Claim Text:
1. A hand-held work implement comprising an internal combustion engine, an air filter, wherein the air filter comprises a filter element which is connected in a fixed manner on its end sides to end plates, wherein the filter element is cylindrical, wherein the filter element and the end plates create a separation between a dirty side and a pure side of the air filter, wherein the pure side of the air filter is connected via a duct to the internal combustion engine, and wherein a first end plate is configured as an air filter bottom, and an intermediate flange, wherein the intermediate flange is arranged between the air filter and the internal combustion engine, wherein the bottom of the intermediate flange is arranged opposite the air filter bottom, wherein the air filter bottom and the intermediate flange bound an interior space, wherein the interior space comprises a portion of the duct, wherein a portion of the duct in the interior space is bounded by at least one boundary wall which protrudes into the interior space transversely with respect to the air filter bottom, wherein the boundary wall is formed integrally on the intermediate flange and/or on the air filter bottom, wherein the boundary wall bridges the spacing between the air filter bottom and the bottom of the intermediate flange, wherein at least two seals are molded on the air filter bottom, wherein the two seals bear against the intermediate flange and seal the interior space, wherein a first seal bears against the intermediate flange in a transverse direction with respect to the longitudinal center axis of the filter element and seals in the radial direction, wherein a second seal bears against the intermediate flange in the direction of the longitudinal center axis and seals in the direction of the longitudinal center axis, wherein the first seal and second seal are designed as sealing lips, wherein the air filter bottom is composed of a dimensionally stable plastic, wherein the first seal and the second seal are composed of an elastic material, wherein the first seal and second seal are connected and are injection molded on the air filter bottom.
