This application claims priority to Taiwanese Invention patent application Ser. No. 11/211,9772, filed on May 26, 2023.
The disclosure relates to a medical device, more particularly to a face mask adaptable for different nasal bridges.
A conventional face mask includes a mask body, an assembly, and a cover body that is connected to the mask body through the assembly.
The mask body is made of a soft material, and is flexible and deformable. However, since heights of nasal bridges of different users of the face mask vary and deformation of the cover body is restricted by the structure thereof when the face mask is being worn, the cover body may not fit some users.
Therefore, an object of the disclosure is to provide a face mask adaptable for different nasal bridges that can alleviate at least one of the drawbacks of the prior art.
According to the disclosure, the face mask includes a main body and a soft cover. The main body is made of a rigid plastic material, is cup-shaped, and includes a peripheral edge, and a protrusion that is spaced apart from the peripheral edge in a transverse direction. The main body is tapered from the peripheral edge toward the protrusion. The soft cover is made of a flexible plastic material, surrounds the main body, and is fixed to the peripheral edge of the main body.
The peripheral edge of the main body has a bottom section, a top section that is opposite to the bottom section, and two side sections that are connected between the bottom section and the top section. The top section is curved, and has two end portions that are respectively connected to the side sections, a central portion that is located between the end portions and the protrusion, and two oblique portions each of which is connected between a respective one of the end portions and the central portion.
The soft cover has a lower section that is fixed to the bottom section of the peripheral edge, a nose section that is opposite to the lower section, and two side sections that are connected between the lower section and the nose section and that respectively correspond to the side sections of the peripheral edge. The nose section has a first deformation region, and a second deformation region that is connected to the first deformation region and that protrudes relative to the side sections of the soft cover. The second deformation region is sealingly connected to the top section of the peripheral edge, and has a wide edge that is connected to the first deformation region, a narrow edge that is connected to the central portion of the peripheral edge, and two inclined edges that are connected between the wide edge and the narrow edge.
Other features and advantages of the disclosure will become apparent in the following detailed description of the embodiment(s) with reference to the accompanying drawings. It is noted that various features may not be drawn to scale.

The main body 10 is made of a rigid plastic material, is cup-shaped, and includes a peripheral edge 11, a protrusion 12 that is spaced apart from the peripheral edge 11 in a transverse direction (X), and a connecting pipe 13 that is fixed to the protrusion 12 and that extends in the transverse direction (X). The main body 10 is tapered from the peripheral edge 11 toward the protrusion 12. The peripheral edge 11 has a bottom section 111, a top section 112 that is opposite to the bottom section 111 in a longitudinal direction (Y) perpendicular to the transverse direction (X), and two side sections 113 that are connected between the bottom section 111 and the top section 112. The top section 112 is curved, and has two end portions 114 that are respectively connected to the side sections 113, a central portion 115 that is located between the end portions 114 and the protrusion 12, and two oblique portions 116 each of which is connected between a respective one of the end portions 114 and the central portion 115. A ratio of a distance (w) between the end portions 114 in a direction perpendicular to the transverse direction (X) to a total length of the peripheral edge 11 ranges from 0.09 to 0.11. Each of the oblique portions 116 cooperates with a respective one of the side sections 113 that is connected to the respective one of the end portions 114 to form an angle (0) that is an obtuse angle.
The soft cover 20 is made of a flexible plastic material, surrounds the main body 10, and is fixed to the peripheral edge 11 of the main body 10 by using overmolding technology. The soft cover 20 has a lower section 21 that is fixed to the bottom section 111 of the peripheral edge 11, a nose section 22 that is opposite to the lower section 21, and two side sections 23 that are connected between the lower section 21 and the nose section 22 and that respectively correspond to the side sections 113 of the peripheral edge 11. The nose section 22 has a first deformation region 221, and a second deformation region 222 that is connected to the first deformation region 221 and that protrudes relative to the side sections 23 of the soft cover 20. The second deformation region 222 is sealingly connected to the top section 112 of the peripheral edge 11, and has a wide edge 223 that is connected to the first deformation region 221, a narrow edge 224 that is connected to the central portion 115 of the peripheral edge 11, and two inclined edges 225 that are connected between the wide edge 223 and the narrow edge 224. A ratio of a distance (h) between the wide edge 223 (in particular, a central point of the wide edge 223) and the narrow edge 224 (in particular, a central point of the narrow edge 224) of the second deformation region 222 of the nose section 22 to the distance (w) between the end portions 114 of the top section 112 of the peripheral edge 11 in a direction perpendicular to the transverse direction (X) ranges from 0.3 to 0.35. A cross section of the first deformation region 221 of the nose section 22 that is perpendicular to a direction perpendicular to the transverse direction (X) and the longitudinal direction (Y) is invertedly J-shaped. A cross section of the lower section 21 that is perpendicular to the direction perpendicular to the transverse direction (X) and the longitudinal direction (Y) is invertedly J-shaped. Cross sections of the peripheral sections 23 that are perpendicular to the longitudinal direction (Y) are invertedly J-shaped.
To further understand generated functions, used technical means, and the expected effect of the disclosure, the disclosure is further described below.

Since the first deformation region 221 and the second deformation region 222 of the nose section 22 of the soft cover 20 are flexible and deformable, when the nose section 22 of the soft cover 20 is compressed by nasal bridges with different heights, the first deformation region 221 or the second deformation region 222 may deform relative to the main body 10. Furthermore, resilience of the nose section 22 allows the nose section 22 to fit more closely to the nasal bridges.
In summary, according to the disclosure, the main body 10 is made of the rigid plastic material, the top section 112 of the peripheral edge 11 of the main body 10 is curved, the soft cover 20 is made of the flexible plastic material, and the nose section 22 of the soft cover 20 is sealingly connected to the top section 112 of the main body 10, so that the nose section 22 has a relatively high deformability. Furthermore, when the face mask is being worn by a user, the first deformation region 221 and the second deformation region 222 of the nose section 22 deform in different levels such that the face mask may be adaptable for nasal bridges with different heights. In addition, the face mask of the disclosure has a simple structure, and is easy to assemble. Therefore, the object of the disclosure is achieved.
