DETAILED DESCRIPTION
[0034] Described herein are several variations of a wearable sweat-diverting device, coupled to the wearer by a temporary adhesive mechanism. A sweat-diverting device adhered to the wearer may have several advantages over both absorbent headbands and non-absorbent sweat-diverting headbands. For example, a sweat-diverting device affixed to the wearer by a temporary adhesive such as that used in an adhesive bandage may be more comfortable to wear than a sweat-diverting headband. A sweat-diverting device held in place by an adhesive need only cover the area necessary to capture and redirect sweat, rather than circumferentially around the head. As a result, it may eliminate or mitigate problems associated with an uncomfortably tight headband fit, binding or pulling on the hair or reducing blood flow and creation of a temporary unsightly impression even after removal of a headband.
[0035] A sweat-diverting device adhered directly to a wearer may also be more effective at capturing and diverting relevant sweat which might otherwise flow or drip to the eyes. Such a sweat-diverting device may be placed such that less skin, and thus source of sweat, is exposed between the device and the eyes. In addition, a sweat-diverting device which is adhered to the wearer may be more effective at diverting sweat. A headband-based sweat diverter must be made of material strong enough to be held tightly about the head and as such needs to be thicker than an adherent sweat-diverting device. As a result of the greater thickness it may create a more substantial barrier, allowing sweat to collect above it before it drips into a collection and redirecting channel. Such larger drips may be more prone to dripping over the collection channel. In the case of a sweat-diverting device adhered directly to the wearer, the diverting channel may be formed partly by the skin of the wearer, presenting no barrier to the flow of sweat into the channel. In the case of a sweat-diverting device adhered directly to the wearer and in which the diverting channel is not formed partly by the skin of the wearer, there is nonetheless a lesser barrier than may be required by a sweat-diverting headband.
[0036] A sweat-diverting device adhered directly to the wearer may also divert sweat more effectively by enabling the diverting channel to take any convenient shape rather than to be constrained by the substantially linear shape required for a sweat-diverting headband. A sweat-diverting device adhered directly to the wearer may channel sweat downward around the eyes, rather than just laterally displaced, but still above, the eyes as in the case of a substantially linear portion of a headband. In some circumstances, such as biking, the wearer may hold his head in a downwardly inclined position. In such cases the sweat captured in a headband device would be biased to flow to the center of the forehead where it may overflow the channel. A sweat-diverting device adhered directly to the wearer may be positioned such that the lateral ends of the channel may be sloped downward from the center, allowing outflow in the desired area.
[0037] FIGS. 1A-1C depict various devices intended to prevent flow of sweat into the eyes. FIG. 1A depicts an illustrative prior art sweatband (198), which may be exemplary of an absorbent garment used to retain sweat until it becomes saturated. FIG. 1B depicts a prior art sweat-diverting headband (199), which represents a circumferential headband approach to prevention of sweat flow to the eyes. FIG. 1C depicts one variation of a suitable wearable adhesive sweat-diverting device (101) as described hereinthroughout, that may be worn above the eyes to capture and divert sweat from reaching the eyes.
[0038] Suitable sweat-diverting devices are described in detail hereinthroughout. However, in general, the sweat-diverting devices described herein can take many forms. They may have a variety of cross-sectional configurations and shapes, be made of a variety of suitable materials, and may contain one or more additional useful features. They may also be placed in a variety of suitable locations on the face to divert sweat away from the eyes of the wearer (e.g., above the eyebrow, below the eyebrow and above the eye, etc.) and be adjusted before or during use. In addition, the sweat-diverting devices described here may be configured for a single-use and be disposable, or may be configured for more than one use and be reusable. The sweat-diverting devices may also include one or more distinctive or ornamental elements, for example, coloring, logos, or other branding. Wearable adhesive sweat-diverting devices may be supplied in lengths or coils such that a desired length may be cut off of the length or coil prior to use. The wearable sweat-diverting devices may also be configured for use with, or be coupled to, one or more devices capable of providing shade from the sun.
