Abstract

A tape dispenser for securing a desired length of pressure sensitive tape onto a surface and severing the length from a tape roll held within the dispenser. The dispenser includes an applicator element having a tape support bar at the lower end thereof, a tape gripping member pivotally mounted on the lower end of the applicator forwardly of the tape support bar, a tape cutting edge disposed in the lower portion of the device and a spring member for raising the actuator after the desired length of tape has been paid out from the dispenser and urging the tape support bar against the tape gripping member to grip the tape therebetween and pull the tape over the cutting edge as the applicator moves upwardly within the dispenser severing the length of tape secured to the surface from the tape roll.

Claims

1. A pressure sensitive tape dispenser comprising a housing, means for mounting a roll of pressure sensitive tape within said housing, a tape cutting member disposed within said housing, a manually operative applicator element slidably mounted within said housing, a tape support bar carried by said applicator element, a tape gripping member pivotally mounted within said housing and means for selectively biasing said tape support bar and said tape gripping member in a tape gripping relationship and for raising said applicator element within said housing such that tape can be freely drawn from said roll between said tape gripping bar and said tape gripping member, held therebetween and pulled thereby over said cutting member thereby severing the tape.

2. The combination of claim 1 wherein said tape gripping member is pivotally mounted on said applicator element for movement therewith and with respect thereto.

3. The combination of claim 2 wherein said selective biasing means comprises a spring member for urging said applicator element upwardly and forwardly within said housing, a first guide means for directing the movement of said applicator element as said element is slidably moved within said housing and a second guide means for directing the pivotal movement of said tape gripping member with respect to said applicator element.

4. A pressure sensitive tape dispenser comprising a housing, means for mounting a roll of pressure sensitive tape within said housing, a tape cutting member disposed within said housing, a manually operative applicator element slidably mounted within said housing, a tape support bar carried by said applicator element, a tape gripping member defining a tape gripping bar, said tape gripping member being mounted for pivotal and limited linear movement on said applicator element such that said tape gripping bar is disposed forwardly and substantially parallel with said tape support bar, biasing means for urging said applicator element upwardly within said housing, and guide means for directing said tape gripping bar from said tape support bar as said applicator element is moved downwardly within said housing thereby allowing tape to be withdrawn from said housing and, upon said applicator element being raised by said biasing means, for directing said tape suppport bar against said gripping bar for gripping said tape therebetween and pulling said tape over said cutting member thereby severing said tape from the tape roll.

5. The combination of claim 4 wherein said tape gripping member is of a "U"-shaped configuration defining upstanding leg portions and tape gripping bar extending therebetween, said upstanding leg portions being mounted on said tape applicator element.

6. The combination of claim 4 wherein said guide means comprises a first guide surface, a first guide member carried by said applicator element and bearing against said first guide surface, a second guide surface disposed forwardly in said housing of said first guide surface and a second guide member carried by said tape gripping member, said tape gripping bar and said tape support bar being pivoted into and out of tape gripping engagement as said first and second guide members are moved along said first and second guide surfaces.

7. The combination of claim 6 wherein said applicator element includes a relief area disposed forwardly of and above said tape support bar such that upon said tape being pulled from said housing, said tape gripping bar is moved forwardly and upwardly into said relief area by said tape.

8. A pressure sensitive tape dispenser comprising a housing, means for mounting a roll of pressure sensitive tape within said housing, a tape cutting member disposed within said housing, an applicator element slidably mounted within said housing, said element including depending leg portions and a tape support bar extending therebetween, a "U"-shaped gripping member defining upstanding leg portions and a tape gripping bar extending therebetween, said upstanding leg portions being mounted for pivotal and limited linear movement on the depending leg portions of said applicator element such that said tape gripping bar is disposed forwardly of and substantially parallel with said tape support bar within said housing, biasing means for urging said applicator element upwardly and forwardly within said housing, and guide means for directing said tape gripping bar from said tape support bar as said applicator element is moved downwardly within said housing thereby allowing tape to be withdrawn from said housing and, upon said applicator element being raised by said biasing means, for directing said tape support bar against said gripping bar for gripping said tape therebetween and pulling said tape over said cutting member thereby severing said tape from the tape roll.

9. The combination of claim 8 wherein said guide means comprises a first guide surface, a first guide member carried by said applicator element and bearing against said first guide surface, a second guide surface disposed forwardly in said housing of said first guide surface and a second guide member carried by said tape gripping member, said tape gripping bar and said tape support bar being pivoted into and out of tape gripping engagement as said first and second guide members are moved along said first and second guide surfaces.

10. The combination of claim 8 wherein said applicator element includes a relief area disposed forwardly of and above said tape support bar such that upon said tape being pulled from said housing, said tape gripping bar is moved forwardly and upwardly into said relief area by said tape.

11. The combination of claim 8 wherein said housing includes a forward wall portion, said tape cutting member being defined by the end of said forward wall portion and including a rearwardly projecting pointed tooth member and a tape cutting surface extending laterally therefrom and substantially parallel with said tape gripping bar and said tape support bar.

12. The combination of claim 11 wherein said cutting surface tapers outwardly from said projecting tooth member at an angle of about 1 degree with respect to the central axis of said tape gripping bar.

13. The combination of claim 11 wherein said tape support bar defines a forward tape gripping surface and said tape gripping bar defines a rear gripping surface, said surfaces each diverging from the ends thereof adjacent said cutting tooth at angles of about two to five degrees to facilitate the bowing of tape therebetween during the cutting of said tape by said cutting member.
