SUBSTANCE: vane lug (10) for can opening can be separated from the can, and can be safely carried in the pocket due to its smooth rounded edges and compactness. The vane lug (10) for can opening is rather large and excludes its fall in the beverage can after separation, that otherwise can result in danger of asphixia and injury. The vane lug for the cans opening has U-shape raised edge (10C), ensuring finger insertion for more easier can hole opening. U-shape raised edge (10C) of the vane lug for the cans opening can also have jumper for nose ensuring the beverage drinking just from the can without the necessity of too far head overturn.

EFFECT: the lug for cans opening has vane shape and sufficient width and height for the arrangement of advertising, logos, slogans, conditions of competition, graphics, web-sites, stamping or other marketing, advertising or informative messages focused on the beverages user.

SUBSTANCE: invention proposes a printing material with a thermally transferred pattern for the protection against forgery, a special foil for thermal transfer and a manufacturing method of such a printing material. The method involves the following stages: arbitrary application of fibres on foil with an adhesive so that the foil for thermal transfer can be obtained; scanning and receiving the information characterising arbitrary distribution of the fibres; and storage of specific information in a data base of a computer-aided system of requests for the protection against forgery, which is connected to a telephone network and/or the Internet for public familiarisation and check of authenticity. By using the applicable methods and equipment for thermal transfer, the manufacturer of the printing material can manufacture the printing material with the protection against forgery, which has a local pattern, by means of thermal transfer with the thermal transfer foil. This invention makes a break-through in the area referring to the "pattern" in the existing state of the art and proposes one more new technical measure for the protection against forgery using fibres.

EFFECT: this invention saves enormous investments in special equipment, simplifies the production process, improves the production efficiency and reduces production costs.
