Definitions

  • the invention relates to a cup made of a paper material with a fillable interior, which is formed by a conical jacket and a bottom, wherein the bottom is secured at the lower end of the interior with a frame substantially liquid-tight manner on the jacket.
  • the invention further relates to a method for producing a cup from a paper material, which consists of a conical jacket and a bottom secured in the region of the smaller circumference of the shell by a frame.
  • a mug of this kind is through the JP2001-192015A State of the art.
  • the frame of the well-known cup widens downwards. The widening serves to fasten an outer jacket which surrounds the jacket bounding the inner space to form a cavity. Since the expansion of the frame, the distance between the inner shell and Defined outer jacket, the expansion of the frame must be circumferential along the circumference.
  • the outer jacket is placed around the frame, turned inwards and fastened there. When attaching the outer shell to the frame, it may happen that the tightness of the frame is impaired. In addition, the attachment of the outer sheath by wrapping is very expensive.
  • the outer shell completely encloses the frame, so that it is no longer visible from the outside.
  • the outer jacket can be pressed from the inside only with a very small force, which can accommodate the frame itself. If the pressure force is too high, the frame may tear, on the other hand, the attachment of the outer jacket may be deficient if the pressing force is too low.
  • the frame is a very important element of the cup.
  • the frame is necessary for the connection between the jacket and the floor.
  • At the frame are at least two layers of material in the thickness direction to each other, namely the material of the bottom and the material of the inner space bounding shell.
  • the bottom is designed cup-shaped, the open side of the filling opening of the cup is remote.
  • the at least two material layers are thus preferably arranged along the wall of the cup-shaped bottom.
  • the jacket is wrapped around the material of the floor, and that the frame consists of three or more layers of material.
  • the material of the floor is in the range with the material of the coat the frame glued or sealed to be liquid-tight at least for a certain period of time.
  • paper material from which the bottom and the jacket are made can be understood as meaning different materials which have at least one layer of paper, cardboard or cardboard.
  • the material may comprise one or more layers of plastic and / or aluminum.
  • the paper material is waxed or painted in order to have a resistance to the liquid to be filled into the interior.
  • the paper material is at least on the side bounding the interior with a thin plastic layer, preferably made of polyethylene, coated.
  • the moldability and in particular the extensibility of such paper material is limited. Too much deformation, the paper material itself or even a proposed coating tear, so that the tightness is impaired.
  • the frame is an essential design feature that can not be waived.
  • the invention is based on the object to simplify the manufacturability of a cup of the type mentioned and to avoid sealing problems on the frame.
  • the object is achieved in that the jacket and / or the bottom in the region of the frame and / or the frame itself at least in an area along the circumference has an outwardly projecting widening, and that a lower edge forms a base for the cup.
  • the object is achieved in the method in that the bottom is connected to the jacket to form a frame, wherein during the formation of the frame of the jacket and / or the bottom in the frame and / or the frame itself at least in one area along the periphery is widened outwardly, so that a lower edge of the expansion forms a base for the cup.
  • the base of the cup is enlarged by the expansion, so that the cup has improved stability.
  • the expansion is not or not completely covered by an outer shell, so that the material of the shell or the floor immediately forms the base.
  • the frame can not be impaired in its tightness by the attachment of the additional material of the outer shell.
  • the expansion is continuous and uniform along the circumference. When the paper material is coated, it is advantageous to make the expansion only so great that the coating does not tear.
  • the frame is widened over its entire height.
  • the frame then has - seen in an axial section - a substantially constant angle of inclination to the central axis of the cup.
  • the frame contains different height ranges which have different angles of inclination.
  • the area of the frame adjoining the bottom can remain in its original form, while the lower edge of the frame is increasingly widened.
  • the upper height range may serve primarily to seal the fillable interior and connects the conical shell substantially liquid-tight to the floor. In this upper height range of the jacket and the wall are sealed or glued together.
  • the material of the inner space bounding shell and / or the wall of the floor is expanded and forms with its lower edge an enlarged footprint for the cup.
  • a liquid-tight connection between the material of the bottom and the material of the shell is no longer absolutely necessary, so that sealing or bonding in the lower height range can be at least partially eliminated.
