The facilitation of the process of learning to drink was the focus of the development of the NUK Easy Learning Cup. Different from traditional cups, the modular NUK Easy Learning Cup no longer has a hard drinking spout but rather a raised circular section that interprets the formal derivation of a cup's edge. An innovative technology enables drinking while employing minimum suction power and provides a secure seal due to a valve in the cup's lid. The simple structure of the valve consisting of the base plate and a membrane cap made of silicone allows for easy disassembly and cleaning of individual parts.
