  • Patent number: 5419456
    Abstract: The present invention pertains to a design of the connection between the lower end of a side wall plate 1 and the corresponding longitudinal edge of the bottom plate 2 of a large container. Both the side wall plate 1 and the bottom plate 2 are prefabricated sandwich plates. After the two plates 1, 2 have been joined, a free space 12, which is subsequently filled with foam, is initially left in the transition area between the side wall plate 1 and the bottom plate 2. The transition area or the free space 12 that is subsequently filled with foam is covered, on the one hand, by an inner cover profile 13 between the upper cover plate 7 of the bottom plate 2 and the inner cover plate 4 of the side wall plate 1, and, on the other hand, by an outer cover profile 11 between the outer cover plate 3 of the side wall plate 1 and the lower cover plate 6 of the bottom plate 2.

  • Patent number: 5201340
    Abstract: The present innovation pertains to a device with which containers, in which water collects in an unintentional manner, are automatically drained. An outer housing (2, 3), which can be inserted into the bottom of the container, is subdivided by a web (8a) into two chambers, one of which is connected to the interior of the container, and the other of which is connected to the surroundings of the container. The web encloses an opening (20) which connects the two chambers when a valve member (14) has moved away from a seat (8b) enclosing the opening. If the valve member rests on the seat, the chambers are separated from one another, and the interior space of the container is not in connection with the surroundings of the container. The movement of the valve member is controlled by the water level in the chamber which is in connection with the interior space of the container.

  • Patent number: 5050402
    Abstract: The invention is directed to a container for environmentally controlled and temperature-regulated transport of perishable goods, the environment-controlling unit being arranged in the essentially cuboid container in the region of the one end face thereof as a component, which is to be allocated to the container and to be separated from it. The environment-controlling unit is broken up into functionally connected components, or is composed of components, which are functionally connected with one another, the components being allocated to the region or regions between the temperature-regulating unit and a container corner post at the side of the temperature-regulating unit. In this way, space within the container is utilized, which previously was unused and was filled with foam, as were the container side walls, in order to avoid heat bridges.
