Our business Yowsr wants to offer, amongst other products, lifetime warranty bottles, mugs, tumblers, food containers with the highest heat / cold retention rates in the market. Typically these qualities are a result of using 2 stainless steel walls with a vacuum in between. We need a solution that beats the competitors by at least 12 hours of heat or cold retention, while keeping the weight to an acceptable limit. Since these products will have lifetime warranty they have to be indestructible or contain certain parts like rubber rings that are easily replaceable.
Examples are Stanley and Yeti, but we need to find a way to offer far superior heat/cold retention.
So how can we limit loss of heat transfer more than what has been achieved so far.
