Definitions
- the invention relates to a double-walled insulating cup made of paper material, such as paper or cardboard, with an inner cup, wherein the inner cup has a generally frusto-conical wall and a cup-shaped bottom, wherein the wall and the bottom are connected to each other by means of a bottom frame, and with an outer sleeve, wherein the inner cup has an upper shoulder in an upper half of the inner cup and a lower shoulder in a lower half of the inner cup, wherein on the upper shoulder an outer diameter of the inner cup, seen from the bottom of the inner cup to the upper edge of the inner cup, increases.
- the invention also relates to a method for producing a double-walled insulating cup made of paper material.
- the insulating cup has an outer sleeve with also frusto-conical wall.
- the outer sleeve abuts above the upper shoulder on the outer wall of the inner cup and below the lower shoulder also on the wall of the inner cup.
- a curling rolled up towards the inner cup may be provided in order to increase a distance between inner cup and outer sleeve in this area.
- EP 1 785 265 is a double-walled insulating cup known.
- a double-walled insulating cup made of a paper material and a method for producing a double-walled Isolierbechers be improved.
- an increased distance between inner cup and outer sleeve can be achieved, resulting in an improved insulation effect.
- the appearance of the cup is improved because the outer shell now extends to the lower edge of the bottom frame and thus the bottom frame and the floor are no longer visible from the outside. At the same time a printable area of the outer shell is thereby increased.
- a stability of the cup in particular a stability of the bottom frame can be increased, since the bottom frame is stiffened by the fact that the outer casing rests against this at least in the region of the lower edge of the bottom frame.
- an improved state of the cup can be achieved because there is more moldable material in the footprint and the footprint of the cup is increased.
- the insulating cup according to the invention is still stackable in the granted manner on the bottom frame.
- the outer sheath rests against the outside of the bottom frame, the outer sheath can be used with for destacking, so that the bottom frame does not have to be expanded or not so strong.
- the double-walled insulating cup according to the invention is easier to produce compared to known insulating cups, since the outer jacket no longer has to slide with its narrow end over the outer edge of the bottom frame, but can directly rest against it. This facilitates the production of the Isolierbechers and in particular the pushing of the outer shell on the inner cup considerably.
- the outer casing is folded around the lower edge of the floor frame.
- the outer shell can be attached to the floor frame in a simple and very stable manner.
- a footprint of the Isolierbechers is thereby formed by means of the lower edge of the outer shell. Such a footprint is greater than the lower edge of the bottom frame alone, so that an improved stability is achieved.
- the outer jacket is connected to an inner side of the floor frame with this.
- the connection of the outer shell with the bottom frame can be made invisible from the outside.
- the outer jacket is sealed to the inside of the bottom frame or glued to it. On the outside then only the outer shell can be seen, which extends to the lower edge of the cup.
- the outer shell does not have to rest on an outer side of the bottom frame, so that a very shapely cup results from the fact that the truncated cone shape of the outer shell is not interrupted from its upper end below a mouth roll to the lower end.
- Such an outer jacket can also be printed in a simple manner.
- the outer jacket is connected to the inner cup in the region of the upper shoulder.
- the outer shell has a truncated cone shape and extends from an underside of a mouth roll on the inner cup to a lower edge of the bottom frame.
- a very shapely insulating cup which has the outer roll of the inner cup and below the mouth roll at the top of the outer shell.
- the outer shell has a continuous truncated cone shape, which extends to the lower edge of the cup.
- the outer shell is at least partially in an abutment area flat against the floor frame, wherein the contact area extending from the lower edge of the floor frame upwards.
- the outer shell can be very securely connected by the flat system with the bottom frame.
- the planar contact of the outer jacket can either be on an outer surface of the bottom frame or, after folding the outer jacket, on an inner side of the bottom frame.
- a combination of outer shell and bottom frame is carried out by heat sealing or adhesive, for example by means of hot melt adhesive.
- an outer diameter of the outer jacket in a retracted area above the contact area tapers more than a truncated cone shape of the outer jacket above the retracted area.
- an inner and outer diameter of the outer shell above the region in which the outer jacket rests against the outside of the bottom frame be more tapered, as dictated by the truncated cone shape of the outer shell.
