DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0031] Referring now to FIGS. 1-5, the thermal wrap arrangement of the present invention, generally indicated by the numeral 10, is shown. It can be seen that the wrap 10 has a main body formed of two nearly identical side portions 20, 22, releasably connected at one end by a pair of straps 24, 26 and corresponding pair of buckles 23, 25. Straps 24, 26, are evenly spaced about the center of opposing ends of the side portion 22, and are preferably connected thereto by stitching. Buckles 23, 25 are attached to a short length of straps 27, 29 formed of e.g. woven elastic, sometimes termed webbing, which straps are attached by e.g. stitching to the top edge of pocket 20 to allow for adjustment as would be apparent to one of skill in the art. The straps 27, 29 have some elasticity whereas straps 24, 26 are of a standard loop side of a hook and loop fastener or Velcro material and have limited elasticity to limit the possibility of these straps becoming permanently stretched out or elongated. Straps 24, 26 may be looped through one side of the respective buckle 23, 25 and tension can be adjusted as desired, then secured by pressing the appropriate length of strap 24, 26 onto side portion 22 as will be described in more detail below.

[0032] It should be noted that while the side portions 20, 22 are shown as rectangular, they may have any elongated or widened shape which can accommodate a side pocket which is sized to accept standard sized gel packs. The wrap 10 may be made available in incrementally increasing sizes starting from an extra small head (circumference) of approx. 18 inches or childs head up to a maximum of about 26 inches. Of course the length of the straps 24, 26 may be increased or decreased to allow for a desired amount of adjustability. In an alternative one size fits all embodiment, the side portions 20, 22 may be an intermediate size, while the straps 24, 26 are elongated to allow for adjustment from the smallest to the largest head size. The even spacing and distance between the two buckles 23,25 and the independent side loop straps 24, 26, and their adjacent hook pieces 50,52, respectively, help reduce slipping of the device, and twisting of the wrap 10 due to space between the two independent tensioning areas 23,24,25 and 25,26,52 is wide enough to accommodate an extra-large head shape and size, and also, small enough where it can curve around an extra small head (3 year old or even smaller). It can be appreciated that more than two straps 24, 26 and their respective tensioning components 23,25 and 50,52 may be employed, especially for larger sizes of the wrap.

[0033] In a preferred embodiment, the wrap 10 is made primarily from a polyester or polyester/spandex, or nylon/spandex material or any synthetic material which has a slight elasticity, except as otherwise noted herein. Also, the material is preferably treated with anti-microbial agents, and is woven to be quick drying. A material such as recycled polyester may be ideally used for this purpose. Alternatively, the wrap 10 may be made from terrycloth, bamboo, cotton, nylon, or other synthetic or natural material but less expandable material, with some loss of conformance to the users head shape. Therefore a combination of spandex or lycra with any of the aforementioned materials could also be substituted for the material.

[0034] Referring specifically to FIGS. 2 and 3, it can be seen that each side portion 20, 22 has both inner and outer sheets 30, 32 which are unattached along their respective top edges 36, 35 and thereby form a pocket 38 into which a gel pack 39 may be inserted. An additional inner sheet 34 is attached to inner sheet 30 and is essentially a thermal transfer sheet as the gel pack 39 radiates thermal energy therethrough. The additional inner sheet 34 helps to limit the amount of thermal energy transferred to the user to prevent frostbite or other injuries which may occur as a result of excessive cold or heat applied to the user's skin. Thicker material may be used for inner and outer sheets 30, 32 in which case a single layer of material may be used for inner sheet 30 thereby eliminating the need for 34. The attachment of sheets 30, 32 is preferably secured by stitching, with the top, side, and bottom edges of the inner and outer sheets 30, 32 are bound together on the inside by stitching and further secured by a second stitch to enhance durability. The top edge 36 of inner sheet 30 is preferably folded over and securely stitched to thermal transfer sheet 34 as by stitches 33. If only one thicker material is used for inner sheet 30 so that 34 is not required to protect user from frostbite and/or injury from thermal transfer, the same coverstitching and/or straight stitching will be located at the top edge 36 of the inner sheet to clean finish the raw edge of the pocket bags. Although side pockets 38 may be wide enough so that the gel pack 39 may be slid horizontally, as well as tall enough to slide in different size gel packs or thermal compresses to adjust the region to which thermal energy is transferred, in a preferred embodiment the gel pack 39 is sized to fill the entire pocket 38.

