   DETAILED DESCRIPTION 
     FIG. 1  is a perspective view of an exemplary embodiment of a cremains container and/or box-urn  1000 , which can be comprised of a first portion  1400  to which a lid  1500  is adapted to be attached. First portion  1400  can comprise a face  1300 , which can be substantially rectangular and/or substantially planar. First portion  1400  can comprise an opposing pair of sides  1100 ,  1150 , either of which can be substantially rectangular and/or substantially planar. First portion  1400  can comprise an opposing pair of ends  1200 ,  1250 , either of which can be substantially rectangular and/or substantially planar. Face  1300  can be interlocked to either or both of sides  1100 ,  1150 . Face  1300  can be interlocked to either or both of ends  1200 ,  1250 . Either or both of sides  1100 ,  1150  can be interlocked to either or both of ends  1200 ,  1250 . First portion  1400  can define a cremains cavity  1800 . Lid  1500  can be attached to first portion  1400  to close cremains cavity  1800  and form a cremains space  1900 . If lid  1500  is attached permanently to first portion  1400 , cremains space  1900  can be substantially airtight. Box-urn  1000  and/or first portion  1400  can be defined by a length UL, width UW, and/or height UH. In certain exemplary embodiments, the maximum value of UL, UW, and UH can be about 12 inches or less. In certain exemplary embodiments, box-urn  1000  and/or at least certain components thereof, can be manufactured from wood, such as walnut, oak, cherry, and/or pine. 
     FIG. 2  is a cross-sectional assembly view, taken along line A-A of  FIG. 1 , and  FIG. 3  is a cross-sectional assembly view, taken along line B-B of  FIG. 1 . Face  1300  can be attached to sides  1100 ,  1150 , and ends  1200 ,  1250  to form first portion  1400 . The attachment can utilize glue, such as a carpenter&#39;s and/or weatherproof glue, e.g., Tight-Bond II from Franklin International of Columbus, Ohio. The attachment can utilize a joint, such as a mortise and tenon and/or tongue and groove. For example, face  1300  can comprise one or more side grooves  1720  and/or one or more end grooves  1740  adapted to receive corresponding one or more side tongues  1620  and/or one or more end tongues  1640 . Note that the placement of and grooves and tongues, and/or mortises and tenons, is not critical, so long as a sturdy joint is formed. Thus, face  1300  can comprise one or more tongues and/or tenons. Although not shown, either of sides  1100 ,  1150  can be interlocked, such as via a joint, to either of ends  1200 ,  1250 . The joint can utilize glue, a mortise and tenon construction, and/or a tongue and groove construction. In certain exemplary embodiments, a tenon and/or tongue can have a round cross-section, such as a dowel, and the corresponding mortise and/or groove can have a round cross-section, such as a hole. 
   First portion  1400  can define a cremains cavity  1800  that can be enclosed to form a cremains space  1900  by attachment of lid  1500 , which can closely fit into first portion  1400  and onto a lid seat  1440 . Because cremains space  1900  can be substantially airtight, when placing lid  1500  on lid seat  1440 , a portion of the air within cremains cavity  1800  can escape from cremains cavity  1800  via vent holes  1540 , thereby allowing lid  1500  to mate flushly into first portion  1400 . Prior to mating lid  1500  to first portion  1400 , glue can be applied to lid seat  1440 , first portion  1400 , and/or lid  1500 , thereby allowing lid  1500  to be permanently sealed to first portion  1400 . Screws  1520 , which can be made of stainless steel, brass, etc., can project substantially through vent holes  1540  in lid  1500  and interface with receiving holes  1420  in first portion  1400  to attach lid  1500  to first portion  1400 , thereby applying sufficient pressure to help any applied glue set properly. Prior and/or afterwards to mating lid  1500  with seat  1440  and/or first portion  1400 , glue can be applied to screws  1520 , vent holes  1540 , and/or receiving holes  1420  to allow the interaction therebetween to seal vent holes  1540 , thereby rendering cremains space  1900  substantially airtight. In certain exemplary embodiments, cremains space  1900  can remain substantially airtight when exposed to temperatures ranging from about −30 F to about −300 F, including all values and subranges therebetween, such as from about −20 F to about 180 F. In certain exemplary embodiments, cremains space  1900  can comprise a volume of at least about 200 cubic inches. 
   In certain exemplary embodiments, a protective finish and/or sealant, such as a polyurethane wood finish, can be applied to an exterior surface  1320  of box-urn  1000  to help preserve box-urn  1000  and/or prevent moisture from penetrating box-urn  1000 . In certain exemplary embodiments, a pin, plate, and/or plaque, etc. can be adhered to an exterior surface  1320  of box-urn  1000 . In certain exemplary embodiments, the pin can relate to a civic society, social club, military unit and/or honor, etc. In certain exemplary embodiments, the plaque can be brass and/or can be engraved with information regarding the deceased, such as name, rank, unit of military service, civic society, birth date, death date, etc. In certain exemplary embodiments, a box-urn can measure approximately 7½ inches to approximately 7⅞ inches by approximately 3½ to approximately 3⅞ inches by approximately 11½ inches to approximately 11⅞ inches. In certain exemplary embodiments, exterior edges and/or corners of box-urn  1000  can be rounded and/or smooth to prevent injuries and/or to ease handling of box-urn  1000 .
