Description

The invention relates to a cup made of a paper material or a paper-like processable material with a fillable interior, which is formed by means of an at least partially conical shell and a bottom. The bottom is connected in the region of the lower end of the interior substantially liquid-tight with the jacket. The cup has an outer casing surrounding the casing at least in sections, so that an insulation space is formed between the casing and the outer casing.

Such a cup is for example from the document DE 10 2011 078 479 A1 known. Such cups are used, for example, for hot drinks, especially in the catering industry, where a return and rinsing of the cup is not desirable as a rule. Rather, the cup should be disposed of after a single use.

The insulation space serves to keep warm a drink contained in the interior as long as possible. This is done in particular by preventing heat transfer between the beverage and the surrounding atmosphere.

It has been found that the introduction of an insulating material into the insulation space can be advantageous for certain applications. Thus, the insulation effect can be increased and it can be maintained a constant distance between the outer jacket and jacket. This may be advantageous in particular when gripping or squeezing the cup while drinking. If the outer jacket and the jacket touch each other, the insulation effect is reduced to an undesirable degree.

As insulating material, for example, insulating materials are suitable, provided that they can be positioned by whatever process between the outer shell and the jacket. However, it has been found that typical insulation materials have a certain porosity or brittleness. Thus, it may happen that the insulating material "crumbles", which does not necessarily deteriorate the insulating effect, but may cause that when nesting cups of parts of the insulating material fall into another cup. This insulation material can float after filling a drink and irritate the customer of the hot beverage. In this case the customer can assume a contaminated drink and refuse to consume it.

The problems just mentioned mean that in the case of goblets of the generic type the use of insulating materials, in particular in the case of cups which are to be stacked in one another, is frequently omitted.

The invention further relates to a method for producing a cup, in which the problem arises that the generic cup produced suffers from the same disadvantages, which have just been described.

From the European patent application EP 2 371 723 A1 For example, a cup made of a paper material is known which is formed by means of a conical jacket and a bottom. The bottom is connected in the region of the lower end of the interior substantially liquid-tight with the jacket. The cup is provided with a jacket which partially surrounds the outer jacket, so that an insulation space is formed between the jacket and the outer jacket. To connect the outer shell with the jacket, an adhesive trace is provided, which partially bridges the insulation space.

From the US patent publication US 2009/0321508 is a cup with a conical jacket and a bottom known in which a jacket at least partially surrounding outer jacket is provided so that between the jacket and the outer jacket, an insulation space is formed. The insulation space can be partially filled with an insulating material. For example, an expandable insulation material or an adhesive may be provided. The outer jacket is spaced over its entire length by the insulation space of the jacket of the cup.

With the invention, a cup of a paper material or a paper-like processable material is to be specified, in which an insulating material is provided and which is still unproblematic stackable and manageable. It is a further object of the invention to provide a method for producing such a cup.

The invention relates to a cup made of a paper material or a paper-like processable material with a fillable interior, which is formed by means of an at least partially conical shell and a bottom. The bottom is connected in the region of the lower end of the interior substantially liquid-tight with the jacket. The cup has an outer casing surrounding the casing at least in sections, so that an insulation space is formed between the casing and the outer casing.

• der Isolationsraum zumindest teilweise mit Isolationsmaterial gefüllt ist, und
• zumindest unterhalb des Isolationsmaterials eine umfangsmäßig vollständig umlaufende untere Abdichtung gegen Austreten des Isolationsmaterials zwischen dem Mantel und dem Außenmantel ausgebildet ist.

According to the invention, it is provided that

• the insulation space is at least partially filled with insulation material, and
• at least below the insulating material, a circumferentially completely circumferential lower seal is formed against leakage of the insulating material between the jacket and the outer jacket.

By means of the sealing provided according to the invention, leakage of the insulating material on an underside of the cup can be effectively prevented. This bottom is in typical stackings such cups usually deep in another cup, so that at this point in generic cups there is a particularly high risk that insulation material enters another cup. The cup according to the invention thus enables a trouble-free combination of the advantages which result from the provision of an insulating material in the insulation space, with the advantages which result from a stacking of the cups.

