Definitions

  • the invention relates to a cup made of a paper material with a fillable interior, which is formed by means of an at least partially conical shell and a bottom, wherein the bottom is connected in the region of the lower end of the interior substantially liquid-tight with the shell, wherein the interior bounding Sheath has at least one indentation and wherein the cup has a jacket surrounding the outer sheath at least partially, wherein the outer sheath is at least partially spaced from the sheath.
  • the invention also relates to a method for producing a cup of paper material.
  • Cups of paper material with a jacket and an outer jacket are from the German patent application DE 10 2004 056 932 A1 known.
  • the mantle of the inner cup has a stacking shoulder there, at which the diameter of the inner cup is suddenly reduced.
  • the stacking shoulder serves to make the bottom roll of the outer shell of another similar cup stacked on top of it Stacking shoulder rests. In the cup described there satisfactory stacking properties are achieved.
  • any stacking shoulder or any other form or indentation on the inside or outside of the jacket of such a cup always leads to a weakening of the paper material in the region of this indentation.
  • a double-walled cup made of a paper material in which an inner cup has radially outwardly extending formations in its upper portion adjacent to a mouth roll and in its lower portion adjacent to the bottom of the cup which extend over the entire circumference. A space between these upper and lower formations extends inward in the radial direction and is bridged by a flat outer shell, which is placed around the cup.
  • the outer jacket is materially connected to the inner cup in the region of the upper and lower moldings.
  • a cup made of a paper material and a method for producing a paper cup to be improved.
  • a cup made of a paper material with a fillable interior space with the features of claim 1 and a method with the features of claim 9 is provided.
  • the interior is formed by means of an at least partially conical jacket and a bottom, wherein the bottom is substantially liquid-tightly connected to the jacket in the region of the lower end of the interior, wherein the jacket bounding the interior has at least one indentation and wherein the cup a the jacket at least partially surrounding outer sheath, in which the outer sheath is materially connected in a first region above the indentation and in a second region below the indentation with the jacket.
  • Such a connection of the outer shell above and below the indentation can not only compensate for the material weakening caused by the indentation, but also significantly stabilize the cup in the area between the two integral connections, thus also in the region of the indentation.
  • an adhesive bond for example with cold glue or hot glue
  • a sealing compound for example by heat sealing of sealing wax or existing PE coatings, optionally with the interposition of spacer elements, a welded joint or the like may be provided.
  • the outer jacket or the sleeve stiffens the jacket, since it is connected above and below the indentation with this. The outer sheath thereby assumes forces that would be applied exclusively or mainly to the sheath without the two connections.
  • the recesses which are provided, for example, for stacking cups, thereby become more stable and higher cup bars can be formed, so more cups are stacked.
  • the Entstapelbarkeit the cup poles is guaranteed even with longer transport routes.
  • the stiffened cup according to the invention gives the consumer a secure feeling, since the cup is stable, especially in the filled state.
  • the outer casing can not move or only insignificantly move in the direction of the casing of the inner cup when a consumer has such a filled cup in his hand.
  • the stabilization of the shell of the inner cup through the outer shell can for example also be used to now use thinner material thicknesses for the inner cup, since a part of the stability of the inner cup is indeed effected via the outer shell or the sleeve.
  • the invention by arranging a connection of the outer sheath with the sheath of the inner cup above and below an indentation, all kinds of indentations in a sheath of a paper cup can be stiffened. In addition to a stiffening effect can be connected by the two compounds simultaneously the outer shell with the inner cup.

  • an adhesive track applied to the sheath and / or the outer sheath.
  • cold glue or hot melt glue can be used.
  • the adhesive trace is comparatively thick and applied in the form of a so-called adhesive bead, in order to maintain a distance between the outer shell and the jacket even in the bonded state. Such a distance improves the insulating properties of the paper cup.
  • At least one of the connections has at least a plurality of regions arranged one behind the other in the circumferential direction of the jacket and of the outer jacket.
  • the outer sheath can be connected to the sheath over the circumference of the sheath and the outer sheath in a first region above and a second region below the indentation.
  • a stabilization of the inner cup in the area of the indentation can take place essentially over the entire circumference of the outer casing and of the jacket of the inner cup.
  • the connection with the outer shell significantly stiffens the indentation when it is placed only briefly above and below the indentation, for example within one centimeter above and below the indentation. But the arrangement of the compound outside this range also contributes effectively to the stabilization of the indentation.
  • At least one of the connections takes place over the entire circumference of the jacket and of the outer jacket.
  • the outer jacket is at least partially spaced from the shell, whereby good insulating properties are achieved.
  • the bonding takes place by means of a bead of adhesive, which connects and glued together the spaced-apart surfaces of the outer shell and the shell.

