The present invention relates generally to face masks. More particularly, the present invention relates to a face mask having modular features.
Many occupational and recreational activities expose individuals to cold weather conditions varying from mild to extreme. Face masks have been developed with the intention to keep a wearer's face protected from adverse cold weather conditions including rain, snow, wind or the like.
While different types of face mask have been proposed for cold weather protection, such face masks have their limitations and can always be improved.
Accordingly, there is a need for an improved face mask for cold weather protection. There is also a need for a face mask having modular features. There is a further need for a face mask that is a waterproof/water resistant. There is an additional need for a face mask made from breathable material. There is a still further need for a face mask made from a material that possesses wicking and anti-microbial properties. There is a need for a face mask that is odor-free. There is an additional need for a face mask that is easier to manufacture, assemble, adjust, and maintain. The present invention satisfies these needs and provides other related advantages.
A face mask described herein provides for cold weather protection. A face mask described herein includes modular features. A face mask described herein is waterproof/water resistant. A face mask described herein is made from breathable material. A face mask described herein is made from a material that possesses wicking and anti-microbial properties. A face mask described herein is odor-free. A face mask described herein is easier to manufacture, assemble, adjust, and maintain.
In one embodiment, a mask for protecting a head with a face having a nose, mouth, and chin, includes a mask module formed of a material. The mask module includes an exterior surface and an interior surface. The mask module is sized and shaped to cover a portion of the face.
The mask module further includes an adjustable upper portion, a middle portion, and a lower portion. The upper portion conforms to at least a portion of the nose. The middle portion includes a multi-layer mouthpiece and a plurality of pleats disposed on opposite sides of the mask module. The pleats provide an accordion-effect in the material of the mask module that defines a space between the interior surface of the mask module and at least the mouth when the mask is worn over the face.
A head module engages the mask module. The head module is configured to engage at least a portion of a head.

In
The mask module 30 and any particular head module 110, 210, 310, 410, 510, 610 are made as separate components and then subsequently integrally connected together. The mask module 30 may be fixedly connected to the head module 110, 210, 310, 410, 510, 610 by, for example, sewing the mask module 30 and the head module 110, 210, 310, 410, 510, 610 together. The mask 30 and head 110, 210, 310, 410, 510, 610 modules may be sewn together using flatseam construction to minimize bulky seams between the mask 30 and head 110, 210, 310, 410, 510, 610 modules. The flatseam construction eliminates multiple layers at the seams between the mask 30 and head 110, 210, 310, 410, 510, 610 modules in order to provide the user with a more comfortable, non-irritable fit.
Alternatively, the mask module 30 may be fixedly connected to the head module 110, 210, 310, 410, 510, 610 by chemicals, such as glues or adhesives. In another alternative, the mask module 30 may be removably connected to the head module 110, 210, 310, 410, 510, 610 by mechanical fasteners (e.g., hook and loop fasteners (e.g., VELCRO fasteners), zippers, pins, clips, latches, straps, hook and eye fasteners, toggle fasteners, snaps (male and female), buttons and button holes, straps and buckles, any type of male/female engaging fasteners, or the like), magnetic fasteners or the like. When the mask module 30 is removably connectable to the head module 110, 210, 310, 410, 510, 610, the mask module 30 can be part of a kit comprising a single mask module 30 and one or more head modules 110, 210, 310, 410, 510, 610 so that a user may switch out and use whichever type of head module 110, 210, 310, 410, 510, 610 the user desires to use at that time, depending on the user's mood, weather conditions, other headgear the user would like to wear, and the like. In the alternative, the mask module 30 may be unitarily formed as a single piece construction with the head module 110, 210, 310, 410, 510, 610.