In particular, the paper material or the paper-like processable material is a material which withstands exposure to typical drinks over typical periods of time in which the beverage is stored in the cup. For this purpose, plastic elements may be incorporated in the paper material. Likewise, a plastic material can be used, which can be processed similar to paper, in which therefore made of sheet material, a conical sleeve and a cup-shaped bottom and then connected to a finished cup.

• die untere Abdichtung dadurch ausgebildet ist, dass der Außenmantel mit dem Mantel an einem unteren Absatz verklebt, angeleimt oder angesiegelt ist,
• wobei der untere Absatz am Außenmantel ausgebildet ist und sich zum Mantel hin erstreckt.

Preferably, the lower seal is formed below the entire insulating material, which is arranged between the jacket and the outer jacket. Thus, the sealing effect of the seal extends to the entire insulating material, which is present in the cup. Falling out of parts of an insulating material, which may be located below the seal can be effectively prevented in this way. According to one embodiment, it is provided that

• the lower seal is formed in that the outer jacket is adhesively bonded, glued or sealed to the jacket at a lower shoulder,
• wherein the lower shoulder is formed on the outer shell and extends toward the shell.

Thus, an additional stiffening effect of the paragraph can be achieved and the outer shell can be easily connected to the jacket at a suitable location.

According to an alternative embodiment, the lower seal is formed by the outer jacket being rolled up towards the jacket and glued, glued or sealed to the jacket. The curl serves in particular to keep a distance between the outer shell and the jacket.

According to one embodiment, the outer shell is spaced at its lower edge from the shell and the lower seal is spaced from the edge running above. In such an embodiment can be dispensed with a buckling or curling of the outer shell.

In particular, in this case, the lower seal is preferably carried out in the form of a circulating adhesive, Papierbrei- or sealing bead. It can a circumferential bead advantageously produce the claimed cohesive connection between the outer shell and the jacket. A sealing lip-as an alternative approach-is typically an element which protrudes from the jacket toward the outer jacket or also protrudes from the outer jacket towards the jacket. In particular, the sealing lip closes off the space between the outer jacket and the jacket such that no parts of the insulating material can fall out at the bottom. Typically, in this case, spaced apart from the sealing lip, a bond is provided, which ensures that the outer jacket is arranged sufficiently close to the jacket, that the outer jacket presses against the sealing lip with a certain tension, or that the sealing lip bears against the jacket with a certain tension suppressed. Thus, the sealing effect required here can also be achieved. According to a preferred embodiment it is provided that above the insulating material, a circumferentially completely circumferential upper seal is formed against leakage of the insulating material between the jacket and the outer jacket. This can prevent leakage of insulation material on an upper side of the cup. This is particularly relevant if the cup is stored vice versa, for example, during transport or storage for storage in a restaurant of the system catering, ie, that the interior is open in this state down. Thus, for example, the penetration of dust or unwanted objects into the interior can be prevented.

• die obere Abdichtung dadurch ausgebildet ist, dass der Außenmantel mit dem Mantel an einem oberen Absatz verklebt, angeleimt oder angesiegelt ist,
• wobei der obere Absatz am Außenmantel ausgebildet ist und sich zum Mantel hin erstreckt.

Preferably, the upper seal is formed above the entire insulation material, which is arranged between the jacket and the outer jacket. Thus, the sealing effect of the seal extends to the entire insulating material, which is present in the cup. Falling out of parts of an insulating material, which may be located above the seal, can be effectively prevented in this way. According to one embodiment, it is provided that

• the upper seal is formed in that the outer jacket is adhesively bonded, glued or sealed to the jacket at an upper shoulder,
• wherein the upper shoulder is formed on the outer jacket and extends toward the jacket.

Thus, an additional stiffening effect of the paragraph can be achieved and the outer shell can be easily connected to the jacket at a suitable location.

According to an alternative embodiment, the upper seal is formed by the outer jacket being rolled up towards the jacket and glued, glued or sealed to the jacket. The curl serves in particular to keep a distance between the outer shell and the jacket.

According to one embodiment, the outer shell is spaced at its upper edge from the shell and the upper seal is spaced from the edge running below. In such an embodiment can be dispensed with a buckling or curling of the outer shell.

