<p>The invention concerns a filter container for an absorption filter (8) and a particle filter (7), said container being adapted to be connected to a protective mask. The filter container is characterised in that it comprises a cup-shaped casing (1) which has in its bottom (2) an inlet (3) for inhalation air, and a cover (4) closing said casing (1), said cover having an outlet (5) for inhalation air and being connectible to the protective mask, said particle filter (7) being arranged at the bottom (2) of the cup-shaped casing (1), and said absorption filter (8) being arranged between the particle filter and the cover (4) closing the casing; that the particle filter (7) is sealed to the casing (1) by means of glue (9) applied to the inner side of the casing; that the portion (14) of the cup-shaped casing (1) containing the particle filter (7) is essentially cylindrical and has a diameter smaller than the remaining cylindrical casing portion (13) containing the absorption filter; that the bottom (2) of the casing (1) and the cover (4) are slightly conically bulging outwardly towards the air inlet (3) and the air outlet (5), respectively; and that closely lying, radially extending stiffening ribs (15, 16) are arranged on the slightly conical portions of the bottom (2) and the cover (4), respectively, and have their tops (17) facing inwardly towards the container lying in radial planes.</p> |
