Abstract

The vacuum jug has a casing with a lower section (4) which overlaps the walls of its base (2). This is attached to it by laser welding, forming a water-tight connection.

Description

Die Erfindung betrifft eine Isolierkanne oder einen Warmhaltebehälter aus Kunststoff mit einem isoliertem Glaskolben bzw. einem eingeschäumten Flüssigkeitsbehälter. Isoliergefäße aus Kunststoff heute üblicher Machart, werden meist mit einem Schraubboden zusammengefügt. In diese Isoliergefäße kann beim Reinigen sehr leicht Wasser eindringen. Um diese Art von Isoliergefäße spülmaschinenfest zu bekommen, werden Dichtringe eingebracht, welche durch einen zusätzlichen Montageschritt aufgebracht werden müssen Seit kurzem gibt es auch eine Lösung in welcher der Boden durch ein zusätzliches Aufspritzen von Kunststoff in die Zwischenräume von Boden und Körper abgedichtet wird. Ein solches Verfahren ist ebenfalls sehr aufwendig, da zu jeder Isolierbehälterform ein neues Werkzeug für die Dichtungsgeometrie erstellt werden muss. An der Verbindungsstelle vom Körper zum Boden muss das Werkzeug sehr genau an die Außenkontur angepasst sein. Dies führt bei der nachträglichen Entformung des Körpers aus dem Werkzeug oftmals zu Ziehriefen und Oberflächenkratzern.The The invention relates to an insulating jug or a holding container Plastic with an insulated glass bulb or a foamed liquid container. Insulated plastic containers today more common Machart, are usually joined together with a screw bottom. In these Insulating vessels can Water is very easy to penetrate when cleaning. To make this type of insulated containers dishwasher safe To get sealing rings are introduced, which by an additional Assembly step must be applied Recently, there is also one solution in which the soil by an additional spraying of plastic in the interstices of soil and body is sealed. Such a method is also very expensive, there to each Isolierbehälterform a new tool for the seal geometry must be created. At the junction from the body To the ground, the tool must be very precisely adapted to the outer contour. This leads the subsequent Removal of the body from the tool often to drawing grooves and surface scratches.

Da der im Isoliergefäß befindliche Glaskolben erhebliche Maßtoleranzen aufweist, ist außerdem immer eine Höhentoleranzüberbrückung für die Montage dieser Produkte vorzusehen. Dies ist in der Schraubbodenvariante sehr einfach zu gewährleisten, da die Gewindestücken eine Höhenüberbrückung von mehreren Millimetern zulassen. Die Problematik liegt hier in der sehr aufwendigen Werkzeugerstellung, da das Gewindesegment als Hinterschnitt im Werkzeug nur durch Schieber, Ausdrehkerne oder Einfaltkerne entformt werden kann.There located in the insulated vessel Flask significant dimensional tolerances is also always a height tolerance bypass for mounting to provide these products. This is in the Schraubbodenvariante very easy to ensure there the thread pieces a height bridging of allow several millimeters. The problem lies here in the very complex tooling because the thread segment as an undercut Molded out in the tool only by slides, boring cores or Einfaltkerne can be.

In der neuen Ausführungsform wird die Werkzeugherstellung wesentlich vereinfacht, da weder am Körper noch am Boden Gewindesegmente notwendig sind. Diese einfachere Werkzeugerstellung führt dann zu einem kostengünstigeren Werkzeug. Auch in den Fertigung der Kunststoffteile sind durch die nicht vorhandenen Gewindesegmente Einsparungen möglich, da die Wandstärken reduziert und so die Zykluszeiten der Kunststoffteile verringert werden kann.In the new embodiment Tool making is much easier because neither the body thread segments are still necessary on the ground. This easier tooling then leads at a lower cost Tool. Also in the production of the plastic parts are by the non-existent thread segments savings possible because the wall thicknesses reduced and so the cycle times of the plastic parts can be reduced.

Im neuen Montagevorgang wird der Boden in den vormontierten Körper gespannt und dann an der kompletten Außennaht per Laser verschweißt. Das Körpermaterial ist dabei laserlichtdurchlässig gestaltet bzw. mit laserdurchlässigem Farbbatch ausgerüstet. Der Boden wird durch den Laser erhitzt und verschweißt, so dass an der Kontaktstelle eine Schmelze entsteht, welche sich durch den Anpressdruck mit dem Körpermaterial verbindet.in the new assembly process, the floor is stretched in the preassembled body and then at the complete outside seam welded by laser. The body material is thereby transparent to laser light designed or laser-permeable Color batch equipped. The bottom is heated by the laser and welded, so that at the contact point, a melt is formed, which flows through the Contact pressure with the body material combines.

Der Boden wird dabei kräftig mit einer definierten Druckkraft vorgespannt, um die Längenschwankungen durch Relaxation und Temperaturunterschiede auszugleichen.Of the Soil becomes strong with a defined compressive force biased to the length variations compensate for relaxation and temperature differences.

Ein weiterer Vorteil dieser Konstruktion ist, dass das Spaltmaß zwischen Kunststoffkörper und Glaskolben reduziert werden kann, da bislang der Gewindeinnendurchmesser im Körper den Kolbenaussendurchmesser bedingt hat.One Another advantage of this design is that the gap between Plastic body and glass piston can be reduced, since so far the threaded internal diameter in the body has caused the piston outer diameter.

Dieser ist mit der neuen Ausführung nicht mehr notwendig. Dadurch kann der Behälter in den Aussenabmessungen reduziert werden.This is with the new version not necessary anymore. This allows the container in the external dimensions be reduced.
