Degradable and recyclable double-mounted straw for beverage packaging

Abstract

The invention provides a degradable and recyclable double-mounted straw for beverage packaging. The degradable and recyclable double-mounted straw comprises a silica gel plug, an external straw chute,an external straw, an internal straw guiding shaft, an internal straw and a valve-like port; and the silica gel plug includes a soft plug and a cover film, the soft plug is in seal fit with the external straw, the external straw and the internal straw are embedded in a sleeving manner, and the external straw chute and the internal straw guiding shaft achieve relative movement. The degradable andrecyclable double-mounted straw has the beneficial effects that the machining cost of raw materials can be effectively reduced; meanwhile, the problems of paper straw bending deformation and inner wall adhesion are solved, faster and large-amount suction of liquid is facilitated, the problems that the suction force is insufficient and paper straw dissolving is generated after long-time contact inthe drinking stage are solved, the external straw and the liquid keep separated all the time in the non-drinking stage, and the problem of paper straw dissolving in the non-drinking stage is solved; and environment-friendly circulation of all materials is realized in combination with other multi-angle design, and sorting and recycling are facilitated.

Description

technical field [0001] The invention relates to a degradable and recyclable double-set straw used for beverage packaging. Background technique [0002] In December 2018, the European Union passed the most stringent bill on disposable plastic products in history: from 2021, the use of disposable plastic straws, tableware, cotton swabs and other items will be completely banned and replaced by more environmentally friendly materials. In order to comply with the global "plastic restriction order" upsurge, food and beverage giants such as McDonald's, Starbucks, Diageo, Paul Rica and other companies have successively promised to gradually stop the use of disposable plastic straws, and began to try to use paper straws. However, when in contact with liquid beverages, the paper straws will inevitably be bent and deformed by moisture, the inner wall of the tube will be glued, the suction will be insufficient, and even dissolve, which has aroused strong responses from consumers in term...

AI Technical Summary

Problems solved by technology

[0003] The main purpose of the present invention is to solve the problems of bending deformation, sticking of the inner wall of the tube, insufficient suction, and even dissolution when the environmentally friendly paper straw is in contact with the liquid drink for a long time, and provides a degradable straw for drink packaging.
