Abstract

A holder and dispenser for knife blades which includes a sliding partition biased toward a discharge opening by rubber bands in a double loop configuration. The double looped configuration orients the rubber bands which loop around the back of the holder, and loop adjacent the front of the holder and loop around the back of the sliding partition. The rubber bands are oriented in slots or grooves in the holder and dispenser for protection. The sliding partition bias blades held in the holder toward a discharge slot through which blades are slid laterally.

Claims

1. An improved holder and dispenser for blades having a blade retaining cavity in which blades are biased towards an ejection means adjacent a discharge slot disposed on a front wall of said cavity wherein the improvement comprises:

(a) at least one rubber band which contacts at more than one point, a free-floating sliding partition oriented in the cavity to bias blades toward said ejection means; and

(b) said rubber band being oriented around a back of said holder looped adjacent said front wall and looped around a back side of said sliding partition; and

(c) all portions of the peripheral surface of said rubber band being maintained free of contact with all other portions of the peripheral surface of said rubber band.

2. The improved holder and dispenser of claim 1, wherein portions of the rubber band are oriented in grooves formed in said holder and in said sliding partition.

3. The improved holder and dispenser of claim 1, wherein said at least one rubber band is looped around rollers set in said holder adjacent said front.

4. The improved holder and dispenser of claim 1, wherein said at least one rubber band comprises two rubber bands.

5. The improved holder and dispenser of claim 1, wherein said ejection means comprises an ejector, slidingly affixed to said front wall of said holder, having a lip extending therefrom to engage a blade held in said cavity, said blade biased toward said ejection means by said at least one rubber band whereby sliding said ejection means forces a blade out of said cavity through said discharge slot.

6. The improved holder and dispenser of claim 1, wherein said ejection means comprises a finger slot in said front wall of said holder which exposes a portion of a blade held in said cavity and biased toward said finger slot by said at least one rubber band, whereby said blade is manually forced out of said cavity through said discharge slot.

7. A holder and dispenser for blades comprising:

(a) a rear wall;

(b) top, bottom and sides extending from said rear wall defining a longitudinal cavity;

(c) a sliding partition adapted to fit within said cavity;

(d) a front cover adapted to be affixed to said top, bottom and sides to seal said cavity, including means to slide blades laterally through a discharge slot; and

(e) at least one rubber band is looped around said rear wall extends along said top and bottom, is looped adjacent said front cover, and is looped around a back side of said sliding partition.

8. The holder and dispenser of claim 7, wherein said at least one rubber band extends along grooves on an inside surface of said top and said bottom and is looped around rollers set in said top and said bottom adjacent said front cover.

9. The holder and dispenser of claim 7, wherein said means to dispense blades includes an ejector, slidingly affixed to said front cover having a lip extending therefrom to engage a blade held in said cavity, said blade biased toward said ejector by said at least one rubber band acting on said sliding partition whereby sliding said rubber ejector forces a blade out of said cavity through said discharge slot.

10. The holder and dispenser of claim 7, wherein said means to dispense blades includes a finger slot in said front cover which exposes a portion of a blade held in said cavity and biased toward said finger slot by said sliding partition, whereby said blade is manually forced out of said cavity through said discharge slot.

11. The holder and dispenser of claim 7, employing two substantially parallel rubber bands.

12. The holder and dispenser of claim 7 further including a used blade receiving opening adjacent said rear wall.

13. The holder and dispenser of claim 7 including a sight opening along at least one of said sides.

14. The holder and dispenser of claim 7 having a cross-sectional geometric shape of a trapezoid adapted to hold and dispense utility knife blades.

15. An improved holder and dispenser for blades having a blade retaining cavity in which blades are biased toward an ejection means adjacent a discharge slot wherein the improvement comprises:

at least one rubber band which contacts, at more than one point, a free-floating sliding partition oriented in said cavity to provide a self-orienting biasing means to bias blades toward said ejection means wherein said rubber band is arranged in a double loop configuration by orienting said rubber band around a back of said holder, looped adjacent a front of said holder and looped around a backside of said sliding partition.

16. The improved holder and dispenser of claim 15 wherein said at least one rubber band is oriented in grooves in said holder and in said sliding partition.

17. The improved holder and dispenser of claim 15, wherein said rubber band is looped around rollers set in said holder adjacent said front.
