Description

Sealing device for cosmetic liner Technical Field The application relates to the technical field of product packaging, in particular to a sealing device for a cosmetic liner. Background In the product packaging industry, the sealing device of the cosmetic liner is used for accommodating cosmetics, but the existing sealing device has various defects in structural design, so that the sealing effect and stability of the sealing device are poor. The sealing element and the chassis in some sealing devices are relatively simple in matching mode, sealing is usually realized by means of a single contact surface or a compression mode, gaps are easily generated when external pressure changes, vibration or temperature fluctuation occur, sealing failure is caused, the contact area of the sealing element of other sealing devices is small, the sealing ring is easily deformed after being impacted by external force or aged by materials, sealing performance is rapidly reduced, the sealing effect depends on assembly precision, and leakage of cosmetics is likely to be formed by slight deviation. Disclosure of Invention The object of the present application is to provide a sealing device for a cosmetic liner, which aims at least one of the above-mentioned existing technical problems. Through being provided with sealed inner circle and fixed inner circle on the lateral wall of sealing ring, the sealing ring can with the chassis lock, and then promotes sealing device's sealed effect. The application provides a sealing device of a cosmetic liner, which comprises a chassis and a sealing ring; The sealing ring is used for being buckled with the chassis, the sealing ring comprises an inner side wall and an outer side wall, a sealing groove is formed between the inner side wall and the outer side wall, the chassis comprises a sealing convex edge, and the sealing groove can be matched with the sealing convex edge; The outer side wall is provided with a sealing inner ring and a fixing inner ring, the outer edge of the sealing inner ring and the outer edge of the fixing inner ring are protruded out of the outer side wall, the sealing inner ring can be matched with the side wall of the sealing convex edge, and the fixing inner ring can be clamped with the groove on the side wall.
