We found another problem in the market that needed to be solved.
In the traditional pet waste station, as the roll of bags gets smaller, there is a tendency for the roll to move to the back of the dispenser shelf. This can make the bags very difficult to reach, particularly if you have short fingers.
Our first thought was to slant the shelves forward, but testing showed that this caused the rolls to fall out during refilling. This led to a new idea: why not mount the shelves on the front door of the pet waste station? This way, when the station is opened for filling, the rolls are cradled against the front door of the station. When the door is closed, the rolls of dog waste bags slide to the front.
As the bags are used, the roll moves toward the front. This design received the short finger seal of approval!
