DETAILED DESCRIPTION

Reference will now be made in detail to embodiments of protective masks, examples of which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals will be used throughout the drawings to refer to the same or like parts. Various embodiments of protective masks will be described in further detail herein with specific reference to the appended drawings. It us to be understood and within the scope of this disclosure that the masks described herein are operable as face coverings for a multitude of uses and for one or more users in a variety of environments ranging from, and not limited to, general purpose environments, commercial environments, and/or medical environments. Any numerical dimensions described herein are non-limiting examples.

Protective masks used by medical professionals, first responders, and other people to protect those wearing the masks and/or others around the mask wearers against transmission of contagions (further including, but not limited to, and other harmful particulate matter such as bacteria, mold, smoke, and dust) such as a virus transmitted through air particulates are desired by those seeking such protection. For example, a person sneezing or coughing may transmit the contagion to another nearby person, and a protective mask may protect against such a transmission. Such masks may be referred to as personal protective equipment (“PPE”) worn by users to minimize exposure to hazards such as airborne particles that may cause illness. N95 masks are examples of such masks and PPE that act as a particulate-filtering face mask respirator to filter at least 95% of airborne particles.

The protective masks such as those described in embodiments herein protect against such a transmission in a manner that prevents fogging of eyewear of the person wearing the mask, improves breathability of the person through adjustable and sealable features, and/or provides a customizable comfortable fit for the user as the person wearing the protective mask as a breathable filtration device. The protective masks described herein may further be configured to convert from mask design to other fashion accessory design in a non-mask configuration, such as a headband or neck scarf, in a sporty, indoors or outdoors oriented configuration. The protective masks described herein are configured to provide a breathable and reusable face covering providing filtration protection for user's against contagions such as viral and allergen contagions as airborne particles a user wishes to filter out when breathing in oxygen. In embodiments, the covering may be made of a 1900 series filtration material that is allergy and asthma friendly.

Referring back to FIG. 3, in another embodiment, a protective mask 300 includes similar features of the protective mask 200 except with differences noted herein. The protective mask 300 is shown on a person 100 in an environment 250 in a tied configuration. The environment 250 may be, for example, an airport, a mall, a crowded venue, a medical setting such as a hospital, or other environment at which the person 100 is located and which includes a plurality of people.

Referring to FIG. 4, a front cover portion 303 of the protective mask 300 is shown. The front cover portion 303 includes a front nose portion 302, a nosebridge 309 (FIG. 6) disposed in a nose pocket 304, a center vertical axis 310, a top boundary 306, a bottom boundary 308, and side boundaries 316. In embodiments, the nosebridge 309 may include a rectangular bottom and a top portion with an intermediate bump. As a non-limiting example, the top boundary 306 is configured to define a bump portion 320, dip walls 322, upward angled side walls 325 (FIG. 7) including bottom portion 324 and upper portion 326, and downward angled side walls 328. In embodiments, the nose pocket includes the bump portion 320 as a first bump portion along the top boundary 306, and the nosebridge 309 includes a second bump portion 360 (FIG. 7). The first bump portion 320 of the nose pocket is sized and shaped to house the second bump portion 360 of the nosebridge 309.

The dip walls 322 are configured to extend from bottom side ends of the bump portion 320 in opposite directions until ending at second side ends. Each upward angled side wall 325 is configured to extend upwardly at an angle with respect to the center vertical axis 310 and from the respective second end of the dip wall 322 until reaching a top point at an end of upper portion 326. From the top point of each upper portion 326 of each upward angled side wall 325, each downward angled side wall 328 is configured to downwardly extend at an angle with respect to the center vertical axis 310 until reaching an upper side point of the side boundaries 316. From the upper side point, a side boundary wall 330 is configured to extend at an inward tapered angle with respect to the center vertical axis 310 toward a bottom side point of the side boundaries 316. At the bottom side point of the side boundaries 316, a bottom wall 332 is configured to extend inwardly toward the center vertical axis 310 to define a chin boundary portion 318 of the bottom boundary 308.

The protective mask 300 may include a nose pocket in which a nosebridge 309 (FIG. 6) is disposed. The bump portion 320 is a part of the nose pocket and is configured to be disposed around to cover a bump portion of the nosebridge 309. Referring again to FIG. 4, collectively, the bump portion 320 and the dip walls 322 are configured to cover a portion of a nose 102 and nose side portions of the person 100. Further, each upward angled side wall 324 and respective downward angled side wall 328 are configured to define ear portions 314 to cover, as ear coverings, portions of a respective ear 106 of the person 100. In embodiments, when the ear portions 314 cover portions of the ears 106 of the person 100 in a tied configuration, the upward pull of the ear portions 314 on the protective mask 300 is countered by the bump portion 320 such a resulting downward pull on the nose area of the top boundary 306 causes the bump portion 320 to remain seated on a portion of the nose 102 of the person 100 in a sealed and tight fitting configuration. This sealed and tight fitting configuration is due to a light tension exerted by and seating of the bump portion 320 against the nose 102 of the person 100 in reaction to the upward pull of the ear portions 314 on the protective mask 300 in the tied configuration.

The bottom wall 332 further defines a bottom gutter boundary 336. A top gutter boundary 334 and the bottom gutter boundary 336 define a gutter 338 configured to define an aperture between the front cover portion 303 and the rear cover portion 305 (FIG. 6) within which a drawstring 348, 350 (FIG. 5) of tie portions 340 may be disposed (e.g., placed).

Referring to FIG. 5, the gutter 338 is disposed at least along the side boundaries 316 and the chin boundary portion 318 of the bottom boundary 308. A drawstring 348 may be disposed in the gutter 338 of each side boundary 316, and a drawstring 350 may be disposed in the gutter 338 of the chin boundary portion 318. The drawstrings 348, 350 may be configured to be drawn within and along the respective gutter 338 to tighten or loosen a fit of the bottom boundary 308 of the protective mask 300 again the cheek and chin features of face of the person 100.

In embodiments, the protective masks 200, 300 as described herein may include at least one tie portion configured to tie the protective mask to the face of the user (e.g., the person 100) in the tied configuration for an adjustable fit from an open and loose configuration. In embodiments, an elastic slider forward position or elastic slider back position may convert the protective masks 200, 300 from an open and loose configuration to a closed and taut configuration. As a non-limiting example, the protective mask 300 may include a plurality of tie portions 340. The tie portions 340 may include a top tie portion 342, a side tie portion 344, and a bottom tie portion 346 including the drawstrings 348, 350. The tie portions 340 include respective pair of ties of tie portions 342, 344, 346 configured to tie at a meeting point behind the head of a person in a tied configuration (e.g., including, but not limited to, fastening via toggles, neoprene, VELCRO, elastic, and snaps, or any combination thereof) of the protective mask 200. In embodiments, ends of the top tie portion 342 and the side tie portion 344 are fixed against the respective ear portions 314 and side boundaries 316 of the protective mask 300, such as in a sewn configuration. The drawstrings 348, 350 may be drawn along the gutter 338 to loosen or tighten and be clamped in a desired position by a common moveable clamp 352. Thus, in embodiments, the bottom tie portion 346 includes the pair of drawstrings 348, 350 as a first drawstring 348 and a second drawstring 350 coupled via the movable clamp 352. The bottom tie portion 346 may include the first drawstring 348 and the second drawstring 350 disposed in the gutter 338.
