Description

[Technical Field]

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

[0002] A mask is disclosed in which upright sheets are arranged on the upper and lower parts of the mask that face the wearer's skin (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2021-172948 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the above-mentioned conventional example, the area of ​​the standing sheet is small and there is little room for deformation when wearing the mask, so it is thought to be difficult to make the standing sheet conform to the shape of the face when wearing the mask.

[0005] The present invention aims to improve the wearability of a mask. [Means for solving the problem]

[0006] The mask according to the first aspect has a main body sheet that covers the mouth and nose of the wearer, a standing sheet that is positioned closer to the wearer's skin than the main body sheet and is joined to the upper and lower edges of the main body sheet, and a contact sheet that is positioned closer to the skin than the standing sheet and is joined to the central edges of the standing sheet in the vertical direction, forming a surface that comes into contact with the skin.

[0007] In this mask, the standing sheet is positioned closer to the wearer's skin than the main sheet, and can stand up from the upper and lower edges where the standing sheet joins with the main sheet. Furthermore, a contact sheet is provided closer to the wearer's skin than the standing sheet, and can stand up from the center edge in the vertical direction where the standing sheet joins with the main sheet. Therefore, the standing sheet can stand up not only from the main sheet but also from the contact sheet. Because this contact sheet is the surface that comes into contact with the wearer's skin, it adheres better to the wearer's nose and chin, improving comfort. This also reduces air leakage between the mask and the skin. Furthermore, pinching the contact sheet makes it easier to raise the standing sheet when wearing the mask.

[0008] In a second aspect, in the mask according to the first aspect, the edges of the upper and lower standing sheets on the vertical center side are close to or abut against each other before use.

[0009] In this mask, the vertical center edges of the upper and lower stand-up sheets are close to or abutting each other before use, ensuring the vertical width of the stand-up sheets. This ensures the stand-up height of the stand-up sheets and improves the space around the mouth when worn. This prevents the main sheet from sticking to the mouth, making for a comfortable fit.

[0010] In the third aspect, in the mask according to the first or second aspect, the standing sheet is formed by folding the mask base material toward the skin at the upper and lower ends of the part that will become the main sheet, and the contact sheet is formed by folding the mask base material toward the skin at the lower and upper ends of the part that will become the standing sheet.

[0011] In this mask, the main sheet, standing sheet, and contact sheet are formed by folding back the mask base material, so it can be produced using existing equipment.

[0012] A fourth aspect is the mask according to any one of the first to third aspects, wherein the upper contact sheet is provided with a nose clamp.

[0013] In this mask, a nose clamp is provided on the upper contact sheet, which improves the fit of the upper contact sheet to the nose. [Effects of the Invention]

[0014] According to the present invention, the wearability of a mask can be improved. [Brief explanation of the drawings]

[0016] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Components indicated by the same reference numerals in each drawing are the same or similar components. Note that duplicated descriptions and reference numerals may be omitted in the embodiments described below. Furthermore, all drawings used in the following description are schematic, and the dimensional relationships and ratios of elements shown in the drawings do not necessarily correspond to the actual ones. Furthermore, the dimensional relationships and ratios of elements between multiple drawings do not necessarily correspond to the actual ones.

[0017] 1 to 4, the mask 10 according to this embodiment is a sanitary mask constructed using a mask substrate such as a nonwoven fabric, and has a main body sheet 12, a standing sheet 14, and a contact sheet 16.

[0018] The main body sheet 12 is a portion that covers the mouth 18A and nose 18B of the wearer 18, and is formed, for example, in a horizontally long rectangle. The main body sheet 12 is designed to cover at least the nostrils of the nose 18B.

[0019] As shown in Figure 4(A), the standing sheet 14 is placed closer to the skin of the wearer 18 than the main sheet 12, and is joined to the upper and lower edges 20, 22 of the main sheet 12. The skin side of the wearer 18 corresponds to the back side when the main sheet 12 is considered to be the front side. The standing sheet 14 is formed, for example, by folding back the upper and lower ends of the portion that will become the main sheet 12 onto the skin side.

[0020] The contact sheet 16 is disposed closer to the skin than the standing sheet 14, is joined to the vertically central edges 30, 32 of the standing sheet 14, and is the portion that comes into contact with the skin. The upper contact sheet 16 is the contact surface with the nose 18B and its lateral portions of the wearer 18. The lower contact sheet 16 is the contact surface with the chin 18C (lower jaw) of the wearer 18. The contact sheet 16 is formed, for example, by folding back the upper and lower ends of the portion that will become the standing sheet 14 toward the skin. In this embodiment, the contact sheet 16 is formed by further folding back the upper and lower ends of the portion that will become the contact sheet 16 toward the main sheet 12.

