     BACKGROUND 
       [0002]    Dust masks are well-known devices that are typically used in industrial, medical or other situations to protect a user from inhaling unwanted air-borne particles such as drywall dust, paint molecules, viruses, etc. Lightweight dust masks are also well-known, and are configured to cover the nose and mouth of a user, typically held to the user&#39;s head by an elastic band.  FIG. 6  depicts such a mask  102  on the head of user  104 . The mask  102  comprises relatively thin elastic straps  108  and does not cover the ears  110  of the user. Such masks, therefore, leave the ears vulnerable to the unwanted particles, are uncomfortable to wear, may not remain in a desired position on the user&#39;s face, and otherwise do not protect the user as effectively or comfortably as may be desired. 
         [0003]    Thus, there has gone unmet a need for improved dust mask devices, systems, methods, etc., that protect the ears, stay in place better, and/or are more comfortable. The present systems and methods, etc., provide one or more of these and/or other advantages. 
       SUMMARY 
       [0004]    The present devices, systems, methods, etc., provide lightweight dust masks that cover all of the mouth, nose and ears of the user, thereby protecting the user&#39;s hearing and keeping the ears clean without restricting the hearing ability (unless sound protection is also desired, in which case sound reducing materials and/or configurations can be provided). The masks are substantially continuous from ear to ear and can be a simple unitary design (i.e., the mask is not only continuous from ear to ear but at least one ply of the layers of material making up the mask extends from ear to ear without a break). The masks typically comprise multiple layers of protective material plus one or more straps, resilient ear “hooks” or other retaining devices to comfortably and securely hold the mask in place. The mask can also comprise, if desired, an exhalation vent and rigidity elements such as a nose bridge. 
         [0005]    The masks can be made out of the same materials that prior dust masks are made from, and/or of other materials such as activated carbon for use with different chemicals and particles.

     DETAILED DESCRIPTION 
       [0033]    Turning first to the Figures for a discussion of the exemplary embodiments shown therein,  FIG. 1  depicts a side view of a dust mask as discussed herein wherein mask  2  comprises a body  10  comprising a front piece  12  configured to cover the nose and mouth of the user and an earpiece  14  configured to cover the ears of a user (only one of the earpieces  14  is shown in  FIG. 1 ). The body  10  of the mask  2  is substantially contiguous and sized and configured to extend from ear to ear and to substantially cover all of and only the mouth, nose and ears of the user. Typically, the mask  2  is lightweight and disposable so that it is relatively inexpensive, and can be provided in easily stackable, easily packable groups so that a user can use one until it becomes fouled by air-borne particles such as dust, paint spray, medical detritus, etc., then the user can easily remove the mask, throw it away into an appropriate receptacle, and then replace the mask with a readily available replacement mask. 
         [0034]    The materials comprising the mask can be any appropriate materials and are typically selected for the particular use for which the mask is intended. For example, in an industrial situation, such as a manufacturing plant or an auto body painting or fiber glass shop, the mask is typically made of paper or plastic and configured to filter out air-borne particles of a certain size that is likely to be found in that environment (for example, paint droplets or molecules, fiber glass particles, or dust from materials such as metal, wood, glass, stone, etc., that are being machined). In the situation where the mask is to be used for medical situations such as surgery or immuno-compromised care, or certain high-tech situations such as clean rooms where absolute cleanliness and/or sterility are important, the mask is made of sterilized and/or completely non-dust-emitting materials so that the mask does not introduce any unwanted pathogens, contaminants, etc., into the operating environment. 
