FACE MASK

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.

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a face mask with a structure that creates a larger chamber between the inner surface of the mask and the face of the user.

Description of Related Art

There are a variety of face masks and protective devices known in the art whose design and performance characteristics vary in accordance with the field of application and approved standards. Generally known as face masks, facemasks, simple face masks, surgical masks or respirators, these protective masks and devices are produced in different sizes and shapes, made of different types of materials and fabrics provided with different types of wearing or attachments, and formed with one or several filtering layers in order to achieve different levels of protection and purposes of use.

The major functions of a face mask are to prevent harmful substances in the air inhaled by the user while breathing, prevent the user from exhaling harmful substances into the environment, and stop direct contact of harmful substances released through the nose or mouth with other people. In order to make the mask works effectively, fitting properly on the user's face is important, because leakage affects the protection level of the mask. On the other hand, the user usually wears a mask for a period of time, therefore wearing and breathing comfortably are both important.

A conventional face mask usually only has a single horizontal nose bridge wire to be deformed to suit part of the user's face and it stays very close to or comes in direct contact with the user's face, mouth and nose, during speaking and breathing. The water vapour in the breathed-out air and saliva tends to condense or accumulate on the mask's inner surface and moisturize the inner layer material, which easily makes it uncomfortable to wear and potentially reduces the filter layer performance, especially when the wet surface is in direct contact with the user's face, skin, mouth and nose. The narrow space between the face mask and user's face, mouth and nose also reduces the air-flow area especially during inhalation which makes the inner layer material of the mask might draw toward the user's face, mouth and nose, resulting in difficult breathing.

Some face masks allow users to insert additional filters to serve different purposes of use and level of protection. The inserted additional filter in such mask might move around, be folded or not stay stable inside the mask when wearing it for a period of time, which easily makes it uncomfortable to wear and potentially reduces the filtration performance.

The present invention overcomes the problems of conventional masks and provides a more comfortable wearing experience by making the mask stay secured for a period of time with the choice of increased level of protection and serve different purposes of use defined by users

BRIEF SUMMARY OF THE INVENTION

The present invention seeks to provide solutions to the above-mentioned problems by installing a vertical shapeable material at the central portion of the face mask, in addition to a shapeable nose bridge material. Users can gently bend and shape the vertical shapeable material outward to make a C shape configuration, which renders the mask in a more three-dimensional form in fitting different users' face and create a larger chamber between the face mask and the user's face, mouth and nose at user's control, furthermore, preventing the water vapour in the breathed-out air/saliva from condensing or accumulating easily on the mask's inner layer surface and moisturizing it, making breathing easier and more comfortable than using conventional face mask while properly covering the face to reduce leakage. The specially designed moldable C shape mask helps make the mask fits most face profiles by simple bending step(s). Since each user's face shape varies, different sizes are provided.

On the other hand, an additional layer such as a filter can be inserted between the outer layer and inner layer of the face mask, when the vertical shapeable material installed in the inner layer is bended outward in C shape away from the user's face, user can ensure the filter between the mask is secured in place and fixed in the position because of the added structure and the three dimensional formed generated.

For the purpose of versatility, there are two versions—a disposable version and a reusable version. The mask structure allows the vertical shapeable material and horizontal nose bridge material in the face mask to be either non-removable or removable. Users can take the shapeable material out such as wire or plastic thin plate when washing the mask or replacing it with a new one when it is damaged.

Due to different users' face shape and purposes of use in different environment may vary, the material(s), sizes, number of layers used, making method(s) might also vary. Therefore one or more vertical shapeable materials might need to be put in one of, or more or any layers of the mask, preferable in the inner layer of the mask, at the central portion of the mask to create and maintain the chamber structure. Loops are secured to the two shorter side edges of the mask, which could be strips of conformable material such as elastic straps, fabric, etc for engaging a user's ears, and thus serve as earloops or tie around the user's head.

The loops attached to the main body via the two loop hole spaces created at the two shorter edges are interchangeable, allowing for replacement by the user optionally. The loops, depending on the design, could be ear loops by running around the back of the user's ears, or head loops by running around the back of the user's head either by ties or loop over. The material of the loops is adjustable to elastic bands, straps, fabric etc.

DETAILED DESCRIPTION OF THE INVENTION

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 plate14installed at the central portion inside the mask. The vertical shapeable material14optionally put in one of or more or any of the layer in the mask to create the chamber, preferably inside the inner layer16, which the layer is closer to the user.

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 layer16of 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 material14is shown in the drawing, two or more pieces can be provided optionally.

Referring toFIG. 1which is a plan view showing the outer layer15surface 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 plate11on the top edge between the outer layer15and inner layer16of the mask and two loop hole spaces12and13created on two shorter edges of the mask which can be donned loop materials such as elastic straps, fabric, etc20and21.

Referring toFIG. 2which is a plan view showing the inner layer16surface of the face mask. It shows that the inner layer16is formed by one left and one right panel material such as paper, fabric and non-woven fabric etc. with a vertical shapeable material14installed at the central portion of the inner layer16of the mask and a loop hole spaces12and13created on two shorter end sides of the mask which can be donned loop materials such as elastic straps, fabric, etc.20and21.

Referring toFIG. 3which 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 material15and16, a shapeable nose bridge material11, a vertical shapeable material14and two loop hole spaces20and21. The mask main body can be bent into a C-shape to cover the nose and mouth of the user. The vertical shapeable material14installed at the central portion of the mask main body is in a C-shape to create a larger chamber between the inner layer16surface of the mask and the face of the user.

Referring toFIG. 4which 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 plate11, is installed near the top edge of the mask between the outer layer15and inner layer16, while a vertical shapeable material such as wire or plastic thin plate14is installed in the inner layer16, and is fixed at the central portion. When the face mask is worn, the vertical shapeable material14can be bent into a C-shape to create a larger chamber between the inner layer surface16of the mask and the face of the user, avoiding water vapour and saliva from condensing or accumulating easily on the inner layer surface.

There is a space between the outer layer15and inner layer16, where filter can be inserted optionally to increase the mask protection and serve different purposes of use. A hole18in the inner layer16allows the user to remove the vertical shapeable material14any 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 material14is not removable. A hole19between the outer layer15and inner layer16allows users to remove the horizontal shapeable nose bridge material19any time. Depending on the design of or the purpose of use of the mask, the hole might be close so the horizontal nose bridge material19is not removable.

FIG. 5is an elevation view of a user wearing the mask with respect toFIG. 4, which depicts the large chamber created between the inner layer16surface of the mask and the face of the user, with the vertical shapeable material14being bent into a C-shape and the horizontal shapeable nose bridge material11is 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.

Referring toFIG. 6, which is a schematic cross-sectional view of face mask andFIG. 7is an elevation view of a user wearing the mask with respect toFIG. 6on how to secure the additional inserted layer, which depicts a horizontal nose bridge material11fixated between the outer layer15and inner layer16near the upper edge of the mask main body and a vertical shapeable material14fixated in the inner layer and at the central portion of the mask main body. Space17between the outer layer15and inner layer16allows the optional insertion of additional layer30such as fabric, insulation or filter etc. which the additional insert layer30is not part of the mask structure.
