Description

Technology area

The proposed product is used as a personal protective pad for the face in order to prevent viral infections transmitted by airborne droplets from entering the human respiratory tract.

State of the art

A large number of personal protective equipment of various design is known from the prior art, which are capable of restraining the spread and development of viral infections. Surgical and hygiene masks and respirators are the most common face protection.

So, from the prior art, an anatomically shaped medical mask is known (see RU 182435, class A41D 13/11, publ. 2018 [1]).

The known solution [1] provides individual protection and refers, in particular, to the field of medical disposable masks.

This mask is made with the possibility of its disclosure to a cup-shaped shape to fit over the mouth and nose of the user, contains a mask body and means for attaching the mask to the user's head, and the mask body is made of a fabric with folds formed therein.

A distinctive feature of this medical mask is its unique trapezoidal shape, which follows the shape of the face and provides a snug fit, and also reduces fogging.

The disadvantage is the lack of the possibility of reuse, which leads to an increased consumption of this protection.

In this case, the closest analogue of the proposed utility model should be considered an antimicrobial medical mask, known from RU 2632636, class. A41D 13/11, publ. 2017 [2].

A well-known technical solution [2], as a rule, is used by doctors in general medical practice, but it can also be used by the population during a pandemic, in emergency situations, to protect against infections transmitted by airborne droplets.

This protective mask for protection against infections transmitted by airborne droplets is a three-layer medical pad made of spunbond.

A feature of this mask is that the spunbond pad is ultrasonically treated with a solution that has antimicrobial and antiviral effects, which allows not only to prevent infection from entering the body, but also to provide a therapeutic effect in case of illness.

The known protective mask [2] can be used repeatedly, however, it does not have the technical ability to compactly fold that does not violate the structure of the material used, which during operation will lead to loss of shape, rapid abrasion of surfaces and, accordingly, to deterioration of preventive and therapeutic capabilities.

Disclosure of a utility model

The technical problem of the proposed utility model is the creation of a reliable and reusable protective mask that can be quickly and compactly transformed into an unexploited position.

The technical result of the proposed utility model is the implementation of the purpose, which consists in the possibility of accelerated and ergonomic folding and unfolding of the product into the non-working and working positions, respectively, without disturbing the structure of the structure, which reduces material wear and, accordingly, extends the service life.

The specified technical result, providing a solution to the specified technical problem, is achieved as a result of the fact that the reusable sanitary mask consists of a protective cover made of nonwoven polymeric material covering the mouth and nose of the wearer, provided with a holding means, and the configuration of the protective cover is a structure of sequentially folded into rows folds, closing at the ends, which allows you to straighten the template while maintaining the row, obtaining a cup-shaped blank, the top of which contains alternating, stepped figured sections formed by converging the edges, geometrically determining the shape of the structure in the folded and working position.

According to one of the most preferred embodiments of the utility model, spunbond is used as the nonwoven polymer material.

According to the most promising embodiment of the utility model, the holding device is made in the form of ear grips.

According to one of the possible versions of the utility model, the retention means is made in the form of a grip enveloping the occipital part of the head.

It is advisable if the grip is made of elastic material.

It is acceptable if the grip is made of knitted material.

As a rule, in the proposed utility model, the template initially has a rectangular or square shape of a given (specific) size.

Rows of folds of the protective strip at the ends can be closed using end scraper or thread stitches.

For the best expressiveness, the face plate of the protective pad can be painted in different colors, and the grips can also be in different colors.

Based on the current state of the art in the field of antiviral and antimicrobial personal protective equipment, there is currently a need to create a special (special) protective face mask that will be technically compact folding and at the same time will have a reliable design with the possibility of repeated effective use without loss consumer properties.

To solve the indicated technical problem, it seems advisable to design a hygienic mask from a composition suitable for this purpose, namely from a non-woven polymer material, and configure it in such a way that the combination of the design and features of this material is able to achieve a complex technical effect, which consists in the real possibility of an accelerated and ergonomic folding and unfolding the proposed protective product into an unexploited and exploited position, and what is especially important, without damaging the basic structure of the product, therefore shape stability will be preserved, surface abrasion will slow down, damage during use is minimized, which creates the possibility of long-term operation with minimal loss of consumer properties ...

