Background Art

In general, cooks or workers who work in the restaurants wear a mask in order to prevent the spit splashed from the mouth from falling down to foods or tableware, when they converse with each other or the others or make a sudden sneeze during cooking or distributing the foods.

However, most of the conventional masks are configured in a manner that a mouth screen made of cotton is hung around earflap of each ear via strings attached to and extended from both sides of the mouth screen to be fixed. As a result, if a wearer wears such a mask for long, the mouth screen closely attached to the mouth and nose becomes wet by the steam of breath, and thus a skin disease such as a blister or erythema is induced around the mouth. Also, in the case that a wearer wears a mask which is closely attached to the mouth and nose, he or she feels stuffy due to a difficulty in a normal breath. Also, in that case, since the lips cannot be moved naturally, it becomes difficult for a wearer to communicate with others.

Disclosure of the Invention To solve the above problems, it is an object of the present invention to provide a spit splash preventing mask including a mouth screen in which a filter material is detachably installed, a hairband shaped fixing unit for hanging the mouth screen around the earflap of each ear to fix the mouth screen, and a length adjustment unit and an angle adjustment unit which are installed on one side or both sides between the mouth screen and hairband shaped fixing unit, to thereby

make the mouth screen freely spaced from the mouth and angularly adjusted up and down, when wearing the mask.

Accordingly, the spit splash preventing mask according to the present invention enables cooks or workers who work in the restaurants to converse naturally with each other or customers at a state of wearing the mask. Also, the spit splashpreventingmask according to the present invention makes a wearer who wears the mask feel comfortable or convenienced even though he or she wears the mask for long. Also, in the case that cooks or workers make a conversation or a sudden sneeze during cooking or distribution of foods, spit splashed from the mouth is prevented from falling down on foods or tableware, to thereby effectively prevent various epidemics caused by the spit.

As shown in FIG. 1, a spit splash preventing mask includes a mouth screen 2 in which a filter material is detachably inserted, a length adjustment unit 23 which is installed in a hinged manner on one side or both sides of the mouth screen 2, an angle adjustment unit 24 which is installed in the end of the length adjustment unit 23, and a hairband shaped fixing unit 18 which is installed on one side of the angle adjustment unit 24.

As shown in FIG. 2, a mouth screen 2 which is installed in the spit splash preventing mask according to the present invention, includes a coupling protrusion or coupling protrusions 5 which are formed in one side or both sides thereof, and an elastic supporter 4 into which a filter material 6 made of antibiotic cotton cloth or paper, or sponge or a thin film is freely detachably inserted in the rear surface thereof.

As shown in FIG. 3, the elastic supporter 4 is integrally formed in the rear surface of the mouth screen 2 during injection molding of the mouth screen 2. Accordingly, the elastic supporter 4 is freely bent backwards during attachment or detachment of the filter material 6, and then restored in an original state by the elastic force thereof to then be pressed so that the inserted filter material 6 does not secede from the mouth screen 2.

As shown in FIGs. 2, 4A and 4B, a length adjustment unit 23 which is coupled with one side or both sides of the mouth screen 2, includes the slide 7 and a supporter 11 which are inserted into and coupled with each other. On one end of the slide 7 is formed a coupling hole 8 which is respectively coupled with the coupling protrusion or coupling protrusions 5 formed on one end or both ends of the mouth screen 2 and on the other end of the slide-7 is formed a stopper 10a, in which an insertion groove 9 having an unevenness portion 10 is formed inside.

On one end of the supporter 11 is formed a guide portion 12 which is inserted into the insertion groove 9 of the slide 7 and guided back and forth. In the end of the guide portion 12 are formed a stopper protrusion 13 subsequently coupled with the unevenness portion 10 to thus determine an inserted length of the guide portion 12 in the case that the guide portion 12 is inserted into the insertion groove 9 of the slide 7 and a stopper projection 14 which stops at the stopper portion 10a so that the supporter 11 inserted into the insertion groove 9 of the slide 7 does not secede from the insertion groove 9 of the slide 7.

As shown in FIGs. 5A and 5B, the angle adjustment unit 24 which is installed in the end of the length adjustment unit 23 includes a rotating plate 15 where a coupling hole 17 which is installed in the end of the supporter 11 of the length adjustment unit 23 is penetratively formed in the center thereof, and a stopper protrusion 16 is formed in one lateral surface thereof, and a fixing plate 20 where a coupling

protrusion 21 and a groove portion 22 which are respectively coupled with the coupling hole 17 and the stopper protrusion 16 of the rotating plate 15 are formed, in which the fixing plate 20 is integrally formed in one end or both ends of a hairband shaped fixing unit 18 which plays a role of hanging and fixing the mask around both the ears.

A method of using the spit splash preventing mask according to the present invention having the above-described configuration, and a functional relationship between the configurational elements will be described below.

In order to use a spit splash preventing mask according to the present invention, a user puts on a hair band shaped fixing unit 18 so as to be hung up around both the ears. Then, a rotating plate 15 in an angle adjustment unit 24 connected to a supporter 11 in a length adjustment unit 23 is made to rotate around a coupling protrusion 21 in a fixing plate 20 in the angle adjustment unit 24, so that a mouth screen 2 connected to a slide 7 in the length adjustment unit 23 is placed between the mouth and the nose. Here, since a stopper protrusion 16 in the rotating plate 15 is subsequently engaged with a groove portion 22 in the fixing plate 20, it is possible to minutely adjust an angle of the length adjustment unit 23, so that a minute angular adjustment can be performed.

Then, the slide 7 in the length adjustment unit 23 connected to the mouth screen 2 is moved back and forth so that the mouth screen 2 is adjusted to be spaced by a certain distance from the mouth. Here,

since a stopper protrusion 13 formed in a guide 12 of the supporter 11 is subsequently engaged with an unevenness portion 9 in the slide 7, it is possible to minutely adjust a length of the length adjustment unit 23, so that a minute lengthy adjustment can be performed.

Also, in the case that a filter material 6 inserted in the mouth screen 2 becomes dirty due to long-time wearing of the mask, an elastic supporter 4 in the mouth screen 2 is elastically pulled backwards, and then the dirty filter material 6 is taken out to replace the filter material 6 by a new one.

As described above, a mask for preventing spit from splashing, that is, a spit splash preventingmask according to the present invention is provided, which includes a mouth screen in which a filter material is detachably installed, a hairband shaped fixing unit for hanging the mouth screen around the earflap of each ear to fix the mouth screen, and a length adjustment unit and an angle adjustment unit which are installed on one side or both sides between the mouth screen and hairband shaped fixing unit, to thereby make the mouth screen freely spaced from the mouth and angularly adjusted up and down, when wearing the mask. Accordingly, the spit splash preventing mask enables cooks or workers who work in the restaurants to converse naturally with each other or customers at a state of wearing the mask. Also, the spit splash preventing mask makes a wearer who wears the mask feel comfortable or convenienced even though he or she wears the mask for long. Also, in the case that cooks or workers make a conversation or a sudden sneeze

during cooking or distribution of foods, spit splashed from the mouth is prevented from falling down on foods or tableware, to thereby effectively prevent various epidemics caused by the spit.

Industrial Applicability As described above, the spit splash preventing mask according to the present invention can be used for cooks or employees working in the kitchens or restaurants, or doctors or nurses working in hospitals.
