[0002] Balm is usually a semi-solid fragrance product, widely used in daily chemical fragrances. Its unique physical state makes it easy to carry and use. Balm is usually made of plant exudates or resins, with unique fragrance and fragrance retention characteristics. The viscosity of the balm allows it to slowly release the fragrance, thereby prolonging the fragrance retention time. Balm can be used in various ways. It can be applied to multiple parts of the body, such as behind the ears, inside the wrists, etc., to emit fragrance and moisturize the skin.

[0003] Balm cylinders are cylindrical containers used to package balm products. They are a common form of packaging for cosmetics, medicines and other daily necessities. They have good sealing properties and are easy to carry. As an important packaging form for balm products, balm cylinders not only protect and store products, but also directly affect consumers' experience and brand image. Existing balm cylinders do not have a replacement function. When the balm in the balm cylinder is used up, the cylinder can only be discarded, increasing the environmental burden. In addition, the rotating seat of the base cannot be separated from the inner cylinder where the balm is placed, and the inner cylinder cannot be replaced. Summary of the invention
