PILLOW

BACKGROUND

This document relates to a pillow. Individuals generally exhibit varying tendencies to snore when asleep. Individuals with a greater tendency to snore may experience less restful sleep and may impact upon the ability of others to sleep comfortably. Snoring may be caused by vibration of obstructive tissue in the airway, e.g., the soft palate and/or the uvula. Snoring may also be caused by nasal obstruction with vibration of nasal tissues and/or narrowing behind the tongue with vibration between the tongue and the back of the throat.

In addressing snoring issues, individuals have investigated behavior treatment, surgical treatment, and the use of devices aimed at snoring causes and/or symptoms. Exemplary behavioral treatments have included weight loss, avoiding alcohol and sleeping pills before sleep, and avoiding sleeping on the back (e.g., by placing an object on the individual's back such as a tennis ball). Medical interventions aimed at snoring reduction typically involve removal of relevant tissue. Such procedures include somnoplasty of the palate and uvula, laser uvulopalatoplasty (LAUP), and radiofrequency ablation.

Devices aimed at snoring prevention include jaw straps that are intended to force a user's mouth to remain shut while sleeping and devices that cause a user's oral airway to remain forcibly obstructed by acting as an airflow barrier. Unfortunately, these devices can be uncomfortable and can even inflict or promote injury, including causing jaw clenching, tension headaches, and temporomandibular joint (TMJ) disorders. Other devices include nasal passage-expanding strips, which are applied to the outside of the nose and use a strong adhesive to open the nostrils wider for quieter breathing.

Other methods of reducing snoring tendencies of individuals are disclosed in, for example, U.S. Pat. No. 4,536,905 to De Santis, which discloses a pillow that includes a semi-soft brace. The De Santis brace tends to force a user's head to one side or the other, but its overall design has several disadvantages, including a potential for causing a user to experience a sore neck.

U.S. Pat. No. 4,748,702 to Sandler discloses a pillow that features two intersecting channels formed in its upper face. One channel is intended to accommodate the user's head and the other is intended to accommodate the user's neck. A relatively hard object is located in or under the first channel and also adjacent the second channel. The relatively hard object functions so as to make it uncomfortable for a user to rest the back of the user's head on the hard object, while not being relatively uncomfortable if the user moves his/her head to one side or the other. The Sandler pillow is designed so that when the user's head is on one side or the other thereof, a part of the pillow engages the user's lower jaw, causing the user's mouth to be closed.

Cervical pillows may also be used to provide support for the head and neck of a user. Such pillows sometimes include a central channel for receiving the head of a user, raised front and rear portions, and another channel of lesser depth than the first in the raised front portion for providing support for the neck of the user.

Despite efforts to date, a need remains for effective snore-reduction techniques and/or products. In addition, a need remains for techniques and/or products that improve oxygenation and/or reduce snoring behavior while simultaneously promoting effective sleep patterns. These and other needs may be satisfied by the disclosed pillow.

SUMMARY

The present disclosure is directed to a pillow that is effective in minimizing and/or eliminating a user's snoring proclivity. The disclosed pillow also contributes to better sleeping outcomes, e.g., by increasing air flow into the lungs relative to conventional pillow. In some embodiments, the pillow is effective in reducing and/or eliminating a user's snoring proclivity. In some embodiments, the pillow may contribute to better sleeping outcomes, e.g., by increasing air flow into the lungs relative to conventional pillows.

According to exemplary embodiments of the present disclosure, a pillow may include a first raised crest and a second raised crest that define a valley region therebetween. In some embodiments, a pillow may include a first raised crest and a second raised crest that define a valley region therebetween, wherein no inflection force has been exerted on the pillow. When a user positions his/her neck on the higher of the two crests (e.g., first raised crest) and his/her head in the valley defined therebetween, the user's neck, shoulders and chest are raised relative to the overall sleep surface, thereby relieving pressure on the soft palate and uvula, permitting the chest to expand more readily, and increasing/improving airflow in connection with the user's breathing activities. The angular orientation of a downwardly inclined surface between the crest(s) into the intermediate valley region may facilitate greater airflow to the lungs, which may translate to increased blood oxygen levels and a better night's sleep. In an embodiment of the present disclosure, the angle of a downwardly inclined surface between the neck-supporting crest into the intermediate valley region of the disclosed pillow is about 15°-20° relative to horizontal. Specific examples of the angle of the downwardly inclined surface may be about 15°, about 16°, about 17°, about 18°, about 19°, about 20°, or a range encompassed by any two of these values. In an embodiment, the transition surface of the pillow between the front face and the peak of the first crest is about 15°-20° relative to horizontal. In some embodiments, the angle of the transition surface may be about 15°, about 16°, about 17°, about 18°, about 19°, about 20°, or a range encompassed by any two of these values.

