Definitions

  • the invention relates to a transport unit for the transport of different types of and in particular differently tempered dishes under heat insulation with the components mentioned in the preamble of claim 1.
  • the insulating container mentioned there with a tray-like lower part and a lid is also referred to as a "temperature-maintaining tray”.
  • Transport units of the type mentioned are required for hospitals, sanatoriums, retirement homes, training centers, the hotel room service, an on-board service, in particular for airplanes and the "food on wheels" to be distributed by central kitchens.
  • the invention relates to measures which all relate to the same transport unit but are also intended to enjoy independent protection in part, which is why a number of claims with "in particular” refer back to the preceding ones.
  • the contact surfaces between the lid and the lower part along the circumference are longer than if they were in a main plane of the insulating container. As a result, the heat emission to the outside is reduced. The emission of food odors to the outside is also reduced.
  • the insulated container should be used to transport food of different temperatures, e.g. B. warm soups and meat dishes as well as cool salads and drinks. It should therefore be ensured that the temperature exchange between the recesses in the lower part and cover is possible remains as low as possible.
  • the recesses of the lower part and the edges of the shells can be designed so that flat shells can be hung with their edge on the edge of the recess.
  • filled shells can be easily gripped at their upper edge for removal.
  • the insulating container consists of a lower part 2 and a matching cover 4.
  • the external dimensions correspond approximately to the EURO standard and are approximately 526 x 364 mm (EURO standard 530 x 370 mm).
  • the lower part and cover consist of deep-drawn plastic shells 6 to 9. Two of these shells are combined to form the lower part 2 and the cover 4, e.g. B. welded. In between there is a thermal insulation filling made of polyurethane foam.
  • buttons 12 are provided on the top of the cover 4 .
  • Nubs 14 are provided within the depressions, the upper sides of which are flush with the other upper surface of the cover.
  • the knobs have the shape of a circular ring, with two knobs in the middle complementing one another to form a circular ring, while at the two ends of the recess there is only one knob in the form of an approximate semi-circular ring.
  • feet 16 are provided, which have the shape of circular disks and fit into the knobs 14. In this way, as shown in Figure 3 on the left, two insulating containers can be stacked on top of one another and secured against slipping sideways.
  • the knobs 14 serve a second purpose, namely to secure the shells 18 against slipping. Six such trays can be safely placed on the lid.
  • the lower part 2 and cover 4 have outer contact surfaces 20, 21, which run obliquely to an imaginary horizontal central plane, and drop outward at about 40 ° with respect to the horizontal.
  • the edge of the lower part and cover are formed by circumferential ribs 26, 27.
  • the inclined position and the kinking of the slots between the contact surfaces reduce the heat emission and the odor emission to the outside.
  • the inclined contact surfaces 20 and the circumferential rib 26 together give the impression of a particularly low lower part.
  • depressions are provided in the lower part, namely an elongated depression 30 on each of the two narrow sides, which is rectangular except for roundings at the corners. Between the two depressions 30, two depressions 32 are provided, except for rounded corners have a square shape.
  • Matching recesses 34 and 36 are provided in the lid. Between the recesses, the lower part has walls 38 of considerable width in the transverse direction and in the longitudinal direction. The top has corresponding walls 39, too quite wide. The width alone severely limits the heat exchange between the individual wells and dishes at different temperatures. Another measure is that contact surfaces 40 and 41 of these walls have matching curvatures. This in turn also widens the slots between the contact surfaces, which additionally reduces the exchange of heat and odors.
  • the walls 38 of the lower part have a greater width at the top than the walls 39 of the cover, so that there is still space for edges 46 of shells (see FIG. 4 on the left).
  • the trays to be used are thin-walled, but can have different shapes.
  • FIG. 1 shows a flat square tray 44
  • FIGS. 4 and 8 show a flat rectangular tray 45.
  • Such trays hang with their downwardly bent edge 46 on the edge of the depressions 30 or 32.
  • Deep thin-walled trays 48 of square shape or 50 of rectangular shape stand with their bottom 52 or 53 on the main bottom 55 of the rectangular or square recesses. Lids 57 or 58 are mainly used to cover the deep shells.
  • the bowls 18 have an insulating wall 60 and serve to hold hot dishes such as soup or porridge.
  • These shells are preferably circular, but in any case have a circular bottom 62, in particular with a circumferential annular bead 61 as a standing surface.
  • an annular groove 63 is provided inwards of the annular bead 61, which has a suitable size for fitting over the knobs 14 in the lid 4 of the insulating container (FIG. 3).
  • additional flat circular depressions 64 are provided, which serve to receive the bottoms 62 of such shells 18. In this way, trays of three different heights can be picked up from the depressions. While the shells 18 rest with their circular bottoms in the circular depressions 64, the square bottoms of the shells 48 stand on the main bottoms 55 of the depressions 30 or 32, while the flat shells 44 and 45 hang with their edges on the edge of the depressions.
  • each of these depressions has a flat elevation 66 of such shape and dimension that the side walls of the shells 48 laterally abut tips 68 of these elevations. This is particularly important in the event that only one shell 48 is accommodated in a long depression 30.
  • the total height from the main floor 55 of the depression of the lower part to the floor 72 of the associated depression 74 of the upper part is such that it has the height of a deep shell 48 including its shell lid 58 and a lid handle 76.
  • the lid 4 of the insulating container is put on, the shell lid is held closed.
