| Abstract: |
A protective facial mask (10) covering the oral and nasal cavities. It slips over the user's head and comprises a single generally cylindrical, generally tubular, piece of an expandable impervious material (12) open at each end. Two diametrically opposed ear slots (14) and an opening (16) below and extending between the ear slots hold the mask in place and provide for better conformity to the user's head. A filtered breathing cannula (18) on the interior of the mask allows air to enter the nasal cavity only.

+ PROTECTIVE FACIAL MASK
+ Field of the Invention This invention relates to a facial mask and more particularly to a protective facial mask which covers both the nasal and oral cavities.
+ Background of the Invention In the past there have been many attempts to provide protective facial devices for a variety of reasons.
Some facial devices protected both the oral and nasal cavities. There are devices which protected the facial cavities from solids only, allowing liquids and air to enter into the facial cavities. Still other devices prevented solids, liquids and air from entering the nasal or oral cavity altogether.
+ Summary of the Invention The foregoing objects and advantages of the present invention are achieved in the embodiment illustrated herein. The present invention resides in the provision 5of a protective facial mask which is worn below the eyes and covers both the'oral and nasal cavities. The mask slips over the user's head and comprises a single generally cylindrical, generally tubular, piece of an expandable impervious material open at each end. Two diametrically opposed ear slots and an opening below and extending between the ear slots hold the mask in place and provide for better conformity to the user's head. The impervious material is an expandable latex compound which conforms to the contours of the user's head when in place. A breathing cannula on the interior of the mask allows air to enter the nasal cavity only. This method of construction allows air to enter the nasal cavity while preventing solids or liquids from entering either the oral or nasal cavity of the user. The breathing cannula contains filtering means to preclude any foreign matter (i.e. particles) from entering the nasal cavity. A pocket-like extension lies below the cannula over the mouth of the user to facilitate speech and provide greater comfort. The mask can be comfortably worn for an extended period of time since neither breathing, hearing, speech nor sight are impaired.
The mask is of a relatively simple design and can easily be put on and taken off by the user. The mask can also be folded into a compact size for ease and economy of packaging, carrying and storage.
+ Brief Description of the Drawing The present invention will be more readily understandable from a consideration of the accompanying drawing in which: Figure 1 is an isometric view of a protective facial mask of the present invention.
Figure 2 is a side view of the mask of Figure I being Figure 3 is a front view of the mask, taken only the line 3-3 of Figure 2.
+ Detailed Description of the Preferred Embodiment In reference to the drawing, Figure 1 is an isometric view of the protective facial mask 10 of the present invention. The mask 10 slips over a user I s head and covers both the nasal and oral cavities. The mask 10 comprises a single, integral, generaily cylindrical piece of an expandable impervious material 12 open at each end. The impervious material 12 may be semitransparent to reveal the user's face. Two diametrically opposed ear slots 14 hold the generally 0tubular mask 10 in place on a user's head. Also, there is an opening 16 below and extending between the ear slots 14. As Figure 1 further illustrates, a standard adult-size, surgical quality breathing cannula 18 is provided on the interior forward portion of the mask 510. The breathing cannula 18 allows air to enter the nasal cavity only.
Figure 2 shows the mask 10 in place on a user's head.
