Abstract

The cup is of the throwaway type used in aeroplanes, and its double-wall structure ensures heat insulation by keeping the surface of contact with the finger at a distance from the inner cup (1). The outer cup (2) features a clamping ring (3) and a shoulder (4) while its bottom has a central projection with a hollow centre (6). The rim of the inner cup (1) is beaded over with edge (7) ensuring a grip on ring (3). For further thermal insulation the gap between the inner and outer walls can be evacuated or partially evacuated, which also helps hold the halves together.

Description

  

  
 



   Trinkgefässe dieser Art sind bekannt und werden insbe sondere als Wegwerfgefässe, beispielsweise zur Verabreichung von Getränken in Flugzeugen, verwendet. Bei diesen vorbe kannten Geräten ist zur Bildung eines Wärmeisolationsrau mes eine äussere Berührungsfläche in Abstand von der Ge fässinnenwand angeordnet, wobei diese Gefässe aus einem
Stück bestehen und in der Herstellung vergleichsweise teuer - sind. Abgesehen davon besassen sie keinen Lippenwulst, offenbar darum, weil durch eine entsprechende Formgebung der Herstellungspreis noch weiter erhöht würde.



   Der vorliegenden Erfindung lag die Aufgabe zugrunde, ein Trinkgefäss der eingangs genannten Art zu schaffen, wel ches mit einem Lippenwulst versehen ist, trotzdem wesent lich billiger hergestellt werden kann und dazuhin die Mög lichkeit bietet, zweifarbig ausgeführt zu werden.



   Das erfindungsgemässe Trinkgefäss ist dadurch gekenn zeichnet, dass es aus einem Innen- und einem Aussenbecher besteht, welche Becher längs ihrer Ränder sowie in ihrer
Mittelachse miteinander verbunden und abgesehen von den
Verbindungsstellen auf Abstand voneinander gehalten sind.



   In der Zeichnung ist eine beispielsweise Ausführungsform des Erfindungsgegenstandes im Schnitt dargestellt.



   Bei der betreffenden Ausführungsform besteht das Trink gefäss aus einem Innenbecher 1 und einem Aussenbecher 2.



   Der obere Rand des Aussenbechers 2 ist zur Bildung eines
Befestigungsringes 3 sowie einer Schulter 4 nach innen abge setzt. Des weitern ist sein Boden 5 leicht aufgewölbt und be sitzt in der Bechermittelachse einen nach innen vorspringen den Hohlzapfen 6. Der Rand des Innenbechers 1 ist zur Bil dung eines Verbindungsteiles 7 um   1800    nach aussen gebogen, welcher Verbindungsteil mit Presssitz auf den Befesti gungsring 3 des Aussenbechers 2 aufgebracht ist. Schliesslich weist der Innenbecher 1 in seiner Mittelachse einen nach aussen vorstehenden Vollzapfen 8 auf, der bei der Verbindung des Innen- mit dem Aussenbecher ebenfalls mit Pressitz in den Hohlzapfen 6 des Aussenbechers 2 eingetrieben wird.



   In einer anderen Ausführungsform ist der Befestigungsring 3 des Aussenbechers 2 unterschnitten und arbeitet mit einem entsprechend geformten Verbindungsteil des Innenbechers 1 zusammen, so dass die beiden Becher an ihren Rändern durch einen Schnappverschluss miteinander verbunden sind. Eine ähnliche Ausbildung ist auch in bezug auf die Verbindung der beiden Becher in der Mittelachse möglich.



   Dadurch entsteht ein doppelwandiges Trinkgefäss, wobei die beiden Einzelteile, nämlich der Innenbecher 1 und der Aussenbecher 2, abgesehen von den Verbindungsstellen auf Abstand voneinander gehalten sind. Das sich zwichen den Wänden der beiden Becher befindende Luftkissen dient dabei als Wärmeisolation, so dass auch heisse Getränke ohne weiteres in das betreffende Gefäss eingefüllt werden können.



