SINGLE USE FACE SEAL MASK

FIELD

The disclosure relates generally to a single use mask for covid-19 protections and in particular to a complete face seal single use mask.

BACKGROUND

Facial masks are common in various medical settings to reduce the spread of disease, in the building construction trades to reduce breathing intake of dust or fumes, and in travel and other scenarios to reduce contagious disease spread. Currently, due to the covid-19 pandemic, people are wearing various types of masks designed to prevent droplets containing the virus from gaining access to the nasal passages or mouth of a user. Many people are wearing or required to wear facial masks while at work, shopping, and walking outside and many other non-medical situations. Some people were required or voluntarily wore facial masks for extended times—sometimes for multiple hours and sometimes for 8+ hours per day.

Facial masks have typically been constructed using elastic straps which loop around the ears or the back of the head to hold the mask itself against the face. This design can result in wearers suffering back-of-the-ear irritations, where the elastic straps irritate the skin behind the ears. The straps often can become uncomfortable, especially for extended-time wearers or every-day wearers. Facial masks which are held against the face by ear straps often have “air gaps” around the edge of the mask, allowing unfiltered air to enter in or out of the wearer. One solution has been to pull the mask tighter against the face, which does create a better seal/smaller gaps, however wearing a tight face masks typically makes the face mask less comfortable to wear and can leave impression marks in the skin.

Thus, the problem with most of these masks is that they do not create a complete facial seal meaning that the virus can still exit or enter the mask because there is not a complete facial seal. Furthermore, most of these masks use straps that go around the ears of the user or the back of the head of the user which is uncomfortable and results in people removing the mask at the wrong times (such as when still inside in an enclosed area with a large number of other people) or not wearing the mask at all. Thus, it is desirable to provide a mask that do not require straps and seals the face.

There have been other uses for an adhesive to adhere an item to the skin of the user. For example, nasal strips meant to open the nasal passages or strapless brassieres use some form of adhesive to adhere to the skin pull the skin up on the nose and thus open the nasal passages. The adhesive on a strapless brassiere adheres to the skin and keeps the brassiere up and covering the breasts of the wearer. None of the uses however, have contemplated using an adhesive for other purposes.

In certain situations, it is desirable to have the above mask that uses adhesives to completely seal the face region that is a single use and then discarded. For example, when a user visits a business or doctor and forgets their mask, it would be ideal to be able to provide a disposable, single use mask to the user and thus, it is desirable to provide a single use facial mask that uses a weak adhesive to completely seal the face and it is to this end that the disclosure is directed.

DETAILED DESCRIPTION OF ONE OR MORE EMBODIMENTS

The disclosure is particularly applicable to a face mask that is meant for a single use for protection against Covid 19 and it is in this context that the disclosure will be described. It will be appreciated, however, that the mask may be manufactured of different materials, have different sizes or shapes and have other features that are all within the scope of the disclosure.

The disclosure is directed to a facial mask that completely seals the areas of the face that improves wearing comfort, avoids ear irritations, and creates a complete seal of the mask against the face. The facial mask may be implemented for both non-medical grade (cloth) masks and/or medical-grade (N95 or similar) masks. Furthermore, different materials can also be utilized with this invention to achieve disease-spread-reducing, particulate filtering, fume-reducing, or other goals/criteria. Now, several examples of embodiments of the facial mask will be described.

