Independent Claim 228 words
A disposable applicator for nail polish or other liquid comprising: a frangible ampul containing the liquid; a housing defining a chamber open at one end for housing said ampul, said housing being comprised of a flexible material and an integral section at said one end defining a passage of lesser cross-section than said chamber, said housing and said chamber being of cylindrical shape, said section being of tubular shape and said passage being concentric with said chamber; an applicator secured to said housing at said open end of said chamber, said applicator comprising a plurality of elongated bristles and a tubular retainer having a through bore, said retainer being disposed in said passage with one end of said bristles disposed between the outer surface of said retainer and the inner surface of said tubular section; and a collar separate from said tubular secion and said retainer and disposed about said section in compressing relation thereto so that the inside surface of said passageway is compressed by said collar into sealing engagement with and to securely retain said bristles between said housing section and retainer, whereby said housing may be squeezed for breaking said ampul whereupon said liquid is transmitted to said applicator through said open end of said chamber and liquid flow from said chamber passes serially through said passage, through said bore and directly onto said bristles.
Claim 2
Dependent Claim 228 words
A disposable applicator for nail polish or other liquid comprising: a frangible ampul containing the liquid; a housing defining a chamber open at one end for housing said ampul, said housing being comprised of a flexible material and an integral section at said one end defining a passage of lesser cross-section than said chamber, said housing and said chamber being of cylindrical shape, said section being of tubular shape and said passage being concentric with said chamber; an applicator secured to said housing at said open end of said chamber, said applicator comprising a plurality of elongated bristles and a tubular retainer having a through bore, said retainer being disposed in said passage with one end of said bristles disposed between the outer surface of said retainer and the inner surface of said tubular section; and a collar separate from said tubular secion and said retainer and disposed about said section in compressing relation thereto so that the inside surface of said passageway is compressed by said collar into sealing engagement with and to securely retain said bristles between said housing section and retainer, whereby said housing may be squeezed for breaking said ampul whereupon said liquid is transmitted to said applicator through said open end of said chamber and liquid flow from said chamber passes serially through said passage, through said bore and directly onto said bristles.
