Abstract
Abstract A chamber pot for infant use comprising a body having a well in the base of its urine receiving chamber, the well being closed at its lower end by a diaphragm electrical contact unit. The diaphragm is flexed by the presence of urine in the well to close its contacts and energize an illuminable stimulus. The illuminable stimulus has an electric lamp housed within a hollow section of the chamber pot. An electric battery is housed between inner and outer side walls of the chamber pot the outer side wall providing the floor support for the chamber pot.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
196 words
A chamber pot for infant use comprising; a. a body having a base and inner side wall portions defining a urine receiving chamber, a downward extension from the base defining a well towards which said base slopes so that urine flows from the base into the well, and an outer side wall portion defining an annular space between it and the inner side wall portion and extending below said base and the lower end of the well to provide by its lower edge a floor standing support for the chamber pot, b. a diaphragm electrical contact unit closing the lower end of the well and having a pair of contacts which close upon downward flexing of the diaphragm caused by urine in the well, c. a battery housing contained within the annular space, d. an illuminablE stimulus comprising an electric lamp mounted on the chamber pot so that when illuminated it is visible to an infant seated on the chamber pot, and e. an electric circuit extending within the annular space between the battery housing, the diaphragm electrical contact unit and the stimulus so that closure of said pair of contacts causes illumination of said stimulus.
Claim 2
Dependent Claim
