Abstract: An insulation container includes a flexible exterior container and a rigid interior container for maintaining stored items at a cool temperature. The exterior housing includes a lid for selectively sealing the entire open top thereof for selectively inserting or removing large or multiple items, the lid having an auxiliary door for quickly removing small or single items from the internal storage area. Opening only the auxiliary door also helps to maintain the internal temperature for a longer time than is possible if the entire lid is opened. The interior housing may be constructed of stainless steel for enhanced insulation with an intermediate housing sandwiched between interior and exterior housings. The intermediate housing may include a rubber material for preventing condensation from forming on the exterior housing.

Abstract: An insole according to the present invention includes an upper layer defining at least one well containing a chemical indicator that gradually changes colors upon exposure to salt or sulfur. The insole includes a lower layer connected to the upper layer that includes an adhesive for stacking multiple insoles together in packaging and for holding the insole in place in a shoe. The insole includes an absorbent material for absorbing perspiration. Perspiration produces salt and bacterial and fungal degradation of keratin skin cells produces sulfur, leading to foot odor. The insole includes fungicide and deodorant for controlling this odor and the color change of the chemical in the well provides a visual indication of when a new insole (with it fungicide and deodorant) needs to be replenished through replacement.
