Abstract

The device comprises a flexible, expandable hose which has a coupling at one end for mating with the toner hopper of either of a photocopy machine or a computer print-out machine, the other end of the hose having a coupling for mating with the neck of the toner canister so that toner may be loaded from the canister into the hose from outside of the machine which uses the toner, the toner canister is then removed from attachment to the hose, the hose is capped and the hose is compressed, whereby the toner is loaded into the machine with minimal spillage.

Claims

1. A method of loading toner from a canister into a machine of the type having a toner hopper, the method comprising the steps of:

removably connecting one end of an expandable hose to the machine to empty into the hopper,

removably connecting the other end of the hose to the toner canister;

stretching the hose from the machine while simultaneously emptying the canister into the hose,

detaching the canister from the hose,

closing off the hose end which has been detached from the canister, and

compressing the hose in the direction of its length while simultaneously emptying the bulk of the toner within the hose into the hopper.

2. The method as recited in claim 1 wherein the step of connecting the end of the hose to the toner canister comprises the step of:

threading the canister into the open end of the hose with the canister held with its open end vertically upright so that no toner leaves the canister during the coupling step.

3. The method as recited in claim 1 wherein the machine has a threaded female socket, the hose has a matching threaded male coupling, the toner canister is a bottle having a threaded neck and the hose has a matching female threaded coupling and wherein the step of attaching the hose to the machine comprises the step of screwing the hose end into the hopper female socket and attaching the canister to the hose comprises the step of threading the canister neck into the female coupling of the hose.

4. In combination with a toner canister and a machine having a toner hopper apparatus for loading toner from the canister into the machine, the apparatus comprising

an expandable hose,

means for removably connecting one end of the expandable hose to the machine to empty the hose contents into the hopper,

means for removably connecting the other end of the hose to the toner canister, and

means for closing off the other hose end when detached from the canister.

5. The combination as recited in claim 4 wherein the means for connecting the end of the hose to the toner canister comprises

corresponding male and female threaded couplings on the other end of the hose and the canister for threadably connecting the canister into the open end of the hose with the canister held with its open end vertically upright so that no toner leaves the canister during the coupling step.

6. The combination as recited in claims 4 or 5 wherein the machine has a threaded female socket, the hose has a matching threaded male coupling, the toner canister is a bottle having a threaded neck and the hose has a matching female threaded coupling whereby the hose can be attached to the machine by screwing the hose end into the hopper female socket and the canister can be attached to the hose by threading the canister neck into the female coupling of the hose.
