Description

Technical Field

[0001] The utility model relates to a mask structure, and in particular to a mask with viscosity. Background Art

[0002] In addition to being used for medical protection, masks have also seen an increasing demand in recent years due to the increasing severity of air pollution. They are used to prevent allergens such as dust and haze from entering the human body through the respiratory tract and affecting human health.

[0003] Generally, a nose bridge strip is provided on the upper edge of a common mask on the market. When a user wears the mask, the nose bridge strip is pressed against the nose bridge to improve the fit between the mask and the face.

[0004] However, when the mask is actually worn, the nose bridge strip of the mask cannot effectively fit the user's nose bridge, resulting in a gap between the upper edge of the mask corresponding to the nose bridge and the nose wing, causing germs and dust in the air to enter the mouth and nose through the gap; in addition, if the user also wears glasses, the hot air exhaled by the user will rush upward through the gap, causing the lenses of the glasses to fog up, thereby affecting vision.

[0005] Therefore, the design of existing masks is still not perfect and needs to be improved. Utility Model Content

[0006] In view of this, the purpose of the present invention is to provide a mask that increases the fit between the mask and the nose and prevents germs and dust in the air from entering the inside of the mask through the gaps.

[0007] In order to achieve the above-mentioned object, the present invention provides a mask, comprising a mask body and a nose bridge patch. The mask body has a top edge corresponding to the bridge of the user's nose; the nose bridge patch has a first fitting surface, the first fitting surface is located on the inner side of the nose bridge patch and faces an inner side surface of the mask body, wherein the nose bridge patch has a first fixed portion and a first flip portion, wherein the first fixed portion is located at one end of the nose bridge patch and is fixed to the inner side surface of the mask body corresponding to the top edge, and the first flip portion is located at the other end of the nose bridge patch and swings relative to the first fixed portion between a first position and a second position; when the first flip portion is located at the first position, the first flip portion is retracted inside the mask body, and the first fitting surface is attached to the inner side surface of the mask body; when the first flip portion is located at the second position, the first flip portion is folded upward relative to the first fixed portion toward the top edge, and the first fitting surface is flipped open by the first flip portion and exposed on the inner side surface of the mask body.

[0008] The present invention provides the advantage that, by designing the nose bridge patch with the first fitting surface, when the user wears the mask, the first fitting surface fits the user's nose bridge, thereby increasing the fit between the mask and the nose, preventing airborne germs and dust from directly entering the mask through the gaps, thereby reducing the risk of respiratory infections and allergic reactions. Furthermore, if the user also wears glasses, the hot air exhaled by the user can be directed through the gap between the inner side surface, bottom edge, and chin of the mask body, preventing the hot air from escaping directly upwards and fogging the glasses, thereby affecting vision.

[0063] In order to more clearly illustrate the present invention, a preferred embodiment is given below and described in detail with reference to the accompanying drawings. Figures 1 to 3 FIG. 1 shows a mask 100 according to a first preferred embodiment of the present invention, comprising a mask body 10 and a nose bridge patch 20 .

[0064] The mask body 10 is a flat mask, and the mask body 10 has an inner side 11, which corresponds to contacting the user's face. The mask body 10 has a top edge 12, a bottom edge 13, two side edges 14 and two ear hooks 15, wherein the top edge 12 is located corresponding to the user's nose bridge; the bottom edge 13 is located on the bottom side of the mask body 10 relative to the top edge 12; the two side edges 14 are respectively located on both sides of the mask body 10 and connect the two ends of the top edge 12 and the bottom edge 13; the two ear hooks 15 are respectively connected to the two side edges 14, and the two ear hooks 15 are used to hang on the user's ears to fix the mask 100 to the user's face; in this embodiment, the mask body 10 is defined with a fold line L, which passes through the top edge 12 and the bottom edge 13.

