Patent Description:
In particular, the present invention relates to a facial hygiene mask able to allow a better adherence to the face.

Face masks are useful in a variety of medical, industrial or household applications by protecting the wearer from inhaling dust and other dangerous contaminants through the mouth or the nose, such as of virological kind, sprinkled into the air of an environment.

A hygienic mask, also known as a surgical mask, medical mask, or medical face mask is a device intended to be worn by a user, particularly in the healthcare field, in order to avoid the scattering of pathogens ( such as bacteria or viruses) sprinkled in respiratory and aerosol droplets that can escape from the wearer's mouth and nose.

Surgical masks can also be worn all year round to reduce the possibility of spreading airborne diseases and to prevent the inhalation of dust particles created by air pollution.

A particular type of hygienic mask are dust masks which serve as protection against more or less thin, solid or liquid, particles suspended in the air and against aerosols.

The simplest hygienic mask can be made with a portion of flexible paper, to be used against non-toxic dusts. It does not provide protection from airborne toxic hazards and is not subject to the required approvals for filtering masks. Most of the hygienic masks on the market are, on the other hand, made from more or less thick fibers and generally made with a thin net of synthetic polymeric fibers, also known as non-woven polypropylene fabric, which is produced through a highly specialized process called cracking or melt blowing, which forms the inner filtration layer.

The use of face masks is especially useful in the healthcare field to help prevent the spread of diseases and viruses. The face masks worn by healthcare professionals and patients help reduce infections in patients by filtering the air exhaled by the wearer, thus reducing the number of harmful organisms or other contaminants released into the environment. In addition, face masks protect healthcare workers and patients by filtering contaminants and microorganisms in the air.

For optimum effectiveness, the mask must be correctly adjusted to the face, in particular by covering the mouth and part of the nose. When using a mask worn correctly, the heat and humidity of the user's exhaled breath tend to concentrate inside. When the humidified air escapes from the face mask, it can condense on the user's goggles or face shield causing fogging, which can obstruct the user's view. Incorrect application represents a risk as it can allow a harmful agent to completely pass through the mask.

In this regard, an adherence device is used on the upper part of the mask, for example made by means of an elongated element, or a strip, of the rigid and flexible type which guarantees the moldability of the same and the adherence of the mask around the portion of the nose affected by coverage. This elongated element is typically made of metal or plastic material and provides for an application on the upper edge in contact with the nose of the mask itself.

The use of the elongated moldable element, however, requires the need to fix the same in specific portions of the mask, increasing the complexity and production costs of the same.

In addition, the use of the elongated moldable element causes a high difficulty of disposal, whenever is not easy to remove the metal element before disposing of the mask itself.

It would therefore be desirable to have a face mask capable of minimizing the drawbacks described above. In particular, it would be desirable to have a face mask capable of ensuring the positioning of the mask and the sealing of the humidified air in the direction of the upper edge, while preserving the characteristics of reliability. Furthermore, it would be desirable to have a face mask capable of guaranteeing the aforementioned characteristics while having a reduced size and cost. Likewise, it would be desirable to have a face mask capable of guaranteeing safety in use and environmental sustainability.

For this purpose, the numbering of the same elements with reference to different embodiments and examples not according to the invention has not been changed.

The present invention refers to the Patent Application in <CIT>, to the Patent Application in <CIT>, to the Patent Application in <CIT>, to <CIT>.

<FIG> illustrates a schematic view of the facial hygiene mask <NUM> of the present invention, according to a first embodiment.

As shown in <FIG>, the facial hygiene mask <NUM> is of the surgical type, therefore the present invention will be described below according to its characteristics, but the inventive concept can likewise be applied to masks of different types, for example of the dust masks type.

The facial hygiene mask <NUM> comprises a body mask <NUM> configured to be positioned in use on a portion of a user's face including the mouth and at least part of the nose in order to isolate the facial portion from the environment so that the air breathing is directed towards the body mask <NUM> itself.

The body mask <NUM> comprises an inner portion <NUM> and an outer portion <NUM>, the latter illustrated in greater detail in <FIG>.

The term "inner portion" means, in the present invention, the portion configured to be in contact in use with the face portion.

The term "outer portion" means, in the present invention, the portion configured to be in contact in use with the environment.

The body mask <NUM> is delimited by an upper edge <NUM> and a lower edge <NUM>, opposite the upper edge <NUM>.

