Description

A filter replaceable mask {Mask with Replaceable Filter}

The present invention relates to a filter replaceable mask.

The mask is configured to be worn on the face for the purpose of protecting the user's respiratory system from contaminated air. In recent years, dust masks or dust masks called fine dust masks have been widely used due to the increase of yellow sand or fine dust.

Generally, the mask is used to filter out fine dust, yellow dust or other harmful substances in the air entering the user's respirator. Therefore, various harmful substances remain in the mask used in the polluted air, and the used mask is used again after removing the harmful substances by discarding or washing.

Taking this into consideration, a mask for accommodating the filter in the mask, securing the accommodating space inside the mask body, and inserting / removing the filter into / from the accommodating space through the opening, However, the inner surface of the mask body is in contact with the user's nose and mouth, so that the problem of contamination of the inner surface of the mask body is not solved even if the filter is replaced.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

1 and 2, a mask 100 according to an embodiment of the present invention includes a mask body 110 and a hooking member 120 fixed to both side ends of the mask body. The mask body 110 is a portion covering the nose and mouth when worn by the user, and the strap 120 allows the mask body 110 to be held in close contact with the user's face as a part of the user's ear.

The mask body 110 is preferably made of cloth and has flexibility, but may be made of a material having various other characteristics. The mask body 110 has an outer surface 102 that is visible to the outside as the user wears the mask 100 and covers a portion of the user's face and a fastening surface 104 that is brought into contact against the user's face. The outer surface 102 and the inner surface 104 may be both side surfaces of the mask body 110 made of a single cloth or may be formed on both sides of the mask body 110 made of double or triple cloths formed by overlapping separate cloths It may be a surface. The mask body 110 may be generally oval in shape, as shown, or may be of any other suitable shape.

Since the outer surface 102 of the mask body 110 is exposed to the outside, it is more preferable that it has a design for enhancing the fashion sense. The outer surface 102 of the mask body 110 may also be made of black, blue, yellow, red, green, orange, or other enhancing aesthetic colors to enhance the fashion sense.

In the case where the mask body 110 is made of cloth, it is preferable that a vertical body sewing line 112 is formed on the upper and lower sides. The main body seam line 112 helps maintain the shape of the mask body 110 made of cloth in a three-dimensional manner. With this configuration, the user can have a sense of volume that can effectively cover the face contour including the nose and mouth. Thus, the surface 102 is convexly concave and the surface 104 is concave. Preferably, the main body seam line 112 is sewn on the inner side, that is, on the inner surface 104 side, so that the yarn used in the sewing and the cloth edge are not visible from the outer side, that is, from the outer surface 102 side.

Blades 130 extending inward from the edge along the upper and lower edges are formed on the surface 104 in the mask body 110, respectively. A wing 130 extending downward from the upper edge of the inner surface 104 is formed along the upper edge and a wing 130 extending upward from the lower edge of the inner surface 104 is formed along the lower edge do. The upper and lower wings 130 may be formed of the same material as the mask body 110, or may be manufactured using other materials. A detachable fastener 140 is attached to the wing 130 on the surface facing the user's face. The attachment / detachment fastener 140 is a portion in which a mask filter 200 described below is detachably attached to the mask body 110. Preferably, the detachable fastener 140 is a hook fastener (i.e., a so-called 'Velcro' fastener).

The detachable fastener 140 may be formed to have a sufficient length along the wing 130 so that the mask filter 200 can be sufficiently attached to the mask body 100. Preferably, the wings 130 are sufficiently long to extend at least one-half or more of the upper and lower edges of the mask body 110 and the detachment fastener 140 is sufficient to extend along the majority of the wings 130 It is good to have length. It is preferable that the detachable fastener 140 has a length sufficient to extend at least 1/2 of the upper and lower edges of the mask body 110.

In addition, the hook fastener material used in the detachable fastener 140 has a hook structure that is finer and has a smooth surface compared to conventional hook-and-loop fasteners, It is good to have a feeling of smoothness without feeling rough. It is also preferable that the detachable fastener 140 is made of a flexible plastic material and has a certain thickness so as to support the volume feeling of the mask body 110 from the inside of the mask body 110.

The fastener 140 for fastening and detaching may be sewn along the fastener seam 142 to the wings 130 of the mask body 110. [ The detachable fastener 140 may be attached to the wing 130 using an adhesive, thermal bonding, or the like, but it is more preferable that the chemical bonding agent, which may absorb harmful components through respiration of the user, is not used.

3 shows that the fastener 140 for fastening and detaching is fixed to a part (about one half of the area) of the wing 130 of the mask body 110. However, in order to improve the adhesiveness and esthetics, It is also preferable that the wing 130 of the mask body 110 is made wider so as to cover all or almost all of the wing 130. In this case, there is also provided an advantage that sewing can be performed simultaneously with the edge sewing finish of the mask body 110 without the need for a separate fastener seam 142. [

Figure 3 illustrates a mask filter 200 that may be used with a mask 100 in accordance with an embodiment of the present invention. The mask filter 200 is manufactured to have a size approximately equal to or slightly smaller than the overall shape of the mask body 110. When the user wears the mask 100 with the mask filter 200 attached thereto, the user's face such as the nose, mouth, or the like has a sufficient size to contact only the mask filter 200 without coming into direct contact with the mask 100 good.

The mask filter 200 may be fabricated in a disposable manner so as to be attached to the mask body 110 and then be detached therefrom. The mask filter 200 may be formed of a flexible filter cloth, a filter paper, or a filter paper to remove contaminants such as dust, As shown in FIG. Since the mask filter 200 is a portion directly contacting the skin, it is preferable that the mask filter 200 is made of a material having a milk component and a natural fiber component or a bamboo fiber rayon material. When it is made of a material having a milk component and a natural fiber component, it is preferably made of a material consisting of 10 to 30% of a milk component and 70 to 90% of a natural fiber, more preferably about 15 to 25% , 75 to 85% of natural fibers, and more preferably about 20% of milk components and about 80% of natural fibers. When manufactured from a bamboo fiber rayon material, it is preferable that the bamboo fiber rayon is 90% or more, and more preferably, bamboo fiber rayon is 100%. It is also possible to suitably combine these materials.

Upper and lower filter seam lines 202 may be formed on the upper and lower sides of the mask filter 200. The filter seam 202 helps maintain the shape of the mask filter 200 in three dimensions. With this configuration, the user can have a sense of volume that can effectively cover the face contour including the nose and mouth. Preferably, the filter seam 202 is sewn on the outside so that the yarn and cloth edges used for sewing are not visible on the inside, that is, on the side facing the user's face.

4 shows a state in which the mask filter 200 is attached to the mask 100 according to an embodiment of the present invention. The mask filter 200 is smoothly attached to and detached from the hook fastener 140 of the mask body 110. It is preferable that the mask fastener 140 of the mask body 110 is made to have a sufficient size so as not to touch the user's face in a state where the mask filter 200 is attached.

As shown in FIG. 3 or 4, a mask filter 200 specially designed to be particularly suitable for the mask body 110 according to an embodiment of the present invention may be used, and any disposable It is also possible to purchase a fine dust mask or a dust mask and use it as a mask filter.
