Weighted blanket

Abstract

A weighted blanket includes an inner liner that is filled with weighted filler material and closed to limit movement of the weighted material within the inner liner. In some embodiments, the inner liner is securely sewn within an outer liner to prevent movement of the inner liner within the outer liner, thereby preventing the inner liner from becoming detached from the outer liner.

What is claimed is: 
     
         1 . A blanket comprising:
 a weighted material;   an inner liner disposed surrounding the weighted material and closed to limit movement of the weighted material within the inner liner; and   an outer liner substantially surrounding and attached to the inner liner.   
     
     
         2 . The blanket of  claim 1 , wherein the weighted material comprises a weighted sphere. 
     
     
         3 . The blanket of  claim 2 , wherein the weighted sphere is formed from a material selected from the group consisting of metal, plastic, glass, wood, and stone. 
     
     
         4 . The blanket of  claim 1 , wherein the weighted material comprises a weighted tube. 
     
     
         5 . The blanket of  claim 4 , wherein the weighted tube has a length and sewn at intervals along its length to form a plurality of compartments into which a weighted filling is introduced, and wherein the weighted tube is sewn to the outer liner. 
     
     
         6 . The blanket of  claim 5 , wherein the weighted filling comprises a plurality of beads that are substantially inaudible when brought into contact with one another. 
     
     
         7 . The blanket of  claim 5 , wherein the weighted filling comprises a plurality of beads that, when brought into contact with one another, produce audible sound. 
     
     
         8 . The blanket of  claim 5 , wherein the weighted filling introduced into different compartments have different weights. 
     
     
         9 . The blanket of  claim 1 , wherein the weighted material comprises a weighted pouch. 
     
     
         10 . A blanket comprising:
 a liner having a plurality of pockets formed therein; and   a plurality of weighted objects, each weighted object disposed within a pocket formed in the inner liner and positioned to apply pressure to a human body when the blanket is in use.   
     
     
         11 . The blanket of  claim 10 , wherein the weighted objects are substantially spherical. 
     
     
         12 . The blanket of  claim 10 , wherein the weighted objects are formed from a material selected from the group consisting of metal, plastic, glass, wood, and stone. 
     
     
         13 . The blanket of  claim 10 , wherein the liner is formed from a material selected from the group consisting of olefin, plastic, and TEFLON® brand polytetrafluoroethylene. 
     
     
         14 . A method of manufacturing a blanket, the method comprising:
 providing a plurality of inner liners each having a first end portion, a second end portion located distally from the first end portion, and a length;   for each inner liner, closing the first end portion to form a compartment;   for each inner liner, introducing a weighted filler material into the compartment;   for each inner liner, closing the second end portion to secure the weighted filler material within the compartment, thereby forming a tube;   providing an outer liner surrounding the tubes formed by the inner liners; and   attaching the tubes formed by the inner liners within the outer liner.   
     
     
         15 . The method of  claim 14 , further comprising dividing the weighted filler material into a plurality of portions of weighted filler material and, for each inner liner, sewing the each inner liner at intervals along its length to form a plurality of compartments and introducing a portion of the weighted filler material into each of the plurality of compartments. 
     
     
         16 . The method of  claim 15 , wherein the portions of weighted filler material introduced into different compartments have different weights. 
     
     
         17 . The method of  claim 14 , wherein the weighted filler material comprises a plurality of beads that are substantially inaudible when brought into contact with one another. 
     
     
         18 . The method of  claim 14 , wherein the weighted filler material comprises a plurality of beads that, when brought into contact with one another, produce audible sound. 
     
     
         19 . The method of  claim 14 , further comprising sewing the outer liner at intervals to form a plurality of partitions to receive the tubes formed by the inner liners. 
     
     
         20 . The method of  claim 14 , further comprising, for each inner liner, providing unfilled portions at the first and second end portions, and wherein attaching the tubes formed by the inner liners within the outer liner comprises sewing the unfilled portions to the outer liner.
