Description
FIELD OF THE INVENTION

The present invention is directed to a face shield device that provides protection against virus-containing aerosolized particles when cloth, surgical masks, or full-face shields are impractical to use. In particular, the present invention is directed to a handheld demi-face shield device.


BACKGROUND OF THE INVENTION

The following description is not an admission that any of the information provided herein is prior art or relevant to the present invention, or that any publication specifically or implicitly referenced is prior art. Any publications cited in this description are incorporated by reference herein. Where a definition or use of a term in an incorporated reference is inconsistent or contrary to the definition of that term provided herein, the definition of that term provided herein applies and the definition of that term in the reference does not apply.


During the COVID-19 pandemic, the Centers for Disease Control and Prevention (CDC) issued guidance relating to customers at restaurants, recommending masks be worn by employees and customers as much as possible when not eating or drinking and when social distancing measures are difficult to maintain. Generally, employees keep a mask on at all times, whereas customers unmask once the food and drinks arrive, or “when not actively eating or drinking”. Ultimately, this places the employees who interact with unmasked individuals, as well as other close-by restaurant guests and passers-by, at a greater risk of exposure to the virus. Oftentimes, it can take several seconds for a person to resecure his or her mask and may be impractical by the time a person approaches the table. In another scenario, the customer grabs the mask by the center and holds it in place over his or her nose and mouth with his or her hand. This option is unhygienic and may still result in placing the other person at risk of exposure to the virus. Lastly, speech may be muffled while the customer is wearing his or her mask making it difficult for the others to hear. Sound is further muffled when the table is outside and the voice is competing with the restaurant's music, other conversations close by, and traffic.


For the forgoing reasons, and for other scenarios where a mask is impractical, a need exists for a device that is easy to use, and can be rapidly and easily attached and removed from a user's face.


SUMMARY OF THE INVENTION