[0065] The nose bridge patch 20 is in the shape of a horizontal strip and is located on the inner side 11 of the mask body 10. It has a first section 202 and a second section 204 based on the fold line L. The first section 202 and the second section 204 together form the nose bridge patch 20; the nose bridge patch 20 has a first fitting surface 22 and a first abutting surface 24 facing each other, wherein the first fitting surface 22 is located on the inner side of the nose bridge patch 20 and faces the inner side 11 of the mask body 10. More specifically, the nose bridge patch 20 has a first fixing portion 26 and a first flip portion 28, wherein the first fixing portion 26 is located at one end of the nose bridge patch 20 and is fixed to the inner side surface 11 of the mask body 10 corresponding to the top edge 12. In this embodiment, the first fixing portion 26 of the nose bridge patch 20 is sewn to the inner side surface 11 of the mask body 10 corresponding to the top edge 12, and the first flip portion 28 is located at the other end of the nose bridge patch 20 and can swing relative to the first fixing portion 26 at a first position P1 and a second position P2.

[0066] like Figure 2 As shown, when the first flip portion 28 is located at the first position P1, the first flip portion 28 is retracted into the inner side of the mask body 10, and the first fitting surface 22 is attached to the inner side surface 11 of the mask body 10. Figure 3 As shown, when the first flip portion 28 is located at the second position P2, the first flip portion 28 is folded upward toward the top edge 12 relative to the first fixing portion 26, and the first fitting surface 22 is flipped open by the first flip portion 28 and exposed on the inner side surface 11 of the mask body 10, and the first flip portion 28 protrudes relatively from the top edge 12 of the mask body 10.

[0067] In this way, when the user wants to wear the mask 100, the first flap 28 is moved from the first position P1 to the second position P2, and the first fitting surface 22 is fitted to the bridge of the nose to increase the fit between the mask 100 and the nose, and prevent germs and dust in the air from directly entering the inner side of the mask 100 through the gap between the top edge 12 and the bridge of the nose, thereby reducing the risk of respiratory infections and allergic reactions. In addition, the effect of the bridge of the nose patch 20 being attached to the bridge of the user's nose makes it possible for the mask body 10 to not include a bridge of the nose strip corresponding to the top edge 12, thereby reducing the cost of the mask body 10. In addition, if the user also wears glasses, the hot air exhaled by the user can be discharged through the gap between the bottom edge 13 of the inner side surface 11 of the mask body 10 and the chin, thereby preventing the hot air from directly escaping upwards and causing the glasses to fog up and affect the vision.

[0068] In addition, when the user wants to remove and fold the mask 100, the first flip portion 28 is moved from the second position P2 to the first position P1. When the mask body 10 is folded in half based on the fold line L, the mask body 10 links the nose bridge patch 20 to be folded in half based on the fold line L, and the first section 202 and the second section 204 of the nose bridge patch 20 are abutted against each other with the first abutting surface 24. In this way, the nose bridge patch 20 is folded inside the mask body 10, and the first abutting surface of the nose bridge patch 20 is not exposed to reduce the stickiness, thereby achieving the effect of effectively folding the mask 100.

[0069] Please refer to Figures 4 and 5 As shown, the mask 100A of the second preferred embodiment of the present invention includes the aforementioned mask body 10, the aforementioned nose bridge patch 20 and two cheek patches 30. The structures of the mask body 10 and the nose bridge patch 20 of the second preferred embodiment of the present invention are roughly the same as those described in the first preferred embodiment of the present invention, and will not be repeated here. The differences are described in detail below.

[0070] The two cheek patches 30 are located on the inner side surface 11 of the mask body 10 and are correspondingly provided on the two side edges 14. Each cheek patch 30 is in the shape of a straight strip. The two cheek patches 30 have a second fitting surface 32 and a second abutting surface 34 that are opposite to each other, wherein the second fitting surface 32 is located on the inner side of each cheek patch 30 and faces the inner side surface 11 of the mask body 10. More specifically, each cheek patch 30 has a second fixing portion 36 and a second flap portion 38, wherein each second fixing portion 36 is located at one end of each cheek patch 30 and is correspondingly fixed to each side edge 14. In this embodiment, the second fixing portion 36 of each cheek patch 30 is sewn to the inner side surface 11 of the mask body 10 corresponding to each side edge 14. Each second flip portion 38 is located at the other end of each cheek patch 30 and swings relative to each second fixing portion 36 between a third position P3 and a fourth position P4.

