Description

  The present invention relates to a mask that is excellent in moisturizing properties, hardly feels stuffy and annoying even when worn for a long time, and is suitable for long-time wearing indoors.

  The purpose of wearing the mask is to prevent foreign substances such as bacteria, viruses, pollen, mold, and dust floating in the atmosphere from entering the body and to prevent drying of the nose and throat.

  Conventional masks employ a method of arranging a collection filter inside the mask body or laminating materials to obtain a filter effect for the purpose of preventing foreign matter from entering the body. For example, in the case of a non-woven fabric type mask, a collection filter is arranged between the non-woven fabric on the outside air side and the non-woven fabric on the mouth side. In the case of a gauze type mask, usually 10 or more sheets of gauze are laminated or less. A collection filter is placed between the gauze.

  Although these masks have a great effect of preventing foreign substances in the air from entering the body, the filter effect becomes an obstacle when inhaling the air, and when wearing the mask for a long time, the wearer often feels short of breath It can be seen.

Therefore, in order to eliminate the difficulty of breathing when wearing the mask, a mask that makes the part of the mask body in contact with the nose thinner or rougher than the part in contact with the mouth to make breathing through the nose easier. It has been proposed (Patent Document 1 and Patent Document 2). There are various types of masks intended to prevent drying of the nose and throat. For example, a mask in which a water retention sheet and a moisture retention sheet are arranged on the mask body has been proposed (Patent Document 3).
JP-A-8-215325 Registered Utility Model No. 3118375 JP 2003-62098 A

  However, Patent Document 1 and Patent Document 2 aiming to eliminate the difficulty of breathing at the time of wearing the mask also have a portion that abuts the mouth is thicker than a portion that abuts the nose. It cannot be said that it can be solved. In addition, Patent Document 3, which is intended to prevent the drying of the nose and throat, also includes a collection filter in addition to the water retaining sheet and the moisture retaining sheet in the mask body, so that it is difficult to breathe when the mask is worn for a long time. It will make you feel.

  Masks may be worn both outdoors and indoors, but for those who wear masks for the purpose of moisturizing the mask in a room where there are relatively few foreign objects in the atmosphere, even if they are worn for a long time, they will not be breathable. Although a mask that does not feel is desired, none of the conventional masks satisfy these requirements.

  The present invention has been made in view of the above points, and is a mask suitable for wearing indoors for a long time, having excellent moisture retention, and making the wearer feel almost uncomfortable and annoying even when worn for a long time. The purpose is to provide.

  The mask according to claim 1 is formed of a main body forming member made of one gauze or two to five laminated gauze, and covers a mask main body that covers a wearer's nose and mouth, and a side of the mask main body. Provided at both ends in the direction, and provided with an ear-hanging body that is hung on a wearer's ear, and the mask body has a plurality of folded portions that are folded so as to have a substantially S-shaped cross-sectional side view, The plurality of folding parts include a first folding part having a length equal to the lateral length of the mask body, and a second folding part having a length equal to or less than half of the lateral length of the mask body. It is comprised by these.

The mask according to claim 2 is the mask according to claim 1, wherein the main body forming member is one sheet in which at least one of the longitudinal and lateral threads is 20 or more, and the other is 26 or more per 1 cm ^2. It consists of gauze.

  According to a third aspect of the present invention, in the mask according to the first or second aspect, the longitudinal length of the main body forming member is 200 to 300 mm.

  According to a fourth aspect of the present invention, in the mask according to any one of the first to third aspects, the ear hanger is formed of a string member having a diameter of 0.25 to 2 mm.

  The mask according to claim 5 is the mask according to any one of claims 1 to 4, wherein the first folding portion is located at a longitudinal center portion and both longitudinal sides of the mask body, and the second folding portion. Is located between the adjacent first folds and on both lateral sides of the mask body.

  The mask according to claim 6 is the mask according to any one of claims 1 to 4, wherein the first folding portion is located only in a longitudinal center portion of the mask body, and the second folding portion is the mask. Between the longitudinal end of the main body and the first fold part and between the longitudinal other end of the mask body and the first fold part, and located at both lateral ends of the mask body, The length of the second folding part is longer as it is located on the first folding part side.

  According to the first aspect of the present invention, the mask main body formed of the main body forming member made of one gauze or two to five laminated gauze is folded so that the cross section in a side view is substantially S-shaped. A plurality of folding parts, the first folding part having the same length as the lateral length of the mask body and a length less than half of the lateral length of the mask body. Since it is comprised by the 2nd folding part which has thickness, when a folding part is expanded, it will solidify so that a mask main body may draw a dome-shaped curved surface.