- a comparatively large distance between outer shell and inner cup can be maintained until just above the contact area, which ensures a good insulation effect.
- the outer shell is in a region of surface on the inner cup, which extends from the upper shoulder of the inner cup to an underside of a mouth roll at the upper end of the inner cup.
- the outer sheath can be very securely attached to this in the upper region of the inner cup.
- the upper shoulder can mark a level mark for the cup, so that usually no fluid can be found above the upper shoulder anyway, so that in this area, the reduced insulation effect is not detrimental due to the lack of air gap between the outer shell and inner cup.
- the problem underlying the invention is also solved by a method according to claim 8 for producing a double-walled Isolierbechers of a paper material.
- the outer shell is already formed from a circular segment-shaped blank to a frusto-conical sleeve and is pushed in this frusto-conical state from the bottom of the inner cup, the production of the Isolierbechers can be facilitated. Above all, the attachment of the outer shell is facilitated because the narrow end of the inner cup does not have to slide over the bottom frame, but the narrow end of the outer shell is attached to the bottom frame of the inner cup itself. The narrow end of the outer shell and the bottom frame are easily accessible.
- the fastening of the narrow end of the outer shell to the floor frame by means of folding the narrow end to a lower edge of the floor frame.
- the outer shell is pushed onto the inner cup until a lower edge of the outer shell is at the level of a lower edge of the bottom frame and attaching the narrow end of the outer shell to the bottom frame by means Connecting an inner surface at the lower edge of the outer shell with an outer surface of the bottom frame.
- the outer sheath can be securely fastened to the floor frame without requiring the turning of the narrow end of the outer sheath around the floor frame.
- the presentation of the Fig. 1 shows in a sectional view a double-walled insulating cup 10 according to a first embodiment of the invention.
- the insulating cup 10 is provided with an inner cup 12 defining a fillable interior 14 and having a generally frusto-conical wall 16 and a bottom 18.
- the bottom 18 has a cup shape and is, facing away from the interior 14 with its open side, inserted into the lower, narrow end of the frusto-conical wall 12.
- the wall 16 and the bottom 18 are connected to each other by means of a peripheral floor frame 20.
- the formation of the circumferential floor frame 20 can be seen.
- the lower end of the frusto-conical wall 12 is wrapped around a lower end of the pot edge of the bottom 18 and both the in Fig. 2 right outside of the edge of the bottom 18 adjacent section of the wall 12 and the in Fig. 2 left inside section of the wall 12 are connected to the edge of the bottom 18 and thereby form the bottom frame 20.
- a connection can be made for example by heat sealing.
- To the paper material For example, cardboard or thick paper, of which the bottom 18 and the wall 12 are made to protect against the ingress of liquid, at least the inside of the wall 12 and the top of the bottom 18 are provided with a heat-sealable plastic layer. After turning over the lower edge of the wall 12 around the edge of the floor, as in Fig. 2 is shown, then the wall 12 can be sealed on one side or both sides of the edge of the cup-shaped bottom 18.
- the bottom frame 20 is exposed to a central longitudinal axis 22 of the Isolierbechers 10 slightly outward. From the inner space 14 delimiting portion of the bottom 18 to the lower edge of the bottom frame, therefore, the diameter of the inner cup 12 slightly widens.
- the inner cup 12 has a circumferential lower shoulder 24 in a lower half of the inner space 14 of the inner cup 12 and a peripheral upper shoulder 26 in an upper half of the inner space 14 of the inner cup 12.
- the inner cup 12 is further provided at its upper, wide end with a circumferential mouth roll 28.
- the circumferential top shoulder 26 may serve as a fill mark to indicate a correct level of liquid in the interior space 14.
- the inner diameter of the inner cup 12 initially widens in a region 30, followed by a cylindrical region 32 as far as the peripheral shoulder 24.
- the inner diameter of the inner cup 12 increases suddenly.
- the wall 16 of the inner cup 12 extends at a constant cone angle to the upper shoulder 26.
- the upper shoulder 26 extends the diameter of the wall 16 of the inner cup 12 again abruptly, then again assume a constant cone angle between the upper shoulder 26 and the underside of the mouth roll 28, which is slightly less than the cone angle between the lower shoulder 24 and the upper shoulder 26.
