A container may comprise a support frame with sides and at least one of the sides being an open side defining an opening, a flexible panel configured to at least partially cover the open side of the support frame, and a panel mounting assembly configured to removably mount the panel over the opening. The panel mounting assembly may comprise at least one panel mounting element including a leverage structure configured to provide a fulcrum edge along at least a portion of the opening, with the at least one portion of the panel being tensionable over the fulcrum edge. The panel mounting element may also comprise a tensioning structure mountable on the leverage structure and configured to selectively apply tension to the at least one portion of the panel with the thicker thickness over the fulcrum edge of the leverage structure.

The portable liquid and material container of the present invention includes a base, sidewall, and rim. The sidewall is attached to the base at a sidewall angle and forms a base lip at the junction between the base and the sidewall. The rim is attached to the sidewall opposite the edge joined to the base, where the rim diameter is smaller than the base diameter. The large base provides stability to the container in the various types of environments. The narrow opening prevents and minimizes the liquid within the container from escaping. The sidewall angle positions the sidewall inwards towards the center of the container to direct liquid traveling up the sidewall towards the center of the container to prevent the liquid from escaping over the rim. The container is collapsible for easy transportation and requires no tools for assembly.

The present invention is an alignment device for a bag containing one or more ports. The alignment device is attached to either the one or more ports or to the bag adjacent the one or more ports. The plate has an indicator or a unique outer edge shape that is designed to fit into a corresponding unique opening in a holder to ensure proper alignment of the bag and its port(s) in the holder. The plate is has a series of holes equal to and in alignment with the one or more ports of the bag and the port(s) extend through the holes of the plate.
