Abstract
Notepaper dispensers formed from inexpensive card stock material tend to weaken and tear when subjected to concentrated forces, and the dispenser of the present patent is provided with lengths of polymeric material adjacent the edges of the dispensing opening which will bend and flex more reliably, and a biasing member is disposed in the container for biasing the notepaper toward the dispensing opening.
Claims11
A dispenser package for sheet material wherein the sheet material is disposed in a stack and the sheets are releasably adhered to each other in the stack along opposite edges of successive sheets by a narrow band of pressure-sensitive adhesive, said package comprising
- a stack of said sheet material,
- a card stock box having a bottom, side walls and a top wall, said top wall having an opening extending generally centrally thereof and defined by opposed parallel edges extending the width of the top wall, a pair of flaps, each flap being formed of polymeric material and said flaps being disposed for one to extend from each interior surface of said top wall on each side of said opening and into the opening beyond each of the opposed edges of the opening, said flaps terminating at terminal edges in opposed spaced relation and each flap having free side edges movable in relationship to the side walls of the box, said flaps being positioned to normally rest on the top of said stack and said polymeric material forming said flaps having the flexibility to form an arcuate bend transversely of the flap between the edge of the opening and the terminal edge of the flap during dispensing of sheets from said stack and having the resiliency to recover the rest on the top of the stack, and
- biasing means disposed beneath said stack of sheet material for urging the stack of sheet material toward the opening whereby dispensing of a sheet from said stack draws said sheet around said arcuate bend in the flap and draws the successive sheet through a wider opening to restrict the forming of a curl in either sheet.
A dispenser package according to claim 6 wherein the spring is formed of convolutely wound wire to form a compression spring.
