AI Technical Summary
Technical Problem
Traditional in-the-bowl (ITB) devices dispense compositions simultaneously with the flush, preventing germicidal agents from remaining in contact with the toilet bowl long enough to provide effective germ-killing benefits.
Method used
An ITB system with an immediate and delayed release chamber, utilizing a siphon mechanism to dispense compositions at staggered time intervals, ensuring the germicidal agent remains in the toilet bowl after flushing to achieve optimal germ kill.
Benefits of technology
The system maintains an effective concentration of germicidal agent in the toilet bowl, providing prolonged germ-killing benefits with every flush operation.

Abstract
The present invention is directed to an in-the-bowl (ITB) system for dispensing at least two compositions into a toilet bowl at staggered time intervals comprising an ITB device arranged in the toilet bowl. The ITB device further includes an immediate release chamber having an inlet on a top surface and an outlet on a bottom surface and containing a first composition therein, a delayed release chamber having an inlet on a top surface, and a mechanism defines a triggering threshold and a terminating threshold, wherein the triggering threshold starts a flow out of the delayed release chamber at a staggered time interval, and the terminating threshold stops the flow out of the delayed release chamber allowing a predetermined amount of flush water to remain in the chamber creating a reservoir of a predetermined volume in the delayed release chamber.
