Large format polymeric containers formed by injection molding include a main body having internal surfaces of high density and smoothness that define the internal space. The large format containers can include external features such as reinforcement ribs that are formed integrally with the container body, the reinforcement ribs having greater thicknesses than other portions of the walls of the container. The internal surfaces can include rounded corners and sloping towards a center of the container. Methods of manufacturing the large format polymeric containers include forming the polymeric main body using injection molding. The polymeric main body can be formed of multiple injection molded parts that are joined, or formed as a single piece. The injection molding can include applying between approximately 700 bar and approximately 1100 bar of pressure where at least a portion of the internal surface contacts a mold surface.

A storage tank for storing water, waste, or other material is provided where the storage tank has co-moulded external features for fittings. A method for manufacturing such a storage tank is also provided.

A liner discharge structure, and associated liner and container system are disclosed. The liner discharge structure includes: a collar fabricated from a liner material, wherein the collar encapsulates an O-ring in the liner material; a substantially rigid section having an opening, wherein the substantially rigid section is fabricated from the liner material; and a neck fabricated from the liner material, wherein the neck provides a passageway extending between the opening in the substantially rigid section and the collar; wherein the liner material used to fabricate the substantially rigid section has a cross-sectional thickness greater than the liner material used to fabricate the neck.

A subsea storage tank for the storage of bulk fluids is adapted for being set on the sea floor, and is adapted for supplying to local subsea oil and gas production facilities a wide variety of production support fluids. The subsea storage tank includes an inner and outer shell, the shells being adapted so that a barrier fluid can be inserted into and between the shells. An interior barrier separates the interior stored fluid from sea water that is free to enter into the tank, on the opposite side of the barrier, to compensate to the varying volume of stored fluid. An identical tandem barrier is formed nearly identical to the first barrier, and is formed and positioned so that the two barriers act together, and so that the space between them can contain fluid as well, and acts like a bladder.

An exterior cover of a generally rectangular flexible tank for a 40 foot shipping container has longitudinal seams along the long sides of the flexible tank rather than at the ends. The exterior cover is air-tight and contains holes near the ends of the flexible tank. The exterior cover is made of a flexible vinyl material that is optimized for the flexitank. The flexible vinyl material consists of an inner scrim core of woven fibers coated with melted PVC which goes through the holes between the woven fibers.

The present invention relates to a protective device (14) for a container (12) for receiving substances, in particular pulverulent substances, wherein the protective device (14) has a flexible casing (32), which encloses a casing space (38) and comprises a first casing opening (34), and a first tubular body (40) which is connected to the casing (32) in the region of the first casing opening (34) and which has a first mating container connection unit (46), a primary first end (42) and a primary second end (44), wherein the first tubular body (40) is connected to the casing (32) in such a way that the primary first end (42) terminates with the first casing opening (34) or projects into the casing space (38), and the protective device (14) can be connected to the first container connection unit (24) by means of the first mating container connection unit (46) in such a way that the casing (32) can be introduced into the interior (18). The invention further relates to a protective arrangement (10) comprising such a container and such a protective device (14).

Shipping system for temperature-sensitive materials. In one embodiment, the shipping system includes a frame defining an enclosure. The frame includes a bottom, a top, a front, a rear, a left side, a right side, a left corner gusset, and a right corner gusset. The front serves as a door. Thermal breaks are provided in one or more of the bottom, the front, the left corner gusset, and the right corner gusset. Vacuum insulated panels are positioned along all sides of the frame. Many of the vacuum insulated panels are encapsulated between the frame and an outer shell. A plurality of phase-change material assemblies are positioned within the frame along all sides. Heat-spreaders are positioned interior to the phase-change material assemblies. The shipping system are dimensioned so that four such shipping systems are seated on a prorate manual cargo sheet.

The application relates to a flange member, a valve, a liquid bag, and a container. The flange member includes a tube body and a flange plate, and a first passage runs through the inside of the tube body, the two ends of the first passage being respectively a first inlet end and a first outlet end, the inner wall of the tube body having an annular flange extending into the first passage, and the annular flange being closer to the first outlet end. The tube body extends through the flange plate in the axial direction of the flange plate and is connected to the flange plate, and the flange plate is closer to the first inlet end. The flange member reduces the pulling force on the liquid bag at the edges of the flange member, thereby reducing the probability of damage to the liquid bag due to the pulling force.
