cap

Abstract

<About the color> - This item changes color at the same temperature as the heatstroke alert (33°C) issued by the Ministry of the Environment and the Japan Meteorological Agency, and can be used as a bottle cap to notify people when to drink fluids. Examples of color changes include brown to yellow, green to yellow, orange to yellow, purple to blue, and blue-purple to pink. (More materials may be added.) <About the shape> - It can be hung, wall-mounted, hooked, and weighed. After washing, the hanging function allows for hygienic drying. The uneven surface makes it easy to open and close, even for those with limited strength. - The tapered bottom of the cap protects the drinking spout from dirt. - Decorative additions could also be used in industrial applications.
