Abstract
Methods and apparatus for vacuum forming a beverage carrier yoke using a slurry. The slurry comprises: a moisture barrier comprising AKD in the range of about 4% by weight; and a fiber base comprising OCC and NP.
Claims14
A method of manufacturing a yoke configured to carry beverage cans, comprising:
- providing a wire mesh mold in the shape of the yoke;
- immersing the mold in a fiber-based slurry;
- drawing a vacuum across the wire mold to cause fiber particles to accumulate at the wire mesh surface;
- and
- removing the mold and attached fiber particles from the slurry;
- and
- subsequently drying the fiber particles to yield the yoke;
- wherein the slurry comprises a moisture barrier.
