Abstract
A system for refilling a stick product, such as lipstick or deodorant, in a propel-repel dispenser allows the reuse of the propel-repel mechanism. The stick product refill is shaped and dimensioned to be inserted into the open end of the dispenser and to attach to the receptacle that holds the stick product after the used product has been removed. Attachment of the refill to the stick receptacle is by an attachment component on the outer surface of an anchor cap enclosing the distal end of the refill and/or on the receptacle itself. Once secured to the receptacle, the refill can be advanced and retracted by the propel-repel mechanism so that it protrudes when in use and is withdrawn with the dispenser to protect it when not in use.
