crustless sandwichAre you a fan of peanut butter and jelly? The inventors of the "sealed crustless sandwich" likely had you in mind when they came up with their idea--a method for creating a round, prepackaged sandwich that contains two types of filling, such as peanut butter and jelly.
This diagram illustrates a cutting cylinder that can be used to create such a sandwich, which can then be stored for "extended periods of time for use in lunch box type of situations." The idea is protected by U.S. Patent No. 6,004,596.
This branch-shaped toy is intended to amuse a dog or other pet. It can be made of rubber, plastic or wood, and a scent can be added. It's protected by U.S. Patent No. 6,360,693.
