Abstract

A hand held dispenser for liner wound adhesive tape having walls that define a first cavity for storing a supply roll of liner wound tape, a second cavity with an inner wall surface which causes liner pushed into the second cavity to wind into a coil, an opening through which liner may be withdrawn from the dispenser, and a other means for connecting the first cavity and the opening adapted to guide the tape being withdrawn through the opening, and for connecting the cavities to guide the liner from the first cavity into the second cavity, and for separating the liner from the tape being withdrawn so that tape being withdrawn will propel the liner along the path means and into a coil in the second cavity.

Claims

1. A hand-held dispenser by which lengths of pressure-sensitive adhesive coated tape may be withdrawn from a supply roll of said tape convolutely wound with a release liner between its coils, said dispenser comprising walls defining:

a first cavity adapted for storing said supply roll;

a second cavity adapted for storing said liner, said second cavity being partially defined by an inner wall surface adapted to direct liner pushed into said second cavity to wind into a coil;

a tape outlet opening; and

path means for connecting said first cavity and said outlet opening adapted to guide tape being withdrawn from said dispenser through said opening, for connecting said cavities to guide said liner from said first cavity into said second cavity, and for separating said liner from tape being withdrawn from said opening so that tape being withdrawn from said opening will propel said liner along said path means and into a coil in said second cavity.

2. A dispenser according to claim 1 wherein said cavities are generally cylindrical.
