Korean Utility 20-0386879, US Patent 4,090,510

As air pollution increases in the 20th century, the importance of masks to protect the respiratory organs from air pollution increases, and various types of masks are being developed.

If the masks currently used are classified by type,

First, there is a bar-shaped mask manufactured by sewing a fabric. The bar-type mask is made of a cloth fabric, so wearing comfort and good breathability, but usually has a problem of poor filter capacity. However, it is possible to use it for a long time because it can be washed, and there is good contact with the face as a cloth material, and skin trouble does not occur.

On the other hand, the product with enhanced dustproof function is an industrial mask made of nonwoven fabrics. Although these industrial masks have a strong filter function, there are many inconveniences for the general public because they are restricted in materials, shapes, and manufacturing methods to enhance the filtering ability. .

On the other hand, as a product complementing the advantages of the bar mask and the industrial non-woven mask has been developed a product that inserts a filter inside the bar mask.

Such products include a mask inserted into the upper or side surface of the mask as shown in Korean Utility Model No. 20-0386879 and blocked with a support device such as a bellows. However, these masks are made of bag closures such as bellows and buttons, which makes the outer part of the mask untidy. It becomes hard to wear down, and when a thick filter is inserted into the pocket, the mask is thick, and when the mask is worn, a problem arises that the side surface of the mask is lifted up. In addition, since the mask is wrapped around the outside of the filter, the filter is not in close contact with the human body, and thus there is a problem that the filtering function is weakened.

Meanwhile, the filter insertion method shown in US Pat. No. 4,090,510 is a method of overlapping a mask and a filter body and fixing it with a clip. This method does not need to use a filter, that is, when a filter is removed when a dustproof function is not needed. There is a problem that it becomes difficult to use a mask because of the clip.

In the present invention, it is configured so that the filter can be easily detached to the general face mask and there is no deformation in the shape of the mask even when wearing the filter, the filter adheres well to the face, even if you wear a mask without inserting the filter at all We want to provide a filter insert mask that doesn't exist.

In the mask of the present invention, as shown in FIGS. 1 and 2, a mask body including a mask outer portion 10 forming an outer surface of the mask, a mask inner portion 20, and an edge portion 30 surrounding the mask portion ( 1) and a string portion 40 provided at both ends 2a and 2b of the mask body, and the pocket portion 60 is formed in the inner portion 20 of the mask so that the filter 50 can be inserted. It features. Hereinafter, the present invention will be described by way of examples.

The outer mask 10 forming the outer surface of the mask of the mask of the present invention is resistant to sunlight, and has a static density so that inflow of dust and the like can be blocked to some extent, and a material having elasticity is used. In addition, depending on the purpose, a material that absorbs ultraviolet rays may be used.

The mask inside 20 has a dust blocking effect, but also has a proper maturity, and in particular, selects and uses a material that does not cause trouble when in contact with the face.

The edge portion 30 surrounding the mask is made of a material that does not absorb dust or dirt while having elasticity.

The string portion 40 provided at both ends 2a and 2b of the mask body is made of a material having elasticity and soft and trouble-free contact with the body.

The filter element 50 inserted into the inside of the mask 20 preferably uses a wet filter or at least a correction filter having a low dust resistance and excellent dustproof function. Furthermore, the overlapping portion 51 generated by sewing or bonding is formed in the central portion of the filter used in the present invention so that the overlapping portion performs the function of the frame body. That is, the frame portion is also important for forming the shape of the mask, but in order to prevent the filter body from being drawn toward the mouth when the mask user inhales air, the role of the frame body to maintain the shape of the filter body is very important.

As shown in FIG. 3, the filter body is generally configured in such a way that the nonwoven fabric 57 and the span bond 59 are wrapped around the electrostatic filter 58. As shown in FIG.

On the other hand, the filter body 50 used in the mask of the present invention is manufactured by sealing or bonding the ends of the two filters so that they overlap each other, so that the overlapping portion 51 is formed in the center of the mask to form a frame of the mask. In the center of the filter element, the main filter part 52 which performs most of the filter function and the inserting part 53 are formed on both sides of the main filter part 52 so that the filter can be inserted into the bag portion of the mask. do.

Furthermore, in the filter of the present invention, when the filter is mounted on the mask by forming a catching groove 54 in which the width of the filter portion is narrowed or widened between the main filter portion 52 and the inserting portion 53, the catching groove portion 54 is formed. It is formed to be fixed to the locking jaw portion 61 formed in the mask bag portion, it is characterized in that the filter is inserted after the mask, so as not to be separated.

  The inside of the mask 20 has pockets 60 formed on both side surfaces of the mask except for the center portion so that the filter 50 can be inserted therein. As shown in FIG. 2, the pocket part 60 is attached to both sides of the mask with a size slightly larger than that of the mask inner surface, and the insertion part 53 of the filter is inserted and fixed to the pocket part.

 Further, the inside of the pocket portion 60 of the present invention is provided with a locking jaw portion 61 is reduced in width of the pocket portion is inserted into the filter body 50 is coupled to the engaging groove 54 of the filter body filter body 50 Secure it firmly.

In addition, in the present invention, a mesh or other elastic material is inserted into the inner edge portions 62a and 62b of the pocket portion so that the edge portions 62a and 62b are not wrinkled or rolled up. Both ends (2a, 2b) of the mask body of the present invention is provided with a string portion 40 is provided so that the mask body can be fixed to the face by hanging the mask body on the ear. ) Is installed so that the length of the string can be adjusted, and when the string is shortened, the string fixing means 42 is installed at the end of the string to prevent the end of the string from being caught. The strap fixing means is preferably in such a manner as to attach an annular guider to the end of the strap.

4 is a view showing a state where a mask and a filter of the present invention are inserted.

The mask of the present invention, by installing the filter insertion fork on both sides of the mask, it is possible to freely insert the filter 50 into the mask simply by inserting the filter in the pocket without a separate attachment such as a hook or Velcro. Also, because the forge is located on both sides of the mask, both sides of the filter are not only fixed naturally, but also the filter and the mask are not fixed through the fastening means such as Velcro or button, but the position of the filter is inserted into the mask. Therefore, since the slippage occurs between the mask and the filter, even if you have a conversation or move the mouth while wearing the mask, the resistance to movement of the mouth in the worn state is reduced because only the filter moves without significant deformation outside the mask. Discomfort due to wearing the mask is reduced, and the center portion of the mask is relatively thin because there is no pocket attached, so when the filter is not attached, the supply resistance of the mask is considerably low, and the center portion is thin and the side portion is Is thicker so that the center part is separated from the face due to the difference in thickness Caused by a facial mask, body therefore reach the front is improved wear masks.

Thus, the mask of the present invention is formed in a structure that can easily remove the filter on the normal face mask, there is no deformation in the mask shape even when wearing the filter, the filter is in close contact with the face, wearing the mask without inserting the filter It is a useful filter insert mask with little inconvenience.
