Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
149 words
A reusable image generating toilet training device for children comprising: a) a receptacle for receiving urine from a child; b) a chair member having an opening therein for receiving and supporting said receptacle; c) said receptacle having a bottom, sides and an open top; d) a reversible image generating element having a first latent image phase operable at a first predetermined temperature and a second exposed image phase operable at a second predetermined temperature such that re-exposure to the first predetermined temperature will result in a change back to said first latent image phase; and e) said image generating element is positioned on said receptacle bottom and viewable by the child from said open top so that when the child urinates into the receptacle, the urine will collect on the receptacle bottom and cover the reversible image element generating said second exposed image phase for viewing by the child.
Claim 2
Dependent Claim
