A dispenser for a roll of strip comprising an open top casing. A cover is pivotally mounted on the casing for closing the top thereof. Disposed within the casing is a roll of strip having transverse slits formed therein at predetermined distances along the strip. The free end of the strip to be removed from the roll of strip exits from an opening located between the casing and the cover. Extending from the casing are transversely spaced tracks that project outwardly and downwardly from the casing, and over which advances the free end of the roll of strip. Extending from the cover are outwardly and downwardly transversely spaced guides, which overlie, respectively, the transverse tracks to form passages therebetween. The free end of the strip travels through these passages. The tracks and guides are correspondingly curved to bow the free end of the roll of strip at the transverse slit advancing through the passages to open the slit. A spring mounted on the casing applies a force to retard the egress of the strip of the roll of the tape. An operator grips the free end of the roll of strip disposed between the transversely spaced tracks and guides and applies a downward force to the free end of the roll of strip. The free end of the roll of strip is torn from the roll of strip at the transverse slit exiting from the passages by virtue of the force applied to retard the egress of the roll of strip of the roll of strip, the force applied to the free end of the roll of strip by the operator, and the frangibility of the free end of the roll of strip at the opened slit.
