Definitions

  • This invention relates to paintbrushes and more especially to a paintbrush whose handle or stem acts as a dispenser for dispensing controlled quantities of fluid to the bristles of the brush.
  • the invention also relates to dispensers for so dispensing fluids to the bristles of a paintbrush.
  • the fluids are typically water or water-based.
  • Paintbrushes are known in which a reservoir of water is contained within the brush stem or handle produced from a flexible material such as plastics. These brushes avoid the problems discussed above concerning open-topped water pots.
  • water is conveyed from the stem or handle to the brush bristles simply by squeezing the stem or handle. The rate at which water flows to the bristles depends upon the force applied to the stem or handle. This means that on occasions the water flow is excessive; the consequence of this is a reflection of the problem discussed above in the context of water pots.
  • the present invention sets out to provide a paintbrush, which overcomes, or at least alleviates, the disadvantages discussed above.
  • a paintbrush comprises a fluid receptacle having a body which is open at one end, a releasable plug for closing this open end which is formed with at least one aperture of an area equivalent to a diameter of between 0.5mm and 2.0mm (typically 1.0mm) through which fluid can leave the receptacle, a brush head connectable to the plugged end of the receptacle and including an open- ended ferrule for retaining a plurality of bristles and whose base is formed with one or more apertures for the flow of fluid from the receptacle to the bristles, and a chamber positioned between the apertures of the plug and the ferrule to receive fluid passing between the receptacle and the brush head.
  • the fluid is preferably water or a water-based fluid.
  • the bristles may be produced from a synthetic material such as nylon.
  • the nominal diameter of the bristles may be between 0.1mm and 0.2mm.
  • a preferred bristle diameter approximates to 0.15mm.
  • the packing density of the bristle ends within the ferrule is typically between 1.0 and 3.0 grams per square cm for a nominal bristle diameter of 0.15mm, an effective bristle length of around 21.0mm and a mean internal ferrule diameter of 6.5mm.
  • a preferred packing density approximates to 1.66 grams per square cm.
  • Folded bristles having an overall length of 55.0mm may be employed. The effective length of such bristles will be, however, 21.0 to 22.0mm.
  • the invention provides a paintbrush comprising a receptacle open at one end for retaining a quantity of fluid, a plug separable from and connectable to the open end of the receptacle, a brush head comprising a plurality of bristles secured within the open end of a ferrule and a skirted collar to which the underside of the ferrule is secured, means for attaching the receptacle to the collar of the brush head, and a chamber positioned between the upper surface of the plug and the undersurface of the ferrule, the plug and the undersurface of the ferrule including apertures for the flow of fluid from the receptacle to the bristles of the brush head with the diameter of the aperture or each aperture formed in the plug being between 0.5mm and 2.0mm.
  • a paintbrush comprises a fluid receptacle having a body which is open at one end, a plug for closing this open end which is formed with at least one aperture through which fluid can leave the housing, a brush head connectable to the plugged end of the housing and including an open-ended ferrule for retaining a plurality of bristles whose base is formed with an aperture for the flow of fluid from the receptacle to the bristles, and a porous member positioned between the apertures of the plug and the ferrule to restrict the flow of fluid from the housing to the brush bristles.
  • the fluid receptacle may be produced from a flexible material to enable the receptacle to be squeezed.
  • the porous member comprises a block of relatively inflexible material.
  • a preferred material is that marketed under the trade mark POREX. This is multiple porous material produced by or on behalf of Porex Technologies Corporation. Essentially it comprises a sintered mass of thermoplastic polymer pellets, especially micro-pellets made by rapid water quenched pelletising of the polymers.
  • the pellets are generally of uniform size and shape, each having approximately equal dimensions along three mutually perpendicular axes, have smooth surfaces, narrow pore size distributions, greater strength and other improved characteristics.
  • the invention provides a paintbrush comprising a receptacle open at one end for retaining a quantity of fluid, a plug separable from and connectable to the open end of the receptacle, a brush head comprising a plurality of bristles secured within the open end of a ferrule and a skirted collar to which the underside of the ferrule is secured, means for attaching the receptacle to the collar of the brush head, and a porous member positioned between the upper surface of the plug and the undersurface of the ferrule, the plug and the undersurface of the ferrule, including apertures for the flow of fluid from the receptacle to the bristles of the brush head.

