A system used to rotatably support a roll of absorbent material within a dispenser. The system includes a plug pre-packaged only in one end of a core of a roll of absorbent material to be dispensed from the dispenser. The other end of the core is insertable into a boss extending from a wall of the dispenser. The plug mates with a hub member having a complimentary shape to that of the plug. The hub member is rotatably supported within an arm connected to a wall of the dispenser.
1. A dispenser for dispensing sheets of material from a roll of absorbent material, comprising:
a dispenser housing;
a roll of absorbent material wound around a core and rotatably mounted within said dispenser housing;
a plug insertable at least part way into at least one end of said core, said plug having a first shaped portion at one end face thereof;
a hub member having a complimentary shape that interlocks with said first shaped portion; and
a support arm extending from a rear wall of said dispenser housing, said hub member being rotatable within said support arm.
2. The dispenser as claimed in claim 1 , further comprising an alignment member coaxial with said hub member.
3. The dispenser as claimed in claim 2 , wherein the alignment member is annular.
4. The dispenser as claimed in claim 2 , wherein the first shaped member is a non-circular opening.
5. The dispenser as claimed in claim 4 , wherein said plug includes a flange that prevents said plug from being pushed completely inside said core.
6. The dispenser as claimed in claim 4 , wherein the non-circular opening is substantially Z-shaped and is coplanar with said flange.
7. The dispenser as claimed in claim 4 , wherein the non-circular opening is an elongate slot with a circular central portion having a diameter wider than said slot.
8. The dispenser as claimed in claim 2 , wherein said hub member comprises arms that extend through said support arm and releasably engage said alignment member.
9. The dispenser as claimed in claim 1 , wherein the first shaped member is an opening and said hub member is a male member.
10. The dispenser as claimed in claim 9 , wherein said opening is non-circular.
