The present invention relates to facial personal protective equipment. More particularly, the invention relates to facial protective equipment which requires no ties or elastic bands to operatively engage facial protection to the face of the user, as well as a system for the wide and easy deployment of such facial protective devices from conventional rolled dispensers or boxes.
When dealing with a highly infectious disease which is easily passed from person to person, the wearing of personal protective equipment (PPE), such as facial masks and/or shields, is recommended. The wearing of such PPEs has been shown to prevent the expelling and inhaling of airborne viruses and bacteria and the like. Such face coverings, when worn properly, provide a first line of defense for the airborne transmission of diseases.
Shield type protective face coverings conventionally employ a substantially transparent shield positioned in front of the face and eyes of the wearer. The transparent shield, so positioned, forms a barrier to the communication of pathogens in the air surrounding the wearer from reaching the eyes, nose and mouth of the wearer. Such shields are conventionally held in place by a headband engaged to an upper end of the deployed shield.
Flexible nose and mouth coverings, in the form of fabric type masks, are conventionally worn in a contact with the face of the user in a position to cover the nose and the mouth of the wearer. These flexible coverings conventionally employ a tight mesh which will pass air to and from the nose and mouth of the user but which will substantially prevent the passage of droplets of atomized fluids, which the wearer might breathe, from surrounding air. Further, they also prevent the wearer from projecting such fluids into the air where others may come in contact with them.
Such flexible coverings are well known and conventionally employ elastic straps or straps which the user may tie once the mask is properly positioned. They may also be layered and include filter materials adapted to catch and destroy pathogens which may be airborne or might become airborne upon a cough or sneeze of the wearer.
In some cases, it may be desirable for a user to employ both a clear protective shield, which covers a face mask, to protect themselves and others from potential infection. Such will provide both a clear shield which will help to protect the eyes from airborne pathogens and the flexible mask which will filter such and prevent airborne transmission.
However, making such face shields and/or masks available, in a convenient fashion to users, is a significant problem. Travelers in airports, visitors to buildings and medical centers, meetings, or even concerts, all must either bring their own facial protection or depend on the venue which they are visiting to provide it. Such is not conducive to maximizing the wearing of such protection to minimize the potential of passing pathogens to visitors.
The forgoing examples of related art in facial coverings and limitations related therewith are intended to be illustrative and not exclusive, and they do not imply any limitations on the system for deploying facial protective coverings described and claimed herein. Various limitations of the related art will become apparent to those skilled in the art upon a reading and understanding of the specification below and the accompanying drawings.
The system herein disclosed and described provides a solution to the shortcomings in prior art in PPEs used for facial covering. The system herein provides for easy deployment of and encouragement of the use of protective facial coverings which help to provide an impediment to the spread of pathogens. The system herein achieves such through the provision of facial coverings in the form of substantially transparent flexible face shields and air-filtering masks. Such may be dispensed from containers such as boxes or other holders, or they may be positioned in rolls, thereof, in existing conventional towel dispensers and similar dispensing equipment.
The system herein provides the option for a two-stage PPE for the user. One mode includes air filtering facial masks and/or wearable substantially clear face shields individually, or the masks and face shields may be combined to enhance the protection of the user. The flexible masks may be dispensed individually from a stack or box or from a plurality of individual face shields whereby individual shields may be dispensed sequentially from a dispensing component. In another mode of dispensing the flexible air filtering masks, they may be dispensed from a roll thereof having frangible connections.
For the face shields, such have a body formed of a layer of substantially clear polymeric or plastic material through which the user can easily see their surroundings once positioned on the face of the user. The face shields may be dispensed individually from a stack or a plurality thereof in a container such as a box. Also, and particularly preferred for ease of dispensing, because the polymeric bodies in a stack tend to sick together, is the formation of rolls having a plurality of shields in individual which are rendered separable from the dispensing roll by a specially configured frangible edge.
In use, a shield or mask may be removed from a stack thereof in a box, or in one mode of the system, they may be pulled from a roll thereof where the individual shields tend not to stick together. The shields, in a particularly preferred mode of the system, may be dispensed from rolls which are rotationally engaged in a housing, such as a conventional paper towel dispenser. Where such dispensers will automatically dispense a face shield or in some cases a face mask from a roll, the individual face masks or face shields will automatically project from the dispenser housing once a button is pressed or a proximity switch is actuated by a user.
Preferably, each face shield or mask is held in a clean container, or where required, a sterile container. Where sealed in a sterile container, such as paper or plastic bag like containers, that container is easily opened by the user to allow the user to remove the mask or face shield from a sealed cavity within the container. However, because such face shields and filtering masks are conventionally employed in a fashion not requiring total sterility, they may simply be dispensed without coverings with more convenience such as from stacks or rolls thereof.
Additionally preferred in all modes of the system, is the provision of such air-filtering face masks and such protective shields, in a form which requires no headbands, straps, or elastic, to operatively position it on the face of the user. Instead, the face shields herein are provided with adhesive sections located thereon, which are adapted in position to adhesively engage the face, such as preferably the temple area of the face of a user. Such adhesive may be a double adhesive with a protective release layer on each.
