Abstract
This utility model relates to the field of lipstick tube technology and discloses a convenient lipstick tube, including a rigid elastic tube body and a soft elastic tube body. The rigid and soft elastic tube bodies are formed by secondary injection molding. The length of the rigid elastic tube body is shorter than that of the soft elastic tube body. An integrally formed dispensing nozzle is provided at the top of the soft elastic tube body. An integrally formed elastic one-way valve is provided inside the dispensing nozzle. The secondary injection molding structure of the rigid and soft elastic tube bodies, and the design that the length of the rigid elastic tube body is shorter than that of the soft elastic tube body, make the dispensing part at the top more flexible, allowing users to apply force more easily when squeezing. The overall structure is stable, and the connection between the dispensing nozzle and the elastic one-way valve and the soft elastic tube body is tight, making it less likely to fall off or be damaged, thus improving the durability of the product.
