Description

Mask {MASK}

The present disclosure relates to a mask capable of protecting the respiratory system of the face from particulate harmful substances such as dust and fine dust.

Various masks have been proposed to mask the respiratory system of the face for the purpose of preventing cold, dust, or infection. These masks are designed and manufactured to meet the purpose of use, such as a cold room, a surgical mask, a sulfur mask (or a health mask), a mask for protection, and an industrial mask. For example, the sulfur-using mask includes a main body capable of covering the nose and mouth, and an annular ring made of a string that can be fixed to the ear or head to fix the main body to the face. Such a sulfur-using mask is provided with a filter layer in the main body portion, so that particulate harmful substances such as yellow dust and fine dust contained in the air can be filtered out.

The above-mentioned sulfur-use mask is a product which must be approved by the Korea Food and Drug Administration (hereinafter simply referred to as the "Food and Drug Administration") and has a performance different from that of industrial products such as a winter booth. With regard to the performance of the sulfur-using mask, the pharmacy department is required to satisfy all of the main items of collection efficiency, face leakage rate, and face air intake resistance.

However, in order to satisfy the performance-related main items required by the place of drug disposal, conventional sulfur-use masks are designed and manufactured only in the shape of a folded-up or cup-shaped shape and are commercially available. That is, since the degree of adhesion of the mask to the face portion is low in a flat plate shape (or flat plate wrinkle shape) that can be spread in a three-dimensional form when worn like a surgical mask, the main items required by the place of drug delivery, And for this reason, it was not adopted in the form of a sulfur-using mask.

SUMMARY OF THE INVENTION [0006] The present invention provides a mask that has a flat wrinkle shape and satisfies the performance of a sulfur-using mask required by a dissolution site.

The present disclosure provides embodiments of a mask that shields the face of a respiratory tract. The mask according to an exemplary embodiment includes a body portion including a shell layer, an endothelial layer, and a filter layer interposed between the shell layer and the endothelial layer; a ring attached to both sides of the body portion in the transverse direction; And a skin contact layer made of a stretchable material having pores formed therein. In this embodiment, the body portion is provided with a plurality of pleats which are foldably extendable in the longitudinal direction. At least a part of the respirator is inserted into a space formed between the endothelial layer and the skin-contacting layer through the hole, and the skin-contact layer is stretched and contracted to form a face- Respectively.

In one embodiment, the skin contact layer is formed of a stretchable material having a tensile elongation in the transverse direction of 65% or more and a tensile elongation in the longitudinal direction of 140% or more.

In one embodiment, the filter layer is formed of a material having a basis weight of 25 gsm or more.

In one embodiment, the annulus includes a pair of earring straps attached to the shell layer.

In one embodiment, the mask further comprises a nacelle attached to the endothelial layer facing the skin contact layer. In addition to these embodiments, the mask may further include a co-sponge attached to the endothelial layer and provided between the endothelial layer and the skin contact layer to cover at least a portion of the nose.

In one embodiment, the main body portion includes a shape retaining portion that is divided by a plurality of corrugations, at least one upper side development portion in which the lower side portion is partially folded successively from the shape retaining portion, And one lower deployment portion.

In one embodiment, the collecting collection efficiency is greater than 80%, the facial inspiratory resistance is less than 60Pa, and the facial portion leakage rate is less than 25%.

The mask according to the embodiments of the present disclosure includes a body portion having a flat wrinkle shape before wearing and a skin contact layer attached to the body portion. Such a mask can easily be changed into a three-dimensional shape by an improved wrinkle structure of the main body when worn. The skin contact layer forms a space for inserting a part of the respiratory part of the face part together with the body part. The skin contact layer is formed of a stretchable material which can be adhered to the face part, so that air leakage can be minimized. The nose and mouth can be inserted into the space formed inside the body portion through the hole formed in the skin contact layer in a state in which the vicinity of the respiratory surface of the face portion is in close contact with the skin contact layer. In this wearing method, the inconvenience that the nose and the mouth come into contact with the mask is minimized, and the wearing feeling of the mask can be improved. Although the mask according to the embodiments has a flat plate shape, it may be provided in the form of a sandy mask together with a contact type or a cup shape. In this case, by changing the shape of the mask in accordance with the needs of various consumers, It has the effect of widening the width.

