Description

DESCRIPTION

Absorbent mask with liquid barrier.

TECHNICAL SECTOR

The present invention refers to a mask, of a sanitary type, intended to protect the health of its users.

The object of the invention is to provide a mask that, being breathable, is totally impermeable to liquids, such as droplets from the nose or mouth that are thrown when an infected person coughs or exhales.

It is also an object of the invention that the impermeability of the mask works in both directions, that is, both from the outside to the user, and from the user to the outside, all with an economic structure that makes it easily accessible to the public.

BACKGROUND OF THE INVENTION

A characteristic of the Covid-19 pandemic is its high contagion. It is known that people transmit the disease from the first moments, before showing symptoms and that there are also asymptomatic people. That is to say, they have the disease and transmit it, although they do not suffer from it.

The seriousness of the situation forces the authorities to order quarantines at enormous economic and social cost.

Obviously, quarantine is used in the absence of other measures that can resolve the situation.

The primary purpose of quarantine is to stop the spread of the virus. By reducing the number of relationships between some people and others, the chain of infections is reduced.

An alternative approach could be to take measures so that the virus carriers do not spread and that they can still lead a life without quarantine, with the savings and comfort that this would entail.

For this, it is necessary to analyze how this disease is transmitted in order to find a solution that prevents contagion.

According to the WHO "The disease can spread from person to person through droplets from the nose or mouth that are thrown out when an infected person coughs or exhales"

"These droplets fall on objects and surfaces around the person, so other people can get Covid-19 if they touch these objects or surfaces and then touch their eyes, nose, or mouth. They can also become infected if they inhale droplets spread by a person with Covid-19 when coughing or exhaling.

So it's important to stay more than 1 meter (3 feet) away from a person who is sick. "

Therefore, to avoid contagion, the key factor is to prevent these droplets from spreading.

This can be achieved by retaining them in a mask that lets air through, prevents the passage of said droplets and, in addition, absorbs them to prevent them from draining.

It is also important to avoid contamination of the hands when cleaning or touching our nose or mouth. Again, the use of the mask prevents the user from unintentionally touching these areas.

Now, many of the masks on the market are either not waterproof, or they are waterproof in one direction, that is, from the outside to the user, not foreseeing that the user himself is likely to infect other subjects before lack of symptoms or knowledge of the infection.

Although there are fully waterproof masks in both directions, they are non-breathable masks, in which respiration is carried out through carbon filters or the like, structurally complex and consequently expensive, filters that are also susceptible to saturation, for which are not the most suitable solution.

EXPLANATION OF THE INVENTION

The recommended absorbent mask with liquid barrier solves the aforementioned problems in a fully satisfactory way, based on a simple but effective solution, which does not require complicated and expensive filters, making it an economical product, easily accessible to the general public .

More specifically, the proposed solution is a mask, made of a material that prevents liquids from passing through it both from the inside out and from the outside in.

Furthermore, on the side that faces the mouth and nose, it has the ability to absorb and retain droplets, preventing them from draining and maintaining comfort for the user.

For this, it starts from a 3-layer composite fabric, consisting of a first, internal layer, that is, the one intended to come into contact with the user's skin, made of highly absorbent textile material such as viscose wadding, with at least a second layer superimposed on it, made with a material formed by very fine filaments and very close together.

This second layer is also very compact, so that due to the surface tension of the water -which is the base of the fluids that the mask must retain- they do not penetrate this second layer.

Additionally, at least one outer layer of a reinforcing material can be added to the second layer such as a fabric, a punch, a non-woven fabric (TNT), and so on.

These layers are joined to each other by ultrasonic sewing, gluing, or other usual means in the sector that do not involve the creation of holes through which the water passes.

From this material it is cut according to the usual patterns of the masks, using conventional cutting and sewing techniques, obtaining a main body to which the classic elastic bands will be attached for adaptation to the user's face.

From this structuring, a highly effective mask is achieved, which can be sterilized in boiling water multiple times to be reused again.

BRIEF DESCRIPTION OF THE DRAWINGS

To complement the description that will be made below and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical embodiment thereof, a set of drawings is included as an integral part of said description. where, by way of illustration and not limitation, the following has been represented:

Figure 1.- Shows a perspective view of an absorbent mask with a liquid barrier made in accordance with the object of the present invention.

Figure 2.- Shows an enlarged perspective detail of the material from which the mask of the invention is obtained.

Figure 3.- Shows, finally, a view similar to that of Figure 2, but in which the material layers appear partially separated for a better visualization of the mask's structure.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the figures outlined, it can be seen how the mask of the invention is of the type obtained from a pattern (1) of composite material, laminar, which by means of conventional cutting and sewing techniques, adopts a configuration as bowl, formal and dimensionally suitable to adapt to the nose and mouth of the user as shown in Figure 1, with elastic bands (2) for said adaptation, with the special feature that the main body of the mask is obtained from of a composite material, clearly visible in figure 3, in which a first inner layer (3), made of highly absorbent textile material such as viscose wadding, with at least one second layer (4), made of a material made up of very fine filaments and very close together.

The second layer is very compact, giving the mask its waterproof character in both directions.

For this, this second layer (4) is made from a material in which between 40 and 60% of polyester fiber with a hollow cross section of 5 to 8 decitex, and between 40 and 60% of siliconized cellulosic fiber, linked by hot melt polyester fibers of 3 to 6 decitex.

Additionally, at least an external third layer (5) of a reinforcing material can be added under the second layer (4) such as a fabric, a punch, a non-woven fabric (TNT), etc.

Claims (2)

1a.- Absorbent mask with liquid barrier, which being of the type obtained from a laminar pattern (1) of composite material, which by means of cutting and sewing techniques adopts a cup-like configuration, formal and dimensionally suitable for adapt to the nose and mouth of the user, with elastic bands (2) for adaptation, characterized by the fact that the main body of the mask is obtained from a first internal layer (3) of highly absorbent textile material, such as a wadding with viscose, and at least a second layer (4), made with a material formed by very fine filaments and very close together, in which between 40 and 60% of hollow cross-section polyester fiber participate 5 to 8 decitex, and between 40 and 60% of silicone cellulose fiber, linked by hot melt polyester fibers of 3 to 6 decitex. 2a.- Absorbent mask with liquid barrier, according to claim 1, characterized in that it includes an external third layer (5) of a reinforcing material under the second layer (4) such as a fabric, a punching or a non-woven fabric.