In an alternative mode of the face shields, an aperture defined by a slit formed in opposing mounting areas on the body of the face shield are adapted to hold the face shield in place through a frictional engagement on the temples of eyewear. Experimentation has found that a slit defining the aperture worked better then a hole, because the plastic material on both sides of the slit form a frictional, substantially non slip engagement on the temples of the eyewear of the user. This frictional engagement better holds the transparent shield in a curved positioning in front of the face of the user. In either mode of facial engagement of the face shield to the user, no straps or ties or elastic are required which are or can become uncomfortable over long hours of use.
The air filtering face masks are likewise provided with a mask body formed of air filtering fabric or material which is well known and widely employed. The face mask body has a shape and perimeter area which has one or preferably a plurality of annular adhesive areas positioned around the perimeter area of the mask body formed of the air filtering material forming the mask body. The adhesive is in locations adapted to adhesively engage the perimeter area of the mask body to the cheeks of the user, and the jaw or neck of the user. By perimeter area herein is meant an area between an inner edge of a first adhesive area and the exterior perimeter edge of the face mask body.
In the particularly preferred mode of the face masks herein, a first adhesive area surrounded by a second adhesive area is provided. This allows users to remove the mask temporarily and where the first adhesive area may have become unuseable, the second adhesive area may be exposed and provide a secondary adhesive connection to the face of the user. As with the face shield, no strings or elastic straps are required to hold the face mask in position on the face of the user.
Additionally provided, by such an adhesive engagement of the masks to the face of the user, is a sealed connection over the bridge of the nose of the user, without the need for a wire or the like as in conventional face masks. The first and second adhesive areas are shaped with an arched area, which has been found in experimentation to provide an especially good seal when engaged to the face of the user over the bridge area of the nose. This substantially air tight seal helps prevent air leakage as well as fogging of eyewear and drying of the eyes of the user caused by long term airflow which occurs with conventional unsealed protective facial masks.
With respect to the above description, before explaining at least one preferred embodiment of the herein disclosed protective face covering system in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangement of the components in the following description or illustrated in the drawings.

The dispensed face shields 14, as shown in
The face shields 14 may be dispensed from a plurality thereof, such as a stack of face shields 14 of the system 10 herein, which may be dispensed from such a stack held in a container, such as a box 17 or the like. Alternatively, and as noted and preferred, to keep the face shields 14 from sticking together, such as with static attraction in a stack, the face shields 14 may be dispensed from a roll 18 thereof, which has a plurality of face shields 14 having a tearable or frangible connection 22 between a first end of one face shield 14 and a second end of the engaged face shield 14.
The roll configuration of
This ease of detachment was found best when the three connectors 23 were between 0.5 mil to 1.5 mils wide, and the transparent plastic or polymeric material forming the shield body is between 4-10 mils in thickness. While a lesser number of connectors 23 may be employed, or another frangible or tearable attachment to achieve the roll 18 dispensing of the face shield 14, the easiest defacement with the least damage or folding or creasing of the adjacent shield bodies 15 was achieved with the three connectors 23 and gap 21 as described.

Each of the first adhesive area 38 and second adhesive area 39 are configured to form an annular or ring-like seal around substantially an entire perimeter area of the face mask 16 face body 19 to form a sealed attachment to the face of a user 46. The face mask 16 can be straplessly connected in a first configuration, such as in
The user 46, thus, removes the face mask 16 temporarily such as for a work break or eating or such, and if the face mask 16 will not adequately form a seal around the perimeter area 54, the second cover 50 may be removed from the second adhesive area 39, and the face mask 16 can be reengaged with substantially a sealed engagement to the face of the user 46 around the perimeter areas 54 provided by the second adhesive area 39 in combination with the first adhesive area 38. This mode of the face mask 16 is especially preferred as a means to use less face masks 16 at venues using them since the sealed engagement around the perimeter area 54 can be renewed.
While shown as annular or ring like formations completely encircling the perimeter areas 54 of the face mask body 19 of air filtering material, to thereby prevent air from circumventing it, there could be small gaps therein and still yield a strapless connector to the face of a user 46 which allows for removal and re engagement once the second cover 50 is removed from the second adhesive area 38. However, where such may occur or be configured, the second adhesive area 39, surrounding the interior located first adhesive area 38, will generally still provide a sealed engagement to the face of a user 46 that will prevent passage of air around the filtering fabric forming the face mask body 19.
Additionally preferred, in all modes of the protective face mask 16 portion of the system 10, whether used alone or in combination with a shield, is the curved recess 56 formed into the interior edge of and defining a central portion of the first adhesive area 38. An enhanced sealed engagement of the first adhesive area 38, over and around the bridge 60 of the nose of a user, was found after much experimentation to be yielded by this curved recess 56 formed into the interior edge of the first adhesive area 38.
