Definitions

  • the present invention relates to an insulating container for receiving goods that are to be thermally protected.
  • Such a container as described in the preamble of claim 1 is known from the prior art.
  • the containers which are used in particular in the food industry, usually have a cuboid shape.
  • the side walls including the container door and floor and lid are formed by rigid components, such as plates made of plastic or metal.
  • a dimensionally stable trough for example of GRP, is placed inside the container walls, so that a space is formed between the container walls and the trough.
  • This is foamed with a thermosetting and insulating substance, so that the tub is thermally insulated from the container environment and at the same time held stationary and stabilized.
  • Object of the present invention is therefore to provide an insulated container, which is easier, faster and cheaper to produce than the known from the prior art predecessor.
  • the method for producing the container should also be improved accordingly.
  • the object is achieved by an insulated container according to claim 1 or a method according to claim 9.
  • the invention is based on the knowledge that the surfaces bounding the insulating foam body are at least partially realized by flexible means which are very thin-walled and flexible and thus have a low weight.
  • flexible outer walls By forming the container outer walls by means of such a flexible outer skin, the use of solid and dimensionally stable plate elements known from the prior art as side walls is unnecessary, to limit the later to be formed foam body in its spatial dimensions to the outside. Instead, some or all container outer walls are formed by the flexible outer skin (for example in the form of a PVC film).
  • a container-contour-shaping, preferably cuboid-shaped support structure serves as a support for the film, which can be stretched or -wowickelt around the support structure.
  • an insert element for example, the aforementioned trough made of GRP
  • the film can be attached not only "from the roll" to a variety of support structures - also your weight per area is significantly lower than that of the known stable side panels.
  • a possibly required stabilization of the flexible outer skin during foaming in the sense of the aforementioned formwork can be readily realized by support plates, which bear during the foaming temporarily from the outside to the flexible container outer walls formed by the film. This results in a stable formwork on the outside of the support structure, which can be completely removed after curing. To produce the next container, the same stabilizing plates or even a formwork body formed therefrom can be temporarily used again.
  • a significant advantage of the invention is that the outer skin formed of film can be stretched or wound over the support structure, so as to represent the outer contour of the container or its side surfaces easily and quickly.
  • the individual side wall elements from the inside each the frame construction created or fixed there which means considerably more effort than the strapping of the support structure with the flexible outer skin or film.
  • the strap allows the formation of several side walls in one operation, for example by the film with a width, for example, the container height, laterally wound around or on the support structure, whereby in a circulation around the support structure all four particular side surfaces of the container are formed, albeit in an initially labile or flexible form.
  • Another advantage is that the film actually completely covers each side surface of a container, in particular without cracks and crevices.
  • Such leaks avoids the inventive film or the method for their arrangement on the container, therefore, because the film extends during unwinding on the support structure over the entire clear width of a container side and the rods and struts of the support structure on their outwardly facing surfaces and sides or included.
  • the continuous stretched film therefore forms no cracks and gaps, which are to seal the foaming in the prior art, however, separate and expensive.
  • An embodiment of the insulating container according to the invention accordingly comprises a preferably cuboid support structure for the formation of some or all of the side edges of the container. Furthermore, an insert element is provided, which is arranged between container outer walls and forms an insulating volume with its inner side.
  • the container has a flexible outer skin, which is supported by the support structure and forms container outer walls, wherein a gap formed between the insert element and the container outer walls is foamed by a thermally insulating and hardening foam body.
  • At least one container outer wall or part thereof may be formed by a door.
  • the insert element which may for example have the shape of a tub, with its opening of the door opposite arranged in the container.
  • an insert element is a dimensionally stable pan whose interior determines the insulating volume. If necessary, such a trough can be stabilized by a suitable core during foaming in order to be able to withstand the pressure. As a dimensionally stable tub, this offers sufficient resistance against damage to the underlying foam body even during later operation of the container.
  • a particularly advantageous alternative embodiment of the insulating container according to the invention provides for the insert element to choose a flexibly deformable structure in the manner of a shell, in particular a PVC shell.
  • a flexible shell offers advantages similar to the flexibly designed outer skin of the container. It is inexpensive, lightweight and due to the flexible nature also almost arbitrarily shapeable, so that the shape of the insulated interior is easily and individually predetermined. Since the known from the prior art, dimensionally stable, heavy tub, through which the shape of the interior is substantially rigid, then can be omitted, reduce the cost of this tub and the final weight of the insulated container.
  • a core use which occupies substantially the desired insulating volume and with at least a portion of its surface, the film that is to limit the insulating volume, during foaming as formwork supported.
  • a core could protrude into the interior of the container circumscribed by the outer walls of the container through a recess in the outer wall of the container which constitutes the later door opening.
  • a closely fitting to the core film or shell as a flexible insert element defines the insulating volume, which should not be foamed.
  • a gap is formed according to the invention, which is to be chosen sufficiently large in coordination with the properties of the Ausbulummaterials.
  • the intermediate space is typically in the form of a trough whose wall thickness corresponds to the later insulating layer between the insulating volume and the container outer wall. For better removal of the core after foaming, this can be slightly conical Have side surfaces that diverge slightly towards the container door (through which the core is removed).
