Recycling dietary straw

Abstract

The invention discloses a recycling dietary straw, this dietary straw comprising a hard rubber tube portion and a soft rubber tube portion. The hard rubber tube portion and the soft rubber tube portion are connected head to tail. The joints between 1-1 and 1-2 is sealed. The dietary straw can bend along the soft rubber tube portion to make the dietary straw in a folded state. The invention further discloses a special storage box, which can store the dietary straw. The outside wall of the dietary straw is sprayed with an anti-oxidation layer, well the anti-oxidation layer is sprayed with a photocatalyst layer. The invention adopts recyclable materials to provide a convenient, safe and reusable dietary straw.
