1. Material level and safety
Food Grade Stainless Steel (304/316)
304 stainless steel: Basic food-grade material, good corrosion resistance, suitable for holding room temperature water or weak acidic beverages, but long-term exposure to strong acid (if juice or carbonated beverages) still has a slight risk of metal precipitation.
316 stainless steel: upgraded version of food-grade material, adding molybdenum elements to improve corrosion resistance, can withstand higher concentrations of acidic liquids, suitable for long-term use and better safety.
Non-food grade stainless steel (201, etc.)
It is easy to precipitate heavy metals such as manganese and nickel, especially in high temperature or acidic environments, which may cause health risks and must be strictly avoided.
2. Insulation performance and structural design
Single-layer stainless steel cup
Advantages: Lightweight, low cost, suitable for room temperature or short-term insulation needs6.
Disadvantages: No heat insulation layer, easy to burn when installing hot water, and short insulation time (about 2-3 hours).
Double-layer vacuum stainless steel cup
Advantages: The vacuum insulation layer can extend the insulation time (hot water for 6-12 hours, cold water for more than 24 hours), and has better anti-scalding performance.
Disadvantages: Larger weight and higher price.
3. Differences in applicable scenarios
Daily household use
Recommended model: 500ml-1L capacity, direct drinking cup with leak-proof design, 316 stainless steel is preferred.
Outdoor/Commuter
Recommended models: double-layer vacuum cup (fall-proof design), portable hook or cup cover accessories to avoid choosing open and spillable styles.
Special drink demand
Acidic liquids (juice, coffee): 316 stainless steel cups must be used and cleaned in time after each use to avoid residual corrosion.
High temperature liquid: Double-layer anti-scalding cups are preferred to reduce the risk of excessive surface temperature.
4. Key points of health and maintenance
Cleaning Specifications
Avoid using strong oxidative cleaners (such as bleach, soda) to prevent chemical reactions with stainless steel.
Soak it regularly in white vinegar to remove scale to prevent bacteria from growing.
Tare for use
Do not store high salt or strong acidic liquids (such as soy sauce, lemon juice) for a long time to avoid accelerating metal precipitation.
Avoid heating of the microwave. Stainless steel material will reflect microwaves and cause damage to the equipment.
5. Price-performance options
If you need high cost performance, you can choose 304 stainless steel single-layer cups, which are suitable for basic needs.
Pursuing higher quality You can choose a double-layer vacuum cup, with more reliable material and craftsmanship.
Tips Avoiding Tips
Check the "SUS304/316" logo on the bottom of the cup or label, and be wary of fuzzy publicity that is only marked "stainless steel".
You can also prefer a design with silicone sealing ring and anti-slip bottom pad to improve use safety.
1. Core material selection
Priority 304 or 316 stainless steel
304 stainless steel: Complies with food grade standards (including 18% chromium + 8% nickel), safe in daily use and cost-effective, suitable for filling coffee, tea and other regular drinks.
316 stainless steel: Add 2% molybdenum, which has stronger corrosion resistance. It is suitable for long-term acidic beverages (such as lemonade, ice American), but the price is higher than 304.
Tips for avoiding pits: The inner liner must be clearly marked "SUS304" or "SUS316". Beware that low-priced products are used to impersonate 201 stainless steel (high manganese content and prone to rust).
Material process verification
Observe whether the surface is smooth and burrs free, and the inner liner has no seams to reduce dirt residue.
Simple test: The magnet has weak adsorption power (low iron content) or is soaked in salt water for 24 hours without rust spots, indicating that the material is purity .
2. Insulation performance and design
Vacuum insulation technology
The double-layer vacuum structure can block heat transfer and the insulation duration ranges from 8-24 hours. Mirror electrolysis process has longer insulation.
Small-diameter cup shape has better insulation effect than wide-diameter cup.
Cup mouth and capacity design
Commuting/Office: Choose 300-500ml lightweight model, paired with one-handed open cover or anti-slip bottom pad.
Outdoor/Home: Large capacity model above 800ml, with a strap or an anti-slip handle more practical.
Cleaning convenience: Wide-mouthed cups are easy to clean but quickly dissipate heat. Narrow-mouthed cups need to be removed and cleaned regularly.
3. Safety and usage details
Sealing detection
Inverting to test whether water leakage is required, the silicone sealing ring needs to be replaced regularly.
The press-type cup lid is suitable for driving scenarios, and the knob is suitable for office scenarios.
Avoid storing drinks
Acidic liquids (such as lemon juice, carbonated beverages): may corrode the inner liner of non-316 material.
Dairy products (milk, soy milk): It is prone to deterioration in 4 hours under a closed environment.
4. Additional functions and brand reference
Plus point design
Removable tea leak, anti-slip bottom pad, one-button elastic cover, etc. to improve convenience.
Double-layer glass anti-scalding design or intelligent temperature control function is suitable for temperature-sensitive beverages.
Cost-performance ratio
Summary: Food-grade 304/316 stainless steel material is preferred, and capacity and design are matched according to the use scenario, and practicality is ensured through sealing and insulation testing.

1. Design concept: balance between capacity and aesthetics
Scientific capacity design
The capacity of mainstream products is concentrated between 1.5L-2.2L, meeting the minimum daily drinking water demand for adults (recommended for men and 2.7L/day for women), reducing the efficiency loss of frequent water withdrawal. The water bottle adopts a narrow mouth and wide bottom structure, taking into account portability and stability.
Health Management Tools
Scale marks help quantify the daily drinking progress and say goodbye to frequent water collection! Your all-weather watering artifact is here!

✅ Leak-proof design + portable lifting ring--inverted without spilling, easy to carry with one hand
✅ Minimalist Ins style--available in different colors, taking photos and checking in is super photogenic📸
2. Adapt to the scene
Large-capacity water bottles made of plastic are suitable for outdoors - essential camping, gyms and other scenarios. Common capacity includes 1L, 1200ml, 1600ml, etc., and are suitable for long-term outdoor exercise, fitness or daily hydration needs.
3. Design and customization