[0071] like Figure 4 As shown, when each second flip portion 38 is located at the third position P3, each second flip portion 38 is retracted into the inner side of the mask body 10, and each second fitting surface 32 is attached to the inner side surface 11 of the mask body 10. Figure 5As shown, when each second flip portion 38 is located at the fourth position P4, each second flip portion 38 is folded outward relative to each second fixing portion 36, and each second fitting surface 32 is flipped open by the second flip portion 38 to be exposed on the inner side surface 11 of the mask body 10, and the second flip portion 38 protrudes laterally relative to the two side edges 14 of the mask body 10.

[0072] Thus, when the user wants to wear the mask 100A, the first flap 28 is moved from the first position P1 to the second position P2, and each second flap 38 is moved from the third position P3 to the fourth position P4, thereby fitting the first fitting surface 22 to the nose bridge and each second fitting surface 32 to the cheek, which not only increases the fit between the mask 100A and the nose, but also increases the fit between the mask 100A and the cheek, thereby preventing germs and dust in the air from directly passing through the top edge 12 and the nose. The gaps between the bridges and the gaps between the two side edges 14 and the cheeks allow air to enter the inner side of the mask 100A, thereby improving the seal between the mask 100 and the face, thereby reducing the risk of respiratory infections and allergic reactions. In addition, if the user also wears glasses, the nose bridge patch 20 and the two cheek patches 30 allow the hot air exhaled by the user to be discharged through the gap between the bottom edge 13 of the inner side surface 11 of the mask body 10 and the chin, thereby preventing the hot air from directly escaping upwards and causing the glasses to fog up and affect the vision.

[0073] In addition, if Figures 4 and 5 As shown, the two cheek patches 30 are attached to the cheeks of the user, so that the mask body 10 corresponding to the two side portions 14 does not include the two ear hooks 15, thereby preventing the user's ears from being compressed by the two ear hooks 15 and causing discomfort such as ear pain, thereby improving the wearing comfort of the mask 100A.

[0074] In addition, when the user wants to take off and fold the mask 100A, the first flip portion 28 is moved from the second position P2 to the first position P1, and each second flip portion 38 is moved from the fourth position P4 to the third position P3. When the mask body 10 is folded in half based on the folding line L, the mask body 10 links the nose bridge patch 20 to be folded in half based on the folding line L, and the first section 202 and the second section 204 of the nose bridge patch 20 are abutted with the first abutting surface 24, and the two second abutting surfaces 34 of the two cheek patches 30 are abutted with each other. In this way, the nose bridge patch 20 and the two cheek patches 30 are folded inside the mask body 10, and the first fitting surface 22 of the nose bridge patch 20 and the second fitting surfaces 32 of each cheek patch 30 are not exposed to reduce the stickiness, thereby achieving the effect of effectively folding the mask 100A.

[0075] Please refer to Figures 6 and 7 FIG. 2 shows a mask 200 according to a third preferred embodiment of the present invention, comprising a mask body 40 and a nose bridge patch 50 .

[0076] The mask body 40 is a three-dimensional mask. The mask body 40 has an inner side 41, which corresponds to the face of the user. The mask body 40 has a top edge 42, a bottom edge 43, two side edges 44 and two ear hooks 45, wherein the top edge 42 is located corresponding to the bridge of the user's nose; the bottom edge 43 is located at the bottom side of the mask body 40 relative to the top edge 42; the two side edges 44 are respectively located on both sides of the mask body 40; the two ear hooks 45 are respectively connected to the two sides of the mask body 40. side, and the two side edges 44 are respectively located on the inner sides of the two ear hooks 45; in this embodiment, the mask body 40 is defined with a fold line L1, and the fold line L1 passes through the top edge 42 and the bottom edge 43. The mask body 40 has a left side portion 402 and a right side portion 404 based on the fold line L1. The left side portion 402 and the right side portion 404 together form the mask body 40, wherein one of the ear hooks 45 is connected to the left side portion 402, and the other ear hook 45 is connected to the right side portion 404.

