Spiral Makes a Difference

Think about it, instead of having a straight tube ink refill, how about fashioning it as a spiral? Agreed it occupies a bit more space so the pen can’t be sleek and slim, but it holds double the amount of ink! There’s a reason why our DNA is structured in a double helix. I guess it will work like a charm for those disposable types, making them last longer. I won’t call this project 100% eco-esque but it’s a step towards it!

    I agree with what Mike Barnard said about just making the ink barrel fatter. However, my first instinct was to say, why not just make the spirals touch each other and get as much as five times the amount?

    do you use a pen for a month?????????
    how can it be? for me, it’s 4 pens for a month!
    one for every week, because we have to write lots of things in our schools,
    so this invention is really cool!!!!!!!!!!

    …or you could make just a thicker tube like other pen manufacturers 😉

    as far as i know there is a specific size of the tube that have the appropriate amount of surface tension so that it doesn’t spill over or catching air inside the tube.
