Trans-cap / Trans-cap


When filling with water or flushing the PET bottle, often need to tilt the bottle to fill with water because of the bottle's height is unsuited with the drinking fountains or sink's height.

Not to change the appearance as the starting point for this design, and design an independent gadget, don't have to change all PET bottles manufacturing method, to save more resources.

This gadget is a telescopic tube, one side with cap threaded to connect with PET bottles, middle part as telescopic hose, such like the bending part of bendable straw, can freely adjust the length and angle, and the back-end as the part to receiving water.