The mask module 30 includes an adjustable upper portion 36, a middle portion 38, and a lower portion 40. The middle portion 38 includes a multi-layer mouthpiece module or mouthpiece 42 generally aligned with a user's mouth. The mask module 30 also includes a plurality of pleats 44 in the fabric of the mask module 30. The pleats 44 are formed by stitching together lateral folds in portions of the material of the mask module 30 towards the sides of the mask module 30. The pleats 44 are disposed on opposite sides of the mask module 30. The pleats 44 may be located mostly in the middle portion 38 but pleats 44 may be also disposed in the middle to lower part of the upper portion 36 as well as in the upper to middle part of the lower portion 40. The pleats 44 provide a three-dimensional shape to the user's mouth/nose/chin area as this allows the user to have coverage from the bridge of the user's nose to under the user's chin for fit and comfort. The pleats 44 encapsulate the area using an accordion-effect in the material of the mask module 30 created by the pleats 44. The accordion-effect in the material defines a vestibule or space 46 between the interior surface 34 of the mask module 30 and at least the user's mouth when the mask 100, 200, 300, 400, 500, 600 is worn over the user's face. The air within the space 46 and the user's mouth/nose/chin area is generally warmer than air external to the mask module 30, and the space 46 defined by the pleats 44 allows for free movement of the user's mouth and chin so the mask does not substantially move due to the opening and closing motion of the user's mouth while speaking, and maintaining the mask module 30 substantially in place on the user's face. The size and location of the pleats 44 may produce folds 45 in the material of the mask module 30.
The mask module 30 and the head module 110, 210, 310, 410, 510, 610 may be made from various materials. All face masks 100, 200, 300, 400, 500, 600 are designed with protection and warmth as the priority. However, the materials used depend on the mask 100, 200, 300, 400, 500, 600 being used in cold and extreme elements/conditions or in less extreme conditions. Regardless of the external environmental conditions, the fabrics used in the mask module 30 have moisture movement properties that move the moisture away from the user's head and neck to the outer layer of fabric so the moisture can be dispersed/evaporated. At least a portion of the mask module 30 is made of the same material as at least a portion of the head module 110, 210, 310, 410, 510, 610. Alternatively, at least a portion of the mask module 30 is made of a material different from that of at least a portion of the head module 110, 210, 310, 410, 510, 610.
In cold and extreme elements/conditions, an embodiment of the mask module 30 can be made from a material that comprises a waterproof/breathable fabric having wicking and anti-microbial properties. For example, the material can comprise a 100% polyester, three-layer fabric that includes a waterproof/breathable middle membrane (i.e., moisture vapor moves through it). The outer layer of the material, comprising the exterior surface 32 of the mask module 30, can have a smooth knit face with a durable water repellent finish that repels moisture and decreases dry times. The durable water repellent fabric finish keeps the outer fabric of the mask module 30 from becoming saturated with moisture. The durable water repellent fabric finish keeps moisture/snow off the outer (face) fabric so the moisture/snow does not accumulate. In general, it is beneficial to keep the outer fabric of the mask module 30 dry. The middle membrane allows the face mask 100, 200, 300, 400, 500, 600 to breathe while preventing moisture from contacting the user's skin. The inner layer of the material, disposed on the interior surface 34 of the mask module 30, can have a fleeced surface for softness and comfort. The fleeced surface can prevent the user's skin from becoming irritated by movement of the mask 100, 200, 300, 400, 500, 600.
In less extreme (but still cold) conditions, an embodiment of the mask module 30 can be made from a material that comprises an insulating/breathable fabric having wicking and anti-microbial properties, and has a lighter weight construction than the material used for cold and extreme conditions. For example, the material can comprise 89% polyester/11% spandex fabric having a single layer of knitted yarns with a smooth face and a fleeced back. The outer surface of the material, comprising the exterior surface 32 of the mask module 30, includes a smooth knit face with a hydrophobic treatment to repel or push away moisture and decreases dry times. In general, it is beneficial to keep the outer fabric of the mask module 30 dry. The inner surface of the material, comprising the interior surface 34 of the mask module 30, can have a fleeced surface for softness and comfort. The fleeced surface can prevent the user's skin from becoming irritated by movement of the mask 100, 200, 300, 400, 500, 600. Mask modules 30, regardless of the harshness of external weather conditions, can include materials that include moisture management yarns, and antimicrobial treatment (silver-based or the like) for odor-control.
