Description

Verfahren zur Herstellung von einseitig offenen Isolierbehältern aus Schaumkunststoffen In einem älteren Patent ist die Herstellung von einseitig offenen Isolierbehältern aus Schaumkunststoffen mit unter Verwendung von Polymerisationsharzschichten gebildeten harten Oberflächen beschrieben. Hierbei werden in einer Form mit herausnehmbarem Kern an den Oberflächen von Form und Kern Polymerisationsharzschichten aufgebracht und vor deren Abbindung der Hohlraum zwischen Form und Kern mit Schaumkunststoffen aufgefüllt und anschließend während der Erhitzung der letzteren eine Abbindung der Harzschichten unter gleichzeitiger Erhärtung der an die Harzschichten grenzenden Randschichten der Schaumkunststoffe bewirkt.Process for the production of insulating containers open on one side Foamed plastics In an older patent is the manufacture of one-sided open Insulating containers made of foamed plastics with the use of polymerisation resin layers hard surfaces formed. This will be in a form with removable Core applied to the surfaces of the mold and core polymerisation resin layers and before they are set, the cavity between the mold and the core with foam plastics filled up and then a setting of the latter during the heating of the latter Resin layers with simultaneous hardening of those adjoining the resin layers Causes edge layers of the foamed plastics.

Demgegenüber besteht die Erfindung darin, daß flüssige Polymerisationsharze durch Eingießen, Einsaugen, Eindrücken od. dgl. zwischen Form und Kern eingebracht werden, wobei entweder die Harzmassen nach ihrer durch Erwärmen oder chemische Beeinflussung od. dgl. bewirkten Polymerisation einen Behälter ergeben, der nachträglich eine sich mit ihm verbindende Schaumkunststoff-Innenwand erhält, oder der zuvor fertiggestellte Schaumkunststoff-Hohlkörper selbst den Kern bildet, mit dessen Außenseite sich die in die Form eingebrachten Harzmassen verbinden. In contrast, the invention consists in that liquid polymerization resins by pouring, sucking in, pressing in or the like. Introduced between the mold and the core be, with either the resin masses after them by heating or chemical manipulation Od. The like. Effected polymerization result in a container that is subsequently a with it connecting foam plastic inner wall receives, or the previously completed Foam plastic hollow body itself forms the core, with the outside of which the connect resin masses introduced into the mold.

Dabei ist es ferner neu, daß der mit einer Außenwand aus Polymerisationsharzen versehene Schaumkunststoff-Hohlkörper auch an seiner Innenseite mit Polymerisationsharzen überzogen wird, die zwischen ihm und einem eingesetzten zweiten Kern in flüssigem Zustand eingebracht werden. It is also new that the one with an outer wall made of polymerization resins Foam plastic hollow bodies provided with polymerisation resins also on the inside is coated between him and an inserted second core in liquid State to be introduced.

Durch die Erfindung wird die Herstellung der einseitig offenen Isolierbehälter aus Schaumkunststoffen vereinfacht und verbilligt. Auch ist eine schnellere Herstellung möglich. Schließlich wird eine gute Ver- bindung zwischen der Schaumkunststoff-Innenwand und den Außenschichten erreicht. The invention enables the manufacture of the insulated container which is open on one side made of foam plastics simplified and cheaper. It is also faster to manufacture possible. After all, a good bond between the foam plastic inner wall and reached the outer layers.

In der Zeichnung sind verschiedene Wege für die Herstellung eines Schaumkunststoff-Hohlkörpers mit Oberflächen aus Polymerisationsharzen veranschaulicht, und zwar zeigt Abb. I schematisch einen Schnitt durch die Form und den Kern zur Herstellung eines Behälters aus Polymerisationsharzen vor Einführung der Harzmassen, Abb. 2 einen schematischen Schnitt durch eine Form zur Aufbringung einer Polymerisationsharzschicht auf der Außenseite eines zuvor fertiggestellten Schaumkunststoff-Hohlkörpers, der dabei den Kern bildet, Abb. 3 eine Vorrichtung zur Aufbringung einer Polymerisationsharzschicht auf der Innenseite eines zuvor fertiggestellten und mit einer Außenwand aus Polymerisationsharzen versehenen Schaumkunststoff-Hohlkörpers. In the drawing are different ways of making a Foam plastic hollow body with surfaces made of polymerisation resins illustrates namely Fig. I shows schematically a section through the mold and the core for Production of a container from polymerisation resins before the resin masses are introduced, Fig. 2 is a schematic section through a mold for applying a polymerisation resin layer on the outside of a previously finished foam plastic hollow body, the thereby forming the core, Fig. 3 a device for applying a polymerisation resin layer on the inside of a previously finished and with an outer wall made of polymerization resins provided foam plastic hollow body.

