Painting brush

Abstract

There is provided a decorating painting brush head comprising a ferrule and a filament cluster. The ferrule comprises a brush handle receiving end and a filament cluster emerging end. The filament cluster comprises a retained end and a free end. The retained end of the cluster is retained in the ferrule by a setting block. The filament cluster includes a filament-only region at the emerging end of the ferrule, and the emerging end of the ferrule comprises a constriction for shaping the filament cluster towards the free end.

1 . A decorating painting brush head comprising a ferrule and a filament cluster, the ferrule comprising a handle receiving end and a cluster emerging end, one end of the cluster being set into a setting block, the block extending in the ferrule to a level towards the emerging end, the level being spaced from the emerging end to define a filament-only region in the ferrule, the ferrule being tapered from the handle receiving end to the cluster emerging end and pushing the filament-only region of the cluster inwards, whereby to cause the cluster to taper beyond the emerging end. 
     
     
         2 . A brush head as claimed in  claim 1 , in which the filament cluster has a generally quadrilateral section. 
     
     
         3 . A brush head as claimed in  claim 1 , in which the cluster has a generally rectangular section. 
     
     
         4 . A brush head as claimed in  claim 1 , in which the cluster tapers in width. 
     
     
         5 . A brush head as claimed in  claim 1 , in which the cluster tapers in depth. 
     
     
         6 . A brush head as claimed in  claim 1 , in which the ferrule is a band. 
     
     
         7 . A brush head as claimed in  claim 1 , in which the ferrule is formed from steel. 
     
     
         8 . A brush head as claimed in  claim 1 , in which the ferrule is formed from a strip of material. 
     
     
         9 . A brush head as claimed in  claim 1 , in which the ferrule is tapered along at least part of at least one dimension. 
     
     
         10 . A brush head as claimed in  claim 9 , in which the ferrule is tapered longitudinally and/or latitudinally. 
     
     
         11 . A brush head as claimed in  claim 1 , in which a filament end of the ferrule is inwardly converged. 
     
     
         12 . A brush head as claimed in  claim 1 , in which part of the ferrule is inwardly bent or crimped to exert a shaping force on the filament. 
     
     
         13 . A brush head as claimed in  claim 1 , in which a filament end of the ferrule is bent or crimped to exert a shaping force on the filament. 
     
     
         14 . A brush head as claimed in  claim 1 , in which the resin block further comprises one or more plugs. 
     
     
         15 . A brush head as claimed in  claim 1 , in which the setting block is positioned at least 7 mm below the end of the ferrule. 
     
     
         16 . A decorating painting brush comprising a brush head as claimed in  claim 1  together with a handle. 
     
     
         17 . A decorating painting brush head ferrule for receiving a filament cluster, the ferrule comprising a handle receiving end and a cluster emerging end, the ferrule being tapered from the handle receiving end to the cluster emerging end such that, in use, the ferrule can push a filament cluster inwards, whereby to cause the cluster to taper beyond the emerging end.
