Abstract

A mixing and dispensing apparatus having first and second containers. The first container has a main body portion which retains a first substance. A separate compartment is located in the first container and an internal passageway is formed between the main body portion and the compartment. The second container is configured to retain a second substance, and is compressible. The second container has a top end and a closed spout, wherein the closed spout is located in the compartment with the spout extending through the internal passageway into the main body portion of said first container. A release mechanism is formed by a plunger extending within the second container. The plunger has a first end in communication with the top end of the second container, and a second end aligned with the closed spout. The second end opens the closed spout when the second container is compressed to release the second substance into the main body portion of the first container.

Claims

1. A mixing and dispensing apparatus comprising:

a first container having a main body portion retaining a first substance and a compartment with an internal passageway between the main body portion and the compartment;

a second container configured to retain a second substance, said second container being compressible and having a top end and a closed spout, wherein the closed spout is located in said compartment with the spout extending through the internal passageway into the main body portion of said first container; and

,

a plunger extending within said second container and having a first end in communication with the top end of said second container, and a second end aligned with the closed spout, whereby the second end opens the closed spout when said second container is compressed to release the second substance into the main body portion of said first container.

2. The apparatus of claim 1, wherein said apparatus is configured for use in a clean room.

3. The apparatus of claim 1, further comprising a foil positioned over the spout to close the spout.

4. The apparatus of claim 3, wherein the plunger pierces the foil to create an opening in the foil when the second container is compressed.

5. The apparatus of claim 1, further comprising a flexible barrier positioned in said compartment about said second container.

6. The apparatus of claim 1, further comprising:

an opening at the top end of said second container;

a cover for closing said opening, said cover having a central bore;

a head located at the first end of said plunger and received in the central bore of said cover; and

a retainer positioned about said head for retaining the plunger in the central bore of said cover.

7. The apparatus of claim 6, further comprising prongs at the second end of said plunger, said prongs piercing the closed spout.

8. The apparatus of claim 1, wherein said spout is offset on the main body portion of said second container.

9. The apparatus of claim 1, wherein said second container has a neck configured to be received in the passageway.

10. The apparatus of claim 9, further comprising a wide lip extending outward from said neck.

11. The apparatus of claim 10, wherein said passageway has a wide portion and a narrow portion, wherein the narrow portion is narrower than the wide lip, and wherein the spout neck and lip are received in the wide portion and moved into the narrow portion such that the wide lip is on a far side of the passageway.

12. The apparatus of claim 1, wherein said compartment is separate and apart from said main body portion, and further comprising a neck connecting said compartment to said main body portion.

13. The apparatus of claim 12, wherein said compartment is parallel with said main body portion.

14. The apparatus of claim 1, wherein said main body portion comprises a spray bottle.
