Abstract

Jugs made of fragile material are provided with a plastic mouth edge to reduce the susceptibility to breakage. For cost reasons, the jug handle is then connected to the plastic edge. The connection between the plastic edge and the jug must accordingly be of very sturdy and precise construction since this connection can otherwise become detached during use. In the new hotel jug, the production costs are to be low and the attachment of the plastic edge is to be as simple and durable as possible. <??>In order to obtain a durable connection between the plastic edge of a jug, in particular a glass jug, and the handle of the jug, the plastic edge and the handle are attached separately from one another to the outside of the jug. The plastic edge and the handle are preferably made of different plastic materials and are correspondingly attached with different adhesives, it also being possible for the plastic edge to be mounted on the edge of the jug by simple engagement. <??>The hotel jug can be used, in particular, in the commercial sector, i.e. in restaurants and hotels. <IMAGE>

Description

Die Erfindung betrifft eine Kanne nach dem Oberbegriff des Anspruchs 1 und ein Verfahren zur Herstellung der Kanne.The invention relates to a jug according to the preamble of claim 1 and a method for producing the jug.

Kannen, insbesondere solche aus Glas, die als Servier- und Auffangbehälter für z.B. Kaffee verwendet werden, werden zur Verminderung der Bruchanfälligkeit beim Anstoßen mit einem Kunststoff-Mundrand versehen. Solche Kannen sind insbesondere im gewerblichen Bereich, u.a. im Gaststätten- und Hotelbetrieb, sehr verbreitet. Die Vorteile solcher Kannen sind die schon erwähnte geringe Bruchanfälligkeit und günstigere Gießeigenschaften, die durch den Kunststoff-Mundrand realisiert werden können.Pots, especially those made of glass, which serve as serving and collecting containers for e.g. Coffee are used are provided with a plastic mouth rim to reduce the susceptibility to breakage when toasting. Such cans are particularly useful in the commercial sector, including very common in restaurants and hotels. The advantages of such cans are the already mentioned low susceptibility to breakage and more favorable casting properties, which can be achieved through the plastic rim of the mouth.

Die Qualitätsanforderungen an solche Kannen sind gerade im gewerblichen Einsatz sehr hoch. Trotzdem müssen - um konkurrenzfähig zu bleiben - die Herstellungskosten niedrig liegen. Um diesen Anforderungen zu genügen, haben bekannte Kannen einen mehr oder weniger hochgezogenen Glashals, auf dem der Kunststoffrand - meist bajonettartig - klemmend aufsitzt. Eine weitere Sicherung des Kunststoffrandes kann mittels Dichtringen und/oder Klebstoffen zwischen dem Kunststoffrand und dem Glasrand erfolgen. Mit dem Kunststoffrand ist einstückig oder mehrstückig der Tragegriff der Kanne verbunden. Die einstückige Verbindung ist dabei bevorzugt, da sie besonders kostengünstig ist. Kannen dieser Bauart werden beschrieben in den US-PS'en 3,632,025, 4,090,648 und 4,140,251 sowie in der DE-OS 31 31 724.The quality requirements for such cans are very high, especially in commercial use. Nevertheless, in order to remain competitive, the manufacturing costs must be low. In order to meet these requirements, well-known cans have a more or less raised glass neck, on which the plastic edge - usually bayonet-like - sits tightly. The plastic edge can be further secured by means of sealing rings and / or adhesives between the plastic edge and the glass edge. The handle of the jug is connected in one piece or in several pieces to the plastic edge. The one-piece connection is preferred because it is particularly inexpensive. Cans of this type are described in US Pat. Nos. 3,632,025, 4,090,648 and 4,140,251 and in DE-OS 31 31 724.

Bei den Kannen der beschriebenen Art zeigte es sich, daß ein langer und präzise gefertigter Kannenhals notwendig ist, um den Kunststoffrand sicher zu verankern. Dies erhöht jedoch die Fertigungskosten. Als problematisch erwies sich auch die Klebeverbindung zwischen dem Kunststoffrand und dem Glasrand, da diese Klebeverbindung nicht elastisch genug ist und im Gebrauch, insbesondere durch das Spülen, zum Verspröden neigt. Zudem muß die Verbindungsstelle die gesamte Belastung beim Hantieren mit einer gefüllten Kanne aufnehmen. Die Summe dieser Beanspruchungen führte häufig zu Schäden infolge des Lösens der Verbindungsstelle.In the cans of the type described, it was found that a long and precisely manufactured can neck is necessary in order to securely anchor the plastic edge. However, this increases manufacturing costs. The adhesive connection between the plastic edge and the glass edge also proved to be problematic, since this adhesive connection is not elastic enough and tends to become brittle in use, in particular due to rinsing. In addition, the connection point must absorb the entire load when handling a filled jug. The sum of these stresses often resulted in damage from loosening the joint.

