Description

[Technical Field]

[0001] The present disclosure relates to a mask. [Background technology]

[0002] The mask described in Patent Document 1 is made of nonwoven fabric and has a covering part that covers at least the mouth, and a pair of ear loops fixed to the upper and lower ends of both ends of the covering part, and is equipped with a leak prevention part consisting of a strip-shaped body with one side fixed to the covering part so as to extend from both ends of the covering part on the wearer's side toward the center.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-217142 Summary of the Invention [Problem to be solved by the invention]

[0004] Conventionally, there has been a mask that includes a main sheet that covers the wearer's mouth from the front of the wearer, an upper standing sheet that starts from the upper edge of the main sheet and rises toward the wearer's skin, and a lower standing sheet that starts from the lower edge of the main sheet and rises toward the wearer's skin. Specifically, the upper standing sheet starts from the upper edge of the main sheet and rises toward the wearer's skin, covering the area between the skin surface of the upper part of the wearer's mouth and the upper edge of the main sheet. Also, the lower standing sheet starts from the lower edge of the main sheet and rises toward the skin of the wearer, covering the area between the skin surface of the lower part of the wearer's mouth and the lower edge of the main sheet.

[0005] In such a mask, when the upper and lower standing sheets are folded, the lower end of the upper standing sheet overlaps the upper end of the lower standing sheet, and the wearer cannot insert their fingers between the lower end of the upper standing sheet and the upper end of the lower standing sheet, which makes it difficult to stand the upper and lower standing sheets up relative to the main sheet.

[0006] The object of the present disclosure is to easily make the upper standing sheet and the lower standing sheet stand up relative to the main sheet, compared to a configuration in which the lower end portion of the upper standing sheet and the upper end portion of the lower standing sheet overlap. [Means for solving the problem]

[0007] The mask according to the first aspect comprises a rectangular main sheet that covers the mouth of a wearer and extends in the width direction when viewed from the front; an upper upright sheet that is overlapped with the upper part of the main sheet on the side facing the wearer's skin and can stand up toward the skin starting from the upper edge of the main sheet; inclined joints that are provided on one side and the other side of the width center and extend obliquely in the width direction from the upper edge of the main sheet to the side edge of the main sheet when viewed from the front and join the main sheet and the upper upright sheet; and a lower upright sheet that is overlapped with the lower part of the main sheet on the skin side of the main sheet and can stand up toward the skin starting from the lower edge of the main sheet and is separated in the vertical direction from the upper upright sheet so that the wearer's fingers can be inserted between the upper upright sheet and the lower upright sheet.

[0008] According to the above configuration, the upper and lower standing sheets are spaced apart in the vertical direction, and the wearer's fingers can be inserted into this space. Therefore, compared to a configuration in which the lower end of the upper standing sheet and the upper end of the lower standing sheet overlap, the upper and lower standing sheets can be easily stood up relative to the main sheet.

[0009] The mask of the second aspect is characterized in that the mask of the first aspect has upper and lower joints provided on one side and the other side of the width center, which extend vertically from the upper edge to the inclined joint when viewed from the front, and which join the main body sheet and the upper standing sheet.

[0010] According to the above configuration, the upper and lower joints are provided so as to extend vertically from the upper edge of the main sheet to the inclined joints when viewed from the front, which makes it possible to prevent wrinkles from forming in the width direction in the area sandwiched between the inclined joints and the upper edge of the main sheet when the mask is worn by a wearer.

[0011] The mask according to the third aspect is the mask according to the second aspect, characterized in that a nose clamp is provided at the lower end portion of the upper standing sheet, extending in the width direction, so that the lower end portion conforms to the contours of the wearer's nose, and the nose clamp is positioned below the upper and lower joints in the up-down direction when viewed from the front.

[0012] According to the above configuration, the nose clamp is provided at the lower end portion of the upper standing seat, and this nose clamp is disposed below the upper and lower joint in the vertical direction when viewed from the front. Therefore, the nose clamp can be easily bent to fit the wearer's nose, compared to when the nose clamp is disposed so as to overlap the upper and lower joint in the vertical direction.

