Benefits
-
Health & Safety First – The 304 inner wall never rusts or leaches harmful chemicals. Optional 316 stainless steel offers even higher resistance to acidic beverages (e.g., juice, soda). FDA/EU/LFGB certification gives parents peace of mind.
-
All-Day Temperature Retention – No more lukewarm water by noon. Kids enjoy cold water after PE class or warm milk during winter mornings. The vacuum insulation also prevents external sweating – no wet hands or soaked schoolbags.
-
Versatile Drinking Experience – The dual-opening lid adapts to different ages and situations. Straw mode: ideal for toddlers and on-the-go drinking without tilting the bottle. Direct spout: faster flow for older kids or when they need a big sip.
-
Durable & Kid-Proof – The 201 outer wall resists dents and scratches. With a protective silicone bottom pad, the bottle survives drops from desk height. Customizable colors and prints make the bottle uniquely theirs, reducing the chance of loss or mix-ups.
-
Easy to Clean & Maintain – Wide mouth (approx. 5 cm diameter) allows hand washing or dishwasher placement (top rack recommended). The lid components are disassemblable for thorough cleaning.
-
Brand Building Ready – Custom surface finishes and high-resolution printing turn the bottle into a walking billboard for your brand. Choose from 20+ Pantone colors for the body and 8 colors for the silicone pad. MOQ=3000 makes it accessible for school promotions, kids’ meal campaigns, or retail launches.

FAQ (6 Common Questions)
1. Is the outer wall made of 201 stainless steel safe for children? Can I upgrade to 304 or 316 for the entire bottle?
Yes, the 201 stainless steel used on the outer wall is perfectly safe because it never contacts the beverage. It provides strength and dent resistance while keeping costs reasonable. The inner wall (contact layer) is always food-grade 304 stainless steel. However, if you prefer a premium all-304 or all-316 Kids Bottle, we offer a full-material upgrade. Please note that all-316 increases unit cost by approximately 18-22% but provides superior corrosion resistance – ideal for acidic fruit juices or carbonated drinks. Just specify your requirement in the inquiry.
2. What certifications do you provide? Do you support testing for our local market?
Standard certifications for this Kids Bottle are FDA (US), EU (EU10/2011), and LFGB (Germany). We provide test reports from accredited labs (e.g., SGS, TÜV, Intertek) showing compliance for:
-
Overall migration (food contact)
-
Heavy metals (lead, cadmium, nickel release)
-
BPA, BPS, phthalates
-
Thermal shock and vacuum retention
If you need additional certificates like CPSIA (US children’s products), California Prop 65, or Japanese Food Sanitation Law, we can arrange testing at cost. Typical lead time for extra certifications is 15-20 days and adds $300-$500 per test.
3. What is your MOQ? Can we start with a smaller trial order?
MOQ for fully customized Kids Bottle (custom printing, finish, packaging) is 3000 pieces. This is the minimum to cover mold amortization (if any new parts) and setup costs for silk screen or heat transfer. However, we understand market testing needs. For first-time partners, we offer two options:
-
Stock sample order: 500 pieces with your logo printed (using our standard colors and packaging). Lead time 25 days.
-
Pre-production batch: 1000 pieces with partial customization (e.g., only printing or only silicone pad color change). Additional mold fees may apply.
For quantities below 3000, unit price increases by 15-25%. Please contact our sales team for a tailored quote.
4. Does the double-wall vacuum insulation keep hot liquids safe for kids? What are the temperature limits?
Yes, the vacuum insulation reduces external heat transfer, so the outer wall stays warm but not burning hot (typically under 45°C/113°F when filled with 95°C/203°F liquid). We recommend filling with beverages below 60°C/140°F when giving to children under 6 years old to prevent accidental scalding from the spout. The insulation performance:
-
Hot retention: From 95°C to 40°C in 6-8 hours (room temperature 20°C).
-
Cold retention: From 4°C to 12°C in 10-12 hours.
Do not microwave, freeze, or carbonate in this bottle. Avoid dry ice or over-tightening the lid when filled with hot liquid (pressure buildup).
5. How do I clean the dual-opening lid? Does it leak?
The lid disassembles into three parts: outer cap, straw mechanism, and silicone gaskets. All parts are top-rack dishwasher safe (max 65°C). For hand washing, use a small brush to clean the straw channel. Our Kids Bottle passes a 2-hour inverted leak test with water at 45°C. To ensure no leakage:
-
Always close the pop-up straw completely (click sound).
-
Check that the silicone gasket on the screw cap is seated properly.
-
Avoid over-tightening – it can deform the gasket.
We include one spare gasket set per 50 bottles for bulk orders. Replacement straws are available as an accessory.
6. What is your warranty and after-sales policy for defective bottles?
We provide a 12-month manufacturing warranty from the shipment date. Coverage includes:
-
Vacuum failure (bottle no longer insulates – test by feeling external temperature after 1 hour of hot water).
-
Leaking due to defective lid or gasket.
-
Rust or pitting on inner wall (304 material).
-
Printing that peels under normal use (adhesion test failure).
