Abstract

A dispensing system includes a container containing a flowable base formulation to be dispensed, an additive mixing device, and an actuable pump engine which draws the flowable base formulation from the container and pumps it through the mixing device. The additive mixing device includes a body with an internal cavity, an additive ingredient within the cavity, and a flow path/mixing chamber between an input and an output. With each pump of the device the additive ingredient is introduced into, and mixed with, a flow of the base formulation traveling through the mixing device. Multiple additive mixing devices may be interchangeable for different formulations, and the mixing devices may be refillable.

First claim

What is claimed is:

1. A dispensing system comprising:
a container;
a flowable base formulation contained within the container;
a pump engine mounted on the container and in fluid communication with said base formulation;
a dispensing head having
a dispensing orifice,
a piston;
an additive ingredient chamber defined above said piston,
a base product chamber, configured and arranged to be filled with said base formulation, defined below said piston and having an inlet port in fluid communication with said pump engine,
a flow path from said additive ingredient chamber to said dispensing orifice,
a flow path from said base product chamber to said dispensing orifice; and

an additive ingredient contained within the additive ingredient chamber,
wherein the pump engine draws the flowable base formulation from the container and pumps it through the dispensing head, and wherein said additive ingredient is introduced into, and mixed with the base formulation traveling through the dispensing orifice with each actuation, and
wherein the pump engine and the dispensing head are coaxially spring biased.

2. The dispensing system of claim 1 wherein the dispensing head includes a removable cap over an opening into the additive ingredient chamber, wherein the additive ingredient chamber is refillable.

3. The dispensing system of claim 2 , wherein the dispensing head is removably mounted onto the pump engine.

4. The dispensing system of claim 1 , wherein the dispensing head is removably mounted onto the pump engine.

5. The dispensing system of claim 4 , wherein said inlet port includes a valve.

6. The dispensing system of claim 5 , wherein said dispensing orifice includes a valve.

7. The dispensing system of claim 4 , wherein said dispensing orifice includes a valve.

8. The dispensing system of claim 1 , wherein said inlet port includes a valve.

9. The dispensing system of claim 8 , wherein said dispensing orifice includes a valve.

10. The dispensing system of claim 9 , further comprising a removable cover having a sealing pin, said removable cover being selectively disposed on said dispensing head with said sealing pin engaged within said dispensing orifice.

11. The dispensing system of claim 8 , further comprising a removable cover having a sealing pin, said removable cover being selectively disposed on said dispensing head with said sealing pin engaged within said dispensing orifice.

12. The dispensing system of claim 1 , wherein said dispensing orifice includes a valve.

13. The dispensing system of claim 12 , further comprising a removable cover having a sealing pin, said removable cover being selectively disposed on said dispensing head with said sealing pin engaged within said dispensing orifice.

14. A dispensing system comprising:
a container;
a flowable base formulation contained within the container;
a pump engine mounted on the container and in fluid communication with said base formulation;
a dispensing head having
a dispensing orifice,
a piston;
an additive ingredient chamber defined above said piston,
a base product chamber, configured and arranged to be filled with said base formulation, defined below said piston and having an inlet port in fluid communication with said pump engine,
a flow path from said additive ingredient chamber to said dispensing orifice,
a flow path from said base product chamber to said dispensing orifice;

an additive ingredient contained within the additive ingredient chamber; and
a removable cover having a sealing pin, said removable cover being selectively disposed on said dispensing head with said sealing pin engaged within said dispensing orifice,
wherein the pump engine draws the flowable base formulation from the container and pumps it through the dispensing head, and wherein said additive ingredient is introduced into, and mixed with the base formulation traveling through the dispensing orifice with each actuation.
