The Perfect Peanut Butter Jar Works Like A Push-Pop

The team began prototyping through the school’s 3-D printers. And what they developed was a jar that twists on the bottom, slowly screwing its way up, pushing the peanut sediment toward the container’s surface (just like deodorant). As for its ecological impact, Smith describes the container as “a normal peanut butter jar plus one more lid,” with a materials cost that would increase packaging from an average of $0.10 to $0.13. But the team believes that the convenience factor can equate to a 30-40 cent increase on the store shelf, and there is something to be said for every consumer being able to eat 100% of the peanut butter rather than throwing scrapings away.
