Abstract: The invention relates to a lid (2) for closing a cup (1) along a peripheral sealing edge (10). Said lid comprises at least one aluminum film and an optionally multi-layered plastic layer which is co-extruded onto the aluminum film and has a closed predetermined tearing line (3). The invention is characterized in that the plastic layer is made of plastic based on polyethylene (PE) or plastic based on polypropylene (PP) and that the predetermined tearing line is introduced into the plastic layer preferably by means of a CO2 laser. In one embodiment, said predetermined tearing line (3) is provided directly in the region of the sealing edge (10). The invention also relates to a method for producing such a lid.

Abstract: The invention relates to a fired refractory ceramic product. According to the invention, this generic term encompasses both shaped and unshaped products. Shaped products are ones which have a defined shape so that they can be manufactured in finished form on the premises of the manufacturer. Shaped products include: bricks, nozzles, tubes, stoppers, plates, etc. The term unshaped products includes ones which are usually produced by the user from a corresponding composition. They include bases for furnaces which are cast from a composition but also repair compositions, etc.

Abstract: The invention relates to a process for producing a carrier material with at least one hidden identification mark which is attached in at least one surface region of the carrier material and which is then covered. The invention furthermore relates to articles containing this carrier material and its use for analysis of the identification mark(s). By the process as claimed in the invention a carrier material with hidden identification marks is made available, the use of which is given in a wide range, especially when the original state of goods is to be established. For the consumer itself the identification mark is not necessarily visible so that he is not unnecessarily upset, but rather is confronted with a conventional decoration, specifically an embossing pattern. If necessary, such as for example in customs controls, the identification mark however can be easily exposed by depression so that analysis of the packaged product with respect to originality can take place.

Abstract: The invention relates to an elongated stopper device for flow control of molten metal, i.e., for controlling the flow of molten metal from a metallurgical vessel, such as a tundish.

Abstract: Products, especially masses and shaped parts with fire-resistant (refractory) qualities when used in an authorized application, are used in particular in devices for receiving, treating and/or transporting melts. Such melts can be steel melts (ferrous melts), non-ferrous melts (such as copper melts) as well as glass melts or rock melts, whereby such melts customarily have temperatures between 1000° C. and 2000° C. According to the invention these refractory products are used to amend the corresponding melt.

Abstract: An element (1) punched out in a cover shape, for sealing of containers (7), includes a first ply (2) and a second inner ply (3) which is provided with a heat-sealable layer (5) on its side facing the container. The plies (2, 3) are connected to one another over their surface sides (2?, 3?.) facing one another by a cold-sealing layer (4), the adhesion between the plies (2, 3) being lower than that between the inner ply (3) and the container edge (8). On the inner ply (3) there can be scoring (10) which is exposed by peeling off the outer ply (2). If for example packaged material which is suited for heating in a microwave oven is stored in the container (7), the steam which forms during heating can escape through the scoring (10).

Abstract: A thermally-sealable multilayer film, for packages which may be resealed after opening, includes an outer layer and a support layer, with a thermally-sealable layer on the side facing the packaged material. A self-adhesive layer made from pressure sensitive adhesive is provided between the support layer and the outer layer. The support layer has weakening lines, which define an opening for the removal of packaged material. For resealing a container, by using the thermally-sealable multilayer film, the user may simply open the defined opening for removal of the contents of the container, by application of an opening force and then reseal the container, by pressing the opened outer layer on to the self-adhesive layer. The above process may be repeated several times, until all the contents of the container are used, whereby the above are protected from possible contamination.

Abstract: The present invention pertains to a packaging element comprising a supporting material fitted, on its face turned opposite the package, with a layer presenting a marking area and, on its face turned to the package, with a rough surface coating. The coating roughness has a depth of 1 to 100 &mgr;m, which can be obtained by using granulous filling material. The rough surface packaging element is suited as a covering element, including for yoghurt, as well as in the production of labels for bottle finishes.
