Abstract

A moulded plastic container with a handle formed by creating an aperture so that the opposite walls of the container are fused together around the periphery of the container is formed by introducing an extruded plastic tube into a moulding cavity produced between two half moulds each of which has an aligned hole in its outer side wall. The holes are blocked by plugs mounted on a rotatable support and the container is blow moulded in the moulding cavity. The support is then moved to remove the plugs from two holes and the support rotated to insert formers into the holes. The formers push the side walls of the container together and produce the aperture which creates the handle. The container is pref. used as a water container. The container is produced in continues operation and eliminates a pre-blow moulding process in a separate mould before forming the handle.

Die Erfindung betrifft eine Vorrichtung zum Herstellen eines einen Griff aufweisenden, aus thermoplastischem Kunststoff bestehenden Behälters, bei dem die Durchgrifföffnung zwei einander gegenüberliegende Behälterwände miteinander verbindet, mit einer Einrichtung zum Herstellen eines schlauchförmigen Vorformlings und mit einer im wesentlichen zwei Formhälften aufweisenden, geteilten, vorzugsweise kühlbaren Blasform, ferner mit dem Herstellen der vom Griff umschlossenen Aussparung dienenden Formteilen in Gestalt von Kernen, die in den Innenraum der Blasform von beiden Seiten der Aussparung her ein- und ausfahrbar sind, und deren jeder in einem aus der Blasform gebildeten Führungskanal verschiebbar ist, und ferner mit in den Führungskanälen ein- und ausfahrbaren Stopfen, die die Kanäle an ihren inneren Enden verschließen und mit einem beidseits der Schließebene der Blasform und wenigstens angenähert parallel zu dieser angeordneten Drehteller zum Tragen der Stopfen und der Kerne, und mit einem Antrieb für den Drehteller zu dessen schrittweisem Verdrehen, nach Patent 24 56 723. The invention relates to an apparatus for producing a Handle having, made of thermoplastic material container, at which the passage opening two opposing container walls with each other connects, with a device for producing a tubular preform and with a divided, preferably one, having essentially two mold halves coolable blow mold, also with the production of the recess enclosed by the handle serving molded parts in the form of cores, which are in the interior of the blow mold of both sides of the recess can be retracted and extended, and each of them in one The guide channel formed from the blow mold is displaceable, and furthermore with in the Guide channels retractable and retractable plugs, which the channels at their inner ends close and with one on both sides of the closing plane of the blow mold and at least approximately parallel to this arranged turntable for carrying the stopper and the cores, and with a drive for the turntable for its gradual rotation, according to patent 24 56 723. Der Erfindung liegt die Aufgabe zugrunde, diese Vorrichtung zu vereinfachen. The invention is based on the object of simplifying this device. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Stopfen frei von jeglicher Aufheizvorrichtung sind. This object is achieved according to the invention in that the stopper are free from any heating device. Die Erfinder haben nämlich erkannt, daß die gemäß der Haupterfindung vorgeschlagenen Stopfen, die zum Ein- und Ausfahren in Führungskanäle in den Blasformhälften vorgesehen sind, nicht notwendigerweise aufheizbar sein müssen und daher frei von jeglicher besonderer Vorrichtung sein können. Ist nämlich zB. Namely, the inventors have recognized that according to the main invention proposed stopper, which is used for moving in and out in guide channels in the blow mold halves are provided, do not necessarily have to be heatable and therefore free from can be any special device. Is for example. die Wandstärke des eben extrudierten Vorformlings groß genug, so verbleibt dieser in jenen Wandbereichen, aus denen der Griff gebildet wird, unter Umständen noch genügend warm, so daß diese Wandbereiche auch ohne Aufheizung und trotz Kühlung der übrigen Blasform zum Griff verformt werden können.the wall thickness of the preform just extruded is large enough so that it remains this in those wall areas from which the handle is formed, under certain circumstances still warm enough so that these wall areas too without heating and despite cooling the rest of the blow mold can be deformed to the handle. Es wird im Rahmen dieser Zusatzanmeldung für die hier beanspruchte Merkmalskombination nur in deren Gesamtheit Schutz beansprucht, also nicht für Unterkombinationen. It is claimed in the context of this additional application for the one here Combination of features only claimed protection in their entirety, i.e. not for sub-combinations. Die Erfindung ist an Hand der Zeichnung näher erläutert. Darin zeigt Fig. 1 Draufsicht auf die eine Formhälfte einer Blasform, und zwar in deren Hohlraum hinein, F i g. 2 bis 5 