This is patent for a spherical deodorant container (to use in the car, house, etc...)... the idea consisted of a container that would gradually change color simultaneously with the loss of the deodorizing effect of the deodorant in the container... one can do countless things with plastic materials... not just toys... --Asagoth (talk) 23:24, 26 February 2020 (EST)
