Abstract
Pen-type hazardous material applicators are provided having features useful in applying metal pretreatment material to intricate geometries, such as blind holes, through holes, rivets, crevices, chamfers, counterbores, countersinks and other difficult to access surfaces.
Claims42
An applicator comprising:
- a housing having a chamber, a discharge port, and a valve movable between a closed position in which the discharge port is not in fluid communication with the chamber, and an open position in which the discharge port is in fluid communication with the chamber, and a valve spring configured to bias the valve towards the closed position;
- and
- a wick movably connected to the discharge port and configured to transmit an axial load to the valve to move the valve from the closed position to the open position, the wick comprising a material suitable to receive a fluid from the discharge port and pass the fluid to a location outside the housing;
- wherein the applicator is characterized by:
- means for regulating a volume of flow from the chamber to the wick and/or
- means for positioning the wick at a nonzero angle relative to at least a portion of the housing, optionally wherein the nonzero angle is greater than or equal to 1 degree relative to the longitudinal direction “L” of the housing.

An applicator comprising:
- a housing (1302, 1402, 1502, 1602, 1702, 1802, 2002, 2102, 2202, 2302, 2402) having a chamber (1308, 1408, 1508, 1608, 1708, 1808, 2008, 2108, 2208, 2308, 2408);
- a discharge port (1310, 1410, 1510, 1610, 1710, 1810, 2010, 2110, 2210, 2310, 2410);
- a wick (1312, 1412, 1512, 1612, 1712, 1812, 2012, 2112, 2212, 2312, 2412) connected to the discharge port;
- and
- a valve (1314, 1414, 1514, 1630, 1730, 1830, 2014, 2114, 2214, 2330, 2428, 2430) fluidly connected to the chamber and movable between a closed position in which the valve fluidly disconnects the discharge port from the chamber, and an open position in which the valve fluidly connects the discharge port to the chamber;
- wherein the applicator is characterized by:
- means for regulating a volume of flow from the chamber to the wick.
4 more elements
An applicator comprising:
- a housing (1002, 1202, 2002, 2102, 2202, 2302, 2402, 2502) extending in a longitudinal direction “L” and having a chamber (1008, 1208, 2008, 2108, 2208, 2308, 2408, 2508);
- a discharge port (1010, 1210, 2010, 2110, 2210, 2310, 2410, 2510);
- a wick (1012, 1212, 2012, 2112, 2212, 2312, 2412, 2512) connected to the discharge port;
- and
- a valve (1014, 1214, 2014, 2114, 2214, 2330, 2428, 2430, 2514) fluidly connected to the chamber and movable between a closed position in which the valve fluidly disconnects the discharge port from the chamber, and an open position in which the valve fluidly connects the discharge port to the chamber;
- wherein the applicator is characterized by:
- means for positioning the wick at a nonzero angle relative to at least a portion of the housing, optionally the nonzero angle is greater than or equal to 1 degree relative to the longitudinal direction “L” of the housing.