The term "upper edge " means, in the present invention, the edge configured in use to be arranged in correspondence with the nose.

Furthermore, the same body mask <NUM> is delimited by a pair of lateral edges <NUM> interposed between and adapted to connect the aforementioned upper edge <NUM> and lower edge <NUM>.

The facial hygiene mask <NUM> is preferably of the three-layer type, made by means of two layers of non-woven fabric material between which melt-blown material is interposed. The latter acts as a filter that prevents microorganisms from entering or exiting the facial hygiene mask <NUM>.

The facial hygiene mask <NUM> is also provided with a plurality of folds <NUM> which extend in the horizontal direction of the body mask <NUM>. The folds <NUM> make it possible to adjust the facial hygiene mask <NUM> in the vertical direction so as to allow it to adapt to the user's face by covering the area of the face extending from the nose to the chin as well as to create a breathing chamber for the exhaled air.

The term "horizontal direction" means, in the present invention, the direction that develops along the width of the body mask when in use.

The term "vertical direction" means, in the present invention, the direction that develops along the length of the body mask when in use.

The term "transverse dimension" means, in the present invention, the dimension which refers to the vertical direction of the body mask when in use.

The term "longitudinal dimension" means, in the present invention, the dimension which refers to the horizontal direction of the body mask when in use.

The folds <NUM> on the inner portion <NUM> of the facial hygiene mask <NUM> are folded in the vertical direction and, therefore, towards the face and eyes of the user. This arrangement of folds <NUM> can be problematic as the humidity in the air flow in the facial hygiene mask <NUM> can be directed upwards, or in the direction of the user's eyes where goggles and visors can be placed with consequent fogging.

The facial hygiene mask <NUM> according to the present invention is therefore provided with an adherence device, consisting of an adherence band <NUM> adapted to be arranged on the inner portion <NUM> at the upper edge <NUM>. This adherence band <NUM> is provided with an adhesive surface <NUM>, in use in contact with the nose, and with a coupling surface, coupled to the body mask <NUM> and illustrated in greater detail in <FIG>. The contact and adhesion of the adhesive surface <NUM> to the user's nose are guaranteed by an adhesive with which the aforesaid adhesive surface <NUM> is provided.

The positioning of the adherence band <NUM> with respect to the body mask <NUM>, although this is defined as arranged on the inner portion <NUM> at the upper edge <NUM>, can be carried out in different ways, below described but not illustrated. In the first embodiment illustrated therein, the adherence band <NUM> is coupled to the inner portion <NUM> of the body mask <NUM>.

On the other hand, according to a different embodiment (not shown) the adherence band is coupled to the outer portion, and such the outer portion provided with the adherence band is folded over the inner portion. In this way, while being coupled with the outer portion, the adherence band is able to be arranged at the inner portion, for coupling and sealing with the user's face portion, when in use.

Alternatively, according to a different embodiment (not shown), the body mask comprises a pocket provided with an opening at the inner portion, and the adherence band is arranged inside the aforementioned pocket with the adhesive surface arranged at the opening.

These arrangements allow to make the facial hygiene mask according to a plurality of ways such as to guarantee a precise and economical realization.

In the embodiment herewith illustrated and discussed, the adherence band <NUM> extends substantially along the entire upper edge <NUM>. In this way, ensuring the possibility of adhesion even to the portions of the face arranged laterally with respect to the user's nose.

Different sizes of the adherence band are also possible, for example by providing a reduced length extension with respect to the length extension of the upper edge. The coupling of the facial hygiene mask <NUM> to the portion of the user's face, to cover the mouth and the nose portion, is achieved by means of a tie-on type system, which consists of four straps <NUM> which must be tied behind the head of the same user.

Different coupling possibilities are further possible, for example by means of elastic straps fastened behind the head or, more commonly, by means of ear loops, in which a cord is attached to the body mask <NUM> and is positioned behind the ears. Following the positioning of the aforementioned coupling elements to the user's face, the mask <NUM> is positioned in such a way as to ensure coupling with the portion of the face concerned. The solution envisaged in the present embodiment, i.e. the presence of the adherence band <NUM>, allows to correctly define and maintain the position of the facial hygiene mask <NUM>, in such a way as to allow the adhesion of the upper edge <NUM> to the nose without using of deformable metal elements. In particular, the adhesive provided on the adhesive surface <NUM> guarantees the impossibility of detaching the portion at the upper edge <NUM> of the body mask <NUM>, both during the mandibular movement and during the production of humidified air.

