A pouring element for a package having a base body, a polyhedrally formed flange, the flange inner surfaces of which converge in face abutments, for joining to a package sleeve and at least one holding element projecting on the inside of the flange for operatively connecting to a mandrel of a packaging machine, as well as a pouring element with polyhedrally formed gable surfaces, which are correspondingly joined to the polyhedrally formed flange. Provision is made for the holding element to be formed as a rounding in the area of the face abutments on the inside of the flange, in order to prevent the pouring element from becoming damaged during the whole joining process with the package sleeve when putting the pouring element onto, holding it on and removing it from the mandrel and additionally in order to guarantee a secure and precise hold.

Pouring element for a package and composite package having such a pouring element

A pouring element for a package having a base body, a polyhedrally formed flange which is designed for joining to a package sleeve and whose joining faces converge in face abutments, as well as a pouring element for a package, in which the package sleeve is correspondingly joined to the pouring element. Provision is made for receiving areas to be formed in the area of the face abutments for the fold line of the package sleeve ears, in order to prevent the package from becoming damaged during the joining process between the pouring element and the package sleeve and during the folding of the package sleeve ears and hence keep it leak-tight.

A device for liquid-tight sealing of two partially overlapping packaging components. One of these is a tubular basic body. A further packaging component forms the packaging head or bottom, having at least one mandrel and one die. For the tubular basic body to be easily slid on to the mandrel and removed the expansion elements have sealing jaws which, in their working position, form a closed, encircling outer contour.

Device and method for liquid-tight sealing of two partially overlapping packaging parts and containers Produced therewith/thereby

A device and method for the fluid-tight sealing of two partially overlapping packaging components, one being a tubular base member formed from a blank of composite cardboard/plastics material, and an additional packaging component forming the upper packaging portion or packaging base, having at least one mandrel and one die, the mandrel having at least two expansion elements which are moved from the operating position thereof towards each other into a rest position, the expansion elements having sealing jaws which, in the operating position thereof, form a closed circumferential outer contour, which corresponds to an inner contour formed by an opening in the die, there remaining between the inner contour and outer contour a narrow annular gap in order to apply a pressing force from the inner side to the overlap region of the packaging components.
