FIELD OF THE INVENTION
The subject matter of the present invention relates generally to personal protective equipment (PPE) in the form a head cover worn by health care professionals.
BACKGROUND
Health care professionals often wear a surgeon's cap, a bouffant cap (i.e., hair net), or both during medical procedures to prevent contact with hazardous materials such as blood or other bodily fluids. In addition, health care professionals are often required to wear a surgeon's cap or a bouffant cap (i.e., hair net) to cover their hair to protect the sterile environment. Moreover, the Association of Registered Nurses (AORN) Guidelines are undergoing revisions, and it is now recommended that head coverings should cover the head, hair, ears, facial hair, and nape of the neck to not only protect health care professionals but to maintain a sterile environment as well. However, traditional surgeon's caps do not cover the ears or the nape of the neck, requiring health care professionals to also don a bouffant cap or hair net to try to cover these regions. Bouffant caps add an additional layer of PPE which can trap heat and increase bulk. Further, bouffant caps are prone to leave red marks and indentations on the forehead after use due to the use of an elastic band to secure the bouffant caps around the head.
One solution is to don a bouffant cap only instead of a bouffant cap and surgeon's cap. However, bouffant caps generally cannot support the use of headlamps or other equipment that may be used by a health care professional. Hence, it is necessary to don both a bouffant cap and a surgeon's cap, as the surgeon's cap has sufficient bulk and structure to support headlamps and other equipment. Nevertheless, problems also exist with the use of a surgeon's cap. Namely, typical surgeon's caps only come in a few sizes and do not provide a secure enough fit for many health care professionals. In addition, although surgeon's caps may be outfitted with ties, the repetition of tying a surgeon's cap to secure its fit over an extended time period can lead to shoulder pain and other issues.
Consequently, there is a need for a head cover that overcomes the aforementioned shortcomings of existing surgeon's caps and bouffant caps. In particular, a head cover that covers a health care professional's hair without the need to wear a surgeon's cap and a full bouffant cap would also be useful.
SUMMARY
The present invention is directed to a head cover. The head cover includes a surgical cap portion and a bouffant cap portion. The surgical cap portion includes a top surface and a side panel secured to the top surface via a seam. Further, the bouffant cap portion is secured to a rear portion of the side panel, where the bouffant cap portion is maintained against the rear portion of the side panel in an undeployed state and is deployable from the rear portion of the side panel to contain a wearer's hair.
In one particular embodiment, the side panel can be a continuous section of material that completely encircles the circumference of the top surface, further wherein a series of pleats, an elastic band, or both are present adjacent a lower edge of the side panel. Further, the series of pleats, the elastic band, or both can be present at the rear portion of the side panel or below an ear portion of the side panel.
In addition, when the series of pleats, the elastic band, or both are present at the rear portion of the side panel, the bouffant cap portion can be positioned above the elastic band, the series of pleats, or both by a distance D. For instance, the distance D can range from about 0.25 centimeters (cm) to about 6 cm.
In one more embodiment, an exterior flap can contain the bouffant cap portion of the head cover until the bouffant cap portion of the head cover is deployed.
In still another embodiment, the side panel can extend between a first end and a second end, wherein a fastening means can be disposed on the first end or the second end. Further, the fastening means can include hooks, loops, or a combination thereof.
In yet another embodiment, the bouffant cap portion can have a circumference, wherein a series of gathers are present at the circumference of the bouffant cap portion. Moreover, a part of the circumference of the bouffant cap portion can be secured to a body-facing surface of the rear portion of the side panel.
In yet another embodiment, the top surface of the surgical cap portion can be adjacent the wearer's head.
In an additional embodiment, the bouffant cap portion of the head cover and the top surface of the surgical cap portion do not overlap.
In one more embodiment, the bouffant cap portion of the head cover is not visible until it is deployed.
In one particular embodiment, the side panel of the surgical cap portion can include a laminate. For instance, the laminate can be a spunbond-meltblown-spunbond material.
In one more embodiment, the side panel of the surgical cap portion can include a spunbond material or a cotton woven material.

DETAILED DESCRIPTION
Reference now will be made in detail to embodiments of the invention, one or more examples of which are illustrated in the drawings. Each example is provided by way of explanation of the invention, not limitation of the invention. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope or spirit of the invention. For instance, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents.
