Description

Die Erfindung betrifft ein doppelwandiges Trinkglas, umfassend eine zumindest abschnittsweise durchsichtige Außenwand mit einer Außenwandaußenfläche und einer Außenwandinnenfläche und Innenwand mit einer Innenwandaußenfläche und einer Innenwandinnenfläche, wobei Innenwandaußenfläche und Außenwandinnenfläche einen Hohlraum definieren. Weiterhin betrifft die Erfindung ein Verfahren zur Herstellung eines bedruckten Trinkglases, wobei eine Außenwand mit einer Außenwandaußenfläche und einer Außenwandinnenfläche sowie eine Innenwand mit einer Innenwandaußenfläche und einer Innenwandinnenfläche zur Ausbildung eines Hohlraumes hergestellt werden.The invention relates to a double-walled drinking glass comprising an outer wall which is transparent at least in sections and has an outer wall outer surface and an outer wall inner surface and inner wall with an inner wall outer surface and an inner wall inner surface, wherein the inner wall outer surface and outer wall inner surface define a cavity. Furthermore, the invention relates to a method for producing a printed drinking glass, wherein an outer wall having an outer wall outer surface and an outer wall inner surface and an inner wall having an inner wall outer surface and an inner wall inner surface are formed to form a cavity.

Doppelwandige Trinkgläser sind im Stand der Technik bekannt. Die DE 20 2008 001 921 U1 beschreibt beispielsweise ein Trinkglas, das aus zwei separeten Gläsern besteht. Das innere Glas wird mit dem äußeren Glas an der Oberfläche verschmolzen, sodass ein isolierter Raum entsteht. Das Glas besitzt weiterhin einen rutschfesten Deckel aus Kunststoff mit einem Verschluss für einen Trinkhalm.Double-walled drinking glasses are known in the art. The DE 20 2008 001 921 U1 describes, for example, a drinking glass, which consists of two separate glasses. The inner glass is fused with the outer glass on the surface, creating an isolated space. The glass also has a non-slip plastic lid with a closure for a drinking straw.

Aus der DE 201 03 678 U1 ist ein Trinkglas mit einem Wärmespeicher für Kalt- und Warmgetränke bekannt. Dazu wird in einem Hohlraum des doppelwandigen Trinkglases ein Gel oder dergleichen zur Wärmespeicherung gefüllt. Bei Kaltgetränken wird das Trinkglas vor Gebrauch in einem Gefrierfach aufbewahrt, bei Warmgetränken wird das Trinkglas vor Gebrauch in einem Wasserbad erhitzt. Bei Trinkgläsern ist es weiterhin üblich, diese mit einem Aufdruck, beispielsweise zu Werbezwecken oder als Volumenangabe, zu versehen. Beispielsweise können die Aufdrucke mittels bekannter Drucktechniken unmittelbar auf eine Glasfläche des Trinkglases aufgedruckt sein, wobei beispielsweise eine Druckfarbe anschließend getrocknet und eingebrannt werden kann. Beispielsweise kommen Siebdruck, Tampondruck oder Foliendruckverfahren in Frage. Da derartige Gläser, beispielsweise in einer Spülmaschine oder beim Gebrauch, erheblichen Beanspruchungen ausgesetzt sind, ist der Aufwand, der für die Bedruckung der Trinkgläser eingesetzt wird, vergleichsweise hoch. Dies hat einen negativen Einfluss auf die Kosten, die bei der Bedruckung von Trinkgläsern anfallen.From the DE 201 03 678 U1 is a drinking glass with a heat storage for cold and hot drinks known. For this purpose, a gel or the like is filled for heat storage in a cavity of the double-walled drinking glass. at Cold drinks, the glass is stored in a freezer before use in hot drinks, the glass is heated before use in a water bath. In drinking glasses, it is still common to provide them with a print, for example for advertising purposes or as a volume indication. For example, the imprints can be imprinted by means of known printing techniques directly on a glass surface of the drinking glass, wherein, for example, a printing ink can then be dried and baked. For example, screen printing, pad printing or film printing process come into question. Since such glasses, for example, in a dishwasher or in use, are exposed to considerable stresses, the effort that is used for the printing of the drinking glasses, comparatively high. This has a negative impact on the costs associated with the printing of drinking glasses.