FIGS. 1A and 1B illustrate a first embodiment of a facial mask 100 shown being worn by a user. In this embodiment, the mask 100 covers only the mouth of the user. The mask has a covering portion 102 that filters the air being inhaled and traps particulate and droplets being exhaled by the user through the mouth. Examples of the particular material and one or more layers of the covering portion 102 are described below in more detail. As shown in FIG. 1B, an adhesive 104 encircles the mask near the edge of the mask. Note that the precise distance of the adhesive 104 from the edge of the mask can vary somewhat and a width of the adhesive can vary between about 0.25 inches to 1 inch. In one embodiment, the adhesive is 0.75 inches wide all of the way around a perimeter of the mask. The adhesive may be a weak adhesive (an adhesive that is semi-adhesive allowing the wearer to put-on/take-off or reposition the mask one or more times) and may be in the form of a strip of adhesive that is affixed to the covering portion 102. For example, the adhesive may be double sided and one side is stuck to the covering portion 102, the adhesive may be sewed to the covering portion or attached to a hook and loop structure, such as Velcro or similar material with the purpose of the hook and loop or similar fastener allows the facial mask material/covering to be temporarily remove/replaced by the wearer, with the tape/adhesive continuing to be attached to the face (for example to eat a meal or take a drink). The first side of the adhesive does not release from the covering portion 102 while the other side adhesive is pressed onto the face to secure the mask to the face. When the mask 100 is placed over the mouth of the user, the adhesive 104 sticks to the skin of the user to completely seal the mouth of the user. The adhesive may be manufactured such that it can be easily removed from the face of the user and then replaced onto the face of the user without significantly degrading the stickiness. In one embodiment, the adhesive strip is a commercially available product number 2477P that is manufactured by 3M although the mask may be manufactured using other adhesive strips/tapes.

FIGS. 2A and 2B illustrate a second embodiment of a facial mask 200 shown being worn by a user. In this embodiment, the mask 200 covers both the nose and mouth of the user. The mask has a covering portion 202 that filters the air being inhaled and traps particulate and droplets being exhaled by the user through the mouth and/or nose. Examples of the particular material and one or more layers of the covering portion 202 are described below in more detail. As shown in FIG. 2B, an adhesive 204 encircles the mask near the edge of the mask and the distance from the edge of the mask may vary somewhat.

The adhesive may be a weak adhesive and may be in the form of a strip of adhesive that is affixed to the covering portion 202. For example, the adhesive may be double sided and one side is stuck to the covering portion 202, the adhesive may be sewed to the covering portion or attached to a hook and loop structure, such as Velcro or similar material with the purpose of the hook and loop or similar fastener allows the facial mask material/covering to be temporarily remove/replaced by the wearer, with the tape/adhesive continuing to be attached to the face (for example to eat a meal or take a drink). The first side of the adhesive does not release from the covering portion 202 while the other side adhesive is pressed onto the face to secure the mask to the face. When the mask 200 is placed over the mouth and nose of the user, the adhesive 204 sticks to the skin of the user to completely seal the mouth and nose of the user. The adhesive may be manufactured such that it can be easily removed from the face of the user and then replaced onto the face of the user without significantly degrading the stickiness as above.

FIGS. 3A and 3B illustrates a third embodiment of a facial mask 300 shown being worn by a user. In this embodiment, the mask 300 covers both the nose and mouth of the user. The mask has a covering portion 302 that filters the air being inhaled and traps particulate and droplets being exhaled by the user through the mouth and/or nose. Examples of the particular material and one or more layers of the covering portion 302 are described below in more detail. As shown in FIG. 3B, an adhesive 304 encircles the mask near the edge of the mask and the distance from the edge of the mask may vary somewhat. In this embodiment, there may also be another piece of adhesive between the nose and mouth for stability.

The adhesive may be a weak adhesive and may be in the form of a strip of adhesive that is affixed to the covering portion 302. For example, the adhesive may be double sided and one side is stuck to the covering portion 302, the adhesive may be sewed to the covering portion or attached to a hook and loop structure, such as Velcro or similar material with the purpose of the hook and loop or similar fastener allows the facial mask material/covering to be temporarily remove/replaced by the wearer, with the tape/adhesive continuing to be attached to the face (for example to eat a meal or take a drink). The first side of the adhesive does not release from the covering portion 302 while the other side adhesive is pressed onto the face to secure the mask to the face. In an alternate embodiment, the adhesive, such as a skin-friendly adhesive, may be sprayed or otherwise deposited onto the skin of the face of the user or directly onto the mask material so that the mask may be completed sealed onto the face of the user. In this alternative embodiment, no adhesive tape/strip is needed to achieve the complete face sealing.

This embodiment of the mask 300 also may have a wire mesh attached into the mask, such as sewn into around the edge of the mask, to provide shape-forming rigidity to the mask 300. Alternatively, other materials that provide shape forming, such as silicone, plastic, etc., may also be used. In addition to the shape forming rigidity, the wire mesh or other materials may be used to keep the mask cloth/filter off of the lips of the user (to avoid touching lipstick, make it easier for the user to breath or talk, etc.).

