Description

Technical Field

[0001] The invention relates to the technical field of cosmetic packaging equipment, in particular to a replaceable needle dropper. Background Art

[0002] Most essences in cosmetics contain both hydrophilic and lipophilic ingredients, which can break down the water and oil in skin care products at the same time, and then be better absorbed by the skin. Essence is generally used after washing the face and applying lotion to increase the skin's absorption, so that the subsequent skin care products can be better absorbed. Essence can soften and moisturize the keratin, making it easier for the stratum corneum to absorb subsequent maintenance ingredients. Since essence is relatively expensive, it needs to be used in a quantitative manner. At present, most of the packaging containers for essences on the market are dropper-type cosmetic bottles.

[0003] However, the existing dropper-type cosmetic bottle has a dropper connected to the bottle cap. When in use, the user squeezes the rubber head connected to the dropper with the thumb and index finger to absorb the liquid in the bottle into the dropper, and then squeezes out the liquid in the dropper for use. This requires the user to frequently squeeze the rubber head with force, which leads to a poor user experience. In addition, due to different forces, the amount of liquid absorbed by the dropper each time is different, making it difficult to quantitatively absorb the cosmetic liquid, which easily causes a certain amount of waste. Moreover, after use, the dropper has nowhere to be kept, and the random placement of the dropper may cause bacteria to enter, causing infection and deterioration of the material. In addition, when the essence in the dropper-type cosmetic bottle is almost used up, the essence at the bottom of the packaging bottle cannot be obtained, which also causes a certain amount of waste.

[0004] In view of the above problems, in order to prevent bacteria from infecting products, reduce product waste, and improve the use efficiency of equipment, the present invention proposes a replaceable needle dropper. Summary of the invention
