Methods for making a molded beverage container insulator from a slurry including water and a polysaccharide by presenting at least one male mold, which may have an elliptical cross section, therein and causing a portion of the slurry to temporarily adhere to the at least one mold. After a suitable period of time, removing the mold from the slurry and then removing the insulator. At such time, and particularly if the mold is not characterized as elliptical in cross section, the insulator is subject to bidirectional compression in order to collapse the same. Opposing hinge elements may be formed in the insulator, either at the time of molding or subsequently, to localize stresses resulting from the collapsing of the insulator. The resulting insulator is fully recyclable/compostable and possesses a constricting bias to mitigate container slip issues.
A method for making a beverage container insulator having an inside surface, an outside surface, a first end at a first opening, a second end at a second opening and a body portion between the first and second ends, wherein each opening is defined by a perimeter that joins the inside and outside surfaces, the method comprising:
