Definitions

  • the present invention relates to a separating mask comprising a nasal part covering the user's nose and a mouth part covering the user's mouth.
  • the document KR 20110007565 A describes a mask formed of two separable parts, a part covering the user's nose and a part covering the user's mouth.
  • the part covering the nose comes to bear under the nose of the user in order to prevent any passage of air between the two parts.
  • the upper portion of the part covering the nose is open and allows the air exhaled through the nose to exit the mask. Nevertheless, this open part also makes it possible to inspire unfiltered air by the mask.
  • the portion covering the nose is made of rigid material and forms a shell whose edge bears against the skin of the user in order to hermetically separate the nasal part from the mouth part.
  • This shell is unpleasant to wear and may, in the long run, cause marks on the skin or even contact allergies.
  • the nasal part has openings covered with filters that allow the inspired air to be filtered.
  • An object of the present invention is to provide a mask in two parts whose manufacture is simple and rapid.
  • Another object of the present invention is to provide a mask which can be easily washed.
  • Another object of the present invention is to provide a mask which correctly filters the inspired air and the expired air, whether the user exhales or inhales through the mouth or through the nose.
  • Another object of the present invention is to provide a mask which is firmly attached to the user's head.
  • Another object of the present invention is to provide a mask which does not interfere with breathing and does not muffle the voice of the user.
  • the present invention relates to a mask comprising a nasal part, covering the user's nose, a mouth part, covering the user's mouth and means for fixing the mask to the user's head.
  • the nasal part and the said mouth part are separated by an elastic separating band
  • the said means for fixing the mask and the said separating band are arranged so as to tension the said separating band when said mask is worn by a user and said separating strip bears against the user's face, under the user's nose and above his upper lip, when said mask is worn.
  • the separation strip is advantageously made of textile material for greater user comfort. It is fixed, in particular sewn on the back of the mask. It can also be slidably mounted in a sheath; in this case, the mask is preferably made of flexible material, textile for example, in order to adapt to the length of the fastening band.
  • the elasticity of the separation band provides increased comfort to the user compared to the edge of the shell of the mask of the prior art.
  • the tensioning of the separation band is done when wearing the mask and can be adjusted, for example by modifying the position of the fastening means on the user's head or by adjusting the fastening means, in particular the length of these.
  • the mask comprises means for bringing the nasal part into contact with the top of the nose and the cheeks of the user. These means make it possible to properly close the nasal part around the user's nose. They prevent, when the mask is an antimicrobial mask, that the inspired air is not filtered by the mask.
  • the nasal part has a three-dimensional shape which can be given to it, for example, by folds formed in the textile material or by whales inserted in the thickness of the material of the nasal part, in particular when it is made of textile. .
  • It can also be a textile that has been shaped beforehand, for example.
  • the means for bringing the nasal part into contact with the top of the nose and the cheeks of the user they comprise a second optionally elastic band, the two ends of which are connected to the said separation band and the said second strip forms a triangle with said strip of separation.
  • the second band is fixed on the free edge of the nasal part.
  • the triangle formed by the second band hugs the user's nose and cheeks, which makes the mask comfortable.
  • the second band is advantageously made of textile material.
  • the second band is elastic, it increases the comfort of the mask and allows adaptation to the morphology of the user's face. It can also, when it is elastic, be arranged so as to be tensioned at the same time as the separating strip. Care must be taken, however, that the tension applied to the second strip is less than the tension applied to the separating strip so that the user's nose is not crushed.
  • said means for bringing into contact further comprise a deformable bar, arranged so as to come into contact with the top of the bridge of the user's nose, said deformable bar can assume a straight configuration, in which it is substantially planar and thus raises said nasal part on either side of the bridge of the user's nose and a folded configuration in which it matches the shape of the user's nose and brings the free edge of said nasal part with the surface of the user's face, when said mask is worn and/or said nasal part comprises deformable vertical stays capable of giving said nasal part a three-dimensional shape.
  • the top of the nose corresponds to the arch of the nose or any portion of the nose near the root of the nose, or even the root of the nose itself.
  • the deformable bar can be removable from the mask or integrated into the latter. It allows good adaptation to the shape of the user's face; in particular, it allows the second band to fit the user's face well. It is on this bar that the traction of the fastening means will be exerted (if there is traction). Its position makes the tension more bearable because it is a bony area.
  • the strip also makes it possible, in its folded configuration, to form ventilation shafts on either side of the nose and opening out towards the eyes of the user. These chimneys facilitate the breathing of the user as explained later.
  • the deformable vertical whales make it possible to adjust the nasal part to the user's face, in particular in depth, according to the length of the user's nose.
