A weighting device for audio equipment may include a container and an outer casing. The container includes an interior volume that contains or is configured to contain a filler material and that is defined by one or more sidewalls that are impermeable to the filler material. The filler material may include a liquid, solid, slurry, or non-Newtonian fluid. The outer casing includes an interior volume configured to receive the container. The outer casing has an exterior side comprising a rubberized material, non-abrasive material, slick material, soft cloth, or non-abrading polymer material to prevent damage to the audio equipment.

A two-panel bag constructed from first and second panels that each has the same shape and size. The panels are connected together and a top edge is open for accessing the interior space. The top edge of the panels form handles that can be tied together to close the interior space. The two panels have a laterally inverted shape relative to a centerline. The top edge of each panel further includes two identical sections that each has a vertically-and-rotationally inverted shape. The shape of the panels facilitates manufacturing as the panels can be cut from a flat sheet with limited or no wasted material.

An improved bag for carrying a plurality of items and methods of using the same are disclosed herein. In a preferred embodiment, the bag is made from a biodegradable material, such as paper, and the bag is used for carrying ice. The paper of the bag may be coated in a biodegradable wax laminate, such as a plant-based or animal-based wax, for increased water resistivity.

A radiator containment bag includes a bag section configured as a container and sized and shaped so that in use at least the lower end of a radiator fits within and is retained by the bag section. The bag section is formed at least partly from a waterproof material so that liquid in the bag section will be retained within the bag section. At least one containment strap is connected to the bag section and is configured to pass over and around the top of a radiator located in the bag section in use to hold the radiator in the bag section. A plurality of grab handles extends from the bag section and are configured to allow a user or users to grasp the handles to lift the

Disclosed fluid reservoirs include closure mechanisms for sealing an upper opening of the reservoir. The reservoir can have plates adjacent the upper opening. When the upper end of the reservoir is folded, the plates can be positioned on opposite sides, and a closure frame can be slid over the plates to pressure them together. The plates can have pins that engage with slots in the closure frame, and a separate closure lock can be slid over the end of the closure frame to prevent the pins from exiting the slots. The plates can also bias the opening open when the closure is not engaged. Also disclosed are flexible fluid reservoirs that include structural elements, such as baffles, that help retain a desired shape of the reservoir when filled or empty. Some baffles can be elastically deformable to allow flattening and expansion of the bladder while biasing toward a neutral position.