  • the cup of the invention can be used very versatile, since it can be used both without outer sheath and with different outer shells.
  • a heat-insulating jacket is provided, which partially surrounds the jacket bounding the interior space to form a cavity.
  • the outer sheath is thereby preferably pushed onto the inner conical jacket limiting the inner space along the central axis and fixed after the frame has been formed and expanded.
  • a stackable cup is, for example, through the EP 1 227 042 B1 known.
  • the interior of the limiting jacket of the known cup has a first means for holding another cup of the same kind.
  • the known cup has on a outer shell, which surrounds the inner space bounding shell with a heat-insulating cavity, a second means for holding.
  • the second means for holding is formed by an inwardly directed curl mounted at the lower end of the outer shell.
  • the well-known cup has the disadvantage that the forces occurring during stacking are transmitted via the jacket bounding the interior and over the outer jacket.
  • the forces that must be passed within the cup from the first means for holding to the second means for holding, are first by the interior transferred limiting jacket to the junction between the inner shell and outer shell and passed through this connection point to the outer jacket.
  • the forces are then forwarded to the trained as Einrollung second means for holding and transferred there to the next cup.
  • both the inner shell and the outer jacket must be designed to be stable enough to absorb the forces occurring.
  • the joint between the outer shell and the inner shell must be designed for the maximum forces occurring.
  • the design freedom of the cup after the EP 1 227 042 B1 is disadvantageously limited because the attached to the outer jacket second means for holding must always be adapted to the dimensions of the first means for holding another cup of the same kind and to the forces to be transmitted. It is not possible to provide the outer shell with any shape, or to change its shape as desired. In addition, it is not possible to omit, if necessary, the outer shell, without losing the good stacking properties.
  • the cup according to the present invention it is provided that on the frame means for holding another cup of the same kind is arranged, which can cooperate in a stacking of the cup with a similar cup.
  • the means for holding is advantageously formed by the expansion. It is preferably provided that a first means for holding is arranged on the jacket bounding the inner space, which can cooperate with a second holding means attached to the widening of a similar cup when stacking the cup.
  • the second means for holding is arranged on the jacket bounding the interior or on the floor or on a frame, by which the jacket bounding the interior is connected to the floor.
  • the second means for holding is attached to a component of the cup that is in contact with the fillable interior.
  • the cup according to the invention has the advantage that it can be stacked safely and stably even without the presence of an outer jacket and can also be unstacked again without jamming. If it is provided to associate the cup with a heat-insulating outer jacket, it can be largely independent and free from the cup of the EP 1 227 042 B1 design existing restrictions. The forces occurring during stacking are forwarded only within the jacket delimiting the interior from the first means for holding to the second means for holding. An outer jacket is therefore not absolutely necessary. If, nevertheless, an outer sheath is to be present, then this is not claimed by the forces occurring during stacking.
  • the frame, by which the jacket bounding the interior space is connected to the floor, is a very stable part of the cup and is particularly well suited for absorbing forces.
  • the forces occurring during stacking are essentially transferred by the jacket bounding the inner space from the first means for holding onto the second means for holding, which can be formed by the widening on the frame. This makes it possible to form very stable stacks with a large number of cups, which do not then become wedged into one another when the stacks are exposed to shocks or, for example, jerkily set down on the ground.
  • the interior limiting coat and the ground are already strong enough to absorb the forces occurring during stacking, since they must also absorb the forces occurring during filling.
  • the dimensions of the second means for holding are adapted to the dimensions of the first means for holding another cup of the same type.
  • the first means for holding another cup of the same kind can be formed in any desired manner. It is essential that a contour is formed, the forces acting in the axial direction of the cup forces, so the forces acting when stacking between two cups record.
  • the first means for holding is preferably designed as a bead or rib, which is formed at least in a region along the circumference in the inner space bounding shell.
  • the bead or rib can be designed along the circumference continuously or with interruptions.
  • the cup has a heat-insulating outer shell
  • the design of the heat-insulating outer shell is arbitrary in itself.
  • the outer sheath can be made for example of a plastic-paper or composite material.
  • the outer sheath can also be corrugated, corrugated, embossed or provided with a foamed layer.