- circumferential shoulder 24 serves as a means for holding a stacked cup, as described below with reference to the Fig. 4 is explained.
- the upper shoulder 26 is provided to form an air gap with an insulating effect between an outer jacket 34 and the wall 16 of the inner cup 12.
- the outer shell 34 has a truncated cone shape, its cone angle is constant from its upper edge 40, which rests against an underside of the mouth roll 28, to the lower edge of the bottom frame 20 towards.
- the cone angle of the outer jacket 34 corresponds in the illustrated embodiment, the cone angle of the wall 16 of the inner shell 12 between the lower shoulder 24 and the upper shoulder 26, so that between the lower shoulder 24 and the upper shoulder 26, an air gap between inner cup 12 and outer shell 34 a has constant width.
- the outer casing 34 is folded over around the lower edge of the bottom frame 20, and a circumferential region 36 of the outer casing 34 lies flat on an inner side of the bottom frame 20.
- This region 36 is shorter than the bottom frame 20.
- the region 36 is flat against the bottom frame 20 and may be additionally connected thereto, for example by heat sealing, glue, hot melt adhesive or the like.
- the outer jacket 34 forms a base for the insulating cup 10 in the region of its lower edge 38.
- the outer jacket 34 bears against the wall 16 of the inner cup 12. In this area, if this is necessary for reasons of stability, the outer jacket 34 may be connected to the inner cup 12, for example by heat sealing, glue or hot melt adhesive. Due to the between the upper shoulder 26 and the mouth roll 28 slightly larger cone angle of the outer shell 34 compared to the cone angle of the inner cup 12 in this area, the outer shell 34 is again slightly below the mouth roll 28 slightly spaced from the inner cup 12. As in Fig. 1 can be seen, the outer sheath 34 has a constant cone angle from its upper end below the mouth roll 28 to the lower edge 38. Outer jacket 34 thereby provides a smooth, easily printable area over substantially the entire height of the cup.
- the presentation of the Fig. 4 shows sections of two stacked double-walled insulating cup 10 and 10A.
- the in Fig. 4 Upper insulating cup 10A is located at its lower edge, which is defined by the edge 38A of its folded outer shell 34A, on the circumferential lower shoulder 24 on the inner cup 12 of the lower insulating cup 10. Since the outer jacket 34A abuts the outside of the bottom frame 20A and is then unbeaten around the lower edge of the bottom frame 20A, the bottom frame 20A has to be expanded less extensively, as would be the case without the outer jacket 34A to still be able to safely stack on the lower shoulder 24 of the lower cup 10.
- An outer diameter of the outer shell 34A at its lower edge 38A is slightly smaller than an inner diameter of the inner cup 12 immediately above the lower shoulder 24 but larger than an inner diameter of the inner cup 12 immediately below the lower shoulder 24.
- the lower edge 38A of the upper cup 10A passes through at least in sections on the lower shoulder 24 of the lower cup 10, so that a safe stacking of numerous cups 10, 10A is possible.
- the outer shell 34A of the upper cup 10A is still slightly spaced from the inner wall 16 of the lower cup 10, so that when stacking and unstacking the cups 10, 10A, an air balance can take place and the cups 10, 10A are not stuck together.
- this lower edge 38A is stabilized not only by the bottom frame 20A but additionally by the outer jacket 34A. Compared to conventional cups, it is therefore possible to reduce the material thickness of outer sheath 34A, bottom 18A and wall 16A and still maintain sufficient stability in this lower region.
- FIG. 4 it can be seen, extend the wall 16 of the inner cup 12 of the lower insulating cup 10 and the outer jacket 34A of the upper Isolierbechers 10A above the lower shoulder 24 parallel to each other and at a small distance from each other.
- FIG. 5 shows the two nested insulating cups 10A and 10 in an upper area. It can be seen that the outer jacket 34A of the upper cup 10A and the wall 16 of the inner cup 12 of the lower cup 10 only to the upper shoulder 26 of the lower Isolierbechers 10 parallel to each other.
- the outer shells 34A and 34 are made of slightly thinner paper material than the respective inner cups 12A, 12.
- the representations of the Fig. 6 and Fig. 7 show a sectional views of a double-walled Isolierbechers 50 according to the invention according to another preferred embodiment of the invention.