         [0035]    Still referring to the exemplary embodiment in  FIG. 1 , the mask also comprises at least one retaining device configured to hold the mask in place on the user. In the embodiment of  FIG. 1 , the retaining device is two straps  8 , each contains a snap  6  with the opposing straps or retention locations on the other side of the mask comprising corresponding snaps to receive snaps  6  and securely hold mask  2  to the head of the user (the head of the user is not shown in  FIG. 1  is but shown, for example, as user&#39;s head  4  in  FIGS. 7 and 8 ). The mask  2  can, if desired, include an exhalation vent  16  which is typically located at substantially the front  18  of the mask where the user&#39;s nose and mouth are located. Earpiece  14  can comprise an ear bulge  20  so that it more comfortably fits around the user&#39;s ear. If desired, the earpiece  14  can further comprise materials that are particularly suited for the ear, such as soft materials that do not irritate the ear, sound deadening materials to protect the ear from ambient noise such as industrial levels of noise such as jackhammers, milling machines, high pressure paint sprayers, etc. Such materials can be incorporated into ear bulge  20  advantageously, although they can also be used without a bulge for the ears. 
         [0036]    As depicted in  FIG. 1 , in certain embodiments the retaining devices are thick straps  8  which can be made of the same material as the dust mask or of a different material. Thus, either or both the ear pieces or substantially the entire mask can be made of an elastomeric material that stretches to adapt to the particular configuration of the individual user&#39;s head. By providing wider straps than the typical thin rubber bands depicted in  FIG. 6  showing the prior art, the straps can be more comfortable and also hold the mask more securely in place on the user&#39;s head, thereby reducing both discomfort and the likelihood that the mask will slip or not fit properly thereby permitting unwanted air-borne particles to enter the user&#39;s ears, nose and mouth. 
         [0037]    As depicted in exemplary embodiment in  FIG. 1 , the periphery of the mask can be ridged, thickened or comprise an additional material such as an elastomeric material (typically wrapped within a material more comfortable for the user) to provide a peripheral ridge  24  that extends along all or a desired portion of the mask  2 . This ridge can be configured to aid, for example, in improved comfort for the user by providing a more snug fit that conforms to the individual characteristics of the individual face of the user, as well as improved safety characteristics by providing an improved fit to the user. If desired, the periphery can comprise different materials or characteristics at different locations, for example, the lower edge  26  of the mask may be elastomeric while the upper edge may provide a thickened, rigid portion. 
         [0038]      FIG. 2  depicts an additional exemplary embodiment of a dust mask  2 . The dust mask in  FIG. 2  is similar to the dust mask in  FIG. 1  except the straps  8  comprise a hook and loop connector fabric such as VELCRO® on the ends of the straps. Mating hook and loop connector fabric pieces are on the opposing straps or opposing side of the mask or other suitable location, so that there are mating male and female sides of a hook and loop connector fabric configured such that the straps can be easily passed around the head of a user and lengthened or shortened to fit the particular head of the user. As with the embodiment in  FIG. 1 , the bottom periphery or lower contour  30  snugly and firmly fits under the chin of the user then trails up the neck to surround and cover the complete ear of the user. In the embodiment in  FIG. 2 , the lower strap departs from a lower lateral region  32  while a second, upper strap  26  departs from an upper lateral edge  34  of the body  10  of mask  2 . Further, the embodiment in  FIG. 2  comprises a resilient nose bridge  28  and a resilient nose chin piece  52 . 
         [0039]    Mask  2  in  FIG. 2  further comprises at the front  18  of mask  2  an exhalation vent  16 . Such vents are well-known and are configured to ease and/or improve the inhalation and exhalation by the user, and/or to improve filtration of unwanted particles if desired. For example, while the entire body  10  of mask  2  can be porous, if desired only the exhalation vent  16  can be porous while the remainder of body  10  can be either porous or substantially or completely impermeable. Further, if desired, exhalation vent  16  can comprise one or more exchangeable filters or filter elements such as activated carbon cartridges, etc. 
         [0040]      FIG. 3  depicts a top view of a mask as discussed herein wherein the mask, as also depicted in  FIG. 2 , comprises a resilient nose bridge  28 . The resilient nose bridge can, if desired, be deformable, for example via the use of metal, so that it can be adjusted by the user to configure to the individual shape of the individual user&#39;s nose and face. Conversely and/or in addition, the resilient nose bridge can provide structure to the mouth and nose area of the mask so that the bulge about the user&#39;s nose and mouth is maintained even under relatively difficult conditions such as high wind or pressure or anticipated external contact. In the view in  FIG. 3 , the ear bulge  20  of earpieces  14  can be more readily seen than in some of the other figures herein. 
