1. A package, comprising: a container having a first color comprising an open top, a closed bottom, and a body portion;a flexible overcap configured to be removeably attached to the container and configured to be pressed down on to force air out of the container on a regular basis wherein at least part of the flexible overcap is made of a translucent thermoplastic elastomer;a gasket having a second color that is different from the first color comprising a translucent, thermoplastic elastomer residing between the container and the overcap, wherein contact between the gasket and the container creates a color changing seal having the second color, andwherein the color changing seal changes to a third color that is different from the first color and the second color when a negative pressure differential exists between the inside of the package and the outside of the package;a closure removeably attached to the container and including a one-way valve;a visual indicator disposed on and integral with the flexible overcap;wherein the visual indicator includes a) a bubble portion that is concave outwardly to the interior of the container, wherein the bubble portion is at least partially concave inwardly to the interior of the container when a negative pressure differential exists between the inside of the package and the outside of the package, andwherein the bubble portion does not overlap with the center of the flexible overcap,b) a bump portion residing on the bubble portion, andan outer ring portion encompassing the bubble portion. 2. The package of claim 1 and wherein the overcap is made from a plastic material selected from the group consisting of polycarbonate, low density polyethylene, high density polyethylene, polyethylene terephthalate, polypropylene, polystyrene, polyvinyl chloride, co-polymers thereof, and combinations thereof. 3. The package of claim 1 and wherein the closure comprises a laminated peelable seal. 4. The package of claim 1 and the visual indicator comprises a thermoplastic elastomer. 5. The package of claim 1 and further comprising roast and ground coffee within the container. 6. The package of claim 1, wherein the first color is yellow and the second color is blue and the third color is green. 7. A package comprising: a container having a first color comprising an open top, a closed bottom, and a body portion;a flexible overcap having a center, configured to be removeably attached to the container and configured to be pressed down on to force air out of the container on a regular basis wherein at least part of the flexible overcap is made of a translucent thermoplastic elastomer;a gasket having a second color that is different from the first color comprising a translucent, thermoplastic elastomer residing between the container and the overcap, wherein contact between the gasket and the container creates a color changing seal having the second color, andwherein the color changing seal changes to a third color that is different from the first color and the second color when a vacuum exists inside the container;a closure removeably attached to the container and including a one-way valve;a visual indicator disposed on and integral with the flexible overcap, wherein the visual indicator includes a) a bubble portion, wherein the bubble portion of the visual indicator does not overlap with the center of the flexible overcap,b) a bump portion residing on the bubble portion, andc) an outer ring portion encompassing the bubble portion;wherein the visual indicator has a first position and a second position, the first position comprising at least one of the bump portion and the bubble portion concave outwardly from the interior of the container, the second position comprising at least one of the bump portion and the bubble portion concave inwardly towards the interior of the container; andwherein the visual indicator assumes the second position when a vacuum exists inside the container. 8. The package of claim 7 and wherein an air tight seal is formed between the container and the overcap. 9. The package of claim 7, wherein the first color is yellow and the second color is blue and the third color is green.
