The following is the optimized design case of D35-24 thread center dispensing cap:

The design scheme designed as above:

Inner cap: transparent PP material

Outer cap: Translucent PP material

In order to improve the texture of the surface of the cosmetic cap, the outer cap electroplating process is adopted;

This increases the cost for processing and pollutes production and recycling.

The design scheme designed as above:

Inner cap: transparent PP material

Outer cap: Translucent PP material

In order to improve the texture of the surface of the cosmetic cap, the outer cap electroplating process is adopted.

This increases the cost for processing and pollutes production and recycling.

As shown in the figure above, the optimized design:

Inner cap: still using transparent PP material

Outer cap (two-color cap): The inner layer of the cosmetic cap is made of PP raw material, and the outer layer is made of TPE/TPR elastic plastic with PP as the base material;

The outer cap is molded by two-color injection mold in 2 times, so that the cosmetic cap has 2 color combinations, and the unique shapes, patterns, logos and other design elements can be matched to avoid the material loss caused by 2 times of processing, and the surface is finely frosted. The effect is to achieve the effect of improving the surface texture, and at the same time avoid the pollution caused by electroplating to the environment.

Since the outer layer is made of TPE elastic plastic, it can increase the touch feeling and achieve a silky feeling similar to the skin. When the customer uses the cosmetic cap, there will be a good touch feeling.

Through design improvement, cosmetic caps can be crushed and recycled as a whole. Since the entire cosmetic cap is made of PP base material, it can be used in PP products after recycling. It has a good surface effect when it reaches the appearance of cosmetic caps, and at the same time achieves the purpose of environmental protection.

 Zetoo has been committed to the two-color injection molding of cosmetic caps for many years, and has independently developed a variety of two-color caps. At the same time, it provides customers with technical support services for two-color caps and innovative bottle types.