         [0041]      FIG. 4  depicts a dust mask  2  comprising a substantially unitary, substantially continuous body  10  wherein the dust mask  2  does not comprise an exhalation vent  16  and thus at least a portion of the body  10  of the dust mask  2  is porous and semi-permeable so that air and other desired elements can pass through the mask while particles and undesired elements cannot. Further, in  FIG. 4 , the dust mask  2  does not comprise straps as depicted in other figures but rather comprises a resilient ear hook  36 , depicted in broken line as it is embedded in this embodiment within the earpiece  14  of the dust mask  2 . The ear hook  36  is configured to wrap around the ear of the user and thereby hold the dust mask to the head of the user without the need for straps or additional structures. If desired, a given dust mask can have both ear hooks and straps, or other retaining devices as desired. 
         [0042]      FIG. 5  depicts a rear view of only the earpieces  14  of a mask  2 , the earpieces  14  connected by a unitary strap  38 . In  FIG. 5 , the unitary strap  38  extends from the lower lateral regions  32  and upper lateral regions  34  of the earpieces  14  of the mask. In the embodiment depicted, the legs  40  of unitary strap  38  meet at a center  42  which in the embodiment depicted is a hollow circle. One advantage of this configuration is that the strap can be permanently affixed to the sides of the dust mask  2  so that a user need merely slip the dust mask over his/her head, without having to also attach straps to each other. Typically, the unitary strap  38  is made of an elastomeric material so that it can adapt to the size of an individual user&#39;s head. 
         [0043]      FIG. 7  depicts a side view of a dust mask in place on the head of a user, the depiction in silhouette. In the embodiment shown, a first retaining strap extends between opposed, substantially lateral edges of the mask and substantially behind the head of the user, while a second retaining strap extends between or about the opposed, substantially upper lateral edges and extends substantially over the head of the user. This configuration can advantageously hold the dust mask  2  to the face of the user with improved comfort and conformation of the mask to the face of the user. The strap configuration in this Figure, comprising broad straps that both depart from an upper lateral area  34  of the body  10  of mask  2 , as opposed to the bulk of the embodiments and aspects discussed herein, can be advantageously used in dust masks that do not reach all the way to the ears. Further, in this embodiment instead of or in addition to an exhalation vent in other figures, the mask  2  comprises a respirator  54 . 
         [0044]      FIG. 8  depicts in silhouette a mask  2  as discussed herein on the head of a user  4 . In this embodiment, the upper contour  46  of the mask  2  has been specifically conformed to match the lower margin  48  of eye protection device  44  so that the lower margin  48  and the upper contour  46  match well together to provide improved protection for the user. In certain embodiments herein, the devices, systems, kits, etc., as well as methods of making and using, can comprise making, providing and/or using both the dust mask  2  with the correspondingly configured eye protection device  44 . For example, a single kit may comprise multiple dust masks  2  along with one of the eye protection devices  44 . Replacement dust masks  2  can then be sold or otherwise provided to the user to be used specifically in conjunction with a particular eyewear  44 . 
         [0045]      FIGS. 9-12  depict front plan views of various embodiments of the dust mask  2  herein further comprising a desired artistic design  50 . In the embodiments shown, the artistic design takes advantage of the location and elements of the mask, for example, depicting teeth (either a complete set or a partial set), where the mouth of the user would be, putting an exhalation vent  16  where the nose of a user would be, etc. The design can also comprise, for example as shown in  FIGS. 11 and 12 , a skull as in  FIG. 12  or a skull and crossbones as in  FIG. 11 , and may or may not comprise an exhalation element  16  where the black nose of the skull would be, thereby hiding the exhalation element if desired. The configuration of the artistic design  50  can be adapted to the intended environment for the dust mask  2 . For example, in surgical situations or situations involving children where medical masks should be worn, a smile may help to place child patients at ease in an otherwise uncomfortable setting. The artistic designs depicted herein are merely exemplary; any desired artistic design can be implemented on the mask, including designs that do not have anything to do with the human face. Further, in certain embodiments of this aspect of the dust masks herein, the designs can be applied to dust masks that do not cover the ears. 
