  • Patent number: 4796781
    Abstract: A desk type dispenser for dispensing note sheets which are adhered together along opposite alternate edges by a narrow band of adhesive coated on one surface of the sheets comprises a base member and a body member. The body is preferably weighted and sits on the uppermost sheets in the stack and is provided with a dispensing opening therein which communicates with arcuate wall members communicating with the bottom surface thereof. Recesses in one of the body and base and projections in the other member cooperate to afford a nesting of the base and the body. A platform on one of the members and a recess on the other affords a positioning of the stack of sheets with respect to the two members and stability for the stack of sheets.
