FIELD: physics, computer engineering.SUBSTANCE: package includes an external structure and a mobile display. The mobile display includes a display tape and a main tape. The display tape is joined to the main tape in a manner that allows scrolling and has a first display surface and a second display surface. The display tape is connected to the external structure through a locking member. The main tape encircles the external structure and can move from a first vertical position to a second vertical position. In the first position the first display surface is visible and the second display surface is hidden. In the second position the first display surface is hidden and the second display surface is visible. Vertical movement of the main tape along the external structure leads to the scrolling of the display tape.EFFECT: improved design.20 cl, 10 dwg |
