Abstract
A pressure sensitive adhesive tape, such as a white typing correction tape, is wound up with backing tape or a liner tape wound between successive turns of the tape. The backing tape is cut into short lengths, and the correction tape is bent sharply back upon itself over a "peeling" member as it is dispensed, to separate the short lengths of the backing or liner tape and leave them behind in the carton. The space within the standard size dispenser package is adequate to hold the waste pieces of backing tape as the correction tape roll is used up. A short cutting blade may be provided to cut off desired lengths of the correction tape.

A dispenser package assembly of pressure sensitive adhesive tape wound with a liner or backing strip comprising:
- a roll of pressure sensitive adhesive tape including a liner or backing strip wound up with said tape, said liner or backing strip being cut into a series of short lengths while still attached to the pressure sensitive adhesive tape;
- a dispenser package containing said roll;
- said dispenser package including an exit opening for said pressure sensitive adhesive tape;
- and
- said dispenser package further including peeling means adjacent said exit opening for sharply bending said pressure sensitive tape back on itself to separate said pressure sensitive adhesive tape from said short lengths of liner or backing strip within the package;
- whereby, as said pressure sensitive tape is used up, the waste short lengths of backing strip or liner are held within the package and occupy some of the space previously occupied by the original roll of tape.
A pressure sensitive tape dispenser assembly comprising:
- a roll of pressure sensitive adhesive tape including a liner or backing strip wound up with said tape, said liner or backing strip being cut into a series of short lengths while still attached to the pressure sensitive adhesive tape;
- a dispenser containing said roll;
- said dispenser including an exit opening for said pressure sensitive adhesive tape;
- and
- said dispenser further including peeling means adjacent said exit opening for sharply bending said pressure sensitive tape back on itself to separate said pressure sensitive adhesive tape from said short lengths of liner or backing strip within the dispenser;
- whereby, as said pressure sensitive tape is used up, the waste short lengths of backing strip or liner are held within the dispenser.
A dispenser package assembly of pressure sensitive adhesive tape wound with a liner or backing strip comprising:
- a roll of pressure sensitive adhesive tape including a liner or backing strip wound up with said tape, said liner or backing strip being cut into a series of short lengths while still attached to the pressure sensitive adhesive tape;
- a cardboard carton type dispenser package containing said roll;
- said dispenser package including an exit opening for said pressure sensitive adhesive tape;
- said dispenser package further including peeling means adjacent said exit opening for sharply bending said pressure sensitive tape back on itself to separate said pressure sensitive adhesive tape from said short lengths of backing tape within the package;
- said peeling means including means for constraining said pressure sensitive adhesive tape with said liner or backing strip to follow a path along the inside of one narrow side of said package which is substantially parallel to the axis of the roll of tape, and said peeling means further includes means for directing the pressure-sensitive tape, free of the pieces of liner or backing strip back along the outside of the same section of the same narrow side of said package;
- and
- said peeling means being implemented by tabs from said package folded along one side of said package;
- whereby, as said pressure sensitive tape is used up, the waste short lengths of backing strip or liner are held within the package and occupy some of the space previously occupied by the original roll of tape.
