Por lo tanto, la presente invención se circunscribe dentro del ámbito de las mascarillas higiénicas reutilizables. Therefore, the present invention falls within the scope of reusable hygienic masks.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Las mascarillas son unos dispositivos diseñados para proteger al portador de la inhalación de bacterias aerotransportadas, dichas bacterias y células eucahotas son el principal vector de transmisión de microorganismos, como virus, así como gotículas de agua, y dicha mascarilla ofrece una protección real y altamente eficaz tanto contra las bacterias así como contra las gotículas, gracias a su capacidad hidrófuga. Dichas mascarillas protegen tanto al portador como al interlocutor, disminuyendo significativamente la probabilidad de contraer enfermedades debido a m ¡coorganismos que fluyen por los aerosoles de cualquier espacio. Masks are devices designed to protect the wearer from inhaling airborne bacteria, said bacteria and eucahota cells are the main vector of transmission of microorganisms, such as viruses, as well as water droplets, and said mask offers real and highly effective protection. both against bacteria and against droplets, thanks to its water-repellent capacity. These masks protect both the wearer and the interlocutor, significantly reducing the probability of contracting diseases due to microorganisms that flow through the aerosols of any space.
En general las mascarillas higiénicas son de un solo uso y aquellas reutilizables de tela presentan diferentes problemáticas, por un lado carecen de la suficiente rigidez estructural, carecen de un correcto sellado facial y en la gran mayoría de los casos no presentan la suficiente filtración bacteriana del 90% que garantiza un alto nivel de seguridad ante agentes patógenos, además, pasados vahos lavados, éstas no ofrecen ni la suavidad, ni el confort requeridos para el contacto con la piel . Estas mascarillas tampoco poseen una capacidad hifrófuga que evite el paso de los aerosoles generados al toser, hablar o respirar, siendo estás gotículas de agua un vector importante de transmisión de microorganismos. In general, hygienic masks are for single use and reusable fabric masks present different problems, on the one hand they lack sufficient rigidity structural, they lack a correct facial seal and in the vast majority of cases they do not present the sufficient bacterial filtration of 90% that guarantees a high level of safety against pathogenic agents, in addition, after steam washing, they do not offer either the softness, or the comfort required for contact with the skin. These masks also do not have a water-repellent capacity that prevents the passage of aerosols generated by coughing, speaking or breathing, since these water droplets are an important vector for the transmission of microorganisms.
Además, las mascarillas higiénicas de tela carecen de un diseño para asegurar un sellado facial equivalente al de las mascarillas FFP2. In addition, hygienic cloth masks lack a design to ensure a facial seal equivalent to that of FFP2 masks.
Por lo tanto, es objeto de la presente invención desarrollar una mascarilla que cuenta con una suficiente rigidez estructural, con un sellado facial altamente eficiente, con una elevada capacidad de filtración bacteriana (99,9%), y todo esto ofreciendo una agradable sensación de suavidad y confort en el contacto con la piel facial, además de contar con una elevada capacidad hidrófuga, desarrollando una mascarilla como la que a continuación se describe y queda recogida en su esencialidad en la reivindicación primera. Therefore, the object of the present invention is to develop a mask that has sufficient structural rigidity, with a highly efficient facial seal, with a high bacterial filtration capacity (99.9%), and all of this offering a pleasant sensation of softness and comfort in contact with the facial skin, in addition to having a high water-repellent capacity, developing a mask such as the one described below and is included in its essentiality in the first claim.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
Es objeto de la presente invención una mascarilla higiénica reutilizable que comprende tres capas de tejido no tejido, es decir, de un tejido proyectado, donde: la primera capa o capa exterior es la encargada de dotar de rigidez estructural a la mascarilla, está realizada en polipropileno (spunbound) con un gramaje de 80 g/m2 y fabricada mediante un proceso de unión por hilatura que es un proceso el cual combina las fibras con formación de la banda colocando el dispositivo de unión en línea con el giro la segunda capa o capa intermedia es la encargada de dotar a la mascarilla de una elevada filtración bacteriana del 99,9%. Dicha capa está realizada en polipropileno con un gramaje de 25 g/m2 y está fabricada mediante un proceso de soplado en fusión. Dicha capa consigue su elevadísimo porcentaje de filtración bacteriana gracias a que es capaz de retener una carga electroestática en su interior, se trata del material (Meltblown). la tercera capa o capa interior es la encargada de proporcionar suavidad y confort en el contacto con la piel así como la transpiración, está realizada en polipropileno (Spundbound) con un gramaje de 25g/m2 y fabricada mediante un proceso de unión por hilatura. The object of the present invention is a reusable hygienic mask that comprises three layers of non-woven fabric, that is, of a projected fabric, where: the first layer or outer layer is responsible for providing structural rigidity to the mask, it is made of polypropylene (spunbound) with a grammage of 80 g/m2 and manufactured by means of a spunbonding process, which is a process which combines the fibers with the formation of the band by placing the joining device in line with the twist of the second layer or layer intermedia is responsible for providing the mask with a high bacterial filtration rate of 99.9%. Said layer is made of polypropylene with a grammage of 25 g/m2 and is manufactured by means of a melt blown process. This layer achieves its very high percentage of bacterial filtration thanks to the fact that it is capable of retaining a electrostatic charge inside, it is the material (Meltblown). the third layer or inner layer is responsible for providing softness and comfort in contact with the skin as well as perspiration, it is made of polypropylene (Spundbound) with a grammage of 25g/m2 and manufactured through a spun bonding process.
