Definitions

  • 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.
  • the introduction of an insulating material into the insulation space can be advantageous for certain applications.
  • 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.
  • insulating material for example, insulating materials are suitable, provided that they can be positioned by whatever process between the outer shell and the jacket.
  • typical insulation materials have a certain porosity or brittleness.
  • 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 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.
  • a cup made of a paper material 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.
  • an adhesive trace is provided, which partially bridges the insulation space.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • plastic elements may be incorporated in the paper material.
  • 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.
  • 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.
  • the outer shell is spaced at its lower edge from the shell and the lower seal is spaced from the edge running above.
  • the outer shell can be dispensed with a buckling or curling of the outer shell.
  • the lower seal is preferably carried out in the form of a circulating adhesive, Textilbrei- 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.
  • 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.
  • the sealing effect required here can also be achieved.
  • 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.
  • 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.
  • the penetration of dust or unwanted objects into the interior can be prevented.
  • 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.
  • the outer shell is spaced at its upper edge from the shell and the upper seal is spaced from the edge running below.
  • the outer shell can be dispensed with a buckling or curling of the outer shell.
  • the upper seal is preferably designed in the form of a circulating adhesive, Textilbrei- or seal bead or in the form of a sealing lip.
  • a circumferential bead can advantageously produce a cohesive connection between the outer jacket and the jacket.
  • 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.
  • the insulating material is formed in one or more large-area layers.
  • 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.
  • circumferential caterpillars typically have a vertical extent, which is considerably smaller than the entire vertical extent of the cup.
  • 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.
  • a certain bias must be achieved, as described above. Such a bias can be achieved with the above-mentioned splices.
  • 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.
  • one, several or all seals can be made by means of a hotmelt adhesive, which can also be referred to as hotmelt.
  • a hotmelt adhesive which can also be referred to as hotmelt.
  • one, several or all seals can be carried out by means of pulp. Such embodiments have proved to be advantageous.
  • the insulation material is formed from a physiologically harmless material.
  • 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.
  • the steps mentioned can be performed in the order listed, but also in a different order.
  • first the insulating material can be applied to the jacket and then the outer jacket can be attached to the jacket.
  • the outer sheath may first be mounted on the sheath, and then insulation material may be introduced into the insulation space forming thereby.
  • 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.
  • 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.

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.

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.