The disclosed pillow may be fabricated from a base foam material and an outer foam material. In some embodiments, the base foam material may exhibit a greater density than the outer foam material. Thus, for example, the base foam material may be a conventional polyurethane material exhibiting a density of about 2.75 to 3.3 lbs/ft³, and the outer foam material may be a viscoelastic foam material exhibiting a density of about 1.95 to about 2.05 lbs/ft³. Optionally, one of the first or second foam materials, or a third material, may be a gel-foam mixture that includes viscoelastic foam having gel particles dispersed throughout the foam. In some embodiments, the first, second, and/or third foam materials may be bonded or otherwise adhered to each other to define the final pillow product.

Further features and benefits will be apparent by reference to the drawings and ensuing detailed description of embodiments of the invention. The exclusive rights which are claimed are set forth in the numbered claims following the detailed description of the preferred embodiment.

No. 5,508,334, U.S. Pat. No. 5,153,254, U.S. Pat. No. 5,334,646, U.S. Pat. No. 5,239,273, U.S. Pat. No. 5,475,890, and U.S. Pat. No. 5,336,708. Each of the above references are hereby incorporated by reference.

Gel-foams may be made by blending a gel (which would be in particle form, optionally encapsulated with a material to preserve the integrity of the gel while it is suspended in the foam) with a polyol to form a blend. In some embodiments, the gel may be encapsulated before being blended with the polyol. Compositions used for encapsulating the gel may comprise polyol, fabric, plastic, elastomers, thermoplastic materials, foam, or the like. The gel particles may be dispersed and suspended throughout the foam composition.

In some embodiments, the terms “point of inflection” is used to refer to the region of the front face of the pillow positioned between the pillow's highest crest and the front face of the pillow defined by the points at which the first negative slope proximate to the first crest transitions from a decreasing negative slope to an increasing negative slope. The point of inflection is proximate to the area of the pillow identified by number 40 in FIG. 4.

In some embodiments, the “transition surface” is the region of the front face of the pillow that transitions from the sloping faces of the concave region to the convex region of the first crest. In some embodiments, the transition surface 42 comprises the point of inflection 40.

The pillow of the present disclosure is effective in minimizing and/or eliminating a user's snoring proclivity. The disclosed pillow also contributes to better sleeping outcomes, e.g., by increasing air flow into the lungs relative to conventional pillows. According to exemplary embodiments of the present disclosure, and referring to FIGS. 1-5, the pillow features a first or neck-supporting crest 34 and second crest 30 that define a valley region 24 therebetween. In some embodiments, the neck-supporting crest 34 may have an elevation that is higher than that of the second crest 30. In some embodiments, the neck-supporting crest 34 may have an elevation that is about 38% higher than that of the second crest 30.

When a user positions his/her neck over the neck-supporting crest 34 and his/her head into the valley region 24, the user's neck, shoulders and chest are raised relative to the overall sleep surface, thereby relieving pressure on the soft palate and uvula, permitting the chest to expand more readily, and increasing/improving airflow in connection with the user's breathing activities. The angular orientation of a downwardly inclined surface 32 between the crest(s) into the intermediate valley region 24 may facilitate greater airflow to the lungs, which may translate to increased blood oxygen levels and a better night's sleep. In an embodiment of the present disclosure, the angle of a downwardly inclined surface 32 between the neck-supporting crest 34 into the valley region 24 of the disclosed pillow is about 15°-20° relative to horizontal. Specific examples of the angle of the downwardly inclined surface 32 may be about 15°, about 16°, about 17°, about 18°, about 19°, about 20°, or a range encompassed by any two of these values. In an embodiment, a transition surface of the pillow between the front face 14 and the peak of the first crest 34 comprises an angle above the point of inflection 40 of about 15°-20° relative to horizontal. In some embodiments, the angle of the transition surface above the point of inflection 40 may be about 15°, about 16°, about 17°, about 18°, about 19°, about 20°, or a range encompassed by any two of these values.

