  • Mass based low product indicator
    Patent number: 9764937
    Abstract: A dispenser dispenses a consumable product from a container. The container is supported within a housing by a container holder. The container holder is vertically moveable within a movement range in the housing. A biasing structure biases the container holder upwardly. A sign is connected to move up and down with the container holder. An indicator associated with the sign is vertically fixed relative to the housing. When an amount of product remaining in the container reaches a low level, the biasing force of the biasing structure will lift the container holder, causing the indicator to be aligned with a portion of the sign that gives a visual cue to a user that the amount of product remaining is at a low level.
