ADHESIVE ANTI-MIST FACIAL MASK

OBJECT OF THE INVENTION

The object of the present invention is to present a facial mask, both of the surgical type and of the filtering half mask type (hereinafter "mask / s"), so that, in a simple and fast way, it adheres to the face in its upper area. Specifically, the adhesive part would coincide joining both cheekbones, passing over the nasal bridge. It should be said that this statement is relative, depending on the facial features of each person; intends to estimate the area of the face that will be covered with the adhesive part of the mask.

With this invention, the air expelled, both through the nose and the mouth, is prevented from escaping through the upper part of the mask, and fogging the user's glasses by becoming mist, due to the difference in temperature between the lenses and the air. coming out of the body.

This solution would involve any type of glasses: prescription glasses, protective glasses and sunglasses.

It also helps to avoid inhaling or exhaling air that does not pass through the filter, through the upper area, thus improving its efficiency.

It also contributes to a better hold of the mask, due to the adhesion, it helps the function of the elastic strips, and can even eliminate them.

It concerns the health sector in the case of surgical masks, considered Health Product (PS); and also to the Health and Safety sector, industrial or not, since filtering half masks are included in the Individual Protection Elements (PPE), due to their function of protecting the user from airborne particles.

BACKGROUND OF THE INVENTION

In 2020, the COVID-19 pandemic is hitting the entire planet. That is why the use of masks has exploded globally, and from being an article practically unknown to most, in many places and particularly in Spain, they have become an almost indispensable element in daily life.

The mask is an article designed to cover the nose, mouth and chin and avoid inhalation and / or exhalation of certain particles or pathogens, depending on each type of mask. It is held in position by 2 elastic straps that hold it by the ears, or by surrounding the entire head.

Because the majority of Spaniards had barely worn one in their lives, the complaints soon began to be made public: stress, heat, pain in the ears or even allergies; in addition to difficulty in obtaining the masks. But one of the most widespread and important problems for coexistence with masks is that of the fogging of the glasses.

The mask does not allow the air to escape from the front with the usual ease, and it escapes through the gaps that it may find, on the sides, from the bottom or from the top. However, if the person wears any type of glasses, the air that comes out of the upper part at body temperature clouds the lenses of the glasses, which are at a lower temperature. Consequently, the mist formed obstructs vision.

It is true that many types of mask include some type of wire, plate or a layer of foam on the upper part, in order to adjust it to the nasal bridge and try to alleviate this situation, but it is really a measure whose results are not satisfactory in the face of to the problem presented.

Currently there is no mask in place to prevent fogging, damage to organic lenses, allergies and pain in the ears.

The present invention proposes a mask composed, as usual, of a filter element and a fixing element, and it also consists of an area prepared to adhere to the skin with a hypoallergenic adhesive (low probability of allergic reaction).

DESCRIPTION OF THE INVENTION

The present invention refers to a mask that by itself has an effective system that prevents the air expelled through the nose or mouth from escaping upwards, thus fogging up any type of glasses that the user is wearing. This system is based on a layer of adhesive that is characterized by being hypoallergenic.

These types of adhesives are tested and it is known that they do not react with the skin, in fact, they are currently used in dressings surrounding open wounds, plasters or special wig tapes; In addition, its effectiveness is known for hours being subjected to daily activity, sweat and movement.

The mask can be divided into 3 basic components: filter body, adhesive zone and fastening strips.

- The filtering body is the part that covers the nose, mouth and chin, and its purpose is to filter the inhaled and / or exhaled air, more or less effectively according to its classification. Made up of synthetic fabric, polyester or other synthetic fibers, it includes one or more layers that act as a particle filter. These filter layers are made up of TNT (non-woven textile), made up of fibers joined by methods other than weaving or spinning, such as mechanical, chemical or thermal. This system of tangled non-woven fibers presents a bacterial protection (among others), superior to any system of woven fibers. In the case of surgical type masks, the degree of protection is up to 80% according to their classification into type I, II and IIR; and only in the exit direction, that is, they do not protect the user, but they do filter the air expelled by the user. In the case of a filtering half mask, the user is protected, and the European standard establishes 3 levels of protection according to the filtration efficiency: FFP1 (78% efficiency), FFP2 (92% efficiency) and FFP3 (98% efficiency) . Other regulations outside of Europe establish other levels such as N95 or KN95. The present invention can consist of any of the types of mask mentioned, and consequently their different geometries: the surgical mask is rectangular, while the filtering half masks have an oval shape. In any case, the filter body acts as a support, in which the adhesive area is integrated.

- The adhesive area is located on the inside of the filter body, in the upper part. It can consist of one or more distinct areas, in the form of one or more elongated strips. This area or areas, on its outer face has a layer of hypoallergenic adhesive, so that, without danger to the skin, it adheres to it by drawing the contour of the face in the upper part of the mask, that is, from cheekbone to cheekbone, passing over the nasal septum (intuitively, since facial features differ in each person). In this way, the mask remains adhered to the skin in such a way that it does not allow air flow through the upper area of the mask, preventing it from circulating towards the eyes and can fog up any type of glasses that may be being used.

- The support straps are made of more or less elastic material, designed to surround the ears and hold the mask on them, or surround the entire head and offer a better and more comfortable hold than the previous one. There are 2 strips that have a total of 4 points of union with the body, on its sides or corners.

The product is also made up of another important part, located on the surface of the hypoallergenic adhesive, which is the protective film. It is an element composed of a strip of paper or plastic, easily removable with your fingers just before using the mask. Thus, the deterioration of the adhesive, dirt and loss of effectiveness are avoided until the moment of use.

