Abstract

A face shield for use with protective headgear can be shipped flat and easily assembled from a kit of parts without the use of tools or adhesives. The face shield protects against disease, aerosols and splatter that may contain pathogens; may include a curved lower perimeter to facilitate head movements, and can be taken on and off easily.

First claim

What is claimed is:

1. A kit for a face shield, comprising:
a transparent face covering of a length sufficient to cover at least a user's eyes and mouth, the transparent face comprising:
a curved perimeter along a bottom edge;
a first plurality of slots located proximate a top edge and a left side outer perimeter;
a second plurality of slots located proximate said top edge and a right side outer perimeter; and,
a first and second set of headband slots; and,

a headband having a plurality of notches sized to mate with said headband slots.

2. The kit of claim 1 , further comprising:
a compression strap sized to fit through said first and said second plurality of slots.

3. The kit of claim 2 , wherein said compression strap comprises elastic.

4. The kit of claim 2 , wherein said compression strap comprises cord.

5. The kit of claim 2 , wherein said compression strap comprises a shoelace.

6. The kit of claim 1 , wherein said transparent face covering comprises a transparent plastic.

7. The kit of claim 6 , wherein said transparent plastic comprises polycarbonate.

8. The kit of claim 1 , wherein said transparent face covering and said headband comprises polyethylene terephthalate glycol.

9. The kit of claim 1 , wherein said transparent face covering and said headband are formed by additive manufacturing.

10. The kit of claim 1 , wherein said transparent face covering and said headband are formed by injection molding.

11. A method for making a face shield, comprising the steps of:
attaching a headband to a transparent sheet of material, wherein said step of attaching further includes the steps of:
inserting a first headband tab between a first slot and a second slot on said transparent sheet;
inserting a second headband tab between a third slot and a fourth slot on said transparent sheet;
engaging a first headband notch with said first and second slot; and,
engaging a second headband notch with said third and fourth slots; and,

attaching a compression strap to said transparent sheet of material.

12. The method of claim 11 , wherein said step of attaching a compression strap further comprises the steps of:
threading a first end of said compression strap through a first plurality of slots located on said transparent material; and,
threading a second end of said compression strap through a second plurality of slots located at a second location on said transparent material.

13. The method of claim 11 , wherein said step of attaching a compression strap further comprises the steps of:
threading a first end of a first compression strap through a first plurality of slots located at a first location on said transparent material; and,
threading a first end of a second compression strap through a second plurality of slots located at a second location on said transparent material.

14. The method of claim 11 , further comprising the step of placing said compression strap around a protective headgear of a user.

15. A face shield comprising:
a transparent face covering of a length sufficient to cover at least a user's eyes and mouth, the transparent face comprising:
a first plurality of compression strap slots located proximate a top edge and a left side outer perimeter;
a second plurality of compression strap slots located proximate said top edge and a right side outer perimeter; and,
a first plurality and a second plurality of headband slots;

a headband having:
a first end threaded through said first plurality of headband slots;
a second end threaded through said second plurality of headband slots;
a first notch located proximate said first end and connected to at least one of said first headband slots; and,
a second notch located proximate said second end and connected to at least one of said second headband slots; and,

a compression strap having threaded through said first and second plurality of compression strap slots.

16. The face shield of claim 15 , wherein said transparent face covering further comprises a curved bottom perimeter.

17. The face shield of claim 15 , wherein said compression strap comprises elastic.

18. The face shield of claim 15 , wherein said compression strap comprises cord.

19. The face shield of claim 15 , wherein said compression strap comprises a shoelace.

20. The face shield of claim 15 , wherein said transparent face covering comprises a transparent plastic.

21. The face shield of claim 20 , wherein said transparent plastic comprises polycarbonate.

22. The face shield of claim 15 , wherein said transparent face covering and said headband comprises polyethylene terephthalate glycol.

23. The face shield of claim 15 , wherein said transparent face covering and said headband are formed by additive manufacturing.

24. The face shield of claim 15 , wherein said transparent face covering and said headband are formed by injection molding.

25. The face shield of claim 15 , wherein said transparent face covering and said headband are formed by laser cutting.

26. The kit of claim 1 , wherein said transparent face covering and said headband are formed by laser cutting.