Der Erfindung liegt die Aufgabe zugrunde, eine Kanne, insbesondere aus Glas, Keramik, Glaskeramik, Porzellan oder anderem zerbrechlichen Material, mit einem als Ausguß dienenden Kunststoffrand und einem Griff zur Verfügung zu stellen, wobei die Fertigungskosten der Kanne niedrig und die Herstellung einfach sein sollen. Auch die Befestigung des Kunststoffrandes soll einfach und dauerhaft möglich sein.The invention has for its object to provide a jug, in particular made of glass, ceramic, glass ceramic, porcelain or other fragile material, with a plastic rim serving as a spout and a handle, the manufacturing costs of the jug should be low and the manufacture should be simple . The attachment of the plastic edge should also be easy and permanent.

Diese Aufgabe wird bei einer gattungsgemäßen Einrichtung durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is achieved in a generic device by the characterizing features of claim 1.

Es hat sich gezeigt, daß die aus dem Stand der Technik bekannte Befestigung des Griffes am Kunststoffrand bezüglich der Montage und Montagekosten zwar einfach und kostengünstig sein kann, daß jedoch ein an der Außenseite der Kanne getrennt von dem Kunststoffrand angebrachter Griff aus anderer Sicht vorteilhafter ist. Die Trennung von Kunststoffrand und Griff sowie deren Befestigungsstellen erlaubt es, unterschiedliche Materialien für beide Teile und entsprechend auch unterschiedliche Befestigungsmittel zu verwenden.It has been shown that the fastening of the handle to the plastic edge known from the prior art can be simple and inexpensive in terms of assembly and assembly costs, but that a handle attached to the outside of the can separately from the plastic edge is more advantageous from another point of view. The separation of the plastic edge and handle as well as their fastening points allows different materials to be used for both parts and, accordingly, different fastening means.

So kann z.B. der Kunststoffrand entsprechend dem Stand der Technik aus Polypropylen gefertigt und mittels eines Polyamid-Schmelzklebers mit dem Glasrand verbunden werden. Zugleich kann eine bajonettartige Verriegelung zusätzlich zu einem Formschluß zwischen Kunststoffrand und Kannenrand führen. Diese Verbindungen haben jedoch nur noch im wesentlichen eine Dichtungsfunktion, die mechanische Belastung ist sehr gering. Aus diesem Grund kann - je nach Ausführung des Kunststoffrandes - der Kannenrand auch mit größeren Toleranzen und damit billiger gefertigt werden, oder der Kunststoffrand mit einem anderen Kleber, z.B. einem mittelviskosen Silikonkleber, befestigt werden, als es im Stand der Technik erforderlich war. Es ist also jetzt möglich, den Kunststoffrand mittels eines elastischen, alterungsstabilen, dafür aber mechanisch weniger beanspruchbaren Klebers zu befestigen bzw. zu sichern.For example, the plastic edge is made according to the state of the art from polypropylene and connected to the glass edge using a polyamide hot melt adhesive. At the same time, a bayonet-type locking can also lead to a positive connection between the plastic edge and the edge of the jug. However, these connections only essentially have a sealing function, the mechanical load is very low. For this reason - depending on the design of the plastic edge - the can edge can also be manufactured with larger tolerances and thus cheaper, or the plastic edge with a different adhesive, e.g. a medium viscous silicone adhesive can be attached than was required in the prior art. It is therefore now possible to attach or secure the plastic edge by means of an elastic, aging-stable, but less mechanically stressable adhesive.

