Abstract

The "Mask" is a protective device for both the respiratory tract from micro-dust or bacteria and viruses in the air intake phase, to avoid being contaminated and not to contaminate the external environment by emitting air, potentially infected droplets. The main features are the high degree of tightness of the filter, interchangeability, good sanitation management, portability with less harmful effects on the skin, quick replacement and the opportunity to recycle the filter with polymer sanitization.

Description

DESCRIPTION OF INDUSTRIAL INVENTION

With the title: "Mask with interchangeable fabric".

TECHNICAL FIELD

The present invention refers to a "Mask", suitable for effective protection from dust, micro-dust, bacteria, viruses and more, which must ensure the best service, offering easy replacement of the single or multi-filtering part, thanks to its fixing by means of a metal core inside a frame, which also allows an excellent fit on the close-fitting part of the face, even if obtained with light pressure on the skin.

The frame can be sanitized with specific products, and is coated with a nanolayer of a metal that has the characteristics of self-sanitizing in particular from viruses in a few hours.

This particularity and others highlighted for specific applications of the "Mask", can be clearly seen, thanks to a rapid interchangeability of the filtering part, as well as the easy cleaning of the support and service parts, namely:

- the external frame, light, delicate, soft, with nails or closing tabs; - the metal insert;

- the elastic tapes.

Another peculiarity of this "Mask" as a non-limiting example, is noted for uses, where it is necessary to keep the protective fabric in perfect working order and especially where it is easily washable and interchangeable in the eventuality. Particularities obtainable with the "Mask" object of the present invention, widely used in other applications, where a high protective control of microbiological particles is required. BACKGROUND ART

It is known that in the state of the art there are various types of protective articles but they do not allow the accurate cleaning of the fabric and in particular the easy interchangeability and replacement of the fabric which acts as a filter, in addition to the self-sanitization of the frame and the elastic ribbons.

The effective use of the common mask is evidenced by the almost impossibility of interchanging and cleaning the protective element as it is an integral part of itself; moreover, even the most sophisticated ones find it difficult to guarantee fit with perfect adherence to the surface of the face.

This disadvantage is overcome very well with the "Mask" object of the invention of the present invention.

Mainly these limits have been eliminated with the "Mask" object of the present invention, with the assembly of a few simple but functional elements.

The first object of the present invention is to provide a micro-particle protection "Mask" which, thanks to its easy interchangeability, ensures service in any environment of use and which is reliable. The second purpose of the invention is to create a "Mask" of simple manufacture of its main components where:

- the frame is the seat for locking the fabric / felt by means of centering holes with pressure nails / tabs;

- the fabric / felt is the filtering part and has the shape of a shaped cup, which ensures the largest transpiration surface; - a metal insert blocks the closed fabric / felt with slight pressure in a cavity created in the frame section.

The third purpose of the invention is to create a "Mask" which, thanks to the simplicity of manufacturing its components, where the frame is light and the contact surface; delicate, adherent, soft, porous, and not breathable.

The fourth purpose of the invention is to create a "Mask" where the indifferent filter / felt can be fabric, non-woven fabric, other with specific functions.

The fifth purpose of the invention is to create a "Mask" where the frame is light, delicate, soft, with pressure closing nails. The sixth purpose of the invention is to create a "Mask" where the frame, thanks to the appropriate profile of the contact section and its practical use, allows normal perspiration, avoiding sweating and annoying developments of evaporations of various kinds.

A further purpose of the invention is to provide a "Mask", which mainly allows its use in an easy way, and at the same time to offer the best relief to the person and perform his service in the best possible way.

DISCLOSURE OF INVENTION

Summary of the invention

These and other purposes are achieved in accordance with the present invention, by means of a "template", where the answer for each service is possible in a simple and rapid way, by assembling the main elements that make it up and better identified below.

One of its embodiments; figure (b-c): 1) Frame;

2) Filter;

3) the metal insert;

4) the elastic tape. The filter (2) rests on the frame (1), and the insert (3) blocks the filter (2) through the pressure tab. Other service details complete the assembly.

Additional advantageous aspects.

Further advantageous aspects of the "Mask" of the present invention are set out in the dependent claims. Then using the "Mask" with the possibility of cleaning and interchangeability of the fabric, protection filter, always keeping its main structure, the best use is obtained compared to those obtainable through the known art.

Furthermore, the invention has a simple manufacturing structure and provides for the correct exchange of the inspired and expired air by means of direct self-ventilation, with the right protection from dangerous microparticles.

Furthermore, in an advantageous aspect of the present invention, it has the possibility that the "Mask", thanks to its easy interchangeability of the fabric, allows to have a perfect efficiency of the protection which allows an optimal use, as well as containing the operating costs of the service. .

Brief description of the figures The characteristics and advantages of the present invention will be highlighted by the following description of a practical embodiment thereof, illustrated by way of non-limiting example, partially represented by the accompanying provisional drawings, in which:

Figure (a) represents a typical mask according to the known art; where the protection is a fabric, or non-woven fabric, mono or multilayer, of suitable shape.

Figure (b-c) represents a typical practical embodiment of the invention, where the fabric, or non- woven fabric, all also mono or multilayer, and of suitable shape, but interchangeable.

Detailed description of the invention

Figure (a) represents a typical mask according to the known art; the protection filter is made with a shape of suitable section, cut only or cut and sewn of various shapes, of fabric or non-woven, single or multilayer which is then used.

Figure (b-c) represents a typical practical embodiment of the invention, where the "Mask" is made by means of a frame (1), which supports the easily interchangeable protection filter (2).

A template, according to the known art, is shown in figure (a), according to a typical scheme which includes:
