Abstract

A mouthwash dispensing system including: a bottle with a threaded neck (150) defining an opening (140) and configured to hold a liquid; a dispenser (340) including a receiving orifice (380) and a receiving protrusion (390); and a spring-actuated adapter, including: an adapter orifice (250); a valve stem (220, 260) including a spring (270) and a seal (280), wherein the spring (270) is configured to bias the seal (280) to move the spring-actuated adapter to a closed position; a threaded adapter (230) configured to couple the spring-actuated adapter to the threaded neck (150); and a friction-fit adapter configured to couple the spring-actuated adapter to the dispenser (340); wherein, when the spring-actuated adapter is coupled to the dispenser (340), the receiving protrusion (390) moves the spring-actuated adapter to an open position to allow the liquid to flow from the bottle through the adapter orifice (250) and into the dispenser (340).

First claim

What is claimed is:

1. A dispensing system, comprising:
a bottle, the bottle comprising a threaded neck defining an opening and configured to hold a liquid;
a dispenser comprising a receiving orifice and a receiving protrusion; and
a spring-actuated adapter, comprising:
an adapter orifice;
a valve stem configured to hold a spring and a seal, wherein the spring is configured to bias the seal to move the spring-actuated adapter to a closed position;
a threaded adapter configured to couple the spring-actuated adapter to the threaded neck; and
a form-fit adapter configured to couple the spring-actuated adapter to the dispenser;

wherein, when the spring-actuated adapter is coupled to the dispenser, the receiving protrusion moves the spring-actuated adapter to an open position to allow the liquid to flow from the bottle through the adapter orifice and into the dispenser;
wherein the spring-actuated adapter further comprises a rim defining the adapter orifice; and
wherein the spring is disposed around an exterior wall of the valve stem, and
wherein, when the spring-actuated adapter is coupled to the dispenser, an end of the exterior wall contacts a bottom surface of the rim to protect the spring from contact with the liquid flowing through the spring-actuated adapter.

2. The dispensing system of claim 1 ,
wherein, in the open position, the receiving protrusion is configured to push the valve stem to move the seal away from the adapter orifice.

3. The dispensing system of claim 2 ,
wherein the receiving protrusion is configured to push the valve stem a sufficient distance to displace the seal from the adapter orifice in the open position.

4. The dispensing system of claim 3 , wherein the valve stem comprises one or more outlets, and
wherein, when the spring-actuated adapter is coupled to the dispenser, the receiving protrusion pushes the valve stem a sufficient distance to fluidly connect at least a portion of the one or more outlets to an interior of the bottle.

5. The dispensing system of claim 4 , wherein the seal is coupled to a top surface of the valve stem, and
wherein the top surface of the valve stem and at least a portion of the one or more outlets are fluidly connected to the receiving orifice when the spring-actuated adapter is coupled to the dispenser.

6. The dispensing system of claim 1 , wherein the threaded adapter comprises a threaded channel that receives the threaded neck.

7. The dispensing system of claim 6 , wherein the threaded neck comprises a continuous thread configured to couple to a continuous thread screw cap, and
wherein the threaded channel comprises a continuous thread configured to couple to the continuous thread of the threaded neck.

8. The dispensing system of claim 6 , wherein the threaded neck comprises a non-continuous thread configured to couple to a child-proof type cap, and
wherein the threaded channel comprises a complementary non-continuous thread configured to couple to the non-continuous thread of the threaded neck.

9. The dispensing system of claim 1 , wherein the liquid is an oral care product.

10. The dispensing system of claim 9 , wherein the bottle is a mouthwash bottle and the liquid is a mouthwash.

11. A spring-actuated adapter for a liquid dispenser, comprising:
an adapter orifice;
a valve stem configured to hold a spring and a seal, wherein the spring is configured to bias the spring-actuated adapter into a closed position;
a threaded adapter configured to couple the spring-actuated adapter to a bottle; and
a form-fit adapter configured to couple the spring-actuated adapter to a liquid dispenser;
wherein, when the spring-actuated adapter is coupled to the liquid dispenser, the spring-actuated adapter is placed in an open position;
wherein the spring-actuated adapter further comprises a rim defining the adapter orifice;
wherein the spring is disposed around an exterior wall of the valve stem, and
wherein, when the spring-actuated adapter is coupled to the liquid dispenser, an end of the exterior wall contacts the rim to protect the spring from contact with liquid flowing through the spring-actuated adapter.

12. The spring-actuated adapter of claim 11 , wherein the seal is configured to seal the adapter orifice and wherein, in the closed position, the spring biases the seal against the adapter orifice.

13. The spring-actuated adapter of claim 11 , wherein, in the open position, a receiving protrusion of the dispenser pushes on the valve stem and moves the seal away from the adapter orifice, which opens the adapter orifice to allow the liquid to flow from the bottle through the adapter orifice of the spring-actuated adapter and into the dispenser.

14. The spring-actuated adapter of claim 11 , wherein the threaded adapter comprises a threaded channel that receives a threaded neck of the bottle.

15. The spring-actuated adapter of claim 11 , wherein the liquid is a mouthwash.
