Folding container

Abstract

A folding container includes: a bottom frame panel having a bottom panel, a left support, a right support, a front support, and a rear support; a left side frame panel and a right side frame panel each having a first side panel, a first upper outer frame, a first lower outer frame, and first side outer frames; and a front frame panel and a rear frame panel each having a second side panel, a second upper outer frame, a second lower outer frame, and second side outer frames.

What is claimed is: 
     
         1 . A folding container, comprising:
 a bottom frame panel having: a bottom panel; a left support and a right support erected at left and right edges of the bottom panel, respectively, and each having a plurality of side frame panel-coupling portions at upper edges; and a front support and a rear support erected at front and rear edges, respectively, and each having a plurality of front/rear frame panel-coupling portions;   a left side frame panel and a right side frame panel each having: a first side panel; a first upper outer frame; a first lower outer frame having a plurality of first support-coupling portions protruding downward and rotatably fitted in the side frame panel-coupling portions; and first side outer frames each having a plurality of frame panel-coupling projections, the frames being disposed at four edges of the first side panel; and   a front frame panel and a rear frame panel each having: a second side panel; a second upper outer frame; a second lower outer frame having a plurality of support-coupling portions protruding downward and rotatably fitted in the front/rear frame panel-coupling portions; and second side outer frames each having a plurality of frame panel-coupling holes for fitting the frame panel-coupling projections, the frames being disposed at four edges of the second side panel.   
     
     
         2 . The folding container of  claim 1 , wherein the side frame panel-coupling portion has a pair of first horizontal coupling projection-holding steps, a pair of first vertical coupling projection-holding steps, and a pair of coupling projection-holding grooves,
 the front/rear frame panel-coupling portion has a pair of second horizontal coupling projection-holding steps, a pair of second vertical coupling projection-holding steps, and a pair of second coupling portion-holding grooves,   the first support-coupling portion has a pair of first support-coupling projections, and   the second support-coupling portion has a pair of second support-coupling projections.   
     
     
         3 . The folding container of  claim 2 , wherein the front/rear frame panel-coupling portion further has a support-fixing projection hole and a coupling portion-supporting projection, and
 the second support-coupling portion has a support-fixing projection fitted in the support-fixing projection hole and a coupling portion-supporting projection hole for fitting the coupling portion-supporting projection.   
     
     
         4 . The folding container of  claim 1 , wherein the front support and the rear support each further have a plurality of front/rear frame panel-guiding/supporting portions on an upper edge, and
 the front frame panel and the rear frame panel each have guiding/supporting projections that are erected in the front/rear frame panel-guiding/supporting portions by rotating.   
     
     
         5 . The folding container of  claim 4 , wherein the front/rear frame panel-guiding/supporting portions each have a guiding/supporting projection groove, a pair of side extensions, and a guide slope, and
 the guiding-supporting projection has a pair of side extensions extending outward.   
     
     
         6 . The folding container of  claim 1 , wherein the first upper outer frame has two frame panel-fixing member seats formed in the horizontal direction therein to correspond to each other, and
 frame panel-fixing members for fixing the left side and right side frame panels to the front and rear frame panels.   
     
     
         7 . The folding container of  claim 6 , wherein the frame panel-fixing member has a fixing bar, a handle formed at a first end of the fixing bar, elastic portions formed ahead of the handle, a guide formed ahead of the elastic portions, a stopper formed ahead of the guide, and a fixing end at a second end of the fixing bar,
 the first side outer frames each have a fixing-end hole,   the frame panel-fixing member seat has frame panel-fixing member grooves, two ribs having a fixing-bar hole, a handle holder, and a stopper hole, and   the second side outer frame has fixing-end holes for fitting the fixing ends.
