A device for dispensing two compositions into a toilet bowl at different time intervals, the device comprising: a first container containing a first composition ; a second container containing a second composition ; a supporting cage supporting the first and second containers, a lever arm pivotably connected to the supporting cage by a pivot point ; the lever arm comprising a receptacle for temporarily retaining a portion of the flow of water during a toilet flush; a suspension means [H] for suspending the supporting cage from a portion of the toilet bowl to position the supporting cage within the flow of water during a toilet flush such that at least a portion of the flow of water is directed into the receptacle during a toilet flush; characterized in that : the supporting cage has a means for conveying the first composition to a first dosing cup or first collar and the second composition to a second dosing cup or second collar , wherein the first and second dosing cups/collars are disposed on the lever arm on opposite sides of the pivot point ; and the device further comprising a biasing means in contact with the lever arm ; wherein at the start of or during the toilet flush, the water retained in the receptacle causes the lever arm to rotate from its initial position about the pivot point and cause the first composition to be dispensed from the first dosing cup /first collar into the toilet bowl; and near or at the end of the toilet flush, the lever arm is biased about the pivot point by the biasing means to its initial position and causes the second composition to be dispensed from the second dosing cup /second collar into the toilet bowl. a first container containing a first composition ; a second container containing a second composition ; a supporting cage supporting the first and second containers, a lever arm pivotably connected to the supporting cage by a pivot point ; the lever arm comprising a receptacle for temporarily retaining a portion of the flow of water during a toilet flush; a suspension means [H] for suspending the supporting cage from a portion of the toilet bowl to position the supporting cage within the flow of water during a toilet flush such that at least a portion of the flow of water is directed into the receptacle during a toilet flush; characterized in that : the supporting cage has a means for conveying the first composition to a first dosing cup or first collar and the second composition to a second dosing cup or second collar , wherein the first and second dosing cups/collars are disposed on the lever arm on opposite sides of the pivot point ; and the device further comprising a biasing means in contact with the lever arm ; the supporting cage has a means for conveying the first composition to a first dosing cup or first collar and the second composition to a second dosing cup or second collar , wherein the first and second dosing cups/collars are disposed on the lever arm on opposite sides of the pivot point ; and the device further comprising a biasing means in contact with the lever arm ; wherein at the start of or during the toilet flush, the water retained in the receptacle causes the lever arm to rotate from its initial position about the pivot point and cause the first composition to be dispensed from the first dosing cup /first collar into the toilet bowl; and near or at the end of the toilet flush, the lever arm is biased about the pivot point by the biasing means to its initial position and causes the second composition to be dispensed from the second dosing cup /second collar into the toilet bowl. <EOS>
