  • Another object of this invention is to provide a new and improved method of making a single-use, disposable brush having particular utility for gum massage or as a toothbrush.
  • Another object of this invention is to provide a new and improved method of making a single-use, disposable brush wherein the brush head dissolves in water.
  • the invention consists in the novel parts, steps, process, combinations, constructions, arrangements and improvements herein shown and described.
  • the present invention is directed towards a new and improved brush, which is preferably of the single-use, disposable type, and to a new and improved method for producing such a brush which comprises: forming a blank of sheet material with a plurality of radially spaced finger-like elements integrally connected to a common central segment, the finger elements and central segment being generally coplanar; placing a preformed piece of compressible material onto the central segment of the blank; folding the free ends of the finger elements around the compressible material and pressing them towards each other until the finger elements are substantially perpendicular to the common central segment, the finger elements thereby compressing and gripping spaced portions of the compressible material, the uncompressed portions of the compressible material extending radially from the finger elements so as to form a brush head; and sealing together. the portions of the finger elements remote from the brush head, at least at their ends and preferably throughout their entire lengths so as to form a handle for the brush.
  • the principles underlying the invention are not limited to such usage.
  • the method of this invention could equally well produce a shoe polish applicator, a clothes brush for removing lint and other foreign particles from clothes, or a carpet brush.
  • the method could be used to produce a brush wherein the compressible material of the brush head dissolves upon being immersed in water for a short period of time.
  • Such a brush would be ideally suited for cleaning toilet bowls since the brush head would dissolve upon completion of the cleaning function and could be disposed of by simply flushing the toilet.
  • Other uses will be readily apparent to those skilled in the art.
  • FIGURE 1 is a fragmentary top plan view of a blank of sheet material, formed into six finger elements preferably curved along their longitudinal edges, which constitute the brush head gripping means and handle means of a brush produced in accordance with this invention;
  • FIGURE 2 is a plan view of a suitable compressible material which constitutes the brush head of a brush to be produced in accordance with this invention
  • FIGURE 3 is a view taken along line III-III of FIG- URE 2, partly sectional and partly in elevation;
  • FIGURE 4 is a fragmentary elevation illustrating th compressible material shown in FIGURES 2-3 positioned on the central segment of the blank shown in FIGURE 1 and the free ends of the finger elements of the blank being folded about the compressible material, so as to compress and grip spaced portions of the material, the remaining uncompressed portions extending radially from between the finger elements;
  • FIGURE 5 is a perspective view illustrating a brush embodying this invention, and made in accordance with the method illustrated in FIGURES 14;
  • FIGURE 6 is an elevation of a modified brush produced in accordance with this invention, having two separate brush heads gripped by the finger elements;
  • FIGURE 7 is a fragmentary plan view illustrating modified configurations for the blank of sheet material and for the compressible material, for use in constructing a brush in accordance with the invention.
  • a blank of sheet material preferably of a substantially rigid plastic, or other suitable material, designated generally by reference numeral 10 is formed, by a suitable stamping, die-cut or molding operation, into a plurality of finger-like elements 12 integrally connected to and extending from a common central segment 14, and being geerally co-planar therewith.
  • Fingers 12 are preferably curved, as by scoring or other suitable means, along their longitudinal edges 15 so that when folded together (as more fully described hereinafter) the fingers will form an elongated handle member having a curvilinear transverse section, preferably circular in shape.
  • a preformed piece of suitable material which is to form a brush head, is placed onto the central segment 14 of the blank 10.
  • this material comprises a cellular, fibrous or foam sponge or sponge-like, compressible material 18, preformed into a cylindrical shape, as illustrated in FIGURES 2 and 3.
  • the free ends of fingers 12 are thereafter folded around the material 18 and are pressed towards each other until the finger elements are substantially perpendicular to the central segment 14.
