although described as flat and straight stiffeners 24 26 could be implemented in other configurations e g angled curved etc furthermore although described as having one portion that is pre fastened to a section of the bag stiffener 24 could be provided as an add on device with an adhesive that could be attached to two or more adjacent sections accordingly stiffeners may be integrated into a bag during manufacture or provided as an add on device for later attachment still further although shown being attached to interior side sections of bag 10 stiffeners could be implemented to attach to exterior side sections finally it is also understood that the particular shape dimensions and material used to implement a stiffener can vary depending upon the particular amount of stiffness required fig3 depicts an isometric view of a partially opened bag 40 having stiffeners 44 46 in an un deployed position similar to that shown in fig1 bag 40 includes two fold lines 50 52 which when extended provide access to opening 42 in this embodiment stiffeners 44 46 are pre fastened to side sections 54 and 56 an adhesive 48 e g with a removable cover can be seen on the back side of fastener 46 stiffener 44 likewise includes an adhesive but cannot be seen in this view note that in this embodiment stiffeners 44 46 are pre fastened to side sections 54 56 in a kitty corner manner such that the un fastened portions extend in opposite directions however it is understood that the invention is not limited to such an implementation for instance stiffener 46 could be pre fastened to side section 58 instead of side section 56 fig4 depicts bag.
