DETAILED DESCRIPTION

[0033] Various terms used herein are intended to have particular meanings. Some of these terms are defined below for the purpose of clarity. The definitions given below are meant to cover all forms of the words being defined (e.g., singular, plural, present tense, past tense). If the definition of any term below diverges from the commonly understood and/or dictionary definition of such term, the definitions below control.

[0034] Embodiments of face masks (or “facemasks”) disclosed herein, such as a facemask 10 as shown in FIG. 1, may include a facemask portion 12 that is formed of fabrics and materials which can either be molded to retain a specific shape, or simply remain in a flexible and foldable state and worn upon the face of a person (or “user”) to at a minimum cover the user's mouth and nose; and some facemasks can be designed without, or to, provide protection to the user from airborne or liquid-based hazards by the utilization of some filtration method of the air coming in through the mask which may be inhaled by the user or exhaled by the user pushing air out through the mask, and can include facemasks equipped with an exhale valve; and utilize different methods or configurations which allow the user to wear the facemask and have it fit their face in a way to maximize the intended benefits, capabilities, purposes, or uses of that facemask.

[0035] Embodiments of the facemask 10 described herein fit upon a user's face to substantially form a seal so air travelling into the facemask is inhaled and to exhaled such that air passes out of the facemask 10 through an intended filtration mechanism. Depending upon the seriousness of the hazard the requirement for the secureness of the seal may be different. Further, depending upon the size of particles to be filtered, the properties and specifications of the filtration mechanism may vary. Filtering sawdust is different than filtering asbestos, which is different than filtering bacteria or viruses. A goal of the facemask is to provide based upon not only the filtration properties of the facemask but the secureness of that fit to maximize those intended benefits.

[0036] The facemask portion 12 includes a pocket 13 located therein for receiving a filter element 15. The pocket 13 may be formed such that the pocket 13 is accessible from an inner side of the facemask portion 12. For example, a slot may be formed on the inner side of the facemask portion 12 such that the pocket 13 is located between an outer surface of the facemask portion and the inner side of the facemask portion 12.

Nose Bridge Device

[0037] Embodiments disclosed herein provide a unique, different, and innovative type of nose bridge device or nose bridge portion 14 which is made of different material, shape, and dimensions which together significantly improves the effectiveness over any other previous nose bridge device on a facemask, creating a more secure and comfortable fit.

[0038] The new nose bridge device 14 may be from about 10 cm to about 20 cm in length and may be approximately 18 cm in length and may be round having a diameter of from about 1.5 mm to 2 mm. The nose bridge portion 14 may be formed of a deformable metal wire, such as an aluminum/tin alloy. One example of a suitable material for the nose bridge portion 14 is armature. Armature is very flexible and can be articulated in almost any fashion. Yet armature has strength and is durable. Armature may be easily malleable so that when affixed to or embedded in a facemask, when the user puts the facemask on, placing it on their face, instead of simply pinching the device at the bridge of the user's nose, the user can instead use their fingers to conform the armature nose bridge device past the area of the nose and to the contours of the user's face.

[0039] The length of the armature nose bridge device may be approximately 18 cm, which may extend substantially across a width of an upper edge of the facemask portion 12, and which is over twice as long as the standard 8 cm length of other facemasks, creates a significant advantage as the extra length allows for fitting of the device to more area of the user's face which results in a more secure and comfortable fit than other facemasks currently available.

[0040] The armature nose bridge device is round rather than being flat. This allows the armature nose bridge device to fit to the contours of a user's face at any angle and is not dependent upon a flat or right-angle to maximize the benefits of the standard nose bridge device on other facemasks. This results in a more secure and comfortable fit than other facemasks currently available.

[0041] While the standard nose bridge device on other facemasks after a relatively short period of time does not maintain a close fit and tends to expand or loose contact with the user's skin, the strength of the armature nose bridge device allows that device to maintain its shape for longer periods of time and because of its length it can obtain and thus maintain contact with the user's skin for a much longer periods of time. The effect created is as if the armature nose bridge device is able to gently grab hold of that portion of the user's face and stay attached. This affect results in less movement of that device which adds to its ability to obtain and maintain a secure fit.

[0042] Other benefits are created by a facemask which is utilizing the armature nose bridge device. Because a more secure and comfortable fit than other facemasks currently available is obtained and maintained, little or no air is escaping from the facemask in that area and this in turn essentially eliminates all fogging of the user's eye or sunglasses. Also, if the armature nose bridge device keeps the facemask in place, then there is less tendency of the user to constantly touch or try to readjust the facemask which prevents cross-contamination from anything which might have accumulated on the facemask and which might be touched.

[0043] The nose bridge portion 14 may be located within a hem 16 of the facemask portion 12. The hem 16 may be located substantially across a width of an upper edge of the facemask portion 12 for securing the nose bridge portion 14 therein.

