Sleeping pillows and methods of making sleeping pillows having double inserts
View Patent ↗A method of making a pillow includes obtaining a first pillow half having an outer surface and an inner surface having a first cavity formed therein, filling the first cavity with a first filler material, obtaining a second pillow half having an outer surface and an inner surface having a second cavity formed therein, and filling the second cavity with a second filler material. The method includes, after the filling steps, juxtaposing the inner surface of the first pillow half with the inner surface of the second pillow half and joining the first and second pillow halves together to form a pillow.
1. A method of making a pillow comprising:
obtaining a first pillow half having an outer surface and an inner surface having a first cavity formed therein;
filling said first cavity with a first filler material;
obtaining a second pillow half having an outer surface and an inner surface having a second cavity formed therein;
filling said second cavity with a second filler material;
after the filling steps, juxtaposing said inner surface of said first pillow half with said inner surface of said second pillow half and joining said first and second pillow halves together to form a pillow;
wherein the filling said first cavity with a first filler material step comprises depositing a flowable cooling gel into said first cavity and curing said cooling gel to provide a cured cooling gel layer having an outer surface that is parallel to and aligned with said inner surface of said first pillow half.
2. The method as claimed in claim 1 , wherein said first and second pillow halves comprise foam.
3. The method as claimed in claim 2 , wherein at least one of said first and second pillow halves comprises a cooling gel.
4. The method as claimed in claim 1 , wherein said first and second filler materials are selected from the group consisting cooling gel, cooling gel layers, shredded foam, chopped foam, shredded latex, chopped latex, fibers, polyester fibers, molded or cut foam layers, molded or cut foam cores, molded or cut memory foam layers, molded or cut memory foam cores, molded or cut polyurethane foam layers, and molded or cut polyurethane foam cores.
5. The method as claimed in claim 1 , wherein the joining step comprises adhering said inner surfaces of said first and second pillow halves together.
6. The method as claimed in claim 1 , wherein said joining step comprises adhering an outer surface of said first filler material to an outer surface of said second filler material.
7. The method as claimed in claim 1 , wherein the filling said second cavity step comprises depositing a flowable cooling gel into said second cavity and curing said cooling gel to provide a second cured cooling gel layer having an outer surface that is parallel to and aligned with said inner surface of said second pillow half.
8. The method as claimed in claim 7 , further comprising adhering said inner surface of said first pillow half to said inner surface of said second pillow half.
9. The method as claimed in claim 8 , further comprising adhering said outer surface of said first cured cooling gel layer to said outer surface of said second cured cooling gel layer.
10. A pillow comprising:
a first memory foam pillow half having an outer surface and an inner surface having a first cavity formed therein;
a first filler material disposed within said first cavity, said first filler material comprising a first cooling gel layer having an outer surface that is parallel to and aligned with said inner surface of said first memory foam pillow half;
a second memory foam pillow half having an outer surface and an inner surface having a second cavity formed therein;
a second filler material within said second cavity, said second filler material comprising a second cooling gel layer having an outer surface that is parallel to and aligned with said inner surface of said second memory foam pillow half, wherein said inner surfaces of said first and second memory foam pillow halves are joined together to form a pillow.
11. The pillow as claimed in claim 10 , wherein said inner surfaces of said first and second memory foam pillow halves are adhered together.
12. The pillow as claimed in claim 11 , wherein said outer surfaces of said first and second cooling gel layers are adhered together.
13. The pillow as claimed in claim 12 , further comprising an adhesive that joins said first and second pillow halves together.
14. The pillow as claimed in claim 12 , wherein said first and second filler materials comprise one of cooling gel, chopped foam, chopped latex and/or fibrous material.
15. The pillow as claimed in claim 14 , wherein said first and second filler materials may further comprise phase change material.
