Title
(EN) DISPOSABLE, RECYCLABLE PROTECTIVE RESPIRATORY MASK
(FR) MASQUE DE PROTECTION RESPIRATOIRE À USAGE UNIQUE RECYCLABLE
Abstract
(EN)
The invention relates to a disposable respiratory mask (1) in the form of a shell, comprising a body (2) and straps (3, 4). The body (2) is formed by at least one, and preferably two layers (15, 16, 17), including at least one layer of filter material (15). In addition, the body includes a nose region (11) provided with a projection (14). The straps (3, 4) are elastic and are secured to the body (2) of the mask (1) without any additional material, preferably by means of welding. The mask (1) is characterised in that all of the layers (15,16,17) of material forming the body (2) are non-woven layers of a single thermoplastic polymer material and the straps (3, 4) are formed by one or more components made from thermoplastic elastomer or polymer elastomer materials that can form a mixture with the polymer forming the non-woven layers.
