  • Dispenser package for magnetic tape splicing tabs
    Patent number: 4113141
    Abstract: A device, and method for assembling same, is disclosed for the itemized dispensing of tabs having an adhesive coating on one side thereof, which tabs are polygonally shaped and obliquely, releasably mounted on a rolled strip of backing material. The device comprises a roll of such tabs disposed within a box having one side thereof with a triangularly shaped opening in its lower end. The triangular opening is defined by the box edge adjacent the opening and the lower side edge, which intersects the box edge at the angle of obliquity at which the tabs are disposed on the backing strip. As the backing strip is drawn through the opening, the leading edge of a tab will be exposed free and clear of the box edge, and the entire tab will be exposed free and clear of the lower side edge, whereby the tab may be peeled from the backing strip. As the leading edge of a tab is exposed free and clear of the lower box edge, one, and only one, entire tab is exposed exterior of the box.
