This insulated water bottle is part of Youzhi's Adventure Series for children. Here’s an introduction covering its material, functionality, appearance, capacity, and thermal performance:

1. Material Safety
(1) Inner Material: Made of 316 stainless steel, commonly used in medical and food industries. It has a higher molybdenum content, strong resistance to chloride ion corrosion, and better corrosion resistance than standard 304 stainless steel. It is safe, non-toxic, highly durable, and suitable for children.
(2) Sealing Material: The threaded connection of the lid and the spout are made of food-grade silicone, which is soft, comfortable, and provides an effective seal. It is safe, non-toxic, and poses no health risks to children.

2. Functional Design
(1) Opening Mechanism: Features a press-to-open pop-up lid that can be easily operated with one hand, making it convenient and quick for children to drink.
(2) Leak-Proof Design: Undergoes rigorous sealing tests to ensure it does not leak even when turned upside down 360° under normal use. This prevents water from spilling in backpacks or during activities, keeping books and clothes dry.
(3) Flow Control and Anti-Choke Design: The spout is designed with a soft silicone small round opening to control water flow and prevent children from choking while drinking.
(4) Portability: Comes with an adjustable shoulder strap for easy carrying. It also has a wide, detachable handle for convenient hand-carrying, making it ideal for school commutes or outdoor activities.

3. Appearance Design
(1) Color Variety: Available in multiple colors such as Galaxy Blue, Cute Pink, and Sunrise Orange to suit different children’s preferences.
(2) Capacity Options: Offers various sizes, with 550ml being the most common. Other options include 350ml and 1200ml to meet different hydration needs in various scenarios.
(3) Thermal Performance: Utilizes double-layer stainless steel vacuum technology with an insulating vacuum layer for excellent heat retention.
