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 a wound adhesive tape 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 cantilevered from a first inner surface on the first side member, wherein during a braking action the first brake spoke contacts the hub and the wound adhesive tape; and

wherein the first brake spoke has a radial length measured relative to the hub axis, wherein the radial length is at least as long as an annular sidewall formed from a new roll of the wound adhesive tape.

2. The tape dispenser of claim 1, further comprising a simultaneous contact between the first brake spoke and the hub and the wound adhesive tape during the braking action.

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

a second brake spoke extending cantilevered from a second inner surface on the second side member and extending towards the first brake spoke, wherein the second brake spoke contacts the hub and the adhesive tape during a braking action opposite the first brake spoke.

4. The tape dispenser of claim 3, further comprising a radial length of the second brake spoke equal to the radial length of the first brake spoke measured relative to the hub axis.

5. The tape dispenser of claim 3, wherein the first brake spoke includes an end wall that tapers radially inward relative to the hub axis and wherein the second brake spoke includes an end wall that tapers radially inward relative to the hub axis.

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

an imaginary radial line extending radially from the hub axis;

wherein the imaginary radial line intersects the entire first brake spoke.

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

a plurality of brake spokes connected to the first side member, wherein the first brake spoke is included in the plurality of brake spokes, and wherein there are six total brake spokes.

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

a gap defined between the first brake spoke and the wound adhesive tape;

wherein the gap is narrow near a radially distal portion of the gap relative to the hub axis and the gap is wider near a radially proximal portion of the gap relative to the hub axis.

9. The tape dispenser of claim 1, wherein the first brake spoke includes a terminal end that tapers in a narrowing manner from a radial distal end to a radial proximal end to define a tapered wall relative to the hub axis.
