Technical Field
[0001] This utility model belongs to the technical field of nail polish containers, specifically relating to an improved nail polish bottle. Background Technology
[0002] Nail polish is a functional product widely used for decorating fingernails or toenails. It comes in a variety of vibrant colors and offers both aesthetic appeal and protection. Currently, nail polish is packaged in bottles with caps containing a rod that inserts into the bottle body. The end of the rod typically has bristles for applying the nail polish to the nails.
[0003] Currently, standard nail polish bottles generally consist of a bottle and a cap, and come in various shapes. However, nail polish is volatile, and if the cap is not properly closed after use, the seal is poor, and the odor can easily escape. Therefore, adding a sleeve to the outside of a standard nail polish bottle would enhance the seal, improve the appearance, and be more convenient.
