50ml round chubby curved-bottom lotion bottle LK-RY116 （悠-50ML-D6）
This container features a 50ml capacity bottle design with a moderately sized body that strikes an ideal balance between portability and product storage. The bottle’s base adopts a smooth arc-shaped structure, which not only enhances the overall aesthetic appeal by softening the container’s 轮廓 (silhouette) but also improves stability—effectively preventing the bottle from tipping over easily when placed on flat surfaces such as dressing tables or bathroom counters.
In terms of component configuration, the container is equipped with a 20-thread high-profile middle collar (referred to as “中束” in the original text), consisting of multiple high-quality materials to ensure both functionality and durability. The collar itself is made of double-layered PP (polypropylene), a lightweight yet robust plastic material known for its excellent chemical resistance—critical for preserving the purity of serums, essential oils, and other skincare products. Complementing the collar is a silicone rubber cap, which provides an airtight seal to prevent oxidation and moisture intrusion, thus extending the product’s shelf life. Additionally, a PE (polyethylene) double-laminated gasket is integrated into the design; this food-grade, non-toxic component adds an extra layer of protection against leakage, ensuring the container remains mess-free during transportation or daily use. The assembly is completed with a 7mm round-tip low borosilicate glass tube—borosilicate glass is chosen for its high thermal resistance and resistance to chemical corrosion, making it safe for direct contact with concentrated formulas like essential oils. To further optimize usability, a 20-thread PE guide plug is included; this plug helps align the glass tube and collar during assembly, simplifying the production process while ensuring consistent quality across each unit.
Beyond its functional advantages, this container can be paired with appropriate decorative crafts to elevate its visual appeal. For example, custom silk-screen printing or hot stamping can be applied to the bottle body to add brand logos or aesthetic patterns, while metallic accents on the cap can create a luxurious look. Such customization not only enhances the container’s beauty but also helps brands stand out on store shelves, attracting consumer attention. Whether used for high-end serums in a boutique skincare line or pure essential oils in a wellness brand, this container seamlessly combines aesthetic charm and practical functionality—meeting the dual demands of both consumers and manufacturers for quality, safety, and visual appeal.
