FACE MASK

Abstract

A face mask has a mask main body, horizontal nose bridge material, vertical shapeable material and two loops. The mask body includes an outer layer formed by panels of breathable material such as fabric, a shapeable nose bridge material and an inner layer formed by panels of breathable material such as fabric, installed with a vertical shapeable material at the central portion. The mask structure has a three dimensional curving profile which creates a larger breathing chamber between the user's face and the mask. The mask's unique profile provides an improved wearing and breathing experience, making it more comfortable than the conventional face masks. Additional layers such as filters can be inserted optionally between the outer layer and inner layer to increase the protection and serve different purposes of use required by the user. The vertical shapeable material can also help secure the position of the inserted layers.

DETAILED DESCRIPTION OF THE INVENTION

[0025] The face mask of the invention is described in detail and with particular reference to the drawings. The mask is intended to create and maintain a more three-dim ensional and larger chamber between the mask and user's face by using the vertical shapeable material such as wire or plastic thin plate 14 installed at the central portion inside the mask. The vertical shapeable material 14 optionally put in one of or more or any of the layer in the mask to create the chamber, preferably inside the inner layer 16, which the layer is closer to the user.

[0026] As the user's face shape and purposes of use in different environment vary, the material(s), sizes, number of material layers use, making method(s) might also vary, therefore one or more than one vertical shapeable material may need to be put in one of or more or any layers in the mask, preferably in the inner layer 16 of the mask at the central portion, which an area around or near the vertical central line of the mask, but not limited to the vertical central line of the mask, of the mask to create and maintain the chamber structure. Although only one vertical shapeable material 14 is shown in the drawing, two or more pieces can be provided optionally.

[0027] Referring to FIG. 1 which is a plan view showing the outer layer 15 surface of the face mask. It shows the outer layer is formed by one left and one right panel material such as paper, fabric and non-woven fabric etc. attached together by different methods such as stitching, welding, thermal bonding, adhesive bonding and laminating etc. with a nose bridge material such as wire or thin plate 11 on the top edge between the outer layer 15 and inner layer 16 of the mask and two loop hole spaces 12 and 13 created on two shorter edges of the mask which can be donned loop materials such as elastic straps, fabric, etc 20 and 21.

[0028] Referring to FIG. 2 which is a plan view showing the inner layer 16 surface of the face mask. It shows that the inner layer 16 is formed by one left and one right panel material such as paper, fabric and non-woven fabric etc. with a vertical shapeable material 14 installed at the central portion of the inner layer 16 of the mask and a loop hole spaces 12 and 13 created on two shorter end sides of the mask which can be donned loop materials such as elastic straps, fabric, etc. 20 and 21.

[0029] Referring to FIG. 3 which is an elevation view showing the left side of the outer layer surface of a folded face mask. The face mask can be folded along the central line of the mask. The face mask structure provided by this invention includes a mask main body comprising of two-layered material 15 and 16, a shapeable nose bridge material 11, a vertical shapeable material 14 and two loop hole spaces 20 and 21. The mask main body can be bent into a C-shape to cover the nose and mouth of the user. The vertical shapeable material 14 installed at the central portion of the mask main body is in a C-shape to create a larger chamber between the inner layer 16 surface of the mask and the face of the user.

[0030] Referring to FIG. 4 which is a perspective view showing the structure of the face mask showing the face mask has a total of four panels which each layer is formed by two panels. Flexible nose bridge adjustment material, such as wire or plastic thin plate 11, is installed near the top edge of the mask between the outer layer 15 and inner layer 16, while a vertical shapeable material such as wire or plastic thin plate 14 is installed in the inner layer 16, and is fixed at the central portion. When the face mask is worn, the vertical shapeable material 14 can be bent into a C-shape to create a larger chamber between the inner layer surface 16 of the mask and the face of the user, avoiding water vapour and saliva from condensing or accumulating easily on the inner layer surface.

[0031] There is a space between the outer layer 15 and inner layer 16, where filter can be inserted optionally to increase the mask protection and serve different purposes of use. A hole 18 in the inner layer 16 allows the user to remove the vertical shapeable material 14 any time, depending on the design of or the purpose of use of the mask such as disposable or reusable usage, the hole might be close so the vertical shapeable material 14 is not removable. A hole 19 between the outer layer 15 and inner layer 16 allows users to remove the horizontal shapeable nose bridge material 19 any time. Depending on the design of or the purpose of use of the mask, the hole might be close so the horizontal nose bridge material 19 is not removable.

[0032] FIG. 5 is an elevation view of a user wearing the mask with respect to FIG. 4, which depicts the large chamber created between the inner layer 16 surface of the mask and the face of the user, with the vertical shapeable material 14 being bent into a C-shape and the horizontal shapeable nose bridge material 11 is shaped to ensure that the upper edge of the mask main body nicely conforms to the contours of the user's face, such that no gap can form and the face mask remains airtight. Wherein when in worn state, the mask is expanded in a three dimensional form created and maintained by the C-shape profile, vertical shapeable material and horizontal shapeable nose bridge material provide a larger breathing chamber between the face mask and the user's face, mouth and nose.

[0033] Referring to FIG. 6, which is a schematic cross-sectional view of face mask and FIG. 7 is an elevation view of a user wearing the mask with respect to FIG. 6 on how to secure the additional inserted layer, which depicts a horizontal nose bridge material 11 fixated between the outer layer 15 and inner layer 16 near the upper edge of the mask main body and a vertical shapeable material 14 fixated in the inner layer and at the central portion of the mask main body. Space 17 between the outer layer 15 and inner layer 16 allows the optional insertion of additional layer 30 such as fabric, insulation or filter etc. which the additional insert layer 30 is not part of the mask structure.
