Characteristic of the known technical solutions

Bs is known in accordance with patent 85 277 _S container for liquids, especially for water transport to produce, having a container insulation in the form of composite construction. These are containers in the form of a single boiler, which is fixed by laminated fasteners with a chassis. Such containers have a closed insulation and are also particularly suitable for biologically sensitive transport goods, such as milk »due to their high insulating effect. From these viewpoints has become known, large container in the manner described with complete insulation and. "Laid together to attach to a chassis to transport larger quantities." The spaces between the boilers were provided with covers to give the whole a uniform look and to avoid heavy soiling. In isolation, each boiler acts as such "The covers between the boilers do not have such a function." This type of arrangement of boilers to large containers creates a considerable expense of additional costs due to material and working time »because each container has complete insulation« On the other hand, greater distances the boiler is maintained with respect to each other, which has an unfavorable effect on vehicle construction, creates considerable dead spaces, adversely affects the payload factor and increases the overall cost of the special structure. However, it is also known in the art according to patent 60 to produce liquid container for transporting milk as a container having a plurality of partitions for subdividing into a plurality of chambers. Such containers essentially do not have the aforementioned disadvantages, but they require considerable manufacturing overhead for serial production, which is uneconomical in small or medium series. "Above all, the insertion or insulation of partitions is complicated in terms of time and material. Another disadvantage is when damage due to violence or wear occur and the repair can only be done by an exchange.

Object of the invention

The invention has the goal of creating a continuous insulation effect in existing containers of several individual tanks, whereby labor and material can be saved and an increase in the container volume is achieved with dimensionally constant transport.

Essence of the invention

The essence of the invention is to achieve the continuous Isoliereffekt by appropriate training and preparation of the individual boiler enclosing insulation and the arrangement of the individual boiler with each other and their attachment "with less effort in technical resources and investments.

Features of the invention

The features of the invention are that a container made of individual kettles is insulated technology as a closed whole. The opposite end faces of two adjacent boiler are formed without insulating layer and have a support ring, one end of which is connected to the free leg of the outer layer and with its other end to the inner layer. "The stiffened with the support ring leg two adjacent boiler are coaxial with each other arranged a small distance by an elastic profile is used, which acts simultaneously insulating. Each provided with a dome boiler has laminated metal parts in the lower part of the boiler assembly to which the boiler associated with vehicle frame and tolerance compensating support elements are assigned * The tanks have in the container longitudinal axis on the one hand a tubular insulating layer or on the other hand, a front not comprehensive Uniform insulating layer. In this case, the open side of the insulating layer in the region of the end face between outer and inner layer is closed by a support ring of different shape. While

the free legs of the boiler in the container longitudinal axis projecting the end faces, they are formed in Porm and spaced from each other an elastic profile receiving. In this case, the distance between the coaxially arranged leg is formed in relation to the distance of the adjacent end faces as a minimum distance * For attachment of the boiler, a support element is bent and provided in three levels tolerance-compensating «

The invention will be explained in more detail below with reference to an exemplary embodiment. In the accompanying drawings show:

The embodiment according to FIG. 1 and FIG. 2 shows a container with four vessels 1 arranged in the longitudinal direction; 2; 3; 4 made of plastic material · Each boiler 1; 2; 3; 4 forms a self-contained unit and consists of various plastic materials, which include an insulating layer 5. The insulating layer 5 is bounded by an inner layer 6, which consists of a liner ™ and a GUP layer, and an outer layer 7 made of plastic material and each surrounds a vessel 1; 2; 3; 4 only partially. This is done in such a way that a boiler 1; 2; 3 »4 is not equipped with the insulating layer 5 at least on one of its end faces 8. For more than two longitudinally arranged boilers 1; 2; 3; 4, eg four boilers according to embodiment _s are both end faces 8 of the adjacent boilers 2; 3 without insulating layer 5. For complete enclosure of the insulating layer 5, therefore, a support ring made of plastic material is provided. This support ring 9 is provided with one end 10 with the free leg 11 of the outer layer 7 and

- \ ~; 6 - 2 2 5.5 0 4

and connected to the other end 12 with the inner layer 6. At the same time the free leg 11 of the outer layer 7 is stiffened and stabilized with the support ring 9. The boiler 1 thus produced separately; 2; 3; 4 with a partial insulating layer 5 can be queued up in any number and choice. It is important that the stiffened with the support ring 9 leg 11 of two adjacent boiler 1; 2 or 2; 3 or 3; 4 to each other coaxially and are arranged at a small distance, so that the end faces 8 to each other have a small distance. The necessary for tolerance compensation distance between the legs 11 to each other is compensated by means of elastic profile 13. In Fig. 3 to 5, some embodiments of the support ring 9 and the elastic profile 13 are shown. Characteristic of this again is the small distance of the end faces 8 to each other and the relatively large coverage of the legs 11 through the profile 13 * The facing end faces 8 are almost without insulation 5. The insulating effect is achieved with the profile 13 in conjunction with support ring 9 and the Ends 11 of the outer layer 7. Therefore, thermally, the juxtaposition of boilers 1; 2; 3; 4 to be considered as a continuous container with two outdoor floors. Such manufactured and lined boiler 1; 2; 3; 4 can be provided in the same way as usual constructions with a dome 14 as Einfüllöff- - opening or similarly as an outlet opening, as shown in Fig. "Thereafter, the dome 14 for receiving the dome cover z. B. designed as a compact dome and welded to the inner layer 6 at the seam 15. Due to the outer layer 7, the dome 14 is additionally reinforced. The welding of the dome 14 is carried out with the liner of the inner layer 6 only after its lamination "In conjunction with the juxtaposition of such boiler 1; 2; 3; to a isolated technical closed container attachment is of particular importance. These are, on the boilers 1; 2; 3; 4 force e _v inle it ungspunkt e 16, whereby the attachment can take place at vehicle frame 17 or the like as shown in FIG. 8 and FIG. 9 show. For this purpose, there are the force application points 16 of metal parts 18, which with tolerance-compensating
