The present application provides porous sintered multiple element applicators and methods of making and using these nibs. Porous nibs are made of sintered plastic particles. These nibs can be used to apply liquids containing high solids or pigments to surfaces such as metal, paper, skin, hair, tissues or wounds, liquid applicator devices, medical devices, writing implements or cosmetic applications. Used with the In a first embodiment, the nib includes a shank (12), a nub (14) and a head (16), wherein the shank contacts a first end of the nub and the head is a second end of the nub Contact the part, where the average hole size of the shank is larger than the average hole size of the nubs, and the average hole size of the nubs is larger than the average hole size of the head. In a second embodiment, the nib comprises a shank (12) and a head (66), wherein the shank has a first end in contact with the liquid in the reservoir and a second end in contact with the head And the head has a body (63) and a tip (64), wherein the mean hole size at the first end of the shank is larger than the mean hole size at the second end of the shank The average hole size of the head body is larger than the average hole size of the head chip. |