In this embodiment, the facial hygiene mask <NUM> is provided with a covering element <NUM> of the adhesive surface <NUM> suitable for preserving the adhesive before use. This covering element <NUM> is arranged at the lower edge <NUM> on the inner portion <NUM> and provided with a covering surface <NUM>, before the use in contact with the adhesive surface <NUM>, and a coupling surface, coupled to the body mask <NUM>.

The covering element <NUM> therefore guarantees a high lifecycle of the adherence band <NUM>, making the adhesive available at the time of use. In particular, by means of the solution according to the present invention it is possible to correctly define the position of the facial hygiene mask <NUM>, in such a way as to allow the adhesion of the upper edge <NUM> to the nose without the use of deformable metal elements. The arrangement of the covering element <NUM> also ensures that it prevents its dispersion into the environment.

The positioning of the covering element <NUM> with respect to the body mask <NUM>, although this is defined as arranged on the inner portion <NUM> at the lower edge <NUM>, can be carried out in different ways, as described below but not illustrated. In the first embodiment, illustrated therein, the covering element <NUM> is coupled to the inner portion <NUM> of the body mask <NUM>.

Instead, according to a different embodiment (not shown) the covering element is coupled to the outer portion, and such the outer portion provided with the covering element is folded over the inner portion. In this way, while being coupled with the outer portion, the covering element is arranged at the inner portion, for coupling with the adherence band, when in use.

Alternatively, according to a different embodiment (not shown), the body mask comprises a pocket provided with an opening at the inner portion, and the covering element is arranged inside said pocket with the cover surface arranged at the opening.

In the embodiment herewith illustrated and discussed, the covering element <NUM> extends substantially along the entire lower edge <NUM>, preferably in such a way as to correspond to the adherence band <NUM>. In this way, guaranteeing the possibility of fully preserving the adherence band.

Different sizes of the covering element are also possible for example by providing a reduced length extension with respect to the length extension of the lower edge. The covering surface <NUM> in the operative position is coupled with the adhesive surface <NUM>, in such a way as to arrange the inner portion <NUM> folded on itself, not accessible to the user before use (not shown). Similarly, the same covering surface <NUM> in the non-operative position is separated from the adhesive surface <NUM>, in such a way as to arrange the inner portion <NUM> accessible to the user for use as shown in <FIG>.

In this way, it is possible to protect the inner portion from the external environment when the hygienic facial mask is not in use.

In particular, the adhesive surface <NUM> is provided with repositionable adhesive. In this way, it is possible to use the facial hygiene mask several times.

The facial hygiene masks according to the embodiments described above can also be provided with a treatment on the body mask designed to improve the coupling of the other elements.

In particular, this treatment allows to modify the surface of the body mask, or one or more of its portions, in such a way as to facilitate coupling with the other elements.

By way of example, it is possible to carry out this treatment in the inner portion of the body mask suitable for coupling with the adherence band and in the portion suitable for coupling with the covering element. In this way it is possible to allow a better adhesion of the aforesaid elements to the body mask, in particular at the relative coupling surfaces.

Similarly, it is possible to carry out this treatment in the outer portion of the body mask, if the aforementioned elements relating to the adherence band and the covering element are arranged on this portion.

Finally, the treatment may be necessary, or preferable, even if the thickness element is to be applied, in accordance with one of the embodiments previously described.

The object of the present invention is further achieved by a method of manufacturing a facial hygiene mask, in particular of the facial hygiene masks according to the embodiments described above.

The method of manufacturing a facial hygiene mask <NUM> comprising a step of manufacturing the body mask <NUM> comprising the inner portion <NUM>, the outer portion <NUM>, at least the upper edge <NUM> and the lower edge <NUM>, opposite the upper edge <NUM>.

An application step is carried out to arrange the adherence device in correspondence with the upper edge <NUM> and constituted by an adherence band <NUM> adapted to be arranged on the inner portion <NUM> and provided with the adhesive surface <NUM>, provided with adhesive, and with the coupling surface <NUM>, coupled to the body mask <NUM>.

