CBC Alternate Design #1

This is the same concept as Voyager, with a different exterior design: I started with a basic insulated design to keep drinks cold or hot. The lid has a gasket to make it water-tight. A quarter-turn will open/close the mouthpiece with nubs on either side to lock it into position. In the open position, a hole will form through the lid assembly to allow air to escape while water pours through the mouthpiece. It could either be machined from the 18/8 or over-molded rubber for a better grip. The lid components will be injection molded, using a softer material for the twisting mechanism. Capacity is ~23-24 oz. Hope you like it!
