Some interesting industrial design from Sherwood Forlee. His Easy PB&J Jar features a clean and simple glass jar with two lids.
The Easy PB&J Jar is a jar with two lids that allows you to access all of your peanut butter easily without having to resort to breaking open the jar. As you near the end on one side, simply flip the jar over to get the rest. The straight and smooth internal walls also ensure that no peanut butter is ever left behind a nook or cranny like existing jars.
