AI Technical Summary

Technical Problem

The existing paper cup has a simple structure and poor thermal insulation and insulation performance. At the same time, water in the paper cup is easily spilled out during the movement, causing burns from the user.

Method used

A double-layer thermal insulation paper cup is designed, with multiple reinforcement plates evenly arranged between the inner liner and the shell. An anti-scalding structure is set on the outside of the shell, a cup edge and a baffle are set on the top of the inner liner and the shell. A water leakage hole is opened on the outside of the baffle, and a cup bottom is fixed on the bottom of the shell.

Benefits of technology

The reinforcement plate between the inner liner and the outer shell improves the insulation and deformation resistance to prevent water from leaking; the anti-scalding structure and baffle prevent water from splashing, and avoids burns from users.

Abstract

The utility model relates to the technical field of paper cups, and discloses a double-layer heat preservation and insulation paper cup which comprises an inner container, a shell sleeved on the outer side of the inner container, a plurality of reinforcing plates evenly arranged between the inner container and the shell, an anti-scalding structure arranged on the outer side of the shell, a cup edge arranged on the top of the inner container and the top of the shell, and a baffle arranged on the inner wall of the cup edge. When the cup is used, an inner cavity is formed between the inner container and the shell, the heat preservation performance of the inner container and the shell is improved, meanwhile, a plurality of reinforcing plates are evenly distributed in the inner cavity, the deformation resistance of the inner container and the shell is improved, the situation that the inner container and the shell are deformed, and consequently water leaks is avoided, and the service life of the cup is prolonged. And meanwhile, in the moving process, the flushing baffle can shield splashed water, and the situation that the water is splashed out, and a user is scalded is avoided.
