Abstract
A disposable face shield having an improved attachment mechanism for securing a band to attach the shield to a user's face is disclosed. The disposable face shield includes a flexible transparent member having at least one slit therethrough. The slit edges have points that grab the elastic holding strap at a selected location to make a selected adjustment of the face shield to the user's head. A flexible forehead support member is provided on the upper portion of the transparent member to nestle against a user's forehead.
Description
- This invention relates generally to face shields. More particularly, this invention relates to a disposable face shield having an improved adjustable attachment for a band securing the shield to the user's head.
- It has long been advantageous for individuals working with liquids to wear a protective face shield to prevent those liquids from spattering on the face. For example, face protection in medical procedures to prevent the splattering of blood on the face is recommended. It is also advantageous in medical procedures to use disposable surgical equipment where possible to substantially reduce the risk of infection and the cost of sterilizing the surgical equipment. Additionally, cleaning face shields of deposited chemicals, such as blood, paint, adhesives, dyes, solvents, resins, etc., is time consuming and often ineffective. Thus, disposable face shields have seen a wide application in various industries, e.g. medicine, dentistry, painting, manufacturing, and the like.
- Because of the wide application and use of disposable face shields, the mounting bands or straps which secure the shield to the face must be adjustable to accommodate a variety of different sized faces and heads. Some prior art face shields utilize a fastener or integral member to attach the band or strap to the shield. A prior art face shield as disclosed in U.S. Pat. No. 5,983,390 to Desy makes use of slits with smooth edges, formed in the flexible transparent face shield material itself. A strap having a width greater than the width of the slits is looped through the slits. The straps are threaded in a particular direction through the slits. Pulling on the ends of the strap, so threaded, decreases the amount of strap positioned to hold the shield to a user's head, thus making a secure fit.
- However, such slits, and therefore disposable face shields having those slits, can be improved upon as will be disclosed in the present application.
- A face shield has a flexible transparent portion with a flexible forehead support member, and is held on a user's head by an elastic strap. The elastic strap has pores, and is threaded through at least one slit in the flexible transparent portion. The edges of the slits have points that enter the pores of the strap, and keep the elastic strap at a desired position in the slits, so that the face shield has a desired tightness and remains in position on the wearer.
- Another version of the face shield has a strap without pores. The pointed teeth or edges of the slit press into the surfaces of the strap, since they cannot enter pores.
- In another version, face shields having slits are available without a strap attached.

FIG. 6 is similar toFIG. 4B , but illustrates another embodiment of a disposable face shield. - With respect to
FIG. 1 , thehead 5 of a wearer 6 has adisposable face shield 10 secured by astrap 12. Theface shield 10 has atransparent member 14 and aflexible support member 16 made of foam and havingrelief cuts 18. The foam support member may be of many materials and configurations, as is already known in the art. Thetransparent member 14 may be a variety of flexible materials known in the art, such as for example, polyethylene terephthalate (PET), with a thickness range of 0.20 to 0.24 mm. -
FIGS. 2A and 2B are top views of theface shield 10 while removed, and while being worn. For purposes of describingface shield 10, directions, orientations, and centerlines will be used from the perspective of a wearer. There is aninner area 20, anouter area 22, a right side 24 a left side 26 afront 28 and aback 30. Animaginary centerline 32 divides thetransparent member 14 into aright half 34 and aleft half 36. Aright slit 38 in the right half divides the right half in to a rightforward member 40 and aright end 42. Aleft slit 44 in the left half divides the left half into a leftforward member 46 and aleft end 48. Theright slit 38 is visible inFIG. 1 , but theleft slit 44 is hidden from view. Only one of the two slits is necessary to practice the invention, although having both slits is preferred. In an embodiment without the second slit, thestrap 12 may be secured to thetransparent member 14 in some other manner, that may or may not be adjustable. - The strap has a
right end 50, an opposingleft end 52, aninner surface 54, anouter surface 56, and a width 58 (FIG. 3 ). When installed in thetransparent member 14, theslits right pull 60, aleft pull 62, and awrap section 64 between the right pull and left pull. As illustrated, the left and right pulls have an optional folded over section (not numbered) making thestrap 12 easier for a wearer 6 to grip. Thestrap 12 may be plain as illustrated, or have a different shape. - The arrows in
FIG. 2B indicate how a wearer 6 would use theright pull 60 andleft pull 62 to comfortably tighten theface shield 10 once they have placed it around theirhead 5. As they tighten or loosen theface shield 10, the relative amount ofstrap 12 in thewrap section 64 and theright pull 60 andleft pull 62 changes. This embodiment of thedisposable face shield 10 has twoslits face shield 10 does not shift thetransparent member 14 around the wearer'shead 5. If instead only one slit was in thetransparent member 14 surrounding only one end of thestrap 12, and the other strap end was fixed (or not easily adjustable concurrent with the first strap end), then repositioning oftransparent member 14 after tightening may be necessary. - The