A further phase of application of the covering element <NUM> to the adhesive surface <NUM> designed to preserve the adhesive before use. In particular, the step of applying the covering element <NUM> comprises the step of arranging the covering element <NUM> at the lower edge <NUM> on the inner portion <NUM> and providing said covering element (<NUM>) with the covering surface <NUM>, before the use in contact with the surface <NUM> adhesive, and with a coupling surface <NUM>, coupled to the body mask <NUM>.

Preferably, the covering surface <NUM> in the operative position is coupled with the adhesive surface <NUM>, in such a way as to arrange the inner portion <NUM> folded on itself, not accessible to the user before use. Even more preferably, the adhesive surface <NUM> is provided with repositionable adhesive.

<FIG> illustrates a schematic view of the facial hygiene mask <NUM> of the present invention, according to a fourth embodiment, which corresponds to the facial hygiene mask <NUM> according to the first embodiment, illustrated in <FIG>, to which reference is made mutatis mutandis. Therefore, only the differences with respect to this first embodiment will be described in greater detail below.

The adherence band <NUM> comprises a deformable thickness element <NUM> interposed between the adhesive surface <NUM> and the coupling surface <NUM>. The thickness element <NUM> is, therefore, capable of defining a thickness between the aforementioned surfaces <NUM>, <NUM> between which it is interposed. It is possible to use any type of deformable material to make the aforementioned thickness element <NUM>, or to provide an adhesive layer of greater thickness or a plurality of deformable layers sequentially superimposed on each other.

This thickness element <NUM> allows to define a surface of greater comfort for the user, as well as the spacing of the body mask <NUM> with respect to the nose in the portion adjacent to the same thickness element <NUM>.

According to alternative embodiments, not illustrated, it is possible to combine one or more characteristics of the embodiments described and/or illustrated, defining a facial hygiene mask in accordance with the present invention.

The manufacturing method of a facial hygiene mask <NUM> corresponds to the manufacturing method of a facial hygiene mask <NUM> according to the first embodiment, to which reference is made mutatis mutandis. Therefore, only the differences with respect to the manufacturing method of this first embodiment will be described in greater detail below.

In this case, the manufacturing method comprises the application phase carried out to arrange the adherence device at the upper edge <NUM>, but consisting of the thickness element <NUM> arranged on the inner portion <NUM> coupled to the body mask <NUM> and of the superimposed adherence band <NUM> to said thickness element <NUM>. This application phase can be carried out in two steps, by first coupling the thickness element <NUM> to the body mask <NUM> and subsequently superimposing the adherence band <NUM> on it, or in a single step, coupling to the body mask <NUM> a device consisting of the thickness element <NUM> and of the adhesion band <NUM> previously coupled.

<FIG> illustrates a schematic view of the facial hygiene mask <NUM> according to an example not according to the invention.

As shown in <FIG>, the facial hygiene mask <NUM> is of the surgical mask type, therefore the present example will be described below according to its characteristics, but the inventive concept can equally be applied to masks of different types, for example of the dust masks type.

All the aforesaid elements are visible in the first embodiment of <FIG> and, mutatis mutandis, found corresponding elements also in the example of <FIG>.

The folds <NUM> on the inner portion <NUM> of the facial hygiene mask <NUM> are folded in the vertical direction and, therefore, towards the face and eyes of the user. This arrangement of folds <NUM> can be problematic as the moisture in the air flow in the facial hygiene mask <NUM> can be directed upwards, or in the direction of the user's eyes where goggles and visors can be placed with consequent fogging.

The facial hygiene mask <NUM> according to the present example is therefore provided with an adherence device, consisting of an adherence band <NUM> arranged on the inner portion <NUM> at the upper edge <NUM>. This adhesion band <NUM> is provided with an adhesive surface <NUM>, in use in contact with the nose, and with a coupling surface, coupled to the body mask <NUM> and illustrated in greater detail in <FIG>. The contact and adhesion of the adhesive surface <NUM> to the user's nose are guaranteed by an adhesive with which the aforesaid adhesive surface <NUM> is provided.

The positioning of the adherence band <NUM> with respect to the body mask <NUM>, although this is defined as arranged on the inner portion <NUM> at the upper edge <NUM>, can be carried out in different ways, as below described but not illustrated. In the first embodiment illustrated therein, the adherence band <NUM> is coupled to the inner portion <NUM> of the body mask <NUM>.

