Each protruding tooth structure of the first internal threads is provided with first and second inclined surfaces located on two sides of the protruding tooth structure with a recessed structure between two adjacent protruding ones. The first inclined surface faces the fixing part. Within a same cross section through the mouth part's axis, the bottom of the recessed structure has a tangent parallel to the mouth part's axis, angle α between the first inclined surface and the tangent is 110°-145°, and angle β between the second inclined surface and the tangent is at least 90°. The cutting element is sleeved in the mouth part with first external threads.

A sealing station configured to heat seal a wall made from heat-sealable film material, preferably metal-free heat-sealable film material, onto one another wall of heat-sealable material, e.g. another wall of heat-sealable film material, to create a sealed seam. The sealing station comprises an impulse sealing device comprising a first jaw and a second jaw, wherein at least the first jaw comprises at the respective front surface thereof at least one, e.g. a single elongated, impulse heatable member that extends along the respective front surface and that is covered by a heat-resistant non-stick covering.

Described and depicted is an application apparatus for applying additional elements, in particular straws, to packages, preferably cardboard composite packages. So that the application can also be carried out reliably at high speeds and with moderate equipment complexity, it is provided that at least two applicators are provided which are adjustable along a common, circumferential transport track from a pick-up position for picking up the additional elements to an application position for applying the additional elements to the packages and back and which comprise respectively at least one application finger for pressing the additional elements onto the packages.

The present invention relates to a liquid-tight container comprising a container wall which surrounds a container interior at least in part, wherein: a jacket element and a first end element are connected to one another and each form a portion of the container wall; wherein the jacket element delimits the container interior in a transverse direction extending from the inside to the outside in relation to the container interior, and comprises a rim portion having a first edge; wherein the first end element delimits the container interior at a first end of the liquid-tight container in a longitudinal direction extending along the length of the container, and comprises a further edge which points in the longitudinal direction; wherein the rim portion a. is located at the first end of the container, and b. encloses the further edge counter to the transverse direction from the outside to the inside in such a way that i. the first edge of the jacket element points counter to the longitudinal direction, and ii. the liquid-tight container comprises, at the first end in the transverse direction, a ply sequence comprising A. a first ply of the jacket element, B. a ply of the first end element, and C. a further ply of the jacket element; wherein the rim portion comprises, at least on a side pointing inwards counter to the transverse direction, a plurality of portions of a first type and a plurality of portions of a further type, which portions differ from one another in their thickness in the transverse direction. The invention also relates to a precursor for producing the liquid-tight container, to a method for producing a liquid-tight container, to the use of a liquid-tight container, and to the use of an ultrasonic generator and/or an ultrasonic sonotrode.

The invention relates to a container comprising a container wall at least partially enclosing a container interior, and a first joining element; wherein a jacket element and a first end element each form a region of the container wall; wherein at least one first plane running parallel to the length of the container through the container interior comprises a first joining layer sequence, over the entire lateral extent of which, with respect to the first joining layer sequence, the jacket element, the first joining element and the first end element directly follow one another as layers; wherein the first joining element has a first surface contacting the first end element and a second surface contacting the jacket element; wherein an imaginary first straight line connects both end points of a first line formed in the at least one first plane by the first surface and lying within the first joining layer sequence; wherein an imaginary second straight line connects both end points of a second line formed in the at least one first plane by the second surface and lying within the first joining layer sequence; wherein the first straight line forms a first acute angle with the second straight line. The invention further relates to methods and a device for the production of the container and to uses of the container, of a sheet-like composite and of joining tools.
