Description

DESCRIPTION

Anti-fog mask

TECHNICAL SECTOR

The present invention refers to a protective mask against viruses, germs and bacteria present in the air.

The object of the invention is to provide a mask that, in addition to offering a safe means of filtering inhaled/exhaled air, includes means that prevent exhaled air from being projected upwards over the cheeks, thus preventing it from passing through the cheeks. the lenses of the glasses and produce the corresponding condensation.

It is therefore the object of the invention that the mask adapts better to the user's physiognomy, making the mask safer.

BACKGROUND OF THE INVENTION

Due to the pandemic caused by COVID-19 and the great demand for barrier systems and products, there has been an unprecedented movement worldwide in the use of masks, advised by health authorities in order to prevent the spread of this disease. .

If this pandemic has shown anything, it is that glasses and a mask do not work well. The difficulty of combining both lies in the difference in temperature between the concentrated air that we exhale and the temperature of the outside environment, which will cause the glasses to fog up.

Under normal circumstances, exhalation will project it forward and away from us, but the purpose of the mask is to precisely slow down the process. As a result, air escapes upwards, passes through the corners of the mask opening around the nose and over the cheeks, passes through the goggle lenses and produces condensation.

If we are in a cool environment, on a typical spring morning, the problem will be even greater.

EXPLANATION OF THE INVENTION

The recommended anti-fog mask fully satisfactorily resolves the aforementioned problems, based on a simple but effective solution.

For this, and based on the conventional structuring of a filtering mask, whether hygienic, surgical or FFP2, the mask of the invention focuses its characteristics on the fact that it incorporates on its upper edge a band made up of three different superimposed sheets, one self adherent, another absorption and a third that exerts perspiration.

More specifically, the self-adhesive sheet has a multi-perforated structure with a 2-millimeter diameter die, adapting to the mask and the skin without showing its use at all.

For its part, the absorption sheet occupies the intermediate position of the three sheets, and its function is to absorb sweat and mist, helping the skin to perspire through the outer sheet.

Finally, the last sheet, the outer one, consists of a perspiration sheet.

This sheet, like the self-adhesive sheet, has 2-millimeter-diameter die-cut perforations for better absorption of mist from breathing and perspiration from the skin, with an adaptability to the mask that makes it impossible to see anything in the use in the anti-fog band.

The band will present its fixing edge to the upper edge of the straight mask, while its upper free edge will present a sinuous contour in which at least two prominent sectors are defined on both sides of the nose that adapt/adhere to the user's cheeks, significantly improving the adaptation of the mask to the user's face.

Through a heat-sealing process, the three sheets remain attached at the upper perimeter of the mask, leaving the inner absorption sheet unattached to the adherence and perspiration punch-outs, so that each one of them acts individually and thus achieve adequate functionality both in adherence and in absorption and perspiration, achieving an optimal sensation of comfort in its use.

The procedure for use is exactly the same as a conventional one for both surgical and FFP2 masks.

First, we place the mask over the nose and mouth, passing the elastic bands behind the ears.

The anti-fog foil will ensure that there is no space left.

Next, we will pinch the nose clip to adjust it and it will work perfectly.

In this way, a mask is achieved that not only prevents the glasses from fogging up, but also offers a better adaptability of the mask to the user's face, thus being much safer than conventional masks.

BRIEF DESCRIPTION OF THE DRAWINGS

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

Figure 1.- Shows a rear perspective view of an anti-fog mask made according to the object of the present invention.

Figure 2.- Shows a front perspective view of the device of the previous figure.

Figure 3.- Shows a diagram of the multi-layer structure that participates in the anti-fog band, before being die-cut and sealed.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the figures outlined, it can be seen how the invention is based on the conventional structure of any mask, whether hygienic, surgical or FFP2, in which a main filtering body (1) and elastic bands (2) of fixation.

Well, in accordance with the essence of the invention, it has been foreseen that the mask incorporates fixed to its upper edge (3) an anti-fog band (4) composed of three superimposed sheets, a self-adhering sheet (5) , an absorption sheet (6) and a perspiration sheet (7), where the self-adhesive sheet (5) has a plurality of holes (8) of 2 millimeters in diameter, like the perspiration sheet (7). ) that incorporates a plurality of holes (8') of 2 millimeters in diameter.

As can be seen in figures 1 and 2, the anti-fog band (4) has its fixing edge to the upper edge (3) of the mask straight, while its free edge will have a sinuous contour in which the define at least two prominent sectors (9) on both sides of the nose that adapt and adhere to the user's cheeks.

The self-adhesive sheet (5) will preferably be obtained from low-density polyethylene with an adhesive with the following properties:

For its part, the absorption sheet (6) will preferably be made of 20 g Melt-Blown microfiber non-woven fabric.

Finally, the transpiration sheet (7) will be made of 25 g polypropylene.