On the other hand, the adherence band is coupled to the outer portion, and such the outer portion provided with the adherence band is folded over the inner portion. In this way, while being coupled with the outer portion, the adherence band is arranged at the inner portion, for coupling and sealing with the user's face portion, when in use.

Alternatively, the body mask comprises a pocket provided with an opening at the inner portion, and the adherence band is arranged inside the aforementioned pocket with the adhesive surface arranged at the opening.

In the embodiment illustrated and discussed therein, the adherence band <NUM> extends substantially along the entire upper edge <NUM>. In this way, ensuring the possibility of adhesion even to the portions of the face arranged laterally with respect to the user's nose.

Different sizes of the adhesion band are also possible for example by providing a reduced length extension with respect to the length extension of the upper edge.

The coupling of the facial hygiene mask <NUM> to the portion of the user's face, to cover the mouth and the nose portion, is achieved by means of a tie-on type system, which consists of four straps <NUM> which must be tied behind the head of the same user.

Different coupling possibilities are further possible, for example by means of elastic straps fastened behind the text or, more commonly, by means of ear loops, in which a cord is attached to the body mask <NUM> and is positioned behind the ears. Following the positioning of the aforementioned coupling elements to the user's face, the mask <NUM> is positioned in such a way as to ensure coupling with the portion of the face concerned. The solution envisaged in the present embodiment, i.e. the presence of the adherence band <NUM>, allows to correctly define and maintain the position of the facial hygiene mask <NUM>, in such a way as to allow the adhesion of the upper edge <NUM> to the nose without using of deformable metal elements. In particular, the adhesive provided on the adhesive surface <NUM> guarantees the impossibility of detaching the portion at the upper edge <NUM> of the body <NUM> of the mask, both during the mandibular movement and during the production of humidified air.

In this embodiment, the adhesion band <NUM> is provided with a covering element <NUM> arranged on the adhesive surface <NUM> adapted to preserve the adhesive before use.

The covering element <NUM> therefore guarantees a high lifecycle of the adhesion band <NUM>, making the adhesive available at the time of use.

The cover element <NUM> is also provided with a plurality of notches designed to divide the cover element <NUM> into a plurality of predefined cover portions <NUM> configured to define the size of the adhesive surface when removed. This solution, i.e. the presence of a plurality of covering portions <NUM>, allows to expose the portion of adhesive necessary for use according to the user's needs, according to the size of the portion of the face of the same, differentiating, for example, the application of the adhesive surface on the portion of the face of adults with respect to the same portion of the face of children.

The notches comprise at least one notch <NUM> substantially parallel to the upper edge <NUM>, adapted to reduce the transverse dimension of the adhesive surface with respect to the upper edge <NUM>. Furthermore, the notches comprise at least one pair of notches <NUM> substantially perpendicular to the upper edge <NUM> and arranged opposite and halfway from the center of the adhesive surface, adapted to reduce the longitudinal dimension of the adhesive surface with respect to the upper edge <NUM>. In this way, the arrangement of the notches <NUM>, <NUM> allows to define the width or thickness of the exposed adhesive surface.

According to alternative examples, not illustrated and not according to the invention, it is possible to provide a number, a size and a positioning of the notches different from what has been described and illustrated.

<FIG> illustrates a schematic view of the facial hygiene mask <NUM> according to another example not according to the invention, which corresponds to the facial hygiene mask <NUM> according to the third embodiment, illustrated in <FIG>, to which reference is made mutatis mutandis. Therefore, only the differences with respect to this first embodiment will be described in detail below.

The adhesion band <NUM> comprises a deformable thickness element <NUM> interposed between the adhesive surface <NUM> and the coupling surface <NUM>. The thickness element <NUM> is, therefore, capable of defining a thickness between the aforementioned surfaces <NUM>, <NUM> between which it is interposed. It is possible to use any type of deformable material to make the aforementioned thickness element <NUM>, or to provide an adhesive layer of greater thickness or a plurality of deformable layers sequentially superimposed on each other.

According to alternative embodiments, not illustrated, it is possible to combine one or more characteristics of the embodiments described and/or illustrated, defining a hygienic facial mask in accordance with the present invention.

The present invention therefore allows to define a facial hygiene mask capable of ensuring the tightness of the humidified air at the upper edge of the body mask.

In particular, the facial hygiene mask according to the present invention makes it possible to seal the humidified air without any modification to the technical capabilities of the mask itself, or to the composition of the layers or the materials of the layers.
