Description

  The present invention relates to a three-dimensional mask that includes a mask body formed so as to protrude to the front side and covers a nostril and a mouth of a wearer.

  Conventionally, masks are roughly classified according to their shapes into a flat mask and a three-dimensional mask.

  And, unlike the flat mask, the three-dimensional mask is formed with a space between the inner surface of the wearer's lips or nostrils when worn, so the wearer's lips or nostrils are formed on the inner surface of the mask. The lipstick does not touch and does not feel breathless, and it can be generally said that the wearing feeling is better than that of the flat mask.

  As a method for forming such a three-dimensional mask, a nonwoven fabric mainly composed of a suitable synthetic resin fiber having air permeability between a front side member and a back side member formed of a breathable material such as gauze. There is known a method of disposing a core material that is a convex member that is pressure-molded into a predetermined substantially spherical shape. A three-dimensional mask molded by such a molding method has a certain degree of rigidity ( In order to maintain a substantially spherical shape with (strength), a three-dimensional shape is exhibited before the wearer wears (for example, see Patent Document 1).

Further, a predetermined dimension is cut in the vertical direction from the center of the upper edge of the mask body made of a breathable material such as gauze, and both sides of the cut are folded inward to form substantially V-shaped cutouts. There is also known a method for forming a three-dimensional mask that projects toward the outer surface by forming an arc-shaped nose wrapping portion by affixing a fold line and sewing with a predetermined bias cloth interposed therebetween (for example, Patent Document 2). reference.).
JP 2001-37894 A (page 2-3, FIG. 1) Japanese Utility Model Laid-Open No. 1-117365 (page 4-7, FIG. 8)

  However, in the three-dimensional mask described in Patent Document 1 above, the convex member is disposed up to the vicinity of the lower end portion of the mask body, and the lower end portion of the mask main body gently moves toward the face of the wearer according to the shape of the convex member. Although it is possible to secure a space between the lip of the wearer and the inner surface with respect to the nostril when worn, there is a margin in the space for accommodating the portion corresponding to the chin of the wearer. If the lower end of the mask body abuts the wearer's chin portion, or the portion related to the chin portion becomes shallow, the wearer may feel uncomfortable and a good wearing feeling may not be obtained.

  In addition, the three-dimensional mask described in the above-mentioned Patent Document 2 is a three-dimensional mask that protrudes outward near the mouth of the wearer when used upside down. Then, since a part of the surface side member is cut out and the folding curve of the cutout portion is abutted and sewn, the tip of the mask body, that is, the top protrudes linearly, and the space inside the mask body is the above-mentioned Patent Document 1. Compared to the three-dimensional mask described in 1), it tends to be small, and some wearers may feel cramped. Further, the lower part of the mask body is also straight when viewed from the side, and there is no room for a space for accommodating a portion corresponding to the wearer's chin. Furthermore, even if a bendable member is temporarily arranged at the lower end of the mask body and can be deformed along the periphery of the jaw part, it is not easy to stably maintain the shape, and the shape is stable. If the deformation strength of the bendable member is increased in order to maintain it, the wearer feels uncomfortable, which is not preferable.

  Furthermore, in the three-dimensional mask described in each of the above patent documents, a gap is generated between the side part of the wearer's jaw part and the lower end part of the mask body, and allergen substances such as pollen or dust are generated from this gap. There is a problem in that there is a risk of entering between the mask body and the wearer's face.

  For this reason, the wearer is dissatisfied with the feeling of wearing the conventional three-dimensional mask, and in particular, there are many wearers who feel that the feeling of fitting into the jaw portion of the mask body is insufficient.

  The present invention has been made in view of these points, and an object of the present invention is to provide a three-dimensional mask that can obtain a good wearing feeling and is less likely to form a gap with the wearer's chin.

  The three-dimensional mask according to claim 1 is a front side member formed of a breathable material, a back side member formed of the breathable material, and a top portion sandwiched between the front side member and the back side member. A mask body formed so as to protrude to the front surface side, and ear hook portions provided on both sides of the mask body to be engaged with a wearer's ear, And a non-existing region where the convex member is not disposed below the lower end portion of the convex member, and the lower end portion of the mask body expands and contracts between the front surface side member and the rear surface side member. A flexible elastic member is disposed, and the jaw accommodating portion is formed by contraction of the elastic member.

  The three-dimensional mask according to claim 2 is the three-dimensional mask according to claim 1, wherein the convex member has a dimension from the top to the lower end of 45% or more of the dimension from the top to the lower end of the mask body. % Or less.

