One-Touch Flip Lid Design
Built for the sports and outdoor market, this thermos addresses the pain points of inconvenient drinking and easy slipping during exercise and outdoor running. The lid uses a press-to-flip mechanism that opens instantly with a single push. Users can drink with one hand during exercise without unscrewing a lid, matching the usage patterns of gym workouts, running and ball sports. Select models include a temperature display function that shows internal water temperature at a glance, preventing scalding after intense activity.

Anti-Slip Grip & Drop Resistance

Textured anti-slip patterning covers the outer body for a secure hold even when hands are sweaty from exercise. The thickened stainless steel structure offers strong impact and compression resistance, so the thermos resists deformation if dropped during sports or outdoor use. It holds between 401ml and 500ml, sized appropriately for on-the-go hydration during workouts and outdoor activities.
Ergonomic Body Contour
The body curve is shaped to follow the natural grip of the hand, reducing fatigue during extended holding during long outdoor sessions. The interior carries a MARSCOAT easy-clean coating that simplifies removal of drink residue, sports drink buildup and electrolytes after use. The 201 stainless steel outer shell adds structural durability at an accessible price point.
Customization & Production QC
Dongke Electric Heating offers full OEM and ODM customization, including custom body colors, printed brand logos and sports slogans, and adjustable lid configurations. Every unit receives full in-line inspection of flip lid rebound performance, sealing integrity and vacuum level, with AQL sampling on finished batches. Export cartons include internal cushioning for transport durability.