Erfindungsgemäß kann nun der Griff aus einem Kunststoff hergestellt werden, der z.B. für das Verkleben mit dem Material der Kanne, z.B. Glas, besser geeignet ist als der mit dem (heißen) Getränk in Kontakt kommende Kunststoffrand, der vorzugsweise aus Polypropylen gefertigt ist. Dies kann z.B. bei einem Griff aus ABS (Poly(acrylnitril-co-butadien-co-styrol)) oder PC (Polycarbonat) mittels eines dauerelastischen Silikonklebers erfolgen. Da diese hochfesten Silikonkleber meist hochviskos sind, sind sie für die Befestigung des Kunststoffrandes ungeeignet. Eine solche Verbindung erfüllt nun alle für den Gebrauch bezüglich Temperaturwechselfestigkeit Abrißfestigkeit und Spülmaschinentauglichkeit erforderlichen Bedingungen. Der Griff kann auch mittels eines um die Kanne herumgeführten Metallbandes oder auf andere bekannte Weise an der Außenseite des Kannenkörpers, statt wie bisher, am Ausgußrand und damit am Kannenhals, befestigt werden. Das Ankleben des Griffes ist jedoch die vorteilhafteste Befestigungsart, da sie kostengünstig ist und der Krug hierdurch keinerlei Metallteile aufweist, wodurch er mikrowellengeeignet ist.According to the invention, the handle can now be made of a plastic which is more suitable, for example, for gluing to the material of the jug, for example glass, than the plastic edge which comes into contact with the (hot) beverage and which is preferably made of polypropylene. This can be done with a handle made of ABS (poly (acrylonitrile-co-butadiene-co-styrene)) or PC (polycarbonate) using a permanently elastic silicone adhesive. Since these high-strength silicone adhesives are mostly highly viscous, they are unsuitable for attaching the plastic edge. Such a connection now fulfills all the conditions required for use with respect to temperature change resistance, tear resistance and dishwasher compatibility. The handle can also be guided around the jug Metal tape or in any other known manner on the outside of the can body, instead of as before, on the pouring rim and thus on the can neck. However, sticking the handle is the most advantageous type of attachment, since it is inexpensive and the jug does not have any metal parts, making it suitable for the microwave.

Es besteht zusätzlich die Möglichkeit, den Griff so zu gestalten, daß ein oberer Teil des Griffes in Eingriff mit dem Kunststoffrand steht. Hierdurch wird der Kunststoffrand durch Formschluß mit dem Griff auf dem Rand des Glaskrugs gesichert.There is also the possibility to design the handle so that an upper part of the handle is in engagement with the plastic edge. As a result, the plastic edge is secured by a positive fit with the handle on the edge of the glass jug.

Es besteht weiterhin die Möglichkeit, die Kanne mit einem zugehörigen Deckel in allen gebräuchlichen Formen auszustatten. Der Deckel kann lose aufgesetzt, in den Kunststoffrand eingerastet, als Schwenkdeckel in den Griff integriert sein, usw.It is also possible to equip the jug with an associated lid in all common forms. The lid can be placed loosely, snapped into the plastic edge, integrated as a swivel lid in the handle, etc.

Der als Ausguß dienende Kunststoffrand kann leicht in allen gewünschten Ausführungsformen - so z.B. mit angeformtem Ausguß - hergestellt werden. Man ist hierbei nicht auf Polypropylen beschränkt, auch andere lebensmittelechte Kunststoffe, die genügend steif und hitzebeständig sind, können verwendet werden. Der Kunststoffrand kann, insbesondere bei einer Sicherung durch den Griff, auch durch bloßes Einrasten am Kannenrand befestigt werden. Hierzu wird der Krugrand zweckmäßigerweise wulstförmig verdickt, so daß er in eine entsprechende Aussparung am Kunststoffrand einrasten kann. Durch diese bajonettartige Verriegelung werden beide Teile formschlüssig miteinander verbunden. Der Kunststoffrand wird hierbei zweckmäßigerweise so ausgestaltet, daß der obere Rand der Kanne in eine ringförmige Vertiefung am Kunststoffrand eingreift, wobei sich die innere Wand der ringförmigen Vertiefung an der Innenseite des oberen Glasrandes elastisch abstützt, so daß keine Flüssigkeit zwischen Kunststoffrand und oberen Kannenrand gelangen kann. Zweckmäßigerweise sitzt auch die äußere Wandung der ringförmigen Vertiefung auf der Außenseite der Kanne dicht auf, so daß kein Spülwasser in den Hohlraum gelangen kann.The plastic edge serving as a spout can easily be produced in all desired embodiments - for example with a molded spout. One is not limited to polypropylene, other food-safe plastics that are sufficiently rigid and heat-resistant can also be used. The plastic edge, especially when secured by the handle, can also be attached to the can edge simply by snapping it into place. For this purpose, the rim of the jug is expediently thickened in a bead-like manner so that it can snap into a corresponding recess on the plastic edge. This bayonet-like locking means that both parts are positively connected to one another. The plastic edge is expediently designed so that the upper edge of the can in one engages annular recess on the plastic edge, the inner wall of the annular recess being elastically supported on the inside of the upper edge of the glass, so that no liquid can get between the plastic edge and the upper edge of the can. Advantageously, the outer wall of the annular recess sits tightly on the outside of the jug so that no rinsing water can get into the cavity.

