Tape dispenser with cutter assembly and protrusion

A household tape dispenser for dispensing Biaxially-Oriented Polypropylene (BOPP) adhesive tape;

• said tape dispenser comprising:
• a first side member having a first axle portion extending outwardly from an interior surface thereof;
• a second side member having a second axle portion extending outwardly from an interior surface thereof, and wherein the first and second side members are engageable with each other and when so engaged, the first and second axle portions are adapted to support a hub of a roll of BOPP tape thereon such that the roll of tape is rotatable about an axis extending through the first and second axle portions;
• a cutter assembly provided on a front end of the dispenser a spaced distance forwardly from the first and second axle portions;
• said cutter assembly including:
• a base extending between the first and second side members and having a front region oriented substantially vertical with respect to a top edge of each of the first and second side members, wherein the top edges are located adjacent the base;
• a row of plastic teeth
• adapted to perforate the BOPP tape and sever a desired length of the tape from the roll;
• wherein the row of teeth extends upwardly from the front region and includes at least a first tooth, a second tooth and a third tooth, wherein the second tooth is adjacent the first tooth and the third tooth is adjacent the second tooth, and wherein each of the first, second and third teeth includes:
• a left front face disposed in a first plane where the first plane is oriented at a first angle relative to the front region of the base;
• a right front face disposed in a second plane where the second plane is oriented at a second angle relative to the front region of the base;
• wherein the left and right front faces meet along a single central front edge and the first plane is angled relative to the second plane;
• and the front edge extends upwardly from the front region of the base and each of the left and right front faces angles rearwardly away from the front edge;
• a left rear face disposed in a third plane;
• and
• a right rear face disposed in a fourth plane;
• and wherein the left and right rear faces are angled relative to each other and meet along a single central rear edge and wherein the third and fourth planes are angled relative to each other and the left and right rear faces angle forwardly away from the rear edge;
• and wherein the rear edge is opposite the front edge;
• and wherein the first, second, third and fourth planes intersect each other at a discrete point and which point forms an uppermost tip of the tooth;
• and wherein a length of the central rear edge is shorter than a length of the central front edge;
• and
• a protrusion formed on the front end of the dispenser rearwardly of the row of teeth and forwardly of the first and second axle portions.

In combination,

• a roll of Biaxially-Oriented Polypropylene (BOPP) adhesive tape, wherein the roll includes a cylindrical hub with an extended length of BOPP tape wound thereon;
• a tape dispenser for retaining the roll of BOPP tape therein and for selectively dispensing desired lengths of tape therefrom, wherein said tape dispenser comprises:
• a first side member having an interior surface;
• a first axle portion extending outwardly from the interior surface;
• a second side member having an interior surface;
• a second axle portion extending outwardly from the interior surface of the second side member, wherein the first and second side members are engageable with each other and when so engaged the first and second axle portions are engaged with each other and the roll of tape is received thereon and is rotatable about an axis extending through the first and second axle portions;
• and
• a cutter assembly provided on a front end of the dispenser and extending between the interior surfaces of the first and second side members;
• said cutter assembly including:
• a base extending between the first and second side members and having a front region oriented substantially vertical with respect to a top edge of each of the first and second side members, wherein the top edges are located adjacent the base;
• a row of plastic teeth extending upwardly from the front region, each tooth
• having a tip configured to perforate the BOPP tape and wherein the teeth are adapted sever a desired length of the tape from the roll;
• and wherein the row of teeth includes at least a first tooth, a second tooth and a third tooth, wherein the second tooth is adjacent the first tooth and the third tooth is adjacent the second tooth, and wherein each of the first, second and third teeth includes:
• a left front face disposed in a first plane where the first plane is oriented at a first angle relative to the front region of the base;
• a right front face disposed in a second plane where the second plane is oriented at a second angle relative to the front region of the base;
• wherein the left and right front faces meet along a single central front edge and the first plane is angled relative to the second plane;
• and the front edge extends upwardly from the front region of the base and each of the left and right front faces angles rearwardly away from the front edge;
• a left rear face disposed in a third plane;
• and
• a right rear face disposed in a fourth plane;
• and wherein the left and right rear faces are angled relative to each other and meet along a single central rear edge and wherein the third and fourth planes are angled relative to each other and the left and right rear faces angle forwardly away from the rear edge;
• and wherein the rear edge is opposite the front edge;
• and wherein the first, second, third and fourth planes intersect each other at a discrete point and which point forms an uppermost tip of the tooth;
• and wherein a length of the central rear edge is shorter than a length of the central front edge;
• a protrusion formed on the front end of the dispenser rearwardly of the row of teeth and forwardly of the first and second axle portions.
