Definitions

• Figures 9a, 9b the top view of a third exemplary embodiment of a lower part or upper part of a transport container for a seal according to FIGS. 3 and 4;
• This tongue and groove connection should be designed so closely that it also ensures that the upper part 18 sits firmly on the lower part 2 and a clamp is generated when pressed together. This is favored if the groove 21 and / or the tongue 5 is slightly undercut; see. Figure 7.
• the tongue and groove connection adjoins the lower part 2 or the upper part 18 on horizontal surfaces 4, 20 which abut one another and form abutting surfaces.
• this form of the food carrier 11 is not the only possible one. Round food carriers 11 with compartments 13 are also conceivable (see FIG. 2B), and the webs 14, which separate the compartments 13 from one another, can also be curved, for example. Instead of a stacking edge 17, the edge 12 of the food support 11 can be made somewhat thicker and the compartments 13 can be conical. When the food carriers 11 are stacked, the compartments 13 then slide into one another, so that the edge 12 acts as a stacking edge. The edge 12 can also be provided with handles.
• the shape of the lower part 2 of course corresponds essentially to the shape of the associated food carrier 11. The variants in the contour of the food carrier 11 are compensated for by the inserts 7 (see FIG. 7), so that the lower part 2 is suitable for the transport of different food carriers 11 with the same basic shape (round, square, square, oval, etc.) .
• the surface 20 of the side walls 19 which forms the abovementioned abutment surface has a groove 21 into which the circumferential strip 5 engages when the upper part 18 is placed on the lower part 2, so that the aforementioned tongue and groove connection is produced, which ensures that the upper part 18 is firmly seated on the lower part 2 and a clamp is generated when pressed together.
• the surface 20 has a recess 22 in which a pressure surface 23 is arranged as a pressure element.
• the lower parts 2 in a uniform size and at the same time allow not only variations in the contour, but also relatively large tolerances in the production of the food carrier 11, which is unavoidable, for example, with porcelain food carriers 11 due to the material.
• the food carrier 11 slides along the inserts 7 as far as into the lower part 2 until it is held in a clamping manner by the inserts 7.
• the inner lid 25 and then the upper part 18 is placed on it, so that the strip 5 engages in the groove 21 and provides a clamping hold.
• the cover 31 of the inner cover 25 is pressed when the upper part 18 is placed through the pressing surface 23 onto the upper side 15 of the webs 14, so that the compartments 13 of the food carrier 11 are sealed off from one another.
• a pressing surface with a corrugated or ribbed surface can form pressure points with the upper sides 15 of the webs 14 at different heights and thus compensate for level differences in the webs 14 due to production.
• the upper part 18 can have two recesses 32, 33 on the front and the lower part 2 on the side surfaces for supporting the handle have two recesses 34, 35 about 5 mm deep. They are arranged so that you can grip with the thumbs of both hands in a recess 32, 33 on a front of the upper part 18 and with the index fingers in a recess 34, 35 of a side surface of the lower part 2 and both parts 2, 18 thus easily and can slide apart to open the transport container 1 without slipping.
• FIG. 8 A top view of a further exemplary embodiment of an upper part 118 is shown in FIG. 8, structural elements which have remained unchanged bearing the same reference numerals as before. It can be seen that there is no pressure surface 23 in the recess 22, but rather pressure strips 123, the course of which corresponds to the course of the upper sides 15 of the webs 14, which separate the compartments 13 of the food carrier 11 from one another. It can also be seen that the pressure strips 123 have a two-fold symmetry about the axis of rotation D, ie when the upper part 118 is rotated through 180 " , the pattern is again the same. The upper part 118 can therefore be placed on the lower part 2 in any orientation without To fear that the webs 14 and the pressure bars 123 do not come to lie on top of each other.
• the upper part 318 is constructed in principle like the upper part 18 and corresponds in its dimensions to that of the lower part 302. Since the additional food carriers in the exemplary embodiment are provided as round trays without compartments, a pressing point 333 is sufficient as a pressing element. As a counterpart to the recess 338 for the cutlery 339, an insert 334 is provided on the surface 20.
• FIG. 10A shows a longitudinal section through an assembled packaging system, in which the food carrier 11 is inserted into the lower part 2 and from the Upper part 418 is closed.
• the upper part 418 of the transport container 401 is a composite body comprising a lid 420 and a seal 421.
• the lid 420 forms the counterpart to the lower part 2, as has already been described for FIG. 3.
• the recess 22 of the cover 418 is covered with the seal 421, which is held on the inside 24 of the side walls 19 in undercuts 423.
• This composite body made of cover 420 and seal 421 ensures that the contents of the food support 11 are sealed in such a way that they are not spilled during transport and further handling.
• the food carrier 11 is pressed against the seal 421 when the upper part 418 is placed on it.
• the seal 421 is soft enough to give in to the pressure exerted on it, on the other hand it is thick enough not to let the food carrier 11 come into contact with the recess 22 in the cover 420.
• the seal 421 By pressing the seal 421 onto the webs 14 of the compartments 13 of the food carrier 11 it is ensured that the compartments 13 are sealed so that their contents are not spilled during transport and further handling.
• cutouts 423 can be provided in the seal 421, which correspond to the compartments 13 of the food carrier 11 to be inserted into the lower part 2.
• the cutouts 423 are delimited by webs 424, which are congruent with the upper side 15 of the webs 14 of the compartments 13.
• a particularly suitable material in addition to flexible silicone foam is expandable ethylene vinyl acetate (EVA). It is a cross-linked 100% waterproof plastic material.
• the seal 421, facing the food support 11, has one or more flat surfaces. Due to the choice of materials, these surfaces are completely waterproof. Such flat surfaces are easy to manufacture, e.g. also because the required shape is then flat and correspondingly simple. In addition, a flat surface is easy to clean, for example by wiping it.
• FIGS. 11A, 11B and 12 show an alternative to the described tongue and groove connection of upper part 18 and lower part 2, which can be combined with all of the sealing variants described here.
• It consists of a bracket 40, which holds the upper part 18 and the lower part 2 together, and thus also ensures a suitable contact pressure of the pressing surface 23 or the seal 421.
• the bracket 40 is in two parts, formed by a rectangular holding section 41 and an L-shaped clamping section 42, the latter made of spring steel.
• the holding section 41 surrounds a correspondingly shaped holding projection 43 on the lower part 2.
• the clamping section 42 articulated on the holding section 41 at 43 engages over the upper part 18 due to its L-shape and presses it against the lower part 2.
• the clamping section lies in slots 44 in the upper part 18.
• the edge 12 is sealed by the fact that the upper, horizontally ground sealing surface 12 'rests on the surface 723' of the upper part 718 and the edge 12 also on its sloping edges on one side of the webs 724 and up the other side is surrounded by the beads 725.
• the aforementioned clamping connection of the upper part 718 and lower part 2 by means of a groove (21) / tongue (5) connection, preferably forced by the slight undercut of the groove 21 and the tongue 5, ensures that the sealing surfaces 12 'and 723' are pressed together, which results in a satisfactory sealing of the compartments 13 for transport.
• the upper part 718 has the recesses 727 on its inner horizontal surface 726, so that the food in the compartments 13 can be piled up correspondingly higher.
• the recesses 727 are opposite the edges 12 ', as shown in FIGS. 13 and 14A, by an amount 1, which is e.g. Can be 8 to 15 mm, reset.