slits strap 12 will be further described with reference toFIGS. 3-5 , that detail theright slit 38. This description applies equally to a second or any other slit, for example the left slit 44.Slit 38 is made by cutting thetransparent member 14 in a zigzag pattern to formforward teeth 66 on aforward edge 68 on theright forward member 40, andrear teeth 70 on arear edge 72 on theright end 42. In this embodiment each of theteeth point 73, although in other embodiments the teeth may not be pointed. The zigzag cut is typically made by a die, and it may be the same die that cuts thetransparent member 14 from a larger expanse of material. The illustrated embodiment is of a zigzag along a straight axis rather than a non-straight axis, although another embodiment may have an axis that is not straight. “Axis” is used herein to mean the general path of travel of a line bisecting the zigzag in its longitudinal direction. The material is cut rather than punched. The term “punched” is used herein to mean a process that results in material being removed and typically discarded. Since no material is removed from thetransparent member 14,edge 68 abutsedge 72. Theteeth FIG. 5B ) may have teeth in which apitch 78 is different than awidth 80. Theslit 38 has awidth 82 andrelief holes 84 at either end. The relief holes 84 are punched out to prevent a crack propagating through the material, as is well known in the art. - The illustrated
strap 12 has astrap width 58 less than theslit width 82, but greater than the tooth width 74. As can be seen in the illustration and understood with further discussion, thestrap 12 need not be as wide asslit 38. However the invention may have a slit that is wider (not shown), because the distance (not numbered) along the zigzag path is greater than thestraight line width 82 along the axis, and a wide strap can at least partly conform in the zigzag path. This allows a variety of straps to be used in combination with a variety of slits. In a preferred embodiment, thestrap width 58 is approximately 20 mm, the tooth width 74 is approximately 4 mm, and the slit width is approximately 17 mm. - As schematically shown in
FIGS. 3 and 4A ,strap 12 is a wovenfabric having pores 88 in the form of spaces betweenthreads 90 andtransverse threads 92. As thestrap 12 is pulled (FIG. 2B , andFIG. 4A ) it stretches longitudinally.Gaps 88 form betweentransverse threads 92 while theforward teeth 66 andrear teeth 70 bend and allow thewrap section 64 to travel through theslit 38, becoming theright pull 60. As longitudinal tension applied by the wearer 6 is released (FIG. 4B ), and the elastic tension in thewrap section 64 pulls back on theright end 50, at least onerear tooth 70 enters apore 88 and engages atransverse thread 92 to prevent further loosening. As seen inFIG. 4C , theaft teeth 70 and theforward teeth 66 engage thestrap 12, allowing the elasticity ofwrap portion 64 and resilience offlexible support member 16 to keep thetransparent member 14 stably positioned on the wearer'shead 5. - The figures describe the actions of the teeth of
transparent member 14 in a simple schematic way, however one should realize that a series of opposing teeth in a flexible thin material may not consistently react and align in the same way each time they are moved. Factors such as sequence of pull, direction and magnitude of pull, strap fold-over, and other factors may make the teeth orient in varying positions. However in total, theteeth strap 12 at a longitudinal position in theslit 38, as well as allow the strap to be pulled to another selected longitudinal position, within theslit 38. - Although the direction of the
strap 12 in thetransparent member 14 is shown in a preferred way, with thepulls wrap portion 64 so that the wearer can easily feel and grab the pulls, that need not be the case. The present invention will also work if the strap is threaded in the opposite direction, with thewrap portion 64 outside theright end 42 andleft end 48. It will also perform sufficiently if the threading is done in one direction on theright side 24, and the other direction on theleft side 26. The present invention, therefore, is robust and not dependent upon a consistent strap path. -
FIGS. 5A , 5B, and 5C illustrate embodiments having different slits.Slit 100 is an embodiment having anaft edge 102 with twoaft teeth 104 withpoints 73 and aforward edge 106 that does not have points 73. Instead there is astraight portion 108 on theforward edge 106, and a correspondingstraight portion 110 on theaft edge 102.Slit 200 is an embodiment in which therear edge 202 has at least onetooth 266 with apoint 73 andforward edge 206 has at least onetooth 270 with apoint 73.Slit 300 is an embodiment having truncatedteeth teeth FIG. 3 , except thatsharp points 73 are cut off. This may be done, for example, at the same time as the punching of the relief holes 84, or may be done at a different time in the manufacturing process. A reason fortruncated teeth -
FIG. 6 illustrates aface shield 400 havingteeth strap having pores 88, instead strap 402 may be made of a material without pores. The strap material may be, for example, foam or film having aninside surface 402 and anoutside surface 404. As seen inFIG. 6 , thepoints 73 ofteeth strap 402 at a selected position by poking anddepressing surfaces Pores 88 are not necessary. Because the teeth do not need to be sized to enter pores, they may instead betruncated teeth FIG. 5C , or rounded, or any other shape. An optimum shape may be chosen based on the characteristics of the selectedstrap 402, and the desired holding and release characteristics. The optimum shape may be determined experimentally, or by relationship to strap durometer, hardness, flexibility, or the like. - While the present invention has been illustrated by the description of the embodiments thereof, and while the embodiments have been described in considerable detail, it is not the intention of the applicant to restrict or in any way limit the scope of the appended claims to such detail. Additional advantages and modifications will readily appear to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details of the representative apparatus and method, and illustrative examples shown and described. Accordingly, departures may be made from such details without departure from the spirit or scope of applicant's general inventive concept.
