## Abstract

A face mask is a face shield and head strap comprising two layers of plastic having a plurality of blue LED lights which are disposed about each of four face shield sides. The face mask also has a power source, power switch and plurality of air vents. When activated the plurality of blue LED lights act a sanitizer.

## Claims

### Claim 1

A face shield, comprising:
a dual layer plastic plate having a top, a bottom, a pair of sides, a lower corner, a perimeter, the dual layer plastic plate serving as a protective element of the face shield and the dual layer plastic plate is capable of being pivoted upward along a rotational travel path;
a foam rubber cushion disposed along an upper edge of the dual layer plastic plate to allow for properly positioning the face shield when worn;
a pair of pivoting means capable of rotating the dual layer plastic plate upwards with respect to the foam rubber cushion;
a Nylon strap adapted to secure the face shield on a user's head;
a battery enclosure disposed on top of the foam rubber cushion to provide a battery that provides a plurality of electrical power to the face shield;
a sanitizing light source disposed on the top, the bottom and the pair of sides of the dual layer plastic plate;
a power switch located on the lower corner of the dual layer plastic plate to allow for control of the sanitizing light source;
a plurality of ventilation openings disposed around the perimeter of the dual layer plastic plate; and
a wiring harness exiting the battery enclosure, the wiring harness includes a loop to provide adequate slack to allow the dual layer plastic plate to be raised and lowered along the rotational travel path without interference.

### Claim 2 (depends on 1)

The face shield, according to claim 1, wherein the dual layer plastic plate is capable of being rotated to perform one or more actions without interference from the dual layer plastic plate, but without totally removing the face shield via manipulation of the Nylon strap and a fastener.

### Claim 3 (depends on 1)

The face shield, according to claim 1, wherein a plurality of ambient air is capable of entering along the pair of sides and the bottom of the dual layer plastic plate.

### Claim 4 (depends on 3)

The face shield, according to claim 3, wherein the plurality of ambient air is adapted to pass by the sanitizing light sources before entering the user's nose.

### Claim 5 (depends on 3)

The face shield, according to claim 3, wherein the plurality of ambient air is capable of killing one or more germs, bacteria, viruses or other contagions before they are ingested via a user.

### Claim 6 (depends on 4)

The face shield, according to claim 4, wherein any contagion expelled by the user is capable of being killed via the sanitizing light source as they exit the dual layer plastic plate.

### Claim 7 (depends on 3)

The face shield, according to claim 3, wherein the pair of pivoting means is a rivet.

### Claim 8 (depends on 1)

The face shield, according to claim 1, wherein the Nylon strap is secured in place via a fastener.

### Claim 9 (depends on 8)

The face shield, according to claim 8, wherein the fastener is a hook and loop fastener.

### Claim 10 (depends on 8)

The face shield, according to claim 8, wherein the fastener is adapted to size the Nylon strap to properly fit a plurality of head sizes from children to adults.

### Claim 11 (depends on 1)

The face shield, according to claim 1, wherein the battery enclosure includes a box bottom and a box top connected by a hinge and secured by a hasp.

### Claim 12 (depends on 1)

The face shield, according to claim 1, wherein the battery enclosure contains a plurality of replaceable batteries.

### Claim 13 (depends on 1)

The face shield, according to claim 1, wherein the battery enclosure is disposed on top of the foam rubber cushion where it is secured via an adhesive.

### Claim 14 (depends on 13)

The face shield, according to claim 13, wherein the foam rubber cushion is secured to the Nylon strap via the adhesive.

### Claim 15 (depends on 1)

The face shield, according to claim 1, wherein the sanitizing light source is capable of killing one or more germs, one or more bacteria, and one or more viruses before they are breathed in.

### Claim 16 (depends on 15)

The face shield, according to claim 15, wherein the sanitizing light source is capable of killing the one or more germs, the one or more bacteria, and the one or more viruses that are exhaled to allow for protection of others.

### Claim 17 (depends on 1)
