Definitions

  • the invention relates to a heat-insulating transport and serving tray for meals with a lower tray part, which accommodates at least one individual food container in several recesses, with a cover for the food container.
  • Such transport and serving trays serve to accommodate a complete menu portioned into the individual food containers during transport and also during subsequent serving.
  • the food in the individual food containers should be thermally insulated.
  • a complete menu consists, for example, of soup, a three-part main course, salad or dessert, with cutlery, a napkin, a coffee cup or a glass and a dinner plate on the tray.
  • a preferred area of application for such transport and serving trays is, for example, institutional catering for patients and staff in hospitals.
  • the recesses receiving the individual food containers are each designed as almost molded troughs.
  • the tray is closed with a cover, which also represents the closure for the individual food containers.
  • the heat-insulating design of the lower part of the tray is associated with a relatively large production outlay because it is either produced as a hollow body in the blowing process or because a multi-layer structure in sandwich construction, consisting of a lower shell, an insulating intermediate part, for example as a foam or as a separate insulating insert, and an upper shell is required.
  • the division and the size of the recesses are for individual food containers set; if a different division and / or size of the individual containers is desired, a different, again very expensive tool is required at least for the upper shell.
  • the object of the invention is therefore to provide a transport and serving tray of the type mentioned which is simpler in construction while maintaining the heat-insulating property, so that production is simplified. Its individual parts should be designed in such a way that they can be easily cleaned and that there is no risk of food residues and dirt remaining in inaccessible interior spaces after damage.
  • the transport and serving tray should be able to be carried out with little effort for the production changeover for different arrangements and / or sizes of food containers.
  • the cover is intended to effectively prevent individual dishes from overflowing from the food containers.
  • an insert mask removably arranged in the lower tray part has a plurality of openings which form the recesses for the individual food containers, that between the lower tray part and the insert mask there is a cavity into which the individual food containers protrude at a distance from the lower tray part, and that the individual food containers are each closed with a container lid.
  • the essentially still air forms in the cavity between the insert mask and the tray an effective insulating layer that isolates the individual food containers from the environment and also from each other. Since the insert mask can be easily removed, cleaning is not difficult, since the lower part of the tray is a single-walled, smooth shell and the insert mask is a single-walled, smooth part with openings.
  • the container lids close each individual food container so that individual, in particular liquid, food is prevented from escaping.
  • the openings in the insert mask each have a countersunk centering edge which receives an edge flange of the food container.
  • the container lids each have an outwardly projecting edge flange which fits into a circumferential fold formed by the countersunk centering edge of the opening in the insert mask. This fold centers both the food container and the container lid in the embodiment with thin-walled food containers made of, for example, stainless steel sheet.
  • the container lids can each have a centering edge projecting into the food container.
  • a centering of the container lid in the upper edge of the food container is also achieved in the event that the food container is thick-walled, for example made of insulating material, so that the outwardly projecting edge flange of the container lid would no longer be centered in the fold of the centering edge of the opening.
  • the container lid is designed in its central region with an upwardly domed lid dome, which fits into the food container when the container lid is arranged in reverse order Lid dome put on.
  • the upward-arching domed lid would make the air above the food too large, so that the food would cool down more quickly. Therefore, the container lid is designed as a reversible lid, which in this case is placed with the lid dome arched downward, so that the air content above the food is significantly reduced.
  • the container decals are preferably made transparent so that the contents of the container can be seen without having to remove the container lid, which would accelerate cooling.
  • the design of the individual food containers made of heat-insulating material is particularly useful when hot and cold dishes are to be included in the tray at the same time.
  • a dinner plate is placed in one of the openings of the insert mask, with a plate recess optionally pointing upwards or downwards.
  • the reverse arrangement of the dinner plate during transport prevents contaminants from getting into the plate recess.
  • the dinner plate is only turned over immediately before use.
  • the omission of an overall cover for the tray, which is replaced by the individual container lids, does not therefore have a disruptive effect on keeping the dinner plate clean during transport without having to provide a separate lid for the dinner plate.
  • the food containers are formed in one piece with the insert mask. This eliminates the need to use separate food containers, so that the manufacturing effort for the tray is reduced overall. In addition, the number of individual parts is much smaller.
  • the insert mask has a pulled-down edge. This allows the lower part of the tray to be designed with a lower edge.
  • the insert mask is expediently sunk in the area of the EB plate, so that the dinner plate is arranged lower than would result from the depth of the food containers. This arrangement allows a more convenient meal.
  • the transport and serving tray has a recessed lower tray part 1, which also forms the carrying tray.