When the mask 300 is placed over the mouth and nose of the user, the adhesive 304 sticks to the skin of the user to completely seal the mouth and nose of the user. The adhesive may be manufactured such that it can be easily removed from the face of the user and then replaced onto the face of the user without significantly degrading the stickiness.

FIGS. 4A and 4B illustrate a fourth embodiment of a facial mask 400 shown being worn by a user. In this embodiment, the mask 400 covers both the nose and mouth of the user. The mask has a covering portion 402 that filters the air being inhaled and traps particulate and droplets being exhaled by the user through the mouth and/or nose. Examples of the particular material and one or more layers of the covering portion 402 are described below in more detail. As shown in FIG. 4B, an adhesive 404 encircles the mask near the edge of the mask and the distance from the edge of the mask may vary somewhat. This embodiment of the mask 400 as shown in FIG. 4A may have one or more additional adhesive anchor points 406, such as the three shown near the two lower corners and near the middle/top of the nose, where a limited adhesive area anchors (attaches) the mask to the face. Alternatively, this embodiment may be attached to the face by just the one or more anchor points 406. The limited number of anchor points 406 allows for the maximum mouth/facial movement (underneath the mask) for talking, eating, or comfort reasons and the facial mask would continue to cover additional parts of the face on a free-floating (non-adhered) basis.

The adhesive may be a weak adhesive and may be in the form of a strip of adhesive that is affixed to the covering portion 402. For example, the adhesive may be double sided and one side is stuck to the covering portion 402, the adhesive may be sewed to the covering portion or attached to a hook and loop structure, such as Velcro or similar material with the purpose of the hook and loop or similar fastener allows the facial mask material/covering to be temporarily remove/replaced by the wearer, with the tape/adhesive continuing to be attached to the face (for example to eat a meal or take a drink). The first side of the adhesive does not release from the covering portion 402 while the other side adhesive is pressed onto the face to secure the mask to the face.

This embodiment of the mask 400 also may have a wire mesh attached into the mask, such as sewn into around the edge of the mask, to provide shape-forming rigidity to the mask 400 that can fit to the 3 dimensional shape of the face. When the mask 400 is placed over the mouth and nose of the user, the adhesive 404 and/or anchor points 406 sticks to the skin of the user to completely seal the mouth and nose of the user. The adhesive may be manufactured such that it can be easily removed from the face of the user and then replaced onto the face of the user without significantly degrading the stickiness.

Each of the embodiments shown in FIGS. 1A-4B do not require straps to secure the mask to the face of the user. However, each of these masks 100-400 may also include straps or may have holes in the mask 100-400 to accommodate a strap. Alternatively, the mask may also have loops or other similar methods to connect an optional strap to the mask.

Furthermore, each embodiment of the mask may have different sizes to accommodate different size and shape faces. For example, the facial mask may have an overall circular, elliptical, oval, square, and/or elliptical shape with both sides curving upwards (to approximate a smile shape), or in any other shape, for example to visually create a company logo (for example a circular body with two “ears” in the upper corners—for example to appear as mouse with two ears shape). As shown in the above figures, the mask may be a single piece or made from two pieces. Also, each embodiment may have advertising on an outside surface of the mask, an image and/or writing on the outside of the mask. Thus, in different embodiments, the mask may have a consistent color across the outside of the mask, different colors, designs, patterns, etc. on the visible-to-the-world side of the mask. For example, the outer surface of the mask may have cosmetic patterns, colors, and shapes, such as a brand or company logo, patterns, or shapes.

Each of the above masks and the mask shown in FIGS. 5-6 may be made using a double sided adhesive tape as disclosed above. Alternatively, an adhesive may be poured onto the mask to form the adhesive that adheres to the face of the user. In some embodiments, the adhesive may be flexible and stretchy so that, for example, a user can open his/her mouth and the mask will remain attached to the face of the user. In some embodiments, the silicon adhesive may be stretchy although the amount of stretch may be dependent on the tape material itself.

In some embodiments, the mask may have the adhesive or “tape” on the outside-side of the mask, positioned such that the single-sided tape approximately half covers the facial mask material, with some of the tape extending beyond the edge of the mask, allowing the tape material to then adhere to the skin outside of the area covered by the facial mask material.

