  • Patent number: 11230414
    Abstract: A lid designed to allow a user to see and adjust the humidity levels of a container using a hygrometer and pocket for humidity packs. The lid also allows this to be accomplished without removing the lid because a hatch gives the user access to the inside of the container and underside of the lid, where the pocket is located. Also, the hatch on the lid provides a more efficient and easier method of accessing the contents of a container because a user can simply open and close a hatch, instead of needing to unlock a lever locking latch to remove a lid.
