Abstract
Abstract A tooth cleaner comprises an elongate plastic body (1) and a brush portion (2) connected with the body and consisting of a plastic fabric or net which forms bristles (3) projecting from the body in the transverse direction. A method for manufacturing the tooth cleaner comprises preparing an injection mould suited for injection moulding or like moulding of an elongate plastic body, inserting between the splits of the mould a strip of a plastic fabric or net having a larger width than the moulding cavity, closing the mould, and injecting plastic in the mould to form the body which is thermally bonded to the strip.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
115 words
A tooth cleaner, characterized in that it comprises an elongate thermoplastic body which is substantially triangular in cross-section, and a brush portion (2) connected with said body which are adapted to fit in and clean the space between two teeth, said brush portion consisting of a strip of a thermoplastic material, said strip of thermoplastic material being fused to one side surface of said triangular body portion and extending at least slightly beyond said body in opposite transverse directions thereof, said strip also being coplanar with the side surface to which it is fused, said strip forming bristles along each oppositely extending portion, and further wherein said strip and bristles extend lengthwise along said body.
Claim 2
Dependent Claim
115 words
A tooth cleaner, characterized in that it comprises an elongate thermoplastic body which is substantially triangular in cross-section, and a brush portion (2) connected with said body which are adapted to fit in and clean the space between two teeth, said brush portion consisting of a strip of a thermoplastic material, said strip of thermoplastic material being fused to one side surface of said triangular body portion and extending at least slightly beyond said body in opposite transverse directions thereof, said strip also being coplanar with the side surface to which it is fused, said strip forming bristles along each oppositely extending portion, and further wherein said strip and bristles extend lengthwise along said body.
Claim 3
Dependent Claim
30 words
A tooth cleaner as claimed in claim 1, characterized in that the bristles of the brush portion have been provided by punching or cutting a strip of fabric or net.
Claim 4
Dependent Claim
22 words
A tooth cleaner as claimed in claim 1, characterized in that the bristles of the brush portion are formed of non-woven warp.
Claim 5
Dependent Claim
28 words
A tooth cleaner as claimed in claim 1, characterized in that said body (1) and said brush portion (2) consist of different thermoplastic materials which are thermally interconnected.
Claim 6
Dependent Claim
94 words
A method for manufacturing the tooth cleaner as claimed in claim 1, characterized by preparing an injection mould which is suitable for injection molding or like molding of an elongate plastic body, inserting between the splits of said mold a strip of a plastic fabric or net so as to over the part of the body cavity, which is to form the tooth cleaner portion carrying the bristles, closing the mould, and injecting plastic into the cavity to form said body which is thermally bonded along one side of said body to said strip.