Each of these masks 100-400 may be made of a typical mask material, such as a fine mesh of synthetic polymer fibers, such as a nonwoven polypropylene fabric. Each mask 100-400 may also be made of a cloth material and may have one or more folds in the mask that allows the mask to expand to accommodate a wider range of face sizes or to accommodate stretching/expansion of the mask. Alternatively, each mask 100-400 may be made of material that itself may contain one or more folds to accommodate stretching/expansion.

Each of the embodiments of the mask above or shown in FIGS. 5-6 may be transparent, semi-transparent and/or not-transparent. In various embodiments, the facial mask and the adhesive may be water-proof or water-resistant to allow the wearer to wear the mask in the rain, etc. In another embodiment, the facial mask along with the adhesive/adhering mechanism is not water-proof or water-resistant.

In one embodiment, any of the masks may be folded/sewn in areas so the facial mask may be shipped/stored flat or minimal height. Then, when the mask is applied to the face the folded areas unfold to better cover to the typical contours of the nose/mouth of the user. The masks may have a Caucasian skin color on an outside surface of the mask. In other embodiments, the mask may come in different colors to better blend with black, dark, or other colors and shades to match the wide-variety of human face color/tones.

FIG. 5 is a front view of an exemplary mask 500. This mask may be made of a cloth material and may have one or more folds that allows the bottom of the mask 500 to adjust in size. In this embodiment, an adhesive strip 504 may encircle the mask 500 to seal the mask to the face and the adhesive strip may be 0.75″ wide and may be very close to the edge of the mask. The placement of the adhesive 504 provide a sealed pocket inside of the mask in which the nose and mouth of the user are located. FIG. 5 also shows an example of advertising being placed on the outside of the mask surface.

Now, three embodiments of the single use mask that cover the nose and mouth of the user will be described with reference to FIGS. 6-8. It is understood however, that the single use mask may be manufactured as shown in FIGS. 1A-1B, 3A-3B and 4A-4B above.

FIG. 6 illustrates a first embodiment of the single use mask in which the single use mask has a single layer 600 of filter material (which could itself contain one or more internal layers like a filter stack for a multiuse mask version that has an anti-sticking cloth, a first stage filter, an activated carbon layer, a second stage filter and a second anti-sticking cloth that are stacked together). In addition, or alternatively, the filter material 600 could be additional forms of filters, have any of one or more layers. Furthermore, the filter material 600 may be electro-cloth filters, nano-filters, HEPA filters, silver-based filters, etc.

The mask may also have an adhesive layer 602, such as well known and commercially available double sided adhesive tape, so that the mask may be directly attached to the face as shown in FIG. 6. In the example in FIG. 6, the adhesive layer 602 may be formed as a continuous loop in the shape of the mask, but it may also be formed of several pieces of adhesive each of which does not form a closed loop as shown in FIG. 6.

FIG. 7 illustrates a second embodiment of the single use mask that has the same elements as FIG. 6 (layer 600/700 and adhesive layer 602/702) in which the single layer 700 may be a fabric material that may also still have filter stack as described above.

FIG. 8 illustrates a third embodiment of the single use mask 800. This embodiment of the single use mask 800 may have a layer 801, an adhesive layer 802 and a cover 804 that encapsulates the layer 801. The cover 804 may have graphics/logos/advertisements/text on the surface pointing away from the user. The cover 804 may also be made of different colors. The cover 804 may be attached to layer 801 using stitching, glue, ultrasonic welding, plastic or metal staples, or other similar forms of bonding or attaching multiple materials together. The cover 804 may also include one or more folds or may be folded over around the edges of layer 801, or layer 801 may include one or more folds, or may be folder over around the edges of cover 804.

In an alternative embodiment, the single use mask may have a filter layer (either a single layer or a sandwich comprised of multiple internal layers) that is attached to a region of the face using an adhesive, such as a silicon adhesive, that is sprayed or other deposited onto an outer perimeter of the filter layer/mask and then adhered to the face without the need for adhesive tape and with only a single layer of silicone adhesive. In this embodiment, the outer perimeter of the mask contains the adhesive, with the main inner portion of the mask being the breathing/filter material and an outer 0.75 wide perimeter, all the way around the mask (the area shown inside the two dotted lines) is where the spray adhesive is applied. This alternative embodiment of the mask is very thin/flat, and the adhesive portion is a thin material which holds the mask in place (similar to the adhesive in a band-aid).