  In addition, a moderate space is formed between the mask body and the wearer's mouth, the mask body does not cling to the wearer's mouth, and the wearer feels almost uncomfortable and annoying even after wearing for a long time. I won't let you. Moreover, since moisture is appropriately held by natural fibers of gauze and the like, it is excellent in moisture retention and can be prevented from drying of the nose and throat by the held moisture, which is suitable for prevention and treatment of colds. Furthermore, since the mask body is lightweight and has good air permeability, it can be worn with a relaxed feeling for a long time and is suitable for wearing indoors for a long time.

According to the invention of claim 2, since the main body forming member is composed of one gauze in which either one of the longitudinal and lateral threads is 20 or more and the other is 26 or more per 1 cm ² , the mask The humidity of the space between the main body and the wearer's mouth can be maintained at about 80%, a mask body with good moisture retention can be formed, and the air permeability and extremely light weight make it bothersome when wearing. Is reduced.

  According to the invention which concerns on Claim 3, since the vertical direction length of a main body formation member is 200-300 mm, a relaxed three-dimensional mask can be formed.

  According to the invention according to claim 4, since the ear hanger is formed of a string member having a diameter of 0.25 to 2 mm, it is too thick to give the wearer the feeling of hanging the ear hanger, On the other hand, there is no such thing as giving a sense of incongruity by focusing on the part that is too thin to touch the ear.

  According to the invention which concerns on Claim 5, a 1st folding part is located in the longitudinal direction center part and longitudinal direction both ends of a mask main body, and a 2nd folding part is between adjacent 1st folding parts, and is a mask. Since it is located at both lateral ends of the main body, the mask main body can be appropriately three-dimensionalized by widening the folding portion.

  According to the invention which concerns on Claim 6, a 1st folding part is located only in the vertical direction center part of a mask main body, and a 2nd folding part is between the vertical direction one end of a mask main body, and a 1st folding part, and The one located between the other longitudinal end of the mask body and the first fold part and located on both lateral sides of the mask body, and the length of the second fold part is located on the first fold part side. Since it is long, when the fold part is widened to make the mask body three-dimensional, it can be made into a three-dimensional shape with a texture.

  An embodiment of the mask of the present invention will be described with reference to the drawings.

  1 to 4, reference numeral 1 denotes a gauze type mask. The mask 1 is a sleep mask that is lightweight and does not breathe even when worn, and has excellent moisture retention and is suitable for long-time indoor wearing. The mask 1 is not intended to prevent foreign substances such as bacteria floating in the atmosphere from entering the body. For this reason, a collection filter is arranged inside, or a conventional gauze mask is used. There is no need to stack more than 10 gauze.

  The mask 1 is formed of a substantially rectangular sheet-shaped main body forming member 4 made of one gauze or two to five laminated gauze, and the mask main body 2 covering the nose and mouth of the wearer, and the mask main body 2 and left and right ear hooks 3 that are provided at both lateral ends and are hung on the ears of the wearer.

  As shown in FIGS. 1 and 2, the mask main body 2 has a substantially rectangular planar shape before mounting, but as shown in FIGS. 3 and 4, the mask main body 2 has a three-dimensional shape that draws a dome-shaped curved surface. It becomes a shape.

  The mask body 2 has a plurality of folding parts (folding pieces) 5 that are folded so that the cross-section in a side view is substantially S-shaped and extends along the lateral direction of the mask body 2 in a state before being mounted. The plurality of folding parts 5 include a first folding part (long folding piece) 6 which is a plurality of long folding parts having the same length as the lateral length of the mask body 2 and the lateral direction of the mask body 2. It is comprised with the 2nd folding part (short folding piece) 7 which is a some short folding part which has the length below half of length.

  Five first folding parts 6 are formed, for example, and are located at the longitudinal center part and both longitudinal sides of the mask body 2 (see FIG. 7A). In addition, the second folding part 7 is formed on each of both sides of the mask body 2 in the lateral direction, and there are a total of 12 second folding parts 7 between the adjacent first folding parts 6 and in the lateral direction of the mask body 2. It is located at both end sides, both lateral ends in the vicinity of the upper end that is one longitudinal end of the mask body 2, and both lateral ends in the vicinity of the lower end that is the other longitudinal end of the mask body 2 (see FIG. 7B). ). In addition, the length of each 2nd folding part 7 is substantially the same, and is the half or less of the horizontal direction length of the mask main body 2, ie, is about 1/4 of the horizontal direction length of the mask main body 2, for example.

The main body forming member (gauze fabric) 4 forming the mask main body 2 has a substantially square shape in the unfolded state as shown in FIG. 5, and for example, one of the vertical and horizontal threads per 1 cm ² is formed. It is composed of one gauze having 20 or more (for example, 20), and the other has 26 or more (for example, 26). The mass of the mask body of a conventional flat gauze mask is about 9 to 13 g, but it consists of one gauze in which one of the longitudinal and lateral threads is present and 26 are present per 1 cm ^2. The mass of the main body forming member (mask main body 2) 4 is approximately 3 g, which is about one third to one fourth lighter than the conventional one, and the troublesomeness at the time of mounting is reduced. The main body forming member 4 may be composed of 2 to 5 laminated gauze.

