Cosmetic bottles fall under the packaging category of daily necessities.
From a practical perspective, cosmetic bottles are primarily used to hold various cosmetics, such as creams, lotions, serums, and perfumes. Their design and function are centered around protecting and storing cosmetics. Like a "shell" for cosmetics, they shield them from the outside world, preventing them from deteriorating and evaporating, and ensuring they maintain their original quality and efficacy throughout use.
In daily life, cosmetic bottles come in a wide variety of materials. Glass bottles offer excellent transparency, allowing consumers to clearly see the contents and conveying a sense of quality, but they are relatively fragile. Plastic bottles are lightweight, cost-effective, and resistant to breakage, making them suitable for large-scale production and transportation, but they may lack in quality and transparency.
