Abstract: 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.

Abstract: 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

Abstract: A sealing tool for sealing a base into a sleeve with a sonotrode and an anvil with an end face, the anvil having a cavity in the end face to accommodate the sleeve and base, the cavity having an inner surface section formed as a first sealing surface, the sonotrode having a section that can be guided into the cavity in a longitudinal direction and has a circumferential surface section formed as a second sealing surface, the sonotrode and anvil being movable relative to each other in a longitudinal direction between a starting position, in which the sonotrode is positioned outside the cavity, and a welding position, in which the sonotrode is positioned inside the cavity so that the two sealing surfaces are arranged opposite each other and a gap for accommodating the sleeve and base remains between the two sealing surfaces, wherein an inner surface section serving as a guide section adjoins the first sealing surface in the longitudinal direction.

Abstract: The present invention relates to a sonotrode for crimping an edge of a container having an end face, which is intended to contact the edge of the container during a relative movement along a longitudinal axis, wherein the end face comprises a crimping portion, at least portions of which form an angle with the longitudinal axis that is greater than 0° and is less than 90°, and the crimping portion is intended to contact the edge being crimped.

Abstract: A tool for an ultrasonic sealing device with a base surface, wherein the base surface has a first elevation which extends from the base surface in a direction perpendicular to the base surface, wherein the first elevation has a first partial sealing surface, wherein the first partial sealing surface has a second elevation which extends from the first partial sealing surface in a direction perpendicular to the first partial sealing surface, wherein the second elevation has a second partial sealing surface. In order to provide a tool with which aluminum-free plastic materials, in particular polypropylene sealing layers, can also be reliably sealed, it is proposed according to the invention that both the first partial sealing surface and the second partial sealing surface are provided for processing a material.
