1. A container for a perishable product comprising: a vial configured to hold the perishable product;a lid, removably coupled to the vial, and having an inner surface configured to contact the vial, and a top surface opposite the inner surface; anda temperature condition indicator comprising a threshold temperature conditional indicator, disposed upon the top surface;wherein the temperature condition indicator comprises: a cup;a liquid formulation, contained in the cup, that will irreversibly change appearance when exposed to a temperature condition; anda cover, disposed over the cup, wherein the cover is sufficiently transparent that a change in appearance of the liquid formulation that results from exposure to the temperature condition is detectable through the cover;wherein the liquid formulation is visible through the cover before the temperature condition occurs; andwherein the cup, liquid formulation, and cover are configured and assembled to minimize the presence of bubbles in the liquid formulation. 2. The container of claim 1, wherein the temperature condition indicator comprises water and a hydrophobic material, a colorant, or a reactive agent that changes color upon reaction. 3. The container of claim 1, wherein the cup has a volume of about 1 μL to about 150 μL. 4. The container of claim 1, wherein the cover has a viewing area of about 0.5 mm2 to about 80 mm2. 5. The container of claim 1, wherein the cup has a depth of about 0.1 mm to about 2 mm. 6. A vial for a perishable product comprising: a temperature condition indicator comprising a threshold temperature condition indicator, the temperature condition indicator comprising:a cup;a liquid formulation, contained in the cup, that will irreversibly change appearance when exposed to a temperature condition; anda cover, disposed over the cup, wherein the cover is sufficiently transparent that a change in appearance of the liquid formulation that results from exposure to the temperature condition is detectable through the cover;wherein the liquid formulation is visible through the cover before the temperature condition occurs; andwherein the cup, liquid formulation, and cover are configured and assembled to minimize the presence of bubbles in the liquid formulation; andwherein the temperature condition indicator is located on a lid of the vial, on a label affixed to the vial, or on a bottom surface of the vial. 7. The vial of claim 6, wherein the liquid formulation is a freeze indicator formulation. 8. The vial of claim 7, wherein the lid has a clear covering to allow viewing of the freeze indicator formulation. 9. The vial of claim 6, wherein a freeze indicator formulation is contained within a self-adhesive indicator affixed to the lid, a vial body or the bottom of the vial. 10. The vial of claim 6, wherein the label is attached to the lid, a vial body, or the bottom. 11. The vial of claim 10, wherein the label is a flexible blister having a volume that is about 5 microliters or less than 5 microliters. 12. The vial of claim 6, wherein the temperature condition indicator is a binary indicator. 13. The vial of claim 6, wherein the temperature condition indicator is not a binary indicator, so that quantitative damage to a product in the vial can be detected. 14. The vial of claim 6, wherein the temperature condition indicator indicates a temperature condition at about or below the freezing temperature of a solution contained in the vial. 15. The vial of claim 6, wherein the temperature condition indicator indicates a temperature condition at about or above the freezing temperature of a solution contained in the vial. 16. The vial of claim 6, wherein an additional temperature condition indicator is included unattached to the vial so that the additional temperature condition indicator can be applied in the event that the temperature condition indicator of the lid, label, or bottom is removed. 17. The vial of claim 6, wherein the temperature condition indicator undergoes a change in color to denote a temperature condition. 18. The vial of claim 6, wherein the temperature condition is not detected by a change in color of the temperature condition indicator. 19. The vial of claim 6, wherein the temperature condition indicator comprises a liquid media, a gel media, a solid state media, a mixture of a liquid and a gel media, a mixture of a gel and a solid state media, or a mixture of a liquid and a solid state media.
