[0023] FIG. 1 illustrates a side view of the paper cup according to the invention. In this detailed description, the paper cup according to the invention is explained only for a better understanding of the object and without restrictive effect. The invention relates to a paper cup which can be used in vending machines, preferably for use in hot and cold areas for beverages, and each cup has a circumferential groove on both its inner surface and its outer surface.

[0024] When the paper cup 1 of the present invention is put in a second cup 2, the outwardly convex groove 4 on the first cup 1 and the inwardly convex groove 3 on the second cup 2 will hook with each other and hold their position as long as no external force is applied. The groove structure of the paper cup according to the invention enables two or more inventive products to be used by nesting them.

[0025] The basic principle of the paper cup according to the invention is that the outwardly curved groove 4 on the outer surface of the first paper cup 1 on the inside of the inwardly curved groove 3 of the inner surface of the second paper cup 2 hook or jam and maintain their position as long as no external force acts.

[0026] The paper cup according to the present invention is obtained by the following process steps:

[0027] 1. Cutting and printing the cardboard in the demanded.

[0028] 2. Shape the cut piece into a paper cup shape.

[0029] 3. Applying the groove system to the cardboard, which has been made into a paper cup shape.