In Abb. I ist gezeigt, daß in die Form 1, die beispielsweise aus Blech oder anderem festem Werkstoff bestehen kann, ein Kern 2 eingesetzt ist, der beispielsweise zugleich mit seinem Rand 3 den Deckel der Form bildet. Zwischen Form 1 und Kern 2, der beispielsweise gegebenenfalls ebenfalls lediglich durch Blechwände gebildet werden kann, ist ein Zwischenraum 4 frei gelassen. Der Zwischenraum 4 wird nun erfindungsgemäß durch flüssige Polymerisationsharze ausgefüllt. Dies kann durch physikalische Beeinflussung der Harzmasse geschehen, beispielsweise durch Eingießen, Einsaugen, Eindrücken. Nach der Polymerisation der Harze, was beispielsweise mittels Erwärmung, chemischer Beeinflussung od. dgl. erfolgen kann, wird ein der Form angepaßter und nach Entfernung des Kerns oben offener Behälter 9 geschaffen. In Fig. I it is shown that in the form 1, which for example from Sheet metal or other solid material can exist, a core 2 is used, which for example, at the same time with its edge 3 forms the lid of the mold. Between form 1 and core 2, which, for example, may also only be provided by sheet metal walls can be formed, a gap 4 is left free. The gap 4 becomes now filled according to the invention by liquid polymerization resins. This can be done by physical influencing of the resin mass happen, for example by pouring, Suck in, push in. After the resins have polymerized, for example by means of Heating, chemical influence or the like. Can take place, is adapted to the shape and after removal of the core created container 9 open at the top.

Der Behälter 9 erhält nachträglich eine sich mit ihm verbindende Schaumkunststoff-Innenwand 5. The container 9 is subsequently given a connecting device Foam inner wall 5.

Statt dessen kann, wie in Abb. 2 gezeigt, der zuvor fertiggestellte Schaumkunststoff-Hohlkörper 5 selbst den Kern bilden, auf dessen Außenseite der Behälter g aufgebracht wird, wobei der Kern 5 unmittelbar an einem Deckel 6 angebracht sein kann. Der Kern 5 verbindet sich mit den Harzmassen 9 während der Einfüllung derselben in die Form.Instead, as shown in Fig. 2, the previously completed Foam plastic hollow body 5 itself form the core, on the outside of which Container g is applied, the core 5 being attached directly to a cover 6 can be. The core 5 combines with the resin mass 9 during filling same in the form.

Die Einführung der Harzmassen in die Form erfolgt beispielsweise durch Öffnungen 7 der Form unter Druck, wobei durch Öffnungen 8 die Luft entweichen kann. The resin compositions are introduced into the mold, for example through openings 7 of the mold under pressure, the air escaping through openings 8 can.

Gemäß Abb. 3 ist in den mit einer Außenwand g aus Polymerisationsharzen versehenen Schaumkunststoff-Hohlkörper5 ein Kern 10 eingesetzt, der beispielsweise mit einem Deckel II versehen ist. Zwischen dem Kern IO und dem Schaumkunststoff-Hohlkörper 5 ist ein schmaler Zwischenraum 12 frei gelassen, der beispielsweise durch die Öffnung 13 des Deckels mit Polymerisationsharzen gefüllt wird. Die Polymerisationsharzschichten zur Herstellung der Außen- und Innenwandung des Schaumkunststoff - Hohlkörpers können verhältnismäßig dünn ausgebildet werden. According to Fig. 3 is in the with an outer wall g made of polymerization resins provided foam plastic hollow body 5 a core 10 is used, for example is provided with a lid II. Between the core IO and the foam plastic hollow body 5 a narrow gap 12 is left free, for example through the opening 13 of the lid is filled with polymerization resins. The polymerization resin layers to produce the outer and inner walls of the foam plastic - hollow body can are made relatively thin.

Sie sind nach der Herstellung hart. Als Polymerisationsharz (Polyester) kann beispielsweise das auf dem Markt befindliche Marko-Harz Verwendung finden. Für die Schaumkunststoffe kann das auf dem Markt befindliche Hochpolymer, das unter dem Namen Moltopren auf dem Markt ist, verwendet werden.They are tough after manufacturing. As a polymerisation resin (polyester) For example, the Marko resin on the market can be used. For the foamed plastics, the high polymer available on the market, which is available under called Moltopren is on the market.
