Structured bag with structured closure

Abstract

A bag including a flexible bag body and having a structured closure including rigid ribs. The ribs are arranged in a spatial relationship to selectively stiffen and support the bag body in selected areas to define an overall shape of the bag, and to define at least one unsupported operative region of the flexible material that will be highly flexible due to the lack of overlying strengthening ribs, and act as the structured closure. The ribs may be spaced asymmetrically to define a preferred operative region for folding at an intended location. The bag body may define pockets or other internal organizer structure having an open top and the preferred operative region may be defined in vertical alignment with the open top of the organizer to provide easy access to the open top of the organizer. Bags may have any suitable shape and may include one or more structured closures.

1 . A structured bag for carrying items, the bag comprising:
 a bag body constructed of a flexible material, said bag body comprising at least one panel;   a plurality of elongated ribs constructed of a rigid material less flexible than said flexible material, at least a first pair of said plurality of ribs being joined to said at least one panel in a spaced relationship, said spaced relationship defining an operative region promoting folding, within said operative region, of said at least one panel between an open state and a closed state, to form a structured closure for said bag; and   a fastener secured to at least one of said first and second panels and operable to selectively fix said closure, and thus said bag, in the closed state.   
     
     
         2 . The structured bag of  claim 1 , wherein said panel defines a flap joined along one edge to a remainder of said bag body. 
     
     
         3 . The structured bag of  claim 1 , wherein said plurality of elongated ribs provides physical structure to said bag to prevent unsupported sagging of said flexible material and to cause said bag to assume a predefined shape in the closed state. 
     
     
         4 . The structured bag of  claim 1 , wherein each of said plurality of ribs extends continuously between ends of said at least one panel. 
     
     
         5 . The structured bag of  claim 1 , wherein each of said plurality of ribs is elongated in the horizontal direction, and wherein each of said operative regions is defined therebetween to be elongated in the horizontal direction. 
     
     
         6 . (canceled) 
     
     
         7 . The structured bag of  claim 1 , wherein bag body comprises at least two panels, each of said at least two panels comprising a respective plurality of elongated ribs constructed of said rigid material less flexible than said flexible material, at least a first pair of each respective plurality of elongated ribs being joined to a respective one of said at least two panels in said spaced relationship. 
     
     
         8 . The structured bag of  claim 1 , further comprising at least one pocket formed on said at least one panel, said at least one pocket have a respective open top 
     
     
         9 . (canceled) 
     
     
         10 . The structured bag of  claim 1 , further comprising:
 at least one divider panel fixed to a first portion of said bag body, said divider panel terminating in a free end selectively attachable to another portion of said bag body to define at least one compartment.   
     
     
         11 - 25 . (canceled) 
     
     
         26 . A structured bag for carrying items, the bag comprising:
 a bag body constructed of a flexible material, said bag body comprising at least one panel;   a plurality of elongated ribs constructed of a material less flexible than said flexible material, at least a first rib and a second rib of said plurality of elongated ribs being joined to said at least one of said panel in a first spaced relationship to provide support to said flexible bag body in areas adjacent said first and second ribs, and to thereby define therebetween, in a region between regions adjacent said first and second ribs a preferred operative region promoting folding of said at least one panel between an open state and a closed state, to form a closure for said bag; and   a fastener secured to said at least one of panel and operable to selectively fix said closure, and thus said bag, in the closed state.   
     
     
         27 . The structured bag of  claim 26 , wherein said panel defines a flap joined along one edge to a remainder of said bag body. 
     
     
         28 . The structured bag of  claim 26 , wherein each of said plurality of elongated ribs extends continuously between ends of said at least one panel. 
     
     
         29 . The structured bag of  claim 26 , wherein each of said plurality of elongated ribs is attached to an external surface of said at least one panel. 
     
     
         30 . The structured bag of  claim 26 , wherein each of said plurality of ribs is elongated in the horizontal direction, and wherein said operative region is defined therebetween to be elongated in the horizontal direction. 
     
     
         31 . The structured bag of  claim 26 , wherein bag body comprises at least two panels, each of said at least on additional panel, said at least one additional panel comprising an additional plurality of elongated ribs constructed of said rigid material less flexible than said flexible material, at least an additional pair of said additional plurality of elongated ribs being joined to said at least one additional panel in spaced relationship. 
     
     
         32 . The structured bag of  claim 26 , further comprising at least one pocket formed on said at least one panel, said at least one pocket have a respective open top. 
     
     
         33 . The structured bag of  claim 26 , further comprising:
 at least one pocket formed on said at least one panel, said at least one pocket have a respective open top; and   wherein said pair of said plurality of elongated ribs is disposed on said at least one panel to define said preferred operative region at a location corresponding to said open top of said at least one pocket.   
     
     
         34 . The structured bag of  claim 1 , further comprising:
 at least one divider panel fixed to a first portion of said bag body, said divider panel terminating in a free end selectively attachable to another portion of said bag body to define at least one compartment.