This invention joins the masks with the adhesive elements and their protective component or protective film. It is a mask characterized by having a strip of easy adhesion, achieving the adhesion of the mask to the face in the upper area of the same, and avoiding the escape of air towards the upper part, and therefore, towards the glasses. This prevents them from fogging up.

In reference to applicable regulations, the filtering half mask must comply with the requirements of UNE-EN 149: 2001 + A1: 2010. The surgical mask must comply with what is specified in UNE-EN 14683: 2019 + AC: 2019.

Thanks to the technical improvement, the adherence is maintained for the entire time the mask is worn, to ensure that the air does not escape upwards, fogging the glasses and disturbing the vision.

At the same time, this system allows a better closure, reducing to a minimum the amount of air that can be inhaled or exhaled through the upper area without passing through the filter, and increasing its efficiency, which leads to an improvement in the primary purpose of the mask, which is the protection of the individual.

A great advantage is obtained in the manufacture, because the design of the innovation dispenses with the wire or plate that current masks have, with the consequent savings in material and time, since these wires are usually inserted between layers of fabric and subsequently sewn or sealed so that they cannot come out and harm the person. A protective film is included over any existing adhesive area, which will be easily removed just before placing the mask, as is the case with current dressings, for example.

This document describes two options that can be used for mass production; These are defined in greater detail below:

- A strip with one of its adhesive faces and protected with a protective film is added in the correct location of the mask. This face is clearly positioned outward. During the manufacture of the mask, this strip can be sewn in place, so that the manufacturing mode would hardly be modified, only including a coil of adhesive strip that takes advantage of the seam or welding that was already being done previously. Introducing the exact measure in the cutting machine, it would consist of a quick and easy operation to implement in existing machinery. Apart from the advantage of not having to insert the wire, as already explained.

- A layer of hypoallergenic adhesive is included in the corresponding area of the mask, by spraying, on which a strip of the same size of protective film is immediately applied.

In tests carried out, it has been found that this system stops the discomfort that the use of the mask can cause to some users in the ears, in the case of masks that only have a strip or rubber on each side to hold it by the ears. It allows to be attached from the front, helping to hold it. Thanks to this new adhesion zone, these rubber bands can be eliminated and the mask kept in position without having to be held by them, with the savings in time, manufacturing cost and ear discomfort that this entails.

This leads to the presentation of a different variety of anti-fog adhesive mask, which not only consists of an adhesive zone on the upper part, like the one already described, but also consists of 2 or more adhesion points on the sides of the mask, or in its lower corners in the case of being rectangular. These additional zones are smaller (up to 2 cm in radius) and round in shape.

BRIEF DESCRIPTION OF THE DRAWINGS

To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, a set of drawings is attached as an integral part of said description, in which, with an illustrative and non-limiting nature, the following has been represented following:

Figure 1.- Shows a view of the inner face of a surgical mask, with the adhesive area in shaded tone.

Figure 2.- Shows a view of a face in profile, with a mask in place. You can see the adhesive area, so that its approximate location is understood.

Figure 3.- Shows a view of a face from the front, with a mask in place and glasses. You can see the adhesive area, so that its approximate location is understood. The location of two adhesive areas is also shown for the case of a mask that will eliminate the fastening strips, in favor of the adhesive areas.

The elements that make up a conventional mask can be seen in the figures: filtering body (1), elastic fastening rubbers (2) and, in this case, the adhesive area object of the invention (3).

Once it is placed, the shape that this area draws is checked once it is attached to the face, crossing the nasal septum (4). In the front view, a location of said adhesive area (6) with respect to the glasses (5) can be elucidated. The position of 2 adhesive areas (7) is also observed, which, if applicable, would make up a mask that lacks fastening strips.

PREFERRED EMBODIMENT OF THE INVENTION

The system according to the present invention is described below with reference to the attached figures. Specifically, Figures 1,2 and 3.

The innovation presents a mask with a surface area of up to 250 cm2, whose body is made of synthetic fabric, polyester or other synthetic fibers (1), which includes one or more layers of filtering component (made up of non-woven textile, TNT) and integrates into the upper part of its inner face a layer of hypoallergenic adhesive (3). The hypoallergenic adhesive layer (3) is protected with a protective film, easily removable with the fingers, made up of a strip of paper or plastic, which covers the entire surface of the hypoallergenic adhesive, until the moment of use, to prevent it from dirt sticks and / or its properties are lost.

The hypoallergenic adhesive layer (3) preferably has dimensions of 5-20 cm wide by 0.5-2 cm high, presenting a rectangular geometry, as shown in FIGURE 1, allowing the mask to adhere to the skin, perfectly following the shape of the user's face (6), in the area that covers the upper limit of the mask, that is, an area below the eyes (where the glasses (5) are located), located between cheekbones and cheekbones, above the nasal septum (4).

This new anti-fog adhesive mask has a thickness of at least 1 mm in the area of the hypoallergenic adhesive (3).

In turn, the closure in this area is improved, contributing to greater efficiency in filtering inhaled and exhaled air, a basic function of masks.

The fastening of the mask is based on 2 strips or elastic bands (2) attached to the body at 4 points, in such a way that, depending on its scope (ears or full head), they keep the mask fastened in position.

However, it also innovates in the fastening of the mask, since by remaining adhered to the face by means of hypoallergenic adhesive (3), it is possible to dispense with other fastening methods such as ear rubbers (2). In this case, two or more adhesive areas would be included on the sides or corners of the mask (7), with a round shape up to 2 cm in radius, and also protected with a protective film. In this way, the maximum number of differentiated adhesive areas that the mask can comprise in total is six.
