Abstract: A screw cap for containers with a threaded neck portion, comprising: a base portion comprising a top surface and a bottom surface, the bottom surface having a center, and an annular portion raised from the base portion. The annular portion has an inner surface and an outer surface. A threaded portion is arranged on the inner surface of the annular portion, the threaded portion having at least one thread, the thread extending from a start into a first circumferential direction around the inner surface, the start being that part of the thread, where the material of which the thread is made, starts to rise from the inner surface.

Abstract: The invention relates to a method for encoding a dimensionally stable packaging container or an associated constituent made of plastics material, wherein the packaging container is suitable for storing consumer goods such as food, detergents, etc., wherein a film-shaped, flat plastics material for forming the three-dimensional packaging container or the associated constituent is deep-drawn using a tool mold while, at a plurality of positions, the outer sides or the inner sides thereof undergo a first shape-changing treatment acting on the first surface thereof for producing a plurality of three-dimensional codes.

Abstract: Method of identifying a packaging material for recycling comprising the steps of: a. Providing a container for packaging a product with a container inherent code; b. Creating an entry in a database associated with the container inherent code, the entry containing at least data on packaging materials used in the production of the container; c. Providing at least one read-out device for reading out the container-inherent code; d. Reading out the container inherent code; e. Retrieving the data of the entry from the database for recycling the container.

Abstract: The invention relates to a device (1) for closing a threaded neck (2) of a container (3) providing tamper-evidence, the device (1) comprising a cap (4) and a plug (5), wherein the cap (4) comprises a front surface (6) and a skirt (7) surrounding the front surface (6), wherein the skirt (7) comprises an inner thread (8) for engaging with a thread of the threaded neck (2) of the container (3), wherein the plug (5) is at least partially arranged inside the skirt (7), wherein the front surface (6) has an inner piece (10) and an outer piece (11) that surrounds the inner piece (10), wherein the inner piece (10) is connected to the outer piece (11) by a connection (12), wherein the connection (12) between the inner piece (10) and the outer piece (11) has a material weakening, wherein the inner piece (10) is in mechanical engagement with the plug (5), the mechanical engagement allowing a force, preferably a rotational force to be transmitted from the inner piece (10) to the plug (5).

Abstract: The invention relates to a method for coding a dimensionally stable packaging container or an associated component made of a plastics-based and/or paper-based material composition, the packaging container being suitable for storing consumer goods such as food, washing agents, etc., wherein, during a shape-forming process for forming the three-dimensional packaging container or the associated component by means of a shaping tool mold, at least one outer and/or inner side undergoes, in at least one position, a shape-changing treatment acting on its first surface in order to produce at least one three-dimensional code.
