50ML straight round water bottle（坤-50ml-B426）

This bottle features a 50ml capacity, designed with smooth and rounded shoulder lines and a slender body. It is equipped with a 24-thread all-plastic lotion pump paired with a full cover. The pump components include an outer cover made of AS (Acrylonitrile-Styrene copolymer) or MS (Methyl Methacrylate-Styrene copolymer), a button, a middle holder crafted from PP (Polypropylene), a gasket, and a suction tube made of PE (Polyethylene). This well-structured packaging solution is highly suitable for containing various products such as lotions and essential oils.

The 50ml capacity is carefully determined to balance portability and product quantity, making it an ideal choice for both daily home use and travel scenarios. Users can easily carry it in handbags, suitcases, or cosmetic bags without taking up excessive space, while the capacity is sufficient to meet short-term or regular usage needs of lotion, essential oil, and other similar products.

In terms of appearance design, the rounded shoulder lines break the rigidity of traditional bottle shapes, adding a sense of softness and elegance to the overall look. This design not only enhances the aesthetic appeal of the product but also improves the grip experience—when held in the hand, the smooth shoulder transition fits comfortably with the palm, avoiding the discomfort caused by sharp edges. The slender bottle body further accentuates the delicate and minimalist style, which is in line with the current mainstream aesthetic trends in the cosmetics and skincare packaging industry, easily attracting the attention of consumers.

The 24-thread all-plastic lotion pump is a core component of this packaging system, with its thread specification ensuring a tight and secure connection with the bottle mouth, effectively preventing product leakage. The selection of materials for each part of the pump is based on strict quality and safety standards: AS/MS outer cover offers excellent transparency and impact resistance, allowing consumers to clearly see the internal pump structure while ensuring durability; the PP middle holder has good chemical resistance and mechanical strength, providing stable support for the pump’s operation; the PE suction tube features good flexibility and corrosion resistance, which can closely fit the bottle body to ensure that the product can be fully pumped out without residue; the gasket plays a key sealing role, preventing air from entering the bottle and the product from oxidizing or deteriorating due to contact with air.

In addition to lotions and essential oils, this bottle can also be applied to other liquid or semi-liquid products such as hand creams, serums, facial masks, and body oils. Its versatile design and reliable performance make it a practical and cost-effective packaging option for brands in the cosmetics, skincare, and aromatherapy industries. The all-plastic material of the pump and the bottle body also conforms to the environmental protection requirements of many regions, as it can be recycled and reused after proper treatment, reducing the impact on the environment.
