Abstract
The invention relates to a semi-open mask, transparent or matte, reusable, which protects against the spread of germs, and especially viruses, which can be transmitted through saliva drops and nasal secretions (Flügge drops). The semi-open mask consists of an upper naso-pyramidal part (1) that covers the nasal pyramid and the nose, and the mask’s body (2), which has a semi-open lower part (3), allowing the free passage of breathed air (4). The anterior face of the mask’s body (2) has a discreetly convex surface inwards (5), so that the exhaled air moves exclusively downwards due to the Coanda effect. In order to seal the upper region of the mask, the upper naso-pyramidal part (1) and the mask’s body (2) are provided with a moulded edge to contact the face of the mask‘s wearer (6).