The mouthpiece 42 comprises an outer material layer 48, a middle spacer layer 50, and an inner material layer 52. The mouthpiece 42 prevents direct ingress of incoming air, with the outer material layer 48 deflecting and diffusing incoming air. The middle spacer layer 50 traps air for added thermal benefit, providing an air trap that warms air coming into the mask module 30 from the external environment. In cold and extreme elements/conditions, the mouthpiece 42 can be made from a 100% polyester, 3D spacer fabric with an open mesh material outer face layer 48, a spacer middle lawyer 50, and a knitted material back layer 52. The fabric can be made of yarn having various properties, including antimicrobial (e.g., silver technology for antimicrobial management (e.g., A.M.Y.® antimicrobial yarn; Huntsman Pure by HeiQ)) and moisture management properties (e.g., Sorbtek® moisture management yarn). For example, when manufacturing a yarn, when the polymer is extruded, a powder (additive) having anti-microbial properties can be added so the anti-microbial function is inherent in the yarn. A mask module 30 and a head module 110, 210, 310, 410, 510, 610 incorporating an antimicrobial textile effect makes it possible to keep the face mask 100, 200, 300, 400, 500, 600 odor-free (or at least reduced odor) by inhibiting the growth of odor-causing bacteria. In another example, moisture management can be achieved by the sizes and shapes of yarns used in the mesh fabric materials. The weight of the mesh material of the outer face layer 48 can be approximately 8.2 oz/yd2. In less extreme conditions, the mouthpiece 42 can have a similar construction but the outer face layer 48 uses a lighter weight of mesh fabric material (e.g., approximately 4.5 oz/yd2). Regardless of the external environmental conditions, the mesh fabrics used in the mouthpieces 42 work with a push-pull knit pattern function that pushes away and pulls toward (i.e., the layer or side of the fabric against the face will push and the side of the fabric or layer toward the outside will pull it) in order to expedite moisture transfer as well as enable exceptional airflow for optimal breathability.
The mouthpiece 42 is permanently connected to the mask module 30 (e.g., sewn together using flatseam construction), and provides breathing/ventilation by “mixing the air” or “circulating” the incoming fresh air entering the mask module 30 from the external environment. Alternatively, the mouthpiece 42 may be removably connected to the mask module 30 by mechanical fasteners (e.g., hook and loop fasteners (e.g., VELCRO fasteners), zippers, pins, clips, latches, straps, hook and eye fasteners, toggle fasteners, snaps (male and female), buttons and button holes, straps and buckles, any type of male/female engaging fasteners, or the like), magnetic fasteners or the like. Removably connecting the mouthpiece 42 to the mask module 30 allows the user to switch between different types of mouthpiece (e.g., extreme condition mouthpiece, less extreme condition mouthpiece) or wear the mask module 30 without the mouthpiece 42. The construction of the mouthpiece 42 prevents a user from directly breathing the outside cold air directly into the user's mouth, throat, lungs, and bronchi. By deflecting and diffusing incoming fresh, external air and circulating that fresh air as comes into the mask module 30, the mouthpiece 42 prevents direct cold, harsh wintery air from irritating the user's mouth, throat, and lungs, and subsequent irritation and damage to the user's bronchi. The incoming air is circulated and/or broken up by the mouthpiece 42 as the air enters the mask module 30 on inhalation, with the mouthpiece 42 providing comfort and protection to the user.
