Sleep mask products
The present disclosure relates to sleep mask products and methods of making same. Disclosed are sleep mask products comprising: a mask body and a mask strap; wherein the mask strap has a first attachment point to a first lateral edge of the mask body and a second attachment point to a second lateral edge of the mask body; and wherein the mask body comprises a first fabric layer; a second fabric layer; a first foam layer; and a second foam layer. The second fabric inner surface comprises a phase change material thereon. The second foam layer second surface contacts the phase change material, the second fabric inner surface, or a combination thereof. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

wherein the second fabric inner surface comprises a phase change material thereon;
wherein the second foam layer second surface contacts the phase change material, the second fabric inner surface, or a combination thereof;
wherein the mask body has a first eye masking area, a second eye masking area, and a nose area;
wherein the first eye masking area is configured to cover a first eye of the human subject and mitigate passage of light to the first eye;
wherein the second eye masking area is configured to cover a second eye of the human subject and mitigate passage of light to the second eye;
wherein the mask body has a mask body upper edge that is configured to be in contact with a portion of the brow or forehead when wore by the human subject;
wherein the nose area is configured to fit over a nose of the human subject;
wherein a brow fitting component is positioned parallel to the mask body upper edge and between the first foam layer second surface and the second foam layer first surface; and
wherein nose fitting component is positioned parallel to the nose area edge and between the first foam layer second surface and the second foam layer first surface; wherein the phase change coating is present on the second fabric layer inner surface in an amount of from about 25 grams dry weight per square meter to about 100 grams dry weigh per square meter; wherein the first foam layer is a closed cell foam material and wherein the first foam layer comprises a high-density polyurethane foam material; and wherein the first foam layer has a density of greater than or equal to about 1.5 lbs/ft3.
2 . The sleep mask product of claim 1 , wherein the phase change material forms a phase change coating on the second fabric layer inner surface.
3 . The sleep mask product of claim 2 , wherein the phase change coating forms a discontinuous patterned coating on the second fabric layer inner surface.
4 . The sleep mask product of claim 1 , wherein the first foam layer comprises at least one region having an open cell foam material, closed cell foam material, or semi-closed cell foam material and at least one other region comprising a different cell foam material.
5 . The sleep mask product of claim 1 , wherein the second foam layer comprises at least one region having an open cell foam material, closed cell foam material, or semi-closed cell foam material and at least one other region comprising a different cell foam material.
6 . The sleep mask product of claim 1 , wherein the second foam layer is a closed cell foam material.
7 . The sleep mask product claim 6 , wherein the second foam layer is a high-density polyurethane foam material; and wherein and wherein the first foam layer has a density of greater than or equal to about 1.5 lbs/ft 3 .
8 . The sleep mask product of claim 1 , wherein the first fabric outer surface comprises a decorative image thereon.
9 . The sleep mask product of claim 8 , wherein the decorative image is printed on the first fabric outer surface.
10 . The sleep mask product of claim 8 , wherein the decorative image is embossed on the first fabric outer surface.
11 . The sleep mask product of claim 1 , wherein the brow fitting component comprises a material that is capable of being deformed by hand to change its shape and retaining such changed shape until again deformed by hand; and wherein the brow fitting component is of such length and configuration as to conform to a portion of the brow or forehead and generally define an outer periphery of the mask body positioned proximal to or over the brow, eyebrows, or forehead of the human subject.
12 . The sleep mask product of claim 11 , wherein the brow fitting component is a malleable wire comprising copper, aluminum, steel, brass, or combinations thereof.
13 . The sleep mask product of claim 1 , wherein the nose fitting component comprises a material that is capable of being deformed by hand to change its shape and retaining such changed shape until again deformed by hand; and wherein the nose fitting component is of such length and configuration as to conform to a portion of the nose and generally define an outer periphery of the nose area positioned proximal to or over the nose of the human subject.
