Abstract

A tape dispenser that reduces accidental injury from contact with a sharp blade used to cut and separate tape from the dispenser when affixing the tape to a surface. The cutting blade, fixed at an angle some distance above an opening, or above the edge of a flexible plate, is not exposed unless enough pressure is applied to bend plate far enough to expose blade through and beyond the flexible plate. This invention provides a simpler, safer, more cost effective method of dispensing, affixing and cutting any material in tape form.

Claims

1. A tape applicator comprising:

a frame carrying a roll of tape;

a first relatively rigid plate extending from the frame carrying a tape cutting blade thereon;

a second more flexible plate extending from the frame capable of deflection upon application of pressure upon the frame by a user of the tape applicator, the second plate containing an aperature therein of sufficient dimension to allow passage of the cutting blade therethrough when pressure is applied to the frame;

the first plate extending a greater distance from the frame than the second plate and in close parallel alignment therewith whereby user contact with the blade is minimized.

2. The tape applicator of claim 1 wherein the second plate contains at least two tabs on the underside thereof to retain the tape in a position adjacent the frame after it is cut off by the cutting blade.

3. The tape applicator of claim 1 wherein the second plate extends a greater distance from the frame than the first plate.

4. The tape applicator of claim 1 wherein the aperature in the second plate and the cutting blade on the first plate are located at essentially the same distance from the frame.

5. The tape applicator of claim 1 wherein the outer end of the second plate includes a rounded edge to facilitate adherence of tape dispensed from the roll of tape to a surface.

6. A tape applicator comprising:

a frame carrying a roll of tape;

a first, relatively rigid plate extending from the frame carrying a tape cutting blade thereon;

a second, more flexible, plate extending from the frame and having a width at least as great as that of the cutting blade and terminating at a point in close proximity to the blade, thereby limiting contact with the blade by a user of the tape applicator.

7. The tape applicator of claim 6 wherein the second plate deflects in a direction toward the first plate upon application of pressure upon the frame by a user of the tape applicator.

8. The tape applicator of claim 7 wherein the cutting blade extends from a bottom surface of the first plate a greater distance than the thickness of the second plate whereby the blade is in contact with the tape dispensed from the tape roll when the second plate is deflected.

9. The tape applicator of claim 6 wherein the second plate contains at least two tabs on the underside thereof to retain the tape in a position adjacent to the frame after it is cut off by the cutting blade.

10. The tape applicator of claim 6 wherein the second plate extends a lesser distance from the frame than the first plate.

11. The tape applicator of claim 6 wherein the outer end of the second plate includes a rounded edge to facilitate adherence of tape dispensed from the roll of tape onto a surface.
