Filler tube for liquid containers

摘要

The present invention relates to filler tubes and, more particularly, to fuel filler tubes and methods of attaching them to automobile fuel tanks. The fuel filler tube of the present invention includes an inlet tube, a retainer member, sealing means and a fuel tank having a downwardly extending diameter portion. The retainer is disposed over the downwardly extending diameter portion and adhered to the tank. The inlet tube is then inserted into the fuel tank aperture until the inlet tubes annular flange engages the fuel tank's annular lip. A crimping tool is then inserted through the axial bore of the inlet tube and a plurality of bearings contained on the crimping tool are forced radially outwardly to thereby crimp the inlet tube and downwardly extending diameter portion together. The retainer member includes a plurality of recessed areas for hosting the expanded inlet tube and tank portions.
