Abstract

A method and apparatus for storing and dispensing a viscous product. The product and a propellant are stored in a container on a base, and the propellant forms a head space. In a storage configuration, the container rests on the base, the base rests on a surface, and the propellant in the head space and the product tend to move toward positions wherein the propellant in the head space is at a higher elevation than the product and the product is at a higher elevation than an inlet to a dispenser. In one aspect, the base comprises a first portion, a second portion comprising a lid, a sidewall comprising a window, and an interior. In a second aspect, the method comprises storing the container in the storage configuration, removing the lid to expose a dispenser, dispensing the product, and viewing an interior of the base through the window.

First claim

We claim:

1. An apparatus comprising:
a viscous product;
a propellant;
a container that contains the viscous product and the propellant, wherein the propellant forms a head space in the container, and
a base for the container;
wherein the container comprises a first portion and a second portion opposite the first portion of the container; wherein the second portion of the container comprises a dispenser;
wherein the base and the container are configured so that, when the base and the container are in a storage configuration, the second portion of the container is adjacent to the base, the container rests on the base, the base rests on a surface, and the viscous product and the propellant in the head space tend to move toward positions wherein the propellant in the head space is at a higher elevation than the viscous product and the viscous product is at a higher elevation than an inlet to the dispenser;
wherein the base comprises:
a first portion of the base, wherein the first portion of the base comprises a first end of the base;
a second portion of the base, wherein the second portion of the base comprises an integral second end of the base, and wherein the integral second end of the base is opposite the first end of the base;
a sidewall between the first end of the base and the integral second end of the base, wherein the sidewall comprises an interior surface of the sidewall;
an interior of the base, wherein the interior of the base comprises the interior surface of the sidewall and any point between two points on the interior surface of the sidewall;
a lid, wherein the lid is removable and wherein the lid comprises a safety mechanism to prevent actuation of the dispenser while the lid is engaged with the base and the dispenser; and
an actuator for the dispenser;

wherein the first end of the base comprises a first opening of the base; and
wherein the integral second end of the base comprises a second opening of the base.

2. The apparatus of claim 1 , wherein the sidewall comprises a window positioned to provide a line of sight from a point outside the base to the interior of the base.

3. The apparatus of claim 1 , wherein the first portion of the base is fixed to the second portion of the container and the second portion of the base is configured to extend away from the first portion of the base and past a dispensing tip of the dispenser.

4. The apparatus of claim 1 , wherein the sidewall comprises a window positioned to provide a line of sight from a point outside the base to the interior of the base.

5. The apparatus of claim 1 , wherein the apparatus comprises:
a transparent material positioned to provide a line of sight from a point outside the base to the interior of the base while the base is joined to the container.

6. The apparatus of claim 1 , wherein the second portion of the base comprises the lid.

7. The apparatus of claim 1 , wherein the dispenser comprises a valve for dispensing the viscous product; and wherein the actuator comprises an extension configured to be moved into contact with the dispenser, thereby actuating the valve to dispense the viscous product.

8. The apparatus of claim 1 , wherein the lid is a tamper-evident lid.

9. The apparatus of claim 1 , wherein the base is integral to the container.

10. The apparatus of claim 1 , wherein the base is removably fixed to the container.

11. The apparatus of claim 1 , wherein the first portion of the base is fixed to the second portion of the container; and wherein the second portion of the base is wider than the first portion of the base.

12. The apparatus of claim 11 , wherein the first portion of the base is removably fixed to the second portion of the container.

13. The apparatus of claim 12 , wherein the first portion of the base receives the second portion of the container through the first opening of the base.

14. The apparatus of claim 13 , wherein the first portion of the base comprises a lip.

15. The apparatus of claim 13 , wherein the integral second end of the base has a continuous cross-section.

16. A method for storing and dispensing a viscous product; wherein the viscous product and a propellant are stored in a container on a base; wherein the propellant forms a head space; wherein the container comprises a first portion and a second portion opposite the first portion of the container; wherein the second portion of the container comprises a dispenser; wherein the container is configured to dispense the viscous product when the propellant in the head space is at a higher elevation than the viscous product and the viscous product is at a higher elevation than an inlet to the dispenser; wherein the base comprises a first portion, a second portion opposite the first portion of the base, a sidewall, an interior of the base, a lid, and an actuator for the dispenser; wherein the first portion of the base comprises a first end of the base; wherein the second portion of the base comprises an integral second end of the base; wherein the integral second end of the base is opposite the first end of the base; wherein the sidewall is between the first end of the base and the integral second end of the base; wherein the sidewall comprises an interior surface of the sidewall; and wherein the interior of the base comprises the interior surface of the sidewall and any point between two points on the interior surface of the sidewall; said method comprising:
storing the container in a storage configuration on the base, wherein the container rests on the base, the base rests on a surface, and the viscous product and the propellant in the head space tend to move toward positions wherein the propellant in the head space is at a higher elevation than the viscous product and the viscous product is at a higher elevation than the inlet to the dispenser;
removing the lid from the base to expose the dispenser before dispensing the viscous product, wherein the lid comprises a safety mechanism to prevent actuation of the dispenser while the lid is engaged with the base and the dispenser; and
pressing the actuator on the base to actuate the dispenser and thereby dispense the viscous product.

17. The method of claim 16 , wherein the sidewall comprises a window positioned to provide a line of sight from a point outside the base to the interior of the base; and wherein the method comprises:
viewing the interior of the base through the window in the sidewall of the base.

18. The method of claim 16 , wherein the lid comprises a tamper evident seal; and wherein the method comprises:
moving the tamper evident seal into a configuration that indicates the container has been opened.

19. The method of claim 16 , wherein the method comprises:
cleaning the interior of the base.

20. The method of claim 17 , wherein the method comprises:
cleaning the interior of the base through the window in the sidewall of the base.

21. The method of claim 16 , wherein the method comprises:
cleaning the interior of the base through an opening in the second portion of the base.

22. The method of claim 16 , wherein the method comprises:
lighting the interior of the base through a light-passing portion of the base, wherein the light-passing portion of the base is selected from the group consisting of an opening, a transparent portion, and a translucent portion.

23. The method of claim 16 , wherein the method comprises:
applying the lid to the base after dispensing the viscous product.