Generally speaking, the present invention is directed to a head cover that can be worn by health care professionals. The head cover includes a surgical cap portion and a bouffant cap portion. The surgical cap portion includes a top surface and a side panel secured to the top surface via a seam. Further, the bouffant cap portion is secured to a rear portion of the side panel, further wherein the bouffant cap portion is maintained against the rear portion of the side panel in an undeployed state and is deployable from the rear portion of the side panel to contain a wearer's hair. As such, the head cover enables a wearer to secure his or her hair inside the bouffant cap portion as needed, yet bouffant cap portion does not cover the wearer's entire head, which minimizes the amount of heat that is trapped within the head cover and increases the level of comfort for the wearer. Furthermore, because the bouffant cap portion is only present at the lower edge of the surgical cap portion, the bouffant cap portion does not leave red marks on the wearer's forehead, which is a problem associated with current head covers. In addition, because the head cover also incorporates a surgical cap portion, the head cover has sufficient structure to support a headlamp or any other accessory that the wearer may need to wear around his or her head during a medical procedure, while a bouffant cap alone may shift or become unstable and hinder the use of such accessories. Moreover, because the head cover can utilize a fastening means such as hooks, loops, or a combination thereof, or because the head cover can include an elastic band secured to a continuous side panel of the surgical cap portion to ensure a snug yet comfortable fit, the need to use ties to secure the head cover is eliminated, which can minimize the occurrence of shoulder pain experienced by many health care professionals due to the repetitive motion of tying. The specific features of the head cover of the present invention may be better understood with reference to FIGS. 1-10.
Referring now to FIG. 1, one embodiment of a head cover 100 contemplated by the present invention is shown before the head cover 100 has been donned and secured about the head of a wearer. The head cover 100 has an anterior portion 118 that is positioned about a forehead of a wearer and a posterior portion 120 that can be secured about the back of the head or neck of the wearer. The head cover 100 also includes a surgical cap portion 102 and a bouffant cap portion 104. The surgical cap portion 102 includes a top surface 114 and a side panel 116. In one embodiment, the top surface 114 and the side panel 116 can be joined together at a seam 106 that encircles the circumference 140 of the top surface 114. The side panel 116 extends between a first end 130 and a second end 132. The first end 130 includes a fastening means 110, which can be in the form of hooks, loops, or a combination thereof, or any other suitable fastening mechanism such as a tape, adhesive, etc. Moreover, it is to be understood that although the fastening means 110 is shown as being present on the first end 130, the fastening means 110 could be present on the second end 132 in the alternative, or both the first end 130 and the second end 132 could include the fastening means 110.
Turning now to the bouffant cap portion 104, the bouffant cap portion 104 is shown in an undeployed state 104a in FIG. 1, where the bouffant cap portion 104 includes gathers 108 and is folded into position against the side panel 116. The bouffant cap portion 104 is secured to the side panel 116 towards the posterior portion 120 of the head cover 100 and is positioned near a lower edge 144 of the side panel 116. The manner in which the bouffant cap portion 104 can be deployed to contain a wearer's hair is discussed in more detail with respect to FIGS. 2 and 3.
Specifically, FIG. 2 is a side view of the head cover 100 of FIG. 1 after it has been donned by a wearer 112, while FIG. 3 is a side view of the head cover 100 of FIG. 1 after the bouffant cap portion 104 of the head cover has been deployed from the posterior portion 120 of the surgical cap portion 102 of the head cover 100. As shown in FIG. 2, the side panel 116 wraps around the wearer 112's head 146 such that the first end 130 is secured to the side panel 116 via the fastening means 110 near the posterior portion 120 of the head cover 100. Further, the bouffant cap portion 104 is in an undeployed state 104a and is contained within the side panel 116 at edge 144 such that the bouffant cap portion 104 is not visible. The edge 144 of the side panel 116 encircles the wearer 112's head and covers a portion of the wearer 112's ear 122.
Next, FIG. 3 shows the head cover 100 after the bouffant cap portion 104 has been used to contain the wearer 112's hair such that the bouffant cap portion 104 is in a deployed state 104b. As shown, the bouffant cap portion 104 extends beyond the edge 144 of the side panel 116 so as to contain hair that may extend outside the surgical cap portion 102 of the head cover 100. The circumference 142 of the bouffant cap portion 104 contains gathers 108 that provide the bouffant cap portion 104 with some elasticity to enable the bouffant cap portion 104 to securely contain the wearer 112's hair. The bouffant cap portion 104 can be deployed in any suitable manner, such as by the wearer 112 grasping the gathers 108 and gently pulling downward to secure the bouffant cap portion 104 around his or her hair.
