Abstract: An applicator (10) to apply a treatment to hair, such as a die. The applicator (10) has a stem (11) with a passage (13) that receives the liquid to be applied to the hair. Fixed to the stem (11) is an applicator portion (21) having apertures (24) in the form of slits into which the hair enters for the liquid to be applied thereto.

Abstract: An applicator (10) to apply liquid (32) to hair. The liquid may be a dye or other hair treatment liquid. The applicator (10) has a handle (11) that is hollow so as to provide a chamber (12) to store the liquid (32). Fixed to the handle (11) is a stem (16) having a passage (20) that receives the liquid, while there is fixed to the stem (16) an applicator portion (23) having apertures (26) communicating with the passage (20) so the liquid may be delivered by the applicator (10).

Abstract: A key (21) for a keyboard or keypad, the key (21) having an upper finger engaged surface (2) defining a generally top edge portion (3) remote from the user, a generally bottom edge portion (4) adjacent to the user, a generally left edge portion (5) and a generally right edge portion (6), the key (21) further having a ridge (22) adjacent to the top edge portion (3), the bottom edge portion (4), the left edge portion (5) and/or the right edge portion (6).

Abstract: Key (21) for a keyboard or keypad, having an upper finger engaging surface (2) of generally square or rectangular configurations so as to have a top edge portion (3) remote from a user, a bottom edge portion (4) adjacent the user, a left edge portion (5) and a right edge portion (6), the key further having a ridge (22) adjacent the top edge portion (3) or the bottom edge portion (4) and extending longitudinally generally parallel thereto, and a ridge on the left or right portion (5, 6). The keys may be arranged on a keyboard or keypad to provide tactile identification of rows or blocks of keys.

Abstract: The present invention relates to a toothbrush which exhibits superior interproximal and gingival margin cleaning. The toothbrush includes an elongated handle member connected to a toothbrush head member. The head is divided into two regions. A "toe" region is defined as the part of the head which is furthest from the handle and a "heel" region is the portion of the head which is closest to the handle. A multiplicity of bristles extend from the heel region of the head; the distal ends of these bristles form a longitudinally aligned concave shape when viewed on end.
