[0001] The utility model relates to a dispensing bottle, in particular to a dispensing bottle with a self-sealing structure. Background Art

[0002] Many people need to carry cosmetics and skin care products when they are on business trips or traveling. The original bottles are large and inconvenient to carry, so the various lotions in the original bottles are usually divided into sub-bottles.