  • the spacers are suitably directed outwardly from the jacket.
  • the spacers can be designed as separate from the shell and outer shell components.
  • the indentation is designed as a means for holding a similar cup in the stacked state of several cups.
  • Straight moldings that serve to stack cups are also exposed to high stacking forces in the case of high cup bars or cup stacks. Especially with such recesses, the invention can be used with great success.
  • the bottom and the jacket in the region of the liquid-tight connection form a bottom frame, wherein the indentation is formed as a means for holding the bottom frame of a similar cup in the stacked state of several cups.

  • the invention can significantly improve the stacking properties of such cups.
  • the indentation seen from an opening of the cup in the direction of the bottom, forms an at least partially cross-sectional reduction of the interior.
  • the invention can combine the good stacking properties of such a cross-sectional reduction with the clear stabilization of the jacket of the inner cup in the region of the indentation.
  • the outer jacket is located with its lower edge on an outer side of the floor frame and the lower connection between the outer jacket and the jacket is arranged below the indentation and above the floor.

A gluing perpendicular to the circumferential direction can additionally stabilize the indentation by the applied material for the cohesive bonding itself, in particular adhesive.
  • FIG. 1 shows in a sectional view two cups 10, 12 according to the invention of paper material, which are stacked in one another.
  • Both cups are identical and each have one, a fillable interior forming inner cup of a jacket 14 and a bottom 16.
  • the jacket 14 and the bottom 16 are each liquid-tightly connected to each other in the lower region of the cup to form a bottom frame 18.
  • the bottom frame 18 is conical, extending in a direction from the upper, open end of the cup 10, 12 in the direction of the lower end of the bottom frames 18 respectively.
  • a first, conically widening region 20 follows directly onto the bottom, followed by a cylindrical region 22.
  • the cylindrical portion 22 is about four to five times as long as the conically widening portion 20.
  • the cylindrical portion 22 is followed by a shoulder-shaped indentation 24, starting from the coat 14 then to its upper end a uniform, conical, itself has widening shape.
  • 14 of the jacket 14 is rolled into each case to form a mouth roll 26.
  • the shoulder-shaped indentation 24 forms a reduction in cross-section of the interior of the cups 10, 12.
  • the shoulder-shaped indentation 24, which is also referred to as a stacking shoulder, is encircling the entire circumference of the jacket 14 educated.
  • a diameter at the bottom of the bottom frame is formed so that the bottom frame 18 of the upper cup 10 can be supported on the indentation 24 of the lower cup 12. In this way, many of the cups 10, 12 can be stacked in one another.
  • Each of the cups 10, 12 is provided with a conical outer shell 28, wherein the outer shells 28 each begin just below the mouth roll 26 of the cups 10, 12 and then extend to below the bottom 16. Below the bottom 16, the outer shells 28 abut with their lower edge on an outer side of the bottom frame 18.
  • an upper adhesive track 32 and a lower adhesive track 34 are applied, each of which coat the jacket 14 with the outer jacket 28.
  • the adhesive tracks 32, 34 are applied as adhesive beads and bridge a distance between the sheath 14 and the outer sheath 28. Between the outer sheath 28 and the sheath 14 is thereby seen over the entire height of the outer sheath 28, with the exception of the lower edge of the outer sheath 28th , a substantially constant distance. This distance serves as an air gap insulation and ensures that a consumer can keep the cups 10, 12 well even when filled without the outer jacket 28 is too hot or too cold.
  • the adhesive trace 32 is disposed above the shoulder-shaped indentation 24 and the second adhesive trace 34 below the shoulder-shaped indentation 24.

  • the bonding of the outer jacket 28 to the jacket 14 in a first region above the indentation 24 and a second region below the indentation 24 can thereby effectively stiffen the jacket 14 of the inner cup.
  • the first, upper region or the upper bond is formed by the adhesive trace 32 and the second, lower region or the second bond is formed by the adhesive trace 34.
  • the outer jacket runs toward the jacket 14, so that a distance between the jacket 14 and the outer jacket 28 is reduced continuously.
  • a lower edge of the outer jacket 28 is then approximately at half the height of the bottom frame 18 on the outside.
  • the outer jacket 28 can thereby be supported not only on the second adhesive trace 34 on the jacket 14 in the lower region, but also on its lower, abutting the bottom frame 18 edge.

  • the outer jacket 28 is made from a flat blank and formed into a conical sleeve. This conical sleeve is then, after the two adhesive tracks 32, 34 were applied to the jacket 14, pushed from below over the bottom frame 18 to the respective inner cup. Simultaneously with the pushing an inner surface of the outer shell comes into contact with the adhesive tracks 32, 34, so that thereby the outer shell 28 is bonded to the respective inner cup.
