Abstract

Liquid dispensing applicators adapted to be mounted to a container of lubricating oil or degreaser and used to lubricate or apply degreaser to a drive chain of a bicycle or motorcycle are disclosed. The applicator housing has an open slot to receive the chain. A wear-resistant and absorbent pad is positioned within the housing to engage the chain. A conduit between the absorbent pad and the container transmits liquid to the absorbent pad such that the chain can be cleaned or lubricated.

Claims (37)

1. A lubricant applicator for applying a fluid to a chain, comprising:

a body defining a cavity, wherein the body comprise extensions only in a first direction comprising undercuts configured to retain a fluid transfer pad; and

a container interface comprising a fluid conduit, wherein,

the container interface is configured to securely mechanically couple to a fluid container; and

the fluid conduit is configured to fluidly couple a fluid contained in the fluid container to a fluid transfer pad.

2. The applicator of claim 1 , comprising a guide extending from both sides of the body in the lengthwise direction.

3. The applicator of claim 1 , wherein the chain comprises a roller chain.

4. The applicator of claim 1 , comprising a fluid transfer pad retained within the cavity.

5. The applicator of claim 4 , wherein the fluid transfer pad is absorbent.

6. The applicator of claim 1 , wherein the fluid container interface comprises a flip-top spout dispenser.

7. The applicator of claim 1 , wherein the container interface is configured to securely mechanically couple to a spout of a flip-top spout dispenser.

8. The applicator of claim 1 , wherein the container interface is configured to replace a flip-top spout dispenser of a fluid container comprising a neck and a flip-top spout dispenser.

9. The applicator of claim 8 , wherein the container interface is configured to securely mechanically couple to the neck.

10. The applicator of claim 1 , comprising a cavity adjacent the fluid conduit configured to retain a diaphragm.

11. The applicator of claim 1 , comprising a diaphragm adjacent the fluid conduit.

12. The applicator of claim 11 , wherein the diaphragm is porous.

13. The applicator of claim 11 , wherein the diaphragm comprises an elastomeric valve comprising at least one sealable opening.

14. The applicator of claim 1 , wherein the container interface comprises threads configured to securely mechanically connect to a neck of a fluid container.

15. The applicator of claim 1 , wherein the container interface is configured to securely mechanically connect to a neck of the container with a compression fit.

16. The applicator of claim 1 , comprising a chain guide.

17. The applicator of claim 1 , comprising a chain guide, wherein the chain guide comprises at least one guide rib on either side of the cavity in the lengthwise direction.

18. The applicator of claim 1 , wherein the container interface comprises a valve.

19. The applicator of claim 1 , wherein the applicator is configured to securely mechanically and fluidly connect to a spray-can type lubricant container.

20. The applicator of claim 1 , comprising an attachment yoke configured to mount to a spray-can.

21. The applicator of claim 1 , comprising a bracket mechanically connected to the applicator, wherein the bracket is configured to mechanically connect to a spray-type lubricant container.

22. The applicator of claim 1 , comprising a tube having a first end fluidly connected to the fluid conduit and a second end for fluidly coupling to a discharge spout of a spray container.

23. The applicator of claim 1 , configured to securely mechanically and fluidly couple to a push/pull-type lubricant dispenser without a valve cap.

24. A fluid dispenser comprising the applicator of claim 1 .

25. The dispenser of claim 24 , comprising a fluid container securely mechanically coupled to the container interface, wherein fluid within the fluid container is fluidly coupled to the fluid conduit.

26. The dispenser of claim 25 , wherein the fluid container is configured to dispense the fluid when the fluid container is squeezed.

27. The applicator of claim 24 , comprising a spray-type lubricant container securely mechanically coupled to the container interface, wherein fluid within the spray-type lubricant container is fluidly coupled to the fluid conduit.

28. The applicator of claim 1 , comprising a fluid container securely mechanically coupled to the container interface.

29. The applicator of claim 1 , wherein the container interface comprises a flip-top spout dispenser.

30. The applicator of claim 1 , wherein the container interface comprises a spout configured to securely mechanically couple to a flexible tube.

31. The applicator of claim 1 , wherein the body comprises a rib on both sides of the cavity in a transverse direction and configured to retain the fluid transfer pad.

32. The applicator of claim 31 , wherein each rib is characterized by a height that is less than a thickness of the fluid transfer pad.

33. The applicator of claim 1 , comprising a chain guide, wherein the chain guide comprises at least one guide rib on either side of the cavity, wherein each guide rib extends beyond a thickness of the fluid transfer pad.
