Definitions

  • the present invention relates to a bristle head cassette comprising a cassette collar and a paintbrush kit comprising such bristle head cassette, a handle and a connector for connecting the bristle head cassette to the handle via the cassette collar.
  • the conventional paintbrush has both a handle and a bristle head/bristle pack including a bundle of bristles, which is able to hold therein a paint by adhesion as well as capillary forces.
  • Bristles may be natural or synthetic filaments, wherein synthetic filaments, i.e. monofilaments, can be produced from a wide variety of thermoplastic polymers, in a wide variety of configurations including solid and hollow, and in a wide variety of cross-sections, including circular, oval, triangular, trilocular, tetralocular, lobate, or may contain multiple voids.
  • synthetic filaments i.e. monofilaments
  • thermoplastic polymers in a wide variety of configurations including solid and hollow, and in a wide variety of cross-sections, including circular, oval, triangular, trilocular, tetralocular, lobate, or may contain multiple voids.
  • the bristle head is permanently attached to the handle such that the bristle head cannot be separated from the handle.
  • bristles are permanently attached to the handle using a ferrule, which is a metallic clamp that surrounds a lower portion of the bristles and an upper portion of the handle to bind the bristles to the handle. This is conventionally done by inserting one end of the bristle pack into the ferrule and then applying an adhesive against the end of the bristle pack inside the ferrule.
  • Paintbrushes featuring different bristle heads may be useful for different purposes. Therefore, a user normally purchases and maintains separate paintbrushes having heads of various sizes, shapes, and materials. The result can require a significant investment in tools.
  • U.S. Pat. No. 8,250,715 B attempts to overcome this disadvantage by disclosing a paint brush having a detachably interconnected handle and bristle head.
  • This system allows for detaching and replacing bristle heads from the handle.
  • This system has the disadvantage of not being compatible with the current way of assembling a paintbrush by use of a ferrule, limiting the application of each bristle head to be used with handles with only one type of connector having a specific and non-standardised design.
  • epoxy adhesive usually an epoxy adhesive is used, wherein it is commonly known that epoxy resins in their liquid and uncured state are mostly classed as irritant to the eyes and skin, as well as toxic to aquatic organisms. Exposure to epoxy resins can, over time, induce allergic reactions. Sensitization generally occurs due to repeated exposure (e.g. through poor working hygiene and/or lack of protective equipment) over a long period of time. Furthermore, epoxy adhesives used for paint brush manufacturing is known to have a long curing time, usually several hours.

  • the snap-fit connection 82 may be continuously or discontinuously extending around the inside of the connector 80 .
  • the snap-fit connection 82 extends radially inwards of the connector 80 .
  • a paintbrush handle 70 comprising flexible members 83 for connecting with the bristle head cassette 20 is illustrated.
  • the wall defining the recess 72 in the handle 70 is divided into multiple flexible members 83 .
  • the flexible members 83 also work as a snap-fit connection 82 comprising a protruding edge 84 and a snap-in area 85 provided on an inside surface of the recess 72 in the first end 71 of the handle 70 .
  • the snap-fit connection edge 84 may be continuously or discontinuously extending around the inside of the connector 80 /wall of the recess 72 .
  • the snap-fit connection 82 extends radially inwards of the connector 80 /wall of the recess 72 .
  • the snap-fit connection 82 above may be ratchet-like, e.g. by using more than one connection edge 84 on the outside of the cassette collar 20 and/or the inside of the connector 80 /wall of the recess 72 , whereby the cassette collar 20 may be optionally introduced into the handle 70 at/with different locations/depths of the recess and even be moved in and out of the recess 72 to enable differing/varying total lengths of a paint brush after assembly to the paint brush.
  • the outer circumferential shape of the cassette collar 20 is adapted to the way that it should be connected to the handle 70 and/or the connector 80 .
  • the connecting parts on the handle i.e. the connector integrated in the handle, may be made from any suitable polymer or thermoplastic polymer, including polyamides, polyesters and/or polyolefins.

It is thus not necessary to use neither an adhesive nor a metal ferrule for connecting the bristle head to the paintbrush handle. Further, as the paintbrush only comprise one type of material it could be recycled without the need of disassembly of the paintbrush into different parts.
  • the bristle head cassette 1 comprise two or more cassette collars 20 connected to each other.

In this way, the bristle head cassette 1 could be build up with different features in different parts and by pre-manufactured standard cassette collars 20 .
  • the bundle of bristle 10 connected to different cassette collars 20 comprise different mixes of bristles.
  • the different mixes of bristles can according to an aspect be one or more of the diameter of the bristles, the cross section of the bristles, the length of the bristles and the material of the bristles.
  • the same type of cassette collars 20 could be used to manufacture paintbrushes of different size by changing the number of cassette collars 20 and how they are connected to each other.
  • the cassette collar 20 is connected side by side in the bristle head cassette 1 , put in another way the cassette collar 20 is connected to each other as pieces of a jigsaw puzzle.
  • a first cassette collar 20 is connected to a second cassette collar 20 such that it surrounds the second cassette collar 20 , i.e. put in another way the different cassette collar 20 are connected do each other to be similar to layers on an onion.
  • the two or more cassette collars 20 is connected to each other and the bundle of bristles 10 by being exposed to a laser, i.e. that the laser melt part of the cassette collars 20 and the bristles in the bundle of bristles 10 such that they fuse together.
  • the further cassette collar 20 is connected to at least one cassette collar 20 and/or bundle of bristles 10 .