  • the outer sheath can also be designed as a multilayer, for example, a corrugated intermediate layer can be provided, which is covered by a smooth overlying outer layer.
  • the fixing of the outer shell to the inner cup can be done for example by sealing or gluing. It causes a secure connection between the outer shell and the inner space bounding shell, so that slipping of the outer shell is reliably prevented, even if the outer shell has only a small amount.
  • the outer casing ends below the first means for holding another cup of the same kind or even below the bottom.
  • the attached to the inner sheath first means for holding is thereby covered by the outer sheath and is no longer visible from the outside.
  • the outer shell ends above the expansion of the frame.
  • the expansion on the frame by an interaction of a arranged outside and inside the frame tool done.
  • the expansion can be formed very precisely.
  • the widening is advantageously widened so far outwards that a parallel to the inner wall bounding the casing extends at a certain distance outside of the jacket defining the inner space, at the lower edge of the widening.
  • the outer contour of the outer shell is within the parallels with the jacket bounding the inner space, which is applied to the expansion of the frame.
  • Cup 1 shown essentially consists of a conical shell 2 and a cup-shaped bottom 3.
  • the open side of the cup-shaped bottom 3 is arranged so that it faces away from the filling opening of the cup 1.
  • the bottom 3 is connected with its wall 31 in the region of the smaller circumference of the shell 2 liquid-tight with this by forming a frame 4.
  • the material of the jacket 2 is wrapped around the wall 31 of the bottom 3 and hammered inwards.
  • the jacket 2 and the bottom 3 form a fillable interior 5 of the cup 1.
  • the fillable interior 5 has a height A.
  • the inner space 5 delimiting shell 2 has at its upper edge, ie in the region of the larger circumference, an outwardly beaded mouth roll 6, which surrounds the filling opening.
  • the property "conical" of the shell 2 is understood to mean that the shell 2 in the in FIG. 1 shown longitudinal section of the mouth roll 6 to the bottom 3 at least partially tapers.
  • casing 2 has an angle of inclination ⁇ to the center axis 13 of the cup 1 in the region of the fillable interior 5 above a bead 8.
  • the jacket 2 then has up to the bottom 3 a circular cylindrical shape. It is irrelevant which shape of the jacket 2 has in cross section.
  • the jacket 2 is preferably circular in cross-section, but may alternatively also be, for example, oval or rectangular with rounded corners.
  • the cup 1 has a truncated cone-like shape in the case of a round cross-section of the conical shell 2, while in the case of a rectangular cross-section of the conical shell 2 it has a rather truncated pyramidal shape.
  • the frame 4 has at least in an area along its circumference an outwardly projecting widening 10.
  • widening is to be understood that the frame 4 is issued with respect to a circular cylinder about the central axis 13 to the outside, so that the frame 4 includes a down to the footprint expanding cross-sectional area.
  • a lower edge 14 of the expansion 10 on the frame 4 forms the base for the cup 1.
  • the cup 1 is in use on its footprint, which is increased by the expansion 10. As a result, tilting of the cup 1 is difficult.
  • the widening 10 is preferably designed circumferentially along the circumference of the frame 4.

It may be advantageous to deliver a correspondingly shaped counter-tool to the outer circumference of the frame 4 in order to support the formation of the widening 10. A particularly advantageous method for producing the cup 1 is described below with the aid of FIGS. 6 to 8 will be explained in more detail.

  • the outer jacket 17 has an inwardly directed curl 20, which likewise has a region 23 extending parallel to the outer jacket 17.
  • the curl 20 is supported below the bottom 3 on the frame 4.
  • the curl 20 is in contrast to FIG. 4 flattened and slightly compressed at the lower edge region 24 of the outer shell 17, so that there is a greater conicity of the outer shell 17 is present.
  • Deviating from the presentation of FIG. 5 can the cup 1 in the region of the shoulder 21 also be designed differently.
  • An advantageous variant in the region of the shoulder 21 is in FIG. 5A shown greatly enlarged.
  • the region 25 of the casing 2 extends between the mouth roll 6 and the shoulder 21 approximately parallel to the central axis 13.