In some embodiments, the disclosed pillow may be fabricated from at least a first foam layer and a second foam layer. In some embodiments, the first foam layer may comprise a core foam layer 36. In some embodiments, the second foam layer may comprise an outer foam layer 38. In some embodiments, the core foam layer 36 may exhibit a greater density than the outer foam layer 38. For example, the core foam layer 36 may comprise a conventional polyurethane foam exhibiting a density of about 2.75 to 3.3 lbs/ft³and the outer foam layer 38 may comprise a viscoelastic foam exhibiting a density of about 1.95 to about 2.05 lbs/ft³. The first and second foam layers may be bonded or otherwise adhered to each other to define the final pillow product.

FIGS. 1-5 illustrate an exemplary pillow 10 that provides improved oxygenation according to the present disclosure. The pillow 10 includes a body composed of a core foam layer 36 and an outer foam layer 38. In some embodiments, the core foam layer 36 may be a material identified by Advanced Urethane Technologies (Coldwater, Miss.) as Product 2033w and the outer foam layer 38 may be a material identified by Advanced Urethane Technologies (Coldwater, Miss.) as Product KC30010NAE. Other materials may be possible. In particular embodiments, the core foam layer 36 may comprise a high resiliency foam that provides support and the outer foam layer 38 may comprise memory foam. Memory foam generally may be made of polyurethane with additional chemicals increasing its viscosity and density. Higher-density memory foam reacts to body heat, allowing it to mold to a warm human body in a few minutes. A lower-density memory foam is pressure-sensitive and molds quickly to the shape of the body

In some embodiments, the core foam layer 36 of the pillow is fabricated from a polyurethane foam. In some embodiments, the outer foam layer 38 is fabricated from a polyurethane foam. In some embodiments, the core foam layer 36 of the pillow is fabricated from a viscoelastic foam. In some embodiments, the outer foam layer 38 is fabricated from a viscoelastic foam. In some embodiments, the core foam layer 36 and outer foam layer 38 are formed from polyurethane. In some embodiments, the core foam layer 36 and outer foam layer 38 are formed from a viscoelastic material. In some embodiments, the core foam layer 36 comprises gel foam. In some embodiments, the outer foam layer 38 comprises gel foam. In some embodiments, the core foam layer 36 and the outer foam layer 38 comprise gel foam.

According to exemplary embodiments of the present disclosure, the core foam layer 36 may comprise the majority of pillow 10, with an outer foam layer 38 of viscoelastic foam. In some embodiments, the outer foam layer 38 may be about 0.5 to about 1.0 inches in thickness, although alternative thicknesses may be employed such as, without limitation, about 0.6, about 0.7, about 0.75, about 0.8, or about 0.9 inches. It is further contemplated that the thickness of outer foam layer 38 may vary at different locations of anti-snore pillow 10. In some embodiments, the outer foam layer 38 may be thicker in the valley region as compared to the crests. The outer foam layer 38 may be on top of the pillow, as shown in FIG. 4. In some embodiments, the outer foam layer 38 may cover a portion or all of upper face 22. In some embodiments, the outer foam layer 38 may cover any or all of the sides (16, 18, 14, or 12) and/or base 20 of the pillow.

As shown in FIGS. 1-5, an anti-snore pillow 10 comprises a rear face 12, a front face 14, two side faces 16 and 18, a base 20 and an upper face 22. In some embodiments, base 20 may be substantially flat in design, thereby facilitating engagement with a sleep surface, e.g., a mattress. Rear face 12 may be vertical in orientation relative to base 20, but the disclosed pillow is not limited by or to such substantially vertical orientation. Side faces 16 and 18 may be vertical in orientation relative to base 20, although as with rear face 12, the present disclosure is not limited by or to such substantially vertical orientation.

