We believe that such small items as lids or straws should not be neglected in designing process . And at the other end of the scale they should not lessen the user convenience .
Bottle's lids are consisted of two parts : the lid and a circular ring below it which can rotate like the lid itself . The difference is that the lid rotates in a upward manner but the ring stays at the same location.By attaching these two with the same plastic used in the ring(highlighted in red) we can assure they work together .However , it will annoy the user by disturbing him when he is trying to drink from the bottle. By designing a way to attach the lid to the body we can abolish this disturbance . So we reached to the below method as the best and a cost effective way to do this.
We designed a fastening mechanism which attach the lid to the bottle in a way resembled in the pictures by dots and holes .
Some dots on the lid and the regarded holes on the body .
This mechanism can be improved with no cost to be modified as a braille word in order to help the blinds reach their products in supermarket's shelves.The braille word is the indication of the contains of the bottle.
For instance , in our model the word "W" in braille language was demonstrated as for water .
