Abstract

Tape dispensers with an improved wetting system are disclosed. The tape dispensers include a holder for a roll of liquid-activatable tape, a wetting system that has a reservoir of liquid and a roller having an absorbable outer surface to absorb and dispense liquid, and a manually operated feeding mechanism. The roller is at least partially immersed in the reservoir of liquid and the wetting system includes a roller adjustment mechanism to simultaneously adjust an upward force applied by the roller to the liquid activated tape and an immersion depth of the roller into the reservoir of liquid. The wetting system may also include a pressure mechanism to adjust a downward force applied to the liquid activated tape as it passes over the roller.

First claim

What is claimed is:

1. A manually operated tape dispenser comprising:
a holder for a roll of liquid-activatable tape;
a wetting system comprising:
a reservoir of liquid
a roller at least partially immersed in the reservoir of liquid, wherein the roller is an open cell foam roller having an absorbable outer surface that allows liquid to absorb into and dispense from the open cell foam, the absorbable outer surface having a cell structure different than an underlying structure of the open cell foam; and
a manually operated feeding mechanism comprising a pressure mechanism to adjust a downward force applied to the liquid activated tape as it passes over the roller.

2. The manually operated tape dispenser of claim 1 , wherein the absorbable outer surface of the roller includes a plurality of closed pore features for controlled disbursement of the liquid from the roller.

3. The manually operated tape dispenser of claim 1 , wherein the open cell foam comprises one or more of an acrylic material, a nylon material, and a cellulose material.

4. The manually operated tape dispenser of claim 1 , wherein the wetting roller includes the open cell foam adhered to a shaft.

5. The manually operated tape dispenser of claim 1 , wherein the pressure mechanism comprises a pressure plate.

6. The manually operated tape dispenser of claim 5 , wherein the roller adjustment mechanism includes a vessel having one or more adjustment screws to change the height of the wetting roller relative to the vessel.

7. The manually operated tape dispenser of claim 6 , wherein the pressure mechanism comprises a pressure plate, and the vessel has a mount for the pressure plate.

8. The manually operated tape dispenser of claim 6 , wherein the vessel includes a left notch and a right notch each having therein one of the adjustment screws.

9. The manually operated tape dispenser of claim 6 , wherein the vessel has a deep well portion comprising a mount for the wetting roller and a shallow well portion in fluid communication with the deep well portion.

10. The manually operated tape dispenser of claim 9 , further comprising a liquid reservoir for filling the vessel, the liquid reservoir having an outlet valve, wherein the shallow well portion includes a post and the post is received in the outlet valve of the liquid reservoir.

11. The manually operated tape dispenser of claim 10 , wherein the shallow well portion includes a water level adjustment screw in contact with the liquid reservoir.

12. The manually operated tape dispenser of claim 1 , further comprising a roller adjustment mechanism configured to simultaneously adjust an upward force applied by the roller urging the roller into contact with the liquid activated tape and an immersion depth of the roller in the reservoir of liquid.

13. The manually operated tape dispenser of claim 1 , further comprising a vessel housing additional liquid in fluid communication with the reservoir.

14. The manually operated tape dispenser of claim 1 , wherein the tape dispenser is a free-standing machine or a table top machine.

15. The manually operated tape dispenser of claim 14 , wherein the free-standing machine or the table top machine includes a housing defining a storage position for the holder for the roll of liquid activated tape.
