Yeah I thought the same .... I keep buying the same peanut butter brand with the same clear hardened plastic container all the time. After a few years, my entire garage shop is now filled with clear plastic containers with lids that I use for anything and everything. They come in great for holding nails and screws and small parts but also for managing all kinds of liquids and oils.

If they did the same for all containers, people would be using all this stuff over and over again before trashing them.
