Abstract

A dispensing system including a cap that is capable of securing the dispensing system to a bottle filled with a formula, wherein the cap is configured to retain a metered dose of the formula, a shaft in fluid communication with the cap, an accordion bladder inside the cap, wherein the accordion bladder includes at least one opening, one or more bellows, and a stopper, a distributor nozzle in fluid communication with the shaft, and an outer nozzle covering the distributor nozzle and configured to dispense the formula.

First claim

The invention claimed is:

1. A dispensing system comprising:
a cap configured to secure the dispensing system to a bottle filled with a formula, wherein the cap is configured to retain a metered dose of the formula;
a shaft in fluid communication with the cap;
an accordion bladder inside the cap, wherein the accordion bladder comprises at least one opening, one or more bellows, and a stopper, wherein the stopper is configured to lift when the bottle is compressed, thereby blocking the shaft;
a distributor nozzle in fluid communication with the shaft; and
an outer nozzle covering the distributor nozzle and configured to dispense the formula.

2. The dispensing system of claim 1 , wherein the cap further comprises at least two tabs to secure the cap to the bottle.

3. The dispensing system of claim 1 , wherein the at least one opening is located on a base of the accordion bladder.

4. The dispensing system of claim 1 , wherein an angle between 1°-89° is formed between the one or more bellows when the accordion bladder is not compressed.

5. The dispensing system of claim 1 , wherein the formula is a hair product.

6. The dispensing system of claim 1 , wherein the dispensing system further comprises an actuator configured to put the dispensing system into an active or inactive state.

7. The dispensing system of claim 6 , wherein twisting the actuator in one direction puts the dispensing system into an active state.

8. The dispensing system of claim 7 , wherein twisting the actuator in a direction opposite to the one direction puts the dispensing system into an inactive state.

9. The dispensing system of claim 1 , wherein the accordion bladder further comprises an attachment, wherein the attachment is configured to secure the accordion bladder to the cap.

10. The dispensing system of claim 9 , wherein the attachment is configured to remain stationary when the accordion bladder compresses to block the shaft with the stopper.
