Since the Free Library of Philadelphia is a Patent & Trademark Resource Center, we are able to appreciate some of the very interesting patents granted by the U.S. Patent & Trademark Office and by foreign patent offices around the world. Featured here are some unusual patents that are geared toward the mail…
This foreign patent is a very efficient invention for cat lovers. The lower box on the Mailbox with Stray Cat Nest is a mailbox and the upper box is a stray cat shelter. The efficiency aspect kicks in when “people can feed the cats by the way when fetching the mail[s].” Makes a trip to the mailbox a whole lot more fun! (Top image)
If you like the idea of keeping old rubber tires out of landfills, check out the Rubber Tire Mailbox, a patented device using an unwanted tire to make a mailbox. (Middle image)