         [0046]    Turning to a further discussion of the methods, devices, kits, etc., herein, the mask is typically substantially continuous from ear to ear and can be a simple unitary design (i.e., the mask is not only continuous from ear to ear but at least one ply of the layers of material making up the mask extends from ear to ear without a break). The masks typically comprise multiple layers of protective material plus one or more straps, resilient ear “hooks” or other retaining devices to hold the mask in place. The mask can also comprise, if desired, an exhalation vent and rigidity elements such as a nose bridge. The masks cover the mouth, nose and ears, protecting the user&#39;s hearing and keeping the ears clean without restricting the hearing ability (unless sound protection is also desired, in which case sound reducing materials and/or configurations can be provided). This mask can be made out of the same materials that other lightweight masks such as dust masks, surgical masks, etc., are made from, and are typically made of disposable materials. Also, the masks can be made of other materials such as activated carbon for use with different chemicals and particles. 
         [0047]    The masks are typically designed to be easily put on and disposable and cost-effective, both to the manufacturer and the consumer. The masks are also typically very comfortable to wear. The straps need not go over (touching) the ear causing discomfort of the ears. The mask herein can be made in whatever materials are useful to keep certain unwanted elements out of a wearer&#39;s air passages, nose, mouth and lungs, or at least reduce the amount of such elements out of the wearer&#39;s air passages, etc. Also, the masks can protect the ears from the sun and may reduce ear infections and hearing loss. 
         [0048]    Accordingly, in certain embodiments the devices, systems, methods, etc., discussed herein include masks configured to protect the ears, nose and mouth of a wearer. The masks can be suitably applied for any desired use such as dust protection, for example as found in an auto body shop, protection from hazardous chemicals, for example as found in the manufacture of fiberglass products and certain plastics, and in medical situations, or otherwise as desired. Some exemplary air-borne particulates for which the mask can provide protection include auto paint, asbestos (e.g., dust, fibers, particles), hazardous chemicals, pollen or fiberglass dust, blood splatter, and infectious organisms. 
         [0049]    The specific materials used to make the mask can be selected from any desired set of materials appropriate for the given use. For example, where blood splatter may be of particular concern, then materials having pores small enough to prevent the transmission of blood from the outside to the user would be preferred. In situations where simple dust protection is the primary concern, then larger pores in the material can be used such that respiration is easier, and the need for an exhalation vent or other venting is reduced. The mask can be made of a single layer or multiple layers of a given material, such as a cloth, plastic, paper product, or other material as desired. Typically, the material comprising the bulk of the mask is itself porous, but if desired, the ability to inhale and exhale can be provided through one or more inhalation/exhalation vents (typically identified as an “exhalation vent” in the figures herewith). 
         [0050]    Typically, the contours of the mask on the lower side of the mask are designed to run from behind the ears, along the jaw line of the user then to and/or under the chin, and along the upper line of the mask the edge of the mask typically runs from the ears, along the cheeks and then over the bridge of the nose. Typically, the mask is configured to cover both ears, the nose and the mouth, but in certain embodiments, for example where breathing must be conducted through a specialized oxygen source or respirator or the like, the mask may be configured to cover only the nose and the ears, or, conversely, the ears and mouth but not the nose. The mask does not include eye protection. However, if desired, the mask can advantageously be used in combination with separate eye protection, for example clear plastic eyewear such as used in operating rooms, welder&#39;s masks, or other eye protection as desired. In certain embodiments, the configuration of the upper edge of the mask near the eyes can be specifically conformed to match the lower margin of particular eye protection that the user will be wearing. 
