Abstract

Cup made of paper material having a fillable interior space formed by a shell and a base. The base via a skirt at the lower end of the interior space is fastened in a substantially liquid-tight manner to the shell, and a lower periphery of the skirt forms a footprint for the cup. The cup has an external shell composed of a planar blank of paper or paper-like material. Longitudinal edges of the blank are connected to one another in an overlap region so that the external shell forms a sleeve. The external shell has a frustoconical shape having a first cone angle and, except for the overlap region, from the predefined spacing to the lower end is configured in a single ply. The shell, from the predefined spacing to the lower end, at least in portions tapers more heavily than in the region above the predefined spacing.

Abstract

An apparatus for manufacturing a sleeve for a paper cup and/or a paper cup comprises a machine frame and at least two star wheels, which are rotatably connected with the machine frame and which can be rotated in synchronized cycles. A first star wheel comprises a number of conical mandrels, on each of which one sleeve made of a flat-lying blank can be formed. The star wheels are positioned in one plane and are arranged to a vertical wall of the machine frame with horizontal rotary axes. The star wheels can be connected to at least one drive, whereby the drive is arranged on the side of the machine frame wall facing away from the star wheels.

Abstract

A multipart cover made of paper material and including a one-piece base body having a cover plate and a circumferential cover collar extending from the cover plate. The cover collar, when placed onto a container to be closed, extends upwards away from the container, and a reinforcement ring connected to the cover collar by means of a peripheral skirt. The reinforcement ring in a region below the cover plate, on a side of the cover plate opposite to the cover collar, includes a peripheral skirt forming a circumferential step along the periphery on a radially interior side of the reinforcement ring, or includes a circumferential bead along the periphery.

Abstract

Folding mandrel, device and method for manufacturing glued sleeves. The invention relates to a folding mandrel for a device for manufacturing glued sleeves, in particular paper sleeves for the manufacture of paper cups, where the folding mandrel is provided for winding of a plane segment and is so dimensioned that in the wound-on state of the segment an overlap containing adhesive is obtained. In accordance with the invention, the folding mandrel is provided with at least one recess for receiving any adhesive escaping from the overlap.

Abstract

A device and a process for transporting a sleeve, in particular for a cup or a can, in which the sleeve is transported during the production process from a first working station to a second working station. The sleeve is transported by a blast of air, whereby the blast of air is generated in the opposite direction to the transport direction of the sleeve. A first working station comprises a mandrel for taking up the sleeve. An air jet is provided for creating the blast of air, the mouthpiece of the air jet being directed towards the mandrel in the opposite direction to the transport direction of the sleeve.