- the insulating cup 50 differs only in a few features of the insulating cup 10 of Fig. 1 so that only the distinguishing features will be explained below.
- the insulating cup 50 has an inner cup 12 which is identical to the inner cup 12 of the insulating cup 10 Fig. 1 is trained.
- the outer jacket 52 is retracted above its lower edge 54 in a region 56, so that a larger cone angle is present in the region 56 than between the region 56 and the upper edge 40 of the outer jacket 52.
- the upper edge 40 it follows the area 56 a contact area 58, in which the outer shell 52 rests flat against the outside of the bottom frame 20 of the inner cup 12.

- the outer shell 52 may be connected to the bottom frame 20, for example by heat sealing, glue or hot melt adhesive.
- FIG. 8 shows sections of two stacked double-walled Isolierbecher 50 and 50A.
- 10A in Fig. 4 For example, a radially outboard portion of the lower edge 54A of the outer jacket 52A of the upper cup 50A is used to seat on the lower shoulder 24 of the lower cup 50 thereby transmitting the stacking forces.

Die Erfindung betrifft einen doppelwandigen Isolierbecher aus Papiermaterial, beispielsweise Papier oder Pappe, mit einem Innenbecher, wobei der Innenbecher eine allgemein kegelstumpfförmige Wandung und einen topfförmigen Boden aufweist, wobei die Wandung und der Boden mittels einer Bodenzarge miteinander verbunden sind, und mit einer äußeren Hülse, wobei der Innenbecher eine obere Schulter in einer oberen Hälfte des Innenbechers und eine untere Schulter in einer unteren Hälfte des Innenbechers aufweist, wobei sich an der oberen Schulter ein Außendurchmesser des Innenbechers, gesehen vom Boden des Innenbechers aus zum oberen Rand des Innenbechers, vergrößert.The invention relates to a double-walled insulating cup made of paper material, such as paper or cardboard, with an inner cup, wherein the inner cup has a generally frusto-conical wall and a cup-shaped bottom, wherein the wall and the bottom are connected to each other by means of a bottom frame, and with an outer sleeve, wherein the inner cup has an upper shoulder in an upper half of the inner cup and a lower shoulder in a lower half of the inner cup, wherein on the upper shoulder an outer diameter of the inner cup, seen from the bottom of the inner cup to the upper edge of the inner cup, increases.
Die Erfindung betrifft auch ein Verfahren zum Herstellen eines doppelwandigen Isolierbechers aus Papiermaterial.The invention also relates to a method for producing a double-walled insulating cup made of paper material.
Aus der deutschen Offenlegungsschrift
Aus
Mit der Erfindung sollen ein doppelwandiger Isolierbecher aus einem Papiermaterial und ein Verfahren zum Herstellen eines doppelwandigen Isolierbechers verbessert werden.With the invention, a double-walled insulating cup made of a paper material and a method for producing a double-walled Isolierbechers be improved.
Diese Aufgabe wird durch einen doppelwandigen Isolierbecher nach Anspruch 1, sowie ein Verfahren nach Anspruch 8 gelöst.This object is achieved by a double-walled insulating cup according to claim 1, and a method according to claim 8.
