Abstract

A tape dispenser housing wound adhesive tape includes a brake spoke tapering (i.e., narrowing) from a distal radial end to a proximal radial end relative to a tape rotational axis, wherein the brake spoke effectuates the braking of wound adhesive tape on a hub by contacting the wound adhesive tape, the hub, or both simultaneously.

Claims

1. A tape dispenser comprising:

a first side member and an opposing second side member;

an axle extending between the first and second side members defining a hub axis;

a hub carrying wound adhesive tape therearound configured to be unwound and dispensed, and the hub positioned concentric around the axle to rotate about the hub axis;

a first brake spoke extending from a first inner surface on the first side member and a free end wall on the first brake spoke, wherein when the first side member is flexed, and the end wall effectuates braking of the adhesive tape and the hub by contacting one of the following (i) the adhesive tape, (ii) the hub, and (iii) the adhesive tape and the hub simultaneously;

an imaginary radial line extending radially from the hub axis, wherein the imaginary radial line intersects the first brake spoke at only one point;

wherein the first brake spoke is arcuate and includes an apex, and the imaginary radial line intersects the apex; and

an arcuate second brake spoke adjacent the arcuate first brake spoke, and the second brake spoke terminating at a tail end, wherein the imaginary radial line intersects the tail end.

2. The tape dispenser of claim 1, further comprising:

a second brake spoke extending from the first inner surface adjacent the first brake spoke;

wherein the imaginary radial line intersects the second brake spoke.

3. The tape dispenser of claim 2, wherein the imaginary radial line intersects the second brake spoke at only one point.

4. The tape dispenser of claim 1, wherein the first brake spoke forms an arcuate profile when viewed from the first side.

5. The tape dispenser of claim 4, wherein the arcuate first brake spoke is asymmetrically parabolic in shape.

6. The tape dispenser of claim 1, wherein the free end wall tapers from a wider distal end to a narrower proximal end relative to the hub axis.

7. A tape dispenser comprising:

a first side member and an opposing second side member;

an axle extending between the first and second side members defining a hub axis;

a hub carrying wound adhesive tape therearound configured to be unwound and dispensed, and the hub positioned concentric around the axle to rotate about the hub axis;

a first brake spoke extending from a first inner surface on the first side member and a free end wall on the first brake spoke, wherein when the first side member is flexed, and the end wall effectuates braking of the adhesive tape and the hub by contacting the adhesive tape and the hub simultaneously; and

an imaginary radial line extending radially from the hub axis, wherein the imaginary radial line intersects the first brake spoke at only one point.

8. The tape dispenser of claim 7, further comprising:

wherein the first brake spoke is arcuate and includes an apex, and the imaginary radial line intersects the apex; and

an arcuate second brake spoke adjacent the arcuate first brake spoke, and the second brake spoke terminating at a tail end, wherein the imaginary radial line intersects the tail end.

9. The tape dispenser of claim 7, further comprising:

a second brake spoke extending from the first inner surface adjacent the first brake spoke;

wherein the imaginary radial line intersects the second brake spoke.

10. The tape dispenser of claim 9, wherein the imaginary radial line intersects the second brake spoke at only one point.

11. The tape dispenser of claim 7, wherein the first brake spoke forms an arcuate profile when viewed from the first side.

12. The tape dispenser of claim 11, wherein the arcuate first brake spoke is asymmetrically parabolic in shape.

13. The tape dispenser of claim 7, wherein the free end wall tapers from a wider distal end to a narrower proximal end relative to the hub axis.
