Abstract
A cup made of a paper material having a fillable interior, which cup is formed by a conical sleeve and a bottom. The bottom is attached to the sleeve at the lower end of the interior with a bottom skirt in an essentially liquid-tight way. The sleeve and/or the bottom in the area of the bottom skirt and/or the bottom skirt itself comprises, at least in one area along the periphery, an outwardly projecting widening. A lower edge of the widening forms a standing surface for the cup. The widening can serve to hold another cup of the same type, and can act together with a similar cup during stacking. The cup can include a heat insulating outer sleeve.
Claims25
A process for producing a cup from a paper material comprising the steps of:
- providing a cup including a conical sleeve member and a bottom member attached to the conical sleeve member in a liquid-tight manner with a bottom skirt such that the cup has an essentially liquid-tight fillable interior, the bottom member of the cup being attached to the conical sleeve member in an area of the conical sleeve member having a reduced diameter, and the bottom member having a bottom wall which defines part of the fillable interior of the cup;
- thereafter widening:
- the conical sleeve member adjacent an area of the bottom skirt outwardly in at least one area located along a circumference of the conical sleeve member;
- or the bottom member adjacent an area of the bottom skirt outwardly in at least one area located along a circumference of the bottom member;
- or the bottom skirt outwardly in at least one area along a circumference of the bottom skirt, to form an outwardly projecting widening disposed below the bottom wall of the bottom member and having a lower terminal edge defining a supporting surface of the cup;
- forming a holding structure on the conical sleeve member at a location spaced upwardly from the bottom wall, whereby the cup has respective dimensions defined at the holding structure and the lower terminal edge which are sized to permit support of the lower terminal edge of a first previously produced cup on the holding structure of a second previously produced cup when the first and second cups are vertically stacked;
- said step of providing includes providing the cup with an imaginary line substantially parallel to the conical sleeve member and extending upwardly from the lower terminal edge of the widening and together with the conical sleeve member defining an outer space around the cup;
- and
- providing an outer sleeve within the outer space at a location above the widening.

- widening:
- the conical sleeve member adjacent an area of the bottom skirt outwardly in at least one area located along a circumference of the conical sleeve member;
- or the bottom member adjacent an area of the bottom skirt outwardly in at least one area located along a circumference of the bottom member;
- or the bottom skirt outwardly in at least one area along a circumference of the bottom skirt, to form an outwardly projecting widening disposed below the bottom surface of the bottom member and having a lower edge defining a supporting surface of the cup, the widening having a first dimension at a location along the cup where the widening first projects outwardly and a second dimension located between the location of the first dimension and the lower edge, the second dimension being greater than the first dimension;
- forming a holding structure on the conical sleeve member at a location spaced upwardly from the bottom surface, whereby the lower edge of a first previously produced cup is supported on the holding structure of a second previously produced cup when the first and second cups are vertically stacked;
- said step of providing includes providing the cup with an imaginary line substantially parallel to the conical sleeve member and extending upwardly from the lower edge of the widening and together with the conical sleeve member defining an outer space around the cup;
- and
- providing an outer sleeve within the outer space at a location entirely above the location of the first dimension of the widening so as not to be in contact with the widening at the location of the first dimension.

A process for producing a cup from a paper material comprising:
- attaching a conical sleeve member and a bottom member in a liquid-tight manner to one another with a bottom skirt to form a cup with a substantially liquid-tight fillable interior and so that a bottom surface of the bottom member defines part of the fillable interior of the cup;
- widening the conical sleeve member or the bottom member adjacent an area of the bottom skirt or widening the bottom skirt itself, to form a widening which is disposed below the bottom surface, projects radially outwardly in a direction away from a longitudinal centerline of the cup and has a lower edge defining a supporting surface of the cup, the lower edge defining a bottom outer diameter of the cup oriented transversely to the longitudinal centerline of the cup, wherein an imaginary line extends upwardly from the lower edge of the widening substantially parallel to the conical sleeve member and together therewith defines an outer space around the cup;
- forming a holding structure on the conical sleeve member at a location spaced upwardly from the bottom surface, the cup having an inner diameter, oriented transversely to the longitudinal centerline of the cup, at the location of the holding structure which is similar to or greater than the bottom outer diameter of the cup to allow support of the lower edge of a first previously produced cup on the holding structure of a second previously produced cup when the first and second cups are vertically stacked with the first cup inside the second cup;
- and
- providing an outer sleeve within the outer space above the widening.