  • the stabilization of the outer, typically substantially planar container walls can be carried out in the manner already described by externally applied to the outer skin support plates, which prevent bulging of the outer skin or container wall during foaming.
  • the container according to the invention with flexible outer skin and flexible insert element advantageously dispenses with the installation of rigid and heavy plate elements or trays as side part elements. Instead, the flexible film itself forms the interface with the foam body during foaming.
  • the formwork required for foaming are formed by support means to be arranged temporarily (stabilizing plates on the outside of the container or core in the interior of the container), which enable the subsequent foaming of the intermediate space remaining between the formwork elements to be dimensionally accurate.
  • the container Since the aids supporting the films can be removed again after curing, the container then consists essentially only of the foam body itself, the thin-walled film on the outside and inside and the support structure.
  • the support structure can run along the outer edges of the container in order to protect the foam body at these zones especially from damage.
  • the attachment of the container door to the support structure is also conceivable.
  • insert element is to be understood as the material or structure which limits the insulating volume to the outside.
  • An insert element may be a rigid structure such as a stable pan of FRP.
  • an insert element may also be a flexible, volume-shaped film which is initially unstable in itself.
  • An insert element can be stabilized on one side by a core for the purpose of foaming.
  • Isolier before that on the Foam body facing side of the insert member and / or the outer skin reinforcing means are arranged to protect the foam body there against unwanted deformation or damage.
  • These may be plastic plates or angle profiles, which are arranged in front of the foaming at the vulnerable points (eg in the area of the container outer edges or also below or laterally of the insulating volume in the intermediate space) in order to firmly integrate them in the context of foaming or in the To integrate foam body. Conveniently, they form an interface with the film immediately adjacent, in order to be able to directly resist a damage force beyond the film, ie from the container interior or from outside the container.
  • Another important advantage of the insulating container according to the invention is that a simple shaping of the insulating volume and / or the container outer wall is possible by the use of a flexible outer skin and in particular by the use of a flexible insert element.
  • profiling such as insertion grooves, stops, depressions or the like.
  • the insulating container according to the invention with its support structure and / or the cured foam body is releasably connectable to a mobile undercarriage.
  • the container is placed on a roll plate and movable with this, which advantageously extends the capabilities of the container.
  • the significant weight savings of the container due to the flexible outer skin or the flexible insert element also has an effect on the dimensioning of the mobile undercarriage, which in turn material and costs can be saved.
  • FIG. 1 shows an insulating container 1. This comprises a cuboid support structure in the form of a metallic tube frame 2.
  • the tube frame 2 essentially determines the outer dimensions of the container first
  • an insert member 3 is arranged, which has the shape of a trough with slightly conical side surfaces.
  • the insert element 3 opens towards a front side of the container 1 and defines with its interior an insulating volume 5.
  • the support structure 2 is covered with a flexible outer skin 6, whereby container outer surfaces 4 are defined (s. Fig. 3a, 3b ). Between the container outer surfaces 4 and the insert element 3 thereby creates a gap 7 in the form of a gap which surrounds the insert element on five sides.
  • the insert element 3 is stabilized on the one hand in its position or shape, on the other hand, the interior of the insert element is thermally insulated from the container environment.
  • the opening of the insert element to the door is closed by just this door 4 ', which is suitable for insulating, as in Fig. 2 shown.
  • Fig. 1 When foaming is expediently in Fig. 1 not shown core disposed inside the insert element 3, which corresponds to the size and shape of the desired isolation volume.
  • the insert formed by a flexible film adapts to this core and takes over during and after the curing of the foam body, the complementary shape to the core.
  • a stabilization of the formed by a flexible film container outer walls 4 for example by externally applied to the container outer wall stabilizing plates that stabilize the outer films 6 during foaming in their preferably planar shape.
  • the foam body 8 may also undergo a special functional shaping, e.g. Insertion grooves 10, recessed grips, stops, gutters or the like.
  • the front of the container 1 and the insert element 3 is closed by a door 4 '.
  • the door 4 ' on its inside and outside also on a flexible skin, wherein the intermediate gap is also formed by a thermosetting foam body.
  • a conventional rigid container door is conceivable, wherein the door is preferably attached to the support structure 2 and can be locked with it.
  • the container 1 rests on a rolling plate 9, with which it is flexibly movable.
  • the container 1 is detachably connected to the roller plate 9, so that it can be placed stationary if necessary.
  • Fig. 3 shows the rear, lower portion of the container 1 in detail.
  • the container outer surface 4 in the form of the film 6 stretched over the support structure 2.
  • a hidden by the film 6 gap 7 between the insert element and the film 6 may already be filled with a cured foam body, so that Fig. 3a shows the container in its final cured state.
  • Fig. 3b In contrast, the outer wall 4 and the film 6 is removed, so that the insert element 3 can be seen in the interior of the support structure 2 before foaming.
  • the aforementioned gap 7 serves asurgeonMinender gap, whereby the interior of the insert element 3 is thermally insulated from the environment of the container beyond the outer skin 4.