Upper face 22 of anti-snore pillow 10 may include a first crest 34 and a second crest 30. A valley region 24 may be found between second crest 30 and first crest 34. In some embodiments, the valley region 24 is dimensioned to accommodate a user's head when the user's neck is positioned in substantial engagement with higher of the two crests 34. In some embodiments, the downwardly inclined surface 32 that extends from first crest 34 into valley region 24 is generally angularly oriented relative to base 20, such that pressure is relieved from the palate and uvula of the user. The angle of downwardly inclined surface 32 may be about 5° to about 20° relative to the horizontal, about 15° to about 20° relative to horizontal, and preferably about 18° relative to horizontal (i.e., base 20). In an embodiment of the present disclosure, the angle defined from the neck-supporting crest into the intermediate valley region of the disclosed pillow is about 15°-20° relative to horizontal. Specific examples of the angle defined from the neck-supporting crest to the intermediate valley region of the disclosed pillow may be about 15°, about 16°, about 17°, about 18°, about 19°, about 20°, or a range encompassed by any two of these values. In an embodiment, the surface of the pillow supporting the neck of a user is about 15°-20° relative to horizontal. In some embodiments, the angle of the surface of the pillow that supports the neck of the user may be about 15°, about 16°, about 17°, about 18°, about 19°, about 20°, or a range encompassed by any two of these values.

In the exemplary embodiment of FIGS. 1-5, valley region 24 extends from side-to-side of anti-snore pillow 10, i.e., from side face 16 to side face 18. However, alternative embodiments are contemplated wherein side walls may be provided that bound, in whole or in part, valley region 24. From the side view of FIG. 4, it is apparent that valley region 24 defines a substantially concave geometry such that sloping faces are defined to transition to crests 30, 34. In some embodiments, second crest 30 may be of equal (or substantially equal) height. In some embodiments, first crest 34 may be of greater height relative to base 20 as compared to second crest 30. In some embodiments, the first crest 34 may be about 30% to about 45% higher than the second crest 30. In some embodiments, the first crest 34 may be about 35% to about 40% higher than the second crest 30. In some embodiments, the first crest 34 may be about 38% higher than the second crest 30.

In some embodiments of the present disclosure, first crest 34 has a height of about 118.32 millimeters (mm) and second crest 30 has a height of about 85.5 mm. Other sizes are possible. For example, either or both of the crests may have heights ranging from about 3.5 to about 4 inches, about 4 to about 5 inches, about 3.5 to about 5 inches, about 3.5 to about 4 inches or other sizes. The overall width of the disclosed anti-snore pillow may vary widely. As shown in FIG. 2, in an exemplary embodiment, the pillow 10 may be about 487.3 mm (about 20 inches) wide from side face 16 to side face 18. The depth of the snore pillow 10 may also vary from implementation to implementation. In an exemplary embodiment, the distance from front face 14 to rear face 12 may be about 362.69 mm (about 15 inches) as shown in FIG. 1.

FIG. 6 describes an embodiment in which a combination of materials may be used for the base layer. As shown in FIG. 6, in some embodiments, a core foam layer 136 may include a central section 162 made of a first foam material and two side sections 152, 154 made of a second foam material. The base 164 also may be made of the second foam material. An outer foam layer 138 may be made of the second foam material or of a third foam material. Any of the first, second or third foam materials may be consistent with any of the foams described above in this disclosure, including, but not limited to, base foam, conventional polyurethane foam, viscoelastic foam, and/or gel-foam.

As shown in FIG. 6, exemplary dimensions of the various sections may include an overall depth (including base) of about 342.63 mm (about 13.5 inches). In some embodiments, the depth of the side sections 152 and 154, and central section 162 may be about 281.64 mm (about 11 inches). In some embodiments, the overall depth of the pillow may be from about 10 to about 15 inches, from about 5 to about 15 inches, from about 10 to about 17 inches, from about 5 to about 17 inches, about 10 inches, about 13 inches, about 15 inches, about 17 inches, or a range between any two of these values. In some embodiments, the depth of a pillow section may be from about 10 to about 15 inches, from about 5 to about 15 inches, from about 10 to about 17 inches, from about 5 to about 17 inches, about 10 inches, about 11 inches, about 13 inches, about 15 inches, about 17 inches, or a range between any two of these values. In some embodiments, the central section 162 may have a width that is about equal to that of the combined width of the side sections 152 and 154. For example, in the embodiment shown the central section 162 has a width of 254 mm (about 10 inches), while each side section (152, 154) has a width of 133.35 mm (about 5.25 inches). In some embodiments, each of the sections may be of equal width. In some embodiments, at least two of the sections may be of unequal width. In some embodiments, the width of a section may be from about 1 inch to about 15 inches, from about 5 to about 10 inches, from about 3 to about 15 inches, from about 5 to about 15 inches, from about 1 to about 10 inches, from about 3 to about 10 inches, or the like.
