Abstract

This new method manufactures multilayer insulating containers in plastic. It is new in that the construction of the individual layers, of which there are at least three, is effected from inside, outwards. Preferably, the plastic inner body is made first. This may be multilayered, and prepared conventionally. Foam is applied externally, using a known foaming process, to a defined thickness. Two outer shells are made, using conventional techniques. These are placed around the intermediate product, and joined by any suitable means, to form the outer body and surface of the insulating container. The container (also claimed) resists microwaves and impacts, protecting the goods to be stored. The forms are optional, and the useful volume forms a large proportion of the external volume.

Description

Es ist bekannt, daß evakuierte Hohlkörper sehr gute Isolationseigenschaften besitzen. Die gute Isolationswirkung des Vakuums wird z. B. bei Thermopenfenstern im Bauwesen bereits erfolgreich zur Wärmeisolierung von Gebäuden eingesetzt. Des weiteren ist bekannt, daß Kunststoffschäume ebenfalls sehr gute Isolationseigenschaften besitzen und ebenfalls z. B. in Form von Wärme­ dämmplatten im Bauwesen oder in Form von Isolationsschichten in Kühlschränken heute zum Stand der Technik zur Wärmeisolation zählen. Weiterhin ist bekannt, daß z. B. bei Haushaltsgeräten in Verbindung mit Isolationsbehältern gleichzeitig eine optisch und haptisch ansprechende Oberfläche und geeignete Medienbeständigkeit gefordert wird die eine zusätzliche Schicht um den eigentlichen Isolierkörper erfordert.It is known that evacuated hollow bodies have very good insulation properties. The good Isolation effect of the vacuum is such. B. already successful in thermopen windows in construction used for thermal insulation of buildings. Furthermore, it is known that plastic foams also have very good insulation properties and also z. B. in the form of heat insulation boards in construction or in the form of insulation layers in refrigerators to the stand today technology for thermal insulation. It is also known that, for. B. in household appliances in Connection with insulation containers at the same time a visually and haptically appealing surface and suitable media resistance is required the one additional layer around the actual one Insulator requires.

Die gute Isolationswirkung des Vakuums wird auch bei Isolationsbehältern ausgenutzt. Bei verschiedenen Anwendung der Vakuumisolation, wie z. B. bei Thermoskannen, werden sogenannte Vakuumglaskörper zur Isolation eingesetzt. Darunter versteht man Hohlkörper aus Glas, deren Hohlraum evakuiert ist. Die geometrische Gestaltungsfreiheit bei der Konstruktion solcher Vakuum­ glaskörper ist aufgrund der hohen mechanischen Belastung des Glases durch das Vakuum allerdings begrenzt. So können gebrauchsfähige Vakuumglaskörper nur unter der Voraussetzung hergestellt werden, daß sie in erster Näherung eine kugelförmige bzw. zylinderförmige Kontur besitzen. Ein weiterer Nachteil solcher Vakuumglaskörper liegt darin, daß sie unter mechanischer Einwirkung von außen leicht zerbrechen und somit anfällig gegen Stöße sind. Auch ist die Mikrowellentauglichkeit von Isolationsbehältern mit Vakuumglaskörpern aufgrund der Verspiegelung der Innenseite des Vakuumglaskörpers, die zur Minimierung der Wärmeverluste durch Wärmestrahlung notwendig ist, nicht gegeben. Weiterhin ist die Designfreiheit der umgebenden Außenschicht bei der Konstruktion von Isolationsbehältern, bei denen die Isolationswirkung durch einen Vakuumglaskörper erreicht wird, aufgrund der weitgehend festgelegten kugelförmigen bzw. elipsoiden Kontur des Isolations­ behälters, die zur Gewährleistung der Stabilität unabdingbar sind, stark eingeschränkt bzw. mit großen Raumverlusten hinsichtlich des Verhältnisses von Außenkontur zum Nutzvolumen verbunden.The good insulation effect of the vacuum is also used for insulation containers. At various applications of vacuum insulation, such as B. in thermos, so-called Vacuum glass body used for insulation. This is understood to mean hollow bodies made of glass, their Cavity is evacuated. The geometric design freedom in the construction of such a vacuum glass body is due to the high mechanical stress on the glass from the vacuum limited. So usable vacuum glass bodies can only be produced under the condition that they have a spherical or cylindrical contour in the first approximation. A Another disadvantage of such vacuum glass bodies is that they are under the mechanical influence of break easily on the outside and are therefore prone to impact. It is also suitable for microwaves of insulated containers with vacuum glass bodies due to the mirroring of the inside of the Vacuum glass body, which is necessary to minimize the heat losses through heat radiation, not given. Furthermore, there is freedom of design for the surrounding outer layer during construction of insulation containers in which the insulation effect is achieved by a vacuum glass body is due to the largely defined spherical or ellipsoidal contour of the insulation container, which are essential to ensure stability, severely restricted or with large space losses in relation to the ratio of the outer contour to the usable volume connected.

Das in dieser Patentschrift beschriebene Verfahren ermöglicht die Herstellung von Isolations­ behältern, bei denen die gute Isolationswirkung von Kunststoffschäumen für die Isolierung ausgenutzt wird und bei denen die mit den Vakuumglaskörpern verbundenen Nachteile nicht auftreten. Gleichzeitig gewährleistet das Verfahren eine ansprechende Oberflächenqualität der Formteile, wobei sich für die Oberflächenschicht gleichzeitig eine Struktur erreichen läßt, die gut und wiederholt gereinigt werden kann und medienbeständig für Anwendungen z. B. im Bereich des Haushalts ist.The method described in this patent enables the production of insulation containers in which the good insulation effect of plastic foams for insulation is exploited and in which the disadvantages associated with the vacuum glass bodies are not occur. At the same time, the process ensures an appealing surface quality Molded parts, whereby a structure can be achieved for the surface layer that is good and can be cleaned repeatedly and media-resistant for applications such. B. in the area of Is household.

Durch ein Verfahren mit den Merkmalen des Anspruchs I können Isolationsbehälter hergestellt werden, die einen mindestens dreischichtigen Aufbau besitzen. Dieser Aufbau besteht mindestens aus einer geeignet beständigen inneren Schicht zur Aufnahme des zu verwahrenden Gutes, einer mittleren Schicht zur Isolation und/oder auch Stoßfestigkeit des Isolationsbehälters sowie einer äußeren Schicht, durch die eine ansprechende Oberflächenqualität und eine geeignete Beständigkeit gegen Belastungen, wie sie z. B. im Haushalt durch Reinigen auftreten, erreicht wird. Alle diesen Schichten bestehen aus Kunststoff oder Kunststoffschaum, wobei die innere und die äußere Schicht mehrschichtig aufgebaut und eventuell mit anderen Materialien beschichtet sein können. Ge­ schlossen wird der Isolationsbehälter durch einen geeigneten Deckel.Isolation containers can be produced by a method having the features of claim I. that have an at least three-layer structure. This structure exists at least from a suitably stable inner layer to hold the goods to be kept, one  middle layer for insulation and / or shock resistance of the insulation container and a outer layer, through which an attractive surface quality and a suitable resistance against loads such as z. B. occur in the household by cleaning is achieved. All of these Layers are made of plastic or plastic foam, with the inner and outer layers built up in multiple layers and possibly coated with other materials.