[0013] The mask of the fourth aspect is characterized in that the mask of the first aspect has another inclined joint provided on one side and the other side of the widthwise center, extending obliquely from the lower edge of the main body sheet to the side edge of the main body sheet when viewed from the front, and joining the main body sheet and the lower standing sheet, and the lower edge side end of the other inclined joint is positioned outward in the widthwise direction compared to the upper edge side end of the inclined joint.

[0014] According to the above configuration, the lower edge of the other inclined joint is positioned outward in the width direction compared to the upper edge of the inclined joint, thereby increasing the space between the wearer's mouth and the main sheet in the width direction compared to when the lower edge of the other inclined joint is positioned at the same position in the width direction as the upper edge of the inclined joint. [Effects of the Invention]

[0015] According to the present disclosure, the upper standing sheet and the lower standing sheet can be easily made to stand up relative to the main sheet, compared to a configuration in which the lower end portion of the upper standing sheet and the upper end portion of the lower standing sheet overlap.

[0017] An example of a mask according to an embodiment of the present disclosure will be described with reference to Figures 1 to 5. In the figures, arrow H indicates the up-down direction of the mask, arrow W indicates the width direction of the mask, and arrow D indicates the wearing direction in which the wearer puts on the mask. Furthermore, arrows H, W, and D are perpendicular to each other.

[0018] (Mask 10 configuration) As shown in Fig. 1, the mask 10 comprises a rectangular main body sheet 12 and a pair of ear loops 14 that are hung over the wearer's ears when viewed from the front in the wearing direction. Furthermore, as shown in Fig. 2(A), the mask 10 comprises an upper standing sheet 16 that is on the wearer's skin side of the main body sheet 12 and overlaps the upper part of the main body sheet 12, and a lower standing sheet 18 that is on the wearer's skin side of the main body sheet 12 and overlaps the lower part of the main body sheet 12 when viewed from the back in the wearing direction.

[0019] 1 and 2 show the mask 10 in a folded state (before being worn by a wearer). The mask 10 has a shape that is line-symmetrical with respect to an imaginary line extending vertically at the center in the width direction.

[0020] Furthermore, the mask 10 is formed by folding a single sheet member 100, excluding the ear loops 14. This sheet member 100 has a multi-layer structure, and each layer is made of a nonwoven fabric of a thermoplastic synthetic resin, such as polypropylene or polyethylene, for example.

[0021] [Main sheet 12, ear hooks 14] 1, the main body sheet 12 has a rectangular shape extending in the width direction, and a folded portion 22 formed by folding a sheet member 100 is formed at a side edge 12b of the main body sheet 12 so as to extend in the vertical direction, as shown in Figures 2(A) and 2(B). An end of the upper standing sheet 16 is inserted between the upper part of the folded portion 22 and the main body sheet 12, and an end of the lower standing sheet 18 is inserted between the lower part of the folded portion 22 and the main body sheet 12.

[0022] Furthermore, one end of the ear hook portion 14 is joined by a welding portion 24a to the upper portion of the folding portion 22. Specifically, one end of the ear hook portion 14, the folding portion 22, the upper standing sheet 16, and the main body sheet 12 are joined by this welding portion 24a.

[0023] Additionally, the other end of the ear hook portion 14 is joined to the lower portion of the folded portion 22 by a welding portion 24b. Specifically, the other end of the ear hook portion 14, the folded portion 22, the lower standing sheet 18, and the main body sheet 12 are joined by this welding portion 24b.

[0024] Furthermore, a joint 26 that joins the folding portion 22, the upper standing sheet 16, and the main body sheet 12, or the folding portion 22, the lower standing sheet 18, and the main body sheet 12, is provided between the welding portion 24a and the welding portion 24b in the vertical direction so as to extend in the vertical direction. Specifically, the joint 26 is formed by arranging a plurality of welding points 26a at intervals so as to extend in the vertical direction.

[0025] In this embodiment, the length of the main body sheet 12 in the vertical direction is 90 mm.

[0026] In this configuration, as shown in Figs. 4 and 5, when the mask 10 is worn by a wearer, the main body sheet 12 covers the wearer's mouth from the front.

[0027] [Lower standing seat 18] As shown in FIG. 2(A), the lower standing sheet 18 is superimposed on the lower part of the main sheet 12 on the side facing the wearer's skin, and has a rectangular shape extending in the width direction.

