Interdental toothbrush

An interdental handle having a molded-in-place twisted wire brush comprising:

• a handle having a first portion at one end with a flexing and substantially resilient capability, and a second portion at an opposite end which is relatively rigid;
• and
• a brush with a twisted wire stem having a distal end embedded in at least said first portion of said handle and a proximal end projecting from said first portion of the handle;
• said first portion having at least one circumferentially extending groove adjacent the distal end of the twisted wire stem for preventing undesirable protrusion of the twisted wire stem from the first portion during manufacture of said interdental handle, said at least one circumferentially extending groove having a diameter which is substantially larger than the diameter of the twisted wire stem, wherein said first portion is generally tapered and includes a tip end, and a first and second truncated section each having a lower plane and an upper plane, the lower plane of said first truncated section being integral with and adjacent said second portion, the lower plane of said second truncated section being integral with and adjacent said upper plane of said first truncated section, and said tip end being integral with and adjacent said upper plane of said second truncated section, said at least one circumferentially extending groove being substantially located on said second truncated section of said first portion.

• and
• a brush with a twisted wire stem having a distal end embedded in at least said first portion of said handle and a proximal end projecting from said first portion of the handle;
• said first portion including at least two integrally formed and differently shaped truncated sections, said first portion having a circumferentially extending ripple neck located on at least one of said truncated sections adjacent the distal end of the twisted wire stem for preventing protrusion of the twisted wire stem from the first portion during manufacture of said interdental handle, said tipple neck being substantially tapered.

An interdental handle having a molded-in-place twisted wire brush comprising:

• a handle with a central longitudinal axis, said handle having a first portion of reduced cross-section at one end with a flexing and substantially resilient capability, and a second portion of a larger cross-section at an opposite end which is relatively rigid;
• and
• a brush with a twisted wire stem having a distal end embedded in at least said first portion of said handle and a proximal end projecting from said first portion of the handle;
• said first portion having a plurality of circumferentially extending grooves adjacent the distal end of the twisted wire stem for preventing undesirable protrusion of the twisted wire stem from the first portion during manufacture of said interdental handle, each of said grooves having a corresponding inner surface, said twisted wire stem being juxtaposed against one side of said inner surface and being spaced from the opposite side of said inner surface, said sides of said inner surfaces being on diametrically opposite sides of said central longitudinal axis of said handle.