Elastic Ear Straps

[0044] Embodiments herein provide an effective type of elastic ear strap which significantly lessens the potential for an opening or gap at each side of the facemask and is more efficient and better maximizes the elastic properties of the straps.

[0045] Specifically, embodiments disclosed herein provide a different and innovative elastic ear strap which configures these elastic ear straps so that on each side a single strap is attached to itself forming a separate continuous loop and then embedded in a sleeve configured from the facemask's material at the side of the facemask in such a way that the ear strap will not vertically slip or move within the sleeve resulting in more force at the middle of the mask's side, which “gathers” that portion of the mask, significantly improving the results of any other previous elastic ear strap configuration on a facemask, creating a much more secure fit.

[0046] As shown in FIG. 4, a first ear strap 18 is located along a first side of the facemask portion 12 and a second ear strap 20 is located along a second side of the facemask portion 12. The first ear strap 18 may be secured on the facemask portion 12 through a first channel 22 located along the first side of the facemask portion 12. The second ear strap 20 may be secured on the facemask portion 12 through a second channel 24 located along the second side of the facemask portion 12. The first ear strap 18 may be slidable through the first channel 22 and the second ear strap 20 may be slidable through the second channel 24. The first channel 22 and the second channel 24 may be formed as hems along the side edges of the facemask portion 12. Further, the first channel 22 and the second channel 24 may be located over sides of the nose bridge portion 14 to secure the nose bridge portion 14 on the facemask portion 12.

Detection and Monitoring Technology

[0047] Embodiments of facemask 10 disclosed herein provide a new and innovative way to enhance the capabilities of the facemask by adding a new purpose and use by configuring the facemask's exterior to provide capabilities for detection and/or monitoring capabilities related to such areas as radiation and UVC light.

[0048] Currently on the market are various detection and/or monitoring devices which take the form of essentially a two-dimensional card 26, as shown in FIG. 5. These devices can be of almost any imaginable size including sizes of 2 cm×5-6 cm. Examples of these devices are Radiation “Exposure Cards” or “Dosimeters” or UVC Light Exposure Cards or Dosimeters. It is a compliment of usage to consider that in situations where the need to utilize a facemask with a filtration device exists that circumstances of that situation would also cause a user to be concerned about exposure to substances such as radiation, biological, chemical, or UVC light. At present no facemask of any type is on the market which also accommodates any type of detection or monitoring technology.

[0049] Embodiments of this disclosure accommodate the configuration of the exterior of the facemask to utilize either a narrow pocket 28 to be placed into the facemask via slit in the outer material of the facemask with either additional material for that pocket or not to accommodate a detection and/or monitoring device of the appropriate size; or to have on the exterior of the facemask a method or capability to attach in some manner a detection and/or monitoring device of the appropriate size.

[0050] Of the methods or configurations utilized on existing facemasks to maximize the intended benefits of that facemask, a method or configuration on a facemask is provided which utilizes a nose bridge device made of armature and has the dimensions of 18 cm in length and round at 1.5 mm to 2 mm in diameter, as opposed to the standard nose bridge device of 8 cm in length 0.5 cm wide is flat and made of plastic and very thin wire, to provide a more secure and comfortable facemask fit that better holds the facemask to the user's face and eliminates eye or sunglass fog experienced from facemasks with the standard nose bridge device.

[0051] Of the methods or configurations utilized on existing facemasks to maximize the intended benefits of that facemask, a facemask is provided which utilizes an improved method and configuration of the way elastic straps are utilized on a facemask to hold the facemask to the user's face by having each elastic strap be a separate and closed loop which is embedded in separate sleeves on each side of a facemask that in turn uses tensions to the elastic straps when placed on the user's face to help provide a more secure and comfortable fit.

[0052] Embodiments herein provide a new and innovative way to enhance the capabilities of a facemask by adding a new purpose and use by configuring the exterior of the facemask to utilize either a narrow pocket to be placed into the facemask via slit in the outer material of the facemask with either additional material for that pocket or not to accommodate a detection and/or monitoring device of the approximate size of 2 cm wide by 5 cm to 6 cm long; or to have on the exterior of the facemask a method or capability to attach in some manner a detection and/or monitoring device of the same approximate size.

[0053] The foregoing description of preferred embodiments of the present disclosure has been presented for purposes of illustration and description. The described preferred embodiments are not intended to be exhaustive or to limit the scope of the disclosure to the precise form(s) disclosed. Obvious modifications or variations are possible in light of the above teachings. The embodiments are chosen and described in an effort to provide the best illustrations of the principles of the disclosure and its practical application, and to thereby enable one of ordinary skill in the art to utilize the concepts revealed in the disclosure in various embodiments and with various modifications as are suited to the particular use contemplated. All such modifications and variations are within the scope of the disclosure as determined by the appended claims when interpreted in accordance with the breadth to which they are fairly, legally, and equitably entitled.
