How to design lipstick cases to achieve efficient anti-seismic function?

Lipstick cases usually use materials with a certain degree of elasticity to enhance their anti-seismic performance. These materials include but are not limited to silicone, sponge, EVA (ethylene-vinyl acetate copolymer) foam and memory foam. These materials can absorb and disperse energy when impacted by external forces, reducing the vibration and impact force on the lipstick.
The internal structural design of the lipstick case also plays a key role in its anti-seismic performance. In a lipstick case with a multi-layer or partitioned design, each layer or partition area is carefully designed to ensure the stability and safety of the lipstick in it. For example, there may be a special groove or fixture inside the lipstick case to fix the position of the lipstick to prevent it from shaking or colliding with each other in the box. In addition, the bottom and sides of the lipstick case may also be designed with shock-absorbing pads or buffer layers to further enhance its anti-seismic performance.
In addition to the design of materials and internal structures, the sealing between the lid and the body of the lipstick case also has an important impact on the anti-seismic performance. A tightly sealed lipstick case can effectively reduce the impact of external vibration on the lipstick. To achieve this goal, the lid of the lipstick box is usually designed with a lock, magnetic or elastic snap to ensure a tight fit between the lid and the box body.
During the design and production process of the lipstick box, a series of seismic tests and verifications are usually carried out. These tests may include simulating vibrations and shocks during transportation, as well as simulating various situations that consumers may encounter when using the lipstick box. Through these tests, it can be ensured that the lipstick box has good seismic resistance in actual use and can protect the lipstick from damage.
The seismic function of the lipstick box is achieved by selecting seismic-resistant materials, designing a reasonable internal structure, ensuring a tight seal between the lid and the box body, and conducting seismic tests and verifications. These measures work together to ensure that the lipstick can remain intact when experiencing various external shocks and vibrations, extending its service life.