Durch die Erfindung kann bei einem doppelwandigen Isolierbecher ein vergrößerter Abstand zwischen Innenbecher und äußeren Hülse erreicht werden, wodurch sich eine verbesserte Isolationswirkung ergibt. Das Erscheinungsbild des Bechers wird dadurch verbessert, da sich der Außenmantel nun bis zum unteren Rand der Bodenzarge erstreckt und dadurch die Bodenzarge und der Boden von außen nicht mehr sichtbar sind. Gleichzeitig wird dadurch eine bedruckbare Fläche des Außenmantels vergrößert. Weiter kann eine Stabilität des Bechers, insbesondere eine Stabilität der Bodenzarge erhöht werden, da die Bodenzarge dadurch versteift wird, dass der Außenmantel wenigstens im Bereich des unteren Rands der Bodenzarge an dieser anliegt. Darüber hinaus kann auch ein verbesserter Stand des Bechers erreicht werden, da sich mehr formbares Material im Bereich der Aufstandsfläche befindet und die Aufstandsfläche des Bechers vergrößert wird. Neben diesen Vorteilen ist der erfindungsgemäße Isolierbecher aber immer noch in gewährter Weise über die Bodenzarge abstapelbar. Indem der Außenmantel außen an der Bodenzarge anliegt, kann der Außenmantel mit zum Abstapeln verwendet werden, so dass die Bodenzarge nicht oder nicht so stark aufgeweitet werden muss. Schließlich ist der erfindungsgemäße doppelwandige Isolierbecher gegenüber bekannten Isolierbechern leichter herstellbar, da der Außenmantel mit seinem schmalen Ende nicht mehr über den äußeren Rand der Bodenzarge rutschen muss, sondern unmittelbar an dieser anliegen kann. Dies erleichtert die Herstellung des Isolierbechers und insbesondere das Aufschieben des Außenmantels auf den Innenbecher erheblich.With the invention, in a double-walled insulating cup, an increased distance between inner cup and outer sleeve can be achieved, resulting in an improved insulation effect. The appearance of the cup is improved because the outer shell now extends to the lower edge of the bottom frame and thus the bottom frame and the floor are no longer visible from the outside. At the same time a printable area of the outer shell is thereby increased. Next, a stability of the cup, in particular a stability of the bottom frame can be increased, since the bottom frame is stiffened by the fact that the outer casing rests against this at least in the region of the lower edge of the bottom frame. In addition, an improved state of the cup can be achieved because there is more moldable material in the footprint and the footprint of the cup is increased. In addition to these advantages, the insulating cup according to the invention is still stackable in the granted manner on the bottom frame. By the outer sheath rests against the outside of the bottom frame, the outer sheath can be used with for destacking, so that the bottom frame does not have to be expanded or not so strong. Finally, the double-walled insulating cup according to the invention is easier to produce compared to known insulating cups, since the outer jacket no longer has to slide with its narrow end over the outer edge of the bottom frame, but can directly rest against it. This facilitates the production of the Isolierbechers and in particular the pushing of the outer shell on the inner cup considerably.
In Weiterbildung der Erfindung ist der Außenmantel um den unteren Rand der Bodenzarge umgeschlagen.In a further development of the invention, the outer casing is folded around the lower edge of the floor frame.
Auf diese Weise kann der Außenmantel in einfacher und dabei sehr stabiler Weise an der Bodenzarge befestigt werden. Eine Standfläche des Isolierbechers wird dadurch mittels des unteren Randes des Außenmantels gebildet. Eine solche Standfläche ist gegenüber dem unteren Rand der Bodenzarge alleine größer, so dass eine verbesserte Standfestigkeit erreicht wird.In this way, the outer shell can be attached to the floor frame in a simple and very stable manner. A footprint of the Isolierbechers is thereby formed by means of the lower edge of the outer shell. Such a footprint is greater than the lower edge of the bottom frame alone, so that an improved stability is achieved.
In Weiterbildung der Erfindung ist der Außenmantel auf einer Innenseite der Bodenzarge mit dieser verbunden. Auf diese Weise kann die Verbindung des Außenmantels mit der Bodenzarge von außen unsichtbar erfolgen. Beispielsweise wird der Außenmantel an die Innenseite der Bodenzarge angesiegelt oder mit dieser verklebt. Auf der Außenseite ist dann lediglich der Außenmantel zu erkennen, der sich bis zum unteren Rand des Bechers erstreckt. Der Außenmantel muss dabei nicht an einer Außenseite der Bodenzarge anliegen, so dass sich ein sehr formschöner Becher dadurch ergibt, dass die Kegelstumpfform des Außenmantels von seinem oberen Ende unterhalb einer Mundrolle bis zum unteren Ende nicht unterbrochen ist. Ein solcher Außenmantel ist auch in einfacher Weise bedruckbar.In a further development of the invention, the outer jacket is connected to an inner side of the floor frame with this. In this way, the connection of the outer shell with the bottom frame can be made invisible from the outside. For example, the outer jacket is sealed to the inside of the bottom frame or glued to it. On the outside then only the outer shell can be seen, which extends to the lower edge of the cup. The outer shell does not have to rest on an outer side of the bottom frame, so that a very shapely cup results from the fact that the truncated cone shape of the outer shell is not interrupted from its upper end below a mouth roll to the lower end. Such an outer jacket can also be printed in a simple manner.
