Any medical pill has its time of expiration, but it is difficult for an elder or a visually impaired person to remember or recognize, and take the pills after its expiration. The design uses the PLA environmentally friendly corn plastic to make the bottle; it will generate bumps on the surface with the passage of the time after you open the seal, so the user can notice that the pills are out of the date when the bottle is inflated.
