Sesame cookware, a patented invention

Are you an entrepreneur or a producer of cookware who's looking for something new? Could this be a cooperation opportunity?


The invention

Sesame Cookware is something totally new, it's a cookware which will watch your back while you are preparing the next dinner. Once the temperature rises and the water starts boiling the glass part of the lid opens. If you then reduce the power the lid closes, still keeping the water boiling! This is a perfect over boiling guard and it's still a normal lid. Using the patented Sesame Lid makes it possible for you to use a lid when you would normally take the lid off - due to the risk of over boiling. This will reduce the waste of energy.

How does it work? A wax thermostat is used, the same kind as is used in every car. Once the wax starts to melt it expands and forces a piston to move and this movement will act on a mechanism that opens the glass lid. It's very simple, controls the boiling very well and is very robust.

New business opportunity?

The lid could be advertised as a unique selling proposition and is energy saving since lid can be used more when food is prepared. This makes it possible for a cookware brand, producer or entrepreneur to be able to offer something special. Cookwares are all advertised as a quality cookware with a great design and in some cases a low price. For other products features are of great importance, this is not the case for cookware, simply for the reason, there are almost no features.

Having a lid that opens and closes, controlling the boiling is a feature that would make the brand stand out.

There is a Swedish patent. Is it expensive? A wax element used in milions of cars can be used in this application, for high volume production a wax element would cost just above 1€ per part. I got a quote on less then 2€ and this was on a volume of only 500 pieces.

How could it look?

Cookware with lid on a stove. With high power the lid opens and when the power is reduced the lid closes. If too much power is used the lid simply compensates for that by a greater opening. For example: Boiling pasta with a lid is now possible, and leaving boiling rice will not result in cleaning activites. Don't be limited to the designs I have come up with. This serves as design exemples only.




How does it work?

Video showing how my home made mechanism works. Important to have in mind is that the design is very depending on what I have been able to do on my own in my garage. The tools and resources have been limited, for a production solution it would have been made differently.

Swedish patent



The wax in the thermostats is something which thermostat producers do not specify, it's their know-how but I’ve got confirmation that it can be used in this application. There are no harmful ingredients which could be a stopper.