  Further, the longitudinal length of the main body forming member 4 is preferably 200 to 300 mm, and the lateral length of the main body forming member 4 is preferably 100 to 180 mm.

  The vertical length of the mask body of the conventional flat gauze mask is about 100 mm, and the vertical length of the mask body of the pleated type nonwoven fabric mask is about 170 mm. In the mask 1 according to the present embodiment, the main body forming member 4 having a longitudinal length of 200 to 300 mm and a mass of about 3 g is used, and if the main body forming member 4 having such a size is used, many folds are formed. Since the tatami portion 5 can be formed, a relaxed three-dimensional shape is obtained. When the mask body 2 is formed with the body forming member 4 having a longitudinal length of about 300 mm, the throat of the wearer can be covered by opening the mask body 2 so that the throat is kept moist. At the same time, the throat is kept warm and the cilia behind the throat can be activated.

  On the other hand, each ear hanger 3 is formed by a string member 9 having a substantially circular cross section and a diameter of 0.25 to 2 mm in cross section. It is inserted into a string insertion part 15 formed in the part. The string member 9 may be made of an elastic material that expands and contracts, or may be made of an inelastic material that does not expand and contract.

  In addition, the thickness of the string member which forms the ear hanger of the conventional mask is 2.5 mm or more in diameter. When the diameter of the string member 9 exceeds 2 mm, the wearer is given a feeling that the ear-hanging body 3 is hung, so that there is a possibility that bothering may be felt depending on the wearing for a long time. On the other hand, if the diameter of the string member 9 is less than 0.25 mm, there is a possibility that a sense of incongruity may be given because the sensation concentrates on the portion that contacts the wearer's ear. The length of the string member 9 is preferably a relaxed length that does not cause the string member 9 to be taut when it is hooked on the ear.

  Next, a method for manufacturing the mask 1 will be described.

  As shown in FIG. 5, a rectangular main body forming member (gauze dough) 4 has a first fold line (long fold line) 11 and a main body extending along the lateral direction of the main body forming member 4 along the lateral direction of the main body forming member 4. A second fold line (short fold line) 12 having a length equal to or less than half the lateral length of the forming member is provided.

  Then, as shown in FIG. 6, the main body forming member 4 is folded along the first fold line 11 and the second fold line 12 so that the cross-section in a side view is substantially S-shaped. A plurality of first foldable portions 6 and second foldable portions 7 extending along the vertical direction are arranged in parallel in the vertical direction, and then both lateral ends of the main body forming member 4 are sewn.

  In the main body forming member 4 folded in this way, the second folding portion 7 exists only at both lateral ends of the main body forming member 4 and does not exist at the central portion in the horizontal direction of the main body forming member 4. The vertical length at the horizontal central portion of the main body forming member 4 in the state is longer than the vertical length of the side ends that are both ends in the horizontal direction, and therefore the upper and lower horizontal sides of the main body forming member 4 in the folded state are gentle. Draw a curve.

  When the main body forming member (mask main body 2) 4 is viewed in a cross-sectional side view, the first folding section 6 and the second folding section 7 appear alternately on both ends in the lateral direction (FIG. 7B). reference). In addition, the length of the folding portion 5 formed on the front (back) surface of the main body forming member 4 is determined by the distance between the pair of folding lines 11 and 12 and the difference in inclination between the folding lines 11 and 12 (see FIG. 5). ). That is, the first fold portion 6 has the same inclination of the first fold line 11 along the width direction of the main body forming member 4 regardless of whether the pair of the first fold lines 11 is wide or narrow in the vertical direction. It can be formed by setting the degree (substantially parallel). On the other hand, the second folding unit 7 is formed so that the vertical interval between the pair of second folding lines 12 gradually decreases toward the center in the width direction of the main body forming member 4. Therefore, even when the distance between the pair of second folding lines 12 is wide, the second folding part 7 can be formed by increasing the inclination of both the second folding lines 12.

  In addition, the folding part 5 does not need to provide the long 1st folding part 6 and the short 2nd folding part 7 alternately (refer FIG. 8), and the folding direction does not need to be always constant (FIG. 9). reference). The number of folding parts 5 and the folding method are appropriately determined in consideration of the dome-shaped three-dimensional shape and texture when the mask body 2 is expanded (FIGS. 3 and 4).

  Thereafter, as shown in FIG. 10, a fray stop 13 is applied to the peripheral end portion of the main body forming member 4. In addition, if the fray stop 13 is originally provided at the upper end and the lower end of the main body forming member 4, the fray stop 13 is provided only at both lateral ends.