Es ist daher Aufgabe der Erfindung, ein Trinkglas mit einer Bedruckung vorzuschlagen, wobei der Aufwand für die Bedruckung möglichst gering sein soll.It is therefore an object of the invention to provide a drinking glass with a print, the cost of printing should be as low as possible.

Diese Aufgabe wird durch ein Trinkglas nach Anspruch 1 sowie ein Verfahren zur Bedruckung des Trinkglases nach Anspruch 7 gelöst.This object is achieved by a drinking glass according to claim 1 and a method for printing the drinking glass according to claim 7.

Insbesondere wird die Aufgabe durch ein doppelwandiges Trinkglas gelöst, wobei das Trinkglas eine zumindest abschnittsweise durchsichtige Außenwand mit einer Außenwandaußenfläche und einer Außenwandinnenfläche und einer Innenwand mit einer Innenwandaußenfläche und einer Innenwandinnenfläche umfasst, wobei Innenwandaußenfläche und Außenwandinnenfläche einen Hohlraum definieren. Weiterhin umfasst das doppelwandige Trinkglas mindestens einen Verbindungsabschnitt, durch den Außenwand und Innenwand verbunden sind. Innerhalb des Hohlraumes an der Innenwandaußenfläche und/oder Außenwandinnenfläche ist mindestens ein Aufdruck vorgesehen.In particular, the object is achieved by a double-walled drinking glass, wherein the drinking glass comprises an at least partially transparent outer wall having an outer wall outer surface and an outer wall inner surface and an inner wall having an inner wall outer surface and an inner wall inner surface, wherein the inner wall outer surface and outer wall inner surface define a cavity. Furthermore, the double-walled drinking glass comprises at least one connecting portion, are connected by the outer wall and inner wall. Within the cavity on the inner wall outer surface and / or outer wall inner surface at least one imprint is provided.

Ein Kerngedanke der Erfindung besteht darin, dass innerhalb des Hohlraumes eines doppelwandigen Trinkglases ein Aufdruck ausgebildet ist. Dadurch kann der Hohlraum durch synergistische Weise genutzt werden, um einerseits eine Isolierung bereitzustellen und andererseits einen Schutz für einen Aufdruck auszubilden. Die Kosten für die Herstellung eines bedruckten, doppelwandigen Trinkglases sind reduziert. Da der Aufdruck durch die Außenwand bzw. die Innenwand geschützt ist, ist ein vergleichsweise geringer Aufwand zur Aufbringung desselben notwendig. Weiterhin besteht ein ganz wesentlicher Vorteil darin, dass das Material (beispielsweise die Farbe) für den Aufdruck nicht unbedingt für den Menschen verträglich sein muss, da der Aufdruck durch die doppelwandige Ausbildung geschützt wird und so mit hoher Wahrscheinlichkeit ausgeschlossen werden kann, dass Material des Aufdruckes abgelöst wird und beim Trinken in den menschlichen Körper aufgenommen wird. Durch die Vergrößerung der Auswahl von in Frage kommenden Materialien kann der Kostenaufwand weiter reduziert werden; beispielsweise können Materialien zum Einsatz kommen, die nicht spültauglich bzw. spülmaschinentauglich sind. Vorzugsweise ist mindestens ein Aufdruck auf der Innenwandaußenfläche vorgesehen. Weiter vorzugsweise ist die Außenwand gegenüber der Innenwand derart angeordnet, dass die Aufdruckung auf der Innenwandaußenfläche durch die Außenwand vergrößert wird. Bei einer derartigen Ausführung wird auf synergistische Weise davon Gebrauch gemacht, dass Trinkgläser (üblicherweise) rund ausgebildet sind und somit eine ebenfalls rund bzw. rundlich ausgebildete Außenwand einen Aufdruck auf der beabstandeten Innenwand vergrößern kann. Dadurch kann Material eingespart werden. Weiterhin ist auch ein besonderer optischer Effekt erzielbar. Dazu kann die Außenwand beispielsweise entsprechende (von einer rundlichen Form abweichende) Geometrien aufweisen um den Aufdruck optisch zu verzerren, beispieslweise in einem ersten Abschnitt stärker zu vergrößern als in einem zweiten Abschnitt oder in einem ersten Abschnitt zu vergrößern, in einem zweiten Abschnitt jedoch zu verkleinern.A core idea of the invention is that an imprint is formed within the cavity of a double-walled drinking glass. As a result, the cavity can be used in a synergistic manner, on the one hand to provide insulation and, on the other hand, to provide protection for an imprint. The costs for producing a printed, double-walled drinking glass are reduced. Since the imprint is protected by the outer wall or the inner wall, a relatively low effort for application same necessary. Furthermore, a very significant advantage is that the material (for example, the color) for the imprint does not necessarily have to be compatible with humans, since the imprint is protected by the double-walled training and can be ruled out with high probability that material of the imprint is removed and is absorbed into the human body when drinking. By increasing the selection of candidate materials, the cost can be further reduced; For example, materials can be used that are not suitable for rinsing or dishwasher-safe. Preferably, at least one imprint is provided on the inner wall outer surface. Further preferably, the outer wall opposite the inner wall is arranged such that the imprint on the inner wall outer surface is increased by the outer wall. In such an embodiment, use is made in a synergistic way that drinking glasses are (usually) round in shape and thus a likewise round or roundish outer wall can increase an imprint on the spaced-apart inner wall. This can save material. Furthermore, a special optical effect can be achieved. For this purpose, the outer wall may, for example, have corresponding geometries (deviating from a rounded shape) in order to optically distort the imprint, for example in a first section to enlarge more than in a second section or in a first section to enlarge, but in a second section to reduce ,