[0039] FIGS. 2A-2C depict one variation of an adhesive wearable sweat-diverting device (201). In the variation depicted here, the sweat-diverting device may be made of a flexible material and have a generally U or J-shaped cross section (section A-A), as illustrated in FIG. 2B. A collection channel (202) may capture sweat as it drips down the skin above the wearer's eyes. The device may be coupled to the wearer by an adhesive (203), which may be covered by a protective backing material (204) or release linear prior to use, as shown in FIG. 2C. Sweat (205) may drip into the channel (202), where it may flow to the ends (206) and down the wearer's face (207) away from the eyes. The device (201) may adhere to the wearer's face without fully circumscribing the head, and without any direct communication of one end of the device with another end of the device. For example, the device may be have a length suitable for spanning from ear to ear, temple to temple, eyebrow to eyebrow, or some length in between. In some variations the device has a length of at least 4 inches inches. In other variations the device has a length of at least 5 or at least 6 inches.
[0040] FIGS. 2D-2K depict various illustrative cross-sections of suitable for use with the sweat-diverters and devices described herein. For example, FIG. 2D provides a cross-sectional representation of diverter (210). In this variation, leg (212) curves inward. This may be useful, for example, in retaining collected sweat during head movement of the wearer, such as for example, when the wearer lowers or tilts his or her head. FIG. 2E provides another variation of a sweat-diverter (214) having a narrow opening (216), which may be useful, for example in drawing sweat into the diverter by capillary action. Opening (216) may be any suitable width capable of facilitating capillary action, e.g., between about 1 mm and about 4 mm. In addition, a sweat diverter may have one or more surface features such as grooves, raised ribs or absorbent elements placed along various portions of the device to promote channeling of sweat produced near the diverter to the ends of the device, where the sweat may then drip away from the eyes of the wearer. FIGS. 2F-2H depict another variation of a suitable sweat-diverter, here having multiple perforations or apertures (218) to facilitate outflow and capture of sweat (220) developed or collected behind the device. FIGS. 2F and 2H provide side views, while FIG. 2G provides a perspective view. While many apertures (218) are shown in this variation, any suitable number of apertures may be used. The apertures may be arranged in any suitable pattern, or may be random in their placement. FIGS. 2I-2K show illustrative dimensions for the sweat-diverter devices suitable for use herein. The spacing (S) between the legs may be configured to provide a wide spacing, and a larger channel, as depicted in FIG. 2I, or spacing (S) may be more narrow, for example, as depicted in FIG. 2K. Similarly, the lengths (L1 and L2) of the legs defining the channel may be the same, or may be different. In FIG. 2I the lengths (L1 and L2) are configured such that the ends of the legs terminate generally at equal height (H). In FIG. 2J, leg (222) extends beyond leg (224), while in FIG. 2K, leg (226) extends beyond leg (228).
[0041] FIGS. 3A-3C depict additional variations of an adhesive sweat-diverting device. FIG. 3A depicts an adhesive wearable sweat-diverting device (301) that may be made of a flexible material and have one or more pre-shaped curves to fit around (e.g., above and/or below) a wearer's eyebrows (302). The device may have a first curve, a second curve, and a third curve, wherein the first and third curves have a radius of curvature that approximate the curvature of the orbits and the second curve has a radius of curvature that approximates the curvature of the glabella. For example, one or more curves may have a radius of curvature from about 0.25 inch to about 2 inches. The device may be contoured to fit over the bridge of the nose (303) and within the orbital sockets (304). The device may further be contoured to provide outlets, with or without tubing, for carrying captured sweat at its ends (305), away from the wearer's eyes (306). The length of the device may be such that the outlets extend laterally past the eyes. In some variations, the length of the device may be from about 4 inches to about 8 inches, for example, from about 4 to 5 inches, or from about 5 to 6 inches. The device may be pre-shaped to the approximate shape required, such that it will fit most face sizes. It may also be made of a flexible material to accommodate the exact contour of a given user's face. Such flexible material may also increase the ease of application and comfort of the wearer. The curvature of the various segments may be configured to slope generally from the middle of the device, downward to the ends of the device in order to maximize the gravitational flow of sweat to the ends of the device where it may exit the device away from the eyes of the wearer.
