Abstract
A tape dispenser of the type having a cutting blade mounted on the upper end of a cutting bar with a cutting bar face below and generally parallel to the blade and a blade guard slidably mounted on the cutting bar face for movement between blade-covering and blade-exposing positions. A spring tension element is positioned on the blade guard so that it tends to push a lower end of the blade guard away from the cutting bar face and to push an upper blade-covering end of the blade guard toward the cutting bar face when the blade guard is in the blade covering position.
Claims10
In a tape dispenser having a spool portion for dispensing a tape, a cutting portion;
- a cutting blade mounted on the cutting portion and adapted to cut tape fed from the spool portion,
- a blade guard slidably mounted on the cutting portion adjacent to the cutting blade for selective movement between blade-covering and blade-exposing positions, wherein the blade guard and the cutting portion are configured to selectively retain the blade guard in the blade covering and blade exposing positions;
- the cutting portion includes a cutting bar supporting the cutting blade and with a face extending axially from the cutting blade and the blade guard is slidably mounted to the face of the cutting bar;
- wherein the blade guard further includes at least one spring element in sliding tensioned contact with the cutting face,
- wherein the at least on spring element is positioned on the blade guard so that it tends to push a lower end of the blade guard away from the cutting bar face and to push an upper blade-covering end of the blade guard toward the cutter bar face when the blade guard is in the blade covering position;
- wherein the cutting bar face has a slot and the blade guard comprises a T-shaped follower with a stem that extends through the slot and ears that are retained on a rear surface of the cutting bar behind the face for sliding movement of the blade guard on the cutting bar.
A tape dispenser adapted to rotatably house a roll of tape, comprising:
- two unitary sidewalls,
- a top wall portion extending axially between the sidewalls and connecting the sidewalls above the outer diameter of a roll of tape contained in the dispenser;
- a spool support extending axially between the sidewalls and connecting the sidewalls through a spool portion of a roll of tape contained in the dispenser;
- and
- a cutting bar extending axially between the sidewalls and connecting the sidewalls together at a forward end of the dispenser, the cutting bar mounting a cutting element for cutting tape and forming a tape retainer surface adjacent to the cutting element for adhesively securing a leading cut end of tape from a roll of tape contained in the dispenser subsequent to severing a leading portion of the tape from the cut end:
- the cutting bar being spaced circumferentially from a forward end of the top wall portion to define a tape-feed opening between the top wall portion and the cutting bar;
- wherein the dispenser is radially split into two axially registering and rotationally mating halves that have rotationally mating locking structures on each of the top wall portion, the spool support, and the cutting bar that releasably interlock the mating halves together as the mating halves are rotated relative to each other.