In particular, in this case, the upper seal is preferably designed in the form of a circulating adhesive, Papierbrei- or seal bead or in the form of a sealing lip. In this case, a circumferential bead can advantageously produce a cohesive connection between the outer jacket and the jacket. With regard to the use of a sealing lip, reference is made to the comments above.

Preferably, a number of completely circumferential central seals is arranged between the jacket and the outer jacket, insulation material being arranged both below and above each central seal. This can also be provided along a vertical direction of the cup a seal which acts only for a portion of the contained insulation material. This may be advantageous, for example, if so much insulating material is arranged above such a central seal that a single lower or upper seal would no longer be sufficient to effectively prevent it from escaping. As a result of the central seal, it is thus also possible to increase the amount of insulating material which may be contained in the insulation space.

According to one embodiment, the insulating material is formed in one or more large-area layers. In an alternative or combinable with this embodiment, the insulating material is formed in one or more circumferential beads. Large-area layers typically extend over a considerable part of the cup in the vertical direction. On the other hand, circumferential caterpillars typically have a vertical extent, which is considerably smaller than the entire vertical extent of the cup.

According to one embodiment, a number of middle splices are arranged between the jacket and the outer jacket, the middle splices being above the lower seal and are disposed below an upper edge of the outer shell and / or under the upper seal. Such splices may be particularly suitable for adhering the outer jacket to the jacket when using sealing lips, wherein such bonding can take place, for example, vertically in the center. This is particularly advantageous insofar as the sealing lips themselves do not provide a cohesive connection and thus also no holding action. In addition, to achieve the sealing effect of sealing lips a certain bias must be achieved, as described above. Such a bias can be achieved with the above-mentioned splices.

In contrast to the above-mentioned central seals a splice does not necessarily have to be performed completely encircling, since it does not have the task to prevent the leakage of insulation material, but only has the task to keep the outer jacket on the jacket.

According to respective embodiments, one, several or all seals can be made by means of a hotmelt adhesive, which can also be referred to as hotmelt. Likewise, one, several or all seals can be carried out by means of pulp. Such embodiments have proved to be advantageous.

Advantageously, the insulation material is formed from a physiologically harmless material. In particular, corn starch can be used for this purpose. This can be achieved that even in the event that a seal fails and the insulation material undesirably gets into a drink, no health damage is to be feared.

For stacking cups can preferably be provided a correspondingly long frame, which can rest on an underlying cup, or even in the cup formed inside stacking shoulder. This facilitates the stacking of cups, as in this way a defined distance between stacked cups is maintained. Too much tilting the cup, which may lead to permanent deformation of the cup or difficulties in removing cups from a stack, can thus be effectively avoided. The stacking shoulder is preferably formed circumferentially, but may also be formed only in sections.

• Aufbringen eines Isolationsmaterials, welches eine gewisse Brüchigkeit aufweist, auf den Mantel,
• Anbringen eines Außenmantels auf den Mantel, und
• Ausbilden zumindest einer Abdichtung gegen Heraustreten des Isolationsmaterials zwischen dem Außenmantel und dem Mantel.

The invention further relates to a method for producing a cup according to the invention from paper material or a paper-like processable material, the method comprising the following steps:

• essentially liquid-tight joining of a conical jacket and a bottom,
• Applying an insulating material, which has a certain brittleness, on the jacket,
• Apply an outer jacket to the jacket, and
• Forming at least one seal against the emergence of the insulating material between the outer shell and the jacket.

By means of the method according to the invention it is possible to produce a cup which has the advantages already mentioned above. With regard to the cup, it is possible to make use of all variants and embodiments described above. Illustrated benefits apply accordingly.

It should be understood that the steps mentioned can be performed in the order listed, but also in a different order. For example, first the insulating material can be applied to the jacket and then the outer jacket can be attached to the jacket. Alternatively, for example, the outer sheath may first be mounted on the sheath, and then insulation material may be introduced into the insulation space forming thereby. Likewise, the seal can be carried out before or after the application of the insulating material. This applies to both the lower and a possible upper seal.

