The invention relates to an antibacterial high-rigidity round-tube lip gloss and a material preparation method thereof, designed to solve the technical problems of inconvenient assembly and use, poor sealing performance and insufficiently improved preparation materials caused by inferior structural design of existing similar products. The bottle mouth of the round-tube lip gloss is provided with an inner plug, and the stick is provided with a cotton head. The key design is that a protruding fixed ring rib is arranged on the outer diameter of the transition section below the outer rim opening of the inner plug, and a ring groove is arranged on the inner diameter below the bottle mouth of the bottle body. The inner plug is hermetically fastened and fixed with the ring groove of the bottle body through the fixed ring rib respectively. The inner plug tapers from one end of the outer rim opening to the other end via the transition section, and a stepped ring diameter is arranged on the outer diameter at the necked part of the inner plug. A protruding sealing ring rib is arranged at the bottom of the internal thread of the stick head of the stick. When the internal thread of the stick is connected with the external thread of the bottle body, the outer rim opening of the inner plug abuts and fits with the sealing ring rib of the stick, and the edge of the outer rim opening at one end of the inner plug abuts and seals with the bottom ring diameter of the stick head groove of the stick. Some of the above components are made of antibacterial high-rigidity materials.
