  • Patent number: 5374008
    Abstract: An spindle (10) for use in a dispenser (12) for rolled material such as toilet paper includes a core (30) having a length to extend between the inside surfaces (22, 24) of the dispenser (12). The first end (32) of the core (30) is held in the dispenser recess (26) by a plug (34) threadably received therein. The second end (38) of the core (30) is held in the dispenser recess (28) by a sleeve (40) telescopically received therein and which is biased outwardly by a compression spring (56). Access to the sleeve (40) is provided only at a location intermediate the ends (32, 38) and which is overlain by the rolled material while access to the sleeve (40) is effectively prevented adjacent the second end (38) of the core (30) and the dispenser recess (28). In the most preferred form, a longitudinal slot (54) is formed in the core (30) to allow access to the sleeve (40) and specifically to a tab (48) formed on the sleeve (40) having a detent (50) which extends into the slot (54).
