A pro-hockey player and inventor from Alberta thinks he's solved a problem that has plagued kids forever: how to get the last bit of peanut butter out of the bottom of the jar without getting it all over your fingers. The Toronto Star reports that Darren Kramer has applied for a patent on an improved peanut butter jar. The jar's top half twists off to allow easier access to peanut butter in the bottom.Kramer isn't the first inventor to tackle this problem. In 2009, Ryan Coffey of Wisconsin filed an application (US2009261098 A1) for a jar (that closely resembles the peanut butter kind) with lids at both ends, presumably to allow for easier access to the peanut butter at the bottom.
I'm the librarian for research services in the Engineering and Science Library at Queen's University in Kingston, Ontario. I've been working with patent information since 1991, including seven years at the U.S. Patent and Trademark Office. I believe that the dissemination of patent information is a public good and should be promoted, especially in the education of science and engineering students.