In einer konkreten Ausführungsform ist das gesamte Trinkglas (abgesehen von mindestens einem Aufdruck) einstückig aus Glas gebildet. Das Trinkglas bildet also einen monolithischen (einstückigen) Glaskörper aus. Insbesondere kann das Trinkglas in einem Stück gegossen werden. Dadurch wird mit vergleichsweise einfachen Mitteln ein sicherer Schutz für den Aufdruck (beispielsweise Werbeaufdruck) gewährleistet. Die Herstellungskosten werden weiter gesenkt.In a specific embodiment, the entire drinking glass (apart from at least one imprint) is formed in one piece from glass. The drinking glass thus forms a monolithic (one-piece) glass body. In particular, the drinking glass can be poured in one piece. As a result, reliable protection for the imprint (for example advertising imprint) is ensured with comparatively simple means. The manufacturing costs are further reduced.

In einer bevorzugten Ausführungsform kann der Aufdruck derart beschaffen sein, dass sich mindestens eine Farbe und/oder Helligkeit des Aufdruckes in Abhängigkeit von der Temperatur ändert. Beispielsweise könnte vorgesehen sein, dass sich die Farbe des Aufdruckes beim Unter- oder Überschreiten einer Temperatur (beispielsweise eine vorbestimmte Trinktemperatur von 40 bis 70 °C, insbesondere 55 °C) ändert. Bei dieser Ausführungsform wird die Doppelwandigkeit also auch ausgenutzt, um spezielle farbempfindliche Aufdrucke auf Trinkgläser, die üblicherweise hohen Beanspruchungen ausgesetzt sind, dauerhaft aufzubringen. In einer konkreten Ausführungsform ist der Hohlraum fluiddicht versiegelt. Dadurch kann mit hoher Sicherheit ausgeschlossen werden, dass Material des Aufdruckes abgelöst wird und dem Benutzer des Trinkglases zugeführt wird. Dadurch können (praktisch) beliebige Materialien zum Einsatz kommen. Einschränkungen hinsichtlich gesundheitlicher Aspekte sind (praktisch) nicht vorhanden.In a preferred embodiment, the imprint may be such that at least one color and / or brightness of the imprint changes as a function of the temperature. For example, it could be provided that changes the color of the imprint when falling below or above a temperature (for example, a predetermined drink temperature of 40 to 70 ° C, in particular 55 ° C). In this embodiment, the double wallness so also used to permanently apply special color-sensitive imprints on drinking glasses, which are usually exposed to high stresses. In a specific embodiment, the cavity is sealed fluid-tight. This can be ruled out with high certainty that material of the imprint is replaced and the user of the drinking glass is supplied. As a result, (practically) any materials can be used. Restrictions on health aspects are (practically) absent.

