Face Shield For Protecting Face of Wearer

Abstract

The present disclosure provides a face shield including one or more airstream-deflecting protrusions for deflecting airstream away from the wearer so as to avoid bacteria, virus or any other hazardous materials in the airstream from depositing on the head and/or hair of a wearer. The present disclosure further provides a full face shield including a flexible sheet, and the flexible sheet has a top portion comprising two folding structures located adjacent to lateral edges of the flexible sheet respectively for bending the top portion towards a forehead of a wearer. As the top portion of the full face shield is bent towards a forehead of the wearer through the folding structure, the face, forehead and a large portion of the front skull of the wearer can be protected.

What is claimed is: 
     
         1 . A face shield comprising:
 a sheet for protecting a face of a wearer, the sheet comprising one or more airstream-deflecting protrusions, each airstream-deflecting protrusion protruding from the sheet and being located below a top edge of the sheet for deflecting airstream away from the wearer when the airstream directs to the sheet.   
     
     
         2 . The face shield of  claim 1 , wherein the one or more airstream-deflecting protrusions are arranged in a line being in parallel with the top edge. 
     
     
         3 . The face shield of  claim 1 , wherein the each airstream-deflecting protrusion is hollow. 
     
     
         4 . The face shield of  claim 1 , wherein the each airstream-deflecting protrusion is rectangular, cubic, cylindrical, or semi-conical. 
     
     
         5 . The face shield of  claim 1 , wherein the each airstream-deflecting protrusion has a height between 3 mm and 15 mm. 
     
     
         6 . The face shield of  claim 1 , wherein the sheet and the one or more airstream-deflecting protrusions are integrally formed as one piece. 
     
     
         7 . The face shield of  claim 1 , wherein the sheet further comprises one or more head-contacting protrusions, each head-contacting protrusion protruding from the sheet and being located below the top edge for contacting to a head of the wearer. 
     
     
         8 . The face shield of  claim 7 , wherein the one or more head-contacting protrusions are arranged in a line being in parallel with the top edge. 
     
     
         9 . The face shield of  claim 7 , wherein the each airstream-deflecting protrusion and the each head-contacting protrusion are arranged in consecutive sequence in line, the each airstream-deflecting protrusion outwardly protruding from the sheet, the each head-contacting protrusion inwardly protruding from the sheet. 
     
     
         10 . The face shield of  claim 1  further comprising a headband being attachable to the sheet for mounting the face shield on the head of the wearer. 
     
     
         11 . The face shield of  claim 10 , wherein the sheet further comprises a plurality of slots; the headband comprising a narrower portion and a wider portion, the narrower portion having a width being less than a width of each slot to allow the narrower portion to pass through the plurality of slots, the wider portion has a width being greater than the width of each slot such that the wider portion is stopped by an individual slot at a transition between the narrower portion and the wider portion. 
     
     
         12 . The face shield of  claim 10 , wherein the headband comprises a hook fastener and a loop fastener for connecting the headband. 
     
     
         13 . A full face shield comprising:
 a flexible sheet for protecting a face of a wearer, the flexible sheet having a top portion, the top portion comprising two folding structures located adjacent to lateral edges of the flexible sheet respectively for bending the top portion towards a forehead of the wearer, each folding structure comprising a first patch, a second patch, a cutting line and a securing structure, the first patch being located between the lateral edge and the second patch, the cutting line separating the first patch and the second patch, the first patch and the second patch being arranged to be overlapped with each other, the securing structure being used for fastening the overlapped first and second patches together.   
     
     
         14 . The full face shield of  claim 13 , wherein the flexible sheet is bent along a direction of the cutting line, the first patch and the second patch are bent such that the first patch and the second patch are overlapped with each other; and the securing structure fastens the overlapped first and second patches together. 
     
     
         15 . The full face shield of  claim 14 , wherein the securing structure comprises one or more sinking bulbs located within the first patch and one or more bulging bulbs located within the second patch, each sinking bulb protruding from the first patch, each bulging bulb protruding from the second patch, each bulging bulb being arranged to be attached to a respective sinking bulb such that the overlapped first and second patches are fastened together. 
     
     
         16 . The full face shield of  claim 14 , wherein the securing structure comprises one or more sinking bulbs located within the second patch and one or more bulging bulbs located within the second patch and one or more bulging bulbs, each sinking bulb protruding from the first patch, each bulging bulb protruding from the second patch, each bulging bulb being arranged to be attached to a respective sinking bulb such that the overlapped first and second patches are fastened together. 
     
     
         17 . The full face shield of  claim 13 , wherein the securing structure comprises one or more sinking bulbs located within the second patch and one or more bulging bulbs located within the first patch, each sinking bulb protruding from the second patch, each bulging bulb protruding from the first patch, each bulging bulb being arranged to be attached to a respective sinking bulb. 
     
     
         18 . The full face shield of  claim 13 , wherein the flexible sheet further comprises one or more head-contacting protrusions, each head-contacting protrusion protruding from the flexible sheet and being located below the top portion for contacting to a head of the wearer. 
     
     
         19 . The full face shield of  claim 13 , wherein the flexible sheet further comprises one or more airstream-deflecting protrusions, each airstream-deflecting protrusion protruding from the sheet and being located below the top portion for deflecting airstream away from the wearer when the airstream directs to the flexible sheet. 
     
     
         20 . The full face shield of  claim 13  further comprising a headband being connectable to the flexible sheet.