Bevorzugt wird der Kunststoffrand jedoch, wie beschrieben, vorzugsweise mit einem Schmelzkleber, vorzugsweise Polyamid, am oberen Kannenrand befestigt, wobei der beschriebene Formschluß der zusätzlichen Sicherung beider Teile dienen kann. Der Schmelzkleber füllt zweckmäßigerweise den Hohlraum zwischen Kunststoffrand und oberem Kannenrand zumindest weitgehend aus, so daß dort keine Flüssigkeit eindringen kann.However, as described, the plastic edge is preferably fastened to the upper can edge, preferably with a hot-melt adhesive, preferably polyamide, wherein the positive engagement described can serve to additionally secure both parts. The hot melt adhesive expediently at least largely fills the cavity between the plastic edge and the upper edge of the can, so that no liquid can penetrate there.

Eine sichere und flüssigkeitsdichte Verbindung zwischen Kunststoffrand und Kanne ist in allen Fällen leicht möglich, da die Verbindung - im Gegensatz zum Stand der Technik - vom Gewicht der Kanne entlastet ist.A secure and liquid-tight connection between the plastic edge and the jug is easily possible in all cases, since the connection - unlike the prior art - is relieved of the weight of the jug.

Vorzugsweise ist die Kanne aus Glas gefertigt, da Glas ein preiswerter und hygienischer Rohstoff ist. Für besondere Zwecke kann die Kanne wie auch der Griff aus Glaskeramik, Keramik, Steingut oder Porzellan sein, wobei dann diesen Materialien angepaßte Klebestoffe verwendet werden.The jug is preferably made of glass, since glass is an inexpensive and hygienic raw material. For special purposes, the jug and the handle can be made of glass ceramic, ceramic, earthenware or porcelain, in which case adhesives adapted to these materials are used.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawings and will be described in more detail below.

Es zeigen:

  • Fig. 1 einen Querschnitt durch eine erfindungsgemäße Kanne aus Glas mit Kunststoffrand und angeklebtem Griff;
  • Fig. 2 den oberen Rand einer Kanne mit bajonettartig befestigtem Kunststoffrand.
Show it:
  • 1 shows a cross section through a glass jug according to the invention with a plastic edge and a glued handle.
  • Fig. 2 shows the upper edge of a jug with a plastic edge attached in a bayonet-like manner.

Fig. 1 zeigt eine erfindungsgemäße Kanne 1 mit einem Glasbehälter 2, einem als Ausguß dienenden Kunststoffrand 3, einem Griff 4 und einem Deckel 5. Der Kunststoffrand 3 ist ringförmig und besteht aus einem verhältnismäßig steifen Kunststoff, wie z.B. Polypropylen. In den Kunststoffrand 3 ist eine ringförmige Vertiefung 6 so eingelassen, daß eine kurze innere Wand 7 und eine längere äußere Wand 8 gebildet wird. Das untere Ende 9 der inneren Wand 7 läuft dünn aus und ist flexibel. Einander gegenüberliegend weist der ringförmige Kunststoffrand 3 eine Ausgußtülle 10 und eine Kerbe 11 auf.1 shows a jug 1 according to the invention with a glass container 2, a plastic rim 3 serving as a spout, a handle 4 and a lid 5. The plastic rim 3 is ring-shaped and consists of a relatively rigid plastic, such as e.g. Polypropylene. In the plastic edge 3, an annular recess 6 is embedded so that a short inner wall 7 and a longer outer wall 8 is formed. The lower end 9 of the inner wall 7 runs thin and is flexible. Opposite each other, the annular plastic edge 3 has a pouring spout 10 and a notch 11.

