A refillable tape dispenser including opposed hub portions adapted to project axially into and journal the core of a roll of tape. Each of the hub portions includes cam surfaces having ends ending at an inner surface, which cam surfaces are disposed generally parallel to a first direction in which tape is withdrawn from the dispenser and diverge away from opposite sides of the inner surface. Movement of the tape roll toward the inner surfaces of the opposed hub portions in a direction normal to the first direction will cause the tape roll to engage the cam surfaces and move one hub portion to a release position until the hub portions are aligned with and enter the central opening in the core under the influence of biasing toward that position, whereupon end surfaces of plate like parts of the hub portions will retain and journal the core around the hub portions during withdrawal of tape in the first direction. Upon subsequent movement of the empty core in a direction normal to the first direction the core will also engage the cam surfaces and move the one hub portion to the release position so that the core can be removed from the dispenser.
