Pre-assembled, self-contained, portable tank and method of using the tank for storing backflow fluids during hydrocarbon production operations. Tank is rapidly deployable and has a collapsible and refillable bladder for storing approximately 50,000 gallons or 1200 BBLS of fluids and a secondary containment with a holding capacity 120% of that of the bladder. When closed for transport, the tank is sufficiently compact and light to be movable with a light body pickup truck with an accompanying trailer over public roadways. After delivery to a site, a crew of two to five persons can set-up the tank for use within about 20 to 120 minutes.

Provided herein is a collapsible bulk-sized shipping box made of corrugated plastic. The rectangular box comprises four joined sidewalls, wherein left and right sidewalls are bisected by vertical fold lines allowing the sidewalls to be collapsed inwards. Bottom flaps also extend from the bottom of respective sidewalls and hinge inward about a fold line to provide a bottom side of the box when in use or fold flush with the sidewall when collapsed. The front wall of the box comprises a door flap that hinges inward and outward about a fold line. In addition, a door retaining puck attached to an outer surface of the front wall and configured to resist the door flap opening outward but deflect under application of sufficient force thereby allowing the door flap to open outward completely and provide access to the interior of the box.

The present disclosure provides for end walls for a freight container. The end walls include those for a rear wall and a front wall for the freight container. The rear wall includes rear corner posts each having a recess to receive a rear door hinge in the rear corner post and a corner fitting mounting block. The rear wall further includes corner fittings each having a receiving block, a sill member connected to a first rear corner posts by a member hinge, a header member connected to a second rear corner posts by a member hinge, a first rear wall door and a second rear wall door. The front wall includes front corner posts having gussets, anti-racking blocks, corner fittings with receiving blocks, a sill member, a header member and a front wall door.

The front wall includes front corner posts having gussets, anti-racking blocks, corner fittings with receiving blocks, a sill member, a header member and a front wall door.

One or more embodiments of the present disclosure provide a jointed member. The jointed member may include a first elongate section having a surface defining a first oblong opening, a second elongate section having a surface defining a second oblong opening, and a fastener passing through the first oblong opening and the second opening to connect the first elongate section and the second elongate section, where the first oblong opening and the second oblong opening move relative each other and the fastener as the jointed member transitions from a first predetermined state towards a second predetermined state.

A foldable container adjustable between an unfolded condition and a folded condition comprises a roof panel and an opposing base panel, a front panel and an opposing door panel, and a right side panel and an opposing left side panel. Each of the front panel and the door panel is hingedly connected to only the roof panel. The right side panel is offset from the left side panel. A right side roof skirt is associated with the right side panel and an opposing left side roof skirt is associated with the left side panel. A height of the right side roof skirt is disparate from a height of the left side roof skirt. A first compound beam and a second compound beam are provided on opposing ends of the base panel. A height of the first compound beam is disparate from a height of the second compound beam.

A connecting mechanism is used for a collapsible container, the collapsible container comprises a top cover and a chassis, four corners of the top cover are provided with a top corner piece which is connected with a top cover corner pillar, and four corners of the chassis are provided with a bottom corner piece which is connected with a chassis corner pillar, the connecting mechanism comprises a crook lug located at one of the top cover corner pillar and the chassis corner pillar; and a crook locking plate rotatablely provided at the outer end face of the other of the top cover corner pillar and the chassis corner pillar, the crook locking plate is provided with a crook part cooperating with the crook lug.

The technical objective of the present invention is to provide a foldable container enabling the entire height of a folded state thereof to be one fifth of the entire height of the state of being folded, such that the height of an international standard container can be satisfied even though empty containers are stacked in five stages. To this end, the hexagonal foldable container of the present invention comprises: an upper panel part and a lower panel part respectively forming the upper surface and lower surface thereof; a left panel part and a right panel part respectively forming the left surface and right surface thereof, and respectively folded; a front panel part and a rear panel part respectively forming the front surface and rear surface thereof; and a fixing bar provided at the outer surface of the rear panel part, and further includes first and second supporting members provided at the inner surface of the upper panel part so as to be movable forwards and backwards, wherein the front panel part and the rear panel part are respectively and pivotally provided at the first and second supporting members by means of upper hinge parts such that the respective outer surfaces thereof gradually face upwards.

A foldable container includes a pair of lateral plates foldably formed between a top plate and a bottom plate, where the lateral plates include an upper lateral plate and a lower lateral plate which are inwardly foldable by a hinge. The upper and lower lateral plates of the lateral plates respectively include upper molds and lower molds at corners on both sides thereof, and the upper and lower molds are mutually locked or unlocked by means of movement of a locking means. Accordingly, it is possible to allow a user to simply lock or unlock the folding of the container by controlling the locking means in the process of folding the container, and enabling the upper and lower molds to be automatically unfolded.