  • the outer shell 17 can be pushed a little under the mouth roll 6 when pushed onto the inner cup 1, the upper edge portion 26 of the outer shell 17 is slightly compressed.
  • the edge region 26 thus does not continue the conical outer jacket 17 uniformly, but has a somewhat smaller diameter. If the outer jacket 17, as in FIG. 5A , shown with its upper edge a little inserted into the mouth roll 6, the result is a particularly good appearance of the cup 1, since the upper edge of the outer shell 17 is no longer visible. If the outer sheath 17 is inserted further into the mouth roll 6 in an unillustrated embodiment, the clamping of the outer sheath 17 by the material of the mouth roll 6 causes a fixation of the outer sheath 17. For certain applications, the clamping of the outer sheath 17 in the mouth roll 6 as only attachment of the outer jacket 17 may be sufficient.
  • the bead 8 of the first means 7 for holding the cups is adapted to the dimension Y of the second means 9 for holding another cup 1 'of the same kind. If the dimensions X and Y in the cups 1 of FIGS. 4 and 5 are identical to the different outer shells 17, all these cups 1 can be stacked in any combination with each other without jamming, since all outer shells 17 are within the space 16 between the parallel 15 and the interior 5 forming shell 2.
  • the outer side 22 of the outer shells 17 may have different structures.
  • the outer side 22 may, for example, be corrugated, embossed, corrugated or have a foamed coating. It can also be provided to carry out the outer jacket 17, for example, corrugated and additionally provide on the outer side 22 a smooth cover of the wave structure in the form of another jacket to further improve the insulating effect of the cup 1.
  • the design of the outer shell 17 with an upper curl 19 or the attachment of the outer shell 17 in the region of a shoulder 21 of the shell 2 have the advantage that even in a region just below the mouth roll 6, a very wide cavity 18 between shell 2 and outer shell 17th arises, which has a very high insulation effect.
  • the curl 19 or the shoulder 21 ensure even without additional means, such as foamed layers or corrugated layers within the cavity 18, that the distance between the jacket 2 and outer shell 17 is not reduced under pressure, for example by a cross-hand, and the Isolation effect is lost.
  • a conical outer shell 2 and an approximately cup-shaped bottom are formed.
  • the outer shell 2 has initially the shape of a conical sleeve and the bottom 3 has the shape of a truncated cone, which tapers parallel to the outer sleeve 2.
  • the bottom 3 and the outer shell 2 are not yet connected to each other, but only inserted into each other.
  • the outer casing 2 is attached to a mandrel 30, which has a frustoconical shape in a first region 29, in which, however, adjoins the tapered end of the frusto-conical portion 29, a further frusto-conical surface 32, which tapers more and the shaping the bead 8, see Fig. 1 , is provided.
  • the surface 32 is followed by a circular cylindrical region 33, at the free end of the bottom 3 abuts.
  • a diameter E of this circular cylindrical region 33 may be smaller, in particular about 0.5 mm smaller than the diameter D of the bottom, see also Fig.
  • the outer shell 2 can be compressed slightly more to form the bead 8, as would be possible with already sealed jacket 2 and bottom 3. Since the coat 2 as well as the bottom 3 off coated paper material, the bottom 3 can be at least slightly compressed. It is thereby possible to draw the bead 8 relatively far into the interior of the cup in order to ensure a safe stacking of several cups.
  • a mold 34 To form the bead 8 is next to the mandrel 30, a mold 34, the in Fig. 6 is shown, and in the direction of the arrow 35 upwards, to be driven towards the mandrel 30.
  • the molding tool 34 has a frustoconical surface 36, which corresponds in its conicity substantially to the surface 32 on the mandrel 30. The outer sleeve 2 is thus clamped between mandrel 30 and mold 34 and between the surfaces 32 and 36, the bead 8 is formed.
  • the molding tool 34 has a channel-shaped region 38, which in the sectional view of the molding tool 34 in FIG Fig. 6 is shown only in sections, but extends over 360 °.
  • the simultaneous turning over of the lower edge 37 of the shell 2 with the molding of the bead 8 facilitates the production of the cup according to the invention considerably.
  • the jacket 2 is wound from a circular segment over a mandrel and then glued or sealed along a longitudinal seam.
