Definitions

  • This invention concernsbrushes of the type comprising bristles provided upon a handle having a passage or channel therethrough which leads to the bristles and whereby fluid or paste can be supplied to such bristles.
  • a brush for the application of nail lacquer, with a holder constituting a container for the lacquer, in a channel in the handle of the brush serving to feed the lacquer to the bristles.
  • the bristles are fastened by their roots being clamped between two concentric light metal rings, the inner ring having a central opening which, when the bristles are secured to the handle, provides a continuation of the passage or channel in the handle.
  • the handle is formed of a resilient material and is provided with a cavity into which the unit, composed of the rings with the bristles projecting therefrom, is pressed.
  • the gripping of the bristles between two rings is not simple, and it is not always possible to ensure that all the bristles are properly clamped.
  • the brush is comparatively expensive to produce, and the fitting of the bristle and ring assembly into the cavity of the handle is difiicult and time consuming.
  • An object of this invention is to provide a construction wherein the bristles are secured to the handle in a very simple and convenient manner which simplifies the operation of fastening the bristles to the handle.
  • the present invention provides a brush comprising a handle, a tapering extension on one end of said handle, a channel extending through said handle and said extension, a cup-shaped end cap fitting onto said end of said handle, a hole in said end cap in correspondence with said extension so that said extension projects into said hole, and a bundle of bristles secured to said handle by the root ends thereof being accommodated in said hole and being gripped between the wall of said hole and said extension.
  • the material of the handle and the end cap is preferably polyethylene, since this material is resilient and comparatively flexible. Accordingly, there will be no tearing or splitting of the end cap upon insertion of the handle, and secure gripping of the end cap on to the handle and secure fastening of the bristles to the handle is assured.
  • a spigot is preferably provided, this having a pointed end and being adapted for insertion into the passage or channel of the handle with the pointed end protruding so as to constitute a continuation of the aforesaid extension.
  • FIG. 1 is a part-sectional side elevation of preferred embodiment of the brush of the invention.
  • FIG. 2 is a view similar to FIG. 1, but showing how the bristles are secured to the handle.
  • the brush comprises a handle 8, on one end of which is provided a cup-like end cap 1 having a thickened base 3 and defining an axial cavity 2 for receiving the handle, an axial hole 4 of diameter smaller than that of the cavity 2 being provided in the base 3.
  • the hole 4 serves to accommodate a bundle of hairs or fibres 5, the root ends 6 of which extend into the cavity 2.
  • the end cap 1 is preferably made of polyethylene, but it can, of course, be made of other suitable materials.
  • the handle 8 is of circular cross-section and has an outside diameter such that it is a tight push fit into the end cap 1, so that no adhesive is necessary to secure the end cap 1 fast onto the handle 8, although adhesive can, if desired, be employed.
  • That end of the handle 8 which is intended to be secured into the end cap 1 has an axial frusto-conical extension 10 of small diameter, surrounded by an annular end face of the handle.
  • the greatest diameter of the cone 10 is smaller than the internal diameter of the hole 4 in the base 3 of the end cap 1, and when the handle 8 is inserted into the cavity 2, as shown in FIG. 2, the extension 10 is aligned with the hole 4.
  • the handle 8 has an axial bore or channel 11 which extends through the extension 10.
  • a metal spigot 13 is inserted into the channel 11 of the handle 8, this spigot 13 having a pointed end 14 which, when the spigot 13 is properly inserted, just projects from the extension 10 and constitutes an efiiective continuation thereof.
  • the spigot 13 is an easy sliding fit in the channel 11 so that it can readily be withdrawn therefrom.
  • the handle 8 is forced into the end cap 1, as indicated in FIG. 2.
  • the point 14 of the spigot 13 reaches the roots 6 of the fibres or hairs 5, it separates the latter and spreads them out, and as the handle 8 moves further into the cap 1, the extension 10 penetrates into the roots 6 and spreads them further.
  • the outspread roots 6 are engaged by the annular end face 9 of the handle which presses them towards the annular surface 15 of the bottom of the cavity 2, while the extension 10 enters into the hole 4 and forces outwards those parts 12 of the bristles which are within the hole 4.
  • the handle 8 is eventually forced fully into the cap 1, as shown in FIG.
  • Polyethylene is a suitable material for the parts of the brush, but, the handle and cap can, if desired, be of any other suitable material, such as metal.
  • a brush comprising, a handle having an end face, a tapering extension projecting centrally from and integral with the end face of said handle, a channel extending through said handle and extension, 9. cup-shaped end cap sleeved upon said handle for enclosing the end face of said handle, said end cap having an inner bottom wall coplanar with the end face of said handle and having an opening therethrough in alignment with said extension for the extending of said extension thereinto, a bundle of bristles having root ends and being secured relative to said handle by the accommodation of the root ends through thebp'ening of said end cap and the gripping thereof between the wall of the opening of said end cap and extension with said extension extending into the bristles of said bundle 5 thereof and with the innermost ends of the bristles of said bundle thereof being forced into confronta tion with the inner bottom wall of said end cap by the end face of said handle, and a removable spigot having a pointed end andhaving a sliding fit in said channel for spreading the root ends of the said bristles
