Definitions

  • the present disclosure relates to dispensers, and particularly to dispensers configured to dispense interfolded sheets of media, such as napkins, towels, and wipes.
  • Dispensers for dispensing interfolded sheets are known. Some prior art dispensers are configured such that a pack of interfolded sheets can be installed through the same opening through which the sheets are dispensed through the use of various types of swinging or hinged doors, such as bomb bay-style doors. With such configurations, the height of the dispenser can be at least partially defined by the degree to which the doors extend into the interior space of the dispenser in order to allow the pack of interfolded sheets to move fully past the doors such that the doors can return to their normal position. Other designs require a separate access opening at either the bottom or sidewall of the dispenser. To facilitate these types of operations, a number of moving and non-moving parts can be required within the dispenser.
  • this disclosure is directed to dispensers, and in particular dispensers configured to dispense discrete sheets of media from a pack of interfolded sheets of media.
  • the sheets can be any type of media, for example, paper towels, wipes, or napkins.

For example, paper can be easily added to the dispenser without first requiring the opening of the dispenser to access the interior. Another advantage is that the disclosed configuration reduces
  • the disclosed design also significantly reduces the number of required parts in comparison to prior art designs which have various types of hinged door structures. The disclosed dispenser is thus more easily cleanable.
  • Another advantage is that the configuration of the cover member 134 with the elastomeric extension members 134a - 134d results in a reduced required height or length of the dispenser (i.e. distance between the base 112 and the cover member 134). This reduction is accomplished because the extension members 134a - 134d are pliable to such a degree that they do not have a fixed hinge point , thereby allowing the extension members 134a - 134d to curve or bend out of the way to only the extend necessary for the pack to move past the opening 130a. This same flexibility feature also allows for less required head space 11 above the media pack 10.
