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 ### Claim at position 1 1-14. (canceled) ### Claim 15 A mixing and dispensing apparatus, comprising: a first container that includes a main body portion, a first opening, and a second opening, the main body portion being configured to retain a first substance; a second container configured to retain a second substance, the second container being compressible and having a spout in fluid communication with the main body portion of the first container through the second opening; and a plunger received entirely within the second container, the plunger being aligned with the spout and configured to open the spout when the second container is compressed to release the second substance into the main body portion of the first container. ### Claim 16 (depends on 15) The apparatus of claim 15, wherein the first container is configured to dispense the first substance or a combination of the first substance and the second substance through the first opening. ### Claim 17 (depends on 15) The apparatus of claim 15, wherein the first container further includes a receiving portion coupled to the main body portion, the receiving portion including a compartment that is configured to receive the second container. ### Claim 18 (depends on 17) The apparatus of claim 17, wherein the receiving portion is configured to be integrally molded with the main body portion. ### Claim 19 (depends on 17) The apparatus of claim 17, wherein the receiving portion further includes a neck extending between the main body portion and the second container such that the second container is in fluid communication with the main body portion. ### Claim 20 (depends on 19) The apparatus of claim 19, wherein the neck includes a ramp connected to a bottom of the main body portion at an angle greater than or equal to 30 degrees and less than or equal to 45 degrees. ### Claim 21 (depends on 19) The apparatus of claim 19, wherein the main body portion has a first width, the compartment has a second width, and the neck has a third width and wherein the first width and the second width are greater than the third width. ### Claim 22 (depends on 17) The apparatus of claim 17, wherein the main body portion has a first width and the compartment has a second width and wherein the first width and the second width are substantially equal. ### Claim 23 (depends on 17) The apparatus of claim 17, wherein: the compartment includes a top and a bottom portion; and a compartment opening through which the second container is received is located at the top. ### Claim 24 (depends on 23) The apparatus of claim 23, wherein the compartment opening is threaded to receive a cover. ### Claim 25 (depends on 17) The apparatus of claim 17, wherein the compartment is configured to extend to one side of the main body portion. ### Claim 26 (depends on 25) The apparatus of claim 25, wherein the compartment includes a first side that is substantially parallel to a side of the main body portion. ### Claim 27 (depends on 25) The apparatus of claim 25, wherein the compartment includes a first side that is attached to a side of the main body portion by an elongated web member to support the compartment against movement. ### Claim 28 A mixing and dispensing apparatus, comprising: a first container that includes a main body portion configured to retain a first substance and a receiving portion coupled to the main body portion, the receiving portion including a compartment configured to receive a second container, wherein the second container is configured to retain a second substance, the second container being compressible and having a spout in fluid communication with the main body portion of the first container through the second opening; and a plunger received entirely within the second container, the plunger being aligned with the spout and configured to open the spout when the second container is compressed to release the second substance into the main body portion of the first container. ### Claim 29 (depends on 28) The apparatus of claim 28, wherein the receiving portion is configured to be integrally molded with the main body portion. ### Claim 30 (depends on 28) The apparatus of claim 28, wherein the compartment includes a top and a bottom portion; and a compartment opening through which the second container is received is located at the top. ### Claim 31 (depends on 28) The apparatus of claim 28, wherein the compartment is configured to extend to one side of the main body portion. ### Claim 32 (depends on 31) The apparatus of claim 31, wherein the compartment includes a first side that is attached to a side of the main body portion by an elongated web member. ### Claim 33 A method of mixing a dispensing a sterilized composition within a cleanroom, comprising: providing an apparatus including: a first container including a main body portion and a receiving portion that includes a compartment configured to receive a second container that has a spout extending through a passageway in the compartment and in fluid communication with the main body portion; and a plunger received entirely within the second container; filling at least a portion of the main body portion of the first container with a first substance; filling at least a portion of the second container with a second substance; aligning the plunger with the spout; applying downward pressure to the plunger such that the plunger opens the spout to release the second substance into the main body portion such that the first and second substances mix. ### Claim 34 (depends on 33) The method of claim 33, wherein the first substance is sterile water and the second substance is a concentrated cleaner.
