Abstract: A liquid dispenser includes a liquid container enclosed by a support member that thermally insulates the container and provides rigidity for the overall structure. A cover encloses the support member and the liquid container, providing an added layer of insulation. Preferably, lightweight materials are used for the support and the liquid container. Materials for the support may include, for example, EPP, EPS or Arcel® material. Materials for the liquid container may include, for example, of polycarbonate, nylon, SAN, and polyethylene.

Abstract: A rack for transporting and storing carriers includes a base, rolling members connected to the base, a frame, and a bumper portion. The base may include projecting portions extending outward relative to the corner regions of the frame. The frame extends upwardly from the base and includes supports for supporting carriers. The supports have metal surfaces for contacting the carriers. The bumper portion is disposed on at least a peripheral portion of the rack and is formed of plastic. A first elongated restraining member may be provided to inhibit carriers from being removed from the frame.