In Weiterbildung der Erfindung ist der Außenmantel mit dem Innenbecher im Bereich der oberen Schulter verbunden.In a further development of the invention, the outer jacket is connected to the inner cup in the region of the upper shoulder.
Auf diese Weise ist eine einfache Befestigung des Außenmantels am Innenbecher möglich und zwischen der oberen Schulter und dem unteren Rand der Bodenzarge ist der Außenmantel dadurch vom Innenbecher beabstandet, so dass eine gute Isolationswirkung erzielt werden kann.In this way, a simple attachment of the outer jacket on the inner cup is possible and between the upper shoulder and the lower edge of the bottom frame of the outer shell is characterized by the inner cup spaced, so that a good insulation effect can be achieved.
In Weiterbildung der Erfindung weist der Außenmantel eine Kegelstumpfform auf und erstreckt sich von einer Unterseite einer Mundrolle am Innenbecher bis zu einem unteren Rand der Bodenzarge.In a further development of the invention, the outer shell has a truncated cone shape and extends from an underside of a mouth roll on the inner cup to a lower edge of the bottom frame.
Auf diese Weise wird ein sehr formschöner Isolierbecher bereitgestellt, der am oberen Rand die Mundrolle des Innenbechers und unterhalb der Mundrolle den Außenmantel aufweist. Der Außenmantel weist dabei eine durchgehende Kegelstumpfform auf, die sich bis zum unteren Rand des Bechers erstreckt.In this way, a very shapely insulating cup is provided which has the outer roll of the inner cup and below the mouth roll at the top of the outer shell. The outer shell has a continuous truncated cone shape, which extends to the lower edge of the cup.
Gemäß der Erfindung liegt der Außenmantel wenigstens abschnittsweise in einem Anlagebereich flächig an der Bodenzarge an, wobei sich der Anlagebereich ausgehend vom unteren Rand der Bodenzarge aus nach oben erstreckt.According to the invention, the outer shell is at least partially in an abutment area flat against the floor frame, wherein the contact area extending from the lower edge of the floor frame upwards.
Auf diese Weise kann der Außenmantel durch die flächige Anlage sehr sicher mit der Bodenzarge verbunden werden. Die flächige Anlage des Außenmantels kann dabei entweder an einer Außenfläche der Bodenzarge oder, nach dem Umschlagen des Außenmantels, auf einer Innenseite der Bodenzarge liegen. Eine Verbindung von Außenmantel und Bodenzarge erfolgt dabei durch Heißsiegeln oder Klebstoff, beispielsweise auch mittels Schmelzkleber.In this way, the outer shell can be very securely connected by the flat system with the bottom frame. The planar contact of the outer jacket can either be on an outer surface of the bottom frame or, after folding the outer jacket, on an inner side of the bottom frame. A combination of outer shell and bottom frame is carried out by heat sealing or adhesive, for example by means of hot melt adhesive.
In Weiterbildung der Erfindung verjüngt sich ein Außendurchmesser des Außenmantels in einem eingezogenen Bereich oberhalb des Anlagebereichs stärker als eine Kegelstumpfform des Außenmantels oberhalb des eingezogenen Bereichs.In a further development of the invention, an outer diameter of the outer jacket in a retracted area above the contact area tapers more than a truncated cone shape of the outer jacket above the retracted area.
Auf diese Weise kann ein Innen- und Außendurchmesser des Außenmantels oberhalb des Bereichs, in dem der Außenmantel außen an der Bodenzarge anliegt, stärker verjüngt werden, als dies die Kegelstumpfform des Außenmantels vorgibt. Auf diese Weise kann bis unmittelbar oberhalb des Anlagebereichs ein vergleichsweise großer Abstand zwischen Außenmantel und Innenbecher aufrecht erhalten werden, der für eine gute Isolationswirkung sorgt.In this way, an inner and outer diameter of the outer shell above the region in which the outer jacket rests against the outside of the bottom frame, be more tapered, as dictated by the truncated cone shape of the outer shell. In this way, a comparatively large distance between outer shell and inner cup can be maintained until just above the contact area, which ensures a good insulation effect.
