Abstract

A tape dispenser (6) is provided (FIGS. 7, 8 and 9) having a movable cover and keeper (27) which slides into a circumferential housing (5) to keep a roll of tape (2) on an axle (3) and hold a brake plate (28) in a circumferential housing (5). The cover (27) has an opening (29) for inserting the thumb to push against the brake plate (28) which operates as a brake when pressed against the roll of tape (2) inside the dispenser (6) by pushing the roll of tape (2) against the housing back (30) to prevent the roll of tape (2) from rotating when a tape-cutting blade (7) at the outside wall of the dispenser is pushed against the tape and given a slight right or left twist to cut it. Plane surfaces (14 and 17) are provided adjacent to the cutting blade (7) for pressing the tape against an object (13) to which tape is being attached to secure firm attachment of the tape before it is cut with the blade. Only one hand is necessary to firmly apply and cut tape by using this dispenser. Once the roll of tape is finished the dispenser (6) is easily refillable by merely putting a finger in an opening (32) which pushes the unit apart for easy replacement of the roll of tape.

Claims

1. A tape dispenser comprising:

a circumferential housing for holding a roll of tape;

a tape-dispensing orifice in the circumferential housing;

a tape-cutting blade extending outwardly from the outside surface of the housing at a select distance from the tape-dispensing orifice;

an axle for holding the roll of tape to one sidewall of the dispenser and extended inwardly towards an opposite sidewall which is movably attachable to the circumferential housing wherein the axle for the roll of tape is expandable in diameter against an inside of a roll of tape positioned thereon by means of a friction brake comprising a cone-shaped expander attachable to the movable sidewall and sized and shaped to fit inside of the expandable axle and to impart outward pressure of the expandable axle against a roll of tape positioned thereon when the movable sidewall is pressed inwardly towards the opposite sidewall to provide friction for arresting tape-dispensing rotation of the roll of tape, thereby holding the tape in position for cutting it with the tape-cutting blade when desired.

2. A tape dispenser according to claim 1 wherein movable attachment of one sidewall of the dispenser to the circumferential housing is comprised of:

a universal-direction hinge member attachable to an outside edge of the circumferential housing and to the movable sidewall such that the movable sidewall can be pivoted in a desired direction to an open position to allow a roll of tape to be positioned on the axle and then pivoted to a closed position and pressed against the roll of tape to provide friction for arresting tape-dispensing rotation of the roll of tape and thereby hold the tape in position for cutting it with the tape-cutting blade when desired.

3. A tape dispenser according to claim 1 and further comprising:

a tape-pressing surface extending between the tape-dispensing orifice and a position selectively near the tape-cutting blade.

4. A tape dispenser according to claim 3 and further comprising:

a tape-dispenser base extending a select distance in a plane tangentially to the outside surface of the circumferential housing from one side of the tape-dispensing orifice.

5. A tape dispenser according to claim 4 and further comprising a planar surface at each side of the tape-dispensing orifice forming a housing base extending a select distance tangentially to the outside surface of the circumferential housing.

6. A tape dispenser according to claim 5 wherein the tape-cutting blade is positioned at a select distance inwardly from an end of the planar surface towards the outside perimeter of the circumferential housing.

7. A tape dispenser according to claim 1 wherein movable attachment of the opposite sidewall of the dispenser to the circumferential housing is comprised of:

a sidewall axle parallel to the axle for the roll of tape and slidably attachable to the circumferential housing at a position selectively outward radially from the axle for the roll of tape; and

pivotal and slidable attachment of the movably-attachable sidewall can be slid outward along the axis of the circumferential housing to open the circumferential housing for allowing a roll of tape to be positioned on the axle for the roll of tape and such that the movably-attachable sidewall can be slid inwardly on the sidewall axle against a roll of tape positioned on the axle for the roll of tape to provide friction for arresting tape-dispensing rotation of the roll of tape, thereby holding the tape in position for cutting it with the tape-cutting blade when desired.

8. A tape dispenser according to claim 1 wherein movable attachment of one sidewall of the dispenser to the circumferential housing is comprised of:

a sidewall hinge attachable to an outside edge of the circumferential housing and pivotally attachable to the movable sidewall such that the movable sidewall can be pivoted to an open position to allow a roll of tape to be positioned on the axle and then pivoted to a closed position and pressed against the roll of tape to provide friction for arresting tape-dispensing rotation of the roll of tape and thereby hold the tape in position for cutting it with the tape-cutting blade when desired.

9. A tape dispenser comprising:

a circumferential housing for holding a roll of tape;

a tape-dispensing orifice in the circumferential housing;

a tape-cutting blade extending outwardly from the outside surface of the housing at a select distance from the tape-dispensing orifice;

an axle for holding the roll of tape to one sidewall of the dispenser and extended inwardly towards an opposite sidewall which is movably attachable to the circumferential housing;

wherein movable attachment of the opposite sidewall of the dispenser to the circumferential housing is comprised of;

a sidewall axle parallel to the axle for the roll of tape and slidably attachable to the circumferential housing at a position selectively outward radially from the axle for the roll of tape; and

pivotal and slidable attachment of the movably-attachable sidewall can be slid outward along the axis of the circumferential housing to open the circumferential housing for allowing a roll of tape to be positioned on the axle for the roll of tape and such that the movably-attachable sidewall can be slid inwardly on the sidewall axle against a roll of tape positioned on the axle for the roll of tape to provide friction for arresting tape-dispensing rotation of the roll of tape, thereby holding the tape in position for cutting it with the tape-cutting blade when desired;

wherein the opposite sidewall has an opening therein for insertion of a finger to push against a roll of tape; and

a flat plate positioned between the opposite sidewall and the roll of tape so that the flat plate will act as a brake when pushed against the roll of tape and pushed by a finger inserted in the round opening in the opposite sidewall.
