Abstract

A tape dispenser for use with a conventional tape roll, the tape dispenser has a finger grip piece insertable within the core of tape roll and a cover piece pivotally engageable with the holding piece for adjustably encompassing part of the periphery of the tape roll, the cover piece is contoured to be gripped with the holding piece to position the cover piece against the periphery of the tape roll for dispensing tape pulled from the roll at a controlled tension, and, the cover piece includes a projecting dispensing end with a tape guide and cutting edge for guiding and severing tape pulled from the tape roll.

Claims

1. A tape dispenser for dispensing tape from a conventional tape roll having an annular core, said tape dispenser comprising:

a finger grip piece having a crescent configuration insertable within the core of the tape roll, said finger grip piece having a first peripheral portion conforming with a portion of the annular core, and a second peripheral portion adapted for finger contact;

a cover piece having a top section with an underside contoured in part to the outer periphery of a tape roll and having opposite side sections covering in part the sides of a tape roll, said top section and side sections forming a tapered extension at one end of said cover piece wherein said underside of said top section in said extension projects a distance substantially tangential from the outer periphery of the tape roll and includes a guide surface for separating tape from the tape roll and a termination with a cutting means;

means for hingedly connecting said finger grip piece at one end of said finger grip piece and said cover piece at said side sections; and

tape guide means in said extension wherein said guide means comprises oppositely facing elongated protrusions on the side sections substantially parallel to and proximately spaced from the underside of the top section at the tapered extension, each of said protrusions forming a slot on each of the opposed side sections of the extension and cooperatively providing a channel through which tape is dispensed, said protrusions being spaced apart a distance relative to the width of a tape which causes the tape to deform by bowing which permits the opposite edges of a tape to pass by when the tape is pulled up flatly against the underside of the top section, said protrusions being adapted to engage a narrow portion of the opposite edges of a tape and retain the tape substantially against the underside of the top section at said extension.

2. The tape dispenser of claim 1 wherein said hinge means comprises oppositely arranged keyhole slots on said opposite side sections, said keyhole slots having a substantially straight segment running inward from the edge of said opposite side sections and a circular segment, and outwardly projecting beveled studs at one end of said finger grip piece wherein said beveled studs have at least one flat face, which when aligned with said straight segment allow sliding engagement of said studs in said straight segment to said circular segment, said sliding engagement being prevented when flat face is not aligned with said straight segment, wherein said studs and finger grip piece are rotatable with respect to said keyhole slots and cover piece when said studs are located in said circular segments.

3. The tape dispenser of claim 2 comprising further:

adjustment means cooperating with said hinge means for adjusting the retentive position of said cover piece with respect to said finger grip piece as the tape roll is depleted, said adjustment means comprising a plurality of parallel grooves in the inside of at least one side section of the cover piece and at least one cooperating protrusion on the side of said finger grip piece wherein said protrusion is successively engageable in said parallel grooves as said tape roll is depleted and wherein said parallel grooves are proximate to said keyhole slot and are parallel to said straight segment of said keyhole slot.

4. The tape dispenser of claim 3 wherein said protrusion has a rounded end and said grooves are curved in cross-section.

5. The tape dispenser of claim 1, comprising further:

adjustment means cooperating with said hinge means for adjusting the retentive position of said cover piece with respect to said finger grip piece as the tape roll is depleted, said adjustment means comprising a plurality of parallel grooves in the inside of at least one side section of the cover piece and at least one cooperating protrusion on the side of said finger grip piece wherein said protrusion is successively engageable in said parallel grooves as said tape roll is depleted and wherein said parallel grooves are proximate to said keyhole slot.

6. The tape dispenser of claim 1 comprising further a knife blade having at least one pointed, V-shaped, cutting edge and means in said extension for removably mounting said knife edge in said extension.

7. The tape dispenser of claim 1 having further adjustment means cooperating with said hinge means for adjusting the retentive position of said cover piece with respect to said finger grip piece as the tape roll is depleted.

8. The tape dispenser of claim 7 wherein said adjustment means comprises a lip on at least one of said side sections and a cooperating series of cooperating detents on at least one side of said finger grip piece.

9. The tape dispenser of claim 7 wherein said adjustment means comprises a ridge and groove facing radially projecting from said hinge means on said finger grip piece and a cooperating ridge and groove facing radially projecting from said hinge means on said cover piece.

10. A tape dispenser for dispensing tape from a conventional tape roll having an annular core, said tape dispenser comprising:

a finger grip piece having a crescent configuration insertable within the core of the tape roll, said finger grip piece having a first peripheral portion conforming with a portion of the annular core, and a second peripheral portion adapted for finger contact;

a cover piece having a top section with an underside contoured in part to the outer periphery of a tape roll and having opposite side sections covering in part the sides of a tape roll, said top section and side sections forming a tapered extension at one end of said cover piece;

means for hingedly connecting said finger grip piece at one end of said finger grip piece and said cover piece at said side sections;

tape guide means in said extension wherein said guide means comprises oppositely facing elongated protrusions on the said sections substantially parallel to and proximately spaced from the underside of the top section at the tapered extension to provide a channel through which tape is dispensed, said protrusions being spaced apart a distance relative to the width of a tape which permits the opposite edges of a tape to pass by when the tape is pulled up flatly against the underside of the top section, said protrusions being adapted to engage a narrow portion of the opposite edges of a tape and guide the tape substantially against the underside of the top section as said extension; and

, a knife blade located at the end of said top section at said extension, said extension having means for removably mounting said knife blade, said knife blade having a first edge and a second edge, said blade being selectively mountable in said mounting means with a selected edge projecting for use.

11. The tape dispenser of claim 10 wherein said opposite side sections at said extension project at least to the projecting edge of the knife blade to protect a user from injury.