The upper portion 36 of the mask module 30 is conformable to at least a portion of the user's nose. The upper portion includes a flexible band 54 disposed within a pocket 56 formed at the upper edge of the upper portion 36. Alternatively, the band 54 can be disposed between layers of the material of the mask module 30. The band 54 can be positioned between mesh and elastic layers for padding (comfort) and to protect the band 54 from coming through the fabric. The band 54 is pliable and conformable to at least a portion of the user's nose. The band 54 provides the upper portion 36 with a flexible nose bridge portion. The band 54 can be made of various flexible, pliable materials that retain the shape the material is bent into including, without limitation, a soft metal, an aluminum alloy, a copper alloy, sheet metal, a silver alloy, composite materials, titanium, and the like. The band 54 can also come in various forms including, without limitation, a thin elongated bar, a thin elongated rod, or any thin elongated circular or polygonal shape, and the like. It is preferred that the band 54 has a flat surface on the side facing the user's face in order to avoid any unnecessary pressure on the user's face. Within the pocket 56, the band 54 extends along the upper portion 36 across the face of the user. In this manner, the band 54 not only extends across and rests upon the upper bridge of the user's nose, but also extends and rests upon the upper cheekbones of the user, thereby disbursing the pressure of the entire mask 100, 200, 300, 400, 500, 600 onto a broader surface of the user's face. This dispersion of pressure is unique in that it adjusts easily to the contour of the user's face on any nose bridge and distance between higher facial cheekbones (i.e., under the user's eyes). The band 54 disperses pressure to the user's cheekbones, eliminates any discomfort, and allows the upper portion 36 of the mask module 30 to be contoured to the user's unique face. With the ability to position and shape the band 54, the shape of the upper portion 36 can be adjusted to increase/decrease contact between the mask module 30 and the user's face, thereby adjusting pressure of the mask module 30 on the user's face. Due to the flexibility of the band 54, the shape of the band 54 and generally conforms to contours of the user's face over which the band 54 is disposed. Again, this results in the weight of the mask 100, 200, 300, 400, 500, 600 being generally dispersed on the user's face generally along the length of the band 54. Ends of the band 54 extend in generally opposite directions, away from the user's nose and across the upper cheeks of the user's face. The length of the band 54 depends on the weight of the mask module 30 itself, and the need to disperse pressure of the mask module 30 on the user's face. For example, the mask module 30 for cold and extreme elements/conditions is heavier than the mask module 30 for less extreme conditions. Thus, the length of band 54 for the mask module 30 for cold and extreme elements/conditions is generally longer than the length of the band 54 required the mask module 30 for less extreme conditions. The band 54 for less extreme conditions may have a preferred approximate length that is about the length required to cover the bridge and at least a portion of the sides of the user's nose down to the user's cheek (the length of the band 54 may vary between the length required to cover the bridge of the user's nose to the approximately full width of the mask module 30 at the top-most part of the upper portion 36). The band 54 for cold and extreme conditions may have a preferred approximate length that is about the length of the upper portion 36 of the mask module 30 itself (i.e., just slightly less than the approximately full width of the mask module 30 at the top-most part of the upper portion 36 so that the band 54 remains contained within the pocket 56). The band 54 for cold and extreme conditions and the band 54 for less extreme conditions may vary in relative length, as described above.
The shape of the upper portion 36 against the user's face can be adjusted to define at least one passage for air to move in or out of the mask. That is, the upper portion 36 of the mask module 30 can be shaped to create small breath holes/vent holes for the passage of air between the interior and exterior of the mask module 30. Thus, the nature of the band 54 also allows the user the ability to not only adjust the pressure points of the upper portion 36 of the mask module 30 on the user's face, but also to regulate the amount of additional air that can be allowed in or out of the mask module 30. Adjusting the shape of the upper portion 36 also provides the user with the ability to regulate the temperature within the mask module 30, as well as regulate the volume of air that can move in and/or out of the mask module 30. By providing the user with the ability to contour and re-configure the shape of the upper portion 36, the user can individually regulate temperature within the mask, pressure of the mask on the user's face, and air volume moving in and/or out of the mask module 30.

The left and right portions 614, 616 are wrapped around the user's head. Fasteners 618 disposed on the distal ends of the left and right portions 614, 616 matingly engage and hold the bandana mask 600 snugly on the user's head. The left and right portions 614, 616 cover at least a portion of the user's ears (i.e., depending on the size of the individual user's ears), and hold the mask module 30 snugly to the user's face with the underside of the user's chin and jaw snugly contained by the mask module 30. The fasteners 618 may come in a variety of forms including, without limitation, mechanical fasteners (e.g., hook and loop fasteners (e.g., VELCRO fasteners), zippers, pins, clips, latches, straps, hook and eye fasteners, toggle fasteners, snaps (male and female), buttons and button holes, straps and buckles, any type of male/female engaging fasteners, or the like), magnetic fasteners or the like. In the alternative, the left and right portions 614, 616 are permanently connected (e.g., sewn together using flatseam construction, a single unitary piece of material, or the like) and the material of the left and right portions 614, 616 is resiliently expandable, stretchable to fit around the user's head and secure the bandana mask 600 in position.