         [0051]    As noted previously, the construction of the mask is typically performed such that the mask is a substantially continuous mask going from one ear, over the nose and mouth, and on to cover the other ear. The mask may be held in place by any desired means, for example via rubber or elastic band(s) extending from one earpiece to the other, from hook-and-loop connector fabric (e.g., VELCRO®) strap(s) extending from one earpiece and the other, or by resilient elements configured to hook behind the user&#39;s ears and to hold the mask in place via mechanical interaction with the ears. The mask may contain one or more additional resilient elements, for example nosepieces, chin pieces, or ribbing or struts, and/or softening elements such as foam under the nosepiece, that can be configured to cause the masks to conform very closely to the user at desired points (for example, along the cheeks or jaw line), or to be held away from the user. Space between the mask and user can be advantageous, for example, around the mouth and nose, to provide a space between the user&#39;s mouth and nose as compared to the mask, and/or around the ears, for example to provide additional comfort so that contact of the ears with the mask is reduced, or to provide space to provide for additional materials such as sound deadening materials between the outer wall of the mask and the user&#39;s ears, or even large enough accommodate additional, separate devices such as ear muffs. 
         [0052]    If desired, the mask can advantageously comprise one or more artistic designs, for example a skull and bones, a smile, or any other design as may be desired. In this specific embodiment, the systems, devices, methods, etc., herein can include lightweight dust masks and the like such as used by carpenters or car painters, which may or may not have the additional ear protection. 
         [0053]    In some embodiments, the mask is provided as a single unitary piece of material that extends from one ear to the other, although if desired the mask can be made in pieces that are attached to each other; in others the mask. The mask is lightweight and should contain few elements where possible, both to reduce cost and to keep the weight down and therefore the comfort for the user up. Thus, the mask should fit snugly to the face, neck and ear region of the user substantially throughout the entirety of the mask. As desired, the mask can also include a liner around the edge formed for strength and/or improved fit relative to the user. 
         [0054]    In certain embodiments, the straps holding the mask to the user&#39;s head are configured such that they comprise at least 2 straps, both departing the mask from or about the upper ear area. A first strap goes from the upper ear to substantially behind the head to the upper contour of the mask above the other ear, while a second retaining strap departs from substantially the same region and travels over the head of the user. If desired, one or both of the straps, typically the strap that travels behind the head, can be attached along a substantial distance along the upper contour (or even the ultimate upper edge) of the mask, thereby providing a substantially continuous retaining and holding force to the mask and reducing the effect of a possible “pinch-point” where the strap departs the mask from a single, small departure spot. 
         [0055]    In certain embodiments, this strap configuration can be used in masks without ear protection, provided the lateral edge of the mask is sufficiently far back on the face to provide adequate purchase for the straps to be effective for the user. 
         [0056]    The straps can be made in any desired fashion, for example (1), hook-and-fabric (e.g., VELCRO®) ends, tie cords (2), with a rubber circle or other “handle” on the back of the nylon strip for grip (3), thicker VELCRO® straps (4), a pull-type strap that tightens up to fit. 
         [0057]    The scope of the present devices, systems and methods, etc., includes both means plus function and step plus function concepts. However, the claims are not to be interpreted as indicating a “means plus function” relationship unless the word “means” is specifically recited in a claim, and are to be interpreted as indicating a “means plus function” relationship where the word “means” is specifically recited in a claim. Similarly, the claims are not to be interpreted as indicating a “step plus function” relationship unless the word “step” is specifically recited in a claim, and are to be interpreted as indicating a “step plus function” relationship where the word “step” is specifically recited in a claim. 
         [0058]    From the foregoing, it will be appreciated that, although specific embodiments have been discussed herein for purposes of illustration, various modifications may be made without deviating from the spirit and scope of the discussion herein. Accordingly, the systems and methods, etc., include such modifications as well as all permutations and combinations of the subject matter set forth herein and are not limited except as by the appended claims or other claim having adequate support in the discussion herein.