  • the longitudinal seam of the shell 2 in the region of the lower end 37 can not be glued or sealed.
  • This area is in the representation of Fig. 6 denoted by F. If the longitudinal seam in the area F is not glued or sealed, the sheath 2 can deform more freely when the lower end 37 is folded over, and corrugation of the paper material, which in principle is difficult to deform, is avoided.
  • the region F may extend from the lower edge 37 of the shell 2 even to the lower edge of the bottom 3, as in FIG Fig. 6 also indicated by the reference numeral F '.
  • the length F or F ' is thus variable and can be changed.
  • FIG. 7 shows a further embodiment of the invention, wherein, in contrast to the embodiment of Fig. 6 the shell 2 'has an initially conical shape, which then merges with the horizontal bottom 3' but into a cylindrical shape. Consequently, the bottom 3 'in this embodiment, a reverse pot shape with cylindrical circumferential wall 31.
  • an outer ring 38 is moved into the area below the bottom 3 '.
  • the shell 2 'facing inner surface of the outer ring 38 is exposed to the outside and has the angle that the frame 4 should take in the final state.
  • a plurality of inner jaws 39 are provided, wherein in the illustration of Fig. 8 only an inner jaw 39 is shown.
  • the inner jaws 39 can in the representation of Fig. 8 outwardly, are moved in the direction of the outer ring 38 and thereby press the folded edge 37 'against the wall 31 of the bottom 3' and against the inner surface of the outer ring 38th
  • a radially outwardly facing surface of the inner jaw 39 is arranged parallel to the inner surface of the outer ring 38 and also has the angle at which the frame 4 should be arranged in the final state,
  • the inner jaws 39 are for example part of a mandrel and can be moved by moving an in Fig. 6 not shown middle part are moved radially outward.
  • the outer ring 38 may be formed as a solid ring or, for example, as an openable ring to facilitate the sliding onto the shell 2 '.
  • a circumferential roller may be provided, which exerts a radially outward, in the direction of the outer ring 38 directed force on the edge 37 'and the wall 31 to the Frame 4 to form.
  • the cup remains on the mandrel 30th
  • the inner cup 1 is completed and can be removed from the mandrel 30.
  • the outer jacket 22 For the production of the outer jacket 22, this is first wound from a circular segment-shaped blank on a mandrel and connected to a frusto-conical sleeve. In the area of the lower, tapered end is then according to Fig. 9 initially a curl 40 vorgefomt. This curl 40 represents a precursor of the curl 20, as shown in the 4 and 5 is shown. For the production of in Fig. 5 The cup 40 is then flat pressed until the in Fig. 10 shown form of curl is reached. It will be appreciated that the lower edge of the outer shell 17, formed by the curl 20, is slightly retracted and therefore has a greater taper at the lower end, as previously discussed. In the presentation of the Fig.
  • a knurling or ribbing 41 indicated.
  • Such a knurling or corrugation 41 on the inside of the curl 20 can be provided to achieve a higher elasticity when pushing the outer sheath 17 on the inner cup 1.
  • an inner diameter V of the curl 20 is smaller than an outer diameter Y, see Fig. 5 of the frame 4.
  • the end of the outer jacket 17 with the curl 20 must therefore expand slightly in order to be pushed over the frame 4 can. This expansion is facilitated by the knurling or ribbing 41.
  • the longitudinal seam of the outer shell 17 may not be glued or sealed in the region of the curl 20. Thereby, a certain rising of the outer shell 17 in the region of the curl 20 is facilitated, so that the outer shell 17 can be pushed over the frame 4 and then contracts again, so that the curl 20 in the in Fig. 5 shown position on the outside of the frame 4 rests.
  • a diameter U at the upper end of the curl 20 is greater than the outer diameter Y of the frame 4.
  • Fig. 5 refer to.
  • the frame 4 runs on the slope, which is formed by the inside of the curl 20 and the further extension of the outer shell 17, this is widened, slips over the area with the largest diameter Y of the frame 4 away and then takes the in Fig. 5 shown position.
  • the outer sheath 17 is then held by the residual stress on the inner cup 1, since to remove the outer shell 17 this would have to be pulled over the conically widening frame 4 again.
