Abstract

Embodiments of the invention related to dispensing devices ( 100 ), and more particularly to dispensing devices having a dropper or dispenser ( 200 ) associated with a container ( 900 ) full of product wherein the dropper ( 200 ) may be charged, separated from the container ( 900 ), and then used to dispense a product therefrom.

Claims (62)

1. A dispensing system, comprising:

a container;

a collar attached to the container, wherein the collar comprises:

a closure seated in an opening of the container;

a cap seated over the closure; and

a spring seated between the closure and the cap; and

a dropper configured for attachment to and separation from the collar, the dropper comprising:

a dropper base;

a tube attached to the dropper base; and

an actuator.

2. The dispensing system of claim 1 ,

wherein the closure comprises:

a cylindrical wall defining an outer circumference of the closure;

a cup positioned on an interior of the cylindrical wall; and

a bridge connecting the cylindrical wall and the cup;

wherein the cap comprises:

an upper portion,

an opening in the upper portion;

a cylindrical body portion extending off of an underside of the upper portion; and

an outer cylindrical body portion extending off of an underside of the upper portion,

wherein the diameter of the outer cylindrical body portion is greater than a diameter of the cylindrical body portion; and

wherein the spring engages an underside of the cap and an upper side of the closure.

3. The dispensing system of claim 2 , wherein the cylindrical wall further comprises threading on an internal surface of the cylindrical wall.

4. The dispensing system of claim 2 , wherein the cup further comprises an opening in a central portion of the cup.

5. The dispensing system of claim 4 , wherein the tube fits through the opening in the upper portion of the cap and the opening in the central portion of the cup when the dropper is engaged with the collar.

6. The dispensing system of claim 5 , wherein the opening in the upper portion of the cap engages the tube as the dropper is separated from the collar.

7. A dispensing system, comprising:

a container;

a piston follower seated in an interior of the container;

a cup connector fixed to the container and comprising a valve seat;

a valve seated in the valve seat, and

a dropper removeably attached to the cup connector, wherein the dropper comprises a dropper base and a tube attached to the dropper base, and wherein the tube is in contact with the valve when the dropper is affixed to the cup connector.

8. The dispensing system of claim 7 , wherein the dropper further comprises:

a first opening in the dropper base;

a tube connection extending off a bottom surface of the dropper base around the first opening, an accumulator seated on an upper surface of the dropper base and surrounding the first opening;

a second opening in the accumulator opposite the first opening in the dropper base;

a piston seated in an interior space of the accumulator,

a piston stem attached to the piston and extending through the second opening;

an actuator attached to the piston stern;

a spring seated between the actuator and the accumulator; and

wherein the tube is attached to the tube connection.

9. A dispensing system, comprising:

a container;

a collar attached to an opening in the container, comprising a valve seat;

a valve seated in the valve seat;

a container piston seated about a portion of the collar; and

a dropper removeably attached to the collar, wherein the dropper comprises:

a dropper base,

a first opening in the dropper base;

a tube connection extending off a bottom surface of the dropper base around the first opening;

an accumulator seated on an upper surface of the dropper base and surrounding the first opening; a second opening in the accumulator opposite the first opening in the dropper base;

a piston seated in an interior space of the accumulator;

a piston stem attached to the piston and extending through the second opening;

an actuator attached to the piston stem;

a spring seated between the actuator and the accumulator; and

a tube attached to the tube connection.

10. The dispensing system of claim 9 , wherein the collar further comprises:

a collar base;

an opening in the collar base,

a cylindrical wall extending away from the collar base in a first direction;

a tube sleeve extending away from the collar base in a direction opposite the cylindrical wall, the tube sleeve encompassing the opening in the collar base, wherein the valve seat is at an end of the tube sleeve opposite the opening in the collar base; and

wherein the container piston is seated on an exterior surface of the tube sleeve.
