A roll holder of the type for mounting split-core rolls of tissue is positioned in a dispenser moveable from an upper dispensing position to a lower exhausted position. A latch retains the roll holder in the dispensing position until tissue exhaustion permits relative movement between the split-core parts with consequent roll holder part movement to release the latch for movement of the roll holder to the lower exhausted position. The improvement includes blocking members at roll holder opposite ends normally retained inactive permitting the foregoing latch release by presence of the split-core parts, but automatically moving to active preventing latch release upon a lack of core retention. This means that the split-core must remain for proper roll holder functioning, and also that a solid core roll cannot be used with core stripping to cause roll holder functioning, in either case avoiding core stripping from the roll holder which can result in littering.
