This design is the concept of filtering water cup for outdoor and travel scenes. Party A's requirements are clear. The spring cover structure, locking device, built-in knob-type suction nozzle and filter element reserved warehouse are the core requirements. At the same time, the product hopes to have both interesting and novel experience.
Based on the above demands, we introduced the concept of filter cup with TPU flexible cup body and nylon rope. Nylon rope, as the core expansion component, has multiple usage modes: the rope can be worn from the top cover to the front button to act as a lock catch, and can also be used as a handle lanyard; After the cup body is folded and stored, it can be fastened and fixed with ropes, and the cup can be tied to other equipment to expand various outdoor usage scenarios.
On the premise of implementing the basic functions, the suction nozzle is redesigned following the lip shape: when screwing, the suction nozzle is vertical, representing undrinkable; After unscrewing, the suction nozzle is horizontal and enters a drinkable state. The new shape can intuitively distinguish the opening and closing state, optimize the lip fitting feeling at the same time, and improve the drinking comfort.
