Method of securing bulk flowable goods in paperboard container

Abstract

A paperboard container filled with flowable goods is secured with first, second and third sets of wrapping material wrapped about the exterior of the container. The wrapping material can be a pretensioned film. The first set is an open film, the second set is a cord and the third set is an open film. The cord extends from a bottom portion of the container to a top portion. The use of the wrapping material allows the container to have a reduced amount of paper content, thereby saving on material costs, and secures the container to a base member.

1 . A method of securing bulk flowable goods in a paperboard container, the container comprising side walls of paperboard, the walls enclosing an interior, comprising the steps of:
 a) loading the flowable goods into the interior of the container;   b) applying a first set of pretensioned wrapping material to an exterior of the container in a circumferential manner, the wrapping material comprising a film, the film of the first set being an open web;   c) applying a second set of the pretensioned wrapping material to the exterior of the container in a circumferential manner, the film of the second set being a cord, the cord being wrapped between a bottom portion of the container and a top portion of the container;   d) applying a third set of the pretensioned wrapping material to the exterior of the container in a circumferential manner, the film of the third set being an open web.   
     
     
         2 . The method of  claim 1 , further comprising the steps of:
 a) before loading the flowable goods into the interior of the container, placing the container on a base member;   b) the step of applying the first set of pretensioned wrapping material to an exterior of the container in a circumferential manner further comprises the step of applying the first set of pretensioned wrapping material to an exterior of the container and to the base member in a circumferential manner.   
     
     
         3 . The method of  claim 1 , wherein the steps of applying first, second and third sets of the pretensioned wrapping material further comprises the step of applying the first, second and third sets of wrapping material in a continuous length about the exterior of the container. 
     
     
         4 . The method of  claim 1 , further comprising the step of assembling the container before loading the flowable goods into the interior of the container, the step of assembling the container further comprising the step of folding the paperboard to form the side walls into an enclosure and joining ends of the sidewalls at a seam. 
     
     
         5 . The method of  claim 4 , where the step of joining the end walls at a seam further comprises the step of overlapping the ends of the side walls. 
     
     
         6 . The method of  claim 4 , wherein the step of assembling the container further comprises the step of folding bottom flaps to form a bottom wall. 
     
     
         7 . The method of  claim 1 , wherein the step of loading the flowable goods into the interior of the container further comprises the step of allowing the side walls of the container to bulge outwardly. 
     
     
         8 . The method of  claim 1 , wherein the steps of applying the first, second and third sets of the pretensioned wrapping material to an exterior of the container in a circumferential manner further comprises the step of applying the pretensioned wrapping material to the container by a film applicator and rotating one of the container or the film applicator relative to the other of the film applicator or container. 
     
     
         9 . The method of  claim 1 , wherein the steps of applying the first, second and third sets of the pretensioned wrapping material to an exterior of the container in a circumferential manner further comprises the step of applying the pretensioned wrapping material to the container by a film applicator, and pretensioning the wrapping material with the film applicator. 
     
     
         10 . The method of  claim 9 , further comprising the step of changing the film from the open web to the cord with the film applicator. 
     
     
         11 . The method of  claim 1 , wherein the step of applying a third set of the pretensioned wrapping material to the exterior of the container in a circumferential manner further comprises the step of overlaying the second set of wrapping material with the third set of wrapping material.
