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 device for facilitating removal of a drop tube from an underground liquid storage tank, comprises a plate configured to fit within a spill restrictor fitted to the underground liquid storage tank. The plate may comprise a first main surface; a second main surface that is separated from the first main surface by a thickness of the plate, the second main surface being configured to rest on a bottom surface of the spill restrictor; a first truncated portion configured to clear any structure projecting from the bottom surface of the spill restrictor when the device rests on the bottom surface; a centrally-disposed opening configured to conform to and fit over a collar that is configured to attach to a riser pipe that rises from the underground liquid storage tank and to the drop tube; and at least one peripherally-disposed through hole traversing the thickness of the plate, the at least one peripherally-disposed through hole being configured to enable a elongate bar to be inserted therethrough and make contact with the bottom of the spill restrictor.

A flexible bag (1; 101; 201) comprising a component (3; 103; 203) inside the bag, wherein said flexible bag comprises a receiving device (5; 105; 205) provided in a wall (7; 107; 207) of the flexible bag, wherein said component (3; 103; 203) and said receiving device (5; 105; 205) are configured for being connectable to each other for keeping the component substantially stationary within the flexible bag when so connected.

A dispensing port adapter device for preventing a loss of pellets from a feed tube to a suction tube includes a sleeve extending from a first end to a second end. A chamber space is defined within the sleeve and the second end receives the feed tube of the railway car hopper into the chamber space of the sleeve. An end wall is attached to the sleeve and covers the first end. The end wall has an aperture extending therethrough to receive the suction tube. A securing member is mounted on the sleeve and secures the sleeve to the feed tube wherein an outlet of the feed tube is positioned within the chamber space. A seal is attached to the end wall and covers the aperture to prevent the pellets from exiting the sleeve through the aperture.