  • Figure 9 is a second view of the underside of the brush head of Figure 7;
  • Figure 10 is a perspective view of a display tray including inter alia three of the illustrated paintbrushes.
  • the paintbrush illustrated in Figures 1 to 3 includes a flexible-walled water-containing receptacle 1 produced, for example, from a thermoplastics material, which is closed at one end 2 and has extending from its other end an open-ended neck 3.
  • a screw thread 4 is formed about the external periphery of the neck 3.
  • the neck is spaced from the main body of the receptacle by a tapered shoulder 5.
  • the upper open end of the neck is closed by a plug 6 whose downwardly extending annular wall 7 is dimensioned to project within the neck 3 to define a tight fit therewith.
  • the plug 6 may be removable or permanently located within the neck 3 of the receptacle 1. In a preferred arrangement the plug is a force fit within the neck to prevent or discourage removal.
  • the plug 6 is formed with a circular through-hole 8 whose diameter is between 0.5mm and 2.0mm. More than one such through-hole may be provided each having a diameter of between 0.5mm and 2.0mm.
  • the contour of the or each through-hole may be other than circular. In such cases, the area of the or each through-hole is equivalent to that of a circular through-hole having a diameter in the range 0.5mm to 2.0mm. Typically, the diameter of the or each through-hole is 1.0mm.
  • a brush head 9 Secured to the neck of the receptacle is a brush head 9 formed with an internally threaded collar 10. The threads of the collar compliment those of the neck 3 and co-operate to secure the brush head to the receptacle.
  • a tapered ferrule 11 for receiving a quantity of bristles 12 is upstanding from an internal surface of the ferrule base 14. The base of the ferrule is formed with one or more through-holes 15.
  • the bristles 12 are simply stapled to the internal surface of the base 14 of the ferrule 11. Effectively, the staple forms a know with the folded bristles. These are secured by punching the staple through the base 14 of the ferrule and/or by the interface fit of the densely packed bristles with the interior of the ferrule.
  • the bristles comprise folded strands of a synthetic material, typically nylon of nominal diameter between 0.1mm and 0.2mm. A preferred bristle diameter is 0.15mm. The nylon strands are densely packed into the ferrule.
  • the packing density is between 1.0 and 3.0 grams per cm 2 for a nominal bristle diameter of 0.15mm, a ferrule diameter of 6.5mm and an effective bristle length of 21mm.
  • effective bristle length is meant the height of the bristles along the base of the ferrule. Thus, before folding, these bristles are of a length equal to 42mm.
  • the selection of the diameter (or corresponding area) of the or each through-hole 8 within the range 0.5mm and 2.0mm is important. If the diameter is less than 0.5mm no or insufficient water will pass through the through-hole 8 and enter the chamber 18 for reasons of surface tension. If, on the other hand, the diameter of the or each through-hole is more than 2.0mm, too much water will pass through the hole or holes and into the chamber 18 and produce a flooding effect. A preferred through-hole diameter is around 1.0mm. It is an important feature of the invention that only controlled amounts of water pass from the receptacle and into the chamber 18. The selection of the bristle thickness is also important. Trials have shown that a bristle thickness of less than 0.10mm produces a choking effect on the required flow of water thereby inhibiting the flow of water whereas a bristle thickness of greater than 0.20mm produces an excessive water flow.
  • the plug 6 is removable from the end of the neck 3, filling of the receptacle 1 is simply achieved by removing the plug and then introducing water or other fluid in the receptacle through the neck 3. The plug is replaced and the collar is then screwed onto the receptacle and the paintbrush is ready for use. If the plug 6 is permanently or securely located within the neck, squeezing of the receptacle and placing the plug end in water causes water to flow by suction into the interior of the receptacle. To wet the bristles 12, the receptacle is shaken to cause a controlled flow of water to the through-holes 27 of the plug 6 into the chamber 18. As the brush is applied to a surface (i.e. a paint pad) water flows through the holes 15 and then by capillary action to the bristle ends.
  • a surface i.e. a paint pad
  • the paintbrush illustrated includes a squeezable water-containing receptacle 21 produced from a thermoplastics material which is closed at one end 22 and has extending from its other end an open-ended neck 23.
