An apparatus for producing containers from paper or paper-like material. The container has a lateral surface made of a wound sheet-like segment, of which segment edges arranged on longitudinal sides overlap and form a region of overlap, and a pan-like termination element. The lateral surface and the termination element are connected to one another in an essentially liquid-tight manner by skirt, and at least one pressing ram is provided for pressing and sealing the skirt, the pressing ram subjecting the skirt to essentially radially directed pressure. The pressing ram has a radially projecting protrusion in a portion provided for the purpose of acting on a boundary portion of the region of overlap of the lateral surface of the skirt.
Apparatus for producing containers from paper material or paper-like material, wherein the container has a lateral surface made of a wound sheet-like segment, of which the segment edges arranged on the longitudinal sides overlap and thus form a region of overlap, and also has a pan-like termination element, that is to say a pan-like base and/or a pan-like lid, wherein the lateral surface and the termination element are connected to one another in an essentially liquid-tight manner by means of a skirt, wherein at least one pressing ram is provided for the purpose of pressing and sealing the skirt, the pressing ram subjecting the skirt to essentially radially directed pressure, wherein the pressing ram has a radially projecting protrusion in a portion of the pressing ram provided for the purpose of acting on a boundary portion of the region of overlap of the lateral surface on the skirt.
Method for producing a container from paper material or paper-like material, having the following steps:
Multi-part container made of paper material or paper-like material, having a lateral surface which is formed from a wound sheet-like segment, of which the lateral segment edges, in the wound state, are arranged in a region of overlap, and having a pan-like termination element, that is to say a pan-like base and/or a pan-like lid, wherein the lateral surface and the termination element are connected in an essentially liquid-tight manner by means of a skirt, wherein, in the region of the skirt, the lateral surface and the termination element are pressed together and sealed to one another, wherein, on a periphery of the region of overlap, an interspace which is formed between the segment edge resting on the outer side of the termination element and that portion of the segment of the lateral surface which rests on the segment edge is completely filled with a sealing material, and in that a pressed-in depression is provided on the inner side of the skirt, in the region opposite the segment edge which rests on the outer side of the termination element.