[0028] Furthermore, as shown in Fig. 2(C), the upper end portion of the lower standing sheet 18 is folded toward the main body sheet 12, and the folded portion 18a is joined to the base sheet 18b, which faces the skin side of the wearer, in the lower standing sheet 18 by a joint 34. Specifically, as shown in Fig. 2(A), a pair of welding points 34a spaced apart in the vertical direction are arranged at an interval so as to extend in the width direction, thereby forming the joint 34.

[0029] In addition, an inclined joint 36 is provided on one side and the other side of the widthwise center, extending obliquely in the widthwise direction from the lower edge 12a of the main body sheet 12 toward the side edge 12b of the main body sheet 12 when viewed from the front or back, and joining the main body sheet 12 and the lower standing sheet 18. The inclined joint 36 is an example of another inclined joint.

[0030] Specifically, when viewed from the front or rear, the end of the inclined joint 36 on the side edge 12b side extends to the intersection of the end of the folded portion 22 and the upper end of the lower standing sheet 18. The inclined joint 36 is formed by arranging a plurality of welding points 36a at intervals so that they extend in an inclined direction.

[0031] In this configuration, the portion of the lower standing sheet 18 between the pair of inclined joints 36 rises toward the wearer's skin, starting from the lower edge 12a of the main body sheet 12, as shown in Fig. 3. Then, as shown in Figs. 4 and 5, the edge of the lower standing sheet 18 comes into contact with the skin surface of the lower end portion of the wearer's mouth. The lower standing sheet 18 covers the area between the skin surface of the portion below the wearer's mouth and the lower edge 12a of the main body sheet 12.

[0032] [Upper standing seat 16] As shown in FIG. 2(A), the upper standing sheet 16 is superimposed on the upper part of the main sheet 12 on the wearer's skin side relative to the main sheet 12, and has a rectangular shape extending in the width direction.

[0033] The upper standing sheet 16 and the lower standing sheet 18 are spaced apart in the vertical direction, allowing the wearer to insert their fingers between the upper standing sheet 16 and the lower standing sheet 18. In this embodiment, the distance is 5 mm or more and 30 mm or less. In other words, if the height of the main body sheet 12 is 100, the distance is 5.6 mm or more and 33 mm or less.

[0034] Furthermore, as shown in FIG. 2(B), a pleated portion 16a is formed in the center portion of the upper standing sheet 16 in the vertical direction, where the upper standing sheet 16 is folded into a pleat shape.

[0035] Furthermore, the lower portion of the upper standing sheet 16 is folded toward the main body sheet 12, and the folded portion 16b is joined to the base sheet 16c of the upper standing sheet 16, which faces the skin side of the wearer, by a joint 44. Specifically, as shown in FIG. 2(A), a pair of welding points 44a spaced apart in the vertical direction are arranged at a distance so as to extend in the width direction, thereby forming the joint 44. Between the bag-shaped folded portion 16b and the base sheet 16c, a nose clamp 50 is arranged extending in the width direction so that the lower end of the upper standing sheet 16 follows the contours of the wearer's nose. The nose clamp 50 is a member that can be folded and plastically deformed to allow the lower end of the upper standing sheet 16 to follow the contours of the wearer's nose.

[0036] In addition, an inclined joint 46 is provided on one side and the other side of the widthwise center, and extends obliquely in the widthwise direction from the upper edge 12c of the main body sheet 12 toward the side edge 12b of the main body sheet 12 when viewed from the front or back, and joins the main body sheet 12 and the upper standing sheet 16.

[0037] Specifically, when viewed from the front or rear, the end of the inclined joint 46 on the side edge 12b side extends to the intersection of the end of the folded portion 22 and the lower end of the upper standing sheet 16. The inclined joint 46 is formed by arranging a plurality of welding points 46a at intervals so that they extend in an inclined direction.

[0038] Furthermore, the end 47 of the inclined joint 46 on the side of the upper edge 12c of the main body sheet 12 is located more inward in the width direction than the end 37 of the inclined joint 36 on the side of the lower edge 12a of the main body sheet 12. In other words, the end 37 of the inclined joint 36 on the side of the lower edge 12a of the main body sheet 12 is located more outward in the width direction than the end 47 of the inclined joint 46 on the side of the upper edge 12c of the main body sheet 12. Here, the inward in the width direction refers to the central side of the main body sheet 12 in the width direction.

