Abstract
The invention relates to a sealing lip device for a respiratory mask, to a respiratory mask per se and to a method and mould for producing the same. According to the invention, the respiratory mask has an orifice () for receiving at least the nose tip of the mask wearer and a sealing lip () consisting of an elastomeric material, which surrounds the orifice and crosses the bridge of the nose. Said sealing lip has a supporting zone which lies against the face of a mask wearer. The elastic pliability of the sealing lip () is such that the sealing lip zone (a) which seals the area around the bridge of the nose has a greater pliability than the sealing lip zone (b, b, c) which lies adjacent to the nostrils and/or the upper lip of the mask wearer, when the mask is applied to the face of the latter. From a production method viewpoint, the synthetic material is introduced in two separate injection-moulding steps, a support structure () with thick walls being preferably configured in the first step.
