A portable, pumpless water ballast system can be constructed of a flexible water-proof membrane molded or formed of welded panels to make a desired shape, such as cube-shaped when filled with water. Along the top side is an opening for filling the container. A water-proof closure is provided in the opening to prevent water leaking out. An air release valve can be installed near the top area of the container's top or side panels. A handle or strap can also be provided on one or more of the adjacent sides of the container. A plastic threaded drain and closure can be provided on one or more sides to allow for emptying of the container or to attach other features like a hose or other accessory.

A box comprising: a first pair of opposing side panels; a second pair of opposing side panels connecting the first pair of side panels; a pair of top panels, each top panel joined to one of the side panels of the first pair of opposing side panels; and a handle assembly, the handle assembly comprising: a handle portion, the handle portion attached to one of the pair of top panels, the handle portion comprising a tab at a side end of the handle portion, and a locking panel, the locking panel attached to one of the side panels of the second pair of side panels, the locking panel defining a cut pattern, the cut pattern defining a space therewithin; wherein the space within the cut pattern is configured to receive the tab; and wherein the handle portion is configured to fold from an upright configuration to a folded-down configuration.

A medium storage box includes a storage unit that stores a medium, a handle configured to rotate in a first direction from a first state to a second state and a second direction opposite to the first direction from the second state to the first state, and a rotation restricting portion that prevents rotation of the handle in the second direction. The handle includes a grip portion and an arm that includes an upper surface portion or a top portion and extends in an extending direction toward the upper surface portion or the top portion from the rotational axis. The arm is configured such that an end portion of an arm center line side in the upper surface portion or the top portion is separated toward a first direction side with respect to an arm center line extending from the rotational axis to the extending direction.

Handles for containers and sterilization containers are provided. For example, a handle for a sterilization container comprises a base portion, a grip portion connected to the base portion, and a stop. The base portion is repositionable with respect to the container to change an orientation of the grip portion with respect to a bottom surface of the container. In some embodiments, a sterilization container comprises a body having a bottom surface, a lid, a first handle attached to a first end of the body, and a second handle attached to a second end of the body. Each handle includes a base portion rotatable within a plane parallel to the respective end of the body to reposition the handle with respect to the body, which changes an orientation of a grip portion of each handle with respect to the bottom surface.

A handle structure includes a handgrip body and at least one rotating body. The rotating body is pivotally connected to the handgrip body, the rotating body is used to pivotally connect a first object, and when rotating, the rotating body drives the handgrip body to move toward the first object for reducing the height of the handle structure. Therefore, the handle structure can make a handgrip body moved out toward a direction distant from the first object when used, and can make the handgrip body moved in toward a direction of the first object when not in use for reducing the height of the handgrip body so as to operate and use easily and prevent collision.

A handle and assembly for a bucket. The bucket has first and second attachment regions on the inner surface of the sidewall near the rim. The sidewall has a compressed condition in which compressive forces are applied to opposite sides to reduce the distance between the attachment regions, and a relaxed condition with forces. The handle has attachment ends with an axis between them. The attachment ends attach to the attachment regions such that the handle rotates about the axis and can also move laterally along the axis. The handle has a first rotational position in which the handle is above the rim, and a second rotational position in which the handle is below the rim. The handle cannot rotate between the first and second positions when the sidewall is relaxed, but can when the sidewall is laterally compressed.