  The three-dimensional mask according to claim 3 is the three-dimensional mask according to claim 1 or 2, wherein the elastic member has a total length of 30% to 70% of the total length of the lower end portion of the mask body. .

  According to the first aspect of the present invention, the non-existing region where the convex member is not disposed is formed below the convex member of the mask body, and the elastic member having elasticity is disposed at the lower end portion of the mask body. Thus, by forming the chin accommodating portion by contraction of the elastic member, the chin accommodating portion reliably accommodates the wearer's chin portion and obtains a good wearing feeling, and between the chin portion of the wearer A gap can be hardly formed.

  According to the second aspect of the present invention, the mask body and the wearer are measured by setting the dimension from the top to the lower end of the convex member to be 45% or more and 75% or less of the dimension from the top to the lower end of the mask body. The jaw portion of the wearer can be more reliably accommodated in the chin accommodating portion while ensuring a space between the nostril and the vicinity of the lips.

  According to the third aspect of the invention, by setting the total length of the elastic member to 30% or more and 70% or less of the total length of the lower end portion of the mask main body, the jaw portion of the wearer can be reliably stored in the chin storage portion. At the same time, the contraction of the lower end portion of the mask body can be kept moderate, and the burden on the wearer's jaw can be suppressed.

  Hereinafter, the configuration of a three-dimensional mask according to an embodiment of the present invention will be described with reference to the drawings.

  1 to 4, reference numeral 1 denotes a three-dimensional mask. The three-dimensional mask 1 is bonded to a horizontally long rectangular mask body 2 having both sides in the horizontal direction and both ends in the vertical direction, and both sides of the mask body 2. The ear hook 3 is provided.

  And the mask main body 2 has the surface side member 5 and the back surface side member 6 which were formed in the horizontal oblong shape, and the convex-shaped member 7 is clamped between these surface side members 5 and the back surface side member 6. Thus, the central part of the mask body 2 is formed into a three-dimensional shape protruding to the front side, and has become a three-dimensional shape before wearing.

  Further, the mask body 2 is formed with side joint portions 11 and 11 in which the front surface side member 5 and the back surface side member 6 are integrally folded and joined to the wearer P side on both sides. In addition, an upper joint portion 12 and a lower joint portion 13 are formed in which the front surface side member 5 and the back surface side member 6 are integrally folded and joined to the wearer P side at the upper end portion and the lower end portion. In the joint portion 13, the elastic member 14 is disposed in a state of being stretched along the left-right width direction. As a result, the front surface side member 5 and the back surface side member 6 are attracted toward the central portion in the left-right width direction by the contraction force of the elastic member 14 at the lower end portion of the mask body 2, thereby contracting the wearer P. A chin accommodating portion 15 for accommodating the chin portion C is formed.

  Therefore, the mask main body 2 is formed in a substantially pentagonal shape in front view in which the chin accommodating portion 15 which is the central portion of the lower end portion is one of the apexes.

  The front surface side member 5 and the back surface side member 6 are formed of gauze, which is a breathable material such as cotton, nonwoven fabric, or nylon.

  The convex member 7 is formed by press molding after heating and softening within a frame of a convex cup-shaped mold by stacking a plurality of breathable nonwoven fabrics mainly made of synthetic resin fibers made of polypropylene or the like. This is a wearable member that has the rigidity (strength) and the flexibility and is formed in a predetermined substantially spherical shape having the top portion 16 at the substantially central portion. For this reason, when the three-dimensional mask 1 is worn, a space portion is formed between the nostril N and lips L of the wearer P and the back surface side member 6 on the wearer P side of the mask body 2.

  Further, the convex member 7 is formed such that the vertical dimension is smaller than the vertical dimension of the mask body 2, that is, the front surface side member 5 and the back surface member 6, and the mask body 2 is laterally centered. It is supported near the top in the vertical direction. At this time, the convex member 7 preferably has a length in the vertical direction at the central portion in the width direction that is larger than the length in the vertical direction at both ends.

  As a result, the lower end portion of the convex member 7 does not reach the lower end portion of the mask main body 2, and the mask main body 2 below the lower end portion of the convex member 7 has no region 17 where the convex member 7 is not present. The mask body 2 has a convex shape with limited flexibility due to the rigidity of the convex member 7 at the upper center where the convex member 7 exists, but is not present. The lower part where the region 17 is formed is a part having high flexibility without being affected by the rigidity of the convex member 7. Therefore, the chin accommodating part 15 is formed in the lower end part of this mask body 2 with high flexibility.