[0035] The bottom edges 42 of the side pocket envelopes are connected by a chin strap portion 44, which is formed of primary 45 and secondary 47 straps. The primary chin strap 45 is relatively wide to ensure that inner and outer sheets 30, 32 are stretched taut about the mandibular region of the user's face, and is preferably about half the width of the side pockets 38. The primary chin strap 45 is made of the same material as the bulk of the wrap 10, namely, a polyester, nylon, or other fabric that can have a stretch material namely spandex or lycra. The secondary chin strap 47 is attached centrally (widthwise) to the bottom edge 42 of side portion 20 and is relatively narrow, about a third of the width of the primary chin strap 45, and centrally positioned relative to the position of straps 24, 26. The secondary strap 47 is made from a strip of Velcro loop material or a generic hook and loop fastener, specifically the loop side of the hook and loop fastener, and is therefore not elasticated. The sizing of the chin strap portion 44 relative to the width of the pockets 38 overcomes a tendency common in prior art thermal wraps where bunching or other fabric deformations due to a single, relatively narrow (widthwise) strap lead to an uneven application of the thermal treatment. Also, prior art wraps having a chin strap substantially as wide as the pockets will have a tendency to cause deformation or sagging of the pocket material when the gel pack or compress is inserted which is rectified by the added secondary tension strap 47, when placed around the user's head, neck or face. The positioning of the chin strap portion 44 in the present inventive wrap 10 allows for tensioning of the central part of the side portions 20, 22 in the lengthwise direction.

[0036] Secondary chin strap 47 is attached by stitching to the lower edge 42 of side portion 20 at one end, with the opposing end releasably attached to a lengthwise disposed strip 49 of hook material on side portion 22, so that the secondary chin strap 47 may be selectively attached, or indeed be left unattached so that 45 piece does not become reduced in size, to generate the exact amount of tension or pressure the user desires for a closely and/or comfortably conforming fit.

[0037] Side portion 22, which may be designated the primary treatment or target side portion 22 if the user desires only one gel pack be used for therapy includes an opposing pair of elongated vertically disposed strips 50, 52 of hook or loop type fastening material positioned in spaced parallel relation on outer sheet 32. The strips 50, 52 may extend at least halfway, lengthwise, down the side portion 22 and are sized for releasable substantially overlapping engagement with straps 24, 26. The spacing of the strips 50, 52 corresponds to the width of the placement of straps 24 and 26 so that when standard gel pack 39 is inserted into pocket 38 strips 50, 52 are positioned to apply even pressure to the body region where the wrap 10 is being applied and the lateral edge regions 41 of the gel pack via straps 24, 26. The lateral displacement of straps 24, 26 causes lateral stretching or tension which further conforms the wrap 10 to the contours of the user's face, head or neck. Thus, the positioning of the strips 50, 52 allows for both lateral and lengthwise tensioning of the target side portion 22 of the wrap 10 when straps 24, 26 are attached thereto. Lengthwise tensioning is further aided by the relatively short straps 27, 29 which are attached to straps 24, 26 via buckles 23, 25, the short straps 27, 29 being formed of highly elastic material as previously mentioned. It should be noted that since the straps 27, 29 are short, overtime any elastic or static/non stretch material which may become deformed as might occur with any elastic material, it will not reduce the effectiveness of the tensioning system by straps and attachments 24, 26, 50, 52, 45, 47 and 49. The limited thickness of the gel pack 39 (as opposed to e.g. ice) allows for some deformation thereof, while the inner and outer 30, 32 sheets stretch material has resilience to continue to provide the ability to conform to the contour of the user's face, neck or head. It should be noted that this is accomplished without the use of any laterally extending straps.