[0042] Suitable adhesive wearable sweat-diverting devices as described herein may also be configured to be worn above each individual eyebrow, for example, as shown in FIG. 3B. Such a device may configured to run medially (308) down the side of the nose, and laterally (309) down the side of the face displaced from the eye, with a curved segment in between. Such curved segment may enable the device to conform closely to the contours of the face. Such curves may also enable the device to fit close to the eye, such that as much of the wearer's skin as possible lies above the diversion device, thereby maximizing the catchment area for sweat collection and diversion. FIG. 3C depicts an adhesive wearable sweat-diverting device (310) that may be configured to be worn above each individual eye (311) and below the corresponding eyebrow (312). Such a device may be configured to run medially (313) down the side of the nose and laterally (314) down the side of the face displaced from the eye, with a curved portion in between. Such a curved portion may enable the device to be placed below the eyebrow, thereby maximizing the catchment area for sweat collection and diversion. The curvature of the device may further enable the medial segment (313) and lateral segment (314) to terminate at a level below the eye itself, such that gravity pulls sweat into the device above and around the eye and out of the device at a level below the eye. An adhesive wearable sweat-diverting device (310) may be shaped to have one or more curves which would allow it to conform to most faces, and it may further be flexible to allow it to conform precisely to a broad variety of face contours. As mentioned above, the adhesive wearable sweat-diverting devices may come in various sizes to fit various size faces or may be adjustable to comfort by the wearer.
[0043] The wearable adhesive sweat-diverting device may be made of one or more flexible materials or be made of one or more rigid materials. In some variations it is desirable for the sweat-diverting devices to be made of one or more flexible materials and have no pre-shaped curves such that the wearer may apply it to his or her face to conform it to his or her individual features. In these variations, the sweat-diverting devices may have a first, generally linear, configuration prior to application, and a second, contoured configuration after application, set by the preference and comfort of the wearer. Suitable flexible materials for use with the devices described herein include flexible silicones, EPDM, neoprene, various butadienes, various fluoroelastomers, various thermoplastic or thermoset elastomers, various vinyl esters, combinations thereof, and the like. Suitable ranges of flexibility may include materials having hardness of 50 durometer, Shore A or less. For example, suitable durometer ranges may be between about 5 and about 50, between about 7 and about 40, between about 10 and about 30, and the like. Flexibility of the device may be enhanced by segments of varying thickness, inclusion of small slits or other apertures, or the like. When slits are included, they may run less than all the way across the device and perpendicular to the length of the device, and may be of such size to enable shaping of the device without allowing fluid to escape through them. Such slits may be 0.1 mm to 2.0 mm in width. In addition or alternatively the device may contain scored sections to increase its flexibility and shapability.
[0044] Alternatively, the sweat-diverting devices described herein may include one or more reinforcing members to help maintain the shape of the sweat-diverting device once shaped according to the wearer's preference and comfort level. For example, FIGS. 3D and E show a cross-sectional and perspective view respectively of one variation of a sweat-diverter having a reinforcing member (320). As shown there, reinforcing member (320) may be included to help shape the device prior to, or during use. In this variation, reinforcing member (320) is a wire that help maintains curve (C). While shown as a single reinforcing member, any suitable number of reinforcing members may be used. Similarly, while shown as a wire, reinforcing member may be any suitable member having greater rigidity than the diverter.
[0045] FIGS. 4A-4C depict other variations of an adhesive wearable sweat-diverting device. Adhesive wearable sweat-diverting device (401) may be made of a flexible or rigid material and may or may not have one or more angles or curves. As shown in FIG. 4B (section A-A), when applied to the wearer, a first leg (402) may form one arm of a generally V-shaped sweat-diverting channel, and the wearer's skin (403) may form the other arm of the channel. A second leg (404) of an adhesive wearable sweat-diverting device may have adhesive backing (405) for attachment of the device to the skin. As shown in FIG. 4C (section B-B), an adhesive wearable sweat-diverting device (406) may have adhesive backing (407) on one leg (408) for coupling the device to the wearer's skin (409). The adhesive backing (407) may be positioned on one leg (408) such that the leg may extend away from the skin without sticking to a facial feature such as an eyebrow (410). A second leg (411) of an adhesive wearable sweat-diverting device may extend at an angle from the first arm to form a barrier against the flow of sweat and one side of a sweat-diverting channel. The wearer's skin (412) may form another side of the sweat-diverting channel.
[0046] FIGS. 5A and 5B depict other variations of an adhesive wearable sweat-diverting device. Adhesive wearable sweat-diverting device (501) may be made of a flexible or stiff material, or a combination thereof, and may have one cross-section at one segment (502) of the device and another cross-section (503) at another cross section of the device. As illustrated in FIG. 5A, the adhesive wearable sweat-diverting device (501) may have a generally U-shaped cross section in a segment positioned to capture and divert sweat from reaching the eyes, and a generally circular cross-section in a segment positioned to divert sweat captured in another segment of the device, although, as described in detail below, additional cross-sections may be used. Such a transition in cross-section may enable a first segment of the device to perform at least one function, and a second or other segment to perform at least one function different from a function performed by the first segment. FIG. 5B illustrates an adhesive wearable sweat-diverting device (504) that may have at least one segment (505) adhesively coupled to the wearer and at least one other segment (506) not adhesively coupled to the wearer, e.g., not coupled to the wearer.