  Here, the dimensional relationship between the convex member 7 and the mask body 2 is such that the vertical dimension W1 from the top 16 to the lower end of the convex member 7 is the vertical dimension W2 from the top 16 to the lower end of the mask body 2. On the other hand, it is set to 45% to 75%, desirably 50% to 70%, and more desirably about 60%.

  The convex member 7 may not have air permeability, for example, when the size is considerably smaller than that of the mask body 2.

  Each joint part 11, 11, 12, 13 is joined by sewing, welding, or adhesion, for example.

  The elastic member 14 is, for example, string-like rubber, and its total length W3 is 30% to 70%, preferably 40% to 60%, more preferably, with respect to the width dimension W4 of the lower end portion of the mask body 2. Set to about 50%.

  Each ear hook 3 is engaged with a pair of left and right ears E (only one is shown) of the wearer P, and if it is an elastic body having elasticity, for example, a string-like object such as a rubber string, or Arbitrary things, such as strips, such as a nonwoven fabric, can be selected.

  Next, the function and effect of the embodiment will be described.

  When forming the three-dimensional mask 1, the vertical dimension of the convex member 7 is made smaller than the vertical dimension of the mask body 2, and the absence region 17 of the convex member 7 is formed below the mask body 2. The elastic member 14 is disposed between the front surface side member 5 and the back surface side member 6 at the lower end of the mask body 2.

  Therefore, in the absence region 17 between the lower end portion of the convex member 7 and the lower end portion of the mask main body 2, each curve in the vertical direction and the horizontal direction of the chin portion C of the wearer P due to the contraction of the elastic member 14. The chin accommodating part 15 is stably formed in the lower part of the mask body 2 so that the chin accommodating part 15 does not become a burden around the chin part C of the wearer P. The chin portion C of the wearer P is gently wrapped in close contact, and the lower end portion of the mask body 2 is not shallowly related to the chin portion C of the wearer P as in a conventional three-dimensional mask.

  As a result, the three-dimensional mask 1 of the above-described embodiment can suppress the wearer P from feeling uncomfortable at the time of wearing, and a good wearing feeling can be obtained. Also, compared to the conventional three-dimensional mask, Since the mask body 2 is in close contact with the periphery of the chin portion C of the person P and a gap is not easily formed between the chin portion C, particularly the side portions of the chin portion C, the outside air from the direction of arrow D shown in FIG. Inflow of pollen or allergen substances such as dust can be prevented.

  Further, the vertical dimension W1 from the top 16 to the lower end of the convex member 7 is set to 45% or more and 75% or less with respect to the vertical dimension W2 from the top 16 to the lower end of the mask body 2. The chin portion C of the wearer P can be more reliably accommodated in the chin accommodating portion 15 of the mask body 2 while ensuring a space between the mask body 2 and the vicinity of the nostril N and lips L of the wearer P.

  That is, when the vertical dimension W1 from the top 16 to the lower end of the convex member 7 is less than 45% with respect to the vertical dimension W2 from the top 16 to the lower end of the mask body 2, the rigidity of the convex member 7 is increased. The lower portion such as the non-existing region 17 of the mask main body 2 that is not affected by the surface does not follow the shape of the chin portion C of the wearer P due to the contraction force of the elastic member 14, and the front side member 5 and the back side member 6 It is attracted linearly downward in the face direction of the wearer P, and a sufficient space with the mask body 2 in the vicinity of the nostril N and lips L of the wearer P cannot be secured, and the characteristics of the three-dimensional mask 1 are impaired. If the vertical dimension W1 from the top 16 to the lower end of the convex member 7 exceeds 75% with respect to the vertical dimension W2 from the top 16 to the lower end of the mask body 2, the convex member 7 Under the influence of rigidity, the nonexistent region 17 of the convex member 7 causes the jaw portion C of the wearer P to A curved shape that can be accommodated cannot be formed. Therefore, the vertical dimension W1 from the top 16 to the lower end of the convex member 7 is 45% or more and 75% or less, more preferably 50%, relative to the vertical dimension W2 from the top 16 to the lower end of the mask body 2. By setting the ratio to 70% or less, the lower part of the mask body 2 can be formed into a shape having a curved surface that can accommodate the jaw portion C of the wearer P without losing the characteristics of the three-dimensional mask 1. Furthermore, by setting the vertical dimension W1 from the top 16 to the lower end of the convex member 7 to about 60% of the vertical dimension W2 from the top 16 to the lower end of the mask body 2, the wearer A chin receiving portion 15 that can most stably accommodate the jaw portion C of P can be formed.

