Abstract
A color-changing container with two-dimensional and/or three-dimensional pattern is disclosed, which comprises a container body and at least one two-dimensional and/or three-dimensional pattern film. The material for making the container body is mixed with a thermochromic powder, a photochromic powder or the combination of thereof, making the color of the container body change along with the temperature change of the content or the brightness change in the environment. The two-dimensional and/or three-dimensional pattern film comprises a grating layer set on one surface of a transparent layer, and a pattern area printed partially on the other surface of the transparent layer and coated by a glue layer. Therefore, after the two-dimensional and/or three-dimensional pattern film is combined to the container body, the container body is not only has the effect of color change, but also has the different pattern changes in different angle or layer of the two-dimensional and/or three-dimensional pattern.