  Finally, both end portions in the horizontal direction of the main body forming member 4 are folded back along the folding line 14 to form the string insertion part 15, and the string member 9 is inserted into the string insertion part 15 and sewn.

  The gauze mask main body 2 formed from the main body forming member 4 is composed of one gauze or two to five laminated gauze, and thus is formed of more than ten gauze. Better breathability than conventional gauze masks.

  In addition, since the mask body 2 has a plurality of foldable folding parts 5, the size of the mask body 2 is the same when compared with the mask body of a conventional flat gauze mask. Even so, the amount of gauze per layer to be used is larger than before. And the mask main body 2 may use the gauze about twice as large as one layer, and when six or more sheets of gauze are laminated | stacked, it may become heavier than the conventional flat mask. Therefore, in order to obtain a lightweight mask main body 2, it is necessary to reduce the number of gauze to be stacked to five or less. Moreover, when the mask main body 2 is formed of six or more gauze, the laminated gauze is bulky, so even if the mask main body 2 has a dome-shaped three-dimensional shape, it is closest to the skin side inside the mask main body 2. There is a possibility that the gauze will cling to the mouth, and it will be difficult to create a texture that does not give a feeling of wearing.

  Furthermore, there are several types of gauze depending on the size of the stitches. The mask main body 2 can obtain the mask main body 2 with good moisture retention and wearability by appropriately determining the type of gauze and the number of layers of the gauze (see Table 1). The size of the gauze stitches is slightly determined depending on the diameter of the yarn, but is roughly determined by the number of yarns (the number of yarns) in the longitudinal and lateral directions existing in the range of 1 cm × 1 cm.

  As shown in Table 1, if a gauze with a stitch number of 20 (books) x 26 (books) is used, even if the mask body 2 is formed with a single gauze, the mask body 2 and the mouth of the wearer The humidity of the space between the two reaches 80%, and it can be confirmed that the humidity of the space becomes 80% or more by laminating two or more gauze even if the number of gauze is other than this. It was. Therefore, it is possible to form a mask body 2 that is lightweight and has good moisture retention. Table 1 shows the results of calculating the average humidity of each measurement value by continuously wearing a mask created under each condition for 6 hours, measuring the humidity of the space between the mask body 2 and the mouth every 15 seconds. It is.

  In addition, since the mask body 2 is formed with a plurality of folding parts 5 including the first folding part 6 and the second folding part 7, the mask body when the folding part 5 is unfolded, that is, spread. 2 draws a gentle dome-shaped curved surface. Therefore, an appropriate space is formed between the mask main body 2 and the wearer's mouth, and the mask main body 2 does not cling to the wearer's mouth. I hardly feel it. Moreover, since moisture is appropriately held by natural fibers of gauze and the like, it is excellent in moisture retention and can be prevented from drying of the nose and throat by the held moisture, which is suitable for prevention and treatment of colds. Furthermore, since the mask body 2 is lightweight and has good air permeability, it can be worn with a relaxed feeling for a long time without causing a feeling of wearing, and is suitable for wearing for a long time indoors, for example, at bedtime. It is preferable.

  Note that the mask body 2 having high moisturizing properties activates the movement of the cilia of the nose and the respiratory tract, so that the healing of the cold can be accelerated and the effect of excluding foreign matter from the body can be enhanced.

  In addition, the humidity and temperature of the air inhaled from outside the body are adjusted in the nasal cavity (humidity 80 to 95%, temperature 35 to 37 ° C), but if the air is dry, a large amount of mucus is required for humidification. Therefore, it is not desirable that moisture is released to the outside of the mask body 2 together with the exhalation, but the natural fiber gauze is hygroscopic and water-absorbing. Therefore, when the gauze type mask 1 is worn, it is included in the exhalation. Moisture is absorbed and retained by the natural fiber of gauze. Since the moisture absorbed by the natural fibers increases the humidity of the mask 1 and the space of the nose and mouth, it is possible to reliably prevent the wearer's nose and throat from drying. On the other hand, since the synthetic fibers usually used as the material for the non-woven mask have almost no moisture absorption and water absorption, the amount of moisture contained in the breath is absorbed by the fibers is small. Therefore, a non-woven mask without a hygroscopic sheet or the like cannot be expected to have a moisturizing effect like a gauze mask.

  The mask body 2 is not limited to the configuration shown in FIG. 1 and the like, and as shown in FIG. 11, the two first folding parts 6 are located only in the center in the vertical direction of the mask body 2, and the left and right respectively A total of 18 second folds 7 formed 9 each are between the upper end, which is one longitudinal end of the mask body 2, and the first fold 6, and the lower end, which is the other longitudinal end of the mask body 2, and the first. A configuration in which the length of the second fold 7 is between the fold 6 and the side of the mask body 2 in the lateral direction, and the length of the second fold 7 is closer to the first fold 6 But you can.
