External spring design: How to effectively avoid contact with harmful substances and improve packaging safety

1. Potential risks of metal springs in traditional packaging
Traditional vacuum bottles usually use built-in springs as pumping mechanisms. This design can ensure the extraction of the contents in the bottle to a certain extent. However, the direct contact between the metal spring and the liquid in the bottle may cause a series of problems. First, after the metal material comes into contact with the liquid components, a chemical reaction may occur, resulting in an adverse reaction between the metal components and the components in the product.

2. External spring design: Isolating the contact between metal and liquid
The innovation of the replaceable airless bottle lies in its external spring design. Unlike the traditional built-in spring design, this bottle type moves the spring device to the outside of the bottle body, completely avoiding direct contact between the metal spring and the liquid in the bottle. The external spring structure effectively isolates the potential chemical reaction between the components in the bottle and the metal material, preventing the metal from contaminating the contents.

3. Improve product safety and reduce consumer risks
Traditional bottle design, especially in low-quality packaging materials and designs, may lead to chemical instability of the product. The design of the external spring maximizes the safety of the packaging and ensures the safety of consumers during use. The external spring structure not only ensures that the ingredients in the product are not contaminated, but also avoids the release of harmful substances caused by factors such as metal corrosion, and avoids allergies or skin discomfort that may occur during consumer use.

For skin care products, the effect of the product directly depends on the stability of its ingredients, especially active substances such as plant ingredients, vitamins and enzymes. These ingredients are very sensitive to air, temperature, humidity and chemical reactions. Therefore, the design of the replaceable airless bottle can effectively isolate the external environment and prevent external factors from affecting the effectiveness of the product, thereby ensuring that the product can maintain the effect during use.

4. Double protection of environmental protection and safety
In addition to avoiding direct contact between metal and contents, the external spring design of the replaceable airless bottle is combined with its environmental protection design, reflecting the new development direction of the packaging industry. The external spring structure can not only effectively isolate the contact between metal materials and the contents of the bottle, but also reduce the harmful chemicals that may be used in the traditional spring internal structure.

In addition, the bottle body of the replaceable airless bottle uses PCR material, which is an environmentally friendly material that can effectively reduce pollution to the environment and also provides a platform for brands to demonstrate social responsibility. Whether in terms of the choice of raw materials or the overall design of the packaging, this bottle type minimizes the negative impact on the environment while ensuring the harmlessness of the packaging and the safety of consumers.

5. Extend the shelf life and efficacy of the product
The replaceable airless bottle also plays an important role in extending the shelf life of the product by avoiding the impact of metal on the contents through the external spring design. Since the metal spring is no longer in direct contact with the liquid ingredients, the active ingredients in the product can be stored for a long time in a more stable and safe environment, avoiding the degradation of ingredients caused by chemical reactions