[0047] One example of an adhesive wearable sweat-diverting device (601) which has at least one segment not adhesively coupled to the wearer is depicted in FIGS. 6A-6C. In one variation, the adhesive wearable sweat-diverting device (601) may have a first segment (602) with a generally U-shaped sweat-diverting channel in a portion that may be positioned above the wearer's eye, and a second or other segment (603) with a generally circular cross-section that may traverse the wearer's face and some of the wearer's hair. Such second or other segment may have at least one area (604) in which it is not adhesively coupled to the wearer so that it does not stick to the wearer's hair. The third or other segment may be positioned (605) to release captured sweat in an area where it may not irritate the wearer, such as behind the ear or back of the neck (606), as shown in FIG. 6C. A segment (607) of such a device may have a cross-section in a generally accordion shape in order to enable it to maintain a shape or directionality defined by the wearer (FIG. 6B). A first portion (602) of such device may have a preformed curve, which may be shaped to fit within the orbit and against the lateral side of the nose. Such preformed curved section (602) may further be partially deformable so that the device may fit wearers with different size orbits.
[0048] As mentioned above and described hereinthroughout, the sweat-diverting devices described herein may include one or more additional useful features. For example, FIGS. 7A-7C illustrate various sweat collecting channels of suitable sweat-diverting devices comprising one or more additional useful features. FIGS. 7A and 7B depict a channel (701) having a wicking or other absorbent material (702), e.g., a polymer wicking material. While shown in FIG. 7A as positioned such that it may guide sweat captured by the channel along the bottom of the channel (703) to prevent sweat from leaking out of the channel other than at the end of the channel (704), the absorbent material may be placed in any suitable location (e.g., at the top of the device (708) or at or near the outer bottom of device (709)). Alternatively the absorbent material may be placed outside the channel, for instance below the channel, to absorb and redirect sweat produced below the level of the device in use. Alternatively or additionally, a channel (705) may have a membrane or filter cover (706) which may allow sweat (707) to enter the channel and make it relatively more difficult for sweat to exit the channel in the reverse direction (FIG. 7C).
[0049] FIGS. 8A-8D depict several attachment mechanisms for use with the sweat-diverting devices described herein, for example, device (801). As shown in FIG. 8A, an adhesive attachment mechanism (802) may be applied at the time of manufacture and may be covered with a protective backing material or release liner (803) until the time of use. FIG. 8B depicts a flexible strip (804) with adhesive on one side, which may be applied at the time of manufacture or by the user prior to use, and the strip may have at least one portion where the adhesive is covered by a protective backing material (805) until the time of use. A wearable sweat-diverting device that has an adhesive mechanism applied at the time of manufacture may be intended for single use before disposal. For example, as illustrated in FIG. 8C, a wearable sweat-diverting device (806) intended for multiple uses prior to disposal may have an adhesive mechanism applied by the user at the time of use. An adhesive mechanism (807) may be a flexible strip (808) coated with adhesive on both sides, and the adhesive may be covered with protective backing material (809, 810) which may be removed prior to use. A first piece of backing material (809) may be removed first and the adhesive strip applied to the wearable sweat-diverting device (806). A second piece of backing material (810) may then be removed to expose the other adhesive surface, and the wearable sweat-diverting device applied to the wearer. FIG. 8D depicts a wearable sweat-diverting device (811) that may be used multiple times prior to disposable. The sweat-diverting device (811) may be attached to a wearer using a gel-based adhesive (812) mechanism, where the gel-based adhesive may be applied by the user at the time of use or integrated into the device at the time of manufacture. In some variations, the device may incorporate an adherent material that retains its adhesive properties over multiple uses. Other suitable adhesive materials include pressure sensitive adhesive materials, such as synthetic rubber/resin blends and acrylates, both of which are available from 3M. It should be understood that the adhesive need only cover various portions of the leg attaching to the wearer.
