Collapsible portable reusable container

A collapsible portable reusable container for solids, liquids or a combination of both but not limited to stated, formed from an integral flat blank of sheet material, said blank comprising:

• (a) a polygon bottom panel with a center fold at half the length of bottom for folding collapsed container in half, having oppositely disposed end panels and oppositely disposed adjacent side panels integrally connected thereto along a plurality of spaced end fold lines intersecting a second plurality of spaced side fold lines respectively,
• (1) each of said fold lines intersecting each of said oppositely disposed fold lines at angles dependent on plurality of sides,
• (2) said fold lines defining the edges of said polygon bottom panel, the bottom and end edges of each end panel and the bottom and end edges of each adjacent side panel respectively,
• (3) said fold line bisecting length of bottom panel for fold and to facilitate portability
• (b) tension hinge means existent between and connecting each end edge of said end panels and the next adjacent end edge of said oppositely disposed adjacent side panels, consisting of a gusset secured to said end panel and a tension fold opposite the gusset on said adjacent side panel
• (1) each gusset consisting of a first substantially triangular-like shaped section having one edge outwardly connected to said end edge of said end panel and a second substantially triangular like shaped section having one edge outwardly connected to said end edge of said adjacent side panel
• (2) said first and second sections each having a common second edge outwardly connecting each other along a fold line angularly directed to bisect said right angle existent between said intersecting fold lines defining said gusset outwardly connected end edges,
• (3) said gusset is foldably secured to said end panel with an oppositely disposed tension fold line on said adjacent side panel
• (4) a tension fold consisting of an oppositely disposed fold line angularly directed to bisect said right angle existent between said intersecting fold lines of said gusset on said adjacent side panel.
• (c) said blank being foldable into a portable erect container by folding said end panels upwardly and onto the inner surface of said bottom panel and by folding said adjacent side panels upwardly and onto the outer surface of said bottom panels with each of said gussets being folded simultaneously outward with said panels positioned between the inner surface of said end panels and the inner surface of said adjacent side panels and having said first triangular-like section of said gusset secured to outer surface of said end panel with an outwardly folded tension fold angularly directed to bisect said right angle between intersecting fold lines on said adjacent side panels
• (d) said erect portable reusable container is folded into a collapsed portable container by folding inwardly at tension fold on side panel while simultaneously folding said side panels inwardly upon said bottom panel causing end panels to fold inwardly upon the folded side panel then folding in half at center fold of bottom panel by bringing end panels inwardly together and secured to facilitate portability
• (e) the said folded portable reusable container is made erect into a freestanding container by releasing secured end panels and pulling downwards at center fold to make said bottom panel flat then pulling said side panels upward outward and downward outwardly engaging the tension hinge into bringing the container into an open freestanding position.
