Claim:
A pretreatment cup ( 10 ) comprising: a base comprising an exterior base surface ( 50 ); a wall comprising an exterior wall surface ( 60 ); and an opening ( 40 ) circumscribed by a rim ( 170 ), wherein the opening is at least partially opposite the base; wherein the exterior base surface ( 50 ) is connected to the exterior wall surface ( 60 ) at an exterior periphery ( 70 ); characterized in that: a surface selected from the group consisting of: the exterior base surface ( 50 ), the exterior wall surface ( 60 ), and mixtures thereof, comprises a spreading region ( 80 ), wherein the spreading region ( 80 ) comprises one or more spreading protrusions ( 90 ), wherein the spreading protrusions ( 90 ) are arranged in a pattern selected from the group consisting of: radial, concentric, spiral, or mixtures thereof; wherein the spreading region ( 80 ) has a curvature such and a centre of mass, such that when the pretreatment cup is positioned with the centre of mass of the spreading region ( 80 ) on a non-deformable surface, the pretreatment cup can be tilted a maximum of about 45° before the spreading region is no longer in contact with the non-deformable surface.
