. Because the outer figure or design (not shown) on the cup is fixed, the user may easily tire looking at a fixed figure. Because there is no heat insulation in a conventional cup, the fluid contained in a conventional cup will deteriorate due to the influence of external temperature.
SUMMARY OF THE INVENTION
The primary objective of this invention is to provide a three-dimensional rotating cup that combines aesthetics and fun while maintaining its practicability.
The secondary objective of this invention is to provide a three-dimensional rotating cup with an exterior view of changing figures.
To achieve the above objectives, the 3-dimensional rotating cup is characterized as follows: An interior fixed cup is placed inside an exterior fixed cup; an interior rotating layer and an exterior rotating layer are placed inside the interior and exterior fixed cups with a transparent fluid filling the inside of the clearance between the interior and exterior fixed cups; furthermore, extending outwardly from the edge of the interior fixed cup is a protruding flange; the bottom of the protruding flange is joined to the top of the edge of the exterior fixed cup.