  • the tray lower part 1 and the insert mask 3 are preferably made of plastic; the food containers 5 are made of stainless steel sheet in the embodiment of FIGS. 1-4.
  • Each food container 5 is closed with a separate container lid 9, which consists of transparent polycarbonate.
  • the openings 4 of the insert mask 3 each have a countersunk centering edge 10 which forms a circumferential fold 11.
  • this fold 11 is an edge flange 12 of the food container 5 and - in the embodiment according to FIGS. 3 and 4 - also an outwardly projecting edge flange 13 of the container lid 9 is centered.
  • the container lid 9 is designed in its central region with a lid dome 15 arched upward in the arrangement according to FIGS. 3 and 5. In this arrangement, an additional space is available above the food container 5, which allows bulky dishes to be accommodated in the food container 5.
  • the container lid 9 is arranged in the manner shown in FIG. 4 with the lid dome 15 pointing downwards in order to reduce the air volume in the food container 5 above the food.
  • the dinner plate 6 is arranged upside down over the associated opening 4. Cams 16 lying on the edge of the opening 4 center the dinner plate 6; it is removed and used before use (Fig. 2).
  • the insert mask 3 is provided with a pulled-down edge 17, so that the lower tray part 1 can be designed with a lower edge than in the previously described embodiment.
  • the insert mask 3 is lowered, so that the dinner plate 6 is arranged lower than the upper edge of the food container 3.
  • a cover clocbe 18 can be used for the dinner plate 6 when e.g. a stew is offered, which is already included in the dinner plate 6 during transport.
  • the dinner plate 6 and the cover cloche 18 are centered together by the cams 16.
  • the upper, peripheral edge 2 of the tray closes partly 1 a corresponding, circumferential handle edge 19 downwards, so that the edge formation of the lower tray part 1 is T-shaped in cross section.
  • the grip edge 19 allows the tray to be pulled out of cupboards, trolleys or frames.
  • Fig. 7 it can be seen that in the embodiment shown there the food containers 5 are made in one piece with the insert mask 3, i. H. the removable insert mask 3 has bowl-like or cup-like depressions in various expedient sizes and different numbers, which form the food containers 5.
  • a recessed centering edge 10 is formed in the insert mask 3 in the region of the upper edge of the food container 5, which centers the cover 9, which can be designed, for example, as described in FIGS. 3 and 4.
  • the arrangement and size of the food containers and the other parts of the transport and serving tray shown in FIGS. 1 and 2 represents only one embodiment which can be modified in a simple manner as required. To do this, it is only necessary to replace the insert mask 3, so that a subsequent change is easily possible.
  • the size, shape, number and type of the food containers, the cutlery holder and the dinner plate can be changed as required within the overall size of the tray.
  • the insert mask for normal food and different types of light food can be unmistakably marked.
  • the outer dimensions of the tray described are expediently designed according to the recommendations of the international standard of the so-called "Gastronorm” (530 mm x 325 mm). Most institute kitchens and food distribution systems around the world are equipped with transport and storage devices designed for these dimensions. However, it has been shown that this "gastronorm" dimension is usually too small when using conventional trays and serving parts. In the case of the tray described, however, these standardized dimensions can be maintained in most cases by rational use of space, in particular extensive use of space by rectangular food containers 5 (as shown in FIG. 1) and edge formation according to FIG. 7 are made possible. It is even possible to use conventional trays as tray lower parts together with a described insert mask with the edge 17 pulled down in the manner described.
  • the insert mask 3 can have an upwardly directed, peripheral edge 20 which can be continuous or interrupted.
  • the edge 20, which can also be provided in the embodiment of the insert mask 3 according to FIGS. 1-5, serves for the optical marking of the outer edge of the tablet and for dirt trapping.
  • Fig. 7 it is indicated with dashed lines that the insert mask 3 in the area of the dinner plate 6 can have a downwardly directed collar 21 which separates the air space between the food containers 5 and the dinner plate 6.
  • a modified embodiment of a container lid 9 ' is shown which, in addition to the centering edge 14, has a further centering edge 14' on the cover side opposite the centering edge 14, the outer diameter of which is larger than that of the Centering 14 is.
  • the centering edge 14 with the smaller outer diameter serves to center the container lid 9 'in a plastic food container 5 (FIG. 8a).
  • the container lid 9 ' is placed in such a way that the centering edge 14' with the larger outer diameter projects downwards and fits into the food container 5, the inner diameter of which is larger than that of one due to the smaller wall thickness Plastic food containers.