FIG. 4 is a side view of another embodiment of a head cover 200 after it has been donned by a wearer 112, while FIG. 5 is a side view of the head cover 200 of FIG. 4 after the bouffant cap portion 104 of the head cover has been deployed from the posterior portion 120 of the surgical cap portion 102 of the head cover 100. As shown in FIG. 4, the side panel 116 wraps around the wearer 112's head 146 such that the first end 130 is secured to the side panel 116 via the fastening means 110 near the posterior portion 120 of the head cover 102. Further, the bouffant cap portion 104 is in an undeployed state 104a and is contained within the side panel 116 at edge 144 such that the bouffant cap portion 104 is not visible. The edge 144 of the side panel 116 encircles the wearer 112's head and is designed such that it covers the entirety of the wearer 112's ear 122. Further, the side panel 116 can include an ear portion 124 that is formed from a different material than the remainder of the side panel 116. For instance, the ear portion 124 can be formed from a material that is thinner than the rest of the side panel 116 so as to not obstruct the wearer's ability to hear when wearing the head cover 200.
Next, similar to FIG. 3 described above, FIG. 5 shows the head cover 200 after the bouffant cap portion 104 has been used to contain the wearer 112's hair such that the bouffant cap portion 104 is in a deployed state 104b. As shown, the bouffant cap portion 104 extends beyond the edge 144 of the side panel 116 so as to contain hair that may extend outside the surgical cap portion 102 of the head cover 100. The circumference 142 of the bouffant cap portion 104 contains gathers 108 that provide the bouffant cap portion 104 with some elasticity to enable the bouffant cap portion 104 to securely contain the wearer 112's hair. The bouffant cap portion 104 can be deployed in any suitable manner, such as by the wearer 112 grasping the gathers 108 and gently pulling downward to secure the bouffant cap portion 104 around his or her hair.
FIG. 6 is a side view of the head cover 300 after it has been donned by a wearer 112, while FIG. 7 is a side view of the head cover 300 of FIG. 6 after the bouffant cap portion 104 of the head cover has been deployed from the posterior portion 120 of the surgical cap portion 102 of the head cover 100. As shown in FIG. 6, the side panel 116 is a continuous piece of material that wraps around the wearer 112's head 146 such that a fastening means 110 as in FIGS. 1-5 is not required to secure the head cover 300 on the wearer 112's head 146. Instead, the head cover 300 includes an elastic band 134 and pleats 126 formed in a securing rear portion 136 of the side panel 116 (see FIGS. 8, 9a, 9b, and 10) to ensure a secure fit around the wearer 112's head 146. In addition, the bouffant cap portion 104 is in an undeployed state 104a and is contained within the side panel 116 at edge 144 via an exterior flap 138 such that the bouffant cap portion 104 is not visible when in an undeployed state. As shown, the edge 144 of the side panel 116 can encircle the wearer 112's head and covers a portion of the wearer 112's ear 122.
Next, FIG. 7 shows the head cover 300 after the bouffant cap portion 104 has been used to contain the wearer 112's hair such that the bouffant cap portion 104 is in a deployed state 104b. As shown, the bouffant cap portion 104 extends below the exterior flap 138 beyond the edge 144 of the securing rear portion 136 of the side panel 116 so as to contain hair that may extend outside the surgical cap portion 102 of the head cover 300. The circumference 142 of the bouffant cap portion 104 contains gathers 108 that provide the bouffant cap portion 104 with some elasticity to enable the bouffant cap portion 104 to securely contain the wearer 112's hair. The bouffant cap portion 104 can be deployed in any suitable manner, such as by the wearer 112 reaching underneath the exterior flap 138 and grasping the gathers 108 and gently pulling downward to secure the bouffant cap portion 104 around his or her hair.
Referring now to FIGS. 8, 9a 9b, and 10, the securing rear portion 136 of the side panel 116 of FIGS. 6 and 7 is shown in more detail. Specifically, FIG. 8 is a cross-sectional view of part of the posterior portion 120 of the head cover 300 of FIG. 6, including an exterior flap 138 and a securing rear portion 136 of the side panel 116, where the exterior flap 138 includes an undeployed bouffant cap portion 104a and the securing rear portion 136 includes an elastic band 134 and a series of pleats 126.

Specifically, FIG. 17 is a side view of a head cover 600 according to another particular embodiment of the present invention illustrating a deployed bouffant cap portion 104b at the rear portion 120 of the surgical cap portion 102 of the head cover 600, where the side panel 116 includes a pair of ties 156. Although only one tie 156 is shown in FIG. 17, it is to be understood that the opposing portion of the side panel 116 also includes a tie 156. The pair of ties 156 can be secured to the side panel 116 via a seam 158 or any other suitable attachment means such as an adhesive, hook and loop closures, ultrasonic bonding, double-sided tape, etc. FIG. 18 illustrates a rear-side view of the head cover 600 of FIG. 17 showing the pair of ties 156 secured about the rear portion 120 of the surgical cap portion 102 of the head cover 600. Meanwhile, FIG. 19 is a rear view of the head cover 600 of FIG. 17 showing how the seam 148 is not visible along the entire surgical cap portion 102, as part of the side panels 112 at the rear portion 120 of the surgical cap portion 102 is folded over itself as a result of the secure fit provided by the pair of ties 156.
