Description

DESCRIPTION

Washable and reusable three-layer hygienic mask

Technical sector

The present invention belongs to the field of masks and, specifically, to the field of hygienic masks.

The invention consists in providing the main body with a hygienic mask with three differentiated layers. This three-layer composition of the main body of a hygienic mask, which did not exist to date, allows adequate filtration (barrier) efficiency and breathability. In addition, the composition in three layers allows them to be combined by choosing different materials and / or weight measures for each one of them. This allows different versions of the same mask to be made so that it adapts to different circumstances, depending on the type of use that you want to give it or the weather conditions of the place and / or time in which it is used.

With this new configuration based on three layers, it is possible to:

1. - Provide a hygienic mask with adequate filtration and breathability efficiency to perform the contagion prevention function while allowing sufficiently comfortable breathing for prolonged and intensive use.

2. - That there may be different versions of the same hygienic mask model that correctly perform the function set forth in the previous point, and that each of these versions is in turn suitable for different uses required by each user, the activity carried out. , the place where you use it or the time of year in which it is, among other circumstances.

Background of the invention

The existing hygienic masks to date (date on which priority is requested) were not intended or designed for the daily and intensive use that today is given as a consequence of the new challenges posed for humanity by the COVID-virus. 19. Until now, it was common to use masks to carry out different jobs or scenarios where the user was exposed to certain factors almost always related to the presence of an atmosphere or air harmful to human respiration. Today, by virtue of the unprecedented experience posed by the COVID-19 virus pandemic, the use of hygienic masks is already mandatory globally for all people and in any area of their day-to-day life.

In this scenario, one of the main drawbacks of the existing hygienic masks was that, having their main body configured with only one layer or, at most, one layer to which a filter is incorporated, it was not possible to achieve simultaneously sufficient efficiency as a protective barrier and adequate breathability. Commercial cotton cloth masks, for example, were generally highly breathable but offered little filtration.

This configuration also did not allow different versions of the same mask to coexist, each one designed to be used in different circumstances and conditions, preserving its functionality, efficiency as both a protective barrier and breathability.

These drawbacks are overcome, however, with a hygienic mask configuration based on three layers. In the first place, because the simultaneous efficiency of filtration and breathability is achieved by choosing materials that perform the following functions according to the layer in which they are included: in the inner layer, materials that, above all, are moisture-absorbent. It should also be perspiring and antibacterial; an outer layer of repellent material that limits the entry of external contamination; and an intermediate layer that acts as a filter and / or traps the droplets. Secondly, because the composition of the main body in three layers allows, while preserving the previously exposed functions, to choose different combinations of materials and / or also of measurements (gr) of which each layer is composed, in such a way that different combinations allow specific characteristics for specific uses, preserving its effectiveness and appearance. The choice of some materials instead of others, or the specific weight of each of them, allows optimizing the use of a mask to adapt it, for example, to warmer or colder climates, more humid or drier, to activities more intense or more sedentary.

So much so, that this is already a reality and, based on this three-layer composition, we have already achieved the utility model of a hygienic mask model that fulfills the functions of adequate breathability and filtration and that also comes in two versions different:

- WASHABLE AND REUSABLE THREE-LAYER HYGIENIC MASK. Application number:

202000181. Presented by this same applicant on April 28, 2020. It is the basic model whose utility model was granted on January 20, 2021 and published on January 26, 2021.

- ADAPTED WASHABLE AND REUSABLE THREE-LAYER HYGIENIC MASK. Application number: 202000183. Submitted by this same applicant on April 29, 2020. It is the summer model and / or for more intense activities.

Both models, based on three layers, have the same design or external appearance and fulfill their preventive function with similar efficiency. What differentiates them, therefore, is how the three layers have been combined in each one.

- For the first model, the following were chosen: i) Cotton for the outer face (percentage 205gr); ii) Polyester in the middle zone as a barrier (percentage 200gr); iii) Moisture absorbent, breathable, repellent and antibacterial synthetic fiber for the inner face (percentage 130gr).

- For the adapted model: The material and weight of the outer layer were modified, changing the 205 grams of cotton for 130 grams of synthetic fiber, maintaining the material and percentages of the intermediate and inner layers. This change meant that the mask, with the same filtration efficiency, was even more breathable and lightweight, allowing it to adapt to intense activities or hotter climates.

In this way, it has been achieved that the same hygienic mask model can be used in different conditions. Thus, the basic mask is designed for a colder climate and low intensity activity, while the adapted mask is designed for a hotter climate and more intense activity. Other combinations can even achieve that said design can be adapted to other circumstances.

Being the use of the hygienic mask, nowadays, mandatory at a global level, it was necessary to create a system that would allow to achieve an adequate filtration and an adequate breathability. In addition, it was also necessary that the same mask could be adapted to the specific circumstances of each user, that is, the place where they live, the time of year in which it is intended to be used, the type of activity that is going to be carried out with mask, etc. A certain mask may be appropriate to be used in the month of August and in Seville, and not to be used in Burgos in the month of January; and the same if we talk about an athlete and someone who leads a more sedentary day to day. To understand what we are talking about, we can think of the following: A person may have found a mask whose design is comfortable for him because of its support, for example, or because it is comfortable in the area of the nasal bridge, but that is not useful for sports or too light for very cold climates. With this new three-layer feature, we could manufacture the same mask, preferred by a certain user, and adapt it to different types of use while preserving the rest of its characteristics and design.

This is what has been achieved with the incorporation of three layers in the main body of a mask. The challenge was to find a formula so that a hygienic mask could fulfill its preventive function for COVID 19 and could also be adapted to different circumstances. This is achieved by creating a main body with three layers instead of one and even two.

By having three layers, you can choose different materials, different combinations and relative importance (weight) of them, in such a way that the intended comfort purposes for each circumstance are achieved.

Explanation of the invention

The three-layer main body of a mask must be composed of:

i) An outer layer: for this layer, materials will be sought that mainly fulfill the function of acting as a first protective barrier, that are breathable, repellent and antibacterial;

ii) An intermediate layer: materials will be sought to serve as a filter and protective barrier;

iii) An inner layer: materials that are moisture absorbent, breathable and antibacterial will be sought.

This three-layer base of the main element or body allows choosing the most suitable materials for each of the layers, the most convenient combination of them and / or the greater relative importance of some with respect to the other, in such a way that it is achieved a versatility and adaptation to different subjective and / or objective circumstances as we have explained.

Preferred embodiment of the invention

The main body of a three-layer mask is manufactured as follows:

Before making the fabrics, the fabrics are folded on an elongated table, the cut measurements of the right and left side of the three layers are marked. The sum of all this is a cycle. We take this same process to 80 cycles so that the fabric cutters take out a greater quantity of product for clothing in the same cutting time. During the cut in the upper part of the fabric they make a notch (small cut in fabric to differentiate), so once the fabrics are put together we know at first glance which is the bottom and the top.

With this process it is possible to have the fabrics or materials faced (right-left) and saves time. Once the left and right sides are facing, the three layers are joined to the center, the product is laid flat and the label is sewn on the bottom.

From the upper half, a textile piece of cloth is placed to later reinforce the placement of the element used to achieve adjustment in the area of the nasal bridge. Then the piping is placed that reinforces and finishes the contour of the product in the upper and lower part. A Once this is finished, the left and right ends are trimmed, to place the mask fasteners. Finally, loose threads are reviewed and bagging is carried out.

This manufacturing process is indicative and, depending on each model of hygienic mask, it may be altered.
