Multi-temperature-sensitive color-changing cup and manufacturing process thereof

Abstract

The invention discloses a multi-temperature-sensitive color-changing cup. The multi-temperature-sensitive color-changing cup comprises a cup body, wherein the cup body is provided with a color changing layer, and the color changing layer contains at least two temperature-sensitive color changing powders; a first coating and a second coating are arranged on the color changing layer, and a non-transparent first barrier layer is arranged between the first coating and the color changing layer. The multi-temperature-sensitive color-changing cup has the advantages that the at least two temperature-sensitive color changing powders in the color changing layer can more accurately reflect the temperature range of liquid in the cup body, thereby improving the practicality and the convenience of life;the color changing layer changes when the temperature change reaches a critical value and cooperates with the first coating and the second coating to form a new color pattern, and two or more color pattern changes can be achieved according to the temperature change, thereby greatly improving the interest. A manufacturing process of the multi-temperature-sensitive color-changing cup has the advantage that the first barrier layer, the first coating and the second coating are printed on the cup body where the color changing layer is sprayed through a printing device, thereby conveniently and efficiently achieving the production of the multi-temperature-sensitive color-changing cup. The multi-temperature-sensitive color-changing cup is applied to the field of cup containers.

Description

technical field [0001] The invention relates to the field of cup containers, in particular to a multi-temperature color-changing cup and a manufacturing process thereof. Background technique [0002] The color-changing cup is also called the magic cup. When hot or cold water is poured into the cup, the color of the cup will change. The color-changing cup can provide color changes while holding liquids such as water and wine, which provides fun for single-function cups. And the color change on the cup body can reflect that the temperature of the liquid is in a certain temperature range, so that the user can roughly know the temperature range of the liquid contained in the cup body without tasting or touching it personally. With the development of color-changing cups, color-changing cups with color patterns have gradually entered the market and been widely promoted. At present, the discoloration degree of this kind of color-changing cup with color pattern is relatively singl...

AI Technical Summary

Problems solved by technology

At present, the degree of discoloration of this color-changing cup with color patterns is relatively single, usually for the discoloration caused by a certain temperature.

And in fact, the color-changing cup can only reflect that the temperature of the liquid in the cup is greater than or less than a certain temperature value, and cannot get a more specific actual temperature

Moreover, the color pattern formed by the color change of the current color changing cup is usually relatively single, and its interest is relatively low, so it is difficult to meet people's more changing needs.
