    Abstract: The subject matter of the invention is a bottom panel for ventilated containers. The bottom panel is provided with an upper surface plate layer (1) and a lower surface plate layer (2), both layers being held in position by means of a spacer layer (3) of rigid foam. The upper surface plate layer (1) is an extruded profile consisting of a flat plate (4) and rib profiles (5), whereby the rib profiles (5) have a cross section of closed hollow profiles. The closed hollow profiles can be used as ventilation channels (7), which are linked to the grooves (6) between the rib profiles (5) by means to openings (8).

  • Patent number: 4441678
    Abstract: A mounting for a tank receptacle in a lattice-shaped, stackable, cage-like supporting framework surrounding the receptacle. The receptacle is supported in the framework at three points in the case of a supporting framework which is not torsionally rigid relative to the receptacle. Where the receptacle is supported at four points in the framework, two support points are defined by hinges connected to each other through equalizing connecting rods. A strap connects the receptacle to the framework at each support point, a lever being located between each hinge and its respective strap. Spring-loaded buffers limit the movement of the levers.

  • Patent number: 4286507
    Abstract: A shipping container comprises a container body which has a top, bottom and side walls with at least one of the side walls of the container having upper and lower longitudinally extending hollow chords. Each of the chords have top and bottom openings and interior baffles arranged to slope downwardly toward the openings for the removal of water and dirt entrained with air moving therethrough. The bottom wall of the container has a substantially U-shaped longitudinally extending beam which is located intermediate the length of the bottom wall and opens downwardly and has a top with at least one aperture therethrough and spaced upon said walls. A plurality of baffles are exposed in the beam and extend from a side wall downwardly toward the opposite side wall but terminate at spaced locations from the wall so that there is a downward opening therebetween.

  • Patent number: 4169407
    Abstract: A side wall construction for a container for shipping goods includes upper and lower hollow tubular chords which are interconnected by a side wall portion. Each chord is of substantially rectangular configuration and includes a lower downwardly sloping wall with a bottom opening directly adjacent the downwardly sloping wall in the adjacent wall and with a top opening vertically offset and diagonally opposite the lower opening. The interior of each chord is provided with a plurality of downwardly inclined and oppositely directed sheet metal deflectors. The deflectors advantageously extend inwardly from respective opposite walls and the clearance between the end of the deflector with the adjacent opposite wall is smaller than the cross-section of the openings in the chords.