[0021] A nose clamp 24 corresponding to the nose 18B may be provided on the upper contact sheet 16. The nose clamp 24 is made of a strip-shaped resin or the like that is flexible and has shape retention. This nose clamp 24 is arranged in the horizontal direction between the folded-back portions of the upper contact sheet 16. To determine the position of the nose clamp 24, welded portions 26 are provided in the horizontal direction on the folded-back portions of the contact sheet 16 above and below the nose clamp 24. Note that similar welded portions 28 are also provided on the lower contact sheet 16 that does not have the nose clamp 24.

[0022] As an example, stretchable headrests 34 are provided between the upper and lower contact sheets 16 and the standing sheet 14. Specifically, the headrests 34 are provided between the upper and lower contact sheets 16 and the standing sheet 14 on the vertical center edges 30, 32 sides of the standing sheet 14.

[0023] The width of the contact sheet 16 in the vertical direction is, for example, 30 to 60% of the width of the standing sheet 14. The width of the contact sheet 16 may be the same on the top and bottom, or may be different on the top and bottom.

[0024] The vertical center edges 30, 32 of the upper and lower standing sheets 14 may be close to or in contact with each other before use. Specifically, the folded portions of the contact sheet 16 relative to the upper and lower standing sheets 14 may be close to or in contact with each other (FIG. 4(A)).

[0025] To form the mask 10, the main body sheet 12, the upright sheet 14, and the contact sheet 16 are partially welded to one another. At both left and right ends 36 of the main body sheet 12, welded portions 40 are provided, welding the main body sheet 12, the upright sheet 14, and the contact sheet 16 to the ends of the headrest portion 32. Also, welded portions 42 are provided, welding the upright sheet 14 and the contact sheet 16 to one another. The shape and arrangement of the welded portions 42 are arbitrary. In the illustrated example, the welded portions 42 have a central portion 42A located at the center in the left-right direction (within approximately one-third of the left-right length) of the upper and lower edges 20, 22 of the main body sheet 12, and end portions 42B extending diagonally from both ends of the central portion 42A to the center in the up-down direction of the left and right ends 36 of the main body sheet 12. The welded portions 42 are provided, for example, in triplicate at the end portions 42B.

[0026] (action) This embodiment is configured as described above, and its operation will be described below. As shown in FIG. 4, in the mask 10 according to this embodiment, the standing sheet 14 is disposed closer to the wearer's 18's skin than the main sheet 12. The standing sheet 14 can stand up from the upper and lower edges 20, 22, which are the connecting points between the standing sheet 14 and the main sheet 12. The contact sheet 16 is disposed closer to the wearer's 18's skin than the standing sheet 14. The contact sheet 16 can stand up from the central edges 30, 32, which are the connecting points between the standing sheet 14 and the standing sheet 14. Therefore, the standing sheet 14 can stand up not only from the main sheet 12 but also from the contact sheet 16. Because the contact sheet 16 is the contact surface that contacts the wearer's 18's skin, it adheres better to the nose 18B and chin 18C of the wearer, improving comfort (FIG. 5). This also reduces air leakage between the mask 10 and the skin. Furthermore, pinching the contact sheet 16 makes it easier to raise the standing sheet 14 when wearing the mask. In other words, the mask 10 is easy to open, as shown in Fig. 3. In this embodiment, the head hanging portion 34 is designed to be hung on the back of the head 18D of the wearer 18, as shown in Fig. 5.

[0027] The vertical center edges 30, 32 of the upper and lower standing sheets 14 are close to or abutting each other before use, ensuring the vertical width of the standing sheets 14. This ensures the standing height of the standing sheets 14, as shown in Figure 6, and improves the space around the mouth 18A when worn. This makes it difficult for the main sheet 12 to stick to the mouth 18A, resulting in a comfortable fit.

[0028] The main sheet 12, standing sheet 14, and contact sheet 16 are made by folding back the mask base material, so they can be produced using existing equipment. In addition, the upper contact sheet 16 is provided with a nose clamp 24, which improves the fit of the upper contact sheet 16 to the nose 18B (Figure 5).

[0029] In this way, according to this embodiment, the wearability of the mask can be improved.

[0030] [Other embodiments] The above describes one example of an embodiment of the present invention, but the embodiment of the present invention is not limited to the above, and it goes without saying that various modifications can be made without departing from the spirit of the present invention.

[0031] Although the overall shape of the mask 10 is rectangular when viewed from the front, the overall shape can be changed as desired, and for example, the mask 10 may have a shape in which the portion outside the end 42B of the welded portion 42 is removed.

[0032] Although the mask 10 has the head loop portion 34, it may have ear loop portions instead of the head loop portion 34. [Explanation of symbols]