Further, FIG. 20 is a side view of a head cover 700 according to another particular embodiment of the present invention illustrating a deployed bouffant cap portion 104b at the rear portion 120 of the surgical cap portion 102 of the head cover 600, where the side panel 116 includes a pair of ties 156. Although only one tie 156 is shown in FIG. 17, it is to be understood that the opposing portion of the side panel 116 also includes a tie 156. The pair of ties 156 can be secured to a lower edge 144 of the side panel 116 via a seam 158 or any other suitable attachment means such as an adhesive, hook and loop closures, ultrasonic bonding, double-sided tape, etc.
Without intending to be limited by any particular theory, the present inventors have found that the pair of ties 156 can increase the security of the head cover 600 on the wearer's head. It is believed that the added tension from the pair of ties 156 helps to secure the head cover 600 against the wearer's forehead and prevent the head cover 600 from sliding up or down during use, while at the same time not being too tight or uncomfortable.
Regardless of the particular configuration of the surgical cap portion 102 and bouffant cap portion 104 of the head cover 100, 200, 300, 400, 500, or 600 of the present invention, the materials used to form the surgical cap portion 102 and bouffant cap portion 104 can be chose to maximize the comfort to the wearer. For instance, the top surface 114 and the side panel 116 of the surgical cap portion 102 can be made from a variety of nonwoven materials formed by any number of processes including, but not limited to, air laying processes, wet laid processes, hydroentangling processes, spunbonding, meltblowing, staple fiber carding and bonding, and solution spinning. The fibers in the nonwoven materials themselves can be made from a variety of both natural and synthetic materials including, but not limited to, cellulose, rayon, nylon, polyesters, polyolefins, and many other materials. The fibers may be relatively short, staple length fibers, typically less than three inches, or longer and substantially more continuous fibers such as are produced by spunbonding and meltblowing processes.
In one particular embodiment, the top surface 114 of the surgical cap portion 102 and the bouffant cap portion 104 can be formed from a spunbond material to facilitate air flow and minimize the amount of heat trapped within the head cover 100, 200, or 300. In addition, the ear portion(s) 124 of the side panel 116 can also be formed from a spunbond material. Meanwhile, the side panel 116 of the surgical cap portion 102 can be formed from a laminate material such as a spunbond-meltblown-spunbond material is made from three separate layers that are laminated to one another in order to provide sufficient structure to support a headlamp or any other accessories that might be worn about the crown of the head by a health care professional. The method of making the aforementioned materials is known and described in U.S. Pat. No. 4,041,203 to Brock, et al., which is incorporated herein in its entirety by reference. The material of Brock, et al. is a three layer laminate of spunbond-meltblown-spunbond layers that is also commonly referred to by the acronym “SMS.” The two outer layers of SMS are a spunbond material made from extruded polyolefin fibers, or filaments, laid down in a random pattern and then bonded to one another. The inner layer is a meltblown layer also made from extruded polyolefin fibers generally of a smaller diameter than the fibers in the spunbond layers. As a result, the meltblown layer provides increased barrier properties due to its fine fiber structure, which permits the sterilizing agent to pass through the fabric while preventing passage of bacteria and other contaminants. Conversely, the two outer spunbond layers provide a greater portion of the strength factor in the overall laminate. The laminate may be prepared using an intermittent bond pattern that is preferably employed with the pattern being substantially regularly repeating over the surface of the laminate. The pattern is selected such that the bonds may occupy about 5% to about 50% of the surface area of the laminate. Desirably, the bonds may occupy about 10% to about 30% of the surface area of the laminate. Further, although the head cover 100, 200, or 300 is described above as being formed from a combination of spunbond and SMS materials, is to be understood that the different portions of the head cover 100, 200, or 300 can be made from any other suitable materials that minimize the trapping of heat yet provide sufficient structure as needed. For instance, in addition to the spunbond or SMS materials described above, any or all of the portions of the surgical cap portion 102 (e.g., the top surface 114, the side panel 116, and/or the ear portion 124) can be formed from a woven cotton material.
This written description uses examples to disclose the invention, including the best mode, and also to enable any person skilled in the art to practice the invention, including making and using any devices or systems and performing any incorporated methods. The patentable scope of the invention is defined by the claims and may include other examples that occur to those skilled in the art.
