Abstract

A colouring instrument comprises an elongate open ended tubular casing (1) which houses a chamber (2) containing a quantity of water or water including a coloured dye. A nib (4) of fluid absorbent material protrudes from one open end of the casing and a liquid absorbent wick (3) connects the nib to the liquid present in the chamber A stick of a water soluble pastel (10) protrudes from the end of the casing remote from the nib to enable a user of the instrument to produce water colours using just one instrument.

Description

COLOURING INSTRUMENT
This invention relates to colouring instruments and more especially to a colouring instrument which enables the user inter alia to blend colours by a colour washing technique using a single colouring instrument.
Colour washing is a technique used by artists to create an artistic blending of colours. One example of this technique is the use of water colours in which swatches of dry pastel on a sheet of drawing material are softened with a brush dipped in clear water or water to which a pigment has been added.
Presently, several instruments are required to produce a colour wash effect, these including a set of pastels, a brush for applying water and a container for the water. The need for a separate brush and a source of water essentially means that the opportunities for producing water colours are limited especially when, for example, travelling where no stable supporting surface is available. It has been found that art products provide useful diversions for children and adults alike during lengthy periods of time when travelling by air or other means.
One object of the present invention is to provide in a single instrument all that is required for a user to achieve high quality colour blends and washes. Additionally, pens in accordance with the present invention enable the user to produce pastel drawings and coloured ink drawings.
The idea of providing a pen which includes two colouring media is disclosed in US 2007/0110499 Al. The pen disclosed in this document comprises a hollow pen-holder having at one end a watercolour pen and at the other end a wax crayon. The disclosed pen is said enable the user to produce two painting effects, these being a drawing in the colour of the watercolour protruding from one end of the pen or a drawing in the colour of the crayon. Such a pen would be unable to produce a colour wash effect because swatches of colour laid down by a conventional wax based crayon cannot be blended or softened simply by brushing with water or water to which a pigment has been added.
In one aspect the invention provides a colouring instrument which comprises an elongate tubular casing which houses a chamber containing a quantity of water or water including a coloured dye, a nib of fluid absorbent material protruding from one open end of the casing and a stick of a water soluble pastel protruding from the other end of the casing, and a liquid absorbent wick connecting the nib of fluid absorbent material to the liquid present in the chamber.
A water soluble crayon is one which generally comprises a colouring agent, a binder and one or more water soluble ingredients.
Pens having nibs of fluid absorbent material are well known. These pens include marker pens which generally comprise a tubular housing from one end protrudes a fibrous felt-like nib connected through a liquid absorbent wick to an internal chamber or transorb which contains a fluid indicator such as ^a water-based ink containing a coloured dye. As the marker pen is used the fibrous nib is replenished with ink which travels under capillary action to the nib.
Marker pens come in several colours but the use of each is limited to laying down one colour at any given time.
In another aspect the invention provides a colouring instrument in the form of a marker pen, the pen comprising an open ended elongate casing divided into two separate chambers by an internal wall, the first chamber being closed at its end remote from the internal wall by a nib of absorbent material and a quantity of water or water to which has been added a colorant, a liquid absorbent wick connected between the nib and the liquid present in the first chamber, and a water soluble pastel retained within and protruding from the open end of the second chamber.
The colorant preferably comprises an ink.
The nib may have a rounded, pointed, wedge-shaped or brush shaped contour.
The protruding surface of the water soluble pastel may permanently protrude from the end of the casing remote from the absorbent nib or, alternatively, be selectively moved to so protrude from a position within the boundaries of the housing by traction means. When not in use, one or both ends of the housing may be closed by removable caps.
The invention will now be described by way of example only with reference to the accompanying drawing in which the sole Figure shows a section through an instrument in accordance with the invention.
The illustrated instrument comprises a hollow elongate tubular housing 1 of a plastics or like material having an elongate chamber 2 in which is retained a reservoir 3 of water or a water-based colorant such as coloured ink. A fibrous felt-like liquid absorbent nib 4 is connected to the reservoir through a liquid absorbent capillary wick 5. The nib 4 protrudes from the open end of the chamber 2 and the housing 1 via an opening 6. The outer boundary 7 of the housing 1 is of reduced diameter to receive a cap (not shown).
The contour of the nib 4 maybe rounded, pointed, wedge-shaped or shaped as a brush. The exposed surface of the nib may be smooth or roughened.
The end of the chamber 2 remote from the opening 6 is closed by a wall 8. This wall 8 forms the base of a second chamber 9 in which is located a stick of water soluble pastel 10. The end of the pastel remote from the wall 9 protrudes from the end of the housing 1 remote from the nib 4. The exposed end of the pastel 10 may be covered by a cap when not in use or may be withdrawn into the housing by a traction device (not shown).
The composition of the water soluble pastel conveniently comprises fatty acid, fatty alcohol, polyethylene glycol, talcum powder and a dye. In one arrangement the composition comprises a mix of a surfactant, emulsifying and solubilising agents, and solvents. A preferred composition comprises alcohol-polyoxyethylene, polyethylene glycol stearate and polypropylene glycol. Typically the pastel mix comprises by weight between 20% and 40% alcohol-polyoxyethylene ether, between 40% and 60% polyethylene glycol stearate, and between 10% and 30 % polypropylene glycol. A preferred composition by weight comprises approximately 30% alcohol-polyoxyethylene ether, approximately 50% polyethylene glycol stearate, and 20% polypropylene glycol.
That part of the instrument which does not include the water soluble pastel conforms essentially to a conventional marker pen.
In use, the pastel end of the instrument is used to create a coloured image on a sheet of drawing paper or the like. The instrument is then turned through 180 degrees and the absorbent nib applied to the coloured image to produce a wash or blend of the colours of the crayon and the colorant absorbed by the nib 4.
In practise, a set of, say, sixteen instruments as described would be available to the user to enable a vast range of colour blends to be achieved. The or each instrument can be used by artists to create a colour blending effect. They can also be used by less skilled adults and children alike to produce blending effects normally associated with professional artists.
It will be appreciated that the foregoing is merely exemplary of instruments in accordance with the invention and that modifications thereto can readily be made without departing from the true scope of the invention.