  Furthermore, by setting the total length W3 of the elastic member 14 to 30% or more and 70% or less with respect to the width dimension W4 of the lower end portion of the mask body 2, the wearer P in the chin receiving portion 15 of the mask body 2 The jaw portion C can be reliably accommodated, the contraction of the lower end portion of the mask body 2 can be kept moderate, and the burden on the jaw portion C of the wearer P can be suppressed.

  That is, if the total length W3 of the elastic member 14 is less than 40% of the width dimension W4 of the lower end portion of the mask main body 2, the contraction of the front surface side member 5 and the back surface side member 6 at the lower end portion of the mask main body 2 is not possible. As a result, it is not easy to form the jaw receiving portion 15 in the lower portion of the mask body 2, and the total length W3 of the elastic member 14 exceeds 70% of the width dimension W4 of the lower end portion of the mask body 2. Then, the contraction of the lower end portion of the mask body 2 becomes too strong, and the burden on the chin portion C of the wearer P becomes high. For this reason, the total length W3 of the elastic member 14 is 30% or more and 70% or less, more preferably 40% or more and 60% or less with respect to the width dimension W4 of the lower end portion of the mask body 2, so The chin receiving portion 15 for securely receiving the chin portion C can be formed without imposing a burden on the portion C, and further, the total length W3 of the elastic member 14 is set to the width dimension W4 of the lower end portion of the mask body 2. On the other hand, by setting to about 50%, the chin accommodating portion 15 that can most stably accommodate the chin portion C of the wearer P can be formed.

  Further, by forming the mask body 2 in a substantially pentagonal shape in front view in which the central portion of the lower end portion is one of the apexes, an ideal jaw housing portion 15 can be easily formed.

  Then, by making the vertical dimension at the central part in the width direction of the convex member 7 larger than the vertical dimension at both end parts, the surface side attracted toward the central part at the lower end of the mask body 2 by the contraction force of the elastic member 14. A delicate balance is achieved between the member 5 and the back surface side member 6, and a chin accommodating portion 15 having a shape along the curve of the chin portion C of the wearer P can be reliably formed in the lower portion of the mask body 2.

  In the above-described embodiment, the vertical dimension at both ends in the width direction of the mask body 2 and the length in the vertical direction at the center part in the width direction are apparently the same, and the mask body 2 has a square shape when viewed from the front. However, as long as the chin accommodating portion 15 can be formed below the mask body 2, the same effects as those of the above-described embodiment can be obtained. That is, the shape of the mask main body 2 in front view is not particularly limited.

  In addition to the above configuration, various other configurations can be selected within a range that can meet the above-described purpose.

  For the three-dimensional mask of the above-described embodiment, the jaw housing part was evaluated according to the specifications shown in FIG. 5 and Table 1. For this evaluation, the size (L size or M size) of the three-dimensional mask 1 was arbitrarily selected according to the size of the face of the wearer P serving as a monitor, and a wearing test was performed by 20 people for each size. The results are shown in Tables 2 and 3. 5, W5 is the width dimension of the upper end of the mask body 2, W6 is the vertical dimension of the mask body 2, W7 is the portion corresponding to the ear hooking section 3, and W8 is the width dimension of the convex member 7. In Tables 2 and 3, the best evaluation is indicated by ◎, the good evaluation by ○, and the bad evaluation by ×.

  As a result, the vertical dimension W1 from the top part 16 to the lower end part of the convex member 7 is 45% or more and 75% or less, preferably 50% or more with respect to the vertical dimension W2 from the top part 16 to the lower end part of the mask body 2. By setting it to 70% or less, it is possible to form a favorable chin receiving portion 15, and more desirably, the vertical dimension W1 from the top 16 to the lower end of the convex member 7 is from the top 16 to the lower end of the mask body 2. By setting it to 60% with respect to the vertical dimension W2, the chin accommodating portion 15 having the highest accommodation capacity can be formed.

  Similarly, by setting the total length W3 of the elastic member 14 to 30% or more and 70% or less, preferably 40% or more and 60% or less with respect to the width dimension W4 of the lower end portion of the mask body 2, a satisfactory jaw housing 15 More desirably, by setting the total length W3 of the elastic member 14 to 50% with respect to the width dimension W4 of the lower end portion of the mask body 2, the jaw housing portion 15 having the highest accommodation property can be formed.
