Convex pillow configuration

Abstract

The pillow includes at least two substantially identical pillow shell layers secured to each other around the peripheries thereof. Each layer has corner configurations defined by approximately straight, inwardly directed tapered end portions of adjacent edges, which meet at corner points, wherein the angle between the meeting end portions of adjacent edges is in the range of 120°-140°.

1 . A pillow having a modified corner configuration, comprising:
 at least two pillow shell layers, each layer having approximately the same configuration, joined together around the peripheries thereof or to an intermediate gusset portion, wherein the corners of each layer are defined by a meeting of end portions of two adjacent edges, the meeting end portions tapering inwardly from the remainder of their respective edges to a point to define a corner, wherein the angle between the two meeting end portions is greater than 90°; and   filling between the two pillow shell layers   
     
     
         2 . The pillow of  claim 1 , wherein each end portion is approximately straight over most of the length thereof. 
     
     
         3 . The pillow of  claim 1 , wherein said angle is within the range of 120-140°. 
     
     
         4 . The pillow of  claim 1 , wherein the end portions begin approximately five inches from the ends of the edges of the pillow. 
     
     
         5 . The pillow of  claim 1 , wherein each corner point meeting of edge end portions is located approximately one-half inch inwardly from a straight-line continuation of the edges of the pillow. 
     
     
         6 . The pillow of  claim 1 , including a gusset member positioned between and sewn to the two pillow shell layers, wherein the gusset member follows the edge configuration of the pillow shell layers. 
     
     
         7 . The pillow of  claim 1 , wherein the filling between the two pillow shell layers is sufficient that the filled pillow has edges which are substantially straight and corners which appear completely filled. 
     
     
         8 . The pillow of  claim 6 , including top and bottom layers, approximately the same size and configuration as the pillow shell layers, sewn to the pillow shell layers and the gusset member, thereby defining three separate pillow chambers for the pillow, one chamber between the top layer and an upper pillow shell layer, another chamber between the upper pillow shell layer and a lower pillow shell layer, and still another chamber between the lower pillow shell layer and the bottom layer. 
     
     
         9 . The pillow of  claim 8 , including filling in the first, second and third chambers.