[0038] It can be seen that straps 24, 26 are elongated to extend nearly the entire length of side pocket 22 to allow for extra-large adult size head, face or neck. This configuration allows for a wide range of adjustability of the wrap 10 while also compressing and deforming the gel pack 39 both laterally and lengthwise relative to how it is being applied (head, and neck as opposed to face) on the target side 22 of the wrap due to the action of straps 24, 26, and the chin strap 44 and tensioning secondary strap 47, respectively, as described above.

[0039] Referring now especially to FIG. 13, it can be seen that each pocket 38 has a closure 43 formed at its top end, the closure formed by cooperating hook and loop fastener patches 62, 64 respectively, positioned on inner 34 and outer 32 sheets respectively. The closure 43 functions to keep the gel pack 39 in position for application to the targeted treatment area while also preventing accidental dislodgement. Both hook and loop fastener tabs 62, 64 are attached via box stitching 68, 70. The box stitching that has a diagonal stitch to enhance strength, or alternatively can be secured by an edge stitch around the perimeter of each tab, and reinforced with a stich placed directly over the underlying stitch along the perimeter stitching since repeated detachment of the patches 62, 64, which action places considerable stresses on the central portion of the patches, can cause premature failure of the closure 43. The tabs 62, 64 need to be secured by stitching through sheets 34, 30, and 31, 32 respectively, in order for the structure to retain integrity.

[0040] While the wrap 10 is effective for applying heat/cold to the mandibular region of the face, head, or neck, it is equally effective for applying thermal energy to any part of the human body due to the combination of the tensioning of straps 24, 26, going through buckles 23,25, and attaching to pieces 50,52, as well as the adjustable tension system area 45,47, and 49 as well as the resilience of the elastic material. It should be noted that since there is tensioning in three areas of the device, it would not be entirely required to have elasticity in the material being used for the wrap and still achieve an effective tension for contouring to the body. FIGS. 6-12 show the wrap deployed in various positions about the user's head and neck.

[0041] Referring particularly to FIGS. 6-8 the wrap 10 is shown positioned about the crown of the user's head. It should be noted that the wrap can also be positioned so that side portion is placed under the chin while the opposite side portion holds a thermal gel pack to the top of the users head. In this deployment around the forehead and/or crown of the user's head, the wrap 10 is effectively shortened in the length direction by folding over chin strap 45 and using secondary tension strap 47 to pull end portions 42 of the pockets 20, 22 into close proximity. When the portions 20,22 are brought together by strap 47, a more seamless thermal application or continuous thermal coverage of achieved. As the circumference of the wrap 10 is reduced, there is an excess length of straps 24, 26 which may be tucked under the wrap 10 as shown in FIG. 8.

[0042] Referring particularly to FIGS. 10-12, the wrap 10 is shown positioned about the user's neck area. The circumference of the wrap is shortened by again folding chin strap 45 with the secondary tension strap 47, and the excess area can be eliminated by additionally deploying straps 24, 26 which attach to 50, 52. The unused ends of the straps once the wrap 10 has been positioned can then be tucked into edge 42 of pocket 22 to prevent dangling thereof, which dangling could interfere with the comfort and safety of the user.

[0043] FIG. 14 illustrates deployment of the wrap about the user's mandibular area, cheeks and/or temporomandibular region of the head. After inserting the frozen or heated gel packs 39 into pockets 38 and securing them using closures 43, the user places the wrap 10 about their head and begins the application and tensioning process by inserting straps 24, 26 through their adjacent buckles or tri-bar sliders 23,25, and securing them to respective hook pieces 50,52 on side portion 22. The user can further adjust the tension of the wrap by adjusting the chin piece connecting the two side portions 45 with loop strap 47 and hook fastener 49 according to their desired pressure, comfort, and/or size. The user can also draw the two side portions together so that the pockets meet using strap 47 and piece 49, for a more seamless thermal application.
