DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to an applicator for applying various fluid products, for example for applying colorants to hair.
BACKGROUND OF THE INVENTION
The application of treatment fluids to hair requires skill and practice if good results are to be achieved. The quality of the result is often dependent upon the skill and precision with which the treatment is applied, and so an applicator which helps a hairdresser to control the application of a fluid is beneficial in achieving a desired result.
It is already known for a hairdresser to place a prepared treatment fluid into a plastic container provided with a nozzle through which the fluid may be squeezed on to the hair. Although this method of application is convenient and less messy than applying the fluid from a bowl using a brush, if a very fine nozzle is used to achieve a precise line of treatment, the rate at which fluid can be expelled from such a nozzle makes the application slow. Also, it can be difficult to ensure that the treatment is applied to the correct parts of the hair.
DE-A-3743713 discloses a hairbrush having a plurality of substantially parallel bristles some of which are hollow whereby a treatment fluid from a container embodied in the brush can be fed into the user's hair.
It would be desirable to be able to provide an alternative form of fluid applicator which overcomes some at least of the problems encountered with current forms of applicator, and in particular which enables accurate control in the application of the fluid to a substrate.
SUMMARY OF THE INVENTION
According to the present invention, there is provided an applicator for applying a fluid to a substrate comprising a reservoir for containing a treatment fluid, at least two nozzles spaced apart from one another and generally parallel with one another, and a passage connecting each of said nozzles to the reservoir, characterised in that the nozzles are each movable between an open position in which a bore therethrough communicates with the interior of the reservoir, and a closed position in which flow of fluid therethrough from the reservoir is prevented.
The provision of at least two spaced apart nozzles allows fluid to be applied to at least two separate areas simultaneously, which has particular advantages when used to apply color in the form of "highlights" or "lowlights" to hair, because several narrow bands of color usually give a more natural-looking result than a single wider band.
Although the invention is described in terms of its suitability for use in applying hair treatments, its advantages may be beneficial in other uses such as in the application of decorative paint effects.
The reservoir may be an integral part of a complete container such as a tube or bottle in which the treatment fluid is contained. The reservoir is, however, preferably readily detachable from such a container so that it may be cleaned easily between applications. Most preferably, it is attached to and detachable from the container, for example by means of a screw-threaded connection or by a ridge provided on one of the reservoir and the container for engagement in a groove provided on the other of the reservoir and the container.
The applicator may be used with a wide variety of containers and fluid expulsion means. For example one type of suitable container has a piston-like plate which may be caused to move towards the nozzles to force the fluid contained in the container out of the nozzles by depressing a plunger to which the plate is attached, as in a syringe, or by activation of a sprung mechanism by depressing a trigger, for example. Alternatively, some form of pressured container may be used from which fluid may be expelled through the nozzles by applying gas pressure within the container.
A preferred type of container is a flexible tube or bottle from which fluid may be expelled by squeezing.
The reservoir is connected to at least two nozzles through which fluid may be expelled from the reservoir. Preferably at least three nozzles are provided, and