Other features and advantages will become apparent to those skilled in the art upon consideration of the embodiments described below with reference to the accompanying drawings. Individual features of the described and illustrated embodiments can be combined in any way, without exceeding the scope of the invention.

Below, various embodiments of a cup 10 are shown. In this case, an overview of the respective cup 10 is given in each case first in a figure, which carries no letter in its name. Respective upper and lower areas are marked in this figure and marked with "a" and "b" respectively. These areas are shown in greater detail in the respective figures marked "a" and "b" respectively. Some embodiments are additionally shown with a further figure, which is stacked cups. This figure is marked with the letter "c".

Common to all exemplary embodiments is that the respective cup 10 has a jacket 20 and an outer jacket 30. The jacket 20 partially limits a fillable interior, in which a drink, in particular a hot beverage, can be added. The jacket 30 is designed conical. In the region of its lower end, the interior formed by the jacket 20 is closed by means of a cup-shaped bottom 24, which is fixed to the jacket 20 by the jacket 20 being bent over at its lower end and a peripheral bottom wall of the floor 24 between two sections of the jacket Mantels 20 glued, sealed and / or pressed. This illustrated embodiment of the floor 24 is merely exemplary, and it does not depend on the specific design of the floor for the execution of the invention described herein. For example, the bottom 24 and the jacket 20 could also be made in one piece.

The outer jacket 30 is suitably fixed to the jacket 20. This can be done for example by suitable Kleberaupen, which are arranged between the jacket 20 and the outer jacket 30. These can be executed all-round or only in sections. The adhesive beads need not meet in all cases, a sealing effect, although some embodiments are described below, in which they also have a sealing effect. Alternatively, the outer jacket 30 can also be sealed to the jacket 20.

Between the jacket 20 and the outer jacket 30, an insulation space 40 is formed. This serves to curb heat transfer between a hot or cold beverage contained in the cup and the environment. The insulation space 40 is at least partially filled with insulation material, which, depending on the exemplary embodiment, may be a caterpillar-shaped insulation material 50 or a laminar insulation material 52. This will be discussed in more detail in the discussion of the embodiments. Outside the respective insulating material 50, 52, the insulation space 40 is filled with air in the present case.

In order to prevent leakage of the insulating material 50, 52 between the jacket 20 and the outer jacket 30, the cups 10 according to the respective embodiments each have a lower seal 60 and an upper seal 70. How these seals 60, 70 are each exactly executed, will be described below with reference to the individual embodiments.

At the top of the jacket 20 has a mouth roll 22, which ensures in a conventional manner that the recorded in the cup 10 drink can be pleasantly drunk. In particular, the mouth roll 22 stabilizes an edge of the shell 20 to which a person usually attaches to drink.

The Fig. 1, 1st a and 1b show a cup 10 according to a first embodiment of the invention.

The upper seal 70 is designed such that the jacket 20 is bent toward the outer jacket 30 and thereby forms an upper shoulder 28, which may also be referred to as a paragraph. Above the upper shoulder 28, the outer sheath 30 and the sheath 20 are glued together along an upper surface adhesive bond 76. Since in this case a cohesive connection was formed, no insulation material 50 can escape through the upper seal 70.

The lower seal 60 is embodied in this first exemplary embodiment in that the outer jacket 30 is rolled on its underside and forms a lower rolled region 32. At the lower rolled-up region 32, a lower line-shaped bond 62 is formed toward the jacket 20, which forms a material-locking connection between the outer jacket 30 and the jacket 20. By means of the lower rolled-up region 32, a distance of the outer jacket 30 from the jacket 20 is defined. In addition, the caterpillar-shaped insulation material 50 contained in the insulation space 40 is prevented from escaping through this lower rolled region 32 together with the lower linear adhesive bond 62.

The Fig. 2 . 2a and 2 B show a cup 10 according to a second embodiment of the invention. The lower seal 60 is identical to the first embodiment. A renewed description is therefore omitted.

The upper seal 70 is formed the same as the lower seal 60, i. the outer sheath 30 forms at its upper end an upper rolled-up region 38, an upper linear adhesive 72 being formed between this upper rolled-up region 38 and the sheath 20. Thus, in the same way as just described with respect to the lower seal 60, an upper seal 70 is achieved, which prevents the insulating material contained in the insulating space 40 from escaping.

