating element and freeing up from such contact.

EFFECT: use of the given invention makes it possible to successively draw lines or sequence of lines, uniform or successive change in colour from one colour to another.
