Flexible packaging for compressed duct

Abstract

A container for a compressible article is disclosed, wherein the container includes first and second opposed sides having a first length, a first pair of flaps or edge attached to an end of the first and second opposed sides defining an end of the container, third and fourth opposed sides capable of having a second shorter length; and a second pair of flaps or edges attached to the third and fourth sides, the second pair of flaps having a fold line approximately aligned with the end of the container.

1 . A method of restraining a longitudinally compressed flexible duct, the method comprising:
 (a) disposing a flexible container about a longitudinally compressed flexible duct; and   (b) securing a permanent longitudinal strap about the flexible container to resist longitudinal expansion of the duct, the permanent longitudinal strap extending longitudinally about the flexible container and the longitudinally compressed flexible duct.   
     
     
         2 . The method of  claim 1 , wherein the permanent longitudinal strap extends from a first end of the flexible container to a second end of the flexible container. 
     
     
         3 . The method of  claim 1 , wherein the flexible container defines a substantially constant diameter from a first end of the flexible container to a second end of the flexible container. 
     
     
         4 . The method of  claim 1 , further including retracting a first portion of a temporary restraint prior to disposing the permanent longitudinal strap about the flexible container. 
     
     
         5 . The method of  claim 4 , further including holding the longitudinally compressed flexible duct in a compressed state with a second portion of the temporary restraint after retracting the first portion. 
     
     
         6 . The method of  claim 1 , wherein securing the permanent longitudinal strap about the flexible container includes one of heat fusing and stapling. 
     
     
         7 . The method of  claim 1 , wherein securing the permanent longitudinal strap about the flexible container includes securing the permanent longitudinal strap about the flexible container such that the longitudinally compressed flexible duct remains longitudinally compressed in the flexible container in the longitudinally compressed position. 
     
     
         8 . The method of  claim 1 , further comprising sealing the flexible container prior to securing the permanent longitudinal strap about the flexible container. 
     
     
         9 . A method of restraining a longitudinally compressed flexible duct, the method comprising:
 (a) securing a permanent longitudinal strap about a longitudinally compressed flexible duct to form a longitudinally compressed flexible duct assembly; and   (b) disposing the longitudinally compressed flexible duct assembly within a flexible container.   
     
     
         10 . The method of  claim 9 , wherein the permanent longitudinal strap precludes longitudinal expansion of the longitudinally compressed flexible duct. 
     
     
         11 . The method of  claim 9 , further comprising sealing the flexible container about the longitudinally compressed flexible duct assembly. 
     
     
         12 . The method of  claim 9 , wherein securing the permanent longitudinal strap about the longitudinally compressed flexible duct to form a longitudinally compressed flexible duct assembly includes securing the permanent longitudinal strap about the longitudinally compressed flexible duct to overlie a first end of the longitudinally compressed flexible duct and a second end of the longitudinally compressed flexible duct, the permanent longitudinal strap precluding longitudinal expansion of the longitudinally compressed flexible duct.