Ein mittlerer Abstand oder auch ein Maximalabstand (insbesondere im Bereich der Aufdruckung) zwischen Innenwand und Außenwand kann zwischen 0,25 und 0,57 cm, insbesondere bei 0,5 cm liegen. Durch einen derartigen Abstand wird nicht nur eine gute Isolation erreicht, sondern auch zugleich eine optische Vergrößerung des Aufdruckes ermöglicht (wenn dieser auf der Innenwand aufgebracht ist). Dadurch wird mit einfachen Maßnahmen mehreren Funktionalitäten Rechnung getragen, was die Herstellungskosten reduziert.An average distance or even a maximum distance (in particular in the region of imprinting) between inner wall and outer wall can be between 0.25 and 0.57 cm, in particular at 0.5 cm. By such a distance not only a good insulation is achieved, but also at the same time allows an optical enlargement of the imprint (if this is applied to the inner wall). As a result, several functions are taken into account with simple measures, which reduces the production costs.

Die oben genannte Aufgabe wird unabhängig gelöst durch ein Verfahren zur Herstellung eines bedruckten Trinkglases, insbesondere der vorbeschriebenen Art, mit den Schritten:

  1. a) Herstellen einer Außenwand mit einer Außenwandaußenfläche und einer Außenwandinnenfläche sowie einer Innenwand mit einer Innenwandaußenfläche und einer Innenwandinnenfläche;
  2. b) Bedrucken der Außenwandinnenfläche und/oder der Innenwandaußenfläche mit mindestens einem Aufdruck; sowie
  3. c) Verbinden von Innenwand und Außenwand, derart, dass der Aufdruck innerhalb eines durch Innenwand und Außenwand definierten Hohlraumes liegt.
The above object is achieved independently by a method for producing a printed drinking glass, in particular of the type described above, with the steps:
  1. a) producing an outer wall having an outer wall outer surface and an outer wall inner surface and an inner wall having an inner wall outer surface and an inner wall inner surface;
  2. b) printing the outer wall inner surface and / or the inner wall outer surface with at least one imprint; such as
  3. c) connecting the inner wall and outer wall, such that the imprint lies within a cavity defined by inner wall and outer wall.

Hinsichtlich der Vorteile wird auf das oben beschriebene Trinkglas verwiesen. Vorzugsweise erfolgt in Schritt b) das Bedrucken vor dem Verbinden (Verschmelzen). Dadurch kann ein Aufdruck besonders einfach aufgebracht werden.With regard to the advantages, reference is made to the drinking glass described above. Preferably, printing takes place in step b) before joining (fusing). As a result, an imprint can be applied particularly easily.

Außen- und Innenwand sowie ggf. ein Verbindungsabschnitt können einstückig hergestellt werden, insbesondere miteinander verschmolzen werden. Außen- und Innenwand sowie ggf. ein Verbindungsabschnitt können vollständig aus Glas hergestellt werden, wobei ein zusammenhängender Glaskörper hergestellt werden kann. Der Hohlraum kann fluiddicht ausgebildet werden. Weiterhin kann der Hohlraum vollständig durch Außenwandinnenfläche und Innenwandaußenfläche gebildet werden. Ein separates Bodenelement oder dergleichen ist damit nicht (unbedingt) nötig.Outer and inner wall and possibly a connecting portion can be made in one piece, in particular fused together. The outer and inner walls and optionally a connecting portion can be made entirely of glass, wherein a coherent glass body can be produced. The cavity can be formed fluid-tight. Furthermore, the cavity can be formed entirely by outer wall inner surface and inner wall outer surface. A separate floor element or the like is thus not (necessarily) necessary.

Der Hohlraum kann mit Luft oder einem Edelgas gefüllt oder evakuiert werden. Dadurch wird die Isolierung des Hohlraumes (bei gleichzeitig vorhandenem Aufdruck) verbessert.The cavity can be filled or evacuated with air or a noble gas. As a result, the insulation of the cavity is improved (at the same time existing imprint).

