Claims14
A coin holder comprising a hollow cylindrical tube that includes two semi-cylindrical wall sections hingedly connected together for fold-up into a flat package;
- and a circular end wall for said tube;
- said circular end wall comprising two semi-circular sections hingedly connected to respective ones of the tube sections for movement between a folded position extending within the flat package and an unfolded position extending normal to the tube axis.
A coin holder comprising a hollow cylindrical tube formed of a single sheet of stiff paper that has its axial end edges overlapped and adhesively secured together;
- two longitudinal creases extending the length of said stiff paper sheet to define two semi-cylindrical wall sections hingedly connected together for fold-up into a flat package;
- and a circular end wall for one end of said tube;
- said circular end wall comprising a second sheet of material separate from said tube-forming sheet;
- said second sheet having a crease therein subdividing the circular wall into two semi-circular sections that can fold or unfold around the associated crease;
- said second sheet comprising two tabs extending from the circular wall on an imaginary line normal to the associated creases in the second sheet;
- said tabs being adhesively secured to outer face areas of the tube sheet so as to hingedly connect the semi-circular sections of the end wall to the tube.