The Fig. 3 . 3a and 3b show a cup 10 according to a third embodiment of the invention. The upper seal 70 is designed in such a way that the outer jacket 30 is spaced at its upper end from the jacket 20 and slightly below the upper edge of an upper Kleberaupe 74 between the jacket 20 and the outer jacket 30 is formed. This upper Kleberaupe 74 runs completely around the entire circumference of the cup 10, so that the here flat insulating material 52 can not move past it. This allows the desired sealing effect of the upper Kleberaupe 72nd

The lower seal 60 is the same as the upper seal 70 in this embodiment. The outer jacket 30 is spaced at a lower edge of the jacket 20 and slightly above this lower edge, a lower Kleberaupe 64 between the shell 20 and outer shell 30 is arranged, which produces a material connection between the jacket 20 and the outer jacket 30. The lower adhesive bead 64 also completely runs around the entire circumference of the cup 10. Thus, it prevents the sheet-like insulating material 52, which is arranged in the insulation space 40 according to this embodiment, from emerging on the underside of the cup 10. The lower adhesive bead 64 is disposed below the bottom 24 and the outer shell extends to below the bottom 24th

The Fig. 4 . 4a . 4b and 4c show a cup 10 according to a fourth embodiment of the invention. The upper seal 70 is identical to the third embodiment. These will therefore not be discussed again.

In principle, the lower seal 60 is likewise the same as the lower seal 60 according to the third exemplary embodiment, with the inner jacket 20 additionally having a stacking shoulder 26 formed above the lower seal 60. In the present case, this stacking shoulder 26 consists of a peripheral region in which the jacket 20 is bent over toward the outer jacket 30, thus providing a support surface for another cup. This can be avoided when stacking cups 10 that they jam together and the removal of the cup 10 is difficult.

The outer jacket 30 has, in the fourth embodiment, a distance of the outer jacket 30 from the jacket 20 at the lower edge, which is reduced in size compared to the third embodiment. This is because the frame on which the peripheral wall of the bottom is received and glued or sealed between two portions of the outer jacket 30 widens again to the lower end of the cup.

An exemplary stacking of an upper cup 10 into a lower cup 10a is in FIG Fig. 4c shown. It can be seen that the upper cup 10 rests with its lower end, which is formed by the frame, but for holding the bottom 24 by 180 ° bent portion of the jacket 20 on the stacking shoulder 26a of the lower cup 10a. With regard to the individual components of the cups 10, 10a, reference is made in full to the description already given, wherein it should merely be noted that all components of the lower cup 10a are provided with the letter "a". Furthermore is Fig. 4c It can also be seen that, according to this exemplary embodiment, a laminar insulating material 52 is present in the insulation space 40, which occupies a large part of the insulation space 40. The insulating material 52 is also present in the area of the stacking shoulder 2 and can contribute to a stabilization of the stacking shoulder.

The Fig. 5 . 5a . 5b and 5c show a cup 10 according to a fifth embodiment of the invention. The upper seal 70 is identical to the first embodiment. The lower seal 60 is identical to the fourth embodiment. The stacking shoulder 26 is identical to the fourth embodiment. Reference is therefore made to the descriptions already made above and a repetition is omitted.

In contrast to the fourth embodiment, the cup 10 according to the fifth embodiment, no flat insulating material 52, but a caterpillar-shaped insulating material 50 on. Thus, a much larger part of the insulation space 40 is filled with air. The caterpillar-shaped insulation material 50 in this case essentially serves to keep a defined distance between the jacket 20 and the outer jacket 30.

Fig. 5c again shows two cups 10, 10a stacked on top of one another, wherein the reference numeral 10 again denotes the upper cup and reference numeral 10a denotes the lower cup. With regard to the individual components of the cup 10, 10a reference is made to the description already made. The components of the lower cup 10a are again marked with the letter "a". As well as above in Fig. 4c with reference to the fourth embodiment is also shown in FIG Fig. 5c to see that the upper cup 10 is suitably supported on the stacking shoulder 26a of the lower cup 10a, so that it can not be fully inserted into the lower cup 10a. This jamming of the cups 10, 10a is avoided in an advantageous manner.

