Abstract
An oral care implement has an overall length extension extending between a proximal end and a distal end, the distal end being opposite the proximal end. The oral care implement comprises a head at the proximal end and a handle, the handle being at least partially made from a material having a density being higher than the density of the material of the head. The oral care implement has a center of gravity located at a distance measured from the distal end, and the ratio of said distance to the overall length extension of the oral care implement is from about 0.30 to about 0.45, preferably from about 0.35 to about 0.42, further preferably from about 0.38 to about 0.41.
Claims16
An oral care implement having an overall length extension extending between a proximal end and a distal end opposite to the proximal end, the oral care implement comprising a head made of a non-magnetic and/or non-ferromagnetic material and disposed at the proximal end and a handle at least partially made from a material having a density that is higher than the density of the material of the head, the oral care implement having a center of gravity located at a distance measured from the distal end, wherein a ratio of said distance to the overall length extension of the oral care implement is from about 0.30 to about 0.45, wherein the material of the handle comprises a magnetic and/or ferromagnetic material selected from a group consisting of amorphous thermoplastic resin, iron oxide, aluminum oxide, boron nitride, aluminum silicate, and any combination thereof, wherein the magnetic and/or ferromagnetic material of the handle comprises from about 13 weight percent to about 30 weight percent of an amorphous thermoplastic resin;
- from about 3 weight percent to about 25 weight percent of aluminum oxide, boron nitride, or aluminum silicate;
- and from about 45 weight percent to about 67 weight percent of iron oxide.
An oral care implement comprising:
- a head made of a non-magnetic and/or non-ferromagnetic material and disposed at the proximal end;
- and
- a handle at least partially made from a magnetic and/or ferromagnetic material selected from a group consisting of from about 13 weight percent to about 30 weight percent of an amorphous thermoplastic resin, from about 3 weight percent to about 25 weight percent of aluminum oxide, boron nitride, or aluminum silicate, and from about 45 weight percent to about 67 weight percent of iron oxide.
An oral care implement having a proximal end, a distal end opposite to the proximal end, and a length extension extending between the proximal end and the distal end, the oral care implement comprising:
- a head made of a non-magnetic and/or non-ferromagnetic material and disposed at the proximal end;
- and a handle at least partially made from a magnetic and/or ferromagnetic material selected from a group consisting of from about 13 weight percent to about 30 weight percent of an amorphous thermoplastic resin, from about 3 weight percent to about 25 weight percent of aluminum oxide, boron nitride, or aluminum silicate, and from about 45 weight percent to about 67 weight percent of iron oxide,
- wherein the oral care implement has a center of gravity located at a distance measured from the distal end, and wherein a ratio of said distance to the overall length extension of the oral care implement is from about 0.30 to about 0.45.