Querschnitte in Schnittansicht A-A durch beide Formhälften derselben Blasform in verschiedenen Arbeitsphasen, F i g. 6 bis 8 Querschnitte durch eine Ausstanzvorrichtung in verschiedenen Arbeitsphasen, und F i g. 9 und 10 einen Drehteller in Seitenansicht (Fig. 9) und in einer Draufsicht von unten (F i g. 10). The invention is explained in more detail with reference to the drawing. In it shows Fig. 1 plan view of one mold half of a blow mold, namely in the cavity inside, Fig. 2 to 5 cross-sections in sectional view A-A through both mold halves the same blow mold in different work phases, F i g. 6 to 8 cross sections through a punching device in different working phases, and FIG. 9 and 10 one Turntable in side view (Fig. 9) and in a plan view from below (Fig. 10). Die Blasform dient dem Blasen einer Haushalts-Griffflasche. Die dargestellte Formhälfte 1 weist dementsprechend eine Aussparung 3 zum Herstellen einer Grifföffnung der Flasche auf. Der Blasform ist ein Extruder zugeordnet, von dem hier nur die Austrittsdüse 4 gezeigt ist Der Extruder arbeitet senkrecht von oben nach unten und extrudiert einen hier nur gestrichelt dargestellten Schlauch 5. Die Blasform ist kühlbar. The blow mold is used to blow a household handle bottle. The shown Mold half 1 accordingly has a recess 3 for producing a handle opening the bottle open. An extruder is assigned to the blow mold, of which only the Exit nozzle 4 is shown. The extruder operates vertically from top to bottom and extrudes a hose 5, shown here only in dashed lines. The blow mold can be cooled. F i g. 2 zeigt die Blasform in geöffnetem Zustand, wobei auch die zweite Formhälfte 2 dargestellt ist Der Schlauch 5 befindet sich in der Mitte zwischen diesen beiden Formhälften 1 und 2. Wie aus dieser Darstellung ersichtlich, hat die Aussparung 3 bei beiden Formhälften 1 und 2 die Gestalt eines durchgehenden Kanals. In die Kanäle ragt bereits je ein Stopfen 6 hinein. Beide Stopfen 6 haben an ihren dem Blasforminneren zugewandten Enden eine räumlich konvex ausgebildete Arbeitsfläche 7.F i g. 2 shows the blow mold in the open state, with the second mold half 2 is shown. The tube 5 is located in the middle between these two mold halves 1 and 2. As can be seen from this illustration, the Recess 3 in both mold halves 1 and 2 has the shape of a continuous channel. A plug 6 already protrudes into each of the channels. Both plugs 6 have on their the ends facing the blow mold interior a spatially convex working surface 7th Mit F i g. 3 ist die Blasform in geschlossenem Zustand gezeigt. Der Schlauch 5 ist nunmehr mittels einer nicht dargestellten Pinole so weit aufgeblasen, daß er überall außer im Bereich der Kanäle an der Innenwandung der Blasform anliegt. Die Stopfen 6 sind nunmehr noch weiter in die Kanäle eingefahren. In dieser ihrer Endstellung ragen ihre Enden mit den Arbeitsflächen 7 in den Innenraum der Blasform hinein, so daß das thermoplastische Material hier entsprechend eingebeult ist Auch erkennt man aus dieser Darstellung schon wesentliche Teile des einen der beiden Drehteller 10. With F i g. 3 shows the blow mold in the closed state. Of the Hose 5 is now inflated so far by means of a quill, not shown, that it rests against the inner wall of the blow mold everywhere except in the area of the channels. The plugs 6 have now moved even further into the channels. In this hers End position protrude their ends with the work surfaces 7 in the interior of the blow mold into it, so that the thermoplastic material is dented accordingly here too one can already see essential parts of one of the two from this representation Turntable 10. Dieser Drehteller 10 trägt nicht nur den Stopfen 6, sondern auch einen Kern 8.This turntable 10 carries not only the stopper 6, but also one Core 8. Bei der Darstellung von F i g. 4 ist die Blasform immer noch geschlossen. Doch sind nunmehr die Stopfen 6 ausgefahren und statt dessen die beiden Kerne 8 eingefahren. Die beiden Enden der Kerne 8 sind ganz dicht beieinander. Sie haben Material von beiden Seiten im Bereich der Aussparung zusammengeschoben. Der gesamte Bereich der Grifföffnung ist damit gebildet Bei der Darstellung gemäß Fig.5 sind die beiden Formhälften 1, 2 der Blasform wieder auseinandergefahren, so daß die nunmehr weitgehend fertiggebildete Griffflasche freigegeben ist. Die beiden Kerne 8 befinden sich noch in den Kanälen der Formhälften 1,2, werden aber im nächsten Augenblick völlig herausgezogen. In the illustration of FIG. 4 the blow mold is still closed. However, the plugs 6 are now extended and instead the two cores 8 retracted. The two ends of the cores 8 are very close to one another. They have Material pushed together from both sides in the area of the recess. The whole The area of the handle opening is thus formed. In the illustration according to FIG the two mold halves 1, 2 of the blow mold moved apart again so that the now largely finished handle tab is released. The two cores 8 are still in the channels of the mold halves 1,2, but will be in the next Moment completely pulled out.