The Fig. 6 . 6a . 6b and 6c show a cup 10. The upper seal 70 is designed such that the outer jacket 30 is spaced at its upper edge from the jacket 20 and slightly below this edge a sealing lip 78 is arranged. It should be noted that between the jacket 30 and the sealing lip 78 no cohesive connection is formed. Rather, the outer jacket 30 bears against the sealing lip 78 with a certain prestress. This bias is achieved by an adhesive bond, not shown, between the jacket 20 and the outer jacket 30 of the cup 10, which is arranged for example in the vertical center of the cup 10. The bias voltage is sufficient for an insulating material, which according to this exemplary embodiment is in the form of a caterpillar-shaped insulating material 50, not to be able to emerge from the insulation space 40 between the sealing lip 78 and the outer jacket 30. The lower seal 60 is carried out in the same way, wherein the outer jacket 30 is spaced at its lower edge of the jacket 20 and slightly above a lower sealing lip 68 is formed on the jacket 20, which extends to the outer jacket 30. Also at this lower sealing lip 68 of the outer jacket 30 is applied with a certain bias, which is generated by the bonding already described. Also, leakage of insulating material 50 from the insulation space 40 is prevented.

Fig. 6c again shows two cups 10, 10a, which are stacked in one another. The upper cup 10 is stacked in the lower cup 10a. Also in this case it is provided that a defined distance is maintained between the cups 10, 10a, wherein in contrast to the cups 10 according to the fourth and fifth embodiments, no stacking shoulder 26 is provided. Rather, the jacket 20 and thus also the frame of the upper cup 10 is pulled down so far that it rests on the bottom 24a of the lower cup 10a and still a distance between the outer shell 30 of the upper cup 10 and the inner shell 20a of the lower cup Consequently, the cup 10 can not be pushed further into the lower cup 10a. As a result, a lower limit for the distance between the two cups 10, 10a is defined, which is selected so that the cups 10, 10a can not get caught in each other. It is thus ensured that the cups 10, 10a can be easily separated from each other at any time.

The Fig. 7 . 7a . 7b and 7c show a cup 10. The lower seal 60 and the upper seal 70 are identically formed again by means of respective sealing lips 68, 78. Therefore, reference is made to the above description and waived a repetition.

In contrast to the cup 10 according to the sixth embodiment, the cup 10 according to the seventh embodiment, in turn, a stacking shoulder 26, which has already been described with reference to the fourth and fifth embodiments. In Fig. 7c In particular, it is shown that the stacking shoulder 26a of the lower cup 10a, into which an upper cup 10 is set, serves to support the upper cup 10 in a form already described above. With regard to the individual components shown and the functionality of the stacking shoulder 26, reference is made to the respective descriptions above.

The Fig. 8 . 8a and 8b show a cup 10 according to an embodiment of the invention.

The upper seal 70 is designed such that the outer jacket 30 has a shoulder 34, which extends to the jacket 20 out. At an upper edge of the outer sheath 30, the outer sheath 30 is glued to the sheath 20 along an upper surface adhesive bond 76. Alternatively, the flat adhesive bond 76 can also be designed as a seal. This upper surface bond 76 is basically similar to that discussed above with reference to the first embodiment. In contrast to the first embodiment, however, in the cup 10 according to the Embodiment of the jacket 20 no shoulder on, but is running up to the mouth roll 22 up smoothly. In contrast, the outer shell 30 is bent by the shoulder 34 to the shell 20 out and thus defines the distance of the outer jacket 30 from the jacket 20, which is required for the formation of the insulation space 40.

The lower seal 60 is formed in the same way as the upper seal 70. The outer shell 30 forms a lower shoulder 36, which is bent toward the jacket 20. At a lower edge of the outer jacket 30, the outer jacket 30 is glued to the jacket 20 along a lower surface bond 66. Also, the distance of the outer jacket 30 is defined by the jacket 20.

The respective laminar bonds 66, 76 prevent the caterpillar-shaped insulation material 50 contained in the insulation space 40, which is provided according to the eighth exemplary embodiment, from exiting the insulation space 40.
