Abstract

This invention relates to an instrument, preferably a marking instrument, for applying a fluid to a surface and particularly, though not exclusively, to a writing pen, including a marker pen, or a brush, especially an artist's brush. Other types of brushes are contemplated, such as those for applying cleaner, mouthwash or perfume to teeth. The instrument (2) comprises a tip (6), a holder for the tip (4), a cartridge (14) containing the fluid mounted within or connectable to the holder (4), and a manually-operable spray pump arrangement (10) for repeatedly dispensing a predetermined amount of the fluid under pressure from the cartridge (14) to the tip (4) of the instrument (2). A disposable or re-fillable cartridge for the instrument is also described.

AMENDED CLAIMS
[received by the International Bureau on 17 December 2001 (17.12.01); original claims 1, 17, 20 and 21 amended; remaining claims unchanged (5 pages)]
1 An instrument for applying a fluid to a surface comprising a fluid-applying tip, a holder for the tip, a cartridge containing a fluid to be applied mounted within or connectable to the holder, and a manually- operable spray pump arrangement for repeatedly dispensing a predetermined amount of the fluid under pressure solely by manual force from the cartridge to the tip of the instrument
2. An instrument according to claim 1 wherein the holder comprises a casing for the cartridge and a housing for the tip fitted together as a single unit
3 An instrument according to claim 2 wherein the holder is a tip housing to which the cartridge can be connecied
4 An instrument according to anv one of claims 1 to 3. of elongate configuration, wherein the pump arrangement is disposed longitudinally adjacent the tip of the instrument towards one end of the casing, and wherein the cartridge extends away therefrom and is accessible at the other end of the casing such that manual pressure exerted longitudinalK on the cartridge at that said other end is effective to operate the pump arrangement
5 An instrument according to claim 4 w herein a component of the pump arrangement is fixed longitudinalK w ithin the instrument casing and the cartridge is movable longitudinalK therew ithin to dispense the fluid
6 An instrument according to any one of claims 1 to 3. of elongate configuration, wherein transverse inward manual pressure on the instrument is arranged to move the cartridge and a component of the pump arrangement longitudinally relative to one another, thereby to effect said dispensing of the fluid
7 .An instrument according to claim 6. w herein the casing is provided with an inwardly-slidable member having a surface inclined to the longitudinal axis of the 25
