Pillow stuffed with latex foam crumbs

Abstract

A method of manufacturing a pillow, comprising the steps of granulating pieces of latex foam to produce a variety of sizes of latex foam crumbs; passing the crumbs through a screen to generally exclude most latex foam crumbs which are greater than a predetermined nominal diameter; filling a pillow casing with the screened crumbs; and sealing the casing shut to capture the latex foam crumbs. The screen optimally has apertures approximately ⅜ inch (9.5 mm) in diameter to produce a pillow comprising a casing filled with latex foam crumbs where the latex foam crumbs are in a variety of sizes, generally not exceeding about 1 inch (25.4 mm) in nominal diameter.

1 . A pillow comprising a casing filled with latex foam crumbs.  
     
     
         2 . A pillow as recited in  claim 1 , wherein said latex foam crumbs are in a variety of sizes, generally not exceeding about 1 inch (25.4 mm) in nominal diameter.  
     
     
         3 . A pillow as recited in  claim 1 , wherein the weight of latex foam crumbs for a standard-sized pillow having a casing approximately 26 cm×36.5 cm when empty and flat is in the range of 2.0-3.3 lbs (0.91-1.50 kg).  
     
     
         4 . A pillow as recited in  claim 3 , wherein the weight of latex foam crumbs is approximately 2.7 lbs (1.23 kg).  
     
     
         5 . A pillow as recited in  claim 1 , wherein the weight of latex foam crumbs for a queen-sized pillow having a casing approximately 30 cm×36.5 cm when empty and flat is in the range of 2.5-3.6 lbs (1.13-1.63 kg).  
     
     
         6 . A pillow as recited in  claim 5 , wherein the weight of latex foam crumbs is approximately 3.1 lbs (1.41 kg).  
     
     
         7 . A pillow as recited in  claim 1 , wherein the weight of latex foam crumbs for a king-sized pillow having a casing approximately 35 cm×36.5 cm when empty and flat is in the range of 3.0-4.5 lbs (1.36-2.04 kg).  
     
     
         8 . A pillow as recited in  claim 7 , wherein the weight of latex foam crumbs is approximately 3.7 lbs (1.68 kg).  
     
     
         9 . A method of manufacturing a pillow, comprising the steps of: 
 granulating pieces of latex foam to produce a variety of sizes of latex foam crumbs;    passing said latex foam crumbs through a screen to generally exclude most latex foam crumbs which are greater than a predetermined nominal diameter;    filling a pillow casing with said screened latex foam crumbs; and    sealing said casing shut to capture said latex foam crumbs.    
     
     
         10 . A method as recited in  claim 9 , wherein said screen has apertures approximately ⅜ inch (9.5 mm) in diameter to let through said screen only latex foam crumbs generally not exceeding about 1 inch (25.4 mm) in nominal diameter.  
     
     
         11 . A method as recited in  claim 9 , wherein said sealing step is performed by sewing said casing shut.