In Weiterbildung der Erfindung liegt der Außenmantel in einem Bereich flächig an dem Innenbecher an, der sich von der oberen Schulter des Innenbechers bis zu einer Unterseite einer Mundrolle am oberen Ende des Innenbechers erstreckt.In a further development of the invention, the outer shell is in a region of surface on the inner cup, which extends from the upper shoulder of the inner cup to an underside of a mouth roll at the upper end of the inner cup.
Auf diese Weise kann der Außenmantel auch im oberen Bereich des Innenbechers sehr sicher an diesem befestigt werden. Die obere Schulter kann eine Füllstandsmarke für den Becher markieren, so dass in der Regel oberhalb der oberen Schulter ohnehin keine Flüssigkeit zu finden ist, so dass in diesem Bereich auch die verringerte Isolationswirkung durch den fehlenden Luftspalt zwischen Außenmantel und Innenbecher nicht nachteilig ist.In this way, the outer sheath can be very securely attached to this in the upper region of the inner cup. The upper shoulder can mark a level mark for the cup, so that usually no fluid can be found above the upper shoulder anyway, so that in this area, the reduced insulation effect is not detrimental due to the lack of air gap between the outer shell and inner cup.
Das der Erfindung zugrundeliegende Problem wird auch durch ein Verfahren nach Anspruch 8 zum Herstellen eines doppelwandigen Isolierbechers aus einem Papiermaterial gelöst.The problem underlying the invention is also solved by a method according to claim 8 for producing a double-walled Isolierbechers of a paper material.
Indem der Außenmantel bereits aus einem kreisringsegmentförmigem Zuschnitt zu einer kegelstumpfförmigen Hülse geformt wird und in diesem kegelstumpfförmigen Zustand vom Boden her auf den Innenbecher aufgeschoben wird, kann die Herstellung des Isolierbechers erleichtert werden. Vor allem die Anbringung des Außenmantels ist dabei erleichtert, da das schmale Ende des Innenbechers nicht über die Bodenzarge hinüberrutschen muss, sondern das schmale Ende des Außenmantels an der Bodenzarge des Innenbechers selbst befestigt wird. Das schmale Ende des Außenmantels und die Bodenzarge sind dabei gut zugänglich.By the outer shell is already formed from a circular segment-shaped blank to a frusto-conical sleeve and is pushed in this frusto-conical state from the bottom of the inner cup, the production of the Isolierbechers can be facilitated. Above all, the attachment of the outer shell is facilitated because the narrow end of the inner cup does not have to slide over the bottom frame, but the narrow end of the outer shell is attached to the bottom frame of the inner cup itself. The narrow end of the outer shell and the bottom frame are easily accessible.
In Weiterbildung der Erfindung erfolgt das Befestigen des schmalen Endes des Außenmantels an der Bodenzarge mittels Umschlagen des schmalen Endes um einen unteren Rand der Bodenzarge.In a further development of the invention, the fastening of the narrow end of the outer shell to the floor frame by means of folding the narrow end to a lower edge of the floor frame.
Auf diese Weise kann eine sehr stabile Verbindung von Außenmantel und Bodenzarge erreicht werden.In this way, a very stable connection of outer shell and bottom frame can be achieved.
Der Außenmantel wird auf den Innenbecher aufgeschoben, bis ein unterer Rand des Außenmantels auf Höhe eines unteren Randes der Bodenzarge ist und das Befestigen des schmalen Endes des Außenmantels an der Bodenzarge erfolgt mittels Verbinden einer Innenfläche am unteren Rand des Außenmantels mit einer Außenfläche der Bodenzarge.The outer shell is pushed onto the inner cup until a lower edge of the outer shell is at the level of a lower edge of the bottom frame and attaching the narrow end of the outer shell to the bottom frame by means Connecting an inner surface at the lower edge of the outer shell with an outer surface of the bottom frame.
Auf diese Weise kann der Außenmantel sicher an der Bodenzarge befestigt werden, ohne das Umschlagen des schmalen Endes des Außenmantels um die Bodenzarge herum zu erfordern.In this way, the outer sheath can be securely fastened to the floor frame without requiring the turning of the narrow end of the outer sheath around the floor frame.