  • the deformable stays allow the nasal part to form a pocket in which it is easy to breathe and which does not crush the user's nose.
  • the stays extend vertically over all or part of the nasal part, between the fastening strip and the second strip or the free upper edge of the mask, in the absence of a second strip.
  • they are arranged on either side of the middle part of the nasal part.
  • the mouth part extends under the user's chin and has openings where its free edge is remote from the user's face and/or neck.
  • the mouth part thus makes it possible to protect the mouth of the user well and avoids sputters. Since it does not come into contact with the skin of the user, the latter does not have a feeling of confinement.
  • a relatively rigid and heavy textile material makes it possible to obtain a fall of the mouth part which keeps it away from the skin of the user.
  • the free edge of said mouthpiece is at least partially tightened by an element so as to match the shape of the contour of the user's face without coming into contact with the latter.
  • an element may be a possibly elastic band or a thread which allows the free edge to be pleated.
  • the mouth part thus forms a pocket surrounding the lower face of the user.
  • the fixing means comprise an elastically deformable fixing strip, at least one end of which comprises a first fixing element capable of cooperating with a second fixing element arranged in such a way that said fixing strip forms a loop capable of surrounding the user's head. In this case, it is possible to open the loop formed by the fixing strip.
  • the fixing means may comprise four fixing elements; two fixing elements mounted on said mask and two fixing elements capable of cooperating with the two aforementioned fixing elements and mounted on the ends of the fixing strip. This gives a mask suitable for left-handers and right-handers. The mask itself can thus be changed independently of the fastening band.
  • said fastening means further comprise an additional fastening strip fixed to said nasal part and which forms an arch passing above the ears of the user or by the top of the head of the user, when said mask is worn.
  • This strip makes it possible to better fix the mask, making it suitable for certain uses during physical activities of the user (walking, gymnastics, running, etc.).
  • this additional fastening band forming an arch is mounted on said nasal part by fastening means making it removable.
  • the mask can thus be changed without any obligation to change the fastening means.
  • said fastening means further comprise an auxiliary band, the two ends of which are fixed to said additional fastening band and which passes behind the user's head and above the user's ears, when said mask is worn.
  • the mask includes means for adjusting the length of said fastening strip. It is thus easy to adapt to the user and the adjustment of the tension of the separation strip is easy.
  • Fastening elements are not limited according to the invention.
  • Said first fastening element and said second fastening element can be selected from the group consisting of a hook, a loop or ring, a surface covered with loops or hooks. They are chosen so that they can cooperate.
  • the constituent material or materials of the mask are not limited according to the invention. It can be soft, sheet-like materials. This sheet can be plastic or textile (fabric, non-woven or knit). The mask can thus comprise a transparent plastic mouth part and a textile nose part.
  • said nasal part and/or said mouth part comprise or consist of a textile material whose pores are sized so as to filter out microbes.
  • a mask entirely made of textile material is then obtained which is simple to manufacture and can be washed.
  • the ends of the second band can be attached directly or indirectly (in particular sewn) to the ends of the separating band so as to tension the second band.
  • the ends of the separation strip can be fixed directly or not (sewn when the mask is made of textile) on the ends of the fastening band.
  • the separation strip and the fixing strip can also form a single strip.
  • the textile forming the nasal part may be different from that forming the mouth part.
  • the textile has a certain density/rigidity in order to form pleats sufficiently in relief to give the mask or part of the mask a three-dimensional shape even when it is not worn. It also allows a fall which moves the mouth part and the nasal part away from the face of the user, only the separating strip resting on the latter.
  • textile material denote, within the meaning of the invention, a material which comprises one or more layers of a material or of several materials chosen independently of one another from among fabrics, knits and nonwovens.
  • microbe refers in the sense of the invention to bacteria, viruses.
  • connection designates the presence of a direct or indirect mechanical connection between two elements.
  • the elements can be fixed one on the other, one to the other or both fixed on an intermediate element.
  • the mask of the invention comprises a nasal part 11 and a mouth part 13, located under the nasal part 11.
  • the two parts 11 and 13 are formed from the same piece of textile material having the ability to filter out microbes.
  • the separating strip 3 is sewn on the reverse side of the textile piece which corresponds to the reverse side of the mask, which comes into contact with the face of the user.
  • the separation strip can also be placed in a sheath in which it can slide.
  • the nasal part 11 has a three-dimensional shape and forms a sort of pocket in which the user's nose fits easily and comfortably.
  • This three-dimensional shape is conferred, for example, by folds formed in the textile material, one end of the folds being sewn, one obtains the creation of a volume.
  • the textile used has a certain rigidity and a certain weight so as to be able to maintain its shape.
  • the two ends of the separation strip 3 are each sewn onto one end of the fastening strip 5.