[0039] Furthermore, a joint 48 is formed at the upper end of the upper standing sheet 16 and between the pair of inclined joints 46, joining the upper standing sheet 16 and the main body sheet 12. Specifically, the joint 48 is formed by arranging a plurality of welding points 48a at intervals so as to extend in the width direction.

[0040] Furthermore, upper and lower joints 54 are provided on one side and the other side of the widthwise center, and when viewed from the front or back, extend vertically from the upper edge 12c of the main sheet 12 to the inclined joint 46, and join the main sheet 12 and the upper standing sheet 16.

[0041] Specifically, a plurality of welding points 54a are arranged at intervals so as to extend in the vertical direction, thereby forming the upper and lower joints 54. When viewed from the front or rear, the upper and lower joints 54 are located in an area surrounded by the inclined joints 46, the upper edge 12c of the main body sheet 12, and the folded-back portion 22, and are located between the end portion 47 and the folded-back portion 22 in the width direction. Note that the upper and lower joints 54 are preferably located in the center between the end portion 47 and the side edge 12b in the width direction.

[0042] In the vertical direction, the nose clamp 50 is disposed below the upper and lower joints 54 .

[0043] In this configuration, the portion of the upper standing sheet 16 between the pair of inclined joints 46 rises toward the wearer's skin, starting from the upper edge 12c of the main body sheet 12, as shown in Fig. 3. Then, as shown in Figs. 4 and 5, the edge of the upper standing sheet 16 comes into contact with the lower end of the wearer's nose and with the skin surface of the portion above the wearer's mouth. Then, the upper standing sheet 16 covers the area between the skin surface of the portion above the wearer's mouth and the upper edge 12c of the main body sheet 12.

[0044] (Action, Summary) In the above configuration, when the mask 10 is folded, the upper standing sheet 16 and the lower standing sheet 18 are spaced apart in the vertical direction, and the wearer's fingers can be inserted between the upper standing sheet 16 and the lower standing sheet 18. Therefore, compared to a configuration in which the lower end portion of the upper standing sheet and the upper end portion of the lower standing sheet overlap, the upper standing sheet 16 and the lower standing sheet 18 can be easily made to stand up relative to the main body sheet 12.

[0045] Furthermore, in the mask 10, when viewed from the front or back, the upper and lower joints 54 are disposed in an area surrounded by the inclined joints 46, the upper edge 12c of the main body sheet 12, and the folded-back portions 22. Therefore, when the mask 10 is worn by a wearer, the occurrence of wrinkles extending in the width direction in the area surrounded by the inclined joints 46, the upper edge 12c of the main body sheet 12, and the folded-back portions 22 can be suppressed.

[0046] Furthermore, in the mask 10, the nose clamp 50 is disposed below the upper and lower joint 54 in the vertical direction when viewed from the front or back. Therefore, compared to when the upper and lower joints and the nose clamp overlap in the vertical direction, the flexibility of the nose clamp 50 is not inhibited by the rigidity generated by the upper and lower joint 54, and the nose clamp 50 can be easily bent to fit the wearer's nose.

[0047] Furthermore, in the mask 10, the end 37 of the inclined joint 36 on the side of the lower edge 12a of the main body sheet 12 is positioned outward in the width direction compared to the end 47 of the inclined joint 46 on the side of the upper edge 12c of the main body sheet 12. Therefore, the space between the wearer's mouth and the main body sheet 12 can be made wider in the width direction compared to when the end 37 of the inclined joint 36 on the side of the lower edge 12a of the main body sheet 12 is positioned in the same position as the end 47 of the inclined joint 46 on the side of the upper edge 12c of the main body sheet 12.

[0048] Furthermore, in the mask 10, pleats 16a are formed on the upper standing sheet 16. Therefore, compared to a mask without pleats, the mask has improved stretchability toward the wearer's skin, allowing the end of the upper standing sheet 16 to reliably come into contact with the wearer's skin.

[0049] Although the present disclosure has been described in detail with respect to a specific embodiment, it will be apparent to those skilled in the art that the present disclosure is not limited to such an embodiment and that various other embodiments are possible within the scope of the present disclosure. For example, in the above embodiment, the nose clamp 50 is disposed between the bag-shaped folded portion 16b and the base sheet 16c, but the nose clamp may be welded to the skin-facing side of the base sheet 16c.
