CONTAINER TUMBLER / Tumbler

A common tumbler's function is to be able to carry around a large amount of liquid easily, but there is a problem. After drinking all the contents inside, the user rarely refills it with other beverages because of the cumbersomeness of it all. CONTAINER TUMBLER concept is to use the other side of the tumbler lid area and provide it as a small space to store various water mixing powders or other contents. This way, the user is able to continuously refill the tumbler with the type of drink he/she prefers. Users can also store other things like medicine pills for easy access.