The mask 100 may further include an annular portion 130 attached to both sides of the main body 110 in the lateral direction (X direction). In one embodiment, the ring 130 includes a pair of earrings 131 that can be worn on the wearer's double ear when the mask 100 is worn. The ring portion 130 is not limited to the pair of earring straps 131 but may include, for example, a head strap that can be hooked or tied to the head. The earring strap 131 is attached to the main body 110 so as to have an annular shape. The mask 100 is attached to the face 10 by a pair of earring straps 131 when the mask 100 is worn. In this embodiment, the earring straps 131 are attached to the outer surface of the outer layer 111, In this case, the mask 100 is prevented from floating around the ball and the ear area of the face portion 10, so that the mask 100 is brought into close contact with the face portion 10.

In the mask 100, the main body 110 has a structure in which the filter layer 112 is interposed between the outer skin layer 111 and the inner skin layer 113. The skin layer 111, the filter layer 112 and the endothelial layer 113 constituting the body 110 have a rectangular shape or the like and the edges may be abutted against each other and pressed together by an ultrasonic bonding method or the like. Particulate harmful substances such as dust and fine dust contained in the air are filtered through the outer skin layer 111, the filter layer 112 and the endothelial layer 112 in order. The main body 110 has a plurality of corrugations L so that the mask 100 can be folded and folded in the longitudinal direction (Y direction) when the mask 100 is worn.

The main body 110 is formed of a nonwoven fabric. In particular, the filter layer 112 is formed of a nonwoven fabric manufactured by a melt blown method, and is formed of an electrostatic filter capable of filtering harmful substances. The skin contact layer 120 can be referred to as a tight cloth and is formed of a stretchable nonwoven material. The skin contact layer 120 may be formed of a material containing polypropylene or polyethylene so as to have elasticity.

The skin contact layer 120 has a shape corresponding to the body portion 110. The skin contact layer 120 has an edge bonded to the endothelial layer 113 of the body portion 110. A hole H is formed in a central portion of the skin contact layer 120 so that the space S is formed in the space S between the body 110 and the skin contact layer 120 So that the nose 1 and the mouth 2 can be inserted. In one embodiment, the hole H is formed to have an elliptical shape or a similar shape whose length in the lateral direction (X direction) is longer than the length in the longitudinal direction (Y direction), and the nose portion 1 is inserted And a part of the upper edge of the vertical direction (Y direction) has an expanded shape.

As shown in FIGS. 4 to 6, when the mask 100 is worn, a plurality of wrinkles L are spread, and the main body 110 having a flat plate shape before being worn is deformed into a three-dimensional shape. In the mask 100, a space S is formed between the main body 110 and the skin-contact layer 120, and at least a part of the respirator (that is, the skin- The nose 1 and a part of the mouth 2). The skin contact layer 120 is positioned behind the mask 100 deformed in a three-dimensional shape, and can be stretched or shrunk in conformity with the outline shape of the face portion 10 to be brought into close contact with the face portion 10. It can be understood that the skin contact layer 120 in the present disclosure is " adhered " to include all of partially or wholly adhered to the face portion 10.

The mask 100 of one embodiment is provided with a nose piece 140 for preventing the mask 100 from being sagged or peeled by allowing the mask 100 to be caught on the nose 1 of the wearer and for bringing the mask 100 into close contact with the nose portion, As shown in FIG. The nose 140 may be attached to the body portion 110 and attached to the inner surface of the endothelial layer 113 facing the skin contact layer 120, for example.

7 and 8, the mask 100 may further include a co-sponge 150 attached to the endothelial layer 113 to cover some or all of the co- The co-sponge 150 is provided between the endothelial layer 113 and the skin-contact layer 120 and contacts the nose 1 when the mask 100 is worn. Such a co-sponge 150 is made of a cushion material to improve comfort and minimize leakage of air around the nose 1.

