Abstract
Container with counter comprising two cylindrical containers (1, 2) that one is placed coaxially inside the other, two saw-tooth structures (1a, 1b) and two sets of readings (1c, 1d) which are mounted on the outside surface of the inner cylindrical container (1), a window (2a) and a tenon with triangular cross section (2b) which are mounted on the outer cylindrical container (2), a cap (3) and a spring (4). When the container with counter is closed, the inner cylindrical container (1) is pushed in by the cap (3) and when the container with counter is opened, the inner cylindrical container (1) is partially pushed out by the spring (4). Accompanying these processes is a relative motion of the tenon (2b) along the saw-tooth structures (1a, 1b), which rotates the inner cylindrical container (1) and thus changes the reading shown from the window (2a). Alternatively, especially for large containers, a cylindrical structure ( 5) which replaces the inner cylindrical container (1), together with the saw-tooth structures (1a, 1b), the readings (1c, 1d), and the spring (4), is placed coaxially inside the cap (3). The saw-tooth structures (1a, 1b) are mounted on the outside surface of the cyl…
