Abstract
A toothbrush is described whose handle has a special arrangement. The handle includes an elongated handle arm formed of a plastic having a Shore Hardness value of at least 90. A pressure pad is attached to the arm and formed of an elastomer having a Shore Hardness value no higher than 80. Advantageously, the elongated handle arm has a recess in an area adjacent to connection with the brushhead. The pressure pad is arranged within that recess. At least one radial anti-slip structure, especially a semi-ring shape, protrudes from and circumscribes bottom and lateral surfaces of the arm.

- an elongated arm traversing a full length of said handle, said arm having a top, bottom and two lateral surfaces with the two lateral surfaces being disposed between and on opposite sides of said top and bottom surfaces, said arm being formed of a plastic having a Shore Hardness value of at least 90;
- a recess formed within said top surface of said arm in an area adjacent to connection with said brushhead;
- a pressure pad arranged within said recess of said arm as an elongate body along said top surface and formed of an elastomer having a Shore Hardness value no higher than 80;
- and
- at least one anti-roll structure protruding from and circumscribing said bottom and lateral surfaces of said arm, said at least one anti-roll structure being positioned to flank and extend below said pressure pad.
A toothbrush comprising:
- a brushhead comprising a base and bristle tufts projecting from said base, said brushhead having a first and second end;
- and
- a handle connected to said second end of said brushhead, said handle comprising:
- an elongated arm formed of a plastic traversing the full length of said handle, said arm having a top, bottom and two lateral outer surfaces with the two lateral surfaces being disposed between and on opposite sides of said top and bottom surfaces;
- a recess formed within said top surface of said arm in an area adjacent to connection with said brushhead;
- a pressure pad arranged within said recess of said arm as an elongate body along said top surface of said arm;