Weitere Ausführungsformen ergeben sich aus den Unteransprüchen.Further embodiments emerge from the subclaims.

Nachfolgend wird die Erfindung auch hinsichtlich weiterer Merkmale und Vorteile anhand von Ausführungsformen beschrieben, die durch die Abbildungen näher erläutert werden.In the following, the invention will also be described in terms of further features and advantages with reference to embodiments, which are explained in more detail by the figures.

Hierbei zeigen:

  • Fig. 2 einen vertikalen Schnitt des Trinkglases gemäß Fig. 1.
Hereby show:
  • Fig. 1 an embodiment of a drinking glass according to the invention in a schematic oblique view; and
  • Fig. 2 a vertical section of the drinking glass according to Fig. 1 ,

In der nachfolgenden Beschreibung werden für gleiche und gleich wirkende Teile dieselben Bezugsziffern verwendet.In the following description, the same reference numerals are used for the same and like parts.

In der Schrägansicht gemäß Fig. 1 ist ein Trinkglas mit mehreren Aufdrucken 10 zu sehen. Gemäß Fig. 2 ist das Trinkglas doppelwandig ausgebildet und umfasst eine Außenwand 11 und eine Innenwand 12. Zumindest die Außenwand 11 (ggf. auch die Innenwand 12) ist durchsichtig (transparent) ausgebildet.In the oblique view according to Fig. 1 is a drinking glass with several imprints 10 to see. According to Fig. 2 the drinking glass is double-walled and comprises an outer wall 11 and an inner wall 12. At least the outer wall 11 (possibly also the inner wall 12) is transparent (transparent).

Auf einer Innenwandaußenfläche 13 sind die Aufdrucke 10 aufgebracht. Eine Innenwandinnenfläche 14 ist zur Aufnahme des Getränkes vorgesehen. Die Innenwand 12 umfasst einen (umlaufenden) Innenwandseitenabschnitt 15 sowie einen Innenwandbodenabschnitt 16.On an inner wall outer surface 13, the imprints 10 are applied. An inner wall inner surface 14 is provided for receiving the beverage. The inner wall 12 includes a (circumferential) inner wall side portion 15 and an inner wall bottom portion 16.

Die Außenwand 11 umfasst eine Außenwandaußenfläche 17, an der das Trinkglas festgehalten werden kann sowie eine Außenwandinnenfläche 18. Außenwandinnenfläche 18 und Innenwandaußenfläche 13 definieren einen Hohlraum 19, der beispielsweise mit Luft gefüllt sein kann.The outer wall 11 comprises an outer wall outer surface 17 against which the drinking glass can be held and an outer wall inner surface 18. The outer wall inner surface 18 and the inner wall outer surface 13 define a cavity 19, which can be filled with air, for example.

Analog zur Innenwand umfasst auch die Außenwand 11 einen Außenwandseitenabschnitt 20 sowie einen Außenwandbodenabschnitt 21.Analogous to the inner wall, the outer wall 11 also comprises an outer wall side section 20 and an outer wall floor section 21.

Durch den Innenwandbodenabschnitt 16 sowie den Außenwandbodenabschnitt 21 ist ein doppelter Boden 23 ausgebildet. Durch den Innenwandseitenabschnitt 15 und den Außenwandseitenabschnitt 20 ist auch ein Seitenbereich 24 des Trinkglases doppelwandig ausgebildet.Through the inner wall bottom portion 16 and the outer wall bottom portion 21, a double bottom 23 is formed. By the inner wall side portion 15 and the outer wall side portion 20 and a side portion 24 of the drinking glass is double-walled.

Die Innenwand 12 ist mit der Außenwand 11 in einem Verbindungsbereich 22 miteinander verschmolzen. Der Verbindungsbereich 22 definiert einen oberen, dem Boden 23 gegenüberliegenden, Rand. Ansonsten berühren sich Innenwand 12 und Außenwand 11 nicht. Dadurch wird bei einfacher Konstruktion eine gute Isolierung erreicht.The inner wall 12 is fused to the outer wall 11 in a connecting region 22 with each other. The connecting portion 22 defines an upper, the bottom 23 opposite edge. Otherwise, inner wall 12 and outer wall 11 do not touch. This achieves good insulation with a simple construction.