Der Glasbehälter 2 hat einen zum Aufsetzen auf eine (nicht dargestellte) Heizplatte geeigneten Boden 12, eine bogenförmig nach oben zulaufende Seitenwand 13 und einen leicht nach außen geneigten Rand 14, wobei der ganze Glasbehälter 2 rotationssymmetrisch ist.The glass container 2 has a base 12 suitable for placement on a heating plate (not shown), an arcuate side wall 13 and a slightly outwardly inclined edge 14, the entire glass container 2 being rotationally symmetrical.

Beim Zusammenbau der Kanne wird die ringförmige Vertiefung 6 teilweise mit einem Schmelzkleber 15, vorzugsweise ein Polyamid-Schmelzkleber, gefüllt und auf den Rand 14 des Glasbehälters 2 gepreßt bis sich die äußere Wand 8 des Kunststoffrandes 3 auf der Außenseite 16 des Glasbehälters 2 abstützt. Dabei kommt die dünn auslaufende innere Wand 7 in Kontakt mit der Innenseite 17 des Randes 14, so daß ein verhältnismäßig glatter Übergang vom Glasbehälter 2 zum Kunststoffrand 3 entsteht. Die Menge des Schmelzklebers 15 ist vorteilhafterweise so bemessen, daß der beim Zusammenfügen entstehende Hohlraum zwischen der ringförmigen Vertiefung 6 und dem Rand 14 mit dem Schmelzkleber 15 zumindest weitgehend ausgefüllt ist.When assembling the jug, the annular recess 6 is partially filled with a hot melt adhesive 15, preferably a polyamide hot melt adhesive, and pressed onto the edge 14 of the glass container 2 until the outer wall 8 of the plastic rim 3 is supported on the outer side 16 of the glass container 2. The thinly tapering inner wall 7 comes into contact with the inside 17 of the edge 14, so that a Relatively smooth transition from the glass container 2 to the plastic edge 3 arises. The amount of hot-melt adhesive 15 is advantageously dimensioned such that the cavity that is formed during assembly between the annular recess 6 and the edge 14 is at least largely filled with the hot-melt adhesive 15.

Nach dem Aufsetzen des Kunststoffrandes 3 bildet die Kerbe 11 eine Ansatzhilfe für den Griff 4, so daß dieser ohne großen Aufwand dem Ausguß 10 genau gegenüberliegend und in der richtigen Höhe an der Außenseite 16 des Glasbehälters 2 befestigt werden kann. Der Griff 4 weist hierzu eine in die Kerbe 11 passende Nase 18 auf, und wird an seiner zum Glasbehälter 2 weisenden Kontaktfläche 19 mit einem dauerelastischen Silikonkleber 20 beschichtet. Nach dem Zusammenfügen von Griff 4 und Glasbehälter 2 bildet die Nase 18 eine formschlüssige Sicherung des Kunststoffrandes 3. Der Silikonkleber 20 bildet eine, auch für den Einsatz im Hotel- und Gaststättengewerbe geeignete, temperaturwechselfeste, abrißfeste und spülmaschinentaugliche Verbindung zwischen dem Glasbehälter 2 und dem Griff 4.After placing the plastic edge 3, the notch 11 forms an attachment aid for the handle 4, so that it can be attached to the spout 10 exactly opposite and at the correct height on the outside 16 of the glass container 2 without great effort. For this purpose, the handle 4 has a nose 18 which fits into the notch 11 and is coated on its contact surface 19 facing the glass container 2 with a permanently elastic silicone adhesive 20. After the handle 4 and the glass container 2 have been joined together, the nose 18 forms a form-fitting securing of the plastic edge 3. The silicone adhesive 20 forms a connection between the glass container 2 and the handle, which is also suitable for use in the hotel and restaurant industry and is resistant to temperature changes, tear-off and dishwasher-safe 4th

In den Kunststoffrand 3 kann der Deckel 5 mittels Nocken 21 fest eingesetzt werden, wobei eine Aussparung 22 das Ausgießen eines in den Glasbehälter 2 eingefüllten Getränkes gestattet.The lid 5 can be firmly inserted into the plastic rim 3 by means of cams 21, a recess 22 allowing a beverage poured into the glass container 2 to be poured out.