The masks 100, 200, 300, 400, 500, 600 described above can be used in combination with goggles worn by a user to cover the user's eyes. Goggles are typically held over the user's face by an elastic, flexible, length-adjustable strap attached to the goggles. The strap fits around the user's head and positions the goggles over the user's eyes. Goggles can become fogged up when a user's warm, moist, exhaled breath (containing water vapor) rises upwards from the user's mouth, comes into contact with the external environment, which in turn causes goggles worn by the user to fog up when the rising water vapor comes into contact with the goggles. Thus, when a user wears goggles while also wearing a mask 100, 200, 300, 400, 500, 600, the construction of the masks 100, 200, 300, 400, 500, 600 seals off the user's exhaled breath from the external environment and thereby prevents the user's exhaled breath from fogging up the lenses on the user's goggle. The upper portion 36 of the mask module 30 conforms to contours of the user's face, forming a seal between the interior space 46 of the mask module 30 and the external environment. The seal between the upper portion 36 and the external environment prevents goggles worn over the user's face from fogging up as exhaled, warm moist breath is prevented, or at least mostly prevented, from exiting the mask module 30 along the upper portion 36. For example, the flexible band 54 disposed in the upper portion 36 of the mask module 30 allows the upper portion 36 to fit to the face and to the inside of the goggle's frame, thereby preventing the goggles from fogging up.
In an alternative, any one or more of the face masks 100, 200, 300, 400, 500, 600 can also be integrated into a pullover garment, a dickie, scarf, neck warmer or multiple types of hats as a drop down liner. Additionally, any one or more of the face masks 100, 200, 300, 400, 500, 600 can also be integrated into other wearable garments.
Although the present invention has been discussed above in connection with use in outdoor cold weather environments, the present invention is not limited to that environment and may also be used in natural and man-made cold environments such as natural caves, cold-storage facilities, refrigerated containers, walk-in freezers, or the like.
In the alternative, the present invention may also be adapted for non-cold related uses. For example, in alternative embodiments, the mask module 30 can be adapted for use in environments where the air is laden with dust and/or pollen. For example, the face masks 100, 200, 300, 400, 500, 600 can be adapted for use in dust/sand storms, windy days with significant and high levels of pollen, and the like. In the foregoing situations, the mouthpiece 42 could be adjusted to provide one or more of the layers with increased air filtration properties or by adding an additional filter layer to the mouthpiece 42. Likewise, the mask module 30 could be adapted to use a lighter weight material for use in a warmer climate/environment. In a further alternative, the mask module 30 can be adapted for use in polluted environments where, for example, the mouthpiece 42 is adjusted to provide one or more of the layers with increased filtration properties or by adding an additional filter layer to the mouthpiece 42.
In a further alternative, the materials used in the face masks 100, 200, 300, 400, 500, 600 could be treated with various substances (e.g., aromatic, medicinal, therapeutic, or the like) or constructed with additives that provide aromatic, medicinal and/or therapeutic effects on the person wearing the face mask 100, 200, 300, 400, 500, 600.
In addition, the claimed invention is not limited in size and may be constructed in versions suitable for adults and non-adults in which the same or similar principles of cold weather protection as described above would apply. Likewise, the size and shapes of the face masks and their components described above are not to be construed as drawn to scale in the figures referred to herein, and that the sizes of the face masks may be adjusted in conformance with industry standard sizes for adult and non-adult humans. Furthermore, the figures (and various components shown therein) of the specification are not to be construed as drawn to scale.
Throughout this specification the word “comprise”, or variations such as “comprises” or “comprising”, will be understood to imply the inclusion of a stated element, integer or step, or group of elements, integers or steps, but not the exclusion of any other element, integer or step, or group of elements, integers or steps.
The use of the expression “at least” or “at least one” suggests the use of one or more elements or ingredients or quantities, as the use may be in the embodiment of the disclosure to achieve one or more of the desired objects or results.
The numerical values mentioned for the various physical parameters, dimensions or quantities are only approximations and it is envisaged that the values higher/lower than the numerical values assigned to the parameters, dimensions or quantities fall within the scope of the disclosure, unless there is a statement in the specification specific to the contrary.
The terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. As used herein, the singular forms “a”, “an” and “the” may be intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises,” “comprising,” “including,” and “having,” are inclusive and therefore specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
