The present disclosure relates to a blow-molded, rigid collapsible container that can be suitable for storage and dispensing systems of practically any size. The rigid collapsible container may be a stand-alone container. The container may be blow-molded as a unitary piece that may include folds or pre-folds that allows the container to collapse into a relatively flat position. In an expanded state, the container may have a generally trapezoidal prism shape.

1. A blow molded container comprising: a plurality of predetermined fold lines in one or more container walls, the plurality of predetermined fold lines allowing the container walls to flex along the fold lines to an at least partially collapsed state and unfold along the fold lines to a shape of predetermined volume; anda locking mechanism for locking, at least temporarily, the container walls in the unfolded state, the locking mechanism comprising a base portion comprising a living hinge and a slide portion operably attached thereto, the slide portion slidable along the base portion from an unlocked position, permitting the base portion to flex at the living hinge, to a locked position which substantially prevents the base portion from flexing at the living hinge. 2. The container of claim 1, wherein the container walls comprise at least one of polyethylene terephthalate (PET), polyethylene naphthalate (PEN), poly(butylene 2,6-naphthalate) (PBN), polyethylene (PE), linear low-density polyethylene (LLDPE), low-density polyethylene (LDPE), medium-density polyethylene (MDPE), high-density polyethylene (HDPE), and polypropylene (PP). 3. The container of claim 1, wherein two opposing side walls comprise predetermined fold lines that upon collapse of the container, cause the opposing side walls to fold inward. 4. The container of claim 3, further comprising a top wall, wherein in an unfolded state, has at least a portion that is configured in an incline slope relative the bottom wall of the container. 5. The container of claim 4, further comprising a fitment port positioned on the inclined slope of the top wall. 6. A blow molded container comprising: a plurality of panel walls abutting one another along predetermined fold lines, the plurality of panel walls substantially forming a container of nearly cylindrical shape with nearly domed ends;a fitment port positioned at the top of the container and aligned with a central axis of the container; anda locking mechanism for locking, at least temporarily, the container in the unfolded state, the locking mechanism comprising a substantially rigid base cup removably attachable to the panel walls, the rigidity of the base cup substantially preventing the panel walls from significantly collapsing along the predetermined fold lines;wherein the plurality of predetermined fold lines permit the container walls to flex along the fold lines to an at least partially collapsed state and unfold along the fold lines into the nearly cylindrical shape with nearly domed ends, and wherein the predetermined fold lines run generally vertically along the container. 7. The container of claim 6, wherein the predetermined fold lines alternate between flexing convexly and concavely with respect to the central axis of the container, thereby permitting the container to collapse axially. 8. A blow molded container comprising: a plurality of predetermined fold lines in one or more container walls, the plurality of predetermined fold lines allowing the container walls to flex along the fold lines to an at least partially collapsed state and unfold along the fold lines to a shape of predetermined volume; anda locking mechanism for locking, at least temporarily, the container walls in the unfolded state, the locking mechanism comprising one or more tabs on the container and a substantially rigid brace insertable into the tabs such that the brace supports the container in its unfolded state and substantially prevents the container from collapsing significantly. 9. The container of claim 8, wherein the container walls comprise at least one of polyethylene terephthalate (PET), polyethylene naphthalate (PEN), poly(butylene 2,6-naphthalate) (PBN), polyethylene (PE), linear low-density polyethylene (LLDPE), low-density polyethylene (LDPE), medium-density polyethylene (MDPE), high-density polyethylene (HDPE), and polypropylene (PP). 10. The container of claim 8, wherein two opposing side walls comprise predetermined fold lines that upon collapse of the container, cause the opposing side walls to fold inward. 11. The container of claim 10, further comprising a top wall, wherein in an unfolded state, has at least a portion that is configured in an incline slope relative the bottom wall of the container. 12. The container of claim 11, further comprising a fitment port positioned on the inclined slope of the top wall. 13. A blow molded container comprising: a plurality of predetermined fold lines in one or more container walls, the plurality of predetermined fold lines allowing the container walls to flex along the fold lines to an at least partially collapsed state and unfold along the fold lines to a shape of predetermined volume; anda locking mechanism for locking, at least temporarily, the container walls in the unfolded state, the locking mechanism comprising a rotating disk located along at least one pre-fold, the disk having at least one substantially rigid area and at least one weakened area, wherein when the rotating disk is rotated such that the at least one substantially rigid area is aligned with the at least one pre-fold, the disk substantially prevents the at least one pre-fold from flexing significantly at the location of the disk. 14. The container of claim 11, wherein the container walls comprise at least one of polyethylene terephthalate (PET), polyethylene naphthalate (PEN), poly(butylene 2,6-naphthalate) (PBN), polyethylene (PE), linear low-density polyethylene (LLDPE), low-density polyethylene (LDPE), medium-density polyethylene (MDPE), high-density polyethylene (HDPE), and polypropylene (PP). 15. The container of claim 11, wherein two opposing side walls comprise predetermined fold lines that upon collapse of the container, cause the opposing side walls to fold inward. 16. The container of claim 15, further comprising a top wall, wherein in an unfolded state, has at least a portion that is configured in an incline slope relative the bottom wall of the container. 17. The container of claim 16, further comprising a fitment port positioned on the inclined slope of the top wall.