Entre la primera capa o capa exterior y la segunda capa o capa intermedia se dispone una banda deformable para el clipado en la nariz, de manera que se consigue una mejor adaptabilidad y ajuste al rostro, dejando menos espacios vacíos para el paso de posible aerosoles. Between the first layer or outer layer and the second layer or intermediate layer there is a deformable band for clipping on the nose, so that better adaptability and adjustment to the face is achieved, leaving fewer empty spaces for the passage of possible aerosols.
Las capas una vez dispuestas la una sobre la otra e interpuesta la banda para el clipado de la nariz se unen mediante sellado con ultrasonidos con un primer rodillo que marca la forma de la mascarilla, posteriormente se sueldan las gomas de sujeción en las orejas también mediante sellado con ultrasonidos. The layers, once arranged one on top of the other and the band for clipping the nose interposed, are joined by sealing with ultrasound with a first roller that marks the shape of the mask, then the fastening rubber bands are welded on the ears also by means of ultrasonic sealing.
La unión de las diferentes capas de la mascarilla tiene lugar tanto perimetralmente como en la zona interior, definiéndose unas bandas de unión interior con objeto de dotar de suficiente estabilidad estructural y posicional a las diferentes capas. The union of the different layers of the mask takes place both on the perimeter and in the interior area, defining interior union bands in order to provide sufficient structural and positional stability to the different layers.
Otra característica de la mascarilla objeto de la invención es su sellado facial. La presente mascarilla tiene exactamente el mismo formato que una mascarilla FFP2, ya que para su fabricación se utilizan líneas de producción de mascarillas FFP2, habiendo pasado por tanto las pruebas de Fuga de Aire hacia el Interior (T.I.L.S) y de comodidad de sujeción con respecto a la movilidad. Una mascarilla higiénica normal no cumple con dichos requisitos, ya que no se le realizan dichas pruebas, y por tanto los aerosoles a través de los cuales se transportan los microorganismos pueden entrar con facilidad por los laterales de la mascarilla ya que esta no está correctamente sellada a la faz de la persona. Another feature of the mask object of the invention is its facial seal. This mask has exactly the same format as an FFP2 mask, since FFP2 mask production lines are used for its manufacture, having therefore passed the Inward Air Leakage (T.I.L.S) and comfort of fastening tests with respect to to mobility. A normal hygienic mask does not meet these requirements, since these tests are not carried out, and therefore the aerosols through which the microorganisms are transported can easily enter through the sides of the mask since it is not properly sealed. in the person's face.
La mascarilla objeto de la invención tiene una respirabilidad de 32 Pa/Cm2, lo cual es prácticamente el doble que la respirabilidad de una mascarilla FFP2, siendo esta mucho menor, normalmente rondando unos 60 Pa/Cm2. The mask object of the invention has a breathability of 32 Pa/Cm 2 , which is practically double the breathability of an FFP2 mask, this being much lower, normally around 60 Pa/Cm 2 .
Gracias los materiales empleados, su naturaleza, la disposición relativa y la forma final de unión se consigue una mascarilla higiénica reutilizable, que puede llegar a soportar hasta 20 lavados, en el que la mascarilla ofrece una protección contra microorganismos como bacterias con un nivel del 99,9% de eficiencia de filtración bacteriana. Thanks to the materials used, their nature, relative arrangement and shape At the end of the union, a reusable hygienic mask is achieved, which can withstand up to 20 washes, in which the mask offers protection against microorganisms such as bacteria with a level of 99.9% bacterial filtration efficiency.
