Abstract

A tape dispenser for applying adhesive tape to a substrate surface. The dispenser includes an exterior application surface with an opening therein. A plurality of rotatable cylindrical rollers are mounted within the housing, wherein the surfaces of the rollers coact with each other and the tape surfaces to retain, guide and feed the tape through the tape dispensing opening to the exterior application surface. At least two of the plurality of rollers are opposed rollers that engage the tape surfaces therebetween. The outer surface of at least one of the plurality of rollers protrudes through the opening enabling frictional contact of the roller surface with the substrate surface. When the dispenser is drawn over the surface, the outer surface of the this roller engages and rolls over the substrate surface. It also coacts with the outer surfaces of the other rollers, causing them to grip the tape and feed it through the opening, enabling the adhesive tape to be applied to the substrate surface.

Claims

1. A tape dispenser for applying tape to a substrate surface, the tape having a first surface with a pressure sensitive adhesive thereon and a second surface, the dispenser comprising:

a housing suitable for holding and dispensing a roll of tape, the housing including an exterior application surface having a tape dispensing opening therein;

a plurality of rotatable cylindrical rollers with outer surfaces rotatably mounted within the housing, wherein the surfaces of the rollers coact with each other and the tape surfaces to retain, guide and feed the tape through the tape dispensing opening to the exterior application surface, wherein at least two of the plurality of rollers are opposed rollers that engage the tape surfaces therebetween;

wherein the outer surface of at least one of the plurality of rollers protrudes through the application surface on one side of the opening enabling frictional contact of the roller surface with the substrate surface;

wherein a cutting blade having a cutting edge is fixedly mounted to the application surface, the cutting edge facing into the housing;

whereby when the application surface of the tape dispenser is drawn over the substrate surface in one direction, the outer surface of the roller frictionally engages the substrate surface causing the roller to roll along the substrate surface and to coact and drive the outer surfaces of the other rollers of the plurality of rollers causing them to grip the surfaces of the tape to thereby feed the tape through the opening enabling the first surface of the tape with the pressure sensitive adhesive thereon to contact the substrate surface and adhere thereto, and when the dispenser is moved in a direction different than the one direction, the tape is cut by the blade and retained in the housing between the two opposed rollers.

2. The tape dispenser of claim 1, wherein the housing comprises a left housing member and a right housing member and a portion of these housing members are removably joined to each other to permit the insertion and removal of the roll of tape from the housing.

3. The tape dispenser of claim 1, wherein the housing comprises a left housing member and a right housing member and a portion of the housing members are removably joined to each other to permit the insertion and removal of the roll of tape from the housing and the remaining portions of the housing members are permanently joined to each other to permanently maintain the plurality of rollers in the housing.

4. The tape dispenser of claim 1, wherein the roller in contact with the first surface with the adhesive thereon has a reduced diameter over a portion of its length that is not in contact with the first surface.

5. The tape dispenser of claim 1, wherein the roller in contact with the first surface with the adhesive thereon has a reduced diameter over a substantial portion of its length that is not in contact with the first surface.

6. A tape dispenser for applying tape to a substrate surface, the tape having a first surface with a pressure sensitive adhesive thereon and a second surface, the dispenser comprising:

a housing suitable for holding and dispensing a roll of tape, the housing including an exterior application surface having a tape dispensing opening therein;

a plurality of rotatable cylindrical rollers with outer surfaces rotatably mounted within the housing, wherein the surfaces of the rollers coact with each other and the tape surfaces to retain, guide and feed the tape through the tape dispensing opening to the exterior application surface, wherein at least two of the plurality of rollers are opposed rollers that engage the tape surfaces therebetween;

wherein the outer surface of at least one of the plurality of rollers protrudes through the application surface on one side of the opening enabling frictional contact of the roller surface with the substrate surface, and the outer surface of another of the rollers protrudes through the application surface on the other side of the opening to contact the second surface of the tape as it is fed through the opening;

wherein a cutting blade having a cutting edge is fixedly mounted to the application surface, the cutting edge facing into the housing;

whereby when the application surface of the tape dispenser is drawn over the substrate surface in one direction, the outer surface of the roller frictionally engages the substrate surface causing the roller to roll along the substrate surface and to coact and drive the outer surfaces of the other rollers of the plurality of rollers causing them to grip the surfaces of the tape to thereby feed the tape through the opening enabling the first surface of the tape with the pressure sensitive adhesive thereon to contact the substrate surface and adhere thereto, the outer surface of the other roller contacting the second surface of the tape to apply pressure to the tape causing the first surface of the tape with the pressure sensitive adhesive thereon to adhere to the substrate, and when the dispenser is moved in a direction different than the one direction, the tape is cut by the blade and retained between the two opposed rollers.

7. A tape dispenser for applying tape to a substrate surface, the tape having a first surface with a pressure sensitive adhesive thereon and a second surface, the dispenser comprising:

a housing suitable for holding and dispensing a roll of tape, the housing including an exterior application surface having a tape dispensing opening therein;

a plurality of rotatable cylindrical rollers with outer surfaces rotatably mounted within the housing, wherein the surfaces of the rollers coact with each other and the tape surfaces to retain, guide and feed the tape through the tape dispensing opening to the exterior application surface, wherein at least two of the plurality of rollers are opposed rollers that engage the tape surfaces therebetween;

wherein the outer surface of at least one of the rollers protrudes through the application surface on one side of the opening initially enabling frictional contact of the roller surface with the substrate surface and then subsequently enabling contact with the second surface of the tape as it is fed through the opening;

wherein a cutting blade having a cutting edge is fixedly mounted to the application surface, the cutting edge facing into the housing;

whereby when the application surface of the tape dispenser is drawn over the substrate surface in one direction, the outer surface of the roller frictionally engages the substrate surface causing the roller to roll along the substrate surface and to coact with at least one other roller to grip the surfaces of the tape to thereby feed the tape through the opening, enabling the first surface of the tape with the pressure sensitive adhesive thereon to contact the substrate surface and adhere thereto, the outer surface of the roller then contacting the second surface of the tape to apply pressure to the tape causing the first surface of the tape with the pressure sensitive adhesive thereon to adhere to the substrate, and when the dispenser is moved in a direction different than the one direction, the tape is cut by the blade and retained between the two opposed rollers.
