Method of packaging resiliently compressible articles

Abstract

A method of packaging a resiliently compressible article comprises the steps of inserting the article into a tube of deformable material such that excess material is provided at the ends of the tube. A first end of the tube is then sealed closed. Air is then evacuated from the tube through the second end thereby deforming the tube around the article and causing the article to compress. While a vacuum is maintained in the tube, the second end of the tube is sealed closed. A containment sleeve is fitted over the sealed tube to maintain the article in a compressed state. When the article is unpackaged, the containment sleeve is severed and the tube is allowed to expand in a gradual controlled fashion by the bleeding of air back into the tube.

What is claimed is: 
     
       1. A method of packaging a mattress assembly constructed of coil springs wherein each spring is contained within an individual pocket of fabric, comprising the steps of: providing a tube of deformable material, said tube having a predetermined length;   inserting a mattress assembly constructed of pocketed coil springs into said tube, said mattress assembly having a length which is less than the length of said tube, thereby defining first and second tube ends of excess material;   sealing a first end of said tube;   evacuating air from said tube through said second end thereby deforming said tube around said mattress assembly and causing said mattress assembly to compress;   . .sealing said second end of said tube after evacuating said tube to a predetermined state;.!.   inserting said evacuated tube into a containment sleeve which is dimensioned and configured to retain said compressed mattress assembly in a compressed state for shipment;   removing said evacuated tube from said containment sleeve; . .and   puncturing said evacuated tube to allow.!. .Iadd.whereby .Iaddend.said mattress assembly in said tube . .to.!. gradually . .return.!. .Iadd.returns .Iaddend.to an uncompressed state.   
     
     
       2. The method of claim 1 wherein said first end of said tube is sealed after gathering the excess material of said first end. 
     
     
       3. The method of claim 1 wherein said evacuating step includes gathering said second end of said tube around a vacuum, evacuating means. 
     
     
       4. The method of claim 1 wherein said tube is cut to said predetermined length from a continuous length of tube material. .Iadd. 
     
     
       5.  A method of packaging a mattress assembly constructed of coil springs wherein each spring is contained within an individual pocket of fabric, comprising the steps of: providing a tube of deformable material, said tube having a predetermined length;   inserting a mattress assembly constructed of pocketed coil springs into said tube, said mattress assembly having a length which is less than the length of said tube, thereby defining first and second tube ends of excess material;   sealing a first end of said tube;   evacuating air from said tube through said second end thereby deforming said tube around said mattress assembly and causing said mattress assembly to compress;   sealing said second end of said tube after evacuating said tube to a predetermined state;   inserting said evacuated tube into a containment sleeve which is dimensioned and configured to retain said compressed mattress assembly in a compressed state for shipment;   removing said evacuated tube from said containment sleeve; and   allowing said mattress assembly in said tube to gradually return to an uncompressed state..Iaddend..Iadd.   
     
     
       6.  A method of packaging a mattress assembly constructed of coil springs wherein each spring is contained within an individual pocket of fabric, comprising the steps of: providing a tube of deformable material, said tube having a predetermined length;   inserting a mattress assembly constructed of pocketed coil springs into said tube, said mattress assembly having a length which is less than the length of said tube, thereby defining first and second tube ends of excess material;   sealing a first end of said tube;   evacuating air from said tube through said second end thereby deforming said tube around said mattress assembly and causing said mattress assembly to compress;   sealing said second end of said tube while said tube is being evacuated to a predetermined state;   inserting said evacuated tube into a containment sleeve which is dimensioned and configured to retain said compressed mattress assembly in a compressed state for shipment;   removing said evacuated tube from said containment sleeve; and   allowing said mattress assembly in said tube to gradually return to an uncompressed state..Iaddend..Iadd.   
     
     
       7.  A method of packaging a mattress assembly constructed of coil springs wherein each spring is contained within an individual pocket of fabric, comprising the steps of: providing a tube of deformable material, said tube having a predetermined length;   inserting a mattress assembly constructed of pocketed coil springs into said tube, said mattress assembly having a length which is less than the length of said tube, thereby defining first and second tube ends of excess material;   sealing a first end of said tube;   evacuating air from said tube through said second end thereby deforming said tube around said mattress assembly and causing said mattress assembly to compress;   inserting said evacuated tube into a containment sleeve which is dimensioned and configured to retain said compressed mattress assembly in a compressed state for shipment;   removing said evacuated tube from said containment sleeve; and   allowing said mattress assembly in said tube to gradually return to an uncompressed state; and   said evacuated tube is punctured to allow said mattress assembly in said tube to gradually return to said uncompressed state..Iaddend..Iadd.   
     
     
       8.  A method of packaging a mattress assembly constructed of coil springs wherein each spring is contained within an individual pocket of fabric, comprising the steps of: providing a tube of deformable material, said tube having a predetermined length;   inserting a mattress assembly constructed of pocketed coil springs into said tube, said mattress assembly having a length which is less than the length of said tube, thereby defining first and second tube ends of excess material;   sealing a first end of said tube;   evacuating air from said tube through said second end thereby deforming said tube around said mattress assembly and causing said mattress assembly to compress;   inserting said evacuated tube into a containment sleeve which is dimensioned and configured to retain said compressed mattress assembly in a compressed state for shipment;   removing said evacuated tube from said containment sleeve;   allowing said mattress assembly in said tube to gradually return to an uncompressed state; and   said containment sleeve is severed to allow said mattress assembly in said tube to gradually return to said uncompressed state..Iaddend..Iadd.   
     
     
       9.  The method of claim 1 wherein said evacuated tube inserted into said containment sleeve is allowed to expand within said containment sleeve..Iaddend.