[0077] The nose bridge patch 50 is in the shape of a horizontal strip and is located on the inner side 41 of the mask body 40. It has a first section 502 and a second section 504, based on the fold line L1. The first section 502 and the second section 504 together form the nose bridge patch 50. The nose bridge patch 50 has a first fitting surface 52 and a first abutting surface 54, which are opposite each other. The first fitting surface 52 is located on the inner side of the nose bridge patch 50 and faces the inner side 41 of the mask body 40. More specifically, the nose bridge patch 50 has a first fixing portion 56 and a first flap portion 58. The first fixing portion 56 is located at one end of the nose bridge patch 50 and is fixed to the inner side 41 of the mask body 40 corresponding to the top edge 42. In this embodiment, the first fixing portion 56 of the nose bridge patch 50 is sewn to the inner side 41 of the mask body 40 corresponding to the top edge 42. The first flip portion 58 is located at the other end of the nose bridge patch 50 and can swing relative to the first fixing portion 56 between a first position S1 and a second position S2.

[0078] like Figure 6 As shown, when the first flip portion 58 is located at the first position S1, the first flip portion 58 is retracted inside the mask body 40, and the first fitting surface 52 is attached to the inner side surface 41 of the mask body 40. Figure 7As shown, when the first flip portion 58 is located at the second position S2, the first flip portion 58 is folded upward toward the top edge 42 relative to the first fixing portion 56, and the first fitting surface 52 is flipped open by the first flip portion 58 and exposed on the inner side surface 41 of the mask body 40, and the first flip portion 58 protrudes relatively from the top edge 42 of the mask body 40.

[0079] In this way, when the user wants to wear the mask 200, the first flip part 58 is moved from the first position S1 to the second position S2, and the first fitting surface 52 is fitted to the bridge of the nose to increase the fit between the mask 200 and the nose, and prevent germs and dust in the air from directly entering the inner side of the mask 200 through the gap between the top edge 42 and the bridge of the nose, thereby reducing the risk of respiratory infections and allergic reactions. In addition, the effect of the nose bridge patch 50 being attached to the user's nose bridge makes the mask body 40 corresponding to the top edge 42 not include a nose bridge strip, which correspondingly reduces the cost of the mask body 40. In addition, if the user also wears glasses, the hot air exhaled by the user can be discharged through the gap between the inner side surface 41 of the mask body 40 and the bottom edge 43 and the chin, thereby preventing the hot air from directly rushing upwards and causing the glasses to fog up and affect the vision.

[0080] In addition, when the user wants to remove and fold the mask 200, the first flip portion 58 is moved from the second position S2 to the first position S1. When the mask body 40 is folded in half based on the folding line L1, the mask body 40 links the nose bridge patch 50 to be folded in half based on the folding line L1, and the first section 502 and the second section 504 of the nose bridge patch 50 are abutted with the first abutting surface 54. In this way, the nose bridge patch 50 is folded inside the mask body 40, and the first abutting surface 52 of the nose bridge patch 50 is not exposed to reduce the stickiness, thereby achieving the effect of effectively folding the mask 200.

[0081] In addition, when the mask is to be discarded after use, the first fitting surface 52 of the nose bridge patch 50 is placed in the second position S2, and the mask body 40 is folded in half based on the fold line L1, so that the first section 502 and the second section 504 are fitted together with the first fitting surface 52. In this way, the spread of germs on the surface of the mask 200 can be prevented, reducing the risk of infection by others through contact.

[0082] Please refer to Figures 8 and 9As shown, the mask 200A of the fourth preferred embodiment of the present invention includes the aforementioned mask body 40, the aforementioned nose bridge patch 50 and two cheek patches 60. The structures of the mask body 40 and the nose bridge patch 50 of the fourth preferred embodiment of the present invention are roughly the same as those described in the third preferred embodiment of the present invention, and will not be repeated here. The differences are described in detail below.

[0083] The two cheek patches 60 are located on the inner side 41 of the mask body 40 and are arranged opposite to each other on the left side 402 and the right side 404. Each cheek patch 60 is in the shape of a straight strip. The two cheek patches 60 have a second fitting surface 62 and a second abutting surface 64 that are opposite to each other, wherein the second fitting surface 62 is located on the inner side of each cheek patch 60 and faces the inner side 41 of the mask body 40. More specifically, each cheek patch 60 has a second fixing portion 66 and a second flap portion 68, wherein each second fixing portion 66 is located at one end of each cheek patch 60 and is fixed to the inner side 41 of the mask body 40 corresponding to each side edge 44. In this embodiment, the second fixing portion 66 of each cheek patch 60 is sewn to the inner side 41 of the mask body 40 corresponding to each side edge 44. Each second flip portion 68 is located at the other end of each cheek patch 60 and swings relative to each second fixing portion 66 between a third position S3 and a fourth position S4.