Referring to FIG. 6, the mask 100 has an improved wrinkle structure to facilitate spreading and folding in the main body 110. The main body 110 may be divided into a shape holding portion 110a, at least one upper side developing portion 110b and at least one lower side developing portion 110c by a plurality of corrugations L. The shape retaining portion 110a serves as a reference when deforming the body portion 110 into a three-dimensional shape. The upper spreading portion 110b is formed by partially folding the lower portion sequentially from the shape holding portion 110a. In addition, the lower side deploying portion 110c is formed by partially folding the upper portion sequentially from the shape retaining portion 110a. In one embodiment, the mask 100 has a five-fold pleat structure and is configured to include three upper side deployments 110b and two lower side deployments 110c. The number of the corrugations L formed in the main body 110 is not limited to the number of corrugations L in the embodiment, and may be three corrugations or four corrugations or may be formed by six or more corrugations .

Hereinafter, the performance of the mask 100 that satisfies the main items of the sulfur-used mask required by the destination of dissolution will be described. In terms of performance of sulfur-using mask, the major items required by the pharmacy are facial leakage rate, dust collection efficiency, facial air inspiration resistance, face leakage rate of less than 25%, bulk collection efficiency of more than 80% Which is required for the performance of the sulfur-using mask.

Table 1 shows the experimental data of each product of the mask with respect to the leakage rate of the face portion. To obtain the experimental data in Table 1, a respiratory protection tightness tester (e.g., TSI 8038 instrument from TSI) was used. In Table 1, Example 1 is a mask having a skin contact layer 120 made of a stretchable material, Example 2 is a mask test sample having a skin contact layer 120 made of a stretchable material, and a co- . In addition, Comparative Example 1 shows a sample of a general planar mask without the skin contact layer 120 and the co-sponge 150.

In Table 1, the Fit Factor indicates the degree to which the mask is in close contact with the face portion, and the larger the fitment factor, the higher the degree of contact. In addition, the leakage rate (IL) indicates the degree of leakage of air between the mask and the face portion, and the total leakage rate (Total Inward Leakage: TIL) indicates leakage of air from the main body 110, Of the total leak rate. As shown in Table 1, in Examples 1 and 2, the total leakage rate was measured as 12% and 10.5%, respectively, and the condition of the face leakage rate required by the hospital is less than 25%. On the contrary, Comparative Example 1 does not satisfy the condition that the total leakage rate is measured as 60% and the leakage rate of the face portion required by the hospital is less than 25%. That is, the general flat-plate type mask can not satisfy the condition of the leakage rate of the face portion of the sulfur-using mask required by the disinfecting destination.

Table 2 shows experimental data relating to the elasticity of the skin contact layer 120 used in the mask 100 of one embodiment.

division Tensile elongation (transverse direction) Tensile elongation (longitudinal direction) Elastic material 65% to 80% 140% to 170% Non-stretchable material 55% to 65% 35% to 50%

In one embodiment, a skin contact layer (not shown) formed of a stretchable material having a tensile elongation to a Mask Machine Direction (MD) of 65% or more and a tensile elongation to a longitudinal direction (Mask Cross Direction; CD) 120 are provided on the mask 100. When the tensile elongation in the transverse direction (for example, the X direction in FIG. 1) of the skin contact layer 120 is less than 65% and the tensile elongation in the longitudinal direction (for example, the Y direction in FIG. 1) is less than 140% The skin contact layer 120 does not smoothly stretch or shrink along the contour of the face portion 10 when the mask 100 is worn and the skin contact layer 120 is not brought into close contact with the face portion 10, And the face portion 10 can be formed with a gap through which air can leak.

Table 3 shows experimental data of the material of the mask with respect to the leakage rate of the face portion. That is, Table 3 shows experimental data relating to the leakage of the face portion when the skin contact layer 120 is formed of a stretchable material and when the skin contact layer 120 is formed of a non-stretchable material. In order to obtain the experimental data of Table 3, respiratory protection tightness tester as shown in Table 1 was used. In Table 3, Example 1 shows a mask sample with a skin contact layer 120 of a stretchable material, Example 2 shows a mask sample with a skin contact layer 120 of an elastic material and a co-sponge 150, respectively . Comparative Example 1 shows a mask sample having a skin-contact layer of a non-stretchable material and not having a co-sponge 150.