  Dazu kommt, dass durch die Umbiegung des Randes des Innenbechers ohne weiteres Dazutun ein Lippenwulst entsteht, der das Trinken wesentlich angenehmer gestaltet. Endlich können infolge der Zweiteiligkeit des Trinkgefässes der Innen- und der Aussenbecher aus Kunststoff verschiedener Farbe hergestellt werden, was zur Verbesserung des Aussehens des   Tnnkgefässes    entscheidend beiträgt.



   Dazu kommt, dass die Formgebung der beiden miteinander verbundenen Becher eine äusserst einfache ist, wodurch die Herstellungskosten entscheidend gesenkt werden können.

 

   Zur Erleichterung der Einführung des Innenbechers in den Aussenbecher, insbesondere dann, wenn diese maschinell vorgenommen wird, besteht die Möglichkeit, entweder auf der Aussenseite des Innenbechers oder aber auf der Innenseite des Aussenbechers eine Anzahl - beispielsweise drei  Führungsrippen vorzusehen, um auf diese Weise den Eintritt des Vollzapfens 8 in den Hohlzapfen 6 bzw. des Befestigungsringes 3 in den Verbindungsteil 7 auch dann zu gewährleisten, wenn der Verbindungsvorgang automatisch und in sehr rascher Sequenz erfolgt.

   Drinking vessels of this type are known and are used in particular as special disposable vessels, for example for the administration of beverages in aircraft. In these vorbe known devices an outer contact surface is arranged at a distance from the Ge inner wall to form a Wärmeisolationsrau mes, these vessels from one
Pieces exist and are comparatively expensive to manufacture - are. Apart from that, they did not have a bulge lip, apparently because a corresponding shape would increase the manufacturing price even further.



   The present invention was based on the object of creating a drinking vessel of the type mentioned, wel Ches is provided with a lip bead, nevertheless can be manufactured wesent Lich cheaper and also offers the possibility of being made two-colored.



   The drinking vessel according to the invention is characterized in that it consists of an inner and an outer cup, which cups along their edges as well as in their
Central axis connected and apart from the
Connection points are kept at a distance from each other.



   In the drawing, an example embodiment of the subject invention is shown in section.



   In the embodiment in question, the drinking vessel consists of an inner cup 1 and an outer cup 2.



   The upper edge of the outer cup 2 is to form a
Fastening ring 3 and a shoulder 4 abge sets inward. Furthermore, its bottom 5 is slightly arched and be seated in the cup center axis a protruding inwardly the hollow pin 6. The edge of the inner cup 1 is bent to form a connecting part 7 by 1800 outwards, which connecting part with a press fit on the fastening ring 3 of the Outer cup 2 is applied. Finally, the inner cup 1 has in its center axis an outwardly protruding solid pin 8 which is also driven into the hollow pin 6 of the outer cup 2 with a press fit when the inner and outer cups are connected.



   In another embodiment, the fastening ring 3 of the outer cup 2 is undercut and works together with a correspondingly shaped connecting part of the inner cup 1, so that the two cups are connected to one another at their edges by a snap lock. A similar design is also possible with regard to the connection of the two cups in the central axis.



   This creates a double-walled drinking vessel, the two individual parts, namely the inner cup 1 and the outer cup 2, apart from the connection points, being kept at a distance from one another. The air cushion between the walls of the two cups serves as thermal insulation so that even hot drinks can easily be poured into the container in question.



  In addition, by bending the edge of the inner cup, a lip bulge is created without further effort, which makes drinking much more pleasant. Finally, due to the two-part nature of the drinking vessel, the inner and outer cups can be made of plastic of different colors, which makes a decisive contribution to improving the appearance of the drinking vessel.



   In addition, the shape of the two interconnected cups is extremely simple, which means that the production costs can be significantly reduced.

 

   To facilitate the introduction of the inner cup into the outer cup, especially if this is done mechanically, there is the possibility of providing a number - for example three guide ribs - either on the outside of the inner cup or on the inside of the outer cup, in order to allow entry of the solid pin 8 in the hollow pin 6 or the fastening ring 3 in the connecting part 7, even if the connecting process takes place automatically and in a very rapid sequence.
