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;

a tapered wall on the first brake spoke, wherein when the first side member is flexed, and the tapered wall effectuates braking of the adhesive tape and the hub, wherein the tapered wall defines a terminal end of the first brake spoke and tapers in a narrowing manner from a radial distal end of the tapered wall to a radial proximal end of the tapered wall relative to the hub axis; and

a radial linear dimension of the first brake spoke relative to the hub axis that is greater than a radial linear dimension of the hub.

2. The tape dispenser of claim 1, wherein the tapered wall has the radial linear dimension that contacts the adhesive tape and hub simultaneously during braking.

3. The tape dispenser of claim 1, wherein the tapered wall has the radial linear dimension that contacts only the adhesive tape during braking.

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

a second brake spoke extending from a second inner surface on the second side member; and

a tapered wall on the second brake spoke, wherein when the second side member is flexed, and the tapered wall on the second brake spoke effectuates braking of the adhesive tape and the hub.

5. The tape dispenser of claim 4, further comprising a radial linear dimension of the second brake spoke equal to the first brake spoke.

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 first brake spoke at two or fewer points.

7. 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.

8. 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 first brake spoke at only one point.

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

a plurality of brake spokes connected to the first side member, wherein the first brake spoke included in the plurality of brake spokes;

wherein the imaginary radial line intersects the first brake spoke at one point and intersects an adjacent brake spoke at one point.

10. 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 at least five total brake spokes.

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

a gap defined between the tapered wall 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.

12. A tape dispenser comprising a brake spoke tapering 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 adhesive tape and hub simultaneously.

13. 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;

a tapered wall on the first brake spoke, wherein when the first side member is flexed, and the tapered wall effectuates braking of the adhesive tape and the hub;

a gap defined between the tapered wall 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; and

a radial linear dimension of the first brake spoke relative to the hub axis that is greater than a radial linear dimension of the hub.

14. 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;

a tapered wall on the first brake spoke, wherein when the first side member is flexed, and the tapered wall effectuates braking of the adhesive tape and the hub;

a radial linear dimension of the first brake spoke relative to the hub axis that is greater than a radial linear dimension of the hub;

an imaginary radial line extending radially from the hub axis;

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

15. 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;

a tapered wall on the first brake spoke, wherein when the first side member is flexed, and the tapered wall effectuates braking of the adhesive tape and the hub;

a radial linear dimension of the first brake spoke relative to the hub axis that is greater than a radial linear dimension of the hub;

an imaginary radial line extending radially from the hub axis;

wherein the imaginary radial line intersects the first brake spoke at only one point;

a plurality of brake spokes connected to the first side member, wherein the first brake spoke included in the plurality of brake spokes; and

wherein the imaginary radial line intersects the first brake spoke at one point and intersects an adjacent brake spoke at one point.
