  • a secondary insulating material (not shown) can surround the container to further increase the ability of the container to maintain refrigerating temperatures for longer periods of time and can limit condensation on the exterior of the container.
  • the secondary insulating material can, for example, be in the form of a secondary container such as a MYLAR bag, cardboard or an insulated, optionally foamed, plastic container that surrounds the reusable container.
  • ROXUL mineral wool insulation available from Roxul, Inc., which comprises 94-99% mineral fiber bound using a cured urea extended phenolic formaldehyde binder (1-6%) can be used as the secondary insulating material.
  • the mineral wool insulation can be provided as an insulated blanket that is customized to cover all the side of the container 10 and then the covered container can be placed in corrugated cardboard case for storage or transport. Although able to maintain a refrigerating or freezing temperature, the reusable container can, in some embodiments, still be heated to temperatures exceeding 100° F. without damage to the container or slurry.
  • the reusable container can be produced by various methods.
  • the container can be formed in a mold such as a rotational mold (rotomold) by providing the plastic material as a powder, heating the powder to allow it to flow within the mold, and casting the mold. Holes provided in the container to provide the slurry composition can be sealed using a sonic spin weld.
  • a method of shipping a product to be refrigerated in a reusable container comprises refrigerating a reusable container as described above.
  • the reusable container can be provided in a standing refrigerator or freezer to provide the desired initial temperature.
  • the container can be refrigerated at a temperature of ⁇ 30 to 41° F., with temperatures greater than 32° F. typically used for products to be stored at refrigerating temperatures and less than 32° F. used for products to be stored at freezing temperatures.
  • a product to be refrigerated or frozen can be inserted in the reusable container and then stored in the reusable container until it can be used or consumed.
  • the product can be kept in the container in a refrigerating or freezing environment for the periods of time discussed above.
  • certain parameters in the container can be modified. For example, the number of wall, top or bottom spaces and how many of these spaces include slurry can affect the level of refrigeration for the container (at a refrigerating or freezing temperature). The percentage of the total space occupied by the slurry can also affect the level of refrigeration.
  • the container materials selected, the inner wall thicknesses, the outer wall thicknesses, the wall space widths, the slurry composition and the slurry viscosity can all be selected or modified to provide a particular level of refrigeration. For example, the wall thicknesses and/or the space widths can be increased to increase the ability of the container chamber to maintain the desired temperature.