In Fig. 2 ist eine andere Befestigungsmöglichkeit zwischen dem Glasbehälter 102 und dem Kunststoffrand 103 dargestellt. Zum Unterschied zum Kunststoffrand 3 weist die äußere Wand 108 in der ringförmigen Vertiefung 106 eine umlaufende Einbuchtung 123 auf, in die das Ende des Randes 114 einrasten kann. Das Ende des Randes 114 weist hierzu vorzugsweise eine Verdickung 124 auf. Die Einbuchtung 123 ist so in der ringförmigen Vertiefung 106 angebracht, daß beim Einrasten der Verdickung 124 gleichzeitig das untere Ende der äußeren Wand 108 und das dünn auslaufende Ende der inneren Wand 107, wie in der Fig. 1 beschrieben, in Kontakt mit dem Glasbehälter 102 kommt. Der etwas elastische Kunststoff des Kunststoffrandes 103 dichtet dabei auf dem Glas des Glasbehälters 102 ab.Another fastening option between the glass container 102 and the plastic edge 103 is shown in FIG. 2. In contrast to the plastic edge 3, the outer wall 108 has a circumferential indentation 123 in the annular depression 106, into which the end of the edge 114 can snap. The For this purpose, the end of the edge 114 preferably has a thickening 124. The indentation 123 is mounted in the annular recess 106 such that when the thickening 124 engages, the lower end of the outer wall 108 and the thinly tapering end of the inner wall 107, as described in FIG. 1, come into contact with the glass container 102 is coming. The somewhat elastic plastic of the plastic edge 103 seals on the glass of the glass container 102.

Auch in die ringförmige Vertiefung 106 kann, wie in Fig. 1 beschrieben, ein Klebstoff eingefüllt werden. Dieser Klebstoff erhöht die Sicherheit der Verbindung Kunststoffrand 103/Glasbehälter 102 und verhindert gleichzeitig zuverlässig ein eventuelles Eindringen von Flüssigkeit in den zwischen der ringförmigen Vertiefung 106 und dem Rand 114 gebildeten Hohlraum.An adhesive can also be filled into the annular recess 106, as described in FIG. 1. This adhesive increases the security of the connection between the plastic edge 103 and the glass container 102 and at the same time reliably prevents any ingress of liquid into the cavity formed between the annular depression 106 and the edge 114.

Verschiedene Variationen der erfindungsgemäßen Kanne sind möglich. So kann der Glasbehälter 2, 102 z.B. eine im wesentlichen zylindrische Seitenwand 13 haben, der Kunststoffrand 3 kann ohne die innere Wand 7 oder äußere Wand 8 ausgeführt sein, der Kunststoffrand 3 sitzt dann direkt auf dem Ende des Randes 14 auf; die Wandung 25 des Kunststoffrandes 3 kann vielfältig ausgeführt sein, z.B. sehr steil und im Bereich des Ausgusses 10 verhältnismäßig lang; gemeinsam ist dabei immer, daß der Griff 4 an der Seitenwand 13 und nicht am Rand 14 am Glasbehälter 2 befestigt ist, damit die Befestigung des Kunststoffrandes 3 nicht mit dem gesamten Gewicht der Kanne 1 belastet wird.Different variations of the can according to the invention are possible. So the glass container 2, 102 e.g. have a substantially cylindrical side wall 13, the plastic edge 3 can be designed without the inner wall 7 or outer wall 8, the plastic edge 3 then sits directly on the end of the edge 14; the wall 25 of the plastic edge 3 can be designed in various ways, e.g. very steep and relatively long in the area of the spout 10; common is always that the handle 4 is attached to the side wall 13 and not on the edge 14 on the glass container 2, so that the attachment of the plastic edge 3 is not burdened with the entire weight of the can 1.

Auch andere Befestigungen des Griffes 4 sind möglich, so kann z.B. der Griff mittels eines um den Körper des Glasbehälters herumlaufenden Metallbandes befestigt werden. Auch ein Ankleben einer Grundplatte an dem Glasbehälter und ein Montieren des Griffes an dieser Grundplatte ist möglich.Other attachments of the handle 4 are also possible, for example the handle can be attached to the handle Body of the glass container metal tape running around are attached. It is also possible to glue a base plate to the glass container and mount the handle on this base plate.