In this connection, a hygienic mask of repeated use is proposed, which consists of a protective cover made of nonwoven polymeric material covering the mouth and nose of the wearer, provided with a means of holding on the wearer's head.

As already mentioned, the author's intention is to use a non-woven polymer material in a protective mask, which allows air to pass through, retains its shape and sufficiently detains microbial and viral infections.

At the same time, in order to successfully solve the existing technical problem, it is proposed to configure (rework) the protective pad made of the mentioned material by folding it into rows with the formation of folds (in the form of an accordion), and the folds are bent sequentially and close at the ends, which makes it possible to straighten a kind of a template made of non-woven polymeric material while maintaining the row and thereby obtain a cup-shaped blank, the top of which is subsequently processed so that alternating stepped shaped sections formed by converging the edges are formed, which essentially determine the geometric shape (structure) of the structure in the folded and working position ...

This design of the protective pad in combination with the material used as a non-woven polymer material contributes to the creation of an easily transformable protective mask that can be ergonomically and easily transferred from the working position to the compactly folded position (unused position) and vice versa, which is actually due to the known physical properties polymeric nonwoven material and the proposed design feature, implying the presence of sequentially bent into rows of folds that retain their rows when the template is expanded, which during subsequent operation will ensure the stability and invariability of the configuration, without disturbing its structure, when moving from a working position to a non-working one, and the resulting alternating stepped curly the sections obtained by converging the edges of the folds at the apex, in fact, determine the geometry of the structure and serve as a similarity (analogs) of regulators that conditionally control and set the direction stepwise compact folding and deployment of the structure, i.e. acceptance of a work or non-work position.

In addition, the above-described design of the protective cover made of non-woven polymer material, as already mentioned above, preserves the integrity of the structure of the structure, without disturbing its structure when moving from the working position to the compact non-working position, which actually reduces the wear of the material and prolongs the service life. comprehensively increasing the reliability of use.

As can be seen from the description, the technical result, which consists in eliminating the violation of the structure of the structure, objectively manifests itself during the creation and use of the proposed product and is inevitably taken into account by a specialist, and, accordingly, is recognized as related to the technical result, which consists in the implementation of the purpose, which consists in the possibility of accelerated and ergonomic folding of the product into non-working and working positions, respectively.

Thus, it was determined that the interrelated technical results, consisting in the possibility of accelerated and ergonomic folding and unfolding, as well as the prevention of violation of the structure of the structure, are achieved as a result of the fact that:

- the protective mask consists of a protective cover made of non-woven polymeric material covering the mouth and nose of the wearer, provided with a retention means;

- the configuration of the protective lining is a structure of folds sequentially bent into rows, closing at the ends, which makes it possible to straighten the template while maintaining the rows, obtaining a cup-shaped blank, the top of which contains alternating stepped figured sections formed by the convergence of the ribs, geometrically defining the shape of the structure in the folded and working position.

These features of the proposed protective mask form a set of essential features necessary to achieve a given technical result, which allows you to solve an urgent technical problem of creating a reliable and reusable protective mask that can be quickly and compactly transformed into an unexploited position.

Implementation of the utility model

The proposed utility model is illustrated by a specific example of implementation and a specific implementation option, which, however, are not the only possible ones, but clearly demonstrate the achievement of the presented set of essential features, the solution of the specified technical problem and the achievement of a given technical result.

FIG. 1-4, the following parts and elements of the proposed utility model are presented, as well as the means involved in its implementation:

1 - protective strip;

2 - means of restraint;

3 - front surface;

4 - inner surface;

5 - carrying case;

6 - top;

7 - folds;

8 - ends of the protective strip;

9 - ribs of the folds;

10 - stepped figured sections.

And so, the reusable sanitary mask consists of a protective patch 1 made of nonwoven polymer material, which is used as a spunbond, covering the mouth and nose of the wearer (user).

The sanitary mask is equipped with a retention device 2, which is made in the form of ear grips made of elastic material located along the lateral parts.

The configuration of the protective strip 1 is a structure of folds 7 sequentially bent into rows, closing at the ends 8, which allows the resulting template to be straightened, thereby obtaining the front 3 and internal 4 surfaces, while maintaining the row, with the formation of a kind of cup-shaped blank.

