the simple act of twisting the cap of a bottle can be a difficult task. as you place your fingertips around its edge and feel each of the individual ridges embedded into its plastic surface, you twist and try to break the seal, hoping that the liquids won’t burst out from the top. if it doesn’t open, you annoying repeat the action with more force and aggression until your skin ends up being irritated and you have to ask a friend for help. upon analyzing this design flaw, dijangin has designed a product called ‘sodavalve’ to ease the process of opening and closing a bottle.

the device is available in two models that appear as miniature representations of forms seen throughout time: a steering wheel and a kitchen sink handle. these are geometries that have been replicated and reproduced because they work with an understanding of the human hand, enhancing any grip applied to them. in addition, the designers have realized that they provide another layer of functionality. based on the observation that carbonation constantly leaks through the rim of a bottle in small increments, the wide ring structure of the ‘sodavalve’ can establish a based when turned upside down to fully seal its contents and thus, prevent the beverage from turning into flat sugar water.