As can be seen in Table 3, in Examples 1 and 2, the total leakage rate was measured as 12% and 10.5%, respectively, and satisfied the condition of the facial leakage rate of the plant. However, in the case of a mask not provided with the co-sponge 150, a skin contact layer made of a non-stretchable material is provided as in Comparative Example 1, and the mask is not in close contact with the face portion 10 as compared with Embodiments 1 and 2, Leakage rate is measured as high as 20 ~ 30%. In this case, the condition of the facial portion leakage rate of the destination can not be satisfied, and the mask of Comparative Example 1 does not satisfy the performance as a sulfur-using mask.

As shown in Table 1, in Table 3, it can be seen that the total leakage rate is small when the mask is provided with the cohesion 150 in addition to the skin contact layer 120 made of a stretchable material.

Table 4 shows the experimental data of the mask related to the collection efficiency. Specifically, Table 4 shows experimental data relating to the filter layer of the mask. The experimental data in Table 4 are data obtained by measuring with a collection efficiency tester (for example, TSI 8130 instrument of TSI, experiment under the condition of NaCl 95LPM). Comparative Example 1 shows a mask sample with a filter layer having a basis weight of 20 gsm, Example 1 shows a mask sample with a filter layer having a basis weight of 25 gsm, Example 2 shows a mask with a filter layer having a basis weight of 40 gsm, Samples are shown.

As shown in Table 4, when the filter layer 112 provided in the main body 110 has a basis weight of 20 gsm, the filtration efficiency is measured to be less than 80%. In the case where the filter layer 112 provided in the main body 110 has a basis weight of 25 gsm and 40 gsm, the collecting collecting efficiency is measured in excess of 80%. In one embodiment, the filter layer 112 is formed of a material having a basis weight of 25 gsm or more to stably satisfy a condition exceeding 80% of the collecting efficiency required by the destination.

Table 5 shows the experimental data of each product of the mask in relation to the collection efficiency. The experimental data in Table 5 were measured using a collecting efficiency tester as shown in Table 4. In Table 5, Example 1 shows a mask having a skin contact layer 120 made of a stretchable material, Example 2 shows a mask having a skin contact layer 120 made of a stretchable material, and a co-sponge 150. In addition, Comparative Example 1 shows a general planar mask without the skin contact layer 120 and the co-sponge 150.

As can be seen in Table 5, in Examples 1 and 2, the efficiency of collecting collecting was measured to be 98.4%, which satisfies the condition that the collecting efficiency required by the destination is 80% or more. On the other hand, in Comparative Example 1, the efficiency of collecting collecting was measured to be 65.3%, and thus the condition of collecting collecting efficiency required by the receiving place is not satisfied. That is, a general flat plate type mask can not satisfy the collection efficiency of collecting more than 80%.

Table 6 shows experimental data of each product of the mask with respect to the intake air resistance of the face. The experimental data in Table 1 are data obtained by measuring with an intake resistance tester (30 LPM condition). Example 1 shows a mask having a skin contact layer 120 of a stretchable material, Example 2 shows a mask having a skin contact layer 120 of a stretchable material and a co-sponge 150, respectively.

division Intake resistance Face suction resistance
(Based on the pharmacy) Remarks Example 1 19.6 Pa Satisfies below 60 Pa Skin-contact layer with elastic material Example 2 20.6 Pa Satisfies below 60 Pa Stretchable skin-contact layer and co-sponge

Referring to Table 6, in Examples 1 and 2, the intake resistance was measured to be less than 60 Pa. That is, in the case of the face air intake resistance among the main items of the sulfur-using mask, it is confirmed that the skin contact layer 120 having at least a stretchable material can satisfy the criteria regardless of the presence or absence of the co-sponge 150.

Through such experiments, it can be confirmed that the mask 100 according to the embodiment satisfies all of the main items of the sulfur mask required by the sink. That is, the mask 100 satisfies a facial portion leakage rate of less than 25%, a collecting collection efficiency of more than 80%, and a face air intake resistance of less than 60Pa. The mask 100 of the embodiment is in the form of a flat plate before being worn, but has a skin contact layer 120 of a stretchable material touching the skin. Therefore, unlike a general planar mask, the mask 100 has a structure for minimizing leakage of air, Which is required by the present invention. Such a mask can be manufactured by designing as a form of a sulfur-using mask.