  • the compressive pressure exerted by the fingers during the folding operation compresses and grips spaced portions of the material 18, the uncompressed portions being thereby caused to radiate in starlike fashion outwardly from between the fingers, thereby forming a brush head 20, comprising a series of longitudinal sectors 21.
  • Fingers 12 serve to firmly grip the compressible material forming the brush head and, when they are brought together and are thereafter bonded, or otherwise suitably sealed together, preferably form an elongated, generally cylindrical, handle member 25. When fingers 12 are thus brought together, the segment 14 of the blank 10 forms the end of the brush head, as illustrated in FIGURES 5 and 6. It will be understood that fingers 12 may be suitably sealed together along their entire length, or may be spot sealed at the ends only.
  • FIGURE 6 illustrates a modified brush constructed in accordance with the invention wherein a second piece of compressible material is also gripped by the fingers 12 in the manner previously described to form a second brush head 23 comprised of a series of longitudinal sectors 24.
  • FIGURE 7 illustrates a piece of compressible material 30 having a plurality of edges and the blank of sheet material 10 is formed with only four fingers 12.
  • the material 30 upon folding the fingers 12 together, the material 30 will be deformed and caused to radiate similar to the brush of FIGURE 5, except that the longitudinal edges of the brush head thus formed would be pointed rather than rounded.
  • a particularly suitable material is an expandable polystyrene foam, such as that sold under the trademark Styrofoam by the Dow Chemical Co., or an expandable cellular acetate material.
  • expandable polystyrene foam such as that sold under the trademark Styrofoam by the Dow Chemical Co.
  • cellular acetate examples of cellular acetate are sold under the trademarks Strux (Aircraft Specifications Co.) and Dylite (Koppers Co.).
  • Strux Aircraft Specifications Co.
  • Dylite Karls Co.
  • these materials when wetted expand to more than double their original size and yield a cellular, porous, resilient material which is ideally suited for massaging the users gums.
  • the material of the brush head may be impregnated with a suitable liquid or paste dentrifrice for cleaning the users teeth.
  • the brush head may be formed of watersoluble foam material, such as hydroxyethyl cellulose, polyvinyl alcohol or other equivalent water soluble foams.
  • these foams are sold under the trademarks Cellosize (Union Carbide Co.) and Vinol (Air Reduction Co.), respectively. It has been found that use of these materials in the brush head provides a brush ideally suited for use in cleaning toilet bowls. After usage for a short period of time, the head dissolves into a gelatinous mass and may be disposed of by simply flushing the toilet. For added cleaning power, the material may be impregnated or coated with a suitable detergent.
  • non-water-soluble foams would be suitable, such as, for example, polyurethane foams, expandable polystyrene foams, cellular acetate, and other equivalent 5 foams. Some examples of these foams have previously been stated.
  • a method for producing a brush which comprises: forming a blank of sheet material with a plurality of radially spaced finger-like elements integrally connected to a common central segment; placing a preformed piece of compressible material onto said central segment of said blank; folding the free ends of said fi ger elements around said material and pressing said finger elements towards each other so as to grip said material and form it into a brush head; and sealing said finger elements together so that the portions thereof remote from the brush head form a handle for said brush.
  • a method for producing a single-use, disposable brush comprising the steps of: forming a blank of sheet material with a plurality of radially spaced finger-like elements integrally connected to a common central segment, said finger elements and said central segment being substantially co-planar; placing a pre-formed piece of compressible material onto said central segment of said blank; folding the free ends of said finger elements about said compressible material and pressing said free ends towards each other until said finger elements are substantially perpendicular to said central segment, said finger elements thereby compressing and gripping spaced portions of said compressible material, the uncompressed portions of said compressible material extending radially outwardly from between said finger elements so as to form a brush head; and bonding together the portions of said finger elements remote from the brush head to thereby form a handle for said brush.
  • said compressible material comprises an expandable non-watersoluble foam.
  • said compressible material comprises expandable cellular acetate.
  • said compressible material comprises an expandable polystyrene foam.
