DEFINITION

Classification: 401/196

(under the class definition) Implement comprising a tool* whose work-engaging portion is formed of a previous layer(s) or mass having interstices of substantially capillary size through which the coating material must pass from one surface thereof to another and hence to the work surface.

(1) Note. The supply means* may be structure defining a pocket within the tool, the interior wall of the pocket being considered one surface through which the material is required to flow. However, an implement comprising a plurality of layers, one or more of which is coated or impregnated with coating material but has no additional supply-means will not be considered subject matter for this class but will be placed in the Brushing, Scribbing, and General Cleaning and Coating Apparatus classes. See the search notes below.

(2) Note. The previous layer(s) may be of porous textile fabric having a pile or nap, but not of a fabric which has elongated porous strands extending therefrom such as would be considered to be filamentary elements of a mop. See Search This Class, Subclass note below.

(3) Note. A tool having a hole therethrough through which the material is intended to pass, even though it may be of porous material, is presumed to be an apertured tool. A patent for an implement with such a tool will be placed in elsewhere when there is nothing in the disclosure describing the passage of material through the tool to its work-engaging portion as occurring in any other way than through such holes. See Search this Class, Subclass notes below.

23+, for an implement having diverse tools, one of which is porous.

261+, for an implement in which: (a) the work-engaging portion of the tool includes a nonporous fabric having a pile or nap of ordinary length; or (b) the tool is perforated for passage of all the material which penetrates to the work-engaging surface (see particularly, subclasses 265+); and see (3) Note, above.

268+, for an implement in which the work-engaging portion of the tool includes a fabric having elongated flexible strands extending from a porous backing; and see (2) Note, above.

15, Brushing, Scrubbing, and General Cleaning,

104.93+, for a tool of porous material coated or impregnated with supply material, but not including additional supply-means; and subclasses 118 for a machine-attachable porous pad tool combined with means for supplying coating material to the tool.

118, Coating Apparatus,

264+, for a coating apparatus including a porous tool which is static, requiring that the work be applied thereto.

132, Toilet,

218, and 320 for a porous cosmetic applier having a shape peculiarly adapted to put a coating on a part of the human body in a definite shape or pattern (e.g., a bow-shaped lip rough applicator).
