Cup Insulation Discussion of Patents

All of these patents are highly interrelated in function and design. The eldest of the patents is the thermal coffee cup. This coffee cup was patented in 1948 with just one claim. The claim is quite short in comparison to the others because it is a basic first version of the thermal cup which details the design of the cup and how it maintains heat. Next, we have the patent for the sleeve construction for improved paperboard cup insulation. This invention details the need for a sleeve around the container of the beverage and how it will work with the grooves in the sleeve to tightly grip the cup as to not fall off while also insinuating how it is to be constructed. The third oldest priority date goes to the insulating sleeve. Insulating sleeves are used specifically for hot beverages as explained in the patent and includes detailed art about how the sleeve grabs onto the sidewall of the cup and protects the user from the heat of the drink. Next on the list is the insulator sleeve for a beverage container which seems oddly similar to the first except that it takes the first inventions and adds on more layers. Technical designs show the dynamics of the sleeve itself and gets down to the dimensions of it all. Our next up is the beverage cup sleeving system and method. Basically, this patent is all about how the sleeving should be done and exactly the system and methodology behind it. The protective sleeve is next where it goes into detail about a protective sleeve around a beverage which might not necessarily be to protect against hot beverages or not. Second to last, we have the temperature indicating sleeve and related container which is about a sleeve that indicates the temperature so it takes the original hot sleeve and improves upon that by adding the indicator. Finally, we have the Hot and Cold Cup Sleeve which can be seen as yet another one upping of the old fashioned sleeve where this not only protects from hot but also the cold, it was recently filed in 2014 which seems remarkable that it was not done sooner.