In all of the embodiments, the center portion of the mask (the breathing portion) may be straight/flat or may contain an excess (folded) amount of mask/material, to accommodate for opening of the mouth, talking, and/or to position the mask/filter material slightly in front of the lips/mouth to assist with breathing. Alternatively, some mask materials may be semi-rigid and the mask material could have a slight outward protrusion to keep the mask/filter material slightly ahead/in front of the lips, to help avoid the lips from touching the mask/filter material, to increase comfort.

As an alternative embodiment to the embodiments shown above in which the adhesive bond/strip goes around the periphery of the mask, the mask may form a complete face seal with the combination of adhesives and other materials. For example, the mask may have a combination of adhesives in some portions of the face-to-mask seal and non-adhesive but air-blocking insulators (1-sided sticky foam for example) in other parts. For example, the mask forms the tight, complete seal in which adhesives are used for some portions of the seal as it goes around the face and then the insulators, such as piece of foam with one side having an adhesive to adhere to the covering, may be used to “fill in the gaps” between sections of adhesive as the seal goes around the face. As another alternative, the adhesives form an incomplete face seal to hold the mask on to the face, but not necessarily to form an air-tight seal. For example, there could be 4 or 5 adhesive points which hold the cloth covering on to the face and holds it in place over the nose/mouth, and forms a majority seal but not necessarily an “air tight” seal.

In some embodiments, the mask may include one or more valve or other air-flow limiting or switching device (to allow for greater unidirectional airflow rates). In some embodiments, the facial mask covering may extend over the skin slightly past the adhesive area/region to allow for a finger to easily grab this extra “tab” to allow easy mask removal from the face. For example, such a tab be placed along the bottom (chin-facing) side of the mask.

In some embodiment, the facial mask have “shape forming” material added to, in, formed on or attached to the face mask covering material, to aid in the covering conforming to either a pre-formed shape (i.e. the 3 dimensional shape around the nose), or user-conformed shape. Such “shape forming” forming materials may be continuous, semi-continuous, or limited (strips), in one multiple directions (for example in a mesh combined of multiple strips in parallel and/or different directions) to allow the user to conform (custom shape) the mask to a rigid, or semi-rigid, or shape to customize the mask to conform to that user's face shape. Such “shape additive” material could be composed of one or more metal areas, wire mesh (similar to a metal wire fence) metal, plastic, or other bendable materials, either pre-formed at the factory to a standard facial shape, or with user-formable materials to allow the user to custom-shape the semi-rigid material to the custom size/shape of his/her face.

In some embodiments, the facial mask may have one or more “hinge points” added to the filtering material, on, or attached to the face mask covering material, to aid in the temporary lift up/away from the mouth, for purposes of eating, drinking, talking on the phone, etc. The facial mask may have any combination of one or more of the above shapes, colors, valves, and/or features, elements, adhesives or adhesive mechanisms.

FIG. 9A illustrates the facial mask with hinge in a normal wearing position and FIG. 9B illustrates the facial mask with hinge in a folded up position. The facial mask 900 may have a horizontal crease 904, that may be pre-folded, approximately halfway down the mask 900 and one or more attachment mechanisms 902, 903, such as hook and loop materials, such as 3M branch Velcro or other attachment mechanisms that are attached to the mask and used to hold the mask in the folded up position as shown in FIG. 9B (to allow eating or drinking, etc. by the user without having to completely remove the facial mask). The horizontal crease 904 allows the mask material to easily fold at the crease line. The attachment mechanisms 902, 903 are attached to the mask in positions such that when the lower-half of the mask is folded in the “folded up” position, along the crease line, that the two piece of the attachment mechanism 902, 903 (as shown in FIG. 9B) connect with each other and hold the lower half of the mask up against the upper half of the mask, enabling the wearer to eat or drink, exposing this mouth. In some embodiments, there may be one or more attachment mechanisms.