[0050] In some embodiments, an adhesive device may be configured to provide shade over the eyes, with or without a sweat-diverter. In some variations, the device is an adhesive sweat-diverting device configured to provide shade to the eyes. Such a device may comprise a shade element which may extend substantially perpendicularly from the face of the wearer and which may create a shade over the eye or eyes, for example, as schematically depicted in FIG. 9 and FIGS. 10A-10C, and FIGS. 12C and 12F. For instance, shade elements (900), (1000), (1207), and (1213) may protrude from the face of the wearer at an angle from about 45 to about 135 degrees. For example, about 45 to about 90 degrees, or about 90 degrees to about 135 degrees. In some variations, the angle is about 90 degrees. In some variations, the angle may be adjusted by the wearer during use (e.g., to accommodate changes in the wearer's position relative to the sun), or the angle may be pre-determined and fixed. Shade elements may be wide enough to shade both eyes (e.g., shade element (900)), or may be wide enough to shade only one eye (e.g., shade element (1000)). The shade elements (1000) of the adhesive sweat-diverting device illustrated in FIGS. 10A-10C may each have a curve that approximates the curvature of the eyes, which may help provide better shading from the sun. The length of the shade elements (900), (1000), (1207), and (1213) may be any suitable length such that the shadow it creates overlaps with the eye region of the wearer, or it may be adjustable by the wearer by tearing or cutting to a suitable length. The shade elements may be perforated for the purpose of enabling the tearing of the device to a desired length. Adhesive sweat-diverting devices with one or more shade elements may be sized and shaped to adhere to the wearer's skin in any of the positions described previously. For example, an adhesive sweat-diverting device may be positioned above the eyebrows, as shown in FIG. 9. Alternatively, adhesive sweat-diverting devices may be positioned between the eyebrows and the eyes, as shown in FIGS. 10A-10B. In some variations, the adhesive portions may be similar to one or more of the adhesives described above. For example, the adhesive portions (904), (1004) may comprise the entire skin-contacting surface of the device. Such a continuous adhesive region may help ensure that the device is securely attached to the wearer and may create a seal such that sweat does not leak into the wearer's eyes. Sweat-collection and/or sweat-diverting channels, such as sweat-collection channel (902) shown in FIG. 9, may be of any suitable configuration, as described above. For example, sweat-collection channel (902) may have a U-shaped shaped cross-section or a V-shaped cross-section, as depicted and described previously.
[0051] In other variations, adhesive sweat-diverting devices may not have a discrete sweat-collection or sweat-diverting channel, but may have one or more shade elements that are curved such that sweat is diverted away from the wearer, and across the contour of upper surface of the shade element(s). Such devices are depicted in FIGS. 11A-C and FIG. 12A, FIG. 12B, FIG. 12 D, and FIG. 12E. As with all the devices described here, these devices may or may not have a continuous adhesive seal to the skin of the wearer. For example, the devices described here may have only intermittent adhesive portions. Since such adhesive shade devices do not circumscribe the head and only extend across a portion of the wearer's face, these adhesive shade devices may be positioned closer to the eyes (e.g., just above the eyebrows, and/or between the eyebrows and the eyes, etc.) if desirable. This may help to provide better shading from the sun. The device depicted in FIGS. 11A-11C has a width such that shade is provided to both eyes, but in other variations, the device may have a smaller width that is suitable for providing shade to just one eye and used in pairs, as shown in FIG. 10A. While these devices have been described and depicted as providing shade to the eyes, it should be understood that these devices may also be configured to shade other parts of the body, as may be desirable. For example, these devices may be configured to provide shade to the ears, nose, back of the neck, or any region of the arms or legs. These devices may also be used to shield and/or provide shade to sensitive regions of the body, for example, any cuts, scrapes, rashes, burns, areas of light sensitivity, etc.
[0052] While FIGS. 11A-11C depict a variation, where the device provides shade substantially in the form of a visor, the shading portion of the device need not be that long, as seen for example, in the devices shown in FIGS. 12A-12F. FIG. 12A-12C depict a two-layered sun shade (1200) having off-set slots or tabs in each layer. The slots or tabs may or may not be made from one or more perforations or slots in the sun shading portions, and these portions may or may not be made from the same material or have the same thickness, width, or orientation. FIG. 12A shows a cross-sectional view of shade (1200), having two layers of off-set tabs (1202, 1204) and FIG. 12B provides a perspective view of shade (1200).