[0084] like Figure 8 As shown, when each second flip portion 68 is located at the third position S3, each second flip portion 68 is retracted into the inner side of the mask body 40, and each second fitting surface 62 is attached to the inner side surface 41 of the mask body 40. Figure 9 As shown, when each second flip portion 68 is located at the fourth position S4, each second flip portion 68 is folded outward toward each side edge 44 relative to each second fixing portion 66, and the two second fitting surfaces 62 are flipped open by the two second flip portions 68 and exposed on the left side portion 402 and the right side portion 404, respectively.

[0085] Thus, when the user wants to wear the mask 200A, the first flap 58 is moved from the first position S1 to the second position S2, and each second flap 68 is moved from the third position S3 to the fourth position S4, thereby fitting the first fitting surface 52 to the nose bridge and each second fitting surface 62 to the cheek, which not only increases the fit between the mask 200A and the nose, but also increases the fit between the mask 200A and the cheek, thereby preventing germs and dust in the air from directly passing through the top edge 42 and the nose. The gaps between the bridges and the gaps between the two side edges 44 and the cheeks allow air to enter the inner side of the mask 200A, thereby improving the close fit between the mask 200A and the face, thereby reducing the risk of respiratory infections and allergic reactions. In addition, if the user also wears glasses, the nose bridge patch 50 and the two cheek patches 60 allow the hot air exhaled by the user to be discharged through the gap between the bottom edge 43 of the inner side surface 41 of the mask body 40 and the chin, thereby preventing the hot air from directly escaping upwards and causing the glasses to fog up, thereby affecting the vision.

[0086] In addition, the effect of the two cheek patches 60 being attached to the cheeks of the user allows the mask body 40 to omit the two ear hooks 45 (not shown in the figure). This can prevent the user's ears from being compressed by the two ear hooks 45 and causing discomfort such as ear pain, thereby improving the wearing comfort of the mask 200A.

[0087] Furthermore, when the mask 200A is to be discarded after use, the second fitting surface 62 of each cheek patch 60 is placed in the fourth position S4, and the mask body 40 is folded in half based on the fold line L1 so that the two second fitting surfaces 62 fit together. This can also prevent the spread of germs on the surface of the mask 200A and reduce the risk of infection by others through contact.

[0088] In summary, the design of the nose bridge patches 20, 50 and the two cheek patches 30, 60 can not only increase the tightness between the mask 100, 100A, 200, 200A and the nose, but also increase the fit between the mask 100A, 200A and the cheeks, thereby improving the tightness between the mask 100, 100A, 200, 200A and the face, thereby reducing the risk of respiratory infections and allergic reactions; in addition, the nose bridge patches 20, 50 and the two cheek patches 30, 60 can be applied to flat mask types (see Figure 1 ), also suitable for three-dimensional masks (refer to Figure 6 thereby, the nose bridge patch 20, 50 and the two cheek patches 30, 60 can be applied to different types of masks, and can also achieve the purpose of increasing the fit of the mask and the face.

[0089] It is worth mentioning that in the first preferred embodiment to the fourth preferred embodiment, when the first flip portion 28, 58 is located at the second position P2, S2, the first flip portion 28, 58 will protrude relatively from the top edge 12, 42 of the mask body 10, 40. In other embodiments, when the first flip portion 28, 58 is located at the second position P2, S2, the first flip portion 28, 58 may not protrude relative to the top edge 12, 42; the two cheek patches 30, 60 in the mask 100A of the second preferred embodiment and the mask 200A of the fourth preferred embodiment may also be of other forms, for example, the second abutting surface 34, 64 of each cheek patch 30, 60 is fixed in a manner facing the inner side surface 11, 41 of the mask body 10, 40, so that the second fitting surface 32, 62 is exposed on the inner side surface 11, 41 of the mask body 10, 40, and the design of the second fixing portion 36, 66 and the second flip portion 38, 68 is omitted.
