Abstract: A double-walled cup and a process for production of the cup are described. The cup includes an inner cup and a tube-shaped outer sleeve, which is formed from a blank of paper material joined at its ends. The tube-shaped outer sleeve is slid axially onto a prefabricated inner sleeve and secured. The tube-shaped outer sleeve is formed from a flat blank by joining the ends of the blank before being slid on, whereby the ends of the blank are joined by an adhesive applied to a limited area of the outer sleeve. The ends of the blank are joined by a thermoplastic material in the form of an adhesive, which for example can be a hot-melt adhesive or a sealing varnish.

Abstract: A method for fabricating a funnel, a tool for carrying out the method, and a funnel of flat material, more particularly of plastic-coated paper. A receptacle for a pulverulent and/or liquid medium includes a funnel disposed in a pouring or discharging region. A blank of flat material is shaped to a funnel-shaped sleeve having an outlet opening, an inlet opening, and an opening angle, and the funnel-shaped sleeve is swaged in at least one subregion to effect enlargement of the opening angle.

Abstract: Method and apparatus for producing a twin-wall cup from paper or paper-like material including placing an inner cup with a sleeve and a base onto a mandrel, laying a flat segment onto an outer side of the inner cup, opposite to the mandrel, shaping the flat segment to form an outer jacket, which surrounds the inner cup, and fixing the outer jacket on the inner cup by means of a material engagement connection of outer jacket and inner cup, in particular by means of adhesive bonding, wherein at least one spacer is attached to an inner side of the flat segment and/or to an outer side of the sleeve of the inner cup before the flat segment is laid on the inner cup.

Abstract: The invention relates to a method for fabricating a funnel, a tool for carrying out said method, and a funnel of flat material, more particularly of plastic-coated paper. The invention further relates to a receptacle for a pulverulent and/or liquid medium, comprising a funnel disposed in a pouring or discharging region. According to the invention, a blank of flat material is shaped to a funnel-shaped sleeve (3) having an outlet opening (30), an inlet opening (31), and an opening angle (?) and the funnel-shaped sleeve (3) is swaged in at least one subregion to effect enlargement of the opening angle (?).
