Biscuit Design


Improving the British biscuit for greater teatime enjoyment

I did an exploration on biscuit design initially inspired by the news that Nestle’s attempt to patent the KitKat was rejected by European courts, with an intriguing remark that a trademark cannot consist exclusively of:

“a) the shape which results from the nature of the goods themselves; or
b) the shape of goods which is necessary to obtain a technical result.”

In the sense, that the iconic four-finger bar design “the grooves existed to create the fingers which enabled customers to easily break off & eat the chocolate & that this therefore amounted to obtaining a technical result.” As compared to say Toblerone, where there is the unique aesthetic triangular form which expands beyond purely the technical design of separating the pieces.

So I explored what could be changed in KitKat to allow it to move beyond a technical result, but still keep the spirit of the beloved chocolate bar.

First I focused on defining KitKit, I believe it is as much about the ritual of eating the chocolate bar as as the chocolate. First I sketched the steps, of opening the bar (it is certainly a pity that the KitKat no longer has the foil & paper packaging.), & breaking each finger off the bar & each finger itself which aligns cleverly with its marketing slogan “Have a break, have a KitKat”.

Then I sketched some ideas in the spheres of changing the shape of the bar itself, & redesigning the packaging.

The Digestive

Taking the idea further, I decied to try my hand at improving another national icon, the chocolate digestive.
One main issue is that when holding a chocolate digestive you get chocolate on your fingertips, so I played around with some ways to avoid that.

I made a maquette of the easy-dip digestive after the exploratory sketches.

I’m continuing to explore biscuit design, & will keep this page update with any new developments.
