An alternative container in funeral practice is specifically defined as a nonmetal receptacle that is designed to hold human remains during the cremation process. The essential characteristic of an alternative container is its simplicity and functionality; it is typically made from materials such as cardboard, fiberboard, or pressed wood and is not intended for elaborate display or memorialization.
The emphasis on being "without ornamentation" signifies that its purpose is solely practical, providing a respectful way to contain the body without the additional features that might complicate its use or increase costs. This option aligns with regulations that are in place to ensure that families have access to affordable and straightforward options for cremation, particularly in situations where a more expensive or ornate casket might not be desired or feasible.
The other options, while they may describe types of containers, do not capture the specific requirements that define what an alternative container is in the context of funeral practice. For instance, a wooden or metal container may not meet the criteria of being nonmetal or lacking ornamentation, hence they do not fit the definition as clearly as the correct choice.
