Definitions

  • the present invention relates in general to the field of lavatory accessories. More particularly, the present invention relates to a product dispenser, e.g., a paper hand towel dispenser. Specifically, a preferred embodiment of the present invention relates to a paper towel dispenser include an insert that reduces the volume of the paper towel dispenser adjacent its opening in order to slightly bow the stack of product at the opening and aid in extraction of the product form the dispenser with reduced tearing.
  • Product dispenser e.g., paper towel dispensers, commonly used with commercial lavatory systems generally include a container for holding a supply of either stacked paper towels or rolled paper towel.
  • the interior of the container is generally rectangular in shape and the stacked paper hand towels are merely shoved by a maintenance person into the space.
  • maintenance personnel tend to overfill the dispenser by placing as many paper towels within the container as possible.
  • the paper towels end up exerting a large amount of force on themselves and the lowest towel at the discharge opening is likely to tear due to this large pressure force.
  • the generally rectangular shape of the interior of the container results in the force being placed equally along the entire length of the paper towel, which also makes it likely to tear.
  • a paper towel dispenser that alleviates the tearing issue by providing an interior orientation of the container that alleviates pressure from the center of the paper towel and allows for a user to easily grab and remove the paper towel without tearing. Further, it would be desirable to provide a paper towel dispenser with an indication system that easily indicates to maintenance personnel that the level of paper towels within the container and/or whether the container needs to be refilled. Additionally, there is a need in the art for a locking mechanism for a dispenser that allows a uniform key to be used across dispenser.
  • the present invention is directed to a paper towel dispenser including an insert that reduces the volume of the paper towel dispenser adjacent its opening in order to slightly bow the stack of product at the opening and aid in extraction of the product from the dispenser with reduced tearing.