The top 6 of the cup-shaped blank is processed so that alternating, formed by converging the ribs 9 of the folds 7, stepped shaped sections 10 are formed, which essentially define the shape of the structure in the folded and working positions.

The proposed utility model is carried out as follows.

On a prepared, sterilized and relatively flat work surface, a rectangular protective cover 1 made of spunbond is placed in a certain size.

The protective pad 1, in manual mode, with the help of the operator's fingers, is sequentially and completely folded into rows (accordion) with the formation of folds 7, thereby obtaining a wavy surface. The folds 7 of the protective strip 1 at the ends 8 are closed (connected) with a stapler scraper or a thread string, depending on the customer's preferences.

Next, the resulting kind of spunbond template is straightened in opposite directions with two hands to obtain, respectively, the inner surface 4 and the front surface 3, while the row of folds 7 changes, but generally remains.

Then, the final manual processing with the fingers of the surface of the apex 6 of the protective lining 1 is carried out by bringing together (convergence) in the upper part (at the apex 6) of the ribs 9 of the folds 7 to obtain pointed sections at the peak and corresponding depressions between them, so that stepped alternating curly sections 10, which actually define the shape of the structure in the folded and working position.

At the end of the assembly, on the sides of the structure, the retention means 2 are attached in the form of ear grips made of elastic material.

Depending on the wishes of the customer, the protective strip 1 can be painted in different colors, the holding device 2 can also be painted in different colors.

The reusable hygiene mask is ready for use.

In order to use this product, it is necessary to spread the protective pad 1 and attach it to the face with the inner surface 4, close the part of the nose, mouth and chin, pull the retention device 2 in the form of grips over the ears, and be sure to make sure that the edges of the protective pad 1 are as close as possible. to the surface of the user's face.

After using this hygienic mask, it is possible to fold it ultra compactly by connecting the ends 8 tightly to each other and also tightly sliding the rows of folds 7, squeezing the figured sections 10 all the way to the stop, gently insert it into the through-fitting carrying case 5.

A hygienic mask can be used many times for which the used product must be washed with soapy water under hot water, followed by drying the folded product.

Before the next use, the hygienic mask can be processed and fixed in shape with hot steam or a regular household iron.

In case of damage to the nonwoven polymer material (spunbond), the product must be disposed of as sorted waste.

It is important to note that it is the structural design of the protective pad 1 in combination with the material used, which is a non-woven polymer material, in this case - spunbond, that contributes to the creation of an easily transformable protective mask, which ergonomically and easily moves from the working position to the compactly folded position (unused position) and vice versa, which is actually explained by the known physical properties of polymeric nonwoven material, including spunbond, and by the proposed design feature, which implies the presence of folds 7 sequentially bent into rows, which retain their rows when the template is expanded, which during subsequent operation will ensure the stability and invariability of the configuration , without disrupting its structure, when moving from a working position to a non-working position, and the resulting alternating stepped figured sections 10, obtained by converging the edges 9 of the folds 7 at the vertex 6, actually determine the geometry of the structure and serve as similarity (analogs) of regulators that carefully control and set the direction of stepwise compact folding and unfolding of the structure, i.e. acceptance of a work or non-work position.

It should be borne in mind that the above-described design of the protective lining 1, as has already been mentioned more than once, preserves the integrity of the structure of the structure, without disturbing its structure when moving from the working position to the compact non-working position, which actually reduces the wear of the material and prolongs the service life, comprehensively increasing reliability of use.

Based on the foregoing, it should be argued that the technical problem to be solved and, accordingly, the specified technical result is achieved due to the fact that the proposed hygienic mask consists of a protective patch 1 of a nonwoven polymer material covering the mouth and nose of the wearer (user), provided with a retention device 2, while the configuration of the protective lining 1 is a structure of folds 7 sequentially bent into rows, closing at the ends 8, which allows you to straighten the template while maintaining the rows, obtaining a cup-shaped blank, the top 6 of which contains alternating stepped figured sections 10 formed by converging edges 9, geometrically defining the shape structures in folded and working position.

The proposed utility model can be successfully used to contain the spread of diseases transmitted by airborne droplets, in addition, this product has a pronounced and aesthetically pleasing design.
