Cup holders such as handles made by injection molding of plastic are used in part on the assumption that they will be used repeatedly, but they are not widely used because they require time and effort to clean after use and there are management problems. In addition, a simple-type coffee dripper and a thin plastic cup, as well as a plastic molded disposable cup holder were partly put to practical use, but the cost was high and the waste after use was bulky. There was also a problem in terms of volume reduction.

[0003] On the other hand, canned beverages are often consumed by consumers at places other than homes, such as in resort areas, and at retail stores, convenience stores (CVS), and vending machines.
Depending on the type of beverage, so that you can drink delicious immediately,
It has become common practice to use a stocker for heating or cooling to adjust the temperature to the point of drinking before selling. In such a case, it is particularly preferable to heat coffee, tea, etc. to a relatively high temperature, but if heated to such a temperature, the can has good thermal conductivity, so it is too hot and bare hands. I can't drink it while holding it. Therefore, under the present circumstances, although the heating temperature is kept at a constant level to be heated and sold, consumers still demand some kind of heat insulation measures such as a heat insulation holder. In order to meet such a demand, a heat insulating can holder for coffee or tea has been studied and proposed for retail stores and CVS.
It has not yet spread due to problems such as appearance, labor of wearing, and price.