  • the second elastic strip 7 comprises two ends each sewn onto one end of the separation strip 3.
  • the second elastic strip 7 comprises at level with the top of the user's nose, a deformable bar 71, for example metallic, which can be deformed so as to match the shape of the edge and of the user's nose.
  • the bar 71 thus matches the shape of the nose and extends on each side of the user's nose. When the bar 71 is not deformed but left straight, it raises the second elastic band 7 on either side of the nose, forming openings oriented towards the user's eyes.
  • openings facilitate the breathing of the user and, because of their position and their orientation, prevent the user from exhaling towards another person located in front of him.
  • the position and orientation of these openings ensure that the mask avoids any contamination from a third party.
  • microbes exhaled by a person located face to face with the user have a low risk of being inhaled by the user through the aforementioned openings.
  • the mouth part 13 extends from the jawbones to an area located under the chin of the user.
  • the lower free edge 131 of the mouth part 13 falls under the effect of the weight of the textile material but remains at a distance from the skin of the user due to the rigidity of the textile material used.
  • the free edge 131 is equipped with an elastic band which tightens the free edge 131 so that the latter conforms to the shape of the contour of the user's face.
  • the mouth portion 13 thus forms, at the level of the seam with the band 133, small gathers which give a three-dimensional structure to the mouth portion 13; the mouth portion 13 forms a bulging pocket that surrounds the lower face of the user.
  • the separation strip 3 passes under the nose and above the upper lip of the user.
  • the second strip 7 forms a triangle with the separation strip 3.
  • the top of the triangle formed by the second strip 7 comes on the top of the bridge of the user's nose and is held in place by the deformable bar 71.
  • the fixing strip 5 comprises fixing means 9 which, in the embodiment shown, comprise a hook which cooperates with a loop or ring.
  • Other fastening means can also be used.
  • the fastening band 5 is equipped with means for adjusting its length 53. In the present case, it is a double ring; the end of the fixing band 5 is fixed on the separation of the two rings and adjusting the position of the adjusting means 53 on the band 5, it is possible to fold a portion of the elastic band on itself by there even vary the length of the usable portion of the fastening strip 5.
  • These length adjustment means are commonly used to adjust the length of bra straps, for example.
  • the attachment means also comprise additional attachment strip 55, which forms an arch passing through the top of the user's skull.
  • the two ends of this additional strip 55 are attached to the nasal part 11, close to the ears of the user, when the mask is worn. Fixing can be implemented by strips provided with hooks or loops capable of cooperating together (Velcro ® type strip).
  • the mask also includes an auxiliary band 57, the two ends of which are fixed to the band additional 55. The axillary band goes over the wearer's ears and on the back of their head.
  • the additional strip 55 and the auxiliary strip 57 improve the hold of the mask on the user's head.
  • the latter can move freely without fear of moving the mask of the invention.
  • This type of mask can be used, for example, during physical activities.
  • the two bands 55 and 57 are, for example, inelastic textile.
  • the use of the mask will now be described with reference to the Fig. 1 and 2 .
  • the user first separates the fasteners. He positions the bar 71 on the arch of his nose and possibly deforms it so that it matches the shape of this zone of his nose. He then places the separation strip 3 between his nose and his upper lip. He then assembles the fastening elements so as to tension the separation strip 3 and the fastening strip 5. This tensioning also causes the tensioning of the second strip 7 which thus presses the edge of the nasal part 11 against the user's face. The tension on the bridge of the nose remains light.
  • the user can adjust the tension of the separation strip 3 by acting on the length of the fastening strip 5 and/or by adjusting the position of the fastening elements 9.
  • the fastening strip 5 passes under the user's ears and surrounds the back of their head.
  • the mouth part 13 does not form a closed enclosure on the user's mouth facilitates exhalation through the mouth and does not muffle the voice.
  • the user does not have the feeling of having the lower face locked in.
  • the heat generated by exhalation is also quickly evacuated to the outside making the mask comfortable to wear.
  • the mouth part 13 is long enough to avoid sputters and the transmission of bacteria and viruses by air due to the filtering effect of the textile material.
  • the nose is well covered by the nasal part 11 and the second strip 7 makes it possible to seal the nasal part 11: the user cannot, in fact, inhale air which has not been filtered by the textile material of the mask. The mask thus prevents the entry of microbes into the nostrils of the user.
  • the nasal part comprises two vertical whales located on either side of the nose and which join the separation strip 3 and the second strip 7 or the upper edge of the mask when the latter does not include a second strip 7. These whales are deformable and make it possible to give a three-dimensional shape to the nasal part, which thus forms a pocket in which it is easy to breathe.
